Using esmolol during anesthetic maintenance of laparoscopic bariatric surgery significantly decreases anesthetic, analgesic requirements, postoperative pain, PNV and postoperative hypoxia.

Postoperative pain, nausea, vomiting (PNV) and hypoxia are common in relation to laparoscopic bariatric surgery. Sympatholytic drugs might decrease the need for intravenous or Inhalation anesthetics and opioids. In this study we wanted to analyze effects of esmolol on intraoperative anesthetic-analgesic requirements, postoperative analgesic requirements, postoperative pain, PNV and hypoxia.

Methods: Sixty patients have been included. Propofol, fentanyl and rocuronium were used for induction. Study groups were as follows; group E Esmolol infusion was added to maintenance anesthetics (Sevoflurane and fentanyl), group N only Sevoflurane and fentanyl was used during maintenance. They have been monitored during the intraoperative period and postoperatively for 24 h for analgesic requirements and PNV. Visual analog scale (VAS) scores for pain was also been assessed.

Inclusion Criteria:

• American Society of Anesthesiologists (ASA) I - II patients
• age between 18-59 years
• both genders
• body mass index (BMI) > 45 kg/m2

Exclusion Criteria:

• Patients with -hepatic
