Objective To determine the value of multimodal analgesia used to reduce the degree of postoperative cognitive dysfunction (POCD) in the aged patients undergoing total hip-replacement surgery.Methods Fifty ASA Ⅱ-Ⅲ patients aged 60-79 years old,undergoing total hip-replacement surgery were divided randomly into trial group and control group,each group 25 patients.The visual analogue scale (VAS) and the usage amount of sufentanil were recorded after operation.The mini-mental state examination (MMSE) was used to assess the cognitive function before operation and after operation.Results The VAS scores after operation for 3 d in two groups was significantly lower than that after operation for 1 d (P ＜ 0.05),the VAS scores after operation for 1,2 d in trial group was significantly lower than that in control group (P ＜ 0.05).The usage amount of sufentanil at every time in trial group was also lower than that in control group (P ＜0.05).The MMSE scores before operation and after operation for 3 d in two groups had no significant difference (P ＞ 0.05).The MMSE scores after operation for 1,2 d in trial group was significantly higher than that in control group (P ＜ 0.05).The MMSE scores after operation for 1,2 d in two groups was significantly lower than that before operation (P ＜ 0.05).Severe POCD of both groups was not occurred.Conclusion Multimodal analgesia may reduce early postoperative cognitive dysfunction of the aged patients undergoing total hip-arthroplasty via general anesthesia.

Objective: The expression of eNOS and iNOS in lung tissues plays an important role in lung injury after cardiopulmonary bypass. The aim of this study is to evaluate the effect of pulmonary artery perfusion with hypothermic solution on eNOS and iNOS expression in lung tissue during CPB. Methods: 34 young children with congenital heart disease and pulmonary hypertension were divided into the control group (n=23) and protective group (n=11). The basic parameters (age, weight, data of catheterization and other assistant examination) were similar. In the control group, operation were performed using routine techniques, and in the protective group, pulmonary artery was infused with 4℃ protective solution during CPB. Immunohistochemical analysis was performed on 4-?m paraffin sections of lung tissue at end of CPB. The distribution and expression of eNOS and iNOS in pulmonary endothelium, bronchi epithelium and macrophages were studied using the immunohistochemical technique. Results: The strong iNOS-expression was showed in pulmonary endothelium (2.24?0.60) and lower iNOS-expression in bronchia epithelium (0.88?0.60) and alveolar macrophages (10.6?4.0) in protective group and lower eNOS-expression in endothelia and over iNOS-expression in alveolar macrophages and bronchia epithelia in the control group (P

Objective To observe the protective effect of acceleration neutruphils apoptosis on lung injury after cardiopulmonary bypass(CPB) . Methods The neutrophils were separated using discontinuous Percoll gradients in vitro and cultured for 48 hours with or without clarithromycin. Neutrophil survival was determined by typan blue dye exclusion method. Apoptotic neutrophils were detected with flow cytometry. Immune histochemistry was used to examine the expression of protein of Fas and bcl-2 which interrelated with neutrophil apoptosis. In vivo study twelve adult sheeps were randomly divided into two groups. Pulmonary artery was clamped after CPB was established and the lungs were perfused with 4℃ low molecular weight dextran solution in control group (n = 6) and 4℃ low molecular weight dextran solution with clarithromycin in protective group (n - 6), The bypass was withdrawn after 90 minutes. Respiratory function were recorded during CPB and cytokines in the lung were measured. Lung biopsies and the apoptosis of the neutrophil were also performed after operation. Results Clarithromycin significantly shortened neutrophil survival in a dose-dependent fashion. The result of flow cytometry showed that the apoptosis rates at 24h of clarithromycin group were (33.7?4.9)%, (48.0?4.9)%, (52.0?5.4)% and (53.0?7.1)% at 1, 5, 10 and 20 ?g/ml of clarithromycin respectively while the rate in control group was (31.5?3.5)% (P

Objective This study was designed to investigate the relationship of the coronary anatomy pattern in 56 arterial switch operation (ASO) with the early outcome.Methods From May 2010 to September 2013,a total of 56 patients with transposition of the great arteries complicated with other defomities(39 males and 17 females,with age of 5 days to 126 months),who were undertook ASO in Capital Medical University affiliated Beijing Anzhen Hospital.There were 19 patients with complete transposition of the great arteries and intact ventricular septum,35 patients with complete transposition of the great arteries and ventricular septal defect.and 1 patient with double outlet right ventricle with subpulmonary ventricular septal defect (Taussing-Bing).33 were complicated with atrial septal defect and 26 with patent ductus arteriosus,20 had severe pulmonary hypertension,2 had pumonic valve stenosis and 1 had coarctatioin of aorta.All patients undertook ASO,coronay distribution were detected during the procedure and coronary artery were grafed.Results Coronary artery:Yacoub type A were 46 cases:4 patients died during the 30 days after the operation,Yacoub type B were 5 cases:2 patients died.Yacoub type C were 2 cases:1 died of low cardiac output on the operating day.Yacoub type D were 1 case and Yacoub type E were 2 cases:none of them died.Conclusion Patients with common coronary variants have undergone ASO without added mortality rate.Those with intramural or single coronary arteries have significant added mortality rate.

Objective To review the surgical results of 28 cases of endecardial cushion defect combined with double-ori-rice mitral valve. Methods Of 860 consecutive patients with endocardial cushion defect, double-orifice mitral valve was iden-tiffed in 28 patients (3.26% ) form October 1996 to November 2007. Intracardiac deformities were corrected simultaneously during the operation. Preoperative mitral valve function, surgical procedures and incidence of pestoperative mitral valve dys-function were reviewed and compared between patients with total endecardial cushion defect ( group Ⅰ, n = 11 ) and partial en-docardial cushion defect ( group Ⅱ, n = 17). Results There were 4 operative deaths in group Ⅰ caused by severe pulmonary inflammation in 3 cases and low cardiac output in 1 case. Two cases were identified as severe mitral valve dysfunction or steao-sis in reoperaticu or autopsy. There was no later death. Mitral valve function is not eatisfactory in group Ⅱ as compared with group Ⅰ in 3 to 89 months of follow-up( averaging 33 months). Conclusion Double-orifice mitral valve is a high risk factor for operative death in total endocardial cushion defect and the longer term results of partial endocardial cushion defect combined with double-orifice mitral valve is not satisfactory.
