    In the past, rudimentary devices were used to record surgical operations. Currently, the introduction of technologic advances such as high-definition television and the miniaturization of high-resolution digital video cameras provides an opportunity for making significantly enhanced surgical records. These enhancements, coupled with the recent advances in telemedicine and surgical simulation, will improve cardiac surgery training and skill acquisition, decrease operative times and costs, minimize morbidity, and improve overall patient care. The present paper provides a discussion of the media technology offered to surgeons for recording a surgical procedure on video. Hardware technology, including different types of cameras and analogical or digital post processing methods, are reviewed with a surgical ''eye''. This ''how to'' paper provides practical suggestions to surgeons in order to enhance surgical video recording. PMID:18670389

  2. Fontan procedure: imaging of normal post-surgical anatomy and the spectrum of cardiac and extracardiac complications

    International Nuclear Information System (INIS)

    Univentricular congenital heart diseases include a range of entities that result in a functionally single ventricular chamber. Although the only curative therapy is cardiac transplantation, there are several palliative surgical techniques that prevent ventricular volume overload, diverting part or all the systemic venous circulation into the pulmonary arteries. The modern Fontan procedure, which consists of anastomosing both the superior (SVC) and inferior vena cava (IVC) to the right pulmonary artery (RPA), is nowadays the last step before transplantation. The importance of imaging in these entities lies not only in the understanding of the new circuit established after surgical correction, but also in the early detection of the wide spectrum of cardiac and extracardiac complications that can occur due to the new physiological condition. Due to the increased survival of these patients, long-term complications are becoming more common. The main cardiac complications are atrial enlargement, ventricular dysfunction, and stenosis or thrombosis of the conduit. Pulmonary artery stenosis, pulmonary arteriovenous fistulae (PAVF), systemic-pulmonary veno venous shunts (VVS), hepatic congestion, cardiac cirrhosis, and protein-losing enteropathy are potential extracardiac complications. - Highlights: • Fontan procedure is the main palliative surgical procedure for univentricular heart correction. • Fontan procedure entails the anastomosis of SVC and IVC to the RPA. • Complications are becoming more common due to the increased survival of patients with Fontan

    Several modern learning frameworks (eg, cognitive apprenticeship, anchored instruction, and situated cognition) posit the utility of nontraditional methods for effective experiential learning. Thus, development of novel educational tools emphasizing the cognitive framework of operative sequences may be of benefit to surgical trainees. We propose the development and global deployment of an effective, mobile cognitive cardiac surgical simulator. In methods, 16 preclinical medical students were assessed. Overall, 4 separate surgical modules (sternotomy, cannulation, decannulation, and sternal closure) were created utilizing the Touch Surgery (London, UK) platform. Modules were made available to download free of charge for use on mobile devices. Usage data were collected over a 6-month period. Educational efficacy of the modules was evaluated by randomizing a cohort of medical students to either module usage or traditional, reading-based self-study, followed by a multiple-choice learning assessment tool. In results, downloads of the simulator achieved global penetrance, with highest usage in the USA, Brazil, Italy, UK, and India. Overall, 5368 unique users conducted a total of 1971 hours of simulation. Evaluation of the medical student cohort revealed significantly higher assessment scores in those randomized to module use versus traditional reading (75% ± 9% vs 61% ± 7%, respectively; P < 0.05). In conclusion, this study represents the first effort to create a mobile, interactive cognitive simulator for cardiac surgery. Simulators of this type may be effective for the training and assessment of surgical students. We investigated whether an interactive, mobile-computing-based cognitive task simulator for cardiac surgery could be developed, deployed, and validated. Our findings suggest that such simulators may be a useful learning tool. PMID:27568126

    Full Text Available Paralysis of diaphragm on one or, exceptionally, both sides is a common cause of delayed recovery and excessive morbidity following pediatric cardiac surgery. The consequences of this complication after all forms of congenital heart surgery in newborns and young infants can be potentially serious. The impact of diaphragmatic palsy on the physiology after single ventricle palliations is particularly significant. It is necessary for all professionals taking care of children with heart disease to be familiar with the etiology, diagnosis, and management of this condition. Early recognition and prompt management of diaphragmatic palsy can potentially reduce the duration of mechanical ventilation and intensive care in those who develop this complication. This review summarizes the anatomy of the phrenic nerves, reasons behind the occurrence of diaphragmatic palsy, and suggests practical guidelines for management.

    Left ventricular pressure overload in response to aortic banding is an invaluable model for studying progression of cardiac hypertrophy and transition to heart failure. Traditional aortic banding has recently been superceded by minimally invasive transverse aortic banding (MTAB), which does not require ventilation so is less technically challenging. Although the MTAB approach is superior, few laboratories have documented success, and minimal information on the model is available. The aim of this study was to optimize conditions for MTAB and to characterize the development and progression of cardiac hypertrophy. Isofluorane proved the most suitable anaesthetic for MTAB surgery in mice, and 1 week after surgery the MTAB animals showed significant increases in systolic blood pressure (MTAB 110 ± 6 mmHg versus sham 78 ± 3 mmHg, n = 7, P MTAB 6.2 ± 0.2 versus sham 5.1 ± 0.1, n = 12, P MTAB 31.7 ± 1% versus sham 36.6 ± 1.4%, P = 0.01) and diastolic dysfunction (e.g. left ventricular end-diastolic pressure, MTAB 12.7 ± 1.0 mmHg versus sham 6.7 ± 0.8 mmHg, P MTAB hearts, signifying an inflammatory response. More pronounced remodelling was observed 4 weeks postsurgery (heart weight to body weight ratio, MTAB 9.1 ± 0.6 versus sham 4.6 ± 0.04, n = 10, P MTAB 24.3 ± 2.5% versus sham 43.6 ± 1.7%, n = 10, P = 0.003), together with a significant increase in cardiac fibrosis and further cardiac inflammation. Our findings demonstrate that MTAB is a relevant experimental model for studying development and progression of cardiac hypertrophy, which will be highly valuable for future studies examining potential novel therapeutic interventions in this setting.

    Full Text Available Stefania Tenna, Pietro Francesco Delle Femmine, Alfonso Luca Pendolino, Beniamino Brunetti, Paolo Persichetti Plastic Surgery Unit, University Campus Bio-Medico of Rome, University of Rome, Rome, Italy Abstract: In recent years, the number of people getting tattoos has continued to increase. Tattoos are much more than cultural fads and cosmetic complements, and nowadays often represent events that express the patient's personality without words. The presence of a tattoo in the surgical field may be a problem for both the patient and the surgeon. However, the relevant literature is mostly based on complications related to application of tattoos or methods used to remove them. To date, few reports have focused on the importance of preserving a tattoo during a surgical procedure, and no organized studies could be found. The aim of this paper is to provide an overview of the range of solutions that surgeons can use to preserve tattoos during surgery. A PubMed database search was done to assess other surgeons' experience. The terms "tattoo" in combination with "incision", "surgery", "surgical", or "operative" were used as key words. Following a review of the literature, photographs of patients presenting with a tattoo in the last 5 years at University Campus Bio-Medico of Rome were identified in order to determine the frequency of patients presenting with tattoos in our department. The patients were classified according to sex, age, type of surgery, number of tattoos, and tattoo location. Specific requests to preserve tattoos were recorded. Finally, an algorithm of treatment according to tattoo dimension and location is proposed. Knowledge of all the strategies available for saving tattoos is important for plastic and cosmetic surgeons. If a tattooed area needs to be operated on, surgeons should attempt, when possible, to avoid altering the tattoo in order to maximize the final cosmetic result. Keywords: tattoo incision, body contouring, surgery

    Full Text Available The Sushruta Samhita is an Ayurvedic text, by the legendary Sushruta, foundational to Ayurvedic medicine (Indian traditional medicine, with innovative chapters mainly on surgery. There is a general impression that Sushruta Samhita is only an ancient Indian Ayurvedic text book of surgery. Sushruta Samhita contains 184 chapters and description of 1120 illnesses, 700 medicinal plants, a detailed study on anatomy, 64 preparations from mineral sources and 57 preparations based on animal sources. It still retains the land mark position in the field of surgical texts. In addition to his worldwide known work of historical significance on plastic surgery, he also made similar unique contributions on numerous aspects of medicine, such as fracture and dislocations, urinary stones, skin diseases including leprosy, Pancha Karma (Purification procedures, toxicology, pediatrics, eye diseases, psychiatry, obstetrics and gynaecology, etc. A very limited conceptual work has been performed on the selected chapters of Sushruta Samhita. Therefore a review conceptual study has been carried out on the various surgical concepts of Sushruta Samhita. Outcome of this study shows, Sushruta Samhita is written in the aphorism form and the techniques described in it are eminently in line with technical abilities of the times. It is need of the hour to explore the hidden truth by decoding the versions of the texts.

  14. Radiation exposure during cardiac catheterization procedures

    International Nuclear Information System (INIS)

    For some time there has been an increased interest in more information about radiation exposure during cardiac catheterization because of: relatively high doses to workers and patient; rapid increase of numbers of examinations; introduction of new procedure-types (e.g. Percutaneous Transluminal Coronary Angiography, PTCA) and introduction of new techniques (e.g. Digital Subtraction Angiography, DSA). This paper reports about a study on the exposure to medical personnel and patient in two major hospitals in the Netherlands. The Total number of cardiac catheterization procedures in both hospitals amounts to circa 3000 per year (approximately 10% of all cardiac procedures c.q. 20% of all PTCA procedures in the Netherlands). This study is related to 1300 cardiac examinations

    As a result of the trend toward late childbearing, fertility preservation has become a major issue in young women with gynaecological cancer. Fertility-sparing treatments have been successfully attempted in selected cases of cervical, endometrial and ovarian cancer, and gynaecologists should be familiar with fertility-preserving options in women with gynaecological malignancies. Options to preserve fertility include shielding to reduce radiation damage, fertility preservation when undergoing cytotoxic treatments, cryopreservation, assisted reproduction techniques, and fertility-sparing surgical procedures. Radical vaginal trachelectomy with laparoscopic lymphadenectomy is an oncologically safe, fertility-preserving procedure. It has been accepted worldwide as a surgical treatment of small early stage cervical cancers. Selected cases of early stage ovarian cancer can be treated by unilateral salpingo-ophorectomy and surgical staging. Hysteroscopic resection and progesterone treatment are used in young women who have endometrial cancer to maintain fertility and avoid surgical menopause. Appropriate patient selection, and careful oncologic, psychologic, reproductive and obstetric counselling, is mandatory. PMID:22503435

  16. Surgical Procedures of Morbid Obesity

    Full Text Available Background: Surgical intervention has been recently advocated in the treatment of morbid obesity. The objective of this study was to review surgery as an alternative in the treatment of morbidly obese adolescents. Materials and Methods: This research was conducted by searching English websites such as PubMed, Up to Date, and Google Scholar, as well as some Persian websites including SID, Iranmedex, and Magiran. Articles published from 2000 to 2010 on interventional and clinical trials were reviewed for treatment of morbid obesity in adolescents. Keywords used in internet searches include obesity; adolescence; and surgery.Results: The results obtained from the studies indicated that 4% of American adolescents suffer from morbid obesity. So far, pharmacological treatment and other approaches toward this type of obesity have been inefficient. Hence, surgery was employed as one of the new approaches to the treatment of this disorder. According to the National Health Institute criteria, in the treatment of adolescent candidates for surgery, anthropometric measurements are performed together with the measurement of other co-morbidities of obesity. Adolescents whose percentiles are ≥99 are considered as morbidly obese patients. Conclusion: The results of the studies suggested that for the extremely obese adolescents, who do not respond to other types of medical interventions within 6 months, surgery can be performed. Adolescents with BMI of ≥40 kg/m2 and skeletal maturity, or those with co morbidities of obesity, or 13-year-old girls and boys ≥15 years of age can be candidates for surgery. However, the side effects of obesity should not be neglected. Therefore, before the adolescent obesity become morbid obesity, preventive measures should be taken through changes in lifestyle.

    In many surgeries, especially orthopedic procedures, power tools such as saws and drills are used. These tools may produce aerosolized blood and other biological material from bone and soft tissues. Surgical lasers and electrocautery tools can also produce aerosols when tissues are vaporized and condensed. Studies have been reported in the literature concerning production of aerosols during surgery, and some of these aerosols may contain infectious material. Garden et al. (1988) reported the presence of papilloma virus DNA in the fumes produced from laser surgery, but the infectivity of the aerosol was not assessed. Moon and Nininger (1989) measured the size distribution and production rate of emissions from laser surgery and found that particles were generally less than 0.5 {mu}m diameter. More recently there has been concern expressed over the production of aerosolized blood during surgical procedures that require power tools. In an in vitro study, the production of an aerosol containing the human immunodeficiency virus (HIV) was reported when power tools were used to cut tissues with blood infected with HIV. Another study measured the size distribution of blood aerosols produced by surgical power tools and found blood-containing particles in a number of size ranges. Health care workers are anxious and concerned about whether surgically produced aerosols are inspirable and can contain viable pathogens such as HIV. Other pathogens such as hepatitis B virus (HBV) are also of concern. The Occupational Safety and Health funded a project at the National Institute for Inhalation Toxicology Research Institute to assess the extent of aerosolization of blood and other tissues during surgical procedures. This document reports details of the experimental and sampling approach, methods, analyses, and results on potential production of blood-associated aerosols from surgical procedures in the laboratory and in the hospital surgical suite.

    This paper introduces a computer-based system that is designed to record a surgical procedure with multiple depth cameras and reconstruct in three dimensions the dynamic geometry of the actions and events that occur during the procedure. The resulting 3D-plus-time data takes the form of dynamic, textured geometry and can be immersively examined at a later time; equipped with a Virtual Reality headset such as Oculus Rift DK2, a user can walk around the reconstruction of the procedure room while controlling playback of the recorded surgical procedure with simple VCR-like controls (play, pause, rewind, fast forward). The reconstruction can be annotated in space and time to provide more information of the scene to users. We expect such a system to be useful in applications such as training of medical students and nurses. PMID:27046554

    In clinical practice performing any surgical procedure is inconsistent because all surgical procedures carry definitely some degree of risk. Worldwide every year millions of patients go under knife, but many of them are enduring great pain and shelling out thousands and dollars for surgeries they don't really need. This review work was planned with an intention to focus attention towards it with reporting cited evidences of unnecessary surgical operations and discuss ethical issues concern with it. In present review the references search included standard citations Google scholar, MEDLINE and PUBMED. We also used Google search engine for screening various news concern with highlighting this topic in community and online media. For articles we go through more than 60 articles from worldwide and 12 news media views from Google search in last one year. We used following quotes for their search-unnecessary surgeries, second opinion, ethical issues in unnecessary surgeries. Geographical variations were also kept in view. Our intension was highlighting ethical issues concern with unnecessary surgical operations. Henceforth we excluded such work that does not concern with ethical issues. Unnecessary surgery is that which is medically unjustifiable when the risks and costs are more than the likely therapeutic benefits or relief to the patient based on the patient's lifestyle requirements. To avoid or minimize such interventions basic seeding of ethics in curriculum and strict laws will definitely helpful in clinical practice. In conclusion, our aim was to highlight this major issue and underline need of competency based medical bioethics education in Indian scenario. PMID:27190833

    We describe a two-stage surgical approach in a patient with cardiac dysfunction and hemodynamic compromise resulting from a massive and compressive mediastinal bronchogenic cyst. To drain this cyst, video-assisted mediastinoscopy was performed as an emergency procedure, which immediately improved the patient's cardiac function. Five days later and under video thoracoscopy, resection of the cyst margins was impossible because the cyst was tightly adherent to the left atrium. We performed deroofing of this cyst through a right thoracotomy. The patient had an uncomplicated postoperative recovery, and no recurrence was observed at the long-term follow-up visit.

    A pilot study was undertaken to determine the feasibility of establishing a heart surgery programme in northern Nigeria. During three medical missions by a visiting US team, in partnership with local physicians, 18 patients with heart diseases underwent surgery at two referral hospitals in the region. Sixteen (88.9%) patients underwent the planned operative procedure with an observed 30-day mortality of 12.5% (2/16) and 0% morbidity. Late complications were anticoagulant related in mechanical heart valve patients and included a first-trimester abortion one year postoperatively, and a death at two years from haemorrhage during pregnancy. This has prompted us to now consider bioprosthetics as the valve of choice in women of childbearing age in this patient population. This preliminary result has further stimulated the interest of all stakeholders on the urgency to establish open-heart surgery as part of the armamentarium to combat the ravages of heart diseases in northern Nigeria.

    2004-10-01

    Adolescent patients are seeking plastic surgery to correct deformities or perceived deformities in increasing numbers. It is essential for the physician to understand the influence of perceived body image irregularity that motivates patients of all ages to request plastic surgery. The increased demand for plastic surgical procedures among young patients is caused partially to increased media exposure to the available procedures offered by plastic surgeons. A successful aesthetic procedure can have a positive influence on a mature, well-motivated teenager, while surgery on a psychologically unstable adolescent can be damaging to the patient. The American Society for Aesthetic Plastic Surgery has developed guidelines for the appropriate selection of teenagers for aesthetic plastic surgery [26]. First, the physician must "assess physical maturity, because operating on a feature that has not yet fully developed could interfere with growth or negate the benefits of surgery in later years." Second, the physician should explore emotional maturity and expectations of the teenager. The teenager should understand the goals and limitations of the proposed surgery and have realistic expectations. Third, only board certified plastic surgeons who operate in accredited facilities should perform these procedures, to ensure the safety of the teenager and the quality of the procedure. Finally, teenagers and their parents should understand the risks of surgery, postoperative restrictions on activity, and typical recovery times. The referring physician and surgeon must be aware of the positive or negative effects that plastic surgery can have on the life of a teenager and be able to select patients who have the motivation, maturity, psychosocial, and emotional attributes that will lead to patient satisfaction.

  7. Image-guidance for surgical procedures

    International Nuclear Information System (INIS)

    Contemporary imaging modalities can now provide the surgeon with high quality three- and four-dimensional images depicting not only normal anatomy and pathology, but also vascularity and function. A key component of image-guided surgery (IGS) is the ability to register multi-modal pre-operative images to each other and to the patient. The other important component of IGS is the ability to track instruments in real time during the procedure and to display them as part of a realistic model of the operative volume. Stereoscopic, virtual- and augmented-reality techniques have been implemented to enhance the visualization and guidance process. For the most part, IGS relies on the assumption that the pre-operatively acquired images used to guide the surgery accurately represent the morphology of the tissue during the procedure. This assumption may not necessarily be valid, and so intra-operative real-time imaging using interventional MRI, ultrasound, video and electrophysiological recordings are often employed to ameliorate this situation. Although IGS is now in extensive routine clinical use in neurosurgery and is gaining ground in other surgical disciplines, there remain many drawbacks that must be overcome before it can be employed in more general minimally-invasive procedures. This review overviews the roots of IGS in neurosurgery, provides examples of its use outside the brain, discusses the infrastructure required for successful implementation of IGS approaches and outlines the challenges that must be overcome for IGS to advance further.

    1988-07-01

    Over a 6-year period at the University Hospital in London, Ont., 101 patients underwent heart transplantation and 5 heart-lung transplantation. The authors review the general surgical problems identified from the charts of 13 of these patients. In the early postoperative period (within 30 days), laparotomy was required for pancreatitis (one), perforated peptic ulcer (two), cholecystectomy (one), pancreatic cyst (one) and appendicitis (one). In addition, a spontaneous colocutaneous fistula and spontaneous pneumoperitoneum occurred; both were managed conservatively. Later, three patients required cholecystectomy; one underwent a below-knee and a Symes amputation for dry gangrene and one surgical correction of a lymphocele. The incidence of surgical problems (13%) indicates an increased susceptibility in this group of patients. Four of the 13 patients died. Pancreatitis is a well-recognized complication of cardiac surgery; it is frequently associated with a normal or only slightly elevated serum amylase level, making a definitive diagnosis without laparotomy almost impossible. Persistence of abdominal signs should signal the need for exploratory surgery. During the early postoperative period and in the absence of multiorgan failure, immediate operation for an acute abdomen is usually successful. Despite the additional risk, cardiac transplantation does not preclude later surgery, but immunosuppression must be continued and carefully monitored. PMID:3292032

    To ensure optimal results, we must do our utmost to achieve targets based on order, symmetry and precision, our ultimate aim being to strive towards the desired harmony, planned contrast and exact proportions. Orthodontic-surgical treatments require specific finishing procedures, which most often call for multidisciplinary, or even transdisciplinary, collaboration. Finishing will involve the dental arches just as much as the orofacial environment. Above all, treatment of this kind demands a highly targeted approach in combination with well-defined and perfectly executed techniques. To finish a case satisfactorily, reasonable targets should be aimed for to ensure they are achieved. One must be ambitious and yet wise. A tight alliance of surgeon and orthodontist will nurture convincing and achievable projects and good, lifelong outcomes. Following the consolidation phase, roughly 4 to 6 weeks post-surgery, we can initiate the final orthodontic treatment, which, in effect, constitutes a mini-treatment in its own right. "Details make perfection, but perfection is not a detail" (Leonardo Da Vinci). "A lucid mind is the ante-chamber of intelligence" (Léo Ferré). In the order of life, every form of unity is always unique, and if each of us is unique, it is because everyone else is too. Ambition, wisdom, lucidity and efficiency will guarantee a successful result, the successful result. We must not be mere observers of our treatments, but the architect, project manager and site foreman at one and the same time. One could talk ad infinitum about finishing orthodontic-surgical cases because everything else leads up to the case-finishing and even the fullest description could never be exhaustive.

    Fish surgical procedures are commonplace in aquaria, zoos, laboratory facilities, and pet clinical practice. To incorporate fish surgery into a clinical setting, an understanding of anatomic differences between mammals and fish, bath anesthetics, and recirculating anesthesia techniques must be developed; a system or different size systems to accommodate anesthesia and surgery of particular species of concern at an institution or practice constructed; and familiar mammalian surgical principles applied with some adaptations. Common surgical procedures in fish include coeliotomy for intracoelomic mass removal, reproductive procedures, gastrointestinal foreign body removal, radiotransmitter placement, and integumentary mass excision.

    The growing use of cardiac implantable electronic devices (CIED) has led to infections requiring intervention. These are traditionally managed using a percutaneous transvenous approach to fully extract the culpable leads. Indications for such strategies are well-established and range from simple traction to the use of powered extraction tools including laser sheaths. Where such attempts fail, or if there are further complications, then there may be need for a cardiothoracic surgical approach. Limited evidence is currently available on the merits of individual strategies, and these are mainly drawn from case reports or series. Most utilise cardiopulmonary bypass, cardioplegic arrest and entry within the right atrium to allow direct visualisation of any vegetation and safely explant all CIED components whilst avoiding perforation, valvular and paravalvular damage. In this review, we describe a number of these and the unique challenges faced by surgeons when attempting to extract CIED. It is clear that future work should concentrate on creating clear consensus and guidelines on indications, risks and measures of efficacy outcomes for various surgical techniques. PMID:26590887

  16. Characterization of aerosols produced by surgical procedures: A summary

    International Nuclear Information System (INIS)

    In many types of surgery, especially orthopedic procedures, power tools such as saws and drills are used. These tools can impart considerable energy in disrupting tissue and may produce aerosolized blood and material from bone and other tissues. Surgical lasers and electrocautery tools can also produce aerosols due to vaporization of blood and tissues. A number of studies have been reported concerning production of aerosols during surgery, and some of the aerosols produced may contain infectious materials. Health care workers have expressed concern and questions pertaining to the occupational transmission of blood-borne pathogens including the human immunodeficiency virus (HIV) and hepatitis B virus (HBV) via blood aerosols during surgery. Little or no data existed characterizing the aerosols produced performing surgical procedures. Because of this lack of data, the National Institute for Occupational Safety and Health funded a project at ITRI to assess the extent of aerosolization of blood and other tissues during surgical procedures in the laboratory and in a hospital surgical suite

    Infants and children are a higher risk population for radiation cancer induction compared to adults. Although some values on pediatric patient doses for cardiac procedures have been reported, data to determine reference levels are scarce, especially when compared to those available for adults in diagnostic and therapeutic procedures. The aim of this study is to make a new contribution to the scarce published data in pediatric cardiac procedures and help in the determination of future dose reference levels. This paper presents a set of patient dose values, in terms of air kerma area product (KAP) and entrance surface air kerma (ESAK), measured in a pediatric cardiac catheterization laboratory equipped with a biplane x-ray system with dynamic flat panel detectors. Cardiologists were properly trained in radiation protection. The study includes 137 patients aged between 10 days and 16 years who underwent diagnostic catheterizations or therapeutic procedures. Demographic data and technical details of the procedures were also gathered. The x-ray system was submitted to a quality control programme, including the calibration of the transmission ionization chamber. The age distribution of the patients was 47 for <1 year; 52 for 1-<5 years; 25 for 5-<10 years and 13 for 10-<16 years. Median values of KAP were 1.9, 2.9, 4.5 and 15.4 Gy cm2 respectively for the four age bands. These KAP values increase by a factor of 8 when moving through the four age bands. The probability of a fatal cancer per fluoroscopically guided cardiac procedure is about 0.07%. Median values of ESAK for the four age bands were 46, 50, 56 and 163 mGy, which lie far below the threshold for deterministic effects on the skin. These dose values are lower than those published in previous papers.

    Multidetector row CT of the heart and coronary arteries is now a robust clinical method. It may be used in a number of different clinical scenarios, such as in the presence of an equivocal stress test or ambiguous clinical symptoms. Cardiac CT is also increasingly being developed as a diagnostic option for acute care such as in acute coronary syndrome. Here CT may serve as a tool to triage patients to appropriate therapy or to discharge them immediately after the investigation. The newest dual source CT also allows the assessment of cardiac function, helping to specify the diagnosis. Valve assessment by CT is still under investigation. However multidetector CT is of limited value in myocardial perfusion or for late myocardial enhancement scanning. Appropriate selection of patients for cardiac multidetector CT is mandatory so that the procedure is carried out only in those in whom it can provide clinically valuable information. (orig.)

    3D printing an anatomically accurate, functional flow loop phantom of a patient's cardiac vasculature was used to assist in the surgical planning of one of the first native transcatheter mitral valve replacement (TMVR) procedures. CTA scans were acquired from a patient about to undergo the first minimally-invasive native TMVR procedure at the Gates Vascular Institute in Buffalo, NY. A python scripting library, the Vascular Modeling Toolkit (VMTK), was used to segment the 3D geometry of the patient's cardiac chambers and mitral valve with severe stenosis, calcific in nature. A stereolithographic (STL) mesh was generated and AutoDesk Meshmixer was used to transform the vascular surface into a functioning closed flow loop. A Stratasys Objet 500 Connex3 multi-material printer was used to fabricate the phantom with distinguishable material features of the vasculature and calcified valve. The interventional team performed a mock procedure on the phantom, embedding valve cages in the model and imaging the phantom with a Toshiba Infinix INFX-8000V 5-axis Carm bi-Plane angiography system. Results: After performing the mock-procedure on the cardiac phantom, the cardiologists optimized their transapical surgical approach. The mitral valve stenosis and calcification were clearly visible. The phantom was used to inform the sizing of the valve to be implanted. Conclusion: With advances in image processing and 3D printing technology, it is possible to create realistic patientspecific phantoms which can act as a guide for the interventional team. Using 3D printed phantoms as a valve sizing method shows potential as a more informative technique than typical CTA reconstruction alone.

    2005-02-01

    Full Text Available Abstract Background Bony defects arising from tumor resection or debridement after infection, non-union or trauma present a challenging problem to orthopedic surgeons, as well as patients due to compliance issues. Current treatment options are time intensive, require more than one operation and are associated with high rate of complications. For this reason, we developed a new surgical procedure to bridge a massive long bone defect. Methods To bridge the gap, an in situ periosteal sleeve is elevated circumferentially off of healthy diaphyseal bone adjacent to the bone defect. Then, the adjacent bone is osteotomized and the transport segment is moved along an intramedullary nail, out of the periosteal sleeve and into the original diaphyseal defect, where it is docked. Vascularity is maintained through retention of the soft tissue attachments to the in situ periosteal sleeve. In addition, periosteal osteogenesis can be augmented through utilization of cancellous bone graft or in situ cortical bone adherent to the periosteal sleeve. Results The proposed procedure is novel in that it exploits the osteogenic potential of the periosteum by replacing the defect arising from resection of tissue out of a pathological area with a defect in a healthy area of tissue, through transport of the adjacent bone segment. Furthermore, the proposed procedure has several advantages over the current standard of care including ease of implementation, rapid patient mobilization, and no need for specialized implants (intramedullary nails are standard inventory for surgical oncology and trauma departments or costly orthobiologics. Conclusions The proposed procedure offers a viable and potentially preferable alternative to the current standard treatment modalities, particularly in areas of the world where few surgeons are trained for procedures such as distraction osteogenesis (e.g. the Ilizarov procedure as well as areas of the world where surgeons have little access to

When used alone, it is incapable of producing general anesthesia reliably. However, as a single agent, it has an impressive safety and is excellent for providing minimal and moderate sedation for apprehensive minor oral surgical procedure. In this article, action of N 2 O in overcoming the anxiety and pain of the patient during the minor oral surgery and its advantages and disadvantages, have been reviewed.

  7. Estimation of skin dose in interventional neuro and cardiac procedures

    International Nuclear Information System (INIS)

    The dose thresholds for inducing deterministic effects such as erythema and epilation are now within the range of some interventional radiology procedures. It is important to identify those procedures where such dose levels are possible so that more detailed dosimetry and dose reduction can be introduced to minimise the risk of such effects. This paper presents results of work on anthropomorphic phantoms to establish a link between a commonly measured dose indicator (dose-area product) and skin dose, for equipment and geometries commonly used for cardiac and neurological interventional radiology procedures. The results indicate that a conversion to skin dose is equipment specific and furthermore depends on field size and projection. By auditing a sample set of patient data, however, it is possible to identify potentially high dose procedures. (author)

    Pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) have become life-saving therapeutic tools for patients with cardiac arrhythmia. Complications include thrombosis, embolism and infections at a highly variable rate. Surgical removal of the infected device has been perceived as the only way to guarantee a successful outcome and to reduce the high risk of mortality. Recently, a transvenous extraction method has been developed to remove infected intracardiac leads without sternotomy. This survey was designed to evaluate the outcome of an approach combining antibiotic therapy with non-surgical transvenous complete removal for the management of cardiac device infections (CDIs). We reviewed case-histories of 121 patients (105 with PM and 16 with ICD infections). The aim of our retrospective survey was to ascertain that a non-invasive transvenous complete removal of the infected devices is safe and effective when associated with appropriate antibiotic therapy starting 10 days before the procedure and extending to at least three weeks after. The infected devices were successfully removed in all patients with a non-surgical transvenous technique. The infections were most frequently caused by coagulase-negative staphylococci (70%), Staphylococcus aureus (14%), and Gram-negative rods (12%). Polymicrobial infections were documented in 19 patients and represent 16% of all device-related infections. The removal of the devices was done during antibiotic therapy, administered for a median of 26 days (range 23 to 45 days). Neither fatalities nor relapse of infections were recorded in the patient population during the one-year follow-up visits. According to our experience, CDIs can be treated with antibiotic therapy and non-surgical removal of the entire infected device, thus allowing a successful reimplantation. This procedure prevents recurrent infections and operative mortality. PMID:16736884

  9. Radiation Doses in Some Cardiac Catheterization and Angiography Procedures

    International Nuclear Information System (INIS)

    Interventional radiology involves diagnostic and therapeutic procedures that range from simple to complex. Patients can be subjected to varying radiation doses. The study aims to determine the variation in patient entrance doses of pediatric and adult patients who underwent selected cardiac catheterization and angiography procedures at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia. It is also aimed to investigate the methods for optimizing radiation protection. A total of 761 pediatric patients and 114 adult patients for cardiac catheterization and 320 adults for angiography were included in the study. Results showed that pulmonary and PDA are high dose procedures yielding to an average effective dose of 10 and 8.2 mSv respectively. DAP values showed a good correlation with effective doses for diagnostic and COA dilatation with r2 equal to 0.81 and 0.70 respectively. PTCA procedure delivered a maximum skin dose that exceeded the threshold dose for skin erythemia with a value of 4.5 Gy. Percutaneous Transhepatic Choleangiography (PTC) and Transjugular Intrahepatic Portosystemic Shunts (TIPSS) delivered the maximum skin dose of 983 and 735 mGy. The study recommends that a review of the protocols and setting of image quality criteria for pediatric especially for age groups 0 and 1 and adult patients should be made in order that fluoroscopy time , peak kilovoltage and number of cine series be reduced.

    2016-05-01

    Background Variability in case exposures has been identified for orthopaedic surgery residents. It is not known if this variability exists for peripheral nerve procedures. Objective The objective of this study was to assess ACGME case log data for graduating orthopaedic surgery, plastic surgery, general surgery, and neurological surgery residents for peripheral nerve surgical procedures and to evaluate intraspecialty and interspecialty variability in case volume. Methods Surgical case logs from 2009 to 2014 for the 4 specialties were compared for peripheral nerve surgery experience. Peripheral nerve case volume between specialties was performed utilizing a paired t test, 95% confidence intervals were calculated, and linear regression was calculated to assess the trends. Results The average number of peripheral nerve procedures performed per graduating resident was 54.2 for orthopaedic surgery residents, 62.8 for independent plastic surgery residents, 84.6 for integrated plastic surgery residents, 22.4 for neurological surgery residents, and 0.4 for surgery residents. Intraspecialty comparison of the 10th and 90th percentile peripheral nerve case volume in 2012 revealed remarkable variability in training. There was a 3.9-fold difference within orthopaedic surgery, a 5.0-fold difference within independent plastic surgery residents, an 8.8-fold difference for residents from integrated plastic surgery programs, and a 7.0-fold difference within the neurological surgery group. Conclusions There is interspecialty and intraspecialty variability in peripheral nerve surgery volume for orthopaedic, plastic, neurological, and general surgery residents. Caseload is not the sole determinant of training quality as mentorship, didactics, case breadth, and complexity play an important role in training. PMID:27168883

    Full Text Available Objective: Lymphedema is the result of impaired lymphatic drainage from the affected organ. This abnormality can be primary or secondary. Different nonoperative and operative approaches have been introduced to treat chronic lymphedema. In this study, we describe a new surgical technique and compare its results with other more commonplace methods. Methods:Fifty-nine patients with the diagnosis of chronic lower extremity lymphdema who had not responded to nonoperative management for at least 6 months, were included in the study. They were collected during 15 years between March 1987 and March 2002. Doppler ultrasonography of deep venous system to confirm its patency was routinely performed in the most of patients. Then, they underwent surgery and were followed for at least 1 year postoperatively. Findings: All the patients were operated by our new technique which is a modified form of the Homans. The outcome was excellent and 89.2% of patients were devoid of complication. A 10.8% total complication rate was inevitable. The most common complication was wound seroma. Conclusion: According to the difficulties with treatment of chronic lymphedema and variety of surgical options, our method can be an excellent and even the standard operative procedure to treat intractable forms of disease.

