    Fibrodysplasia ossificans progressiva (FOP) is a rare and debilitating genetic disorder of skeletal malformations and progressive heterotopic ossification. Flare-ups are episodic, with bone formation in skeletal muscle and connective tissue leading to ankylosis of major joints of the axial and appendicular skeleton. This report outlines the management of a patient with FOP who had ankylosis of the temporomandibular joint and progressive ossification of the neck structures. The patient underwent two different surgical and anesthetic procedures within a 10-year period to manage his oral pain. The authors compare the surgical techniques, osteotomy versus the more conservative buccal approach, anesthesia techniques, and conventional intubation versus sedated fiberoptic intubation. This report emphasizes the importance of a less invasive surgical technique and an appropriate anesthetic management that reduces the risks, cost, and morbidity associated with routine surgical management of patients with FOP.

    Background and Objective. Anxiety/pain are experiences that make dental treatment difficult for children, especially during the time of anesthesia. Hypnosis is used in pediatric clinical situations to modify thinking, behavior, and perception as well as, recently, in dentistry; therefore the aim of this study was to evaluate the effectiveness of hypnosis combined with conventional behavior management techniques during infiltration anesthetic. Methods. Anxiety/pain were assessed with the FLACC scale during the anesthetic moment, as well as heart rate variability and skin conductance before and during the anesthetic moment, between the control and experimental group. Results. A marginal statistical difference (p = 0.05) was found in the heart rate between baseline and anesthetic moment, being lower in the hypnosis group. No statistically significant differences were found with the FLACC scale or in the skin conductance (p > 0.05). Conclusion. Hypnosis combined with conventional behavior management techniques decreases heart rate during anesthetic infiltration showing that there may be an improvement in anxiety/pain control through hypnotic therapy.

    Full Text Available Peripartum cardiomyopathy is a rare cause of dilated cardiomyopathy in parturients, occurring in approximately one in 1000 deliveries, manifesting during the last few months or the first 5 months of the postpartum period. It can result in severe ventricular dysfunction during late puerperium. The major concern while managing these patients is to optimize fluid administration and avoid myocardial depression, while maintaining stable intraoperative hemodynamics. We present a case series of five parturients that were posted for elective cesarean section and managed successfully by the epidural volume extension technique.

    We evaluated and characterized several anesthetic induction protocols used to facilitate intubation and anesthetic maintenance with isoflurane in 7 adult ostriches and 1 juvenile ostrich. Induction protocols included IV administration of zolazepam/tiletamine, IV administration of diazepam/ketamine with and without xylazine, IV administration of xylazine/ketamine, IM administration of carfentanil or xylazine/carfentanil, and mask induction with isoflurane. General anesthesia was maintained with isoflurane in 100% oxygen for various procedures, including proventriculotomy (6 birds), tibial (1 bird) or mandibular (1 bird) fracture repair, and drainage of an iatrogenic hematoma (1 bird). Heart rate and respiratory rate varied greatly among birds. The arterial blood pressure values recorded from 6 of the birds during maintenance of general anesthesia were higher than values recorded for most mammalian species, but were comparable to values reported for awake chickens and turkeys.

    Parturients with super-morbid obesity, defined as body mass index greater than 50kg/m(2), represent a growing segment of patients who require anesthetic care for labor and delivery. Severe obesity and its comorbid conditions place the parturient and fetus at greater risk for pregnancy complications and cesarean delivery, as well as surgical and anesthetic complications. The surgical approach for cesarean delivery in these patients may require a supra-umbilical vertical midline incision due to a large pannus. The dense T4-level of spinal anesthesia can cause difficulties with ventilation for the obese patient during the procedure, which can be prolonged. Patients also may have respiratory complications in the postoperative period due to pain from the incision. We describe the anesthetic management of three parturients with body mass index ranging from 73 to 95kg/m(2) who had a cesarean delivery via a supra-umbilical vertical midline incision. Continuous lumbar spinal and low thoracic epidural catheters were placed in each patient for intraoperative anesthesia and postoperative analgesia, respectively. Continuous spinal catheters were dosed with incremental bupivacaine boluses to achieve surgical anesthesia. In one case, the patient required respiratory support with non-invasive positive pressure ventilation. Two cases were complicated by intraoperative hemorrhage. All patients had satisfactory postoperative analgesia with a thoracic epidural infusion. None suffered postoperative respiratory complications or postdural puncture headache. The use of a continuous lumbar spinal catheter and a low thoracic epidural provides several advantages in the anesthetic management of super-morbidly obese parturients for cesarean delivery.

  7. Anesthetic Techniques and Cancer Recurrence after Surgery

    Full Text Available Many of the most common anesthetics are used in surgical oncology, yet effects on cancer cells are still not known. Anesthesia technique could differentially affect cancer recurrence in oncologic patients undergoing surgery, due to immunosuppression, stimulation of angiogenesis, and dissemination of residual cancer cells. Data support the use of intravenous anesthetics, such as propofol anesthesia, thanks to antitumoral protective effects inhibiting cyclooxygenase 2 and prostaglandins E2 in cancer cells, and stimulation of immunity response; a restriction in the use of volatile anesthetics; restriction in the use of opioids as they suppress humoral and cellular immunity, and their chronic use favors angiogenesis and development of metastases; use of locoregional anesthesia compared with general anesthesia, as locoregional appears to reduce cancer recurrence after surgery. However, these findings must be interpreted cautiously as there is no evidence that simple changes in the practice of anesthesia can have a positive impact on postsurgical survival of cancer patients.

    Full Text Available Aplastic anemia is a rare heterogeneous disorder of hematopoietic stem cells causing pancytopenia and marrow hypoplasia with the depletion of all types of blood cells. This results in anemia, neutropenia and thrombocytopenia, which pose a challenge to both surgical and anesthetic management of such cases. We report a child with aplastic anemia who sustained traumatic ulcer on the arm and underwent split-thickness skin grafting under general anesthesia. There are only two case reports on anesthetic considerations in aplastic anemia patients in the literature. The anesthetic management is challenging because of the rarity of the disease, associated pancytopenia and immunosuppression.

  9. Anesthetic management of transcatheter aortic valve implantation

    Directory of Open Access Journals (Sweden)

    Annalisa Franco

    2012-01-01

    Full Text Available Transcatheter aortic valve implantation (TAVI is an emergent technique for high-risk patients with aortic stenosis. TAVI poses significant challenges about its management because of the procedure itself and the population who undergo the implantation. Two devices are currently available and marketed in Europe and several other technologies are being developed. The retrograde transfemoral approach is the most popular procedure; nevertheless, it may not be feasible in patients with significant aortic or ileo-femoral arterial disease. Alternatives include a transaxillary approach, transapical approach, open surgical access to the retroperitoneal iliac artery and the ascending aorta. A complementary approach using both devices and alternative routes tailored to the anatomy and the comorbidities of the single patient is a main component for the successful implementation of a TAVI program. Anesthetic strategies vary in different centers. Local anesthesia or general anesthesia are both valid alternatives and can be applied according to the patient′s characteristics and procedural instances. General anesthesia offers many advantages, mainly regarding the possibility of an early diagnosis and treatment of possible complications through the use of transesophageal echocardiography. However, after the initial experiences, many groups began to employ, routinely, sedation plus local anesthesia for TAVI, and their procedural and periprocedural success demonstrates that it is feasible. TAVI is burdened with potential important complications: vascular injuries, arrhythmias, renal impairment, neurological complications, cardiac tamponade, prosthesis malpositioning and embolization and left main coronary artery occlusion. The aim of this work is to review the anesthetic management of TAVI based on the available literature.

    Full Text Available The coexistence of hyperthyroidism with gestational trophoblastic disease is a known albeit rare clinical condition. We herein report the successful anesthetic management of such a case in our institute. There are only few case reports in literature of this association. Often, the diagnosis of hyperthyroid state is retrospective one, as it can be missed in the emergency scenario of patient requiring molar evacuation. This case report highlights the perioperative management and optimization of hyperthyroid state prior to surgical evacuation of the invasive hydatidiform mole.

    Awake craniotomy allows continuous monitoring of patients' neurological functions during open surgery. Anesthesiologists have to sedate patients in a way so that they are compliant throughout the whole surgical procedure, nevertheless maintaining adequate analgesia and anxiolysis. Currently, the use of α2-receptor agonist dexmedetomidine as the primary hypnotic-sedative medication is increasing. Nine patients undergoing awake craniotomy were treated with refined monitored anesthesia care (MAC) protocol consisting of a combination of local anesthesia without scalp block, low-dose infusion of dexmedetomidine, propofol, and remifentanil, without the need of airways management. The anesthetic protocol applied in our study has the advantage of decreasing the dose of each drug and thus reducing the occurrence of side effects. All patients had smooth and rapid awakenings. The brain remained relaxed during the entire procedure. In our experience, this protocol is safe and effective during awake brain surgery. Nevertheless, prospective randomized trials are necessary to confirm the optimal anesthetic technique to be used.

    Huntington's disease is a dominantly inherited progressive autosomal disease that affects the basal ganglia. Symptoms appear later in life and manifest as progressive mental deterioration and involuntary choreiform movements. Patients with Huntington's disease develop a progressive but variable dementia. Dysphagia, the most significant related motor symptom, hinders nutrition intake and places the patient at risk for aspiration. The combination of involuntary choreoathetoid movements, depression, and apathy leads to cachexia. Factors of considerable concern to the anesthesiologist who treats patients with Huntington's disease may include how to treat frail elderly people incapable of cooperation, how to treat patients suffering from malnourishment, and how to treat patients with an increased risk for aspiration or exaggerated responses to sodium thiopental and succinylcholine. The successful anesthetic management of a 65-yr-old woman with Huntington's disease who presented for full-mouth extractions is described.

    Anesthesia of the soft and hard tissues of the maxilla may require up to 5 injections. Thus, the aim of this study was to evaluate the anesthetic efficacy of the anterior middle superior alveolar (AMSA) and supraperiosteal injection techniques during subgingival scaling and root planing (SRP). Thirty individuals with periodontitis were scheduled for SRP on the buccal aspect of teeth in the anterior maxilla. Before SRP, on a randomly chosen side of the maxilla, the supraperiosteal injection was performed in 1 session, while the AMSA injection was conducted in the contralateral side of the same patient in another session. Immediately after each SRP session, patients rated their pain perception during the procedure with a visual analog scale. No statistically significant differences in mean pain ratings during SRP were found after both anesthetic techniques (P > .05). This preliminary study demonstrated that the AMSA and supraperiosteal injection techniques provided similar anesthetic comfort during SRP. The AMSA injection could be an alternative to anesthetize the buccal aspect of maxilla, without the undesirable effects on facial structures such as the upper lip, nostrils, and lower eyelids. However, further randomized clinical trials with larger samples are necessary to confirm such results. PMID:26650493

    Local anesthetic (LA) allergy is a concern for dermatologic surgeons given the large number of procedures performed yearly with LAs. Many patients also have anxiety about past or potential anesthesia allergy. This article will review the symptoms of IgE-mediated allergic reactions, the prevalence of IgE-mediated LA allergy, discuss common mimics of LA, and propose a practical approach for diagnostic and therapeutic options for LA allergy for the dermatologic surgeon in practice. A literature search of Pubmed using keywords "lidocaine," "local anesthetic," "hypersensitivity," and "allergy" was performed. Amide anesthetics result in the most reports of true local anesthetic immediate hypersensitivity. True IgE-mediated anaphylaxis to local anesthesia is very rare. Dermatologic surgeons should be aware of the symptoms of anesthetic allergy and its mimickers, as well as how to manage allergic reactions in their clinical practice.

  19. Anesthetic technique for inferior alveolar nerve block: a new approach

    2011-02-01

    Full Text Available BACKGROUND: Effective pain control in Dentistry may be achieved by local anesthetic techniques. The success of the anesthetic technique in mandibular structures depends on the proximity of the needle tip to the mandibular foramen at the moment of anesthetic injection into the pterygomandibular region. Two techniques are available to reach the inferior alveolar nerve where it enters the mandibular canal, namely indirect and direct; these techniques differ in the number of movements required. Data demonstrate that the indirect technique is considered ineffective in 15% of cases and the direct technique in 13-29% of cases. OBJECTIVE: The aim of this study was to describe an alternative technique for inferior alveolar nerve block using several anatomical points for reference, simplifying the procedure and enabling greater success and a more rapid learning curve. MATERIAL AND METHODS: A total of 193 mandibles (146 with permanent dentition and 47 with primary dentition from dry skulls were used to establish a relationship between the teeth and the mandibular foramen. By using two wires, the first passing through the mesiobuccal groove and middle point of the mesial slope of the distolingual cusp of the primary second molar or permanent first molar (right side, and the second following the oclusal plane (left side, a line can be achieved whose projection coincides with the left mandibular foramen. RESULTS: The obtained data showed correlation in 82.88% of cases using the permanent first molar, and in 93.62% of cases using the primary second molar. CONCLUSION: This method is potentially effective for inferior alveolar nerve block, especially in Pediatric Dentistry.

    Full Text Available Kimura′s disease is a rare form of chronic eosinophilic inflammatory disease with vascular proliferation involving salivary gland, skin, lymph node, and kidney. Important anesthetic concerns include increased surgical bleeding due to its vascular nature, airway involvement by the mass leading to a possible difficult airway, allergic symptoms associated with high eosinophil count and elevated IgE level and nephrotic syndrome due to involvement of kidney by the inflammatory process. There is paucity of information in the literature on the anesthetic management of Kimura′s disease. We describe the anesthesia technique and review the literature of such a case posted for superficial parotidectomy.

    The literature on the anesthetic management of parturients with dwarfism is sparse and limited to isolated case reports. Pregnancy complications associated with dwarfism include an increased risk of respiratory compromise, an increased risk of Cesarean delivery, and an unpredictable degree of anesthesia with neuraxial techniques. Therefore, we conducted this retrospective review to evaluate the anesthetic management of parturients with a diagnosis of dwarfism. We used a query of billing data to identify short statured women who underwent a Cesarean delivery during May 1, 2008 to May 1, 2013. We then hand searched the electronic medical record for qualifying patients with heights dwarfism. The extracted data included patient demographics and obstetric and anesthetic information. We identified 13 women with dwarfism who had 15 Cesarean deliveries in total. Twelve of the women had disproportionate dwarfism, and ten of the 15 Cesarean deliveries were due to cephalopelvic disproportion. Neuraxial anesthesia was attempted in 93% of deliveries. The dose chosen for initiation of neuraxial anesthesia was lower than the typical doses used in parturients of normal stature. Neuraxial anesthetic complications included difficult neuraxial placement (64%), high spinal (7%), inadequate surgical level (13%), and unrecognized intrathecal catheter (7%). The data collected suggest that females with a diagnosis of dwarfism may have difficult neuraxial placement and potentially require lower dosages of local anesthetic for both spinal and epidural anesthesia to achieve adequate surgical blockade.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a chronically progressing or relapsing disease caused by immune-mediated peripheral neuropathy. We report the anesthetic management of three CIDP patients who underwent elective orthopedic surgeries. Owing to the risk of neuraxial anesthetics triggering demyelination, general anesthesia was selected to avoid epidural or spinal anesthesia or other neuraxial blockade. It was also judged prudent to avoid prolonged perioperative immobilization, which might compress vulnerable peripheral nerves. For Patient 1, general anesthesia was induced with propofol, remifentanil, and sevoflurane, and was maintained with sevoflurane and remifentanil. For Patients 2 and 3, general anesthesia was induced and maintained with propofol and remifentanil. For tracheal intubation, under careful monitoring with peripheral nerve stimulators, minimal doses of rocuronium (0.6-0.7 mg x kg(-1)) were administered. When sugammadex was administered to reverse the effect of rocuronium, all patients rapidly regained muscular strength. Postoperative courses were satisfactory without sequelae.

    Full Text Available Hunter′s syndrome is a member of a group of recessively inherited metabolic disorders termed mucopolysaccharidoses, caused by deficiency of lysosomal enzymes required for degradation of mucopolysaccharides or glycosaminoglycans, leading to accumulation of partially degraded glycosaminoglycans in various tissues. This leads to various anatomical abnormalities and systemic involvement, posing a challenge to an anesthetist. We present the anesthetic management of a 4-year old child with Hunter′s disease with anticipated difficult airway, who presented for adenotonsillectomy and repair of umbilical and inguinal hernia.

    Full Text Available Obstructing lesions of the central airways present with a variety of symptoms and are often associated with pneumonia or asthma-like states. Anesthesia to these patients often presents challenges right from the preoperative stabilization of underlying lung condition, mask ventilation in the supine position to maintaining oxygenation and ventilation in the intraoperative and postoperative period. We present here a case of a young woman with a central bronchial tumor with significant airway obstruction with potential for major bleeding and subsequent anesthetic management without lung sacrificing measures and cardiopulmonary bypass assistance.

    A 74-year-old male was operated for sigmoid colon cancer. Because of an agglutination of the patient's platelet, it was difficult to measure his platelet count under ethylene diamine tetra acetate (EDTA), heparin or citrate as anticoagulants with an automated cell counter. Even though there was a strong possibility of pseudothrombocytopenia, anesthetic management for the patient was safely conducted. His condition was stable throughout the perioperative course and no bleeding tendency was observed. Nitrous oxide, oxygen, sevoflurane, propofol and pancuronium were useful in this case.

    Full Text Available Schwannoma arising from the base of the tongue are very rare and only a few cases have been reported so far. Definitive diagnosis is always made after a histological examination. Apart from an anticipated difficult airway with a risk of airway obstruction upon induction of general anesthesia, anesthetic concerns also include possibility of trauma to the growth and bleeding with attendant risks. We discuss the awake fiberoptic technique used for endotracheal intubation in such a case. This case report highlights the importance of detailed history taking and clinical examination, with emphasis on airway assessment and preoperative planning.

    Objective To investigate clinical features of pheochromocytoma and summarize experiences of anesthetic management during the perioperative period. Methods Two hundred and fifty eight patients who were diagnosed with pheochromocytoma in our hospital were reviewed retrospectively for clinical features. According to different preoperative pharmalogical preparations, perioperative mortalities were analyzed in three periods (Period 1: January 1955-December 1975; Period 2: January 1976-December 1994; Period 3: January 1995-July 2001). In Period 3, hemodynamic changes in the patients undergoing different anesthetic methods were analyzed. Results About 5.8% (15/258) of pheochromocytoma was an integral part of multiple endocrine neoplasia (MEN) type Ⅱ or mixed type. Sixty percent (149/249) of the patients who had undergone surgery possessed evidence of catecholamine cardiac toxicity preoperatively. Impaired glucose tolerance was found in 59% (147/249) of the patients before surgery. Perioperative mortality was significantly decreased from 8% (5/60) in Period 1 to 1.2% (1/75) in Period 2 (P<0.01). No perioperative deaths occurred in Period 3. The volume infused during the operation was significantly higher both in the epidural anesthesia group (3474 ml±624 ml, P<0.01) and in the epidural plus general anesthesia group (3654 ml±475 ml, P<0.01) than in the general anesthesia group (2534 ml±512 ml). There were favorable hemodynamic characteristics in patients before removal of the tumor in the epidural anesthesia group and in the epidural plus general anesthesia group, as compared with the general anesthesia group. Conclusions A positive surgical outcome of the excision of pheochromocytoma depends on multiple factors, including careful assessment of potential vital organ damage before surgery and restoration of blood volume by establishing α-blockade preoperatively, meticulous anesthetic management of patients during surgery, and appropriate circulatory support after

    Full Text Available Myasthenia gravis (MG is a rare disorder involving neuromuscular junction. In conjunction with medical therapy, thymectomy is a known modality of treatment of MG and has shown to increase the probability of remission and overall symptomatic improvement. For minimally invasive thymectomy, video-.assisted thoracoscopic surgery has been the preferred surgical approach till recently. The robotic surgical procedure must necessarily bring new challenges to the anesthesiologists to effectively meet the specific requirements of the technique. At present, there is a paucity of literature regarding the anesthetic concerns of robotic assisted thymectomy, patient in question specifically posed a challenge since different maneuvers and techniques had to be tried to obtain optimum surgical conditions with stable ventilatory and hemodynamic parameters. Concerns of patient positioning and hemodynamic monitoring have also been discussed.

    Full Text Available Hereditary spherocytosis (HS is a familial hemolytic disorder with marked heterogeneity of clinical features ranging from asymptomatic condition to a fulminant hemolytic anemia. HS is characterized by the strong family history of anemia, jaundice, splenomegaly and cholelithiasis. Anesthetic Management of HS with liver dysfunction is very challenging since most of the anesthetic drugs are metabolized by the liver. Hereby, we report anesthetic management in a case of HS with splenomegaly and gall stones for elective splenectomy and cholecystectomy.

    Adult onset congenital diaphragmatic hernia (CDH) is uncommon but not rare. Morgagni hernia is a rare variant of CDH. The defect tends to be small and patients may remain asymptomatic and diagnosed incidentally. When these patients become symptomatic, they usually present with gastrointestinal and cardiorespiratory symptoms or sometimes as an emergency due to obstruction or strangulation of herniated viscera. Chest radiograph, computed tomography scan, and magnetic resonance imaging are the imaging modalities used for diagnosis of CDH. Cardiopulmonary compromise due to mass effect of hernial contents on lungs, heart and great vessels, and obstruction or strangulation of herniated viscera poses the special challenge before anesthesiologists. Our patient was diagnosed to have Morgagni hernia, at the age of 72 years and underwent laparotomy for the same. This case highlights the key feature of the successful anesthetic management of adult onset CDH.

    2015-01-01

    Full Text Available Carcinoid tumors are rare, slow-growing neoplasms of neuroendocrine tissues from enterochromaffin or kulchitsky cells, which have the potential to metastasize. The mediators released from these tumors when bypass the hepatic metabolism, can lead to the possible development of carcinoid syndrome. This is a life-threatening complication, which can lead to profound hemodynamic instability, especially in a peri-operative period, when the patient is exposed to various types of noxious stimuli. Off late, use of octreotide, a synthetic analog of somatostatin, has significantly reduced the peri-operative morbidity and mortality. The current review discusses the various anesthetic challenges and considerations during peri-operative management of carcinoid tumors.

    Transversus abdominal plane (TAP) block is a known and useful technique, widely used for postoperative pain management of abdominal wall incisions. During the past years, and following the expansion of ultrasound guided techniques, its use has even gained more adepts. It is usually used as an adjuvant technique, primarily in order to control postoperative pain and reduce opioids consumption. We report the case of an 82 years old patient admitted for drainage of a postoperative abdominal wall hematoma after correction of a McBurney incisional hernia. The corrective surgery had gone on without incident, under general anesthesia with laryngeal mask. Two weeks later, the patient came back to our emergency department with a clear hematoma of the abdominal wall. Surgery was decided. A sole local anesthetic technique was achieved, using a TAP block. The block was performed under ultrasound guidance, using a subcostal approach. The surgery went on without complications. Therefore, TAP block offers a hemodynamic stability, appropriate intra-operative anesthesia and post-surgical analgesia of the abdominal wall.

    Full Text Available Background & Objective: Administration of anesthetic substances to chickens requires careful consideration for the safe delivery of the agent to the bird. The research objective was to evaluate several drug combinations for intramuscular anesthesia in chickens for physiologic, nutritional, pharmacological and other investigations. Meterial & Methods: Sixty healthy chickens were randomly assigned in six treatment groups and received Ketamine in combination with Xylazine, Midazolam or Acepromazine. Heart and respiratory rate, induction time, duration of surgical anesthesia and light anesthesia were measured. Results: Induction of anesthesia was significantly longer following Acepromazine- Ketamine and Midazolam- Ketamine compared to other groups (P<0.05. Duration of surgical anesthesia was longest with Xylazine- Midazolam- Ketamine and shortest with Midazolam-Ketamine and Acepromazine- Ketamine (P<0.05. Conclusion: In conclusion, the most effective drug combinations resulting in longer duration of surgical anesthesia, were Xylazine- Acepromazine- Ketamine and Xylazine- Midazolam- Ketamine. Other combinations did not produce appropriate surgical anesthesia, but they make slight changes in physiological data.

  5. Severe preeclampsia: anesthetic implications of the disease and its management.

    Preeclampsia is a significant, multifactorial, multiorgan disease affecting 6%-8% of all pregnancies in the United States and is the third leading cause of maternal mortality. As such, it is incumbent upon any anesthesia provider involved in obstetric cases to be familiar with the varied manifestations of the disease, management goals from an obstetric standpoint, and the implications for provision of anesthesia in this patient group. Despite improvements in the diagnosis and management of preeclampsia, severe complications can occur in both the mother and the fetus. A systematic approach to the anesthetic evaluation is therefore necessary to reduce morbidity and mortality and to improve outcomes. The potential pitfalls of general anesthesia, including failed intubation, in these complicated patients make regional anesthesia the preferred choice in many cases. Recent studies have shown that spinal anesthesia is often appropriate for preeclamptic patients, even in severe cases. Nevertheless, it is important to be aware of the potential contraindications to neuraxial anesthesia and to prepare for the possibility of encountering a difficult airway.

    Full Text Available Congenital lobar emphysema (CLE is a potentially reversible, though life-threatening cause of respiratory distress in neonates. It is a rare developmental anomaly of the lower respiratory tract. A 10-month-old child presented with fever, cough and difficulty in breathing. Respiratory system examination revealed tachypnea with intercostal retraction, decreased breath sounds over the left upper lobe and room air saturation of 95%. Chest radiograph and computed tomography showed hyperinflated left upper zones with mediastinal shift. Left thoracotomy, followed by left upper lobectomy was performed under general anesthesia with one lung ventilation. Oxygen saturation, blood pressure, electrocardiogram and capnogram were continuously monitored. During anesthesia, conventionally positive pressure ventilation is avoided until the diseased lobe is isolated, however we adopted gentle manual ventilation maintaining the airway pressure before thoracotomy as described by Cotι and Payne et al. Successful anesthetic management of CLE can be achieved by proper understanding of pathophysiology, good perioperative monitoring, and adopting novel management strategies.

    Full Text Available Arginase deficiency is an autosomal recessive disorder of the urea cycle in which a defect in conversion of arginine to urea and ornithine leads to hyperammonemia. Patients with urea cycle disorders may show increased protein catabolism due to inadequate intake of energy, protein and essential amino acids; infections, fever and surgery. A 12-year-old girl with arginase deficiency, ASA II who weighed 40 kg was scheduled for bilateral adductor, quadriceps and gastrocnemius tenotomies. She had mental retardation, spasticity and flexion posture of thelower limbs. Metabolic homeostasis was restored with appropriate diet. Successful anesthetic management allowed the patient to be discharged 48 hours after surgery. Increased levels of arginine and ammonia during or after surgery may lead to serious complications such as hypotension, cerebral edema, convulsions, hypothermia and spasticity. Thus special attention must be given to metabolic homeostasis and nutrition of the patients with arginase deficiency in the perioperative period. Primary goals should be to minimize stress levels by effective anxiolysis, provide an adequate amount of protein-free energy with proper fluid management and to obtain an effective preemptive and postoperative analgesia. In addition to a high level of knowledge, successful anesthesia requires professional communication among nursing staff, dietitians, pediatric metabolism specialist, surgeon and anesthesiologist.

    Full Text Available ABSTRACT The anesthetic management of patients with large mediastinal masses can be complicated due to the pressure effects of the mass on the airway or major vessels. We present the successful anesthetic management of a 64-year-old female with a large mediastinal mass that encroached on the great vessels and compressed the trachea. A tracheal stent was placed to relieve the tracheal compression under general anesthesia. Spontaneous ventilation was maintained during the perioperative period with the use of a classic laryngeal mask airway. We discuss the utility of laryngeal mask airway for anesthetic management of tracheal stenting in patients with mediastinal masses.

    Full Text Available Abstract Background and objectives: Multiple sclerosis is a demyelinating disease of the brain and spinal cord, characterized by muscle weakness, cognitive dysfunction, memory loss, and personality disorders. Factors that promote disease exacerbation are stress, physical trauma, infection, surgery, and hyperthermia. The objective is to describe the anesthetic management of a case referred to urological surgery. Case report: A female patient, 44 years of age, with multiple sclerosis, diagnosed with nephrolithiasis, referred for endoscopic ureterolythotripsy. Balanced general anesthesia was chosen, with midazolam, propofol and remifentanil target-controlled infusion; sevoflurane via laryngeal mask airway; and spontaneous ventilation. Because the patient had respiratory difficulty presenting with chest wall rigidity, it was decided to discontinue the infusion of remifentanil. There was no other complication or exacerbation of disease postoperatively. Conclusion: The use of neuromuscular blockers (depolarizing and non-depolarizing is a problem in these patients. As there was no need for muscle relaxation in this case, muscle relaxants were omitted. We conclude that the combination of propofol and sevoflurane was satisfactory, not resulting in hemodynamic instability or disease exacerbation.

    2010-09-01

    Full Text Available Acute intermittent porphyria is a rare metabolic disorder resulting from a partial deficiency of porphobilinogen deaminase, enzyme in the heme biosynthetic pathway. Its inheritance is autosomal dominant. A deficiency of porphobilinogen deaminase is not sufficient by its self to produce acute intermittent porphyria, and other activating factors must also be present. These include some drugs, hormones, infection, injury and alcohol. Besides others, anesthetics have been implicated in the triggering of a number of severe porphyric reactions. Although there is no clinical evidence, the fear of hypothesized porphyrinogenicity of repetitive anesthetics exposures still remains. Despite these doubts, we report here the case of uneventful repeated exposure to anesthetics in a patient suffering from acute intermittent porphyria, within a fifteen- month period. On both occasions, the patient was safely exposed to certain anesthetics included: propofol, sevoflurane, rocuronium, midazolam and fentanyl.

    The purpose of our study was to determine the effects of anesthetic technique and ambient temperature on thermoregulation for patients undergoing lower extremity surgery. Our study included 90 male patients aged 18-60 years in American Society of Anesthesiologists Physical Status groups I or II who were scheduled for lower extremity surgery. Patients were randomly divided into three groups according to anesthetic technique: general anesthesia (GA), epidural anesthesia (EA), and femoral-sciatic block (FS). These groups were divided into subgroups according to room temperature: the temperature for group I was 20-22 °C and that for group II was 23-25 °C. Therefore, we labeled the groups as follows: GA I, GA II, EA I, EA II, FS I, and FS II. Probes for measuring tympanic membrane and peripheral temperature were placed in and on the patients, and mean skin temperature (MST) and mean body temperature (MBT) were assessed. Postoperative shivering scores were recorded. During anesthesia, tympanic temperature and MBT decreased whereas MST increased for all patients. There was no significant difference between tympanic temperatures in either the room temperature or anesthetic method groups. MST was lower in group GA I than in group GA II after 5, 10, 15, 20, 60 and 90 min whereas MBT was significantly lower at the basal level (p thermoregulation among anesthetic techniques. Room temperature affected thermoregulation in Group GA.

    Full Text Available A 35-year-old male with pan-anterior urethral stricture was scheduled to undergo perineal urethrostomy. He was a known case of Kindler′s syndrome since infancy. He was having a history of blister formation, extensive poikiloderma and progressive cutaneous atrophy since childhood. He had a tendency of trauma-induced blisters with clear or hemorrhagic contents that healed with scarring. The fingers were sclerodermiform with dystrophic nails and inability to completely clench the fist. Airway examination revealed thyromental distance of 7 cm with limited neck extension, limited mouth opening and mallampatti class III with a fixed large tongue. He was reported as grade IV Cormack and Lehane laryngoscopic on previous anesthesia exposure. We described the anesthetic management of such case on guidelines for epidermolysis bullosa. In the operating room, an 18-G cannula was secured in the right upper limb using Coban TM Wrap. The T-piece of the cannula was than inserted into the slit and the tape was wrapped around the extremity. The ECG electrodes were placed on the limbs and fixed with Coban TM . Noninvasive blood pressure cuff was applied over the wrap after wrapping the arm with Webril® cotton. Oral fiberoptic tracheal intubation was done after lubricating the laryngoscope generously with a water-based lubricant with 7-mm endotracheal tube. Surgery proceeded without any complication. After reversing the residual neuromuscular block, trachea was extubated once the patient became awake. He was kept in the postanesthesia care unit for 2 hours and then shifted to urology ward.

    2016-01-01

    Modern spirometry, like no other monitoring technique, allows insight into breath-to-breath respiratory mechanics. Spirometers continuously measure volume, airway pressure, and flow while calculating and continuously displaying respiratory system compliance and resistance in the form of loops. The aim of this case series is to show how observation of spirometric loops, similar to electrocardiogram or CO2 curve monitoring, can improve safety of anesthetic management in small animals. Spirometric monitoring cases described in this case series are based on use of the anaesthesia monitor Capnomac Ultima with a side stream spirometry sensor. The cases illustrate how recognition and understanding of spirometric loops allows for easy diagnosis of iatrogenic pneumothorax, incorrect ventilator settings, leaks in the system, kinked or partially obstructed endotracheal tube, and spontaneous breathing interfering with intermittent positive-pressure ventilation. The case series demonstrates the potential of spirometry to improve the quality and safety of anesthetic management, and, hence, its use can be recommended during intermittent positive-pressure ventilation and procedures in which interference with ventilation can be expected.

