Effect of Anesthesia on Frontal QRS t Angle in Obese Individuals

All patients were routinely administered 500 cc of Ringer's lactated solution intravenously (IV) before anesthesia and taken to the operating room. The body mass index will be calculated according to the formula body weight kg / height cm2. Obese patients with a BMI above 30 kg/m2 were recorded as group 2, and non-obese patients with a BMI below <30 kg/m2 were recorded as group 1. Patients were taken to the operating room and routine ECG, noninvasive blood pressure, pulse, and oxygen saturation monitoring (CARESCAPE™ B650, GE Healthcare, USA) was performed. All patients were hydrated intravenously (IV) with 500 cc of Ringer's lactated solution after a 6-hour fast. For premedication, midazolam 1 mg IV and pantoprazole 40 mg IV were administered. For anesthesia induction, propofol 2 mg/kg, fentanyl 2 mg/kg and rocuronium 0.6 mg/kg were administered intravenously.
