    Full Text Available The study was performed on the base of 10 years of using different methods of analysis of heart rate variability as an indicator of direct and reverse connection of the sympatho-adrenal system in the preoperative diagnosis and anesthetic monitoring. The possibility of predicting the depth of anaesthesia was analyzed, for depending on significant amounts of external and internal conditions, the level of anesthesia changes significantly. In this regard the influence of drugs and technological means of influencing the condition of all life-supporting systems, and the autonomic nervous system in particular, before, during and after anesthesia is of great practical interest. The balance of the pharmacological protection of the vegetative balance in the surgical aggression is studied, as well as the use of heart rate variability as a non-specific method in relation to nosological forms of pathology, both under internal and external influences. A review of a number of sources confirms that heart rate is virtually the only high-speed method to present the sympatho-vagal regulation, the most accessible somatic parameter for estimation of the cardiovascular system functioning in anesthesiology. The heart rate variability serves as an indicator of functional condition of autonomous (vegetative nervous system. It is proposed to perform the continuous monitoring of the autonomic indices of the heart rhythm, which allows to register sympaho-vagal imbalance. Dynamic monitoring, timely interpretation of heart rate variability are constantly in the spotlight, but the approach and methodology of the domestic and foreign authors distinctly differ on the following points: heart rythmography as a visual method of assessing information about the dynamics of slow-wave processes, spectral analysis of the heart sinus rhythm as the best method of analysis of large and small wave activity, tests of functional diagnostics for subsequent measurement of the autonomic nervous

    Full Text Available Topical anesthetics are being widely used in numerous medical and surgical sub-specialties such as anesthesia, ophthalmology, otorhinolaryngology, dentistry, urology, and aesthetic surgery. They cause superficial loss of pain sensation after direct application. Their delivery and effectiveness can be enhanced by using free bases; by increasing the drug concentration, lowering the melting point; by using physical and chemical permeation enhancers and lipid delivery vesicles. Various topical anesthetic agents available for use are eutectic mixture of local anesthetics, ELA-max, lidocaine, epinephrine, tetracaine, bupivanor, 4% tetracaine, benzocaine, proparacaine, Betacaine-LA, topicaine, lidoderm, S-caine patch™ and local anesthetic peel. While using them, careful attention must be paid to their pharmacology, area and duration of application, age and weight of the patients and possible side-effects.

    Full Text Available Aims and Objectives: Cor triatriatum sinistrum (CTS and cor triatriatum dextrum (CTD are rare congenital anomalies characterized by the presence of a perforated septum which divides the respective atrium into a proximal and distal chamber. This report reviews the perioperative course of patients with uncorrected cor triatriatum (CT undergoing procedures requiring anesthesia. In addition, we performed a literature search that examines the experience of others regarding the peri-operative course of patients with CT. Materials and Methods: A computerized search of a medical record database was conducted to identify patients with a clinical diagnosis of uncorrected CTD and CTS undergoing surgical procedures. Descriptive statistics were used. Results: We identified 12 adult patients with asymptomatic CTS (n = 7 and CTD (n = 5 who underwent 23 anesthetics. There were no perioperative complications which could be attributed directly to the anatomy of CT. Conclusions: Our observation and review of the literature suggest that patients with asymptomatic CT typically tolerate anesthesia and surgical procedures well.

    Full Text Available Pain control during the dental procedure is essentials and challenging. A complete efficacious pulp anesthesia has not been attained yet. The regional anesthesia such as inferior alveolar nerve block (IANB only does not guarantee the effective anesthesia with patients suffering from irreversible pulpitis. This main aim of this review was to discuss various aspects of intraseptal dental anesthesia and its role significance in pain-free treatment in the dental office. In addition, reasons of failure and limitations of this technique have been highlighted. Literature search was conducted for peer-reviewed articles published in English language in last 30 years. Search words such as dental anesthesia, pain control, intraseptal, and nerve block were entered using a web of knowledge and Google scholar databases. Various dental local anesthesia techniques were reviewed. A combination of block anesthesia, buccal infiltration and intraligamentary injection resulted in deep anesthesia (P = 0.003, and higher success rate compared to IANB. For pain-free management of conditions such as irreversible pulpitis, buccal infiltration (4% articaine, and intraosseous injection (2% lidocaine are better than intraligamentary and IANB injections. Similarly, nerve block is not always effective for pain-free root canal treatment hence, needing supplemental anesthesia. Intraseptal anesthesia is an efficient and effective technique that can be used in maxillary and mandibular adult dentition. This technique is also beneficial when used in conjunction to the regional block or local dental anesthesia.

    Various EEG features have been used in depth of anesthesia (DOA) studies. The objective of this study was to find the excellent features or combination of them than can discriminate between different anesthesia states. Conducting a clinical study on 22 patients we could define 4 distinct anesthetic states: awake, moderate, general anesthesia, and isoelectric. We examined features that have been used in earlier studies using single-channel EEG signal processing method. The maximum accuracy (99.02%) achieved using approximate entropy as the feature. Some other features could well discriminate a particular state of anesthesia. We could completely classify the patterns by means of 3 features and Bayesian classifier.

    The specific problems of outpatient anesthesia are discussed with respect to the patient's condition, the anesthesist's qualification and pharmacological properties of anesthetics used. Methohexitone seems to be the best choice for induction. Problems may arise from the use of Propanidid, Ketamin and Diazepam. Nitrousoxide and Enflurane are a suitable completion. Endotracheal intubation, if needed, is facilitated by Suxamethonium, which is rapidly eliminated. Practical aspects of timing, premedication, induction, maintenance and ending of anesthesia are pointed out. After 1-2 hours the patient can be allowed to leave the hospital accompanied by a responsible person. Driving a car is not recommended before 24 hours have elapsed since anesthesia.

    Anesthesia is considered a leading discipline in the field of patient safety. Nevertheless, complications still occur and can be devastating. A substantial portion of anesthesia-related adverse events are preventable since risk factors can be detected and eliminated. Risk management (RM) in anesthesia includes preventive and remedial measures to minimize patient anesthesia-related morbidity and mortality. RM involves all aspects of anesthesia care. Classically, the following four steps are needed to prevent critical incidents or to learn from them: (1) detection of problems, (2) assessment, (3) implementation of solutions, and (4) verification of effectiveness. Problems and solutions can be identified into the fields of structures, processes and personnel. Authoritative agencies like the World Health Organization, the World Federation of Societies of Anesthesiologists, the Section and Board of Anesthesiology of the European Union of Medical Specialties and the Italian Scientific Society of Anesthesiologists (Società Italiana di Anestesia, Analgesia, Rianimazione e Terapia Intensiva SIAARTI) have proposed initiatives addressing safety in the operating room. The central role of a well-trained, constantly present anesthesiologist and the usefulness of checklists have been highlighted. Cost cutting and production pressure in medical care are potential threats to safety. A shared knowledge of the best standards of care and of the potential consequences of unscrupulous actions could make the daily management of conflicting interests easier. A correctly applied RM can be a powerful, highly beneficial aid to our practice.

    Objectives: To examine the anesthesiologist’s choice for anesthesia techniques and drugs in circumcision and determine the preoperative examination, intraoperative monitoring techniques, postoperative analgesia methods, and common complications among anesthesiologists working in Turkey. Methods: This cross-sectional study was conducted at Bulent Ecevit University Hospital, Zonguldak, Turkey, between May and July 2012. Survey data were obtained via survey forms through electronic data over the web. The questionnaire consists of 20 questions. These questions included demographic data, methods of anesthesia for circumcision, postoperative analgesia methods, and monitoring methods. Results: The data were obtained from 206 anesthesiologists who agreed to participate in the survey. Circumcision was performed most frequently in the age group of 3-6 years old. It was found that 47% of routine preoperative laboratory tests were coagulation parameters and complete blood count tests. The most common method of anesthesia was laryngeal mask. The frequency of administration of regional anesthesia was 37.4%, and caudal block was more preferable. Bupivacaine as a local anesthetic in regional anesthesia and midazolam and ketamine were the most preferred agents in sedoanalgesia. During regional anesthesia, ultrasound was most often used by anesthesiologists (31.6%). Conclusion: Ambulatory anesthesia protocols, which are also needed in circumcision, can be improved with international recommendation, and these protocols could be conformed as sociocultural structure in societies. This study should be regarded as a preliminary study to attract attention on anesthesia techniques in circumcision. PMID:28042634

    2012-01-01

    Documenting a patient's anesthetic in the medical record is quite different from summarizing an office visit, writing a surgical procedure note, or recording other clinical encounters. Some of the biggest differences are the frequent sampling of physiologic data, volume of data, and diversity of data collected. The goal of the anesthesia record is to accurately and comprehensively capture a patient's anesthetic experience in a succinct format. Having ready access to physiologic trends is essential to allowing anesthesiologists to make proper diagnoses and treatment decisions. Although the value provided by anesthesia information management systems and their functions may be different than other electronic health records, the real benefits of an anesthesia information management system depend on having it fully integrated with the other health information technologies. An anesthesia information management system is built around the electronic anesthesia record and incorporates anesthesia-relevant data pulled from disparate systems such as laboratory, billing, imaging, communication, pharmacy, and scheduling. The ability of an anesthesia information management system to collect data automatically enables anesthesiologists to reliably create an accurate record at all times, regardless of other concurrent demands. These systems also have the potential to convert large volumes of data into actionable information for outcomes research and quality-improvement initiatives. Developing a system to validate the data is crucial in conducting outcomes research using large datasets. Technology innovations outside of healthcare, such as multitouch interfaces, near-instant software response times, powerful but simple search capabilities, and intuitive designs, have raised the bar for users' expectations of health information technology.

    The Accreditation Council for Graduate Medical Education requires that residency programs teach residents about handoffs and ensure their competence in this communication skill. Development of hand-off curricula for anesthesia residency programs is hindered by the paucity of evidence regarding how to conduct, teach, and evaluate handoffs in the various settings where anesthesia practitioners work. This narrative review draws from literature in anesthesia and other disciplines to provide recommendations for anesthesia resident hand-off curriculum development and evaluation.

    Full Text Available Acute paraplegia is a rare but catastrophic complication of surgeries performed on aorta and corrective operations of vertebral column. Trauma to spinal cord after spinal anesthesia and ischemia of spinal cord also may lead to acute paraplegia. Acute paraplegia as a complication of general anesthesia in surgeries performed on sites other than aorta and vertebral column is very rare. Here we present a 56 year old woman with acute paraplegia due to spinal cord infarction after laparoscopic cholecystectomy under general anesthesia probably caused by atherosclerosis of feeding spinal arteries and ischemia of spinal cord after reduction of blood flow possibly due to hypotension during general anesthesia.

    In most instances, delayed emergence from anesthesia is attributed to residual anesthetic or analgesic medications. However, delayed emergence can be secondary to unusual causes and present diagnostic dilemmas. Data from clinical studies is scarce and most available published material is comprised of case reports. In this review, we summarize and discuss less common and difficult to diagnose reasons for delayed emergence and present cases from our own experience or reference published case reports/case series. The goal is to draw attention to less common reasons for delayed emergence, identify patient populations that are potentially at risk and to help anesthesiologists identifying a possible cause why their patient is slow to wake up.

    Anesthesia and surgery are associated with significantly increased morbidity and mortality in patients with pulmonary hypertension due mainly to right ventricular failure, arrhythmias, postoperative hypoxemia, and myocardial ischemia. Preoperative risk assessment and successful management of patients with pulmonary hypertension undergoing cardiac surgery involve an understanding of the pathophysiology of the disease, screening of patients at-risk for pulmonary arterial hypertension, analysis of preoperative and operative risk factors, thorough multidisciplinary planning, careful intraoperative management, and early recognition and treatment of postoperative complications. This article will cover each of these aspects with particular focus on the anesthetic approach for non-cardiothoracic surgeries.

    A strong tendency toward body enhancement and body forming in western industrial societies makes it more likely for each anesthesiologist to get involved in the care of bodybuilders. These patients quite frequently consume androgenic anabolic steroids, human growth hormone and other drugs or substances which are believed to accelerate muscle gain. Cardiovascular, hepatic, psychiatric, hormonal and infectious side effects or complications are common and rarely monitored by health care professionals. The anesthesia risk is not exactly known but seems to be determined mainly by cardiovascular events like myocardial ischemia and dysrhythmias.

    Regional anesthesia has been widely applied as an excellent method for perioperative analgesia. Recent studies suggested that regional anesthesia is a promising approach to minimize the risk of surgical site infection and postoperative cancer recurrence, subsequently providing the benefits to the long-term outcome. In particular, it is of great interest that regional anesthesia might be able to reduce cancer recurrence. In cancer patients, innate immunity against cancer could be depressed, resulting in the predisposition to evoke metastasis. Besides, during the perioperative periods, tumor immunity is significantly depressed due to surgical pain, activation of sympathetic nervous system, inflammatory responses, and others. In this review article, we discuss the tumor immunity during the perioperative period, with focus on the alterations of tumor immunity and regional anesthesia.

    2006-01-01

    Full Text Available Spinal anesthesia is widely used during surgical procedures. It is generally safe and the frequency of severe, permanent neurological complications associated with it has been reported to be extremely low. We report a patient, who developed paraplegia following spinal anesthesia. A 29-year-old male was referred with acute, flaccid, sensory motor paraplegia, with bladder and bowel involvement. He developed this immediately after an operation for inguinal hernia under spinal anesthesia. Spinal magnetic resonance imaging revealed hemorrhagic myelitis in the conus at D12. He was referred after he did not respond to intravenous methylprednisolone for 10 days. This case brings up the difficulty encountered in determination of the interspace used for spinal anesthesia and the potential for traumatic injury to the spinal cord. It also demonstrates the tragic outcome after a clinician violates some important, standard and established guidelines.

    Abstract Inhalation anesthetics provide myocardial protection for cardiac surgery. This study was undertaken to compare the perioperative effects between isoflurane and fentanyl-midazolam-based anesthesia for heart transplantation. A retrospective cohort study was conducted by reviewing the medical records of heart transplantation in a single medical center from 1990 to 2013. Patients receiving isoflurane or fentanyl-midazolam-based anesthesia were included. Those with preoperative severe pulmonary, hepatic, or renal comorbidities were excluded. The perioperative variables and postoperative short-term outcomes were analyzed, including blood glucose levels, urine output, inotropic use, time to extubation, and length of stay in the intensive care units. After reviewing 112 heart transplantations, 18 recipients with fentanyl-midazolam-based anesthesia, and 29 receiving isoflurane anesthesia with minimal low-flow technique were analyzed. After cessation of cardiopulmonary bypass, recipients with isoflurane anesthesia had a significantly lower mean level and a less increase of blood glucose, as compared with those receiving fentanyl-based anesthesia. In addition, there was less use of dobutamine upon arriving the intensive care unit and a shorter time to extubation after isoflurane anesthesia. Compared with fentanyl-midazolam-based anesthesia, isoflurane minimal low-flow anesthesia maintained better perioperative homeostasis of blood glucose levels, less postoperative use of inotropics, and early extubation time among heart-transplant recipients without severe comorbidities.

  16. Anesthesia for outpatient female sterilization.

    Fishburne, J I

    1983-04-01

    This issue of the Bulletin deals with the principles of anesthesia for outpatient female sterilization with emphasis on techniques for laparoscopy and minilaparotomy. General anesthesia techniques provide analgesia, amnesia, and muscle relaxation and are particularly useful for managing the anxious patient. Disadvantages include increased expense, need for specialized equipment, and highly trained personnel, and delayed recovery. Complications, though relatively rare, can be life-threatening and include aspiration of stomach contents, hypoxia, hypercarbia, hypotension, hypertension, cardiac arrhythmias, cardiorespiratory arrest, and death. There is no single preferred technique of general anesthesia, athough most anesthetists employ methods that allow rapid recovery of faculties, enabling the patient to be discharged soon after surgery. To accomplish this end, light anesthesia with sodium thiopental induction and nitrous oxide maintenance is often used. Short duration muscle relaxation with an agent such as succinylcholine supplements this technique. Other techniques include light anesthesia with inhalational anesthetic agents and the use of intravenous ketamine. Local anesthesia augmented by systemic and/or inhalational analgesia is supplanting general anesthesia techniques for laparoscopy in many locales. This approach is also particularly well-suited for minilaparotomy in developing countries, where it has achieved its greatest popularity. The local technique carries with it reduced morbidity and mortality but may not entirely relieve discomfort. The primary danger of local anesthesia is respiratory depression due to excessive narcosis and sedation. The operator must be alert to the action of the drugs and should always use the minimal effective dose. Although toxicity due to overdosage with local anesthetic drugs is occasionally experienced, allergic reactions to the amide-linkage drugs such as lidocaine or bupivacaine are exceedingly rare.

    Experience obtained from adenotomy (AT) under general anesthesia using Ketamin hydrochloride (Ketalar, Narkamon) in children are presented in this paper. The authors had used intramuscular premedication with Prothazin, Dolsin and Atropin at the first stage, then they shifted to oral administration of a combination of Diazepam, Theadryl and Atropin. Ketamin may be applied intravenously in the dosage of 1.0 to 1.5 mg/kg of body weight in most children. Where it is not possible, a triple dose into the muscle is used. A total of 2,266 AT were performed. About 70% of patients were calm during the operation, once a suspected aspiration was considered but it was not confirmed. The main contribution of the method is 100% amnesia of the surgery made. The procedure is a compromise between a requirement for minimal traumatization of the child's psyche by the intervention and the resources available, particularly the need of personnel at the majority of otorhinolaryngo-logical departments nowadays.

    The elaboration of more reliable and simple methods of transmitted and plexus anestesias has provided a wide clinical usage of regionar anestesia (RA) during the operations on extremities. The creation of devices to identificate (locate) nerval bearer and plexes was also an important factor for increasing quantity of RA. For such identification we use the portable "Innervator 232" neurostimulator manufactured by "Fisher & Paykel Ltd.", New Zealand. Successful conduction of transmitted and plexus anesthesia depends a lot on anesthesiologist's knowledge of anatomy-topography location of nerval bearer and plexes, precise fulfillment of anesthesia, manual capabilities of physician and obtaining a paresthesia or muscular contraction during the identification of nerval bearer with the help of neurostimulator. RA is secure, effective, and provides less risk for a patient. With neurostimulation the amount of successful anesthesias increases up to 98%. The neurostimulator is easy to use, clinically effective in emergency and planned surgeries for identification of nerval bearer and plexes.

    Objective of this investigation is to further analyze the cardiac function status change by phonocar diogram during mixed anesthesia which is conducted by midazolam, skelaxin, fentanyi and propofoL The results show that blood pressure, heart rate, amplitude of R wave and T wave, amplitude of first heart sound (Si) and second heart sound (52) about 37 subjects after anesthesia decrease compared with baseline, while the. ratio of first heart sound and second heart sound (Si/S2) and the ratio of diastole duration and systole duration (DIS) increase. Our study demonstrates that phonocardiogram as a noninvasive, high benefit/cost ratio, objective, repeatable and portable method can be used for the monitoring and evaluation of cardiac function status during anesthesia and operations.

    Diverse molecules induce general anesthesia with potency strongly correlated both with their hydrophobicity and their effects on certain ion channels. We recently observed that several anesthetics inhibit heterogeneity in plasma membrane derived vesicles by lowering the critical temperature ($T_c$) for phase separation. Here we exploit conditions that stabilize membrane heterogeneity to test the correlation between the anesthetic potency of n-alcohols and effects on $T_c$. First we show that hexadecanol acts oppositely to anesthetics on membrane mixing and antagonizes ethanol induced anesthesia in a tadpole behavioral assay. Second, we show that two previously described `intoxication reversers' raise $T_c$ in vesicles and counter ethanol's effects in vesicles, mimicking the findings of previous electrophysiological measurements. Third, we find that hydrostatic pressure, long known to reverse anesthesia, also raises $T_c$ in vesicles with a magnitude that counters the effect of an anesthetic at relevant concen...

    This article covers the manual restraint and anesthesia of marsupials, insectivores, and chiroptera. Marsupials commonly kept as pets in the U.S. [e.g., eastern gray kangaroos (Macropus giganteus), Bennett's wallabies (Macropus rufogriseus), and sugar gliders (Petaurus breviceps)] are covered in detail. Marsupial species kept in zoological parks [e.g., Tasmanian devils, koalas (Phascolarctos cinereus), and common wombats (Vombatus ursinus)] are covered in less detail. Of the insectivores, only the African hedgehog (Atelerix albiventris) and the European hedgehog (Erinaceus europaeus) are commonly kept as pets and, consequently, the insectivore section concentrates on discussing these two species. The section on chiropteran anesthesia is divided into two broad categories: the megachiropterans (flying foxes and fruit bats) and the microchiropterans (insectivorous bats). Most of the information on the species covered in this article is anecdotal, and this should be kept in mind when using the anesthesia protocols described.

    We have developed an anesthesia information system (AIS) that supports the anesthesiologist in monitoring and recording during a surgical operation. In development of the system, emphasis was placed on providing an anesthesiologist-computer interface that can be adapted to typical situations during anesthesia and to individual user behavior. One main feature of this interface is the integration of the input and output of information. The only device for interaction between the anesthesiologist and the AIS is a touch-sensitive, high-resolution color display screen. The anesthesiologist enters information by touching virtual function keys displayed on the screen. A data window displays all data generated over time, such as automatically recorded vital signs, including blood pressure, heart rate, and rectal and esophageal temperatures, and manually entered variables, such as administered drugs, and ventilator settings. The information gathered by the AIS is presented on the cathode ray tube in several pages. A main distributor page gives an overall view of the content of every work page. A one-page record of the anesthesia is automatically plotted on a multicolor digital plotter during the operation. An example of the use of the AIS is presented from a field test of the system during which it was evaluated in the operating room without interfering with the ongoing operation. Medical staff who used the AIS imitated the anesthesiologist's recording and information search behavior but did not have responsibility for the conduct of the anesthetic.

    Full Text Available Objective: Entropy algorithms have been widely used in analyzing EEG signals during anesthesia. However, a systematic comparison of these entropy algorithms in assessing anesthesia drugs’ effect is lacking. In this study, we compare the capability of twelve entropy indices for monitoring depth of anesthesia (DoA and detecting the burst suppression pattern (BSP, in anesthesia induced by GA-BAergic agents.Methods: Twelve indices were investigated, namely Response Entropy (RE and State entropy (SE, three wavelet entropy (WE measures (Shannon WE (SWE, Tsallis WE (TWE and Renyi WE (RWE, Hilbert-Huang spectral entropy (HHSE, approximate entropy (ApEn, sample entropy (SampEn, Fuzzy entropy, and three permutation entropy (PE measures (Shannon PE (SPE, Tsallis PE (TPE and Renyi PE (RPE. Two EEG data sets from sevoflurane-induced and isoflu-rane-induced anesthesia respectively were selected to assess the capability of each entropy index in DoA monitoring and BSP detection. To validate the effectiveness of these entropy algorithms, phar-macokinetic / pharmacodynamic (PK/PD modeling and prediction probability analysis were applied. The multifractal detrended fluctuation analysis (MDFA as a non-entropy measure was compared.Results: All the entropy and MDFA indices could track the changes in EEG pattern during different anesthesia states. Three PE measures outperformed the other entropy indices, with less baseline vari-ability, higher coefficient of determination and prediction probability, and RPE performed best; ApEn and SampEn discriminated BSP best. Additionally, these entropy measures showed an ad-vantage in computation efficiency compared with MDFA.Conclusion: Each entropy index has its advantages and disadvantages in estimating DoA. Overall, it is suggested that the RPE index was a superior measure.Significance: Investigating the advantages and disadvantages of these entropy indices could help improve current clinical indices for monitoring DoA.

  5. The thermodynamics of general anesthesia

    2006-01-01

    It is known that the action of general anesthetics is proportional to their partition coefficient in lipid membranes (Meyer-Overton rule). This solubility is, however, directly related to the depression of the temperature of the melting transition found close to body temperature in biomembranes. We propose a thermodynamic extension of the Meyer-Overton rule which is based on free energy changes in the system and thus automatically incorporates the effects of melting point depression. This model provides a quantitative explanation of the pressure reversal of anesthesia. Further, it explains why inflammation and the addition of divalent cations reduce the effectiveness of anesthesia.

    This study was designed to evaluate the influence of inhalational agents on the intestinal circulation in an isolated loop preparation. Sixty dogs were studied, using three intestinal segments from each dog. Selected intestinal segments were pumped with aortic blood at a constant pressure of 100 mmHg. A mixture of /sub 86/Rb and 9-microns spheres labeled with /sup 141/Ce was injected into the arterial cannula supplying the intestinal loop, while mesenteric venous blood was collected for activity counting. A very strong and significant correlation was found between rubidium clearance and microsphere entrapment (r = 0.97, P less than 0.0001). Nitrous oxide anesthesia was accompanied by a higher vascular resistance (VR), lower flow (F), rubidium clearance (Cl-Rb), and microspheres entrapment (Cl-Sph) than pentobarbital anesthesia, indicating that the vascular bed in the intestinal segment was constricted and flow (total and nutritive) decreased. Halothane, enflurane, and isoflurane anesthesia were accompanied by a much lower arteriovenous oxygen content difference (AVDO/sub 2/) and oxygen uptake than pentobarbital or nitrous oxide. Compared with pentobarbital, enflurane anesthesia was not accompanied by marked differences in VR, F, Cl-Rb, and Cl-Sph; halothane at 2 MAC decreased VR and increased F and Cl-Rb while isoflurane increased VR and decreased F. alpha-Adrenoceptor blockade with phentolamine (1 mg . kg-1) abolished isoflurane-induced vasoconstriction, suggesting that the increase in VR was mediated via circulating catecholamines.

    Full Text Available Any site in the upper airway can get obstructed and cause noisy breathing as well as dyspnea. These include nasal causes such as choanal atresia or nasal stenosis; pharyngeal causes including lingual thyroid; laryngeal causes such as laryngomalacia; tracheobronchial causes such as tracheal stenosis; and subglottic stenosis. Lesions in the oropharynx may cause stertor, while lesions in the laryngotracheal tree will cause stridor. Subglottic stenosis is the third leading cause of congenital stridors in the neonate. Subglottic Stenosis presents challenges to the anesthesiologist. Therefore, It is imperative to perform a detailed history, physical examination, and characterization of the extent and severity of stenosis. Rigid endoscopy is essential for the preoperative planning of any of the surgical procedures that can be used for correction. Choice of operation is dependent on the surgeon′s comfort, postoperative capabilities, and severity of disease. For high-grade stenosis, single-stage laryngotracheal resection or cricotracheal resection are the best options. It has to be borne in mind that the goal of surgery is to allow for an adequate airway for normal activity without the need for tracheostomy. Anesthesia for airway surgery could be conducted safely with either sevofl uraneor propofol-based total intravenous anesthesia.

    Local anesthesia is without doubt the most frequently used drug in dentistry and in medicine. In spite of records of safety set by using these drugs, there is evidence to adverse reactions ranging from 2.5%-11%. Most of the reactions originate from the autonomic system. A recent, well-planned study indicates that adverse reactions are highly correlated to the medical status of the patient: the higher the medical risk, the greater the chance to experience an adverse reaction. This study also found that adverse reactions highly correlated to the concentration of adrenalin. Another recent study found a direct relationship between adverse reactions and the level of anxiety experienced by the patient and to the dental procedure. Most of the reactions in this study occurred either immediately at injection time and within 2 hours following the injection. Since the beginning of last century, vasoconstrictors have been added to local anesthesia solutions in order to reduce toxicity and prologue activity of the LA. However, today it is commonly agreed that this addition to local anesthesia should not be administered to cardiac patients especially those suffering from refractory dysrhythmias, angina pectoris, post myocardial infarction (6 months) and uncontrolled hypertension. Other contraindications to vasoconstrictors are endocrine disorders such as hyperthyroidism, hyperfunction of the medullary adrenal (pheochromocytoma) and uncontrolled diabetes mellitus. Cross reactivity of local anesthetic solutions can occur with MAO inhibitors, non specific beta adrenergic blockers, tricyclic antidepressants, phenothiazides and cocaine abusers. Noradrenaline added to local anesthetics as a vasoconstrictor has been described as a trigger to a great increase in blood pressure and therefore has been forbidden for use in many countries. This paper describes 4 cases of severe complications following the injections of local anesthesia of which three ended in fatality.

    General anesthesia in ophthalmological surgery has become a great fashion. However there are still many problems especially in intraocular surgery. The eye with normal intraocular pressure generally needs no special technique. Most of the usual anesthesia produce a slight hypotonia with the exception of Succinylcholine, whose effect is contrary. Unfortunately this is not the case in eyes with pathologically increased intraocular pressure as in the different forms of glaucoma. Eye surgeons and anesthesists therefore look for solutions to this problem which in principle consist in the application of medicaments, which not seldom are rather agressive. The controlled hypotension by ganglion blockers, the curarisation in the state of being awake, the rapid perfusion of solutions with high osmotique effect (isolated or associated) represent such measures. The one has the disadvantage to be applied during so-called subvigile anesthesias where the security that the patient is asleep is rather doubtful; the other has the disadvantage that it requires a rapid perfusion of solutions with highly osmotic effect. It goes without saying that these conditions represent risks especially if one considers that the candidates for this type of intervention very often are senile persons with prearious cardiovascular equilibrium, with insufficient renal function and with insufficient arterial cerebral circulation. These are some of the problems which are to be discussed.

    Jyotsna S Paranjpe

    2013-01-01

    Full Text Available The potential uses of dexmedetomidine (DEX, a highly selective α2 - adrenoceptor agonist are very diverse. DEX appears to mimic many of the actions of mythical ′ideal′ sedative/analgesic agent. Although not orally active, DEX shows good bioavailability when administered via various other routes like intranasal, buccal, IM than intra-venous. DEX has similar pharmacokinetics in all age groups. Its side effects are predictable and easily treatable, hence it has found place as a part of fast-tracking anesthesia regimens in children. DEX is the sedative of choice for peri-operative use in high risk patients, since it is cardioprotective, neuroprotective and renoprotective. Premedication with DEX obtunds the autonomic pressor responses due to laryngoscopy and endotracheal intubation when used as an adjuvant to general anesthesia. DEX in high doses offers another approach to managing morbidly obese patients and patients with a compromised airway; without causing any cardio-respiratory depression. It is near ideal hypotensive agent used for controlled hypotension. Its value as a primary sedative and analgesic is becoming more accepted and evident in critically ill patients; in adult and paediatric intensive care units. Besides use in locoregional anesthesia, it is also used as an opioid substitute, for treatment of substance withdrawal, as an anti-shivering agent, for treatment of delirium and as an end of life medication. Availability of an antidote (Atipamezole with similar elimination half life is taking the drug into new frontiers. However, use of DEX is contraindicated in patients with hepatic failure, hypovolemic shock, advanced heart block or ventricular dysfunction.

    Results of carotid endarterectomy (CEAE) in 193 patients with different degree of cerebrovascular insufficiency were analyzed. All the patients were men with carotid atherosclerosis (age from 39 to 68 years, mean age 53.6 +/- 0.4). A total of 253 CEAEs were performed under local anesthesia (60 patients underwent consecutive bilateral operations). In early postoperative period 3 patients died, one of them--of ischemic stroke due to thrombosis of internal carotid artery on the side of the operation. Non-fatal stroke was in 1 patient. There were no intraoperative cerebral complications. This testifies to reliability of cerebral circulation control through direct contact with patient.

    Age-related hearing impairment, or presbycusis, is a degenerative condition not currently treatable by medication. It is therefore significant that the author, as a patient, experienced a reversal of high-frequency hearing loss during a 2-day period following abdominal surgery with general anesthesia. This report documents the surgery and the subsequent restoration of hearing, which was bilateral and is estimated to have exceeded 50dB at 4kHz. A possible role is noted for anesthetic agents such as lidocaine, propofol, or fentanyl. This experience may hold a clue for research toward the development of medical treatments for presbycusis.

  6. Acute onset of intracranial subdural hemorrhage five days after spinal anesthesia for knee arthroscopic surgery: a case report

    Full Text Available Abstract Introduction Spinal anesthesia is a widely used general purpose anesthesia. However, serious complications, such as intracranial subdural hemorrhage, can rarely occur. Case presentation We report the case of a 73-year-old Japanese woman who had acute onset of intracranial subdural hemorrhage five days after spinal anesthesia for knee arthroscopic surgery. Conclusion This case highlights the need to pay attention to acute intracranial subdural hemorrhage as a complication after spinal anesthesia. If the headache persists even in a supine position or nausea occurs abruptly, computed tomography or magnetic resonance imaging of the brain should be conducted. An intracranial subdural hematoma may have a serious outcome and is an important differential diagnosis for headache after spinal anesthesia.

    The partial intravenous anesthesia technique (PIVA) is used to lower the inspired concentration of an inhalational anesthetic by concurrent use of injectable drugs. This technique reduces the incidence of undesirable side-effects and provides superior quality of anesthesia and analgesia. Drugs commonly used for PIVA include opioids, alpha-2 adrenergic agonists, injectable anesthetic agents, and lidocaine. Most are administered by intravenous infusion.

    Studies determining anesthesia mortality rates in dentistry have been published, yet a similar investigation has never been conducted in Canada. Therefore the objective of this study was to determine the incidence of mortality when general anesthesia or deep sedation was administered by qualified dentists in the province of Ontario. Mortality data were obtained from the years 1973 to 1995 inclusive. The number of general anesthetics and deep sedations administered annually by qualified in dental offices was calculated by surveying all oral and maxillofacial surgeons and dental anesthetists in Ontario in 1990 and 1995. The results provided an estimate of 2,830,000 cases from 1973 to 1995 inclusive. Over this time period there were four deaths associated with cases in which either an oral and maxillofacial surgeon or dental anesthetist administered the general anesthetic or deep sedation, yielding a mortality rate of 1.4 per 1,000,000. This mortality incidence is similar to rates already published for outpatient dentistry.

    1993-11-01

    Spinal anesthetic is a common form of surgical anesthetic used in foot and ankle surgery. Spinal morphine anesthetic is less common, but has the advantage of providing postoperative analgesia for 12 to 24 hr. A number of complications can occur with spinal anesthesia, including urinary retention that may be a source of severe and often prolonged discomfort and pain for the patient. Management of this problem may require repeated bladder catheterization, which may lead to urinary tract infections or impairment of urethrovesicular function. This study reviews the incidence of urinary retention in 80 patients (40 after general anesthesia and 40 after spinal anesthesia) who underwent foot and ankle surgery at Saint Joseph's Hospital, Philadelphia, PA. Twenty-five percent of the patients who had spinal anesthesia experienced urinary retention, while only 7 1/2% of the group who had general anesthesia had this complication. Predisposing factors, treatment regimen, and recommendations for the prevention and management of urinary retention are presented.

    Full Text Available This systematic review of the Brazilian and worldwide literature aims to evaluate the incidence and causes of perioperative and anesthesia-related mortality. Studies were identified by searching the Medline and Scielo databases, followed by a manual search for relevant articles. Our review includes studies published between 1954 and 2007. Each publication was reviewed to identify author(s, study period, data source, perioperative mortality rates, and anesthesia-related mortality rates. Thirty-three trials were assessed. Brazilian and worldwide studies demonstrated a similar decline in anesthesia-related mortality rates, which amounted to fewer than 1 death per 10,000 anesthetics in the past two decades. Perioperative mortality rates also decreased during this period, with fewer than 20 deaths per 10,000 anesthetics in developed countries. Brazilian studies showed higher perioperative mortality rates, from 19 to 51 deaths per 10,000 anesthetics. The majority of perioperative deaths occurred in neonates, children under one year, elderly patients, males, patients of ASA III physical status or poorer, emergency surgeries, during general anesthesia, and cardiac surgery followed by thoracic, vascular, gastroenterologic, pediatric and orthopedic surgeries. The main causes of anesthesia-related mortality were problems with airway management and cardiocirculatory events related to anesthesia and drug administration. Our systematic review of the literature shows that perioperative mortality rates are higher in Brazil than in developed countries, while anesthesia-related mortality rates are similar in Brazil and in developed countries. Most cases of anesthesia-related mortality are associated with cardiocirculatory and airway events. These data may be useful in developing strategies to prevent anesthesia-related deaths.

    Full Text Available Cognitive disorders such as post-operative cognitive dysfunction, confusion, and delirium, are common following anesthesia in the elderly, with symptoms persisting for months or years in some patients. Alzheimer's disease (AD patients appear to be particularly at risk of cognitive deterioration following anesthesia, and some studies suggest that exposure to anesthetics may increase the risk of AD. Here, we review the literature linking anesthesia to AD, with a focus on the biochemical consequences of anesthetic exposure on AD pathogenic pathways.

  13. Leaving More Than Your Fingerprint on the Intravenous Line: A Prospective Study on Propofol Anesthesia and Implications of Stopcock Contamination

    2013-01-01

    Introduction Acute care handling of IV stopcocks during anesthesia and surgery may result in contaminated IV tubing sets. In the context of widespread propofol use, a nutrient-rich hypnotic drug, we hypothesized that propofol anesthesia increases bacterial contamination of IV stopcocks and may compromise safety of IV tubing sets when continued to be used after propofol anesthesia. Methods We conducted an in vitro trial by collecting IV tubing sets at the time of patient discharge from same-day ambulatory procedures performed with and without propofol anesthesia. These extension sets were then held at room temperature for 6, 24, or 48 hours. We cultured 50 samples at each interval for both cohorts. Quantitative cultures were done by aspirating the IV stopcock dead space and plating the aspirate on blood agar for colony count and speciation. Results Positive bacterial counts were recovered from 17.3% of propofol anesthesia stopcocks (26/150) and 18.6% of non-propofol stopcocks (28/150). At 6 hours, the average bacterial counts from stopcocks with visible residual propofol was 44 colony forming units (CFU)/mL, compared to 41 CFU/mL with no visible residual propofol and 37 CFU/mL in non-propofol anesthesia stopcocks. There was a 100-fold increase in bacterial number in contaminated stopcock dead spaces at 48 hours after propofol anesthesia. This difference remained significant when comparing positive counts from stopcocks with no visible residual propofol and non-propofol anesthesia (p-value=0.034). Conclusion There is a covert incidence and degree of IV stopcock bacterial contamination during anesthesia which is aggravated by propofol anesthetic. Propofol anesthesia may increase risk for postoperative infection because of bacterial growth in IV stopcock dead spaces. PMID:23749446

    2016-04-01

    This study sought to measure current attitudes toward hypnosis among anesthesia providers using an in-person survey distributed at a single grand rounds at a single academic teaching hospital. One hundred twenty-six anesthesia providers (anesthesiologists and nurse anesthetists) were included in this study. A 10-question Institutional Review Board (IRB)-approved questionnaire was developed. One hundred twenty-six (73% of providers at the meeting) anesthesia providers completed the survey. Of the respondents, 54 (43%) were anesthesiologists, 42 (33%) were trainees (interns/residents/fellows) in anesthesia, and 30 (24%) were nurse anesthetists. Over 70% of providers, at each level of training, rated their knowledge of hypnosis as either below average or having no knowledge. Fifty-two (42%) providers agreed or strongly agreed that hypnotherapy has a place in the clinical practice of anesthesia, while 103 (83%) believed that positive suggestion has a place in the clinical practice of anesthesia (p hypnosis were that it is too time consuming (41%) and requires special training (34%). Only three respondents (2%) believed that there were no reasons for using hypnosis in their practice. These data suggest that there is a self-reported lack of knowledge about hypnosis among anesthesia providers, although many anesthesia providers are open to the use of hypnosis in their clinical practice. Anesthesia providers are more likely to support the use of positive suggestion in their practice than hypnosis. Practical concerns should be addressed if hypnosis and therapeutic verbal techniques are to gain more widespread use.