    This case involves a possible complication of excessive bleeding or rupture of hemangiomas. Problems and anesthetic management of the patient are discussed. A 35-year-old man with Sturge-Weber syndrome was to undergo teeth extraction and gingivectomy. Hemangiomas covered his face and the inside of the oral cavity. We used intravenous conscious sedation with propofol and N2O-O2 to reduce the patient's emotional stress. It was previously determined that stress caused marked expansion of this patient's hemangiomas. Periodontal ligament injection was chosen as the local anesthesia technique. Teeth were extracted without excessive bleeding or rupture of hemangiomas, but the planned gingivectomies were cancelled. Deep sedation requiring airway manipulation should be avoided because there are possible difficulties in airway maintenance. Because this was an outpatient procedure, propofol was selected as the sedative agent primarily because of its rapid onset and equally rapid recovery. Periodontal ligament injection with 2% lidocaine containing 1: 80,000 epinephrine was chosen for local anesthesia. Gingivectomy was cancelled because hemostasis was challenging. As part of preoperative preparation, equipment for prompt intubation was available in case of rupture of the hemangiomas. The typically seen elevation of blood pressure was suppressed under propofol sedation so that expansion of the hemangiomas and significant intraoperative bleeding was prevented. Periodontal ligament injection as a local anesthetic also prevented bleeding from the injection site.

    2014-02-01

    Full Text Available AbstractThere is a little experience of anesthetic management of patients with radiocontrast induced nephropathy (RCIN. We report anesthetic management of a 75 years-old, diabetic male patient who underwent off-pump CABG surgery with the diagnosis of RCIN following coronary angiography. The treatment of RCIN is limited. Thus supportive approach should be performed while awaiting the recovery of the impaired renal functions. Protracted period of recovery and the deterioration of the patient’s clinical situation, forced us for immediate revascularization. Off-pump CABG was the preferred technique of surgery. Postoperative period was uneventful and patient was discharged. Although waiting for spontaneous resolving of the nephropathy is mostly recommended, Off-pump CABG with balanced anesthesia may be performed safely on patients with RCIN if the patients’ cardiac complaints become worse.

    Non-obstetric diseases during pregnancy are not uncommon. The presence of systemic disease may further insult the pregnancy leading to alteration in the normal function of other system. Hence, it is important to treat the disease depending upon the severity and type of urgency. Several systemic diseases in pregnancy and management have been reported earlier but it is necessary to report a rare pathology, treatment option and its anesthetic management. We report anesthetic management of a rare case of pseudo pancreatic cyst in a pregnant lady operated for cysto-gastrostomy and also highlighting the recent guidelines for non-obstetric surgery in pregnancy.

    Full Text Available Background: Complete obstruction of the abdominal aorta at the renal artery level is a difficult surgical problem. Aortic clamping and declamping can lead to profound haemodynamic changes, myocardial infarction, ventricular failure or even death may result. These complications are important challenges in anesthetic management of these patients. Methods :0 Between August, 2010 and April, 2012, descending thoracic aorta to femoral artery bypass grafting was used to revascularize lower limbs in 11 patients in our institute. The anesthetic management of these patients is described here. Epidural catheter placement was done in T 5-6 or T 6-7 space for post operative pain relief. Induction was done by, Inj. Glycopyrolate 0.2 mg, Inj. Fentanyl 5 μg/kg., Inj. Pentothal sodium 5 mg/kg, Inj. Rocuronium 0.9 mg/kg, IPPV done. Left sided double lumen tube was inserted, Maintenance of Anesthesia was done by O 2 + N 2 O (30:70. Increments of Vecuronium and Fentanyl were given Monitoring of Heart rate, arterial pressure, central venous pressure were continuously displayed. The available pharmacological agents were used when there is deviation of more than 15% from base line. Results: In our study, inspite of measures taken to control rise in blood pressure during aortic cross clamping, a rise of 90 mm of Hg in one patient and 60-80 mm of Hg in four patients was observed, which was managed by sodium nitropruside infusion. At the end of surgery seven patients were extubated on the operation table. In remaining four patients DLT was replaced by single lumen endotracheal tube and were shifted to ICU on IPPV. They weaned off gradually in 3-5 hours. In our series blood loss was 400 ml to 1000 ml. There was no mortality in the first 24 hours. Postoperative bleeding was reported in one case which was re-explored and stood well. Conclusion: The anesthetic technique during aortic surgery is directed at minimizing the hemodynamic effects of cross clamping in order to

    Neuroleptic malignant syndrome (NMS) is a rare disorder which is clinically similar to malignant hyperthermia (MH). It is characterized by hyperthermia, autonomic instability, muscle rigidity, coma, rhabdomyolysis, and acidosis. Without immediate and appropriate therapy, mortality may result. NMS is associated with administration of antipsychotic medications, anti-emetic medications, and changes in the dosage of anti-parkinsonian drugs. As several similarities exist between NMS and MH, differentiating between them can be a challenge for the clinician. We report anesthetic care during magnetic resonance imaging of the brain of a 14-year-old female with bipolar and schizoaffective disorders and the recent onset of NMS.

    Electroconvulsive therapy (ECT) remains an indispensable treatment for severe psychiatric illness. It is practiced extensively in the United States and around the world, yet there is little guidance for anesthesiologists involved with this common practice. Communication between the anesthesiologist and the proceduralist is particularly important for ECT, because the choice of anesthetic and management of physiologic sequelae of the therapeutic seizure can directly impact both the efficacy and safety of the treatment. In this review, we examine the literature on anesthetic management for ECT. A casual or "one-size-fits-all" approach may lead to less-than-optimal outcomes; customizing the anesthetic management for each patient is essential and can significantly increase treatment success rate and patient satisfaction.

    Full Text Available Arthrogryposis multiplex congenita is a rare disease, characterized by non-progressive, multiple joint contractures since birth. Anesthetic issues include difficult intravenous access, difficult airway management and regional anesthesia. We report the anesthetic management of a six-day-old neonate presenting to the emergency with features of intestinal obstruction, who was detected for the first time to have arthrogryposis multiplex congenita. General anesthesia along with caudal analgesia for peroperative and postoperative pain relief was used. There was an episode of intraoperative hyperthermia, which was tackled successfully. The child had an uneventful post-anesthesia recovery.

    Full Text Available Renal artery disease is the most common cause for surgically curable form of hypertension. In a small subset of patients with severe aortic disease where the aorta is not suitable for endovascular technique and to provide an arterial inflow, an extra-anatomic renal bypass surgery (EARBS is an option. Anesthetic management of such procedures has not been described so far in the literature. We retrospectively analyzed the anesthetic techniques used in all patients who underwent EARBS between February 1998 and June 2008 at this institute. We also further analyzed data concerning blood pressure (BP control and renal function response following surgery as outcome variable measures. A total of 11 patients underwent EARBS during this period. Five received oral clonidine with premedication. During laryngoscopy, esmolol was used in 4 patients, while lignocaine was used in remaining 7 patients. Of 11 patients, 7 showed significant hemodynamic response to laryngoscopy and intubation; among these, one had oral clonidine with premedicant, and 6 received lignocaine just before laryngoscopy. Intravenous vasodilators were used to maintain target BP within 20% of baseline during perioperative period. All patients received renal protective measures. During follow-up, 10% were considered cured, 70% had improved BP response, while 20% failed to show improvement in BP response. Renal functions improved in 54.5%, remain unchanged in 36.5%, and worsened in 9% of patients. Use of clonidine during premedication and esmolol before laryngoscopy were beneficial in attenuating hemodynamic response to laryngoscopy, while use of vasodilators to maintain target BP within 20% of baseline, and routine use of renal protective measures appear to be promising in patients undergoing EARBS.

    During routine deep sedation for endodontic therapy, a dentist-anesthesiologist observed premature ventricular contractions (PVCs) on a 62-yr-old woman's electrocardiogram (EKG) tracing. The dentist was able to complete the root canal procedure under intravenous (i.v.) sedation without any problems. The dentist-anesthesiologist referred the patient for medical evaluation. She was found to be free from ischemic cardiac disease with normal ventricular function. The patient was cleared to continue her dental treatment with deep sedation. She subsequently continued to undergo dental treatment with deep intravenous sedation without incident, although her EKG exhibited frequent PVCs, up to 20 per minute, including couplets and episodes of trigeminy. This article will review indications for medical intervention, antiarrhythmic medications, and anesthetic interventions for perioperative PVCs.

    Full Text Available Pheochromocytoma is a neuroendocrine tumor of the adrenal medulla chromaffin cells. It has a variable clinic indicating symptoms such as hypertension, headache, sweating, palpitations, and anxiety. Determination of vanillylmandelic acid in urine and metanephrines are accepted as the most sensitive tests for diagnosis. Computerized tomography and magnetic resonance imaging cad be used for tumor localization. Anesthetic induction and surgical manipulations usually lead to the catastrophic release of catecholamines. Thus, accurate preoperative pharmacological preparation is vital in these patients. Treatment is a complete surgical resection of the primary tumor and, if possible, metastases after banning dangerous fluctuations in hemodynamic through α-blockers. Today, laparoscopic adrenalectomy has begun to replace open surgery as a standard treatment method in many adrenal diseases. J Clin Exp Invest 2014; 5 (2: 443-446

    Transcatheter aortic valve implantation is an emergent technique for high risk patients with aortic stenosis. Transcatheter aortic valve implantation poses significant challenges about its management, due to the procedure itself (i.e. the passage of large stiff sheaths in diseased vessels, the valve dilatation and the prosthesis positioning during a partial cardiac standstill) and the population of elder and high-risk patients who undergo the implantation. Retrograde transfemoral approach is the most popular procedure and a great number of cases is reported. Nevertheless, there is not a consensus regarding the intraoperative anesthesiological strategies, which vary in the different Centers. Sedation plus local anesthesia or general anesthesia are both valid alternatives and can be applied according to patient's characteristics and procedural instances. Most groups started the implantation program with a general anesthesia; indeed, it offers many advantages, mainly regarding the possibility of an early diagnosis and treatment of potential complications, through the use of the transesophageal echocardiography. However, after the initial experiences, many groups began to employ routinely sedation plus local anesthesia for transcatheter aortic valve implantation and their procedural and periprocedural success demonstrates that it is feasible, with many possible advantages. Many aspects about perioperative anesthetic management for transcatheter aortic valve implantation are still to be defined. Aim of this work is to clarify the different management strategies through a review of the available literature published in pubmed till June 2011.

    Full Text Available Increasing numbers of adult patients with complex congenital heart conditions are presenting for noncardiac surgery later in life. These disorders can present challenges for surgical and anesthesia providers. Specifically, single ventricle lesions offer anatomic and physiologic concerns during the perioperative period. Single ventricle physiology represents a delicate balance between systemic and pulmonary blood flow. Any alterations in blood flow through these systems can produce undesirable hemodynamic changes, especially during the perioperative period. We present a case of an adult patient with a single left ventricle who presented for laparoscopic total colectomy due to inflammatory bowel disease. His abnormal anatomy coupled with the hemodynamic disruptions caused by laparoscopy presented significant anesthetic challenges. We highlight the anesthetic concerns of single ventricle physiology, specifically pertaining to laparoscopic surgery. We provide recommendations for safely managing these patients perioperatively. With detailed preoperative evaluation and close hemodynamic monitoring during the perioperative period, these patients can experience successful surgical and anesthetic outcomes.

    Data from the records of 142 patients for carotid endarterectomy at Chugoku Rosai General Hospital between 1983 and 1995, were evaluated concerning perioperative risk factors and anesthetic management. As a preoperative anesthetic risk, the incidence of hypertension was the commonest (76%), and there was a significant incidence of ischemic heart disease (18%). Fentanyl and isoflurane have been used for anesthesia recently and the patients were closely observed and cared in the intensive care unit postoperatively. In order to prevent cerebral ischemia during the occlusion of the internal carotid artery, we measured somatosensory evoked potential as well as jugular venous oxygen saturation, and used near infrared spectophotometry. As a result, postoperative mortality and morbidity were 0% and 2%, respectively. The candidates for CEA have potentially high perioperative risks, and it is important to evaluate the coexisting diseases and to select proper anesthetic technic and monitors.

    Wilsons disease, characterized by cirrhosis, extrapyramidal symptoms and Kayser-Fleischer corneal rings, is a rare hereditary disease of human copper metabolism. Clinical findings in Wilsons disease are complex and neurological symptoms such as tremor, dysarthria, rigid dystonia, seizures, psychiatric disorders, acute liver failure, chronic hepatitis or cirrhosis may develop. A 4-year-old male patient was operated for traumatic depressed skull fracture and intracerebral hematoma. He was diagnosed with Wilsons disease at the age of 2.5 years and treated with zinc sulphate and D-penicillamine. General anesthesia was induced with propofol, fentanyl, atracurium, and maintained with isoflurane, and oxygen. No complications were encountered during the operation or in the postoperative period. We concluded that general anesthesia can successfully be given to Wilsons disease patients using an anesthetic agent, the metabolism of which is least affected by the liver disease, one that induces least hepatic toxicity. By close follow-up of patients clinically and biochemically, it is possible to reduce the complication rates to a minimum.

    The current case report describes two cases of alkaptonuric ochronosis for anesthetic management. Alkaptonuria is a rare genetic orphan disease of tyrosine metabolism characterized by an accumulation of homogentisic acid in cartilage and connective tissues. Patients present most commonly for orthopedic joint surgery due to progressive arthropathy that can be misdiagnosed many a times. However respiratory, airway, cardiovascular and genitourinary systems complications can occur with age progressing. Restricted range of motion of cervical spine may lead to difficulty with airway management. In addition, degenerative changes and stiffness of lumbar spine due to ochronosis would make neuraxial blockade challenging. Although this inherited condition is extremely rare, anesthesiologists should be aware of its existence and prepare for management of potential challenging problems. This report highlights special care and precautions that need to be taken during anesthetic management. Copyright © 2016 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

Standard structured checklist developed by ECRI institute (Emergency Care Research Institute was applied. Checklists were filled onsite through direct observation and interviews with anesthesia personnel in 46 operating rooms at 4 hospitals from all of the hospitals under affiliation of Isfahan University of Medical Sciences. These hospitals were selected based on the number of surgical beds.Results: Total means score of WAGs risk management status was 1.72 from the scale of 3. In the studied operating rooms, only 28% complied with predetermined standards, 16% needed improvement and 56% had no compliance. Total mean scores of compliance in planning, training and evaluation and monitoring of waste anesthetic gases were weak and equipment and work activity was at medium level.Conclusion: The risk management status of waste anesthetic gases in the hospitals to be weak, therefore operating room personnel are exposed to medium to high level of these gases. The hospital mangers should prepare and apply scavenging equipment, development of control program, quality improvement, risk management and maintenance of anesthesia equipment. Finally, ongoing monitoring and evaluation, education to personnel and modification of policy and procedures and improvement of work activities should be considered.

This syndrome is characterized by epilepsy, central hypotonia, developmental delay and intellectual disability, and autistic behavior. This is the first report of the anesthetic management of a patient with this syndrome. We administered general anesthesia for dental treatment in a patient with 15q tetrasomy. Appropriate planning for the prevention of complications such as seizures and hypotonia, and for delayed emergence from anesthesia, is required. Specifically, choosing short-acting drugs that do not induce seizures, together with suitable monitoring, resulted in successful anesthetic management of the patient with 15q tetrasomy.

    Full Text Available Background: The most common technique to anesthetize mandibular primary teeth is inferior alveolar (I.A nerve block injection which induces a relatively sustained anesthesia and in turn may potentially traumatize soft-tissues. Therefore, the need of having an alternative technique of anesthesia with a shorter term but the same efficacy is reasonable. The aim of this study was a comparison of the efficacy of two anesthetic techniques of mandibular primary first molar. Materials and Methods: In this randomized crossover clinical trial, 40 children with ages ranged from 5 years to 8 years whose mandibular primary first molars were eligible for pulpotomy, were selected and divided randomly into two groups. The right and left mandibular first molars of group A were anesthetized with infiltration and I. A nerve block techniques in the first and second sessions respectively. The left and right mandibular first molars of group B were anesthetized with I.A nerve block and infiltration techniques in the first and second sessions respectively. The severity of pain were measured and recorded according to sound-eye-motor scale by a certain person. Data was analyzed using Wilcoxon Signed Rank and Mann-Whitney U tests (P < 0.05. Results: The severity of pain was lower in infiltration technique versus I.A nerve block. There were no significant differences between the severities of pain on pulpal exposure of two techniques. Conclusion: It seems that infiltration technique is more favorable to anesthetize the mandibular primary first molar compared to I.A nerve block.

    Preeclampsia is a pregnancy-associated illness affecting multiple organ systems. Symptoms typically occur after the 20th week of gestation and consist of hypertension (>140/90 mmHg) and proteinuria (>300 mg/day). It is one of the leading causes of premature birth worldwide and early diagnosis and treatment are essential for both fetal and maternal health. Therapy is aimed at lowering blood pressure sufficiently to prevent the most severe complications such as intracranial hemorrhages. At the same time attention must be paid to the possible untoward effects of blood pressure medications on uteroplacental perfusion and fetal well being. Magnesium is the cornerstone for both prevention and control of eclamptic cerebrovascular events. In cases of severe preeclampsia and eclampsia prompt delivery is indicated, often carried out by Cesarean section (>34 weeks of gestation). Compared to general anesthesia, regional anesthesia techniques offer certain advantages to both mother and fetus and in the absence of contraindications are the methods of choice.

    The stiff-person syndrome (SPS) is a rare autoimmune neurologic disorder that affects the gamma-aminobutyric acid (GABA) mediated inhibitory network in the central nervous system with anti-glutamic acid decarboxylase (GAD) antibodies. SPS is characterized by muscle rigidity and painful episodic spasms in axial and lower limb muscles. This case report describes successful peri-operative management of a 61-year-old female (height, 158 cm; weight, 60 kg, ASA-PS 2) with her right upper arm fracture who was scheduled for open reduction and internal fixation. This patient had bulbar paralysis, dysphagia and muscle rigidity associated with a high titer of anti-GAD auto antibodies (2,800 U x ml(-1)). She was diagnosed as SPS and has been treated with predonisolone (30 mg x day(-1)) and diazepam (20 mg x day(-1)) for 1 year. Predonisolone (15 mg) and diazepam (30 mg) was given orally before induction of general anesthesia with propofol, remifentanil and rocuronium bromide. Posture change from supine to beach-chair position led to sudden drop in blood pressure to 38/25 mmHg, which recovered promptly by injecting intravenous ephedrine hydrochloride (28 mg) and hydrocortisone (100 mg). Postanesthetic course was uneventful without postoperative neurologic abnormalities.

    We report a case of massive endobronchial hemorrhage after pulmonary embolectomy. A 63-year-old woman underwent emergency pulmonary embolectomy with cardiopulmonary bypass (CPB). During partial CPB, we found massive blood gushing out from the endotracheal tube. Approximately 2,000 ml of blood was aspirated in 10 minutes. To ensure adequate oxygenation, emergent percutaneous cardiopulmonary support system (PCPS) was started. After neutralization of heparin and the institution of 10 cmH2O of positive end-expiratory pressure, the bleeding diminished. Institution of PCPS allows performance of unhurried bronchoscopy to identify the actual bleeding point and to lavage the airway. In addition to this management, we administrated steroids and neutrophil elastase inhibitor to stabilize pulmonary capillary membrane. Without complications, the patient was extubated 2 days after operation and the following course was uneventful. Immediate institution of PEEP and pharmacological interventions to reduce pulmonary blood pressure were beneficial in arresting hemorrhage. The bleeding begins usually at the time of discontinuation of CPB. We should recognize the possible occurrence of endobronchial bleeding after pulmonary embolectomy and prepare to protect the airway and to maintain oxygenation and cardiac function.

    Intestinal obstruction is associated with significant morbidity and mortality. Scientific assessment of the cause, site of obstruction, appropriate correction of the fluid deficit and electrolyte imbalance with preoperative stabilization of blood gases is ideal as a preoperative workup. Placement of a preoperative epidural catheter especially in the thoracic interspace takes care of perioperative pain and stress reduction. Intraoperative management by controlled general anesthesia administering a relative high inspired fraction of oxygen with invasive monitoring in selected sick cases is mandatory. Preoperative monitoring and stabilizing raised intra-abdominal pressure reduces morbidity. Caution should be exercised during opening and closure of abdomen to avoid cardiorespiratory ill effects. There should be an emphasis on avoiding hypothermia. The use of nonsteroidal anti-inflammatory drugs may worsen sick, fragile patients. The use of sugammadex rather than neostigmine will obscure certain controversies in the healing of intestinal anastomotic site. Replacement of blood loss continued correction of fluids and electrolytes with possible postoperative mechanical ventilation in sick cases may improve outcomes in these patients. PMID:27746522

    Non-Fukuyama type congenital muscular dystrophy (n-FCMD), a subtype of progressive muscular dystrophy (PMD), is a very rare autosomal recessive disorder. N-FCMD is characterized by severe and progressive motor weakness and atrophies of proximal muscles during the infant period. A 9-year-old boy with n-FCMD underwent elective surgery for muscle release around the hip joints bilaterally. As many perioperative complications related with volatile anesthetics and muscle relaxants had been reported in the anesthetic management of PMD, these drugs were thought to be contraindicated in patients with n-FCMD. Because n-FCMD seemed to have very similar pathogenesis with PMD, caudal epidural block was chosen, supplemented with the administration of diazepam, pentazocine and nitrous oxide. The operation and anesthesia were conducted uneventfully. No complications occurred postoperatively.

    We report the successful management of anesthesia in a 46-year-old male dialysis patient with chronic inflammatory demyelinating polyneuropathy (CIDP). He underwent an osteosynthesis of the ankle joint using general anesthesia combined with epidural anesthesia. The anesthetic concerns in patients with CIDP are the possibility of postoperative respiratory dysfunction due to anesthetics or muscle relaxants and that of postoperative neurological deterioration due to spinal or epidural anesthesia. In this case, sevoflurane (1.5-2%) did not cause respiratory dysfunction postoperatively and muscle relaxant effect of rocuronium was effectively reversed by sugammadex. Epidural anesthesia using ropivacaine (0.2-0.375%) and fentanyl did not worsen the neurological symptoms of CIDP post-operatively.

    Objective:We are describing a novel technique to insert nasogastric tube (NGT) in the anesthetized patients dur-ing cervical esophageal reconstruction. Methods:Forty patients with mid and upper esophageal tumor enrol ed into this study were randomly al ocated into two groups (the control group, group C and the novel method group, group N). Al the patients were applied mechanical anastomosis to finish the cervical esophageal reconstruction. The procedure of NGT insertion for group C use the conventional method;wel , the group N use the novel technique. Results:Al the patients in group N had been finished the NGT insertion in the first attempt, and the total time for insertion was (5.05 ± 1.15) mins;on the contrary, for the group C, duration of insertion (min) was (24.45 ± 5.23) mins, and the successful rate of NGT insertion in the first attempt was 40%(P<0.05);no one in group N had coiling/kinking, and 6/20 (30%) in group C had it (P=0.020). The complication rate of bleeding between the two group had no significant dif erence. Conclusion:For the patient with mid and upper esophageal tumor who need cervical esophageal reconstruction, this novel method can save the NGT insertion time, and make it easier with higher successful rate.

    Stiff person syndrome is a rare neurologic disorder with an estimated incidence of 1:1000000. The underlying pathophysiology is truncal and proximal limb muscle stiffness resulting from continuous co-contracture of agonist and antagonist muscle groups concomitant with superimposed episodic muscle spasms. Loss of gamma-aminobutyric acid-mediated inhibition creates chronic excitation manifested by tonic agonist-antagonist muscle contraction. To date, only three case reports referred indirectly to the anesthetic management of parturients with Stiff person syndrome. The authors describe their management of a parturient with Stiff person syndrome who underwent urgent cesarean delivery under epidural anesthesia.

    ABSTRACT Objective: To compare the anesthetic techniques using propofol and fentanyl versus midazolam and remifentanil associated with a paracervical block with lidocaine in performing ultrasound-guided transvaginal oocyte aspiration. Methods: A randomized double-blind clinical trial (#RBR-8kqqxh) performed in 61 women submitted to assisted reproductive treatment. The patients were divided into two groups: anesthetic induction with 1mcg/kg of fentanyl associated with 1.5mg/kg of propofol (FP Group, n=32), in comparison with anesthetic induction using 0.075mg/kg of midazolam associated with 0.25mcg/kg/min of remifentanil, and paracervical block with 3mL of 2% lidocaine (MRPB Group, n=29). Main outcome measures: human reproduction outcomes, modified Aldrete-Kroulik index, hemodynamic parameters, and salivary cortisol. Results: The results revealed a higher number of embryos formed in the FP Group (p50=2 versus 1; p=0.025), gestation rate two times higher in the FP Group (44.4% versus 22.2%; p=0.127), less time to reach AK=10 in the MRPB Group (p50=10 versus 2; p<0.001), and lower mean of hemodynamic parameters in the MRPB Group (p<0.05). Conclusion: Anesthesia with fentanyl and propofol as well as with midazolam, remifentanil, and paracervical block offered satisfactory anesthetic conditions when performing assisted reproduction procedures, providing comfort for the patient and physician.

    The paper summarizes a 5-year experience of evaluating the safety of anesthetic management of patients with thermal lesions treated at the department of thermal lesions of Vishnevsky's Institute of Surgery, Russia's Academy of Medical Sciences. Regular internal auditings, based on the principles of registering the critical incidents, the course of 1473 general anesthesia managements was analyzed in 168 patients. The conclusion is that the introduction of protocols of anesthetic management as well as a regular monitoring over meeting the fixed targets cut the total frequency of critical incidents from 2.85 to 1.19 as estimated per one general anesthesia. Finally the authors suggest a concept whose essence in that the operation of the modern anesthesiology department must be based on a scientifically substantiated technology of anesthetic management.

    2014-04-01

    Full Text Available Situs inversus totalis is a congenital visceral malrotation anomaly that results from disturbances in establishment of left-right asymmetry and it is characterized by total transposition of thoracic and abdominal viscera, and the predicted incidence is one in 10, 000 among the general population. In a patient with situs inversus totalis, not just the diagnosis of any acute abdomen pathology is difficult but equally challenging is the anesthetic management during the respective surgical procedure. We are reporting a patient who had situs inversus totalis and was operated for laparoscopic cholecystectomy under general anesthesia with I-gel, a new supraglottic airway device as an airway conduit. Though the problems related to such patients are mainly of surgical feasibility, an anesthesiologist must be aware of the associated problems of both, situs inversus and the laparoscopy. The present case report lays an emphasis on the potential difficulties during anesthetic management and its various implications. To the best of our knowledge, we report the first case in India of a successful laparoscopic cholecystectomy in a patient with situs inversus totalis with use of I-gel.

    Two indirect blood pressure measurement techniques, Doppler (DOP) sphygmomanometry and oscillometry, applied at the ventral coccygeal artery were compared with simultaneous direct blood pressure measurements at the dorsal pedal artery in 10 anesthetized, captive cheetahs (Acinonyx jubatus). The DOP method was moderately accurate, with relatively little bias (mean difference 3.8 mmHg) and 88.6% of the DOP systolic arterial pressure measurements being within 10 mmHg of the direct systolic arterial measurement. With the oscillometric (OM) method, 89.2% of the mean arterial pressure measurements were within 10 mmHg of the direct measurement and had the least bias (mean difference 2.3 mmHg), 80.7% of the systolic measurements were within 10 mmHg of the direct measurement and had the second least bias (mean difference 2.3 mmHg), and 59% of the diastolic measurements were within 10 mmHg of the direct measurement and had significant bias (mean difference 7.3 mmHg). However, DOP showed relatively poor precision (SD 11.2 mmHg) compared with OM systolic (SD 8.0 mmHg), diastolic (SD 8.6 mmHg), and mean (SD 5.7 mmHg). Both techniques showed a linear relationship with the direct technique measurements over a wide range of blood pressures. The DOP method tended to underestimate systolic measurements below 160 mmHg and overestimate systolic measurements above 160 mmHg. The OM method tended to underestimate mean pressures below 160 mm Hg, overestimate mean pressures above 160 mmHg, underestimate systolic pressures below 170 mmHg, overestimate systolic pressures above 170 mmHg, and underestimate diastolic pressures throughout the measured blood pressure range. Indirect blood pressure measurement using the ventral coccygeal artery, particularly when using an OM device for mean and systolic arterial pressure, may be useful in the clinical assessment of cheetahs when monitoring trends over time, but caution should be taken when interpreting individual values.

    2012-01-01

    Full Text Available We describe the anesthetic management of a patient with severe myasthenia gravis and tracheal stenosis; the patient was scheduled for direct laryngoscopy and dilatation. The combination of myasthenia gravis and tracheal obstruction presents several difficulties for anesthetic management. The airway is shared; therefore, any complications are also shared by the anesthesiologist and bronchoscopists. The potential for respiratory compromise in patients undergoing the two procedures requires that anesthesiologists be familiar with the underlying disease state, as well as the interaction of anesthetic and nonanesthetic drugs in a case involving myasthenia gravis. We reviewed the literature and report our experience in this case. There is no strong evidence for choosing one approach to general anesthesia over another for bronchoscopy. Careful preoperative planning and experience in airway management and jet ventilation are crucial to prevent an adverse outcome and obtain favorable results.

    Ectodermal dysplasias are rare conditions with a triad of hypotrichosis, anodontia and anhidrosis. In literature review there have been only a few reports of anesthetic management of patients with ectodermal dysplasias. Hyperthermia is a very serious risk which may occur due to the defect of sweat glands. The present case involves a 10-year-old child with ectodermal dysplasia who presented with an acute abdomen and was considered for an emergency surgery. Our aim was to demonstrate the successful management of this case using a combination of general and epidural anesthesia. It is important for anesthesiologist to have information about this syndrome in case of emergency operations, since it can prevent serious complications and even save lives.

    Objective To investigate clinical features and anesthetic management of multiple endocrine neoplasia (MEN) associated with pheochromocytoma.Methods Medical records of patients who were diagnosed as multiple endocrine neoplasia a ssociated with pheochromocytoma in our hospital from April 1977 to April 2001 were reviewed retrospectively. The demographic data, clinical presentations, fami ly history, biochemical examinations, type of MEN, sequence of different surgica l procedures, anesthetic methods and hemodynamics during surgery were analyzed. Results Thirteen cases of MEN associated with pheochromocytoma were investigated, accounting for 6% (13/213) of the pheochromocytoma patients admitted into our hospital. Nine of the 13 patients presented as type Ⅱa MEN (Sipple syndrome), on e as type Ⅱb MEN, and three as mixed MEN. Four patients with typeⅡa MEN had a family history of similar disease. Five patients with other coexisting endocri ne disorders first underwent excision of the pheochromocytomas, although only tw o had hypertensive symptoms at the time of admittance. Seven patients without h istories of hypertension received surgical treatment for pheochromocytoma second ly. The excision of pheochromocytoma was performed under general anesthesia in 8 patients and epidural block in 4 patients. Marked hemodynamic fluctuation was recorded in 8 patients. No perioperative death was recorded. Conclusion Pheochromocytoma may be linked to other endocrine disorders during MEN, either as the main clinical presentation or most frequently as an occult tumor. Recognition of this feature of pheochromocytoma is of importance to the improvement of diagnosis and treatment both for pheochromocytoma and MEN.

    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.

    2010-01-01

    Full Text Available We describe the anesthetic management of a patient with hypertrophic obstructive cardiomyopathy with dual-chamber pacemaker undergoing transurethral resection of the prostate. Anesthetic challenges included prevention and management of perioperative arrhythmias, maintenance of adequate preload, afterload and heart rate to relieve left ventricular outflow tract obstruction and considerations related to the presence of dual-chamber pacemaker and TURP. We recommend preoperative reprogramming of the DDD pacemaker, avoidance of magnet application during the procedure, application of electrosurgical unit current returning pad to the anterior aspect of the thigh, especially if monopolar cautery is used, use of central venous pressure line for estimation of preload and careful titration of anesthetic drugs to maintain stable hemodynamics.

    Full Text Available Vallecular cyst is uncommon but well-recognized cause of upper airway obstruction in newborn and infants. We hereby present anesthetic management of a case of vallecular cyst in an infant posted for excision and marsupialization. A 4-month-old female infant weighing 3.5 kg presented with inspiratory stridor progressively worsening over 2 months. Anesthesia plan was to carry out inhalational induction maintaining spontaneous respiration and keeping tracheostomy as standby option. In this case, laryngoscopy was challenging due to the size and extent of the cyst thus necessitating gentle laryngoscopy to prevent cyst rupture and pulmonary aspiration. On performing laryngoscopy, epiglottis was not visualized, which made intubation difficult. At the end of surgery, extubation was not carried out as the possibility of laryngomalacia could not be eliminated and also in view of intraoperative airway manipulation. The patient was electively ventilated postoperatively and extubated on the 2 nd postoperative day.

