Effects of sequential nursing care on patient-ventilator interaction after cardiovascular surgical procedure

Abstract

Objective To explore the effects of sequential nursing care on patient- ventilator inter-action after cardiovascular surgical procedure. Methods thirty-six patients after cardiovascular surgical procedure in ICU from July 2006 to July 2007 were enrolled, they were randomly divided into the experi-mental group and the control group with 18 patients in each group.The experimental group adopted sequen-tial nursing care, while the control group received conventional nursing care. The condition of patient- venti-lator interaction after cardiovascular surgical procedure was observed and underwent t test. Results Gen-erally, there were significant differences in inspiratory trigger pressure(P-T), inspiratory delay time(D-I), inspiratory trigger time (D-T). The index of arterial blood gas at 4,8,12 hours after patients regain con-sciousness completely was better and the time of mechanical ventilation after operation,the time of ward-ship,the hospi-tal stay time were also significantly shorter in the experimental group than those in the con-trol group. Conclusions The patient-ventilator counteraction can be reduced,and the patient-ventilator synchreny can be alleviated by sequential nursing care.
