Abstract
High morbidity and mortality during general anesthesia imply that anesthesia in horses must be carried out appropriately. The longer the animal is under anesthesia, the higher the morbidity and mortality. This paper reports on one successful case of using a combination of parenteral anesthesia and inhalation anesthesia in surgery performed at the Veterinary Teaching Hospital, IPB University. This combined anesthesia was used in GTCT surgery of the mare horse, 14 years old, thoroughbred came with a history of stallion-like aggression, anestrous, and nymphomania. Transrectal ultrasonography was the performed and found the right ovary was grossly enlarged. The diagnosis of GTCT was then confirmed. Blood panel test was performed before the surgery. A combination of parenteral anesthesia and inhalation anesthesia was carried out in this GTCT removal surgery on September 11, 2019. Parenteral general anesthesia was administered as induction and maintenance of anesthesia using inhalation anesthesia (Isoflurane) of 2 - 2.5% MAC which was given with oxygen to the patient via ETT (Endotracheal Tube). The use of combined parenteral anesthetics and inhalation anesthetics, in this case, was successfully seen from physical parameters during surgery until post-surgery was within the safe range (HR 32-44 BPM- RR 8-12 x /min- T 36oC - 37.8oC- and SPO2 94 % - 99 %) and the animal recovers 10 - 15 min after the inhalation anesthetic is turned off. This is the first successful combination of parenteral and inhalation anesthesia performed in GTCT surgery in Indonesia.
