Abstract:
Objective To investigate the inter-arm invasive blood pressure differences during hip replacement in patients with lateral position and its relationship with position.Methods Sixty-six patients having underwent hip replacement in orthopedic surgery with lateral position were enrolled.Invasive blood pressure measurements were obtained from bilateral radial artery in all patients every 5 minutes.Simultaneously bilateral invasive blood pressure measurements were obtained and compared.Results At supine position,systolic pressure,diastolic pressure and mean arterial pressure of the uninjured side were (128.16 ±20.09),(69.47 ± 8.64) and (89.03 ± 10.42) mmHg (1 mmHg =0.133 kPa);systolic pressure,diastolic pressure and mean arterial pressure of the injured side were (127.90 ± 20.44),(69.86 ± 8.81) and (89.21 ± 10.71) mmHg.There was statistical difference in inter-arm diastolic pressure (P ＜ 0.05),but inter-arm systolic pressure and mean arterial pressure had no statistical differences (P ＞ 0.05).At left-lateral position,systolic pressure,diastolic pressure and mean arterial pressure of the uninjured side were (129.12 ± 21.93),(69.23 ± 8.92) and (89.19 ± 11.35) mmHg;systolic pressure,diastolic pressure and mean arterial pressure of the injured side were (129.01 ± 21.72),(69.51 ± 9.02) and (89.34 ± 11.35) mmHg.There was statistical difference in inter-arm diastolic pressure (P ＜ 0.05),but inter-arm systolic pressure and mean arterial pressure had no statistical differences (P ＞ 0.05).At right-lateral position,systolic pressure,diastolic pressure and mean arterial pressure of the uninjured side were (128.78 ± 20.34),(69.54 ± 9.06) and (89.29 ± 10.82) mmHg;systolic pressure,diastolic pressure and mean arterial pressure of the injured side were (128.27 ± 20.56),(70.00 ± 9.09) and (89.43 ± 10.89) mmHg.There were statistical differences in inter-arm systolic pressure and diastolic pressure (P ＜ 0.05),but inter-arm mean arterial pressure had no statistical difference (P ＞ 0.05).The bilateral radial artery blood pressure difference under different positions was ＜ 1 mmHg,and had no clinical practical significance.There was no correlation between blood pressure and age,sex,body mass index.Conclusion Bilateral radial artery in the same patients with invasive blood pressure has no clinical difference,and patients with lateral position operation for radial artery puncture pressure need not consider the differences of blood pressure between arms.
