Comparative Study of Invasive Blood Pressure Measurement of Lateral Position and Supine Position

Objective:To investigate whether invasive boold pressure measurement of lateral position and supine position was different or not.Methods:Boold pressure measurement of supine position,right lateral position and left lateral position was measured in 30 patients,with invasive boold pressure monitoring by the femoral arteries of right under limbs.Results:The mean systolic pressure of supine position was 135.63±21.47 mmHg,that of right lateral position was 133.67±26.18 mmHg.There was no significant difference in the two groups,P0.05.The mean systolic pressure of left lateral position was 123.33±26.67mmHg,which was significant difference with that of supine position,P0.05.The mean diastolic pressure of supine position was 76.23±13.94mmHg,that of right lateral position was 76.16±13.04mmHg,There was no significant difference in the two groups,P0.05.the mean diastolic pressure of left lateral position was 65.80±12.89mmHg,which was significant difference with that of supine position,P0.01.Conclusion:When the right femoral arteries were used for invasive boold pressure monitoring of different positions,there was no significant difference between right lateral position and supine position.The mean systolic pressure of left lateral position was 12.30mmHg lower than that of supine,and the mean diastolic pressure was 10.43mmHg lower.