    An ex utero intrapartum treatment (EXIT) procedure provides sufficient time to gain control of the potentially obstructed fetal upper airway while uterine placental circulation is maintained during cesarean section. We report 2 cases in which fetal congenital upper airway obstruction was managed without complications during EXIT procedures. We also discuss general considerations concerning the obstetric patient and the performance of intramuscular fetal anesthesia. Before the hysterotomy, sevoflurane at 1.5 minimum alveolar concentration was administered to assure sufficient uterine relaxation during EXIT. The 2 parturients remained hemodynamically stable during the procedure and uterine and placental perfusion was adequate. Nasotracheal intubation was possible in 1 fetus after a cervical mass was dissected. In the other, a tracheostomy was created. After the umbilical cord was clamped, the concentration of sevoflurane anesthetic gas was reduced and oxytocin and methylergometrine were administered to induce adequate uterine contractions within a few minutes. Both neonates survived the EXIT procedure with no complications.

    Full Text Available Anesthesia for emergency caesarean section for a pregnant patient with severe dorsolumbar kyphoscoliosis and severe anemia is associated with potential risks for both mother and the fetus due to alterations in maternal physiology and the pathological changes associated with kyphoscoliosis. In an emergency situation, the anesthesiologist has to quickly choose the anesthetic technique depending on the cardiopulmonary status of the patient and feasibility. We present a case of a 20 year old parturient in labour with severe kyphoscoliosis and severe anemia who was posted for emergency caesarean section. In view of severe anemia, anticipated technical difficulties with central neuraxial blocks and emergency situation, she was administered general anesthesia (GA with uneventful recovery.

    2012-11-01

    Tail biopsy in mice is a common procedure in genetically modified mouse colonies. We evaluated the anesthetic and analgesic effects of various agents commonly used to mitigate pain after tail biopsy. We used a hot-water immersion assay to evaluate the analgesic effects of isoflurane, ice-cold ethanol, ethyl chloride, buprenorphine, and 2-point local nerve blocks before studying their effects on mice receiving tail biopsies. Mice treated with ethyl chloride spray, isoflurane and buprenorphine, and 2-point local nerve blocks demonstrated increased tail-flick latency compared with that of untreated mice. When we evaluated the behavior of adult and preweanling mice after tail biopsy, untreated mice demonstrated behavioral changes immediately after tail biopsy that lasted 30 to 60 min before returning to normal. The use of isoflurane, isoflurane and buprenorphine, buprenorphine, 2-point nerve block, or ethyl chloride spray in adult mice did not significantly improve their behavioral response to tail biopsy. Similarly, the use of buprenorphine and ethyl chloride spray in preweanling mice did not improve their behavioral response to tail biopsy compared with that of the untreated group. However, immersion in bupivacaine for 30 s after tail biopsy decreased tail grooming behavior during the first 30 min after tail biopsy. The anesthetic and analgesic regimens tested provide little benefit in adult and preweanling mice. Given that tail biopsy results in pain that lasts 30 to 60 min, investigators should carefully consider the appropriate anesthetic or analgesic regimen to incorporate into tail-biopsy procedures for mice.

    To analyze the experience and anesthetic management in the transcatheter implantation of the CoreValve(®) self-expanding aortic valve, in a university tertiary hospital. Observational analytical review of data incorporated into a prospectively maintained database of 142 patients diagnosed with severe aortic stenosis who underwent implantation of a CoreValve(®) aortic self-expanding aortic valve between December 2007 and December 2012. The mean age of patients was 82.5±6.1 years and the logistic EuroSCORE was 14.9±11.2. General anesthesia was used in 107 patients (75.3%), with local anesthesia with sedation in 35 (24.6%). Local anesthesia and sedation was associated with a lower requirement of vasoactive drugs (P=.003) during implantation. No statistically significant differences were found between the 2 anesthetic techniques in the duration of the procedure, hospital stay, or morbimortality. The success rate was 97.1%. The most common complication was conduction disorders that required implantation of a permanent pacemaker in 46 patients (32.3%). There was no intraoperative mortality, and all-cause mortality at 30 days was 6.3%, with a one-year survival estimated by the Kaplan-Meier of 83.1%. This study confirms that in patients with severe aortic stenosis and high surgical risk, transcatheter implantation of aortic valve is a safe and effective alternative. Both, general anesthesia and local anesthesia with sedation are valid options, depending on the experience of the team.

    Hemophilia A is a hemorrhagic trend almost exclusively affecting males (X-related recessive disease). In 85% of cases, it is caused by factor VIII deficiency, called hemophilia A or classic hemophilia. Successful anesthetic management depends on the special care and a multidisciplinary team of health professionals informed about the disease, including qualified hematologist, surgeon, and anesthesiologist.

    Facial locoregional anesthetics (ALR) with nervous blocks are simple and reliable to perform, need little technical resources with a very low iatrogenic risk. These blocks allow anesthesia without deforming wound banks using the same materials as usual local anesthetic procedures. Three principal nervous blocks, in a straight line along the vertical pupil axis, allow managing - even extensive - facial wounds. Few side effects may occur which can be easily prevented. It is a good alternative to local anesthetic for the treatment of extensive and deep areas which is performed with a lower number of injections and a high rate of success. These techniques are easy to learn and practise. These anesthetic techniques allow a nice treatment of different kinds of facial wounds from simple suture to flaps.

    Chronic expanding hematoma (CEH) of the thorax is an intractable disease which induces long-standing growing hematoma after tuberculosis or thoracic surgery. It causes respiratory failure and heart failure by compressing the mediastinum. A 68-year-old man with a history of tuberculosis during childhood had suffered from progressive exertional dyspnea for 20 years. Because a huge hematoma occupying whole right thoracic cavity compressed the heart and the trachea to the left, he was scheduled for extrapleural pneumonectomy. Bronchial arterial embolization was performed preoperatively to prevent hemoptysis and reduce intraoperative blood loss. There was no problem in the airway management using a double lumen endotracheal tube. However, severe hypotension and a decrease in cardiac index were observed due to excessive bleeding, leading to total blood loss of 11,000 g. In addition, surgical manipulation caused abrupt severe hypotension. Monitoring of arterial pressure-based cardiac output and deep body temperature was useful for the hemodynamic management during the operation. The successful postoperative course resulted in remarkable improvement of Huge-Jones dyspnea criteria from IV to II. In the anesthetic management of CEH precautions should be taken against the excessive intraoperative bleeding and abrupt hemodynamic changes.

    MRI is becoming an indispensable diagnostic tool. The need for prolonged motion-free periods has substantially increased the need for deep sedation or anesthesia in a challenging environment. This review summarises recent literature with respect to pharmacological sedative strategies, nonpharmacological alternative approaches, airway management and safety issues in the ambulatory setting. Most literature researches the pediatric patient population. The American Society of Pediatrics published guidelines for monitoring and management of pediatric patients during sedation for diagnostic procedures. Dexmedetomidine is the most researched agent for sedation. It remains uncertain what the clinical implications are of the potential neurotoxicity of repeat sedation or anesthesia in young children. Airway strategies highlight the use of end-tidal carbon dioxide monitoring. Technical imaging advancement and nonpharmacological sedation alternatives allow for shorter procedures with a lower need for sedation. The anesthetic management of ambulatory patients in the MRI environment has its specific challenges and safety issues. However, the implementation of safety guidelines, new pharmacological and alternative nonpharmacological sedation strategies offer interesting perspectives to tackle these challenges.

    Full Text Available Subcostal transverse abdominis plane (TAP block anesthetizes area of the abdomen with cutaneous innervation of T6–T10 dermatomes. These abdominal field blocks become very advantageous when cardiac patient presents for noncardiac surgeries as sole anesthetic or as a part of multimodal anesthesia. A 58-year-male came for open surgical repair of subxiphoid incisional hernia developed post coronary artery bypass grafting (CABG. Echocardiography showed hypokinesia of left ventricle (LV in the left anterior descending (LAD artery territory, dilated LV, and ejection fraction of 30%, and coronary angiography after 6 months of CABG showed 70% stenosis of LAD. Surgery was successfully accomplished under ultrasound-guided bilateral subcostal TAP block except for a brief period of pain and discomfort when hernia was being reduced which required narcotic supplementation. The patient remained comfortable throughout the procedure as well as 24 h postoperatively without any analgesic supplementation. Thus, subcostal TAP block can be a safe alternative to neuraxial or general anesthesia for epigastric hernia repair in selected patients.

    Full Text Available BACKGROUND AND OBJECTIVES: Goldenhar's syndrome is a polymalformative condition consisting of a craniofacial dysostosis that determines difficult airway in up to 40% of cases. We described a case of a newborn with Goldenhar's syndrome with esophageal atresia and tracheoesophageal fistula who underwent repair surgery.CASE REPORT: We report the case of a 24-h-old newborn with Goldenhar's syndrome. He had esophageal atresia with distal tracheoesophageal fistula. It was decided that an emergency surgery would be performed for repairing it. It was carried out under sedation, intubation with fibrobronchoscope distal to the fistula, to limit the air flow into the esophagus, and possible abdominal distension. Following complete repair of the esophageal atresia and fistula ligation, the patient was transferred to the intensive care unit and intubated under sedation and analgesia.CONCLUSIONS: The finding of a patient with Goldenhar's syndrome and esophageal atresia assumes an exceptional situation and a challenge for anesthesiologists, since the anesthetic management depends on the patient comorbidity, the type of tracheoesophageal fistula, the usual hospital practice and the skills of the anesthesiologist in charge, with the main peculiarity being maintenance of adequate pulmonary ventilation in the presence of a communication between the airway and the esophagus. Intubation with fibrobronchoscope distal to the fistula deals with the management of a probably difficult airway and limits the passage of air to the esophagus through the fistula.

    Full Text Available Abstract Background We made a survey among Finnish anesthesiologists concerning the current perioperative anesthetic practice of hip fracture patients for further development in patient care. Methods All members of the Finnish Society of Anesthesiologists with a known e-mail address (786 were invited to participate in an internet-based survey. Results The overall response rate was 55% (423 responses; 298 respondents participated in the care of hip fracture patients. Preoperative analgesia was mostly managed with oxycodone and paracetamol; every fifth respondent applied an epidural infusion. Most respondents (98% employed a spinal block with or without an epidural catheter for intraoperative anesthesia. Midazolam, propofol and/or fentanyl were used for additional sedation. General anesthesia was used rarely. Postoperatively, paracetamol and non-steroidal anti-inflammatory drugs and occasionally peroral oxycodone, were prescribed in addition to epidural analgesia. Conclusions The survey suggests that the impact of more individualised analgesia regimens, both preoperatively and postoperatively, should be investigated in further studies.

    Full Text Available Objective To explore the anesthetic management strategy in children undergoing adenoidectomy and tonsillectomy using low-temperature plasma technology. Methods Sixty ASA status I children scheduled for adenoidectomy and tonsillectomy with plasma technology in the First Affiliated Hospital of General Hospital of PLA from September to December of 2013 were enrolled in this study. After induction with propofol, sufentanil and cisatracurium, the children were randomly divided into combined inhalation and intravenous anesthesia group (CIIA group, n=30 and total intravenous anesthesia group (TIVA group, n=30. In CIIA group, anesthesia was maintained with continuous infusion of propofol and remifentanil combined with sevoflurane inhalation during the surgery. In TIVA group, anesthesia was maintained only with continuous infusion of propofol and remifentanil. The hemodynamic changes and time for extubation and leaving operating room were recorded, and the emergence agitation was assessed using Pediatric Anesthesia Emergence Delirium (PAED scale. Results There was no significant difference in hemodynamic changes between the two groups (P>0.05. The total dosages of propofol and remifentanil in TIVA group [10.5±3.4 mg/(kg.h and 16.1±5.3μg/(kg.h, respectively] were significantly higher than those of CIIA group [6.6±2.8 mg/(kg.h, 10.4±4.2 μg/(kg.h, P<0.05]. The times for extubation and leaving operating room were significantly shorter in TIVA group (8.8±3.7min, 6.2±2.9min than in CIIA group (19.8±4.3 min, 13.7±5.2 min, P<0.05, and the rate of emergence agitation during the recovery period in TIVA group (1/30 was significantly less than that in CIIA group (9/30, P<0.05. Conclusion  Total intravenous anesthesia with tracheal intubation could shorten the recovery time and lessen the emergence agitation during the recovery period, and it may be used as a safe, feasible and convenient anesthetic strategy for adenoidectomy and tonsillectomy with

    Full Text Available OBJECTIVE: The standard therapy for patients with high-level spinal cord injury is long-term mechanical ventilation through a tracheostomy. However, in some cases, this approach results in death or disability. The aim of this study is to highlight the anesthetics and perioperative aspects of patients undergoing insertion of a diaphragmatic pacemaker. METHODS: Five patients with quadriplegia following high cervical traumatic spinal cord injury and ventilator-dependent chronic respiratory failure were implanted with a laparoscopic diaphragmatic pacemaker after preoperative assessments of their phrenic nerve function and diaphragm contractility through transcutaneous nerve stimulation. ClinicalTrials.gov: NCT01385384. RESULTS: The diaphragmatic pacemaker placement was successful in all of the patients. Two patients presented with capnothorax during the perioperative period, which resolved without consequences. After six months, three patients achieved continuous use of the diaphragm pacing system, and one patient could be removed from mechanical ventilation for more than 4 hours per day. CONCLUSIONS: The implantation of a diaphragmatic phrenic system is a new and safe technique with potential to improve the quality of life of patients who are dependent on mechanical ventilation because of spinal cord injuries. Appropriate indication and adequate perioperative care are fundamental to achieving better results.

    Full Text Available Osteogenesis imperfecta is a rare disorder of connective tissues and presents multiple challenges, including difficult airway, hyperthermia, coagulopathy and respiratory dysfunction, for anesthesiologists, especially during cardiac surgery. We present anesthetic management of a patient with osteogenesis impertecta during double valve surgery. Dexmedetomidine infusion minimized the risks of malignant hyperthermia. Glidescope and in-line stabilization facilitated endotracheal intubation and protected his oral structures and cervical spine. Transesophageal echocardiography (TEE diagnosed a flail A3 segment and redundant left coronary cusp causing mitral and aortic regurgitation. The mitral valve was replaced and the aortic valve repaired. Coagulopathy was corrected according to comprehensive coagulation analysis. Glidescope, dexmedetomidine, coagulation analysis and TEE could facilitate anesthetic management in these patients.

    As of mid-October 2014, the ongoing Ebola epidemic in Western Africa has affected approximately 10,000 patients, approached a 50% mortality rate, and crossed political and geographic borders without precedent. The disease has spread throughout Liberia, Guinea, and Sierra Leone. Isolated cases have arrived in urban centers in Europe and North America. The exponential growth, currently unabated, highlights the urgent need for effective and immediate management protocols for the various health care subspecialties that may care for Ebola virus disease patients. We conducted a comprehensive review of the literature to identify key areas of anesthetic care affected by this disease. The serious potential for "high-risk exposure" and "direct contact" (as defined by the Centers for Disease Control and Prevention) of anesthesiologists caring for Ebola patients prompted this urgent investigation. A search was conducted using MEDLINE/PubMed, MeSH, Cochrane Review, and Google Scholar. Key words included "anesthesia" and/or "ebola" combined with "surgery," "intubation," "laryngoscopy," "bronchoscopy," "stethoscope," "ventilation," "ventilator," "phlebotomy," "venous cannulation," "operating room," "personal protection," "equipment," "aerosol," "respiratory failure," or "needle stick." No language or date limits were applied. We also included secondary-source data from government organizations and scientific societies such as the Centers for Disease Control and Prevention, World Health Organization, American Society of Anesthesiologists, and American College of Surgeons. Articles were reviewed for primary-source data related to inpatient management of Ebola cases as well as evidence-based management guidelines and protocols for the care of Ebola patients in the operative room, infection control, and health care worker personal protection. Two hundred thirty-six articles were identified using the aforementioned terminology in the scientific database search engines. Twenty articles

    As the American healthcare system continues to evolve and reimbursement becomes tied to value-based incentive programs, perioperative pain management will become increasingly important. Regional anesthetic techniques are only one component of a successful multimodal pain regimen. In recent years, the use of peripheral and paraneuraxial blocks to provide chest wall and abdominal analgesia has gained popularity. When used within a multimodal regimen, truncal blocks may provide similar analgesia when compared with other regional anesthetic techniques. While there are other reviews that cover this topic, our review will also highlight the emerging role for serratus plane blocks, pectoral nerve blocks and quadratus lumborum blocks in providing thoracic and abdominal analgesia.

    Objective: To assess the effects of various anesthetic techniques and PaCO2 levels on cerebral oxygen supply/consumption balance during craniotomy for removal of tumors, and to explore an anesthetic technique for neurosurgery and an appropriate degree of PaCO2 during neuroanesthesia. Methods: One hundred and fourteen patients with supratentorial tumors for elective craniotomy, ASA grade Ⅰ-Ⅱ, were randomly allocated to six groups. Patients were anesthetized with continuous intravenous infusion of 2% procaine 1.0 mg*kg-1*min-1 in Group Ⅰ, inhalation of 1.0%-1.5% isoflurane in Group Ⅱ, and infusion of 2% procaine 0.5 mg*kg-1*min-1 combined with inhalation of 0.5%-0.7% isoflurane in Group Ⅲ during the period of study. The end-tidal pressure of CO2 (PET CO2 )was maintained at 4.0 kPa in these 3 groups. In Group Ⅳ, Ⅴ and Ⅵ, the anesthetic technique was the same as that in Group Ⅰ but the PETCO2 was adjusted to 3.5, 4.0 and 4.5 kPa respectively for 60 min during which the study was performed. The radial arterial and retrograde jugular venous blood samples were obtained at the onset and the end of this study for determining jugular venous bulb oxygen saturation (SjvO2), arteriovenous oxygen content difference (AVDO2) and cerebral extraction of oxygen (CEO2). Results: In Group Ⅰ and Ⅲ SjvO2, AVDO2 and CEO2 remained stable. Although SjvO2 kept constant, AVDO2 and CEO2 decreased significantly (P<0.05) in Group Ⅱ. Moreover, AVDO2 and CEO2 in Group Ⅱ were significantly lower than those of Group Ⅲ (P<0.05). In Group Ⅳ, 60 min after hyperventilation, SjvO2 and jugular venous oxygen content(CjvO2) decreased markedly (P<0.01) while CEO2 increased significantly (P<0.01). In addition, SjvO2, CjvO2 and CEO2 in Group Ⅳ were significantly different from the corresponding parameters in Group Ⅴ and Group Ⅵ (P<0.05). In view of sustained excessive hyperventilation, SjvO2 was less than 50% in 37.5% patients of Group Ⅳ. Conclusion: Anesthesia with

    To compare the anesthetic techniques using propofol and fentanyl versus midazolam and remifentanil associated with a paracervical block with lidocaine in performing ultrasound-guided transvaginal oocyte aspiration. A randomized double-blind clinical trial (#RBR-8kqqxh) performed in 61 women submitted to assisted reproductive treatment. The patients were divided into two groups: anesthetic induction with 1mcg/kg of fentanyl associated with 1.5mg/kg of propofol (FP Group, n=32), in comparison with anesthetic induction using 0.075mg/kg of midazolam associated with 0.25mcg/kg/min of remifentanil, and paracervical block with 3mL of 2% lidocaine (MRPB Group, n=29). Main outcome measures: human reproduction outcomes, modified Aldrete-Kroulik index, hemodynamic parameters, and salivary cortisol. The results revealed a higher number of embryos formed in the FP Group (p50=2 versus 1; p=0.025), gestation rate two times higher in the FP Group (44.4% versus 22.2%; p=0.127), less time to reach AK=10 in the MRPB Group (p50=10 versus 2; panestesia com 1mcg/kg de fentanil associada com 1,5mg/kg de propofol (Grupo FP, n=32), em comparação com ao grupo submetido à indução da anestesia utilizando 0,075mg/kg de midazolam associada com 0,25mcg/kg/min de remifentanil, e bloqueio paracervical com 3mL de lidocaína a 2% (Grupo MRBP, n=29). Foram avaliados os resultados reprodutivos, índice modificado de Aldrete e Kroulik, parâmetros hemodinâmicos e cortisol salivar. Foi encontrado um número mais elevado de embriões formados no Grupo FP (p50=2 versus 1; p=0,025), taxa de gestação duas vezes mais elevada no Grupo FP (44,4% versus 22,2%; p=0,127), menos tempo para alcançar AK=10 no Grupo MRBP (p50=10 versus 2; panestesias (com fentanil e propofol, e com midazolam, remifentanil e bloqueio paracervical) ofereceram condições anestésicas satisfatórias na realização de procedimentos realizados em reprodução assistida, proporcionando conforto para o paciente e médico.

    Charcot-Marie-Tooth disease (CMTD) is a hereditary peripheral neuropathy and is characterized by progressive muscle atrophy and motor-sensory disorders in all 4 limbs. Most reports have indicated that major challenges with general anesthetic administration in CMTD patients are the appropriate use of nondepolarizing muscle relaxants and preparation for malignant hyperthermia in neuromuscular disease. Moderate sedation may be associated with the same complications as those of general anesthesia, as well as dysfunction of the autonomic nervous system, reduced perioperative respiratory function, difficulty in positioning, and sensitivity to intravenous anesthetic agents. We decided to use intravenous sedation in a CMTD patient and administered midazolam initially and propofol continuously, with total doses of 1.5 mg and 300 mg, respectively. Anesthesia was completed in 3 hours and 30 minutes without adverse events. We suggest that dental anesthetic treatment with propofol and midazolam may be effective for patients with CMTD.

    Patients with prosthetic heart valves are a challenge to any anesthesiologist due to the risk of infective endocarditis, bleeding and thrombosis. We present anesthetic management of a 58-year-old Indian lady with a prosthetic (mechanical) heart valve who underwent hemireplacement arthroplasty. Patients with prosthetic heart valves, especially those with the mechanical valves are prone for thrombosis and resultant complications if anticoagulation is not maintained properly. However, when they are scheduled for major surgery, they can be best managed by normalising the coagulation profile immediately prior to surgery and restarting the anticoagulation as early as possible.

    Glutaric aciduria type 1 (GA1) is a rare, inherited mitochondrial disorder that results from deficiency of mitochondrial glutaryl-CoA dehydrogenase. Most patients develop neurological dysfunction early in life, which leads to severe disabilities. We present a 37-month-old girl with GA1 manifested as macrocephaly and hypotonia who received comprehensive dental restoration surgery under general anesthesia with sevoflurane. She was placed on specialized fluid management during a preoperative fasting period and anesthesia was administered without complications. All the physiological parameters, including glucose and lactate blood levels and arterial blood gas were carefully monitored and maintained within normal range perioperatively. Strategies for anesthetic management should include prevention of pulmonary aspiration, dehydration, hyperthermia and catabolic state, adequate analgesia to minimize surgical stress, and avoidance of prolonged neuromuscular blockade. We administered general anesthesia with sevoflurane uneventfully, which was well tolerated by our patient with GA1. Additionally, communication with a pediatric geneticist and surgeons should be undertaken to formulate a comprehensive anesthetic strategy in these patients.

    We consider that general anesthesia will be an appropriate and safe method as regional methods could lead to significant time loss in the prevention or minimization of complications. High blockage required for regional anesthetic methods in pregnant women with TGA and the maintenance of hemodynamic stability may become difficult due to neuroaxial sympathectomy even if a successful neuroaxial block has been provided. Agents with minimal effect on cardiovascular functions should be preferred for anesthesia induction and maintenance and close hemodynamic monitoring should be done during intraoperative and postoperative periods.

    Full Text Available Endocrine surgeries have been on the rise for the last few years. During surgery, endocrine disorders present unique challenges to the endocrinologist and to the attending anesthesiologist. The endocrine, electrolyte and metabolic disturbances resulting from such disorders can have a profound effect on the normal human physiological milieu. Surgery of parathyroid glands is no exception and is associated with a multiple challenges during pre-, intra-, and post-operative period. Pre-op examination and optimization is essential so as to prevent any intra-op or post-op complications. The most striking electrolyte disturbance during parathyroid surgery is the imbalance of calcium levels in the body and the main emphasis during the entire peri-operative period revolves around the maintenance of normal serum calcium levels. The present article review in depth the various anesthetic considerations and implications during parathyroid surgery with an emphasis on pre-op preparation for elective and emergency surgery.

    Guillain-Barré syndrome is an acute inflammatory demyelinating polyradiculopathy characterized by progressive motor weakness, areflexia, and ascending paralysis. Guillain-Barré syndrome is extremely rare in pregnant patients, and there are no established guidelines for delivery or safest anesthetic methods. We report a Cesarean delivery in the case of a 32-year old woman who was diagnosed with Guillain-Barré syndrome 18 weeks into gestation. Tracheostomy was performed due to progressive respiratory muscle weakness and respiratory failure, and ventilator support was required in the intensive care unit. The respiratory difficulty was exacerbated by the growth of the fetus, necessitating emergency Cesarean delivery. The delivery was successfully performed under general anesthesia, and the patient recovered without neurological sequelae.

    Since the introduction of cocaine local analgesia in 1886, and the subsequent development of procaine (1904) and other closely related ester-type compounds, dentistry has prided itself on being as close to 'painless' as possible. In the late 1940s the newest group of the local anesthetic compounds, the amides, was introduced. The initial amide local analgesic, lignocaine (Xylocaine), revolutionised pain control in dentistry worldwide. In succeeding years other amide-type local anesthetics, mepivacaine, prilocaine, bupivacaine and etidocaine, were introduced. They gave the dental practitioner a local anesthetic armamentarium which provided pulpal analgesia for periods of from 20 minutes (mepivacaine) to as long as three hours (bupivacaine and etidocaine with adrenaline). In addition these popular drugs proved to be more rapid-acting than the older ester-type drug and, at least from the perspective of allergenicity, more safe. In 1976, in Germany, the newest amide local analgesic, carticaine HCl was introduced into dentistry. Articaine (the generic name was changed) possesses properties similar to lignocaine but has additional properties which made the drug quite attractive to the general dental practitioner. In 1986 articaine was introduced in North America (Canada) where it has become the most used local anesthetic, supplanting lignocaine. Articaine has been approved for use in the United Kingdom. In this introductory discussion we review the development of articaine and discuss its place in the dental local analgesic armamentarium.

    In a deregulated/reformed environment, the electric utilities are under constant pressure for reducing operating costs, enhancing the reliability of transmission and distribution equipments, and improving quality of power and services to the customer. Moreover, the risk involved in running the system without proper attention to assets integrity in service is quite high. Additionally, the probability of losing any equipment vital to the transmission and distribution system, such as power and distribution transformers, is increasing especially with the aging of power system's assets. Today the focus of operating the power system is changed and efforts are being directed to explore new approaches/techniques of monitoring, diagnosis, condition evaluation, maintenance, life assessment, and possibility of extending the life of existing assets. In this paper, a comprehensive illustration of the transformer asset management activities is presented. The importance of each activity together with the latest researches done in the area is highlighted. (author)

    2013-01-01

    Full Text Available A 57-year-old man presented with chest pain and shortness of breath 1 month after left ventricular aneurysmectomy and ventricular septal defect closure for post-infarct left ventricular aneurysm and ventricular septal defect. Echocardiography revealed a large recurrent ruptured inferior left ventricular aneurysm with high-velocity flow into a 5 cm posterolateral pericardial effusion. Thirty minutes earlier, the patient had eaten a full meal. Rapid sequence induction was performed with midazolam, ketamine, and succinylcholine. Moderate hypotension was treated effectively and the patient tolerated controlled transition to cardiopulmonary bypass. The ventricular defect was oversewn and reinforced with bovine pericardium. The patient had a difficult but ultimately successful recovery. Options for anesthetic management in the setting of tamponade and a full stomach are discussed, with a brief review of the evidence relating to this clinical problem.

    Full Text Available Bleeding is a common problem during resection of a retroperitoneal mass. Massive bleeding may occur in case of injury of an adjacent major vessel or organ. This case report describes a successful anesthetic management of a patient with 10 l of blood loss within three hours surgery. A 44-year-old woman who underwent an operation for resection of a retroperitoneal mass, went to a hypovolemic shock, due to acute life-threatening intra-operative bleeding, and was successfully rescued with a combination of measures, including control of surgical bleeding, supportive treatment with rapid fluid infusion, massive transfusion of blood products and administration of intravenous vasoactive agents for maintaining tissue perfusion and oxygenation, utilizing intraoperative autologous blood salvaged via cell saver, as well as prevention and treatment of complications. The patient received a total of 22 units of Packet Red Blood Cells (PRBCs, 18 units of Fresh Frozen Plasma (FFP, 10 units of cryoprecipitate, 3750 ml of her own salvage blood. Postoperatively, she was transferred to the intensive care unit (ICU with mechanical ventilator support, where she received another 5.4 units of FFP, 10 units of cryoprecipitate. The patient developed features of early acute lung injury such as fever and hypoxemia, and was managed successfully with mechanical ventilator support for a few days. At a three-month follow-up, the patient was doing very well. This paper explores the pathogenesia, implications, prevention and treatment of the transfusion-associated complications such as acidosis, hypothermia, electrolyte abnormalities, and transfusion-related acute lung injury (TRALI. Particular attention is given to the prevention of secondary coagulopathy of the patient requiring massive blood transfusion. This case study presents a good reference for similar anesthetic scenario in the future.

    Full Text Available Ebstein′s anomaly (EA is the most common cause of congenital tricuspid regurgitation. The associated anomalies commonly seen are atrial septal defect or patent foramen ovale and accessory conduction pathways. Its association with coexisting mitral stenosis (MS has uncommonly been described. The hemodynamic consequences and anesthetic implications, of a combination of EA and rheumatic MS, have not so far been discussed in the literature. We report successful anesthetic management of a repair of EA and mitral valve replacement in a patient with coexisting Wolff-Parkinson-White (WPW syndrome.

    Stiff-person syndrome is an uncommon disease characterized by muscular rigidity and painful spasms in the axial and limb muscles. We report a 58-year-old woman with stiff-person syndrome undergoing thymectomy under general anesthesia. Before surgery, her medications were 25 mg of diazepam, 2 mg of clonazepam, and 15 mg of gabapentin per day. After epidural catheterization for the postoperative analgesia, general anesthesia was induced and maintained with continuous remifentanil infusion and propofol with target controlled infusion. With train-of-four ratio (TOFR) monitoring by stimulating the ulnar nerve, her trachea was intubated after 0.6mg x kg(-1) of rocuronium intravenous administration. Since then, additional rocuronium was not given for 4 hours. After surgery, she was fully awake and TOFR recovered to 100%, but tidal volume was too low to remove the tracheal tube, and mechanical ventilation was continued in ICU. On the next day, the tracheal tube was removed, and she was discharged from ICU. Because anesthetics may delay the recovery of respiratory function in a patient with stiff-person syndrome, careful assessment of respiratory function is needed at the emergence from general anesthesia.

    Full Text Available : Salinization of Ghanaian soils is on the rise. Organic matter application has not proved an effective and feasible technique for curbing this rise. Hence this paper seeks to review techniques that Ghana is using to manage its saline soils and further recommend a feasible, cost effective and beneficial technique for exhaustive research and possible adoption in the future. Halophytes appear to be the most feasible, cost effective and beneficial technique which could be adopted for the effective management of Ghanaian saline soils. But where halophytes are exotic, care must be taken to avoid competition with native species and allow preservation of agrobiodiversity

    Full Text Available Broncho-esophageal fistula (BEF are quite rare in adults, more so the congenital variety. The common causes of BEF in adults include infections, trauma, and malignancies. We report a rare case of congenital BEF manifesting in adulthood with repeated pulmonary infections. We emphasize mainly on the preoperative preparation and perioperative management of this patient. It is essential to have a high index of suspicion to diagnose congenital BEF in adults. Anesthesiologists play an important role in successful management of these cases.

    offers many advantages for high−risk patients, but the difficulties of these procedures do not only depend on the surgical technique, but on the anesthetic management, which is a challenge for the cardiovascular anesthesiologist. The objective of this research was to demonstrate the feasibility of the anesthetic management for video−assisted surgical techniques designed at Cardiocentro CIMEQ, and to compare the behavior of some variables in two study groups. Method: A retrospective study of patients who underwent heart surgery in the past three years at Cardiocentro CIMEQ. They were divided into two groups according to the surgical technique used. Patients operated using conventional cardiac surgery (median sternotomy were included in group 1, and those with minimally invasive cardiac surgery were included in group 2, to whom an anesthetic technique designed for this purpose was used. Results: The anesthetic, surgical, extracorporeal circulation and aortic clamping time and the number of units of transfused red blood cells per patient was significantly lower in the video−assisted cardiac surgery group. The stay in the Intensive Care Unit and in the cardiology department was similar, and so was the onset of walking and postoperative complications. Conclusions: The anesthesia management with this work protocol is safe and feasible. Patients operated with this technique have a very good recovery, few postoperative complications, and shorter hospital stays. In addition, it is a good choice for high−risk patients in need of surgery, which do not meet the criteria for percutaneous treatment.