    The authors have conducted a retrospective study on 115 patients with myasthenia gravis undergoing transsternal or transcervical thymectomy at the Policlinico A. Gemelli of Rome in the period June 1984- to June 1991. A prolonged postoperative mechanical ventilation immediately and a few days following surgery was required respectively in 7 and 3 patients, while atelectasia and broncopneumonia have developed in 10 patients. No relationship could be established between the incidence of respiratory complications and factors such as preoperative symptomatology and treatment anesthetic agents, the surgical approach to the thymus and thymic pathology. However a significantly greater postoperative morbidity has been observed in the group of patients receiving suxametonium as compared to the patients receiving non-depolarizing muscle relaxants. Vecuronium and atracurium very frequently allowed ad adequate resumption of spontaneous respiration after anesthesia and made possible a safe early extubation of patients before leaving the operating room. The authors also stressed that all patients, irrespective of their clinical conditions, must be transferred after thymectomy. Oto the surgical ICU where anticholinesterase therapy can be safely restarted and cardiorespiratory status carefully monitored.

    The technology of anesthesia ventilators has substantially progressed during last years. The choice of a pediatric anesthesia ventilator needs to be led by multiple parameters: requirement, technical (pneumatic performance, velocity of halogenated or oxygen delivery), cost (purchase, in operation, preventive and curative maintenance), reliability, ergonomy, upgradability, and compatibility. The demonstration of the interest of pressure support mode during maintenance of spontaneous ventilation anesthesia makes this mode essential in pediatrics. In contrast, the financial impact of target controlled inhalation of halogenated has not be studied in pediatrics. Paradoxically, complex and various available technologies had not been much prospectively studied. Anesthesia ventilators performances in pediatrics need to be clarified in further clinical and bench test studies.

    A Baird's tapir (Tapirus bairdii) was satisfactorily immobilized on two occasions with i.m. detomidine (0.065-0.13 mg/kg) and butorphanol (0.13-0.2 mg/kg). On the second occasion, anesthesia was induced by i.v. administration of ketamine (2.2 mg/kg). Twenty minutes later, endotracheal intubation was performed after an additional i.v. injection of ketamine (1.5 mg/kg). Anesthesia was maintained with isoflurane, which provided excellent conditions for radiology and surgery. Anesthesia was associated with hypoxemia when the tapir was allowed to breathe air and with hypoventilation. Mean arterial pressure remained satisfactory. No antagonist drugs were administered, and recovery from anesthesia was rapid and smooth.

    Weng, Meilin; Chen, Wankun; Hou, Wenting; Li, Lihong; Ding, Ming; Miao, Changhong

    2016-01-01

    Several animal and observational studies have evaluated the effects of neuraxial anesthesia on the recurrence and survival of cancer surgery; studies reported benefit, whereas others did not. To provide further evidence that neuraxial anesthesia(combined with or without general anesthesia (GA))may be associated with reduced cancer recurrence and long-term survival after cancer surgery, we conducted this meta-analysis. A total of 21 studies were identified and analyzed, based on searches conducted using PubMed, Web of Science, EMBASE database and the Cochrane Database of Systematic Reviews. After data abstraction, adjusted hazard ratios (HR) with 95% confidence intervals (CIs) were used to assess the impact of neuraxial anesthesia (combined with or without GA) and GA on oncological outcomes after cancer surgery. For overall survival (OS), a potential association between neuraxial anesthesia and improved OS (HR 0.853, CI 0.741-0.981, P = 0.026, the random-effects model) was observed compared with GA. Specifically, we found a positive association between neuraxial anesthesia and improved OS in colorectal cancer (HR 0.653, CI 0.430-0.991, P = 0.045, the random-effects model). For recurrence-free survival (RFS), a significant association between neuraxial anesthesia and improved RFS (HR 0.846, CI 0.718-0.998, P = 0.047, the random-effects model) was detected compared with GA. Our meta-analysis suggests that neuraxial anesthesia may be associated with improved OS in patients with cancer surgery, especially for those patients with colorectal cancer. It also supports a potential association between neuraxial anesthesia and a reduced risk of cancer recurrence. More prospective studies are needed to elucidate whether the association between neuraxial use and survival is causative. PMID:26918830

    2013-03-01

    Full Text Available Introduction: We have analyzed our initial results of our anesthesia techniques in our new-onset endovascular aortic reconstruction cases.Patients and Methods: The perioperative data of 15 elective and emergent endovascular aortic reconstruction cases that were operated in 2010-2011 were collected in a database. The choice of anesthesia was made by the risk factors, surgical team’s preferences, type and location of the aortic pathology and by the predicted operation duration. The data of local and general anesthesia cases were compared.Results: Thirteen (86.7% cases were male and 2 (13.3% female. Eleven patients were in ASA Class III. The demographic parameters, ASA classifications, concurrent diseases were similar in both groups. Thirteen (86.7% cases had infrarenal abdominal aortic aneurysm and 2 (13.3% had Type III aortic dissection. The diastolic arterial pressures were lower in general anesthesia group in 20th and 40th minutes’ measurements just like the mean arterial pressure measurements at the 40th, 100th minutes and during the deployment of the graft. Postoperative mortality occurred in 3 (20.0% patients and they all had general anesthesia and they were operated on emergency basis. Postoperative morbidity occurred in four patients that had general anesthesia (acute renal failure, multi-organ failure and pneumonia. The other patient had atrial fibrillation on the 1st postoperative day and was converted to sinus rhythm with amiodarone infusion.Conclusion: Edovascular aortic reconstruction procedures can safely be performed with both general and local anesthesia less invasively compared to open surgery. General anesthesia may be preferred for the better hemodynamic control.

    2013-03-01

    In spaceflight beyond low Earth's orbit, medical conditions requiring surgery are of a high level of concern because of their potential impact on crew health and mission success. Whereas surgical techniques have been thoroughly studied in spaceflight analogues, the research focusing on anesthesia is limited. To provide safe anesthesia during an exploration mission will be a highly challenging task. The research objective is thus to describe specific anesthesia procedures enabling treatment of pre-identified surgical conditions. Among the medical conditions considered by the NASA Human Research Program Exploration Medical Capability element, those potentially necessitating anesthesia techniques have been identified. The most appropriate procedure for each condition is thoroughly discussed. The substantial cost of training time necessary to implement regional anesthesia is pointed out. Within general anesthetics, ketamine combines the unique advantages of preservation of cardiovascular stability, the protective airway reflexes, and spontaneous ventilation. Ketamine side effects have for decades tempered enthusiasm for its use, but recent developments in mitigation means broadened its indications. The extensive experience gathered in remote environments, with minimal equipment and occasionally by insufficiently trained care providers, confirms its high degree of safety. Two ketamine-based anesthesia protocols are described with their corresponding indications. They have been designed taking into account the physiological changes occurring in microgravity and the specific constraints of exploration missions. This investigation could not only improve surgical care during long-duration spaceflights, but may find a number of terrestrial applications in isolated or austere environments.

Objective: to evaluate the efficacy of epidural anesthesia in repetitive cesarean. Methods: a descriptive retrospective study of a series of cases (112in which epidural anesthesia in repetitive cesarean was applied from January 2001 to December 2001 in the surgical unit of the Gynecological obstetric service at the University Hospital ¨Dr. Gustavo Aldereguía Lima¨ in Cienfuegos city, Cuba. Some variables such as fixation time of the anesthesia, its duration, transurgical and postsurgical hemodynamic behavior, complications related with the anesthesia, evaluation of the new born baby and, the level of satisfaction of the patients were analyzed. Results: The immediate transurgical and postsurgical hemodynamic behavior was stable predominating normotension and the normal cardiac frequency. The complications related to anesthesia were minimal. The level of satisfaction of the patients was elevated. No alterations in new born babies were presented. As a conclusion, it may be stated that epidural anesthesia in repetitive cesarean is a safety and reliable anesthetic method.

Materials and Methods: After institutional review board approval, a questionnaire was uploaded on SurveyMonkey and sent to anesthesia providers through their program coordinators in United States (US to complete the survey. Results: The current US national total-population sex ratio is 0.97 male (s/female with an at-birth sex ratio of 1.05 male (s/female; comparatively, the results from anesthesia providers′ survey respondents (n = 314 were a total OSR of 0.93 male (s/female ( P = 0.61 with firstborn OSR 0.82 male (s/female (a 6% increase in female offspring; P = 0.03, respectively. The only significant peri-conceptional factor related to anesthesia providers′ firstborn OSR′s skew was inhalational induction practice by anesthesia care provider favoring female offspring ( P < 0.01. Conclusion: Based on the results of this limited survey, it can be concluded that anesthesia care providers who practice inhalation induction of anesthesia during the peri-conceptional period are significantly more likely to have firstborn female offspring.

    Recently, some scholars suggested that it is important to keep a stablehemodynamic state and prevent the stress responses in geriatric patients undergoing total hip replacement (THR). We conducted this randomized prospective study to observe anesthetic potency of unilateral spinal anesthesia and stress response to it in geriatric patients during THR. We compared the effect of unilateral spinal and bilateral spinal on inhibition of stress response through measuring Norepinephrine (NE), epinephrine (E) and cortisol (CORT). Plasma concentrations of NE, E and CORT were determined in blood samples using ELISA (enzyme-linked immunosorbent assays) at three time points: To (prior to anesthesia) T1 (at the time point of skin closure), T2 (twenty-four hours after the operation). Sixty patients were randomly divided into two groups: group A (unilateral spinal anesthesia) and group B (conventional bilateral spinal anesthesia). 7.5tymg of hypobaric bupivacaine were injected into subarachnoid cavity at group A and 12mg hypobaric bupivacaine were given at group B. The onset time of sensory and motor block, loss of pinprick sensation, degree of motor block, regression of sensory and motor blocks and hemodynamic changes were also recorded. These data were used to evaluate anesthetic potency of spinal anesthesia. The results of this experiment show that unilateral spinal anesthesia can provide restriction of sensory and motor block, minimize the incidence of hypotension and prevent the stress responses undergoing THR. It is optimal anesthesia procedure for geriatric patients by rapid subarachnoid injection of small doses of bupivacaine.

    Tracheal intubation general anesthesia technique is widely used in video-assisted thoracic surgery (VATS) because it can improve the safety of VATS, but the complications of tracheal intubation can not be avoided. How to develop a "minimally invasive" surgery (including micro anesthesia) has become a hot topic in the field of minimally invasive surgery. Along with the progress of the anesthesia management technology and the risk management in the operation, the technology of non-intubated anesthesia was successfully applied to VATS, namely using local anesthesia to maintain patients intraoperative independent ventilation and intraoperative only mild sedation or fully conscious state of implementation of thoracoscope surgery, therefore is also called awake VATS. The anesthesia method not only reduces the anesthesia injury of tracheal intubation, but also conforms to the idea of rapid rehabilitation surgery. Based on non-intubated anesthesia in VATS in the brief history of development, the anesthesia selection, operation advantages and risks are reviewed in this paper.

    Purpose: To assess pain intensity with and without subcutaneous local anesthesia prior to intraarticular administration of contrast medium for magnetic resonance arthrography (MRa) of the shoulder. Materials and methods: This single-center study was conducted after an IRB waiver of authorization, between January 2010 and December 2012. All patients provided written, informed consent for the procedure. Our prospectively populated institutional database was searched, based on our inclusion criteria. There were 249 outpatients (178 men and 71 women; mean age, 44.4 years ± 14.6; range, 15–79) who underwent MRa and were enrolled in this study. Patients were excluded if they had received surgery of the shoulder before MRa, had undergone repeated MRa of the same shoulder, and/or had undergone MRa of both shoulders on the same day. Patients were randomly assigned into one of three groups. Patients in group A (n = 61) received skin infiltration with local anesthesia. Patients in control group B (n = 92) and group C (n = 96) did not receive local anesthesia. Pain levels were immediately assessed after the injection for MRa using a horizontal visual analog scale (VAS) that ranged from 0 to 10. To compare the pain scores of the three groups for male and female patients, a two-way analysis of variance was used. A p-value equal to or less than 0.05 was considered to indicate a significant result. Results: Patients who received local anesthesia (group A) showed a mean pain level on the VAS of 2.6 ± 2.3. In patients who did not receive local anesthetics (groups B and C), a mean pain level on the VAS of 2.6 ± 2.2 and 2.7 ± 2.4 were detected, respectively. Between the three groups, no statistically significant difference in pain intensity was detected (p = .960). There were significant differences in subjective pain perception between men and women (p = .009). Moreover, the sex difference in all three groups was equal (p = .934). Conclusion: Local anesthesia is not required to

    Purpose: To evaluate the feasibility, reliability and analgesia effect of topical anesthesia combined with subconjunctival anesthesia in anti-glaucomatous surgery.Methods: Two hundred and four cases (357 eyes) underwent anti-glaucomatous surgeries under topical anesthesia with 0.5% Alcaine eye drops combined with subconjunctival anesthesia with 2% Lidocaine. The analgesic effect was analysed with visual analogue pain scale.Results: Among all of 357 eyes, 62 eyes underwent peripheral iridectomy, 67 eyes underwent simple trabeculectomy, 167 eyes underwent compound brabeculectomy and 12 eyes nonpenetrating trabecular surgery. The effects of anesthesia were as follows: 304 eyes(85.2%) were painless (Grade I ), 50 eyes (14.0%) were slight painful (Grade Ⅱ ), and 3 eyes (0.8%) were more painful (Grade Ⅲ ) during surgery. And no severe complications were observed in all the cases during surgery and postoperatively. Amaurosis fugax was not observed in the glaucoma patients at the late stage with narrow visual fields and poor visual ability.Conclusion: Topical anesthesia combined with subconjunctival anesthesia is effective,safe and simple anesthesia alternative in routine anti-glaucomatous surgery, especially for the glaucoma patients at the late stage with narrow visual fields and poor visual ability. It is worthy of being applied widely.

    Full Text Available CONTEXT AND OBJECTIVE: As the rates of cesarean births have increased, the type of cesarean anesthesia has gained importance. Here, we aimed to compare the effects of general and spinal anesthesia on maternal and fetal outcomes in term singleton cases undergoing elective cesarean section.DESIGN AND SETTING: Prospective randomized controlled clinical trial in a tertiary-level public hospital.METHODS: Our study was conducted on 100 patients who underwent cesarean section due to elective indications. The patients were randomly divided into general anesthesia (n = 50 and spinal anesthesia (n = 50 groups. The maternal pre and postoperative hematological results, intra and postoperative hemodynamic parameters and perinatal results were compared between the groups.RESULTS: Mean bowel sounds (P = 0.036 and gas discharge time (P = 0.049 were significantly greater and 24th hour hemoglobin difference values (P = 0.001 were higher in the general anesthesia group. The mean hematocrit and hemoglobin values at the 24th hour (P = 0.004 and P < 0.001, respectively, urine volume at the first postoperative hour (P < 0.001 and median Apgar score at the first minute (P < 0.0005 were significantly higher, and the time that elapsed until the first requirement for analgesia was significantly longer (P = 0.042, in the spinal anesthesia group.CONCLUSION: In elective cases, spinal anesthesia is superior to general anesthesia in terms of postoperative comfort. In pregnancies with a risk of fetal distress, it would be appropriate to prefer spinal anesthesia by taking the first minute Apgar score into account.

    Full Text Available Background: Anesthesia is a specialized branch of medicine with a very narrow margin of error. Incorporation of problem-based learning (PBL in anesthesia post-graduate (PG teaching enhances the critical thinking and problem-solving skills. It also helps in developing a broader prospective of clinical case scenarios. Case based discussions (CBD are most widely practiced out of all PBL methods in anesthesia PG teaching. Materials and Methods: We conducted an anonymous questionnaire based, cross-sectional survey among 62 anesthesia residents from various medical institutions in a city of Delhi, India. We aimed to assess the current status of PBL by assessing the student satisfaction with CBD in anesthesia PG teaching, educational objectives accomplished with CBD and effectiveness of teaching curriculum in PG teaching with suggested modifications, if any. Result and Conclusion: We observed that CBD is lacking in many important key areas of PBL e.g., formulation of objectives, communication on the content and direction of PBL, facilitation skills, supplementation of inadequacies of CBD. However, CBD seems to be a valid method of PBL in terms of the educational objectives accomplished with it but increased motivation for learning is required. Majority of the students felt that PG teaching curriculum should be centralized, with increased emphasis on open interactive sessions regarding its effectiveness.

    Background: Spinal anesthesia is a preferred technique over general anesthesia for cesarean delivery. It avoids maternal airway related complications, aspiration and neonatal depression. However hypotension following spinal anesthesia can lead to decrease in uterine blood flow and neonatal hypoxia. Aims: We aimed to evaluate the efficacy of 15 mL.kg- 1of crystalloid preloading versus prophylactic intravenous bolus of 10 mg ephedrine as an antihypotensive measure for cesarean section. Methods: A prospective randomized double blind study was conducted in hundred ASA grade I/II parturient undergoing cesarean section, allocated to group P (n=50) who received preloading with ringer lactate 15 mL.kg- 1 over 20 minutes before spinal anesthesia and group E (n=50) received intravenous bolus of 10mg ephedrine within one minute of spinal anesthesia with 10mg of hyperbaric bupivacaine 0.5% at L2-3/L3-4 level. They were monitored for incidences of hypotension, need of rescue doses of ephedrine, Apgar score and adverse events. Appropriate statistical tests were applied and P Apgar score were better in group E than in group P delivered babies. Conclusion: Prophylactic intravenous bolus of 10mg ephedrine with spinal injection is more effective in maintaining maternal hemodynamic stability and better neonatal outcome as compared to crystalloid preloading during cesarean delivery.

Methods: Regional anesthesia fellowship directors across the world were asked to complete a comprehensive survey that detailed the range of educational and practical experience and attitudes as well as assessment procedures offered in their programs. Results: The survey response rate was 66% (45/68. Overall, the range of activities and the time and resources committed to education during fellowships is encouraging. A wide range of nerve block experience is reported with most programs also offering acute pain management, research, and teaching opportunities. Only two-thirds of fellowships provide formal feedback. This feedback is typically a formative assessment. Conclusion: This is the first survey of regional anesthesia fellowship directors, and it illustrates the international scope and continuing expansion of education and training in the field. The results should be of interest to program directors seeking to benchmark and improve their educational programs and to faculty involved in further curriculum development.

    Twenty-two cases of Cesarean section due to fetal anomaly diagnosed prenatally were reviewed in terms of the anesthetic managements. In 6 cases, diazepam 0.3 mg.kg-1, which provides fetal anesthesia for surgery scheduled immediately after birth, was administered intravenously to the mothers with/without fentanyl (2 general anesthesia and 4 regional anesthesia). The diagnosis of their fetuses was congenital diaphragmatic hernia, congenital cystic adenomatoid malformation of the lung, gastroschisis or omphalocele. No fetal anesthesia was performed in the other 16 cases (15 spinal anesthesia and 1 general anesthesia). Seven of their fetuses were diagnosed as hydrops. Since the general condition of the diseased newborn is known to be deteriorated after receiving various stress and aerophagia, fetal anesthesia in Cesarean delivery has the advantage of stress reduction and prevention of aerophagia. When the newborn is considered to need immediate neonatal resuscitation or intensive care including surgery, fetal anesthesia may be a choice of anesthetic technique.

    Full Text Available Lidocaine has been used for more than 50 years for spinal anesthesia and has a remarkable safety record. In 1993, a new adverse effect, transient neurologic toxicity was described in patients recovering from spinal anesthesia with lidocaine. Transient neurological symptoms have been defined as pain in the lower extremities (buttocks, thighs and legs after an uncomplicated spinal anesthesia and after an initial full recovery during the immediate postoperative period (less than 24 h. The incidence of transient neurological symptoms reported in prospective, randomized trials varies from 4% to 37%. The etiology of transient neurological symptoms remains unkonwn. Despite the transient nature of this syndrome, it has proven to be difficult to treat effectively. Drug or some interventional therapy may be necessary.

    Deep isoflurane anesthesia initiates a burst suppression pattern in which high-amplitude bursts are preceded by periods of nearly silent electroencephalogram. The burst suppression ratio (BSR) is the percentage of suppression (silent electroencephalogram) during the burst suppression pattern and is one parameter used to assess anesthesia depth. We investigated cortical burst activity in rats in response to different auditory stimuli presented during the burst suppression state. We noted a rapid appearance of bursts and a significant decrease in the BSR during stimulation. The BSR changes were distinctive for the different stimuli applied, and the BSR decreased significantly more when stimulated with a voice familiar to the rat as compared with an unfamiliar voice. These results show that the cortex can show differential sensory responses during deep isoflurane anesthesia.

    Full Text Available Introduction & Objective: The efficacy of Percutaneous Nephrolithotomy (PCNL in the treatment of renal stones has been proven in its indications. The main method of anesthesia in this procedure is general anesthesia. We used spinal anesthesia (SA as an alternative method of anesthesia with many benefits. This study was intended to show the possibility of SA as a more comfortable method of anesthesia for the surgeon , the anesthesiologist and the patient via more cooperation of the patient during changing the position and prevention of some complications mostly in upper extremities and neck. Materials & Methods: In a prospective clinical trial study, a total of 112 patients underwent PCNL under SA with marcaine , from Nov 2004 till Feb 2009. Their mean age was 36 years (22-48, at first the syringe was stained by epinephrine and then 2 -3.5 ml marcaine was used for SA and addition of analgesics , sedatives or both., if needed. The rest of the procedure was done as routine.Results: Stone clearance was achieved in 82% of the patients and the rest were managed by ESWL. The mean operation time was 126 minutes (90-220, 36% of the patients needed sedation, analgesia, or both, specially those with bigger stones. 6% of the patients had upper pole stones .Blood transfusion was needed only in one patient. No significant complication was observed in this study.Conclusion: PCNL under SA afforded the surgeon and the anesthesiologist the opportunity of more patient cooperation during position changes and precludes some morbidities that may happen under general anesthesia because the patient is awake and able to portend.

    2011-01-01

    Background: Bacterial contamination of anesthesia breathing machines and their potential hazard for pulmonary infection and cross-infection among anesthetized patients has been an infection control issue since the 1950s. Disposable equipment and bacterial filters have been introduced to minimize this risk. However, the machines’ internal breathing-circuit-system has been considered to be free of micro-organisms without providing adequate data supporting this view. The aim of the study was to investigate if any micro-organisms can be yielded from used internal machines’ breathing-circuit-system. Based on such results objective reprocessing intervals could be defined. Methods: The internal parts of 40 anesthesia machines’ breathing-circuit-system were investigated. Chi-square test and logistic regression analysis were performed. An on-site process observation of the re-processing sequence was conducted. Results: Bacterial growth was found in 17 of 40 machines (43%). No significant difference was ascertained between the contamination and the processing intervals. The most common contaminants retrieved were coagulase negative Staphylococci, aerobe spore forming bacteria and Micrococcus species. In one breathing-circuit-system, Escherichia coli, and in one further Staphylococcus aureus were yielded. Conclusion: Considering the availability of bacterial filters installed on the outlet of the breathing-circuit-systems, the type of bacteria retrieved and the on-site process observation, we conclude that the contamination found is best explained by a lack of adherence to hygienic measures during and after re-processing of the internal breathing-circuit-system. These results support an extension of the re-processing interval of the anesthesia apparatus longer than the manufacturer’s recommendation of one week. However, the importance of adherence to standard hygienic measures during re-processing needs to be emphasized. PMID:22242095

    The professional singer comes to the day of surgery with a measure of anxiety about the effects of anesthesia or surgery on his or her voice. A detailed informed consent should be obtained to discuss and document risks, as well as set realistic expectations for recovery. The smallest endotracheal tube possible should be used to intubate in the least traumatic way. Movement of the tube should be minimized, both during anesthesia, as well as in emergence. Postoperative care may be coordinated with an otolaryngologist and speech language pathologist as the singer plans a return to performance.

    Full Text Available Context: Spinal anesthesia (SA was combined with general anesthesia (GA for achieving hemodynamic stability in laparoscopic hysterectomy. Aims: The aim of our study was to evaluate the impact of SA combined with GA in maintaining hemodynamic stability in laparoscopic hysterectomy. The secondary outcomes studied were requirement of inhaled anesthetics, vasodilators, and recovery profile. Settings and Design: We conducted a prospective, randomized study in ASAI/II patients posted for laparoscopic hysterectomy, who were willing to participate in the study. Materials and Methods: Patients were randomly assigned to receive SA with GA (group SGA or plain GA (group GA. Group SGA received 10 mg bupivacaine (heavy for SA. GA was administered using conventional balanced technique. Maintenance was carried out with nitrous oxide, oxygen, and isoflurane. Comparison of hemodynamic parameters was carried out during creation of pneumoperitoneum and thereafter. Total isoflurane requirement, need of vasodilators, recovery profile, and regression of SA were studied. Statistical analysis used: Descriptive statistics in the form of mean, standard deviation, frequency, and percentages were calculated for interval and categorical variables, respectively. One-way analysis of variance (ANOVA was applied for noting significant difference between the two groups, with chi-square tests for categorical variables and post-hoc Bonferroni test for interval variables. Comparison of heart rate (HR, mean arterial pressure (MAP, SPO2, and etCO2 was done with Student′s t-test or Mann-Whitney test, wherever applicable. Results: Patients in group SGA maintained stable and acceptable MAP values throughout pneumoperitoneum. The difference as compared to group GA was statistically significant (P < 0.01. Group GA showed additional requirement of metoprolol (53.33% and higher concentration of isoflurane (P < 0.001 to combat the increased MAP. Recovery was early and quick in group SGA as

    Conclusion: Awareness under anesthesia is a distressing complication with a potential for long-term psychological consequences, and every effort should be undertaken to prevent it. It is reassuring though that our data in Indian cancer patients at high risk for intra-operative awareness suggests that it is an uncommon occurrence.

    Thoracoscopy has been recently established as an indispensable technique for diagnosis and treatment of respiratory diseases. Although, thoracoscopy is usually applied under general anesthesia by a surgeon, it can also be applied by a chest physician under local anesthesia if the target is limited to pleural diseases. The main objective of medical thoracoscopy under local anesthesia is to establish a diagnosis of pleural effusions by means of observation and biopsy in the thoracic cavity. Our main target diseases are the pleuritis carcinomatosa, malignant mesothelioma and tuberculous pleuritis. These 3 diseases are the diseases with which medical thoracoscopy is most useful because they can be reliably diagnosed by biopsies and because early diagnosis and early treatment are essential. In case of the pneumothorax, treatment with bulla looping or cauterization may be possible, but we do not treat pneumothorax with medical thoracoscopy because it is impossible to approach and find air leaks of lesions located in or near blind spots such as the apex or mediastinal part In case of acute emphysema, it is important to release adhesions and perform effective drainage using thoracoscopy as soon as possible since deposition of fibrin tends to form quickly compartments that make drainage difficult. Scince medical thoracoscopy under local anesthesia is rapid, easy, safe, and well-tolerated procedure with an excellent diagnostic yield, it is recommended as a diagnostic procedure for cases with pleural diseases.

    Full Text Available Objective: to evaluate the nature of unilateral spinal anesthesia using various modes of administration of low doses of hyperbaric bupivacaine. Materials and Methods. Prospectively, the randomized study included 56 patients undergoing knee arthroscopy. In the control group bupivacaine of 5mg was administered simultaneously, in the main group — fractionally by 2.5 mg. The development of thermal and pain blocks from different sides was investigated. The data were statistically processed. Results. In the control group, the positioning of the patient usually began after the entire dose of anesthetic had been administered. In the case of temperature paresthesia in the area of the sacral segments of the full anesthesia throughout underlying limb was not always achieved. In 6 cases of block was not sufficient. In the main group patient positioning was performed after the administration of 2.5 mg of anesthetic and evaluate temperature paresthesia and in 2 cases the total dose was increased to 7.5 mg. The successful development of sensory block at fractional administration was significantly higher than in the single-step introduction. Conclusion. Temperature paresthesia occurs within the first minute and is an early predictor of developing spinal anesthesia. The area of arising paresthesia shows preferential distribution of the anesthetic. In the application of low dose local anesthetic the desired upper level of anesthesia via the patient positioning and dose adjustment may be achieved.

    Aim: To report a series of varicocelectomy performed under pure local anesthesia. Methods: From July 1988 to June 2003, a total of 575 patients, aged between 15 and 73 years, underwent high ligation of the internal spermatic vein for treatment of a varicocele testis under a regional block in which a precise injection of 0.8 % lidocaine solution was delivered to involved tissues after exact anatomical references were made. A 100-mm visual analog scale (VAS)was used to assess whether the pain level was acceptable. Results: The surgeries were bilateral in 52 cases, and unilateral in 523 cases. All were successfully performed on an outpatient basis except in the case of two patients, who were hospitalized because their surgeries required general anesthesia. Overall, 98.6 % (567/575) of men could go back to work by the end of the first post-operative week and only 8 (1.4 %) men reported feeling physical discomfort on the eighth day. The VAS scores varied from 11 mm to 41 mm with an average of (18.5 ± 11.3) mm that was regarded as tolerable. Conclusion: This study has shown varicocelectomy under local anesthesia to be possible,simple, effective, reliable and reproducible, and a safe method with minimal complications. It offers the advantages of more privacy, lower morbidity, with no notable adverse effects resulting from anesthesia, and a more rapid return to regular physical activity with minor complications.

    O'Donnell, Brian D

    2012-02-03

    PURPOSE OF REVIEW: The purpose of this review is to present advances in the use of regional anesthetic techniques in ambulatory orthopedic surgery. New findings regarding the use of both neuraxial anesthesia and peripheral nerve block are discussed. RECENT FINDINGS: Neuraxial anesthesia: The use of short-acting local anesthetic agents such as mepivacaine, 2-chloroprocaine, and articaine permits rapid onset intrathecal anesthesia with early recovery profiles. Advantages and limitations of these agents are discussed.Peripheral nerve block: Peripheral nerve blocks in limb surgery have the potential to transform this patient cohort into a truly ambulatory, self-caring group. Recent trends and evidence regarding the benefits of regional anesthesia techniques are presented.Continuous perineural catheters permit extension of improved perioperative analgesia into the ambulatory home setting. The role and reported safety of continuous catheters are discussed. SUMMARY: In summary, shorter acting, neuraxial, local anesthetic agents, specific to the expected duration of surgery, may provide superior recovery profiles in the ambulatory setting. A trend towards more peripheral and selective nerve blocks exists. The infrapatellar block is a promising technique to provide analgesia following knee arthroscopy. Improved analgesia seen in the perioperative period can be safely and effectively extended to the postoperative period with the use of perineural catheters.

    Horner syndrome is rarely observed in connection with epidural anesthesia. It is characterized by ptosis, enophthalmos, miosis, anisocoria, and conjunctival hyperemia in the affected eye, as well as anhydrosis and flushing on the affected side of the face. It is usually a complication spontaneously resolved without permanent neurological deficits. Intraoral anesthesia; stellate ganglion, cervical or brachial plexus blocks; thoracic, lumbar or caudal epidural anesthesia, and intrapleural analgesia are the main causes for Horner syndrome related to anesthesia. Among other causes of Horner syndrome are head and neck surgery, trauma, and puncture of internal jugular vein. The present case of unilateral Horner syndrome appeared in the aortobifemoral bypass after lumbar spinal- epidural anesthesia.

Materials and Methods: Forty American Society of Anesthesiologists (ASA physical status I-II patients were randomly allocated into two groups and unilateral spinal anesthesia with low-dose levobupivacaine (group S, n=20 or CSFB (group B, n=20 was performed. Besides the quality of anesthesia, anesthetic effectiveness, hemodynamic values, duration of the technique application, maximum motor and sensorial block levels and durations, the first analgesics need, and total analgesic consumptions during postoperative 24 hours and determined complications were compared between the two groups. Results: The quality of anesthesia was better in group S, no patient received either sedation or analgesic intraoperatively while first analgesic need and number of patient was higher (p=0.014, p<0.001, p=0.032 respectively. The duration of technical application was shorter while maximum motor and sensorial block levels were higher in group S (p<0.0001, p=0.008, p<0.001 respectively. Motor block duration was significantly longer in group B (p<0.0001. Conclusion: We concluded that CSFB practice is an effective anesthetic alternative for unilateral spinal anesthesia. Introduction

  14. A Wavelet Transform Based Method to Determine Depth of Anesthesia to Prevent Awareness during General Anesthesia

    Full Text Available Awareness during general anesthesia for its serious psychological effects on patients and some juristically problems for anesthetists has been an important challenge during past decades. Monitoring depth of anesthesia is a fundamental solution to this problem. The induction of anesthesia alters frequency and mean of amplitudes of the electroencephalogram (EEG, and its phase couplings. We analyzed EEG changes for phase coupling between delta and alpha subbands using a new algorithm for depth of general anesthesia measurement based on complex wavelet transform (CWT in patients anesthetized by Propofol. Entropy and histogram of modulated signals were calculated by taking bispectral index (BIS values as reference. Entropies corresponding to different BIS intervals using Mann-Whitney U test showed that they had different continuous distributions. The results demonstrated that there is a phase coupling between 3 and 4 Hz in delta and 8-9 Hz in alpha subbands and these changes are shown better at the channel T7 of EEG. Moreover, when BIS values increase, the entropy value of modulated signal also increases and vice versa. In addition, measuring phase coupling between delta and alpha subbands of EEG signals through continuous CWT analysis reveals the depth of anesthesia level. As a result, awareness during anesthesia can be prevented.

    Neural plasticity changes within the olfactory bulb are important for olfactory learning, although how neural encoding changes support new associations with specific odors and whether they can be investigated under anesthesia, remain unclear. Using the social transmission of food preference olfactory learning paradigm in mice in conjunction with in vivo microdialysis sampling we have shown firstly that a learned preference for a scented food odor smelled on the breath of a demonstrator animal occurs under isofluorane anesthesia. Furthermore, subsequent exposure to this cued odor under anesthesia promotes the same pattern of increased release of glutamate and gamma-aminobutyric acid (GABA) in the olfactory bulb as previously found in conscious animals following olfactory learning, and evoked GABA release was positively correlated with the amount of scented food eaten. In a second experiment, multiarray (24 electrodes) electrophysiological recordings were made from olfactory bulb mitral cells under isofluorane anesthesia before, during and after a novel scented food odor was paired with carbon disulfide. Results showed significant increases in overall firing frequency to the cued-odor during and after learning and decreases in response to an uncued odor. Analysis of patterns of changes in individual neurons revealed that a substantial proportion (>50%) of them significantly changed their response profiles during and after learning with most of those previously inhibited becoming excited. A large number of cells exhibiting no response to the odors prior to learning were either excited or inhibited afterwards. With the uncued odor many previously responsive cells became unresponsive or inhibited. Learning associated changes only occurred in the posterior part of the olfactory bulb. Thus olfactory learning under anesthesia promotes extensive, but spatially distinct, changes in mitral cell networks to both cued and uncued odors as well as in evoked glutamate and GABA

    Abstract Currently, no reported studies have evaluated intraoperative handover among anesthesia providers. Studies on anesthetic handover in the US recovery room setting observed that handover processes are insufficient and, in many instances, significant intraoperative events are disregarded. An online survey tool was sent to anesthesia providers at US anesthesia residency programs nationwide (120 out of the 132 US programs encompassing around 4500 residents and their academic MDAs) and a smaller survey selection of CRNAs (10 institutions about 300 CRNAs in the metropolitan area of Detroit, MI, USA) to collect information on handover practices. The response rate to this survey (n = 216) was comprised of approximately 5% (n = 71) of the resident population in US anesthesia programs, 5% (n = 87) of MDAs , and 20% (n = 58) of the CRNAs. Out of all respondents (n = 212), 49.1 % had no hand-over protocol at their institution and 88% of respondents who did have institutional handover protocols believed them insufficient for effective patient handover. In addiiton, 84.8% of all responders reported situations where there was insufficient information received during a patient handover. Only 7% of the respondents reported never experiencing complications or mismanagement due to poor or incomplete hand-overs. In contrast, 60% reported rarely having complications, 31% reported sometimes having complications, and 3% reported frequent complications. In conclusion, handover transition of patient care is a vulnerable and potentially life-threatening event in the operating room. Our preliminary study suggests that current intraoperatvive handover practices among anesthesia providers are suboptimal and that national patient handover guidelines are required to improve patient safety.

