Filter by:Perioperative airway management is a top priority of anesthesiologists in daily work, and endotracheal intubation (ETI) is considered as the gold standard for providing safe glottic seal,effective ventilation and oxygen supplement during general anesthesia. But ETI related complications such as concomitant hemodynamic responses, damage to the oropharyngeal structures at insertion and postoperative sore throat. Laryngeal mask airway(LMA) for the anesthesia management brings new choice with invasive, lighter cardiovascular reaction and many other advantages, particularly suited to short and minimally invasive surgery. But LMA increased the risk of gastrointestinal reflux aspiration than using ETI and it may resulted in intolerance in high airway pressure, especially in elderly patients with increased lung compliance or reduced airway resistance. Furthermore, LMA could not entirely prevent the occurrence of postoperative sore throat and hoarse. To sum up, it is necessary to carry out a multicenter clinical trial to clarify the safety of LMA in elderly patients. The investigators protocol will focus on the incidence of postoperative pulmonary complications (PPCs) when applications of LMA and ETI in elderly patients.
We want to evaluate the efficacy of the glycopyrrolate and atropine for the prevention of catheter-related bladder discomfort.
The aim of this single-center randomized controlled trial is to assess clinical usefulness of positron emission tomography combined with computed tomography (PET CT) in the diagnostic process of suspected cardiovascular implantable electronic device (CIED) infection (lead dependent infective endocarditis, generator pocket infection, fever of unknown origin).
Pain after amputation is a significant problem among amputees. Phantom limb pain may appear in up to 85% of patients and is usually resistant to a wide variety of treatments.It is believed that regional anesthesia, by preventing the establishment of central sensitization, may play a role in reducing the incidence of acute and chronic pain. Therefore the investigators will compare two methods of postoperative analgesic after after amputation by their efficiency and complication.
We want to evaluate the efficacy of the sevoflurane and desflurane for the prevention of catheter-related bladder discomfort.
Postoperative pain after total knee arthroplasty (TKA) can be difficult to manage and may delay recovery. There are multimodal postoperative pain management after TKA, including intravenous opioids, epidural analgesia, peripheral nerve blocks or periarticular infiltration with local anesthetics. All of these treatments may lead to side effects such as nausea, headache, hypotension, urinary retention, partial motor block and infection of the knee. Therefore the investigators will compare three methods of postoperative analgesic after TKA by their efficiency and complication.
The primary purpose of the study was to compare the macular hole closure and visual acuity gain following vitrectomy using SF6 gas tamponade with 7 days of face-down positioning versus C3F8 gas tamponade with 14 days of face-down positioning. The secondary purpose was to report, in each group, the cumulative incidence of cataract development 1 year following macular hole surgery and the proportion of complications (*). ((*) hypertony, hypotony, retinal tear, retinal detachment and endophthalmitis) This prospective randomized study examined a 3 year period. The first patient was included in January 2010 and the last in November 2011. The 12-month follow-up spread out from March 2011 to December 2012. The first group included 31 patients who had undergone macular hole surgery using SF6 gas and who were advised to stay in face-down position for 7 days postoperatively (SF6 group). These patients were compared to 28 patients who had undergone macular hole surgery with C3F8 gas and who were advised to maintain a face-down position for 14 days. Patients in both groups underwent vitrectomy, internal limiting membrane peeling, and fluid-gas exchange using either SF6 or C3F8. Preoperative data included the characterization of the hole with Optical Coherence Tomography (OCT), the best correct visual acuity (VA) recorded in number of letters using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart, classification of the cataract according to the LOCS III and the intraocular pressure IOP. Postoperative data included OCT confirmation of the closure at 6 weeks and 1 year, 1 year's best corrected VA recorded in number of letters (EDTRS chart) and determination of cataract development and extraction as needed.
- It is a prospective,observational, cohort study - The main purpose of the study is to assess the prevalence of diabetic chronic complications in newly diagnosed type 2 diabetics in suburban area of Algiers. - The secondary purpose is to study the impact of diabetic renal complications as a risk factor on the atherothrombotic events.
Background: Reducing postoperative complications remains a dominant challenge for all clinicians. By minimizing the incidence of adverse outcomes, health care costs and patient recovery can be improved. A number of studies have documented that fewer postoperative adverse events occur with the preoperative use of glucocorticoids (GC). Two small manuscripts support the use of GC with particular reference to liver resection. Major hepatectomy can be associated with numerous adverse outcomes (hemorrhage, bile leak, liver failure, wound infection other infectious complications). This rate approaches 54% in some trials. Additionally, the liver is responsible for numerous metabolic functions and actively participates in the acute phase response via the generation of inflammatory mediators and cytokines. Glucocorticoids play an important role in suppressing the over-synthesis of pro-inflammatory cytokines and therefore may assist in reducing postoperative complications. These pro-inflammatory cytokines recruit leukocytes at the site of injury, leading to hepatic parenchymal cell damage. Decreasing pro-inflammatory cytokine ratio may therefore reduce hepatic damage. Methods: The investigators will complete a randomized controlled trial evaluating the incidence of postoperative complications and overall hospital length of stay in adult patients following preoperative vs. no administration of 500 mg of methylprednisolone (MP) within 30 minutes of starting a hepatectomy. This trial will employ block randomization and intention to treat protocols. Four HPB surgeons at University of Calgary will participate in the trial with a planned inclusion of all patients scheduled to undergo hepatectomy in a period of 2 years. Analysis: Standard statistical analysis will include normally or near-normally distributed variables reported as means and non-normally distributed variables as medians. Means will be compared using the student's t test and medians using the Mann-Whitney U test. Differences in proportions among categorical data will be assessed using Fischer's exact test. A p value < 0.05 will represent statistical significance for all comparisons. Hypothesis: Preoperative GC administration will decrease the incidence of postoperative complications and overall hospital length of stay following hepatectomy. Potential Impact: Health care utilization and economics are an expanding area of importance. Reducing post-hepatectomy complications are crucial to this end.
The study compares the therapies of instant multivessel balloon angioplasty plus stent implantation or the balloon angioplasty plus stent implantation of the infarct artery alone with any possible graduated later treatment of the other vessels in patients with acute myocardial infarction with cardioganic shock. The main study hypothesis is to explore if culprit vessel only PCI with potentially subsequent staged revascularization in comparison to immediate multivessel revascularization by PCI in patients with cardiogenic shock complicating acute myocardial infarction reduces the incidence of 30- day mortality and/or severe renal failure requiring renal replacement therapy.
