Reliable and Rapid Smooth Extubation After Ketofol for Induction of General Anesthesia in Laparoscopic Drilling of Polycystic Ovary: A Randomized Controlled Trial.

After securing intravenous access by a 20g catheter, intravenous premedication (midazolam 2 mg and 4mg ondansetron) was administered to all patients. Standard ASA(american society of anesthesiologists) monitoring (5-lead ECG, noninvasive blood pressure (NIBP), and pulse oximetry) was applied to all the patients for the recording of heart rate (HR), NIBP and oxygen saturation by a multiparameter monitor. Induction of general anesthesia was achieved as follows: in Group K (Ketofol group), fifty three female patients received propofol (1mg/kg) plus ketamine (0.5mg/kg) at the induction of general anesthesia while in Group P (Propofol group), fifty three female patients received propofol (2mg/kg) only at the induction of general anesthesia.

Patients in both groups received fentanyl 2 ug\kg and atracurium 0.5 mg\kg. After tracheal intubation, general anesthesia maintained by isoflurane 1.5 volume % in 2 L\min oxygen-air mixture 50:50 and atracurium 0.1 mg\kg every 30 minutes, if needed. At the end of the surgery, inhalational anesthesia was stopped and reversal of the patients was done by injection of neostigmine 0.05mg\ kg and atropine 0.01mg\kg.

Hemodynamics (HR and mean arterial pressure ''MAP'') was assessed at 5 minutes interval from the time of reversal of muscle relaxant up to 30 minutes after extubation.

The level of sedation during suction and extubation was assessed using observer assessment sedation score and the airway response under direct laryngoscopy to suction was noted by five-point scale. After 5 minute interval, the level of sedation and smoothness of extubation was noted by four-point scale.