  16. Optimization of radiation protection in pediatric cardiac catheterization procedures

    International Nuclear Information System (INIS)

    Cardiac catheterization is among the interventional radiology procedures considered to give high doses to adult and pediatric patients. However, almost every year, the number of pediatric patients undergoing these procedures tends to increase. The King Faisal Specialist Hospital and Research Centre (KFSH and RC) is a tertiary level medical center in Riyadh, Kingdom of Saudi Arabia with a 600 bed capacity. Diagnostic X ray procedures (radiography and fluoroscopy) average to about 150,000 annually. Pediatric cardiac catheterization procedures average to about 2,000 cases annually. Due to the limited published data on radiation doses to pediatric patients undergoing these procedures, a study was conducted to assess the doses in pediatric patient undergoing cardiac catheterization procedures and to determine the factors contributing to high doses. Patient and occupational doses during interventional procedures depend on procedure type, fluoroscopy time, number of images, equipment performance and training of the interventionist. KFSH and RC has four X ray rooms in its Cardiac Catheterization Laboratory. There is only one X ray room that is dedicated for pediatric procedure and it was selected for the study. This room is equipped with a Siemens Bicor + biplane X ray unit with HVL of 3.5 mm Al each for the two X ray tubes. The equipment geometry allows the system to have X ray beams in the vertical, horizontal and oblique directions. The system has a built-in DAP meter. Data on quality control tests and DAP calibration performed by the in-house biomedical engineer of Siemens was retrieved. The DAP calibration data supplied by the engineer were verified using a Diamentor M1 (PTW, Freiburg, Germany) DAP meter and following the NRPB protocol. Results of the quality control tests on the X ray machine generator were investigated. The dose area product values from records of pediatric patients in the age groups of 0 (neonates), 1, 5 and 10 years on four common procedures were

    International Nuclear Information System (INIS)

    The aim of this study was to assess effective dose to a patient during cardiac procedures, such as coronary angiography (CA) and percutaneous transluminal angioplasty (PTCA). Measurements were performed on 185 patients in four catheterisation laboratories in three hospitals in Prague using the dose area product (DAP) meter. Calculations of surface and effective dose were performed with Monte-Carlo-based program PCXMC. The mean DAP value per procedure determined in all workplaces ranged between 25.0 and 54.5 Gy cm2 for CA and 43.0-104.5 Gy cm2 for PTCA. In three cases, the surface dose exceeded the 2 Gy level for occurrence of transient erythema. The mean effective dose per procedure in an workplaces was determined to be in the range of 2.7-8.8 mSv for CA and 5.7-15.3 mSv for CA + PTCA combined. The results presented are comparable with those published by other authors. (authors)

  19. Soft Tissue Surgical Procedures for Optimizing Anterior Implant Esthetics

    2015-01-01

    Full Text Available Implant dentistry has been established as a predictable treatment with excellent clinical success to replace missing or nonrestorable teeth. A successful esthetic implant reconstruction is predicated on two fundamental components: the reproduction of the natural tooth characteristics on the implant crown and the establishment of soft tissue housing that will simulate a healthy periodontium. In order for an implant to optimally rehabilitate esthetics, the peri-implant soft tissues must be preserved and/or augmented by means of periodontal surgical procedures. Clinicians who practice implant dentistry should strive to achieve an esthetically successful outcome beyond just osseointegration. Knowledge of a variety of available techniques and proper treatment planning enables the clinician to meet the ever-increasing esthetic demands as requested by patients. The purpose of this paper is to enhance the implant surgeon’s rationale and techniques beyond that of simply placing a functional restoration in an edentulous site to a level whereby an implant-supported restoration is placed in reconstructed soft tissue, so the site is indiscernible from a natural tooth.

  20. Cosmetics for the eye area after cosmetic surgical procedures.

    Cosmetic enhancement of the eye area after esthetic surgery allows the patient to get back into the mainstream of life faster. It also improves their psychic state by blocking out discoloration, helping to disguise incision scars and artistically coloring the face to enhance the results of the surgery. The patients automatically feel better, when they look better. After a surgical procedure, there are temporary and permanent structural changes that appear with blepharoplasty and laser surgery. Although these surgeries will take away loose skin, puffy fat deposits and wrinkles, they do not change the bone structure or eye placement. Before starting a makeup application, analyzation of the eyes for their structural features help the artist know the value of colors to be used. The measuring points of the brow along with the importance of framing the eye will also be discussed. Once the brows and the eyes have been analyzed, the artist needs to take into consideration the personality of the patient. This helps the artist decide on the colors, value, intensity and design which will be applied to the patient. Before eye makeup can be applied, the use of primers, concealers and/or camouflage creams will be used to block out any discoloration in the eye area. We will look at concerns in formulation of products that will go around the eyes after surgery. The application of cosmetic products should be used as an accessory. Women have a variety of dress styles: casual, business or evening. The style of makeup application should work in conjunction with what they are wearing and how they are feeling at the time. Just as there are many facets to a woman, there are various styles of application to fit her personality. PMID:10393519

    A 9-year-old boy with congenital atresia of the left main coronary artery underwent myocardial revascularization. Coarctation of the aorta and ventricular septal defect were diagnosed at the age of 1 year. At age 7 years, the child presented with syncope while exercising. Preoperative evaluation included cardiac catheterization which revealed the unexpected finding of congenital atresia of the left main coronary artery with origin of the circumflex artery from the right coronary artery. Surgical correction included myocardial revascularization by means of left internal mammary artery graft to the anterior descending coronary artery, coarctation resection, and ventricular septal defect repair. The patient recovered uneventfully. We report the details of this extremely rare case with successful concomitant surgical management of the congenital coronary artery anomaly and the associated structural heart disease. PMID:23804483

Surgical indications including obstruction due to strictures or adhesions, fistulae and abscesses, and surgeries for these conditions, such as, ileocecectomy, stricturoplasty, small bowel resection, fecal diversion, segmental colectomy, and lysis of adhesions and their complications will be discussed and their imaging will also be illustrated.

  6. The Evolving Utility of Intracardiac Echocardiography in Cardiac Procedures

    Directory of Open Access Journals (Sweden)

    Dr. Christopher F. Liu

    2014-04-01

    Full Text Available Intracardiac echocardiography (ICE has gained increasing use in electrophysiology due to the need to visualize key anatomic structures. Precise guidance for transseptal puncture and visualization of the pulmonary veins are common essential uses for ICE, but many operators adept at ICE imaging have developed additional and specific uses. With heavy use of ICE guidance, electrophysiologists demonstrated feasibility of left atrial ablation with minimal use of fluoroscopy. With the advent of 3D mapping-integrated ICE, rendering of contours for the left atrium, aortic cusps, and left ventricular structures such as the papillary muscles have become possible. Improved understanding of the anatomy of these areas can facilitate mapping and ablation of these structurally complex sites. Additional uses of scar-visualization and integration into voltage maps have been explored. Left atrial appendage imaging has been an area of interest in the ICE community, although technological improvements are likely needed to make this more reliably complete. A new real-time 3D ICE catheter has also been developed, and work is in progress to delineate potential uses for this new frontier. Increasingly routine use of ICE has led to improved real-time guidance of all percutaneous cardiac procedures.

  7. Rheumatic heart disease- a study of surgically excised cardiac valves and biopsies

    International Nuclear Information System (INIS)

    Objective: To examine the prevalence, age, sex and topographical distribution of the rheumatic heart diseases and its morphology. Design: A cross sectional descriptive study. Place and Duration of Study: Pathology Department, Army Medical College, Rawalpindi between 1981-1990. Patients and Methods: Five hundred and twenty six surgically excised cardiac valves and biopsies were studied in the laboratory in the light of clinical data. Results: Carditis constituted 87.4 % of the cardiac valvular disease with 23.5% active and 71% healed rheumatic lesions. About 5.5% had morphological appearances consistent with RHD. The lesions affected mitral valves (37.0%), aortic valve (22.1%), mitral and aortic valves together (21.0%) and atrial appendages (19.0%). Presentation was mostly as mitral stenosis either isolated (49.2% ) or combined (31.0%), aortic stenosis (11.7% ) and aortic incompetence with regurgitation (7.3%). Conclusion: Rheumatic carditis constitutes a significant proportion of cardiac valvular disease and affects comparatively younger age, with slight male preponderance and primarily affects mitral valve.

    Full Text Available The special importance of the surgeon's hand in the multi-barrier concept to prevent surgical site infections is based on two facts: the resident flora on the hands cannot be totally eradicated and the surgical glove is no reliable barrier for micro-organisms. The aim of the pre-surgical disinfection is therefore to eliminate the transient flora and reduce the resident flora to the greatest possible amount for the duration of the surgery. New experimental evidence has led to changes in the pre-surgical disinfection. The article summarises the actual knowledge and practice of the pre-surgical disinfection with special focus on pre-conditions for hand disinfection, requirements on the efficacy and the influence on a previous hand wash, duration of disinfection and practical implementation. Because some countries still prefer scrubs to alcoholic rubs, we compare both methods based on efficacy, compliance and dermal tolerance with the conclusion that rubs are superior to scrubs in all evaluated categories.

    Introduction Chronic pancreatitis (CP) can be a cause of recurrent, severe, disabling abdominal pain in children. Surgery has been suggested as a useful therapy, although experience is limited and the results unpredictable. We reviewed our experience of a two-stage protocol-preliminary endoscopic retrograde cholangiopancreatography (ERCP) and duct stenting, and if symptoms resolved, definitive surgical decompression by longitudinal pancreatojejunostomy (LPJ) (Puestow operation). Patients and Methods This is a single-center, retrospective review of children with established CP who underwent an LPJ between February 2002 and September 2012. A questionnaire was completed (incorporating visual analog scale pain and lifestyle scores) to assess functional outcome. Data are expressed as median (range). Results In this study, eight (M:F ratio of 4:4) children underwent an LPJ and one female child had a more limited pancreatojejunostomy anastomosis following preliminary ERCP and stent placement where possible. Diagnoses included hereditary pancreatitis (n = 3), idiopathic or structural pancreatitis (n = 5), and duct stricture following radiotherapy (n = 1). Median duct diameter presurgery was 5 (4-11) mm. Endoscopic placement of a Zimmon pancreatic stent was possible in six with relief of symptoms in all. Median age at definitive surgery was 11 (range, 7-17) years with a median postoperative stay of 9 (range, 7-12) days and a follow-up of 6 (range, 0.5-12) years. All children reported markedly reduced episodes of pain postprocedure. One developed diabetes mellitus, while three had exocrine deficiency (fecal elastase < 200 µg/g) requiring enzyme supplementation. The child with limited LPJ had symptomatic recurrence and required restenting and further surgery to widen the anastomosis to become pain free. Conclusion ERCP and stenting provide a therapeutic trial to assess possible benefit of a definitive duct drainage procedure. LPJ-the modified Puestow

  10. Monitoring radiation use in cardiac fluoroscopy imaging procedures

    International Nuclear Information System (INIS)

    Purpose: Timely identification of systematic changes in radiation delivery of an imaging system can lead to a reduction in risk for the patients involved. However, existing quality assurance programs involving the routine testing of equipment performance using phantoms are limited in their ability to effectively carry out this task. To address this issue, the authors propose the implementation of an ongoing monitoring process that utilizes procedural data to identify unexpected large or small radiation exposures for individual patients, as well as to detect persistent changes in the radiation output of imaging platforms. Methods: Data used in this study were obtained from records routinely collected during procedures performed in the cardiac catheterization imaging facility at St. Andrew's War Memorial Hospital, Brisbane, Australia, over the period January 2008-March 2010. A two stage monitoring process employing individual and exponentially weighted moving average (EWMA) control charts was developed and used to identify unexpectedly high or low radiation exposure levels for individual patients, as well as detect persistent changes in the radiation output delivered by the imaging systems. To increase sensitivity of the charts, we account for variation in dose area product (DAP) values due to other measured factors (patient weight, fluoroscopy time, and digital acquisition frame count) using multiple linear regression. Control charts are then constructed using the residual values from this linear regression. The proposed monitoring process was evaluated using simulation to model the performance of the process under known conditions. Results: Retrospective application of this technique to actual clinical data identified a number of cases in which the DAP result could be considered unexpected. Most of these, upon review, were attributed to data entry errors. The charts monitoring the overall system radiation output trends demonstrated changes in equipment performance

    To attract the interest of all people potentially involved in humanitarian activities in the emerging economies, in particular giving attention to the basic requirements of the organization of paediatric cardiac surgery activities, the requirements for a successful partnership with the local existing organizations and the basic elements of a patient-centred multidisciplinary integrated approach. Unfortunately, for many years, the interventions in the low and middle income countries were largely limited to short-term medical missions, not inappropriately nicknamed 'surgical safari', because of negative general and specific characteristics. The negative aspects and the limits of the short-term medical missions can be overcome only by long-term educational programmes. The most suitable and consistent models of long-term educational programmes have been combined and implemented with the personal experience to offer a proposal for a long-term educational project, with the following steps: (i) site selection; (ii) demographic research; (iii) site assessment; (iv) organization of surgical educational teams; (v) regular frequency of surgical educational missions; (vi) programme evolution and maturation; (vii) educational outreach and interactive support. Potential limits of a long-term educational surgical programme are: (i) financial affordability; (ii) basic legal needs; (iii) legal support; (iv) non-profit indemnification. The success should not be measured by the number of successful operations of any given mission, but by the successful operations that our colleagues perform after we leave. Considering that the children in need outnumber by far the people able to provide care, in this humanitarian medicine there should be plenty of room for cooperation rather than competition. The main goal should be to provide teaching to local staff and implement methods and techniques to support the improvement of the care of the patients in the long run. This review focuses on the

  15. Artificial aortic valve dysfunction due to pannus and thrombus – different methods of cardiac surgical management

    2015-01-01

    Introduction Approximately 60 000 prosthetic valves are implanted annually in the USA. The risk of prosthesis dysfunction ranges from 0.1% to 4% per year. Prosthesis valve dysfunction is usually caused by a thrombus obstructing the prosthetic discs. However, 10% of prosthetic valves are dysfunctional due to pannus formation, and 12% of prostheses are damaged by both fibrinous and thrombotic components. The authors present two patients with dysfunctional aortic prostheses who were referred for cardiac surgery. Different surgical solutions were used in the treatment of each case. Case study 1 The first patient was a 71-year-old woman whose medical history included arterial hypertension, stable coronary artery disease, diabetes mellitus, chronic obstructive pulmonary disease (COPD), and hypercholesterolemia; she had previously undergone left-sided mastectomy and radiotherapy. The patient was admitted to the Cardiac Surgery Department due to aortic prosthesis dysfunction. Transthoracic echocardiography revealed complete obstruction of one disc and a severe reduction in the mobility of the second. The mean transvalvular gradient was very high. During the operation, pannus covering the discs’ surface was found. A biological aortic prosthesis was reimplanted without complications. Case study 2 The second patient was an 87-year-old woman with arterial hypertension, persistent atrial fibrillation, and COPD, whose past medical history included gastric ulcer disease and ischemic stroke. As in the case of the first patient, she was admitted due to valvular prosthesis dysfunction. Preoperative transthoracic echocardiography revealed an obstruction of the posterior prosthetic disc and significant aortic regurgitation. Transesophageal echocardiography and fluoroscopy confirmed the prosthetic dysfunction. During the operation, a thrombus growing around a minor pannus was found. The thrombus and pannus were removed, and normal functionality of the prosthetic valve was restored

    We report herein a case of benign cardiac schwannoma in the interatrial septum. A 42-year-old woman was transferred from a clinic because of cardiomegaly as determined by chest X-ray. A transthoracic echocardiography and chest computed tomography examination revealed a huge mass in the pericardium compressing the right atrium, superior vena cava (SVC), left atrium, and superior pulmonary vein. To confirm that the tumor originated from either heart or mediastinum, cine magnetic resonance imaging was performed, but the result was not conclusive. To facilitate surgical planning, we used 3D printing. Using a printed heart model, we decided that tumor resection under cardiopulmonary bypass (CPB) through sternotomy would be technically feasible. At surgery, a huge tumor in the interatrial septum was confirmed. By incision on the atrial roof between the aorta and SVC, tumor enucleation was performed successfully under CPB. Pathology revealed benign schwannoma. The patient was discharged without complication. 3D printing of the heart and tumor was found to be helpful when deciding optimal surgical approach.

    2012-01-01

    Full Text Available The popularity of day case surgical procedures has increased immensely over the last few years. Though various techniques are available for carrying out day-case anesthesia, preference for a technique depends upon the type of procedure, patient profile, associated co-morbidities, available infrastructure and back-up facilities, monitoring devices and comfort of the attending anesthesiologist with the technique. Day-case spinal anesthesia for ambulatory surgery has gained a wider acceptance and numerous drugs are available for use in loco-regional anesthesia. Articaine is one such amide local anesthetic drug which is increasingly being used in day care surgeries. Properties of articaine such as faster onset, shorter elimination time and rapid recovery from sensory and motor blockade make it a very useful agent in local and regional anesthesia for day care surgical procedures. This article aims to review these properties of articaine so as to evaluate how useful articaine can be for ambulatory surgical procedures.

    2012-01-01

    Full Text Available Surgical crown lengthening has been proposed as a means of facilitating restorative procedures and preventing injuries in teeth with structurally inadequate clinical crown or exposing tooth structure in the presence of deep, subgingival pathologies which may hamper the access for proper restorative measures. Histological studies utilizing animal models have shown that postoperative crestal resorption allowed reestablishment of the biologic width. However, very little has been done in humans. Aims. The purpose of the study was to evaluate the potential changes in the periodontal tissues, particularly the biologic width, following surgical crown lengthening by two surgical procedures before and after crown placement. Methods and Material. Twenty (20 patients who needed surgical crown lengthening to gain retention necessary for prosthetic treatment and/or to access caries, tooth fracture, or previous prosthetic margins entered the study. The following parameters were obtained from line angles of treated teeth (teeth requiring surgical crown lengthening and adjacent sites: Plaque and Gingival Indices (PI & (GI, Position of Gingival Margin from reference Stent (PGMRS, Probing depth (PD, and Biologic Width (BW. Statistical Analysis Used. Student “t” Test. Results. Initial baseline values of biologic width were 2.55 mm (Gingivectomy procedure B1 Group and 1.95 mm (Ostectomy procedure B2 Group and after surgical procedure the values were 1.15 mm and 1.25 mm. Conclusions. Within the limitations of the study the biologic width, at treated sites, was re-established to its original vertical dimension by 3 months. Ostectomy with apically positioned flap can be considered as a more effective procedure than Gingivectomy for Surgical Crown Lengthening.

    2013-01-01

    Full Text Available Introduction: Orthodontic treatment is based on the principle that if prolonged pressure is applied to the tooth, tooth movement will occur as the bone around the tooth re-models. In this study osteotomy of buccal alveolar plate and undermining of interseptal bone was performed at premolar extraction site and rate of en-masse retraction and canine retraction was evaluated. Materials and Methods: Patients between the age of 18 and 25 years, requiring retraction of anterior teeth are selected for the study. Osteotomy with undermining of interseptal bone at the extraction site was performed. The procedure was performed on all four quadrants. Results: The average retraction in the maxillary arch was 0.98 mm/quadrant in 3 weeks, i.e., a total retraction of 5.89 mm in a span of 9 weeks. The average retraction in the mandibular arch was 0.96 mm/quadrant in 3 weeks, i.e., a total retraction of 5.75 mm in a span of 9 weeks. Conclusion: This method of achieving faster en masse retraction immediately after extraction definitely reduced the initial retraction time. We recommend that such procedure must be carried out with appropriate anchorage conservation methods.

    Neoplastic disease is common in pet birds, particularly in psittacines, and treatment should be primarily aimed at tumor eradication. Nineteen cases of pet birds submitted to diagnostic and/or therapeutic surgical procedures due to neoplastic disease characterized by the presence of visible masses were retrospectively analyzed; affected species, types of neoplasms and respective locations, and outcomes of surgical procedures were determined. All birds undergoing surgery belonged to the order Psittaciformes; the Blue-fronted parrot (Amazona aestiva) was the prevalent species. Lipoma was the most frequent neoplasm in the sample studied. Most neoplasms affected the integumentary system, particularly the pericloacal area. Tumor resection was the most common surgical procedure performed, with high resolution and low recurrence rates.

All birds undergoing surgery belonged to the order Psittaciformes; the Blue-fronted parrot (Amazona aestiva) was the prevalent species. Lipoma was the most frequent neoplasm in the sample studied. Most neoplasms affected the integumentary system, particularly the pericloacal area. Tumor resection was the most common surgical procedure performed, with high resolution and low recurrence rates.

    Full Text Available Background: Identifying infections early, commencing appropriate empiric antibiotic not only helps gain control early, but also reduces mortality and morbidity. Conventional cultures take about 5 days to identify infections. To identify the infections early biomarker like serum procalcitonin (SPC. Aims: We studied the correlation of an elevated level of SPC and positive culture in elective adult patients undergoing cardiac surgery. Methods: This prospective study was conducted from January to December 2013. SPC was checked in patients showing evidence of sepsis. Simultaneously, relevant culture was also undertaken. Correlation, specificity, and sensitivity of elevated SPC were checked. Results: A total of 819 adult patients were included in the study. 43 of them had signs of infection and SPC levels were checked. Based on the level of SPC criteria, 10 patients were diagnosed as "nil", out of them, 4 had culture-positive infections, 17 were suggested to have "mild infection," 3 out those had culture positivity. None among the eleven patients suggested to have "moderate infection," had a positive culture, and one among the five suggested to have a severe infection had a positive culture. The sensitivity was 50% and the specificity 17%. The positive predictive value was 12% and the negative predictive value 60%. Conclusions: We failed to elicit positive correlation between elevated SPC levels and postoperative infection in cardio surgical patients.

    Full Text Available Abstract Background The perioperative use of high inspired oxygen fraction (FIO2 for preventing surgical site infections (SSIs has demonstrated a reduction in their incidence in some types of surgery however there exist some discrepancies in this respect. The aim of this study was to analyze the relationship between PaO2 values and SSIs in cardiac patients. Methods We designed a prospective study in which 1,024 patients undergoing cardiac surgery were analyzed. Results SSIs were observed in 5.3% of patients. There was not significant difference in mortality at 30 days between patients with and without SSIs. In the uni and multivariate analysis no differences in function of the inspired oxygen fraction administrated were observed. Conclusions We observed that the PaO2 in adult cardiac surgery patients was not related to SSI rate.

    2012-02-01

    There have been many changes in healthcare provision in recent years, including the delivery of some surgical services in primary care or in day surgery centres, which were previously provided by acute hospitals. Developments in the fields of interventional radiology and cardiology have further expanded the range and complexity of procedures undertaken in these settings. In the face of these changes there is a need to define from an infection prevention and control perspective the basic physical requirements for facilities in which such surgical procedures may be carried out. Under the auspices of the Healthcare Infection Society, we have developed the following recommendations for those designing new facilities or upgrading existing facilities. These draw upon best practice, available evidence, other guidelines where appropriate, and expert consensus to provide sensible and feasible advice. An attempt is also made to define minimal access interventions and minor surgical procedures. For minimal access interventions, including interventional radiology, new facilities should be mechanically ventilated to achieve 15 air changes per hour but natural ventilation is satisfactory for minor procedures. All procedures should involve a checklist and operators should be appropriately trained. There is also a need for prospective surveillance to accurately determine the post-procedure infection rate. Finally, there is a requirement for appropriate applied research to develop the evidence base required to support subsequent iterations of this guidance.

    2011-01-01

    Full Text Available Background: The cardiopulmonary bypass (CPB-associated atelectasis accounted for most of the marked post-CPB increase in shunt and hypoxemia. We hypothesized that pressure-regulated volume-control (PRVC modes having a distinct theoretical advantage over pressure-controlled ventilation (PCV by providing the target tidal volume at the minimum available pressure may prove advantageous while ventilating these atelactic lungs. Methods: In this prospective study, 36 post-cardiac surgical patients with a PaO 2 /FiO 2 (arterial oxygen tension/Fractional inspired oxygen < 300 after arrival to intensive care unit (ICU, (n = 34 were randomized to receive either PRVC or PCV. Air way pressure (Paw and arterial blood gases (ABG were measured at four time points [T1: After induction of anesthesia, T2: after CPB (in the ICU, T3: 1 h after intervention mode, T4: 1 h after T3]. Oxygenation index (OI = [PaO 2 / {FiO 2 × mean airway pressure (Pmean }] was calculated for each set of data and used as an indirect estimation for intrapulmonary shunt. Results: There is a steady and significant improvement in OI in both the groups at first hour [PCV, 27.5(3.6 to 43.0(7.5; PRVC, 26.7(2.8 to 47.6(8.2 (P = 0.001] and second hour [PCV, 53.8(6.4; PRVC, 65.8(7.4 (P = 0.001] of ventilation. However, the improvement in OI was more marked in PRVC at second hour of ventilation owing to significant low mean air way pressure compared to the PCV group [PCV, 8.6(0.8; PRVC, 7.7(0.5, P = 0.001]. Conclusions: PRVC may be useful in a certain group of patients to reduce intrapulmonary shunt and improve oxygenation after cardiopulmonary bypass-induced perfusion mismatch.

  13. Reference levels at European level for cardiac interventional procedures

    International Nuclear Information System (INIS)

    In interventional cardiology, a wide variation in patient dose for the same type of procedure has been recognised by different studies. Variation is almost due to procedure complexity, equipment performance, procedure protocol and operator skill. The SENTINEL consortium has performed a survey in nine european centres collecting information on near 2000 procedures, and a new set of reference levels (RLs) for coronary angiography and angioplasty and diagnostic electrophysiology has been assessed for air kerma-area product: 45, 85 and 35 Gy cm2, effective dose: 8, 15 and 6 mSv, cumulative dose at interventional reference point: 650 and 1500 mGy, fluoroscopy time: 6.5, 15.5 and 21 min and cine frames: 700 and 1000 images, respectively. Because equipment performance and set-up are the factors contributing to patient dose variability, entrance surface air kerma for fluoroscopy, 13 mGy min-1, and image acquisition, 0.10 mGy per frame, have also been proposed in the set of RLs.

  17. Ten Years Experiences With Preoperative Evaluation Clinic for Day Admission Cardiac and Major Vascular Surgical Patients: Model for "Perioperative Anesthesia and Surgical Home".

    Science.gov (United States)

    Silvay, George; Zafirova, Zdravka

    2016-06-01

    Admission on the day of surgery for elective cardiac and noncardiac surgery is the prevalent practice in North America and Canada. This approach realizes medical, psychological and logistical benefits, and its success is predicated on an effective outpatient preoperative evaluation. The establishment of a highly functional preoperative clinic with a comprehensive set up and efficient logistical pathways is invaluable. This notion in recent years has included the entire perioperative period, and the concept of a perioperative anesthesia/surgical home (PASH) is gaining popularity. The anesthesiologists as perioperative physicians can organize and lead the entire process from the preoperative evaluation, through the hosptial discharge. The functions of the PASH include preoperative optimization of medical conditions and psychological preparation of the patients and their support system; the care in the operating room and intensive care unit; pain management; respiratory therapy; cardiac rehabilitation; and specialized nutrition. Along with oversight of the medical issues, the preoperative visit is an opportune time for counseling, clarification of expectations and discussion of research, as well as for utilization of various informatics systems to consolidate the pertinent information and distribute it to relevant health care providers. We review the scientific foundation and practical applications of a preoperative visit and share our experience with the development of the preoperative evaluation clinic, designed specifically for cardiac and major vascular patients scheduled for day admission surgery. The ultimate goal of preoperative evaluation clinic is to ensure a safe, efficient, and cost-effective perioperative care for patients undergoing a complex type of surgery. PMID:26620138

  18. Surgical procedures performed in the neonatal intensive care unit on critically ill neonates: feasibility and safety

    International Nuclear Information System (INIS)

    Transferring unstable, ill neonates to and from the operating rooms carries significant risks and can lead to morbidity. We report on our experience in performing certain procedures in critically ill neonates in the neonatal intensive care unit (NICU). We examined the feasibility and safety for such an approach. All surgical procedures performed in the NICU between January 1999 and December 2005 were analyzed in terms of demographic data, diagnosis, preoperative stability of the patient, procedures performed, complications and outcome. Operations were performed at beside in the NICU in critically ill, unstable neonates who needed emergency surgery, in neonates of low birth weight (<1000 gm) and in neonates on special equipments like higher frequency ventilators and nitrous oxide. Thirty-seven surgical procedures were performed including 12 laparotomies, bowel resection and stomies, 7 repairs of congenital diaphragmatic hernias, 4 ligations of patent ductus arteriosus and various others. Birth weights ranged between 850 gm and 3500 gm (mean 2000 gm). Gestational age ranged between 25 to 42 weeks (mean, 33 weeks). Age at surgery was between 1 to 30 days (mean, 30 days). Preoperatively, 19 patients (51.3%) were on inotropic support and all were intubated and mechanically ventilated. There was no mortality related to surgical procedures. Postoperatively, one patient developed wound infection and disruption. Performing major surgical procedures in the NICU is both feasible and safe. It is useful in very low birth weight, critically ill neonates who have definite risk attached to transfer to the operating room. No special area is needed in the NICU to perform complication-free surgery, but designing an operating room within the NICU will be ideal. (author)

  19. Surgical reconstruction of pressure ulcer defects: a single- or two-stage procedure?

    LENUS (Irish Health Repository)

    Laing, Tereze A

    2012-02-01

    BACKGROUND: The surgical management of pressure ulcers traditionally involved staged procedures, with initial debridement of necrotic or infected material followed by reconstruction at a later date when the wound was deemed viable and free of gross infection. However, over the past decade, it has been suggested that a single-stage procedure, combining initial debridement and definitive reconstruction, may provide advantages over staged surgery. We present our experience with the staged approach and review the current evidence for both methods. SUBJECTS AND SETTINGS: : We reviewed medical records of all patients referred to our service for pressure ulcer management between October 2001 and October 2007. The National Rehabilitation Hospital is the national center in Ireland for primary rehabilitation of adults and children suffering from spinal and brain injury, serving patients locally and from around the country. METHODS: All subjects who were managed surgically underwent a 2-stage procedure, with initial debridement and subsequent reconstruction. The main outcome measures were length of hospital stay, postoperative morbidity and mortality, and time to complete ulcer healing. RESULTS: Forty-one of 108 patients with 58 pressure ulcers were managed surgically. All patients underwent initial surgical debridement and 20 patients underwent subsequent pressure ulcer reconstruction. Postreconstructive complications occurred in 5 patients (20%). The mean time to complete ulcer healing was 17.4 weeks. Partial flap necrosis occurred in 3 patients, but there were no episodes of flap failure. CONCLUSIONS: We achieved favorable results with a 2-stage reconstruction technique and suggest that the paucity of evidence related to single-stage procedures does not support a change in surgical management.

    The extensor apparatus is a complex muscle-tendon system that requires integrity or optimal reconstruction to preserve hand function. Anatomical knowledge and the understanding of physiopathology of extensor tendons are essential for an accurate diagnosis of extensor tendon injuries (ETIs) of the hand and wrist, because these lesions are complex and commonly observed in clinical practice. A careful clinical history and assessment still remain the first step for the diagnosis, followed by US and MR to confirm the suspect of ETI or to investigate some doubtful conditions and rule out associate lesions. During last decades the evolution of surgical techniques and rehabilitative treatment protocol led to gradual improvement in clinical results of ETI treatment and surgical repair. Injury classification into anatomical zones and the evaluation of the characteristics of the lesions are considered key points to select the appropriate treatment for ETI. Both conservative and surgical management can be indicated in ETI, depending on the anatomical zone and on the characteristics of the injuries. As a general rule, an attempt of conservative treatment should be performed when the lesion is expected to have favorable result with nonoperative procedure. Many surgical techniques have been proposed over the time and with favorable results if the tendon injury is not underestimated and adequately treated. Despite recent research findings, a lack of evidence-based knowledge is still observed in surgical treatment and postoperative management of ETI. Further clinical and biomechanical investigations would be advisable to clarify this complex issue. PMID:27616821

HEMOPATCH (Sealing Hemostat is a novel, advanced hemostatic pad that is composed of a synthetic, protein-reactive monomer and a collagen backing. The active side is covered with a protein-reactive monomer: N-hydroxysuccinimide functionalized polyethylene glycol (NHS-PEG. NHS-PEG rapidly affixes the collagen pad to tissue to promote and maintain hemostasis. The combined action of the NHS-PEG and collagen is demonstrated to have benefit relative to other hemostatic agents in surgery and preclinical surgical models. This paper reviews the published investigations and case reports of the hemostatic efficacy of HEMOPATCH, wherein HEMOPATCH is demonstrated to be an effective, easy-to-use hemostatic agent in open and minimally invasive surgery of patients with thrombin- or platelet-induced coagulopathies.

    Twenty-three patients had a painful ilioinguinal and/or iliohypogastric nerve entrapment syndrome following common surgical procedures in the lower portion of the abdomen (appendectomy, repair of inguinal hernia, and gynecologic procedures through transverse incision). The diagnostic triad of nerve entrapment after operation comprises (1) typical burning or lancinating pain near the incision that radiates to the area supplied by the nerve, (2) clear evidence of impaired sensory perception of the nerve, and (3) pain relieved by infiltration with anesthetic for local effects at the site where the two nerves leave the internal oblique muscle. Surgical repair of the scar with resection of the compromised nerve is the most effective treatment. Sixteen patients became symptom free after neurectomy, seven still suffer chronic pain in the scar. PMID:7065874

    It is well established that emotions are organized around two motivational systems: the defensive and the appetitive. Individual differences are relevant factors in emotional reactions, making them more flexible and less stereotyped. There is evidence that health professionals have lower emotional reactivity when viewing scenes of situations involving pain. The objective of this study was to investigate whether the rating of pictures of surgical procedure depends on their personal/occupational relevance. Fifty-two female Nursing (health discipline) and forty-eight Social Work (social science discipline) students participated in the experiment, which consisted of the presentation of 105 images of different categories (e.g., neutral, food), including 25 images of surgical procedure. Volunteers judged each picture according to its valence (pleasantness) and arousal using the Self-Assessment Manikin scale (dimensional approach). Additionally, the participants chose the word that best described what they felt while viewing each image (discrete emotion perspective). The average valence score for surgical procedure pictures for the Nursing group (M = 4.57; SD = 1.02) was higher than the score for the Social Work group (M = 3.31; SD = 1.05), indicating that Nursing students classified those images as less unpleasant than the Social Work students did. Additionally, the majority of Nursing students (65.4%) chose "neutral" as the word that best described what they felt while viewing the pictures. In the Social Work group, disgust (54.2%) was the emotion that was most frequently chosen. The evaluation of emotional stimuli differed according to the groups' personal/occupational relevance: Nursing students judged pictures of surgical procedure as less unpleasant than the Social Work students did, possibly reflecting an emotional regulation skill or some type of habituation that is critically relevant to their future professional work.

