Patients who have undergone a hemorrhoidectomy are included in the study, the pain treatment modality is conceived by the treating surgeon or anesthesiologist. The first modality is to administer pain killers on-demand depending on visual analog scales of pain and the second modality to give pain killers on determined hours.
Hemorrhoidectomy is one of the operations that causes the greatest intensity of pain. Treatment of postoperative pain is essential for the well-being of the patient. Long-term use of opioids and different drugs can have unintended consequences.~The objective is to corroborate which pain treatment modality is better in patients after hemorrhoidectomy.
