Prognostic indicators for horses with duodenitis-proximal jejunitis. 75 horses (1985-1989)

The medical records of 75 horses with duodenitis-proximal jejunitis (DPJ) were reviewed. Ages, physical parameters, laboratory values, and treatment data were compared between horses surviving DPJ and horses not surviving DPJ (Table 1). Fifty of 75 horses (66.6%) survived. Sixty-six horses (88.0%) were managed with medical treatment alone and nine horses (12.0%) were managed with medical treatment plus surgical intervention. Using a logistic regression model, the association of each of the 19 physical and laboratory parameters with death was evaluated retrospectively in the 75 horses. Three parameters (anion gap, abdominal fluid total protein concentration, and volume of gastric fluid for the first 24 hours of hospitalization) were significantly associated with death by univariate analysis. Using a stepwise multiple logistic regression, two parameters remained significantly associated with death (P < 0.05), anion gap and abdominal fluid total protein concentration.