    There has been an increasing tendency for anesthesiologists to be responsible for providing sedation or anesthesia during chest CT imaging in young children. Anesthesia-related atelectasis noted on chest CT imaging has proven to be a common and troublesome problem, affecting image quality and diagnostic sensitivity. To evaluate the safety and effectiveness of a standardized anesthesia, lung recruitment, controlled-ventilation technique developed at our institution to prevent atelectasis for chest CT imaging in young children. Fifty-six chest CT scans were obtained in 42 children using a research-based intubation, lung recruitment and controlled-ventilation CT scanning protocol. These studies were compared with 70 non-protocolized chest CT scans under anesthesia taken from 18 of the same children, who were tested at different times, without the specific lung recruitment and controlled-ventilation technique. Two radiology readers scored all inspiratory chest CT scans for overall CT quality and atelectasis. Detailed cardiorespiratory parameters were evaluated at baseline, and during recruitment and inspiratory imaging on 21 controlled-ventilation cases and 8 control cases. Significant differences were noted between groups for both quality and atelectasis scores with optimal scoring demonstrated in the controlled-ventilation cases where 70% were rated very good to excellent quality scans compared with only 24% of non-protocol cases. There was no or minimal atelectasis in 48% of the controlled ventilation cases compared to 51% of non-protocol cases with segmental, multisegmental or lobar atelectasis present. No significant difference in cardiorespiratory parameters was found between controlled ventilation and other chest CT cases and no procedure-related adverse events occurred. Controlled-ventilation infant CT scanning under general anesthesia, utilizing intubation and recruitment maneuvers followed by chest CT scans, appears to be a safe and effective method to obtain

    General descriptions or "snapshots" of sedation/general anesthesia practices during dental care are very limited in reviewed literature. The objective of this study was to determine commonalities in dental sedation/anesthesia practices, as well as to accumulate subjective information pertaining to sedation/anesthesia care within the dental profession. This questionnaire-based survey was completed by participating anesthesia providers in the United States. A standardized questionnaire was sent via facsimile, or was delivered by mail, to 1500 anesthesia providers from a randomized list using an online database. Data from the returned questionnaires were entered onto an Excel spreadsheet and were imported into a JMP Statistical Discovery Software program for analyses. Quantitative evaluations were confined to summation of variables, an estimation of means, and a valid percent for identified variables. A total of 717 questionnaires were entered for data analysis (N=717). Data from this study demonstrate the wide variation that exists in sedation/anesthesia care and those providing its administration during dental treatment in the United States. The demographics of this randomized population show anesthesia providers involved in all disciplines of the dental profession, as well as significant variation in the types of modalities used for sedation/anesthesia care. Data from this study reveal wide variation in sedation/anesthesia care during dental treatment. These distinctions include representation of sedation/anesthesia providers across all disciplines of the dental profession, as well as variations in the techniques used for sedation/anesthesia care.

    BACKGROUND: Cognitive dysfunction occurs in elderly patients following general anesthesia, and this might be associated with genetics. Studies have shown that theε4 allele gene is closely associated with senile dementia.OBJECTIVE: To compare and analyze the correlations between cognitive dysfunction and single nucleotide polymorphism of apolipoprotein E (ApoE) following inhaJation or intravenous anesthesia.DESIGN, TIME AND SETTING: A randomized, controlled study was performed. The patients were recruited from the Department of Anesthesia, Second Affiliated Hospital, Medical College, Xi'an Jiaotong University, China between May 2005 and December 2008. Genetic analyses were conducted at the Departments of Neuroanatomy and Forensic Medicine, Medical College, Xi'an Jiaotong University, China.PARTICIPANTS: A total of 1 000 patients of ASA Ⅰ-Ⅱ grade, without genetic connection, were enrolled in this study, comprising 520 males and 480 females, aged (70.1±4.6) years and weighing (57.3±7.5) kg. No patients suffered from cognitive dysfunction.METHODS: The patients were equally and randomly divided into intravenous anesthesia and gas anesthesia groups. Total intravenous anesthesia and inhaled anesthesia were used. Genomic DNA from whole blood was extracted. The ApoE gene was amplified by PCR. Restriction fragment length polymorphism of ApoE gene was analyzed. Cognitive function was evaluated by Mini-Mental State Examination (MMSE). Patients scoring 0.05).CONCLUSION: Results demonstrated a correlation between cognitive dysfunction and ApoE single nucleotide polymorphism in elderly patients after gas anesthesia. However, no relationship between cognitive dysfunction and ApoE single nucleotide polymorphism was determined in elderly patients following intravenous anesthesia. Therefore, elderly patients, especially those expressing the ApoEε4 gene, should be cautiously exposed to gas anesthesia.

  1. An educational intervention to promote self-management and professional socialization in graduate nurse anesthesia students

    Science.gov (United States)

    Maloy, Debra A.

    Traditionally, nurse anesthesia educators have utilized prior academic achievement to predict student success. However, research has indicated that prior academic achievement offers an inadequate assessment of student success in graduate healthcare programs with extensive clinical residencies. The educational literature has identified many non-cognitive factors, such as self-efficacy and locus of control, that may provide a more holistic prediction model of student success. An experimental study with pretest-posttest design and stratified random assignment was conducted to evaluate the effectiveness of an educational intervention to promote self-management, professional socialization, and academic achievement among first semester graduate nurse anesthesia students. Participants (N = 66) were demographically similar to the national graduate nurse anesthesia student body, though Hispanics and younger students were a little over-represented in the sample (56% female, 75.8% White, 15.2% Hispanic, 6% Other, 59% ≤ 30-years-old, 67% ≤ 3 years of ICU). The results showed that most graduate anesthesia students had strong self-management and professional socialization characteristics on admission. The results did not support the effectiveness of this educational intervention. Thus, ceiling effect may have accounted in part for statistically non-significant results regarding self-efficacy (p = .190, o2 = .03), locus of control (p = .137, o2 = .04), professional socialization (p = .819, o2 = .001), and academic achievement (p = .689, o2 = .003). Future researchers may need to expand the scope of the intervention, use a more powerful and sensitive instrument, and utilize a larger sample.

    Full Text Available ABSTRACT OBJECTIVE: To evaluate the results and complications from surgical treatment of carpal tunnel syndrome by means of an open route, using a local anesthesia technique comprising use of a solution of lidocaine, epinephrine and sodium bicarbonate. MATERIAL AND METHODS: This was a cohort study conducted through evaluating the medical files of 16 patients who underwent open surgery to treat carpal tunnel syndrome, with use of local anesthesia consisting of 20 mL of 1% lidocaine, adrenaline at 1:100,000 and 2 mL of sodium bicarbonate. The DASH scores before the operation and six months after the operation were evaluated. Comparisons were made regarding the intensity of pain at the time of applying the anesthetic and during the surgical procedure, and in relation to other types of procedure. RESULTS: The DASH score improved from 65.17 to 16.53 six months after the operation (p < 0.01. In relation to the anesthesia, 75% of the patients reported that this technique was better than or the same as venous puncture and 81% reported that it was better than a dental procedure. Intraoperative pain occurred in two cases. There were no occurrences of ischemia. CONCLUSION: Use of local anesthesia for surgically treating carpal tunnel syndrome is effective for performing the procedure and for the final result.

    Boynes, Sean G; Echeverria, Zydnia; Abdulwahab, Mohammad

    2010-10-01

    The most widely used method for controlling pain during dental procedures is the intraoral administration of local anesthetics in close proximity to a specific nerve or fiber to obtund nerve conduction. The most commonly anesthetized nerves in dentistry are branches or nerve trunks associated with the maxillary and mandibular divisions of the trigeminal nerve (cranial nerve V). However, other nerves may be inadvertently affected by intraoral local anesthesia injections, resulting in anesthetic complications of structures far from the oral cavity. Practitioners should be aware of potential ocular complications following intraoral injections in dentistry. These complications include oculomotor paralysis and vision loss. The knowledge of these conditions and their potential cause should alert the dentist to the importance of appropriate injection techniques and an understanding of management protocol.

The study variables were pain intensity, assessed by visual analog scale, analgesic requirements until hospital discharge, time to ambulation and discharge, postoperative complications-related to both techniques and satisfaction experienced. Results: Thirty-two patients were enrolled; 16 patients in each group. The differences regarding pain were statistically significant at 2 h of admission (P < 0.001 and at discharge (P < 0.001 in favor of the GA plus ilioinguinal block group. In addition in this group, analgesic requirements were lower than SA group (P < 0.001, with times of ambulation and discharge significantly shorter. The SA group had a higher tendency to develop complications and less satisfaction. Conclusion: General anesthesia plus IIB is better than SA regarding postoperative analgesia, time to mobilization and discharge, side-effect profile and satisfaction experienced by the patients.

    Magnesium, one of the essential elements in the human body, has numerous favorable effects that offer a variety of possibilities for its use in obstetric anesthesia and intensive care. Administered as a single intravenous bolus dose or a bolus followed by continuous infusion during surgery, magnesium attenuates stress response to endotracheal intubation, and reduces intraoperative anesthetic and postoperative analgesic requirements, while at the same time preserving favorable hemodynamics. Applied as part of an intrathecal or epidural anesthetic mixture, magnesium prolongs the duration of anesthesia and diminishes total postoperative analgesic consumption with no adverse maternal or neonatal effects. In obstetric intensive care, magnesium represents a first-choice medication in the treatment and prevention of eclamptic seizures. If used in recommended doses with close monitoring, magnesium is a safe and effective medication.

    2016-09-01

    Full Text Available Myotonic dystrophy is the most common myotonic syndrome causing abnormalities of the skeletal and smooth muscles as well as problems related to the cardiac, gastrointestinal and endocrine systems. In affected people, reduced functional residual capacity, vital capacity, and peak inspiratory pressure are observed within the respiratory system. As would be expected, anesthetic management of these patients is challenging for anesthesiologists. In addition, delayed recovery from anesthesia and cardiac and pulmonary complications may develop in the intraoperative and early postoperative periods due to sensitivity to sedatives, anesthetic agents, and neuromuscular blocking agents. Myotonic dystrophy can be performed with the use of appropriate anesthesia procedures as well as carefully communication between anesthesiologists and surgeons. In conclusion, myotonic dystrophy has variations, which makes it important to preoperatively determine specific surgical and anesthetic management strategies for each patient. In this article, we present a patient with myotonic dystrophy who underwent laparoscopic cholecystectomy surgery for symptomatic cholelithiasis and to discuss the relevant literature.

    Traumatic brain injury (TBI) represents a wide spectrum of disease and disease severity. Because the primary brain injury occurs before the patient enters the health care system, medical interventions seek principally to prevent secondary injury. Anesthesia teams that provide care for patients with TBI both in and out of the operating room should be aware of the specific therapies and needs of this unique and complex patient population.

    Cigarette smoke contains over 4000 substances, some of which are harmful to the smoker. Some constituents cause cardiovascular problems, increasing the blood pressure, heart rate, and the systemic vascular resistance. Some cause respiratory problems, interfering with oxygen uptake, transport, and delivery. Further, some interfere with respiratory function both during and after anesthesia. Some also interfere with drug metabolism. Various effects on muscle relaxants have been reported. Risk of...

    The Anesthesia Quality Institute (AQI) was chartered in 2008 by the American Society of Anesthesiologists to develop the National Anesthesia Clinical Outcomes Registry (NACOR). In this Technical Communication, we will describe how data enter NACOR, how they are authenticated, and how they are analyzed and reported. NACOR accepts case-level administrative, clinical, and quality capture data from voluntarily participating anesthesia practices and health care facilities in the United States. All data are transmitted to the AQI in summary electronic files generated by billing, quality capture, and electronic health care record software, typically on a monthly basis. All data elements are mapped to fields in the NACOR schema in accordance with a publicly available data dictionary. Incoming data are loaded into NACOR by AQI technologists and are subject to both manual and automated review to identify systematically missing elements, miscoding, and inadvertent corruption. Data are deidentified in compliance with Health Insurance Portability and Accountability Act regulations. The database server of AQI, which houses the NACOR database, is protected by 2 firewalls within the American Society of Anesthesiologists' network infrastructure; this system has not been breached. The NACOR Participant User File, a deidentified case-level dataset of information from NACOR, is available to researchers at participating institutions. NACOR architecture and the nature of the Participant User File include both strengths and weaknesses.

    The Louisiana State University Health Sciences Center Department of Anesthesiology performed an analysis of anesthesia practice and needs within the State of Louisiana. The State of Louisiana currently has approximately 300 practicing anesthesiologists (physicians), 700 certified registered nurse anesthetists (CRNAs), and does not currently utilize anesthesiologist assistants (AAs). Approximately 500,000 anesthesia encounters occur annually in Louisiana. Although there is a recognized critical shortage of anesthesiologists nationally, this document will focus mainly on the issue of mid-level providers of anesthesia services. The overwhelming majority of surgical and obstetric procedures is performed using the anesthesia care team approach both nationally and in the State of Louisiana. Within the anesthesia care team model, the practice of certified registered nurse anesthetists and anesthesiologist assistants are interchangeable, and both would meet the need for mid-level anesthesia providers in the State of Louisiana.

    Local anesthetic solutions frequently contain vasoconstrictors to increase the depth and/or duration of anesthesia. Generally, the duration of soft-tissue anesthesia exceeds that of pulpal anesthesia. Negative consequences of soft-tissue anesthesia include accidental lip and tongue biting as well as difficulty in eating, drinking, speaking, and smiling. A double-blind, randomized, multicenter, Phase 2 study tested the hypothesis that local injection of the vasodilator phentolamine mesylate would shorten the duration of soft-tissue anesthesia following routine dental procedures. Participants (122) received one or two cartridges of local anesthetic/vasoconstrictor prior to dental treatment. Immediately after treatment, 1.8 mL of study drug (containing 0.4 mg phentolamine mesylate or placebo) was injected per cartridge of local anesthetic used. The phentolamine was well-tolerated and reduced the median duration of soft-tissue anesthesia in the lip from 155 to 70 min (p < 0.0001).

    Propofol is a new intravenous anesthetic agent that provides smooth and rapid induction of anesthesia. A short elimination half-life guarantees rapid recovery. Since it has been reformulated as an emulsion in soya bean oil, anaphylactoid reactions are unlikely to occur. As compared to adults, there is very little experience with propofol in pediatric anesthesia. The aim of this study was to evaluate propofol as an induction agent in children with respect to cardiovascular and respiratory effects and to investigate the incidence of other side-effects. METHOD. In 25 ASA I children aged 3-12 years (6.4 +/- 2.7 SD) anesthesia was induced with a single dose of propofol, after standard premedication with atropine 0.01 mg/kg and Thalamonal 0.04 ml/kg. Anesthesia was maintained with halothane, nitrous oxide, and oxygen. Blood pressure (BP), heart rate (HR), and arterial oxygen saturation (SaO2) were measured before and each minute for 6 min after propofol administration. The incidence of side-effects during induction of anesthesia as well as during recovery and the postoperative period were recorded. RESULTS. Propofol 2.5 mg/kg produced rapid and smooth induction of anesthesia. Mean arterial pressure decreased after 1 min by 14.3% with a maximum of 16.8% after 3 min. HR was influenced differently by propofol; children with initially high HR had a decrease in HR, whereas in children with a low initial rate, HR increased transiently. After 1 min, no further changes occurred. Although no apnea was observed, respiration was shallow and depressed, as indicated by a decrease in SaO2. Two children complained of pain and 4 of discomfort at the site of the injection; 1 of these developed transient phlebitis.(ABSTRACT TRUNCATED AT 250 WORDS)

To date, no reports compare the efficacy of spinal anesthesia (SA with that of GA for laparoscopic hernia repairs. The purpose of this study was to compare the surgical outcome of TEP inguinal hernia repair performed when the patient was treated under SA with that performed under GA. Materials and methods: Between July 2015 and July 2016, 50 patients were prospectively randomized to either the GA TEP group (Group I or the SA TEP group (Group II. Propofol, fentanyl, rocuronium, sevoflurane, and tracheal intubation were used for GA. Hyperbaric bupivacaine (15 mg and fentanyl (10 µg were used for SA to achieve a sensorial level of T3. Intraoperative events related to SA, operative and anesthesia times, postoperative complications, and pain scores were recorded. Each patient was asked to evaluate the anesthetic technique by using a direct questionnaire filled in 3 months after the operation. Results: All the procedures were completed by the allocated method of anesthesia as there were no conversions from SA to GA. Pain was significantly less for 1 h (P<0.0001 and 4 h (P=0.002 after the procedure for the SA and GA groups, respectively. There was no difference between the two groups regarding complications, hospital stay, recovery, or surgery time. Generally, patients were more satisfied with SA than GA (P<0.020. Conclusion: TEP inguinal hernia repair can be safely performed under SA, and SA was associated with less postoperative pain, better recovery, and better

    Anesthesia services are increasingly being requested for gastrointestinal (GI) endoscopy procedures. The preparation of the patients is different from the traditional operating room practice. The responsibility to optimize comorbid conditions is also unclear. The anesthetic techniques are unique to the procedures, as are the likely events that require intervention by the anesthesia team. The postprocedure care is also unique. The future needs for anesthesia services in GI endoscopy suite are likely to expand with further developments of the technology.

    Objective: To study clinical effect and anesthetic method of acupuncture anesthesia combined with epidural administration of smadose of anesthetic for cholecystectomy. Methods: A total of 194 cases of cholecystectomy patients were randomly divided into acupuncture combined with epidural anesthesia group (group A, n=66), acupoint-skin electrical stimulation combined with epidural anesthesia group (group B, n = 63) and simple epidural anesthesia group (group C, n=65). Observations were conducted using single-bland method. Bilateral Neiguan (PC 6) and Zusanli (ST 36) were punctured and stimulated electrically in group A and only stimulated electrically via cutaneous electrodes in group B. Epidural anesthetic used was 1.5% Lidocaine and the anesthetic level was controlled to reach T4~11. Results: The class-I (excellent) rates of group A, B and C were 75.76%, 60.32% and 13.85% respectively, showing significant differences between group A and C and group B and C ( P < 0. 001 ). The initial dose, doses of every hour and every case of group A and B were lower than those of group C. The dose of every hour of group C was 36.23% and 3.75 % higher than group A and B respectively ( P < 0. 001 ), suggesting that acupuncture or acu-point-skin electrical stimulation could strengthen anesthetic effect and reduce the dose of epidural anesthetic. During operation, indexes of the life signs as HR, MAP, RR, TV, MV, SpO2 and ECG kept basically stable and all patients in group A passed surgical operation safely. Conclusion: Acupuncture or acupoint-skin electrical stimulation combined with epidural anesthesia can be used as one of the anesthetic methods for cholecystectomy.

    Acupuncture Anesthesia originated from the pain relief and pain prevention theory in acupuncture and moxibustion. This technique is a new exploration of anesthesiology and an original achievement of China, representing a landmark combination of Traditional Chinese Medicine (TCM) and Western medicine. Acupuncture Anesthesia was initiated in 1958, and, reflecting the historical background of China after the 1960s, the use of this technique widely spread throughout the country. Reaching other countries after 1971, Acupuncture Anesthesia made a significant impact, drawing attention from medical academia worldwide. Thus, Acupuncture Anesthesia has made a special contribution to the medical science of modern China.

    We experienced anesthesia care for two patients taking methylphenidate (Ritalin), which is a central nervous system stimulant of amphetamine analogues, usually administered for narcolepsy or refractory depression. The proper dose of methylphenidate is 20-60 mg per day. General anesthesia with epidural anesthesia was administered to both cases for total hip replacement. One patient could discontinue taking methylphenidate five days before the operation, but the other patient could not. Both cases needed more anesthetics than usual on induction, but very stable condition could be maintained during and after the operations. We consider that it is possible to perform general anesthesia safely for patients taking a usual dose of methylphenidate.

    It has been reported that the action of infiltration anesthesia on the jawbone is attenuated significantly by elevation of the periosteal flap with saline irrigation in clinical studies; however, the reason is unclear. Therefore, the lidocaine concentration in mandibular bone after subperiosteal infiltration anesthesia was measured under several surgical conditions. The subjects were 48 rabbits. Infiltration anesthesia by 0.5 mL of 2% lidocaine with 1 : 80,000 epinephrine (adrenaline) was injected into the right mandibular angle and left mandibular body, respectively. Under several surgical conditions (presence or absence of periosteal flap, and presence or absence of saline irrigation), both mandibular bone samples were removed at a fixed time after subperiosteal infiltration anesthesia. The lidocaine concentration in each mandibular bone sample was measured by high-performance liquid chromatography. As a result, elevation of the periosteal flap with saline irrigation significantly decreased the lidocaine concentration in the mandibular bone. It is suggested that the anesthetic in the bone was washed out by saline irrigation. Therefore, supplemental conduction and/or general anesthesia should be utilized for long operations that include elevation of the periosteal flap with saline irrigation.

    Total knee arthroplasty performed under spinal or general anesthesia is a common successful orthopedic procedure. Nonetheless, in patients with diabetes mellitus this procedure can present unique challenges to orthopedic surgeon and anesthesiologist alike. We describe a case of an elderly male diabetic patient who developed bilaterally symmetrical lower limb neurological deficit following an uneventful total knee arthroplasty performed under spinal anesthesia. Postoperative nerve conduction study with electromyography confirmed symmetrical extensive denervation of lower limb muscles, including low-voltage fibrillation potentials and positive sharp waves. These findings were consistent with a preexisting neuropathy, thereby suggesting a subclinical neuropathy as a potential risk factor for this neurological complication. Our case highlights the fact that patients with longstanding comorbidities, namely peripheral vascular disease and diabetes mellitus, may be at an increased risk of neurological injury following regional anesthesia. Hence, we believe that preoperative evaluation of diabetic patients should include neurophysiological studies to identify subclinical neuropathy and minimize the risk of neurological injury.

    Full Text Available Background: Because of airway stimulations during the bronchoscopy and lack of direct access to the airway, preferred method of anesthesia for rigid bronchoscopy is already controversial. In this study we compared inhalation anesthesia with total intravenous anesthesia (TIVA for rigid bronchoscopy. Method and Materials: 30 patients aged 2-6 years were chosen divided on two same groups. Anesthesia in group I maintained with halothane and in group II maintained with remifentanil and propofol. Oxygenation, heart rate, respiratory rate, coughing, bucking, laryngospasm, bronchospasm were evaluated during and after surgery. Also Operation success and surgeon’s satisfaction were recorded as well.Results: Demographic findings were the same in both groups. Oxygenation and heart rate were more stable in group II (P=0.047 and P=0.026 respectively but there was no significant difference in respiratory rate between two groups (P=1. Success rate was also similar in both groups but surgeon’s satisfaction was significantly higher in TIVA (P=0.003. There was not any significant different between complications in two groups. Conclusion: We suggest TIVA for rigid bronchoscopy because of better oxygenation, more homodynamic stability, surgeon’s satisfaction, lack of air pollution and less interference with surgeon’s visual field.

    Herminghaus, A; Löser, S; Wilhelm, W

    2012-04-01

    Part 2 of this review on geriatric anesthesia primarily describes the multiple influences of age on the pharmacokinetics and pharmacodynamics of different anesthetic agents and their impact on clinical practice. In the elderly the demand for opioids is reduced by almost 50% and with total intravenous anesthesia the dosages of propofol and remifentanil as well as recovery times are more determined by patient age than by body weight. As a result depth of anesthesia monitoring is recommended for geriatric patients to individually adjust the dosing to patients needs. With muscle relaxants both delayed onset of action and prolonged duration of drug effects must be considered with increasing age and as this may lead to respiratory complications, neuromuscular monitoring is highly recommended. The following measures appear to be beneficial for geriatric patients: thorough preoperative assessment, extended hemodynamic monitoring, use of short-acting anesthetics in individually adjusted doses best tailored by depth of anesthesia monitoring, intraoperative normotension, normothermia and normocapnia, complete neuromuscular recovery at the end of the procedure and well-planned postoperative pain management in order to reduce or avoid the use of opioids.

    Full Text Available Free radical and peroxide production lead to intracellular damage. On the other hand, free radicals are used by the human immune system to defend against pathogens. The aging process could be limited by oxidative stress in the short term. Chronic diseases like diabetes mellitus (DM are full-stress conditions in which remarkable metabolic functional destructions might happen. There is strong evidence regarding antioxidant impairment in diabetes. Performing a particular method for anesthesia in diabetic patients might prevent or modify excessive free radical formation and oxidative stress. It seems that prescribing antioxidant drugs could promote wound healing in diabetics.

    Possibilities of pharmacological correction of the patient's mental state while performing Ketamin anesthesia were studied. The optimal results were obtained by the complex of Seduxen prior to and Pyracetam after anesthesia. It considerably reduced the frequency and degree of hallucinative--illusional disturbances and simultaneously markedly accelerated the restoration of the disturbed consciousness.

    The human heart normally exhibits robust beat-to-beat heart rate variability (HRV). The loss of this variability is associated with pathology, including disease states such as congestive heart failure (CHF). The effect of general anesthesia on intrinsic HRV is unknown. In this prospective, observational study we enrolled 100 human subjects having elective major surgical procedures under general anesthesia. We recorded continuous heart rate data via continuous electrocardiogram before, during, and after anesthesia, and we assessed HRV of the R-R intervals. We assessed HRV using several common metrics including Detrended Fluctuation Analysis (DFA), Multifractal Analysis, and Multiscale Entropy Analysis. Each of these analyses was done in each of the four clinical phases for each study subject over the course of 24 h: Before anesthesia, during anesthesia, early recovery, and late recovery. On average, we observed a loss of variability on the aforementioned metrics that appeared to correspond to the state of general anesthesia. Following the conclusion of anesthesia, most study subjects appeared to regain their normal HRV, although this did not occur immediately. The resumption of normal HRV was especially delayed on DFA. Qualitatively, the reduction in HRV under anesthesia appears similar to the reduction in HRV observed in CHF. These observations will need to be validated in future studies, and the broader clinical implications of these observations, if any, are unknown.

    The depth of anesthesia estimation has been one of the most research interests in the field of EEG signal processing in recent decades. In this paper we present a new methodology to quantify the depth of anesthesia by quantifying the dynamic fluctuation of the EEG signal. Extraction of useful information about the nonlinear dynamic of the brain during anesthesia has been proposed with the optimum Fractal Scaling Exponent. This optimum solution is based on the best box sizes in the Detrended Fluctuation Analysis (DFA) algorithm which have meaningful changes at different depth of anesthesia. The Fractal Scaling Exponent (FSE) Index as a new criterion has been proposed. The experimental results confirm that our new Index can clearly discriminate between aware to moderate and deep anesthesia levels. Moreover, it significantly reduces the computational complexity and results in a faster reaction to the transients in patients' consciousness levels in relations with the other algorithms.

    Hypothermia and shivering are common during epidural anesthesia for cesarean delivery but are not always accompanied by a sensation of coldness. To test the hypothesis that central temperature changes are not perceived during epidural anesthesia, we measured central and skin temperatures and thermal perception in 30 patients undergoing cesarean delivery with epidural anesthesia. Central temperature decreased 1.0 +/- 0.6 degrees C from control values during anesthesia and surgery, but thermal perception scores did not reflect central temperatures (P = 0.56) or changes in central temperature (P = 0.63). A feeling of warmth was significantly correlated with increased mean skin temperature (P = 0.02) and increased upper body skin temperature (P = 0.03). We conclude that central temperature is poorly perceived and is less important than skin temperature in determining thermal perception during high levels of epidural anesthesia.

    The authors of this prospective study initially hypothesized that hypnosis would lower the anxiety and pain associated with dental anesthesia. Thirty children aged 5 to 12 were randomly assigned to 2 groups receiving hypnosis (H) or not (NH) at the time of anesthesia. Anxiety was assessed at inclusion in the study, initial consultation, installation in the dentist's chair, and at the time of anesthesia using the modified Yale preoperative anxiety scale (mYPAS). Following anesthesia, a visual analogue scale (VAS) and a modified objective pain score (mOPS) were used to assess the pain experienced. The median mYPAS and mOPS scores were significantly lower in the H group than in the NH group. Significantly more children in the H group had no or mild pain. This study suggests that hypnosis may be effective in reducing anxiety and pain in children receiving dental anesthesia.

    Purpose Traditionally acceptable methods of anesthesia for vitrectomy surgery are quite varied. However, each of these methods has its own potential for complications that can range from minor to severe. The surgery procedure of vitrectomy for symptomatic vitreous floaters is much simpler, mainly reflecting in the nonuse of sclera indentation, photocoagulation, and the apparently short surgery duration. The use of 27-gauge cannulae makes the puncture of the sclera minimally invasive. Hence, retrobulbar anesthesia, due to its rare but severe complications, seemed excessive for this kind of surgery. Method Three cases of 27-gauge, sutureless pars plana vitrectomy for symptomatic vitreous floaters with topical anesthesia are reported. Results The vitrectomy surgeries were successfully performed with topical anesthesia (proparacaine, 0.5%) without operative or postoperative complications. Furthermore, none of the patients experienced apparent pain during or after the surgery. Conclusion Topical anesthesia can be considered for 27-guage vitrectomy in patients with symptomatic vitreous floaters. PMID:28203195

    Obesity is associated with serious morbidity during pregnancy, and obese women also are at a high risk of developing complications during labor, leading to an increased risk for instrumental and Cesarean deliveries. The engagement of the obstetrical anesthetist in the management of this group of high-risk patients should be performed antenatally so that an appropriate management strategy can be planned in advance to prevent an adverse outcome. Good communication between all care providers is essential. The obese patient in labor should be encouraged to have a functioning epidural catheter placed early in labor. Apart from providing analgesia and alleviating physiological derangements during labor, the presence of a functioning epidural catheter can also be used to induce anesthesia quickly in the event of an emergency cesarean section, thus avoiding a general anesthesia, which has exceedingly high risks in the obese parturient. Successful management of the obese patient necessitates a comprehensive strategy that encompasses a multidisciplinary and holistic approach from all care-providers.

    Leroy D Vandam, MD was a remarkable man--an intricate amalgamation of an artist, scientist, and physician. He was a bastion of medical historical knowledge. Dr Vandam became a most influential anesthesiologist, some say, a giant. He was an example of someone who, with resolve, overcame adversity. His artwork is displayed in countless places, and several of his paintings form part of the Wood Library Museum Heritage Series. Dr Vandam was first a surgeon, but he abandoned surgery and pursued a career in anesthesiology under the leadership of Robert Dripps. He completed his residency training at the University of Pennsylvania and joined its staff in 1949. When he arrived at Brigham and Women's Hospital in the 1950s as director of anesthesia, he embarked on one of the most illustrious careers in American anesthesiology. Dr Vandam published more than 250 original articles, chapters, abstracts, and other reports on a wide variety of subjects including history, art, and pharmacology. His classic article on the complications of neuroaxial blocks is a seminal work in anesthesiology. This article describes how an anesthesiologist who shared an interest with Dr Vandam in the history of anesthesiology came to produce a movie based on his career, the evolution of anesthesia equipment, and the transformation of our specialty.

    Full Text Available ABSTRACT: Introduction & Objective: Transurethral Resection of Prostate (TURP is usually performed under regional or general anesthesia. An alternative to conventional anesthesia is performing of TURP under local anesthetic infiltration with sedation. The aim of this study was to evaluate the efficacy and complication of sedoanalgesia in TURP. Material & Methods: In a prospective clinical trial from September 2006 to December 2007, 60 patients (30 in each group with prostate hypertrophy, candidate for TURP, were randomly assigned into two groups. In the first group, standard spinal anesthesia was done. In the second group, five minutes before the operation, 25 mgs of diazepam plus 25-50 mgs of pethedine was intravenously administered followed by injection of 10 ml lidocaine 2% gel in the urethra and the skin in the suprapubic area was anesthetized with 2 ml of 1% lidocaine. Using a 22 gauge nephrostomy needle, the suprapubic skin was punctured and the needle was directed toward prostate apex and 10-20ml of 1% lidocaine was injected at the serosal aspect of the rectal wall. For dorsal nerve block, 5-10ml of 1% lidocaine was injected at penopubic junction, and then a standard TURP was performed. Patients were switched to another anesthetic technique if the selected technique failed. Severity of pain was assessed by visual analogue scale. Results: The average prostate size was 25 grs (range10-50grs in the local anesthetic group (group 1 and 27.5 grs (range 10-50 grs in the spinal group (group2. In the local anesthetic group, 82.3% had no or mild pain while moderate to severe pain was reported in 16, 7% of the patients.

    Full Text Available Equine veterinarians frequently anesthetize horses. In majority of cases performing short-term anesthesia (duration, 20 minutes. But there is substantial need for long term anesthesia. The aim of this work is to present our experience with a long term and short term total intravenous anesthesia in horses. In this paper we are presenting results of anesthesia monitoring of a horse undergoing surgical remove of an abdominal testis (complete abdominal cryptorchid. Sedation of the horse was conducted with xylazine, 1.0 mg/kg, iv, and midazolam 0.06 mg/kg, iv. The total anesthesia was induced using a combination of ketamine 2.2mg/kg/iv, and midazolam 0.1 mg/kg/iv. After induction the horse was restrained and anesthesia was maintained with continuous intravenous drip of a combination of drugs mixed in infusion bottle with midazolam (0.002 mg/kg/min, ketamine (0.03 mg/kg/min, and xylazine (0.016 mg/kg/min. Additional ketamine (0.03 mg/kg and midazolam 0.03 mg/kg/iv was administered if the horse moved its head or limbs during the procedure. The duration of anesthesia was 90 minutes. During this time cardiopulmonary parameters and reflexes were monitored continuously.The recovery of anesthesia was 30 minutes and horse stood on the first attempt 40 minutes. Midazolam, ketamine, and xylazine in combination produced TIVA in this horse and can be used for short term, middle term, and longer lasting surgical procedures in the field.

Meta-analyses and reviews of acupuncture and related techniques for postoperative nausea and vomiting (POVN and postoperative vomiting (POV show promising results while many clinicians remain skeptical of the value of acupuncture. Given the interest in finding safe non-pharmacological approaches toward postoperative care, this body of knowledge needs to be considered. This review critically appraises and summarizes the research on acupuncture and acupressure in ambulatory anesthesia during the last 15 years.Methods: Articles were identified through searches of Medline, PubMed, and Embase using the search terms “acupuncture” or “acupuncture therapy” in combination with “ambulatory anesthesia” or “ambulatory surgery” or “day surgery” or “postoperative”. A corresponding search was done using “acupressure” and “wristbands”. The searches generated a total of 104, 118, and 122 references, respectively.Results: Sixteen studies were included; eight studies reported on acupuncture and eight on acupressure. Nine studies found acupuncture or acupressure effective on primary endpoints including postoperative nausea and vomiting, postoperative pain, sore throat, and emergence agitation. Four studies found acupuncture had a similar effect to antiemetic medication.Conclusion: Overall, the studies were of fairly good quality. A large proportion of the reviewed papers highlights an effect of acupuncture or acupressure on postoperative morbidities in an ambulatory setting

    Full Text Available AIM: Aim of our study to compare the spinal anaesthesia and general anaesthesia in children undergoing surgeries below umbilicus. OBJECTIVE: to assess the patient comfort in pt. with GA and pt. with spinal anaesthesia, the adequate surgical condition, assess the hemodynamic change, assess the post op analgesia and to assess the post op complication. MATERIAL AND METHOD: 60 ASA grade I & II children of either sex, aged 5-12 yrs undergoing elective surgeries for the lower abdominal, perineal and lower limb surgeries were taken. After taking a detailed history, thorough general physical examination, all pertinent investigation were carried out to exclude any systemic disease. Patients were classified randomly into 2 groups (30 patients in each group. Group A: General anesthesia was given. Group P: subarachnoid block was given. Intraoperative monitoring consisted of SPO2, PR, NIBP, RR and assessment of duration of post-operative analgesia. P-value <0.05 consider significant. RESULT: Analysis revealed that there were no significant differences between the patients with respect to age, sex, duration and type of surgery In SAB since less general anaesthetic drug including parental opioid are used the risk and postoperative respiratory depression is minimal. The stress response to surgery is also limited and recovery is fast. Postoperatively complications like sore throat, laryngeal irritation, cough etc. was also less associated with it. CONCLUSION pediatric spinal anesthesia is not only a safe alternative to general anesthesia but often the anesthesia technique of choice in many lower abdominal and lower limb surgeries in children. The misconception regarding its safety and flexibility is broken and is now found to be even more cost effective. It is much preferred technique special for common day case surgeries generally performed in the pediatric age group.

    Inguinal hernia repair is one of the most common procedures in general surgery. All anesthetic methods can be used in inguinal hernia repairs. Local anesthesia for groin hernia repair had been introduced at the very beginning of the last century, and gained popularity following the success reports from the Shouldice Hospital, and the Lichtenstein Hernia Institute. Today, local anesthesia is routinely used in specialized hernia clinics, whereas its use is still not a common practice in general hospitals, in spite of its proven advantages and recommendations by current hernia repair guidelines. In this review, the technical options for local anaesthesia in groin hernia repairs, commonly used local anaesthetics and their doses, potential complications related to the technique are evaluated. A comparison of local, general and regional anesthesia methods is also presented. Local anaesthesia technique has a short learning curve requiring simple training. It is easy to learn and apply, and its use is in open anterior repairs a nice way for health care economics. Local anesthesia has been shown to have certain advantages over general and regional anesthesia in inguinal hernia repairs. It is more economic and requires a shorter time in the operating room and shorter stay in the institution. It causes less postoperative pain, requires less analgesic consumption; avoids nausea, vomiting, and urinary retention. Patients can mobilize and take oral liquids and solid foods much earlier. Most importantly, local anesthesia is the most suitable type of anesthesia in elder, fragile patients and patients with ASA II-IV scores.

    Full Text Available The purpose of this study was to determine if differences in behavior exist following dental treatment under hospital-based general anesthesia (HBGA or office-based general anesthesia (OBGA in the percentage of patients exhibiting positive behavior and in the mean Frankl scores at recall visits. This retrospective study examined records of a pediatric dental office over a 4 year period. Patients presenting before 48 months of age for an initial exam who were diagnosed with early childhood caries were included in the study. Following an initial exam, patients were treated under HBGA or OBGA. Patients were followed to determine their behavior at 6-, 12- and 18-month recall appointments. Fifty-four patients received treatment under HBGA and 26 were treated under OBGA. OBGA patients were significantly more likely to exhibit positive behavior at the 6- and 12-month recall visits p = 0.038 & p = 0.029. Clinicians should consider future behavior when determining general anesthesia treatment modalities in children with early childhood caries presenting to their office.

    Full Text Available BACKGROUND AND OBJECTIVES: Patient's satisfaction is a standard indicator of care quality. The aim of this study was to evaluate whether a preoperative oral ingestion of 200 mL of a carbohydrate drink can improve comfort and satisfaction with anesthesia in elderly patients with hip fracture. METHOD: Prospective randomized clinical trial conducted in a Brazilian public hospital, with patients ASA I-III undergoing surgery for hip fracture. The control group (NPO received nothing by mouth after 9:00 p.m. the night before, while patients in the experimental group (CHO received 200 mL of a carbohydrate drink 2-4 h before the operation. Patients' characteristics, subjective perceptions, thirst and hunger and satisfaction were determined in four steps. Mann-Whitney U-test and Fisher exact test were used for comparison of control and experimental groups. A p-value <0.05 was considered significant. RESULTS: A total of 100 patients were included in one of the two regimens of preoperative fasting. Fasting time decreased significantly in the study group. Patients drank 200 mL 2:59 h before surgery and showed no hunger (p < 0.00 and thirst on arrival to OR (p < 0.00, resulting in increased satisfaction with the perioperative anesthesia care (p < 0.00. CONCLUSIONS: The satisfaction questionnaire for surgical patient could become a useful tool in assessing the quality of care. In conclusion, CHO significantly reduces preoperative discomfort and increases satisfaction with anesthesia care.

