Journal of Medical Postgraduates 2003;0(12):-
Objective: To observe the clinical effects of combination of propofol,fentanyl and in surgical abortion. Methods: A total of 184 early-pregnant women were randomly divided into two groups.The women in group Ⅰ received propofol 2.5 mg/kg intravenously(n=92),the women in group Ⅱ received the combination of propofol,fentanyl and atropine intravenously(fentanyl 1 ?g/kg,atropine 0.5 mg,propofol 1 mg/kg)(n=92).To compare the efficacy of those two kinds of anesthesia,many measurements were taken, which included the total dose of propofol applied,induction time,recovery time,self-walking time,operative time,blood loss during the abortion,dilatation of the uterine cervix,blood pressure,heart rate,breathe,pain caused by injection and post-operation uterine contraction. Results: Many differences were found in the group who received the combination of propofol with fentanyl and atropine,when compared to those measurements in the group received propofol only.Significantly less(amount) of propofol was needed.The induction time was significantly shorter.The slowing of heart rate,dropping of blood pressure and reduction of breathing were significantly less.The dilation of the uterine cervix was more complete and took much less time.The pain caused by injection and post-operation contraction was significantly less frequent and less severe. Conclusion: Applying the combination of propofol,fentanyl and atropine has several clinical benefits which include less propofol need,less inhibition to the respiration and cardiovascular system,and less pain caused by injection and post-operation contraction.

Objective To estimate the frequency of heart valvular involvement in Chinese patients with Takayasu arteritis (TAK) and its correlation with other clinical features. Methods Ninety-one patients with TAK were studied and their clinical manifestations, laboratory test, vascular images and echocardio - gra-phic findings were retrospectively reviewed. The data were compared between patients who had heart valvular involvement and those who had not. Mann-Whitney U-test or Student's t-test, Chi-squared test or Fisher's exact test were used for analysis. Results Aortic regurgitation and mitral regurgitation were both confirmed in 20 (22%) patients. Tricuspid regurgitation and pulmonary valve regurgitation were observed in 10 (11%) and 2 (2%) patients, respectively. Older age at onset, longer disease duration, hypertension and involvement of the ascending aorta were all significantly more frequent in TAK patients with aortic regurgitation (t=2.903, P<0.01; Z=-2.759, P<0.01; χ2=7.918, P<0.01; Z=-4.454, P<0.01) than those without. However, the constitutional symptoms and acute phase reactants [erythrocyte sedimentation rate (ESR) and C reactive protein (CRP)] were not statistically different between patients with and without valvular regurgitation (P>0.05). Aortic valvular pathology examination of the three TAK patients who had underwent aortic valve replacement showed no inflammatory cell infiltration. Conclusion This study has demonstrated that heart valve involvement is common in patients with TAK, mainly in the form of regurgitation, and which may be secondary to hypertension and other cardiovascular complications. We should pay more attention to the screening and treatment of heart valvular involvement in TAK patients.
