NCT04288349

Brief Summary

Perineal block with the anesthesia of the pudendal nerve's terminal branches allows to perform a hemorrhoidectomy with the optimal intraoperative and postoperative analgesia The purpose of this study is to assess the effectiveness of the intraoperative use of perineal block with spinal anesthesia to reduce postoperative pain and the amount of used analgesics.

Study Arms (2)

epinephrine + ropivacaine +saline

ACTIVE COMPARATOR

1% epinephrine solution + 30 ml of 1% ropivacaine solution diluted with 20 ml of 0.9% saline for achievement a 0.75% anesthetic solution in a ratio of 1: 200 000

Procedure: perineal block with usage of one of solutionsDrug: epinephrine + ropivacaine +saline

epinephrine + saline

PLACEBO COMPARATOR

1% epinephrine solution + 50 ml of 0.9% saline in a ratio of 1: 200 000.

Procedure: perineal block with usage of one of solutionsDrug: epinephrine + saline

Interventions

Perineal block using solution of ropivocaine and epinephrine for the first group was performed. Anococcygeal ligament is infiltrated with 10 ml of the solution after the intracutaneous infiltration in 2 cm from the anus. Ten ml of the solution is injected in ischiorectal fat on each side. The needle is orienteered at the angle of 45 degrees cranially and laterally, and to the surface what allows the surgeon to anesthetize the deep branches of the pudendal nerve. In addition, 10 ml of solution is injected transdermal on the front edge of the anus with further subcutaneous infiltration on each side of the anus to provide anesthesia to the nerve branches laying more superficial. The total amount of the injected solution is 50 ml.

Masking Details
Randomization of the patients included in the study was performed before surgery. Patients were being randomly divided into two groups. All patients getting subarachnoid anesthesia. Perineal block using solution of ropivocaine and epinephrine for the first group was performed and placebo with epinephrine - for the second group. A researcher who does not participate in the surgery and does not contact with patients at all perioperative stages performs randomization and prepares a solution block. Neither the patient nor the operating surgeon and the doctors who register the results of the treatment are not informed about the anesthesia used in each case. The probability of introduction to each group is 50%. The number of patients in both groups equally and is 50 people.
