Efficacy and safety of remifentanil and sulfentanyl in painless gastroscopic examination: a prospective study.

We aim to assess efficacy and safety of remifentanil or sulfentanyl combined with propofol during painless gastroscopic examination in patients. In this study, 270 patients were randomly divided into 3 groups: propofol was given only in group P; propofol and remifentanil in group PR; propofol and sulfentanyl in group PS during the gastroscopic examination. Efficiency of group P was significantly higher than that of group PR and PS (P<0.

[Protective effects of hydroxyethyl starch (130/0.4) against ischemia reperfusion injury of kidney: experiment with rats].

Objective: To explore the protective effects of hydroxyethyl starch (HES)(130/0.4) against ischemia reperfusion injury of kidney and its impact on the expression of intercellular adhesion molecule-1 (ICAM-1).

Methods: Forty SD rats underwent resection of the right kidney and clamping of the left renal artery for 60 min to establish renal ischemia reperfusion model, and then were randomly divided into 4 equal groups: Group S, undergoing infusion of normal saline 20 mg/kg 20 min before the reopening of the renal artery, Group W1, undergoing infusion of HES 5 mg/kg 20 min before the reopening of the renal artery, Group W2, undergoing infusion of HES 10 mg/kg, and Group W3, undergoing infusion of normal saline 20 mg/kg.
