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 augmenting the reduction 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.

- Mean Arterial Blood Pressure Change [ Time Frame: 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 ]effect of intervention on the change of mean arterial blood pressure allover study period
- Changes in Surgical Field Visibility [ Time Frame: scale was assessed by the surgeon every 15 minutes from the start of surgical procedure till the end ]
according to change in Fromm and Boezaart surgical field category scale ranging from 0 (no bleeding) to 5 (severe bleeding) where: 0 No Bleeding.
- Slight bleeding- no blood suctioning required.
- Slight bleeding- occasional blood suctioning required.
- Slight bleeding- frequent blood suctioning required, operative field is visible for some seconds after evacuation.
- Moderate bleeding- frequent blood suctioning required, operative field is only visible immediately after evacuation.
- Severe bleeding- constant blood suctioning required, bleeding appears faster than can be removed by suction .Surgery is hardly possible, and sometimes impossible.
- Heart Rate Change [ Time Frame: 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 ]effect of intervention on the change of heart rate allover study period
- Number of Patients Who Recieved Intraoperative IV Nitroglycerin During Operative Procedure [ Time Frame: at the end of surgery ]need for additional intraoperative IV vasodilators (nitroglycerine
- Number of Patients Who Recieved Intraoperative IV Propranolol During Operative Procedure [ Time Frame: at the end of surgery ]the need for additional beta blockers (propranolol)
- Number of Patients Who Recieve Both IV Nitroglycerin and Propranolol During Operative Procedure [ Time Frame: at the end of surgery ]need for both IV nitroglycerine and propranolol intraoperatively
- Blood Loss [ Time Frame: at the end of surgery ]total intraoperative blood loss (mL)
- Change in Postoperative Visual Analogue Score (VAS) for Pain [ Time Frame: 1, 3 and 6 hours after recovery ]VAS for pain score where 0 is no pain and 10 severe intolerable pain
- Surgeon Satisfaction (Categorical) [ Time Frame: at the end of surgery ]surgeon satisfaction score where given 5 for very satisfied, 4 for satisfied, 3 for neutral, 2 for dissatisfied and 1 for very dissatisfied then number of satisfied (satisfaction score = 5) and disatisfied (satisfaction score less than 5) surgeons was compared between groups
