Comparative Study of the Analgesic Effect of Subarachnoid or Infiltration for Hemorrhoidectomy
Description:
This is a prospective, randomized study, including 40 patients between 18 and 60 years, of
both genders, ASA 1 or 2.
Patients in group 1 (n = 20) will be submitted to spinal block and group 2 (n = 20) to
infiltration. The spinal block will be performed with 10 mg of 0.5% bupivacaine. The
infiltration will be performed with 10 ml of 0.5% bupivacaine with epinephrine on each side.
Will be evaluated: intensity of pain on a numerical scale from 0 to 10 every 15 minutes,
relaxation of the sphincter muscles, intensity of pain after the operation every 30 minutes
until reached the criteria for discharge, muscle strength of the lower limbs every 30
minutes, BP, HR, SO2, FR, other items that determine the conditions of discharge (urine
output, nausea and vomiting), time to hospital discharge, and duration of analgesia. Adverse
effects and complications will be noted.
