title: Anesthetic recovery and hemodynamic effects of continuous thiopental infusion versus halothane for maintenance anesthesia in patients undergoing ocular surgery.
abstract: OBJECTIVE
  To investigate anesthesia recovery and hemodynamic status in patients under thiopental infusion or halothane maintenance anesthesia undergoing ocular surgery.
  
  
  METHODS
  Fifty-nine voluntary patients undergoing ocular surgery in Farabi hospital were allocated to one of two maintenance anesthesia groups: inhaled halothane, 0.8 to 1 per cent, (group I, n=37) and thiopental infusion, 10 to 12 mg/kg/hour, (group II, n=22). Hemodynamic parameters were recorded at the time of patient entrance to the operation room and at the 1, 2, 5, 10, 15, 20, 25, 30, 35, and 40 minutes following anesthesia. Anesthesia recovery variables were also compared between the two groups.
  
  
  RESULTS
  In group I, arterial blood pressure at 10 to 40 min and heart rate at 1 and 25 min after the administration of anesthetics were significantly lower when compared with group II (W ²= 25.10, p= 0.005). Arterial oxygen saturation was similar in the two groups over the whole points of time. The time intervals between the end of surgery and beginning of the first body movements and respiratory efforts were significantly longer in group received halothane (p<0.001).
  
  
  CONCLUSIONS
  Continuous infusion of thiopental can be applied effectively and safely for maintenance of anesthesia. In comparison with halothane, it is associated with lower changes of intraoperative hemodynamics and faster anesthesia recovery.
