Prophylaxis of TUR-P syndrome with CVP messurement and blood gas analysis During combination Transcervical-Laparoscopic Resection of Endometrium

Abstract

Objective To observe the changes of central venous pressure and blood gas analysis during combination transcervical-lanaroscopic resection of endometrium. Methods We used 0.9% saline solution as distending medium for 24 cases of operative hysteroscopy. Those patients were divided into two groups, In group CVP, the patients were contineous measured CVP during the operation, when the CVP was higher than 12mmHg, the blood gas was also measured and intravenous lasix. and in group non-CVP, the time was longer than 60 minutes. Plasma sodium, potassium, and PH value were measured. When plasma potassiumwas lower than nomal value, also gave lasix to the patients. Results None of the CVP group cases presented with transurethral resection of prostate ( TURP ) syndrome. But 2 cases of non-CVP patients presented with TURP syndrome. Plasma potassium ( 2.8 ± 0.40 ) mmol/L and PH value ( 7.2 ±0.17 )were found lower in non-CVP group patients than in CVP group patientg P＜ 0. 05 ). Conclusions CVP measurement and blood gas analysis were safe and iand could be widely applied in combination transcervical-laparscopic resection of large endometrium.
