BACKGROUND Existing data suggest that obesity correlates with airway hyper-reactivity. However, the incidence of bronchospasm during bariatric surgery in obese patients has not been well studied. METHODS This was a prospective observational study comparing 50 obese versus 50 non obese patients undergoing elective laparoscopic surgery over a 2 year period. Bronchospasm was detected clinically ...

Purpose. To compare a semiopen breathing circuit with a non-rebreathing (Hudson mask) for MRI experiments involving gas delivery. Methods and Materials. Cerebral blood flow (CBF) was measured by quantitative phase contrast angiography of the internal carotid and basilar arteries in 18 volunteers (20-31 years). In 8 subjects, gases were delivered via a standard non-rebreathing (Hudson mask). In ...

the intraoperative care of pheochromocytomas can be difficult and lead to serious complications. we present a case of a 46 year-old female undergoing laparoscopic resection of pheochromocytoma, who was scheduled for surgery with phenoxybenzamine and amlodipin. under general anesthesia cardiovascular stability was achieved by peritumoral infiltration of lidocaine during resection.

Isoflurane is the anesthetic of choice for most avian anesthetic procedures. However, inhalation anesthesia is not always available in field situations involving wild birds, although small portable inhalation anesthesia units are available. Certain surgical procedures, such as tracheal resection, may warrant the use of injectable anesthesia regardless of whether or not an anesthesia machine is ...

in order to investigate the effect of different temperature of anesthetic (clove tree) and recover (anesthetic-free water) solutions on recovery process, the anesthetic induction times and recovery times of 540 fingerlings of rainbow trout (oncorhynchus mykiss) weighing 3.2 ± 0.2 g in anesthesia/ recovery solutions with cross-combined of temperature of 5,11 and 17 °c as experimental treatments ...

BACKGROUND For patients undergoing general anesthesia, adequate warming and humidification of the inspired gases is very important. The aim of this study was to evaluate the differences in the heat and moisture content of the inspired gases with low-flow anesthesia using 4 different anesthesia machines. METHODS The patients were divided into 11 groups according to the anesthesia machine used ...

introduction: intravenous general anesthetic agents are among the most important and widely used anesthetic drugs in the clinical practice. many pharmacological studies have shown that potentiation of gaba and glycine on their receptors is the most plausible mechanism. nevertheless, there is limited information on the effects of co-administration of two or more of these agents. however, experim...
