RESUMO
Objective To investigate the preemptive analgesic effect and safety of paracoxib sodium in patients under-going endoscopic submucosal dissection(ESD). Methods A total of 80 ASA I or II patients aged 35-65 years undergoing ESD under general anesthesia were randomized into two groups(n=40 each):parecoxib sodium group(group B) was received intrave-nous parecoxib sodium 40 mg (in 5 mL 0.9% sodium chloride solution) 10 min before anesthesia induction and control group (group A)was received 0.9% sodium chloride solution 5 mL instead of parecoxib sodium.At the end of operation,patients in both groups were received 5 mg of dezocine.Blood samples were analyzed for PT,TT,APTT,Fib,PLT and PAgT before induction of an-esthesia,at 30 min and 120 min after operation.Patients'Visual analogue scale(VAS),Numeric sedation scale(NSS),and ad-verse reactions were recorded at the end of the operation,2,4 and 6 h after operation. Results Compared with those before parecoxib sodium administration,the fibrinogen concentration and PAgT were significantly higher in group B at 30 min after the intravenous injection of parecoxib sodium(P<0.05),while there was no significant difference in PT,TT,APTT and platelet count between group B and group A(P>0.05).VAS at the end of operation,2,4 and 6 h after operation were lower in group B(P<0.05),and the patients were more satisfied in group B(P<0.05). Conclusion Parecoxib could temporarily enhance blood co-agulation in patients undergoing ESD and could offer safe and effective analgesia.
RESUMO
Objective To determine the relationship between early postoperative delirium (EPD) and prognosis in patients undergoing non-cardiac surgery. Methods This was a prospective cohort study consisted of 698 patients admitted to postanesthesia care unit, undergoing non-cardiac surgery under general anesthesia, between June and December 2009. The risk factors affecting prognosis were collected. All the patients were assessed for the development of delirium by experienced research staff using Confusion Assessment Method for Intensive Care Unit. The patients were divided into 2 groups according to the occurrence of EPD: EPD group and no EPD (NEPD) group. The postoperative hospital length of stay was made as a major prognostic indicator. Cox proportional hazard regression model was used to analyze the risk factors affecting prognosis. Results Of the 698 patients, 197 (28.2%) developed EPD. The postoperative hospital length of stay was prolonged in group EPD compared with group NEPD. The Cox proportional hazard regression model analysis indicated that EPD was an independent risk factor affecting prognosis. Conclusion EPD is an independent risk factor affecting prognosis in patients undergoing non-cardiac surgery.
