Abstract

Thirty-six dogs under chloralose anesthesia were studied in groups of six. Arterial pressure (BP), central venous pressure (CVP), intracranial pressure (ICP), and arterial blood gases were monitored. The group underwent: 1) anesthesia only; 2) phlebotomy (P) (40% of blood volume) and reinfusion (RI) of half the shed blood plus Ringer's lactate solution; 3) P followed by pneumatic trousers (PT), and then RI; 4) inflation of an epidural 2-cc Foley catheter (EFC); 5) P followed by EFC and then RI; and 6) P followed by EFC and then by PT and RI. Group 1 was stable. In Group 2, P lowered BP (49 torr systolic ± 6 SEM), CVP, and ICP. RI restored these. In Group 3, the PT improved BP (P < .05) without increasing ICP. In Group 4, EFC increased ICP (P <.05) to 15 ± 4 torr. In Groups 5 and 6, ICP was not significantly increased by EFC or PT and RI.
