Determine the incidence of early post-operative hypoventilation in post-anesthesia care unit (PACU) in patients undergoing laparoscopic bariatric surgery under opioid-sparing compared with sevoflurane-based anesthesia.
The incidence of early postoperative hypoxemia in the literature is diverse, this may be due to multivariable, including patient-related factors, anesthesia-related factors, and surgery-related factors. Because of the controverse regarding the incidence of postoperative hypoxemia and the evidence of anesthetic technique of choice, interest in prevention and early management of early postoperative hypoxemia after laparoscopic bariatric surgery is continued.

Intraoperative opioid-sparing maintenance comprised dexmedetomidine bolus dose of 1 mcg/kg followed by 0.3 mcg/kg/h, propofol 4-8 mg/kg/h and ketamine 25 mg/h for a max of 50 mg during the procedure, targeting bispectral index (BIS) between 45%-60%. The lean body weight will be used for calculation of the drugs.
Intraoperative sevoflurane-based anesthesia, 0.8 to 1.0 Minimum alveolar concentration will be used combined with fentanyl 1 mcg/kg followed by 1 -2 mcg/kg/h and cis-atracurium, to keep bispectral index between 45% to 60%.

Incidence of Early postoperative hypoventilation
Early postoperative respiratory hypoventilation will be defined by any of the following parameters: Oxygen saturation \< 95% for 10 seconds. Respiratory rate \< 8 breath/min. Apnea spill \> 10 seconds. pain/sedation-mismatch.
Time frame: UP to 24 hours Postoperatively
