OBJECT Whether routine intraoperative angiography is necessary for cerebral aneurysm surgery is currently under debate. In this study the authors prospectively assessed the cerebrovascular surgeon's accuracy in predicting the need for intraoperative angiography. METHODS Between January 2002 and January 2003, 200 consecutive patients (141 female and 59 male patients, mean age 52.8 years) with ...

BACKGROUND Intraoperative awareness (IA) is diagnosed when patients can recall their surroundings or an event related to the surgery that occurred while they were under general anaesthesia. The female gender and Caesarean section are considered to be contributing factors. The aim of the present study was to analyse the frequency of IA in patients undergoing general anaesthesia either for Caesar...

Novel surgical applications include radioguided procedures in parathyroidectomy operations. In order to investigate the feasibility of usage of the portable gamma camera in parathyroidectomy operations; intraoperative radioguided parathyroidectomy operation was performed in three hyperparathyroidism patients with inconclusive preoperative parathyroid scintigraphy results. Intraoperative portabl...

background : subthalamic nucleus (stn) stimulation is the  reatment of choice for carefully chosen patients with idiopathic parkinson's disease (pd) and refractory motor fluctuations. we evaluated the value of intraoperative electrophysiology during stn deep brain stimulation (dbs) procedures in refining the anatomically-defined target. methods : we determined the spatial distance between the a...

OBJECTIVE To determine the beneficial effects of intraoperative high-field magnetic resonance imaging (MRI), multimodal neuronavigation, and intraoperative electrophysiological monitoring-guided surgery for treating supratentorial cavernomas. METHODS Twelve patients with 13 supratentorial cavernomas were prospectively enrolled and operated while using a 1.5 T intraoperative MRI, multimodal ne...

OBJECTIVE To describe which obstetric patients lose enough blood during postpartum hemorrhage to receive a reinfusion of intraoperative blood salvage. METHODS Eight years of intraoperative blood salvage data from a regional tertiary care maternity hospital were analyzed. The volume of blood returned through intraoperative blood salvage was standardized to the volume of red blood cells in an a...

background one of the major problems in surgery is intraoperative bleeding which reduces visibility in the operative field. an important task for an anesthetist during head and neck surgery is to improve intraoperative visibility. objectives the purpose of this study was to compare the amount of bleeding using different doses of oral metoprolol during three common types of nasal operation; rhin...

conclusions premedication with clonidine to decrease intraoperative blood loss can be more effective in patients with opium addiction than the ones without addiction. results intraoperative blood loss in clonidine recipient groups, patients with and without addiction, was less than that of the placebos (both p values < 0.01) and the difference magnitude was higher in patients with opium addicti...
