Abstract

The Confidential Enquiry into Perioperative Equine Fatalities (CEPEF-1) is an observational multi-institutional prospective study of recovery outcome at 7 days post operatively, as called for by Steffey (1991). Data from 6,255 general anaesthetics (February 91-March 93) were submitted confidentially by 62 clinics. The outcomes of 333 cases which were subjected to euthanasia and which were not classified 'alive' or 'died' at 7 days, were excluded from the analysis. The remaining 5922 cases were analysed to identify risk ratios (RR) between survivors and nonsurvivors for a variety of factors. These preliminary results indicate an overall death rate, for equine patients dying or being subjected to euthanasia within 7 days of a general anaesthetic because of perioperative complications, of 102/6255 (1.6%). This mortality rate decreased to 46/5220 (0.9%) when all colic surgery and delivery of foals under general anaesthesia were excluded. There was an increased risk formares in the last trimester of pregnancy (RR=6.4). Patients undergoing emergency abdominal procedures (colic patients and pregnant mares undergoing controlled or caesarean section delivery of foals) under general anaesthesia were at increased risk (RR=12.9) compared to ear, noseand throat surgery. Within orthopaedic surgery, patients requiring internal fixation were at increased risk (RR=3.2) compared to those undergoing miscellaneous orthopaedic surgery. There was no difference in risk between breeds. Patients not placed in dorsal recumbency were at reduced risk (RR=0.3-0.5) compared to those which were in dorsal recumbency. Lack of a sedative premedication and use of xylazine were associated with a RR of 6.2 and 2.1 respectively, compared to patients givenonly detomidine for sedative premedication. However, 90% of all induction regimes were at similar risk, except inhalation with halothane (RR=4.8) and guaiphenesin and ketamine combination (RR=4.3) compared to guaiphenesin and thiopentone combination. There was a reduction in risk for surgeries carried out in the last quarter of the year (RR=0.3), compared to surgery carried out in the first three-quarters. Patients younger than 1-week-old (RR=20.6) and between 1-week and 1-month-old (RR=4.3) and patients older than 12 years old (RR=3.1) were at increased risk, compared to patients age 2-4 years. The likelihood of death increased as the duration of anaesthesia increased beyond 61 min, with the greatest being operations lasting longer than 241 min (RR=7.6). Surgery performed outside of 0900-1700 h had increased risk, worst between 1801-2000 h (RR=9.9), compared to surgeries carried out between 0801-1300 h.