    2014-01-01

    Full Text Available Although propofol has been the backbone for sedation in gastrointestinal endoscopy, both anesthesiologists and endoscopists are faced with situations where an alternative is needed. Recent national shortages forced many physicians to explore these options. A midazolam and fentanyl combination is the mainstay in this area. However, there are other options. The aim of this review is to explore these options. The future would be, invariably, to move away from propofol. The reason is not in any way related to the drawbacks of propofol as a sedative. The mandate that requires an anesthesia provider to administer propofol has been a setback in many countries. New sedative drugs like Remimazolam might fill this void in the future. In the meantime, it is important to keep an open eye to the existing alternatives.

  19. Neurologic deficits and arachnoiditis following neuroaxial anesthesia.

    Science.gov (United States)

    Aldrete, J A

    2003-01-01

    Of late, regional anesthesia has enjoyed unprecedented popularity; this increase in cases has brought a higher frequency of instances of neurological deficit and arachnoiditis that may appear as transient nerve root irritation, cauda equina, and conus medullaris syndromes, and later as radiculitis, clumped nerve roots, fibrosis, scarring dural sac deformities, pachymeningitis, pseudomeningocele, and syringomyelia, etc., all associated with arachnoiditis. Arachnoiditis may be caused by infections, myelograms (mostly from oil-based dyes), blood in the intrathecal space, neuroirritant, neurotoxic and/or neurolytic substances, surgical interventions in the spine, intrathecal corticosteroids, and trauma. Regarding regional anesthesia in the neuroaxis, arachnoiditis has resulted from epidural abscesses, traumatic punctures (blood), local anesthetics, detergents, antiseptics or other substances unintentionally injected into the spinal canal. Direct trauma to nerve roots or the spinal cord may be manifested as paraesthesia that has not been considered an injurious event; however, it usually implies dural penetration, as there are no nerve roots in the epidural space posteriorly. Sudden severe headache while or shortly after an epidural block using the loss of resistance to air approach usually suggests pneumocephalus from an intradural injection of air. Burning severe pain in the lower back and lower extremities, dysesthesia and numbness not following the usual dermatome distribution, along with bladder, bowel and/or sexual dysfunction, are the most common symptoms of direct trauma to the spinal cord. Such patients should be subjected to a neurological examination followed by an MRI of the effected area. Further spinal procedures are best avoided and the prompt administration of IV corticosteroids and NSAIDs need to be considered in the hope of preventing the inflammatory response from evolving into the proliferative phase of arachnoiditis.

    Computer-controlled local anesthetic delivery (C-CLAD) devices and systems for intraosseous (IO) injection are important additions to the dental anesthesia armamentarium. C-CLAD using slow infusion rates can significantly reduce the discomfort of local anesthetic infusion, especially in palatal tissues, and facilitate palatal approaches to pulpal nerve block that find special use in cosmetic dentistry, periodontal therapy, and pediatric dentistry. Anesthesia of single teeth can be obtained using either C-CLAD intraligamentary injections or IO injections. Supplementary IO anesthesia is particularly suited for providing effective pain control of teeth diagnosed with irreversible pulpitis.

    Full Text Available CONTEXT AND OBJECTIVES: In major orthopedic surgery of the lower limbs, continuous spinal anesthesia (CSA and combined spinal epidural anesthesia (CSE are safe and reliable anesthesia methods. In this prospective randomized clinical study, the blockading properties and side effects of CSA were compared with single interspace CSE, among patients scheduled for major hip or knee surgery. DESIGN AND SETTING: Prospective clinical study conducted at the Institute for Regional Anesthesia, Hospital de Base, São José do Rio Preto. METHODS: 240 patients scheduled for hip arthroplasty, knee arthroplasty or femoral fracture treatment were randomly assigned to receive either CSA or CSE. Blockades were performed in the lateral position at the L3-L4 interspace. Puncture success, technical difficulties, paresthesia, highest level of sensory and motor blockade, need for complementary doses of local anesthetic, degree of technical difficulties, cardiocirculatory changes and postdural puncture headache (PDPH were recorded. At the end of the surgery, the catheter was removed and cerebrospinal fluid leakage was evaluated. RESULTS: Seven patients were excluded (three CSA and four CSE. There was significantly lower incidence of paresthesia in the CSE group. The resultant sensory blockade level was significantly higher with CSE. Complete motor blockade occurred in 110 CSA patients and in 109 CSE patients. Arterial hypotension was observed significantly more often in the CSE group. PDPH was observed in two patients of each group. CONCLUSION: Our results suggest that both CSA and CSE provided good surgical conditions with low incidence of complications. The sensory blockade level and hemodynamic changes were lower with CSA.

    2011-01-01

    Full Text Available Objectives: Spinal anesthesia has the advantage that profound nerve block can be produced in a large part of the body by the relatively simple injection of a small amount of local anesthetic. Intrathecal local anesthetics have limited duration. Different additives have been used to prolong spinal anesthesia. The effect of corticosteroids in prolonging the analgesic effects of local anesthetics in peripheral nerves is well documented. The purpose of this investigation was to determine whether the addition of dexamethasone to intrathecal bupivacaine would prolong the duration of sensory analgesia or not. Methods: We conducted a randomized, prospective, double-blind, case-control, clinical trial. A total of 50 patients were scheduled for orthopedic surgery under spinal anesthesia. The patients were randomly allocated to receive 15 mg hyperbaric bupivacaine 0.5% with 2 cc normal saline (control group or 15 mg hyperbaric bupivacaine 0.5% plus 8 mg dexamethasone (case group intrathecally. The patients were evaluated for quality, quantity, and duration of block; blood pressure, heart rate, nausea, and vomiting or other complications. Results: There were no signification differences in demographic data, sensory level, and onset time of the sensory block between two groups. Sensory block duration in the case group was 119±10.69 minutes and in the control group was 89.44±8.37 minutes which was significantly higher in the case group (P<0.001. The duration of analgesia was 401.92±72.44 minutes in the case group; whereas it was 202±43.67 minutes in the control group (P<0.001. The frequency of complications was not different between two groups. Conclusion: This study has shown that the addition of intrathecal dexamethasone to bupivacaine significantly improved the duration of sensory block in spinal anesthesia without any changes in onset time and complications.

    ABSTRACT Background: Music therapy, an innovative approach that has proven effectiveness in many medical conditions, seems beneficial also in managing surgical patients. The aim of this study is to evaluate its effects, under general anesthesia, on perioperative patient satisfaction, stress, pain, and awareness. Methods: This is a prospective, randomized, double-blind study conducted in the operating theatre of visceral surgery at Sahloul Teaching Hospital over a period of 4 months. Patients aged more than 18 undergoing a scheduled surgery under general anesthesia were included. Patients undergoing urgent surgery or presenting hearing or cognitive disorders were excluded. Before induction, patients wore headphones linked to an MP3 player. They were randomly allocated into 2 groups: Group M (with music during surgery) and group C (without music). Hemodynamic parameters, quality of arousal, pain experienced, patient’s satisfaction, and awareness incidence during anesthesia were recorded. Results: One hundred and forty patients were included and allocated into 2 groups that were comparable in demographic characteristics, surgical intervention type and anesthesia duration. Comparison of these two groups regarding the hemodynamic profile found more stability in group M for systolic arterial blood pressure. A calm recovery was more often noted in group M (77.1% versus 44%, p < 10–3). The average Visual Analog Scale (VAS) score was lower in the intervention group (33.8 ± 13.63 versus 45.1 ± 16.2; p < 10–3). The satisfaction rate was significantly higher among the experimental group (81.4% versus 51.4%; p < 10–3). The incidence of intraoperative awareness was higher in group C (8 cases versus 3 cases) but the difference was not statistically significant. Conclusion: Music therapy is a non-pharmacological, inexpensive, and non-invasive technique that can significantly enhance patient satisfaction and decrease patients’ embarrassing experiences related

    BackgroundMultiple nations are actively pursuing manned exploration of space beyond low-earth orbit. The responsibility to improve surgical care for spaceflight is substantial. Although the use of parabolic flight as a terrestrial analogue to study surgery in weightlessness (0 g) is well described, minimal data is available to guide the appropriate delivery of anesthesia. After studying anesthetized pigs in a 0 g parabolic flight environment, our group developed a comprehensive protocol describing prolonged anesthesia in a parabolic flight analogue space surgery study (PFASSS). Novel challenges included a physically remote vivarium, prolonged (>10 h) anesthetic requirements, and the provision of veterinary operating room/intensive care unit (ICU) equivalency on-board an aircraft with physical dimensions of ethical approval, multiple ground laboratory sessions were conducted with combinations of anesthetic, pre-medication, and induction protocols on Yorkshire-cross specific pathogen-free (SPF) pigs. Several constant rate infusion (CRI) intravenous anesthetic combinations were tested. In each regimen, opioids were administered to ensure analgesia. Ventilation was supported mechanically with blended gradients of oxygen. The best performing terrestrial 1 g regime was flight tested in parabolic flight for its effectiveness in sustaining optimal and prolonged anesthesia, analgesia, and maintaining hemodynamic stability. Each flight day, a fully anesthetized, ventilated, and surgically instrumented pig was transported to the Flight Research Laboratory (FRL) in a temperature-controlled animal ambulance. A modular on-board surgical/ICU suite with appropriate anesthesia/ICU and surgical support capabilities was employed. ResultsThe mean duration of anesthesia (per flight day) was 10.28 h over four consecutive days. A barbiturate and ketamine-based CRI anesthetic regimen supplemented with narcotic analgesia by bolus administration offered the greatest prolonged hemodynamic

    Conclusions: The administration of thoracic epidural anesthesia, either combined with propofol or isoflurane, was not associated with a relevant impairment of oxygenation during OLV. Therefore Pre-emptive analgesia via an epidural thoracic catheter can be used safely as a standard in lung surgery, decreasing the anesthesia requirements when combined with GA, maximizing the benefits of each form of anesthesia and improving the outcome in patients with cardiopulmonary diseases, hence it was found that it has no effect on oxygenation during OLV, and it is associated with stable hemodynamics.

    Full Text Available The analgesic effects of three different doses of tramadol as a preanesthetic in medetomidine-ketamine anesthesia in dogs were compared. Twenty-eight healthy adult mongrel dogs were used. The dogs were divided into four groups at random; 1 ml kg-1 of normal saline, 1, 2 or 4mg kg-1 of tramadol premedication (group Control, TRA1, TRA2 and TRA4 was then administered intravenously followed by medetomidine and ketamine anesthesia. The behavioral changes, the duration of surgical anesthesia, blood gas parameters (pH, pO2, and pCO2, heart rate, and systolic/diastolic pressure were observed. Tramadol (4mg kg-1 pretreatment significantly increased the degree of sedation when compared with the control, TRA1 and TRA2 groups at 15 min after tramadol administration (P<0.05. The duration of surgical anesthesia was significantly increased by tramadol (4mg kg-1 pretreatment when compared with that of the control group (P<0.05. There were no significant differences in behavioral changes, blood gas parameters (pH, pO2 and pCO2, heart rate, and arterial pressure among the groups. Tramadol at 4mg kg-1 did not affect the cardiovascular system and recovery of anesthesia, but significantly increased the duration of surgical anesthesia with medetomidine and ketamine. This result suggests that intravenous tramadol at 4mg kg-1 is a useful preanesthetic agent for extending the surgical level of anesthesia in medetomidine-ketamine anesthesia in dogs.

    The mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome is a disease triggered by a disorder in energy production within mitochondria. The cause of this syndrome is a mutation in the mitochondrial DNA where in 80% of cases an A-to-G mutation is present at nucleotide 3243 and with a prevalence of 18.4/100,000 in the population. Predominantly affected are organ systems with a high energy metabolism, such as the heart, brain and musculature. During the premedication visit a thorough patient history and examination with respect to neurological impairments must be carried out. Epilepsy and the appropriate permanent medication lead to possible alterations in effectiveness of anesthetics and muscle relaxants which are difficult to predict. An extensive patient cardiac history and a preoperative electrocardiogram (ECG) for an appraisal of possible disorders in the cardiac conduction system and when necessary extended cardiac diagnostics, are recommended. The monitoring must be adapted depending on the functional limitations and the forthcoming intervention and when necessary a postoperative surveillance in an intensive care unit should be initiated. Knowledge of the special features of MELAS syndrome in association with a consideration of the characteristics of anesthesia in MELAS patients and an individually adapted intensified perioperative surveillance, can contribute to a reduction in perioperative morbidity in patients suffering from MELAS syndrome.

    Full Text Available Intravenous injection of anesthetic drugs dates back to the 17th Century when opium and chloral hydrate have been injected intravenously. It was not until the 1930s intravenous anesthesia became popular with the invention of barbiturates.Early intravenous anesthetic agents such as barbiturates were ideal for induction of anesthesia, but not suitable for maintenance of anesthesia. Most of these drugs accumulated significantly with increasing durations of infusion and also resulted in cardiorespiratory depression. The invention of propofol and shorter acting opioid analgesics such as remifentanil and alfentanil have revolutionized intravenous anesthesia. The rapid onset and offset of these drugs lends itself to being suitable agents for maintenance of anesthesia over prolonged periods of time. Detailed understanding of the pharmacokinetics of propofol and remifentanil, combined with technological advances in intravenous pumps capable of accurate delivery of drugs have resulted in great development of the field of total intravenous anesthesia and target controlled infusions. I would like to discuss, in this article, the pharmacokinetics and pharmacokinetic models behind these intravenous infusion pumps. [Int J Basic Clin Pharmacol 2014; 3(3.000: 417-423

    For many prenatally diagnosed conditions, treatment is possible before birth. These fetal procedures can range from minimal invasive punctions to full open fetal surgery. Providing anesthesia for these procedures is a challenge, where care has to be taken for both mother and fetus. There are specific physiologic changes that occur with pregnancy that have an impact on the anesthetic management of the mother. When providing maternal anesthesia, there is also an impact on the fetus, with concerns for potential negative side effects of the anesthetic regimen used. The question whether the fetus is capable of feeling pain is difficult to answer, but there are indications that nociceptive stimuli have a physiologic reaction. This nociceptive stimulation of the fetus also has the potential for longer-term effects, so there is a need for fetal analgesic treatment. The extent to which a fetus is influenced by the maternal anesthesia depends on the type of anesthesia, with different needs for extra fetal anesthesia or analgesia. When providing fetal anesthesia, the potential negative consequences have to be balanced against the intended benefits of blocking the physiologic fetal responses to nociceptive stimulation.

    Today's practice of medicine involves ever more complex patients whose care is coordinated with multidisciplinary teams. Caring for these patients can challenge all members of the health care team. Sedation/anesthesia in infants/toddlers as well as uncooperative or intellectually or emotionally impaired children who require imaging studies of the chest are ongoing challenges. High-quality computed tomography (CT) chest imaging studies in children under general anesthesia are extremely important for accurate interpretation and subsequent medical decision-making. Anesthesia-induced atelectasis may obscure or mimic true pathology creating a significant quality issue. Obtaining a high-quality, motion-free chest imaging study in infants and children under general anesthesia remains a difficult task in many institutions. Meticulous attention to anesthesia and imaging techniques and specialized knowledge are required to properly perform and interpret chest imaging studies. In this commentary, we discuss the continuous struggle to obtain high-quality CT chest imaging under general anesthesia. We will also discuss the major concerns of the anesthesiologist, radiologist and pulmonologist and why cooperation and coordination among these providers are critical for an optimal quality study.

    The rationale for cost-effectiveness of modern muscle relaxants (MR) administration in general anesthesia was evaluated. New MRs are more expensive than traditionally used pipecuronium and succinylcholine. However, the old MRs are often required as a block reversion with anticholinesterase medicines at the end of surgery, the longer artificial lung ventilation and observation in patients during recovery in intensive care unit. It was found that the district military hospital had done an annual average of about 900 general anesthesia assisted with artificial ventilation and muscle relaxation. About 2% of all anesthesias accrue to short-term anesthesia, the 27% to medium-term and 71% to long-term. 81% of the medium-term anesthesia accrue small hospitals. According to cost/effectiveness the most optimal muscle relaxants administration scheme for short-term (up to 30 min) anesthesia was mivacurium, for the operation of medium duration (30-120 min)--rocuronium, for long-term (120 min)--pipecuronium. An electronic form of annual report, which allows to obtain the necessary data for calculation of annual muscle relaxants demand and costs both in hospital and in the whole of the armed forces quickly, was developed.

    Full Text Available Introduction: Intraoral local anesthesia is essential for delivering dental care. Needless devices have been developed to provide anesthesia without injections. Little controlled research is available on its use in dental restorative procedures in adult patients. The aims of this study were to compare adult patients acceptability and preference for needleless jet injection with classical local infiltration as well as to evaluate the efficacy of the needleless anesthesia. Materials and Methods: Twenty non fearful adults with no previous experience of dental anesthesia were studied using split-mouth design. The first procedure was performed with classical needle infiltration anesthesia. The same amount of anesthetic solution was administered using MADA jet needleless device in a second session one week later, during which a second dental restorative procedure was performed. Patients acceptance was assessed using Universal pain assessment tool while effectiveness was recorded using soft tissue anesthesia and pulpal anesthesia. Patients reported their preference for the anesthetic method at the third visit. The data was evaluated using chi square test and student′s t-test. Results: Pressure anesthesia was more accepted and preferred by 70% of the patients than traditional needle anesthesia (20%. Both needle and pressure anesthesia was equally effective for carrying out the dental procedures. Conclusion: Patients experienced significantly less pain and fear (p<0.01 during anesthetic procedure with pressure anesthesia. However, for more invasive procedures needle anesthesia will be more effective.

  4. Reactive Software Agent Anesthesia Decision Support System

    2011-12-01

    Full Text Available Information overload of the anesthesiologist through technological advances have threatened the safety of patients under anesthesia in the operating room (OR. Traditional monitoring and alarm systems provide independent, spatially distributed indices of patient physiological state. This creates the potential to distract caregivers from direct patient care tasks. To address this situation, a novel reactive agent decision support system with graphical human machine interface was developed. The system integrates the disparate data sources available in the operating room, passes the data though a decision matrix comprising a deterministic physiologic rule base established through medical research. Patient care is improved by effecting change to the care environment by displaying risk factors and alerts as an intuitive color coded animation. The system presents a unified, contextually appropriate snapshot of the patient state including current and potential risk factors, and alerts of critical patient events to the operating room team without requiring any user intervention. To validate the efficacy of the system, a retrospective analysis focusing on the hypotension rules were performed. Results show that even with vigilant and highly trained clinicians, deviations from ideal patient care exist and it is here that the proposed system may allow more standardized and improved patient care and potentially outcomes.

    Breast augmentation is one of the leading esthetic surgeries, enjoying high satisfaction rates. Pain, nausea, and vomiting are frequent shortcomings of the immediate postoperative period. The aim of this study was to compare breast augmentation from the anesthetic point of view: general anesthesia (GA) versus monitored anesthesia care (MAC). The charts of 115 patients were reviewed in this retrospective study performed over a period of 2 years. Sixty-nine women chose to have the surgery done under MAC, and 46 under GA. Statistically significant differences were noted in both postoperative hospital stay (16.1 +/- 6.78 hours vs. 11.7 +/- 6.10 hours) and frequency of vomiting (mean, 0.5 vs. 0.22 times per patient) after GA and MAC, respectively (Mann-Whitney, P < 0.01). Postoperative pain, assessed using the visual analog scale, was significantly higher (mean visual analog scale, 5 vs. 3.27) when the prosthesis was placed in the submuscular plane compared with the subglandular plane (Mann-Whitney, P = 0.043). When offered a choice, more women preferred MAC over GA for their breast augmentation procedure. Less vomiting and shorter postoperative hospitalization were prominent in the MAC group.

    Background Surgical stress causes a helper T-cell type 2 (Th2)-dominant status and disturbs the Th1/Th2 cytokine balance. Anesthesia can suppress the stress response to surgery, therefore it may inhibit the imbalance in the Th1/Th2 ratio. In this study, we assessed if propofol anesthesia and sevoflurane anesthesia influence the Th1/Th2 cytokine balance, and which anesthesia method better attenuates this ratio.Methods Twenty-eight patients with an American Society of Anesthesiologists (ASA) physical status of I undergoing laparoscopic cholecystectomy were selected. They were randomly allocated into two groups of 14. Group 1 received propofol anesthesia by a target-controlled-infusion (TCI) pump and group 2 received sevoflurane anesthesia.Non-invasive blood pressure, heart rate, and end-expiration CO2 partial pressure were monitored during anesthesia. The depth of anesthesia was measured using the bispectral index (BIS), and maintained between 50 and 60. During surgery we adjusted the doses of propofol and sevoflurane according to the BIS. Samples of peripheral blood were taken before the induction of anesthesia (T1), after the induction of anesthesia (T2), at the beginning of surgery (T3), at the end of surgery (T4) and on the first day after surgery (D1). Blood samples were analyzed to give the Th1/Th2 ratio and plasma level of cortisol.Results Non-invasive blood pressure, heart rate and end-expiration CO2 partial pressure were not notably different in the two groups. At T4, the percentage of T1 cells was higher in group 1 and had statistical significance (P <0.05). The percentage of T2 cells was not significantly different in the two groups. At T4, the difference in the Th1/Th2 ratio was significantly different. At T3, T4, and D1, the plasma level of cortisol was lower in group 1(P <0.05).Conclusion Compared with sevoflurane, propofol can preferably promote Th cells to differentiate into Th1 cells and inhibit surgical stress. Propofol may therefore be

    Full Text Available Aims: In our group, after a study showing that spinal anesthesia is safe when compared with general anesthesia, spinal anesthesia has been the technique of choice for this procedure. This is a prospective study with all patients undergoing LC under spinal anesthesia in our department since 2007. Settings and Design: Prospective observational. Materials and Methods: From 2007 to 2011, 369 patients with symptoms of colelithiasis, laparoscopic cholecystectomy were operated under spinal anesthesia with pneumoperitoneum and low pressure CO 2. We compared 15 mg of hyperbaric bupivacaine and lumbar puncture with 10 or 7.5 mg of hyperbaric bupivacaine thoracic puncture, all with 25 μg fentanyl until the sensory level reached T 3 . Intraoperative parameters, post-operative pain, complications, recovery, patient satisfaction, and cost were compared between both groups. Statistical Analysis Used: Means were compared by ANOVA or Kruskal-Wallis test, the percentages of the Chi-square test or Fisher′s exact test when appropriate. Time of motor and sensory block in spinal anesthesia group was compared by paired t test or Mann-Whitney test. Differences were considered significant when P ≤ 0.05, and for comparisons of mean pain visual scale, we employed the Bonferroni correction applied to be considered significant only with P ≤ 0.0125 Results: All procedures were completed under spinal anesthesia. The use of lidocaine 1% was successful in the prevention of shoulder pain in 329 (89% patients. There were significant differences in time to reach T 3 , obtaining 15 mg > 10 mg = 7.5 mg. There is a positive correlation between the dose and the incidence of hypotension. The lowest doses gave a decrease of 52.2% in the incidence of hypotension. There was a positive correlation between the dose and duration of sensory and motor block. Sensory block was almost twice the motor block at all doses. With low doses, 60% of patients went from table to stretcher

    Residency programs in anesthesiology in the United States struggle to balance the conflicting needs of formal didactic sessions, clinical teaching, and clinical service obligations. As a consequence of the explosion in knowledge about basic and applied sciences related to our specialty, residents and fellows are expected to make substantial efforts to supplement formal lectures with self-study. There is strong evidence to suggest that members of the younger generation use nontraditional methods to acquire information. Although training programs are not required to include topics related to history of anesthesia (HOA) in the didactic curriculum, and despite the fact that such knowledge does not directly impact clinical care, many programs include such lectures and discussions. We describe and discuss our experience with 3 alternate modalities of teaching HOA.First, we provide brief descriptions of HOA-related historical narratives and novels within the domain of popular literature, rather than those that might be considered textbooks. Second, we analyze content in movies and videodiscs dealing with HOA and determine their utility as educational resources. Third, we describe HOA tours to sites in close proximity to our institutions, as well as those in locations elsewhere in the United States and abroad.We suggest that informal HOA teaching can be implemented by every residency program without much effort and without taking away from the traditional curriculum. Participating in this unique and enriching experience may be a means of academic advancement. It is our hope and expectation that graduates from programs that incorporate such exposure to HOA become advocates of history and may choose to devote a part of their academic career toward exploration of HOA.

  9. Medication errors in anesthesia: unacceptable or unavoidable?

    Directory of Open Access Journals (Sweden)

    Ira Dhawan

    Full Text Available Abstract Medication errors are the common causes of patient morbidity and mortality. It adds financial burden to the institution as well. Though the impact varies from no harm to serious adverse effects including death, it needs attention on priority basis since medication errors' are preventable. In today's world where people are aware and medical claims are on the hike, it is of utmost priority that we curb this issue. Individual effort to decrease medication error alone might not be successful until a change in the existing protocols and system is incorporated. Often drug errors that occur cannot be reversed. The best way to ‘treat' drug errors is to prevent them. Wrong medication (due to syringe swap, overdose (due to misunderstanding or preconception of the dose, pump misuse and dilution error, incorrect administration route, under dosing and omission are common causes of medication error that occur perioperatively. Drug omission and calculation mistakes occur commonly in ICU. Medication errors can occur perioperatively either during preparation, administration or record keeping. Numerous human and system errors can be blamed for occurrence of medication errors. The need of the hour is to stop the blame - game, accept mistakes and develop a safe and ‘just' culture in order to prevent medication errors. The newly devised systems like VEINROM, a fluid delivery system is a novel approach in preventing drug errors due to most commonly used medications in anesthesia. Similar developments along with vigilant doctors, safe workplace culture and organizational support all together can help prevent these errors.

    The practice of anesthesia in war places significant restraints on the choice of anesthetic technique used; these include, but are not limited to, safety, simplicity, and portability. Ever since intravenous anesthesia became a practical alternative, there have been military doctors who felt that this technique was particularly suited to this environment. The challenge, as in civilian practice, has been to find the appropriate drugs as well as simple and safe delivery systems. The urgency of war has always stimulated innovation in medicine to counteract the ongoing development of weapons of war and their effects on the human body and to achieve improved survival as public expectations rise. This article traces the development of and the use of intravenous anesthesia by military physicians for battle casualties. The story starts long before the era of modern anesthesia, and the discussion concludes in the dog days of the cold war. The rapidly increasing interest in intravenous anesthesia in both civilian and military practice since the early 1990s is left for other authors to examine.

    Lessons learned over the past decade and a half of combat casualty management has brought about numerous advances in trauma anesthesia practice. In the post-Vietnam era, deployable anesthesia equipment centered on the capability to provide a balanced anesthetic technique, utilizing a combination of volatile gas and intravenous anesthetic adjuncts. The evolution of the modern battlefield has forced anesthesia providers across the military to adapt to mission requirements that often dictate a surgical capability that is more rapidly mobile and less reliant on logistical support. Institutional medical equipment development has focused on fielding a lighter, more mobile volatile gas delivery method. Despite numerous advances in anesthetic gas delivery, many veteran anesthesia providers have come to recognize the value of alternative anesthetic techniques in the deployed setting. One of the most appealing advances in combat anesthesia practice is the emergence of total intravenous anesthetics (TIVA) for trauma management and resuscitation. Although there have been numerous developments in anesthetic equipment for use in the deployed setting, TIVA has many advantages over volatile gas administration. Future research, development, and education should focus on TIVA and the ability to provide this as an alternative safe anesthetic for patients in austere environments. It is imperative to retain the lessons we have learned in order to adapt more effectively in future conflicts. This accumulation of knowledge must inform future innovative solutions to the challenges of casualty management in a deployed setting.

    A 31-year-old female, with 22 weeks of pregnancy, presented with sudden onset of severe headache. CT scan showed diffuse subarachnoid hemorrhage. A cerebral angiogram showed dissecting aneurysm of right cerebral artery. To obliterate the aneurysm and prevent rupture, the patient underwent coil embolization via an endovascular approach under general anesthesia because the procedure under sedation with local anesthesia was too risky for re-bleeding. The patient has been diagnosed as PAPA syndrome. Although the arthritis was now stable and she was taking no drug, remarkable osteoarthritis was observed. The cervical spine X ray demonstrated no cervical ankylosis. As patient was sedated with propofol, airway examination could not be done except noticing thyromental distance of seven centimeters. Patient's trachea was intubated using Macintosh size #3 laryngoscope blade and a 7.0 non-styletted tracheal tube at the first attempt without any problems (Cormack grade I). Anesthesia was maintained with sevoflurane, fentanyl and remifentanil. After the end of endovascular surgery, the patient was transferred to the intensive care unit under mechanical ventilation. She was weaned from mechanical ventilation 2 days later but consciousness was unclear. Right incomplete paralysis was also observed. MRI revealed vasospasm on the bilateral internal carotid artery. The patient underwent percutaneous tansluminalangioplasty coil and intraarterial injection of fasudil hydrochloride under local anesthesia. The consciousness recovered fully and the paralysis was improved. The patient delivered the baby by Caesarean sections under combined spinal and epidural anesthesia at 36 weeks without any problems with both the mother and baby.

    During the administration of anesthesia, the anesthesia provider has historically created a paper record, charted manually, that included extensive patient care–related data (vital signs, other parameters, etc) and commentaries. DocuSys, a proprietary anesthesia information management system (AIMS), creates an electronic version of the anesthesia record and provides additional information. It electronically captures data from clinical monitors and other sources, including scheduling applications and laboratory computers. The AIMS facilitates chart entries such as drug doses and case narratives. Benefits of an AIMS include improved legibility of the anesthesia record and greater efficiency in documentation efforts. Use of the AIMS assists the practitioner with decision support logic, such as the timing of antibiotic administration and the inclusion of legally required documentation. Upon case completion, the AIMS data are immediately available to other information systems, such as billing and medical records. Data can be made available from a single case or, more important, from thousands of cases to analyze variables such as efficiency of services, adherence to best practices, patient outcomes, and clinical research. The AIMS was deployed at the main campus of the Ochsner Health System on March 26, 2009. In this article, we discuss the issues involved in the AIMS implementation process: the successes, surprises, and continued challenges. PMID:21734847

    Objectives: To evaluate the influence of the ORM1 variants in codon 118 on the intra-operative remifentanil consumption under general anesthesia. Methods: A prospective gene association study, performed at the Jordan University Jordan, Amman, Jordan from September 2013 to August 2014. It includes patients who underwent septoplasty surgery under general anesthesia. All patients received standard intravenous anesthesia. Anesthesia maintained with fixed dose of Sevoflurane and variable dose of Remifentanil to keep the systolic blood pressure between 90-100 mm Hg. The Remifentanil dose was calculated and correlated with ORM1 genotype variance. Results: Genotype and clinical data were available for 123 cases. The A118A genotype was seen in 96 patients (78%), the A118G genotype was seen in 25 patients (20.3%), and only 2 patients had genotype G118G (1.6%). The G118G variant was removed from the statistical analysis due to small sample size. There was a significant effect of ORM1 genotype variant and the amount of remifentanil consumed. The A118A genotype received 0.173 ± 0.063 µg kg-1 min-1 and the A118G genotype received 0.316 ± 0.100 µg kg-1 min-1 (p<0.0001). Conclusion: The ORM1 gene has a role in intra-operative remifentanil consumption in patients who underwent septoplasty surgery under general anesthesia. The A118G gene required higher dose of remifentanil compared with the A118A genotype. PMID:28133690

  18. Laparoscopic hernioplasty with epidural anesthesia; a report of 20 patients

    2007-06-01

    Full Text Available Background: The incidence of inguinal hernia is 15 cases per 1,000 populations. The most common surgical methods of hernia repair are conventional open hernioplasty and laparoscopic hernioplasty. The advantages of laparoscopic hernioplasty are that the regional anatomy is observable, and bilateral herniorrhaphy can be performed at the same time. Since laparoscopic hernia is usually performed under general anesthesia, to shorten the length of hospital stay and to prevent complications, in this study, we evaluated the use of epidural anesthesia during hernioplasty. Methods: This study included 20 male patients treated by a single surgeon. We recorded the PCO2 levels before, during and after surgery, as well as the pain and intra-abdominal pressure. Results: Only one patient required conversion to general anesthesia. Three patients had hernia on the left side only, 14 patients on the right only and three patients had bilateral hernia. The PCO2 levels did not change (P=0.789. Fifty percent of patients had no postoperative pain. The median time to return to work or normal physical activity was 7 days. Conclusion: Laparoscopic inguinal herniorrhaphy is a feasible alternative to open surgical hernia repair. Employing epidural anesthesia prevents the complications of general anesthesia. This method achieves a shorter hospital stay and time to return to normal activity, as well as reduction in pain. Controlled trials comparing laparoscopic and tension-free open herniorrhaphy are needed to further assess the relative benefits of this procedure.

    Full Text Available BACKGROUND: Several epidemiological studies have been conducted to address the later effect of anesthesia on neurodevelopment in children. However, the results are still inconclusive. METHODS: We here conducted a systematic review and meta-analysis to summarize the currently available clinical and epidemiologic evidence on the association of anesthesia/surgery with neurodevelopmental outcomes in children by searching PubMed, EMBASE, and Web of Science database (from January-1 2000 to February-1, 2013. The evaluation of neurodevelopment includes language and learning disabilities, cognition, behavioral development, and academic performance. Both retrospective and prospective studies were included. Data were abstracted from seven eligible studies. We estimated the synthesized hazard ratios (HR and 95% confidence interval (CI according to inter-study heterogeneity. RESULTS: The pooled HR for the association of anesthesia/surgery with an adverse behavioral or developmental outcome was 1.25 (95% CI, 1.13-1.38, P<0.001; random-effects model in children undergoing the first anesthesia before the age of 4-year. Then we analyzed the factors for this association using meta-regression method. It showed that it was the number of times of exposure (HR = 1.75, 95% CI 1.31-2.33; P<0.001 rather than the time at exposure before 4-year (HR = 1.08, 95% CI 0.87-1.34 for the effect of per 1-year early exposure; P = 0.47 is a risk factor for neurodevelopmental impairment. CONCLUSION: The current clinical evidence suggests modestly elevated risk of adverse neurodevelopmental outcomes in children who were exposed to anesthesia/surgery during early childhood, especially for those with multiple times of exposure. Due to limitation of retrospective studies, prospective investigations are needed to determine whether anesthesia/surgery is causative.

    A modified technique is described for iontophoretic anesthesia in children who require myringotomy and insertion of a tube (tympanostomy). Principal modifications include the following procedures: (1) preoperative parenteral sedation; (2) relatively painless injection of lidocaine hydrochloride-epinephrine hydrochloride solution into the external auditory canal skin after iontophoresis alone to eliminate the extreme bony canal wall tenderness; (3) injection of lidocaine-epinephrine solution into an atelectatic middle ear to anesthetize the promontory for painless tube insertion; (4) substitution of a disposable ECG electrode for a metal plate electrode to eliminate the possibility of electrical burn from metal-to-skin contact. These modifications enhance the effectiveness and the safety of iontophoretic anesthesia, minimize the need for general anesthesia, and liberalize the indications for tympanostomy.

    The depth of anesthesia quantification has been one of the most research interests in the field of EEG signal processing and nonlinear dynamical analysis has emerged as a novel method for the study of complex systems in the past few decades. In this investigation we use the concept of nonlinear time series analysis techniques to reconstruct the attractor of anesthesia from EEG signal which have been obtained from different hypnotic states during surgery to give a characterization of the dimensional complexity of EEG by Correlation Dimension estimation. The dimension of the anesthesia strange attractor can be thought of as a measure of the degrees of freedom or the ;complexity' of the dynamics at different hypnotic levels. The results imply that for awaked state the correlation dimension is high, On the other hand, for light, moderate and deep hypnotic states these values decrease respectively; which means for anesthetized situation we expect lower correlation dimension.

    Total knee arthroplasty is associated with substantial postoperative pain that may impair mobility, reduce the ability to participate in rehabilitation, lead to chronic pain, and reduce patient satisfaction. Traditional general anesthesia with postoperative epidural and patient-controlled opioid analgesia is associated with an undesirable adverse-effect profile, including postoperative nausea and vomiting, hypotension, urinary retention, respiratory depression, delirium, and an increased infection rate. Multimodal anesthesia--incorporating elements of preemptive analgesia, neuraxial perioperative anesthesia, peripheral nerve blockade, periarticular injections, and multimodal oral opioid and nonopioid medications during the perioperative and postoperative periods--can provide superior pain control while minimizing opioid-related adverse effects, improving patient satisfaction, and reducing the risk of postoperative complications.

    It has been long recognized that anesthesia practice is profoundly based in physiology. With the advance of the technology of imaging, measurement and information, a serious gap has emerged between anesthesia mainly handling gross systemic parameters and molecular physiology. One of the main reasons is the lack of establishment of integration approach. This special series of reviews deals with systems physiology covering respiratory, cardiovascular, and nervous systems. It also includes metabolism, and fluid, acid-base, and electrolyte balance. Each review focuses on several physiological concepts in each area, explaining current understanding and limits of the concepts based on the new findings. They reaffirm the importance of applying physiological inference in anesthesia practice and underscore the needs of advancement of systems physiology.

Using dental needle for local anesthesia should be guided by the "one injection - one needle" rule, as a needle tends to deform by even the slightest contact with jawbone. Some of the shortcomings of carpule quality may be detected before use: signs of cup corrosion, the presence of sediment, air bubbles, rubber plunger disposition. In the case of such defects being identified all the package should not be used. The use of such carpule in clinical practice is unsafe.

    Creation of the American Society of Anesthesiologists Committee on Geriatric Anesthesia provided an opportunity for individuals to interact, strategize, and work with medical organizations outside of anesthesiology. These opportunities expanded with creation of the Society for the Advancement of Geriatric Anesthesia. The American Geriatrics Society provided a major boost when they realized it was important for surgical and related specialties to take an active role in the care of older patients. From this have come educational grants to improve residency training and establishment of a major research grant program now managed by the National Institutes of Health. Nevertheless, for improved care of the older patient, the level of involvement has to increase.

