Abstract

In order to control the pain after hemorrhoidectomy and anal fistulectomy, 6 mg of mg, 5% hyperbaric tetracaine without (control, group I ) or with 0.3 mg (group II) or 0.5 mg (group III) of 0.l morphine was injected with a 22 gauge spinal needle into the subarachnoid space through L 3~4 interspace of patients in lateral poaition. About 30 minutes in Fowler sposition after injection, operation was performed in lithotomy position. All the patients who had morphine showed remarkable relief of postoperative p in for an average of 27 hours. However, the dosage (0.3 or 0.5 mg) of morphine administered did not affect the duration of pain relief. Blood pressure, pulse rate and pupil size were unchanged in all patients. Dysuria after block developed for on average of 5.6, 13,2 and 14.6 hours in group I,II and III respectively. Most of these cases required urethral catheterization. Minor complications such as nausea, vomiting, itching, fever, burning sensation and paresthesia were observed 16.7, 20 and 20% of cases in group I, II and III respectively; however, no treatment was required.
