Abstract

A partial intravenous protocol was used successfully to maintain anaesthesia in 5 healthy horses. Horses were premedicated with acepromazine, romifidine and butorphanol, induced with guaifenesin and ketamine and maintained on a constant rate infusion of lidocaine, ketamine and medetomidine together with halothane inhalation anaesthesia. Mean end-tidal halothane concentration to maintain a surgical plane of anaesthesia was 0.8 ± 0.2 %. Mean dobutamine requirement to maintain mean arterial pressure above 9.31 kPa was 0.42 ± 0.3 µg/kg/min. The administration of relatively low doses of lidocaine, ketamine and medetomidine together with halothane resulted in haemodynamically stable anaesthesia, followed by smooth recovery.