    Background: After spinal anesthesia, patients undergoing cesarean section are more likely to develop hemodynamic changes. The baricity of local anesthetic has an important role on spinal blockade effects. The aim of this study was to compare the isobar and hyperbaric bupivacaine 0.5% plus fentanyl on maternal hemodynamics after spinal anesthesia for C/S. Methods: In this double-blind study, 84 healthy pregnant women undergoing C/S using bupivacaine 0.5% isobar (study group, n=42) or hyperbaric (control group, n=42) for spinal anesthesia were scheduled. The study was conducted from 21 April 2014 to 21 November 2014 at Al-Zahra Hospital, Tabriz, Iran. Parameters such as maternal hemodynamics, block characteristics, side effects, and neonatal Apgar scores were recorded. Data were analyzed using the SPSS software by performing chi-square test, Fisher’s exact test, one-way ANOVA, Mann-Whitney U-test, and student’s t test. Results: The incidence of hypotension in the isobar group was lower than the hyperbaric group, although it was not statistically significant (40.47% vs. 61.9%, P=0.08). The duration of hypotension was shorter in the study group (1.6±7.8 min vs. 7.4±12.5 min, P=0.004). The dose of ephedrine was lower in the study group (2.4±6.6 mg vs. 5.3±10.7 mg, P=0.006). The main maternal side effect is sustained hypotension that was seen in 0 patients of the isobar and 7 (16.66%) of hyperbaric groups (P=0.006). None of the neonates had Apgar score≤7 at 5 min of delivery (P=1.0). Sensory and motor block duration was shorter in the study group (P=0.01). Conclusion: Isobaric bupivacaine is associated with more hemodynamic stability and shorter sensory and motor blockade in mothers under spinal anesthesia for C/S.

    Full Text Available The evolution of techniques and knowledge of beating heart surgery has led anesthesia toward the development of new procedures and innovations to promote patient safety and ensure high standards of care. Off-pump coronary artery bypass (OPCAB surgery has shown to have some advantages compared to on-pump cardiac surgery, particularly the reduction of postoperative complications including systemic inflammation, myocardial injury, and cerebral injury. Minimally invasive surgery for single vessel OPCAB through a limited thoracotomy incision can offer the advantage of further reduction of complications. The anesthesiologist has to deal with different issues, including hemodynamic instability and myocardial ischemia during aorto-coronary bypass grafting. The anesthesiologist and surgeon should collaborate and plan the best perioperative strategy to provide optimal care and ensure a rapid and complete recovery. The use of high thoracic epidural analgesia and fast-track anesthesia offers particular benefits in beating heart surgery. The excellent analgesia, the ability to reduce myocardial oxygen consumption, and the good hemodynamic stability make high thoracic epidural analgesia an interesting technique. New scenarios are entering in cardiac anesthesia: ultra-fast-track anesthesia with extubation in the operating room and awake surgery tend to be less invasive, but can only be performed on selected patients.

    Full Text Available Background. Xenon-in-oxygen is a high density gas mixture and may improve PaO2/FiO2 ratio in morbidly obese patients uniforming distribution of ventilation during anesthesia. Methods. We compared xenon versus sevoflurane anesthesia in twenty adult morbidly obese patients (BMI>35 candidate for roux-en-Y laparoscopic gastric bypass and assessed PaO2/FiO2 ratio at baseline, at 15 min from induction of anaesthesia and every 60 min during surgery. Differences in intraoperative and postoperative data including heart rate, systolic and diastolic pressure, oxygen saturation, plateau pressure, eyes opening and extubation time, Aldrete score on arrival to the PACU were compared by the Mann-Whitney test and were considered as secondary aims. Moreover the occurrence of side effects and postoperative analgesic demand were assessed. Results. In xenon group PaO2-FiO2 ratio was significantly higher after 60 min and 120 min from induction of anesthesia; heart rate and overall remifentanil consumption were lower; the eyes opening time and the extubation time were shorter; morphine consumption at 72 hours was lower; postoperative nausea was more common. Conclusions. Xenon anesthesia improved PaO2/FiO2 ratio and maintained its distinctive rapid recovery times and cardiovascular stability. A reduction of opioid consumption during and after surgery and an increased incidence of PONV were also observed in xenon group.

    Full Text Available Alexander R Facque, Peter J Taub Division of Plastic and Reconstructive Surgery, Department of Surgery, Mount Sinai Medical Center, New York, NY, USA Abstract: In 2013, there were 17 million procedures performed by plastic and reconstructive surgeons in the United States in the private office or ambulatory “surgicenter” setting, as well as additional operations performed in hospitals on an outpatient basis. As interest in performing increasingly complex surgical procedures on an outpatient basis continues to grow, the surgeon and anesthesiologist alike must be prepared to offer safe and reliable anesthesia and analgesia in the ambulatory setting. Surgeons must be aware of the possible techniques that will be employed in their surgeries in order to anticipate and prepare patients for possible postoperative side effects, and anesthesiologists must be prepared to offer such techniques in order to ensure a relatively rapid return to normal activity despite potentially having undergone major surgery. The following is a review of the specific considerations that should be given to ambulatory plastic surgery patients with comments on recent developments in the techniques used to safely administer agreeable and effective anesthesia.

    Full Text Available PURPOSE: The aim of this study was to evaluate the effect of dexmedetomidine on shivering during spinal anesthesia. METHODS: Sixty patients (American Society of Anesthesiologists physical status I or II, aged 18-50 years, scheduled for elective minor surgical operations under spinal anesthesia with hyperbaric bupivacaine, were enrolled. They were administered saline (group C, n = 30 or dexmedetomidine (group D, n = 30. Motor block was assessed using a Modified Bromage Scale. The presence of shivering was assessed by a blinded observer after the completion of subarachnoid drug injection. RESULTS: Hypothermia was observed in 21 patients (70% in group D and in 20 patients (66.7% in group C (p = 0.781. Three patients (10% in group D and 17 patients (56.7% in group C experienced shivering (p = 0.001. The intensity of shivering was lower in group D than in group C (p = 0.001. Time from baseline to onset of shivering was 10 (5-15 min in group D and 15 (5-45 min in group C (p = 0.207. CONCLUSION: Dexmedetomidine infusion in the perioperative period significantly reduced shivering associated with spinal anesthesia during minor surgical procedures without any major adverse effect during the perioperative period. Therefore, we conclude that dexmedetomidine infusion is an effective drug for preventing shivering and providing sedation in patients during spinal anesthesia.

    Despite mixed results regarding the clinical utility of checklists, the anesthesia community is increasingly interested in advancing research around this important topic. Although several checklists have been developed to address routine perioperative care, few checklists in the anesthesia literature specifically target the management of trauma patients. We adapted a recently published "trauma and emergency checklist" for the initial phase of resuscitation and anesthesia of critically ill trauma patients into an applicable perioperative cognitive aid in the form of a pictogram that can be downloaded by the medical community. The Ryder Cognitive Aid Checklist for Trauma Anesthesia is a letter-sized, full-color document consisting of 2 pages and 5 sections. This cognitive aid describes the essential steps to be performed: before patient arrival to the hospital, on patient arrival to the hospital, during the initial assessment and management, during the resuscitation phase, and for postoperative care. A brief online survey is also presented to obtain feedback for improvement of this tool. The variability in utility of cognitive aids may be because of the specific clinical task being performed, the skill level of the individuals using the cognitive aid, overall quality of the cognitive aid, or organizational challenges. Once optimized, future research should be focused at ensuring successful implementation and customization of this tool.

    Full Text Available Introduction: Hearing loss after surgery is reported rarely. Its prevalence rate is different and reported to be between 3-92%. Hearing loss is often subclinical and not diagnosed without audiometry. The aim of this study was to determine rate of hearing changes after spinal anesthesia in patients undergoing surgery with spinal anesthesia. Methods: In this descriptive study, forty male patients scheduled for repair of inguinal hernia under spinal anesthesia were selected by simple sampling method. Before surgery, audiometry was performed for both the ears of the patients. Audiomatery was performed again by the audiometry specialist on day one, five, fifteen and two months after surgery. Results: Hearing loss was observed in 13 (32.5% patients. Hearing loss in 12 patients (92% was in low hearing frequency range and 1 patient (8% was in mid hearing frequency. Hearing loss in 8 patients (61% was ipsilateral and in 5 patients (39% was bilateral. Hearing loss in 9 patients (69% on 5th day and 2 patients (5/15% on 15th day resolved spontaneously. Conclusion: Results of this study conformed that hearing loss after spinal anesthesia is not a serious problem and can resolve spontaneously. It seems that there is relationship between hearing loss and headache.

    Full Text Available Ushma Shah, David T Wong, Jean Wong Department of Anesthesia, Toronto Western Hospital, University Health Network, University of Toronto, Toronto, ON, Canada Abstract: Most surgeries in North America are performed on an ambulatory basis, reducing health care costs and increasing patient comfort. Patient satisfaction is an important outcome indicator of the quality of health care services incorporated by the American Society of Anesthesiologists (ASA. Patient satisfaction is a complex concept that is influenced by multiple factors. A patient's viewpoint and knowledge plays an influential role in patient satisfaction with ambulatory surgery. Medical optimization and psychological preparation of the patient plays a pivotal role in the success of ambulatory surgery. Postoperative pain, nausea, and vomiting are the most important symptoms for the patient and can be addressed by multimodal drug regimens. Shared decision making, patient–provider relationship, communication, and continuity of care form the main pillars of patient satisfaction. Various psychometrically developed instruments are available to measure patient satisfaction, such as the Iowa Satisfaction with Anesthesia Scale and Evaluation du Vecu de I'Anesthesie Generale, but none have been developed specifically for ambulatory surgery. The ASA has made recommendations for data collection for patient satisfaction surveys and emphasized the importance of reporting the data to the Anesthesia Quality Institute. Future research is warranted to develop a validated tool to measure patient satisfaction in ambulatory surgery. Keywords: patient, satisfaction, anesthesia, outcomes, questionnaire, perspectives

    Full Text Available This work presents a case of a pregnant female dog, of English bulldog breed, three years old, which was brought to Belgrade Faculty of Veterinary Medicine because of inability for normal parturition. Cesarean section is an urgent intervention both in human and in veterinary medicine. Anesthesia of a pregnant dog should be carried out very carefully, because of all the physiological changes that appear during pregnancy, as well as the impact of anesthetics on embryos themselves. Anesthetics, analgesics and sedatives pass through blood brain barrier, but also their transport goes through placenta to embryo, so for that reason it is not possible to anesthetize only mother and to avoid anesthesia effects on the embryo. Therefore, anesthetics with short time of action which metabolize quickly and have minimal negative effect on embryos are recommended. When choosing the right analgesics and anesthetics, there should be known that female dogs in which it is necessary to do Cesarean section belong to the group of high risk patients. Pregnant female dogs are exposed to hypoventilation, hypoxia, hypercapnia, intense heart work, vomiting and regurgitation as well. Reversible anesthetics are recommended to provide shorter duration time of anesthesia, and in accordance, inhalation anesthetics doses are minimal. Application of α2- agonist in premedication, propophol in induction, as well as maintaining general inhalation anesthesia with sevofluran, along with local analgesia, proved to be the ideal combination in this case of cesarean section.

    Fewer than 5% of anesthesia departments use an electronic medical record (EMR) that is anesthesia specific. Many anesthesia information management systems (AIMS) have been developed with a focus only on the unique needs of anesthesia providers, without being fully integrated into other electronic health record components of the entire enterprise medical system. To understand why anesthesia providers should embrace health information technology (HIT) on a health system-wide basis, this article reviews recent HIT history and reviews HIT concepts. The author explores current developments in efforts to expand enterprise HIT, and the pros and cons of full enterprise integration with an AIMS.

    Full Text Available Anesthesia in a dwarf patient may be challenging as various anatomical anomalies make both general and regional anesthesia difficult. These patients may have atlantoaxial instability, potential for airway obstruction, and associated respiratory problems that may pose problems for general anesthesia. Spinal stenosis, osteophytes, short pedicles, or a small epidural space could complicate regional anesthesia in dwarfs which could lead to difficulties in locating the epidural space and increase the risk of dural puncture. Spinal stenosis may impair cerebrospinal fluid flow such that identification of dural puncture is difficult. This elderly dwarf patient had history of bronchial asthma with restriction of neck extension, managed successfully using combined spinal–epidural anesthesia.

    Functional magnetic resonance imaging (fMRI) has revolutionized neuroscience by opening a unique window that allows neurocircuitry function and pathological alterations to be probed non-invasively across brain disorders. Here we report a novel sustainable anesthesia procedure for small animal neuroimaging that overcomes shortcomings of anesthetics commonly used in rodent fMRI. The significantly improved preservation of cerebrovascular dynamics enhances sensitivity to neural activity changes for which it serves as a proxy in fMRI readouts. Excellent cross-species/strain applicability provides coherence among preclinical findings and is expected to improve translation to clinical fMRI investigations. The novel anesthesia procedure based on the GABAergic anesthetic etomidate was extensively validated in fMRI studies conducted in a range of genetically engineered rodent models of autism and strains commonly used for transgenic manipulations. Etomidate proved effective, yielded long-term stable physiology with basal cerebral blood flow of ~0.5 ml/g/min and full recovery. Cerebrovascular responsiveness of up to 180% was maintained as demonstrated with perfusion- and BOLD-based fMRI upon hypercapnic, pharmacological and sensory stimulation. Hence, etomidate lends itself as an anesthetic-of-choice for translational neuroimaging studies across rodent models of brain disorders.

    Patients with multiple trauma presenting with apnea or a gasping breathing pattern (respiratory rate traumatic brain injury [Glasgow Coma Scale (GCS)29/min). The induction of anesthesia after preoxygenation is conducted as rapid sequence induction (analgesic, hypnotic drug, neuromuscular blocking agent). With the availability of ketamine as a viable alternative, the use of etomidate is not encouraged due to its side effects on adrenal function. An electrocardiogram (ECG), blood pressure measurement and pulse oximetry are needed to monitor the emergency anesthesia and the secured airway. Capnography is absolutely mandatory to confirm correct placement of the endotracheal tube and to monitor tube dislocations as well as ventilation and oxygenation in the prehospital and hospital setting. Because airway management is often complicated in trauma patients, alternative devices and a fiber-optic endoscope need to be available within the hospital. Use of these alternative measures for airway management and ventilation should be considered at the latest after a maximum of three unsuccessful intubation attempts. Emergency medical service (EMS) physicians should to be trained in emergency anesthesia, ETI and alternative methods of airway management on a regular basis. Within hospitals ETI, emergency anesthesia and ventilation are to be conducted by trained and experienced anesthesiologists. When a difficult airway or induction of anesthesia is expected, endotracheal intubation should be supervised or conducted by an anesthesiologist. Normoventilation should be the goal of mechanical ventilation. After arrival in the resuscitation room the ventilation will be controlled and guided with the help of arterial blood gas analyses. After temporary removal of a cervical collar, the cervical spine needs to be immobilized by means of manual in-line stabilization when securing the airway.

    Full Text Available Background: The assessment of the anesthesia course in our university comprises Objective Structured Clinical Examinations (OSCEs, in conjunction with portfolio and multiple-choice questions (MCQ. The objective of this study was to evaluate the outcome of different forms of anesthesia course assessment among 5 th year medical students in our university, as well as study the influence of gender on student performance in anesthesia. Methods: We examined the performance of 154, 5 th year medical students through OSCE, portfolios, and MCQ. Results: The score ranges in the portfolio, OSCE, and MCQs were 16-24, 4.2-28.9, and 15.5-44.5, respectively. There was highly significant difference in scores in relation to gender in all assessments other than the written one (P=0.000 for Portfolio, OSCE, and Total exam, whereas P=0.164 for written exam. In the generated linear regression model, OSCE alone could predict 86.4% of the total mark if used alone. In addition, if the score of the written examination is added, OSCE will drop to 57.2% and the written exam will be 56.8% of the total mark. Conclusions: This study demonstrates that different clinical methods used to assess medical students during their anesthesia course were consistent and integrated. The performance of female was superior to male in OSCE and portfolio. This information is the basis for improving educational and assessment standards in anesthesiology and for introducing a platform for developing modern learning media in countries with dearth of anesthesia personnel.

    Full Text Available Daniela Ghisi, Stefano Bonarelli Department of Anaesthesia and Postoperative Intensive Care, Istituto Ortopedico Rizzoli, Bologna, Italy Abstract: Spinal anesthesia is a reliable and safe technique for procedures of the lower extremities. Nevertheless, some of its characteristics may limit its use for ambulatory surgery, including delayed ambulation, risk of urinary retention, and pain after block regression. The current availability of short-acting local anesthetics has renewed interest for this technique also in the context of short- and ultra-short procedures. Chloroprocaine (CP is an amino-ester local anesthetic with a very short half-life. It was introduced and has been successfully used for spinal anesthesia since 1952. Sodium bisulfite was then added as a preservative after 1956. The drug was then abandoned in the 1980s for several reports of neurological deficits in patients receiving accidentally high doses of intrathecal CP during epidural labor analgesia. Animal studies have proven the safety of the preservative-free formulation, which has been extensively evaluated in volunteer studies as well as in clinical practice with a favorable profile in terms of both safety and efficacy. In comparison with bupivacaine, 2-chloroprocaine (2-CP showed faster offset times to end of anesthesia, unassisted ambulation, and discharge from hospital. These findings suggests that 2-CP may be a suitable alternative to low doses of long-acting local anesthetics in ambulatory surgery. Its safety profile also suggests that 2-CP could be a valid substitute for intrathecal short- and intermediate-acting local anesthetics, such as lidocaine and mepivacaine – often causes of transient neurological symptoms. In this context, literature suggests a dose ranging between 30 and 60 mg of 2-CP for procedures lasting 60 minutes or less, while 10 mg is considered the no-effect dose. The present review describes recent evidence about 2-CP as an anesthetic agent for

    Clinical pattern of anesthesia, hemodynamic and gas exchange states were evaluated in 64 patients with congenital or acquired damage of maxillary-facial region due to tumor or trauma. 51 patients were intubated under locoregional anesthesia of the upper respiratory tract (superior laryngeal nerves, glossopharyngeal nerves, intratracheal anesthesia) by means of blind nasal or oral fiberoptic retrograde and by using laryngeal mask technique. In 12 cases fiberoptic device was used for intubation under local anesthesia by lidocaine solution. There was no airways obstruction in any case. Satisfactory anesthesia in oropharynx, larynx and trachea was reached in all cases, the most profound blockage of airways and lack of pharyngeal and laryngeal reflexes being in patients under locoregional anesthesia. So locoregional anesthesia can be used for awake intubation.

    Neonates with inguinal hernia face a relatively high risk of incarcerated hernia and bowel obstruction and this therefore requires surgical treatment. Complications following general anesthesia even for minor surgery are more common in low birth weight neonates than in term neonates. Caudal epidural anesthesia without adjunct general anesthesia has been recommended for neonates to reduce the risk of postoperative complications. The successful application of awake caudal anesthesia with levobupivacaine for inguinal hernia repair in 15 low birth weight neonates is reported. Single dose caudal epidural anesthesia was administered for inguinal hernia surgery to avoid complications associated with general anesthesia. Caudal block was performed with 2.5 mg/kg body weight (BW) levobupivacaine. Caudal anesthesia can be recommended as an effective technique for avoiding postoperative anesthetic complications in low birth weight neonates.

    Use of an anesthesia information management system (AIMS) has been reported to improve accuracy of recorded information. We tested the hypothesis that analyzing the distribution of times charted on paper and computerized records could reveal possible rounding errors, and that this effect could be modulated by differences in the user interface for documenting certain event times with an AIMS. We compared the frequency distribution of start and end times for anesthesia cases completed with paper records and an AIMS. Paper anesthesia records had significantly more times ending with "0" and "5" compared to those from the AIMS (p distribution of minutes recorded with AIMS was almost evenly distributed, unlike those from paper records that still showed significant end-digit preference. The accuracy of anesthesia case start times and case end times, as inferred by statistical analysis of the distribution of the times, is enhanced with the use of an AIMS. Furthermore, the differences in AIMS user interface for documenting case start and case end times likely affects the degree of end-digit preference, and likely accuracy, of those times.

    Full Text Available ABSTRACT BACKGROUND AND OBJECTIVES: The use of neuraxial anesthesia in cardiac surgery is recent, but the hemodynamic effects of local anesthetics and anticoagulation can result in risk to patients. OBJECTIVE: To review the benefits of neuraxial anesthesia in cardiac surgery for CABG through a systematic review of systematic reviews. CONTENT: The search was performed in Pubmed (January 1966 to December 2012, Embase (1974 to December 2012, The Cochrane Library (volume 10, 2012 and Lilacs (1982 to December 2012 databases, in search of articles of systematic reviews. The following variables: mortality, myocardial infarction, stroke, in-hospital length of stay, arrhythmias and epidural hematoma were analyzed. CONCLUSIONS: The use of neuraxial anesthesia in cardiac surgery remains controversial. The greatest benefit found by this review was the possibility of reducing postoperative arrhythmias, but this result was contradictory among the identified findings. The results of findings regarding mortality, myocardial infarction, stroke and in-hospital length of stay did not show greater efficacy of neuraxial anesthesia.

    Full Text Available Background: Total Intravenous Anesthesia (TIVA compared to general anesthesia has some pits and falls. Many drugs have been employed for this anesthesia. Propofol is accounted as the last advent anesthetic drug. It belongs to alkyl phenol families and has been accounted one of the best choices for the continuous infusion. Invention of midazolam as the first water soluble benzodiazepine was also an important event in anesthesia and it can be used as continuous infusion for the anesthesia. Materials and Methods: In this randomized controlled clinical trial, alfentanyl plus propofol or midazolam were used for TIVA anesthesia in 60 female patients undergoing Dilatation and Curettage (D&C in Dr.Shariati hospital in March 2002 till March 2003. They were allocated reandomly in two group of alfentanyl plus propofol (propofol group or alfentanyl plus midazolam (midazolam group Results: There was no significant difference in mean of age between propofol group and midazolam group (P>0.05, also There was no significant difference in preanesthesia condition such as blood pressure and heart rate between propofol group and midazolam group (p>0.05. After induction of anesthesia there was a gross blood pressure decrease in both group that it was greater in midazolam group (85 mmHg versus 73 mmHg, P0.05 also there was just one naloxane injection in midazolam group that have no significant difference between groups (P>0.05. Recovery room stay was significantly lower in propofol group (25 minutes versus 39 minutes, P<0.05. Conclusion: The results of this study was similar to Vuyk et.al.In their study there was a significant lower recovery time estimated by psychomotor reflexes and there was significant lower drowsiness, place and time orientation time compared to midazolam group. Finally according to the results of this study it can be resulted that TIVA with propofol is more suitable than midazolam and it can lower hospitalization time and cost. In future studies

    Full Text Available Introduction, definition, rationale and scope: Dermatosurgery and Cosmetic dermatology procedures are being performed by increasing number of dermatologists. Most dermatosurgeries are performed in an outpatient setting and as day care surgeries, under local anesthesia. Hence, it is important to improve patient comfort during all procedures. These guidelines seek to lay down directives in the use of local anesthesia, outline the different local anesthetics, the mode of administration, complications arising out of such procedure and management of the same. Facility for administration of local anesthesia: Local anesthesia is usually administered in the dermatologist′s procedure room. The room should be equipped to deal with any emergencies arising from administration of local anesthesia. Qualifications of local anesthesia administrator: Local anesthesia administrator is a person who applies or injects local anesthetic agent for causing analgesia. Procedures done under local anesthesia are classified as Level I office procedures and require the administrator to have completed a course in Basic Cardiac Life Support (BCLS. Evaluation of patients for topical or infiltrative anesthesia: Details of patient′s past medical history and history of medications should be noted. Allergy to any medications should be specifically enquired and documented. Patients for tumescent anesthesia need additional precautions to be observed as described in these guidelines. Methods of administration of local anesthesia: Different methods include topical anesthesia, field block, ring block, local infiltration and nerve block. Also, it includes use of local anesthetics for anesthetizing oral and genital mucosa. Tumescent anesthesia is a special form of local anesthesia used in liposuction and certain selected procedures. Local anesthetic agents: Different local anesthetics are available such as lignocaine, prilocaine, bupivacaine. The dermatologist should be aware of the

    Full Text Available Introduction: A restricted sympathetic block during spinal anesthesia may minimize hemodynamic changes. This prospective randomized study compared unilateral and bilateral spinal anesthesia with respect to the intra- and postoperative advantages and complications of each technique. Material and methods: Spinal anesthesia was induced with 0.5% hyperbaric bupivacaine and a 25-G Quincke needle (Dr. J in two groups of patients with physical status ASA I-II who had been admitted for orthopedic surgeries. In group A, dural puncture was performed with the patient in a seated position using 2.5 cm3 of hyperbaric bupivacaine. Each patient was then placed in the supine position. In group B, dural puncture was performed with the patient in the lateral decubitus position with 1.5 cm3 of hyperbaric bupivacaine. The lower limb was the target limb. The speed of injection was 1 mL/30 s, and the duration of time spent in the lateral decubitus position was 20 min. Results: The demographic data were similar in both groups. The time to the onset of the sensory and motor block was significantly shorter in group A (p = 0.00. The duration of motor and sensory block was shorter in group B (p < 0.05. The success rate for unilateral spinal anesthesia in group B was 94.45%. In two patients, the spinal block spread to the non-dependent side. The incidence of complications (nausea, headache, and hypotension was lower in group B (p = 0.02. Conclusion: When unilateral spinal anesthesia was performed using a low-dose, low-volume and low-flow injection technique, it provides adequate sensory-motor block and helps to achieve stable hemodynamic parameters during orthopedic surgery on a lower limb. Patients were more satisfied with this technique as opposed to the conventional approach. Furthermore, this technique avoids unnecessary paralysis on the non-operated side.

    Full Text Available Many studies have evaluated risk factors associated with complications after free flap surgery, but these studies did not evaluate the impact of anesthesia management. The goal of the current study was to evaluate the differences between patients who received inhalation and total intravenous anesthesia (TIVA in free flap surgery.One hundred and fifty-six patients who underwent free flap surgery for head and neck cancer were retrospectively divided into the TIVA (96 patients and the inhalation group (87 patients. Perioperative hemodynamic data and postoperative medical complications were determined by documented medical records.Ninety-six patients in the TIVA group were compared with 87 patients who received inhalation anesthesia. There were no differences in gender, age, classification of physical status based on American Society for Anesthesiologists (ASA score, and cormobidities between the two groups. Patients in the TIVA group required less perioperative crystalloid (4172.46 ± 1534.95 vs. 5183.91 ± 1416.40 ml, p < 0.0001 and colloid (572.46 ± 335.14 vs. 994.25 ± 434.65 ml, p < 0.0001 to maintain hemodynamic stability. Although the mean anesthesia duration was shorter in the TIVA group (11.02 ± 2.84 vs. 11.70± 1.96 hours, p = 0.017, the blood loss was similar between groups (p = 0.71. There was no difference in surgical complication rate, but patients in the TIVA group developed fewer pulmonary complications (18 vs. 47, p = 0.0008. After multivariate regression, patients in the TIVA group had a significantly reduced risk of pulmonary complication compared with the inhalation group (Odds ratio 0.41, 95% CI 0.18-0.92.Total intravenous anesthesia was associated with significantly fewer pulmonary complications in patients who received free flap reconstruction.

    Full Text Available Abstract: The aim of this study was to assess the cardiopulmonary effects, the onset time after the administration of a detomidine/ketamine combination, and the recovery from anesthesia of cougars (Puma concolor anesthetized with detomidine/ketamine and isoflurane or sevoflurane for abdominal ultrasound imaging. Fourteen animals were randomly allocated into two experimental groups: GISO (n=7 and GSEVO (n=7. Chemical restraint was performed using 0.15mg/kg detomidine combined with 5mg/kg ketamine intramuscularly; anesthesia induction was achieved using 2mg/kg propofol intravenously and maintenance with isoflurane (GISO or sevoflurane (GSEVO. The following parameters were assessed: heart rate, respiratory rate, systolic and diastolic arterial blood pressure, mean arterial blood pressure, oxyhemoglobin saturation, rectal temperature, central venous pressure, and end-tidal carbon dioxide. The time to sternal recumbency (TSR and time to standing position (TSP were also determined. There was not statistically significant difference for the cardiopulmonary variables or TSP whereas TSR was significantly shorter in GSEVO. The time to onset of anesthesia was 11.1±1.2 minutes and 11.3±1.8 minutes for GISO and GSEVO, respectively. The anesthesia of cougars with detomidine/ketamine and isoflurane or sevoflurane was conducted with safety, cardiopulmonary stability, and increased time to sternal recumbency in the GISO group.

    Full Text Available OBJECTIVE: We aim to compare selective spinal anesthesia and general anesthesia with regard to postoperative recovery and fast-track eligibility in day surgeries. MATERIALS AND METHOD: Sixty geriatric outpatient cases, with ASA II-III physical status and requiring shortduration transurethral intervention, were enrolled in the study. The cases were split into 2 groups: as general anesthesia (Group GA and selective spinal anesthesia (Group SSA. Group GA (n = 30 received propofol 2 mg kg-1 (until loss of eyelash reflex, remifentanil induction 0.5-1 µg kg-1, and laryngeal mask. Maintenance was achieved by 4-6% desflurane in 60% N2O and 40% O2 along with remifentanil infusion at 0.05 µg /kg-1 /min-1. Drugs were discontinued after the withdrawal of the ureteroscope, and extubation was carried out with 100% O2. Group SSA (n = 30 received 0.5% spinal anesthesia via L4-5 space by 0.5% hyperbaric bupivacaine 5 mg. Anesthesia preparation time, time to surgical anesthesia level, postoperative fast-tracking, and time to White-Song recovery score of 12, were noted. In the operating room, we evaluated hemodynamics, nausea/vomiting, surgeon and patient satisfaction with anesthesia, perioperative midazolam-fentanyl administration, postoperative pain, and discharge time. RESULTS: Anesthesia preparation time, length of surgery, anesthesia-related time in the operating room, time to sit, and time to walk were significantly low in Group GA (p < 0.05, whereas time to fast-track eligibility, length of stay in the PACU, discharge time, and other parameters were similar in both of the groups. CONCLUSION: While anesthesia preparation time, length of surgery, start time of surgery, time to sit, and time to walk were shorter in the General Anesthesia group, time to fast-track eligibility, phase 1 recovery time, and discharge time were similar among patients subjected to selective spinal anesthesia.

    Stiff Person Syndrome (SPS), typified by rigidity in muscles of the torso and extremities and painful episodic spasms, is a rare autoimmune-based neurological disease. Here we present the successful endotracheal intubation and application of TIVA without muscle relaxants on an SPS patient. A 46 years old male patient was operated with ASA-II physical status because of lumber vertebral compression fracture. After induction of anesthesia using lidocaine, propofol and remifentanil tracheal intubation was completed easily without neuromuscular blockage. Anesthesia was maintained with propofol, remifentanil and O2/air mixture. After a problem-free intraoperative period the patient was extubated and seven days later was discharged walking with aid. Though the mechanism is not clear neuromuscular blockers and volatile anesthetics may cause prolonged hypotonia in patients with SPS. We think the TIVA technique, a general anesthetic practice which does not require neuromuscular blockage, is suitable for these patients.

    Throughout its history, anesthesia and critical care medicine has experienced vast improvements to increase patient safety. Consequently, anesthesia has never been performed on such a high level as it is being performed today. As a result, we do not always fully perceive the risks involved in our daily activity. A survey performed in Swiss hospitals identified a total of 169 hot spots which endanger patient safety. It turned out that there is a complex variety of possible errors that can only be tackled through consistent implementation of a safety culture. The key elements to reduce complications are continuing staff education, algorithms and standard operating procedures (SOP), working according to the principles of crisis resource management (CRM) and last but not least the continuous work-up of mistakes identified by critical incident reporting systems.

    From October 1991 through April 1992, 16 infants aged 5 to 25 months (mean age 14.3 months) underwent bronchoscopy with a flexible fiberoptic bronchoscope, under local anesthesia. The technique is described in detail. Reasons for bronchoscopy included recurrent or persistent pneumonia (n = 4), persistent atelectasia (n = 4), lymphadenopathy and/or airway compression (n = 2), suspected foreign body (n = 2), bronchoalveolar lavage to investigate diffuse interstitial lung disease (n = 2), and severe recurrent wheezing (n = 2). The procedure established the accurate diagnosis in 14 cases. Adverse events (32%) were minor (transient hypoxia, n = 3; moderate fever, n = 1; and laryngospasm, n = 1) and resolved completely. Flexible fiberoptic bronchoscopy under local anesthesia is a simple procedure which is safe in patients under 30 months of age when performed by a experienced operator in an adequate facility. This method is useful for the diagnosis and/or treatment of a broad spectrum of conditions.

    A 7-month-old Quarter Horse filly was admitted for surgical repair of a right olecranon fracture. Anesthesia was achieved with xylazine hydrochloride, guaifenesin, ketamine hydrochloride, and halothane. Two and a half hours after induction of anesthesia, myotonia, muscle fasciculations, and sweating, concurrent with high serum potassium concentration and associated electrocardiographic changes consistent with hyperkalemic periodic paralysis, were observed. Treatment included intermittent positive-pressure ventilation, changing intravenous administration of fluids from lactated Ringer's solution to 0.9% NaCl solution, and administration of calcium gluconate, glycopyrrolate, dopamine, and sodium bicarbonate. Clinical signs resolved with the return of serum potassium concentrations to the reference range. The horse was confirmed to be heterozygous for hyperkalemic periodic paralysis by DNA testing.

    Patient safety has become an important aspect of national health care initiatives. The purpose of this evaluation was to measure the impact of a patient safety education series for students enrolled in a nurse anesthesia program. Baseline surveys that measured patient safety competencies across three domains, attitudes, skills and knowledge, were administered to the students. A patient safety education series was delivered to the cohort and the survey was then readministered. Mean scores were compared using independent samples t tests. Attitude scores did not change from baseline to posttest. Participants scored higher on posttest means for both the patient safety skills and knowledge domains. Incorporating patient safety content into the nurse anesthesia master's degree curriculum may enhance clinicians' skills and knowledge related to patient safety, and the addition of a patient safety curriculum is important during the formative education process.

    Full Text Available Labetalol, a combined alfa and beta-adrenergic receptor antagonist, is used as an antihypertensive drug. We report a case of an acute rise in blood pressure and lower limb pain due to the inadvertent intrathecal administration of labetalol, mistaking it for bupivacaine, during obstetric anesthesia. The situation was rescued by converting to general anesthesia. The cesarean delivery was uneventful, and mother as well as newborn child showed no ill-effect. This particular medication error was attributable to a failure on the part of the doctors administering the injection to read and cross-check medication labels and the practice of keeping multiple injections together. In the absence of an organized medication error reporting system and action on that basis, such events may recur in future.

  6. Nerves and Anesthesia: A physics perspective on medicine

    CERN Document Server

    Heimburg, Thomas

    2014-01-01

    We present a recent theory for nerve pulse propagation and anesthesia and argue that both nerve activity and the action of anesthetics can be understood on the basis of simple physical laws. It was found experimentally that biological membranes melt from a solid state to a liquid state just below physiological temperature. Such melting processes have a profound influence on the physical properties of cell membranes. They make it possible for mechanical pulses (solitons) to travel along nerve axons. In these pulses, a region of solid phase travels in the liquid nerve membrane. These pulses display many properties associated with the action potential in nerves. Both general and local anesthetics lower melting temperatures of membranes. Thus, they make it more difficult to excite the nerve membrane. Since hydrostatic pressure increases melting temperatures, it counteracts anesthesia. This theory has the virtue of providing a simple explanation of the famous Meyer-Overton correlation, which states that the effect...

    Full Text Available Management of successful pregnancy after renal transplantation is a unique challenge to nephrologist, obstetrician, and anesthesiologist, as these patients have altered physiology and are immune-compromised. We present the anesthetic management of three postrenal transplant patients scheduled for cesarean section. While conducting such cases, cardiovascular status, hematological status, and function of transplanted kidney should be assessed thoroughly. Side effects of immunosuppressant drugs and their interaction with anesthetic agents should be taken into consideration.

  10. Exposure to ketamine anesthesia affects rat impulsive behavior

    Directory of Open Access Journals (Sweden)

    António Melo

    2016-11-01

    Full Text Available Introduction: Ketamine is a General Anesthetic that activates several neurotransmitter pathways in various part of the brain. The acute effects as general anesthetic are the most well-known and sought-after: to induce loss of responsiveness and to produce immobility during invasive procedures. However, there is a concern that repeated exposure might induce behavioral changes that could outlast their acute effect. Most research in this field describes how GA affects cognition and memory. Our work is to access if general anesthesia with ketamine can disrupt the motivational behaviour trait, more specifically measuring impulsive behaviour.Methods: With the aim to evaluate the effects of exposure to repeat anesthetic procedures with ketamine in motivational behavior, we tested animals in a paradigm of impulsive behavior, the Variable Delay-to-Signal (VDS. In addition, accumbal and striatal medium spiny neurons morphology was assessed. Results: Our results demonstrated that previous exposure to ketamine deep-anesthesia affects inhibitory control (impulsive behavior. Specifically, ketamine exposed animals maintain a subnormal impulsive rate in the initial periods of the delays. However, and in longer delays while control animals progressively refrain their premature unrewarded actions, ketamine-exposed animals show a different profile of response with higher premature unrewarded actions in the last seconds. Animals exposed to multiple ketamine anesthesia also failed to show an increase in premature unrewarded actions between the initial and final periods of 3s delays. These behavioral alterations are paralleled by an increase in dendritic length of medium spiny neurons of the nucleus accumbens.Conclusions: This demonstrates that ketamine anesthesia acutely affects impulsive behavior. Interestingly, it also opens up the prospect of using ketamine as an agent with the ability to modulate impulsivity trait.

    The mechanical ventilation of horses during anesthesia remains a crucial option for optimal anesthetic management, if the possible negative cardiovascular side effects are managed, because this species is prone to hypercapnia and hypoxemia. The combined use of capnography and pitot-based spirometry provide complementary information on ventilation and respiratory mechanics, respectively. This facilitates management of mechanical ventilation in conditions of changing respiratory system compliance (ie, laparoscopy) and when investigating new ventilatory strategies including alveolar recruitment maneuvers and optimization of positive expiratory pressure.

To the authors' knowledge, it has never before been reported following an ocular surgery, and we could find no similar cases in the surgical literature following any brief surgical procedure. We believe this case to be unique in those regards and aim to raise awareness among ophthalmologists of this postoperative complication, as timely intervention can prevent renal failure and death.Observations: We report the case of a 58-year-old male who developed rhabdomyolysis following vitrectomy for retinal detachment repair under general anesthesia. The patient had several risk factors for this complication including morbid obesity, type II diabetes mellitus, and American Society of Anesthesia class III risk profile. His postoperative course was notable for significant myalgias in the postoperative recovery area, followed several hours later by oliguria, "root beer" colored urine, and a markedly elevated creatinine kinase level. He was hospitalized for two days for intravenous hydration and monitoring of his renal function and has fully recovered.Relevance: As the prevalence of obesity and type II diabetes mellitus increase worldwide, ophthalmologists need to be aware of the signs and symptoms of postoperative rhabdomyolysis.