    Excessive bleeding and allogeneic transfusion during adult post-cardiotomy venoarterial extracorporeal membrane oxygenation (ECMO) are potentially harmful and expensive. Balancing the inhibition of clotting and distinguishing surgical from non-surgical bleeding in post-operative period is difficult. The sensitivity of coagulation tests including Thromboelastography(®) (TEG) to predict chest tube drainage in the early hours of ECMO was examined with the use of receiver-operating characteristics (ROC). The results are useful to incorporate in clinical evidence-based algorithms to guide management decisions. In the eighth hour of ECMO, 26 of the 53 adult patients (49%) studied were identified as non-bleeders (less than 2.0 mL/kg/h). All had experienced various types of cardiac surgical procedures. Fifty-two percent were female and the group was 54 ± 19 (mean ± 1 SD) years old. The coagulation parameter threshold with the maximum sensitivity and specificity to predict non-bleeding at 8 hours on ECMO was the kaolin plus heparinase TEG maximum amplitude (KH-TEG MA) at a significant ROC threshold (t) > 50 mm. The activated partial thromboplastin time (aPTT) t 51°, and the kaolin activated clotting time (ACT) t < 148 seconds were sensitive predictors of non-bleeders. The whole-blood KH-TEG MA was superior to the plasma-based aPTT or International Normalization Ratio (INR) to predict bleeding in the eighth hour of ECMO. Using coagulation laboratory thresholds that predict non-bleeding can begin a process of identifying patients earlier that are likely to bleed. Awareness of these parameter thresholds may improve care through patient protection from unnecessary transfusion and prolonging the life of the ECMO circuit. An algorithm incorporating the ROC thresholds was created to help recognize surgical bleeding to minimize unnecessary transfusions. PMID:27578897

    Currently, minimally invasive cardiac surgery has found widespread use even in congenital heart surgery. The number of defects, which can be corrected through a small incision or totally endoscopic, is on the rise. Nowadays, surgeons can repair atrial septal defect, ventricular septal defect, patent ductus arteriosus and other congenital heart defects using minimally invasive techniques. In this paper, we report 21 cases of successful repair of supracardiac partial anomalous right upper and middle pulmonary venous connection, using the Warden procedure. It was performed in children through the right-sided midaxillary thoracotomy with direct cardiopulmonary bypass cannulation and induction of ventricular fibrillation. There were no operative or early postoperative deaths or complications. All patients were in sinus rhythm at discharge. According to echocardiography, there were no cases of early SVC or pulmonary veins narrowing. The Warden procedure can be performed safely and efficiently using the minimally invasive cardiac surgery. PMID:26541958

    Prolonged inspiratory to expiratory (I:E) ratio ventilation has been researched to reduce lung injury and improve oxygenation in surgical patients with one-lung ventilation (OLV) or carbon dioxide (CO2) pneumoperitoneum. We aimed to confirm the efficacy of the 1:1 equal ratio ventilation (ERV) compared with the 1:2 conventional ratio ventilation (CRV) during surgical procedures. Electronic databases, including PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, and Google Scholar were searched.Prospective interventional trials that assessed the effects of prolonged I:E ratio of 1:1 during surgical procedures. Adult patients undergoing OLV or CO2 pneumoperitoneum as specific interventions depending on surgical procedures. The included studies were examined with the Cochrane Collaboration's tool. The data regarding intraoperative oxygenation and respiratory mechanics were extracted, and then pooled with standardized mean difference (SMD) using the method of Hedges. Seven trials (498 total patients, 274 with ERV) were included. From overall analysis, ERV did not improve oxygenation at 20 or 30 minutes after specific interventions (SMD 0.193, 95% confidence interval (CI): -0.094 to 0.481, P = 0.188). From subgroup analyses, ERV provided significantly improved oxygenation only with laparoscopy (SMD 0.425, 95% CI: 0.167-0.682, P = 0.001). At 60 minutes after the specific interventions, ERV improved oxygenation significantly in the overall analysis (SMD 0.447, 95% CI: 0.209-0.685, P reduce the Ppeak and Pplat. PMID:27043700

    Full Text Available INTRODUCTION: Rupture of the pectoralis major muscle appears to be increasing in athletes. However, the optimal treatment strategy has not yet been established. OBJECTIVES: To compare the isokinetic shoulder performance after surgical treatment to that after non-surgical treatment for pectoralis major muscle rupture. METHODS: We assessed 33 pectoralis major muscle ruptures (18 treated non-surgically and 15 treated surgically. Horizontal abduction and adduction as well as external and internal rotation at 60 and 120 degrees/s were tested in both upper limbs. Peak torque, total work, contralateral deficiency, and the peak torque agonist-to-antagonist ratio were measured. RESULTS: Contralateral muscular deficiency did not differ between the surgical and non-surgical treatment modalities. However, the surgical group presented twice the number of athletes with clinically acceptable contralateral deficiency (<20% for internal rotators compared to the non-surgical group. The peak torque ratio between the external and internal rotator muscles revealed a similar deficit of the external rotation in both groups and on both sides (surgical, 61.60% and 57.80% and non-surgical, 62.06% and 54.06%, for the dominant and non-dominant sides, respectively. The peak torque ratio revealed that the horizontal adduction muscles on the injured side showed similar weakness in both groups (surgical, 86.27%; non-surgical, 98.61%. CONCLUSIONS: This study included the largest single series of athletes reported to date for this type of injury. A comparative analysis of muscular strength and balance showed no differences between the treatment modalities for pectoralis major muscle rupture. However, the number of significant clinical deficiencies was lower in the surgical group than in the non-surgical group, and both treatment modalities require greater attention to the rehabilitation process, especially for the recovery of muscle strength and balance.

    Surgical simulation increasingly appears to be an essential aspect of tomorrow's surgery. The development of a hepatic surgery simulator is an advanced concept calling for a new writing system which will transform the medical world: virtual reality. Virtual reality extends the perception of our five senses by representing more than the real state of things by the means of computer sciences and robotics. It consists of three concepts: immersion, navigation and interaction. Three reasons have led us to develop this simulator: the first is to provide the surgeon with a comprehensive visualisation of the organ. The second reason is to allow for planning and surgical simulation that could be compared with the detailed flight-plan for a commercial jet pilot. The third lies in the fact that virtual reality is an integrated part of the concept of computer assisted surgical procedure. The project consists of a sophisticated simulator which has to include five requirements: visual fidelity, interactivity, physical properties, physiological properties, sensory input and output. In this report we will describe how to get a realistic 3D model of the liver from bi-dimensional 2D medical images for anatomical and surgical training. The introduction of a tumor and the consequent planning and virtual resection is also described, as are force feedback and real-time interaction. PMID:9554121

    Full Text Available Background: Nosocomial infections (NIs in the postoperative period not only increase morbidity and mortality, but also impose a significant economic burden on the health care infrastructure. This retrospective study was undertaken to (a evaluate the incidence, characteristics, risk factors and outcomes of NIs and (b identify common microorganisms responsible for infection and their antibiotic resistance profile in our Cardiac Surgical Intensive Care Unit (CSICU. Patients and Methods: After ethics committee approval, the CSICU records of all patients who underwent cardiovascular surgery between January 2013 and December 2014 were reviewed retrospectively. The incidence of NI, distribution of NI sites, types of microorganisms and their antibiotic resistance, length of CSICU stay, and patient-outcome were determined. Results: Three hundred and nineteen of 6864 patients (4.6% developed NI after cardiac surgery. Lower respiratory tract infections (LRTIs accounted for most of the infections (44.2% followed by surgical-site infection (SSI, 11.6%, bloodstream infection (BSI, 7.5%, urinary tract infection (UTI, 6.9% and infections from combined sources (29.8%. Acinetobacter, Klebsiella, Escherichia coli, and Staphylococcus were the most frequent pathogens isolated in patients with LRTI, BSI, UTI, and SSI, respectively. The Gram-negative bacteria isolated from different sources were found to be highly resistant to commonly used antibiotics. Conclusion: The incidence of NI and sepsis-related mortality, in our CSICU, was 4.6% and 1.9%, respectively. Lower respiratory tract was the most common site of infection and Gram-negative bacilli, the most common pathogens after cardiac surgery. Antibiotic resistance was maximum with Acinetobacter spp.

    Objective: The purpose of this study was to evaluate compliance with guidelines in surgical prophylaxis (SP) procedures in Turkey. Materials and Methods: A point prevalence study involving 4 university, 5 education and research and 7 public hospitals was performed assessing compliance with guidelines for antibiotic use in SP. Compliance was based on the “Clinical Practice Guidelines for Antimicrobial Surgery (CPGAS) 2013” guideline. Results: Sixteen centers were included in the study, with 166 operations performed at these being evaluated. Parenteral antibiotic for SP was applied in 161 (96.9%) of these. Type of antibiotic was inappropriate in 66 (40.9%) cases and duration of use in 47 (29.1%). The main antibiotics used inappropriately in SP were ceftriaxone, glycopeptides and aminoglycosides. No significant difference was observed between secondary and tertiary hospitals in terms of inappropriate selection. Duration of prophylaxis was also incompatible with guideline recommendations in approximately half of surgical procedures performed in both secondary and tertiary hospitals, however statistical significance was observed between institutions in favor of tertiary hospitals. Conclusion: Antibiotics are to a considerable extent used in a manner incompatible with guidelines even in tertiary hospitals in Turkey. It must not be forgotten that several pre-, intra- and postoperative factors can be involved in the development of surgical site infections (SSI), and antibiotics are not the only option available for preventing these. A significant improvement can be achieved in prophylaxis with close observation, educational activities, collaboration with the surgical team and increasing compliance with guidelines. All health institutions must establish and apply their own SP consensus accompanied by the guidelines in order to achieve success in SP. PMID:27026760

    Sometimes, cardiac catheterisation and electrophysiological procedures, diagnostic and interventional, require an anaesthesiological support. The anaesthesiologist receives radiation doses depending on various factors, such as type of procedure and exposure modality, anaesthesiological technique, individual protective devices and operator experience. The aim of this study was to investigate the dose per procedure, the exposure inhomogeneity and the effective dose, E, of a senior anaesthesiologist in the haemodynamic laboratory of Ospedali Riuniti, Bergamo. The dose monitoring was routinely performed with sets of several thermoluminescent dosemeters and an electronic personal dosemeter. The study covered 300 consecutive procedures over 1 y. The anaesthesiologist wore a protective apron, a thyroid collar and glasses (0.5 mm lead-equivalent). PMID:25752757

  16. Update on dexmedetomidine: use in nonintubated patients requiring sedation for surgical procedures

    Full Text Available Mohanad Shukry, Jeffrey A MillerUniversity of Oklahoma Health Sciences Center, Department of Anesthesiology, Children’s Hospital of Oklahoma, Oklahoma City, OK, USAAbstract: Dexmedetomidine was introduced two decades ago as a sedative and supplement to sedation in the intensive care unit for patients whose trachea was intubated. However, since that time dexmedetomidine has been commonly used as a sedative and hypnotic for patients undergoing procedures without the need for tracheal intubation. This review focuses on the application of dexmedetomidine as a sedative and/or total anesthetic in patients undergoing procedures without the need for tracheal intubation. Dexmedetomidine was used for sedation in monitored anesthesia care (MAC, airway procedures including fiberoptic bronchoscopy, dental procedures, ophthalmological procedures, head and neck procedures, neurosurgery, and vascular surgery. Additionally, dexmedetomidine was used for the sedation of pediatric patients undergoing different type of procedures such as cardiac catheterization and magnetic resonance imaging. Dexmedetomidine loading dose ranged from 0.5 to 5 μg kg-1, and infusion dose ranged from 0.2 to 10 μg kg-1 h-1. Dexmedetomidine was administered in conjunction with local anesthesia and/or other sedatives. Ketamine was administered with dexmedetomidine and opposed its bradycardiac effects. Dexmedetomidine may by useful in patients needing sedation without tracheal intubation. The literature suggests potential use of dexmedetomidine solely or as an adjunctive agent to other sedation agents. Dexmedetomidine was especially useful when spontaneous breathing was essential such as in procedures on the airway, or when sudden awakening from sedation was required such as for cooperative clinical examination during craniotomies.Keywords: dexmedetomidine, sedation, nonintubated patients

  17. Fluoroscopy time during cardiac catheterization procedures using the radial and femoral routes

    International Nuclear Information System (INIS)

    Background: Use of trans-radial route for cardiac catheterization is on the rise but is associated with increased radiation exposure to the operator. Our aim was to compare the radiation exposure, by taking fluoroscopy time (FT) as a surrogate of radiation exposure, to the operator with femoral and radial routes. Methods: This prospective observational study was carried out at Army Cardiac Center Lahore from lst Jan to 1st June 2013. Mean fluoroscopy times via trans-radia (TR) and trans-femoral (TF) routes were compared. Procedure time was considered as time from sheath insertion to the finish of the diagnostic and interventional procedure. Descriptive statistics were used to explain the data. Chi square test was applied to compare qualitative variables between them. Results: A total of 1,110 diagnostic and PCI cases were performed out of which there were 850 diagnostic CA and 260 PCI cases. The mean procedure time and mean fluoroscopy time for TF-CA was 15.5 ± 5.5 minutes and 4.3 ± 3.2 minutes respectively in the current study while for TR-CA was 6.6 ± 4.1. For TF-PCI, mean procedure time was 42.3 ± 16.7 minutes, mean fluoroscopy time was 11.6 ± 7.7 minutes and for TR-PCI it was 55.3 ± 19.2 and 15.4 ± 12.1. Conclusion: Radial route for cardiac catheterization procedures is associated with longer fluoroscopy time leading to increased radiation exposure to the operator along with an increased use of contrast.

  18. Evaluation of radiation doses and dose conversion coefficients for pediatric cardiac catheterization procedures

    International Nuclear Information System (INIS)

    Pediatric cardiac catheterization covers both diagnostic and therapeutic procedures that range from simple to complex and can subject pediatric patients to varying radiation doses. There is limited information on radiation doses delivered by pediatric cardiac catheterization procedures and there is no recommended reference dose levels established yet. The study aims to determine the variation in patient radiation doses in terms of dose area product values and effective doses; determine factors that contribute to high doses to optimize protection; and determine the effective dose conversion coefficient. It is also aimed to provide data to help in the establishment of reference dose levels. A total of 761 pediatric patients belonging to age groups 0, 1, 5 and 10 years who undergo diagnostic and three selected therapeutic procedures at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia are included in the study. Therapeutic procedures include COA, PDA and pulmonary procedures. Fluoroscopy and cine radiography are used in all procedures. Patient demography (weight, age, gender and height), radiographic technique factors, fluoroscopy and cine time, frame rate, and dose area product values are taken from patients records. Results show that the kVp varies by ± 1 kVp between procedures and by ± 6 kVp between AP and oblique + lateral projection for all procedures. The mA for lateral and oblique is about 40-70% higher than for AP. Effective doses for each procedure are estimated from the DAP values. The mean DAP and effective dose per procedure are analyzed for correlation with patient equivalent cylindrical diameter, weight, fluoroscopy time and number of frames. Initial results show that age group 0 and 1 year old have the highest mean value for effective dose (11.3 and 13.8 mSv respectively) for pulmonary procedure. Pooling all ages for each procedure, the pulmonary and PDA procedures gave the highest mean values for effective dose (10 and 8.2 m

    2006-11-01

    Patients who have cerebrovascular disease and vascular insufficiency routinely have neurosurgical and nonneurosurgical procedures. Anesthetic priorities must provide a still bloodless operative field while maintaining cardiovascular stability and renal function. Patients who have symptoms or a history of cerebrovascular disease are at increased risk for stroke, cerebral hypoperfusion, and cerebral anoxia. Type of surgery and cardiovascular status are key concerns when considering neuroprotective strategies. Optimization of current condition is important for a good outcome; risks must be weighed against perceived benefits in protecting neurons. Anesthetic use and physiologic manipulations can reduce neurologic injury and assure safe and effective surgical care when cerebral hypoperfusion is a real and significant risk. PMID:16935193

Design: Case series study with retrospective analysis of prospectively collected nonrandomized data.Methods: Between 2008 and 2012, 64 patients underwent OPEN and 43 underwent HYBRID. Patient characteristics, technique success, clinical improvement, and procedure-related morbidity were reviewed and compared. Patency rates and limb salvages were analyzed and compared using Kaplan–Meier life tables. Cox regression analyses were used to assess the influence of various risk factors on primary patency.Results: HYBRID patients were older and presented with worse New York Heart Association function compared with OPEN patients. The increase in the ankle-brachial index and improvement of Ruthford category after procedures were equivalent between two groups, but HYBRID patients had shorter hospital length of stay (7.6±12.0 versus 15.5±17.3; P= 0.018 and less overall perioperative morbidity (12% versus 28%; P=0.042 compared with OPEN patients. No statistically significant difference in 36-month primary (47.1%±7.1% versus 50.1%±9.4%; P=0.418, assisted primary (57.0%±7.9% versus 62.4%±9.2%; P=0.517, or secondary (82.0%±6.8% versus 83.1%±7.3%; P=0.445 patency was seen between the two groups. Limb salvage rates of HYBRID vs OPEN at 3 years were similar (76.3%±9.3% versus 80.4%±8.2%; P=0.579. Critical limb ischemia was a negative predictor of long-term patency of patients in both the HYBRID and OPEN groups (P=0.012 and P<0.001, respectively, and the presence of diabetes and renal insufficiency were another two independent predictors

    Objective: This paper describes a text processing system designed to automate the manual data abstraction process in a quality improvement (QI) program. The Surgical Care and Outcomes Assessment Program (SCOAP) is a clinician-led, statewide performance benchmarking QI platform for surgical and interventional procedures. The data elements abstracted as part of this program cover a wide range of clinical information from patient medical history to details of surgical interventions. Methods: Statistical and rule-based extractors were developed to automatically abstract data elements. A preprocessing pipeline was created to chunk free-text notes into its sections, sentences, and tokens. The information extracted in this preprocessing step was used by the statistical and rule-based extractors as features. Findings: Performance results for 25 extractors (14 statistical, 11 rule based) are presented. The average f1-scores for 11 rule-based extractors and 14 statistical extractors are 0.785 (min=0.576,max=0.931,std-dev=0.113) and 0.812 (min=0.571,max=0.993,std-dev=0.135) respectively. Discussion: Our error analysis revealed that most extraction errors were due either to data imbalance in the data set or the way the gold standard had been created. Conclusion: As future work, more experiments will be conducted with a more comprehensive data set from multiple institutions contributing to the QI project. PMID:25848598

  4. Echocardiography to magnetic resonance image registration for use in image-guided cardiac catheterization procedures

    International Nuclear Information System (INIS)

    We present a robust method to register three-dimensional echocardiography (echo) images to magnetic resonance images (MRI) based on anatomical features, which is designed to be used in the registration pipeline for overlaying MRI-derived roadmaps onto two-dimensional live x-ray images during cardiac catheterization procedures. The features used in image registration are the endocardial surface of the left ventricle and the centre line of the descending aorta. The MR-derived left ventricle surface is generated using a fully automated algorithm, and the echo-derived left ventricle surface is produced using a semi-automatic segmentation method provided by the QLab software (Philips Healthcare) that it is routinely used in clinical practice. We test our method on data from six volunteers and four patients. We validated registration accuracy using two methods: the first calculated a root mean square distance error using expert identified anatomical landmarks, and the second method used catheters as landmarks in two clinical electrophysiology procedures. Results show a mean error of 4.1 mm, which is acceptable for our clinical application, and no failed registrations were observed. In addition, our algorithm works on clinical data, is fast and only requires a small amount of manual input, and so it is applicable for use during cardiac catheterization procedures.

    Introduction The association between both left and right ventricular free wall ruptures (FWR) and post-infarction anterior ventricular septal defect (VSD) is an exceptional situation. Case report We present the case of a patient who developed a VSD and two FWRs (of the left and right ventricle, respectively) shortly after the onset of an anterior AMI. We surgically closed this complex rupture using the cohesive double patch technique with two Teflon patches combined with an infarct exclusion technique. The left and right ventricular patches were attached cohesively to the septal wall and the infarcted area was excluded without reducing the left ventricular cavity. Conclusion Association between post-infarction ventricular septal rupture and both left and right free wall ruptures are a very rare and dangerous situation. The modified cohesive double patch technique associated the modified Cooley technique seems to be the correct surgical solution. PMID:27385145

    Full Text Available Abstract Inflammatory myofibroblastic tumor is currently considered to be a low-grade neoplasm, and it rarely involves the heart. We reported a rare case of a 59-year-old female who received cardiac surgery for complete resection of inflammatory myofibroblastic tumor in the left atrium. Five months after surgery, the patient presented with acute cardiogenic pulmonary edema and subsequent sudden death due to a left atrial tumor which protruded into the left ventricle through mitral annulus during diastole. The recurrence of inflammatory myofibroblastic tumor in the left atrium was strongly suggested clinically.

  10. Estimating effective dose for a cardiac catheterisation procedure with single or double personal dosemeters

    International Nuclear Information System (INIS)

    In most countries of the European Union legislation requires individual determination and registration of the dose to radiological workers exposed to ionising radiation to check whether dose limits are exceeded. To assess stochastic risk, ideally effective dose (E) should be known. In practice, personal dose equivalent [Hp(10)] is used as it can be measured with a personal dosemeter. The dosemeter reading may provide a reasonable assessment of Hp(10), but it may deviate strongly from E, in particular in radiology procedures for medical diagnosis or intervention when protective clothing like lead-equivalent apron and thyroid collar is worn. In the literature various correction factors and algorithms to convert readings of single or dual dosemeters to an estimate of E can be found. An illustrative example of a cardiac catheterisation procedure, in which dose calculations are made by Monte Carlo simulation of radiation transport, shows that such corrections may still yield considerable overestimation.

    International Nuclear Information System (INIS)

    Purpose: System-related complications in surgically implanted catheter-port systems (CPS) for intraarterial (i.a.) chemotherapy are well known. In most cases of complications, the treatment must be interrupted and the catheter-port system must be repaired surgically. We describe microinvasive interventional radiological procedures to correct some dysfunctions of CPS.Methods: Five patients with repetitive dysfunction of CPS were treated with interventional techniques. Two patients presented with perfusion impairment, one patient had a pseudoaneurysm of the hepatic artery, and two patients presented with catheter displacement. Radiological interventions included mechanical recanalization with a guidewire, vascular stenting, and correction of catheter dislocation with a gooseneck snare.Results: In all cases, correct function of the CPS was restored. No intervention-related complications occurred and surgery was avoided. Chemotherapy could be continued for a period of 4-10 months.Conclusion: For some system-related complications, minimally invasive radiological interventions can be used to restore the function of CPS for i.a. chemotherapy.

    Full Text Available Background. Hypothermia in the surgical patients can be the consequence of long duration of surgical intervention, general anesthesia and low temperature in operating room. Postoperative hypothermia contributes to a number of postoperative complications such as arrhythmia, myocardial ischemia, hypertension, bleeding, wound infection, coagulopathy, prolonged effect of muscle relaxants. External heating procedures are used to prevent this condition, but some investigations reported that infusion of aminoacids during surgery can induce thermogenesis and prevent postoperative hypothermia. Case report. We reported two males who underwent major colorectal surgery for rectal carcinoma. One patient received Aminosol 15% solution, 125 ml/h, while the other did not. The esophageal temperatures in both cases were measured every 30 minutes during the operation and 60 minutes after in Intensive Care Unit. We were monitoring blood pressure, heart rate, ECG, and shivering. Patient who received aminoacids showed ameliorated postoperative hypothermia without hypertension, arrhythmia, or shivering, while the other showed all symptoms mentioned above. Conclusion. According to literature data, as well as our findings, we can conclude that intraoperative intravenous treatment with amino acid solution ameliorates postoperative hypothermia along with its complications. .

    Biotelemetry is a useful tool to monitor the movements of animals and is widely applied in fisheries research. Radio or acoustic technology can be used, depending on the study design and the environmental conditions in the study area. A broad definition of telemetry also includes the use of Passive Integrated Transponder (PIT) tags, either separately or with a radio or acoustic transmitter. To use telemetry, fish must be equipped with a transmitter. Although there are several attachment procedures available, surgical implantation of transmitters in the abdominal cavity is recognized as the best technique for long-term telemetry studies in general (Stasko and Pincock, 1977; Winter, 1996; Jepsen, 2003), and specifically for juvenile salmonids, Oncorhynchus spp. (Adams and others, 1998a, 1998b; Martinelli and others, 1998; Hall and others, 2009). Studies that use telemetry assume that the processes by which the animals are captured, handled, and tagged, as well as the act of carrying the transmitter, will have minimal effect on their behavior and performance. This assumption, commonly stated as a lack of transmitter effects, must be valid if telemetry studies are to describe accurately the movements and behavior of an entire population of interest, rather than the subset of that population that carries transmitters. This document describes a standard operating procedure (SOP) for surgical implantation of radio or acoustic transmitters in juvenile salmonids. The procedures were developed from a broad base of published information, laboratory experiments, and practical experience in tagging thousands of fish for numerous studies of juvenile salmon movements near Columbia River and Snake River hydroelectric dams. Staff from the Western Fisheries Research Center's Columbia River Research Laboratory (CRRL) frequently have used telemetry studies to evaluate new structures or operations at hydroelectric dams in the Columbia River Basin, and these evaluations typically

    2005-11-01

    as an intermediate therapeutical option between conservative and operative management of small lumbar disc herniations or protrusions causing sciatica. Two RCT comparing transforaminal endoscopic procedures with microdiscectomy in patients with sciatica and small non-sequestered disc herniations show comparable short and medium term overall success rates. Concerning speed of recovery and return to work a trend towards more favourable results for the endoscopic procedures is noted. It is doubtful though, whether these results from the eleven and five years old studies are still valid for the more advanced procedures used today. The only RCT comparing the results of automated percutaneous lumbar discectomy to those of microdiscectomy showed clearly superior results of microdiscectomy. Furthermore, success rates of automated percutaneous lumbar discectomy reported in the RCT (29% differ extremely from success rates reported in case series (between 56% and 92%. The literature search retrieves no controlled trials to assess efficacy and/or effectiveness of laser-discectomy, percutaneous manual discectomy or endoscopic procedures using a posterior approach in comparison to the standard procedures. Results from recent case series permit no assessment of efficacy, especially not in comparison to standard procedures. Due to highly selected patients, modi-fications of operative procedures, highly specialised surgical units and poorly standardised outcome assessment results of case series are highly variable, their generalisability is low. The results of the five economical analyses are, due to conceptual and methodological problems, of no value for decision-making in the context of the German health care system. Discussion: Aside from low methodological study quality three conceptual problems complicate the interpretation of results. 1. Continuous further development of technologies leads to a diversity of procedures in use which prohibits generalisation of study results

  1. The changing distribution of a major surgical procedure across hospitals: were supply shifts and disequilibrium important?

    1995-01-01

    This paper describes and analyzes the changing distribution across hospitals in the U.S. of total hip replacement surgery (THR) for the period 1980-1987. THR is one of the most costly single procedures contributing to health care expenses. Also, the use of THR exhibits a particularly high degree of geographic variation. Recent research pointed to shifts in demand as one plausible economic explanation for increasing use of THR. This paper questions whether shifts in supply may have been large enough to explain changes in patient mix and the relationship of patient mix to the number of procedures performed at a particular hospital. In addition, the relationship between total use of THR and the local availability of orthopaedic surgeons as well as the average allowable Medicare fee for standardized physician services is analyzed. These relationships might yield evidence to support a scenario of induced demand beyond the optimum for patients' welfare, or evidence of supply increase within a disequilibrium scenario. This study, using data for all THR patients in a large sample of hospitals, tends to reject the formulation of a market with independent supply and demand shifts where the supply shifts were the dominant forces. Hospitals with a larger number of THRs performed did not see a higher percentage of older, sicker, and lower income patients. It was more likely that demand shifts generated increases in capacity for surgical services. Moreover, there was little evidence for a persistent disequilibrium and only weak evidence for inducement. Also, we found little evidence that hospitals responded to financial incentives inherent in the Medicare payment system after 1983 to select among THR candidates in favour of those with below average expected cost. We did observe increased concentration over time of THR procedures in facilities with high volume--suggesting plausible demand shifts towards hospitals with a priori quality and cost advantages or who obtained those

  2. Minimising radiation exposure to physicians performing fluoroscopically guided cardiac catheterisation procedures: A review

    International Nuclear Information System (INIS)

    What is known about radiation exposure to physicians who perform cardiac interventions is reviewed and various factors that affect their exposure are discussed. There are wide variations in the radiation dose (up to 1000-fold) per procedure. Despite extensive improvements in equipment and technology, there has been little or no reduction in dose over time. The wide variation and lack of reduction in operator doses strongly suggests that more attention must be paid to factors influencing the operator dose. Numerous patient, physician and shielding factors influence the operator dose to different degrees. Operators can change some of these factors immediately, at minimal or no cost, with a substantial reduction in dose and potential cancer risk. (authors)

    Full Text Available Aims and Objectives: To compare the efficacy of sedation and time taken for extubation using dexmedetomidine and fentanyl sedation in post-operative paediatric cardiac surgical patients. Methods: A prospective randomized double-blind study involving 60 children undergoing open heart surgery was conducted. The patients were divided into two groups, each involving 30 patients. One group received fentanyl at 1 μg/kg/h (Group A and the other received dexmedetomidine at 0.5 μg/kg/h (Group B for post-operative sedation with intermittent rescue fentanyl 0.5 μg/kg bolus in either group as per requirement during suctioning. The efficacy of sedation was assessed using the Ramsay sedation score, paediatric intensive care unit sedation score and the tracheal suction score. The time taken for extubation from the stoppage of infusion was noted. Results: Haemodynamic parameters between the two groups were comparable. All sedation scores were comparable in the fentanyl and dexmedetomidine groups. Average time (in minutes required for extubation was 131.0 (±51.06 SD in the dexmedetomidine group compared with 373.0 (±121.4 SD in the fentanyl group. The difference in mean time for extubation was statistically significant. Conclusions: Dexmedetomidine facilitates adequate sedation for mechanical ventilation and also early extubation as compared with fentanyl.

    Full Text Available Atrial fibrillation is one of the most common types of heart rhythm disturbances in humans. «Maze III» procedure is considered to be the most radical methods of surgical treatment for atrial fibrillation. It is performed according to the «incision-suture» technique using median sternotomy and cardiopulmonary bypass. This procedure is less frequently used in clinical practice because of its technical complexity, but the evaluation of longterm results is necessary to answer the question of expediency for using the new methods of surgical treatment for atrial fibrillation which were developed in view of essential principles of classical surgery. The clinical case of successful surgical treatment for atrial fibrillation with 18-years of follow-up is presented in the article.

    Abstract The aim of the study is to evaluate the therapeutic effect of a new surgical procedure, dumbbell-form resection (DFR), for hilar cholangiocarcinoma (HCCA) with severe jaundice. In DFR, liver segments I, IVb, and partial V above the right hepatic pedicle are resected. Hemihepatectomy is recognized as the preferred procedure; however, its application is limited in HCCAs with severe jaundice. Thirty-eight HCCA patients with severe jaundice receiving DFR and 70 receiving hemihepatectomy from January 2008 to January 2013 were included. Perioperative parameters, operation-related morbidity and mortality, and post-operative survival were analyzed. A total of 21.1% patients (8/38) in the DFR group received percutaneous transhepatic biliary drainage (PTBD), which was significantly <81.4% (57/70) in the hemihepatectomy group. The TBIL was higher in the DFR group at operation (243.7 vs 125.6 μmol/L, respectively). The remnant liver volume was significantly higher after DFR. The operation-related morbidity was significantly lower after DFR than after hemihepatectomy (26.3% vs 48.6%, respectively). None of the patients died during the perioperative period after DFR, whereas 3 died after hemihepatectomy. There was no difference in margin status, histological grade, lymph-node involvement, and distant metastasis between the 2 groups. The 1-, 3-, and 5-year survival rates after DFR (68.4%, 32.1%, and 21.4%, respectively) showed no significant difference with those after hemihepatectomy (62.7%, 34.6%, and 23.3%, respectively). Kaplan–Meier analysis indicated that overall survival and recurrence after DFR demonstrated no significant difference compared with hemihepatectomy. DFR appears to be feasible for selected HCCA patients with severe jaundice. However, its indications should be restricted. PMID:26765439

  9. Does grid-controlled fluoroscopy lower patient doses during adult cardiac procedures ?

    International Nuclear Information System (INIS)

    Purpose: Commercial companies advertise grid-controlled fluoroscopy as a tool that significantly lowers patient and consequently staff doses. In the haemodynamic unit of Athens General Hospital, a Philips Allura FP10 digital flat panel system equipped with a grid-controlled X-ray tube has been installed in 2004. Twenty months later, the grid ceased to function and the question arose whether the X-ray tube should be replaced. Since the cost of grid-controlled X-ray tube is very high, it was decided that the laboratory should continue working as long as the X-ray tube would function. Material and Method: Since interventional procedures are known to be associated with high radiation doses, patient doses are routinely recorded. The data include fluoroscopy time, number of images acquired, as well as the total and fluoroscopic Dose-Area-Product (DAP) dose delivered to patient. From our dose records patient doses collected during Coronary Angiography (CA) and Percutaneous Transluminal Coronary Angioplasty (PTCA) with and without the grid-controlled fluoroscopy present were compared on a total sample of 998 patients. Results: The analysis of the results showed that (a) no statistically significant patient dose increase was noticed with grid not in use, (b) the difference in fluoroscopy time was not statistically significant for CA procedures, while it was statistically significant for PTCA procedures and (c) for both kinds of procedures the difference in number of frames, with and without the grid in use, was statistically significant (more frames when grid not in use). Conclusion: The results of this study suggest that hospital administrators may question the costly investment on grid-controlled X-ray tubes, with the deficient function of which -during adult cardiac diagnostic and therapeutic interventions-, patient dose does not increase, even when more frames are recorded.

    A sampling probe based on ambient desorption ionization was designed for in vivo chemical analysis by mass spectrometry in surgical and endoscopic procedures. Sampling ionization of analytes directly from tissue was achieved by sealing the sampling tip against the tissue surface without allowing leakage of the auxiliary gas used for desorption ionization. The desorbed charged species were transferred over a long distance (up to 4 m) through a flexible tube of internal diameter as small as 1/16 in. to the inlet of the mass spectrometer used for analysis. The conditions used for desorption electrospray ionization (DESI) were optimized to achieve biocompatibility for clinical applications while obtaining adequate efficiency for the analysis. This optimization involved the removal of high voltage and use of pure water as a spray solvent instead of the organic solvents or aqueous mixtures normally used. Improved sensitivity was achieved under these conditions by increasing the gas flow rate in the transfer tube. The destructive effect on tissue surfaces associated with typical desorption ionization was avoided by altering the local gas dynamics in the sample area without compromising the overall analysis efficiency.

    Otologic procedures require a still surgical field and are associated with a 50% incidence of emetic symptoms. Propofol reduces nausea and vomiting but not intraoperative movement. This study compares a remifentanil/propofol anesthetic to a propofol/fentanyl combination to determine which provides the best perioperative conditions for otologic microsurgery. Eighty healthy patients were randomly assigned to receive one of the anesthetic combinations. Demographic data, hemodynamic variables, movement, and bispectral index monitoring values in addition to anesthetic emergence, nausea, vomiting, pain, and other recovery variables were compared between groups with appropriate statistical methods. Both groups were similar. Times to eye opening (7.7 +/- 0.7 vs 12.4 +/- 1.2 minutes) and extubation (9.8 +/- 0.9 vs 12.4 +/- 1.0 minutes) were shorter with remifentanil. This group also had lower hemodynamic variables and movement (23% vs 65%) under anesthesia. Postoperative pain was mild in both groups, but remifentanil patients had more than the propofol group. All other postoperative parameters were similar. Remifentanil-based anesthesia produces better hemodynamic stability, less movement, and faster emergence after otologic surgery, with propofol's antiemetic effect, for the same cost. PMID:10652394

    Full Text Available Background:  Elbow surgery is shared by several subspecialties. We were curious about the most common elbow surgeries and their corresponding diagnoses in the United States.   Methods:  We used the National Hospital Discharge Survey (NHDS and the National Survey of Ambulatory Surgery (NSAS data gathered in 2006-databases that together provide an estimate of all inpatient and ambulatory surgical care in the US.  Results:  An estimated 150,000 elbow surgeries were performed in the US in 2006, 75% in an outpatient setting. The most frequent diagnosis treated operative was enthesopathy (e.g. lateral epicondylitis and it was treated with several different procedures. More than three quarters of all elbow surgeries treated enthesopathy, cubital tunnel syndrome, or fracture (radial head in particular. Arthroscopy and arthroplasty accounted for less than 10% of all elbow surgeries.  Conclusions:  Elbow surgery in the United States primarily addresses enthesopathies such as tennis elbow, cubital tunnel syndrome, and trauma. It is notable that some of the most common elbow surgeries (those that address enthesopathy and radial head fracture are some of the most variably utilized and debated.

    Full Text Available CARTO XP is an electroanatomical cardiac mapping system that provides 3D color-coded maps of the electrical activity of the heart; however it is expensive and it can only use a single costly magnetic catheter for each patient intervention. Our approach consists of integrating fluoroscopic and electrical data from the RF catheters into the same image so as to better guide RF ablation, shorten the duration of this procedure, increase its efficacy, and decrease hospital cost when compared to CARTO XP. We propose a method that relies on multi-view C-arm fluoroscopy image acquisition for (1 the 3D reconstruction of the anatomical structure of interest, (2 the robust temporal tracking of the tip-electrode of a mapping catheter between the diastolic and systolic phases and (3 the 2D/3D registration of color coded isochronal maps directly on the 2D fluoroscopy image that would help the clinician guide the ablation procedure much more effectively. The method has been tested on canine experimental data.

