ABSTRACT

ObjectiveTo investigate the effects of pre-infusion of hypertonic sodium chloride hydroxyethyl starch 40(HH40)injection in prevention for transurethral electroresection of the prostate syndrome(Tuns).MethodsSixty patients with benign prostate hyperplasia(ASA)grades Ⅱ toⅢwere recruited in the study and randomly divided into two groups,one injected intravenously with HH40 at dose of 5 ml/kg by drip after sursical operation a8 experiment and the other injcoted with the same volume of Ringer's solution as control Mcan arterial pressure,heart rate,saturation of blood oxygen(SaO2)and central venous pressure were monitored for all the patients.In addition.serum concentrations of sodium,potassium,chloride and serum osmolality were determined before(T0)and 30 min(T30)and 60 min(T60) after operation,respectively,as well as pH valRe and partial pressure of carbon dioxide(PgCO2)in the gastric mucosa were determined by a Tonocap monitor.Occurrence of TURS and use of atropine,ephedrine and rinse solution were documented.Resuits TURS occurred in four patients in the eontrol group during surgical operation,whereas uo TUns occurred in experimental group.Serum sodium concentration was (126.5±13.3)mmoL/L at T60 in control group,significantly lower than that in experimental group(P＜0.05),while intragastric pH value and PgC02 level were(7.26±0.04)and(54±9)mm Hg[(7.2±1.2)kPa],respectively in controls,significantly higher than those in experimental group(P＜0.05).ConclusionsPre-infusion with HH 40 can improve tissue perfusion and prevent effectively from TURS in patients with transurethral electroresection of the prostate.