    The diagnosis conduct disorder (CD) is characterized by aggressive (e.g., physical aggression) as well as nonaggressive symptoms (e.g., violation of rules, truancy). Conclusions regarding the course and prognosis, or recommendations for effective interventions, seem not to be equally valid for the whole patient group. DSM-IV-TR included subtyping age-of-onset as a prognostic criterion, even though the evidence base for subtyping from age of onset was rather sparse. The relevant literature on CD has grown substantially since the publication of DSM-IV-TR in 1994. For the new DSM-5 edition, some important issues were discussed, for example, consideration of personality traits, female-specific or dimensional criteria, and adding a childhood-limited subtype (Moffitt et al., 2008). Nevertheless, the diagnostic protocol for CD was not changed in the most parts in the new edition of the DSM-5; the addition of a CD specifier with limited emotions is the most relevant change. On the basis of the existing evidence base, this review discusses whether the modifications in DSM-5 are helpful for fulfilling the requirements of a reliable and valid psychiatric classification.

Third-year residents performed MSICS using the modified Blumenthal technique. Subconjunctival anesthesia was administered by injecting 2% xylocaine with adrenalin into the superior conjunctiva, and retrobulbar anesthesia by injecting 2 mL of 2% xylocaine with adrenalin into the retrobulbar space. We studied the following variables: intraoperative pain score rated on a 100-point visual analog scale (VAS, operative time, and injection and operative complications.Results: A mean age of 69 vs 70 years, an operative time of 47.1 (SD, 9.9 min vs 47.7 (10.9 min, and a median (interquartile range pain score of 40 (range, 20–70 vs 40 (range, 20–50 were observed in the subconjunctival and the retrobulbar groups, respectively. The injection complication of subconjunctival hemorrhage was significantly higher in the subconjunctival group (25.3% compared to the retrobulbar group (1.3%. The operative complication rate between groups was not different (P > 0.05.Conclusion: Both, superior subconjunctival anesthesia and retrobulbar anesthesia were effective during MSICS when used in a residency training program.Keywords: subconjunctival anesthesia, retrobulbar anesthesia, cataract surgery, small-incision cataract surgery, visual analog scale, pain score

    In studies of sensory contributions to motor control, it may be advantageous to temporarily reduce the sensitivity of specific sensory systems. This article details a method for non-invasively inducing cutaneous anesthesia, leaving proprioceptive and motor functions intact. This method, called alternating-pulse iontophoresis, differs from conventional direct-current (DC) iontophoretic drug delivery in that adjacent drug delivery electrodes are stimulated out-of-phase. The total current delivered at any instant is then less than that produced during a comparable DC application, while the uniformity of drug delivery is expected to improve. Effective delivery of local anesthetics to the cutaneous foot soles by alternating-pulse iontophoresis was demonstrated using cutaneous pressure sensory threshold levels (STL's) assessed with Semmes-Weinstein monofilaments (arbitrary units of perceived force, or a.u.). Thirteen of 16 healthy subjects achieved a level of anesthesia greater than or equal to that normally associated with clinical peripheral sensory neuropathy. Average STL's measured prior to the anesthesia procedure were 4.00 a.u. ( approximately 10 mN). Immediately following the procedure, STL's were elevated to an average of 5.40 a.u. ( approximately 246 mN) and averaged 4.97 a.u. ( approximately 92 mN) after 50 min of standing. A number of research and clinical applications for this technique are suggested.

    Full Text Available Surgical removal of solid tumors is of utmost importance as total resection can be curative. The surgical insult however itself may result in tumor micrometastasis coupled with depression of cell-mediated immunity culminating in tumor recurrence. Recent research suggests that few anesthetic agents or procedures can influence pathophysiology of metastasis in the postoperative period. Whereas opioids and volatile anesthetics have been implicated in angiogenesis and immunosuppression, evidences accumulated over the recent years have undoubtedly highlighted the attenuation of immunosuppression by regional anesthetic agents thereby making it superior over general anesthesia in preventing cancer recurrence. As anesthetic drugs are given at that time when patient is at the maximum risk of spread of metastasis, thus an understanding of the effect of anesthesia drugs and their impact on tumor metastasis is important so that appropriate anesthetic strategy can be made to improve long term survival in these patients. The purpose of the present review is therefore to emphasize the pivotal role of various anesthetic agents and anesthesia techniques in preventing tumor recurrence after surgery.

    The gateways to advancements in medical fields have always been accessed through the coalition between various specialties. It is almost impossible for any specialty to make rapid strides of its own. However, the understanding of deeper perspectives of each specialty or super specialty is essential to take initiatives for the progress of the other specialty. Endocrinology and anesthesiology are two such examples which have made rapid progress in the last three decades. Somehow the interaction and relationship among these medical streams have been only scarcely studied. Diabetes and thyroid pathophysiologies have been the most researched endocrine disorders so far in anesthesia practice but even their management strategies have undergone significant metamorphosis over the last three decades. As such, anesthesia practice has been influenced vastly by these advancements in endocrinology. However, a comprehensive understanding of the relationship between these two partially related specialties is considered to be an essential cornerstone for further progress in anesthesia and surgical sciences. The current review is an attempt to imbibe the current and the changing perspectives so as to make the understanding of the relationship between these two medical streams a little simple and clearer.

    Full Text Available Purpose: The main objective of this survey is to describe the current practice of thoracic anesthesia in the Middle Eastern (ME region. Methods: A prospective online survey. An invitation to participate was e-mailed to all members of the ME thoracic-anaesthesia group. A total of 58 members participated in the survey from 19 institutions in the Middle East. Questions concerned ventilation strategies during one-lung ventilation (OLV, anesthesia regimen, mode of postoperative analgesia, use of lung isolation techniques, and use of i.v. fluids. Results: Volume-controlled ventilation was favored over pressure-controlled ventilation (62% vs 38% of respondents, P<0.05; 43% report the routine use of positive end-expiratory pressure. One hundred percent of respondents report using double-lumen tube (DLT as a first choice airway to establish OLV. Nearly a third of respondents, 31.1%, report never using bronchial blocker (BB in their thoracic anesthesia practice. Failure to pass a DLT and difficult airway are the most commonly cited indications for BB use. Regarding postoperative analgesia, the majority 61.8% favor thoracic epidural analgesia over other techniques (P<0.05. Conclusions: Our survey provides a contemporary snapshot of the ME thoracic anesthetic practice.

    Demonstrably accurate records facilitate clinical decision making, improve patient safety, provide better defense against frivolous lawsuits, and enable better medical policy decisions. Anesthesia Information Management Systems (AIMS) have the potential to improve on the accuracy and reliability of handwritten records. Interfaces with electronic recording systems within the hospital or wider community allow correlation of anesthesia relevant data with biochemistry laboratory results, billing sections, radiological units, pharmacy, earlier patient records, and other systems. Electronic storage of large and accurate datasets has lent itself to quality assurance, enhancement of patient safety, research, cost containment, scheduling, anesthesia training initiatives, and has even stimulated organizational change. The time for record making may be increased by AIMS, but in some cases has been reduced. The question of impact on vigilance is not entirely settled, but substantial negative effects seem to be unlikely. The usefulness of these large databases depends on the accuracy of data and they may be incorrect or incomplete. Consequent biases are threats to the validity of research results. Data mining of biomedical databases makes it easier for individuals with political, social, or economic agendas to generate misleading research findings for the purpose of manipulating public opinion and swaying policymakers. There remains a fear that accessibility of data may have undesirable regulatory or legal consequences. Increasing regulation of treatment options during the perioperative period through regulated policies could reduce autonomy for clinicians. These fears are as yet unsubstantiated.

    Full Text Available Biosignal analysis is one of the most important topics that researchers have tried to develop during the last century to understand numerous human diseases. Electroencephalograms (EEGs are one of the techniques which provides an electrical representation of biosignals that reflect changes in the activity of the human brain. Monitoring the levels of anesthesia is a very important subject, which has been proposed to avoid both patient awareness caused by inadequate dosage of anesthetic drugs and excessive use of anesthesia during surgery. This article reviews the bases of these techniques and their development within the last decades and provides a synopsis of the relevant methodologies and algorithms that are used to analyze EEG signals. In addition, it aims to present some of the physiological background of the EEG signal, developments in EEG signal processing, and the effective methods used to remove various types of noise. This review will hopefully increase efforts to develop methods that use EEG signals for determining and classifying the depth of anesthesia with a high data rate to produce a flexible and reliable detection device.

    Full Text Available Introduction : Hospital infections are one of the important reasons of mortality and incurred expenses. Therefore, we must control these infections by identifying contamination sources. The aim of this study was the determination of bacterial pollution of corrugated anesthesia sets in surgical rooms. Methods: This study was an analytic-description one performed in training hospitals of Yazd city. Research sample was 440 cases provided from different parts of corrugate after completing the anesthesia period by wet sterile swabs and transferred to culture media. On Thursday, each week, a sample from different parts of tube after sterilizing with cetrimide solution was obtained. Finally, after 24 hours, culture medias were studied for colony growth. Results: Obtained results indicated that of 440 cases taken samples, 343 cases were without bacterial pollution, 71 cases (19.29% had bacterial pollution of samples before sterilizing and 26 cases (36.1% were polluted after tube sterilizing. Conclusion: Sampling and culturing from used equipment and tools in hospital is one of the important actions for identifying and controlling hospital infections. Obtained results from this study indicated that of 440 cases, there were 97 cases of pollution. Therefore, it is suggested that anti bacterial filters should be installed before Y form piece of tubes in anesthesia machines and disposable corrugated tubes should replace traditional tubes. In addition, it seems necessary that wider investigations should be done.

    Abstract The use of midazolam as a tranquilizer for anesthesia in mustelids in conjunction with the cyclohexamine ketamine is not well documented. Because midazolam is fast acting, inexpensive, and quickly metabolized, it may serve as a good alternative to other more commonly used tranquilizers. We trapped and anesthetized 27 Pacific martens (Martes caurina) in Lassen National Forest (northern California, US) August 2010-April 2013. We assessed anesthesia with ketamine at 18 and 25 mg/kg combined with 0.2 mg/kg of midazolam by comparing mean times of induction, return to consciousness, and recovery, plus physiologic parameters. No reversal was used for the midazolam portion of the anesthetic. Mean (±SD) induction for both ketamine dosages was 1.7±0.5 and 1.8±1.0 min, respectively. Return to consciousness mean times were 8.0 min longer (Pmidazolam provided reliable field anesthesia for Pacific martens, and supplemental oxygen is recommended as needed.

    Field anesthesia is often necessary for both invasive and noninvasive procedures on wild animals. We describe basic principles of safe anesthetic delivery, monitoring, and recovery for application in procedures involving free-ranging wildlife. For invasive procedures, the potential for immediate and lasting pain must be addressed and appropriate analgesia provided. In situations where the minimum standard of safe anesthesia and effective analgesia cannot be provided, the investigator and approving bodies should rigorously evaluate the risk to the patient against the value of the data obtained. This document is intended to serve as a resource for Institutional Animal Care and Use Committees, biologists, veterinarians, and other researchers planning projects that involve free-ranging wildlife in field conditions.

    Abstract Background: The differences in the incidence and severity of emergence agitation (EA) and emergence times between desflurane and sevoflurane anesthesia have not been as clearly elucidated in children as in adults. Methods: The design of the study is a systematic review with meta-analysis of randomized controlled trials. The study methodology is based on the Cochrane Review Methods. A comprehensive literature search was conducted to identify clinical trials comparing the incidence or severity of EA and emergence times in children anesthetized with desflurane or sevoflurane. Two reviewers independently assessed each study according to predefined inclusion criteria and extracted data from each study using a prespecified data extraction form. The data from each study were combined using a fixed effect or random effect model to calculate the pooled risk ratio (RR) or standardized mean difference (SMD) and 95% confidence interval (CI). Funnel plots were used to assess publication bias. Subgroup and sensitivity analyses were performed. Results: Fourteen studies met the inclusion criteria. Among the 1196 patients in these 14 studies, 588 received desflurane anesthesia and 608 received sevoflurane anesthesia. The incidence of EA was comparable between the 2 groups (pooled RR = 1.21; 95% CI: 0.96–1.53; I2 = 26%), and so was the severity of EA (EA score) between the 2 groups (SMD = 0.12; 95% CI: −0.02 to 0.27; I2 = 0%). Extubation and awakening times were shorter in the desflurane group than in the sevoflurane group; the weighted mean differences were −2.21 (95% CI: −3.62 to −0.81; I2 = 93%) and −2.74 (95% CI: −3.80 to −1.69; I2 = 85%), respectively. No publication bias was found in the funnel plot. The subgroup analysis based on the type of EA scale showed a higher incidence of EA in the desflurane group than in the sevoflurane group in studies using 3-, 4-, or 5-point EA scales; the pooled RR was 1.38 (95% CI: 1.10–1.73; I2 = 37%).

    venous stasis. In another experimental series the effect of general pentobarbital anesthesia on the vasoconstrictor activity in response to venous stasis locally in subcutaneous and muscle tissue in the hind limb was examined in 6 dogs. It was found that during the first 2-3 h of anesthesia...... the vasoconstrictor response was present in both tissues although the response in muscle tissue exhibited a great variation between the dogs during this period. However, after 4-5 h of anesthesia the response was abolished in both tissues. During neurolept anesthesia with fentanyl/N2O the same vasoconstrictor...... response was demonstrated in the hindleg 1 h and 5 h after induction of the anesthesia. It is concluded that pentobarbital anesthesia abolishes the arteriolar constriction induced by venous stasis. The mechanism may be blockade of the local sympathetic vasoconstrictor fibres or interference with myogenic...

    Full Text Available ABSTRACT Steinert's disease is an intrinsic disorder of the muscle with multisystem manifestations. Myotonia may affect any muscle group, is elicited by several factors and drugs used in general anesthesia like hypnotics, sedatives and opioids. Although some authors recommend the use of regional anesthesia or combined anesthesia with low doses of opioids, the safest anesthetic technique still has to be established. We performed a continuous spinal anesthesia in a patient with Steinert's disease undergoing laparoscopic cholecystectomy using 10 mg of bupivacaine 0.5% and provided ventilatory support in the perioperative period. Continuous spinal anesthesia was safely used in Steinert's disease patients but is not described for laparoscopic cholecystectomy. We reported a continuous spinal anesthesia as an appropriate technique for laparoscopic cholecystectomy and particularly valuable in Steinert's disease patients.

    Full Text Available Background: Spinal anesthesia has replaced general anesthesia in obstetric practice. Hemodynamic instability is a common, but preventable complication of spinal anesthesia. Preloading the circulation with intravenous fluids is considered a safe and effective method of preventing hypotension following spinal anesthesia. We had conducted a study to compare the hemodynamic stability after volume preloading with either Ringer′s lactate (RL or tetrastarch hydroxyethyl starch (HES or succinylated gelatin (SG in the patients undergoing cesarean section under spinal anesthesia. Materials and Methods: It was a prospective, double-blinded and randomized controlled study. Ninety six ASA-I healthy, nonlaboring parturients were randomly divided in 3 groups HES, SG, RL (n = 32 each and received 10 ml/kg HES 130/0.4; 10 ml/kg SG (4% modified fluid gelatin and 20 ml/kg RL respectively prior to SA scheduled for cesarean section. Heart rate, blood pressure (BP, oxygen saturation was measured. Results: The fall in systolic blood pressure (SBP (<100 mm Hg noted among 5 (15.63%, 12 (37.5% and 14 (43.75% parturients in groups HES, SG, RL respectively. Vasopressor (phenylephrine was used to treat hypotension when SBP <90 mm Hg. Both the results and APGAR scores were comparable in all the groups. Lower preloading volume and less intra-operative vasopressor requirement was noted in HES group for maintaining BP though it has no clinical significance. Conclusion: RL which is cheap, physiological and widely available crystalloid can preload effectively and maintain hemodynamic stability well in cesarean section and any remnant hypotension can easily be manageable with vasopressor.

    Anesthesia in infancy impairs performance in recognition memory tasks in mammalian animals, but it is unknown if this occurs in humans. Successful recognition can be based on stimulus familiarity or recollection of event details. Several brain structures involved in recollection are affected by anesthesia-induced neurodegeneration in animals. Therefore, we hypothesized that anesthesia in infancy impairs recollection later in life in humans and rats. Twenty eight children ages 6-11 who had undergone a procedure requiring general anesthesia before age 1 were compared with 28 age- and gender-matched children who had not undergone anesthesia. Recollection and familiarity were assessed in an object recognition memory test using receiver operator characteristic analysis. In addition, IQ and Child Behavior Checklist scores were assessed. In parallel, thirty three 7-day-old rats were randomized to receive anesthesia or sham anesthesia. Over 10 months, recollection and familiarity were assessed using an odor recognition test. We found that anesthetized children had significantly lower recollection scores and were impaired at recollecting associative information compared with controls. Familiarity, IQ, and Child Behavior Checklist scores were not different between groups. In rats, anesthetized subjects had significantly lower recollection scores than controls while familiarity was unaffected. Rats that had undergone tissue injury during anesthesia had similar recollection indices as rats that had been anesthetized without tissue injury. These findings suggest that general anesthesia in infancy impairs recollection later in life in humans and rats. In rats, this effect is independent of underlying disease or tissue injury.

    Continuous spectral EEG activity monitoring has been used in adults as a monitor of brain activity during anesthesia. It has not been used in infants. We studied 22 infants less than 7 months old undergoing minor surgery. Halothane alone or minimal Halothane anesthesia associated with caudal epidural anesthesia were used. Life-Scan analysis, in spite of wide individual variations, allowed us to detect infraclinical hypoxia episodes, it provided informations about operative confort, depth of anesthesia and added in the post-operative period an objective criteria to clinical evaluation of pain. A wide use of such a monitoring is warranted in infants.

    With the spread of total intravenous anesthesia, clinical pharmacology has become more important. We report Microsoft Excel file applying three compartment model and response surface model to clinical anesthesia. On the Microsoft Excel sheet, propofol, remifentanil and fentanyl effect-site concentrations are predicted (three compartment model), and probabilities of no response to prodding, shaking, surrogates of painful stimuli and laryngoscopy are calculated using predicted effect-site drug concentration. Time-dependent changes in these calculated values are shown graphically. Recent development in anesthetic drug interaction studies are remarkable, and its application to clinical anesthesia with this Excel file is simple and helpful for clinical anesthesia.

    Background Traditionally, anesthesiologists have relied on nonspecific subjective and objective physical signs to assess patients’ comfort level and depth of anesthesia. Commercial development of electrical monitors, which use low- and high-frequency electroencephalogram (EEG) signals, have been developed to enhance the assessment of patients’ level of consciousness. Multiple studies have shown that monitoring patients’ consciousness levels can help in reducing drug consumption, anesthesia-related adverse events, and recovery time. This clinical study will provide information by simultaneously comparing the performance of the SNAP II (a single-channel EEG device) and the bispectral index (BIS) VISTA (a dual-channel EEG device) by assessing their efficacy in monitoring different anesthetic states in patients undergoing general anesthesia. Objective The primary objective of this study is to establish the range of index values for the SNAP II corresponding to each anesthetic state (preinduction, loss of response, maintenance, first purposeful response, and extubation). The secondary objectives will assess the range of index values for BIS VISTA corresponding to each anesthetic state compared to published BIS VISTA range information, and estimate the area under the curve, sensitivity, and specificity for both devices. Methods This is a multicenter, prospective, double-arm, parallel assignment, single-blind study involving patients undergoing elective surgery that requires general anesthesia. The study will include 40 patients and will be conducted at the following sites: The Ohio State University Medical Center (Columbus, OH); Northwestern University Prentice Women's Hospital (Chicago, IL); and University of Miami Jackson Memorial Hospital (Miami, FL). The study will assess the predictive value of SNAP II versus BIS VISTA indices at various anesthetic states in patients undergoing general anesthesia (preinduction, loss of response, maintenance, first purposeful

One e-learning tool of note is the virtual patient (VP, a type of computer software that simulates real-life clinical scenarios, in which the learner emulates the role of health care provider to obtain the history, conduct examination, and make diagnoses and management decisions. VPs have been in use since 1993. Early designs were based on serial screen-cards of patient history, examination, investigations, diagnoses, treatment, and outcome, which the learner explored. With the development of web technology, VPs can now be accessed via the Internet and are more versatile, supporting different structural designs to suit a variety of learning objectives, and they can branch via different routes through a case. Using VPs has a number of advantages: 1 VPs improve access to learning material, 2 VPs help learners to acquire higher order cognitive skills like strategic thinking and decision making, 3 VPs provide a safe environment to practice, 4 VPs help to teach interdisciplinary care, and 5 VPs can be used instead of patients for examination. A number of well-known VP player systems are in use today: CASUS, CAMPUS, web-based Simulation of Patients, OpenLabyrinth, and vpSim. At the Chinese University of Hong Kong, we have also developed a web-based VP authoring and player system called Formative Assessment Case Studies (FACS, which is run by our Teaching and Learning Resources Centre. FACS has been integrated into Year-5 Anesthesia teaching since 2006.

    2015-09-01

    In this review article, we address issues related to using data from anesthesia information management systems (AIMS) to deliver near real-time alerts via AIMS workstation popups and/or alphanumeric pagers and post hoc reports via e-mail. We focus on reports and alerts for influencing the behavior of anesthesia providers (i.e., anesthesiologists, anesthesia residents, and nurse anesthetists). Multiple studies have shown that anesthesia clinical decision support (CDS) improves adherence to protocols and increases financial performance through facilitation of billing, regulatory, and compliance documentation; however, improved clinical outcomes have not been demonstrated. We inform developers and users of feedback systems about the multitude of concerns to consider during development and implementation of CDS to increase its effectiveness and to mitigate its potentially disruptive aspects. We discuss the timing and modalities used to deliver messages, implications of outlier-only versus individualized feedback, the need to consider possible unintended consequences of such feedback, regulations, sustainability, and portability among systems. We discuss statistical issues related to the appropriate evaluation of CDS efficacy. We provide a systematic review of the published literature (indexed in PubMed) of anesthesia CDS and offer 2 case studies of CDS interventions using AIMS data from our own institution illustrating the salient points. Because of the considerable expense and complexity of maintaining near real-time CDS systems, as compared with providing individual reports via e-mail after the fact, we suggest that if the same goal can be accomplished via delayed reporting versus immediate feedback, the former approach is preferable. Nevertheless, some processes require near real-time alerts to produce the desired improvement. Post hoc e-mail reporting from enterprise-wide electronic health record systems is straightforward and can be accomplished using system

    Full Text Available Medication errors are common throughout healthcare system and result in significant morbidity and mortality. Medication related incidents are a common form of reported medical errors. In theory they should never occur. These mistakes are also called “Never events”. Some of these are avoidable and preventable events. 50% of these mistakes are preventable. “India records 5.2 million medical injuries a year”. 1 The UN body quantified the number of surgeries taking place every year globally - 234 million. It said surgeries had become common, with one in every 25 people undergoing it at any given time. China conducted the highest number of surgeries followed by Russia and India. In developing countries, the death rate was nearly 10% for a major surgery. 1 All surgeries need one or other form of anaesthesia. Anaesthetic practice is unique because anaesthetists are personally responsible for al l the steps from drug preparation to drug administration. Therefore, they need to have heightened awareness of the risk factors which create conditions for drug errors to occur. 2 Anaesthesia is unusual in requiring the administration of several potent, dan gerous, rapidly acting drugs in a relatively brief timeframe. These drugs would be harmful if given without considerable care and attention to dose, timing and order of administration. These drugs are almost exclusively administered by Anaesthetists and th e drugs are rarely checked by anyone other than the anaesthetist before administration. Drug error in relation to anaesthesia may therefore be of particular interest both to the specialty and the wider population. 3

    The research objective was to study the characteristics of combined anesthesia with epidural componente (CAEC) depending on vegetative nervous system type (VNS) in patients who underwent large scale traumatic surgical operations on abdominal cavity organs. The scientific research was conducted in Anaesthesiology--Reanimation Department of the Scientific Surgical Centre named after acad. MA. Topchubashev, the Ministry of Health of the Azerbaijan Republic. The research objects were 69 patients who underwent operations in conditions of CAEC due to different serious surgical pathologies of abdominal cavity organs. VNS type was identified based on electroencephalogram, Cerdo Vegetative Index (CVI), Hildebrandt coefficient (HC) and single neurophysiological tests. The patients were divided into three groups depending on VNS type: I--normotonics--17 patients (24.7%), II--sympathatonics--25 patients (36.2%), and III--vagotonics--27 patients (39.1%). Blood adrenocorticotropic hormone (ACTH) and cortisol concentration were studied in 3 stages: I -preoperative, II--operation traumatic stage, III--the 1st postoperative days. The other indicators (heart rate, systolic blood pressure--SBP, dyastolic blood pressure--DBR average blood pressure--BP ave., pulse oximetry SpO₂, ECG, gases in blood and acid-base balance, electrolytes, blood glucose level, myocardium oxygen demand--MOD) were registered after 20 minutes and the 2nd day after operation besides the above stages. The research results indicated that it is possible to define the vegetative nervous system type superiority based on complex of single tests data, EEG, ECG, Cerdo Vegetative Index, Hildebrandt coefficient. CAEC can be considered optimun alternative of general anesthesia ensuring neurohumoral and hemodynamic stability in large scale, traumatic operations on abdominal cavity organs. Clinical course of CAEC is characterized by firmer hemodynamic and humoral stability in patients with functional balance of

    Full Text Available Introduction: Anesthesiology is a medical specialty with rapid development in the recent decades. The work of anesthetists, however, is not recognized in the medical circles and research reports that patients have incomplete knowledge about anesthesia and the anesthesiologist. Purpose: The purpose of the present research was to assess the views of patients and doctors of other specialties in Greece, for the role of the anesthesiologist and anesthesia. Material and Methods: The study was conducted at the General Hospital of Thessaloniki, Papageorgiou, with the use of questionnaires, during January-March 2014, and data were analyzed with SPSS 15. The study included 100 participants from the surgical clinics and 50 doctors from other specialties. Results: The vast majority of patients (> 90%, who took part in the research, are aware that the anesthesiologist is a physician but are not aware of the specific tasks undertaken in the peri-operative period. Also, they have knowledge for several of their out of surgery activities, except from their involvement in the radiology department (16%, the pain clinic (23% and the psychiatric clinic (20%. The same lack of knowledge is evident for the latter by the other physicians too (only 22% was aware as well as for the necessary preoperative withhold of food and drink (34%, and the involvement of anesthesiologist in cardiology (44%, psychiatric (22% clinics and radiology department (42%. However, they are generally aware of most of anesthesiologist’s tasks and anesthesia’s complications. Conclusions: The research shows the need to intensify efforts from anesthesiologists to inform patients about issues related to anesthesiology. Doctors of other specialties lack expertise in specific issues of anesthesiology; therefore they need additional training in order to contribute in informing patients.

    Deep anesthesia is commonly used as a model of slow-wave sleep (SWS). Ketamine-xylazine anesthesia reproduces the main features of sleep slow oscillation: slow, large amplitude waves in field potential, which are generated by the alternation of hyperpolarized and depolarized states of cortical neurons. However, direct quantitative comparison of field potential and membrane potential fluctuations during natural sleep and anesthesia is lacking, so it remains unclear how well the properties of sleep slow oscillation are reproduced by the ketamine-xylazine anesthesia model. Here, we used field potential and intracellular recordings in different cortical areas in the cat, to directly compare properties of slow oscillation during natural sleep and ketamine-xylazine anesthesia. During SWS cortical activity showed higher power in the slow/delta (0.1-4 Hz) and spindle (8-14 Hz) frequency range, while under anesthesia the power in the gamma band (30-100 Hz) was higher. During anesthesia, slow waves were more rhythmic and more synchronous across the cortex. Intracellular recordings revealed that silent states were longer and the amplitude of membrane potential around transition between active and silent states was bigger under anesthesia. Slow waves were largely uniform across cortical areas under anesthesia, but in SWS they were most pronounced in associative and visual areas, but smaller and less regular in somatosensory and motor cortices. We conclude that although the main features of the slow oscillation in sleep and anesthesia appear similar, multiple cellular and network features are differently expressed during natural SWS as compared to ketamine-xylazine anesthesia.

Aim of this research was to determine infl uence of propofol, sevoflurane and isoflurane anesthesia on post anesthesia recovery rate.Methods: This was a prospective study; it included 90 patients hospitalized in period form October 2011 to may 2012 year, all patients included in the study underwent lumbar microdiscectomy surgery. Patients were randomly allocated to one of three groups: group 1: propofol maintained anesthesia, group 2: sevoflurane and group 3: isofl urane maintained anesthesia. Assessments of recovery rate were done 1, 5 and 10 minutes post extubation using White fast tracking scoring system.Results: Significant difference was observed only 1 minute after extubation (p=0,025 finding recovery rate to be superior in propofol group. Propofol group compared to inhaled anesthesia with sevoflurane group, shows significantly faster recovery from anesthesia only one minute after extubation (p=0,046. In comparison of propofol group and isofl urane anesthesia group, statistical significance was noticed one minute following extubation (p=0,008. Comparison of propofol group and inhaled anesthesia groups recovery rates were not significantly different at all times measured. When we were comparing sevoflurane and isoflurane anesthesia, recovery rates shoved no signifi cant statistical difference.Conclusions: Recovery rate evaluated by using White fast tracking scoring system was superior and with fewer complications in propofol maintained in comparison to sevoflurane and isoflurane maintained anesthesia only one minute post extubation, while after fifth and tenth minute difference was lost.

    Background and Objectives The presence of sleep apnea (SA) among surgical patients has been associated with significantly increased risk of perioperative complications. Although regional anesthesia has been suggested as a means to reduce complication rates among SA patients undergoing surgery, no data are available to support this association. We studied the association of the type of anesthesia and perioperative outcomes in patients with SA undergoing joint arthroplasty. Methods Drawing on a large administrative database (Premier Inc), we analyzed data from approximately 400 hospitals in the United States. Patients with a diagnosis of SA who underwent primary hip or knee arthroplasty between 2006 and 2010 were identified. Perioperative outcomes were compared between patients receiving general, neuraxial, or combined neuraxial-general anesthesia. Results We identified 40,316 entries for unique patients with a diagnosis for SA undergoing primary hip or knee arthroplasty. Of those, 30,024 (74%) had anesthesia-type information available. Approximately 11% of cases were performed under neuraxial, 15% under combined neuraxial and general, and 74% under general anesthesia. Patients undergoing their procedure under neuraxial anesthesia had significantly lower rates of major complications than did patients who received combined neuraxial and general or general anesthesia (16.0%, 17.2%, and 18.1%, respectively; P = 0.0177). Adjusted risk of major complications for those undergoing surgery under neuraxial or combined neuraxial-general anesthesia compared with general anesthesia was also lower (odds ratio, 0.83 [95% confidence interval, 0.74–0.93; P = 0.001] vs odds ratio, 0.90 [95% confidence interval, 0.82–0.99; P = 0.03]). Conclusions Barring contraindications, neuraxial anesthesia may convey benefits in the perioperative outcome of SA patients undergoing joint arthroplasty. Further research is needed to enhance an understanding of the mechanisms by which neuraxial

    An increase in natural killer (NK) cell activity can be conditioned with a one trial learning paradigm to demonstrate the interaction between the central nervous system (CNS) and the immune system. In order to demonstrate learning possibilities during 'non-conscious' state, mice were anesthetized with a ketamin/rompun mixture and underwent one trial learning with odor cue as the conditioned stimulus (CS) preceding the unconditioned stimulus (US). The results indicated that mice that were exposed to camphor odor cue under the influence of anesthesia can associate the signal with the poly I:C unconditioned stimulus and were able to recall the conditioned response upon reexposure to the CS. Secondly, the conditioned association made in a conscious state can be recalled by exposure to the same olfactory odor cue in a 'non-conscious' state. The increase in the conditioned change in NK cell activity of both situations was significantly higher than the control group. The results demonstrate that learning can take place and the learned response can be recalled under the reduced awareness caused by anesthesia. The findings we report are unusual and novel in that they demonstrate that the CNS can learn new associations under conditions where the host is apparently unaware of the signals being linked. Anesthesia combined with the long interstimulus interval indicates that certain neuronal pathways in the CNS are receptive to second signals (elicited by the US) even when the second signal is separated by one day. This means the conditioned learning of a physiological response can take place unconsciously at a separate level and under situations where the host is totally unaware of the events which the brain is processing and linking as incoming information.

    Regional anesthesia and analgesia benefit the client, the patient, and the practitioner, and their use is becoming the standard for care. Familiarity with the processes involved in the generation of pain aids in understanding the benefits of preemptive and multimodal analgesia. Local anesthetic blocks should be a key component of a treatment plan, along with opioids, nonsteroidal anti-inflammatory drugs, N-methyl-D-aspartate receptor antagonists, and other therapies. Nerve blocks commonly used for dentistry and oral surgery include the infraorbital, maxillary, mental,and mandibular blocks.

    The evidence on the attitude of 60 cancer out-patients to fibrocolonoscopy carried out under general anesthesia was evaluated versus different procedures of intravenous injection. Most patients were scared prior to examination; 83.3% felt sleepy during the procedure while 85% of those anesthetized wouldn't mind receiving narcosis for repeat examination. Propofol (diprivan) alone showed an advantage over midazolam (dormicum) in being more tolerable and cutting stay at hospital by a third. Ketamin proved undesirable due to psychomimetic effects and delayed regaining of consciousness.

    Anesthesia provision for fetal intervention differs from most other anesthetic situations insofar as anesthesiologists must care for 2 or more patients-each with potentially conflicting requirements. The first is the mother who can readily indicate discomforts, can be monitored directly, and to whom drugs may be administered directly and easily. For the fetus (or fetuses), nociception must be assumed or inferred indirectly, monitoring is limited at best, and drug administration is complicated and often indirect. Fetal and maternal hemodynamic stability must be assured; and a plan to resuscitate the fetus, should problems occur during the procedure, must be developed.

The Quality and Safety Committee of the Society for Pediatric Anesthesia (SPA) has developed a set of critical-event checklists and cognitive aids designed for 3 purposes: (1) as a repository of the latest evidence-based and expert opinion-based information to guide response and management of critical events, (2) as a source of just-in-time information during critical events, and (3) as a method to facilitate a shared understanding of required actions among team members during a critical event. Committee members, who represented children's hospitals from across the nation, used the recent literature and established guidelines (where available) and incorporated the expertise of colleagues at their institutions to develop these checklists, which included relevant factors to consider and steps to take in response to critical events. Human factors principles were incorporated to enhance checklist usability, facilitate error-free accomplishment, and ensure a common approach to checklist layout, formatting, structure, and design.The checklists were made available in multiple formats: a PDF version for easy printing, a mobile application, and at some institutions, a Web-based application using the anesthesia information management system. After the checklists were created, training commenced, and plans for validation were begun. User training is essential for successful implementation and should ideally include explanation of the organization of the checklists; familiarization of users with the layout, structure, and formatting of the checklists; coaching in how to use the checklists in a team environment; reviewing of the items; and simulation of checklist use. Because of the rare and unpredictable nature of critical events, clinical trials that use crisis checklists are difficult to conduct

  7. Anesthetic strategy during endovascular therapy: General anesthesia or conscious sedation? (GOLIATH - General or Local Anesthesia in Intra Arterial Therapy) A single-center randomized trial

    RATIONALE: Endovascular therapy after acute ischemic stroke due to large vessel occlusion is now standard of care. There is equipoise as to what kind of anesthesia patients should receive during the procedure. Observational studies suggest that general anesthesia is associated with worse outcomes...... compared to conscious sedation. However, the findings may have been biased. Randomized clinical trials are needed to determine whether the choice of anesthesia may influence outcome. AIM AND HYPOTHESIS: The objective of GOLIATH (General or Local Anestesia in Intra Arterial Therapy) is to examine whether....... Patients with acute ischemic stroke, scheduled for endovascular therapy, are randomized to receive either general anesthesia or conscious sedation. STUDY OUTCOMES: The primary outcome measure is infarct growth after 48-72 h (determined by serial diffusion-weighted magnetic resonance imaging). Secondary...

    Directory of Open Access Journals (Sweden)

    Nancheva Jasminka

    2016-07-01

    Full Text Available The exposure of neonates, infants and small children to general anesthesia is becoming a common occurrence. Accumulating preclinical data indicate that exposure to commonly used general anesthetic agents during key periods of brain development in this population(between late gestation and 3 to 4 years of age, can lead to apoptotic neurodegeneration, synapse loss, and cognitive and neurobehavioral deficits that persist as the organism matures. New work suggests that infants and small children undergoing some types of surgery could have better recovery if they receive regional anesthesia rather than general anesthesia. In response to this concerns, the Food and drug administration (FDA and the International Research Society in anesthesia (IARS started an initiative called Smart Tots (Strategies for Mitigating Anesthesia- related neuro Toxicity in Tots which examine the effects of anesthesia on brain development. Also another two major prospective studies are ongoing in children : PANDA (Pediatric Anesthesia Neurodevelopment assessment Study project is a large, multi-center study based at the Morgan Stanley Children’s Hospital of New York at Columbia University, and another one is GAS study which is a multisite randomized controlled trial comparing neurodevelopment outcomes in infant receiving general anesthesia compared to spinal and other regional anesthetics to the stress response to surgery. The findings from these studies will help researches to design the safest anesthetic regimens and to develop the new and safer anesthetic drugs for use in pediatric medicine.

  7. Determine the Influence of Time Held in “Knockdown” Anesthesia on Survival and Stress of Surgically Implanted Juvenile Salmonids

    Energy Technology Data Exchange (ETDEWEB)

    Woodley, Christa M.; Wagner, Katie A.; Knox, Kasey M.