    Full Text Available The CARTO XP ablation system provides real-time data on 3D, color-coded maps of the electrical activity of the heart; however, it is expensive and can only use a dedicated costly magnetic catheter per patient intervention. The purpose of our study is to shorten the duration of the radiofrequency ablation procedure and increase its efficacy by developing an affordable prototype catheter navigation system that simulates the CARTO system. To obtain 3D geometrical data from catheter locations inside the heart chamber, we acquired only single-view images using an Integris Allura fluoroscope and estimated the depth of the mapping electrode using pattern recognition techniques. Validation was performed in ideal and clinical conditions. For phantom experiment, when using a 7-French catheter, the average recovered depth error was 2.05±1.46 mm using a single image. However, when using the 8-French catheter, the average recovered depth error was 1.54±1.29 mm. In clinical experimentation, the standard error of estimate for the estimated depth was about 13.1 mm and 10.1 mm, respectively, for the posterior and lateral views. In conclusion, this paper describes our achievements and shortfalls in developing an affordable fluoroscopic navigation system to guide RF catheter ablation of cardiac arrhythmias.

    Full Text Available OBJECTIVE Anesthetic management for interventional cardiac procedures/cardiac catheterization in pediatric patients is challenging. Cardiac anomalies vary from simple to complex congenital cardiac anomalies, shunts may be present at multiple levels and patients may be profoundly cyanotic, may be with ventricular dysfunction. They usually require sedation and analgesia to maintain steady stable state. In adults, such type of procedures can be well managed with local anesthesia. METHODS Fifty patients were included in the study. They were randomly divided into two groups- Group A (n=25 patients received femoral N. block along with IV sedation and analgesia while group B (n=25 patients received only IV sedation and analgesia. Both groups were compared for hemodynamics, pain score and requirement of IV anesthetic agents and any complications if come up. RESULTS Group A patients required IV ketamine 3.24mg/kg (±0.31SD as compared to 5.58mg/kg (±1.6SD in group B, which suggests significantly reduced requirement of IV anesthetic agents in group where femoral nerve block has been given. Hemodynamic parameters remained stable and comparable (no statistically significant variation Pain score was less in group A patients than group B. CONCLUSION It has been observed that Group A patients required less dosages of IV anesthetic agents, with stable hemodynamics and less pain score and sedation score as compared to group B patients.

    The European Snapshot Survey on Procedural Routines for Electronic Device Implantation (ESS-PREDI) was a prospective European survey of consecutive adults who had undergone implantation/surgical revision of a cardiac implantable electronic device (CIED) on chronic antithrombotic therapy (enrolment March-June 2015). The aim of the survey was to investigate perioperative treatment with oral anticoagulants and antiplatelets in CIED implantation or surgical revision and to determine the incidence of complications, including clinically significant pocket haematomas. Information on antithrombotic therapy before and after surgery and bleeding and thromboembolic complications occurring after the intervention was collected at first follow-up. The study population comprised 723 patients (66.7% men, 76.9% aged ≥66 years). Antithrombotic treatment was continued during surgery in 489 (67.6%) patients; 6 (0.8%) had their treatment definitively stopped; 46 (6.4%) were switched to another antithrombotic therapy. Heparin bridging was used in 55 out of 154 (35.8%) patients when interrupting vitamin K antagonist (VKA) treatment. Non-vitamin K oral anticoagulant (NOAC) treatment was interrupted in 88.7% of patients, with heparin bridging in 25.6%, but accounted for only 25.3% of the oral anticoagulants used. A total of 108 complications were observed in 98 patients. No intracranial haemorrhage or embolic events were observed. Chronic NOAC treatment before surgery was associated with lower rates of minor pocket haematoma (1.4%; P= 0.042) vs. dual antiplatelet therapy (13.0%), VKA (11.4%), VKA + antiplatelet (9.2%), or NOAC + antiplatelet (7.7%). Similar results were observed for bleeding complications (P= 0.028). Perioperative management of patients undergoing CIED implantation/surgical revision while on chronic antithrombotic therapy varies, with evidence of a disparity between guideline recommendations and practice patterns in Europe. Haemorrhagic complications were significantly

  20. Calculation of entrance exposed area from recorded images in cardiac diagnostic and interventional procedures

    International Nuclear Information System (INIS)

    With increasing number of interventional radiological procedures performed on patients of all ages, it is important to determine the skin entrance dose of patients to limit the side effects of radiation. In most cases the skin dose is measured using thermoluminescent detectors (TLD). However, these detectors need to be placed in the radiation field on the skin of the patient, which may interfere with the procedure. Also, not all radiological practices are equipped with TLD readers which are expensive or have staff with the appropriate knowledge and expertise to be able to make use of TLD. The alternative to TLD is to use the dose area product (DAP) measured with a diamentor fitted to the angiography x-ray equipment. The difficulties in using DAP to calculate skin dose is that the irradiated area of the skin is not known. The area could change in size and location during the procedure as the radiologist/medical specialist varies the collimation and region of interest. For angiography equipment the distance between the anode and image intensifier is variable, as is the height of the examination table. The only point of reference is the isocentre. With recorded images it is possible to determine the irradiated area of the patient at the isocentre plane using the stenosis algorithm. The recorded image is calibrated such that it corresponds to the physical size in the plane of the isocentre. For non-recorded images, it may be necessary to assume that collimation has not changed and that the irradiated area is the same as that shown on the recorded images. The Women's and Children's Hospital has a Toshiba DFP2000 Biplane Digital Imaging system used for all cardiac and general angiography and interventional procedures. With this system the exposure factors (kVp, mA, field sizes) are recorded with the images. The source to image distance (SID), magnification factor (calibration factor of the recorded images) and angle of rotation are displayed on the Display Panel of the

    Debate over the role of Becker expander implants (BEIs) in breast reconstruction is still ongoing. There are no clear indications for BEI use. The main indications for BEI use are one-stage breast reconstruction procedure and congenital breast deformities correction, due to the postoperative ability to vary BEI volume. Recent studies showed that BEIs were removed 5 years after mammary reconstruction in 68% of operated patients. This entails a further surgical procedure. BEIs should not, therefore, be regarded as one-stage prostheses. We performed a case-series study of breast reconstructions with anatomically shaped Becker-35™ implants, in order to highlight complications and to flag unseen problems, which might entail a second surgical procedure. A total of 229 patients, reconstructed from 2005 to 2010, were enrolled in this study. Data relating to implant type, volume, mean operative time and complications were recorded. All the patients underwent the same surgical procedure. The minimum follow-up period was 18 months. During a 5-year follow-up, 99 patients required secondary surgery to correct their complications or sequelae; 46 of them underwent BEI removal within 2 years of implantation, 56 within 3 years, 65 within 4 years and 74 within 5 years. Our findings show that two different sorts of complications can arise with these devices, leading to premature implant removal, one common to any breast implant and one peculiar to BEIs. The Becker implant is a permanent expander. Surgeons must, therefore, be aware that, once positioned, the Becker expander cannot be adjusted at a later date, as in two-stage expander/prosthesis reconstructions for instance. Surgeons must have a clear understanding of possible BEI complications in order to be able to discuss these with their patients. Therefore, only surgeons experienced in breast reconstruction should use BEIs. PMID:23478009

  2. The usefulness of myocardial SPECT for the preoperative cardiac risk evaluation in noncardiac surgery

    International Nuclear Information System (INIS)

    We investigated whether myocardial SPECT had additional usefulness to clinical, functional or surgical indices for the preoperative evaluation of cardiac risks in noncardiac surgery. 118 patients ( M: F=66: 52, 62.7±10.5 years) were studied retrospectively. Eighteen underwent vascular surgeries and 100 nonvascular surgeries. Rest Tl-201/ stress Tc-99m-MIBI SPECT was performed before operation and cardiac events (hard event: cardiac death and myocardial infarction; soft event: ischemic ECG change, congestive heat failure and unstable angina) were surveyed through perioperative periods (14.6±5.6 days). Clinical risk indices, functional capacity, surgery procedures and SPECT findings were tested for their predictive values of perioperative cardiac events. Peri-operative cardiac events occurred in 25 patients (3 hard events and 22 soft events). Clinical risk indices, surgical procedure risks and SPECT findings but functional capacity were predictive of cardiac events. Reversible perfusion decrease was a better predictor than persistent decrease. Multivariate analysis sorted out surgical procedure risk (p=0.0018) and SPECT findings (p=0.0001) as significant risk factors. SPECT could re-stratify perioperative cardiac risks in patients ranked with surgical procedures. We conclude that myocardial SPECT provides additional predictive value to surgical type risks as well as clinical indexes or functional capacity for the prediction of preoperative cardiac events in noncardiac surgery

    Surgical simulation increasingly appears to be an essential aspect of tomorrow's surgery. The development of a hepatic surgery simulator is an advanced concept calling for a new writing system which will transform the medical world: virtual reality. Virtual reality extends the perception of our five senses by representing more than the real state of things by the means of computer sciences and robotics. It consists of three concepts: immersion, navigation and interaction. Three reasons have led us to develop this simulator: the first is to provide the surgeon with a comprehensive visualisation of the organ. The second reasons is to allow for planning and surgical simulation that could be compared with the detailed flight-plan for a commercial jet pilot. The third lies in the fact that virtual reality is an integrated part of the concept of computer assisted surgical procedure. The project consists of a sophisticated simulator which must include five requirements: a) visual fidelity, b) interactivity, c) physical properties, d) physiological properties, e) sensory input and output. In this report we describe how to obtain a realistic 3D model of the liver from bi-dimensional 2D medical images for anatomical and surgical training. The introduction of a tumor and the consequent planning and virtual resection is also described, as are force feedback and real-time interaction. PMID:9752550

    Surgical exposure is a surgical method to expose mucous or bone which prevent delayed or unerupted permanent crown teeth, in order to provide normal eruption and to prevent malocclusion. Surgical exposure is usually carried out on maxillary caninces as they have higher incidence of delayed eruption. Nevertheless, this procedure can also be performed on other teeth. For patient management, this procedure need cooperation betweent oral surgeon and orthodontist.

  9. Comprehensive evaluation of occupational radiation exposure to intraoperative and perioperative personnel from 18F-FDG radioguided surgical procedures

    International Nuclear Information System (INIS)

    The purpose of the current study was to comprehensively evaluate occupational radiation exposure to all intraoperative and perioperative personnel involved in radioguided surgical procedures utilizing 18F-fluorodeoxyglucose (18F-FDG). Radiation exposure to surgeon, anesthetist, scrub technologist, circulating nurse, preoperative nurse, and postoperative nurse, using aluminum oxide dosimeters read by optically stimulated luminescence technology, was evaluated during ten actual radioguided surgical procedures involving administration of 18F-FDG. Mean patient dosage of 18F-FDG was 699 ± 181 MBq (range 451-984). Mean time from 18F-FDG injection to initial exposure of personnel to the patient was shortest for the preoperative nurse (75 ± 63 min, range 0-182) followed by the circulating nurse, anesthetist, scrub technologist, surgeon, and postoperative nurse. Mean total time of exposure of the personnel to the patient was longest for the anesthetist (250 ± 128 min, range 69-492) followed by the circulating nurse, scrub technologist, surgeon, postoperative nurse, and preoperative nurse. Largest deep dose equivalent per case was received by the surgeon (164 ± 135 μSv, range 10-580) followed by the anesthetist, scrub technologist, postoperative nurse, circulating nurse, and preoperative nurse. Largest deep dose equivalent per hour of exposure was received by the preoperative nurse (83 ± 134 μSv/h, range 0-400) followed by the surgeon, anesthetist, postoperative nurse, scrub technologist, and circulating nurse. On a per case basis, occupational radiation exposure to intraoperative and perioperative personnel involved in 18F-FDG radioguided surgical procedures is relatively small. Development of guidelines for monitoring occupational radiation exposure in 18F-FDG cases will provide reassurance and afford a safe work environment for such personnel. (orig.)

    Full Text Available Introducation: The long-term outcome and clinical results of gaparthroplasty used for the treatment of condylar ankylosis of the mandible in children with application of postoperative activator appliances and costochondral rib graft are evaluated and compared. The purpose of this study was to compare the effect of gap arthroplasty and costochondral graft methods on reankylosis, a mount of mouth opening and growth. Materials and Methods: A non-randomized, retrospective clinical study of l0 cases (5-12 years old of condylar ankylosis of the mandible, surgically treated during a 10 year period from 2002 to 2012 was performed. Four patients were treated by condylectomy and interpositional flap, whereas six were treated by condylectomy and immediate costachondral rib grafts. The first group underwent long-term postoperative therapy using removable activator appliances. Casts, radiographs, photographs, and computed tomography (CT were used post surgically to evaluate rib graft, condylar growth and function, occlusion, facial, and condylar symmetry. Data were analyzed by SPSS 16 statistical software using Mann-Whitney, Paired T-test and Chi-square tests. Results: Children with long-standing condylar ankylosis of the mandible treated by condylectomy and interpositional flap showed more favorably when activators were used post-surgically. Conclusions: Gaparthroplasty with functional activator post-operatively can be considering for TMJ ankylosis.

    Full Text Available Abstract Background Left ventricle (LV 3D structural data can be easily obtained using standard transesophageal echocardiography (TEE devices but quantitative pre- and intraoperative volumetry and geometry analysis of the LV is presently not feasible in the cardiac operation room (OR. Finite element method (FEM modelling is necessary to carry out precise and individual volume analysis and in the future will form the basis for simulation of cardiac interventions. Method A Philips/HP Sonos 5500 ultrasound device stores volume data as time-resolved 4D volume data sets. In this prospective study TomTec LV Analysis TEE© Software was used for semi-automatic endocardial border detection, reconstruction, and volume-rendering of the clinical 3D echocardiographic data. With the software FemCoGen© a quantification of partial volumes and surface directions of the LV was carried out for two patients data sets. One patient underwent surgical ventricular repair therapy (SVR and the other a cardiac resynchronisation therapy (CRT. Results For both patients a detailed volume and surface direction analysis is provided. Partial volumes as well as normal directions to the LV surface are pre- and post-interventionally compared. Conclusion The operation results for both patients are quantified. The quantification shows treatment details for both interventions (e.g. the elimination of the discontinuities for CRT intervention and the segments treated for SVR intervention. The LV quantification is feasible in the cardiac OR and it gives a detailed and immediate quantitative feedback of the quality of the intervention to the medical.

    Numerous methods of surgical repair for scaphocephaly (sagittal synostosis) have been reported in the literature, from strip craniectomies to more complex methods of calvarial vault remodeling. While good cosmesis and restoration of a normal anteroposterior diameter may be obtained with these methods, a more rounded contour of the biparietal areas is often more difficult to achieve. We describe a modification of the Pi technique, described by Jane in 1976, that results in a more rounded contour of the biparietal areas. We report our experience on cranial vault remodeling for the correction of scaphocephaly in 51 patients from 1998 to 2011. PMID:23154346

    In this Statistical Grand Rounds, we review methods for the analysis of the diversity of procedures among hospitals, the activities among anesthesia providers, etc. We apply multiple methods and consider their relative reliability and usefulness for perioperative applications, including calculations of SEs. We also review methods for comparing the similarity of procedures among hospitals, activities among anesthesia providers, etc. We again apply multiple methods and consider their relative reliability and usefulness for perioperative applications. The applications include strategic analyses (e.g., hospital marketing) and human resource analytics (e.g., comparisons among providers). Measures of diversity of procedures and activities (e.g., Herfindahl and Gini-Simpson index) are used for quantification of each facility (hospital) or anesthesia provider, one at a time. Diversity can be thought of as a summary measure. Thus, if the diversity of procedures for 48 hospitals is studied, the diversity (and its SE) is being calculated for each hospital. Likewise, the effective numbers of common procedures at each hospital can be calculated (e.g., by using the exponential of the Shannon index). Measures of similarity are pairwise assessments. Thus, if quantifying the similarity of procedures among cases with a break or handoff versus cases without a break or handoff, a similarity index represents a correlation coefficient. There are several different measures of similarity, and we compare their features and applicability for perioperative data. We rely extensively on sensitivity analyses to interpret observed values of the similarity index. PMID:26678472

    Prosthetic rehabilitation of patients with oral submucous fibrosis (OSMF) offers a formidable challenge due to restricted mouth opening. Physiotherapy via interocclusal force application is the mainstay for surgical treatment. Herein, we report a case of a man with OSMF requiring construction of dentures. The main objective was to deliver intra-operative and post operative inter occlusal forces without fracturing the mandible and thus providing rehabilitation to the patient prosthetically. An edentulous male patient reported with grade IVA OSMF to our department to improve his mouth opening for denture construction. The patient was managed successfully using surgical sectioning of the fibrous bands. Inter occlusal force application for mouth opening during the operation and post operative physiotherapy were facilitated using custom-made occlusal splints. Satisfactory mouth opening was achieved, with good healing and no event of infection or fracture. Here, we propose an easy method to achieve adequate mouth opening in an edentulous patient of OSMF, with atrophic ridges; without the chances of fracture of either jaw. PMID:22442590

    Nausea and vomiting following anesthesia is a distressing problem for the patient as it increases the recovery time, intensity of nursing care and delays discharge. The aim of randomized controlled single blind study is to evaluate the efficacy and safety of subhypnotic doses of propofol for the prevention of postoperative nausea and vomiting (PONV) in day care management of cases in oral and maxillofacial surgeries. Twenty-five patient of ASA-1 with age ranging from 12 to 40 years were scheduled for various maxillofacial surgical cases like fracture, cyst enucleation, surgical removal of 3rd molar, etc. were given propofol at the dose of 2 to 2.5 mg/kg as induction dose and sedation was maintained with the dose 5 to 10 mg/min. There was no significant effect on heart rate, systolic and diastolic blood pressure, respiratory rate and oxygen saturation intraoperatively. In conclusion, a subhypnotic dose of propofol is fast acting, safe and easily controllable, short acting general anesthetic agent with rapid recovery. The study found that the PONV was significantly reduced in the patient with propofol, no hemodynamic derangements were noted in the postoperative period. PMID:24309336

    Full Text Available Anaplastic carcinoma (AC or undifferentiated carcinoma of the pancreas is a rare variant among the malignant pancreatic neoplasms. These tumors have a poor prognosis with survival measured in months. The role of surgical palliation to improve the quality of life is not well defined in these patients. We report a case of AC of pancreas in a 65-year-old male patient. Patient had upper abdominal pain with frequent bilious vomiting. Computed tomography scan of the abdomen showed a mass in the body of pancreas with possible infiltration of duodenojejunal flexure (DJF. Laparotomy revealed an inoperable mass with posterior fixity and involvement of the DJF. Patient underwent a palliative duodenojejunostomy. Tissue biopsy from the tumor showed pleomorphic type AC with giant cells. Patient had good symptomatic relief from profuse vomiting and progressed well at follow up. AC of pancreas is a rare and aggressive malignancy with dismal outlook. If obstructive symptoms are present due to duodenal involvement, a palliative bypass may be a worthwhile surgical option in selected cases.

    Full Text Available Carcinoma of the external auditory canal (EAC is an unusual head and neck malignancy. The pathophysiology of these tumors is different from other skin lesions because of their anatomical and functional characteristics. Early-stage carcinoma of the EAC can be generally cured by surgical treatment, and reconstruction of the EAC with a tympanoplasty can help to retain hearing, thus improving the patients’ quality of life. In this study, we present two cases of early-stage carcinoma of the EAC treated by canal reconstruction using skin grafts after lateral temporal bone resection. A rolled-up skin graft with a temporal muscle flap was useful for keeping the form and maintaining the postoperative hearing. An adequate size of the skin graft and blood supply to the graft bed are important for achieving a successful operation.

    We present a feasibility study on hybrid echocardiography (echo) and x-ray image guidance for cardiac catheterization procedures. A self-tracked, remotely operated robotic arm with haptic feedback was developed that attached to a standard x-ray table. This was used to safely manipulate a three-dimensional (3D) trans-thoracic echo probe during simultaneous x-ray fluoroscopy and echo acquisitions. By a combination of calibration and tracking of the echo and x-ray systems, it was possible to register the 3D echo images with the 2D x-ray images. Visualization of the combined data was achieved by either overlaying triangulated surfaces extracted from segmented echo data onto the x-ray images or by overlaying volume rendered 3D echo data. Furthermore, in order to overcome the limited field of view of the echo probe, it was possible to create extended field of view (EFOV) 3D echo images by co-registering multiple tracked echo data to generate larger roadmaps for procedure guidance. The registration method was validated using a cross-wire phantom and showed a 2D target registration error of 3.5 mm. The clinical feasibility of the method was demonstrated during two clinical cases for patients undergoing cardiac pacing studies. The EFOV technique was demonstrated using two healthy volunteers.

  5. Coefficients calculations of conversion of cancer risk for occupational exposure using Monte Carlo simulations in cardiac procedures of interventionist radiology

    International Nuclear Information System (INIS)

    Cardiac procedures are among the most common procedures in interventional radiology (IR), and can lead to high medical and occupational exposures, as in most cases are procedures complex and long lasting. In this work, conversion coefficients (CC) for the risk of cancer, normalized by kerma area product (KAP) to the patient, cardiologist and nurse were calculated using Monte Carlo simulation. The patient and the cardiologist were represented by anthropomorphic simulators MESH, and the nurse by anthropomorphic phantom FASH. Simulators were incorporated into the code of Monte Carlo MCNPX. Two scenarios were created: in the first (1), lead curtain and protective equipment suspended were not included, and in the second (2) these devices were inserted. The radiographic parameters employed in Monte Carlo simulations were: tube voltage of 60 kVp and 120 kVp; filtration of the beam and 3,5 mmAl beam area of 10 x 10 cm2. The average values of CCs to eight projections (in 10-4 / Gy.cm2 were 1,2 for the patient, 2,6E-03 (scenario 1) and 4,9E-04 (scenario 2) for cardiologist and 5,2E-04 (scenario 1) and 4,0E-04 (Scenario 2) to the nurse. The results show a significant reduction in CCs for professionals, when the lead curtain and protective equipment suspended are employed. The evaluation method used in this work can provide important information on the risk of cancer patient and professional, and thus improve the protection of workers in cardiac procedures of RI

    Introduction We hypothesize that respiratory variation in the pulmonary artery tracing predicts fluid responsiveness (primary hypothesis) and that inclusion of multiple physiologic waveforms as well as ventilator settings in a predictive model of fluid responsiveness would lead to improvements in the clinical utility of this class of metrics (secondary hypothesis). Methods Blood pressure tracings were prospectively recorded in 35 patients immediately following cardiac surgery. Fluid bolus administration data, ventilator settings, and cardiac output were recorded prospectively before and after fluid boluses given at the discretion of the treating physician. Results We observed statistically significant but limited relationships between pulmonic (r(2) = .26, P = .0052) and systemic (r(2) = .13, P = .011) pulse pressure variation and changes in cardiac index. A multiparameter estimate of fluid responsiveness, which included respiratory variation in central venous pressure and pulmonary artery pressure, indexed tidal volumes, positive end-expiratory pressure, and mean airway pressure, was also correlated with change in cardiac index (r(2) = .42, P = .0056). Using the area under the curve (AUC) technique to compare specificity and sensitivity, dynamic indicators (AUC = 0.74, 0.67, and 0.81 for systemic arterial respiratory [pulse pressure] variation, pulmonic arterial respiratory [pulse pressure] variation, and the multiparameter estimate, respectively) outperformed static estimates (0.49 and 0.48 for central venous pressure and pulmonary artery diastolic pressure, respectively). Conclusion While integration of multiple physiologic waveforms as well as ventilator parameters improves the predictability of fluid responsive metrics in the setting of lung-protective ventilation, the composite index may still be of limited predictive value.

    Two pilot trials and one study in a closely related grebe species suggest that Western grebes (Aechmophorus occidentalis) will not tolerate intracoelomic transmitter implantation with percutaneous antennae and often die within days of surgery. Wild Western grebes (n = 21) were captured to evaluate a modified surgical technique. Seven birds were surgically implanted with intracoelomic transmitters with percutaneous antennae by using the modified technique (transmitter group), 7 received the same surgery without transmitter implantation (celiotomy group), and 7 served as controls (only undergoing anesthesia). Modifications included laterally offsetting the body wall incision from the skin incision, application of absorbable cyanoacrylate tissue glue to the subcutaneous space between the body wall and skin incisions, application of a waterproof sealant to the skin incision after suture closure, and application of a piece of porcine small intestine submucosa to the antenna egress. Survival did not differ among the 3 groups with 7 of 7 control, 6 of 7 celiotomy, and 6 of 7 transmitter birds surviving the 9-day study. Experimental birds were euthanized at the end of the study, and postmortem findings indicated normal healing. Significant differences in plasma chemistry or immune function were not detected among the 3 groups, and only minor differences were detected in red blood cell indices and plasma proteins. After surgery, the birds in the transmitter group spent more time preening tail feathers than those in the control and celiotomy groups. These results demonstrate that, in a captive situation, celiotomy and intracoelomic transmitter implantation caused minimal detectable homeostatic disturbance in this species and that Western grebes can survive implantation of intracoelomic transmitters with percutaneous antennae. It remains to be determined what potential this modified surgical procedure has to improve postoperative survival of Western grebes that are

    Full Text Available Background and Objectives: The purpose of this study was to evaluate the positional changes of the periodontal tissues, particularly the biological width, following surgical crown-lengthening in human subjects. Materials and Methods: A clinical trial study involving 15 patients was carried out for a period of 6 months. Sites were divided into 3 groups: treated (TT sites, adjacent (AD sites and nonadjacent (NAD sites. Free gingival margin [FGM], attachment level, pocket depth, bone level, biological width [BW] were recorded at baseline, 1, 3 and 6 months. Direct bone level after flap reflection was recorded before and after osseous resection at baseline only. Level of osseous crest was lowered based on BW, and supracrestal tooth structure needed using a combination of rotary and hand instruments. Statistical Analysis: Student t test and ANOVA were used. Results: Overall, apical displacement of FGM at TT, AD and NAD sites was statistically significant compared to baseline. The apical displacement of FGM at TT site was more when compared to that at AD and NAD sites at 3 and 6 months. The BW at the TT site was smaller at 1, 3 and 6 months compared to that at baseline. However, at all sites, BW was reestablished to the baseline value at the end of 6 months. Interpretation and Conclusion: The BW at TT sites was reestablished to its original vertical dimension by 6 months. In addition, a consistent 2-mm gain of coronal tooth structure was observed at the 1, 3 and 6-month examinations.

    Fifty five children with 57 cholesteatomas (2 bilateral cholesteatomas) were operated on by the same surgeon. The median period of follow-up was 87 months. Fifteen cases were lost to follow-up (26%). An ossicular erosion was present in 76% of cases. In the first stage, an "intact canal wall technique" (ICWT) was carried out in 44% and a "canal wall down technique" (CWDT) in 56%. A planned second stage was carried out in 76% of ICWT and 56% of CWDT. The incidence of residual cholesteatoma was 29% and the incidence of recurrent cholesteatoma was 11%. A third stage was carried out in 6 cases (11%) without residual or recurrent cholesteatoma. Finally a CWDT was performed in 65% and a ICWT in 35%. The hearing results were significantly better with ICWT but this was due to a better preoperative hearing level. Whatever the surgical technique, the hearing results were better in the presence of an intact stapes. The surgery was individualized. Although ICWT is our priority technique, it was feasible, in our experience, only in a minority of cases because of difficult ablation, insufficient eustachian tube function and very advanced sigmoid sinus or very low lying tegmen plate. Minimal postoperative cavity problems were encountered, even in children where in our experience the mastoidal pneumatisation is limited. PMID:9827188

    The Fontan surgery for single ventricle heart defects is a typical example of a clinical intervention in which patient-specific computational modeling can improve patient outcome: with the functional heterogeneity of the presenting patients, which precludes generic solutions, and the clear influence of the surgically-created Fontan connection on hemodynamics, it is acknowledged that individualized computational optimization of the post-operative hemodynamics can be of clinical value. A large body of literature has thus emerged seeking to provide clinically relevant answers and innovative solutions, with an increasing emphasis on patient-specific approaches. In this review we discuss the benefits and challenges of patient-specific simulations for the Fontan surgery, reviewing state of the art solutions and avenues for future development. We first discuss the clinical impact of patient-specific simulations, notably how they have contributed to our understanding of the link between Fontan hemodynamics and patient outcome. This is followed by a survey of methodologies for capturing patient-specific hemodynamics, with an emphasis on the challenges of defining patient-specific boundary conditions and their extension for prediction of post-operative outcome. We conclude with insights into potential future directions, noting that one of the most pressing issues might be the validation of the predictive capabilities of the developed framework.

    The use of high-level magnification (6-8x loupes magnification, or higher degrees of magnification provided by the surgical operating microscope), combined with head-mounted, coaxial lighting, may improve the ability of a dentist or dental hygienist to perform prophylaxis or scaling and root planing procedures, compared to the performance of these tasks using unaided vision or entry-level (2.5x) magnification, combined with overhead operatory lighting. A magnified view of the supragingival contours of a tooth surface facilitates visualizing the dimensions and curvature of the unseen sub-gingival tooth surfaces, which facilitates detection and removal of calculus that is located on these subgingival surfaces. Improved calculus removal ability may lead to better periodontal disease outcomes. PMID:24245463

    Narrow-diameter implants (NDIs) are increasingly produced and used in implant dentistry, especially since the introduction of new, more resistant materials. The objective of the present study was to evaluate the clinical performance of NDIs (3.3 mm) placed in thin alveolar crests. Twenty consecutive patients needing implant-supported fixed partial dentures and presenting an alveolar thickness ≤6 mm were treated with 1 or several NDIs. The surgical protocol was chosen according to the clinical situation: (1) flapless, (2) mini-cervical flap, (3) wide flap, (4) wide flap + guided bone regeneration (GBR). Implants were immediately loaded if the primary stability was higher than 20 Ncm. Implant survival and success, prosthodontic success rates, and patient-centered outcomes were evaluated after a follow-up period of 1 year. A total of 39 implants were placed in 20 patients, 12 and 27 implants in the anterior regions and in the posterior mandible, respectively. All but 1 implant reached an insertion torque higher than 20 Ncm and were loaded within 48 hours. The implant survival and success rates both reached 94.7%. The need for GBR was avoided in 60% of the implant sites. The mean peri-implant bone remodeling after a follow-up period of 1 year was -0.35 mm at the implant level. Peri-implant bone remodeling was higher in the posterior region, when the alveolar crest was thinner than 4 mm and GBR was required in addition. In conclusion, use of NDIs to restore partial edentation in sites with limited horizontal thickness seems to be an effective treatment option that prevented GBR in the majority of the present cases. Immediate provisionalization of NDIs does not seem to impair the results. PMID:24766161

    Full Text Available The laryngeal mask airway (LMA is a supraglottic airway management device. The LMA is preferred for airway management in paediatric patients for short duration surgical procedures. The recently introduced ProSeal (PLMA, a modification of Classic LMA, has a gastric drainage tube placed lateral to main airway tube which allows the regurgitated gastric contents to bypass the glottis and prevents the pulmonary aspiration. This study was done to compare the efficacy of ProSeal LMA with an endotracheal tube in paediatric patients with respect to number of attempts for placement of devices, haemodynamic responses and perioperative respiratory complications. Sixty children, ASA I and II, weighing 10-20 kg between 2 and 8 years of age group of either sex undergoing elective ophthalmological and lower abdominal surgeries of 30-60 min duration, randomly divided into two groups of 30 patients each were studied. The number of attempts for endotracheal intubation was less than the placement of PLMA. Haemodynamic responses were significantly higher (P<0.05 after endotracheal intubation as compared to the placement of PLMA. There were no significant differences in mean SpO 2 (% and EtCO 2 levels recorded at different time intervals between the two groups. The incidence of post-operative respiratory complications cough and bronchospasm was higher after extubation than after removal of PLMA. The incidence of soft tissue trauma was noted to be higher for PLMA after its removal. There were no incidences of aspiration and hoarseness/sore throat in either group. It is concluded that ProSeal LMA can be safely considered as a suitable and effective alternative to endotracheal intubation in paediatric patients for short duration surgical procedures.

  18. A Fluidic Cell Embedded Electromagnetic Wave Sensor for Online Indication of Neurological Impairment during Surgical Procedures

    International Nuclear Information System (INIS)

    Lactate is known to be an indicator of neurological impairment during aortic aneurysm surgery. It is suggested that cerebrospinal fluid removed during such surgery could provide useful information in this regard. Medical professionals find the prospect of online detection of such analytes exciting, as current practice is time consuming and leads to multiple invasive procedures. Advancing from the current laboratory based analysis techniques to online methods could provide the basis for improved treatment regimes, better quality of care, and enhanced resource efficiency within hospitals. Accordingly, this article considers the use of a low power fluidic system with embedded electromagnetic wave sensor to detect varying lactate concentrations. Results are promising over the physiological range of 0 − 20 mmol/L with a calibration curve demonstrating an R2 value > 0.98.

    The objective of this study was to evaluate an Er:YAG laser (ErL) application for periodontal regenerative surgery in angular bone defects at nine sites in six patients. Debridement was thoroughly performed using a combination of curettage with a Gracey-type curette and ErL irradiation at a panel setting of 70 mJ/pulse and 20 Hz with sterile saline spray. After applying an enamel matrix derivative and autogenous bone grafting, ErL was used to form a blood clot coagulation on the grafted bone surface at 50 mJ/pulse and 20 Hz without water spray for approximately 30 seconds. Twelve months after surgery the mean probing depth had improved from 6.2 mm to 2.0 mm, the mean clinical attachment level had reduced from 7.5 mm to 3.4 mm, and bleeding on probing had improved from (+) to (-). Mean intrabony defect depth decreased from 6.0 mm before surgery to 1.0 mm 12 months after surgery. A novel procedure for periodontal regenerative surgery applying ErL irradiation for thorough decontamination during debridement as well as blood coagulation following autogenous bone grafting seems to have achieved favorable and stable healing of periodontal pockets with significant clinical improvement and desirable regeneration of angular bone defects, including one-wall defects.

    Full Text Available Dental treatment performed in patients receiving oral anticoagulant drug therapy is becoming increasingly common in dental offices.The aim of oral anticoagulant therapy is to reduce blood coagulability to an optimal therapeutic range within which the patient is provided some degree of protection from thromboembolic events. This is achieved at the cost of a minor risk of haemorrhage. Frequently raised questions concern the safety and efficacy of the various anticoagulation regimens and their accompanying thromboembolic and bleeding risks relative to invasive dental procedures.The aim of this literature review is to evaluate the available evidence on the impact of anticoagulant medications on dental treatment and highlight certain patient management issues closely interrelated to various aspects of dental treatment. For that purpose literature search in the electronic database of Medscape, Pubmed-Medline, Science Direct, and EBSCO host, in the data base of Medical University Plovdiv and specialised published books in general medicine and dentistry was made.A total of 33 publications between 1995 and 2013 were identified: 12 review articles, 11 randomized controlled and non-randomised studies, 6 guidelines and practical guides, 1 meta-analysis and 3 specialised books.

    Intravenous propofol anesthesia is better than inhalational anesthesia for otologic surgery, but cost and intraoperative movement make this technique prohibitive. This study compares a propofol sandwich anesthetic with a total propofol or inhalational anesthetic for otologic surgery to determine which produces the best perioperative conditions and least expense. One hundred twenty patients undergoing ear surgery were randomly chosen to receive an anesthetic with either isoflurane (INHAL), total propofol (TPROP), or propofol used in conjunction with isoflurane (PSAND). Postoperative wakeup and the incidence and severity of nausea, vomiting, and pain were compared among groups. Antiemetic administration and discharge times from recovery and the hospital were also compared. The groups were similar, but anesthesia times were longer in the INHAL group. Emergence from anesthesia after PSAND or TPROP was more rapid than after INHAL. Recovery during the next 24 hours was associated with less nausea and vomiting with PSAND than with INHAL. The cost of the PSAND anesthetic was similar to that of INHAL, and both were less than TPROP. PSAND anesthesia may be similar to TPROP and better than INHAL for otologic procedures. PSAND was less expensive than TPROP and produced a similar recovery profile and antiemetic effect in the 24-hour period after surgery. PMID:10064647

    Full Text Available The vascularization of tissue engineered products represents a key issue in regenerative medicine which needs to be addressed before the translation of these protocols to the bedside can be foreseen. Here we propose a multistep procedure to prepare pre-vascularized three-dimensional (3D cardiac bio-substitutes using dynamic cell cultures and highly porous biocompatible gelatin scaffolds. The strategy adopted exploits the peculiar differentiation potential of two distinct subsets of adult stem cells to obtain human vascularized 3D cardiac tissues. In the first step of the procedure, human mesenchymal stem cells (hMSCs are seeded onto gelatin scaffolds to provide interconnected vessel-like structures, while human cardiomyocyte progenitor cells (hCMPCs are stimulated in vitro to obtain their commitment towards the cardiac phenotype. The use of a modular bioreactor allows the perfusion of the whole scaffold, providing superior performance in terms of cardiac tissue maturation and cell survival. Both the cell culture on natural-derived polymers and the continuous medium perfusion of the scaffold led to the formation of a densely packaged proto-tissue composed of vascular-like and cardiac-like cells, which might complete maturation process and interconnect with native tissue upon in vivo implantation. In conclusion, the data obtained through the approach here proposed highlight the importance to provide stem cells with complementary signals in vitro able to resemble the complexity of cardiac microenvironment.

