  Occasionally,anesthesiologists may take responsibility of veterinary anesthesia in some researches or studies. There are many anesthetic methods which depend on the nature of the operation;its magnitude,site and duration. Our group tries to choose the simple and safe anesthetic method for laparoscopic cholecystectomy in pigs.
  Totally 29 pigs were studied,7 pigs were anesthetized simultaneously,age between 3-4 months,weight 20-25 kg. Ketamine 100 mg,midazolam 5 mg,atropine sulfate 0.6 mg were injected intramuscularly for induction. After the pig fell asleep,we started intravenous fluid at the ear,adding nembutal 50 mg intravenously before intubation,using endotracheal tube No. 5.0-6.0. During operation ketamine infusion and nembutal 25-50 mg were given intravenously for proper anesthetic level.
  Anesthetic time was about 64 minutes. Average anesthetic doses : nembutal was 132 mg/hr,ketamine was 144 mg/hr. The pigs were extubated within 30 minutes after operation. All were well and still alive till now.
