Objective: To determine the cardiovascular effects of desflurane in dogs following acute hemorrhage. Design: Experimental study. Animals: Eight mix breed dogs. Interventions: Hemorrhage was induced by withdrawal of blood until mean arterial pressure (MAP) dropped to 60 mmHg in conscious dogs. Blood pressure was maintained at 60 mmHg for 1 hour by further removal or replacement of blood. Desflurane was delivered by facemask until endotracheal intubation could be performed and a desflurane expiratory end‐tidal concentration of 10.5 V% was maintained. Measurements and main results: Systolic, diastolic, and mean arterial blood pressure (SAP, DAP and MAP), central venous pressure (CVP), cardiac output (CO), stroke volume (SV), cardiac index (CI), systemic vascular resistance (SVR), heart rate (HR), respiratory rate (RR), partial pressure of carbon dioxide in arterial blood (PaCO2), and arterial pH were recorded before and 60 minutes after hemorrhage, and 5, 15, 30, 45 and 60 minutes after intubation. Sixty minutes after hemorrhage, SAP, DAP, MAP, CVP, CO, CI, SV, PaCO2, and arterial pH decreased, and HR and RR increased when compared with baselines values. Immediately after intubation, MAP and arterial pH decreased, and PaCO2 increased. Fifteen minutes after intubation SAP, DAP, MAP, arterial pH, and SVR decreased. At 30 and 45 minutes, MAP and DAP remained decreased and PaCO2 increased, compared with values measured after hemorrhage. Arterial pH increased after 30 minutes of desflurane administration compared with values measured 5 minutes after intubation. Conclusions: Desflurane induced significant changes in blood pressure and arterial pH when administered to dogs following acute hemorrhage. 相似文献

Dynamic left ventricular outflow tract obstruction (DLVOTO) is a common condition in cats
and humans. In this case report, a dog is described with DLVOTO secondary to severe
intra-abdominal hemorrhage caused by a hemangiosarcoma. The dog was a 9-year-old, 35.7-kg,
spayed female German Shepard dog that presented with a history of tachypnea and collapse.
A Levine II/VI systolic murmur was present at the heart base. Abdominal ultrasonography
revealed a splenic mass and a large amount of ascites. Echocardiography showed a reduced
left ventricular diameter and an increased aortic velocity caused by systolic anterior
motion (SAM) of the mitral valve apparatus. The heart murmur and the SAM were resolved
after treatment including a splenectomy and a blood transfusion. 相似文献

Patient monitoring in the operating theatre requires a high level of vigilance by anesthetists. The aim of this paper is to report the design of a clinically useful diagnostic system called real-time smart alarms for absolute hypovolemia in anesthesia monitoring (RTSAAM). The system provides decision support to the anesthetist by presenting the diagnostic results on an integrative, ergonomic display that is hoped to enhance patient safety. The performance of the system is assessed by both offline testing and real-time testing in the operation theatre. When detecting absolute hypovolemia (AHV) a satisfactory level of agreement (up to 81%) is observed between RTSAAM and the anesthetist. 相似文献
