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 …

Role of intraoperative ultrasound in the screening of liver metastases from colorectal carcinoma: initial experiences.

1989

The aim of this study was to assess the utility of intraoperative ultrasound (IOUS) in the diagnosis and management of liver metastases from colorectal carcinoma. IOUS was performed on a consecutive series of 70 patients undergoing surgery for colorectal carcinoma, with follow-up ranging from 6 to 24 months. In ten cases (14.3%), 13 metastatic tumours were diagnosed; only six of these had been found by preoperative workup and/or surgical inspection. Seven (53.9%) small metastatic liver lesions were identified only by IOUS. None of the lesions diagnosed by IOUS was palpable, and they were all extremely small--ranging from 4 x 6 to 12 x 16 mm. Seventy-three locations were examined in order to…

Intraoperative identification and neurophysiologic parameters to verify pelvic autonomic nerve function during total mesorectal excision for rectal c…

2003

Abstract Background Preservation of parasympathetic and sympathetic nerves is required to avoid urogenital function disturbances after total mesorectal excision (TME) for rectal carcinoma. This study sought to determine whether intraoperative stimulation of parasympathetic nerves with monitoring of bladder contraction is useful in meeting this demand. Study design In a prospective pilot study, 17 patients, 11 men and 6 women, underwent TME with pelvic autonomic nerve preservation performed by an experienced surgeon. The parasympathetic nerves were stimulated by an electrostimulation device (Screener 3625, Medronic), and the resulting bladder contraction was measured manometrically in all pa…

Intraoperative ultrasound-assisted approach for endoscopic treatment of vesicoureteral reflux in children

2017

Purpose Despite minimal invasiveness and high success rate, guidelines still prescribe voiding Cystourethrogram (VCUG) after endoscopic treatment for vesicoureteral reflux (VUR) in children. The aim of this paper was to analyze whether intraoperative ultrasound (IO-US) could improve surgical accuracy and perioperative counseling, thus potentially decreasing the need for postoperative VCUG. Methods We selected children treated for moderate to high grade VUR, renal scarring or repeated infections under antibiotic prophylaxis from January to December 2015. Endoscopic injection was combined with IO-US to detect optimal needle placement and to guide mound formation. IO-US findings were compared …

Intraoperative tramadol reduces shivering but not pain after remifentanil–isoflurane general anaesthesia. A placebo-controlled, double-blind trial

2008

Background and objective Postoperative shivering and pain are frequent problems in patients recovering from anaesthesia with particularly high incidences being observed after remifentanil–isoflurane-based general anaesthesia. The opioid tramadol is generally effective in preventing shivering and treating pain, but its effects are not characterized after remifentanil-based general anaesthesia. This randomized, placebo-controlled, double-blind study evaluated the effects of intraoperative intravenous tramadol on postoperative shivering and pain after remifentanil-based general anaesthesia. Methods After Ethics Committee approval, 60 patients scheduled for lumbar disc surgery were included. Su…

Perioperative and Periprocedural Management of Antithrombotic Therapy: Consensus Document of SEC, SEDAR, SEACV, SECTCV, AEC, SECPRE, SEPD, SEGO, SEHH…

2018

During the last few years, the number of patients receiving anticoagulant and antiplatelet therapy has increased worldwide. Since this is a chronic treatment, patients receiving it can be expected to need some kind of surgery or intervention during their lifetime that may require treatment discontinuation. The decision to withdraw antithrombotic therapy depends on the patient's thrombotic risk versus hemorrhagic risk. Assessment of both factors will show the precise management of anticoagulant and antiplatelet therapy in these scenarios. The aim of this consensus document, coordinated by the Cardiovascular Thrombosis Working Group of the Spanish Society of Cardiology, and endorsed by most o…

Protective Mechanical Ventilation during General Anesthesia for Open Abdominal Surgery Improves Postoperative Pulmonary Function

2013

Abstract Background: The impact of intraoperative ventilation on postoperative pulmonary complications is not defined. The authors aimed at determining the effectiveness of protective mechanical ventilation during open abdominal surgery on a modified Clinical Pulmonary Infection Score as primary outcome and postoperative pulmonary function. Methods: Prospective randomized, open-label, clinical trial performed in 56 patients scheduled to undergo elective open abdominal surgery lasting more than 2 h. Patients were assigned by envelopes to mechanical ventilation with tidal volume of 9 ml/kg ideal body weight and zero-positive end-expiratory pressure (standard ventilation strategy) or tidal vol…

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…
