Remifentanil preventing hemodynamic changes during laparoscopic adrenalectomy for pheochromocytoma.

In this prospective case-series study, a balanced anesthetic scheme of sevoflurane in nitrous oxide supplemented with remifentanil and sustained neuromuscular block was applied in nine patients scheduled for laparoscopic adrenalectomy for pheochromocytoma. Laparoscopic adrenalectomy to treat pheochromocytoma results in marked catecholamine release during pneumoperitoneum and tumor manipulation. Remifentanil infusion was adjusted to maintain systolic arterial pressure between 120-170 mmHg.

The influence of premedication and smoking.

The history of smoking and premedication did not influence the proportion of patients who had a cough response to fentanyl when administrated as first agent during induction in anesthesia.

Mechanisms of ketamine action on lipid metabolism in rats.

Background And Objective: This study was conducted to determine the effect of ketamine on metabolic homoeostasis and particularly in lipoprotein lipase (LPL) activity in adipose tissue.

Methods: Sixty male Wistar rats were divided into six groups of 10 each. Group A served as controls, while Groups B-F received, respectively, ketamine 60, 80, 100, 120 and 140 mg kg(-1) intraperitoneally.

Lipid kinetics in obese patients undergoing laparoscopy. The impact of cortisol inhibition by etomidate.

The aim of this study was to investigate the response of cortisol, insulin and lipid parameters [serum Lipoprotein Lipase activity, choleseryl-ester transfer protein, triglycerides, total Cholesterol, High Density Lipoprotein, Free Fatty Acids] during the perioperative period in obese patients undergoing laparoscopic cholecystectomy. Twenty obese patients were included and divided in two groups. In group A (n=10) patients were anaesthetized with propofol and group B (n=10) with etomidate.
