Abstract:
Conventional spinal anesthesia has many complications like hypotension, bradycardia, urinary retention, post-dural puncture headache (PDPH), transient or permanent neurological symptoms. These complications can be minimized by performing unilateral spinal anesthesia in patients requiring one sided lower limb surgeries. Low anesthetic doses, pencil point or cutting point needles, slow injection rate and the lateral position help in achieving unilateral spinal anesthesia. This prospective study aimed at investigating the effects of unilateral spinal anesthesia with low dose (5 mg) hypobaric bupivacaine minimizing hemodynamic changes, limiting the cephalad dispersion of the anesthetic and promoting a faster recovery.Keywords:
