Ischiadicus nerve block with parasacral approach is an anesthetic option for surgery in the lower extremity. This method offers many advantages such as high rate of successful block and less use of local anesthetic agent. The purpose of this study was to compare the onset and duration of action of ischiadicus nerve block with parasacral approach assisted by a nerve stimulator using 20 mL of 0.5% bupivacaine to 30 mL of 0.5% bupivacaine in Dr. Hasan Sadikin General Hospital Bandung and Dr. Slamet Hospital Garut between the period of October to November 2015. This experimental randomized controlled study was performed on 36 adult patients undergoing lower extremity surgeries. Patients were divided randomly into two groups consisting of 18 patients. Group A was given 20 mL of 0.5% bupivacaine while group B was given 30 mL of 0.5% bupivacaine. The onset and duration of action of sensory and motoric blocks were recorded. The t-test and Mann Whitney test used in this study showed that the duration of sensory and motoric blocks in group A was significantly shorter than that of group B (p<0.05). It is concluded that the ischiadicus nerve block with parasacral approach using 20 mL of 0.5% bupivacaine has the same onset but shorter duration of sensory and motoric blocks compared to 30 mL of 0.5% bupivacaine.
