Abstract: To evaluate the effects of patient controlled analgesia（PCEA）on the perioperative changes of circulatory and pulmonary function of elderly with hypertensions after abdominal surgery. Methods Twenty-eight patients of ASAⅡ-Ⅲ aged more than 60 years undergoing uratomy were randomly divided into two groups: control group and PCEA group.Preoperative and postoperative circulatory and pulmonary functions were measured with noninvasion circulatory monitor and pocket lung function meter respectively.Results In control group，the systolic pressure，diastolic pressure，and heart rate increased by 19%,17% and 19%,respectively, as compared with preoperation.The percentage of forced vital capacity (FVC%),percentage of forced expiratory volume in first second to forced vital capacity(FEV1%) and percentage of maximal ventilatory volume (MVV%) of postoperation in control group were significantly decreased compared with preoperation （P<0.05）.Whereas,in PCEA group，the blood pressure，heart rate，and pulmonary parameter had no significant change between preoperation and postoperation,but the blood pressure and heart rate were significantly lower than those in control group(P<0.05).In PCEA group,except MVV%,the other pulmonary parameters had no obviously change as compared with preoperation,but they were all better than those in control group(P<0.05). Conclusion Postoperation PCEA can provide a better analgesic effect and improve the function of circulatory and respiratory system,and also reduce the risk of the operation.
