ABSTRACT:
This study evaluated the quality of anesthesyc recovery of horses using a three-point assisted method. Sixty-eight horses (37 females and 31 males) of different breeds, age and weight submitted to general anesthesia for abdominal - ABD (n=15), arthroscopy - ART (n=17), other orthopedic - ORT (n=18) and miscellaneous - MIX (n=18) surgical procedures. Isoflurane resulted in shorter recovery time (67.4±25.7min) compared to halothane (88.0±37.8min). The mean duration (±SD) of anesthesia for ABD, ORT, ART and MIXgroups was 166.7 (±14), 54.9 (±5.9), 86.5 (±7.3) and 76.4 (±32.5) minutes (min) respectively. Quality of recovery wasn’t influenced by duration of anesthesia or by use of analgesic, sedative and/or anesthetic drugs or not (p>0.05). Mean standing time (TEst) during anesthetic recovery was 67.5 (±29.9) min in ABD, 44.4 (±27) min in ORT, 42.2 (±23.2) min in ART and 39 (±14.7) min in MIX group. Average number of attempts (Ast) to stand was 1.8 (±0.8) in ABD group, 3.1 (±4.7) in ORT, 1.8 (±1.2) in ART and 1.8 (±1.2) in MIX. Recovery time (TRec) in ABD group was 102.2 (±36.5) min, ORT 70.1 (±36.5) min, ART 72.2 (±24.8) min and MIX group 66.6 (±19.1) min. TRec differed (p<0.05) between ABDand other groups. Three-point assisted recoveryfrom anesthesia showed to be a safe procedure during horses’ recovery. This method is easy to apply and well tolerated by horses regardless of the surgical procedure.
