Abstract

Transurethral resection of prostate is popular methop, but hemorrhage and absorption of irrigation fluid are most common complications during operation. We have studied changes of blood pressure and central venous pressure during and after of transurethral resection in 32 patients with BPH during the period from january, l985 to january, l986. And we have observed the relationships between blood pressure and central venous pressure change with irrigation fluid volume, resected weight of prostate, resection time and blood loss. The following results were obtained. 1. Among the 32 transurethral resection of prostate, resection time was 67+/-18 min(Mean- S.D.), resected weight of prostate was 22.4+/-11.2gm, irrigation fluid was 24,000ml+/-9,800ml, Blood loss was 456+/-ml280ml. There was significant correlate between resection time, resected weight of prostate, irrigation fluid volume and blood loss. 2. Preoperative blood pressure was l28mmHg+/-l4mmHg/76mmHg+/-9mmHg (systolic/diastolic, Mean+/-S.D.), and it was become 128mmHg+/-l2mmHg/81mmHg+/-8mmHg immediately after spinal anesthesia. After 20min and 40min starting operation, blood pressure were 116mmHg+/-l3mmHg/74 mmHg+/-8mmHg and 112mmHg+/-12mmHg/71mmHg+/-9mmHg, respectively. Blood pressure was returned to nearly preoperative blood pressure on 4 hours after operation, and the blood pressure was 129mmHg+/-11mmHg/82mmHg+/-9mmHg. 3. Preoperative central venous pressure was 6.7cmH2O+/-2.9cmH2O(Mean-S.D.) and it was become 5.9cmH2O+/-2.5cmH2O immediately after spinal anesthesia. After 20min starting operation, central venous pressure were 5.1cmH2O+/-2.7cmH2O and 4.8cmH2O+/-2.OcmH2O respectively. Central venous pressure were returned to nearly central venous pressure of immediate after spinal anesthesia on 4 hours after operation, and the central venous pressure was 5.6cmH2O+/-1.8cmH2O. 4. Blood pressure and central venous pressure changes were correlate in case more than 800ml of blood loss but there was no correlate in cases with loss than 800ml of blood loss.
