Dosage of Propofol Based on Lean Body Weight

Patients who will be anesthesia induced with propofol will be body analyzed with Tanita before the operation. Height, weight, age, gender and other general information of the patients will be recorded. Total body weight (TBW), ideal body weight (IBW) and lean body weight (LBW) will be calculated. Patients over 18 years of age who will be operated under general anesthesia for 2-6 hours will be included. Patients allergic to propofol or contraindicated to propofol will be excluded. In the study, in order to decide and test the most appropriate weight-based scale for the evaluation of propofol dosage for induction of anesthesia by identifying patients who need additional propofol during intubation, Ingrande et al. After monitoring, propofol infusion (100 mg/kg/hour) will be started according to total body weight and the infusion will be stopped when the BIS value is between 50 and 40 and the elapsed time will be recorded. Routine anesthesia applications will be performed by applying neuromuscular blocker. Total Propofol dose administered will be calculated according to the dose TBW, IBW and LBW in kilograms. The relationship between the doses administered and body mass index will be evaluated.

Patients over 18 years of age who will be operated under general anesthesia for 2-6 hours will be included. Patients who are allergic to propofol or for whom propofol is contraindicated will not be included in the study. In the study, 80 patients with a mean body mass index \[BMI\] between 18-35 and Bispectoral index (BIS) (Ingrande et al. ) monitoring, propofol infusion (100 mg/kg/hour) will be started according to total body weight, and when the BIS value is between 50 and 40, the infusion will be stopped and the elapsed time will be recorded in order to decide and test the most appropriate weight-based scale for propofol dosing for anesthesia induction to identify and evaluate patients who need additional propofol during intubation. Routine anesthesia will be performed by applying neuromuscular blocker. Total Propofol dose administered will be calculated according to TBW, IBW and LBW per kilogram. And the relationship between the doses given and body mass index will be evaluated. In our study, we aimed to evaluate the effects of Propofol dose according to lean body weight by evaluating patients with a body mass index below 35.Patients who will undergo anesthesia induction with Propofol will undergo preoperative body analysis with Tanita. Height, weight, age, gender and other general information of the patients will be recorded. Total body weight (TBW), ideal body weight (IBW) and lean body weight (LBW) will be calculated. Patients over 18 years of age who will be operated under general anesthesia for 2-6 hours will be included.
