ABSTRACT

Objective 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 groupscontrol 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