    2012-01-31

    The Juvenile Salmon Acoustic Telemetry System (JSATS) was developed for the U.S. Army Corp of Engineers Portland District (USACE) to address questions related to survival and performance measures of juvenile salmonids as they pass through the Federal Columbia River Power System (FCRPS). Researchers using JSATS acoustic transmitters (ATs) were tasked with standardizing the surgical implantation procedure to ensure that the stressors of handling and surgery on salmonids were consistent and less likely to cause effects of tagging in survival studies. Researchers questioned whether the exposure time in 'knockdown' anesthesia (or induction) to prepare fish for surgery could influence the survival of study fish (CBSPSC 2011). Currently, fish are held in knockdown anesthesia after they reach Stage 4 anesthesia until the completion of the surgical implantation of a transmitter, varies from 5 to 15 minutes for studies conducted in the Columbia Basin. The Columbia Basin Surgical Protocol Steering Committee (CBSPSC ) expressed concern that its currently recommended 10-minute maximum time limit during which fish are held in anesthetic - tricaine methanesulfonate (MS-222, 80 mg L-1 water) - could increase behavioral and physiological costs, and/or decrease survival of outmigrating juvenile salmonids. In addition, the variability in the time fish are held at Stage 4 could affect the data intended for direct comparison of fish within or among survival studies. Under the current recommended protocol, if fish exceed the 10-minute time limit, they are to be released without surgical implantation, thereby increasing the number of fish handled and endangered species 'take' at the bypass systems for FCRPS survival studies.

    2003-01-01

    Objective: To observe the influence of local infiltration anesthesia at the scalp-point on acupuncture stimulation induced changes of cerebral blood perfusion in the brain. Methods: Experiments were conducted in 10 healthy volunteer subjects (8 males and 2 females) who were ordered to take a lying position on a specific bed with their heads keeping in a fixed position. Scalp-point used was Motor Area (MS 6). The first syringe needle (gauge-5) was inserted into the scalp from the upper 1/5 of MS-6 and the second syringe needle inserted into the scalp from the middle 2/5 of MS-6 and advanced downward, with the two needles connected to a HAN's Therapeutic Apparatus. Images of the brain were then taken before and after electroacupuncture (EA) stimulation, and after local injection of 1% lidocaine [mixed with epinephrine (1∶200,000, 3 mL)] plus EA by using Siemens ECAM/ICON Single Photo Emission Computed Tomography (SPECT). Intravenous injection of Ethyl cysteinate dimmer 555 MBq was performed before displaying cerebral images. Data of blood functional changing rat (BFCR%) were analyzed quantitatively using a mathematic model. Results: Before EA stimulation, the blood perfusion and function of cerebral cortex, thalamus, basal ganglion and cerebellum on both sides of the brain were basically symmetry. Following EA of MS-6, BFCR% of the contralateral thalamus, parietal lobe and the frontal lobe increased significantly. Following local infiltration anesthesia, BFCR% of the contralatral thalamus declined markedly (P<0.05). The results of quantitative analysis were in agreement with those of visual observation. Conclusion: Local infiltration anesthesia of the scalp-point can significantly weaken or block EA stimulation induced changes of BFCR%.

    Although the coadministration of lidocaine with propranolol interferes with the metabolic profile (pharmacokinetics), its pharmacodynamics is still unclear. In this report, we investigate whether propranolol can potentiate the effect of lidocaine. Rats received spinal anesthesia with lidocaine co-injected with propranolol. After intrathecal injections of drugs in rats, three neurobehavioral examinations (motor function, proprioception, and nociception) were performed. We showed that lidocaine and propranolol elicited a spinal blockade in motor function, proprioception, and nociception. Propranolol at the dose of 0.82 μmol/kg produced no spinal anesthesia. Co-administration of lidocaine [50% effective dose (ED(50)) or ED(95)] and propranolol (0.82 μmol/kg) produced greater spinal anesthesia than lidocaine (ED(50) or ED(95)), respectively. These preclinical findings demonstrated that propranolol and lidocaine displayed spinal anesthesia. When combined with propranolol, lidocaine elicited a supra-additive effect of spinal anesthesia.

    In the past, general and spinal anesthesia were used for hernia surgery, but nowadays local anesthesia has become the method of choice for hernia repair, especially in outpatient patients. The one-day surgery is sufficient in the management of this pathology. The advantages of local anesthesia are simplicity, safety, extended postoperative analgesia, early mobilization, lack post-anesthesia effects, and low costs. From January 2004 to December 2008 we observed 297 male patients with inguinal hernia. These patients were divided, with rigorous chronological order of hospital admission, in two study groups, different for anesthetic techniques used. Our controlled randomized clinical trial examines the effectiveness of local anesthesia to reduce the time of hospitalization, without alteration of results, and particularly the degree of satisfaction of patients surgical treated for inguinal hernia.

  16. Anesthesia in pregnant women with HELLP syndrome: case report

    Directory of Open Access Journals (Sweden)

    Eduardo Barbin Zuccolotto

    Full Text Available Abstract Background and objectives: HELLP syndrome, characterized by hemolysis, high levels of liver enzyme, and low platelet count, is an advanced clinical stage of pre-eclampsia, progressing to high maternal (24% and perinatal (up 40% mortality, despite childbirth care in a timely manner. The goal is to describe the anesthetic management of a case with indication to emergency cesarean. Case report: Female patient, 36 years old, gestational age of 24 weeks, with hypertensive crisis (BP 180/100 mmHg and severe headache, was admitted to the operating room for a cesarean section after diagnosis of HELLP syndrome. Indicated for general anesthesia, we opted for total intravenous with intubation after rapid sequence induction with propofol and remifentanil in continuous target-controlled infusion, and rocuronium at a dose of 1.2 mg/kg. Maintenance was achieved with propofol and remifentanil. The surgical procedure was uneventful, the child was born with APGAR 1/5 and transferred to the NICU. At the end of surgery, the patient was extubated in the operating room and taken to the ICU. The postoperative period was uneventful with no changes worthy of note and the patient was discharged on the sixth postoperative day. Conclusion: When general anesthesia is the choice in parturient with HELLP syndrome, tracheal intubation with rapid sequence induction due to possible difficult airway, as well as the use of drugs to control the hemodynamic response can minimize the complications associated with the procedure, as occurred in this case.

  17. A review of tricaine methanesulfonate for anesthesia of fish

    Energy Technology Data Exchange (ETDEWEB)

    Carter, Kathleen M.; Woodley, Christa M.; Brown, Richard S.

    2011-01-01

    Tricaine methanesulfonate (TMS) is the only FDA approved anesthetic for use in a select number of fish species, including salmonids. It is used widely in hatcheries and research to immobilize fish for marking or transport and to suppress sensory systems during invasive procedures. Improper use can decrease fish viability and possibly distort physiological data. Since animals may be anesthetized by junior staff or students who may have little experience in fish anesthesia, training in the proper use of TMS may decrease variability in results and increase fish survival. This document acts as a primer on the use of TMS for anesthetizing juvenile salmonids, with an emphasis on its use in surgical applications. Within, we briefly discuss many aspects TMS. We describe the legal uses for TMS, and what is currently known about the proper storage and preparation of the anesthetic. We outline methods and precautions for administration and changes in fish behavior during progressively deeper anesthesia. We also discuss the physiological effects of TMS and its potential for decreasing fish health.

  18. Congenital Corneal Anesthesia and Neurotrophic Keratitis: Diagnosis and Management

    Directory of Open Access Journals (Sweden)

    Flavio Mantelli

    2015-01-01

    Full Text Available Neurotrophic keratitis (NK is a rare degenerative disease of the cornea caused by an impairment of corneal sensory innervation, characterized by decreased or absent corneal sensitivity resulting in epithelial keratopathy, ulceration, and perforation. The aetiopathogenesis of corneal sensory innervation impairment in children recognizes the same range of causes as adults, although they are much less frequent in the pediatric population. Some extremely rare congenital diseases could be considered in the aetiopathogenesis of NK in children. Congenital corneal anesthesia is an extremely rare condition that carries considerable diagnostic and therapeutic problems. Typically the onset is up to 3 years of age and the cornea may be affected in isolation or the sensory deficit may exist as a component of a congenital syndrome, or it may be associated with systemic somatic anomalies. Accurate diagnosis and recognition of risk factors is important for lessening long-term sequelae of this condition. Treatment should include frequent topical lubrication and bandage corneal or scleral contact lenses. Surgery may be needed in refractory cases. The purpose of this review is to summarize and update data available on congenital causes and treatment of corneal hypo/anesthesia and, in turn, on congenital NK.

    2013-04-01

    Full Text Available Niemann-Pick disease (NPD is an autosomal recessive, lipid storage disorder caused by the deficiency of the lysosomal enzyme sphingomyelinase or defective cholesterol transport from lysosome to cytosol. The clinical symptoms and signs include dysphagia, loss of motor function, hepatosplenomegaly, recurred respiratory infections, seizure, mental retardation, spasticity, myoclonic jerks and ataxia, but vary depending on the type of this disease. According to the observed pathology, patients require specialized therapy. Due to the high prevalence of the pathology in this group of patients, surgical interventions requiring general anaesthesia are common. Anesthetists have some difficulties with this group of patients. One of them is difficult ventilation because of hepatosplenomegaly and the other is difficult intubation. The metabolism of some of the anesthetic agents may be affected due to chronic use of anticonvulsant agents. Liver enzymes are elevated and platelet counts are reduced. Here we report an anesthesia management, difficulties and post-op follow up in a female child having NPD. Anesthetists have some difficulties in ventilation and intubation with NPD patients. In this situation ventilation should be with low tidal volume and high frequency. Because anesthetic agents might cause liver damage, they should be used cautiously. As a result, with keeping mind all these pathologies, anesthesia management to these patients should be used cautiously. (Journal of Current Pediatrics 2013; 11: 42-4

The attending anesthesiologist has to face numerous daunting tasks while administering anesthesia to such patients. The challenging scenarios can be encountered at any stage, be it preoperative, intra-op or postoperative period. Preoperatively, deranged thyroid physiology warrants optimal preparation, while anticipated difficult airway due to enlarged thyroid gland further adds to the anesthetic challenges. Cardiac complications are equally challenging as also the presence of various co-morbidities which make the task of anesthesiologist extremely difficult. Thyroid storm can occur during intra-op and post-op period in inadequately prepared surgical patients. Postoperatively, numerous complications can develop that include hemorrhage, laryngeal edema, nerve palsies, tracheomalacia, hypocalcemic tetany, pneumothorax, etc., The present review aims at an in-depth analysis of potential risk factors and challenges during administration of anesthesia and possible complications in patients with thyroid disease.

    Full Text Available The leading patient complaint during the perioperative period for penile prosthesis implantation is postoperative pain, while emesis and urticaria also affect the procedure’s perceived success. In analyzing surgical outcomes, assessment of the anesthetic for postoperative pain and side effects should be included. This paper retrospectively reviews 90 consecutive, primary inflatable penile prosthetic operations performed by a single surgeon at one private medical center. Fifty-seven patients were included in final analysis. Patients who had more than one procedure that day or who used chronic pain medication were excluded. The type and amount of each drug used for each respective side effect (within the first 24 hours after procedure were compared to determine relative benefit. Twenty patients received general anesthesia (denoted herein as “GA” and 37 received spinal (or also known as subarachnoid anesthesia (denoted herein as “SA”. Patients receiving GA had significantly greater (P<0.0001 occurrence and amount of intravenous pain treatment than those receiving SA. Patients with SA required less intravenous pain medication and less treatment for nausea/emesis.

    Method: Fifty ASA physical status I-II patients of either sex, aged between 18 and 60 years were randomly divided into two groups to receive either propofol infusion (group P, n=25 or sevoflurane (group S, n=25. Cardiovascular parameters, SpO2 and bispectral index (BIS scores were recorded. Time to eye opening, hand squeezing and achieve modified Aldrete's Score and #8805; 9 and the incidence of complications were noted. Results: Early recovery times [eye opening, hand squeezing and achieve modified Aldrete's Score and #8805; 9] were significantly longer in group P (P 0.05. The incidence of post-operative nausea and vomiting was significantly higher in group S. Conclusions: The present study which adjusted propofol infusion rate and sevoflurane concentration according to BIS scores revealed that maintenance of anesthesia with sevoflurane is associated with faster recovery than anesthesia with propofol. Propofol resulted in a significantly lower incidence of postoperative nausea and vomiting. [Natl J Med Res 2015; 5(1.000: 52-56

    Anesthesia information management systems must often be tailored to fit the environment in which they are implemented. Extensive customization necessitates that systems be analyzed for both accuracy and completeness of documentation design to ensure that the final record is a true representation of practice. The purpose of this study was to determine the accuracy of a recently installed system in the capture of key perianesthesia data. This study used an observational design and was conducted using a convenience sample of nurse anesthetists. Observational data of the nurse anesthetists'delivery of anesthesia care were collected using a touch-screen tablet computer utilizing an Access database customized observational data collection tool. A questionnaire was also administered to these nurse anesthetists to assess perceived accuracy, completeness, and satisfaction with the electronic documentation system. The major sources of data not documented in the system were anesthesiologist presence (20%) and placement of intravenous lines (20%). The major sources of inaccuracies in documentation were gas flow rates (45%), medication administration times (30%), and documentation of neuromuscular function testing (20%)-all of the sources of inaccuracies were related to the use of charting templates that were not altered to reflect the actual interventions performed.

    Full Text Available Background: This randomized study was conducted to compare the hemodynamic changes and emergence characteristics of sevoflurane versus propofol anesthesia for microlaryngeal surgery. Methods: Forty adult patients undergoing microlaryngoscopy were randomly allocated into two groups. In propofol group, anesthesia was induced with 2-3 mg/kg propofol and maintained with propofol infusion 50-200 μg/kg/h. In sevoflurane group induction was carried out with 5-8% sevoflurane and maintained with sevoflurane in nitrous oxide and oxygen. The propofol and sevoflurane concentrations were adjusted to maintain the bispectral index of 40-60. All patients received fentanyl 2 μg/kg before induction and succinylcholine 2 mg/kg to facilitate tracheal intubation. The hemodynamic changes during induction and suspension laryngoscopy were compared. In addition, the emergence time, time to extubation, and recovery were assessed. Results: The changes in heart rate were comparable. The mean arterial pressure was significantly lower after induction and higher at insertion of operating laryngoscope in propofol group as compared to sevoflurane group. More patients in propofol group had episodes of hypotension and hypertension than sevoflurane group. The emergence time, extubation times, and recovery time were similar in both groups. Conclusion: We found that sevoflurane showed advantage over propofol in respect of intraoperative cardiovascular stability without increasing recovery time.

    Exposure to urethane anesthesia reportedly produces selective neuronal cell loss in the piriform cortex of young brains; however, resulting functional deficits have not been investigated. The present study found abnormalities in piriform cortex activity of isolated brains in vitro that were harvested from guinea pigs exposed to urethane anesthesia at 14 days of age. Current source density (CSD) analysis and voltage-sensitive dye (VSD) imaging experiments were conducted 48h after urethane injection. We applied paired-pulse stimulation to the lateral olfactory tract (LOT) and assessed short-interval intra-cortical inhibition in the piriform cortex. CSD analysis revealed that a current sink in layer Ib remained active in response to successive stimuli, with an inter-stimulus interval of 30-60 ms, which was typically strongly inhibited. VSD imaging demonstrated stronger and extended neural activity in the urethane-treated piriform cortex, even in response to a second stimulus delivered in short succession. We identified gamma-aminobutyric acid (GABA) ergic neurons in the piriform cortex of sham and urethane-treated animals and found a decrease in GABA-immunoreactive cell density in the urethane group. These results suggest that urethane exposure induces loss of GABAergic interneurons and a subsequent reduction in paired-pulse inhibition in the immature piriform cortex.

    The advent of newer developments in anesthesia techniques and current clinical scenario has necessitated assurance of quality anesthesia services delivery. Numerous factors including availability of newer drugs, availability of newer advanced monitoring gadgets, increased awareness among the patient population, implementation of newer medico-legal laws and professional competitiveness has mandated a quality control and assurance in anesthesia. These domains of quality control are adapted from public health and are being incorporated into daily anesthesia practice in a gradual and phased manner. Quality control and assurance can be assessed and measured with certain quality indicators, which are also helpful in determining the perioperative outcome in anesthesia and surgical practice. Patient's perception about various anesthetic procedures, drug effects and recovery state are the prime underlying basis for assessing the quality assurance and control. At the same time, a positive impact of feedback mechanism cannot be under-emphasized while aiming for improvement in delivery of quality anesthesia services. The current review is aimed at highlighting the important aspects associated with quality assurance and quality control in anesthesia practice.

In this review we outline clinical manifestations and current medical treatment of the disease, and general principles of anesthetizing these patients. We focus on the role of regional anesthesia, including neuroaxial anesthesia, which may serve as a safe alternative to general anesthesia but can be technically challenging. We address concerns regarding abnormal responses to local anesthesia which have previously been reported in patients with SSc, and explore future developments in technology and pharmacology, which may enable regional anesthesia to be performed more successfully and with fewer complications.Keywords: systemic sclerosis, scleroderma, regional anesthesia, neuroaxial anesthesia

    Full Text Available Abstract Background Radiotherapy (RT has become an important treatment modality in pediatric oncology, but its delivery to young children with cancer is challenging and general anesthesia is often needed. Methods To evaluate whether a psychoeducational intervention might reduce the need for anesthesia, 223 consecutive pediatric cancer patients receiving 4141 RT fractions during 244 RT courses between February 1989 and January 2006 were studied. Whereas in 154 RT courses corresponding with 2580 RT fractions patients received no psychoeducational intervention (group A, 90 RT courses respectively 1561 RT fractions were accomplished by using psychoeducational intervention (group B. This tailored psychoeducational intervention in group B included a play program and interactive support by a trained nurse according to age to get familiar with staff, equipment and procedure of radiotherapy. Results Group A did not differ significantly from group B in age at RT, gender, diagnosis, localization of RT and positioning during RT. Whereas 33 (21.4% patients in group A got anesthesia, only 8 (8.9% patients in group B needed anesthesia. The median age of cooperating patients without anesthesia decreased from 3.2 to 2.7 years. In both uni- and multivariate analyses the psychoeducational intervention significantly and independently reduced the need for anesthesia. Conclusion We conclude that a specifically tailored psychoeducational intervention is able to reduce the need for anesthesia in children undergoing RT for cancer. This results in lower costs and increased cooperation during RT.

    Appropriate and effective anesthesia is critical, because it has a strong influence on laboratory animals, and its affect greatly impacts the experimental data. Inhalational anesthesia by endotracheal intubation is currently prevailing in general anesthesia and is prefered over injection anesthesia, especially for large laboratory animals, because it is a safe and easy control agent. However, it is not common for small laboratory animals, because of the high degree of technical skills required. We assessed the capability of use for mice of the endotracheal intubation by using the endoscope system "TESALA AE-C1" and inhalational anesthesia using a ventilator. Endotracheal intubation was successfully performed on all 10 C57BL/6 mice injected with M/M/B: 0.3/4/5 comprised of medetomidine, midazoram and butorphanol, at a dose of 0.3 mg/kg + 4.0 mg/kg + 5.0 mg/kg body weight/mouse, respectively. After the intubated mice were connected with the inhalational anesthesia circuit and the ventilator, vital signs were measured until 15 min after the connection. The data with M/M/B: 0.3/4/5 showed stable and normal values, which indicated that this new endotracheal intubation method was simple, reliable and safe, which mean that this anesthesia is favorable in regard to the animal's welfare.

    Full Text Available Abstract Background Anesthesia is indispensable for in vivo research but has the intrinsic potential to alter study results. The aim of the current study was to investigate the impact of three common anesthesia protocols on physiological parameters and outcome following the most common experimental model for subarachnoid hemorrhage (SAH, endovascular perforation. Methods Sprague-Dawley rats (n = 38 were randomly assigned to (1 chloral hydrate, (2 isoflurane or (3 midazolam/medetomidine/fentanyl (MMF anesthesia. Arterial blood gases, intracranial pressure (ICP, mean arterial blood pressure (MAP, cerebral perfusion pressure (CPP, and regional cerebral blood flow (rCBF were monitored before and for 3 hours after SAH. Brain water content, mortality and rate of secondary bleeding were also evaluated. Results Under baseline conditions isoflurane anesthesia resulted in deterioration of respiratory parameters (arterial pCO2 and pO2 and increased brain water content. After SAH, isoflurane and chloral hydrate were associated with reduced MAP, incomplete recovery of post-hemorrhagic rCBF (23 ± 13% and 87 ± 18% of baseline, respectively and a high anesthesia-related mortality (17 and 50%, respectively. Anesthesia with MMF provided stable hemodynamics (MAP between 100-110 mmHg, high post-hemorrhagic rCBF values, and a high rate of re-bleedings (> 50%, a phenomenon often observed after SAH in humans. Conclusion Based on these findings we recommend anesthesia with MMF for the endovascular perforation model of SAH.

    Painless dental treatment is of major interest in pediatric dentistry. Local anesthesia contains epinephrine, which prolongs soft tissue anesthesia.This, however, is often a source of iscomfort for children and is responsible for certain side effects (e.g., self-inflicted soft tissue lesions). The aim of this study was to investigate whether an epinephrine-reduced articaine solution could reduce the duration of soft tissue anesthesia and thereby reduce the risk of self-inflicted soft tissue lesions, while still providing an adequate anesthesia. In a non-interventional clinical study, routine dental treatment was performed on children and adolescents. An articaine 4% solution with an epinephrine-reduced solution (Ubistesin™ mite, 1:400,000) and a conventional epinephrine solution (Ubistesin™ forte, 1:100,000) were compared in terms of duration of soft tissue anesthesia. One hundred and fifty-eight patients (mite: 75, forte: 83) were treated (80% with infiltration anesthesia). In both groups, the average volume of the injection was comparable (mite: 1.2 ml, forte: 1.1 ml). One patient from each group showed unwanted side effects. In both groups, the local anesthesia was complete or sufficient (96%) to perform the planned treatment. The average treatment time was 24 minutes in the mite group and 28 minutes in the forte group. The difference in mean duration of soft tissue anesthesia was statistically significant (p = 0.001, mite: 2.1 h, forte: 2.8 h). Thanks to its high efficacy, tolerance, and reduced soft tissue anesthesia, the articaine 4% solution with the reduced epinephrine concentration (1:400,000) was considered a safe and suitable drug for routine treatments in pediatric dentistry.

The long buccal nerve anesthesia in akinosi technique (75% was significantly higher than that of conventional technique. There was no significant difference between the two techniques for the depth of anesthesia. The success rate was 87.5% in conventional technique and 80% in akinosi technique. The average time of lips anesthesia in conventional technique was 3 minutes compared with 4 minutes in akinosi technique, which was not significantly different from each other. However, the beginning time of aneshtesia in tongue was significantly lower in conventional technique. No significant difference in the duration of anesthesia in lips and tonques between the two techniques was observed.

    Full Text Available In obstetrics postoperative cognitive dysfunctions may take place after caesarean section and vaginal delivery with poor results both for mother and child. The goal was to study influence of anesthesia techniques following caesarian section on memory, perception and speech. Having agreed with local ethics committee and obtained informed consent depending on anesthesia method, pregnant women were divided into 2 groups: 1st group (n=31 had spinal anesthesia, 2nd group (n=34 – total intravenous anesthesia. Spinal anesthesia: 1.8-2.2 mLs of hyperbaric 0.5% bupivacaine. ТIVА: Thiopental sodium (4 mgs kg-1, succinylcholine (1-1.5 mgs kg-1. Phentanyl (10-5-3 µgs kg-1 hour and Diazepam (10 mgs were used after newborn extraction. We used Luria’s test for memory assessment, perception was studied by test “recognition of time”. Speech was studied by test "name of fingers". Control points: 1 - before the surgery, 2 - in 24h after the caesarian section, 3 - on day 3 after surgery, 4 - at discharge from hospital (5-7th day. The study showed that initially decreased memory level in expectant mothers regressed along with the time after caesarean section. Memory is restored in 3 days after surgery regardless of anesthesia techniques. In spinal anesthesia on 5-7th postoperative day memory level exceeds that of used in total intravenous anesthesia. The perception and speech do not depend on the term of postoperative period. Anesthesia technique does not influence perception and speech restoration after caesarean sections.

    The authors relate their experience of 61 inhalation anesthesia of children from 5 months to 15 years years old. Head-tent is usually employed for intensive care as a method to administrate pure oxygen. Children are often afraid of the face-mask and tolerate head-tent easier. Three different protocols were studied: Nitrous oxide and oxygen mixture at different level (50 p. cent oxygen, 50 p. cent nitrous-oxide; or 30 p. cent oxygen, 70 p. cent nitrous oxide). The authors also used halothan in the inhalated mixture. The rebreathing level of CO2 in the head-tent according to the gas flow was measured. No incident, nor accident are related. This new anesthetic apparatus is easy to use, well accepted by children.

  18. Sufentanil citrate: a new opioid analgesic for use in anesthesia.

    Science.gov (United States)

    Rosow, C E

    1984-01-01

    Sufentanil citrate is a potent analogue of fentanyl that has been evaluated primarily for use in opioid anesthesia. It is a pure mu receptor agonist and produces the typical spectrum of opioid effects. The major side effects are truncal rigidity and prolonged respiratory depression. In doses of 4-30 micrograms/kg sufentanil produces hypnosis and suppresses most hemodynamic and hormonal responses to surgery without producing significant cardiovascular depression. In this respect sufentanil and fentanyl have clear advantages over morphine, meperidine and potent inhalation anesthetics. Compared to fentanyl, sufentanil has a more rapid onset and shorter duration of action. The relatively high concentration of commercially available sufentanil injection will make it much more convenient for its intended application than fentanyl injection. This new agent will be used primarily for open-heart surgery and major operations in patients with severe cardiovascular compromise.

    Phentolamine mesylate, at dosages from 0.4 to 0.8 mg in adults and adolescents and at dosages from 0.2 to 0.4 mg in children aged 4 to 11 years, has been proven to be safe and effective for the reversal of soft tissue anesthesia (lip and tongue numbness) and the associated functional deficits resulting from a local dental anesthetic injection containing a vasoconstrictor. Its ability to block a-adrenergic receptors on blood vessels induces vasodilation and enhances the redistribution of the local anesthetic away from the injection site. The low dosages administered for dental local anesthetic reversal in all likelihood accounts for the lack of significant cardiovascular effects that are associated with the medical use of the drug for hypertensive conditions associated with catecholamine excess.

    Full Text Available Objective. Reporting of a rare case of postoperative submandibular gland swelling following craniotomy. Case Report. A 33-year-old male underwent resection for a brain tumor under general anesthesia. The tumor was resected via a retrosigmoid suboccipital approach and the patient was placed in a lateral position with his face down and turned to the right. Slight swelling of the right submandibular gland was observed just after the surgery. Seven hours after surgery, edematous change around the submandibular gland worsened and he required emergent reintubation due to airway compromise. The cause of submandibular gland swelling seemed to be an obstruction of the salivary duct due to surgical positioning. Conclusion. Once submandibular swelling and edematous change around the submandibular gland occur, they can worsen and compromise the air way within several hours after operation. Adequate precaution must be taken for any predisposing skull-base surgery that requires strong cervical rotation and flexion.

    Full Text Available Background: Cardiovascular disease is an important non-obstetric cause of maternal and fetal /neonatal morbidity and mortality during pregnancy. For a pregnant woman with cardiac disease, the potential inability of the maternal cardiovascular system to contend with normal pregnancy-induced physiologic changes may produce deleterious effects on both mother and fetus. To determine the most frequent surgical indications of maternal and fetal mortality, we studied 15 cases of severe cardiac disease in pregnant women who required cardiac surgical procedures. Methods: In this descriptive study, fifteen pregnant women who underwent cardiac surgery were studied. Maternal age ranged from 27 to 36 years, and gestational age varied from 4 to 22 weeks. Most of the patients were in New York Heart Association Classes II and III. Opioid- based anesthesia with fentanyl citrate (50µ/kg or sufentanil (5µ/kg plus low dose of thiopental were used for the induction of anesthesia. During non-pulsatile cardio-pulmonary bypass, core temperature was between 28-36 °C, average CBP time was 61.2±22 min, average aortic cross-clamp time was 34.13±14 min, and mean pump pressure was maintained between 65-80 mmHg. Results: Ten patients had severe mitral valve disease (66.6%, three had aortic valve disease (20%, one had subvalvular aortic stenosis (6.7%, and the remaining one had left atrial myxoma (6.7%. There were five fetal deaths (33.3% and one maternal death (6.7%. Conclusion: It seems that open heart surgery in the first trimester is very hazardous for the fetus and may lead to fetal death. If possible, surgery should be carried out in the second trimester of pregnancy. The recommendations are simply guidelines because research data and clinical experience in this area are limited.

    Full Text Available La meningitis post-punción es una importante complicación de la anestesia espinal. Describimos el caso de un varón de cuarenta y seis años que ingresó para tratamiento quirúrgico de una hernia umbilical, la cirugía se realizó bajo anestesia intradural. Tras la intervención el paciente comenzó con un cuadro clínico compatible con meningitis, que se confirmó tras examen del líquido cefalorraquídeo. Se trató con antibióticos a pesar de la no identificación de gérmenes, siendo la evolución favorable. El diagnóstico etiológico de una meningitis iatrogénica no siempre es posible, pero siempre debemos tener en cuenta esta posibilidad. En este artículo queremos revisar la situación actual del problema, especialmente la profilaxis y la actitud terapéutica.Post-dural puncture meningitis is a serious complication of spinal anesthesia. We describe the case of a forty six years old male who was admitted for surgical intervention of an umbilical hernia, performed under spinal anesthesia. After surgery the patient developed a clinical syndrome compatible with meningitis, the diagnosis was confirmed by examination of the cerebrospinal fluid. Broad-spectrum antibiotics were started although spinal cultures were negatives, and the patient's clinical course was favourable. The meningitis differential diagnosis may be difficult, but we must think about this possibility. In this case report ,we want to check the present situation, specially the prevention and medical treatment.

    Full Text Available Aims and Objectives: Percutaneous MitraClip implantation has been demonstrated as an alternative procedure in high-risk patients with symptomatic severe mitral regurgitation (MR who are not suitable (or denied mitral valve repair/replacement due to excessive co morbidity. The MitraClip implantation was performed under general anesthesia and with 3-dimensional transesophageal echocardiography (TEE and fluoroscopic guidance. Materials and Methods: Peri-operative patient data were extracted from the electronic and paper medical records of 21 patients who underwent MitraClip implantations. Results: Four MitraClip implantation were performed in the catheterization laboratory; remaining 17 were performed in the hybrid operating theatre. In 2 patients, procedure was aborted, in one due to migration of the Chiari network into the left atrium and in second one, the leaflets and chords of the mitral valve torn during clipping resulting in consideration for open surgery. In the remaining 19 patients, MitraClip was implanted and the patients showed acute reduction of severe MR to mild-moderate MR. All the patients had invasive blood pressure monitoring and the initial six patients had central venous catheterization prior to the procedure. Intravenous heparin was administered after the guiding catheter was introduced through the inter-atrial septum and activated clotting time was maintained beyond 250 s throughout the procedure. Protamine was administered at the end of the procedure. All the patients were monitored in the intensive care unit after the procedure. Conclusions: Percutaneous MitraClip implantation is a feasible alternative in high-risk patients with symptomatic severe MR. Anesthesia management requirements are similar to open surgical mitral valve repair or replacement. TEE plays a vital role during the MitraClip implantation.

    2014-01-01

    Existing literature on learning in regional anesthesia broadly covers the rate of skill acquisition and the structure of educational programs. A complementary body of literature spanning psychology to medical education can be found describing skill acquisition in other fields. Concepts described in this literature have direct application to the teaching of regional anesthesia. This review introduces a selection of these complementary educational concepts, applying them to ultrasound-guided regional anesthesia skills education. Key educational concepts presented in this article can be divided into 3 sections, namely, how residents acquire manual skills, how tutors teach, and type of feedback.

    Full Text Available Lichtenstein inguinal hernia repair was described in 1974 by Irving Lichestein, who proposed a free tension surgical treatment. Currently this technique is performed anesthetic spinal block. However, many studies marke benefits of local anesthesia: prolonged postoperative analgesia, inexpensive, easy to perform and safe in patients at high risk. A retrospective observational study was performed. The inguinal hernia repair with only local anesthesia is a feasible technique, with similar results regarding recurrence. It has no specific complications of spinal anesthesia. Performed a randomized missing on costs, pain and quality of life postoperatively prospective analysis

    Cardiac arrest during anesthesia and perioperative period is a matter of grave concern for any anesthesiologist. But such mishaps have been reported for one reason or the other in the literary sciences. We are reporting the occurrence of unanticipated delayed cardiac arrest following spinal anesthesia in two young and healthy patients. Fortunately, these patients were successfully resuscitated with timely and appropriate cardiopulmonary resuscitative measures. Occurrence of such cases needs timely reporting and exploring all the possible causes of these unusual and possibly avoidable events. The present case reports are an important addition to a series of recently published mishaps that occurred during spinal anesthesia in young and healthy patients.

    Results. Plasma IL-6 level significantly increased with time similarly in both groups. No significant plasma IL-8 and IL-10 change was observed in both experimental groups. The VAS pain score was significantly lower in the awake group compared to the anesthesia group at 12 hours postoperative. Postoperative anxiety and stress declined similarly in both groups. Conclusion. This study suggests that awake function-controlled craniotomy does not cause a significantly different inflammatory response than craniotomy performed under general anesthesia. It is also likely that function-controlled craniotomy does not cause a greater emotional challenge than tumor resection under general anesthesia.

    Interest in global health to provide safer pediatric surgical care in developing countries has increased during the last decade. A collaborative effort between surgeons and anesthesiologists has provided the opportunity to deliver specialized care to children, particularly in the areas of cleft lip and palate repair. However, medical resources, facilities, and adequately trained personnel, especially in pediatric anesthesia, are often limited in these countries. Challenges, educational efforts, and future directions for the globalization of anesthesia are discussed. Involvement of international entities may help raise awareness, channel efforts, expand programs and encourage volunteerism to ultimately provide safer care to pediatric patients, have better outcomes and reduced anesthesia-related morbidity and mortality.

    2014-01-01

    Full Text Available Anesthesia dolorosa is an uncommon deafferentation pain that can occur after traumatic or surgical injury to the trigeminal nerve. This creates spontaneous pain signals without nociceptive stimuli. Compression of the trigeminal nerve due to acoustic neuromas or other structures near the cerebellopontine angle (CPA can cause trigeminal neuralgia, but the occurrence of anesthesia dolorosa subsequent to acoustic tumor removal has not been described in the medical literature. We report two cases of acoustic neuroma surgery presented with anesthesia dolorosa along the trigeminal nerve distribution. The patients’ pain was managed with multidisciplinary approaches with moderate success.

    In Germany, Austria and Switzerland, anesthesiologists are the second largest group of physicians in hospitals, but this does not correspond to the amount of anesthesiology teaching that medical students receive in medical schools. Accordingly, the chances of medical students recognizing anesthesiology as a promising personal professional career are smaller than in other disciplines with large teaching components. Subsequent difficulties to recruit anesthesiology residents are likely, although many reasons support anesthesiology as a professional career.Traditional strategies to teach medical students in anesthesiology in medical school consist of airway management or cardiopulmonary resuscitation attempts in manikins. Anesthesiology is a complex interaction consisting of anatomy, physiology, pharmacology, clinical evaluation, experience, knowledge, and manual skills. While some medical schools offer teaching in high fidelity simulators, clinical teaching in the operating room is often limited. When medical students opt for a clinical rotation in anesthesiology, there is a chance to demonstrate the fascinating world of anesthesiology, but this chance has to be utilized carefully by anesthesiologists, as young talents have to be discovered, supported, and challenged.We have put together a short guide for medical students for a clinical rotation in anesthesiology in adults in order to generate basic knowledge and interest in anesthesiology as well as a sense of achievement. Basic knowledge about premedication, induction, maintenance and strategies for anesthesia is discussed. Further, the most important anesthesia drugs are discussed and manual skills, such as intravenous cannulation, mask ventilation, intubation, and regional anesthesia are featured with QR-code based video illustrations on a smartphone or personal computer. We did not discuss possible local mannerism and special patient groups (e. g., children, special medical history), local guidelines

    Directory of Open Access Journals (Sweden)

    Christopher Uhlig

    Full Text Available This study aimed to investigate the quality of reporting of anesthesia and euthanasia in experimental studies in small laboratory mammals published in the top ten impact factor journals.A descriptive systematic review was conducted and data was abstracted from the ten highest ranked journals with respect to impact factor in the categories 'Anesthesiology', 'Critical Care Medicine' and 'Respiratory System' as defined by the 2012 Journal Citation Reports. Inclusion criteria according to PICOS criteria were as follows: 1 population: small laboratory mammals; 2 intervention: any form of anesthesia and/or euthanasia; 3 comparison: not specified; 4 primary outcome: type of anesthesia, anesthetic agents and type of euthanasia; secondary outcome: animal characteristics, monitoring, mechanical ventilation, fluid management, postoperative pain therapy, animal care approval, sample size calculation and performed interventions; 5 study: experimental studies. Anesthesia, euthanasia, and monitoring were analyzed per performed intervention in each article.The search yielded 845 articles with 1,041 interventions of interest. Throughout the manuscripts we found poor quality and frequency of reporting with respect to completeness of data on animal characteristics as well as euthanasia, while anesthesia (732/1041, 70.3% and interventions without survival (970/1041, 93.2% per se were frequently reported. Premedication and neuromuscular blocking agents were reported in 169/732 (23.1% and 38/732 (5.2% interventions, respectively. Frequency of reporting of analgesia during (117/610, 19.1% and after painful procedures (38/364, 10.4% was low. Euthanasia practice was reported as anesthesia (348/501, 69%, transcardial perfusion (37/501, 8%, carbon dioxide (26/501, 6%, decapitation (22/501, 5%, exsanguination (23/501, 5%, other (25/501, 5% and not specified (20/501, 4%, respectively.The present systematic review revealed insufficient reporting of anesthesia and euthanasia

    Full Text Available BACKGROUND: We investigated the effects of a novel method of anesthesia combining propofol and volatile anesthesia on the incidence of postoperative nausea and vomiting in patients undergoing laparoscopic gynecological surgery. METHODS: Patients were randomly divided into three groups: those maintained with sevoflurane (Group S, n = 42, propofol (Group P, n = 42, or combined propofol and sevoflurane (Group PS, n = 42. We assessed complete response (no postoperative nausea and vomiting and no rescue antiemetic use, incidence of nausea and vomiting, nausea severity score, vomiting frequency, rescue antiemetic use, and postoperative pain at 2 and 24 h after surgery. RESULTS: The number of patients who exhibited a complete response was greater in Groups P and PS than in Group S at 0-2 h (74%, 76% and 43%, respectively, p = 0.001 and 0-24 h (71%, 76% and 38%, respectively, p < 0.0005. The incidence of nausea at 0-2 h (Group S = 57%, Group P = 26% and Group PS = 21%, p = 0.001 and 0-24 h (Group S = 62%, Group P = 29% and Group PS = 21%, p < 0.0005 was also significantly different among groups. However, there were no significant differences among groups in the incidence or frequency of vomiting or rescue antiemetic use at 0-24 h. CONCLUSION: Combined propofol and volatile anesthesia during laparoscopic gynecological surgery effectively decreases the incidence of postoperative nausea. We term this novel method of anesthesia "combined intravenous-volatile anesthesia (CIVA".

