BACKGROUND Recurrent laryngeal nerve (RLN) injury is a known complication of thyroid/parathyroid surgery. Intraoperative nerve monitoring (IONM) has been used to gain more information regarding the functional status of the RLN intraoperatively; however, the electromyography (EMG) parameters of RLN after nontransection neuropraxic compressive injury remain unknown. METHODS We developed a canin...

PURPOSE The purpose of this study was to compare intraoperative parameters between femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification using Centurion® Vision System with Active Fluidics. SETTING This study was performed at Brasília Ophthalmologic Hospital, Brasília, Federal District, Brazil. PATIENTS AND METHODS This was a prospective randomized compara...

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 ...

Aims: We aimed to compare the effects of anesthesia induction on hemodynamic parameters ketamine-midazolam or etomidate-midazolam combinations and coronary artery bypass grafting surgery.
 Material Methods: 40 adult patients undergoing CABG were randomly allocated into two groups for this prospective randomized double-blinded study. Ketamine group (n = 20) Etomidate 20). Intraoperative pos...

Objective: There are many studies on kidney transplant anesthesia, there is not enough data in the literature terms of intraoperative parameters according to donor type. In this study, we aimed compare hemodynamic adult patients who underwent living-donor and deceased-donor transplantation (KT). Material Methods: The KT were divided into 2 groups Recipients deceased included study as Group 1. A...

OBJECTIVE The study aims to demonstrate the impact of some preoperative clinical parameters on the functional outcome of patients sustaining brachial plexus injuries, and to trace some commentaries about the use of intraoperative monitoring techniques. METHOD A retrospective study one hundred cases of brachial plexus surgery. The analysis regarding postoperative outcomes was performed by comp...

— Various model parameter calculation equations of RF CMOS inductors are compared. The calculation equations are using as variables either Y, Z-parameters or S-parameters. Results are based on on-wafer RF S-parameter measurements of a 3.75 turn spiral inductor fabricated in AMIS 0.7 μm CMOS DM1P n-well technology. Results obtained with calculation equations for a differentially driven inductor ...

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...

Objectives- Recording intraoperative cardiorespiratory events in thoracoscopic total pericardiectomy via transdiaphragmatic camera port in dog to evaluate feasibility and risks of mechanical stimulation of pherenic nerve during this surgical approach.Design- Technical assessment, experimental study.Animals- Nine healthy, male mixed breed dogs.Procedures- Under one lung ventilation inhalation ge...