    Meckel-Gruber syndrome, characterized by occipital encephalocele, microcephaly, polydactyly, cleft lip or palate, mandibular micrognathism, and anatomical abnormality of the larynx and tongue, along with other associated malformations, is in the list of diseases associated with difficult airway. However, there has been no report on the management of general anesthesia and airway management for such patients. A 2-year-old girl with Meckel-Gruber syndrome was scheduled for cardioplasty and gastrostomy for gastroesophageal reflux under general anesthesia. Preoperative examination revealed obesity, microgenia, dysspondylism, proteinuria, hypoplastic kidneys, and stenosis of the anal canal. Although we anticipated some difficulty with the intubation and prepared several alternative methods for intubation, such as a bronchofiberscope and a laryngeal mask airway, tracheal intubation was completed without difficulty using conventional laryngoscopy after inhalational induction with sevoflurane. Because most patients with this syndrome die before and shortly after delivery, those who survive to some age might have less severe deformities.

    Pediatric hypertensive crisis is a potentially life threatening medical emergency, usually secondary to an underlying disease. Hypertension commonly occurs during general anesthesia, and is usually promptly and appropriately treated by anesthesiologists. However in children with severe, unexplained, or refractory hypertension, it has the potential to cause morbidity and even mortality in susceptible patients. We report an anesthetic management of an unexpected hypertensive crisis that developed during general anesthesia in a three-year-old girl with undiagnosed severe left renal artery stenosis.

    2013-06-01

    Over the last decade, TECAB has matured into a reproducible technique associated with low incidence of both mortality and morbidity, as well as superior quality of life, when compared with open CABG surgery. However, TECAB also is associated with important and specific challenges for the anesthesiology team, particularly with regard to the physiologic stresses of OLV, placement of special catheters, and induced capnothorax. As the technology supporting robotic surgery evolves and familiarity with, and confidence in, TECAB increases, the authors anticipate increasingly widespread use of these procedures in an increasingly fragile and problematic patient population who will require the support of a skilled and vigilant anesthesiology team.

    2010-01-01

    Full Text Available The relationship between myasthenia gravis (MG and other autoimmune disorders like hyperthyroidism is well known. It may manifest earlier, concurrently orafter the appearance of MG. The effect of treatment of hyperthyroidism on the control of MG is variable. There may be resolution or conversely, deterioration of the symptoms also. We present a patient who was diagnosed to be hyperthyroid two and half years before the appearance of myasthenic symptoms. Pharmacotherapy for three months neither improved the myasthenic symptoms nor the thyroid function tests. Thymectomy resulted in control of MG as well as hyperthyroidism. In conclusion, effective control of hyperthyroidism in the presence of MG may be difficult. The authors opine that careful peri-operative management of thymectomy is possible in a hyperthyroid state.

We present the successful management of a palladial deep brain stimulator (DBS implantation for Meige′s syndrome. Dexmedetomidine infusion was used for sedation. The procedure lasted for around 12 h and the patient was comfortable, responsive, and cooperative over the extended period of time. The surgeons were comfortable with electrophysiologic brain mapping and clinical testing. DBS were implanted, through a burr hole, into the globus pallidus neurophysiological testing under guidance. The pulse generator battery was subcutaneously implanted into the chest wall under general anesthesia. The implanted pulse generator battery was started 2 days later and the patient showed dramatic improvement in his symptoms.

    Full Text Available Double outlet right ventricle (DORV is a rare congenital heart defect involving the great arteries. In DORV, both aorta and pulmonary artery arise from the right ventricle resulting in admixture of blood. We report a 22-year-old parturient with DORV and severe pulmonary stenosis who underwent caesarean delivery at 36 weeks gestation with low dose combined spinal-epidural anesthesia. This lady was assessed by echocardiogram to have situs inversus, dextrocardia, severe pulmonary artery stenosis (gradient = 146 mm Hg, DORV with subarterial VSD (1 cm. She had 95% room air saturation and her blood investigations were within normal limits. We established a peripheral venous access and radial arterial line for continuous blood pressure monitoring. Combined spinal epidural anesthesia was considered a better option. Epidural catheter was secured at L 2 -L 3 space and fixed after giving test dose 3 mL 2% lignocaine. Subarachnoid block administered at L 3 -L 4 level using 1.2 mL of 0.5% heavy bupivacaine. A sensory block of T 10 was obtained which was supplemented with 4 mL 0.75% ropivacaine to obtain a level of T 6 . Patient tolerated the procedure well. She was shifted to post-operative ICU. Post-operative pain was managed with epidural 0.2% ropivacaine at 4 mL/h. Patient remained hemodynamically stable throughout the procedure and in the postoperative period while she was being followed up for subsequent 48 h.

    We administered general anesthesia for a patient with 8 trisomy mosaic and cerebral palsy. Constitutional 8 trisomy mosaic has been associated with syndromic dysmorphology, corneal opacities, leukemia and trophoblastic disease. In Japan only 4 reports of general anesthesia related with 8 trisomy were found. This patient was a 24-year-old woman (140 cm, 35 kg), with mental retardation, poor body development and severe scoliosis. Since she suffered from repeated serious asthma and pneumonia since childhood, tracheotomy was performed at the age of 9. Epileptic seizures were also seen and antiepileptics were prescribed. This time, general anesthesia was scheduled for the extraction of a maxillary cyst. Anesthesia was induced slowly with sevoflurane from the tracheotomy, followed by rocuronium 25 mg i.v., and maintained with sevoflurane 1.5-2 % and remifentanil 0.05-0.2 microg x kg(-1) x min(-1) Throughout the operation, BIS score fluctuated between 40-60, and stable anesthesia was maintained. We reversed the rocuronium with sugammadex 140 mg promptly. The 8 trisomy mosaic patient is known to have various complications related to circulation and respiration. Careful management is necessary in anesthesia for an 8 trisomy patient.

    Full Text Available Maternal connective tissue disorders such as Systemic Lupus Erythematosus (most common, Sjogren′s syndrome, mixed connective tissue disorders may lead to the rare condition of complete congenital heart block in the neonate. Rare fetal syndromes such as myocarditis, 18p syndrome, mucopolysaccharidoses and mitochondrial diseases are other causes. The mortality rate of this condition is inversely propotional to the age of presentation being 6 % in the neonatal age group. As the cardiac output in the neonate is heart rate dependent, it is crucial to maintain the heart rate in these patients. Pharamacological interventions with dopamine, isoprenaline, epinephrine and atropine are known for their variable response. Although permanent pacing is the most reliable mode of management, the access to it is often not readily available, especially in the developing countries. In such cases temporary pacing methods become lifesaving. Of all the modalities of temporary pacing (transcutaneous, transesophageal and transvenous transcutaneous pacing is the most readily available and immediate mode. In this case report we present a two day old neonate with isolated complete congenital heart block and a resting heart rate of 50-55/min in immediate need of palliative surgery for trachea-esophageal fistula (TEF. With pharmacological intervention the heart rate could only be raised to 75-80/min. The surgery was successfully carried out using transcutaneous pacing to maintain a heart rate of 100/min.

    Rett syndrome (RTT) is a congenital neurological disorder associated with mutations in the gene encoding MECP2 on the X chromosome. An 18-year-old woman (150 cm in height and 29 kg in weight) had been diagnosed with RTT and showed myotonic trismus, frequent attacks of apnea, mental retardation, spastic paraplegia, scoliosis, and microcephalus with micrognathia. She was scheduled to undergo laparoscopic fundoplication and gastrostomy under general anesthesia. Nasal bronchofiberscopic intubation (BFI) was planned because difficult airway due to trismus and micrognathia was expected. Referring to the bispectral index (BIS), anesthesia was induced with intermittent intravenous thiopental (total 125 mg), resulting in successful opening of the mouth by 1.5 of a finger width and establishment of manual ventilation. Following intravenous administration of rocuronium (20 mg), oral BFI was easily accomplished despite Cormack grade III. Anesthesia was satisfactorily maintained with inhalation of sevoflurane (1.0-1.5%) and continuous infusion of remifentanil (0.1-0.2 microg x kg(-1) x min(-1)) with the BIS value ranging from 30 to 50. She recovered smoothly from anesthesia using sugammadex (50 mg). However, she immediately demonstrated trismus and an attack of apnea with shivering, which were successfully resolved by warming the body and intravenous fentanyl (50 microg bolus and subsequent infusion at a rate of 10 microg x hr(-1)). The postoperative course was uneventful. Characteristically, RTT shows an extremely wide range of neurological symptoms. Therefore, it is of great importance to respond to each of those symptoms during the perioperative management of patients with RTT.

In this prospective study, 30 uncooperative patients with MR receiving total intravenous anesthesia (TIVA) with propofol for APBMCT were randomized into 3 groups with monitored anesthesia care (MAC group), inserted classic laryngeal mask airway under general anesthesia (LMA group), or endotracheal tube placement (ETT group). The blood pressure (BP), heart rate (HR), SpO(2) and pH, PaCO(2), and HCO(3)(-) were monitored at 5 min and 1 h after anesthesia, before completion of the operation and at 1 h after the operation. The total operative time, dosage of propofol, awake time and body movement during the procedure were recorded. Compared with LMA and ETT groups, the MAC groups showed a significantly increased total dosage of propofol (66.07±5.41, 35.83±5.80, and 34.61±3.68 g·kg(-1)·min(-1), respectively, Pawake time (16.82±7.60, 4.31±1.32, and 3.73±1.33 min, P0.05). At 1 h after anesthesia, the pH in MAC group decreased markedly compared with that in LMA and ETT groups (PMAC group and remained so till the end of the surgery (P<0.05). Endotracheal tube placement is safer than laryngeal mask airway placement and monitored anesthesia care in patients with MR during APBMCT, and allows rapid onset of sedation with minimal cardiovascular responses, body movement and recovery, therefore is more suitable in the setting outside the operating room.

    2011-01-01

    The obese patient presents many challenges to both anesthesiologist and surgeon. A good understanding of the pathophysiologic effects of obesity and its anesthetic implications in the surgical setting is critical. The anesthesiologist must recognize increased risks and comorbidities inherent to the obese patient and manage accordingly, optimizing multisystem function in the perioperative period that leads to successful outcomes. Addressed from an organ systems approach, the purpose of this review is to provide surgical specialists with an overview of the anesthetic considerations of obesity. Minimally invasive surgery for the obese patient affords improved analgesia, postoperative pulmonary function, and shorter recovery times at the expense of a more challenging intraoperative anesthetic course. The physiologic effects of laparoscopy are discussed in detail. Although laparoscopy's physiologic effects on various organ systems are well recognized, techniques provide means for compensation and reversing such effects, thereby preserving good patient outcomes.

    The exact mechanism by which anesthetics induce cell membrane-mediated modifications is still an open question. Although the fluidization effect of the anesthetic molecules on the cellular membrane is widely recognized, it is not known if anesthetics show any preference for specific membrane domains, namely the lipid rafts. The importance of these membrane micro-domains derives from the fact that they have been associated with cell signaling pathways, as well as with specific drug interactions. The objective of this work is to contribute for the elucidation of this question through the comparison of the anesthetic interactions with membranes of various lipid compositions. Liposomes prepared with an equimolar mixture of POPC, sphingomyelin and cholesterol, were chosen as models for lipid rafts. The interactions of these liposomes with two local anesthetics, tetracaine and lidocaine, and one general anesthetic, propofol, were studied. The effect of cholesterol was investigated by comparing anesthetic interactions with POPC/SM liposomes and POPC/SM/CHOL liposomes. The following experimental techniques were used: quartz crystal microbalance with dissipation, differential scanning calorimetry and phosphorus nuclear magnetic resonance. Although the liposomes investigated by the different techniques are not in the same conditions, it is possible to assemble the information obtained from all experimental techniques employed to reach a general conclusion. Tetracaine interacts more with raftlike domains, lidocaine induces stronger modifications on POPC/SM liposomes and the results for propofol are not fully conclusive but it seems to be the least prone to lipid interactions. The results were compared with those obtained with DMPC-containing liposomes, reported in a previous work.

    2015-01-01

    From time immemorial, animals have served as models for humans. Like humans, animals too have to undergo several types of elective and emergency surgeries. Several anesthetic techniques and drugs used in humans are also used in animals. However, unlike humans, the animal kingdom includes a wide variety of species, breeds, and sizes. Different species have variable pharmacological responses, anatomy, temperament, behavior, and lifestyles. The anesthetic techniques and drugs have to suit different species and breeds. Nevertheless, there are several drugs and many peculiar anesthetic techniques used in animals but not in human beings. Keeping this in mind, literature was hand searched and electronically searched using the words "veterinary anesthesia," "anesthetic drugs and techniques in animals" using Google search engine. The interesting information so collected is presented in this article which highlights some challenging and amazing aspects of anesthetizing animals including the preanesthetic assessment, preparation, premedication, monitoring, induction of general anesthesia, intubation, equipment, regional blocks, neuraxial block, and perioperative complications.

    Llamas are anesthetized conveniently with guaifenesin thiamylal mixes, or, for short periods of time, with xylazine/ketamine. Small individuals must be accurately weighed. Estimating weight without experience is dangerous in this species. The greatest levels of safety and control, especially for critical patients, is afforded by inhalation anesthesia techniques using small animal equipment. All neonates and juveniles can be masked readily but in adults intravenous induction is most satisfactory. Intubation is aided by a long blade laryngoscope. Blood pressure monitoring is best accomplished with an arterial line in the ear artery. However, doppler equipment on the tail or distal leg usually works well.

  6. Injection techniques in the management of local pain.

    1996-01-01

    This is a review of local anesthetic (LA) injections and infiltrations particularly combined with 'needling' for management of local musculoskeletal pain. New techniques are described including preinjection blocks (PIBs) which consist of blocking the sensory input from an area prior to giving an injection. PIBs prevent pain which would be caused by needle penetration of sensitive tissue. Needling and infiltration (N and I) with 1% lidocaine has been performed after PIB in 179 tender spots (TSs), trigger points (TrPs), and muscle spasms by the author, in 123 patients with the goal to relieve pain and promote healing. The immediate effect after the procedure as well as long-term results from 1 week to 7 months have been evaluated independently by a physiatrist experienced with injections (Dr. Tae Mo Chang). N and I extending over the entire taut band of abnormal muscle fibers, caused effective relief of pain and functional improvement in tender spots (TSs), trigger points (TrPs) and in muscle spasm caused by a variety of conditions including: acute and chronic sports and work injuries, motor vehicle accidents, muscle and ligament sprains (supraspinous, sacroiliac), overuse and repetitive stress syndromes, tennis elbow; local injuries or radicular irritation; and local inflammations such as bursitis, tendinitis, and osteoarthritis; and traumatic dystrophy, a type of reflex sympathetic dystrophy. Needling and infiltration of trigger areas and tender spots is effective treatment in several conditions. Pre-injection blocks allow the performance of the N and I of tender areas without pain.

  7. Anesthetic Maintenance of Thyroid Surgery

    2008-01-01

    Full Text Available Thyroid diseases are most common in endocrinology. Thyrotoxicosis induces dysfunction of virtually all organs and systems, the blood circulatory system being subjected to considerable changes. Cardiovascular diseases affect not only the quality of life in a patient, but significantly increase a risk from surgery that is the only radical treatment. For this reason, most authors consider thyrotoxicosis to be a contraindication to elective surgical intervention. At the same time it is known that drug compensation of thyrotoxicosis may be attained in not all patients. In this case, the results of treatment and a patient’s safety during surgery depend on the type and quality of anesthetic protection. The capabilities of anesthetic maintenance of thyroid surgery have recently expanded substantially. The paper deals with the preparation of patients with thyrotoxicosis for surgical intervention and the perioperative management of these patients. Key words: thyroid, toxic goiter, thyrotoxicosis, premedication, anesthetic mode, sevoflurane, xenon.

    Full Text Available It is well known that both management control systems (MCSs and operations management (OM are related to firm performance; however, an integrated st udy that involves MCS and OM within the context of firm performance is still lacking. This research aimed to examine the relationships among the use of MCSs and OM techniques and firm performance in the Brazilian auto parts industry. Simons’ levers of cont rol framework was used to characterise the uses of MCSs, and OM techniques, such as total quality management (TQM and continuous improvement programmes, were adopted. The results obtained through the structural equation modelling indicated that the diagno stic use of MCSs is positively associated with the goals of cost reduction. In addition, the interactive use of MCSs is positively associated with the objectives of introducing new products, which is consistent with previous research. Additionally, OM tech niques are positively related to cost reduction but have no direct relationship with the introduction of new products.

    ABSTRACT A three-year old Thoroughbred racehorse was anesthetized with sevoflurane and oxygen inhalation anesthesia combined with constant rate infusion (CRI) of alfaxalone-medetomidine for internal fixation of a third metacarpal bone fracture. After premedication with intravenous (IV) injections of medetomidine (6.0 µg/kg IV), butorphanol (25 µg/kg IV), and midazolam (20 µg/kg IV), anesthesia was induced with 5% guaifenesin (500 ml/head IV) followed immediately by alfaxalone (1.0 mg/kg IV). Anesthesia was maintained with sevoflurane and CRIs of alfaxalone (1.0 mg/kg/hr) and medetomidine (3.0 µg/kg/hr). The total surgical time was 180 min, and the total inhalation anesthesia time was 230 min. The average end-tidal sevoflurane concentration during surgery was 1.8%. The mean arterial blood pressure was maintained above 70 mmHg throughout anesthesia, and the recovery time was 65 min. In conclusion, this anesthetic technique may be clinically applicable for Thoroughbred racehorses undergoing a long-time orthopedic surgery. PMID:28955163

    Full Text Available Purpose: To date, there has been no comparison of outcomes in women undergoing anesthesia for in vitro fertilization (IVF oocyte retrieval for the purpose of pre-implantation genetic diagnosis (PGD because of their or their partner′s genetic disease relative to the outcome in women requiring IVF because of fertility issues. Materials and Methods: A prospective observational study, wherein all demographic and anesthetic management data were collected from IVF and PGD units′ records for a 6-month period. Descriptive analyses and parametric tests were employed. Results: There were 307 cases IVF and 76 cases PGD: most (97.4% and 99.7%, respectively received general anesthesia with propofol and fentanyl ± dipyrone (90.5% and 93.3%, respectively with no adverse effects. The only statistically significant difference between IVF and PGD groups that was potentially clinically significant was post-procedure recovery time (23.0 ± 20.4 vs. 29.4 ± 35.8 min, respectively; P < 0.0001, but is explainable as greater caution by Anesthesiologists for higher-risk PGD cases having autosomal dominant diseases that may impact anesthesia management (myotonic dystrophy, neurofibromatosis, Marfan′s; two of these cases also recovered in the general post-anesthesia care unit, as a precaution for early diagnosis and treatment of potential post-procedural complication. Conclusions: Results of this first-ever survey of anesthesia for PGD compared with IVF cases imply that propofol-and-fentanyl-based anesthesia is safe and can be recommended, bearing in mind that with patients who have autosomal dominant diseases impacting anesthetic management it is prudent to be more cautious post-recovery.

    Full Text Available BACKGROUND: The rare congenital heart defect of Ebstein’s anomaly is characterized by downward displacement and elongation of the tricuspid valve with poorly contractile right ventricle, an enlarged right atrium along with tricuspid regurgitation. It is frequently associated with intracardiac shunting, pulmonary hypertension, cardiac dysrhythmias, cyanosis and particularly associated with Wolf-Parkinson-White syndrome (up to 20 % of patients. Supra ventricular and ventricular arrythmias are common. Congestive heart failure and sudden collapse are the most common causes of death. The complications following thyroid surgery are rare due to better preoperative preparations and proper surgical techniques, however, complications like hematoma formation and recurrent laryngeal nerve injury are known to cause airway obstruction and can be fatal. Here we report the successful management of a 45 year old euthyroid patient, a known case of Ebstein’s anomaly who underwent Hemithyroidectomy under General anaesthesia (G.A Perioperative management was uncomplicated with good hemodynamic stability and patient was discharged without any untoward problem.

    2016-01-01

    In this thesis, two different optical management techniques for organics based solar cells are explored. The first part is focused on the development of a textured rear reflector for OPVs. The use of textured reflector (TR) facilitates an increase in the optical path length along with light trapping within the active layer. TR was fabricated through a relatively simpler technique by depositing metal films over a microlens array (MLA). Zinc oxide nanoparticles were used to minimize the shadowing effect. Using TR, enhancements in short-circuit current density and power conversion efficiencies up to 10-25% were demonstrated for a polymer based organic solar cell. The second part is focused on improving the effectiveness of MLA incorporation in OPVs. The increase in path length achieved using MLA can be improved by increasing the refractive index of MLA and incorporating MLA directly on the transparent electrode instead of glass substrate. This approach could avoid the optical losses occurring at the interface be...

    A hardcopy or paper cognitive aid has been shown to improve performance during the management of simulated local anesthetic systemic toxicity (LAST) when given to the team leader. However, there remains room for improvement to ensure a system that can achieve perfect adherence to the published guidelines for LAST management. Recent research has shown that implementing a checklist via a designated reader may be of benefit. Accordingly, we sought to investigate the effect of an electronic decision support tool (DST) and designated "Reader" role on team performance during an in situ simulation of LAST. Participants were randomized to Reader + DST (n = 16, rDST) and Control (n = 15, memory alone). The rDST group received the assistance of a dedicated Reader on the response team who was equipped with an electronic DST. The primary outcome measure was adherence to guidelines. For overall and critical percent correct scores, the rDST group scored higher than Control (99.3% vs 72.2%, P Reader with an electronic DST improved adherence to guidelines in the management of an in situ simulation of LAST. Such tools are promising in the future of medicine, but further research is needed to ensure the best methods for implementing them in the clinical arena.

    Full Text Available Background: Endoscopic retrograde cholangiopancreatography (ERCP is a unique diagnostic and therapeutic procedure performed in high risk patients in prone/semi-prone position. Propofol based deep sedation has emerged as the method of choice however, the ability to predict possible complications is yet un-explored. Aims: The present study aimed to evaluate known high risk-factors for general anesthesia (American Society of Anesthesiologists (ASA status, body mass index (BMI, and Mallampati class for their ability to affect outcomes in ERCP patients. Study Design: Retrospective data of 653 patients who underwent ERCP during a period of 26 months at university hospital of Pennsylvania was reviewed. Patient-specific and procedure specific data was extracted. Desaturation was defined by fall of pulse oximeter saturation below 95% and its relation to patient specific high risk-factors was analyzed. Results: Only 45 patients had transient de-saturation below 95% without any residual sequlae. No statistically significant relation between desaturation episodes and patients higher ASA status or BMI or modified Mallampati (MMP class was found. Despite 60% patients being ASA III/IV none required emergency intubation or procedural interruption. Optimal oxygenation and airway patency was maintained with high degree of success using simple airway maneuvers or conduit devices (nasal/oral trumpet with oxygen supplementation in all patients. Conclusions: Unlike general anesthesia, pre-operative patient ASA status, higher MMP or increasing BMI does not bear relation with likelihood of patients desaturating during ERCP. In presence of vigilant apnea monitoring and careful dose titration of maintenance anesthetics with airway conduits, general anesthesia, emergency intubations, and procedure interruptions can be avoided.

    Aortocaval fistula is a rare complication of ruptured abdominal aortic aneurysm. We report anesthetic management of a patient with aortocaval fistula caused by rupture of a huge abdominal aortic aneurysm into the inferior vena cava. A 51-year-old man who had complained of low back pain and general fatigue was referred to our hospital because of his liver damage. Aortocaval fistula due to rupture of a huge abdominal aortic aneurysm was diagnosed from physical examination, enhanced computed tomography and color Doppler ultrasonography. Anesthesia was induced with propofol and rocuronium, and was maintained with sevoflurane and remifentanil. After induction of anesthesia, the central venous pressure and cardiac index showed remarkably high values because of arteriovenous shunt. When the aneurysm was incised after the clamping of the abdominal aorta, massive venous bleeding occurred from the fistula and caused severe hypotension. Blood pressure recovered by digital compression of the bleeding point and the use of an autotransfusion device. After the repair of the aortocaval fistula, the hemodynamics became stable. The patient had a high output but a good cardiac function in preoperative examination. Therefore anesthesia was managed successfully without worsening high-output heart failure.

  7. Microgrids: Energy management by loss minimization technique

    Directory of Open Access Journals (Sweden)

    A. K. Basu, S. Chowdhury, S.P. Chowdhury

    2011-03-01

    Full Text Available Energy management is a techno-economic issue, which dictates, in the context of microgrids, how optimal investment in technology front could bring optimal power quality and reliability (PQR of supply to the consumers. Investment in distributed energy resources (DERs, with their connection to the utility grid at optimal locations and with optimal sizes, saves energy in the form of line loss reduction. Line loss reduction is the indirect benefit to the microgrid owner who may recover it as an incentive from utility. The present paper focuses on planning of optimal siting and sizing of DERs based on minimization of line loss. Optimal siting is done, here, on the loss sensitivity index (LSI method and optimal sizing by differential evolution (DE algorithms, which is, again, compared with particle swarm optimization (PSO technique. Studies are conducted on 6-bus and 14-bus radial networks under islanded mode of operation with electric demand profile. Islanding helps planning of DER capacity of microgrid, which is self-sufficient to cater its own consumers without utility’s support.

  8. Anesthetic issues for robotic cardiac surgery

    Full Text Available As innovative technology continues to be developed and is implemented into the realm of cardiac surgery, surgical teams, cardiothoracic anesthesiologists, and health centers are constantly looking for methods to improve patient outcomes and satisfaction. One of the more recent developments in cardiac surgical practice is minimally invasive robotic surgery. Its use has been documented in numerous publications, and its use has proliferated significantly over the past 15 years. The anesthesiology team must continue to develop and perfect special techniques to manage these patients perioperatively including lung isolation techniques and transesophageal echocardiography (TEE. This review article of recent scientific data and personal experience serves to explain some of the challenges, which the anesthetic team must manage, including patient and procedural factors, complications from one-lung ventilation (OLV including hypoxia and hypercapnia, capnothorax, percutaneous cannulation for cardiopulmonary bypass, TEE guidance, as well as methods of intraoperative monitoring and analgesia. As existing minimally invasive techniques are perfected, and newer innovations are demonstrated, it is imperative that the cardiothoracic anesthesiologist must improve and maintain skills to guide these patients safely through the robotic procedure.

    This paper discusses human spaceflight fault management operations. Fault detection and response capabilities available in current US human spaceflight programs Space Shuttle and International Space Station are described while emphasizing system design impacts on operational techniques and constraints. Preflight and inflight processes along with products used to anticipate, mitigate and respond to failures are introduced. Examples of operational products used to support failure responses are presented. Possible improvements in the state of the art, as well as prioritization and success criteria for their implementation are proposed. This paper describes how the architecture of a command and control system impacts operations in areas such as the required fault response times, automated vs. manual fault responses, use of workarounds, etc. The architecture includes the use of redundancy at the system and software function level, software capabilities, use of intelligent or autonomous systems, number and severity of software defects, etc. This in turn drives which Caution and Warning (C&W) events should be annunciated, C&W event classification, operator display designs, crew training, flight control team training, and procedure development. Other factors impacting operations are the complexity of a system, skills needed to understand and operate a system, and the use of commonality vs. optimized solutions for software and responses. Fault detection, annunciation, safing responses, and recovery capabilities are explored using real examples to uncover underlying philosophies and constraints. These factors directly impact operations in that the crew and flight control team need to understand what happened, why it happened, what the system is doing, and what, if any, corrective actions they need to perform. If a fault results in multiple C&W events, or if several faults occur simultaneously, the root cause(s) of the fault(s), as well as their vehicle-wide impacts, must be

    Placenta previa totalis can cause life-threatening massive postpartum hemorrhage, and careful anesthetic management is essential. Preventive uterine artery embolization (UAE) before placental expulsion was introduced to reduce postpartum bleeding in cases of placenta previa totalis. We describe the case of a 40-year-old woman (gravida 0, para 0) with placenta previa totalis and uterine myomas who underwent intraoperative UAE, which was preoperatively planned at the strong recommendation of the anesthesiologist, immediately after delivery of a fetus and before removal of the placenta during cesarean delivery under spinal-epidural anesthesia. After confirming embolization of both uterine arteries, removal of the placenta resulted in moderate bleeding. The estimated blood loss was 2.5 L, and 5 units of red blood cells were transfused. The parturient was discharged uneventfully on postoperative day 4. This case shows that the bleeding risk is reduced by intraoperative UAE in a patient with placenta previa totalis, and anesthesiologists have an important role in a multidisciplinary team approach.

    Content management systems use various strategies to store and manage information. One of the most usual methods encountered in commercial products is to make use of the file system to store the raw content information, while the associated metadata is kept synchronized in a relational database management system. This strategy has its advantages but we believe it also has significant limitations which should be addressed and eventually solved. In this paper we propose an alternative method of storing and managing content aiming at finding solutions for current limitations both in terms of functional and nonfunctional requirements.

    2010-01-01

    Full Text Available Antiphospholipid antibody syndrome (APLAS characterises a clinical condition of arterial and venous thrombosis associated with phospholipids directed antibodies. APLAS occurs in 2% of the general population. However, one study demonstrated that 7.1% of hospitalised patients were tested positive for at least one of the three anticardiolipin antibody idiotype. Antiphospholipid antibodies often inhibit phospholipids dependent coagulation in vitro and interfere with laboratory testing of hemostasis. Therefore, the management of anticoagulation during cardiopulmonary bypass can be quite challenging in these patients. Here, we present a case of right atrial mass removal and pulmonary thrombectomy in a patient of APLAS.

    A 2-year-and-4-month-old female infant, 12 kg in weight and 90 cm in height fell off from a table, which was about 1 m height with a toothbrush in her mouth without her parents noticing. Urgent CT scan showed that it penetrated the left side of her oropharyngeal wall to the bifurcation of her right carotid artery. According to the initial assessment, carotid artery seemed intact and there seemed to be no sign of CNS involvement. She underwent general anesthesia for further investigation and operation. We could detect vocal code with ease by inserting Glidescope between her tongue and the toothbrush. After the intubation, we administered fentanyl 25 μg rocuronium 15 mg and sevoflulane 3-5% to her, and then she underwent arteriography. The neurosurgeon found no sign of major arterial injury nor traumatic aneurysm nor CNS involvement. She went to the ICU intubated after the removal of the toothbrush. She was extubated 5 days after operation. One of the benefits of the Glidescope is that we can share the visual image, and we chose it this time. When we expect a difficult airway during management for oropharyngeal trauma, we have to consider the way to manage the airway.

    Swain, Amlan; Nag, Deb Sanjay; Sahu, Seelora; Samaddar, Devi Prasad

    2017-01-01

    Although beneficial in acute and chronic pain management, the use of local anaesthetics is limited by its duration of action and the dose dependent adverse effects on the cardiac and central nervous system. Adjuvants or additives are often used with local anaesthetics for its synergistic effect by prolonging the duration of sensory-motor block and limiting the cumulative dose requirement of local anaesthetics. The armamentarium of local anesthetic adjuvants have evolved over time from classical opioids to a wide array of drugs spanning several groups and varying mechanisms of action. A large array of opioids ranging from morphine, fentanyl and sufentanyl to hydromorphone, buprenorphine and tramadol has been used with varying success. However, their use has been limited by their adverse effect like respiratory depression, nausea, vomiting and pruritus, especially with its neuraxial use. Epinephrine potentiates the local anesthetics by its antinociceptive properties mediated by alpha-2 adrenoreceptor activation along with its vasoconstrictive properties limiting the systemic absorption of local anesthetics. Alpha 2 adrenoreceptor antagonists like clonidine and dexmedetomidine are one of the most widely used class of local anesthetic adjuvants. Other drugs like steroids (dexamethasone), anti-inflammatory agents (parecoxib and lornoxicam), midazolam, ketamine, magnesium sulfate and neostigmine have also been used with mixed success. The concern regarding the safety profile of these adjuvants is due to its potential neurotoxicity and neurological complications which necessitate further research in this direction. Current research is directed towards a search for agents and techniques which would prolong local anaesthetic action without its deleterious effects. This includes novel approaches like use of charged molecules to produce local anaesthetic action (tonicaine and n butyl tetracaine), new age delivery mechanisms for prolonged bioavailability (liposomal

    Shirgoska, Biljana; Netkovski, Jane

    2012-09-01

    The purpose of this review is to compare old conventional techniques and devices for difficult airway management and new sophisticated techniques and devices. Recent techniques and devices are defined as the American Society of Anesthesiology (ASA) practice guidelines for the management of difficult airway, published in 1992, reviewed in 1993 and updated in 2003. According to ASA, the techniques for difficult airway management are divided into techniques for difficult intubation and techniques for difficult ventilation. Awake fiberoptic intubation is the technique of choice for difficult airway management prescribed by the World Health Organization document for patient safety in the operating theater. Conventional techniques for intubation used direct visualization. The new generation of devices does not require direct visualization of the vocal cords for endotracheal tube placement. They allow better glottis view and successful endotracheal placement of the tube with indirect laryngoscopy. New intubation devices such as video laryngoscopes facilitate endotracheal intubation by indirect visualization of glottis structures without aligning the oral, pharyngeal and laryngeal axes in patients with cervical spine abnormality. Video laryngoscopes such as V-Mac and C-Mac, Glide scope, McGrath, Airway Scope, Airtraq, Bonfils and Bullard laryngoscope are widely available at the market. Airway gadgets are lighted stylets and endotracheal tube guides. The principal conclusion of this review is that utilization of these devices can be easily learned. The technique of indirect laryngoscopy is currently used for managing difficult airway in the operating room as well as for securing the airway in daily anesthesia routine.

