To measure cardiopulmonary variables, including cardiac index, in dogs with naturally acquired gastric dilatation-volvulus (GDV).
Prospective clinical study.
6 dogs with GDV.
In addition to typical medical and surgical management of GDV, the dorsal metatarsal and pulmonary arteries and right atrium of the dogs were catheterized to obtain cardiopulmonary measurements before and during anesthesia and surgery.
All dogs underwent gastropexy but none required gastrectomy. Mean cardiac index and mean arterial blood pressure for this small population of dogs with GDV were not significantly different from those reported for clinically normal awake or anesthetized dogs.
Dogs with naturally acquired GDV without gastric necrosis may not have the classic characteristics, including decreased cardiac index and hypotension, of hypovolemic circulatory shock.
测量自然发生胃扩张-扭转（GDV）的犬的心肺变量，包括心脏指数。
前瞻性临床研究。
6只患有GDV的犬。
除了对GDV进行典型的内科和外科治疗外，还对犬的背侧跖动脉、肺动脉和右心房进行插管，以在麻醉和手术前及手术期间获得心肺测量值。
所有犬均接受了胃固定术，但无一需要胃切除术。这一小群患有GDV的犬的平均心脏指数和平均动脉血压与临床正常清醒或麻醉犬的报告值无显著差异。
自然发生GDV且无胃坏死的犬可能不具有低血容量性循环休克的典型特征，包括心脏指数降低和低血压。
