Pulmonary Gas Exchange and Plasma Lactate in Horses with Gastrointestinal Disease Undergoing Emergency Exploratory Laparotomy: A Comparison with an Elective Surgery Horse Population

摘要: Objective: To characterize pulmonary gas exchange and arterial lactate in horses with gastrointestinal disease undergoing anesthesia, compared elective surgical horses, to correlate these variables postoperative complications mortality. Study Design: Prospective clinical study. Animals: Horses emergency laparotomy for acute intestinal (n=50) healthy surgery dorsal recumbency (n=20). Methods: Arterial blood analysis was performed at predetermined intervals on a standardized anesthetic protocol. Alveolar–arterial oxygen gradient calculated. Predictive factors death colic were determined. Results: tension (PaO2) varied widely among both groups. PaO2 significantly increased the group after exteriorization of ascending colon. alveolar–arterial not different between groups, neither correlated horse outcome. recovery ≥5 mmol/L associated 2.25 times greater relative risk ≥7 mmol/L 10.5 higher death. Conclusion: Colic this population more likely be hypoxemic than nor impaired degree controls. sampled immediately predictive death.