    Full Text Available The advancement in the technology of the cochlear implants has resulted in increasing trend of cochlear implantation in both the children and elderly population. The anesthesiologist is faced with the task of smoothly conducting the surgery without any interference in the stimulation techniques used. The preoperative evaluation is mainly focused on the presence of any congenital anomalies in these patients which may affect anesthetic technique. The reduction of anxiety of the patient as well as the parents of small children is an important aspect of the preoperative visit. Intraoperatively the anesthetic technique chosen should not interfere with the stimulation of the cochlear implant electrode assembly. The postoperative management is mainly focused at prevention of agitation and good analgesia. A close cooperation between the surgeon and the anesthesiologist is essential for a positive outcome in this surgery. The current review focuses on the important anesthesia aspects related to cochlear implant surgery.

    Many women would like to avoid pharmacological or invasive methods of pain management in labour and this may contribute towards the popularity of complementary methods of pain management. This review examined currently available evidence supporting the use of relaxation therapies for pain management in labour. To examine the effects of relaxation methods for pain management in labour on maternal and perinatal morbidity. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2010), The Cochrane Complementary Medicine Field's Trials Register (November 2011), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2010, Issue 4), MEDLINE (1966 to 30 November 2010), CINAHL (1980 to 30 November 2010), the Australian and New Zealand Clinical Trial Registry (30 November 2010), Chinese Clinical Trial Register (30 November 2010), Current Controlled Trials (30 November 2010), ClinicalTrials.gov, (30 November 2010) ISRCTN Register (30 November 2010), National Centre for Complementary and Alternative Medicine (NCCAM) (30 November 2010) and the WHO International Clinical Trials Registry Platform (30 November 2010). Randomised controlled trials comparing relaxation methods with standard care, no treatment, other non-pharmacological forms of pain management in labour or placebo. Three review authors independently assessed trials for inclusion and extracted data. Data were checked for accuracy. Two review authors independently assessed trial quality. We attempted to contact study authors for additional information. We included 11 studies (1374 women) in the review. Relaxation was associated with a reduction in pain intensity during the latent phase (mean difference (MD) -1.25, 95% confidence interval (CI) -1.97 to -0.53, one trial, 40 women) and active phase of labour (MD -2.48, 95% CI -3.13 to 0.83, two trials, 74 women). There was evidence of improved outcomes from relaxation instruction with increased satisfaction with pain

    Modern electronic systems used in space must be reliable and efficient with thermal management unaffected by outer space constraints. Current thermal management techniques are not sufficient for the increasing waste heat dissipation of novel electronic technologies. Many advanced thermal management techniques have been developed in recent years that have application in high power electronic systems. The benefits and limitations of emerging cooling technologies are discussed. These technologies include: liquid pumped devices, mechanically pumped two-phase cooling, capillary pumped evaporative cooling, and thermoelectric devices. Currently, liquid pumped devices offer the most promising alternative for electronics thermal control.

    Nizharadze, N; Mamaladze, M; Chipashvili, N; Vadachkoria, D

    2011-01-01

    Local anesthesia forms the foundation of pain control techniques in clinical dentistry. Within the rich local anesthetic drugs available in dentistry for the prevention and management of pain 4% articaine solutions achieve highest level of anesthetic potency and lowest systemic toxicity in all clinical situations, prior to its superlative physicochemical characteristics and the pharmacological profile. These are - low lipid solubility, high plasma protein binding rate, fast metabolization, fast elimination half time; low blood level. Articaine inactivates in both ways: in the liver and the blood serum. It has good spreading through tissues. Thus, articaine seems to be the local anesthetic of first choice in tissues with suppurative inflammation, for adults, children (over 4), elderly, pregnant women, breastfeeding women, patients suffering from hepatic disorders and renal function impairment. In Articaine solutions (1: 200,000) epinephrine is in low concentration, thus in patients at high risk adverse responses are maximally decreased. In these patients articaine should be used with careful consideration of risk/benefit ratio. Articaine solutions must not be used in persons who are allergic or hypersensitive to sulphite, due to content of Sodium metabisulfite as vasoconstrictor's antioxidant in it. Incidence of serious adverse effects related to dental anesthesia with articaine is very low. Toxic reactions are usually due to an inadvertent intravascular injection or use of excessive dose. To avoid overdoses maximum recommendation dose (MRD) must not be exceeded and aspiration test always performed prior all LA injections. In these article we introduce new graphs providing a quick and effect way to determine maximum LA dose. If the overdose reactions develop, adherence to the basic step of emergency management with end to a successful outcome in virtually all cases.

    2015-04-01

    Full Text Available The management of a patient presenting with unsatisfactory labor epidural analgesia poses a severe challenge for the anesthetist wanting to provide safe anesthetic care for a cesarean delivery. Early recognition of unsatisfactory labor analgesia allows for replacement of the epidural catheter. The decision to convert labor epidural analgesia to anesthesia for cesarean delivery is based on the urgency of the cesarean delivery, airway examination, and the existence of a residual sensory and motor block.  We suggest an algorithm which is implemented in our department, based on the urgency of the cesarean delivery.

    Surgery patients in Japan undergo routine spirometry testing prior to general anesthesia. The use of a flow sensor during general anesthesia has recently become common. However, it is not certain whether the information derived from flow-volume curves is being adequately used for mechanical ventilation management during general anesthesia. So far, there have been no attempts to calculate airway resistance using flow-volume curves. Therefore, we performed a prospective, observational study to investigate the relationship between pre-anesthetic and intra-anesthetic airway resistance in patients scheduled for surgery under general anesthesia. We calculated pre-anesthetic and intra-anesthetic airway resistance in each patient, based on the slopes of flow-volume curves obtained prior to and during general anesthesia. We also calculated endotracheal tube resistance to correct the intra-anesthetic airway resistance values calculated. A total of 526 patients were included in the study, and 98 patients had a forced expiratory volume in the first second/forced vital capacity ratio of mechanical ventilation (p = 0.48). Pre-anesthetic and intra-anesthetic airway resistance values were closer to each other in patients without airflow obstruction, with a mean difference < 1.0 cmH2O L-1s-1, than in those with airflow obstruction, although these respiratory parameters were significantly different (p < 0.001). Intra-anesthetic airway resistance was not related to the FEV1/FVC ratio, regardless of the degree to which the FEV1/FVC ratio reflected pre-anesthetic airway resistance. As compared with patients with airflow obstruction, the mean difference between pre-anesthetic and intra-anesthetic airway resistance was small in patients without airflow obstruction. PMID:28212451

  19. Anesthetics drug pharmacodynamics.

    Bischoff, P; Schneider, G; Kochs, E

    2008-01-01

    Anesthesia cannot be defined in an unambiguous manner. The essential components of general anesthesia are absence of consciousness and pain. This translates into two particular qualities: (1) sedation and hypnosis, i.e., mental blockade and (2) analgesia/antinociception, i.e., sensory blockade. Anesthetic actions on these two subcomponents are difficult to separate. On the one hand, very few anesthetics act exclusively on one of these components. On the other hand, these components are closely related to each other. Unconsciousness prevents (conscious) perception of pain, and nociception may serve as an arousal stimulus and change the level of sedation and hypnosis. The art of anesthesia lies in adequate dosing of drugs to reach both mental and sensory blockade. Drug administration can be based on pharmacokinetic considerations. Pharmacokinetic models allow an estimation of what happens to the administered drug in the body. Models with an effect site compartment may facilitate a tailored administration of anesthetic drugs. Finally, the quantification of pharmacodynamic effects allows a precise titration of drugs. Clinical assessment of mental blockade is often dichotomous, and therefore not very helpful to guide drug administration. Several scoring systems exist, but once consciousness is lost they become less reliable, in particular because reaction to stimuli is assessed, which mixes assessment of mental blockade with assessment of sensory blockade. Clinical assessment of analgesia requires a conscious patient, so antinociception is difficult to measure. Several methods of objective quantification on the basis of electrical brain activity are discussed including EEG and evoked potentials. Despite numerous indexes of the hypnotic component of anesthesia, there is no parameter that unambiguously quantifies the level of mental or sensory blockade.

    Malamed, Stanley F

    2006-12-01

    Local anesthetics are the safest most effective drugs in medicine for the control and management of pain. They also represent the most important drugs in dentistry. Today, dentistry has a spectrum of local anesthetics that permit pain control to be tailored to the specific needs of the patient: short-, intermediate-, and long-acting drugs. Bupivacaine has become a standard part of the armamentarium for postsurgical pain control while articaine has become the second-most used local anesthetic in the United States since its introduction in 2000. Despite an increase in anecdotal reports of paresthesia since articaine's introduction there is yet, no supporting scientific evidence.

    Pancreatic cystic lesions can be benign, premalignant or malignant. The recent increase in detection and tremendous clinical variability of pancreatic cysts has presented a significant therapeutic challenge to physicians. Mucinous cystic neoplasms are of particular interest given their known malignant potential. This review article provides a brief but comprehensive review of premalignant pancreatic cystic lesions with advanced endoscopic ultrasound (EUS) management approaches. A comprehensive literature search was performed using PubMed, Cochrane, OVID and EMBASE databases. Preneoplastic pancreatic cystic lesions include mucinous cystadenoma and intraductal papillary mucinous neoplasm. The 2012 International Sendai Guidelines guide physicians in their management of pancreatic cystic lesions. Some of the advanced EUS management techniques include ethanol ablation, chemotherapeutic (paclitaxel) ablation, radiofrequency ablation and cryotherapy. In future, EUS-guided injections of drug-eluting beads and neodymium:yttrium aluminum agent laser ablation is predicted to be an integral part of EUS-guided management techniques. In summary, International Sendai Consensus Guidelines should be used to make a decision regarding management of pancreatic cystic lesions. Advanced EUS techniques are proving extremely beneficial in management, especially in those patients who are at high surgical risk. PMID:27574295

    The guinea pig is a common animal model that is used in biomedical research to study a variety of systems, including hormonal and immunological responses, pulmonary physiology, corticosteroid response and others. However, because guinea pigs are evolutionarily a prey species, they do not readily show behavioral signs of disease, which can make it difficult to detect illness in a laboratory setting. Minimally invasive blood tests, such as complete blood counts and plasma biochemistry assays, are useful in both human and veterinary medicine as an initial diagnostic technique to rule in or rule out systemic illness. In guinea pigs, phlebotomy for such tests often requires that the animals be anesthetized first. The authors evaluated hematological and plasma biochemical effects of two anesthetic agents that are commonly used with guinea pigs in a research setting: isoflurane and a combination of ketamine and xylazine. Hematological and plasma biochemical parameters were significantly different when guinea pigs were under either anesthetic, compared to when they were unanesthetized. Plasma proteins, liver enzymes, white blood cells and red blood cells appeared to be significantly altered by both anesthetics, and hematological and plasma biochemical differences were greater when guinea pigs were anesthetized with the combination of ketamine and xylazine than when they were anesthetized with isoflurane. Overall these results indicate that both anesthetics can significantly influence hematological and plasma biochemical parameters in guinea pigs.

    Inhalation sedation utilizing nitrous oxide-oxygen has been a primary technique in the management of dental fears and anxieties for more than 150 years and remains so today. Though other, more potent, anesthetics have been introduced, nitrous oxide is still the most used gaseous anesthetic in the world. Administered properly with well-maintained equipment, the nitrous oxide-oxygen technique has an extremely high success rate coupled with a very low rate of adverse effects and complications.

    2000-01-01

    This study aimed to identify the techniques used by manipulative physiotherapists in the management of headaches. Two hundred and two patients with headache presented to 44 Victorian trained manipulative physiotherapists (MPTs) who completed questionnaires to determine techniques used. Upper cervical (O-C3) passive accessory intervertebral movement was the most frequently used technique (84.7 per cent). Techniques such as manipulation (42.1 per cent), soft tissue massage (35.6 per cent), postural education/advice (30.2 per cent), muscle stretches (29.2 per cent), traction (26.7 per cent) and postural exercises (21.3 per cent) were usually introduced during the initial consultation, whereas passive physiological intervertebral movements (17.3 per cent), muscle retraining (16.8 per cent) and neural techniques (5.4 per cent) were more commonly introduced in later sessions. The low incidence of muscle retraining was surprising and may not reflect contemporary practice. The results indicate that the clinicians studied employ a diverse range of techniques in the management of headaches.

    Lee, Hyeon Jeong; Yeomans, David C

    2014-11-01

    Pain is difficult to investigate and difficult to treat, in part, because of problems in quantification and assessment. The use of opioids, combined with classic anesthetics to maintain hemodynamic stability by controlling responses to intraoperative painful events has gained significant popularity in the anesthetic field. However, several side effects profiles concerning perioperative use of opioid have been published. Over the past two decades, many concerns have arisen with respect to opioid-induced hyperalgesia (OIH), which is the paradoxical effect wherein opioid usage may decrease pain thresholds and increase atypical pain unrelated to the original, preexisting pain. This brief review focuses on the evidence, mechanisms, and modulatory and pharmacologic management of OIH in order to elaborate on the clinical implication of OIH.

    2003-10-01

    The laser Doppler flowmetry technique has recently been used to report a significant transient increase of the cutaneous blood flow signal when a local non-noxious pressure is applied progressively on the skin (11.1 Pa/s). The present work analyses the dynamic characteristics of this vasodilatory reflex response on anaesthetised rats. A de-noising algorithm using wavelets is proposed to obtain accurate values of these dynamic characteristics. The blood flow peak and the time to reach this peak are computed on the de-noised recordings. The results show that the mean time to reach the peak of perfusion is 85.3 s (time t = 0 at the beginning of the pressure application). The mean peak value is 188.3 arbitrary units (a.u.), whereas the mean value of the perfusion before the pressure application is 113.4 a.u. The mean minimum value obtained at the end of the experiment is 60.7 a.u. This latter value is, on the average, reached 841.3 s after the beginning of the pressure application. The comparison of the dynamic characteristics, computed with the de-noising algorithm on signals obtained in other situations, will give a better understanding on some cutaneous lesions such as those present on diabetic people.

    To describe an ''indirect'' cervical nerve root injection technique with a dorsal approach that should carry less inherent risk than the ''direct'' cervical transforaminal injection approach, and to compare the immediate post-injection results of the two procedures. The indirect and direct cervical nerve root injection procedures are described in detail. Fifty-three consecutive patients receiving the indirect nerve root injections during 2009-2010 were age- and gender-matched to 53 patients who underwent direct transforaminal nerve root injections performed in 2006. Pain level data were collected immediately before and 20-30 min after each procedure. The percentages of pain change in the two groups were compared using the unpaired Student's t test. Fifty-two men (mean age 49) and 54 women (mean age 55) were included. The mean percentage of pain reduction for patients receiving indirect nerve root injections was 38.4% and for those undergoing the direct nerve root injections approach it was 43.2%. This was not significantly different (P = 0.455). No immediate or late adverse effects were reported after either injection procedure. The indirect cervical nerve root injection procedure is a potentially safer alternative to direct cervical transforaminal nerve root injections. The short-term pain reduction is similar using the two injection methods. (orig.)

  11. TECHNIQUE OF OPTIMAL AUDIT PLANNING FOR INFORMATION SECURITY MANAGEMENT SYSTEM

    2014-03-01

    Full Text Available Complication of information security management systems leads to the necessity of improving the scientific and methodological apparatus for these systems auditing. Planning is an important and determining part of information security management systems auditing. Efficiency of audit will be defined by the relation of the reached quality indicators to the spent resources. Thus, there is an important and urgent task of developing methods and techniques for optimization of the audit planning, making it possible to increase its effectiveness. The proposed technique gives the possibility to implement optimal distribution for planning time and material resources on audit stages on the basis of dynamics model for the ISMS quality. Special feature of the proposed approach is the usage of a priori data as well as a posteriori data for the initial audit planning, and also the plan adjustment after each audit event. This gives the possibility to optimize the usage of audit resources in accordance with the selected criteria. Application examples of the technique are given while planning audit information security management system of the organization. The result of computational experiment based on the proposed technique showed that the time (cost audit costs can be reduced by 10-15% and, consequently, quality assessments obtained through audit resources allocation can be improved with respect to well-known methods of audit planning.

The purpose of the workshop, which was sponsored by the SC/Advanced Scientific Computing Research (ASCR) program and the National Nuclear Security Administration (NNSA)/Advanced Simulation and Computing (ASC) program, was to assess current and emerging techniques, practices, and lessons learned for effectively identifying, understanding, managing, and mitigating the risks associated with acquiring leading-edge computing systems at high-performance computing centers (HPCCs). Representatives from fifteen high-performance computing (HPC) organizations, four HPC vendor partners, and three government agencies attended the workshop. The overall workshop findings were: (1) Standard risk management techniques and tools are in the aggregate applicable to projects at HPCCs and are commonly employed by the HPC community; (2) HPC projects have characteristics that necessitate a tailoring of the standard risk management practices; (3) All HPCC acquisition projects can benefit by employing risk management, but the specific choice of risk management processes and tools is less important to the success of the project; (4) The special relationship between the HPCCs and HPC vendors must be reflected in the risk management strategy; (5) Best practices findings include developing a prioritized risk register with special attention to the top risks, establishing a practice of regular meetings and status updates with the platform partner, supporting regular and open reviews that engage the interests and expertise of a wide range of staff and stakeholders, and documenting and sharing the acquisition/build/deployment experience; and (6) Top risk categories include system scaling issues, request for proposal/contract and acceptance testing, and

    Despite recent advancements in the nonsurgical treatment for Dupuytren contracture, a number of patients remain poor nonsurgical candidates or elect for surgical management. The traditional McCash technique releases contractures while leaving open palmar wounds. Although successful in alleviating contractures, these wounds are traditionally large, transverse incisions across the palm. A modification of this technique has been performed that permits the surgeon to utilize smaller wounds while eliminating debilitating contractures.

    Full Text Available The lips form the frame of a smile and define the esthetic zone. Excessive gingival display during smile is often referred to as "gummy smile". A successful management of excessive gingival display with lip repositioning procedure has shown excellent results. The procedure involves removing a strip of partial thickness mucosa from maxillary vestibule, then suturing it back to the lip mucosa at the level of mucogingival junction. This technique results in restricted muscle pull and a narrow vestibule, thereby reducing the gingival display. In this case gummy smile was treated by modification of Rubinstein and Kostianovsky′s surgical lip repositioning technique which resulted in a harmonious smile.

    The search operation of spatial data was a principal operation in existent spatial database management system, but the update operation of spatial data such as tracking are occurring frequently in the spatial database management system recently. So, necessity of concurrency improvement among transactions is increasing. In general database management system, many techniques have been studied to solve concurrency problem of transaction. Among them, multi-version algorithm does to minimize interference among transactions. However, to apply existent multi-version algorithm to improve concurrency of transaction to spatial database management system, the waste of storage happens because it must store entire version for spatial record even if only aspatial data of spatial record is changed. This paper has proposed the record management techniques to manage separating aspatial data version and spatial data version to decrease waste of storage for record version and improve concurrency among transactions.

    Oral opioid analgesics have been used for management of peri- and postoperative analgesia in patients undergoing axillary dissection. The axillary region is a difficult zone to block and does not have a specific regional anesthesia technique published that offers its adequate blockade. After institutional review board approval, anatomic and radiological studies were conducted to determine the deposition and spread of methylene blue and local anesthetic injected respectively into the axilla via the thoracic inter-fascial plane. Magnetic Resonance Imaging studies were then conducted in 15 of 34 patients scheduled for unilateral breast surgery that entailed any of the following: axillary clearance, sentinel node biopsy, axillary node biopsy, or supernumerary breasts, to ascertain the deposition and time course of spread of solution within the thoracic interfascial plane in vivo. Radiological and cadaveric studies showed that the injection of local anesthetic and methylene blue via the thoracic inter-fascial plane, using ultrasound guide technique, results in reliable deposition into the axilla. In patients, the injection of the local anesthetic produced a reliable axillary sensory block. This finding was supported by Magnetic Resonance Imaging studies that showed hyper-intense signals in the axillary region. These findings define the anatomic characteristics of the thoracic interfascial plane nerve block in the axillary region, and underline the clinical potential of this novel nerve block.

    Full Text Available Demand management (DM is the process that helps companies to sell the right product to the right customer, at the right time, and for the right price. Therefore the challenge for any company is to determine how much to sell, at what price, and to which market segment while maximizing its profits. DM also helps managers efficiently allocate undifferentiated units of capacity to the available demand with the goal of maximizing revenue. This paper introduces control system approach to demand management with dynamic pricing (DP using the model predictive control (MPC technique. In addition, we present a proper dynamical system analogy based on active suspension and a stability analysis is provided via the Lyapunov direct method.

    Satellite remote sensing and GIS have emerged as the most powerful tools for inventorying, monitoring and management of natural resources and environment. In the special context of wetland ecosystems, remotely sensed data from orbital platforms have been extensively used in India for the inventory, monitoring and preparation of action plans for conservation and management. First scientific inventory of wetlands in India was carried out in 1998 by Space Applications Centre (ISRO), Ahmedabad using indigenous IRS (Indian Remote Sensing Satellite) data of 1992-93 timeframe, which stimulated extensive use of geospatial techniques for wetland conservation and management. Subsequently, with advances in GIS, studies were carried out for development of Wetland Information System for a state (West Bengal) and for Loktak lake wetland (a Ramsar site) as a prelude to National Wetland Information System. Research has also been carried out for preparation of action plans especially for Ramsar sites in the country. In a novel research, use of the geospatial technology has also been demonstrated for biodiversity conservation using landscape ecological metrics. A country-wide estimate of emission of methane, a Green House Gas, from wetlands has also been made using MODIS data. Present article critically reviews the work carried out in India for wetland conservation and management using geospatial techniques.

    The project management techniques used to manage the challenges of constructing the Gasoducto del Pacifico Pipeline from Argentina to Chile was discussed. The 543 km natural gas pipeline relied on experience of the GasAndes Pipeline Project to execute it in one year, from October 1998 to October 1999. The project management team met with success by using innovative techniques designed specifically to the following challenges: (1) fast track nature of the project, (2) contractual obligations imposed by the project management agreement between GasPacifico and TransCanada International which had the responsibility for the right-of-way acquisition, applying for regulatory approvals, design and construction of the project, (3) environmental constraints of a route through a national park in Chile and areas of high erosion and instability through the imposing Andes mountain range, (4) seasonal constraints, (5) two countries with two sets of laws and strict regulatory requirements, and (6) procurement and importation of major equipment, materials and pipe. The initial capacity of the pipeline without the addition of compression facilities was 3.7 million cubic metres per day. Total investment was in the order of $321 million US. It was emphasized that the risk associated with meeting the projects goals were minimized by critically evaluating all prospective bidders on the project. 1 ref., 7 figs.

    Full Text Available Asleep-awake-asleep technique of anesthesia is used during awake craniotomy with or without securing airway. We assessed this technique using laryngeal mask airway (LMA in two patients. Patients underwent awake craniotomy for epilepsy surgery and the removal of a frontotemporal glioma. After anesthesia induction, airway was secured using LMA. Anesthesia was maintained using oxygen, nitrous oxide and sevoflurane, supplemented with an infusion of propofol and remifentanil. Twenty minutes before corticography, anesthesia was discontinued and LMA removed. Both patients were awake and cooperative during the neurological assessment and surgery on eloquent areas. The LMA was reinserted before the closure of the dura and remained in place until the end of surgery. Both patients had no recall of events under anesthesia, although experienced mild pain and discomfort during awake phase of surgery. Both expressed complete satisfaction over the anesthetic management. Asleep-awake-asleep technique using LMA offers airway protection. The painful aspect of surgery can be performed under anesthesia, hence minimizing the duration of stress and pain. Patients remained awake and cooperative throughout the time of neurological testing.

    2016-02-01

    Cornual pregnancy is a rare form of ectopic pregnancy, accounting for up to 2% to 4% of all ectopic pregnancies, with a mortality range of 2.0% to 2.5%. Hemorrhage is a key concern in the management of such pregnancies. Traditional treatment options include a conservative approach, failing which patients are offered surgical options such as cornual resection at laparotomy, which carries a high risk of hysterectomy. In recent years newer laparoscopic cornual resection or cornuotomy techniques have been used successfully to achieve better outcomes with fewer complications. We present the double-impact devascularization (DID) technique for laparoscopic management of cornual ectopic pregnancies. This technique permits hemostatic control by compression effect, which in turn allows reduction in procedure-related patient morbidity and mortality. We also provide an overview of other reported methods of hemostatic control used in similar laparoscopic procedures. DID appears to be a useful, safe, minimally invasive technique that can be used in both laparoscopic and open surgical procedures.

    To describe a technique for the laparoscopic management of a cornual ectopic pregnancy. Step-by-step explanation of the procedure using video (Canadian Task Force classification III). Cornual pregnancy is a rare form of ectopic pregnancy, accounting for up to 2% to 4% of all ectopic pregnancies, with a mortality range of 2.0% to 2.5%, and this accounts for 20% of all deaths caused by ectopic pregnancies. Both medical and surgical treatments have been reported. Although laparotomy hysterectomy and cornuectomy used to be the preferred surgical approaches, more cornual ectopic pregnancies are being managed with the laparoscopic approach through cornuostomy or cornuectomy in recent years. The main concern with surgical treatment is hemorrhage and the need for cornual reconstruction, which necessitate advanced laparoscopic skills and technique. In this video, we describe our technique for the treatment of a cornual ectopic pregnancy. We present the case of a 21-year-old G3P2002 (gravida 3 para 2002) with the finding of a right live cornual ectopic pregnancy with gestational age of 6 weeks on pelvic ultrasound along with an elevated human chorionic gonadotropin level at 7,192 and right pelvic pain. After counseling regarding treatment options, the patient agreed with proceeding with surgery and underwent a laparoscopic right cornuectomy. Her surgery was uneventful, and she was discharged home a few hours after surgery. She was completely recovered at her postoperative follow-up visit. Her serial serum human chorionic gonadotropin levels were followed until complete resolution a few weeks later. Laparoscopic cornuectomy is a safe and effective procedure for the management of cornual ectopic pregnancy. The use of hemostatic agents and suturing can help prevent hemorrhage and allows a safe removal of the ectopic pregnancy and repair of the uterine defect created. Copyright © 2016 AAGL.

    The tremendous demands from social market are pushing the booming development of mobile communications faster than ever before, leading to plenty of new advanced techniques emerging. With the converging of mobile and wireless communications with Internet services, the boundary between mobile personal telecommunications and wireless computer networks is disappearing. Wireless networks of the next generation need the support of all the advances on new architectures, standards, and protocols. Mobility management is an important issue in the area of mobile communications, which can be best solved at the network layer. One of the key features of the next generation wireless networks is all-IP infrastructure. This paper discusses the mobility management schemes for the next generation mobile networks through extending IP's functions with mobility support. A global hierarchical framework model for the mobility management of wireless networks is presented, in which the mobility management is divided into two complementary tasks: macro mobility and micro mobility. As the macro mobility solution, a basic principle of Mobile IP is introduced, together with the optimal schemes and the advances in IPv6. The disadvantages of the Mobile IP on solving the micro mobility problem are analyzed, on the basis of which three main proposals are discussed as the micro mobility solutions for mobile communications, including Hierarchical Mobile IP (HMIP), Cellular IP, and Handoff-Aware Wireless Access Internet Infrastructure (HAWAII). A unified model is also described in which the different micro mobility solutions can coexist simultaneously in mobile networks.

    Alberta is the second largest agricultural producer in Canada, ranking just behind Ontario. Approximately 62 per cent of the province's farm cash receipts are attributable to the livestock industry. Farmers today maintain large numbers of a single animal type. The drivers for more advanced manure management systems include: the trend towards confined feeding operations (CFO) is creating large, concentrated quantities of manure; public perception of CFO; implementation of provincial legislation regulating the expansion and construction of CFO; ratification of the Kyoto Protocol raised interest in the development of improved manure management systems capable of reducing greenhouse gas (GHG) emissions; and rising energy costs. The highest methane emissions factors are found with liquid manure management systems. They contribute more than 80 per cent of the total methane emissions from livestock manure in Alberta. The author identified and analyzed three manure management techniques to mitigate GHG emissions. They were: bio-digesters, gasification systems, and composting. Three recommendations were made to establish a strategy to support emissions offsets and maximize the reduction of methane emissions from the livestock industry. The implementation of bio-digesters, especially for the swine industry, was recommended. It was suggested that a gasification pilot project for poultry manure should be pursued by Climate Change Central. Public outreach programs promoting composting of cattle manure for beef feedlots and older style dairy barns should also be established. 19 refs., 11 tabs., 3 figs.

    The postoperative period is accompanied with neuroendocrine, metabolic and immune alteration which is caused by tissue damage, anesthesia, postoperative pain and psychological stress. Postoperative pain contributes to dysfunction of immune response as a result of interaction between central nervous and immune system. The postoperatively activated hypotalamo-pituitary-adrenocortical axis, sympathic and parasympathic nerve systems are important modulators of immune response. According to bidirectional communication of immune and nervous system, appropriate postoperative pain management could affect immune response in postoperative period. Although the postoperative suppression of immune response has been reported, a very little are known about the influences of different pain management techniques on cytotoxic function of immune cells in patients with colorectal cancer in early postoperative period. Perforin is a cytotoxic molecule expressed by activated lymphocytes which has a crucial role in elimination of tumor cells and virus-infected cells, mostly during the effector's phase of immune response. Immune compromise during the postoperative period could affect the healing processes, incidence of postoperative infections and rate and size of tumor metastases disseminated during operation. The pharmacological management of postoperative pain in patients with malignancies uses very different analgesic techniques whose possible influence on cytotoxic functions of immune cells are still understood poor. For decades the most common way of treating postoperative pain after colorectal cancer surgery was intravenous analgesia with opiods. In the last decade many investigations pointed out that opiods can also contribute to postoperative suppression of immune response. Epidural analgesia is a regional anesthesia technique that acts directly on the origin of pain impulses and pain relief can be achieved with small doses of opiods combined with local anesthetics.

    Full Text Available BACKGROUND AND OBJECTIVES: In this study, the aim was to compare postoperative analgesia effects of the administration of ultrasound-guided interscalene brachial plexus block and intra-articular bupivacaine carried out with bupivacaine. METHODS: In the first group of patients 20 mL 0.25% bupivacaine and ultrasound-guided interscalene brachial plexus block (ISPB were applied, while 20 mL 0.25% bupivacaine was given via intra-articular (IA administration to the second group patients after surgery. Patients in the third group were considered the control group and no block was performed. Patient-controlled analgesia (PCA with morphine was used in all three groups for postoperative analgesia. RESULTS: In the ISPB group, morphine consumption in the periods between 0-4, 6-12 and 12-24 postoperative hours and total consumption within 24 h was lower than in the other two groups. Morphine consumption in the IA group was lower than in the control group in the period from 0 to 6 h and the same was true for total morphine consumption in 24 h. Postoperative VASr scores in the ISPB group were lower than both of the other groups in the first 2 h and lower than the control group in the 4th and 6th hours (p < 0.05. In the IA group, VASr and VASm scores in the 2nd, 4th and 6th hours were lower than in the control group (p < 0.05. CONCLUSION: Interscalene brachial plexus block was found to be more effective than intra-articular local anesthetic injection for postoperative analgesia.

    Myotonic Dystrophy (DM) affects multiple organ systems. Disorders such as hyperthyroidism, progressive musculoskeletal weakness, cardiac dysrhythmias, hypoventilation, and cognitive-behavioral disorders may be present in these patients. Thorough preoperative assessment and anesthetic planning are required to minimize the risk of anesthetic complications. Patients with DM can exhibit exquisite sensitivity to sedatives, neuromuscular blocking agents, and volatile anesthetics, resulting in potential postoperative complications. There is limited literature available on successful anesthetic techniques for the DM patient. We present this case report to add to our current fund of knowledge. PMID:28316843

    Full Text Available Aesthetic factor is an important factor in supporting the person's appearance, especially when a person smiles. Beautifull smiles form of harmonization between the teeth and gums as part of the oral cavity. One of overall aspect that has an important role in providing the overall aesthetic impression is normal gum color that pink coral. Brown or black gums are often become the complaint that interfere with appearance, especially in patients who have a habit of smoking. Pigmentation caused by melanin hyperpigmentation and usually does not present a medical problems, so patients are not aware of it. Surgical method with the scalpel scraping technique and gingivo abrasion technique using high speed carbide bur has been widely used as a method of gingival depigmentation. This method is easily done, simple and can be done in a relatively short time. In this case report presented regarding the management of patients with gingival hyperpigmentation of the maxilla and mandible were treated with surgical method using a scalpel scraping technique combined with gingivo abrasion technique using high speed carbide bur. The result, after 4 weeks follow up, color of the patient's gingival was pink and there is none recurrence of the pigmentation.

