A rectal suppository of indomethacin (25 mg) was used to prevent labor during the alcohol/control infusion. An IV catheter was placed into the saphenous vein for blood collection and another catheter was placed into the cephalic vein for IV sodium chloride infusion. Animal monitoring of vital signs and depth of anesthesia consisted of electrocardiography, pulse oximetry, capnography, noninvasive blood pressure, and temperature measurements. A gastric catheter was introduced into the stomach and the drink mixture was administered over 10 minutes.
