Introduction: During spinal anesthesia, measurement of blood pressure is often obtained by an indirect method using an inflatable cuff on the upper arm. The relationship between the blood pressure measurements at the two sites in patients undergoing spinal anesthesia is unclear. This study was designed to evaluate the difference observed in systolic blood pressure (SBP) taken from the upper limb (UL) and the lower limb (LL) in patients under spinal anesthesia in lower abdomen surgery.
Methods: In this descriptive-analytic study, 62 males undergoing lower abdomen surgery were selected. The blood pressure cuff was placed on the right arm, the right leg, the left arm and the left leg, respectively. Before and then 10 and 25 minutes after spinal anesthesia, the systolic blood pressure (SBP) readings was taken by finger palpation from the 4 limbs using the manual mercury sphygmomanometer. The data were analyzed using paired t-test and ANOVA.
Results: We found that SBP reading taken from the legs before and 10 minutes after spinal anesthesia were significantly higher than arms pressures (P<0.001). The SBP in the legs in 25 minutes after spinal anesthesia showed more decline compared with the arms. There was no significant difference in SBP between upper and lower limbs in all the times.
Conclusion: The blood pressure of the lower limb was higher than the upper limb. In cases that could not be detect the blood pressure from upper limb, we can measure it from lower limb. It is recommended to take a single blood pressure reading of arm before anesthesia and then use the lower limb for evaluating the difference between the two sites.