    Background: Shivering is a common postanesthesia adverse event with multiple etiologies. At present tramadol is a widely used drug for the control of shivering. However, tramadol may cause a lot of nausea and vomiting. Hence, the need to find a better drug with less of side effects. The aim of this study was to compare the efficacy of dexmedetomidine and tramadol in the treatment of post-spinal anesthesia (SA) shivering as well as to compare their side-effect profile. Materials and Methods: This prospective, double-blind, randomized controlled trial was conducted in a tertiary care hospital. A total of 100 patients having shivering after SA were enrolled, out of which fifty received dexmedetomidine (Group A) and 50 received tramadol (Group B). The response rate, time to cessation of shivering and side effects (if any) was noted. All the results were analyzed using Student's t-test and Chi-square test. Results: All patients who received dexmedetomidine as well as tramadol had cessation of shivering. The time to cessation of shivering was significantly less with dexmedetomidine (174.12 ± 14.366 s) than with tramadol (277.06 ± 23.374 s) (P tramadol (16%). Nausea and vomiting was found to be higher in the case of tramadol. On the other hand, dexmedetomidine caused moderate sedation (modified Ramsay sedation score = 3–4) from which the patient could be easily awoken up. Conclusion: Dexmedetomidine offers better results than tramadol with fewer side effects. PMID:28217045

    Anesthesia information management systems (AIMS) are increasingly being implemented throughout the United States. However, little information exists on the implementation process for AIMS within ambulatory surgery centers (ASC). The objectives of this descriptive study are to document: 1) the phases of implementation of an AIMS at an ASC; and 2) lessons learnt from a socio-technical perspective. The ASC, within the Veterans Health Administration (VHA), has hosted an AIMS since 2008. As a quality improvement effort, we implemented a new version of the AIMS. This new version involved fundamental software changes to enhance clinical care such as real-time importing of laboratory data and total hardware exchange. The pre-implementation phase involved coordinated preparation over six months between multiple informatics teams along with local leadership. During this time, we conducted component, integration, and validation testing to ensure correct data flow from medical devices to AIMS and centralized databases. The implementation phase occurred in September 2014 over three days and was successful. Over the next several months, during post-implementation phase, we addressed residual items like latency of the application. Important lessons learnt from the implementation included the utility of partnering early with executive leadership; ensuring end user acceptance of new clinical workflow; continuous testing of data flow; use of a staged rollout; and providing additional personnel throughout implementation. Implementation of an AIMS at an ASC can utilize methods developed for large hospitals. However, issues unique to an ASC such as limited number of support personnel and distinctive workflows must be considered.

    Two paired randomized trials testing topical anesthesia with a eutetic mixture of local anesthetics (EMLA cream*) in vasectomy were performed. In 1 trial EMLA cream was applied on 1 side of the scrotum, while infiltration anesthesia into the skin and subcutaneous tissue with mepivacaine was used...... on the contralateral side. All but 1 of the 13 patients (p less than 0.05) preferred infiltration anesthesia because of pain as the incision reached the subcutaneous tissue. In the other trial 29 patients received EMLA cream on 1 side of the scrotum before bilateral mepivacaine infiltration. There was significantly...... less pain on the sides with the anesthetic cream (p less than 0.001). Many patients would pay the price of the cream. In conclusion, EMLA cream cannot replace but it can supplement infiltration anesthesia during vasectomy....

    Full Text Available There are many factors contributing to success of regional anesthesia. Patients’ attitude toward spinal anesthesia is one of the most important of these factors. This is a descriptive study performed on 100 healthy parturient selected for elective cesarean section in Alzahra Obstetric Hospital,Tabriz, Iran. The aim of this study was to evaluate patients’ attitude and their knowledge about spinal anesthesia. Patients were selected randomly. Data collection was performed using a questionnaire. Statistical programs used were Student’s t test and Chi square for demographic characteristics. The most important factors which influenced patients’ attitude were nausea and vomiting (27%, fear of pain (34%, fear of needle puncture (15% and discomfort during return of sensory and motor functions (6%. Being awake during surgery and witnessing birth of neonate were the most pleasant stages of anesthesia (19%. It seems that providing enough and appropriate information about the procedure at preoperative visit can increase acceptance of this regional anesthetic technique.

    Full Text Available Caudal epidural anesthesia in children is not performed in pure form, but only in combination with superficial general anesthesia. Therefore, a search for reliable evaluation criteria of the caudal epidural block onset in children remains actual. Aim. To evaluate effectiveness of caudal epidural anesthesia efficacy by measurement of feet skin temperature in children. Methods and results. We investigated feet skin temperature before the caudal blockade by bupivacaine and after 15–20 minutes in 30 children. The control group included 20 children who underwent total intravenous anesthesia. The study showed that feet skin temperature after caudal blockade significantly increased from 30,1±0,15°C to 33,0±0,1°C (10% and in the control group it did not change significantly. Conclusion. Thus, feet skin thermometry may be considered to be a reliable non-invasive method for assessing the onset of the caudal block.

    and the widespread use of the term "stress free anesthesia" in surgery is therefore not valid. However, continuous administration of local anesthetic agents in the epidural space is the most effective technique in so far as reduction of the stress response is concerned. The clinical implication of a variable...... reduction in the stress response to surgery by different anesthetic techniques remains largely unsettled, since only few controlled studies have been published on the clinical effects of pain relief and general anesthesia. However, a vast amount of data exist from controlled studies comparing regional...... anesthesia with local anesthetics and general anesthesia.

    Full Text Available Marc SnoeckDepartment of Anaesthesia, Canisius-Wilhelmina Hospital, Nijmegen, The NetherlandsAbstract: Articaine is an intermediate-potency, short-acting amide local anesthetic with a fast metabolism due to an ester group in its structure. It is effective with local infiltration or peripheral nerve block in dentistry, when administered as a spinal, epidural, ocular, or regional nerve block, or when injected intravenously for regional anesthesia. In comparative trials, its clinical effects were not generally significantly different from those of other short-acting local anesthetics like lidocaine, prilocaine, and chloroprocaine, and there is no conclusive evidence demonstrating above-average neurotoxicity. Articaine proved to be suitable and safe for procedures requiring a short duration of action in which a fast onset of anesthesia is desired, eg, dental procedures and ambulatory spinal anesthesia, in normal and in special populations.Keywords: articaine, regional anesthesia, pharmacodynamics, pharmacokinetics, therapeutic use, tolerability, neurotoxicity

    BACKGROUND Despite the high frequency of hypotension during spinal anesthesia with proper sedation, no previous report has compared the hemodynamic effects of dexmedetomidine and midazolam sedation during spinal anesthesia. We compared the effects of bispectral index (BIS)-guided intravenous sedation using midazolam or dexmedetomidine on hemodynamics and recovery profiles in patients who underwent spinal anesthesia. MATERIAL AND METHODS One hundred and sixteen adult patients were randomly assigned to receive either midazolam (midazolam group; n=58) or dexmedetomidine (dexmedetomidine group; n=58) during spinal anesthesia. Systolic, diastolic, and mean arterial pressures; heart rates; peripheral oxygen saturations; and bispectral index scores were recorded during surgery, and Ramsay sedation scores and postanesthesia care unit (PACU) stay were monitored. RESULTS Hypotension occurred more frequently in the midazolam group (Pmidazolam sedation.

    2012-10-01

    Full Text Available The balance between excitation and inhibition is considered to be of significant importance for neural computation and cognitive function. Excitatory and inhibitory functional connectivity in intact cortical neuronal networks in wakefulness and graded levels of anesthesia has not been systematically investigated. We compared monosynaptic excitatory and inhibitory spike transmission probabilities using pairwise cross-correlogram analysis. Spikes were measured at 64 sites in the visual cortex of rats with chronically implanted microelectrode arrays during wakefulness and three levels of anesthesia produced by desflurane. Anesthesia decreased the number of active units, the number of functional connections, and the strength of excitatory connections. Connection probability (number of connections per number of active unit pairs was unaffected until the deepest anesthesia level, at which a significant increase in the excitatory to inhibitory ratio of connection probabilities was observed. The results suggest that the excitatory-inhibitory balance is altered at an anesthetic depth associated with unconsciousness.

    2007-01-01

    Objective: To observe the advantage of total intravenous anesthesia for transurethral resection of bladder tumor (TURBT). Methods: Sixty ASA Ⅰ-Ⅱ patients undergoing TURBT were randomly assigned to 2 groups. Spinal anesthesia with 0.75% pure bupivacaine (8-12 mg) was applied to patients in Group Ⅰ (n= 30). Patients in Group Ⅱ (n=30) received total intravenous anesthesia with continuous infusion of Propofol and Remifentanil; and a laryngeal mask was used to ensure the airway and ventilation. BP, HR, SPO2 and pertinent side effects were monitored and recorded. Results: The patients in group Ⅱ experienced more stable hemodynamics than those in group Ⅰ. Obturator nerve reflex was observed in 15 (50.0%) patients in Group Ⅰ, but none (0%) in Group Ⅱ (P<0.01). Conclusion: Total intravenous anesthesia with laryngeal mask is a safe, reliable, controllable and simple manual for patient undergoing TURBT.

    The sitting beach-chair position is regularly used for shoulder surgery and anesthesia may be induced in that position. We tested the hypothesis that the cardiovascular challenge induced by induction of anesthesia is attenuated if the patient is placed in a reclining beach-chair position....... Anesthesia was induced with propofol in the sitting beach-chair (n = 15) or with the beach-chair tilted backwards to a reclining beach-chair position (n = 15). The last group was stepwise tilted to the sitting beach-chair position prior to surgery. Hypotension was treated with ephedrine.

    2008-01-01

    A 63-year-old woman with amyotrophic lateral sclerosis (ALS) was scheduled for open reduction and internal fixation of the right tibia. Total intravenous anesthesia using propofol and remifentanil without muscle relaxant was selected as the anesthetic method, in order to avoid the possible occurrence of ventilatory depression due to abnormal responses to muscle relaxants and exacerbation of the motor neuron disease. After standard and neuromuscular monitoring devices were applied, anesthesia was induced and maintained with target controlled infusion of propofol and remifentanil in the range of 2.5-5.0 microg x ml(-1) and 2.5-5.0 ng x ml(-1), respectively. To avoid delayed neuromuscular recovery, we did not use any muscle relaxant at all. Intubation was successful and there were no remarkable events during anesthesia, except for three brief hypotensive events; there was no exacerbation of ALS itself during or after the anesthesia. She was discharged on postoperative day 3, without any discomfort.

    Objective:To observe the effect of remifentanil combined with propofol anesthesia on stress response, blood gas index in patients with laparoscopic cholecystectomy. Methods:A total of 88 patients with laparoscopic cholecystectomy were randomly divided into the observation group (46 cases) and the control group (42 cases). After anesthesia induction,the observation group was given remifentanil combined with propofol intravenous anesthesia for continuous anesthesia, and control group was given isoflurane and propofol. Stress response (TNF-αα, CRP, BG, COGT), blood gas index (PaO2, PCO2, PH value) before surgery, before anesthesia maintained, and after surgery between two groups were compared. Results: Before anesthesia maintained and after surgery, PaO2 and PCO2 levels of the two groups increased with before surgery (P0.05). pH value of the two groups showed no change before and after surgery. Before anesthesia maintained and after surgery, TNF-αα, CRP, BG, COGT of the two groups increased with before surgery (P0.05) at before anesthesia maintained. While to the end of surgery, these index of the control group was significantly higher than that in the observation group (P<0.05). Conclusions:Remifentanil combined with propofol anesthesia can make blood gas index stable as well as isoflurane combined with propofol anesthesia, but inhibit stress response more significantly.

    Full Text Available Abstract Background Local anesthesia is widely used for open carpal tunnel release. However, injection of local anesthesia as described by Altissimi and Mancini (1988 can interfere with endoscopic carpal tunnel release, by increasing the bulk of synovial layers and consequently result in worsening of the view. Purpose The purpose of this study was to evaluate the safety, efficacy using modified technique for application of local anesthesia. Methods 33 patients suffering from gradual increasing symptoms of carpal tunnel syndrome. The patients were also asked to evaluate the pain associated with injection as well as tourniquet during surgery using Visual Analogue Scale (VAS (ranging from 0 = no pain to 10 = maximum pain. Results One patient required additionally local anesthesia because of mild pain in the hand. The tourniquet was inflated for 13.00 (2.8 min. The pain score related to injection was 2.5 (0.8 and to tourniquet was 3.6 (0.9. Inflation of the tourniquet was well tolerated by all patients. Postoperative neurological sensory and motor deficits related to surgery and local blocks were not occurred.

    Objective: To observe changes of plasma catecholamine (CA) level in patients experiencing cholecystectomy under acupuncture anesthesia combined with epidural administration of small dose of anesthetics. Methods:33 cholecystectomy patients were randomly divided into acupuncture combined with epidural anesthesia (A) group (n = 11), acupoint-skin electrical stimulation combined with epidural anesthesia (B) group (n= 11 ) and simple epidural anesthesia (C) group (n= 11). Acupoints used were bilateral Zusanli (ST 36) and Neiguan (PC 6) and stimulated with parameters of frequency 2/15 Hz, intermittent waves, electric current 2~3 mA for group A and 13mA for group B. Extradural anesthetic administered was 1.5% Lidocaine 5 mL. Venous blood samples were collected one day before,NE of group A and B lowered in comparison with pre-operation, particularly group A (P <0.01), while in group C,plasma NE level increased slightly; plasma E of group A and B increased significantly compared with pre-operation (P levels recovered basically in comparison with those of one day before operation. It indicates that acupuncture or acupoint-skin electrical stimulation is capable of regulating sympathetic activity during epidural anesthesia. The anesthetic effec t has a closer relation with changes of plasma NE level rather than changes of plasma E or DA levels. C_onclusion:Acupuncture or acupoint-surface electrical stimulation combined with epidural anesthesia may be of reducing or releasing surgical operation generated stress response during cholecystectomy.

    Monitoring the depth of anesthesia using an electroencephalogram (EEG) is a major ongoing challenge for anesthetists. The EEG is a recording of brain electrical activity, and it contains valuable information related to the different physiological states of the brain. This study proposes a novel automated method consisting of two steps for assessing anesthesia depth. Initially, the sample entropy and permutation entropy features were extracted from the EEG signal. Because EEG-derived parameters represent different aspects of the EEG features, it would be reasonable to use multiple parameters to assess the effect of the anesthetic. The sample entropy and permutation entropy features quantified the amount of complexity or irregularity in the EEG data and were conceptually simple, computationally efficient and artifact-resistant. Next, the extracted features were used as input for an artificial neural network, which was a data processing system based on the structure of a biological nervous system. The experimental results indicated that an overall accuracy of 88% could be obtained during sevoflurane anesthesia in 17 patients to classify the EEG data into awake, light, general and deep anesthetized states. In addition, this method yielded a classification accuracy of 92.4% to distinguish between awake and general anesthesia in an independent database of propofol and desflurane anesthesia in 129 patients. Considering the high accuracy of this method, a new EEG monitoring system could be developed to assist the anesthesiologist in estimating the depth of anesthesia in a rapid and accurate manner.

    2014-08-01

    Full Text Available Purpose: Evaluate the magnitude of cyclotorsion during cataract surgery in patients with indication for intraocular toric lenses comparing the results after peribulbar and after topical anesthesia. Methods: This prospective study comprised 112 eyes that underwent cataract surgery with implantation of toric intraocular lens by topical anesthesia or peribulbar block. We estimated how many degrees of cyclotorsion occurred after topical anesthesia and peribulbar block with the patient in supine position. A tag was performed in the position of 180 degrees of the right eye and zero degrees of the left eye, with the patient seated. Afterwards, it was requested a change to the supine position and then a new dial in 180 and zero degrees respectively from right and left eye were made. Results: The current study demonstrated that patients submitted to cataract surgery with implantation of toriclens under local anesthesia showed approximately 6.89 degrees of incyclotorsion (82 eyes and 6.93 degrees of excyclotorsion (38 eyes and a mean of cyclotorsion of 6.91 degrees. Patients undergoing peribulbar block showed 5.68 degrees of incyclotorsion (73 eyes and 4.81 degrees of excyclotorsion (47 eyes and a mean of cyclotorsion of 4.92 degrees. Conclusion: Through the study we can see that the movement of incyclotorsion in patients undergoing peribulbar anesthesia was lower when compared to topical anesthesia. This is relevant since the greater the incyclotorsion, the lower the predictability of the surgery and the lower the chance of obtaining excellent results in the final refractometric.

    Peripheral arterial disease is an illness with a high prevalence in Europe and North America. The disease is associated with a significant impact on quality of life. Despite advanced medical and endovascular treatments, surgery is often indicated to prevent the consequences of ischemic injury. Usually, these patients do have significant comorbidities resulting in an increased risk for anesthesia-related complications. While general anesthesia is commonly used for the majority of the patients, local and regional anesthesia (RA) offer several possible advantages such as stable cardiovascular hemodynamic perioperative course, improved postoperative pain relief and prevention of chronic postsurgical pain syndromes. This review will discuss perioperative management, available evidence regarding general anesthesia and various regional anesthetic techniques for peripheral vascular surgery, and the current advises regarding anticoagulants and RA. No definitive conclusions can be drawn from the existing literature with respect to superiority of general or neuraxial anesthesia or even RA. Maybe the profits lie in the combination of techniques, a strategy, to overcome the risks of one and use the benefits of the other technique. From circumstantial evidence, it is most likely that the experience of the anesthetic and surgical team is one of the major determinants of perioperative complications independent from the individual anesthesia technique.

    The aim of this study was to evaluate the use of a local anesthesia (LA) simulation model in a facilitated small group setting before dental students administered an inferior alveolar nerve block (IANB) for the first time. For this pilot study, 60 dental students transitioning from preclinical to clinical education were randomly assigned to either an experimental group (N=30) that participated in a small group session using the simulation model or a control group (N=30). After administering local anesthesia for the first time, students in both groups were given questionnaires regarding levels of preparedness and confidence when administering an IANB and level of anesthesia effectiveness and pain when receiving an IANB. Students in the experimental group exhibited a positive difference on all six questions regarding preparedness and confidence when administering LA to another student. One of these six questions ("I was prepared in administering local anesthesia for the first time") showed a statistically significant difference (pStudents who received LA from students who practiced on the simulation model also experienced fewer post-injection complications one day after receiving the IANB, including a statistically significant reduction in trismus. No statistically significant difference was found in level of effectiveness of the IANB or perceived levels of pain between the two groups. The results of this pilot study suggest that using a local anesthesia simulation model may be beneficial in increasing a dental student's level of comfort prior to administering local anesthesia for the first time.

    Objective To compare the acceptability and effectiveness of topical and infiltration anesthesia for placement of mini-implants used as temporary anchorage devices. Methods The sample comprised 40 patients, 17 males and 23 females, whose mean age was 26 years old and who were all undergoing orthodontic treatment and in need for anchorage reinforcement. Mini-implants were bilaterally placed in the maxilla of all individuals, with infiltration anesthesia on one side and topical anesthesia on the other. These 40 patients completed two questionnaires, one before and another after mini-implant placement and pain was measured through a visual analog scale (VAS). The data collected were analyzed using descriptive statistics and the measurements of pain were compared by means of the non-parametric test of Mann-Whitney. Results It was found that 60% of patients felt more comfortable with the use of topical anesthesia for mini-implant placement; 72.5% of patients described the occurrence of pressure during placement of the anchorage device as the most unpleasant sensation of the entire process; 62.5% of patients felt more pain with the use of topical anesthesia. Conclusion It was concluded that patients had less pain with the use of infiltration anesthesia, and also preferred this type of anesthetic. PMID:24945517

    Full Text Available Eminectomy which is one of the popular and most effective treatments for habitual temporomandibular joint luxation was first described by Myrhaug in 1951. There are few reports which described eminectomy being performed under local anesthesia and conscious sedation. We present a case series of habitual luxation of the TMJ treated by eminectomy performed under local anesthesia and conscious sedation and general anesthesia. Five patients were examined and found to have recurrent luxation of the TMJ. The age of patients ranged from 18 to 93 years. Bilateral eminectomy of the TMJ was performed for two patients, and unilateral eminectomy was performed for three patients. Two were examined under intravenous propofol sedation and local anesthesia, while three patients were examined under general anesthesia. One patient died from ileus one month after surgery. The follow-up period except for the case that died from ileus ranged from 12 to 33 months. No recurrent dislocation of the TMJ has been identified. Based on our experience and two other series in the literature, eminectomy with sedation and local anesthesia can be considered and might be a good option in elderly patients.

    Materials and Methods: In a private rural medical college, 150 patients were selected prospectively for laparoscopic cholecystectomy, under low-pressure (8mmHg pneumoperitoneum and under spinal anesthesia over a span of one and a half years. Injection bupivacaine (0.5% was used for spinal anesthesia. All ports were made in a head-down position to avoid hypotension. Shoulder pain was managed by reassurance as well as by diverting the attention and sedation in a few cases. Results: We successfully performed the operations in 145 patients without major complications. Spinal anesthesia was converted to general anesthesia in five patients due to severe shoulder pain. Age varied between 21 and 75 years. Duration of operation time (skin to skin was between 40 and 80 minutes. Twenty-nine patients complained of right shoulder pain. Most of them were managed by reassurance from the anesthetist and a few needed an injection of fentanyl along with midazolam. Conclusion: Laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum is feasible and safe under spinal anesthesia. Incidence of postoperative shoulder pain and complications are comparable with laparoscopic cholecystectomy under general anesthesia. [Arch Clin Exp Surg 2012; 1(4.000: 224-228

    BACKGROUND During abdominal surgery under regional anesthesia, nausea may happen due to several contributing factors. This study compared the effects of ondansetron and dexamethasone on nausea and vomiting under spinal anesthesia. METHODS One hundred and twenty patients of 15 to 35 years old with ASA class I and II were enrolled. Before administering either ondansetron or dexamethasone, blood pressure and heart rate of the patients were recorded. The patients received 70 mg of 5% lidocaine for spinal anesthesia. Patients who received 6 mg of ondansetron were considered as group A, while group B received 8 mg of dexamethasone. The level of nausea and vomiting, blood pressure, heart rate and respiratory rate of each patient was measured at 1, 5, 10, 15 and 30 minutes after spinal anesthesia and during recovery (every 5 minutes). RESULTS There was a significant difference between nausea and vomiting between the two groups after spinal anesthesia within the first and fifth minutes. There was no significant difference between nausea and vomiting between the two groups within 10, 15 and 30 minutes and during recovery at 5, 10, 15 and 30 minutes. CONCLUSION Dexamethasone and ondansetron were shown to equally reduce the incidence of nausea and vomiting under spinal anesthesia and can be recommended as a good choice for prevention of nausea and vomiting during surgeries.

    Full Text Available Now a days IVRA is developed with use of double tourniquet and additive drugs like opioids, NSAIDS , muscle relaxants etc ., to minimize the intraoperative discomfort of surgery and tourniquet pain. Many additives can take care of the post - operative pain. Each additive has its own pros and cons. Tramadol is a synthetic opioid analgesic having additional local anesthetic propert y and effect in neurotransmitter reuptake. With this background we studied the injection Tramadol 50mg as additive in IVRA against control group. METHODOLOGY : All the selected patients are from ASA Grade 1 and 2 for surgical procedure of upper limb. We hav e excluded the cases which are contraindicated for tourniquet and patients who are uncooperative and allergic to drug used for study. All 50 patients are divided in two groups. Group 1 - 25 patients who receive Intravenous Regional Anesthesia with injection lignocaine 0.5% 40cc volume. Group 2 - 25 patients who receive Intravenous Regional Anesthesia with injection Tramadol 50mgand injection lignocaine 0.5% total40ccvolume.

    We developed a new method to measure the nerve conduction velocity of a single digital nerve. In 27 volunteers (27 hands), we separately stimulated each digital nerve on the radial and ulnar sides of the middle and ring fingers. A double-peaked potential was recorded above the median nerve at the wrist joint when either the radial-side nerve or the ulnar-side nerve of the middle finger was stimulated. The first peak of this potential had disappeared after the digital nerve was blocked under the stimulating electrodes, and the peak appeared again coinciding with the decrease of anesthesia. Shifting the stimulating electrodes on the digital nerve resulted in no significant difference in the peak conduction velocity. It is possible that each peak of the potential was attributable to conduction of an action potential along one of the two digital nerves. This new method allows the assessment of a single digital nerve, and may be clinically useful for assessing the rupture of a digital nerve and the sensory nerve action potentials in carpal tunnel syndrome.

    According to recent surveys performed in United States and India, anesthesia care providers were observed to have sired female offspring in a higher proportion than male offspring as their firstborn progeny; however, the reasons for the skew are not clear. Our hypothesis is that the underlying biological evidence may be elucidated by unraveling differences (if any) between the concentrations of X-bearing sperms and Y-bearing sperms in the semen samples obtained from males exposed to varied levels of anesthetics in their lifetimes. Therefore, the objectives of the envisaged study would be to conduct a three-stage investigative study on in-vitro human semen samples to determine (a) X-bearing sperms and Y-bearing sperms concentrations' ratio in male pediatric anesthesia care providers' semen samples, (b) changes in X-bearing sperms and Y-bearing sperms concentrations' ratios between the pre-rotation and post-rotation semen samples of male medical student volunteers/observers, and (c) changes in X-bearing sperms and Y-bearing sperms concentrations' ratios between the pre-operative and post-operative day-3 semen samples of male patients presenting for outpatient procedures under inhalational anesthesia. The expected outcomes would be (a) linear and positive correlation of the anesthetic gas usage (exposure) with increased X-bearing sperms/Y-bearing sperms ratio in post-anesthesia day 3 sample as compared to the baseline preoperative sample, (b) linear and positive correlation of the anesthetic gas usage (exposure) with increased X-bearing sperms/Y-bearing sperms ratio in post-rotation sample as compared to the baseline sample, and (c) observation of high X-bearing sperms/Y-bearing sperms ratio in the pediatric anesthesia care providers. In summary, effects (if any) of occupational or personal exposure to inhalational anesthetic gases on the X-bearing sperms and Y-bearing sperms ratio is a worthy project wherein lots of questions that have arisen over decades could find

    Background The long-term cognitive effects of general anesthesia are under intense scrutiny. Here we present 5 cases from 2 academic institutions to analyze some common features where the patient’s or the patient family member has made a request to address their concern on memory loss, Alzheimer’s disease and general anesthesia before surgery. Methods Records of anesthesia consultation separate from standard preoperative evaluation were retrieved to identify consultations related to memory loss and Alzheimer’s disease from the patient and/or patient family members. The identified cases were extensively reviewed for features in common. We used Google® (http://www. google.com/) to identify available online information using “anesthesia memory loss” as a search phrase. Results Five cases were collected as a specific preoperative consultation related to memory loss, Alzheimer’s disease and general anesthesia from two institutions. All of the individuals either had perceived memory impairment after a prior surgical procedure with general anesthesia or had a family member with Alzheimer’s disease. They all accessed public media sources to find articles related to anesthesia and memory loss. On May 2nd, 2011, searching “anesthesia memory loss” in Google yielded 764,000 hits. Only 3 of the 50 Google top hits were from peer-reviewed journals. Some of the lay media postings made a causal association between general anesthesia and memory loss and/or Alzheimer’s disease without conclusive scientific literature support. Conclusion The potential link between memory loss and Alzheimer’s disease with general anesthesia is an important preoperative concern from patients and their family members. This concern arises from individuals who have had history of cognitive impairment or have had a family member with Alzheimer disease and have tried to obtain information from public media. Proper preoperative consultation with the awareness of the lay literature can

    The objective of this study was to determine the prevalence, severity, and duration of postoperative pain in children undergoing general anesthesia for dentistry. This prospective cross-sectional study included 33 American Society of Anesthesiology (ASA) Class I and II children 4-6 years old requiring multiple dental procedures, including at least 1 extraction, and/or pulpectomy, and/or pulpotomy of the primary dentition. Exclusion criteria were children who were developmentally delayed, cognitively impaired, born prematurely, taking psychotropic medications, or recorded baseline pain or analgesic use. The primary outcome of pain was measured by parents using the validated Faces Pain Scale-Revised (FPS-R) and Parents' Postoperative Pain Measure (PPPM) during the first 72 hours at home. The results showed that moderate-to-severe postoperative pain, defined as FPS-R ≥ 6, was reported in 48.5% of children. The prevalence of moderate-to-severe pain was 29.0% by FPS-R and 40.0% by PPPM at 2 hours after discharge. Pain subsided over 3 days. Postoperative pain scores increased significantly from baseline (P < .001, Wilcoxon matched pairs signed rank test). Moderately good correlation between the 2 pain measures existed 2 and 12 hours from discharge (Spearman rhos correlation coefficients of 0.604 and 0.603, P < .005). In conclusion, children do experience moderate-to-severe pain postoperatively. Although parents successfully used pain scales, they infrequently administered analgesics.

    Full Text Available Introduction. Anisocoria indicates a difference in pupil diameter. Etiologies of this clinical manifestation usually include systemic causes as neurological or vascular disorders, and local causes as congenital iris disorders and pharmacological effects.Case Report. We present a case of a 47-year-old man, suffering from spastic tetraparesis. After the oral surgery under general anesthesia, the patient developed severe anisocoria: in particular, a ~4mm diameter increase of the left pupil compared to the right pupil.We performed Computed Tomography (CT in the emergency setting, Nuclear magnetic resonance (NMR of the brain and Magnetic Resonance Angiography of intracranial vessels. These instrumental examinations did not show vascular or neurological diseases. The pupils returned to their physiological condition (isocoria after about 180 minutes.Discussion and Conclusions. Literature shows that the cases of anisocoria reported during or after oral surgery are rare occurrences, especially in cases of simple tooth extraction. Anisocoria can manifest in more or less evident forms: therefore, it is clear that knowing this clinical condition is of crucial importance for a correct and timely resolution.

    Full Text Available Introduction & objective: One of the most important drawbacks of radial artery is its tendency toward spasm and one of the rare etiologies of that is recurrent blood sampling of the artery. Other causes are injection of drugs in artery in spite of vein, or using radial artery in cardiopulmonary bypass. Papaverine is a useful drug in vasospasm, but it must be used with special caution to avoid it's complications such as arrhythmia. Case: The patient was a 72 year old man with intestinal gangrene and peritonitis whom was operated in Al-Zahra hospital in 2008. During Laparatomy surgery, because of severe acidosis, blood sampling was done 3 times for blood gas analysis. After being taken to the recovery ward, no radial pulse was detectable in the patient's right hand and severe cyanosis in the same hand was seen. After inserting the arterial catheter in brachial artery, treatment with Papaverine, indications of recovery were seen. Conclusion: Despite the rarity of radial artery spasm during anesthesia, it is very dangerous situation, and anesthesiologist must try to prohibit and be able to manage this problem and have suitable drugs in the operation room.

    To evaluate the efficacy and safety of radiologic venous port placement in children under venous anesthesia. Between April 2009 and July 2011, 44 ports were implanted in 41 children (24 boys, 17 girls). The age of patients ranged from 9 months to 19 years (mean, 6.5 years) and their body weights ranged from 6.8 kg to 56.3 kg (mean, 23.2 kg). Right internal jugular vein access was used in 42 ports, right subclavian vein in 1, and left subclavian in 1. Durability and complications of port implantation were reviewed. The technical success rate was 100%. The catheter life was 10-661 days (mean 246 days). Two patients died during the follow-up period, 21 and 6 ports were removed at the end of treatment or as a result of complications, respectively. One port was removed and replaced by a Hickmann catheter. Three ports were explanted due to port-related sepsis, one due to a catheter kink, and two for unexplained fever or insertion site pain. The overall port-related infection was 3 cases (6.8%, 0.28/1000 catheter days). Venous port placement by interventional radiologists in children under intravenous sedation is relatively safe, with a high rate of technical success and low rate of complications.

  13. Regional anesthesia for the trauma patient: improving patient outcomes.

    Trauma is a significant health problem and a leading cause of death in all age groups. Pain related to trauma is frequently severe, but is often undertreated in the trauma population. Opioids are widely used to treat pain in injured patients but have a broad range of undesirable effects in a multitrauma patient such as neurologic and respiratory impairment and delirium. In contrast, regional analgesia confers excellent site-specific pain relief that is free from major side effects, reduces opioid requirement in trauma patients, and is safe and easy to perform. Specific populations that have shown benefits (including morbidity and mortality advantages) with regional analgesic techniques include those with fractured ribs, femur and hip fractures, and patients undergoing digital replantation. Acute compartment syndrome is a potentially devastating sequela of soft-tissue injury that complicates high-energy injuries such as proximal tibia fractures. The use of regional anesthesia in patients at risk for compartment syndrome is controversial; although the data is sparse, there is no evidence that peripheral nerve blocks delay the diagnosis, and these techniques may in fact facilitate the recognition of pathologic breakthrough pain. The benefits of regional analgesia are likely most influential when it is initiated as early as possible, and the performance of nerve blocks both in the emergency room and in the field has been shown to provide quality pain relief with an excellent safety profile.

    The Authors present their experience in the treatment of prostatic obstruction with bladder neck incision (TUIP) performed under local anesthesia. An Hulbert 6 Fr endoscopic needle is used to infiltrate the prostatic area submitted to TUIP with 200 mg of Lidocaine 2%. The TUIP was done with a single deep incision at 7 hours using a 24 Fr Iglesias resector with Collins device. 28 patients with an age range from 69 to 85 years (mean 74) affected by IPB in an obstructed fase were submitted to this procedure. Various parameters were achieved for the selection of the patients: urodynamic diagnosis of low urinary tract obstruction, prostatic volume less than 50 ml without important prostatic median lobe, high anesthesiological risk, absence of correlated vesical complications. A clinical follow up was done at 1-6 and 12 months. The results obtained showed a good compliance of the patients treated with satisfactory urodynamic patterns. The Authors conclude that this less invasive approach, in selected cases, is the treatment of choice not only for low invasivity and morbidity rate but also for the reduced time of catheterization, hospitalization and costs.

The specific objectives included (a determination of the levels of ischemia-modified albumin (IMA and cardiac troponin I (cTnI as markers of myocardial injury, (b effect on mortality, morbidity, duration of mechanical ventilation, length of Intensive Care Unit (ICU and hospital stay, incidence of arrhythmias, pacing, cardioversion, urine output, and serum creatinine. Methodology and Design: Prospective randomized clinical study. Setting: Operation room of a cardiac surgery center of a tertiary teaching hospital. Participants: Seventy-six patients in New York Heart Association classification II to III presenting electively for AVR for severe symptomatic AS. Interventions: Patients included in the study were randomized into two groups and subjected to either a desflurane-fentanyl based technique or total IV anesthesia (TIVA. Blood samples were drawn at preordained intervals to determine the levels of IMA, cTnI, and serum creatinine. Measurements and Main Results: The IMA and cTnI levels were not found to be significantly different between both the study groups. Patients in the desflurane group were found to had significantly lower ICU and hospital stays and duration of postoperative mechanical ventilation as compared to those in the TIVA group. There was no difference found in mean heart rate, urine output, serum creatinine, incidence of arrhythmias, need for cardioversion, and 30-day mortality between both groups. The patients in the TIVA group had higher mean arterial pressures on weaning off cardiopulmonary bypass as well as postoperatively in the ICU and recorded lower inotrope usage. Conclusion: The result of our study remains ambiguous regarding

    Full Text Available Ultra rapid opioid detoxification (UROD is one of the new methods of detoxification. This method of detoxification involves putting patients under general anesthesia and actively giving them opioid antagonists. The objective of this study was to evaluate effects of anesthesia duration in UROD on severity of withdrawal syndrome. Sixty addicted patients seeking UROD procedure assigned randomly to one of the 2hr, 4hr or 6hr anesthesia duration groups. Premedication and anesthesia procedure (induction and maintenance were the same for three groups. Detoxification was done for all patients with 50 mg oral naltroxane (prior to induction and 20 mg intravenous naloxane (8 mg/bolus and 12 mg/infusion. Blood pressure, heart rate and respiratory rate were automatically measured and recorded every 5 minutes. The severity of withdrawal syndrome was measured and recorded every one hour during anesthesia, 2hours post-anesthesia, and 12 and 24 hours following the induction of anesthesia according to the Wang Scale modified by Lomier (WSMBL. Patients aged 20-58 in three groups. Three cases experienced delirium after detoxification that lasted 24 hours in one. Severity of withdrawal syndrome in patients of groups 2, 4 and 6 hour were 8.7, 7.4 and 5.1 respectively during anesthesia and 12.3, 11.1 and 13.9 after 18 hours of anesthesia. Results of this study showed that, in standard settings, UROD is a safe method for detoxification and has low complications. The withdrawal symptoms during and after anesthesia are low. Shortening the duration of anesthesia has no affect on severity of withdrawal syndrome during and after anesthesia.

    Human breath contains an abundance of volatile organic compounds (VOCs). Analysis of breath VOC may be used for diagnosis of various diseases or for on-line monitoring in anesthesia and intensive care. However, VOC concentrations largely depend on the breath sampling method and have a large inter-individual variability. For the development of breath tests, the influence of breath sampling methods and study subject characteristics on VOC concentrations has to be known. Therefore, we investigated the VOC isoprene in 62 study subjects during anesthesia and 16 spontaneously breathing healthy volunteers to determine (a) the influence of artificial and spontaneous ventilation and (b) the influence of study subject characteristics on breath isoprene concentrations. We used ion molecule reaction mass spectrometry for high-resolution breath-by-breath analysis of isoprene. We found that persons during anesthesia had significantly increased inspiratory and end-expiratory isoprene breath concentrations. Measured isoprene concentrations (median [first quartile-third quartile]) were in the anesthesia group: 54 [40-79] ppb (inspiratory) and 224 [171-309] ppb (end-expiratory), volunteer group: 14 [11-17] ppb (inspiratory) and 174 [124-202] ppb (end-expiratory). Higher end-tidal CO(2) concentrations in ventilated subjects were associated with higher expiratory isoprene levels. Furthermore, inspiratory and end-expiratory isoprene concentrations were correlated during anesthesia (r = 0.603, p < 0.001). Multivariate analysis showed that men had significantly higher end-expiratory isoprene concentrations than women. Rebreathing of isoprene from the anesthesia machine possibly accounts for the observed increase in isoprene in the anesthesia group.
