Dexmedetomidine vs Fentanyl on Time to Extubation in Patients Undergoing Laparoscopic Sleeve Gastrectomy
Study Details
Study Description
Brief Summary
This study aims to compare the efficacy of dexmedetomidine versus fentanyl during general anesthesia for patients with morbid obesity undergoing laparoscopic sleeve gastrectomy.

Detailed Description
The use of opioids in surgeries for patients with morbid obesity is controversial since they are known for having ventilatory depressing effects. Therefore, alternative analgesics are needed to improve anesthetic management for patients with obesity.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Group F (fentanyl group) Fentanyl (1 μg/kg) was given intravenously slowly over 60 seconds before induction of anesthesia as a loading dose followed by continuous infusion at a rate of (1μg/kg/hr) after intubation. It was stopped 10 minutes before the end of surgery. |
Drug: Group F (fentanyl group)
Fentanyl (1 μg/kg) was given intravenously slowly over 60 seconds before induction of anesthesia as loading dose followed by continuous infusion at a rate of (1μg/kg/hr) after intubation and was stopped 10 minutes before the end of surgery.
|
| Experimental: Group D (dexmedetomidine group) The patients were received a loading dose of dexmedetomidine (1 μg/kg) intravenously over 15 minutes before induction of anesthesia, followed by continuous infusion at a rate of (0.6 μg/ kg/ hr) after intubation and was stopped 10 minutes before the end of surgery. |
Drug: Group D (dexmedetomidine group)
The patients received loading dose of dexmedetomidine (1 μg/kg) (Precedex, Abbot Laboratories Inc., Abbot Park, IL, USA) intravenously over 15 minutes before induction of anesthesia followed by continuous infusion at a rate of (0.6 μg/ kg/ hr) after intubation and was stopped 10 minutes before the end of surgery.

Outcome Measures
Primary Outcome Measures
- The time for extubation [30 minutes till end of surgery.]
Time from end of anesthesia till safe extubation of the patients
Secondary Outcome Measures
- Mean arterial blood pressure (MAP) [Intraoperatively.]
Mean arterial blood pressure will be recorded (baseline, after induction, after tracheal intubation, at trochers insertion, during insufflation, at regular intervals throughout the surgery (every 5 minutes) until the end of surgery.
- Heart rate (HR) [Intraoperatively]
Heart rate will be recorded (baseline, after induction, after tracheal intubation, at trochers insertion, during insufflation, at regular intervals throughout the surgery (every 5 minutes) until the end of surgery.
- Incidence of hypotension [Intraoperatively]
Mean arterial blood pressure (MAP)<60mmHg. Ephedrine (5 mg) and 250 ml fluid bolus will be given if MAP < 60 mmHg or decrease 20% of the baseline value.
