Abstract:
Objective To evaluate the accuracy of non?invasive blood pressure monitoring in bilat?eral upper and lower extremities in lateral position in patients undergoing surgical procedures. Methods Forty patients of both sexes, aged 24-64 yr, BMI 20-27 kg∕m2 , of American Society of Anesthesiologists physical statusⅠ or Ⅱ, scheduled for elective neurosurgical procedures, were included in this study. Blood pressure of bilateral upper and lower extremities was monitored and recorded using appropriate cuffs. At 5 min after induction of anesthesia ( T0 ) , 10 min after the patients were turned to lateral position ( T1 ) , 30, 60 and 90 min after start of surgery ( T2-4 ) , and 10 min after the patients were turned to supine posi?tion ( T5 ) , non?invasive blood pressure was measured, and invasive blood pressure was recorded. Results Compared with the value measured on the healthy side, systolic blood pressure ( SBP ) and diastolic blood pressure (DBP) of upper extremities on the affected side were significantly decreased at T1-4, and SBP of lower extremities on the healthy side was significantly increased at T0-5 (P<0.05). SBP of upper extremities on the healthy side was increased by (23±9) mmHg when compared with that of upper extremi?ties on the affected side, and DBP increased by (23±8) mmHg. SBP of upper extremities was increased by (34±12) mmHg when compared with that of lower extremities on the healthy side in lateral position. Com?pared with SBP and DBP of lower extremities measured on the healthy side, no significant change was found in SBP and DBP of lower extremities on the affected side at T0-5 ( P>0.05) . There was no significant differ?ence between non?invasive SBP and invasive SBP of lower extremities on the healthy side, and between non?invasive DBP and invasive DBP of lower extremities on the healthy side (P>0.05). Conclusion For the patients undergoing surgical procedures, the blood pressure of upper extremities is higher on the healthy side than on the affected side when the patients are in lateral position, and there is no significant difference in the blood pressure between bilateral lower extremities; and there is no significant difference between non?invasive blood pressure and invasive blood pressure of lower extremities on the healthy side.