    Anesthesia for thymectomy in myasthenia gravis is challenging. Early surgical management is now considered to be an important therapeutic intervention for most of the patients of myasthenia gravis. The anesthetic experience of that technique is quite large. It involves either muscle relaxant or non-muscle relaxant techniques. However, the literature is deficient of standard anesthetic technique for thymectomy. Therefore we present in this report a modified non-muscle relaxant technique for thymectomy. We report one case with thymectomy under general anesthesia using fentanyl and propofol for induction and endotracheal intubation using non-muscle relaxant technique. The intubating, intraoperative and postoperative conditions were excellent.

    In 1996, USC switched its core two-semester software engineering course from a hypothetical-project, homework-and-exam course based on the Bloom taxonomy of educational objectives (knowledge, comprehension, application, analysis, synthesis, and evaluation). The revised course is a real-client team-project course based on the CRESST model of learning objectives (content understanding, problem solving, collaboration, communication, and self-regulation). We used the CRESST cognitive demands analysis to determine the necessary student skills required for software risk management and the other major project activities, and have been refining the approach over the last 5 years of experience, including revised versions for one-semester undergraduate and graduate project course at Columbia. This paper summarizes our experiences in evolving the risk management aspects of the project course. These have helped us mature more general techniques such as risk-driven specifications, domain-specific simplifier and complicator lists, and the schedule as an independent variable (SAIV) process model. The largely positive results in terms of review of pass / fail rates, client evaluations, product adoption rates, and hiring manager feedback are summarized as well.

    Full Text Available Context: The cost of anesthetic technique has three main components, i.e., disposable supplies, equipments, and anesthetic drugs. Drug budgets are an easily identifiable area for short-term savings. Aim: To assess and estimate the amount of anesthetic drug wastage in the general surgical operation room. Also, to analyze the financial implications to the hospital due to drug wastage and suggest appropriate steps to prevent or minimize this wastage. Settings and Design: A prospective observational study conducted in the general surgical operation room of a tertiary care hospital. Materials and Methods: Drug wastage was considered as the amount of drug left unutilized in the syringes/vials after completion of a case and any ampoule or vial broken while loading. An estimation of the cost of wasted drug was made. Results: Maximal wastage was associated with adrenaline and lignocaine (100% and 93.63%, respectively. The drugs which accounted for maximum wastage due to not being used after loading into a syringe were adrenaline (95.24%, succinylcholine (92.63%, lignocaine (92.51%, mephentermine (83.80%, and atropine (81.82%. The cost of wasted drugs for the study duration was 46.57% (Rs. 16,044.01 of the total cost of drugs issued/loaded (Rs. 34,449.44. Of this, the cost of wastage of propofol was maximum being 56.27% (Rs. 9028.16 of the total wastage cost, followed by rocuronium 17.80% (Rs. 2856, vecuronium 5.23% (Rs. 840, and neostigmine 4.12% (Rs. 661.50. Conclusions: Drug wastage and the ensuing financial loss can be significant during the anesthetic management of surgical cases. Propofol, rocuronium, vecuronium, and neostigmine are the drugs which contribute maximally to the total wastage cost. Judicious use of these and other drugs and appropriate prudent measures as suggested can effectively decrease this cost.

    We have developed techniques and software tools for efficiently managing large geosciences data sets. While the techniques were developed as part of an NSF-Funded ITR project that focuses on making NEXRAD weather data and rainfall products available to hydrologists and other scientists, they are relevant to other geosciences disciplines that deal with large data sets. Metadata, relational databases, data compression, and networking are central to our methodology. Data and derived products are stored on file servers in a compressed format. URLs to, and metadata about the data and derived products are managed in a PostgreSQL database. Virtually all access to the data and products is through this database. Geosciences data normally require a number of processing steps to transform the raw data into useful products: data quality assurance, coordinate transformations and georeferencing, applying calibration information, and many more. We have developed the concept of crawlers that manage this scientific workflow. Crawlers are unattended processes that run indefinitely, and at set intervals query the database for their next assignment. A database table functions as a roster for the crawlers. Crawlers perform well-defined tasks that are, except for perhaps sequencing, largely independent from other crawlers. Once a crawler is done with its current assignment, it updates the database roster table, and gets its next assignment by querying the database. We have developed a library that enables one to quickly add crawlers. The library provides hooks to external (i.e., C-language) compiled codes, so that developers can work and contribute independently. Processes called ingesters inject data into the system. The bulk of the data are from a real-time feed using UCAR/Unidata's IDD/LDM software. An exciting recent development is the establishment of a Unidata HYDRO feed that feeds value-added metadata over the IDD/LDM. Ingesters grab the metadata and populate the Postgre

    Local anesthetics block the transmission of painful stimuli to the brain by acting on ion channels of nociceptor fibers, and find application in the management of acute and chronic pain. Despite the key role they play in modern medicine, their cardio and neurotoxicity (together with their short half-life) stress the need for developing implantable devices for tailored local drug release, with the aim of counterbalancing their side effects and prolonging their pharmacological activity. This review discusses the evolution of the physical forms of local anesthetic delivery systems during the past decades. Depending on the use of different biocompatible materials (degradable polyesters, thermosensitive hydrogels, and liposomes and hydrogels from natural polymers) and manufacturing processes, these systems can be classified as films or micro- or nanostructured devices. We analyze and summarize the production techniques according to this classification, focusing on their relative advantages and disadvantages. The most relevant trend reported in this work highlights the effort of moving from microstructured to nanostructured systems, with the aim of reaching a scale comparable to the biological environment. Improved intracellular penetration compared to microstructured systems, indeed, provides specific drug absorption into the targeted tissue and can lead to an enhancement of its bioavailability and retention time. Nanostructured systems are realized by the modification of existing manufacturing processes (interfacial deposition and nanoprecipitation for degradable polyester particles and high- or low-temperature homogenization for liposomes) or development of novel strategies (electrospun matrices and nanogels). The high surface-to-volume ratio that characterizes nanostructured devices often leads to a burst drug release. This drawback needs to be addressed to fully exploit the advantage of the interaction between the target tissues and the drug: possible strategies

    Health and wellness represent a major global concern. Trends such as a lack of exercise and excessive consumption of calories are major causes of the rapid increase in obesity worldwide. Obesity should be controlled because it can result in other illnesses, such as diabetes, high blood pressure, high cholesterol, coronary artery disease, stroke, breathing disorders, or cancer. However, many people have difficulty in managing obesity through exercise, dietary control, behavioral modifications, and drug therapy. Bariatric surgery is not commonly used due to a variety of complications, even though it has been demonstrated to produce reliable results with respect to adequate weight loss when performed using an open or a laparoscopic approach. Endoscopic bariatric procedures are emerging techniques that are less invasive and safer compared with current surgical approaches. However, the evaluation of endoluminal procedures is limited by the small number of studies and their short-term follow-up.

    The general goal of safety management in Nuclear Power Plants (NPPs) is to make requirements and activities more risk effective and less costly. The technical specification and maintenance (TS and M) activities in a plant are associated with controlling risk or with satisfying requirements, and are candidates to be evaluated for their resource effectiveness in risk-informed applications. Accordingly, the risk-based analysis of technical specification (RBTS) is being considered in evaluating current TS. The multi-objective optimization of the TS and M requirements of a NPP based on risk and cost, gives the pareto-optimal solutions, from which the utility can pick its decision variables suiting its interest. In this paper, a multi-objective evolutionary algorithm technique has been used to make a trade-off between risk and cost both at the system level and at the plant level for loss of coolant accident (LOCA) and main steam line break (MSLB) as initiating events.

    Full Text Available It used to be hard to make your dream come true and start a business but now, thanks to the dotcom boom and the rapid development of emerging technologies everybody has the chance to become the next Steve Jobs. Quality management tools and creativity techniques gave birth to the startup trend that transforms a brilliant idea into an innovative product. A common practice amongst startups is Agile development. In this paper, after analyzing the Agile approach and the tools used to ensure quality for every stage of a product’s development life cycle and the results of using the Agile approach looking out for advantages and short comings as well, we proposed a PDCA inspired tool which embeds both quality and creativity techniques to help developers ensure quality for each stage of a product’s life cycle as well as help them better organize their activities to reach the desired goals. We validated this approach by implementing it to the case of the Vitraly startup.

  4. Translocations of amphibians: Proven management method or experimental technique

    Seigel, Richard A.; Dodd, C. Kenneth

    2002-01-01

    In an otherwise excellent review of metapopulation dynamics in amphibians, Marsh and Trenham (2001) make the following provocative statements (emphasis added): If isolation effects occur primarily in highly disturbed habitats, species translocations may be necessary to promote local and regional population persistence. Because most amphibians lack parental care, they areprime candidates for egg and larval translocations. Indeed, translocations have already proven successful for several species of amphibians. Where populations are severely isolated, translocations into extinct subpopulations may be the best strategy to promote regional population persistence. We take issue with these statements for a number of reasons. First, the authors fail to cite much of the relevant literature on species translocations in general and for amphibians in particular. Second, to those unfamiliar with current research in amphibian conservation biology, these comments might suggest that translocations are a proven management method. This is not the case, at least in most instances where translocations have been evaluated for an appropriate period of time. Finally, the authors fail to point out some of the negative aspects of species translocation as a management method. We realize that Marsh and Trenham's paper was not concerned primarily with translocations. However, because Marsh and Trenham (2001) made specific recommendations for conservation planners and managers (many of whom are not herpetologists or may not be familiar with the pertinent literature on amphibians), we believe that it is essential to point out that not all amphibian biologists are as comfortable with translocations as these authors appear to be. We especially urge caution about advocating potentially unproven techniques without a thorough review of available options.

    The effectiveness of various climate engineering techniques in limiting the global warming signal to reasonable levels has been the topic of state-of-the-art research on climate change. Using an Earth system model, we show that these techniques have the potential to bring down the high CO2 concentration climate in RCP8.5 to a moderate climate similar to RCP4.5 in terms of global temperature. Nevertheless, their influence on the regional aspects of atmospheric circulation is not clear. The regional circulation patterns in the atmosphere are largely characterized by the natural variability modes, such as the North Atlantic Oscillation (NAO). In this study, we assess the impacts of three radiation managment techniques, namely, Stratospheric Aerosol Injection (SAI), Marine Sky Brightening (MSB) and Cirrus Cloud Thinning (CCT), on the structure and features of the NAO. The results indicate an east-northeastward shift as well as intensification of the NAO spatial pattern in the global warming scenarios of RCP4.5 and RCP8.5, with the signal being most intense in the latter. The climate engineering forcings when applied to the RCP8.5 case tend to reduce the strength of the NAO with little impact on its position. The CCT case appears to have the maximum effect on the NAO signal. The patterns of cloud radiative forcing, expressed as the difference between net radiative forcing at TOA under average conditions and clear sky conditions, reveal a northeastward shift of the radiative heating in the north Atlantic region. This implies a possible link between the changes in the NAO signal and the cloud radiative forcing.

    Nitroglycerin has been used in anesthetic practice for induced hypotension and managing perioperative hypertension and myocardial ischemia. Contrary to the continuous low dose infusions (5-20 mcg/min) used for the same, intravenous bolus dosages are sometimes administered at the behest of obstetricians for removal of retained placenta. Use of nitroglycerine in managing retained placenta is undertaken as a last resort when other measures fail to relax the uterine smooth muscles. Intravenous nitroglycerine relaxes smooth muscle cells by releasing nitric oxide thus causing prompt cervico-uterine relaxation. However, administration of nitroglycerine in this manner is not without risks which should be kept in mind while using it for obstetric purposes. We hereby report a case of 22-year-old female scheduled for manual removal of placenta where unpredictable and unexpected hypoxemia was observed following nitroglycerine administration.

    As the size of typical industrial strength information systems continues to rise, particularly in the arena of Internet based management information systems and multimedia servers, the issue of managing data distribution over clusters or `farms' to overcome performance and scalability issues is becoming of paramount importance. Further, where access is global, this can cause points of geographically localized load contention to `follow the sun' during the day. Traditional site mirroring is not overly effective in addressing this contention and so a more dynamic approach is being investigated to tackle load balancing. The general objective is to manage a self-adapting, distributed database so as to reliably and consistently provide near optimal performance as perceived by client applications. Such a management system must be ultimately capable of operating over a range of time varying usage profiles and fault scenarios, incorporate considerations for communications network delays, multiple updates and maintenance operations. It must also be shown to be capable of being scaled in a practical fashion to ever larger sized networks and databases. Two key components of such an automated system are an optimiser capable of efficiently finding new configuration options, and a suitable model of the system capable of accurately reflecting the performance (or any other required quality of service metric) of the real world system. As conditions change in the real world system, these are fed into the model. The optimiser is then run to find new configurations which are tested in the model prior to implementation in the real world. The model therefore forms an evaluation function which the optimiser utilises to direct its search. Whilst it has already been shown that Genetic Algorithms can provide good solutions to this problem, there are a number of issues associated with this approach. In particular, for industrial strength applications, it must be shown that the GA employed

    The anesthesia has been improved all over the years. However, it can have impact on health, in both patients and animals anesthetized, as well as professionals exposed to inhaled anesthetics. There is continuing effort to understand the possible effects of anesthetics at molecular levels. Knowing the effects of anesthetic agents on genetic material could be a valuable basic support to better understand the possible mechanisms of these agents. Thus, the purpose of this review is to provide an overview on the genotoxic potential, evaluated in animal models, of many anesthetics that have already been used and those currently used in anesthesia.

    In recent years Air Traffic Flow Management (ATFM) has become pertinent even in regions without sustained overload conditions caused by dense traffic operations. Increasing traffic volumes in the face of constrained resources has created peak congestion at specific locations and times in many areas of the world. Increased environmental awareness and economic drivers have combined to create a resurgent interest in ATFM as evidenced by a spate of recent ATFM conferences and workshops mediated by official bodies such as ICAO, IATA, CANSO the FAA and Eurocontrol. Significant ATFM acquisitions in the last 5 years include South Africa, Australia and India. Singapore, Thailand and Korea are all expected to procure ATFM systems within a year while China is expected to develop a bespoke system. Asia-Pacific nations are particularly pro-active given the traffic growth projections for the region (by 2050 half of all air traffic will be to, from or within the Asia-Pacific region). National authorities now have access to recently published international standards to guide the development of national and regional operational concepts for ATFM, geared to Communications, Navigation, Surveillance/Air Traffic Management and Avionics (CNS+A) evolutions. This paper critically reviews the field to determine which ATFM research and development efforts hold the best promise for practical technological implementations, offering clear benefits both in terms of enhanced safety and efficiency in times of growing air traffic. An evolutionary approach is adopted starting from an ontology of current ATFM techniques and proceeding to identify the technological and regulatory evolutions required in the future CNS+A context, as the aviation industry moves forward with a clearer understanding of emerging operational needs, the geo-political realities of regional collaboration and the impending needs of global harmonisation.

  14. Surgical Tips in Frozen Abdomen Management: Application of Coliseum Technique

    Directory of Open Access Journals (Sweden)

    Ioannis D. Kyriazanos

    2015-01-01

    Full Text Available Wound dehiscence is a serious postoperative complication, with an incidence of 0.5–3% after primary closure of a laparotomy incision, and represents an acute mechanical failure of wound healing. Relatively recently the concept of “intentional open abdomen” was described and both clinical entities share common pathophysiological and clinical pathways (“postoperative open abdominal wall”. Although early reconstruction is the target, a significant proportion of patients will develop adhesions between abdominal viscera and the anterolateral abdominal wall, a condition widely recognized as “frozen abdomen,” where delayed wound closure appears as the only realistic alternative. We report our experience with a patient who presented with frozen abdomen after wound dehiscence due to surgical site infection and application of the “Coliseum technique” for its definitive surgical management. This novel technique represents an innovative alternative to abdominal exploration, for cases of “malignant” frozen abdomen due to peritoneal carcinomatosis. Lifting the edges of the surgical wound upwards and suspending them under traction by threads from a retractor positioned above the abdomen facilitates approach to the peritoneal cavity, optimizes exposure of intra-abdominal organs, and prevents operative injury to the innervation and blood supply of abdominal wall musculature, a crucial step for subsequent hernia repair.

    Objective Anti-N-methyl-D-Aspartate (NMDA) receptor encephalitis is a rare disease,recently described as autoimmune disorder of paraneoplastic limbic encephalitis,which is related to the NMDA receptor antibodies and frequently develops in young women with ovarian teratoma.The disease is usually accompanied by symptoms of psychosis and abnormal behaviors,autonomic nervous system dysfunction,central hypoventilation,and hyperthermia.During induction and maintenance of general anesthesia,we should be aware of adverse reactions such as cardiovascular events,hyperthermia and respiratory insufficiency.In order to maintain vital signs stable,pharmacological agents including vasopressors,β-blockers,antihypertensives,and anticholinergics should be prepared before the surgery.Invasive monitoring for blood pressure can be set if necessary.This study described the method for anesthetic management of 3 patients with anti-NMDA receptor encephalitis undergoing resection of ovarian teratoma under general anesthesia.Preoperative treatment included antipsychotic,anti-infective and immune therapy.General anesthesia was induced with propofol,rocuronium,fentanyl and midazolam to facilitate tracheal intubation and was maintained with inhalation of sevoflurane (mixed with oxygen and air) and intermittent iv boluses of fentanyl and rocuronium during the surgery.All the drugs mentioned above had no interaction or had slight indirect action on anti-NMDA receptors to avoid NMDA-related adverse reactions.In conclusion,the adequate preparation for the surgery should be done in this kind of patients,we should avoid using anesthetics having NMDA receptor antagonism (such as ketamine,N2O,methadone,dextromethorphan,phencyclidine) or other anesthetics acting indirectly (such as pentobarbital) on the NMDA receptors during anesthetic management in the patients with anti-NMDA receptor encephalitis.%目的 抗NMDA受体脑炎是一种与抗NMDA受体抗体相关的、自身免疫性副肿瘤边缘叶

    A 60-year-old woman posted for percutaneous nephrolithotomy with ureterolithotripsy was found to have a history of hypertension and ischemic heart disease from past 6 months on regular treatment. Pulse rate was irregularly irregular in a range of 56-60/min, unresponsive to atropine, with a sinus pause on the electrocardiogram. Although the patient was asymptomatic, anticipating unmasking of the sick sinus syndrome during general anesthesia in the prone position, a temporary pacemaker was implanted at right ventricular outflow tract (RVOT) septum before the scheduled surgery. A balanced anesthesia technique with endotracheal intubation was administered. There were several episodes of continuous pacing by the temporary pacemaker intraoperatively, which may be attributed to unmasking of the sinus node dysfunction due to general anesthesia. At the end of surgery, patient was extubated after adequate reversal from neuromuscular blockade. Postoperative period remained uneventful, and the pacemaker wires were removed on the 2(nd) postoperative day. With this case report, we highlight the importance of inserting a temporary pacemaker prior to anesthesia even in an asymptomatic patient if a sinus node dysfunction is suspected preoperatively and if intraoperative access to transvenous pacing is difficult such as in prone position. Pacing at RVOT septum minimizes ventricular dyssynchrony and improves hemodynamic parameters.

Material and methods: A pilot study with analitic design. Participating patients of Dental Emergency Service volunteers from Valdivia-Chile for mandibular teeth extractions attending between May and July of 2010. The anesthetic technique was performed by a dentist using only one cartridge of anesthetic to the NAI. After 15 minutes, the effect was considered effective when anesthetic not require reinforcement with additional anesthesia during extraction of teeth. We analyzed the relationship between success anesthetic effect with sex, age, diagnosis of tooth and type and level of pain observed (chi-square and logistic regression, p<0.05. Results: 62 patients were selected, of which only 47(75.8% was achieved anesthetic success. There was no statistical association with sex, age, type or dental diagnosis and perceived pain. Conclusion: Using a 1.8ml cartridge of anesthesia was effective in three of four patients treated by extraction of mandibular teeth. It suggests further research in relation to the clinical effectiveness of other anesthetics with the same dose in NAI.

    Placenta accreta (PA), a severe complication during delivery, is closely linked with massive hemorrhage which could endanger the lives of both mother and baby. Moreover, the incidence of PA has increased dramatically with the increasing rate of cesarean deliveries in the past few decades. Therefore, studies evaluating the effects of different perioperative managements based on different modalities in the treatment of PA are necessary. Among the numerous treatment measures, prophylactic abdominal aortic balloon occlusion (AABO) in combination with cesarean section for PA seems to be more advantageous than others. However, up to now, all studies on AABO were almost retrospective. Current evidence is insufficient to recommend for or against routinely using the AABO technology for control intraoperative hemorrhage in patients with PA. Thus, we hope to carry out a prospective, randomized controlled trial (RCT) study to confirm the effectiveness of the AABO technology in patients with PA. This trial is an investigator-initiated, prospective RCT that will test the superiority of AABO in combination with cesarean section compared to the traditional hysterectomy following cesarean section for parturients with PA. A total of 170 parturients with PA undergoing cesarean section will be randomized to receive either AABO in combination with cesarean section or the traditional hysterectomy following cesarean section. The primary outcome is estimated blood loss. The most important secondary outcome is the occurrence of cesarean hysterectomy during delivery; others include blood transfusion volume, operating time, neonate's Apgar scores (collected at 1, 5 and 10 min), length of stay in intensive care unit, total hospital stay, and balloon occlusion-relative data. This prospective trial will test the superiority of AABO in combination with cesarean section compared to the traditional hysterectomy following cesarean section for parturients with PA. It may provide strong evidence

    Thymectomy is an established therapy in the management of generalized myasthenia gravis (MG). However, the optimal surgical approach to thymectomy has remained controversial. There are advocates for transternal, transcervical approaches for "maximal" thymectomy. Video-assisted thoracoscopic thymectomy (VATT) presents new approach to thymectomy. By minimizing chest wall trauma, VATT not only causes less postoperative pain, shortens hospital stay, gives better cosmetic results but also leads to wider acceptance by patients for earlier surgery. Anesthesia for thymectomy in MG is challenging. Currently we are using non-muscle relaxant technique (NMRT) which we adopted in 1994, for maximal thymectomy. In this paper, we present our limited experience with two cases of VATT using two different NMRTs. Two cases of MG underwent VATT under general anesthesia (GA) and one lung ventilation (OLV) using double lumen tube (DLT). In both cases NMRT was used which encompass, light GA plus thoracic epidural analgesia (TEA) in one case and without TEA in the other case. We believe that the use of NMRT provides good operative and postoperative conditions. In this report we have described two different NMRTs, one with TEA and the other without. Further studies are needed on large number of cases to establish an anesthetic protocol for VATT.

    Effective project management on today's projects, where the emphasis is often on the rapid completion of the project, is not something that is learned entirely by reading a book or a report. But having the right training and the right tools makes a big difference. To be sure, even where project management is practiced professionally, the theories or the methodologies behind it are often misunderstood. As a role of management consultant, my report focus on the methods and their relationship project management use such as Earned Value Methodology, Scope Change Control, WBS (work breakdown structure) and Data Capture to plan, monitor and ultimately control projects. Thus, this report will contribute to a better understanding of how to utilize project management methods to plan and control projects so that they can be completed with constrain of time and cost. In addition, some companies in IT field for example can use computer software to manage project more effectively and efficiently.

    Cyclodextrins encapsulate and electrostatically bind to lipophilic molecules. The exterior of cyclodextrins are water-soluble and maintain aqueous solubility despite encapsulation of non-aqueous soluble molecules. This unique ability to encapsulate lipophilic molecules and maintain water solubility confers numerous pharmacologic advantages for both drug delivery and removal. Cyclodextrins, a component part of supramolecular chemistry, may be in its infancy of anesthetic application but recent advances have been described as novel and revolutionary. A review of current research coupled with an understanding of cyclodextrin properties is necessary to fully appreciate the current uses and future potentials of these unique molecules.

    Guyton, David L

    2008-01-01

    Strabismus developing after retrobulbar or peribulbar anesthesia for both anterior and posterior segment eye surgery may be due to myotoxicity to an extraocular muscle from the local anesthetic agent. Initial paresis often causes diplopia immediately after surgery, but later progressive segmental fibrosis occurs, and/or hypertrophy of the muscle, producing diplopia in the opposite direction from the direction of the initial diplopia. The inferior rectus muscle is most commonly affected. Usually a large recession on an adjustable suture of the involved muscle(s) yields good alignment. Using topical anesthesia or sub-Tenon's anesthesia can avoid this complication.

    Full Text Available Malignant hyperthermia (MH is an acute hypermetabolic crisis triggered in susceptible patients by the administration of succinylcholine or a volatile anesthetic agent. When providing anesthetic care for MH-susceptible agents, a total intravenous anesthetic (TIVA technique is frequently chosen. When choosing the components for TIVA, several options exist including the combination of propofol or dexmedetomidine with an opioid. We present our experience with the use of dexmedetomidine as a key component of the anesthetic regimen in a 5-month-old infant with a family history of MH. Previous reports of the use of dexmedetomidine in MH-susceptible patients are reviewed and its benefits in such patients discussed.

    Preoperative anxiety is a common and poorly evaluated condition in patients who will undergo an anesthetic and surgical intervention. The objective of this study was to determine the prevalence of anxiety in a group of patients undergoing elective surgery, as assessed by the Amsterdam Anxiety Preoperative and Information (AAPI) scale. We studied 135 patients scheduled for elective surgery applying the AAPI scale 24 h before the surgical procedure to evaluate the presence of anxiety and patient characteristics. A descriptive analysis with mean +/- standard deviation for categorical variables was done. For intragroup differences, chi(2) test was used. Pearson correlation for the association between anxiety and postoperative complications was carried out. A value of p =0.05 was considered significant. One hundred six patients were surgically treated, 88% were female (average age 44 +/- 12 years). Some degree of preoperative anxiety was present in 72 patients (76%; p = 0.001) with a grade point average on the AAPI scale equal to 17 +/- 7 points, of which 95 (70%, OR = 5.08; p = 0.002) were females. Results of this study suggest the presence of high levels of preoperative anxiety in patients scheduled for elective surgery. The origin of the anxiety appears to be related to many factors that can be evaluated in pre-anesthetic consultation. Further study is needed to prevent the presence of this disorder.

    2008-04-01

    An RFID-based mobile handheld inventory management system is proposed in this paper. Differing from the manual inventory management method, the proposed system works on the personal digital assistant (PDA) with an RFID reader. The system identifies electronic tags on the properties and checks the property information in the back-end database server through a ubiquitous wireless network. The system also provides a set of functions to manage the back-end inventory database and assigns different levels of access privilege according to various user categories. In the back-end database server, to prevent improper or illegal accesses, the server not only stores the inventory database and user privilege information, but also keeps track of the user activities in the server including the login and logout time and location, the records of database accessing, and every modification of the tables. Some experimental results are presented to verify the applicability of the integrated RFID-based mobile handheld inventory management system.

    Optimal pain control in patients undergoing total knee arthroplasty (TKA) is imperative for good rehabilitation and functional outcomes. However, despite technological advancements, surgeons continue to struggle with adequate pain management in their patients. Current modalities in use, such as patient-controlled analgesia, opioids, and epidural anesthetics, provide good pain relief but can be associated with side effects and serious complications. As a result, newer pain control modalities have been used to try to reduce the use of opioids while providing adequate pain relief. Currently, there are no clear guidelines or evidence for an optimum postoperative TKA analgesic regimen. Our aim was to evaluate the recent literature and provide a summary of the newer perioperative analgesic modalities. Evidence suggests that analgesics, such as newer oral medications, peripheral nerve blocks, and periarticular injections, may improve pain management, rehabilitation, and patient satisfaction, as well as reduce opioid consumption. The literature has also highlighted that a multimodal approach to pain management may provide the best results. However, determining which modalities provide superior pain control is still being extensively studied, and further research is needed.

    Mezher, T; Assem Abdul Malak, M; el-Medawar, H

    1998-01-01

    Total Quality Management (TQM) is a new management philosophy and a set of guiding principles that represent the basis of a continuously improving organization. This paper sheds light on the application of TQM concepts for software development. A fieldwork study was conducted on a Lebanese software development firm and its customers to determine the major problems affecting the organization's operation and to assess the level of adoption of TQM concepts. Detailed questionnaires were prepared and handed out to the firm's managers, programmers, and customers. The results of the study indicate many deficiencies in applying TQM concepts, especially in the areas of planning, defining customer requirements, teamwork, relationship with suppliers, and adopting standards and performance measures. One of the major consequences of these deficiencies is considerably increased programming errors and delays in delivery. Recommendations on achieving quality are discussed.

  14. Memory Compression Techniques for Network Address Management in MPI

    MPI allows applications to treat processes as a logical collection of integer ranks for each MPI communicator, while internally translating these logical ranks into actual network addresses. In current MPI implementations the management and lookup of such network addresses use memory sizes that are proportional to the number of processes in each communicator. In this paper, we propose a new mechanism, called AV-Rankmap, for managing such translation. AV-Rankmap takes advantage of logical patterns in rank-address mapping that most applications naturally tend to have, and it exploits the fact that some parts of network address structures are naturally more performance critical than others. It uses this information to compress the memory used for network address management. We demonstrate that AV-Rankmap can achieve performance similar to or better than that of other MPI implementations while using significantly less memory.

The aim of this study is to remove the salt and pepper noise which is most crucial in image processing fields. In this study, we proposed a technique which combines adaptive mean filtering technique and wavelet transform technique based on pipeline processing to remove intensity spikes from the image and then both Otsu’s and Clahe algorithms are used to enhance the image. The implemented framework produces good results and proves against salt and pepper noise using PSNR algorithm.

    Full Text Available There is no doubt that strategic management tools and techniques are important parts of the strategic management process. Their use in organizations should be observed in a practice-based context. This paper analyzes the empirical studies on the usage of strategic management tools and techniques. Hence, the main aim of this study is to investigate and analyze which enterprises, according to their country development level, use more strategic management tools and techniques and which of these are used the most. Also, this paper investigates which strategic management tools and techniques are used globally according to the results of empirical studies. The study presents a summary of empirical studies for the period 1990–2015. The research results indicate that more strategic tools and techniques are used in developed countries, followed by developing countries and fewest in countries in transition. This study is likely to contribute to the field of strategic management because it summarizes the most used strategic tools and techniques at the global level according to varying stages of countries’ economic development. Also, the findings from this study may be utilized to maximize the full potential of enterprises and reduce the cases of entrepreneurship failures, through creating awareness of the importance of using strategic management tools and techniques.

    Gayathri, Prabakaran; Pandey, Ramesh Kumar; Jain, Eesha

    2014-01-28

    Internal inflammatory root resorption is characterised by progressive destruction of intraradicular dentin and dentinal tubules along the root canal wall. A number of theories have been proposed as a possible cause for internal resorption. It is usually asymptomatic and detected during routine radiographic investigations. Prompt diagnosis and early management of such defects is essential to maintain the integrity of the tooth. Non-surgical and surgical methods are the two main strategies involved in the management of internal resorption. The non-surgical method is usually preferred, but in cases of extensive resorption with external root perforation, surgical intervention has been advocated. The present case illustrates repair of perforating internal resorption by hybrid method, using mineral trioxide aggregate and gutta-percha, following surgical exposure. After a 10-month follow-up, no clinical and radiographic abnormalities were observed. Additionally, there was also marked reduction in periodontal pocket depth.

    2002-06-01

    This paper discusses the contribution offered by radiological techniques to the diagnosis of the medical and surgical complications of anorexia nervosa (AN) and bulimia (BN) with the aim of providing general indications as to their use and suggesting the best-suited techniques. In the broad field of the complications of malnourishment, the use of magnetic resonance (MR) instead of computed tomography (CT) in the assessment of brain atrophy provides much more information at a better cost-benefit ratio. Like brain atrophy, other complications may be chance radiographic findings, such as cathartic colon and colon ptosis. Pulmonary tuberculosis and the presence of bronchopneumonia in conditions of malnutrition demand that conventional X-rays be supplemented by high-resolution CT scans, MR and echotomography. When checking for parotidomegaly and polycystic ovary, the best imaging technique is echotomography. Radiologists are also called upon to express their view in the case of emergencies such as the rupture of the esophagus and osteoporosis-induced fractures.

    2006-02-01

    Full Text Available Doxepin, a tricyclic antidepressant, was recently found to be effective in the treatment of various acute and chronic painful conditions. However, the mechanism of its actions was not clear, especially when involving the spine. The aim of our study was to evaluate the spinal anesthetic effect of doxepin. Two commonly used traditional local anesthetics, bupivacaine and lidocaine, were used as controls. The potencies and durations of the drugs' action were evaluated in male Sprague-Dawley rats. We found that intrathecally administered doxepin, like bupivacaine and lidocaine, produced dose-related spinal anesthetic effects on motor activity, proprioception, and nociception. Among the three drugs, doxepin produced spinal anesthetic effects in rats more potent than that of lidocaine (p < 0.001, in each comparison and longer than that of bupivacaine and lidocaine (p < 0.001, in each comparison. The spinal activity of doxepin may provide some explanation of its clinical effect in pain management.

    The objective in traditional scheduling is usually time based. Minimizing the makespan, total flow times, total tardi costs, etc. are instances of these objectives. In manufacturing, processing each job entails a cost paying and price receiving. Thus, the objective should include some notion of managing the flow of cash. We have defined two new objectives: maximization of average and minimum available cash. For single machine scheduling, it is demonstrated that scheduling jobs in decreasing order of profit ratios maximizes the former and improves productivity. Moreover, scheduling jobs in increasing order of costs and breaking ties in decreasing order of prices maximizes the latter and creates protection against financial instability.

