BACKGROUND We observed an increased rate of pulmonary complications (hypoxemia, pulmonary edema, re-intubation) in some patients after posterior spinal fusion, though standardized intraoperative volume regimens for major surgery were used. Therefore, we focused on the effects of two different standardized fluid regimens (liberal vs. conventional) as well as on two different types of postoperati...

Safe and complete resection represents the first step in the treatment of glioblastomas and is mandatory in increasing the effectiveness of adjuvant therapy to prolong overall survival. With gross total resection currently limited in extent to MRI contrast enhancing areas, the extent to which supra-complete resection beyond obvious contrast enhancement could have impact on overall survival rema...

Background: Laparoscopic splenectomy is evolving procedure and is now considered the procedure of choice in elective splenectomy by many centers, but technically demanding especially in large sized ones. Our aim was to evaluate the outcome of laparoscopic splenectomy for a variety of benign splenic disorders in our early experience. Patients and Methods: This prospective study was carried out o...

BACKGROUND The effectiveness of intraoperative povidone-iodine (PVI) application in the reduction of surgical-site infection (SSI) remains controversial. This meta-analysis was performed to assess the effect of intraoperative PVI application compared with no antiseptic solution (saline or nothing) on the SSI rate. METHODS The meta-analysis included randomized controlled trials that compared i...

OBJECTIVE To compare 20-gauge standard pars plana vitrectomy (PPV) with transconjunctival cannulated PPV in the development of intraoperative retinal breaks and postoperative rhegmatogenous retinal detachments (RRDs) in a large series of patients undergoing PPV for macular pucker or macular hole. METHODS This study was conducted at an academic tertiary care vitreoretinal practice in Milwaukee...

INTRODUCTION Dexmedetomidine (Dex) has sedative, analgesic, and anesthetic-sparing effects. This meta-analysis examines demonstrated intraoperative and postoperative effects of intraoperative Dex administration during pediatric surgery. METHODS A search for randomized placebo-controlled trials was conducted to identify clinical trials examining intraoperative Dex use in children, infants, and...

BACKGROUND Intraoperative sentinel node (SN) identification in patients with head-and-neck malignancies can be challenging due to unexpected drainage patterns and anatomical complexity. Here, intraoperative navigation-based guidance technologies may provide outcome. In this study, gamma camera-based freehandSPECT was evaluated in combination with the hybrid tracer ICG-99mTc-nanocolloid. MATER...

OBJECTIVE We have investigated alternative ways to integrate intraoperative 3D ultrasound images and preoperative MR images in the same 3D scene for visualizing brain shift and improving overview and interpretation in ultrasound-based neuronavigation. MATERIALS AND METHODS A Multi-Modal Volume Visualizer (MMVV) was developed that can read data exported from the SonoWand neuronavigation system...

BACKGROUND Intraoperative hypothermia is linked to postoperative adverse events. The use of warmed, humidified CO2 to establish pneumoperitoneum during laparoscopy has been associated with reduced incidence of intraoperative hypothermia. However, the small number and variable quality of published studies have caused uncertainty about the potential benefit of this therapy. This meta-analysis was...

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 ...
