NCT03850093

Brief Summary

the current study hypothesized that Gabapentin can be effective as Bisoprolol in reduction of intraoperative bleeding, improving the operative's field visibility and increase the surgeon satisfaction via optimization of blood pressure and heart rate . A prospective randomized double blinded controlled study. Eligible patients were randomized according to random list generated software and allocated into 3 equal and matched groups (15 patients in each group):-

  • Group G: gabapentin group in which Patients were premedicated with oral gabapentin 1200 mg (Conventin 400mg; Evapharm) with sips of water, 2 hours before induction of anesthesia.
  • Group B: bisoprolol group in which Patients were premedicated with oral bisoprolol 2.5 mg ( Concor 2.5mg ; Merck/Amoun ) with sips of water, 2 hours before induction of anesthesia.
  • Group C: control group in which Patients were premedicated with oral placebo with sips of water, 2 hours before induction of anesthesia.

Outcome Measures

Primary Outcomes (2)

  • Changes in Surgical Field Visibility

    according to change in Fromm and Boezaart surgical field category scale ranging from 0 (no bleeding) to 5 (severe bleeding) where: 0 No Bleeding. 1. Slight bleeding- no blood suctioning required. 2. Slight bleeding- occasional blood suctioning required. 3. Slight bleeding- frequent blood suctioning required, operative field is visible for some seconds after evacuation. 4. Moderate bleeding- frequent blood suctioning required, operative field is only visible immediately after evacuation. 5. Severe bleeding- constant blood suctioning required, bleeding appears faster than can be removed by suction .Surgery is hardly possible, and sometimes impossible.

    scale was assessed by the surgeon every 15 minutes from the start of surgical procedure till the end

  • Blood Loss

    total intraoperative blood loss (mL)

    at the end of surgery

Secondary Outcomes (2)

  • Heart Rate Change

    were recorded before oral premedication (baseline), pre-induction, after induction of anesthesia, 1, 5, 10, 15 minutes after intubation and then every 15 minutes until the end of surgery

  • Mean Arterial Blood Pressure Change

    were recorded before oral premedication (baseline), pre-induction, after induction of anesthesia, 1, 5, 10, 15 minutes after intubation and then every 15 minutes until the end of surgery

Other Outcomes (7)

  • Surgeon Satisfaction (Categorical)

    at the end of surgery

  • Number of Patients Who Recieved Intraoperative IV Nitroglycerin During Operative Procedure

    at the end of surgery

  • Number of Patients Who Recieved Intraoperative IV Propranolol During Operative Procedure

    at the end of surgery

  • +4 more other outcomes
