RESUMO
Background and Objective: Dental treatments cannot be always performed under local anesthesia in pediatric non-cooperative patients. For this purpose, different anesthetic techniques have been applied to increase patient comport to dental treatments
Methods: Sixty children classified as ASA I-II, between aged 3 to 9, who were scheduled to undergo tooth extraction, were enrolled for this randomized study. Group K received 1 mg/kg ketamine, Group P received 1 mg/kg propofol, and Group KP received 0.5 mg/kg propofol plus 0.5 mg/kg ketamine intravenously for anesthesia induction
Results: Recovery time was significantly lower in Group P than Group KP. No significant differences were found between groups regarding HR, before and after the induction, at tenth minute. Fifth minute's HR was higher in Group K than Group KP. Mean arterial pressure [MAP] values were similar at baseline, before and after the induction, and at tenth minute, whereas significantly lower values were found in Group P and Group KP than in Group K at fifth minute
Conclusions: Although ketamine, propofol and ketamine-propofol combination are effective for sedation in tooth extraction in pediatric patients, propofol may be an excellent alternative, with the shortest recovery, no nausea and vomiting, and reasonable surgical satisfaction
RESUMO
To investigate the use of 3 different doses of ropivacaine on the quality of anesthesia and hemodynamics in epidural anesthesia for transurethral surgery. The current study was conducted in the Department of Anesthesiology, Medical Faculty of Erciyes University, Turkey, between May 2004 and June 2006. The study recruited 81 males of ASA I- II group, ages 60-80 years, undergoing transurethral resection of prostate or bladder tumors. Patients were randomly assigned to 3 groups receiving epidural ropivacaine in different doses and concentrations. Group I n = 27 received 15 ml 102.5mg of 0.75% solution, group II n = 27 received 10ml 75mg of 0.75% solution, and group III n = 27 received 10 ml 50mg 0.5% ropivacaine. The quality of the blocks and the hemodynamic changes were compared. Motor block was significantly less in group III than in groups I and II. The sensory block level was T6 or more in 55% of patients in group I, 35% in group II, and 21% in group III. The duration of sensory block was less, and the time to achieve the T10 level was greater in group III. Hypotension and bradycardia were more frequent in group I. Effective anesthesia with few side effects was obtained with low dose ropivacaine
