Brief summary

The aim of this study is to evaluate the ganglion Impar block in the prevention of postoperative pain after anal surgery.

Detailed description

Postoperative analgesia using ganglion Impar block after anal surgery Introduction Ganglion Impar block may be used for treatment of chronic perineal pain (1) Aim The aim of this study is to evaluate the ganglion Impar block in the prevention of postoperative pain after anal surgery. Patients and Methods After approval of local ethical committee and patient consent, this double blinded randomized study will be done on 60 patients undergoing hemorrhoidectomy surgery in Alexandria University hospital. After standard general anesthesia with Propofol 1-2mg/kg LMA for airway management and maintenance with Isoflurane 1%. The patient will be randomized into two groups. Bupivacaine group; Ganglion Impar will be blocked using G25 Quinqe spinal needle using Bupivacaine 0.5% 10ml. Saline group; Ganglion Impar will be blocked using G25 Quinqe spinal needle using Normal Saline 10ml Postoperative VAS will be measured each 1 for the first 6 hours then at 9 and 12 hours postoperative. First request of pain medications will be measured. Results Results will be collected in tables and graphs. Appropriate statistical analysis will be done. Discussion Results of the study will be discussed compared to other studies.