  3. Is there possibility of radioinduced deterministic effect during procedures of cardiac catheterism in patients?

    International Nuclear Information System (INIS)

    In this work were presented 22 cases of radiation deterministic effect in patients submitted to catheterism procedures by means of X-fluoroscope. Evaluation of the results suggest that the most of patients receive potential skin entrance doses over 2 Gy and some of them may have received doses over 12 Gy. At these doses, radiation induced erythema, ulceration and necrosis are all possible complications if the same entrance skin surface is exposed for the duration of the procedure

    BACKGROUND: A eutectic mixture of lidocaine and prilocaine (EMLA) has been shown to be effective in reducing pain from needle sticks, including those associated with blood sampling and intravenous insertion. OBJECTIVE: To evaluate the effectiveness of EMLA cream applied before needle puncture for local anesthetic administration before minor surgical procedures in this double-blind, randomized, controlled, parallel-group study. MATERIALS AND METHODS: Patients were randomly assigned to receive EMLA or placebo cream (Aqueous) applied under an occlusive dressing. After the procedure, patients were asked to rate the needle prick and procedure pain on a visual analog scale (0=no pain; 10=maximum pain). RESULTS: A total of 94 minor surgical procedures (49 in EMLA and 45 in control) were performed. The mean needle-stick pain score in the EMLA group was significantly lower than in the control group (2.7 vs. 5.7, p<.001, Mann-Whitney U-test). There was also significantly lower procedure pain in the EMLA group than in the control group (0.83 vs. 1.86, p=.009). There were no complications associated with the use of EMLA. CONCLUSION: EMLA effectively reduces the preprocedural needle-stick pain and procedural pain associated with minor surgical procedures.

    The U.S. Occupational Safety and Health Administration (OSHA) estimates that half a million health-care workers are exposed to laser surgical smoke each year. The purpose of this study was to establish a methodology to (1) estimate emission rates of laser-generated air contaminants (LGACs) using an emission chamber, and to (2) perform a screening study to differentiate the effects of three laser operational parameters. An emission chamber was designed, fabricated, and assessed for performance to estimate the emission rates of gases and particles associated with LGACs during a simulated surgical procedure. Two medical lasers (Holmium Yttrium Aluminum Garnet [Ho:YAG] and carbon dioxide [CO2]) were set to a range of plausible medical laser operational parameters in a simulated surgery to pyrolyze porcine skin generating plume in the emission chamber. Power, pulse repetition frequency (PRF), and beam diameter were evaluated to determine the effect of each operational parameter on emission rate using a fractional factorial design. The plume was sampled for particulate matter and seven gas phase combustion byproduct contaminants (benzene, ethylbenzene, toluene, formaldehyde, hydrogen cyanide, carbon dioxide, and carbon monoxide): the gas phase emission results are presented here. Most of the measured concentrations of gas phase contaminants were below their limit of detection (LOD), but detectable measurements enabled us to determine laser operation parameter influence on CO2 emissions. Confined to the experimental conditions of this screening study, results indicated that beam diameter was statistically significantly influential and power was marginally statistically significant to emission rates of CO2 when using the Ho:YAG laser but not with the carbon dioxide laser; PRF was not influential vis-a-vis emission rates of these gas phase contaminants.

    Full Text Available INTRODUCTION: This analysis explores the association between elements of surgical efficiency in voluntary medical male circumcision (VMMC, quality of surgical technique, and the amount of time required to conduct VMMC procedures in actual field settings. Efficiency outcomes are defined in terms of the primary provider's time with the client (PPTC and total elapsed operating time (TEOT. METHODS: Two serial cross-sectional surveys of VMMC sites were conducted in Kenya, Republic of South Africa, Tanzania and Zimbabwe in 2011 and 2012. Trained clinicians observed quality of surgical technique and timed 9 steps in the VMMC procedure. Four elements of efficiency (task-shifting, task-sharing [of suturing], rotation among multiple surgical beds, and use of electrocautery and quality of surgical technique were assessed as explanatory variables. Mann Whitney and Kruskal Wallis tests were used in the bivariate analysis and linear regression models for the multivariate analyses to test the relationship between these five explanatory variables and two outcomes: PPTC and TEOT. The VMMC procedure TEOT and PPTC averaged 23-25 minutes and 6-15 minutes, respectively, across the four countries and two years. The data showed time savings from task-sharing in suturing and use of electrocautery in South Africa and Zimbabwe (where task-shifting is not authorized. After adjusting for confounders, results demonstrated that having a secondary provider complete suturing and use of electrocautery reduced PPTC. Factors related to TEOT varied by country and year, but task-sharing of suturing and/or electrocautery were significant in two countries. Quality of surgical technique was not significantly related to PPTC or TEOT, except for South Africa in 2012 where higher quality was associated with lower TEOT. CONCLUSIONS: SYMMACS data confirm the efficiency benefits of task-sharing of suturing and use of electrocautery for decreasing TEOT. Reduced TEOT and PPTC in high volume

    Full Text Available Background and Aims: Central venous catheters are in situ in most of the intensive care unit (ICU patients, which may be an alternative for determining acid-base status and can reduce complications from prolonged arterial cannulation. The aim of this study was to examine the reliability between adjusted central venous blood gas (aVBG and arterial blood gas (ABG samples for pH, partial pressure of carbon-di-oxide (pCO2, bicarbonate (HCO3−, base excess (BE and lactates in paediatric cardiac surgical ICU. Methods: We applied blood gas adjustment rule, that is aVBG pH = venous blood gas (VBG pH +0.05, aVBG CO2 = VBG pCO2 - 5 mm Hg from the prior studies. In this study, we validated this relationship with simultaneous arterial and central venous blood obtained from 30 patients with four blood sample pairs each in paediatric cardiac surgical ICU patients. Results: There was a strong correlation (R i.e., Pearson's correlation between ABG and aVBG for pH = 0.9544, pCO2 = 0.8738, lactate = 0.9741, HCO3− = 0.9650 and BE = 0.9778. Intraclass correlation co-efficients (ICCs for agreement improved after applying the adjustment rule to venous pH (0.7505 to 0.9454 and pCO2 (0.4354 to 0.741. Bland Altman showed bias (and limits of agreement for pH: 0.008 (−0.04 to + 0.057, pCO2: −3.52 (–9.68 to +2.65, lactate: −0.10 (−0.51 to +0.30, HCO3−: −2.3 (–5.11 to +0.50 and BE: −0.80 (−3.09 to +1.49. Conclusion: ABG and aVBG samples showed strong correlation, acceptable mean differences and improved agreement (high ICC after adjusting the VBG. Hence, it can be promising to use trend values of VBG instead of ABG in conjunction with a correction factor under stable haemodynamic conditions.

  9. Factors affecting the radiation dose to the lens of the eye during cardiac catheterization procedures

    International Nuclear Information System (INIS)

    Concern has been expressed about relatively high radiation doses to the lens of the eye received by the operator during cardiac catheterization studies. A study was undertaken to assess occupational doses received by cardiologists and to examine the factors that affect the individual's eye dose. Eighteen cardiologists working in five catheterization laboratories at three centres were included in the study. Their eye doses, workload and individual study details were monitored at each centre. Operating dose rates and scattered radiation were also measured for each unit to compare equipment performance. The study demonstrated that the relationships between the cardiologist's eye dose and factors such as the dose efficiency of the X-ray equipment, scattered dose rates, examination protocols and workload are complex and vary from centre to centre. Because of these variations general workload limits may be inaccurate and should only be used for general guidance when no direct measurements are available. Such limits should be verified by local measurements as soon as is practical. (Author)

  11. Determination of doses and cancer risk to paediatric and young adult patients undergoing plain radiographic and fluoroscopic guided surgical procedures

    International Nuclear Information System (INIS)

    Fifty paediatric and young adult patients who underwent plain radiographic and fluoroscopic procedures in the operating theatres of a selected orthopaedic hospital were investigated. Radiation Dose was measured using single chip TLD (LiF) held at the skin surface at the beam entrance site for scoliotic, kyphotic and kyphoscoliotic patients undergoing Posterior Spinal Fusion (single stage), Posterior Spinal Fusion (two stage), Growing Rod and Revision Posterior Spinal Fusion as well as patients undergoing Intramedullary Nailing of the Femur and Osteotomy of the lower Extremity. The radiographic equipment were working at self-consistencies. The readings from the TLD, with patient data and other relevant information from the equipment console were used in Monte Carlo program software (PCMXC 2.0) to estimate organ and effective doses as well as assess cancer risk. Mean effective dose from Posterior Spinal Fusion (single stage), Posterior Spinal Fusion (two stage), Growing Rod, Revision Posterior Spinal Fusion, Nailing of the Femur and Osteotomy of the lower Extremity were found to be 7.62 ± 0.84 mSv, 7.48 ± 1.0, 6.82 ± 0.99 mSv, 2.50 ± 0.27 mSv, 0.18 ± 0.09 mSv and 0.001 ± 0.6E4 mSv respectively. The ribs recorded the highest bony organ tissue whiles the breast recorded the highest soft tissue organ dose with Posterior Spinal Fusion (single stage) recording the highest of 25.55±2.81 mGy and 11.49±1.22 mGy. Comparison of paediatric and young adult effective dose showed a higher effective dose in paediatric. Risk of radiation exposure induced cancer death from any cancer were considered for all the procedures and growing rod recorded the highest with 0.0954 % for females and 0.0500% for males. Risk of lung cancer was prevalent in all surgical procedures considered for the study followed by other cancers. However risk of breast cancer was high in females and risk of colon cancer for males.

    A hybrid X-ray and magnetic resonance imaging system (XMR) has been proposed as an interventional guidance for cardiovascular catheterisation procedure. However, very few hospitals can benefit from the XMR system because of its limited availability. In this paper we describe a new guidance strategy for cardiovascular catheterisation procedure. In our technique, intra-operative patient position is estimated by using a chest surface reconstructed from a photogrammetry system. The chest surface is then registered with the same surface derived from pre-procedure magnetic resonance (MR) images. The catheterisation procedure can therefore be guided by a roadmap derived from the MR images. Patients were required to hold the breath at end expiration during MRI acquisition. The surface matching accuracy is improved by using a robust trimmed iterative closest point (ICP) matching algorithm, which is especially designed for incomplete surface matching. Compared to the XMR system, the proposed guidance strategy is low cost and easy to set up. Experimental data were acquired from 6 volunteers and 1 patient. The patient data were collected during an electrophysiology procedure. In 6 out of 7 subjects, the experimental results show our method is accurate in term of reciprocal residual error (range from 1.66m to 3.75mm) and constant (closed-loop TREs range from 1.49mm to 3.55mm). For one subject, trimmed ICP failed to find the optimal transform matrix (residual = 4.89, TRE = 9.32) due to the poor quality of the photogrammetry-reconstructed surface. More studies are being carried on in clinical trials.

    The hybrid approach to management of hypoplastic left heart syndrome (HLHS) was developed as an alternative to neonatal Norwood surgery, providing a less invasive initial palliation for HLHS. We describe our experience in extending the concept of the hybrid procedure to palliate neonates with anatomically compromised systemic arterial blood flow in a variety of congenital cardiac anomalies and supporting its application as first-line palliation in centers developing their HLHS programs. Retrospective review of patients undergoing therapy for HLHS at a single institution from June 2008 to December 2014 was performed. Subject demographics, clinical and procedural data, along with follow-up, were collected. Thirteen patients had initial hybrid palliation for HLHS during the time frame indicated at a median age of 8 days (range 1-29 days) and median weight of 3.4 kg (range 2.4-4.6 kg). Diagnoses included typical HLHS (n = 6), right-dominant unbalanced atrioventricular septal defect with arch hypoplasia (n = 4), double outlet right ventricle [subpulmonic VSD (n = 1) and intact ventricular septum (n = 1)] with hypoplastic transverse aortic arch and borderline left ventricular dimensions. Standard approach with bilateral pulmonary artery banding and ductal stenting was carried out in all thirteen patients. Two patients required two ductal stents at the time of index procedure. There were no intraprocedural complications. Median intubation length post-procedure was 4 days (range 1-74 days). Median hospital stay post-procedure was 47 days (range 15-270 days). The overall mortality rate on follow-up through comprehensive stage 2 over the 6-year experience was 38 % (5 out of 13). Of note, the mortality rate was significantly lower in the latter 3 years of the study period when the procedure was adopted as a primary palliation for HLHS (14 % or 1 out of 7) compared to the initial 3-year period when it was reserved for higher risk cohorts (67 % or 4 out of 6

    The aim of the study is to evaluate the therapeutic effect of a new surgical procedure, dumbbell-form resection (DFR), for hilar cholangiocarcinoma (HCCA) with severe jaundice. In DFR, liver segments I, IVb, and partial V above the right hepatic pedicle are resected.Hemihepatectomy is recognized as the preferred procedure; however, its application is limited in HCCAs with severe jaundice.Thirty-eight HCCA patients with severe jaundice receiving DFR and 70 receiving hemihepatectomy from January 2008 to January 2013 were included. Perioperative parameters, operation-related morbidity and mortality, and post-operative survival were analyzed.A total of 21.1% patients (8/38) in the DFR group received percutaneous transhepatic biliary drainage (PTBD), which was significantly <81.4% (57/70) in the hemihepatectomy group. The TBIL was higher in the DFR group at operation (243.7 vs 125.6 μmol/L, respectively). The remnant liver volume was significantly higher after DFR. The operation-related morbidity was significantly lower after DFR than after hemihepatectomy (26.3% vs 48.6%, respectively). None of the patients died during the perioperative period after DFR, whereas 3 died after hemihepatectomy. There was no difference in margin status, histological grade, lymph-node involvement, and distant metastasis between the 2 groups. The 1-, 3-, and 5-year survival rates after DFR (68.4%, 32.1%, and 21.4%, respectively) showed no significant difference with those after hemihepatectomy (62.7%, 34.6%, and 23.3%, respectively). Kaplan-Meier analysis indicated that overall survival and recurrence after DFR demonstrated no significant difference compared with hemihepatectomy.DFR appears to be feasible for selected HCCA patients with severe jaundice. However, its indications should be restricted. PMID:26765439

  15. Assessment of the intrapulmonary ventilation-perfusion distribution after the Fontan procedure for complex cardiac anomalies: Relation to pulmonary hemodynamics

    International Nuclear Information System (INIS)

    In 12 patients who underwent the Fontan procedure for complex cardiac anomalies, lung scanning with xenon-133 was performed to assess the intrapulmonary ventilation-perfusion distribution, and comparison was made with a control group. All data were then analyzed in relation to either pre- or postoperative pulmonary hemodynamic data. In ventilation scans, the intrapulmonary distribution in the right lung was almost normal. In perfusion scans, an abnormal increased upper to lower lobe perfusion ratio greater than the normal value found in the control group was noted in seven patients (58.3%). There was a significant correlation (p less than 0.02) between the upper to lower lobe perfusion ratio and postoperative pulmonary vascular resistance. Furthermore, this perfusion ratio correlated inversely with the preoperative (p less than 0.005) and postoperative (p less than 0.02) right pulmonary artery area index, defined as the ratio of cross-sectional area to the normal value. Of five patients with less than 90% arterial oxygen saturation, four showed an abnormal distribution of pulmonary blood flow greater than the normal perfusion ratio. No patient had evidence of a pulmonary arteriovenous fistula by the echocardiographic contrast study. These results suggest that abnormal distribution of pulmonary blood flow to the upper lung segment may develop in patients after the Fontan procedure, and that insufficient size of the pulmonary artery before operation and the consequent postoperative elevation of pulmonary vascular resistance may be responsible for this perfusion abnormality

  16. CHANGES OF INTERLEUKIN-6 AND RELATED FACTORS AS WELL AS GASTRIC INTRAMUCOSAL Ph DURING COLORECTAL AND ORTHOPAEDIC SURGICAL PROCEDURES

    Objective To investigate the changes of perioperative serum levels of interleukin-6 ( IL-6), C-reactive protein (CRP), and cortisol, as well as gastric intramucosal pH (pHi) and plasma lactate, aiming to compare systemic changes and tissue perfusion during colorectal and orthopaedic surgical procedures. Methods Twenty patients were randomly assigned to two groups, 10 cases of operation on vertebral canal, 10 cases of colorectal radical operation. Venous blood was drawn at 1 day before operation, 2, 4, and 6 hours following skin incision, and 1 day after operation, in order to measure serum IL-6, CRP, and cortisol, pHi and plasma lactate were also measured at the same time points. Results Serum concentrations of IL-6 and cortisol increased gradually following operation, reaching the peak value at 6 hours from the beginning of operation. CRP was not detectable until the first day after operation. Peak concentration of IL-6 had positive relationship with CRP. These variables changed more significantly in colorectal group than that in orthopaedic group (P < 0. 05). pHi decreased gradually, reaching the lowest level at 4 hours from the beginning of operation, and to more extent in colorectal group than that in orthopaedic group ( P < 0. 05 ).Conclusion IL-6 may reflect tissue damage more sensitively than CRP. Colorectal surgery might induce systemic disorder to more extent, in terms of immuno-endocrinal aspect as well as tissue perfusion, reflected with pHi.

    Full Text Available Experimentally induced periodontitis forms the basis for trials of novel drugs and therapeutics. Ketamine, an N- amino-D- aspartate (NMDA receptor antagonist is considered to be safe dissociative anesthetic agent. But, the literature on the use of Ketamine as an effective general anesthetic is conflicting. We had to determine, safe and effective dose range of intra-peritoneal Ketamine hydrochloride injection in Wistar albino rats for the placement of ligatures in the oral cavity. 50 rats of the age group (greater than 4 months and weight of160g-350g were selected for the study from the Department of Pharmacology, Yenepoya University, and Mangalore. Intraperitonial injection was administered using Tuberculin syringe. The optimal dose for each animal was tabulated and log dose was calculated. Nonlinear regression analysis was done. 95% confidence limit and ED50 was calculated from the graph was 101.9mg/kg (68.1-152.6mg/kg correlation coefficient was 0.4946.  Profound and effective anesthesia was obtained at a dose of 60mg/kg-275mg/kg. The dose range of Ketamine alone from 60-275mg/kg i.p.route produced profound reproducible anesthesia. Minor oral surgical procedures could be carried out without discomfort. Mortality and morbidity due to anesthesia was low.

    Background The World Health Organization (WHO) and the Joint United Nations Program on HIV/AIDS promote MC (male circumcision) as a key HIV prevention strategy where HIV prevalence and incidence are high and MC prevalence is low. In Zimbabwe, to achieve the 1.26 million circumcisions needed to be performed by 2015 to achieve optimal MC coverage, a new approach was needed. The primary objective of the current trial was to assess the performance (safety, procedure time, and cost) of the PrePex device compared to forceps-guided surgical circumcision. Methods and Findings This Phase II, randomized, open-label trial in Zimbabwe involved healthy, non-circumcised adult male volunteers who were randomly assigned to the PrePex device (n = 160) or surgical arm (n = 80). Three doctors and 4 nurses, all certified on both circumcision methods, performed the procedures. The PrePex device procedure involves a plastic ring with a rubber O-ring that necrotizes the foreskin to facilitate easy and minimally invasive removal. Total procedure time was the primary endpoint. Adverse event (AE) data were also gathered for 90 days post-procedure. All 80 participants in the surgical arm and 158 participants in the PrePex arm achieved complete circumcision. The total procedure time for the PrePex device was approximately one-third of the total surgical procedure (4.8 minutes, Standard Deviation [SD]: 1.2 versus 14.6 minutes; SD: 4.2; pcircumcision. The PrePex device has great potential for use in overburdened health systems and in resource-limited settings and is recommended for use in rapid scale-up of adult MC in Zimbabwe.

  13. CONTRAST INDUCED NEPHROPATHY - A STUDY OF 850 PATIENTS UNDERGOING CARDIAC CATHETERIZATION LABORATORY PROCEDURES

    Directory of Open Access Journals (Sweden)

    Priya SV

    2010-11-01

    Full Text Available Background: Contrast-induced nephropathy (CIN represents an increasing healthcare burden and challenge especially in the scenario of increasing frequency of diagnostic imaging and interventional procedures. Frequency of CIN varies widely depending on the population. There is paucity of data regarding CIN in our population. The risk of CIN is elevated and is of clinical importance in patients with estimated glomerular filtration rate (GFR 60 ml/mt and GFR 30 – 60 ml/mt. Patients who developed CIN were followed up with serum creatinine measurement on the 5th day post procedure. Results: Among 850 patients enrolled for the study, 15 patients were lost for follow-up. Of the rest 835 patients, 535(64% were having GFR > 60ml /mt and 300 (36% having GFR of 30-60 ml/mt. The procedure was coronary angiography in 795(95% patients and percutaneous coronary intervention (PCI in 40 (5% patients. CIN occurred in 5 patients (0.59 %. 3 of 300 patients in the group with GFR 30 – 60 ml/mt and 2 of 535 patients in the group with GFR > 60ml/mt had CIN (1% vs 0.4% (p value 0.260 NS. Among the 500 hypertensives in the study population, 3 (0.6% developed CIN. CIN was seen in 4 out of 635 diabetics (0.6%, where as it occurred in 1 out of 200 non diabetics (0.5% (p value 0.589 NS. 4 among 100 patients with LV dysfunction and 1 out of 735 patients with normal LV function developed CIN (4% vs 0.13% (p value 0.001 . Conclusions: Overall incidence of CIN is low in the study population. Even in the group with low GFR, incidence of CIN is low. Left ventricular dysfunction is the only risk factor predicting development of CIN.

  14. A Phase II Randomized Controlled Trial Comparing Safety, Procedure Time, and Cost of the PrePex™ Device to Forceps Guided Surgical Circumcision in Zimbabwe.

    Directory of Open Access Journals (Sweden)

    Full Text Available The World Health Organization (WHO and the Joint United Nations Program on HIV/AIDS promote MC (male circumcision as a key HIV prevention strategy where HIV prevalence and incidence are high and MC prevalence is low. In Zimbabwe, to achieve the 1.26 million circumcisions needed to be performed by 2015 to achieve optimal MC coverage, a new approach was needed. The primary objective of the current trial was to assess the performance (safety, procedure time, and cost of the PrePex device compared to forceps-guided surgical circumcision.This Phase II, randomized, open-label trial in Zimbabwe involved healthy, non-circumcised adult male volunteers who were randomly assigned to the PrePex device (n = 160 or surgical arm (n = 80. Three doctors and 4 nurses, all certified on both circumcision methods, performed the procedures. The PrePex device procedure involves a plastic ring with a rubber O-ring that necrotizes the foreskin to facilitate easy and minimally invasive removal. Total procedure time was the primary endpoint. Adverse event (AE data were also gathered for 90 days post-procedure. All 80 participants in the surgical arm and 158 participants in the PrePex arm achieved complete circumcision. The total procedure time for the PrePex device was approximately one-third of the total surgical procedure (4.8 minutes, Standard Deviation [SD]: 1.2 versus 14.6 minutes; SD: 4.2; p<0.00001. There were 2 AEs for 2 participants (rate of 1.3%, 95% Confidence Interval: 0.0025-4.53%, which were resolved with simple intervention. The AEs were device related, including 1 case of pain leading to device removal and 1 case of removal of the device.The trial supports previous studies' conclusions that the PrePex procedure is safe, quick, easy to apply, and effective in terms of procedure time as an alternative to traditional surgical circumcision. The PrePex device has great potential for use in overburdened health systems and in resource-limited settings and is

    Introduction Facial transplantation represents one of the most complicated scenarios in craniofacial surgery because of skeletal, aesthetic, and dental discrepancies between donor and recipient. However, standard off-the-shelf vendor computer-assisted surgery systems may not provide custom features to mitigate the increased complexity of this particular procedure. We propose to develop a computer-assisted surgery solution customized for preoperative planning, intraoperative navigation including cutting guides, and dynamic, instantaneous feedback of cephalometric measurements/angles as needed for facial transplantation. Methods We developed the Computer-Assisted Planning and Execution (CAPE) workstation to assist with planning and execution of facial transplantation. Preoperative maxillofacial computed tomography (CT) scans were obtained on 4 size-mismatched miniature swine encompassing 2 live face-jaw-teeth transplants. The system was tested in a laboratory setting using plastic models of mismatched swine, after which the system was used in 2 live swine transplants. Postoperative CT imaging was obtained and compared with the preoperative plan and intraoperative measures from the CAPE workstation for both transplants. Results Plastic model tests familiarized the team with the CAPE workstation and identified several defects in the workflow. Live swine surgeries demonstrated utility of the CAPE system in the operating room, showing submillimeter registration error of 0.6 ± 0.24 mm and promising qualitative comparisons between intraoperative data and postoperative CT imaging. Conclusions The initial development of the CAPE workstation demonstrated integration of computer planning and intraoperative navigation for facial transplantation are possible with submillimeter accuracy. This approach can potentially improve preoperative planning, allowing ideal donor-recipient matching despite significant size mismatch, and accurate surgical execution. PMID:24406592

  16. Evaluation of occupational dose from the special procedures guided by fluoroscopy: cardiac catheterism

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the dose received by health professionals in the hemodynamic sector of a university hospital in Sao Paulo city. A self-applied questionnaire was used to delineate the profile of health professionals, taking into account sociodemographic variables and variables related to the work with ionizing radiation. The assessment of occupational doses was performed by consulting of the individual dose records of the institution database from 2000 to 2009. A total of 240 records was evaluated, corresponding to 38 active professionals (2009), divided in different professional category: physician, nurses, radiologic technologists and nursing assistants. The annual doses were compared with the limits established by national regulatory authorities. Based on the effective doses received and recorded during the studied period, experimental measures were performed with TL dosimeters in five physicians to evaluate the equivalent dose, in the left hand, during hemodynamic procedures. In addition, the radioprotection measures adopted by health professionals were verified. This study allowed delineating the profile of medical staff that integrates the hemodynamic service as well as knowing the distribution of their doses in relation to limits over the years. (author)

  17. Evaluation of a real-time display for skin dose map in cardiac catheterisation procedures

    International Nuclear Information System (INIS)

    The purpose of this work was to validate a prototype designed to display skin dose maps in real time for clinicians that perform interventional cardiology procedures. Measurements using copper absorbers and three kinds of dosemeters (solid-state, radiochromic film and optically stimulated luminescence) were performed in a catheterisation laboratory. Some clinical results are also discussed. The system provides patient skin doses with acceptable accuracy, taking into account couch shifts, wedge compensation filters and collimation. The greatest source of uncertainty is that resulting from patient shape modelling. From a set of 374 patients recorded, it can be concluded that the peak skin dose (PSD) for patients with the same cumulative air kerma at the patient entrance reference point can be rather different. This real-time skin dose calculator has resulted easier to manage for measuring patient PSDs than other methods based on films or CR plates. As well as an improvement for patient safety, it could prove a useful training tool for clinicians. (authors)

    Purpose: In cardiac ablation therapy, accurate anatomic guidance is necessary to create effective tissue lesions for elimination of left atrial fibrillation. While fluoroscopy, ultrasound, and electroanatomic maps are important guidance tools, they lack information regarding detailed patient anatomy which can be obtained from high resolution imaging techniques. For this reason, there has been significant effort in incorporating detailed, patient-specific models generated from preoperative imaging datasets into the procedure. Both clinical and animal studies have investigated registration and targeting accuracy when using preoperative models; however, the effect of various error sources on registration accuracy has not been quantitatively evaluated. Methods: Data from phantom, canine, and patient studies are used to model and evaluate registration accuracy. In the phantom studies, data are collected using a magnetically tracked catheter on a static phantom model. Monte Carlo simulation studies were run to evaluate both baseline errors as well as the effect of different sources of error that would be present in a dynamicin vivo setting. Error is simulated by varying the variance parameters on the landmark fiducial, physical target, and surface point locations in the phantom simulation studies. In vivo validation studies were undertaken in six canines in which metal clips were placed in the left atrium to serve as ground truth points. A small clinical evaluation was completed in three patients. Landmark-based and combined landmark and surface-based registration algorithms were evaluated in all studies. In the phantom and canine studies, both target registration error and point-to-surface error are used to assess accuracy. In the patient studies, no ground truth is available and registration accuracy is quantified using point-to-surface error only. Results: The phantom simulation studies demonstrated that combined landmark and surface-based registration improved

    Full Text Available Introduction: Anaemia is associated with increased post-operative morbidity and mortality. We retrospectively assess the relationship between preoperative anaemia and in-hospital mortality in valvular cardiac surgical population. Materials and Methods: Data from consecutive adult patients who underwent valvular repair/ replacement at our institute from January 2010 to April 2014 were collected from hospital records. Anaemia was defined according to WHO criteria (hemoglobin <13g/dl for males and <12g/dl for females. 1:1 matching was done for anemic and non-anemic patients based on propensity for potentially confounding variables. Logistic regression was used to evaluate the relationship between anaemia and in-hospital mortality. MatchIt package for R software was used for propensity matching and SPSS 16.0.0 was used for statistical analysis. Results: 2449 patients undergoing valvular surgery with or without coronary artery grafting were included. Anaemia was present in 37.1% (33.91% among males & 40.88% among females. Unadjusted OR for mortality was 1.6 in anemic group (95% Confidence Interval [95% CI] - 1.041-2.570; p=0.033. 1:1 matching was done on the basis of propensity score for anaemia (866 pairs. Balancing was confirmed using standardized differences. Anaemia had an OR of 1.8 for mortality (95% CI- 1.042 to 3.094, P=0.035. Hematocrit of < 20 on bypass was associated with higher mortality. Conclusion: Preoperative anaemia is an independent risk factor associated with in-hospital mortality in patients undergoing valvular heart surgery.

  3. Rejection in the cardiac transplant

    International Nuclear Information System (INIS)

    Standard chest radiography remains the most frequent applied method for monitoring post surgical cardiac transplant patients. Evidence suggests that after the 1st month cardiac enlargement is indeed a useful indicator of rejection, sometimes being caused by pericardial effusion and/or changes in left ventricular mass. Opportunistic infections, either pulmonary lesions or mediastinal abscesses, as well as malignant tumours may all occur and require evaluation or exclusion. Conventional computed transmission tomography is an excellent technique for surveying the entire thorax relatively non-invasively and is recommended whenever pulmonary, cardiac or mediastinal changes are unexplained. Coronary arteriography with or without digital subtraction remains the definitive method for examining the coronary arteries. Left ventricular function can be evaluated with either angiography or other non-invasive methods including such techniques as echocardiography and nuclear medicine. More recently monoclonal antibody labels for antimyosin show promise for identifying rejection. Ultrafast CT scanning is now available in a number of centres. It allows millisecond cross-sectional cine-tomography of the heart as well as of the whole chest, and also provides 3-D quantitative analyses of end-diastolic and systolic function including regional wall thickening dynamics and estimations of myocardial mass. Right, as well as left-sided cardiac chambers, are demonstrated routinely during the same ultrafast CT procedure. MRI, like ultrafast CT, is a new technique still being explored. MRI as well as MR spectroscopy are regarded as diagnostic radiology procedures. (author). 32 refs.; 3 figs.; 3 tabs

    Full Text Available Cardiac hydatid disease is rare. We report on an uncommon hydatid cyst localized in the right ventricular wall, right atrial wall tricuspid valve left atrium and pericard. A 33-year-old woman was treated for cough, fever and chest pain. Cardiac echocardiograpic examination revealed a round tumor (5.8 x 4 cm in the right ventricular free wall and two smaller cysts behind that tumor. There were cysts in right atrial wall and tricuspidal valve as well. Serologic tests for hydatidosis were positive. Computed tomography finding was consistent with diagnosis of hydatid cyst in lungs and right hylar part. Surgical treatment was rejected due to great risk of cardiac perforation. Medical treatment with albendazole was unsuccessful and the patient died due to systemic hydatid involvement of the lungs, liver and central nervous system.

    Objective Pulmonnary vein stenosis (PVS) is a rare congenital disease. It leads to progressive pulmonary hyperten-sion and heart failure with a high mortality. PVS may be isolated or asaseiated with other cardiac malformtions. There were few litera- tores regarding surgical treatmenta and the timing for intervention. The aim of this article is to summarize the surgical treatment for PVS combined with other cardiac malformations. Methods Five patients were diagnosed as PVS. The accompanied cardiac malformations were: xtrocordia(n = 1), patent duetus arteriosuss(n = 2), ventricular septal defect(n = 4), atrial septal defect(n = 2), double- chambered right ventricle(n = 1), pulmonary arterial stenosis (n = 1), tricuspid valve insufficiency(n= 2), partial anomalous pulmo- nary venous connection(n = 1), persistent left superior vena cava(n = 1). The mean age was(8.5 4± 6.4) years. The mean body weight was(15.2 ± 6.3) kg. The mean gradient pressure through the stenotie pulmonary veins was(22.0 ± 6.2) mmHg. Nine stenotic pulmonary veins wore found, including 6 cristal stenosises located at venoatrial junetiom and 3 tubular stauosises outside of the lung. The surgical procedures included eristal stenosis ring resection (n=6) and two of them repaired additionally by "longitudinally open and transeversoly suture of the endomembrane" plasty method. Pulmonary veins repair used auto-pericardium (n= 1) and unitization of neighbonring pulmonary veins(n = 1), etc. Remits Cardiopulmonary bypass and aortic cross-clamp time were(129.2 ± 74.6) and (74.24±39.1) rain, respectively. All the petients had a satisfying honmdynmnic aud no death happened. The mean length of hos- pital stay after operation was (10±3) days. Follow-up waa completed in a duration of 6 month - 3 years. There was a trace residual shunt of VSD and PDA and Ⅱ degree auriculo-ventricular block happened in one patient. Residual stenosis was found by color ulltra- sonograph in a cristal stenosis case, whose

    The evidence regarding specific cardiac perception and discrimination, and its relationship to voluntary cardiac control, is critically reviewed. Studies are considered in three sections, depending on the method used to assess cardiac perception: questionnaire assessment, discrimination procedures, and heartbeat tracking. The heartbeat tracking procedure would appear to suffer least from interpretative difficulties. Recommendations are made regarding the style of analysis used to assess heartbeat perception in such tracking tasks. PMID:348240

    2010-01-01

    Virtual and augmented reality environments have been adopted in medicine as a means to enhance the clinician's view of the anatomy and facilitate the performance of minimally invasive procedures. Their value is truly appreciated during interventions where the surgeon cannot directly visualize the targets to be treated, such as during cardiac procedures performed on the beating heart. These environments must accurately represent the real surgical field and require seamless integration of pre- and intra-operative imaging, surgical tracking, and visualization technology in a common framework centered around the patient. This review begins with an overview of minimally invasive cardiac interventions, describes the architecture of a typical surgical guidance platform including imaging, tracking, registration and visualization, highlights both clinical and engineering accuracy limitations in cardiac image guidance, and discusses the translation of the work from the laboratory into the operating room together with typically encountered challenges.

