ABSTRACT
Objective To summarize the effective managements of cardiopulmonary bypass (CPB) duing open heart surgery in the elderly patients by comparing with that of the non-elderly groups. Methods Pre-operative common data and the managements for 84 elderly patients during the cardiopulmonary bypass from January 1998 to June 2000 were analyzed retrospectively, and the same data of 80 non-elderly patients(40-60 years old) who underwent CABG during the same period were also randomly selected and compared. Results The elderly patients were usually combined with hypertension, diabeties, chronic kindney failure and abnormal pulmonary function. The average time for CPB and clamping time for the ascending aorta were (115.6?27.0)min and (80.4?32.2)min, respectively. The average lowest nasopharyngeal and anal temperature was (29.8?1.4)℃ and (30.7?0.8)℃, respectively, showing no significant difference comaparing with those of the non-elderly patients. There was significant difference between the two groups in the transfusion of shed blood(P
ABSTRACT
Objective To probe the curative effect of thiotepa and mitomycin C for the prevention of the relapse of pterygium after its operation.Methods One hundred and eighty-two cases with pterygium were randomly divided into two groups:one group of thiotepa(158 cases with 169 eyes)and the other group of mitomycin C (24 cases with 24 eyes) and a comparative study was conducted.Thiotepa was used through dropping on the third day after the operation(1∶2 000),while MMC was used in the same way during the operation and on the third day after the operation respectively(0.2g*L-1).Results In the group of thiotepa,the wounded skin on the cornea was repaired significantly more rapidly than that in the group of mitomycin C,and the rate of the relapse of pterygium was lower in the former group than that in the latter one.Conclusion Applying thiotepa by dropping after the excision of pterygium is a safe,simple and effective supplementary measure for the prevention of pterygium relapse and also effective for recurring cases.
