Filter by:Worldwide, the rising incidence of obesity has led to the identification of an obesity related syndrome, called metabolic. This syndrome is characterized by central obesity, hypertension, insulin resistance and altered lipid levels. Taking into consideration the rising incidence of obesity, anesthetists will more frequently encounter patients with metabolic syndrome, in their everyday practice. Moreover, the comorbidities that are related to the metabolic syndrome, increase the risk for perioperative complications. Therefore, strategies that will evaluate and modify the risk will be of great importance in the management of these patients, in order to maximize peri-anaesthetic and surgical safety. The aim of the study is to assess the incidence of metabolic syndrome and the impact of its presence on the outcome of patients undergoing elective laparotomy.
The aim of this study was to compare the efficacy of a diode laser (DL) as an adjunct to conventional scaling in the treatment of mild-to-moderate peri-implantitis. A prospective clinical, radiographic and microbiologic split-mouth study was conducted to test the following null hypothesis; adjunct application of a diode laser, in the conventional treatment of peri-implantitis, are not associated with a statistically significant difference regarding the microbial counts, marginal bone loss and peri-implant parameters.
An email questionnaire about subjective satisfaction and discomfort has been sent to 243 patients undergoing non-surgical facial and cervical lift 1 week, 1 month, 6 months and 1 year after treatment.
This study is designed to test if measuring the depth of anaesthesia, brain tissue oxygenation and haemodynamic parameters and specially designed interventions according to the measurements can improve the outcome of high risk surgical patients undergoing major abdominal surgery.
The goal of this clinical research study is to learn more about the safety and feasibility of using the Da Vinci Robotic Surgical system in procedures that harvest the latissimus dorsi muscle (a back muscle below your shoulder) for reconstructive procedures.
Colorectal cancer is a major cause of morbidity and mortality in Western countries. Scientific studies have shown that endoscopic polypectomy is efficacious in preventing CRC incidence and mortality. Endoscopic polypectomy carries a risk of major complications, such as bleeding or bowel perforation, so that a careful balance between efficacy and safety appears to be clinically relevant. Most of the polypectomies are performed for diminutive (<5 mm) or small (6-9 mm) lesions, which represent over 90% of all the polyps. To minimize the risk of complications when removing <10 mm polyps, cold-polypectomy techniques - i.e. without electric current - by means of biopsy forceps or snare, have been proposed. Although the risk of perforation is virtually excluded by cold-polypectomy, the lack of electrocautery may result in an increased risk of bleeding. The safety of cold-snare polypectomy has however been recently shown in controlled trials. Regarding the efficacy of cold-polypectomy for subcentimetric polyps, very few studies have assessed the post-polypectomy completeness of the removal of polyp tissue (i.e. residual disease), and no studies have compared it to conventional polypectomy. The investigators perform this study to assess both the efficacy and safety of a novel snare (Exacto™) for polyp removal.
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 sevoflurane and desflurane for the prevention of catheter-related bladder discomfort.
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.
