A cost-benefit analysis of the ENIGMA trial.

Background: The ENIGMA trial was a prospective, randomized, multicenter study that evaluated the clinical consequences of including N₂O in general anesthesia. Patients who were given a N₂O-free anesthetic when undergoing major surgery for which the expected hospital stay was at least 3 days had lower rates of some postoperative complications. This suggests that, despite a higher consumption of potent inhalational agent, there could be a financial benefit when N₂O is avoided in such settings.

Critical incident monitoring in a teaching hospital--the third report 2003-2008.

Unlabelled: Several factors have been incriminated in the etiologies of critical incidents: shortages in organizing rules, anesthesia technique, patient environment, human factor, team work and communication. This is the third follow up report describing our performance during the last five years (2003-2008). The possible incriminating causes were identified with the objective of avoiding such eventualities and consequently providing a better patient outcome.

Anesthesia for thoracoscopic thymectomy: modified non-muscle relaxant technique--case reports.

Anesthesia for thymectomy in myasthenia gravis is challenging. The anesthetic experience of that technique is quite large. In involves either muscle relaxant or non-muscle relaxant techniques.

Hemodynamic profile during laparoscopic cholecystectomy versus laparoscopic bariatric surgery: the impact of morbid obesity.

The present study investigated the hemodynamic profile using impedance cardiography (ICG) monitor during pneumoperitoneum for laparoscopic cholecystectomy versus bariatric surgery in order to determine the impact of body weight on hemodynamics. METHODS. 32 adult patients (two groups, each 16 patients) were studied.

Hemodynamic profile during laparoscopic cholecystectomy versus laparoscopic bariatric surgery--the impact of morbid obesity.

Unlabelled: The present study investigated the hemodynamic profile using impedance cardiography (ICG) monitor during pneumoperitoneum for laparoscopic cholecystectomy versus bariatric surgery in order to determine the impact of body weight on hemodynamics.

Methods: 32 adult patients (two groups, each 16 patients) were studied. Group 1 (16 patients) scheduled to undergo laparoscopic cholecystectomy (lapchole) with body mass index (BMI) 28 +/- 5kg/m2.

Anesthetic implications for video assisted thoracoscopic thymectomy in myasthenia gravis.

Thymectomy is an established therapy in the management of generalized myasthenia gravis (MG). However, the optimal surgical approach to thymectomy has remained controversial. There are advocates for transternal, transcervical approaches for "maximal" thymectomy.

Perioperative bioelectrical impedence analysis in neurosurgery.

The use of bioelectrical impedence (BI) measurement to assess body composition has recently attracted the attention of anesthesiologists. Analysis of BI provides a non-invasive method to quantify fluid distribution in different body compartments. This study was designed to assess whether BI analysis reflects fluid depletion in neurosurgical patients with moderate blood loss.

Impedance cardiography: noninvasive measurement of hemodynamics and thoracic fluid content during endoscopic thoracic sympathectomy.

Endoscopic thoracic sympathectomy (ETS) is a minimally invasive procedure for treating palmar hyperhidrosis (PH). Hemodynamic changes are associated with CO(2) insufflation during ETS. In the present study, we examined hemodynamic changes during general anesthesia using impedance cardiography (ICG) monitor.

Critical incident reports in adults: an analytical study in a teaching hospital.

Unlabelled: Self-auditing is important to improve the standard of care. In a previous study (1991--1997), we reported human error and equipment factor as the two major causes leading to critical incidents. This study analyzes the computerized database and the medical records of 71 critical incidents reported in the Department morbidity and mortality meeting between 1998--2002, in an attempt to identify factors that have led to critical incidents and compare them with our previous report.

Carotid endarterectomy: a study of cerebral oxygen saturation vs stump pressure.

Background And Aims: Carotid endarterectomy (CEA) is an established surgical procedure for treatment of internal carotid artery (ICA) stenosis. To determine whether or not a carotid shunt is necessary to place, some surgeons measure the stump pressure. We conducted the current study in order to identify whether or not cerebral oxygen saturation (rS02%) can serve as another quantitative measurement to determine the need of carotid shunt during CEA.

The effects of pneumoperitoneum on respiratory mechanics during general anesthesia for bariatric surgery.

Background: The effects of pneumoperitoneum (PPM) on respiratory mechanics during bariatric surgery were investigated.

Patients And Methods: 10 patients with BMI 50.5+/-8 kg/m(2) (range 40.

Variations in dynamic lung compliance during endoscopic thoracic sympathectomy with CO2 insufflation.

Endoscopic thoracic sympathectomy (ETS) is the preferred surgery for treatment of intractable palmar hyperhidrosis (PH). General anesthesia with onelung collapsed ventilation (OLCV) using single-lumen tracheal tube (SLT), is our preferred anesthetic technique for ETS. Intrapleural CO(2) insufflation (capnothorax) was used to ensure lung collapse.

EEG bispectral index during carotid endarterectomy.

Purpose: Carotid endarterectomy (CEA) is an established surgical procedure for the treatment of internal carotid artery stenosis. Stroke is the commonest risk factor during CEA, therefore, cerebral monitoring became essential. Currently the EEG bispectral index (BIS) is used as a monitor of depth of anesthesia and it has showed decreasing trend during cerebral ischemia.

Sevoflurane vs isoflurane anaesthesia: a study of postoperative mental concentration and fine motor movements.

Ambulatory anaesthesia is a challenging specialty. Often locoregional techniques are preferred due to the speedy recovery and short hospital stay. However a reasonable number of day-case surgery are performed under general anaesthesia where the recovery of cognitive functions are delayed.
