The objective of this study was to analyze how preoperative glucose treatment influences the blood glucose level as a measured exponent of surgical stress and to establish the best postoperative replacement considering glucose solutions and insulin. This prospective clinical trial involved 208 non-diabetic patients with normal glucose tolerance, who underwent major surgical procedures and needed 24 hours ICU monitoring postoperatively. Patients were randomly given 5% glucose solution (1000 mL) one day before surgery or after overnight fasting.

Methods: In this prospective study, conducted over a period of three years, 1,104 patients referred for a same day GI endoscopy procedure were analyzed. All patients were given a propofol bolus (0.
The aim of the study was to compare the effect of sevoflurane and propofol anesthesia on myocardial contractility during laparotomic cholecystectomy using transesophageal echo-Doppler. In the study, 40 patients were randomized into two groups, depending on whether they received sevoflurane or propofol anesthesia. Heart rate, cardiac index, stroke volume, left ventricular ejection time and acceleration were measured 10 minutes after induction of anesthesia, 1 minute and 25 minutes after incision.

Benzodiazepines are most commonly used, often in combination with pethidine. Our study compares sedation with propofol to midazolam and colonoscopy without sedation.
