Isoflurane anesthesia was evaluated for use in cesarean-section delivery of specific-pathogen-free (SPF) pigs. Pregnant gilts were premedicated with atropine sulfate (0.05 mg/kg) and azaperone (2 mg/kg) and then anesthetized by inhalation of 4% isoflurane delivered in a mixed gas (N2O : O2 = 1 : 2) through a face mask. After anesthetization, local infiltration anesthesia with procaine hydrochloride was performed at the incision site. While nociceptive reactions were being monitored at 4 to 7 minutes after anesthetization, isoflurane concentration was reduced to 0.5% and maintained at this level until completion of delivery. A small amount of isoflurane (31.4 +- 4.1 MAC-min) resulted in high yields of live piglets (95.8 +- 6.9%) with no notable adverse effects on the gilts
