ABSTRACT
OBJECTIVE To explore and evaluate the efficacy of preventing the central venous catheter-related infection using catheter-sealing separately with gentamicin and heparin.METHODS One hundred and thirty six hemodialysis patients with temporary indwelling central venous catheters were enrolled in this study,and randomly assigned into 3 groups: Group A(catheter-sealing separately with gentamicin and heparin,n=46),Group B(catheter-sealing with gentamicin mixted heparin,n=45) and Group C(catheter-sealing with heparin,n=45).Complications such as infection were monitored.RESULTS Rate of catheter-related infection and intravenous catheter infection were without significant difference between Groups A and B,but were obviously lower than that in Group C(6.5% and 4.4% vs 22.2%,P
ABSTRACT
Fifteen patients with chronic renal failure(CRF)underwent laparoscopic cholecystectomy(LC)at carbon dioxide(CO2)pneumoperitoneum pressure of 10-12 mm Hg(Group A,n=9)or 13-15 mm Hg(Group B,n=6).Renal function and urinary volume(UV)of Group A showed no remarkable change following the operation.But in Group B,the levels of blood urine nitrogen(BUN)and serum creatine(Scr)were increased significantly,and creatinine clearance rate(Ccr)and UV were remarkably decreased(P＜0.05).These variants gradually retumed tO the preoperative levels after 1 week.The analysis showed that laparoscopic choleeystectomy at CO2 pneumoperitoneum pressure of 10-12 mm Hg in CRF patients might be safe.Higher CO2 pneumoperitoneum pressure could result in reversible renal Email:yuanhuizhong2000@yahoo.com.cnfunction change.
