A comparison of auricular, rectal and pulmonary artery thermometry in dogs with anesthesia‐induced hypothermia

摘要: Objective: To determine if a correlation exists among auricular, rectal and pulmonary artery (PA) temperatures in hypothermic dogs. Design: Prospective study. Setting: Angiography suite at college of veterinary medicine. Animals: Sexually intact female research hounds (13.9–25.4 kg; n=8). Measurements main results: Dogs were anesthetized for instrumentation with percutaneously placed, thermistor-tipped, PA catheter. Anesthesia was maintained until the core body temperature decreased to 36.6°C (97.8°F). discontinued, auricular obtained every 15 minutes reached 38.3°C (100.9°F). A strong noted 3 methods measurement (P<0.001; R≥0.846). No statistical difference detected baseline, minimum attained, nor median attained. However, maximum measurements (37.7±0.4°C or 99.8±0.7°F) lower than either (38.3±0.3°C 100.9±0.5°F) (P=0.001). Conclusion: There is rectal, temperatures. Auricular may be used monitor during postoperative rewarming; however, it might slightly as normothermia reached.
