Factors associated with survival in septicemic foals: 65 cases (1988-1995).
- Journal Article
Summary
The research article explores factors linked to survival rates in septicemic foals, analyzing the health data of 65 foals diagnosed with septicemia to determine which variables can predict survival.
Objective of the Research
The study aimed to identify variables at admission that could predict the survival of septicemic foals—foals diagnosed with septicemia, a serious bloodstream infection. The researchers used medical records of 65 such foals for analysis.
Method of Analysis
The medical records analyzed in this study included important details such as:
- Physical examination and historical data
- Hematologic and serum biochemical variables determined at admission
These variables were initially analyzed independently (univariate analysis) for any correlation with survival.
Significant Findings
The univariate analysis discerned several factors significantly associated with survival, such as:
- Ability to stand at admission
- Respiratory rate of 60 breaths per minute or more
- Presence of normal-appearing mucous membranes
- White blood cell count of 6,000 cells/microL or more
- Neutrophil count of more than 4,000 cells/microL
- Serum albumin concentration greater than 2.2 g/dL
- Serum glucose concentration of over 120 mg/dL
- Blood pH of 7.35 or above
- Positive base excess
- Administration of plasma at admission
However, foals with a history of induced parturition were less likely to survive.
Further Analysis and Findings
The doctors then performed a stepwise multiple logistic regression analysis on the variables identified as significantly associated with survival. This multivariate model included the ability of the foal to stand, the duration of clinical signs before admission, respiratory rate, neutropenia, and neonatal age category.
The probability of survival was significantly increased for foals that were standing, had a respiratory rate of 60 breaths per minute or more, and a neutrophil count above 4,000 cells/microL at admission. However, each 24-hour interval of the duration of clinical signs prior to admission significantly decreased the probability of survival, increasing the estimated risk of death by 5.8-fold.
