Comparison of post Operative analgesia with intraoperative administration of bupivacaine localy and intrersphincteric in hemorrhoidectomy operation

Comparison of analgesia after hemorrhoidectomy using local and intrasphincteric injection of bupivacaine

This is a double-blind clinical trial study with parallel groups that is performed by simple randomization method with the help of STATA software on 60 patients referred for hemorrhoidectomy.

All patients referred to hospitals and private clinics for hemorrhoidectomy who met the inclusion and exclusion criteria were included in the study. After performing a similar anesthesia procedure, one group underwent local injection and the other group underwent intrasphincteric injection in 4 positions (12, 3, 6, and 9 o'clock). Finally, hemorrhoidectomy is performed. Finally, 6 and 12 hours after Patients' full recovery, the patient's need for analgesia, and pain intensity are assessed and compared using a Visual Analogue Scale for Pain that will be used for both groups. The patient and the person evaluating the pain are blind to the type of intervention.

Inclusion criteria were people between the ages of 20 and 70 and those who were in Class I and II according to the ASA (anesthesia class) criteria, and the non-inclusion criteria were those who were in Class III and IV according to the ASA criteria. People with a history of drug addiction, people with a history of any heart, liver, kidney or neurological disease, or allergies to any medication, and inability to determine the use of a verbal scale.

In patients referred for hemorrhoidectomy, bupivacaine injection is performed to reduce postoperative pain at the operation site by two methods, local and intrasphincteric, and finally Postoperative analgesia is compared.

Evaluation patients' pain after surgery

In this study, simple randomization is used and the unit is individual randomization. In this way, with the help of STATA software, random codes are assigned to each patient in both intervention groups about the injection method and are recorded on a questionnaire, and the patient and the questioner are blind to avoid bias towards those codes.

After obtaining the patient's informed consent, surgery is performed and the patient does not know about his anesthesia method during the operation. Also, after the operation and the patient entering the ward, the questioner does not know about the injection method and only completes the pain questionnaire.