    Full Text Available Aim: The aim of the present case series report is to illustrate a clinical technique and present the application of onepiece transmucosal implants in flapless surgical procedures, supporting full arch immediate prostheses. Materials and methods: A total of 294 implants (Xive TG, Friadent, Germany have been used to support full arch immediate prostheses, over the last six years and have been in function for at least one year. The surgical placement of five or more implants per case involved immediate extraction and intrasocket flapless placement, combined with minimal flap elevation in the areas of healed extraction sites (43 mandibular and 7 maxillary arches. In all cases immediate provisionalization followed. Detailed three-dimensional cone-beam localized volumetric tomography preceeded the surgical procedures. The delivery of the final ceramo-metal prostheses was accomplished within a 20 day period. Materials and methods: Results Six implants failed to osseointegrate. All other implants are still successfully bearing the final prosthesis for the time that they have been followed. Soft tissue reaction was favorable from both the biologic and esthetic point of view. Conclusion: The flapless placement of one piece implants into edentulous healed sites is a predictable procedure in the presence of abundance of supporting bone as confirmed by 3-D imaging. On the other hand, immediate extraction placement of one piece implants allows the engagement of sound bone located deeper into the socket and provides adequate mechanical support of the soft tissue architecture that is preserved predictably. In all cases the prosthetic procedures are accomplished without disturbing the hardsoft tissue interface as the abutment-prosthesis interface is coronally elevated by the virtual design of the implant.

    The physiological and psychological stress that brain tumor patients undergo during the entire surgical experience can considerably affect several aspects of their hospitalization. The purpose of this study was to examine the effects of live music therapy on quality of life indicators, amount of medications administered and length of stay for persons receiving elective surgical procedures of the brain. Subjects (N = 27) were patients admitted for some type of surgical procedure of the brain. Subjects were randomly assigned to either the control group receiving no music intervention (n = 13) or the experimental group receiving pre and postoperative live music therapy sessions (n = 14). Anxiety, mood, pain, perception of hospitalization or procedure, relaxation, and stress were measured using a self-report Visual Analog Scale (VAS) for each of the variables. The documented administration of postoperative pain medications; the frequency, dosage, type, and how it was given was also compared between groups. Experimental subjects live and interactive music therapy sessions, including a pre-operative session and continuing with daily sessions until the patient was discharged home. Control subjects received routine hospital care without any music therapy intervention. Differences in experimental pretest and posttest scores were analyzed using a Wilcoxon Matched-Pairs Signed-Rank test. Results indicated statistically significant differences for 4 of the 6 quality of life measures: anxiety (p = .03), perception of hospitalization (p = .03), relaxation (p = .001), and stress (p = .001). No statistically significant differences were found for mood (p > .05) or pain (p > .05) levels. Administration amounts of nausea and pain medications were compared with a Two-Way ANOVA with One Repeated Measure resulting in no significant differences between groups and medications, F(1, 51) = 0.03; p > .05. Results indicate no significant differences between groups for length of stay (t = .97

    Full Text Available Abstract Background Little is known about the effects of professional staffing on cancer surgical outcomes. The present study aimed to investigate the association between cancer surgical outcomes and physician/nurse staffing in relation to hospital volume. Methods We analyzed 131,394 patients undergoing lung lobectomy, esophagectomy, gastrectomy, colorectal surgery, hepatectomy or pancreatectomy for cancer between July and December, 2007–2008, using the Japanese Diagnosis Procedure Combination database linked to the Survey of Medical Institutions data. Physician-to-bed ratio (PBR and nurse-to-bed ratio (NBR were determined for each hospital. Hospital volume was categorized into low, medium and high for each of six cancer surgeries. Failure to rescue (FTR was defined as a proportion of inhospital deaths among those with postoperative complications. Multi-level logistic regression analysis was performed to examine the association between physician/nurse staffing and FTR, adjusting for patient characteristics and hospital volume. Results Overall inhospital mortality was 1.8%, postoperative complication rate was 15.2%, and FTR rate was 11.9%. After adjustment for hospital volume, FTR rate in the group with high PBR (≥19.7 physicians per 100 beds and high NBR (≥77.0 nurses per 100 beds was significantly lower than that in the group with low PBR ( Conclusions Well-staffed hospitals confer a benefit for cancer surgical patients regarding reduced FTR, irrespective of hospital volume. These results suggest that consolidation of surgical centers linked with migration of medical professionals may improve the quality of cancer surgical management.

We...... after cardiac surgery was low ejection fraction, high EuroSCORE, procedures other than isolated CABG, elongated time on ECC, low body mass index, diabetes mellitus and preoperatively elevated s-creatinine. Reoperated patients significantly had a greater increase in postoperative s-creatinine and higher...

  16. Postoperative necrotizing fasciitis of the thorax in cardiac surgery

    Directory of Open Access Journals (Sweden)

    Frota Filho José Dario

    2001-01-01

    Full Text Available Necrotizing fasciitis is a rare soft tissue infection and a life-threatening emergency, often fatal. Its incidence and management are described plentifully in the medical literature regarding the most common anatomical sites involved like the abdomen, lower and upper limbs, and perineum. However, available data and case reports of chest wall necrotizing fasciitis after thoracic procedures are scarce, mainly after major cardiac operations. We report and discuss a case of necrotizing fasciitis of the chest wall occurring in the immediate postoperative period of a cardiac procedure, and include a brief review of the concepts, pathophysiology, and treatment reported in the medical literature. We emphasize the need for early diagnosis and urgent and effective surgical debridement. Of importance is the fact that we have not found any references in the literature to cases similar or equal to the one we describe here, which occurred in the postoperative period of a cardiac procedure.

  17. Evaluation of a simple radionuclide procedure for left-to-right cardiac shunt measurement - correlation with earpiece densitometry and cardiac catheterization

    International Nuclear Information System (INIS)

    Measurement of shunts from systemic to pulmonary circulation using a simple radionuclide technique has been introduced at our department. A good bolus of the Technetium-99m sodium pertechnetate at a dose of 200 μCi/kg body weight (minimal dose 2 mCi) was injected by way of a scalp vein needle connected to a three-way stopcock, thus permitting immediate flushing of the radioactive bolus dose with physiologic saline solution. An IGE-400A gamma camera with a low-energy, high-sensitivity parallel hole collimator was used. The data were stored for analysis on a Star computer at a rate of 4 frames/second for a 40-second period. Twenty-three patients (aged 3-33 years) underwent first pass radionuclide angiography and cardiac catheterization to estimate the degree of systemic-to-pulmonary shunting (QP/QS) ratio). In 15 of these patients, another non-invasive method, earpiece densitometry (EPD), was done to determine the size of the shunt qualitatively. Fifteen healthy volunteers submitted to first pass studies comprised our control group. Out of the 23 patients with shunts, 15 had simple intra-cardiac septal defects (atrial or ventricular) or patent ductus arteriosus, and 8 had valvular lesions plus shunts. Compared with the oximetry data, EPD resulted in misclassification of 5 out of 15 patients in that left-to-right shunts were interpreted as moderate in 4, i.e. QP/QS 2:1, when in fact they were smaller. The correlation coefficient value of the first pass method for simple defect is r=0.89 (A=0.41 and B=0.85), for combined lesions it is r=0.94 (A=0.1 and B=1.1). The mean value for QP:QS in 15 normal subjects is 1.06:1 (SD=± 0.05). We conclude that first pass radionuclide angiography is a non-invasive and reliable method for determining QP/QS ratios. Unlike cardiac catheterization, it can be performed rapidly on an out-patient basis. (orig./TRV)

  18. Relationship between cardiac output and effective renal plasma flow in patients with cardiac disease

    1984-12-01

    The relationship between effective renal plasma flow (ERPF) and cardiac output was examined in 46 patients (22 with congestive heart failure and 24 following cardiac surgical procedures) by simultaneously measuring the global ERPF by the single-injection method and cardiac output by the thermodilution method. Of the patients in the heart-failure group, 21 also had pulmonary artery end diastolic pressure (PAEDP) recorded at the same time. ERPF and cardiac output were found to be related by the regression equations: cardiac output = 2.08 + 0.0065 ERPF (r, 080), with a SE of estimate of 0.81 l/min. ERPF and PAEDP were related by the regression equation: PAEDP = 42.02 - 0.0675 ERPF (r, 0.86), with a SE of estimate of 5.5 mm Hg. ERPF may be a useful noninvasive method of estimating cardiac output if it is known that no intrinsic kidney disease is present, and if the error of 0.81 l/min (1 SE of estimate) is within the range of clinical usefulness. The error is principally attributable to the determination of cardiac output by the thermodilution method.

  19. Surgical outcomes of 2041 consecutive laparoscopic gastrectomy procedures for gastric cancer: a large-scale case control study.

    Jian-Xian Lin

    Full Text Available BACKGROUND: Laparoscopic gastrectomy (LG for gastric cancer has increased in popularity due to advances in surgical techniques. The aim of this study is to validate the efficacy and safety of laparoscopic gastrectomy for gastric cancer compared with open gastrectomy (OG. METHODS: The study comprised 3,580 patients who were treated with curative intent either by laparoscopic gastrectomy (2,041 patients or open gastrectomy (1,539 patents between January 2005 and October 2013. The surgical outcomes were compared between the two groups. RESULTS: Laparoscopic gastrectomy was associated with significantly less blood loss, transfused patient number, time to ground activities, and post-operative hospital stay, but with similar operation time, time to first flatus, and time to resumption of diet, compared with the open gastrectomy. No significant difference in the number of lymph nodes dissected was observed between these two groups. The morbidity and mortality rates of the LG group were comparable to those of the OG group (13.6% vs. 14.4%, P = 0.526, and 0.3% vs. 0.2%, P = 0.740. The 3-year disease-free and overall survival rates between the two groups were statistically significant (P<0.05. According to the UICC TNM classification of gastric cancer, the 3-year disease-free and overall survival rates were not statistically different at each stage. CONCLUSIONS: Our single-center study of a large patient series revealed that LG for gastric cancer yields comparable surgical outcomes. This result was also true of local advanced gastric cancer (AGC. A well-designed randomized controlled trial comparing surgical outcomes between LG and OG in a larger number of patients for AGC can be carried out.

  20. Cardiac tumours in children

    Full Text Available Abstract Cardiac tumours are benign or malignant neoplasms arising primarily in the inner lining, muscle layer, or the surrounding pericardium of the heart. They can be primary or metastatic. Primary cardiac tumours are rare in paediatric practice with a prevalence of 0.0017 to 0.28 in autopsy series. In contrast, the incidence of cardiac tumours during foetal life has been reported to be approximately 0.14%. The vast majority of primary cardiac tumours in children are benign, whilst approximately 10% are malignant. Secondary malignant tumours are 10–20 times more prevalent than primary malignant tumours. Rhabdomyoma is the most common cardiac tumour during foetal life and childhood. It accounts for more than 60% of all primary cardiac tumours. The frequency and type of cardiac tumours in adults differ from those in children with 75% being benign and 25% being malignant. Myxomas are the most common primary tumours in adults constituting 40% of benign tumours. Sarcomas make up 75% of malignant cardiac masses. Echocardiography, Computing Tomography (CT and Magnetic Resonance Imaging (MRI of the heart are the main non-invasive diagnostic tools. Cardiac catheterisation is seldom necessary. Tumour biopsy with histological assessment remains the gold standard for confirmation of the diagnosis. Surgical resection of primary cardiac tumours should be considered to relieve symptoms and mechanical obstruction to blood flow. The outcome of surgical resection in symptomatic, non-myxomatous benign cardiac tumours is favourable. Patients with primary cardiac malignancies may benefit from palliative surgery but this approach should not be recommended for patients with metastatic cardiac tumours. Surgery, chemotherapy and radiotherapy may prolong survival. The prognosis for malignant primary cardiac tumours is generally extremely poor.

    Full Text Available Cardiac tumors are rare, and of these, primary cardiac tumors are even rarer. Metastatic cardiac tumors are about 100 times more common than the primary tumors. About 90% of primary cardiac tumors are benign, and of these the most common are cardiac myxomas. Approximately 12% of primary cardiac tumors are completely asymptomatic while others present with one or more signs and symptoms of the classical triad of hemodynamic changes due to intracardiac obstruction, embolism and nonspecific constitutional symptoms. Echocardiography is highly sensitive and specific in detecting cardiac tumors. Other helpful investigations are chest X-rays, magnetic resonance imaging and computerized tomography scan. Surgical excision is the treatment of choice for primary cardiac tumors and is usually associated with a good prognosis. This review article will focus on the general features of benign cardiac tumors with an emphasis on cardiac myxomas and their molecular basis.

    Full Text Available Purpose. To determine if the use of combined HLA matched limbal stem cells allograft with amniotic membrane transplantation (AMT is a safe and effective prophylactic surgical procedure to prevent corneal graft after penetrating keratoplasty (PK. Methods. We report the case of a 17 years old patient with a history of congenital glaucoma, trabeculectomy and multiple corneal graft rejections, presenting total limbal cell deficiency. To reduce the possibility of graft rejection in the left eye after a new PK, a two step procedure was performed. At first the patient underwent a combined HLA matched limbal stem cells allograft (LAT and AMT and then, 10 months later, a new PK. Results. During 12 months of follow-up, the corneal graft remained stable and smooth, with no sign of graft rejection. Conclusions. In our patient, the prophylactic use of LAT from HLA-matched donors and AMT before PK, may result in a better prognosis of corneal graft survival.

    Full Text Available AIM To compare the changes in blood glucose level associated with administration of adrenaline containing local anesthetic in diabetic and non-diabetic patients undergoing minor oral surgical procedures. METHODS AND MATERIAL The study included 150 well controlled diabetic patients and 150 non-diabetic healthy patients in age group of 40-60 years who underwent minor oral surgical procedures (trans alveolar extractions, alveoplasty and flap surgeries. Patients in both the group were administered 1.8ml of local anesthetic agent containing 1:100,000 adrenaline for inferior alveolar nerve block and 0.2 ml of anesthetic agent for long buccal nerve block. Blood glucose levels were assessed and compared during pre-operative and one hour post-operative period. STATISTICAL ANALYSIS The comparison of the random blood sugar levels preop and postop in both the groups were compared using paired t test and RBS levels between two groups were analysed using unpaired t test. P value less than 0.05 was considered statistically significant. RESULTS No statistically significant change in post-operative blood glucose level was noted between the diabetic and non-diabetic patients. CONCLUSION The study concluded that it is safe to administer local anesthetic containing 1:100,000 adrenaline in smaller volumes to well controlled diabetic patients.

    2015-07-01

    This work is focused on the detailed computer simulation of the key stages involved in a shape memory alloy (SMA) osteosynthesis bone stapling procedure. To this end, a recently developed three-dimensional constitutive SMA material model was characterized from test data of three simple uniaxial-isothermal-tension experiments for powder metallurgically processed nickel-rich NiTi (PM/NiTi-P) material. The calibrated model was subsequently used under the complex, thermomechanical loading conditions involved in the surgical procedure using the body-temperature-activated PM/NiTi-P bone staple. Our aim here is to assess the immediate and post-surgical performance characteristics of the stapling operation using the material model. From this study: (1) it was found that adequate compressive forces were developed by the PM/NiTi-P bone staple, with the tendency of this force to even increase under sustained thermal loading due to the intrinsic "inverse relaxation phenomena" in the SMA material, (2) the simulation results correlated well with those from experimental measurements, (3) the body-temperature-activated PM/NiTi-P staple was proved to be clinically viable, providing a stable clamping force needed for speedy coaptation of the fractured bones, and (4) these realistic assessments crucially depend on the use of suitable and comprehensive SMA material models.

    A review of the history of cardiac surgery around the world is made divided into three stages, the first since the beginning of humanity until 300 years BC; the second moment shows how comes the platform that would give the anatomical and functional bases of the cardiovascular system. This historic moment includes: 1. the description and analysis of the function of blood and its components; 2. the description of the normal and abnormal Anatomy of the human heart and its vessels; 3. the anatomic and functional correlation: Foundation of the deductive thinking, and 4. the anatomic and functional integration with the clinic. Finally, the third wave, which is living today, is the stage of the technological explosion that begins with procedures as thoracoscopic surgery with the concept of reducing surgical trauma through minimum approach surgery. Also the use of robotics to solve some of the alterations in the CC, another is hybrid procedures and finally the use of fetal cardiac surgery. PMID:27428342

  9. Minimally invasive cardiac surgery and transesophageal echocardiography

    2014-01-01

    Full Text Available Improved cosmetic appearance, reduced pain and duration of post-operative stay have intensified the popularity of minimally invasive cardiac surgery (MICS; however, the increased risk of stroke remains a concern. In conventional cardiac surgery, surgeons can visualize and feel the cardiac structures directly, which is not possible with MICS. Transesophageal echocardiography (TEE is essential during MICS in detecting problems that require immediate correction. Comprehensive evaluation of the cardiac structures and function helps in the confirmation of not only the definitive diagnosis, but also the success of surgical treatment. Venous and aortic cannulations are not under the direct vision of the surgeon and appropriate positioning of the cannulae is not possible during MICS without the aid of TEE. Intra-operative TEE helps in the navigation of the guide wire and correct placement of the cannulae and allows real-time assessment of valvular pathologies, ventricular filling, ventricular function, intracardiac air, weaning from cardiopulmonary bypass and adequacy of the surgical procedure. Early detection of perioperative complications by TEE potentially enhances the post-operative outcome of patients managed with MICS.

    Cardiac surgical procedures change respiratory mechanics, defecting in lung dysfunction. The physical therapists play an important role in the preparation and rehabilitation of individuals who are undergoing cardiac surgery, as they have a large quantity of techniques. The objective was to evaluate the effectiveness of breathing exercises with and without the use of devices, and respiratory muscle training in preoperative period of cardiac surgery in reducing postoperative pulmonary complications. Although there are controversies as to which technique to use, studies show the effectiveness of preoperative physiotherapy in the prevention and reduction of postoperative pulmonary complications.

  11. Fast tracking in paediatric cardiac anaesthesia : an update.

    Directory of Open Access Journals (Sweden)

    2002-01-01

    Full Text Available A care plan in which cardiac surgical patients progress quickly through the perioperative course to hospital discharge is often referred to as a Fast Track. Such care plans have been used extensively in adult cardiac patients but are also applicable to paediatric patients. Although no randomised controlled trials are available to document a reduction in hospital costs and avoidance of iatrogenic complications with paediatric fast tracks, many healthcare administrators encourage their use. Fast Track clinical guidelines usually include same day surgery, use of short- acting anaesthetic drugs, early extubation, effective pain management, and reduced intensive care unit stays. These protocols are certainly appropriate for simple procedures such as repair of atrial or ventricular septal defects or ligation of a patent ductus arteriosus. However, many paediatric cardiac anaesthesiologists consider that all paediatric patients without significant pulmonary or residual cardiac pathology can be managed using expedited postoperative protocols. Essential components in a "fast track" protocol include use of minimally invasive surgical techniques, modified ultrafiltration during cardiopulmonary bypass, transoesophageal echocardiography to evaluate the cardiac repair, and postoperative pain control. Using such techniques, 80-90% of paediatric patients can be extubated in the operating room or within 2-4 hours postoperatively. Despite the opinions of recognised experts, an appropriately sized and powered multicentre, controlled, randomised, prospective study is still needed to conclusively document the efficiency and effectiveness of the Fast Track in paediatric cardiac patients.

    OBJECTIVE Hospital readmission rate is increasingly used as a quality outcome measure after surgery. The purpose of this study was to establish, using a national database, the baseline readmission rates and risk factors for patient readmission after pediatric neurosurgical procedures. METHODS The American College of Surgeons National Surgical Quality Improvement Program-Pediatric database was queried for pediatric patients treated by a neurosurgeon between 2012 and 2013. Procedures were categorized by current procedural terminology (CPT) code. Patient demographics, comorbidities, preoperative laboratory values, operative variables, and postoperative complications were analyzed via univariate and multivariate techniques to find associations with unplanned readmissions within 30 days of the primary procedure. RESULTS A total of 9799 cases met the inclusion criteria, 1098 (11.2%) of which had an unplanned readmission within 30 days. Readmission occurred 14.0 ± 7.7 days postoperatively (mean ± standard deviation). The 4 procedures with the highest unplanned readmission rates were CSF shunt revision (17.3%; CPT codes 62225 and 62230), repair of myelomeningocele > 5 cm in diameter (15.4%), CSF shunt creation (14.1%), and craniectomy for infratentorial tumor excision (13.9%). The lowest unplanned readmission rates were for spine (6.5%), craniotomy for craniosynostosis (2.1%), and skin lesion (1.0%) procedures. On multivariate regression analysis, the odds of readmission were greatest in patients experiencing postoperative surgical site infection (SSI; deep, organ/space, superficial SSI, and wound disruption: OR > 12 and p 10 days (OR 1.411, p = 0.010), oxygen supplementation (OR 1.645, p = 0.010), nutritional support (OR 1.403, p = 0.009), seizure disorder (OR 1.250, p = 0.021), and longer operative time (per hour increase, OR 1.059, p = 0.029). CONCLUSIONS This study may aid in identifying patients at risk for unplanned readmission following pediatric neurosurgery

    Full Text Available Background: In today′s world, people are very much aware about their looks and personality. They are getting more concerned about the esthetics and thus are not ready to compromise the appearance of black holes, especially in the anterior region of the mouth. Various techniques like orthodontic correction, prosthetic veneers and various periodontal surgical methods have been used to cover these unaesthetic open embrasures. In the present study, a variant technique given by Beagle in 1992 was used to cover these open gingival embrasures. The technique uses a gingival flap from the labial aspect to close the open gingival embrasures thus solving the problem of black holes. Aims and Objectives: This clinical study was aimed to reconstruct the lost or blunted interdental papillae with gingival tissue for esthetic purpose and for maintaining oral health with the objective to determine the extent to which the procedure can revert the maxillary esthetics. Materials and Methods: The patients selected were those who were having a complaint of at least one black hole in the maxillary anterior region with grade ′0′ or ′1′ type of contour of interdental tissues. A total of 39 open embrasures were surgically closed using this technique. Various indices were taken pre-surgically and then again post surgically. Results: Plaque index and gingival index showed an initial increase in the scores at the end of 1 week. Later, there was a gradual fall till the end of the study. Bleeding index significantly increased at the end of 12 weeks ( P<0.001 but reduced to insignificant levels at the end of 24 weeks ( P<0.09. The sulcus depth increased by about 1.19 mm. There was improvement in the contour of interdental tissues in 51% of cases and in 38.46% the interdental papillae completely obliterated the open embrasures. Conclusion: The surgical technique used here for reconstruction of interdental papilla was fairly successful. However, use of bone grafts or

    Postoperative pulmonary dysfunction (PPD) is a frequent and significant complication after cardiac surgery. It contributes to morbidity and mortality and increases hospitalization stay and its associated costs. Its pathogenesis is not clear but it seems to be related to the development of a systemic inflammatory response with a subsequent pulmonary inflammation. Many factors have been described to contribute to this inflammatory response, including surgical procedure with sternotomy incision,...

    Pediatric cardiac surgery in developing countries is a major challenge. It is a challenge to employ evolving methods to cater to the surgical needs of a very large number of children with congenital heart defects while dealing with severe budgetary constraints, finding funding to maintain the program, and maintaining quality in the backdrop of constant turnover of trained medical, nursing, and other paramedical personnel. Choosing the best procedure to achieve maximum palliation at lower cost and, when possible, giving priority for one-stage corrective procedures, albeit at a higher risk, calls for practice modifications. Despite improved infrastructure and surgical skills in recent years, in some developing countries, logistics, affordability, late presentation, nutritional issues, staffing, and unfavorable economics continue to negatively influence the overall results compared to those of developed nations.

    Maintenance of a healthy periodontium is fundamental for the long term success of prosthetic restorations. Thus, prosthetic procedures with subgingival margins may affect the periodontal health if the distances between the junctional epithelium and supracrestal connective tissue attachment aren’t respected, or if there is insufficient space to maintain the health of the interproximal tissues, leading to gingival inflammation, connective tissue attachment loss and bone resorption.

    Full Text Available Surgical instruments are the group of tools used in surgical procedures. They are very expensive and sophisticated. Consequently, a standardized and meticulous care is essential; they should go through the decontamination, cleaning and sterilization process. These instruments are designed in order to provide surgeons with tools that help them to perform a basic surgical procedure; there are multiple variations and the design depends on their function. This paper aims at showing all surgical instruments that can be used in an operating room during surgery and are not generally included in the medical literature.

    Full Text Available INTRODUCTION A recombinant form of activated factor VII (rFVIIa is a haemostatic drug that is approved for use in haemophiliacs with antibodies to factor VIII or factor IX. Most recent studies and clinical experience have shown that rFVIIa (NovoSeven ®, Novo Nordisk A/S, Denmark gives extreme haemostatic effect in patients with severe "non-haemophilic" bleeding produced after trauma and major surgery. OBJECTIVE We present our preliminary experience of the use of rFVIIa in vascular surgery when conventional haemostatic measures are inadequate. METHOD There were 32 patients divided into five groups: Group I - 14 patients with ruptured abdominal aortic aneurysms; Group II - 10 patients with thoracoabdominal aortic aneurysms; Group III - 5 patients with retroperitoneal tumors involving great abdominal vessels; Group IV - 2 patients with portal hypertension and Group V - one patient with iatrogenic injury of brachial artery and vein during fibrinolytic treatment, because of myocardial infarction. RESULTS Clinical improvement was detected following treatment in 29 patients. Bleeding was successfully controlled as evidenced by improved haemodynamic parameters and decreased inotropic and transfusion requirements. CONCLUSION In vascular patients more liberal use of rFVIIa is limited, because no randomized controlled trial has proved its efficacy and safety in such patients; while also keeping in mind that the price of a 4.8 mg of rFVIIa is $4,080. We recommend the use of rFVIIa in vascular surgery only during and after operative treatment of thoracoabdominal aortic aneurysms, ruptured abdominal aortic aneurysms, retroperitoneal tumors involving the aorta and/or inferior vena cava, as well as portal hypertension, when non-surgical massive uncontrolled bleeding are present.

    Full Text Available The conventional medical management of emphysema using bronchodilators and anti-inflammatory agents has a limited benefit in patients having advanced hyperinflation of lungs due to destruction of elastic tissue. The natural course of Chronic Obstructive Pulmonary Disease (COPD has been shown to be altered by only smoking cessation and oxygen therapy so far. The lung volume reduction surgery is viewed as another modality to change the natural history of emphysema in recent years. For patients with more generalized emphysema, resection of lung parenchyma improves elastic recoil and chest wall mechanics. An extensive literature search has demonstrated that carefully selected patients of emphysema (i.e. upper lobe predominant disease, low exercise capacity and Forced Expiratory Volume in First Second (FEV1 and DLco and #8804; 20% of predicted receive benefits in terms of symptomatic improvement and physiologic response following Lung Volume Reduction Surgery (LVRS. The resurgent interest in LVRS and National Emphysema Treatment Trial findings for emphysema have stimulated a range of innovative methods, to improve the outcome and reduce complications associated with current LVRS techniques. These novel approaches include surgical resection with compression/banding devices, endobronchial blockers, sealants, obstructing devices and valves and endobronchial bronchial bypass approaches. Experimental data and preliminary results are becoming available for some of these approaches. Most of the published studies so far have been uncontrolled and unblinded. Overall, extensive research in the near future will help to determine the potential clinical applicability of these new approaches to the treatment of emphysema symptoms.

    Cardiac tumours in infancy are rare and are mostly benign with rhabdomyomas, fibromas and teratomas accounting for the majority. The presentation depends on size and location of the mass as they tend to cause cavity obstruction or arrhythmias. Most rhabdomyomas tend to regress spontaneously but fibromas and teratomas generally require surgical intervention for severe haemodynamic or arrhythmic complications. Other relatively rare cardiac tumours too are discussed along with an Indian perspect...

    OBJECTIVE To evaluate hospital administrative data to identify potential surgical site infections (SSIs) following primary elective total hip or knee arthroplasty. DESIGN Retrospective cohort study. SETTING All acute care facilities in Alberta, Canada. METHODS Diagnosis and procedure codes for 6 months following total hip or knee arthroplasty were used to identify potential SSI cases. Medical charts of patients with potential SSIs were reviewed by an infection control professional at the acute care facility where the patient was identified with a diagnosis or procedure code. For SSI decision, infection control professionals used the National Healthcare Safety Network SSI definition. The performance of traditional surveillance methods and administrative data-triggered medical chart review was assessed. RESULTS Of the 162 patients identified by diagnosis or procedure code, 46 (28%) were confirmed as an SSI by an infection control professional. More SSIs were identified following total hip vs total knee arthroplasty (42% vs16%). Of 46 confirmed SSI cases, 20 (43%) were identified at an acute care facility different than their procedure facility. Administrative data-triggered medical chart review with infection control professional confirmation resulted in a 1.1- to 1.7-fold increase in SSI rate compared with traditional surveillance. SSIs identified by administrative data resulted in sensitivity of 90% and specificity of 99%. CONCLUSION Medical chart review for cases identified through administrative data is an efficient supplemental SSI surveillance strategy. It improves case-finding by increasing SSI identification and making identification consistent across facilities, and in a provincial surveillance network it identifies SSIs presenting at nonprocedure facilities.

    2015-01-01

    Full Text Available Background: Transapical off-pump mitral valve intervention with neochord implantation for degenerative mitral valve disease have been recently introduced in the surgical practice. The procedure is performed under 2D-3D transesophageal echocardiography guidance. Methods: The use of 3D real-time transesophageal echocardiography provides more accurate information than 2D echocardiography only in all the steps of the procedure. In particular 3D echocardiography is mandatory for preoperative assessment of the morphology of the valve, for correct positioning of the neochord on the diseased segment , for the final tensioning of the chordae and for the final evaluation of the surgical result. Result and Conclusion: This article is to outline the technical aspects of the transesophageal echocardiography guidance of the NeoChord procedure showing that the procedure can be performed only with a close and continuous interaction between the anesthesiologist and the cardiac surgeon.

    It is widely accepted that the performance of the operating surgeon affects outcomes, and this has led to the publication of surgical results in the public domain. However, the effect of other members of the multidisciplinary team is unknown. We studied the effect of the anaesthetist on mortality after cardiac surgery by analysing data collected prospectively over ten years of consecutive cardiac surgical cases from ten UK centres. Casemix-adjusted outcomes were analysed in models that included random-effects for centre, surgeon and anaesthetist. All cardiac surgical operations for which the EuroSCORE model is appropriate were included, and the primary outcome was in-hospital death up to three months postoperatively. A total of 110 769 cardiac surgical procedures conducted between April 2002 and March 2012 were studied, which included 127 consultant surgeons and 190 consultant anaesthetists. The overwhelming factor associated with outcome was patient risk, accounting for 95.75% of the variation for in-hospital mortality. The impact of the surgeon was moderate (intra-class correlation coefficient 4.00% for mortality), and the impact of the anaesthetist was negligible (0.25%). There was no significant effect of anaesthetist volume above ten cases per year. We conclude that mortality after cardiac surgery is primarily determined by the patient, with small but significant differences between surgeons. Anaesthetists did not appear to affect mortality. These findings do not support public disclosure of cardiac anaesthetists' results, but substantially validate current UK cardiac anaesthetic training and practice. Further research is required to establish the potential effects of very low anaesthetic caseloads and the effect of cardiac anaesthetists on patient morbidity. PMID:26511481

    Conclusions: Patients with comorbidities of impaired renal function and/or impaired left ventricular systolic function are at high risk of developing SSI. There appears to be a relationship between SSIs in CABG patients and impaired renal or LV function (low ejection fraction. CABG with BIMA grafting could be performed safely even in diabetics. Future studies should consider further scrutiny of these and other factors in relation to SSIs in a larger surgical population.

    Postoperative cognitive dysfunction (POCD) is a debilitating surgical complication, with cardiac surgery patients at particular risk. To gain insight in the mechanisms underlying the higher incidence of POCD after cardiac versus non-cardiac surgery, systemic and central inflammatory changes, alterations in intraneuronal pathways, and cognitive performance were studied after cardiac and abdominal surgery in rats. Male Wistar rats were subjected to ischemia reperfusion of the upper mesenteric artery (abdominal surgery) or the left coronary artery (cardiac surgery). Control rats remained naïve, received anesthesia only, or received thoracic sham surgery. Rats were subjected to affective and cognitive behavioral tests in postoperative week 2. Plasma concentrations of inflammatory factors, and markers for neuroinflammation (NGAL and microglial activity) and the BDNF pathway (BDNF, p38MAPK and DCX) were determined. Spatial memory was impaired after both abdominal and cardiac surgery, but only cardiac surgery impaired spatial learning and object recognition. While all surgical procedures elicited a pronounced acute systemic inflammatory response, NGAL and TNFα levels were particularly increased after abdominal surgery. Conversely, NGAL in plasma and the paraventricular nucleus of the hypothalamus and microglial activity in hippocampus and prefrontal cortex on postoperative day 14 were increased after cardiac, but not abdominal surgery. Both surgery types induced hippocampal alterations in BDNF signaling. These results suggest that POCD after cardiac surgery, compared to non-cardiac surgery, affects different cognitive domains and hence may be more extended rather than more severe. Moreover, while abdominal surgery effects seem limited to hippocampal brain regions, cardiac surgery seems associated with more wide spread alterations in the brain. PMID:26867718

    Advances in robotic technology and imaging systems have enabled the broad application of minimally invasive techniques in cardiac surgery, including coronary artery bypass grafting and mitral valve repair in adults. In pediatric cardiac surgery, however, current robotic systems have been used primarily to facilitate thoracoscopic pediatric procedures on extracardiac lesions, such as ligation of patent ductus and division of vascular rings. The use of smaller instruments with sophisticated robotic wrists may make it possible to perform more complex extracardiac procedures even in young infants. Additionally, future technological improvements, including incorporation of tactile feedback, instrument tracking, and intracardiac imaging (such as real-time 3-dimensional echocardiography), may enable intracardiac robotic surgery to be performed in children. This article reviews the current and potential future applications of pediatric robotic surgery and the developmental work required to enable performance of these procedures, along with an overview of the problems associated with the use of current robotic surgical systems in children.

  1. Image-based view-angle independent cardiorespiratory motion gating and coronary sinus catheter tracking for x-ray-guided cardiac electrophysiology procedures

    International Nuclear Information System (INIS)

    Determination of the cardiorespiratory phase of the heart has numerous applications during cardiac imaging. In this article we propose a novel view-angle independent near-real time cardiorespiratory motion gating and coronary sinus (CS) catheter tracking technique for x-ray fluoroscopy images that are used to guide cardiac electrophysiology procedures. The method is based on learning CS catheter motion using principal component analysis and then applying the derived motion model to unseen images taken at arbitrary projections, using the epipolar constraint. This method is also able to track the CS catheter throughout the x-ray images in any arbitrary subsequent view. We also demonstrate the clinical application of our model on rotational angiography sequences. We validated our technique in normal and very low dose phantom and clinical datasets. For the normal dose clinical images we established average systole, end-expiration and end-inspiration gating success rates of 100%, 85.7%, and 92.3%, respectively. For very low dose applications, the technique was able to track the CS catheter with median errors not exceeding 1 mm for all tracked electrodes. Average gating success rates of 80.3%, 71.4%, and 69.2% were established for the application of the technique on clinical datasets, even with a dose reduction of more than 10 times. In rotational sequences at normal dose, CS tracking median errors were within 1.2 mm for all electrodes, and the gating success rate was 100%, for view angles from RAO 90° to LAO 90°. This view-angle independent technique can extract clinically useful cardiorespiratory motion information using x-ray doses significantly lower than those currently used in clinical practice. (paper)

    Full Text Available The study was intended to assess the results of multilevel soft tissue with bony corrective surgery as one sitting procedure on static deformities and contractures in lower limbs with patients of spastic cerebral palsy at free disabled surgical camps at Chhattisgarh state. In our study 30 patients were included with sixty percent male and forty percent female , within 4 - 16 years age group. Almost all patients had diplegia and only few patients had quadriplegia with grade 3 power in both upper limbs. Improvement in functional ability and locomotion of all operated patients were asse ssed by gross motor functional classification scale and with physical examination. Almost all patients who were operated in our study showed significant improvement in functional abilities and locomotion after surgery. All patients were maintaining functional abilities at follow up duration of 2 years (24 months, with 70%. excellent cases gait of patient were normal or mild spastic but they were walking without support , with 20% good cases gait of patients were spastic but patients comfortably walk with short knee braces and with 10% fair cases gait of patients were scissors but patients walked comfortably with long knee braces . Our study shows that, promising results can be obtained in spastic cerebral palsy patients with static deformities and cont ractures of joints in lower limbs with multilevel soft tissue and bony corrective surgery. We believe that it’s a team effort of the surgeon , paramedical and rehabilitation staff in postoperative period for the achievement of better results.

