 After the commencement of the anesthesia monitoring of neuromuscular transmission will be commenced. Ulnar nerve at the wrist will be stimulated in a TOF sequence 2 Hz every 12 seconds. The resultant force of contraction of the adductor pollicis will be recorded using a mechanomyograph. After obtaining a stable muscle contraction, succinylcholine will be administered. The subjects will be randomly allocated to one of five groups. Group 1 will receive 0.1 mgkg, group 2 -0.15 mgkg, group 3 -0.2 mgkg, group 4 -0.25 mgkg, group 5 -0.3 mgkg. Muscle contraction will be recorded until the force of muscle contraction returns to baseline 6-8 minutes. At this time the study will be concluded. Further conduct of the anesthetic will be at the discretion of the subjects primary anesthesiologist.