    2014-11-01

    We aimed to present blepharoplasty techniques we used for severe orbito-temporal neurofibromatosis (NF). A retrospective noncomparative single-center case study was undertaken on patients with orbito-temporal NF. Twenty-two patients with orbito-temporal NF treated at the Department of Ophthalmology of Shanghai Ninth People's Hospital between 2007 and 2011 participated in the study. They underwent a standard ophthalmologic assessment for orbito-temporal NF involving both the orbito-temporal soft tissue and bony orbits. The orbits were examined with three-dimensional computed tomography (CT) and all 22 patients underwent tumor debulking, blepharoplasty, and orbital reconstruction. We modified the conventional procedures. Our reconstructive techniques included eyelid reduction; lateral canthal reattachment; for patients with collapse of the lateral orbital margin, reconstruction of the orbital margin to be performed before reattaching the lateral canthus to the implanted titanium mesh; anterior levator resection; and frontalis suspension according to preoperative levator muscle function. Visual acuity, tumor recurrence, and postoperative palpebral fissure and orbital appearance were evaluated to assess outcomes. Acceptable cosmetic results were obtained in 22 patients after debulking of the orbito-temporal NF and surgical reconstruction. There was no loss of vision or visual impairment postoperatively. All patients did not display recrudescence after a follow-up period of >1 year. Three patients with residual ptosis were successfully treated with a second ptosis repair. We believe that the blepharoplasty techniques described in the treatment of orbito-palpebral NF may provide both functional and esthetic benefits.

    Recent advances in precision agriculture technologies and spatial statistics allow realistic, site-specific estimation of nematode damage to field crops and provide a platform for the site-specific delivery of nematicides within individual fields. This paper reviews the spatial statistical techniques that model correlations among neighboring observations and develop a spatial economic analysis to determine the potential of site-specific nematicide application. The spatial econometric methodology applied in the context of site-specific crop yield response contributes to closing the gap between data analysis and realistic site-specific nematicide recommendations and helps to provide a practical method of site-specifically controlling nematodes.

    To collect data in the current literature dealing with the diffusion, the reliability and the effectiveness of the rectal administration of anaesthetic drugs. To evaluate differences with parenteral administration. Pharmacokinetics and clinical studies published in recent years in indexed journals. Based on the study methodology, drugs employed and pharmacokinetic parameters evaluated. Factors involved in absorption of drugs from the rectal mucosa, clinical effect and pharmacokinetic data of the following drugs: diazepam, flunitrazepam, midazolam, ketamin and methohexital, then a brief evaluation of other drugs: thiopental, etomidate, morphine and chloral hydrate. The most widely used drugs are benzodiazepines: they are safe, easy to manage and highly effective; among them midazolam has the best kinetic and dynamic pattern. Ketamin is useful during painful diagnostic procedures; with the use of barbiturates there is a greater risk of respiratory depression and more caution must be employed. Wide intervariability of rate of absorption, achievement of plasma levels and clinical effect is a relevant drawback of this technique, such to make it not preferable to the parenteral route, when both are feasible. It deserves, anyway, more consideration, and maintains its validity for the preparation of the paediatric patient to general anaesthesia.

    2016-12-01

    The iliopsoas tendon is an important dynamic stabilizer of the hip joint, and it should be carefully identified and preserved during routine hip arthroscopy. However, it may also be a source of hip pain manifesting as iliopsoas tendinitis or a snapping hip or contributing to the development of labral pathology caused by psoas impingement. In the appropriately indicated, refractory cases of iliopsoas-related hip pain, surgical intervention in the form of an iliopsoas tenotomy at the level of the labrum can result in reliable pain relief. We describe a method to identify and protect the iliopsoas tendon during routine hip arthroscopy when preservation is desired. In addition, we detail how to deepen the psoas tunnel if psoas impingement is present but psoas tenotomy is contraindicated. We also describe a reproducible technique of arthroscopic iliopsoas tenotomy using standard portals and minimal equipment when indicated.

  14. SYSTEMIC TOXIC REACTIONS TO LOCAL ANESTHETICS

    Science.gov (United States)

    Moore, Daniel C.; Green, John

    1956-01-01

    The topical use of anesthetic agents involves an element of risk. Systemic toxic reactions are rare, but they do occur and may result in death. When a reaction occurs from a topical application, it usually progresses rapidly to respiratory and cardiovascular collapse, and thus therapy must be instituted with more haste to avoid deaths. Fatal systemic toxic reactions from topically administered anesthetic drugs are, in effect, usually not due to well informed use of the drug but to misuse owing to less than complete understanding of absorption. Emphasis is placed on the causes, prophylaxis and treatment of severe systemic toxic reactions which follow the topical application of local anesthetic drugs. If systemic toxic reactions resulting from a safe dose of a local anesthetic agent are correctly treated, there will usually follow an uneventful recovery rather than a catastrophe. PMID:13343009

  15. First Approximations of Prescribed Fire Risks Relative to Other Management Techniques Used on Private Lands.

    Directory of Open Access Journals (Sweden)

    Dirac Twidwell

    Full Text Available Fire is widely recognized as a critical ecological and evolutionary driver that needs to be at the forefront of land management actions if conservation targets are to be met. However, the prevailing view is that prescribed fire is riskier than other land management techniques. Perceived risks associated with the application of fire limits its use and reduces agency support for prescribed burning in the private sector. As a result, considerably less cost-share support is given for prescribed fire compared to mechanical techniques. This study tests the general perception that fire is a riskier technique relative to other land management options. Due to the lack of data available to directly test this notion, we use a combination of approaches including 1 a comparison of fatalities resulting from different occupations that are proxies for techniques employed in land management, 2 a comparison of fatalities resulting from wildland fire versus prescribed fire, and 3 an exploration of causal factors responsible for wildland fire-related fatalities. This approach establishes a first approximation of the relative risk of fatality to private citizens using prescribed fire compared to other management techniques that are readily used in ecosystem management. Our data do not support using risks of landowner fatalities as justification for the use of alternative land management techniques, such as mechanical (machine-related equipment, over prescribed fire. Vehicles and heavy machinery are consistently leading reasons for fatalities within occupations selected as proxies for management techniques employed by ranchers and agricultural producers, and also constitute a large proportion of fatalities among firefighters. Our study provides the foundation for agencies to establish data-driven decisions regarding the degree of support they provide for prescribed burning on private lands.

    Full Text Available Fibrous dysplasia is a pathologic condition of bone of unknown etiology with no apparent familial, hereditary or congenital basis. Lichtenstein first coined the term in 1938 and in 1942 he and Jaffe separated it from other fibro-osseous lesions. It is a bone tumor that, although benign, has the potential to cause significant cosmetic and functional disturbance, particularly in the craniofacial skeleton. Its management poses significant challenges to the surgeon. Craniofacial fibrous dysplasia is 1 of 3 types of fibrous dysplasia that can affect the bones of the craniofacial complex, including the mandible and maxilla. Fibrous dysplasia is a skeletal developmental disorder of the bone-forming mesenchyme that manifests as a defect in osteoblastic differentiation and maturation. It is a lesion of unknown etiology, uncertain pathogenesis, and diverse histopathology. Fibrous dysplasia represents about 2, 5% of all bone tumors and over 7% of all benign tumours. Over the years, we have gained a better understanding of its etiology, clinical behavior, and both surgical and non-surgical treatments.

    An interdisciplinary team should be involved in the diagnosis and management of severely injured patients. The adoption of criteria for starting treatment for multiple trauma avoids underestimation of seriousness of injury. These criteria are established by the circumstances of the accident, the patterns of trauma, and the vital findings. Basic diagnosis comprises a limited number of plain films in the trauma room, including supine chest, lateral cervical spine, and pelvis, and ultrasound of abdomen, pleura, and pericardium. Organ diagnosis using CT is complementary and depends on the clinical findings and findings from the basic investigations. We recommend spiral CT (skull base 2/2/4 mm, cerebrum 8/8/8 mm native) and after intravenous contrast medium thoracic (5/7.5/5 mm) and abdominal CT (8/12/8 mm). Image reconstruction of bony structures can be added. The CT and the trauma center should be in close proximity; time-consuming transfers must be avoided. If this is not possible, a CT can be integrated in the trauma room. Our hospital trauma registry contains over 2200 entries. A quality committee has been established and external quality control is implemented. (orig.)

    Full Text Available In 2020 more than50 billions devices will be connected over the Internet. Every device will be connected to anything, anyone, anytime and anywhere in the world of Internet of Thing or IoT. This network will generate tremendous unstructured or semi structured data that should be shared between different devices/machines for advanced and automated service delivery in the benefits of the user’s daily life. Thus, mechanisms for data interoperability and automatic service discovery and delivery should be offered. Although many approaches have been suggested in the state of art, none of these researches provide a fully interoperable, light, flexible and modular Sensing/Actuating as service architecture. Therefore, this paper introduces a new Semantic Multi Agent architecture named OntoSmart for IoT data and service management through service oriented paradigm. It proposes sensors/actuators and scenarios independent flexible context aware and distributed architecture for IoT systems, in particular smart home systems.

    Full Text Available This research shows a case from Jordan where geospatial techniques were utilized for irrigation water auditing. The work was based on assessing records of groundwater abstraction in relation to irrigated areas and estimated crop water consumption in three water basins: Yarmouk, Amman-Zarqa and Azraq. Mapping of irrigated areas and crop water requirements was carried out using remote sensing data of Landsat 8 and daily weather records. The methodology was based on visual interpretation and the unsupervised classification for remote sensing data, supported by ground surveys. Net (NCWR and gross (GCWR crop water requirements were calculated by merging crop evapotranspiration (ETc, calculated from daily weather records, with maps of irrigated crops. Gross water requirements were compared with groundwater abstractions recorded at a farm level to assess the levels of abstraction in relation to groundwater safe yield. Results showed that irrigated area and GCWR were higher than officially recorded cropped area and abstracted groundwater. The over abstraction of groundwater was estimated to range from 144% to 360% of the safe yield in the three basins. Overlaying the maps of irrigation and groundwater wells enabled the Ministry of Water and Irrigation (MWI to detect and uncover violations and illegal practices of irrigation, in the form of unlicensed wells, incorrect metering of pumped water and water conveyance for long distances. Results from the work were utilized at s high level of decision-making and changes to the water law were made, with remote sensing data being accredited for monitoring water resources in Jordan.

    As with any technological innovation, time refines the technology, improving upon the original version of the innovative product. The initial GM crops had single traits for either herbicide tolerance or insect resistance. Current varieties have both of these traits stacked together and in many cases other abiotic and biotic traits have also been stacked. This innovation requires investment. While this is relatively straight forward, certain conditions need to exist such that investments can be facilitated. The principle requirement for investment is that regulatory frameworks render consistent and timely decisions. If the certainty of regulatory outcomes weakens, the potential for changes in investment patterns increases.   This article provides a summary background to the leading plant breeding technologies that are either currently being used to develop new crop varieties or are in the pipeline to be applied to plant breeding within the next few years. Challenges for existing regulatory systems are highlighted. Utilizing an option value approach from investment literature, an assessment of uncertainty regarding the regulatory approval for these varying techniques is undertaken. This research highlights which technology development options have the greatest degree of uncertainty and hence, which ones might be expected to see an investment decline.

    The authors compared the incidence of respiratory complications and arterial hemoglobin desaturation during emergence from anesthesia in children whose tracheas were extubated while they were anesthetized or after they were awake and to whom halothane or isoflurane had been administered. One hundred children 1-4 yr of age undergoing minor urologic surgery were studied. After a standard induction technique, patients were randomized to receive either isoflurane or halothane. In 50 patients tracheal extubation was performed while they were breathing 2 MAC of either halothane or isoflurane in 100% oxygen. The remaining 50 patients received 2 MAC (volatile agent plus nitrous oxide) during the operation, but tracheal extubation was delayed until they were awake. A blinded observer recorded the incidence of respiratory complications and continuously measured hemoglobin saturation for 15 min after extubation. When tracheal extubation occurred in deeply anesthetized patients, no differences were found between the two volatile agents. When tracheal extubation of awake patients was performed, the use of isoflurane was associated with more episodes of coughing and airway obstruction than was halothane (P less than 0.05). Awake tracheal extubation following either agent was associated with significantly more episodes of hemoglobin desaturation than was tracheal extubation while anesthetized.

  3. Interactions of some local anesthetics and alcohols with membranes.

    2001-09-01

    A review of the results obtained by our group in the last decade regarding the interactions of procaine, lidocaine, dibucaine and tetracaine with membranes is presented in the context of the literature data. The action upon membranes, in first approximation monomolecular film of stearic acid spread at the air/water interface used as a membrane model, the modification of biomembrane structure and function using diffraction methods, lipid phase transition, fluidity of lipids and proteins, membrane expansion and platelet aggregation were studied. The thermodynamic knowledge of membrane-alcohol interactions improved by using highly sensitive calorimetric techniques are briefly reported. One of the main conclusions is that the physical state of a monolayer model membrane was the result of competitive interactions between film-film and film-substrate interactions. It was taken into account that local anesthetics, such as lidocaine, carbisocaine, mesocaine, showed changes in the bilayer structure, reflected in macroscopic mechanical properties. This restructuring of the lipid bilayer has a significant influence on the operation of functional subunits, e.g. ionic channels formed by gramicidin. The results support the concept of non-specific interactions of local anesthetics with lipid bilayers. The theoretical modeling of the interactions of local anesthetics is closely compared with experimental data. Our new theory of relaxation for these interactions is using a non-archimedean formalism based on a process resulting from superpositions of different component processes which take place at different scales of time.

This visit enables the anesthetist to know about the patient's general health status and the nature of surgery, to choose the type of anesthesia, and to discuss perioperative complications and their management with the patient. Patients have sometimes complained about the information given during the preoperative anesthetic evaluation in the University of Gondar teaching and referral hospital. The aim of this study was to determine the level of patient satisfaction with the preoperative anesthetist visit. Methods: A cross-sectional study was conducted from February 15 to April 15, 2013. All consecutive elective patients who were operated upon under anesthesia during the study period were interviewed 24 hours after operation. A pretested questionnaire and checklists, which were developed based on the hospital's anesthetic evaluation sheet, were used for data collection. Results: A total of 116 elective patients were operated upon under anesthesia during the study period. Of these, 102 patients were included in our study, with a response rate of 87.9%. Anesthetists introduced themselves to ~24% patients; provided information about anesthesia to ~32%, postoperative complications to ~21%, postoperative analgesia to ~18, and postoperative nausea and vomiting to ~21%; and spent adequate time with ~74%. Patients' questions were answered by the anesthetist in ~65% of cases, and ~65% of patients had reduced anxiety after the anesthetist visit. The patients' overall satisfaction with the preoperative anesthetist visit was ~65%. Conclusion and recommendation: Patient satisfaction with the

    Full Text Available The comparison of throughput for TEAR (TCP emulation at receivers and TFRC TCP friendly rate control in MANETs is done with varying Active queue Management Techniques. The analysis reveals that for bandwidth constraint links, TEAR and TFRC perform far better than normal traffic propagation through TCP. In case of TEAR, the processing and route congestion algorithm load is shared by the receiver resulting in lesser load at the transmitters. In TFRC the TCP traffic is propagated via an algorithm to curb acknowledgement congestions. The effect of these two techniques is monitored on Droptail and RED, two of the most common Active Queue Management Techniques.

    2013-04-01

    This article details a self-hypnosis technique designed to teach patients how to manage acute or chronic pain through directed focus. The focused suggestion with somatic anchoring technique has been used with various types of pain, including somatic pain (arthritis, post-injury pain from bone breaks, or muscle tears), visceral pain (related to irritable bowel disease), and neuropathic pain (related to multiple sclerosis). This technique combines cognitive restructuring and mindfulness meditation with indirect and direct suggestions during hypnosis. The case examples demonstrate how the focused suggestion with somatic anchoring technique is used with both acute and chronic pain conditions when use of long-term medication has been relatively ineffective.

    In this article, we have proposed a blind, fragile and Region of Interest (ROI) lossless medical image watermarking (MIW) technique, providing an all-in-one solution tool to various medical data distribution and management issues like security, content authentication, safe archiving, controlled access retrieval, and captioning. The proposed scheme combines lossless data compression and encryption technique to embed electronic health record (EHR)/DICOM metadata, image hash, indexing keyword, doctor identification code and tamper localization information in the medical images. Extensive experiments (both subjective and objective) were carried out to evaluate performance of the proposed MIW technique. The findings offer suggestive evidence that the proposed MIW scheme is an effective all-in-one solution tool to various issues of medical information management domain. Moreover, given its relative simplicity, the proposed scheme can be applied to the medical images to serve in many medical applications concerned with privacy protection, safety, and management.

    1975-01-01

    Laboratory screening of a series of halogenated methyl isopropyl ethers revealed sevoflurane (fluoromethyl-1,1,1,3,3,3,-hexafluroro-2-propyl ether) as a potent nonexplosive inhalational anesthetic agent. Sevoflurance, a pleasant-smelling liquid, boils at 58.5 degrees C at 760 torr and has a vapor pressure of 200 torr at 25 degrees C. It is nonflammable in air and has lower flammability limits of 11 vols percent in O2 and 10 vols percent in N2O. Sevoflurane exhibits limited chemical reactivity in vitro; it is subject to slight but measurable hydrolysis, and reacts with soda lime to form traces of related ethers. It provides rapid anesthetic induction and recovery consistent with its low distribution coefficients (blood:gas, 0.6; corn oil:gas, 41.6; olive oil:gas, 53.4). In dogs, anesthetic concentrations of sevoflurane did not produce spontaneous cardiac arrhythmias and did not sensitize the heart to epinephrine. Electroencephalographic patterns were similar to those observed during anesthesia with halothane. In rats, small increases in the urinary excretion of inorganic fluoride ion occurred during the first 24 hours after anesthesia. Subacute studies in dogs and rats, using closed-circle absorption with soda lime, revealed no toxicologically significant changes in animals anesthetized frequently for 2 weeks. Sevoflurane appears to be a unique volatile anesthetic agent worthy of further study.

    The construction process of detectors for the Large Hadron Collider (LHC) experiments is large scale, heavily constrained by resource availability and evolves with time. As a consequence, changes in detector component design need to be tracked and quickly reflected in the construction process. With similar problems in industry engineers employ so-called Product Data Management (PDM) systems to control access to documented versions of designs and managers employ so- called Workflow Management software (WfMS) to coordinate production work processes. However, PDM and WfMS software are not generally integrated in industry. The scale of LHC experiments, like CMS, demands that industrial production techniques be applied in detector construction. This paper outlines the major functions and applications of the CRISTAL system (Cooperating Repositories and an information System for Tracking Assembly Lifecycles) in use in CMS which successfully integrates PDM and WfMS techniques in managing large scale physics detector ...

Aim: The purpose of the study was to evaluate the anesthetic efficacy of X-tip intraosseous injection in patients with symptomatic irreversible pulpitis, in mandibular posterior teeth, using 4% Articaine with 1:100,000 adrenaline as local anesthetic, when the conventional inferior alveolar nerve block proved ineffective. Materials and Methods: X-tip system was used to administer 1.7 ml of 4% articaine with 1:100,000 adrenaline in 30 patients diagnosed with irreversible pulpitis of mandibular posterior teeth with moderate to severe pain on endodontic access after administration of an inferior alveolar nerve block. Results: The results of the study showed that 25 X-tip injections (83.33% were successful and 5 X-tip injections (16.66% were unsuccessful. Conclusion: When the inferior alveolar nerve block fails to provide adequate pulpal anesthesia, X-tip system using 4% articaine with 1:100,000 adrenaline was successful in achieving pulpal anesthesia in patients with irreversible pulpitis.

    Full Text Available INTRODUCTION: Optimum treatment for postoperative pain has been of fundamental importance in surgical patient care. Among the analgesic techniques aimed at this group of patients, thoracic paravertebral block combined with general anesthesia stands out for the good results and favorable risk-benefit ratio. Many local anesthetics and other adjuvant drugs are being investigated for use in this technique, in order to improve the quality of analgesia and reduce adverse effects. OBJECTIVE: Evaluate the effectiveness and safety of paravertebral block compared to other analgesic and anesthetic regimens in women undergoing breast cancer surgeries. METHODS: Integrative literature review from 1966 to 2012, using specific terms in computerized databases of articles investigating the clinical characteristics, adverse effects, and beneficial effects of thoracic paravertebral block. RESULTS: On the selected date, 16 randomized studies that met the selection criteria established for this literature review were identified. Thoracic paravertebral block showed a significant reduction of postoperative pain, as well as decreased pain during arm movement after surgery. CONCLUSION: Thoracic paravertebral block reduced postoperative analgesic requirement compared to placebo group, markedly within the first 24 h. The use of this technique could ensure postoperative analgesia of clinical relevance. Further studies with larger populations are necessary, as paravertebral block seems to be promising for preemptive analgesia in breast cancer surgery.

    Full Text Available Background : Anxiety and fear remain the primary emotion of a child entering a dental office. Successful pediatric dentistry depends not only on the dentist′s technical skills, but also on his ability to acquire and maintain a child′s cooperation. Methods: A retrospective study was done using the case records of 247 children, to evaluate their behavior patterns, based on the Wright′s modification of Frankl′s behavior rating scale. Various behavior management techniques like the tell-show-do, reinforcements, voice control, and hand over mouth exercise used in the postgraduate section of the Department of Pediatric Dentistry, Meenakshi Ammal Dental College, Chennai, India, were also evaluated in this study. Results: Behavior of the children improved on the subsequent visits. Tell-show-do was the most common behavior management technique used and more aversive management techniques were rarely used in managing children in the dental office. Conclusion: Proper assessment of children′s behavior helps the dentist to plan appointments and render effective and efficient dental treatment. Appropriate use of management techniques can improve the child′s behavior in subsequent dental visits.

    Full Text Available The knowledge about methods and techniques of quality management together with their effective use can be definitely regarded as an indication of high organisational culture. Using such methods and techniques in an effective way can be attributed to certain level of maturity, as far as the quality management system in an organisation is concerned. There is in the paper an analysis of problem-solving methods and techniques of quality management in the automotive sector in Poland. The survey was given to the general population, which in case of the study consisted of companies operating in Poland that had certified quality management systems against ISO/TS 16949. The results of the conducted survey and the conclusions of the author can show actual and potential OEM suppliers (both 1st and 2nd tier in which direction their strategies for development and improvement of quality management systems should go in order to be effective. When the universal character of methods and techniques used in the surveyed population of companies is taken into consideration, it can be assumed that the results of the survey are also universal for all organisations realising the TQM strategy. The results of the research confirmed that methods which are also the basis for creating key system documents are the most relevant ones, i.e. flowcharts and FMEA, and moreover process monitoring tools (SPC and problem solving methods -above all 8D.

    The purpose of the study was to identify the level of knowledge of local anesthetics frequently used in the surgical clinic by third and fourth year dental students in daily practice. The importance of pharmacology in dental practice in underscored by potential drug toxicity. The study was performed with 244 third and fourth grade career dental students (CDS). Eleven items regarding the knowledge over local anesthetics at the clinic; i.e., the appropriate doses, possible toxic effects and side effects were examined. The reference questionnaire which is in a validation process, is a way to evaluate student knowledge about most drugs used in odontology practice such as: NSAIDs, antibiotics and local anesthetics. The results were found to be unsatisfactory with a high percentage of students failing (less than six of eleven items correct). We conclude that determination of practice knowledge is an essential step in informing the institution about cognitive deficiencies identified in order to plan learning solutions.

    Wrong-site surgery in dermatology often occurs due to difficulty finding the initial biopsy site prior to Mohs surgery. Patients frequently present for Mohs surgery weeks to months following the initial biopsy site. Visualization of the biopsy site may become difficult at presentation due to healing. To investigate the utility of anesthetic blister induction at a suspected biopsy site to identify the location prior to Mohs surgery. The proposed technique is visualization of a blister that is induced by local anesthetic administration at the proposed biopsy site. The addition of this technique among others such as curettage, dermoscopy, and UV fluorescence can prevent wrong-site surgery. A biopsy site of a squamous cell carcinoma on a patient was compared via photography for visibility at the time of initial biopsy, weeks following biopsy, and post-anesthetic blister induction. The biopsy site was easier to locate with the assistance of a blister that formed as a result of local anesthetic administration. Blister induction by local anesthetic administration can assist in accurately identifying healed or obscured biopsy sites.

    2000-08-01

    We investigated the hyperalgesic (antianalgesic) effect of the inhaled anesthetics isoflurane, halothane, nitrous oxide, and diethyl ether, or the nonimmobilizer 1, 2-dichlorohexafluorocyclobutane at subanesthetic partial pressures (or, for the nonimmobilizer, subanesthetic partial pressures predicted from lipid solubility) in rats. Hyperalgesia was assessed as a decrease in the time to withdrawal of a rat hind paw exposed to heat. All four anesthetics, including nitrous oxide and diethyl ether, produced hyperalgesia at low partial pressures, with a maximal effect at 0.1 minimum alveolar anesthetic concentration (MAC) required to prevent response to movement in 50% of animals, and analgesia (an increased time to withdrawal of the hind paw) at 0. 4 to 0.8 MAC. The nonimmobilizer had neither analgesic nor hyperalgesia effects. We propose that inhaled anesthetics with a higher MAC-Awake (the MAC-fraction that suppresses appropriate responsiveness to command), such as nitrous oxide and diethyl ether, can be used as analgesics because patients are conscious at higher anesthetic partial pressures, including those which have analgesic effects, whereas anesthetics with a lower MAC-Awake do not produce analgesic effects at concentrations that permit consciousness. The inhaled anesthetics isoflurane, halothane, nitrous oxide, and diethyl ether produce antianalgesia at subanesthetic concentrations, with a maximal effect at approximately one-tenth the concentration required for anesthesia. This effect may enhance perception of pain when such small concentrations are reached during recovery from anesthesia.

    Sepsis remains to be a significant health care issue associated with high mortality and healthcare cost, despite the extensive effort to better understand the pathophysiology of the sepsis. Recently updated clinical guideline for severe sepsis and septic shock, "Surviving Sepsis Campaign 2012", emphasizes the importance of early goal-directed therapy, which can be implemented in intraoperative management of sepsis patients. Herein, we review the updates of current guideline and discuss its application to anesthesic management. Furthermore, we review the recent advance in knowledge of sepsis pathophysiology, focusing on immune modulation, which may lead to new clinical therapeutic approach to sepsis.

    Chordee with or without hypospadias is usually managed successfully in a fairly straightforward manner. However, on occasion there are patients with severe chordee that cannot be corrected with the standard techniques. In this setting tunica vaginalis grafts, dermal grafts and Nesbit plication techniques have been used but all of these procedures have major drawbacks. During the last 5 years we have used an alternative technique for the correction of severe ventral curvature that persists despite complete resection of fibrous chordee. This technique combines a deep vertical incision between the corporeal bodies ventrally with a series of transverse dorsal plicating sutures to correct chordee. There is no incision into the corporeal bodies and no shortening of the penis as with the Nesbit technique, and potential injury to the neurovascular bundles is minimized. Followup 1 to 5 years later in 6 patients confirms satisfactory chordee correction in all cases.

    2015-01-01

    Full Text Available In MANET multicasting, forward and backward secrecy result in increased packet drop rate owing to mobility. Frequent rekeying causes large message overhead which increases energy consumption and end-to-end delay. Particularly, the prevailing group key management techniques cause frequent mobility and disconnections. So there is a need to design a multicast key management technique to overcome these problems. In this paper, we propose the mobility based key management technique for multicast security in MANET. Initially, the nodes are categorized according to their stability index which is estimated based on the link availability and mobility. A multicast tree is constructed such that for every weak node, there is a strong parent node. A session key-based encryption technique is utilized to transmit a multicast data. The rekeying process is performed periodically by the initiator node. The rekeying interval is fixed depending on the node category so that this technique greatly minimizes the rekeying overhead. By simulation results, we show that our proposed approach reduces the packet drop rate and improves the data confidentiality.

    Progress is reported in formulating energy management strategies for stand-alone PV systems, developing an analytical tool that can be used to investigate these strategies, applying this tool to determine the proper control algorithms and control variables (controller inputs and outputs) for a range of applications, and quantifying the relative performance and economics when compared to systems that do not apply energy management. The analysis technique developed may be broadly applied to a variety of systems to determine the most appropriate energy management strategies, control variables and algorithms. The only inputs required are statistical distributions for stochastic energy inputs and outputs of the system and the system's device characteristics (efficiency and ratings). Although the formulation was originally driven by stand-alone PV system needs, the techniques are also applicable to hybrid and grid connected systems.

    The need for economic analysis for the design and implementation of efficient water resources management policies is well documented in the economics literature. This need is also emphasised in the European Union's recent Water Framework Directive (2000/60/EC), and is relevant to the objectives of Euro-limpacs, an EU funded project which inter alia, aims to provide a decision-support system for valuing the effects of future global change on Europe's freshwater ecosystems. The purpose of this paper is to define the role of economic valuation techniques in assisting in the design of efficient, equitable and sustainable policies for water resources management in the face of environmental problems such as pollution, intensive land use in agriculture and climate change. The paper begins with a discussion of the conceptual economic framework that can be used to inform water policy-making. An inventory of the available economic valuation methods is presented and the scope and suitability of each for studying various aspects of water resources are critically discussed. Recent studies that apply these methods to water resources are reviewed. Finally, an application of one of the economic valuation methods, namely the contingent valuation method, is presented using a case study of the Cheimaditida wetland in Greece.

    Chronic stress has been shown to be associated with disease. This link is not only direct but also indirect through harmful health behavior such as smoking or changing eating habits. The recent mHealth trend offers a new and promising approach to support the adoption and maintenance of appropriate stress management techniques. However, only few studies have dealt with the inclusion of evidence-based content within stress management apps for mobile phones. The aim of this study was to evaluate stress management apps on the basis of a new taxonomy of effective emotion-focused stress management techniques and an established taxonomy of behavior change techniques. Two trained and independent raters evaluated 62 free apps found in Google Play with regard to 26 behavior change and 15 emotion-focused stress management techniques in October 2015. The apps included an average of 4.3 behavior change techniques (SD 4.2) and 2.8 emotion-focused stress management techniques (SD 2.6). The behavior change technique score and stress management technique score were highly correlated (r=.82, P=.01). The broad variation of different stress management strategies found in this sample of apps goes in line with those found in conventional stress management interventions and self-help literature. Moreover, this study provided a first step toward more detailed and standardized taxonomies, which can be used to investigate evidence-based content in stress management interventions and enable greater comparability between different intervention types.

    This project describes the application of the "sterile cockpit rule," a crew resource management (CRM) technique, targeted to improve efficacy and safety for nursing assistants in the performance of patient care duties. Crew resource management techniques have been successfully implemented in the aviation industry to improve flight safety. Application of these techniques can improve patient safety in medical settings. The Veterans Affairs (VA) National Center for Patient Safety conducted a CRM training program in select VA nursing units. One unit developed a novel application of the sterile cockpit rule to create protected time for certified nursing assistants (CNAs) while they collected vital signs and blood glucose data at the beginning of each shift. The typical nursing authority structure was reversed, with senior nurses protecting CNAs from distractions. This process led to improvements in efficiency and communication among nurses, with the added benefit of increased staff morale. Crew resource management techniques can be used to improve efficiency, morale, and patient safety in the healthcare setting.

    Li, Min; Yao, Richard; Yan, Xiaolang

    2011-01-01

    When applying Dynamic Power Management (DPM) technique to pervasively deployed embedded systems, the technique needs to be very efficient so that it is feasible to implement the technique on low end processor and tight-budget memory. Furthermore, it should have the capability to track time varying behavior rapidly because the time varying is an inherent characteristic of real world system. Existing methods, which are usually model-based, may not satisfy the aforementioned requirements. In this paper, we propose a model-free DPM technique based on Q-Learning. Q-DPM is much more efficient because it removes the overhead of parameter estimator and mode-switch controller. Furthermore, its policy optimization is performed via consecutive online trialing, which also leads to very rapid response to time varying behavior.

    2016-01-01

    We applied a management strategy evaluation (MSE) model to examine the potential cost-effectiveness of using pheromone-baited trapping along with conventional lampricide treatment to manage invasive sea lamprey. Four pheromone-baited trapping strategies were modeled: (1) stream activation wherein pheromone was applied to existing traps to achieve 10−12 mol/L in-stream concentration, (2) stream activation plus two additional traps downstream with pheromone applied at 2.5 mg/hr (reverse-intercept approach), (3) trap activation wherein pheromone was applied at 10 mg/hr to existing traps, and (4) trap activation and reverse-intercept approach. Each new strategy was applied, with remaining funds applied to conventional lampricide control. Simulating deployment of these hybrid strategies on fourteen Lake Michigan streams resulted in increases of 17 and 11% (strategies 1 and 2) and decreases of 4 and 7% (strategies 3 and 4) of the lakewide mean abundance of adult sea lamprey relative to status quo. MSE revealed performance targets for trap efficacy to guide additional research because results indicate that combining lampricides and high efficacy trapping technologies can reduce sea lamprey abundance on average without increasing control costs.