    Atrial fibrillation (AF) is the most frequent cardiac arrhythmia. Left atrial catheter ablation is currently performed to treat this disease. Several energy sources are used, such as radio-frequency or cryotherapy. The main target of this procedure is to isolate the pulmonary veins. However, significant complications caused by the invasive procedure are described, such as stroke, tamponade, and atrioesophageal fistula, and a second intervention is often needed to avoid atrial fibrillation recurrence. For these reasons, a minimally-invasive device allowing performance of more complex treatments is still needed. High-intensity focused ultrasound (HIFU) can cause deep tissue lesions without damaging intervening tissues. Left atrial ultrasound-guided transesophageal HIFU ablation could have the potential to become a new ablation technique. The goal of this study was to design and test a minimally-invasive ultrasound-guided transesophageal HIFU probe under realistic treatment conditions. First, numerical simulations were conducted to determine the probe geometry, and to validate the feasibility of performing an AF treatment using a HIFU mini-maze (HIFUMM) procedure. Then, a prototype was manufactured and characterized. The 18-mm-diameter probe head housing contained a 3-MHz spherical truncated HIFU transducer divided into 8 rings, with a 5-MHz commercial transesophageal echocardiography (TEE) transducer integrated in the center. Finally, ex vivo experiments were performed to test the impact of the esophagus layer between the probe and the tissue to treat, and also the influence of the lungs and the vascularization on lesion formation. First results show that this prototype successfully created ex vivo transmural myocardial lesions under ultrasound guidance, while preserving intervening tissues (such as the esophagus). Ultrasound-guided transesophageal HIFU can be a good candidate for treatment of AF in the future. PMID:24658718

  8. Three-dimensional reconstructed computed tomography-magnetic resonance fusion image-based preoperative planning for surgical procedures for spinal lipoma or tethered spinal cord after myelomeningocele repair. Technical note

    International Nuclear Information System (INIS)

    Surgical procedures for spinal lipoma or tethered spinal cord after myelomeningocele (MMC) repair are often difficult and complicated, because the anatomical structures can be deformed in complex and unpredictable ways. Imaging helps the surgeon understand the patient's spinal anatomy. Whereas two-dimensional images provide only limited information for surgical planning, three-dimensional (3D) reconstructed computed tomography (CT)-magnetic resonance (MR) fusion images produce clearer representations of the spinal regions. Here we describe simple and quick methods for obtaining 3D reconstructed CT-MR fusion images for preoperative planning of surgical procedures using the iPlan cranial (BrainLAB AG, Feldkirchen, Germany) neuronavigation software. 3D CT images of the vertebral bone were combined with heavily T2-weighted MR images of the spinal cord, lipoma, cerebrospinal fluid (CSF) space, and nerve root through a process of fusion, segmentation, and reconstruction of the 3D images. We also used our procedure called 'Image Overlay' to directly project the 3D reconstructed image onto the body surface using an light emitting diode (LED) projector. The final reconstructed 3D images took 10-30 minutes to obtain, and provided the surgeon with a representation of the individual pathological structures, so enabled the design of effective surgical plans, even in patients with bony deformity such as scoliosis. None of the 19 patients treated based on our 3D reconstruction method has had neurological complications, except for CSF leakage. This 3D reconstructed imaging method, combined with Image Overlay, improves the visual understanding of complicated surgical situations, and should improve surgical efficiency and outcome. (author)

  9. Infarct size in primary angioplasty without on-site cardiac surgical backup versus transferal to a tertiary center: a single photon emission computed tomography study

    International Nuclear Information System (INIS)

    Primary percutaneous coronary intervention (PCI) performed in large community hospitals without cardiac surgery back-up facilities (off-site) reduces door-to-balloon time compared with emergency transferal to tertiary interventional centers (on-site). The present study was performed to explore whether off-site PCI for acute myocardial infarction results in reduced infarct size. One hundred twenty-eight patients with acute ST-segment elevation myocardial infarction were randomly assigned to undergo primary PCI at the off-site center (n = 68) or to transferal to an on-site center (n = 60). Three days after PCI, 99mTc-sestamibi SPECT was performed to estimate infarct size. Off-site PCI significantly reduced door-to-balloon time compared with on-site PCI (94 ± 54 versus 125 ± 59 min, respectively, p 12%. Off-site PCI reduces door-to-balloon time compared with transferal to a remote on-site interventional center but does not reduce infarct size. Instead, pre-PCI TIMI 0/1 flow, anterior wall infarct localization, and development of Q-waves are more important predictors of infarct size. (orig.)

    Before non-cardiac surgery, evaluation of cardiac function is no frequent part of surgical treatment. European societies of anesthesiology and cardiology published consensus-guidelines in 2014 to present a reasonable approach for preoperative evaluation. This paper intends to differentiate the composite of perioperative risk and to display the guidelines methodical approach to handle it. Features to identify patients at risk from an ageing population with comorbidities, are the classification of surgical risk, functional capacity and risk indices. Application of diagnostic means, should be used adjusted to this risk estimation. Cardiac biomarkers are useful to discover risk of complications or mortality, that cannot be assessed by clinical signs. After preoperative optimization and perioperative cardiac protection, the observation of the postoperative period remains, to prohibit complications or even death. In consideration of limited resources of intensive care department, postoperative ward rounds beyond intensive care units are considered to be an appropriate instrument to avoid or recognize complications early to reduce postoperative mortality.

    úrgica.The surgical treatment of cancer of the middle rectum is still controversial. Several surgical procedures were retrospectively assessed in 90 patients operated from February 1990 to June 1997. Of these, 43 (47.7% patients were females and 47 (52.3% males. Age ranged from 20 to 90 years (mean,60.2 years. The main symptoms were tenesmus and straining, passage of blood and lost of weight. The time between the begining of the symptoms and the diagnosis ranged from two to 24 months (mean, 7.5 months. Abdominoperineal resection was done in 17 patients and the main complication was perineal dehiscence occuring in 47% of cases. One patient was submmited to total proctocolectomy. Hartmann procedure was done in 26 patients with 7.6% morbidity and 7.6% mortality caused by clinical complications. Twenty six patients had resection followed by anastomosis. 1n ten cases hand anastomosis had normal course without complications. In others 16, mechanical anastomosis was done with three dehiscences and one death related to clinical complications. Pull-through operation with coloanal anastomosis was done in eight patients with 50% complications, due to necrosis and retraction of the colon stump. One death occurred related to surgical complication. In 12 cases tumor resection was not done because the precarious condition of these patients. We conclude that the best procedure in cancer of the middle rectum depends of efficient evaluation considering the cell differentiation degree. the metastasis existence, the local condition of the tumor the clinical state of the patient and the experience of the surgeon.

    A project was undertaken to improve robotic surgical tools for telerobotic minimally invasive surgery. The major objectives were to reduce the size of the tools to permit new surgical procedures in confined spaces such as the heart and to improve control of surgical tools by locating positional sensors and actuators at the end effector rather than external to the patient as is currently the state of the technology. A new compact end-effector with wrist-like flexibility was designed. Positional sensors based on MEMS microfabrication techniques were designed.

    The goals of cardiac rehabilitation are (re-)conditioning and secondary prevention in patients with heart disease or an elevated cardiovascular risk profile. Rehabilitation is based on motivation through education, on adapted physical activity, instruction of relaxation techniques, psychological support and optimized medication. It is performed preferably in groups either in outpatient or inpatient settings. The Swiss working group on cardiac rehabilitation provides a network of institutions with regular quality auditing. Positive effects of rehabilitation programs on mortality and morbidity have been established by numerous studies. Although a majority of patients after cardiac surgery are being referred to rehabilitation, these services are notoriously underused after catheter procedures. PMID:26602848

    Full Text Available BACKGROUND: Pulmonary hypertension (PH is a frequent condition in patients with congenital heart diseases and left ventricle diseases. Preoperative PH causes higher mortality rate after heart surgery and adverse cardiac events. METHODS: We performed a prospective study which included 159 patients with preoperative PH that had undergone cardiac surgery between November 2008 and November 2011 in the Institute of Cardiovascular Diseases of Iaşi. 28 patients had class 1.4.4 pulmonary artery hypertension (due to congenital cardiac shunts and 131 patients had class 2 PH (due to left heart diseases. The preoperative echocardiography included: assessment of the left ventricular volume and ejection fraction, systolic pressure in the pulmonary artery; right ventricular end-diastolic diameter; right atrium area indexed for body surface area; pulmonary acceleration/ejection time ratio; TAPSE; determination of the severity of the associated tricuspid regurgitation; pericardial fluid presence. The primary endpoint was perioperative mortality; the secondary endpoints included: pericardial, pleural, hepatic or renal complications; the need for a new surgical procedure; postoperative mechanical ventilation > 24 hours; intensive care unit length of stay; postoperative inotropic support duration; the need for intra-aortic balloon pump; the need for pulmonary vasodilator drugs. RESULTS: The mortality rate was 2.51% and was statistically associated with NYHA IV preoperative class, the pulmonary acceleration/ejection time ratio, TAPSE, the presence of pericardial fluid, the indexed area of the right atrium and the concomitant CABG. Severe pulmonary hypertension(sPAP > 60 mmHg is associated with significant mortality rate increase, longer hospitalization in the intensive care unit, mechanical ventilation over 24 hours, lengthy inotropic support and renal, hepatic and pericardial complications. Residual PH and perioperative right ventricle dysfunction are common

    Surgical procedures often have the unfortunate side-effect of causing the patient significant trauma while accessing the target site. Indeed, in some cases the trauma inflicted on the patient during access to the target greatly exceeds that caused by performing the therapy. Heart disease has traditionally been treated surgically using open chest techniques with the patient being placed "on pump" - i.e. their circulation being maintained by a cardio-pulmonary bypass or "heart-lung" machine. Recently, techniques have been developed for performing minimally invasive interventions on the heart, obviating the formerly invasive procedures. These new approaches rely on pre-operative images, combined with real-time images acquired during the procedure. Our approach is to register intra-operative images to the patient, and use a navigation system that combines intra-operative ultrasound with virtual models of instrumentation that has been introduced into the chamber through the heart wall. This paper illustrates the problems associated with traditional ultrasound guidance, and reviews the state of the art in real-time 3D cardiac ultrasound technology. In addition, it discusses the implementation of an image-guided intervention platform that integrates real-time ultrasound with a virtual reality environment, bringing together the pre-operative anatomy derived from MRI or CT, representations of tracked instrumentation inside the heart chamber, and the intra-operatively acquired ultrasound images.

  6. Prospective evaluation of stress myocardial perfusion imaging for pre-operative cardiac risk assessment

    International Nuclear Information System (INIS)

    Full text: A prospective evaluation of patients who underwent stress myocardial perfusion imaging (MPI) to assess preoperative cardiac risk was undertaken. At the time of the scan patients were classified into 4 Clinical Risk groups (CR) based on known clinical data. On completion of the scan, the patient was then categorised into 4 Scan based Risk groups (SR), incorporating size of perfusion deficit, single versus multi-vessel disease and ejection fraction. Surgery at Austin and Repatriation Medical Centre within 6 months of scan and complications were identified using the hospital medical database. Major early cardiac events coded were death (cardiac related), myocardial infarction, unstable angina, acute pulmonary oedema, cardiac arrest, and urgent revascularisation. 208 patients have reached 6 months post-MPI scan. Of these 119 (57%) were identified as having surgery. Of the Scan Risk groups, 63% of normal, 57% of increased, and 47% of high and very high groups have had surgery. An abnormal scan is associated with a three-fold risk of cardiac complication (3.5% vs 11.3%). This is lower than most previous reports and may be due to higher representation of low risk surgical procedures (14% in this series), improved peri-operative care and/or the test result influence on management (suggested by decreasing surgical rate as SR estimate rose).

    Full Text Available Purpose To report the surgical technique, procedural outcomes, and feasibility of simultaneous bilateral Video Endoscopic Inguinal Lymphadenectomy (VEIL in the management of patients with indication for inguinal lymphadenectomy. Surgical Technique: VEIL was applied in all patients using the oncological landmarks (the adductor longus muscle medially, the sartorius muscle laterally and the inguinal ligament superiorly. A 1.5 cm incision was made 2 cm distally to the lower vertex of the femoral triangle. A second incision was made 2 cm proximally and 6 cm medially. Two 10 mm Hasson trocars were inserted in these incisions and the working space was insufflated with CO2 at 5-15 mmHg. The final trocar was placed 2 cm proximally and 6 cm laterally from the first port. Results: A total of 5 VEIL procedures in 3 patients were performed. Two patients underwent simultaneous bilateral VEIL while another underwent simultaneous bilateral surgery with VEIL on the right and open lymphadenectomy on the left side due to an enlarged node. All laparoscopic procedures were successfully performed without conversion and maintained the oncological templates. One lymphocele occurred in the patient who underwent the open procedure. None of the patients presented with skin necrosis after the procedure. Mean number of nodes retrieved was 6 from each side and 2 patients presented with positive inguinal nodes. After one year of follow-up no recurrences were observed. Conclusion: Simultaneous lymphadenectomy procedures are feasible. Improvement in operative and anesthesia time could decrease the morbidity associated with inguinal lymphadenectomy while maintaining the oncological principles.

    Computational modeling can provide critical insight into existing and potential new surgical procedures, medical or minimally-invasive treatments for heart failure, one of the leading causes of deaths in the world that has reached epidemic proportions. In this paper, we present our Abaqus/Standard-based pipeline to create subject-specific left ventricular models. We first review our generic left ventricular model, and then the personalization process based on magnetic resonance images. Identification of subject-specific cardiac material properties is done by coupling Abaqus/Standard to the python optimization library NL-Opt. Compared to previous studies from our group, the emphasis is here on the fully implicit solving of the model, and the two-parameter optimization of the passive cardiac material properties.

  10. Video-assisted thoracic surgery used in the cardiac re-synchronizartion therapy

    International Nuclear Information System (INIS)

    This is the first case of cardiac re-synchronization therapy (CRT) operated on the ''Hermanos Ameijeiras'' Clinical Surgical Hospital using video-assisted thoracic surgery. Patient is a man aged 67 presenting with a dilated myocardiopathy with severe left ventricular systolic dysfunction. At admission he showed a clinical picture of advanced cardiac insufficiency, thus, we considered the prescription of a CRT. After the failure of the percutaneous therapy for placing a electrode in a epicardiac vein of left ventricle, we decide the minimal invasive surgical approach. The epicardiac electrode implantation by thoracic surgery was a safe procedure without transoperative and postoperative complications. We have knowledge that this is the first time that a video-thoracoscopy in Cardiovascular Surgery is performed in Cuba. (author)

    Full Text Available Brianne L Dunn1, Walter E Uber1, John S Ikonomidis21Department of Pharmacy Services and 2Division of Cardiothoracic Surgery, Medical University of South Carolina, Charleston, South Carolina, USAAbstract: Coagulopathic bleeding may lead to increased morbidity and mortality after cardiac surgery. Topical bovine thrombin has been used to promote hemostasis after surgical procedures for over 60 years and is used frequently as a topical hemostatic agent in cardiac surgery. Recently, use of bovine thrombin has been reported to be associated with increased risk for anaphylaxis, thrombosis, and immune-mediated coagulopathy thought secondary to the production of antifactor V and antithrombin antibodies. In patients who develop bovine thrombin-induced immune-mediated coagulopathy, clinical manifestations may range from asymptomatic alterations in coagulation tests to severe hemorrhage and death. Patients undergoing cardiac surgical procedures may be at increased risk for development of antibodies to bovine thrombin products and associated complications. This adverse immunologic profile has led to the development of alternative preparations including a human and a recombinant thrombin which have been shown to be equally efficacious to bovine thrombin and have reduced antigenicity. However, the potential benefit associated with reduced antigenicity is not truly known secondary to the lack of long-term experience with these products. Given the potentially higher margin of safety and less stringent storage concerns compared to human thrombin, recombinant thrombin may be the most reasonable approach in cardiac surgery.Keywords: bovine thrombin, human thrombin, recombinant thrombin, immune-mediated coagulopathy, topical hemostatic agents, thrombin

    It is debated whether treating cancer patients in high-volume surgical centres can lead to improvement in outcomes, such as shorter length of hospital stay, decreased frequency and severity of post-operative complications, decreased re-admission, and decreased mortality. The dataset for this analysis was based on cancer registration and hospital discharge data and comprised information on 15,738 non-small-cell lung cancer patients resident and diagnosed in England in 2006-2010 and treated by surgical resection. The number of lung cancer resections was computed for each hospital in each calendar year, and patients were assigned to a hospital volume quintile on the basis of the volume of their hospital. Hospitals with large lung cancer surgical resection volumes were less restrictive in their selection of patients for surgical management and provided a higher resection rate to their geographical population. Higher volume hospitals had shorter length of stay and the odds of re-admission were 15% lower in the highest hospital volume quintile compared with the lowest quintile. Mortality risks were 1% after 30 d and 3% after 90 d. Patients from hospitals in the highest volume quintile had about half the odds of death within 30 d than patients from the lowest quintile. Variations in outcomes were generally small, but in the same direction, with consistently better outcomes in the larger hospitals. This gives support to the ongoing trend towards centralisation of clinical services, but service re-organisation needs to take account of not only the size of hospitals but also referral routes and patient access.

    Full Text Available Purpose: To study the surgical outcome of triple procedure as penetrating keratoplasty (PKP with conventional extra capsular cataract extraction (ECCE with posterior chamber intraocular lens (PCIOL implantation in patients with both central corneal opacity and advanced cataract at rural set up. Introduction: When corneal opacity and cataract present together then well-established and effective triple procedure is indicated. Prognosis for a clear graft is good in triple, as graft endothelium does not touch the hard nucleus which may occur in two steps or sequential surgery. It provides faster visual rehabilitation. Being single step procedure it reduces patient’s hospital stay, postoperative care and follows up visits. Methodology: In this hospital based observational , three years longitudinal study, we studied the surgical outcome of relatively rare one step triple procedure as PKP with conventional ECCE with PCIOL implantation in sulcus or in bag, in patients with both central corneal opacity and advanced cataract at rural set up. The outcome measures included graft clarity on slit lamp, postoperative unaided visual acuity with Snellen’s chart and the occurrence of postoperative complications after taking IEC permission and informed written consent in local language from study patients. Results: Out of 13 study patients mean age was 61.15yrs (Range50-80yrs. Follow up range was 9-34 months. At final follow up 9 patients (69.23% had clear grafts and 61.52% patients gained visual acuity >6/24. Graft failure was the most common post operative complication in 30.76% followed by Posterior capsular opacification (PCO in 15.38% patients which was treated well with YAG laser capsulotomy. Conclusion: Triple procedure gives good results in respect to graft clarity, unaided vision, and faster rehabilitation.

    Robotic surgical platforms were first developed with telesurgery in mind. Conceptualized by NASA and the military to provide surgical expertise to remote locations, some telesurgical success has been documented, but progress has been held back by communication bandwidth limitations. Telepresence surgery, where the surgeon is in proximity to the patient but is provided with an ergonomic console equipped with three-dimensional vision and autonomous control of wristed laparoscopic surgical instruments and energy sources, has shown efficacy first in cardiac and then urologic cancer surgery. Interest is currently focused on the application of this technology in the field of gynecology, with techniques being described to perform simple hysterectomy, myomectomy, tubal anastomosis, and pelvic reconstruction procedures. This article will review the application of robotic- and computer-assisted surgery in the specialty of gynecologic oncology. PMID:25484936

    The generation, storage, transfer, and representation of image data in radiology are standardized by DICOM. To cover the needs of image guided surgery or computer assisted surgery in general one needs to handle patient information besides image data. A large number of objects must be defined in DICOM to address the needs of surgery. We propose an analysis process based on Surgical Workflows that helps to identify these objects together with use cases and requirements motivating for their specification. As the first result we confirmed the need for the specification of representation and transfer of geometric models. The analysis of Surgical Workflows has shown that geometric models are widely used to represent planned procedure steps, surgical tools, anatomical structures, or prosthesis in the context of surgical planning, image guided surgery, augmented reality, and simulation. By now, the models are stored and transferred in several file formats bare of contextual information. The standardization of data types including contextual information and specifications for handling of geometric models allows a broader usage of such models. This paper explains the specification process leading to Geometry Mesh Service Object Pair classes. This process can be a template for the definition of further DICOM classes.

    Full Text Available Long procedure time and somewhat suboptimal results hinder the widespread use of catheter ablation of complex arrhythmias such as atrial fibrillation (AF. Due to lack of contrast differentiation between the area of interest and surrounding structures in a moving organ like heart, there is a lack of proper intraprocedural guidance using current imaging techniques for ablation. Cardiac image registration is currently under investigation and is in clinical use for AF ablation. Cardiac image registration, which involves integration of two images in the context of left atrium (LA, is intermodal, with the acquired image and the real-time reference image residing in different image spaces, and involves optimization, where one image space is transformed into the other. Unlike rigid body registration, cardiac image registration is unique and challenging due to cardiac motion during the cardiac cycle and due to respiration. This review addresses the basic principles of the emerging technique of registration and the inherent limitations as they relate to cardiac imaging and registration.

    Full Text Available Abstract Background An increasing number of septua- and octogenarians undergo cardiac surgery. Acute kidney injury (AKI still is a frequent complication after surgery. We examined the incidence of AKI and its impact on 30-day mortality. Methods A retrospective study between 01/2006 and 08/2009 with 299 octogenarians, who were matched for gender and surgical procedure to 299 septuagenarians at a university hospital. Primary endpoint was AKI after surgery as proposed by the RIFLE definition (Risk, Injury, Failure, Loss, End-stage kidney disease. Secondary endpoint was 30-day mortality. Perioperative mortality was predicted with the logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE. Results Octogenarians significantly had a mean higher logistic EuroSCORE compared to septuagenarians (13.2% versus 8.5%; p -1 × 1.73 m-2. In contrast, septuagenarians showed a slightly higher median body mass index (28 kg × m-2 versus 26 kg × m-2 and were more frequently active smoker at time of surgery (6.4% versus 1.6%, p The RIFLE classification provided accurate risk assessment for 30-day mortality and fair discriminatory power. Conclusions The RIFLE criteria allow identifying patients with AKI after cardiac surgery. The high incidence of AKI in septua- and octogenarians after cardiac surgery should prompt the use of RIFLE criteria to identify patients at risk and should stimulate institutional measures that target AKI as a quality improvement initiative for patients at advanced age.

    Full Text Available OBJECTIVE: To analyze parameters of respiratory system mechanics and oxygenation and cardiovascular alterations involved in weaning tracheostomized patients from long-term mechanical ventilation after cardiac surgery. METHODS: We studied 45 patients in their postoperative period of cardiac surgery, who required long-term mechanical ventilation for more than 10 days and had to undergo tracheostomy due to unsuccessful weaning from mechanical ventilation. The parameters of respiratory system mechanics, oxigenation and the following factors were analyzed: type of surgical procedure, presence of cardiac dysfunction, time of extracorporeal circulation, and presence of neurologic lesions. RESULTS: Of the 45 patients studied, successful weaning from mechanical ventilation was achieved in 22 patients, while the procedure was unsuccessful in 23 patients. No statistically significant difference was observed between the groups in regard to static pulmonary compliance (p=0.23, airway resistance (p=0.21, and the dead space/tidal volume ratio (p=0.54. No difference was also observed in regard to the variables PaO2/FiO2 ratio (p=0.86, rapid and superficial respiration index (p=0.48, and carbon dioxide arterial pressure (p=0.86. Cardiac dysfunction and time of extracorporeal circulation showed a significant difference. CONCLUSION: Data on respiratory system mechanics and oxygenation were not parameters for assessing the success or failure. Cardiac dysfunction and time of cardiopulmonary bypass, however, significantly interfered with the success in weaning patients from mechanical ventilation.

    Full Text Available Background: Paediatric patients often present with different painful conditions that require immediate surgical interventions. Despite a plethora of articles on the ketamine-propofol combination, comprehensive evidence regarding the suitable sedoanalgesia regime is lacking due to heterogeneity in study designs. Methods: This prospective, randomized, double-blind, active-controlled trial was conducted in 100 children, of age 3-14 years, American Society of Anesthesiologist physical status IE-IIE, posted for emergency short surgical procedures. Patients were randomly allocated to receive either 2 mL of normal saline (pre-induction plus calculated volume of drug from the 11 mL of ketamine-propofol solution for induction (group PK, n=50 or fentanyl 1.5 μg/kg diluted to 2 mL with normal saline (pre-induction plus calculated volume of drug from the 11 mL of propofol solution for induction (group PF, n=50. In both the groups, the initial bolus propofol 1 mg/kg i.v. (assuming the syringes contained only propofol, for simplicity was followed by adjusted infusion to achieve a Ramsay Sedation Scale score of six. Mean arterial pressure (MAP was the primary outcome measurement. Results: Data from 48 patients in group PK and 44 patients in group PF were available for analysis. Hypotension was found in seven patients (14.6% in group PK compared with 17 (38.6% patients in group PF (P=0.009. Intraoperative MAP was significantly lower in group PF than group PK when compared with baseline. Conclusion: The combination of low-dose ketamine and propofol is more effective and a safer sedoanalgesia regimen than the propofol-fentanyl combination in paediatric emergency short surgical procedures in terms of haemodynamic stability and lesser incidence of apnoea.

  8. Comparative Efficacy of Pulse-Spray Thrombolysis and Angioplasty Versus Surgical Salvage Procedures for Treatment of Recurrent Occlusion of PTFE Dialysis Access Grafts

    International Nuclear Information System (INIS)

    Purpose: To compare the efficacy of surgery versus pulse-spray thrombolysis and angioplasty in patients with recurrent thrombosis of polytetrafluoroethylene (PTFE) dialysis access grafts. Methods: We analyzed 96 consecutive interventions for thrombosed PTFE dialysis access grafts in 18 patients. Primary patency after thrombolysis and angioplasty (n= 25) was compared with primary patency following thrombectomy alone (n= 50) or thrombectomy followed by graft revision (n= 21) using life-table analysis. A Cox proportional hazards model that accounted for graft age and number of previous interventions was used to generate the relative risk for recurrent occlusion following therapy. Results: Life-table analysis showed that patency after thrombolysis and angioplasty was greater than that following thrombectomy alone (p= 0.02). After accounting for the age of the graft and the number of previous interventions (average six per patient), the relative risk for recurrent occlusion [3.0; 95% confidence intervals (CI): 1.5, 6.4] was greater for thrombectomy alone than for thrombolysis/angioplasty [0.6; CI = 0.3, 1.3]. The relative risks of repeat occlusion following thrombolysis/angioplasty [0.6; CI = 0.3, 1.3] and thrombectomy/surgical revision [1.0; CI = 0.5, 1.7] were similar. Conclusion: Outcome data from our retrospective study on recurrent thrombosis of PTFE dialysis access grafts suggest that thrombolysis/angioplasty is superior to thrombectomy alone, and equivalent to thrombectomy/surgical revision

    Full Text Available Aim We have studied epidemiology of in-hospital cardiac arrest, characteristics of organizing a reanimationand its,procedures as well as its documenting.Methods We analyzed all resuscitation procedure data where anesthesiology reanimation teams (RT providedcardiopulmonary resuscitation (CPR during one-year period. We included resuscitation attemptsthat were initiated outside the Department of Anesthesiology, excluding incidents in operation rooms andIntensive Care Unit (ICU. Data on every cardiac arrest and CPR were entered in a special form.Results During one-year period 87 CPR were performed. Victims of cardiac arrest were principallyelderly patients (age 60 – 80, mostly male (60%. Most frequent victims were neurological patients(42%, surgical patients (21% and neurosurgical patients (10%. The leading cause of cardiac arrestwas primary heart disease, following neurological diseases and respiration disorders of severe etiology.In over 90% cases CPR was initiated by medical personnel in their respective departments, RT arrivedwithin 5 minutes in 73,56% cases. Initially survival was 32%, but full recovery was accomplished in 4patients out of 87 (4,6%.Conclusion Victims of cardiac arrest are patients whose primary disease contributes to occurrence ofcardiorespiratory complications. High mortality and low percentage of full recovery can be explainedby characteristics of patients (old age, nature and seriousness of primary disease which significantly affectthe outcome of CPR. In some cases a question is raised whether to initiate the CPR at all. We wouldlike to point out that continous monitoring of potentially critical patients may prevent cardiorespiratoryincidents whereas the quality and success of CPR may be improved by training of staff and better technicalequipment on the relevant locations in the in the hospital where such incidents usually occur.

  13. Primary cardiac tumors

    International Nuclear Information System (INIS)

    Cardiac tumors happen to be among the less known pathologies without clear treatment standards. Even one decade ago most of the cardiac tumor diagnosis were made post mortem, and only reports of isolated cases could be found in the literature, showing the lack of interest in the investigation of these pathologies by cardiology and cardiovascular surgery specialists. With the development of echocardiography and of cardiovascular surgery, more cases of primary and metastatic cardiac tumors have been diagnosed. Many cases have been treated by palliative or curative surgical interventions, thus increasing the reports in the world literature and the experience in this field, and pointing out the real incidence of these pathologies, not being as bizarre as it had been considered. a revision of the literature will be made, in which the frequency and the suggested interventions will be reported, as well as the cases of cardiac pathology in two cardiovascular centers of the country known by the author. The echocardiographic, pathologic and histological characteristics of the representative cases will be presented, without a greater evidence level, due to the problem's incidence and the few cases reported by these centers

    In 1988, the New York State Health Commissioner was confronted with hospital-level data demonstrating very large, multiple-year, interhospital variations in short-term mortality and complications for cardiac surgery. The concern with the extent to which these differences were due to variations in patients' pre-surgical severity of illness versus hospitals' quality of care led to the development of clinical registries for cardiac surgery in 1989 and for percutaneous coronary interventions in 1992 in New York. In 1990, the Department of Health released hospitals' risk-adjusted cardiac surgery mortality rates for the first time, and shortly thereafter, similar data were released for hospitals and physicians for percutaneous coronary interventions, cardiac valve surgery, and pediatric cardiac surgery (only hospital data). This practice is still ongoing. The purpose of this communication is to relate the history of this initiative, including changes or purported changes that have occurred since the public release of cardiac data. These changes include decreases in risk-adjusted mortality, cessation of cardiac surgery in New York by low-volume and high-mortality surgeons, out-of-state referral or avoidance of cardiac surgery/angioplasty for high-risk patients, alteration of contracting choices by insurance companies, and modifications in market share of cardiac hospitals. Evidence related to these impacts is reviewed and critiqued. This communication also includes a summary of numerous studies that used New York's cardiac registries to examine a variety of policy issues regarding the choice and use of cardiac procedures, the comparative effectiveness of competing treatment options, and the examination of the relationship among processes, structures, and outcomes of cardiac care.

  15. Catheters, wires, tubes and drains on postoperative radiographs of pediatric cardiac patients: the whys and wherefores

    International Nuclear Information System (INIS)

    Surgical treatment of congenital heart disease has advanced dramatically since the first intracardiac repairs in the mid-20th century. Previously inoperable lesions have become the focus of routine surgery and patients are managed successfully in intensive care units around the world. As a result, increasing numbers of postoperative images are processed by departments of radiology in children's hospitals. It is important that the radiologist accurately documents and describes the catheters, wires, tubes and drains that are present on the chest radiograph. This article reviews the reasons for the placement and positioning of perioperative equipment in children who have surgical repair of atrial septal defect, ventricular septal defect or transposition of the great arteries. Also included are a brief synopsis of each cardiac anomaly, the surgical procedure for its correction, and an in-depth discussion of the postoperative chest radiograph including illustrations of catheters, wires, tubes and drains.

    Peter Nordbeck

    Full Text Available BACKGROUND: Surgical procedures in small animal models of heart disease might evoke alterations in cardiac morphology and function. The aim of this study was to reveal and quantify such potential artificial early or long term effects in vivo, which might account for a significant bias in basic cardiovascular research, and, therefore, could potentially question the meaning of respective studies. METHODS: Female Wistar rats (n = 6 per group were matched for weight and assorted for sham left coronary artery ligation or control. Cardiac morphology and function was then investigated in vivo by cine magnetic resonance imaging at 7 Tesla 1 and 8 weeks after the surgical procedure. The time course of metabolic and inflammatory blood parameters was determined in addition. RESULTS: Compared to healthy controls, rats after sham surgery showed a lower body weight both 1 week (267.5±10.6 vs. 317.0±11.3 g, n<0.05 and 8 weeks (317.0±21.1 vs. 358.7±22.4 g, n<0.05 after the intervention. Left and right ventricular morphology and function were not different in absolute measures in both groups 1 week after surgery. However, there was a confined difference in several cardiac parameters normalized to the body weight (bw, such as myocardial mass (2.19±0.30/0.83±0.13 vs. 1.85±0.22/0.70±0.07 mg left/right per g bw, p<0.05, or enddiastolic ventricular volume (1.31±0.36/1.21±0.31 vs. 1.14±0.20/1.07±0.17 µl left/right per g bw, p<0.05. Vice versa, after 8 weeks, cardiac masses, volumes, and output showed a trend for lower values in sham operated rats compared to controls in absolute measures (782.2±57.2/260.2±33.2 vs. 805.9±84.8/310.4±48.5 mg, p<0.05 for left/right ventricular mass, but not normalized to body weight. Matching these findings, blood testing revealed only minor inflammatory but prolonged metabolic changes after surgery not related to cardiac disease. CONCLUSION: Cardio-thoracic surgical procedures in experimental myocardial infarction

    Full Text Available Paediatric cardiac anaesthesia involves anaesthetizing very small children with complex congenital heart disease for major surgical procedures. The unique nature of this patient population requires considerable expertise and in-depth knowledge of the altered physiology. There have been several developments in the last decade in this subspecialty that has contributed to better care and improved outcome in this vulnerable group of patients. The purpose of this review is to present some of the recent advances in the anesthetic management of these children from preoperative evaluation to postoperative care. This article reviews the role of magnetic resonance imaging and contrast-enhanced magnetic resonance angiography in preoperative evaluation, the use of ultrasound to secure vascular access, the use of cuffed endotracheal tubes, the optimal haematocrit and the role of blood products, including the use of recombinant factor VIIa. It also deals with the advances in technology that have led to improved monitoring, the newer developments in cardiopulmonary bypass, the use of centrifugal pumps and extracorporeal membrane oxygenation and the role of DHCA. The role of new drugs, especially the α-2 agonists in paediatric cardiac anesthetic practice, fast tracking and effective postoperative pain management have also been reviewed.

    2016-01-01

    Full Text Available A promising open inguinal hernia operation called Onstep was developed in 2005. The technique is without sutures to the surrounding tissue, causing minimal tension. A specific mesh is used with a memory recoil ring in the border, which may cause pain superficial to the lateral part of the mesh for slender patients. The aim of this study was to illustrate an easy procedure that alleviates/removes the pain. A male patient had persistent pain six months after the Onstep operation and therefore had a ring removal operation. The procedure is presented as a video and a protocol. At the eleven-month follow-up, the patient was free of pain, without a recurrence. It is advised to wait some months after the initial hernia repair before removing the ring, since the mesh needs time to become well integrated into the surrounding tissue. The operation is safe and easy to perform, which is demonstrated in a video.

