Abstract:
Objective To explore the changes on the value of CVP with different body postures after upper abdominal surgery in order to provide accurate basis for better monitoring of central venous pressure(CVP). Methods The CVP, blood pressure,pulse,respiration of 43 patients after upper abdom-inal surgery with indwelling central venous catheter were measured under supine position, 15°dorsal ele-vated position and 30°dorsal elevated position.The data were collected for correlation and regression analysis. Results The CVP value increased with the elevation of body postures,the CVP value under supine position was linearly positively correlated with the other two positions(P<0.01).The regression e-quation of supine position and 15°dorsal elevated position was:Y=1.009X1+0.811; the regression equation of supine position and 30°dorsal elevated position was:Y=1.005X2+1.630. Conclusions Through moni-toring the CVP value under 15°dorsal elevated position and 30°dorsal elevated position,and substitute it in equation,we can evaluate the CVP value under supine position.
