Toric intraocular lens versus opposite clear corneal incisions to correct astigmatism in eyes having cataract surgery.

2009

To compare toric intraocular lens (IOL) implantation with paired opposite clear corneal incisions (OCCIs) for astigmatism correction in patients having cataract surgery.Ophthalmology Service, Donostia Hospital, San Sebastián, Spain.This randomized prospective clinical study comprised eyes with more than 1.00 diopter (D) of preexisting corneal astigmatism. One group had AcrySof toric IOL implantation and the other, paired 2.75 mm/3.20 mm OCCIs in the steep axis with spherical IOL implantation. Uncorrected (UCVA) and best corrected (BCVA) visual acuity, refraction, corneal and total higher-order aberrations (HOAs), photopic and mesopic contrast sensitivity, and toric IOL axis were measured 3 …

Effect of a closed foldable equator ring on capsular bag shrinkage in cataract surgery.

2005

To evaluate the effect of a closed foldable equator ring (CFER) versus a conventional capsular tension ring (CTR) on capsular bag shrinkage.Department of Ophthalmology, Johannes Gutenberg-University, Mainz, Germany.In this prospective study, 70 eyes of 70 patients were randomized to 2 groups using a 1:1 block scheme. After uneventful cataract surgery, a capsular measuring ring was implanted in all eyes to measure the capsular bag diameter in vivo. In Group 1, a CTR was implanted in the capsular bag. In Group 2, a CFER was inserted. Biometric characteristics such as axial length and the horizontal and vertical corneal radii were measured preoperatively. The capsular bag diameter and capsulor…

Histamine release in mesenteric traction syndrome during abdominal aortic aneurysm surgery: prophylaxis with H1 and H2 antihistamines

2002

Objective and design: Mesenteric traction syndrome is described as sudden tachycardia, hypotension and flush. Among other etiological factors eventeration or mesenteric traction of the small intestine may cause histamine release from mesenteric mast cells. We hypothesized that mesenteric traction syndrome may be positively influenced by prophylactic antihistamine administration.¶Methods: Male patients (n = 17, ASA groups III-IV, 48–78 years old) were investigated in a randomised double blind study during elective abdominal aortic aneurysm (AAA) repair. Eight patients had pre-anaesthetic prophylaxis with dimetindene (H1-receptor antagonist) plus cimetidine (H2-receptor antagonist), 9 patient…

Anesthesia protocols in laboratory animals used for scientific purposes

2018

Background: A suitable, effective and free of complications anesthetic protocol is very important in experimental studies on animal models since it could bias the outcome of a trial. To date there is no universally accepted protocol for induction, maintenance and recovery from anesthesia. The endotracheal intubation with the use of inhalation anesthesia is used very especially in the from of large size laboratory animals, because it is a secure and easy control mode. However, it is not common for small laboratory animals because of the high technical skills required. Aim: The aim of this paper is a review of the main methods of induction of anesthesia in laboratory animals. Materials and me…

Avoiding tunnel collisions between fibular collateral ligament and ACL posterolateral bundle reconstruction

2010

PURPOSE: The purpose of this study was to evaluate the risk of tunnel collisions of the fibular collateral ligament (FCL) and posterolateral bundle anterior cruciate ligament (PLB-ACL) tunnels during a combined FCL and double-dundle (DB) ACL reconstruction. METHODS: Thirty-six 4th-generation synthetic femurs (Sawbones, Pacific Research Laboratories, Vashon, WA) were utilized, and two different femur sizes were used. A FCL tunnel and a PLB-ACL tunnel were reamed on each femur. The tunnels of synthetic specimens that did not have a collision were filled with an epoxy resin augmented with BaSO(4) and radiographic evaluation, and Multidetector CT exams of the specimens were performed. RESULTS: …

Impact of Minimally Invasive Surgery in the Spectrum of Current Achalasia Treatment Options

2011

Minimally invasive Heller myotomy has evolved the “gold standard” procedure for achalasia in the spectrum of current treatment options. The laparoscopic technique has proved superior to the thoracoscopic approach due to improved visualization of the esophagogastric junction. Operative controversies most recently include the length of the myotomy, especially of its fundic part, with respect to the balance between postoperative persistent dysphagia and development of gastroesophageal reflux, as well as the type of the added antireflux procedure. Perioperative mortality should approach 0%, and favorable long-term results can be achieved in > 90%.

Protective ventilation with high versus low positive end-expiratory pressure during one-lung ventilation for thoracic surgery (PROTHOR): study protoc…

2018

Postoperative pulmonary complications (PPC) may result in longer duration of in-hospital stay and even mortality. Both thoracic surgery and intraoperative mechanical ventilation settings add considerably to the risk of PPC. It is unclear if one-lung ventilation (OLV) for thoracic surgery with a strategy of intraoperative high positive end-expiratory pressure (PEEP) and recruitment maneuvers (RM) reduces PPC, compared to low PEEP without RM.PROTHOR is an international, multicenter, randomized, controlled, assessor-blinded, two-arm trial initiated by investigators of the PROtective VEntilation NETwork. In total, 2378 patients will be randomly assigned to one of two different intraoperative me…

Management and Outcome of Mucosal Injury During Pyloromyotomy--An Analytical Survey Study.

2015

Different approaches of dealing with mucosal injury during pyloromyotomy for hypertrophic pyloric stenosis have been described. There is, however, no consensus on the best technique to use. We conducted a survey among International Pediatric Endosurgery Group (IPEG) members on their experience of mucosal injuries during pyloromyotomy, the way in which these were handled, any modification in subsequent postoperative care, and impact on outcome.A confidential survey was sent to IPEG members querying demographic data, number of pyloromyotomies performed, operative approach, incidence of mucosal injury, intraoperative management, and postoperative consequences. Statistical analysis was performe…
