Background: A variety of systemic and intrathecal adjuvants to local anesthetics have been found to expand the duration and improve the quality of spinal block and decrease pain after surgeries. Objectives: The aim of this study was to evaluate the effect of the addition of midazolam to lidocaine for spinal anesthesia in lower abdomen and lower limb surgeries. Results: The motor block duration in midazolam and control group was 82.9 ± 27.3 and 59.1 ± 26.5, respectively (P = 0.01). However the duration of sensory block was not different between the two groups (P = 0.07). The median of sensory block level was at T8 and T10 in midazolam and control group (P = 0.02). Recovery time was more prolonged in the midazolam group (P = 0.002). Hemodynamic indices did not show any significant differences between the two groups. Conclusions: Addition of 30 μg/kg midazolam to lidocaine for spinal anesthesia improved duration of motor block and increased intraoperative sedation score without causing side effects in patients’ requiring lower abdomen and lower limb surgery.
