Abstract:
Objective To explore the application effect of modified disinfection posture in coronary artery bypass grafting(CABG).Methods A total of 50 patients who would undergo CABG were recruited in this study by purposive sampling method in Xuzhou Central Hospital from January 2014 to December 2015. They were divided into the control group(25 cases,conventional disinfection posture)and the observation group (25 cases,modified disinfection posture)according to the random number table. The central venous pressure (CVP),blood pressure(BP)and heart rate(HR)were monitored between two groups before and after placing disinfection position with leg-raising immediately and after restoring horizontal position immediately. The comfort of body,the convenience of operation,the time of placing position and disinfection were investigated or recorded during the process of disinfection.Results There was no statistically significant difference in the time of placing position and disinfection during surgery between two groups(P>0.05). There was also no statistically significant difference in the comfort and satisfaction degree of doctors during surgery between two groups(P>0.05). The hemodynamic variables had no significant difference in two groups before leg-raising immediately(P>0.05). After leg-raising immediately,the systolic pressure,diastolic pressure,CVP and HR in the control group [(121.313±4.116), (70.423±3.291),(8.524±0.283) mmHg,(84.193±3.682) times/min] were higher than those in the observation group [(116.323±6.242),(66.191±11.468),(7.254±0.989) mmHg,(67.524±3.193) times/min] with significant differences(t=2.013,2.316,5.913,16.205;P<0.05). After restoring horizontal position immediately,the systolic pressure,diastolic pressure,CVP and HR in the control group [(109.267±6.167),(60.766±5.233),(4.063±0.572) mmHg, (86.524±4.254) times/min] were higher than those in the observation group [(101.274±9.156),(65.352±3.254), (3.544±0.623) mmHg,(69.933±7.424) times/min] with significant differences(t=3.450,2.025,2.705,9.266;P<0.05).Conclusions The application of modified disinfection posture in patients with general anesthesia and CABG has no effect on the comfort of body,the convenience of the operation,and it will not increase the time of placing position and disinfection. The modified disinfection posture can effectively avoid the impact of conventional disinfection posture on the hemodynamic variables and can improve the quality of nursing care.