    Pethidine 100 mg in 30-40 ml saline was given in a group of patients by the conventional technique of intravenous regional anesthesia. Fourty percent of the patients did not feel any form of pain or discomfort, 26.7% experienced only vague sensations which did not call for additional drugs but 13.3% felt some form of pain or discomfort for which diazepam was given and was enough for surgery to be completed. In the rest of the patients (20%) there was intolerable pain for which patients were given general anesthesia. This last category was operated upon for recent fractures or digital conditions and it is known that intravenous regional anesthesia using conventional local anesthetics for such patients usually fails. In a control group in which 30-40 ml saline without pethidine were injected, there was complete failure of the technique.

    Full Text Available Introduction: Pilonidal sinus is one of the common problems encountered in general surgical practices and the management of this disease is variable, contentious and problematic. Principles of treatment require eradication of the sinus tract; complete healing and prevention of recurrence. Although several surgical techniques have been described over the years, the management remains controversial. Aims and Objectives: The aim of this study was to compare the two techniques of the open method and Z-plasty in the management of pilonidal sinus, in terms of incidence of post-operative pain, total hospital stay, total recovery time, complications and recurrence rate. Materials and Methods: This is a prospective comparative study which was conducted in the surgical department of a teaching hospital. A total of 50 cases were included in this study. Of these, 25 cases were operated by the open technique and 25 by excision and Z-plasty. Observation and Result: The mean age at presentation was 29.44 years. Male genders followed by age between 20 and 30 years were the most common predisposing factors. The mean body mass index, early and late post-operative complications were comparable between the two groups. Mean hospital stay and total recovery time was significantly more in open technique group compared with Z-plasty group. Visual analog score was also significantly more in open technique group when compared with Z-plasty group. Conclusion: Excision with Z-plasty was better technique in terms of lesser hospital stay, lesser recovery time, less post-operative pain.

    2008-01-01

    Cholangiocarcinoma is a rare malignancy of the biliary tract. Key factors in determining therapeutic options include knowledge of tumor extent, anatomy and obtaining tissue diagnosis. Endoscopically, there are three modalities available to make the diagnosis of cholangiocarcinoma. These include endoscopic retrograde cholangiopancreatography, endoscopic ultrasound with fine needle aspiration and cholangioscopy. Management of cholangiocarcinoma endoscopically is typically confined to stent placement for palliative purposes or as a bridge to surgery. In this article, we will review the endoscopic techniques available for the diagnosis and management of cholangiocarcinoma.

    2013-03-01

    Extensor tendon injuries are given less importance than the flexor tendon injuries; however, the extensor mechanism is more complicated than flexor tendon system, and regaining satisfactory function is a challenge. It has been reported that loss of digital flexion would affect grasp and power grip imposing greater functional loss than digital extensor lag. Zone 3 extensor tendon management is complex because of excessive scar formation limiting composite digital flexion and extension. The adhesions are more common if the tendon is immobilized for long period. The purpose of this care report is to describe the alternate technique in managing adhesion after prolong immobilization in zone 3 extensor tendon injuries.

    2013-08-01

    Full Text Available Vallecular Cysts (VC are laryngeal cysts found most frequently at true vocal cords followed by epiglottis and vallecula, which develops due to obstruction of the submucosal gland. In children, they present with stridor, respiratory distress, feeding difficulty, failure to thrive or as an incidental finding on laryngoscopy. The anaesthesiologist can face the risk of obstructed breathing during mask holding, obscured laryngeal view, loss of airway, rupture of cyst and potential aspiration of cyst contents. Various techniques of airway management have been described in literature. We report a series of three cases with VC where we managed the airway successfully. We also discuss the relevant literature review.

    Double-crested cormorants (Phalacrocorax auritus) have been identified as the source of significant mortality to juvenile salmonids (Oncorhynchus spp.) in the Columbia River Basin. Management plans for reducing the size of a large colony on East Sand Island (OR, USA) in the Columbia River estuary are currently being developed. We evaluated habitat enhancement and social attraction as nondestructive techniques for managing cormorant nesting colonies during 2004–2007. We tested these techniques on unoccupied plots adjacent to the East Sand Island cormorant colony. Cormorants quickly colonized these plots and successfully raised young. Cormorants also were attracted to nest and raised young on similar plots at 2 islands approximately 25 km from East Sand Island; 1 island had a history of successful cormorant nesting whereas the other was a site where cormorants had previously nested unsuccessfully. On a third island with no history of cormorant nesting or nesting attempts, these techniques were unsuccessful at attracting cormorants to nest. Our results suggest that some important factors influencing attraction of nesting cormorants using these techniques include history of cormorant nesting, disturbance, and presence of breeding cormorants nearby. These techniques may be effective in redistributing nesting cormorants away from areas where fish stocks of conservation concern are susceptible to predation, especially if sites with a recent history of cormorant nesting are available within their foraging or dispersal range.

    To investigate the parental acceptance rate to behavior management techniques (BMT) used in pediatric dentistry. Two hundred and eighty-five subjects (mother or father) were included in this survey. Five behavior management techniques including (1)tell-show-do; (2)voice control; (3)passive restraint; (4)sedation; (5) general anesthesia commonly used in pediatric dentistry were explained to the parents and then filled the questionnaires by either of the parents, including the parental age, gender, educational level and income, The answerer rated their acceptance of each technique using a visual analogue scale (VAS), a continuous scale ranging from 0 to 100mm. The left end represented "completely acceptable" and the right end represented "completely unacceptable". The subjects were instructed to rate the acceptability of each technique by placing a mark on the VAS response line. The acceptability rating of each technique by the subject was determined by measuring the distance between VAS line from the left end to the mark. SPSS10.0 software was used for statistical analysis. VAS measurements were analyzed using a factorial analysis of variance (ANOVA). Student's t test was used to analyze the difference between the acceptance rates for different gender of the answerers. The correlation between independent variables consisted of parental gender, education level, income and behavior management techniques were analyzed using Spearman correlation test. The order of decreasing acceptance rate was as follows, tell-show-do, voice control, sedation, general anesthesia and passive restraint. The difference between each of them was statistically significant (F=215.2,Panesthesia by Spearman correlation analysis (P<0.01). The acceptance rate of tell-show-do and passive restraint were related to parental gender. According to Students's t test, female tended to accept tell-show-do more than males (P=0.011), nevertheless more males tended to accept passive restraint (P=0.001). No

    Full Text Available Aim: The efficacy of a topically applied formulation of tetracaine base (6% was investigated against benzocaine in achieving pulpal anesthesia in a randomized, placebo-controlled, double-blind study. Materials and Methods: Subjects′ baseline pulpal responses to an electric pulp tester were measured, followed by a 10 min application of either tetracaine anesthetic paste (TAP, benzocaine (20%, or placebo. Treatments were removed and pulp testing was performed at 10 min, 15 min, and 20 min postapplication. Results: TAP produced significant pulpal anesthesia at 184% ± 7.2% above baseline versus 14% ± 1.7% above baseline for benzocaine at 15 min (P < 0.03. Differences between treatments were tested with the Wilcoxon test and the Steel-Dwass test, which is the nonparametric version of the all-pairs Tukey′s honestly significant difference test. Conclusion: Achieving profound anesthesia with a topical anesthetic paste could lead to injection less procedure, improved postsurgical incisional pain management, and ameliorate pain associated with a variety of lesions.

  6. Lung Physiology and Obesity: Anesthetic Implications for Thoracic Procedures

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Obesity is a worldwide health problem affecting 34% of the American population. As a result, more patients requiring anesthesia for thoracic surgery will be overweight or obese. Changes in static and dynamic respiratory mechanics, upper airway anatomy, as well as multiple preoperative comorbidities and altered drug metabolism, characterize obese patients and affect the anesthetic plan at multiple levels. During the preoperative evaluation, patients should be assessed to identify who is at risk for difficult ventilation and intubation, and postoperative complications. The analgesia plan should be executed starting in the preoperative area, to increase the success of extubation at the end of the case and prevent reintubation. Intraoperative ventilatory settings should be customized to the changes in respiratory mechanics for the specific patient and procedure, to minimize the risk of lung damage. Several non invasive ventilatory modalities are available to increase the success rate of extubation at the end of the case and to prevent reintubation. The goal of this review is to evaluate the physiological and anatomical changes associated with obesity and how they affect the multiple components of the anesthetic management for thoracic procedures.

    Oda, Toshiyuki; Takahama, Yutaka

    2012-11-01

    This chapter describes anesthetic consideration in patients undergoing catheter ablation for atrial fibrillation (AF) based on electrophysiologic or pharmacological aspects. In the 2011 guidelines of the Japanese Circulation Society for non-pharmacotherapy of cardiac arrhythmias, catheter ablation is recommended as Class I therapeutic modality for the patients with drug-refractory paroxysmal AF. Catheter ablation of AF is an invasive and long-lasting procedure necessitating sedation during treatment. However, in the most of the patients, sedation or anesthesia is possibly performed by cardiologists using propofol, midazolam or dexmedetomidine. Deep sedation accompanies a high risk of ventilatory or circulatory derangement. Furthermore, life-threatening complications, such as cerebral infarction or cardiac tamponade, can occur during ablation. Patients with AF are increasing in number as a trend in the aging society, resulting in an increase in catheter ablation in high risk patients. To accomplish safe anesthetic management of the patients for catheter ablations, anesthesiologists are required to have fundamental knowledge and skill in the performance of the catheter ablation.

  8. Anesthetics impact the resolution of inflammation.

    Nan Chiang

    Full Text Available BACKGROUND: Local and volatile anesthetics are widely used for surgery. It is not known whether anesthetics impinge on the orchestrated events in spontaneous resolution of acute inflammation. Here we investigated whether a commonly used local anesthetic (lidocaine and a widely used inhaled anesthetic (isoflurane impact the active process of resolution of inflammation. METHODS AND FINDINGS: Using murine peritonitis induced by zymosan and a systems approach, we report that lidocaine delayed and blocked key events in resolution of inflammation. Lidocaine inhibited both PMN apoptosis and macrophage uptake of apoptotic PMN, events that contributed to impaired PMN removal from exudates and thereby delayed the onset of resolution of acute inflammation and return to homeostasis. Lidocaine did not alter the levels of specific lipid mediators, including pro-inflammatory leukotriene B(4, prostaglandin E(2 and anti-inflammatory lipoxin A(4, in the cell-free peritoneal lavages. Addition of a lipoxin A(4 stable analog, partially rescued lidocaine-delayed resolution of inflammation. To identify protein components underlying lidocaine's actions in resolution, systematic proteomics was carried out using nanospray-liquid chromatography-tandem mass spectrometry. Lidocaine selectively up-regulated pro-inflammatory proteins including S100A8/9 and CRAMP/LL-37, and down-regulated anti-inflammatory and some pro-resolution peptides and proteins including IL-4, IL-13, TGF-â and Galectin-1. In contrast, the volatile anesthetic isoflurane promoted resolution in this system, diminishing the amplitude of PMN infiltration and shortening the resolution interval (Ri approximately 50%. In addition, isoflurane down-regulated a panel of pro-inflammatory chemokines and cytokines, as well as proteins known to be active in cell migration and chemotaxis (i.e., CRAMP and cofilin-1. The distinct impact of lidocaine and isoflurane on selective molecules may underlie their opposite

    2014-10-02

    Infection is a devastating complication of total hip arthroplasty (THA). Risk factors have been recognised and prevention is possible. The nature of the disease is heterogeneous and for satisfactory management one has to weigh factors related to pathogen, host, local soft tissue, bone stock, surgeon experience and financial resources. Available data in the current literature is of poor quality and there is a lack of data comparing different techniques. Referral of patients to dedicated departments with the appropriate facilities may be more appropriate.

    2015-01-01

    Background A delayed post-pancreatoduodenectomy haemorrhage is associated with a significant increase in peri-operative mortality. Endovascular techniques are frequently used for a delayed haemorrhage. However, limited data exists on the short- and long-term outcomes of this approach. A retrospective review over a 10-year period at a quaternary-referral pancreatic centre was performed. Methods Between 2002–2012, 1430 pancreatoduodenectomies were performed, and 32 patients had a delayed haemorrhage (occurring >24 h post-operatively) managed by endovascular techniques. The clinicopathological variables related to a haemorrhage were investigated. Results A total of 42 endovascular procedures were performed at a median of 25 days, with the majority of delayed haemorrhages occurring after 7 days. There were four deaths (13%) with three occurring in patients with a grade C haemorrhage. Seven patients (22%) experienced rebleeding, and two patients developed hepatic abscesses. Conclusion A delayed haemorrhage post-pancreaticoduodenectomy can be managed by endovascular techniques with acceptable morbidity and mortality. Rebleeding and hepatic abscesses may occur and can be managed non-operatively in most cases. The association of a delayed haemorrhage with a pancreatic fistula makes this a challenging clinical problem. PMID:26235930

    2013-01-01

    Full Text Available Background: Trichobezoar which were traditionally managed by open surgical retrieval are now often managed by minimally invasive surgical approach. Removal of a large trichobezoar by laparoscopy, however, needs an incision (usually 4-5 cm in size for specimen removal and has the risk of intra-peritoneal spillage of hair and inspissated secretions. Materials and Methods : The present paper describes a modified laparoscopy-assisted technique with temporary gastrocutaneopexy for the effective removal of a large trichobezoar using a camera port and a 4-5 cm incision (which is similar to that needed for specimen removal during laparoscopy. Results: Three patients with large trichobezoar were managed with the described technique. The average duration of surgery was 45 (30-60 min and the intraoperative blood loss was minimal. There was no peritoneal spillage and the trichobezoar could be retrieved through a 4-5 cm incision in all patients. All had an uneventful recovery and at a median followup of 6 months had excellent cosmetic and functional results. Conclusion: The described technique is a minimally invasive alternative for trichobezoar removal. There is no risk of peritoneal contamination and the technical ease and short operative time in addition to an incision limited to size required for the specimen removal, makes it an attractive option.

  17. Hypoxic pulmonary vasoconstriction: physiology and anesthetic implications.

    Lumb, Andrew B; Slinger, Peter

    2015-04-01

    Hypoxic pulmonary vasoconstriction (HPV) represents a fundamental difference between the pulmonary and systemic circulations. HPV is active in utero, reducing pulmonary blood flow, and in adults helps to match regional ventilation and perfusion although it has little effect in healthy lungs. Many factors affect HPV including pH or PCO2, cardiac output, and several drugs, including antihypertensives. In patients with lung pathology and any patient having one-lung ventilation, HPV contributes to maintaining oxygenation, so anesthesiologists should be aware of the effects of anesthesia on this protective reflex. Intravenous anesthetic drugs have little effect on HPV, but it is attenuated by inhaled anesthetics, although less so with newer agents. The reflex is biphasic, and once the second phase becomes active after about an hour of hypoxia, this pulmonary vasoconstriction takes hours to reverse when normoxia returns. This has significant clinical implications for repeated periods of one-lung ventilation.

  18. Innovative techniques for estimating illegal activities in a human-wildlife-management conflict.

    Directory of Open Access Journals (Sweden)

    Paul Cross

    Full Text Available Effective management of biological resources is contingent upon stakeholder compliance with rules. With respect to disease management, partial compliance can undermine attempts to control diseases within human and wildlife populations. Estimating non-compliance is notoriously problematic as rule-breakers may be disinclined to admit to transgressions. However, reliable estimates of rule-breaking are critical to policy design. The European badger (Meles meles is considered an important vector in the transmission and maintenance of bovine tuberculosis (bTB in cattle herds. Land managers in high bTB prevalence areas of the UK can cull badgers under license. However, badgers are also known to be killed illegally. The extent of illegal badger killing is currently unknown. Herein we report on the application of three innovative techniques (Randomized Response Technique (RRT; projective questioning (PQ; brief implicit association test (BIAT for investigating illegal badger killing by livestock farmers across Wales. RRT estimated that 10.4% of farmers killed badgers in the 12 months preceding the study. Projective questioning responses and implicit associations relate to farmers' badger killing behavior reported via RRT. Studies evaluating the efficacy of mammal vector culling and vaccination programs should incorporate estimates of non-compliance. Mitigating the conflict concerning badgers as a vector of bTB requires cross-disciplinary scientific research, departure from deep-rooted positions, and the political will to implement evidence-based management.

    Submucosal hemorrhoidectomy (Parks' procedure) is a recognized method for treating acute hemorrhoidal crisis. Anoderm preservation has been stressed in various techniques described for elective or emergency excisional hemorrhoidal management. Mucopexy techniques have been proven useful as an adjunct to minimally resectional techniques. A modified submucosal technique with anoderm preservation and mucopexy was applied to 45 patients who presented on an emergency basis with hemorrhoidal crisis. External piles were minimally removed, the minimum possible amount of diseased mucosa was excised, a linear incision was used at the anoderm to enter the subanodermal/mucosal plane to achieve the submucosal excision, and a mucopexy was added at the approximation of the mucosal flaps. Postoperative morbidity was minimal and pain after the procedure remained at acceptable levels. This technique allows for an excision limited to the pathology with important anatomic tissue preservation. This results in conservation of the sensitive and useful anoderm, a decreased risk of stenosis, and addresses the mucosal prolapse. The level of postoperative pain with this technique is acceptable and long-term follow-up reveals a high degree of patient satisfaction.

    Full Text Available Recently the Customer Relationship Management (CRM has been achieved an increasing popularity in business management. CRM includes all the steps which an organization employs to create and establish beneficial relationships with the customers. Using technologies such as data warehousing and data mining CRM can be introduced as a new area where companies can gain the competitive advantage. Via CRM system a company can improve its processes to deliver better service at a lower cost. By use of data mining techniques, companies can extract hidden information of the customers from large databases. So, organizations can determine the value of customers and predict their future behavior and requirements. Data mining tools can answer business questions which were time-consuming to track in the past. We believe that it is possible to improve CRM efficiency, to have an effective and rapid response to customer needs, by integrating CRM and data mining techniques. In this study we investigate major concepts of CRM and data mining. Also we introduce our idea to employ data mining techniques in CRM. This study show that using data mining techniques in CRM will improve CRM's efficiency and provide a better prediction ability to companies, organizations and industries to achieve more Profitability.

    Problem-solving processes in value management (VM) workshops in the construction industry are experience-based, and the quality of these workshops depends very much on the experience of the team members. The efficiency and effectiveness of VM workshops can be improved by better reusing the experi-ence of previous VM cases and field knowledge. This paper describes a new approach to facilitate VM workshops in the construction industry using data mining (DM) techniques. The feasibility of integrating DM techniques with VM workshops in the construction industry is demonstrated in case studies. Examples are presented to illustrate different methods of applying DM tools in VM workshops. The results show that DM techniques can help team members in VM workshops to understand their problems more clearly and to generate more ideas for current problems.

    2009-01-01

    Laparoscopic nephroureterectomy (LNU) is becoming an increasingly common alternative treatment for transitional cell carcinoma (TCC) of the renal pelvis and ureter due to decreased perioperative morbidity, shorter hospitalization, and comparable oncologic control with open nephroureterectomy (ONU). Mobilization of the kidney and proximal ureter may be performed through a transperitoneal, retroperitoneal, or hand-assisted approach. Each technique is associated with its own benefits and limitations, and the optimal approach is often dictated by surgeon preference. Our analysis of the literature reflects equivalent cancer control between LPN and OPN at intermediate follow-up with significantly improved perioperative morbidity following LPN. Several methods for bladder cuff excision have been advocated, however, no individual technique for management of the distal ureter proved superior. Overall, complete en-bloc resection with minimal disruption of the urinary tract should be optimized to maintain oncologic outcomes. Longer follow-up and prospective studies are needed to fully evaluate these techniques. PMID:19148293

    The importance of using remote sensing techniques, in the visible and near-infrared ranges, for mapping, inventory, conservation and management of natural ecosystems is discussed. Some examples realized in Brazil or other countries are given to evaluate the products from orbital platform (MSS and RBV imagery of LANDSAT) and aerial level (photography) for ecosystems study. The maximum quantitative and qualitative information which can be obtained from each sensor, at different level, are discussed. Based on the developed experiments it is concluded that the remote sensing technique is a useful tool in mapping vegetation units, estimating biomass, forecasting and evaluation of fire damage, disease detection, deforestation mapping and change detection in land-use. In addition, remote sensing techniques can be used in controling implantation and planning natural/artificial regeneration.

    Intervention studies have demonstrated the benefit of stress management techniques on health-related variables among school-age children. It was hypothesized that teaching elementary school children stress management skills would promote appropriate classroom study behavior by enhancing student ability to attend to teacher assigned tasks. This pilot study supports the contention that stress management skills can increase classroom "on-task" behavior.

    Airway emergencies presenting to the emergency department (ED) are usually managed with conventional equipment and techniques. The patient group managed urgently in the operating room (OR) has not been described. This study aims to describe a case series of children presenting to the ED with airway emergencies managed urgently in the OR, particularly the anaesthetic equipment and techniques used and airway findings. A retrospective cohort study undertaken at The Royal Children's Hospital, Melbourne, Australia. All patients presenting to the ED between 1 January 2012 and 30 July 2015 (42 months) with an airway emergency who were subsequently managed in the OR were included. Patient characteristics, anaesthetic equipment and technique and airway findings were recorded. Twenty-two airway emergencies in 21 patients were included over the study period, on average one every 2 months. Median age was 18 months and 43% were male. Inhalational induction was used in 77.3%, combined inhalational and intravenous induction in 9.1%, and intravenous induction alone in 13.6%. The most commonly used inhalational induction agent was sevoflurane, and the most commonly used intravenous induction agents were ketamine and propofol. Ten airway emergencies did not require intubation, seven for removal of inhaled foreign body, two with progressive tracheal stenosis requiring emergent dilatation and one examination under anaesthesia to rule out inhaled foreign body. Of the 12 airway emergencies that required immediate intubation, direct laryngoscopy was used in 9 and fibre-optic intubating bronchoscopy in 3. For intubations performed by direct laryngoscopy, one was difficult (Cormack and Lehane grade 3). First pass success was 83.3%. Adverse events occurred in 3/22 (13.6%) cases. Advanced airway techniques, including inhalational induction and intubation via fibre-optic intubating bronchoscope, are rarely but predictably required in the management of patients presenting to the ED

    The present study was conducted to evaluate human pain perception at different phases of dental surgery using a computer controlled device, the Single Tooth Anesthesia System (STA System), versus the traditional syringe technique. One hundred healthy patients participated in this single-blind split-mouth design study. Individuals provided pain ratings at needle insertion, delivery of anesthetic solution and tooth extraction via a numeric visual rating scale or NVRS. The anterior middle superior alveolar, or AMSA, injection was compared with traditional syringe injections in maxillary quadrants. NVRS scores for AMSA were significantly lower for the STA System when compared to traditional syringe technique at needle insertion, delivery of anesthetic solution (p less than 0.0001) and also during tooth extractions (p=0.0002). A higher percentage of patients (23 percent) required a second injection after the traditional syringe technique. Subjects reported having less clinical pain with AMSA injection at every step of the dental surgery. The STA System combines an anesthetic pathway and controlled flow rate resulting in virtually imperceptible needle insertion and injection, and a rapid onset of profound anesthesia. NVRS scoring system facilitated patient comprehension in assessing pain value and intensity experienced. The two anesthetic delivery techniques were therapeutically equivalent for maxillary injections but AMSA/computer controlled protocol significantly minimizes subjective pain perception at needle insertion, anesthetic delivery and during tooth extraction.

    The objectives of this study were to evaluate the use of a transpulmonary thermodilution (Trans) technique for the measurement of cardiac output, and to determine the agreement between Trans and conventional thermodilution (TD) in anesthetized cats. Using each technique, cardiac output was measured in 5 mature cats (weights 2.4 to 5.6 kg) anesthetized with isoflurane. To induce different levels of cardiac output in each cat, anesthesia was maintained at > 1.5x end-tidal minimum alveolar concentration (MAC) of isoflurane, and at 1.3x end-tidal isoflurane MAC with and without administration of dobutamine. At least 2 comparisons between TD and Trans values were made at each cardiac output rate. Thirty-two of the 42 recorded comparisons were analyzed. Linear regression analysis (TD vs Trans) yielded an r(2) value of 0.83. The mean bias (TD-Trans) was -3.7 mL/kg/min with limits of agreement of -35.9 to 28.5 mL/kg/min. The concordance coefficient was 0.91. The Trans method showed good relationship and good agreement with TD in anesthetized cats. The Trans method is a relatively noninvasive, practical, and safe method to measure cardiac output in anesthetized cats.

    Increasing population and water conflicts are making water management one of the most important issues of the present world. It has become absolutely necessary to find ways to manage water more efficiently. Technological advancement has introduced various techniques for data acquisition and analysis, and these tools can be used to address some of the critical issues that challenge water resource management. This research used learning machine techniques and information acquired through remote sensing, to solve problems related to soil moisture estimation and crop identification on large spatial scales. In this dissertation, solutions were proposed in three problem areas that can be important in the decision making process related to water management in irrigated systems. A data assimilation technique was used to build a learning machine model that generated soil moisture estimates commensurate with the scale of the data. The research was taken further by developing a multivariate machine learning algorithm to predict root zone soil moisture both in space and time. Further, a model was developed for supervised classification of multi-spectral reflectance data using a multi-class machine learning algorithm. The procedure was designed for classifying crops but the model is data dependent and can be used with other datasets and hence can be applied to other landcover classification problems. The dissertation compared the performance of relevance vector and the support vector machines in estimating soil moisture. A multivariate relevance vector machine algorithm was tested in the spatio-temporal prediction of soil moisture, and the multi-class relevance vector machine model was used for classifying different crop types. It was concluded that the classification scheme may uncover important data patterns contributing greatly to knowledge bases, and to scientific and medical research. The results for the soil moisture models would give a rough idea to farmers

    Over the past two decades, transcatheter arterial embolization has become the first-line therapy for the management of upper gastrointestinal bleeding that is refractory to endoscopic hemostasis. Advances in catheter-based techniques and newer embolic agents, as well as recognition of the effectiveness of minimally invasive treatment options, have expanded the role of interventional radiology in the management of hemorrhage for a variety of indications, such as peptic ulcer bleeding, malignant disease, hemorrhagic Dieulafoy lesions and iatrogenic or trauma bleeding. Transcatheter interventions include the following: selective embolization of the feeding artery, sandwich coil occlusion of the gastroduodenal artery, blind or empiric embolization of the supposed bleeding vessel based on endoscopic findings and coil pseudoaneurysm or aneurysm embolization by three-dimensional sac packing with preservation of the parent artery. Transcatheter embolization is a fast, safe and effective, minimally invasive alternative to surgery when endoscopic treatment fails to control bleeding from the upper gastrointestinal tract. This article reviews the various transcatheter endovascular techniques and devices that are used in a variety of clinical scenarios for the management of hemorrhagic gastrointestinal emergencies.

    Full Text Available The integration of biodiversity into forest management has traditionally been a challenge for many researchers and practitioners. In this paper, we have provided a survey of forest management papers that use different Operations Research (OR methods in order to integrate biodiversity objectives into their planning models. One hundred and seventy-nine references appearing in the ISI Web of Science database in the last 30 years have been categorized and evaluated according to different attributes like model components, forest management elements, or biodiversity issues. The results show that many OR methods have been applied to deal with this challenging objective. Thus, up to 18 OR techniques, divided into four large groups, which have been employed in four or more articles, have been identified. However, it has been observed how the evolution of these papers in time apparently tended to increase only until 2008. Finally, two clear trends in this set of papers should be highlighted: the incorporation of spatial analysis tools into these operational research models and, second, the setting up of hybrid models, which combine different techniques to solve this type of problem.

    In support of the National Low-Level Waste (LLW) Management Research and Development Program being carried out at Oak Ridge National Laboratory, Science Applications, Inc., conducted a survey of models and monitoring techniques associated with the transport of radionuclides and other chemical species from LLW burial sites. As a result of this survey, approximately 350 models were identified. For each model the purpose and a brief description are presented. To the extent possible, a point of contact and reference material are identified. The models are organized into six technical categories: atmospheric transport, dosimetry, food chain, groundwater transport, soil transport, and surface water transport. About 4% of the models identified covered other aspects of LLW management and are placed in a miscellaneous category. A preliminary assessment of all these models was performed to determine their ability to analyze the transport of other chemical species. The models that appeared to be applicable are identified. A brief survey of the state-of-the-art techniques employed to monitor LLW burial sites is also presented, along with a very brief discussion of up-to-date burial techniques.

    Full Text Available We present a novel active queue management (AQM technique to demonstrate the efficacy of practically harnessing the predictive utility of SSR indications for improved video communication. We consider a network within which corrupted packets are relayed over multiple hops, but a certain percentage of packets needs to be dropped at an intermediate node due to congestion. We propose an AQM technique, survival of the fittest (SOTF, to be employed at the relay node, within which we use packet state information, available from SSR indications and checksums, to drop packets with the highest corruption levels. On the basis of actual 802.11b measurements we show that such a side information (SI aware processing within the network can provide significant performance benefits over an SI-unaware scheme, random queue management (RQM, which is forced to randomly discard packets. With trace-based simulations, we show the utility of the proposed AQM technique in improving the error recovery performance of cross-layer FEC schemes. Finally, with the help of H.264-based video simulations these improvements are shown to translate into a significant improvement in video quality.

    Full Text Available Pain is not the sole reason for fear of dentistry. Anxiety or the fear of unknown during dental treatment is a major factor and it has been the major concern for dentists for a long time. Therefore, the main aim of this study was to evaluate and compare the two distraction techniques, viz, audio distraction and audiovisual distraction, in management of anxious pediatric dental patients. Sixty children aged between 4-8 years were divided into three groups. Each child had four dental visits - screening visit, prophylaxis visit, cavity preparation and restoration visit, and extraction visit. Child′s anxiety level in each visit was assessed using a combination of four measures: Venham′s picture test, Venham′s rating of clinical anxiety, pulse rate, and oxygen saturation. The values obtained were tabulated and subjected to statistical analysis. It was concluded that audiovisual distraction technique was more effective in managing anxious pediatric dental patient as compared to audio distraction technique.

    2017-01-01

    Background Chronic stress has been shown to be associated with disease. This link is not only direct but also indirect through harmful health behavior such as smoking or changing eating habits. The recent mHealth trend offers a new and promising approach to support the adoption and maintenance of appropriate stress management techniques. However, only few studies have dealt with the inclusion of evidence-based content within stress management apps for mobile phones. Objective The aim of this study was to evaluate stress management apps on the basis of a new taxonomy of effective emotion-focused stress management techniques and an established taxonomy of behavior change techniques. Methods Two trained and independent raters evaluated 62 free apps found in Google Play with regard to 26 behavior change and 15 emotion-focused stress management techniques in October 2015. Results The apps included an average of 4.3 behavior change techniques (SD 4.2) and 2.8 emotion-focused stress management techniques (SD 2.6). The behavior change technique score and stress management technique score were highly correlated (r=.82, P=.01). Conclusions The broad variation of different stress management strategies found in this sample of apps goes in line with those found in conventional stress management interventions and self-help literature. Moreover, this study provided a first step toward more detailed and standardized taxonomies, which can be used to investigate evidence-based content in stress management interventions and enable greater comparability between different intervention types.

    The oncologic management of breast cancer has evolved over the past several decades from radical mastectomy to modern-day preservation of chest and breast structures. The increased rate of mastectomies over recent years made breast reconstruction an integral part of the breast cancer management. Plastic surgery now offers patients a wide variety of reconstruction options from primary closure of the skin flaps to performance of microvascular and autologous tissue transplantation. Well-coordinated partnerships between surgical oncologists, plastic surgeons, and patients address concerns of tumor control, cosmesis, and patients' wishes. The gamut of breast reconstruction options is reviewed, particularly noting state-of-the-art techniques, as well as the advantages and disadvantages of various timing modalities.

    The purpose of this study was to determine the results of a new technique for management of prostatic retention cysts in dogs. A retrospective clinical study. Eighteen client-owned dogs. Dogs with prostatic retention cysts were treated by celiotomy and drainage of the cysts. The majority of the cyst wall was resected and residual cyst cavities were packed with omentum. All dogs were castrated. Long-term resolution of clinical signs was achieved in all dogs, with follow-up periods ranging from 6 to 42 months. Five dogs developed urinary incontinence postoperatively. This persisted in two dogs, but was well controlled with phenylpropanolamine. In the remaining dogs, the incontinence was transient and resolved within 2 months of surgery. Partial cyst resection combined with omentalization and castration was a simple and effective means of managing prostatic retention cysts. The incidence of serious complications, including postoperative urinary incontinence, was low.

    Full Text Available Quality management is an important aspect in all kinds of businesses – manufacturing or service. Idea generation plays a pivotal role in managing quality in organizations. It is thenew and innovative ideas which can help corporations to survive in the turbulent business environment. Research in group dynamics has shown that more ideas are generated by individuals working alone but in a group environment than the individuals engaged in a formal group discussion. In Nominal Group Technique (NGT, individuals work alone but in a group setting. This paper shows how NGT can be applied to generate large number of ideas to solve quality related problems specifically in Malaysian higher education setting. The paper also discusses the details of NGT working procedure andexplores the areas of its further applications.