    Simulation in surgical training is playing an increasingly important role as postgraduate medical education programs navigate an environment of increasing costs of education, increased attention on patient safety, and new duty hour restrictions. In obstetrics and gynecology, simulation has been used to teach many procedures; however, it lacks a standardized curriculum. Several different simulators exist for teaching various routes and aspects of hysterectomy. This article describes how a formal framework of increasing levels of competencies can be applied to simulation in teaching the procedure of hysterectomy. PMID:27521885

    Conclusion. This type of tachycardia following after an atrial fibrillation surgery may be considered as a failing transmural myocardial damage during the procedure. The catheter method can be used succesfully unless there are no effects of antiarrhythmic therapy. The catheter method enables not only to verify the disconnection between the left atrial pulmonary veins and left atrium myocardium but also to perform the ablation in zones of the atrial myocardium that are anatomic substrates of post surgery tachyarrhythmias.

    2013-07-01

    Full Text Available The Cox maze procedure developed originally in 1987 by Dr James Cox has evolved from a “cut and sew” surgical procedure, where the maze was applied using multiple surgical cuts, to an extensive use of surgical ablation technology where ablation lesions are placed with alternative energy sources (radiofrequency, cryothermy, microwave, and high-frequency ultrasound. Furthermore, the procedure has changed from a median sternotomy approach only to one that can be performed minimally invasively and robotically. The purpose of this paper is to review the current available technology for the ablation of atrial fibrillation as well as the different procedural approaches for the surgical ablation of atrial fibrillation.

    1986-01-01

    The lipid composition of pulmonary surfactant, ependymal cells and pulmonary tissue after surgery on the thorax in dogs was determined. 24 hrs after removal of one lung, in the other one there occurred changes in the quantity of respective classes of phospholipids of the pulmonary surfactant, manifesting themselves by a considerable drop in the amount of phosphatidylcholine (by 25%), phosphatidylethylamine (by 47%), phosphatidylglycerol (by 98%) and phosphatidylcholine: sphingomyelin ratio (by 63%), as well as by a rise in the amount of lysophosphatidylcholine (by 83%), phosphatidylserine (by 54%) and sphingomyelin (by 25%). In dogs receiving betamethasone in the post-operative period the changes were less intense: the amount of phosphatidylcholine decreased by 15%, phosphatidylethanolamine by 29%, phosphatidylglycerol by 94% and phosphatidylcholine: sphingomyelin ratio by 63%. The amount of lysophosphatidylcholine increased by 26.7%, phosphatidylserine by 29.1% and sphingomyelin by 22.2%. Similar changes were observed in the phospholipids of lining cells, while changes in the composition of phospholipids of pulmonary tissue in most cases appeared insignificant. Insignificant, too, were changes in the composition of neutral lipids of the tissular fractions examined. The described changes in dogs not receiving betamethasone correspond to those found in man in the course of acute respiratory insufficiency syndrome. Betamethasone was found to exert a protective effect on the phospholipids of pulmonary surfactant, soothing the biochemical changes brought about by surgical removal of one lung. PMID:3325943

    Relationships between affect intensity and basal, evoked, and perceived cardiac arousal were investigated in 3 experiments. Affect intensity was assessed using Larsen and Diener's (1987) Affect Intensity Measure (AIM). Cardiac arousal was evoked with exercise in the 1st study and with mental arithmetic in the 2nd and 3rd. Perceived cardiac arousal was measured under optimal conditions using a standard heartbeat discrimination procedure. Women as a group scored higher on the AIM. Affect intensity was unrelated to basal or evoked cardiac arousal and was negatively related to perceived cardiac arousal in all 3 studies. Data suggest that affect intensity, although unrelated to actual physiological arousal, is negatively related to the accuracy with which individuals perceive their own arousal. Results are discussed within the context of an expanded arousal-regulation model (Blascovich, 1990). PMID:1494983

    Fast-track extubation is an established safe practice in pediatric congenital heart disease (CHD) surgical patients. On table extubation (OTE) in acyanotic CHD surgical patients is well established with validated safety profile. This practice is not yet reported in tetralogy of Fallot (TOF) cardiac surgical repair patients in developing countries. Evidence suggests that TOF total correction patients should be extubated early, as positive pressure ventilation has a negative impact on right ventricular function and the overall increase in post-TOF repair complications such as low cardiac output state and arrhythmias. The objective of the case series was to determine the safety and feasibility of OTE in elective TOF total correction cardiac surgical patients with an integrated team approach. To the best of our knowledge, this is the first reported case series. A total of 8 elective male and female TOF patients were included. Standard anesthetic, surgical and perfusion techniques were used in these procedures. All patients were extubated in the operating room safely without any complications with the exception of one patient who continued to bleed for 3 h of postextubation at 2-3 ml/kg/h which was managed with transfusion of fresh frozen plasma at 15 mL/kg, packed red blood cells 10 mL/kg and bolus of transamine at 20 mg/kg. Apart from better surgical and bypass techniques, the most important factor leading to successful OTE was an excellent analgesia. On the basis of the case series, it is suggested to extubate selected TOF cardiac surgery repair patients on table safely with integrated multidisciplinary approach. PMID:25849700

    Full Text Available Near-infrared spectroscopy (NIRS is used to monitor regional cerebral oxygenation (rScO2 during cardiac surgery but is less established during non-cardiac surgery. This systematic review aimed i to determine the non-cardiac surgical procedures that provoke a reduction in rScO2 and ii to evaluate whether an intraoperative reduction in rScO2 influences postoperative outcome. The PubMed and Embase database were searched from inception until April 30, 2013 and inclusion criteria were intraoperative NIRS determined rScO2 in adult patients undergoing non-cardiac surgery. The type of surgery and number of patients included were recorded. There was included 113 articles and evidence suggests that rScO2 is reduced during thoracic surgery involving single lung ventilation, major abdominal surgery, hip surgery, and laparascopic surgery with the patient placed in anti-Tredelenburg’s position. Shoulder arthroscopy in the beach chair and carotid endarterectomy with clamped internal carotid artery also cause pronounced cerebral desaturation. A >20% reduction in rScO2 coincides with indices of regional and global cerebral ischemia during carotid endarterectomy. Following thoracic surgery, major orthopedic and abdominal surgery the occurrence of postoperative cognitive dysfunction might be related to intraoperative cerebral desaturation. In conclusion, certain non-cardiac surgical procedures is associated with an increased risk for the occurrence of regional cerebral oxygenation. Evidence for an association between cerebral desaturation and postoperative outcome parameters other than cognitive dysfunction needs to be established.

    Christopher Riben

    2012-01-01

    Full Text Available Background. Long-term edentulism may in many cases result in resorption of the alveolar process. The sinus lift procedure aims to create increased bone volume in the maxillary sinus in order to enable installation of dental implants in the region. The method is over 30 years old, and initially autogenous bone grafts were used and later also different bone substitutes. Since 1997, a limited number of studies have explored the possibility of a graftless procedure where the void under the sinus membrane is filled with a blood clot that enables bone formation. Aim. To describe the evolution of the sinus-lift technique and to review the literature related to the technique with a focus on long-term studies related to the graft-less technique. Methods. The electronic database PubMed was searched, and a systematic review was conducted regarding relevant articles. Results. A relatively few long-term studies using the described technique were found. However, the technique was described as reliable considering the outcome of the existing studies. Conclusion. All investigated studies show high implant survival rates for the graftless technique. The technique is considered to be cost-effective, less time-consuming, and related to lower morbidity since no bone harvesting is needed.

  19. Perfusionist strategies for blood conservation in pediatric cardiac surgery.

    Durandy, Yves

    2010-02-26

    There is increasing concern about the safety of homologous blood transfusion during cardiac surgery, and a restrictive transfusion practice is associated with improved outcome. Transfusion-free pediatric cardiac surgery is unrealistic for the vast majority of procedures in neonates or small infants; however, considerable progress has been made by using techniques that decrease the need for homologous blood products or even allow bloodless surgery in older infants and children. These techniques involve a decrease in prime volume by downsizing the bypass circuit with the help of vacuum-assisted venous drainage, microplegia, autologous blood predonation with or without infusion of recombinant (erythropoietin), cell salvaging, ultrafiltration and retrograde autologous priming. The three major techniques which are simple, safe, efficient, and cost-effective are: a prime volume as small as possible, cardioplegia with negligible hydric balance and circuit residual blood salvaged without any alteration. Furthermore, these three techniques can be used for all the patients, including emergencies and small babies. In every pediatric surgical unit, a strategy to decrease or avoid blood bank transfusion must be implemented. A strategy to minimize transfusion requirement requires a combined effort involving the entire surgical team with pre-, peri-, and postoperative planning and management. PMID:21160681

    1996-01-01

    OBJECTIVE. A review was performed to investigate the frequency of occurrence and outcome of patients who have retained surgical sponges. METHODS. Closed case records from the files of the Medical Professional Mutual Insurance Company (ProMutual, Boston, MA) involving a claim of retained surgical sponges were reviewed for a 7-year period. RESULTS. Retained sponges occurred in 40 patients, comprising 48% of all closed claims for retained foreign bodies. A falsely correct sponge count after an abdominal procedure was documented in 76% of these claims. Ten percent of claims involved vaginal deliveries and minor non-body cavity procedures, for which no sponge count was performed. Total indemnity payments were $2,072,319, and defense costs were $572,079. In three cases, the surgeon was deemed responsible by the court despite the nursing staff's admitting liability and evidence presented that the surgeon complied completely with the standard of care. A wide range of indemnity payments was made despite a remarkable similarity of outcome in the patients studied. CONCLUSIONS. Despite the rarity of the reporting of a retained surgical sponge, this occurrence appears to be encountered more commonly than generally is appreciated. Operating teams should ensure that sponges be counted for all vaginal and any incisional procedures at risk for retaining a sponge. In addition, the surgeon should not unquestioningly accept correct count reports, but should develop the habit of performing a brief but thorough routine postprocedure wound/body cavity exploration before wound closure. The strikingly similar outcome for most patients would argue for a standardized indemnity payment being made without the need for adversarial legal procedures. PMID:8678622

    Surgical ablation is a recommended procedure for patients with atrial fibrillation (AF) undergoing a cardiac surgery operation. However, the procedure is associated with significant risk of late recurrence of AF. The aim of the study was to assess the long-term efficacy of the procedure with respect to the comorbidities. The study group consisted of 22 patients: 9 women and 13 men, who underwent surgical AF ablation in the 2008-2013 period. The patients were interviewed by telephone and were asked to send their recently performed 12-lead electrocardiography (ECG). The semi-structured interview consisted of 25 items regarding the history of AF, concomitant comorbidities, lifelong syncopal history, smoking, family history of premature cardiovascular diseases, and current medical treatment. Furthermore, the Epworth test was performed to measure the daytime sleepiness, which in turn is related to the presence of obstructive sleep apnoea. On the basis of the obtained data, the CHADS2, and Epworth scale scores were calculated for each patient. As a result of the study six patients (27%) had sinus rhythm or paced dual chamber rhythm, and 16 patients had atrial fibrillation. The multivariate analysis revealed that Epworth scale scoring > 9, CHADS2 score > 0, and persistent type of AF were related to poor outcome of surgical ablation procedure. In conclusion, patients with AF treated with surgical ablation have similar prognosis of sinus rhythm maintenance to those treated with radiofrequency ablation. Moreover, the same predisposing factors play a significant role in AF recurrence both in surgical patients and in patients treated with radiofrequency ablation. PMID:26855645

    International Nuclear Information System (INIS)

    Objective: To review and summarize effectiveness and method of the Boston's balloon dilation in cardiac achalasia. Methods: The intensified guide wire was inserted into stomach through mouth cavity under TV control. The Boston's balloon was inserted to the cardiac stricture through the guide wire and dilatated with 15% contrast medium with to a maximum diameter for five minutes and then the balloon was dilatated again for 3-5 minutes, all together for 3-4 times. The severe stricture must be pre-dilatated with 20-25 mm diameter balloon. Results: The balloon insertion was technically successful in all 26 patients. The once success of balloon dilation was achieved in 24 patients and twice in other 2. Follow-up time was from 2 weeks to 31 months (mean 10.6 months). Recurrent stenosis had not occurred in all patients. Remission rate of dysphagia was 100%. Esophageal reflux occurred in 3 patients. Conclusions: The Boston's balloon dilatation is simple and effective for treatment of cardiac achalasia. The method sometimes may replace surgical procedure

    Surgery remains an acceptable, and sometimes necessary, modality for the treatment of ectopic pregnancy. Laparoscopy is the preferred method of access, yet controversy remains regarding the optimal procedure and postoperative management. Generally, salpingostomy is employed with the goal of maintaining fertility, although data to support this tenet are lacking. In most cases, the decision to perform conservative versus radical surgery is on the basis of the patient's history, her desire for future fertility, and surgical findings. The procedures of salpingostomy and salpingectomy, techniques to prevent and control blood loss at the time of surgery, and surgical options for nontubal ectopic pregnancies are reviewed.

    Full Text Available Introduction: A combined carotid endarterectomy (CEA and cardiac procedure has higher early risk of stroke than isolated CEA because of the widespread atherosclerosis in patients selected for simultaneous procedures. In this retrospective study, we review the results of combined coronary artery bypass grafting (CABG and carotid endarterectomy (CEA procedures. Materials and methods: Between January 2000 and December 2007, 91 patients with a mean age of 69.2+6.6 (24/67 female/male underwent combined operations (CEA-CABG on cardiopulmonary bypass (CPB as elective surgery. The study population was divided, as follows: Group A: 83 patients (91.2% had both venous and arterial revascularization; Group B: 8 patients (8.8% had total arterial revascularization. CEA was performed in case of stenosis more than 80% and always before cardiac operation. These techniques were used: standard procedure (54.8%, eversion (39.2%, patch enlargement (6%. Immediately after the vascular procedure, CABGs were performed through median sternotomy. The mean EUROscore was 6.9+2.5%. Results: All neurological complications were in the group who underwent both venous and arterial revascularization (Group A, where a proximal anastomosis was made. All complications and deaths were in group A. Six patients had stroke (6.6% and 2 had acute myocardial infarction (AMI (2.2%. There were 8 in-hospital deaths (8.8% and 1 late death (for stroke after five months. Conclusions: In our center, the incidence of stroke in simultaneous cardiovascular procedures was 5.5 times greater than in isolated cardiac or vascular procedures, which was probably related to the widespread vessels disease. An aortic cross clamp and surgical procedure on the ascending aorta are relevant risk factors for developing neurological events; much attention should be paid to aortic manipulation. In the sub-group who underwent total arterial revascularization with associated CEA procedures, we had no neurological

    Full Text Available Patients with dissecting aortic aneurysm and associated acute aortic insufficiency form a group of seriously ill patients with significant cardiac failure, generally involving other organs and systems. It justifies an attempt to reduce a surgical risk, by using more sparing procedures, including supracoronary replacement of the ascending aorta with its root reconstruction. The latter has been performed in 27 patients (mean 54,5 ± 2,1 years with dissecting aortic aneurysm and aortic valvular insufficiency in 1996 to 2009. The major etiological factor was atherosclerosis (88%/ Seventeen (63%, 6 (22,2% and 4 (16% had types I, IIA and II dissection, respectively. Overall hospital mortality was 11%. In late period, progressive aneurysm dissection needed reinterventions in 2 cases. The competence of the reconstructed aortic valve was satisfactory both just after surgery and throughout the follow-up. Indications for this option of chronic correction, surgical techniques, and immediate and long-term results are outlined.

    2016-06-01

    There are two main surgical treatments for osteoarthritis: conservative treatments, where the damaged cartilage is left in place, and radical treatments, where the cartilage is replaced by an artificial endoprosthesis; this latter procedure is termed joint arthroplasty. These treatments are only offered to symptomatic patients. Arthrodesis is yet another surgical intervention in cases of osteoarthritis. It will sacrifice the joint's articular function and is performed on small osteoarthritic joints, such as wrists and ankles, for instance. Osteoarthritis symptoms are usually the consequence of an imbalance between the load applied to a joint and the surface available to support that load. Therefore, conservative treatments will either tend to decrease the load exerted on the joint, such as in a tibial valgus osteotomy for instance, or to improve the articular surface supporting that load. Sometimes, both can be provided at the same time; the peri-acetabular osteotomy for hip dysplasia is an example of such a procedure. Conservative treatments are usually offered to young patients in order to delay, if not avoid, the need for a joint prosthesis. They are usually performed before osteoarthritis appears or at an early stage. Joint arthroplasties have overwhelmingly excellent functional results and today's research is directed towards providing rapid recovery, very long-term stability, and the assurance of a good functionality in extreme conditions. However, complications with joint arthroplasties can be serious with little, if any, reasonable salvage solution. Therefore, these procedures are offered to patients who have failed adequate medical treatment measures. PMID:27185463

    Full Text Available End-stage renal disease (ESRD is known to be an important risk factor for cardiac operations performed with cardiopulmonary bypass. We investigated the influence of preoperative status on perioperative mortality and morbidity. We retrospectively analyzed data from 26 patients with ESRD, who were on maintenance dialysis and underwent a cardiac surgical procedure bet-ween 2000 and 2007. Of them, 61.5% of the patients had isolated coronary artery bypass grafting (CABG and 38.5% had replacement or reconstruction of one or two valves. The perioperative mortality rate was 26% with five deaths occurring in patients undergoing CABG procedure. We found CABG procedure, being female and left ventricular (LV function < 30% to be associated with a higher relative risk for perioperative death. In conclusion, our data suggest that both indi-cations and referral for surgical intervention for coronary artery disease may be delayed in pa-tients who have ESRD, contributing to the relatively high perioperative mortality.

    2014-10-01

    Full Text Available Objective: Surgery is among the causes of acute pain. One of the major problems of patients after surgical procedures is postoperative pain. Annually, millions of people throughout the world undergo surgery and experience different intensities of postoperative pain. Due to physiological changes and given the stability of the heart and lung, the management and control of pain is rarely considered as a priority in the care of patients after cardiac surgery. Cardiac surgical patients experience pain due to the surgical incision and between the ribs nerve injury created during the course of the surgery, and irritation and inflammation of the pleura by catheters. Control and management of pain in intensive care units (ICU are the main tasks in nursing care. The purpose of this review study was the investigation, assessment, and management of pain in patients after cardiac surgery. Materials and Methods: In this study, the literature available on Magiran, Google Scholar, ScienceDirect, and PubMed were collected, and after reviewing, the relevant literature was studied. Results: Although pain is one of the major stressors in patients undergoing surgery, the measures taken for the treatment and care of these patients are associated with experiencing pain. In this regard, all the resources have emphasized the using of guidelines and tools to assess patients' pain. However, in cardiac surgery patients, sufficient attention is not paid to pain control. Patients reported poorly controlled pain and experiences of moderate to severe pain after surgery. Conclusion: Pain is a subjective experience, and in patients who cannot report their pain, it should be considered important. According to numerous studies, pain control is not performed in ICUs. Thus, efforts should be made for appropriate control and reduction of pain, use of valid methods to determine and control pain, and improvement of the quality of the programs.

    BACKGROUND:Treatment of chronic pancreatitis (CP) is a challenging condition for surgeons. During the last decades, increasing knowledge about pathophysiology of CP, improved results of major pancreatic resections, and integration of sophisticated diagnostic methods in clinical practice have resulted in signiifcant changes in surgery for CP. DATA SOURCES:To detail the indications for CP surgery, the surgical procedures, and outcome, a Pubmed database search was performed. The abstracts of searched articles about surgical management of CP were reviewed. The articles could be identiifed and further scrutinized. Further references were extracted by cross-referencing. RESULTS: Main indications of CP for surgery are intractable pain, suspicion of malignancy, and involvement of adjacent organs. The goal of surgical treatment is to improve the quality of life of patients. The surgical approach to CP should be individualized according to pancreatic anatomy, pain characteristics, baseline exocrine and endocrine function, and medical co-morbidity. The approach usually involves pancreatic duct drainage and resection including longitudinal pancreatojejunostomy, pancreatoduodenectomy (Whipple's procedure), pylorus-preserving pancreatoduodenectomy, distal pancreatectomy, total pancreatectomy, duodenum-preserving pancreatic head resection (Beger's procedure), and local resection of the pancreatic head with longitudinal pancreatojejunostomy (Frey's procedure). Non-pancreatic and endoscopic management of pain has also been advocated. CONCLUSIONS:Surgical procedures provide long-term pain relief, a good postoperative quality of life with preservation of endocrine and exocrine pancreatic function, and are associated with low early and late mortality and morbidity. In addition to available results from randomized controlled trials, new studies are needed to determine which procedure is the most effective for the management of patients with CP.

    Cachexia is the loss of body weight associated with several chronic diseases including chronic heart failure (CHF). The cachectic condition is mainly due to loss of skeletal muscle mass and adipose tissue depletion. The majority of experimental in vivo studies on cachexia rely on animal models of cancer cachexia while a reliable and appropriate model for cardiac cachexia has not yet been established. A critical issue in generating a cardiac cachexia model is that genetic modifications or pharmacological treatments impairing the heart functionality and used to obtain the heart failure model might likely impair the skeletal muscle, this also being a striated muscle and sharing with the myocardium several molecular and physiological mechanisms. On the other hand, often, the induction of heart damage in the several existing models of heart failure does not necessarily lead to skeletal muscle loss and cachexia. Here we describe the main features of cardiac cachexia and illustrate some animal models proposed for cardiac cachexia studies; they include the genetic calsequestrin and Dahl salt-sensitive models, the monocrotaline model and the surgical models obtained by left anterior descending (LAD) ligation, transverse aortic constriction (TAC) and ascending aortic banding. The availability of a specific animal model for cardiac cachexia is a crucial issue since, besides the common aspects of cachexia in the different syndromes, each disease has some peculiarities in its etiology and pathophysiology leading to cachexia. Such peculiarities need to be unraveled in order to find new targets for effective therapies. PMID:27317993

    Full Text Available The authors report a case of cardiac arrest in a patient receiving intravenous (IV metoclopramide and review the pertinent literature. A 62-year-old morbidly obese female admitted for a gastric sleeve procedure, developed cardiac arrest within one minute of receiving metoclopramide 10 mg via slow intravenous (IV injection. Bradycardia at 4 beats/min immediately appeared, progressing rapidly to asystole. Chest compressions restored vital function. Electrocardiogram (ECG revealed ST depression indicative of myocardial injury. Following intubation, the patient was transferred to the intensive care unit. Various cardiac dysrrhythmias including supraventricular tachycardia (SVT associated with hypertension and atrial fibrillation occurred. Following IV esmolol and metoprolol, the patient reverted to normal sinus rhythm. Repeat ECGs revealed ST depression resolution without pre-admission changes. Metoclopramide is a non-specific dopamine receptor antagonist. Seven cases of cardiac arrest and one of sinus arrest with metoclopramide were found in the literature. The metoclopramide prescribing information does not list precautions or adverse drug reactions (ADRs related to cardiac arrest. The reaction is not dose related but may relate to the IV administration route. Coronary artery disease was the sole risk factor identified. According to Naranjo, the association was possible. Other reports of cardiac arrest, severe bradycardia, and SVT were reviewed. In one case, five separate IV doses of 10 mg metoclopramide were immediately followed by asystole repeatedly. The mechanism(s underlying metoclopramide’s cardiac arrest-inducing effects is unknown. Structural similarities to procainamide may play a role. In view of eight previous cases of cardiac arrest from metoclopramide having been reported, further elucidation of this ADR and patient monitoring is needed. Our report should alert clinicians to monitor patients and remain diligent in surveillance and

    During the neonatal period, cardiac energy metabolism progresses from a fetal glycolytic profile towards one more dependent on mitochondrial oxidative metabolism. In this study, we identified the effects of cardiac hypertrophy on neonatal cardiac metabolic maturation and its impact on neonatal postischemic functional recovery. Seven-day-old rabbits were subjected to either a sham or a surgical procedure to induce a left-to-right shunt via an aortocaval fistula to cause RV volume-overload. At 3 wk of age, hearts were isolated from both groups and perfused as isolated, biventricular preparations to assess cardiac energy metabolism. Volume-overload resulted in cardiac hypertrophy (16% increase in cardiac mass, P < 0.05) without evidence of cardiac dysfunction in vivo or in vitro. Fatty acid oxidation rates were 60% lower (P < 0.05) in hypertrophied hearts than controls, whereas glycolysis increased 246% (P < 0.05). In contrast, glucose and lactate oxidation rates were unchanged. Overall ATP production rates were significantly lower in hypertrophied hearts, resulting in increased AMP-to-ATP ratios in both aerobic hearts and ischemia-reperfused hearts. The lowered energy generation of hypertrophied hearts depressed functional recovery from ischemia. Decreased fatty acid oxidation rates were accompanied by increased malonyl-CoA levels due to decreased malonyl-CoA decarboxylase activity/expression. Increased glycolysis in hypertrophied hearts was accompanied by a significant increase in hypoxia-inducible factor-1α expression, a key transcriptional regulator of glycolysis. Cardiac hypertrophy in the neonatal heart results in a reemergence of the fetal metabolic profile, which compromises ATP production in the rapidly maturing heart and impairs recovery of function following ischemia.

    Introduction. Surgical camps are preplanned activities where volunteer surgical teams congregate at specified place(s) and perform a wide range of mostly elective procedures for a limited period of time. This is usually at no cost to the patients, who belong to vulnerable (poor and hard to reach) communities. We describe a surgical camp model and its challenges as a means of improving access to surgical services. Methods. A cross-sectional descriptive study. Data from a recent Association of Surgeons of Uganda surgical camp were collected and analyzed for demographics, costs, procedure types, and rates and, in addition, challenges encountered and solutions. Personnel that participated in this exercise included specialist surgeons, surgical residents, medical officers, clinical officers, anesthetists, and theater nurses (a total of 121 staff). Results. In total, 551 procedures were performed during a four-day-long camp. Mean age was 35 years (SD 23), M : F ratio was 2 : 1. Herniorrhaphy, skin lump excision, hydrocelectomy, and thyroidectomy formed 81% of all the procedures. Average cost per procedure was $73 USD. Conclusion. Surgical camps offer increased access to surgical services to vulnerable populations. Hernias and goiters were most common. Surgical camps should become an integral part of the Health Service delivery in low-resourced environments. PMID:27413775

    Objective To compare surgical (SgT) and percutaneous (PcT) tracheostomies. Background Percutaneous tracheostomy has been said to provide numerous advantages over classical SgT. Methods A prospective randomized trial with a double-blind evaluation was used to compare SgT and PcT. SgT and PcT were performed according to established techniques (n = 70). The procedure was performed at the bedside in the intensive care unit in 21 cases (30%). The outcome measures were divided into procedure-related variables, perioperative complications, and postoperative complications. The procedure-related variables (location, duration, and difficulty) were evaluated by the surgeon. The perioperative and postoperative complications were divided into serious, intermediate, and minor. Perioperative and early postoperative (14 days) complications were evaluated daily by an intensive care unit nurse blinded to the technique used. Long-term postoperative complications were evaluated 3 months after decannulation by a surgeon blinded to the surgical technique. Results There were no major complications in either group. Most variables studied were not statistically different between the PcT and SgT groups. The only variables to reach statistical significance were the size of the incision (smaller with PcT, p < 0.0001), minor perioperative complications (greater with PcT, p = 0.02), and difficult cannula changes (greater with PcT; p < 0.05). Among nonsignificant differences, difficult procedures and false passages were more frequent with PcT, whereas long-term unesthetic scars were more frequent with SgT. Conclusions Both techniques are associated with a low rate of serious or intermediate complications when performed by experienced surgeons. There were more minor perioperative complications with PcT and more minor long-term complications with SgT. PMID:10561096

    Full Text Available Tetralogy of Fallot (TOF is the first described and most common cyanotic congenital heart anomaly that generated the first successful surgical palliation procedure and definitive intracardiac repair. Classical TOF comprises the four typical features of right ventricular outflow tract obstruction (RVOTO, right ventricular hypertrophy (RVH, ventricular septal defect (VSD and aortic dextroposition. Complex forms of the condition include TOF associated with absent pulmonary valve and TOF with pulmonary atresia (TOF-PA with or without major aortopulmonary collateral arteries (MAPCAs. The pathophysiological understanding that the tetrad is basically the sequel of a singular abnormality of infundibular malformation, with anterior deviation of the infundibular septum, had major surgical consequences that improved survival. Diagnostic and functional imaging play a key role in the clinical and surgical management of patients with TOF. We revisit the role of traditionally employed imaging modalities (echocardiography and cardiac catheterisation only briefly as these remain within the domain of cardiology practice. The emphasis of the present review is to outline the role of cardiac computed tomographic angiography (CTA in the evaluation of TOF, with special reference to the technical considerations and best practice recommendations. Cardiovascular magnetic resonance imaging (CMR is addressed only in passing, as this service is not currently available at our institution.

    A surgical item unintentionally retained in a patient after an operative or other invasive procedure is a serious, preventable medical error with the potential to cause the patient great harm. Perioperative RNs play a key role in preventing retained surgical items (RSIs). The updated AORN "Guideline for prevention of retained surgical items" provides guidance for implementing a consistent, multidisciplinary approach to RSI prevention; accounting for surgical items; preventing retention of device fragments; reconciling count discrepancies; and using adjunct technologies to supplement manual count procedures. This article focuses on key points of the guideline to help perioperative personnel provide optimal care during a procedure. Key points addressed include taking responsibility for RSI prevention as a team; minimizing distractions, noise, and interruptions during counts; using consistent counting methods; reconciling discrepancies; and participating in performance-improvement activities. Perioperative RNs should review the complete guideline for additional information and for guidance in writing and updating policies and procedures. PMID:27350354

    As a result of the trend toward late childbearing, fertility preser- vation has become a major issue in young women with gynaeco- logical cancer. Fertility-sparing treatments have been successfully attempted in selected cases of cervical, endometrial and ovarian cancer, and gynaecologists should be familiar with fertility- preserving options in women with gynaecological malignancies. Options to preserve fertility include shielding to reduce radiation damage, fertility preservation when underg...

  13. [Surgical controversy. Combined surgery in one procedure].

    Combined surgery (phacoemulsification and penetrating or nonpenetrating filtering surgery) has the advantage of treating two distinct disorders in a single operation, with the objective of improving visual acuity and controlling ocular hypertension. In addition, it improves patient comfort and compliance to treatment. It lowers intraocular pressure more than simple lens surgery and the same as surgery carried out in two steps, notably with nonpenetrating filtering surgery, whereas the incidence of complications is lower. Our personal experience with 35 patients, operated on for phacoemulsification and deep sclerectomy with external trabeculectomy in the same operation confirms that this combined surgery in a single operation is effective in controlling ocular pressure in glaucoma subjects (mean reduction in tension, 23%), with few complications.

    Despite the efficacy of cardiac surgery, less invasive interventions with more uncertain long-term outcomes are increasingly challenging surgery as first-line treatment for several congenital, degenerative and ischemic cardiac diseases. The specialty must evolve if it is to ensure its future relevance. More importantly, it must evolve to ensure that future patients have access to treatments with proven long-term effectiveness. This cannot be achieved without dynamic leadership; however, our contention is that this is not enough. The demands of a modern surgical career and the importance of the task at hand are such that the serendipitous emergence of traditional charismatic leadership cannot be relied upon to deliver necessary change. We advocate systematic analysis and strategic leadership at a local, national and international level in four key areas: Clinical Care, Research, Education and Training, and Stakeholder Engagement. While we anticipate that exceptional individuals will continue to shape the future of our specialty, the creation of robust structures to deliver collective leadership in these key areas is of paramount importance.

    Full Text Available There is a spectrum of different types of cardiac"ncalcifications with the importance and significance"nof each type of cardiac calcification, especially"ncoronary artery calcification. Radiologic detection of"ncalcifications within the heart is quite common. The"namount of coronary artery calcification correlates"nwith the severity of coronary artery disease (CAD."nCalcification of the aortic or mitral valve may indicate"nhemodynamically significant valvular stenosis."nMyocardial calcification is a sign of prior infarction,"nwhile pericardial calcification is strongly associated"nwith constrictive pericarditis. A spectrum of different"ntypes of cardiac calcifications (linear, annular,"ncurvilinear,... could be seen in chest radiography and"nother imaging modalities. So a carful inspection for"ndetection and reorganization of these calcifications"nshould be necessary. Numerous modalities exist for"nidentifying coronary calcification, including plain"nradiography, fluoroscopy, intravascular ultrasound,"nMRI, echocardiography, and conventional, helical and"nelectron-beam CT (EBCT. Coronary calcifications"ndetected on EBCT or helical CT can be quantifie,"nand a total calcification score (Cardiac Calcification"nScoring may be calculated. In an asymptomatic"npopulation and/or patients with concomitant risk"nfactors like diabetes mellitus, determination of the"npresence of coronary calcifications identifies the"npatients at risk for future myocardial infarction and"ncoronary artery disease. In patients without coronary"ncalcifications, future cardiovascular events could"nbe excluded. Therefore, detecting and recognizing"ncalcification related to the heart on chest radiography"nand other imaging modalities such as fluoroscopy, CT"nand echocardiography may have important clinical"nimplications.

    The purpose of this study was to evaluate the dose received by health professionals in the hemodynamic sector of a university hospital in Sao Paulo city. A self-applied questionnaire was used to delineate the profile of health professionals, taking into account sociodemographic variables and variables related to the work with ionizing radiation. The assessment of occupational doses was performed by consulting of the individual dose records of the institution database from 2000 to 2009. A total of 240 records was evaluated, corresponding to 38 active professionals (2009), divided in different professional category: physician, nurses, radiologic technologists and nursing assistants. The annual doses were compared with the limits established by national regulatory authorities. Based on the effective doses received and recorded during the studied period, experimental measures were performed with TL dosimeters in five physicians to evaluate the equivalent dose, in the left hand, during hemodynamic procedures. In addition, the radioprotection measures adopted by health professionals were verified. This study allowed delineating the profile of medical staff that integrates the hemodynamic service as well as knowing the distribution of their doses in relation to limits over the years. (author)

  17. Radiography in cardiology [cardiac disorders, cardiac insufficiency

    International Nuclear Information System (INIS)

    The diagnostic procedure in cardiology nearly always requires an X-ray examination of the thorax. This examination is very informative when it is correctly performed and interpreted. The radiographs need to be read precisely and comprehensively: this includes the evaluation of the silhouette of the heart (size, form and position) as well as the examination of extra-cardiac thoracic structures allowing among other things to search for signs of cardiac insufficiency. The conclusion of the X-ray examination can be drawn after having brought together information concerning the case history, the clinical examination and the study of the radiographs. The radiologist finds himself in one of three situations: (1) the information provided by the X-ray pictures is characteristic of a disease and permits a diagnosis, (2) the X-ray pictures indicate a group of hypotheses; further complementary tests could be useful and (3) the X-ray pictures provide ambiguous even contradictory information; it is necessary to complete the radiological examination by other techniques such as an ultrasonographic study of the heart

    Surgical training is changing: one hundred years of tradition is being challenged by legal and ethical concerns for patient safety, work hours restrictions, the cost of operating room time, and complications. Surgical simulation and skills training offers an opportunity to teach and practice advanced skills outside of the operating room environment before attempting them on living patients.Simulation training can be as straight forward as using real instruments and video equipment to manipulate simulated "tissue" in a box trainer. More advanced,virtual reality simulators are now available and ready for widespread use. Early systems have demonstrated their effectiveness and discriminative ability. Newer systems enable the development of comprehensive curricula and full procedural simulations.The Accreditation Council of Graduate Medical Education's (ACGME) has mandated the development of novel methods of training and evaluation. Surgical organizations are calling for methods to ensure the maintenance of skills, advance surgical training, and to credential surgeons as technically competent.Simulators in their current form have been demonstrated to improve the operating room performance of surgical residents. Development of standardized training curricula remains an urgent and important agenda, particularly for minimal invasive surgery.An innovative and progressive approach, borrowing experiences from the field of aviation, can provide the foundation for the next century of surgical training,ensuring the quality of the product. As the technology develops, the way we practice will continue to evolve, to the benefit of physicians and patients.
