Incidence and severity of postoperative pain
Zeitfenster: From enrollment to the end of treatment at 3 days
|
Using an 11-point Numeric Rating Scale (NRS) where the endpoints are the extremes of no pain and worst pain.
Pain intensity was assigned into one of four pain categories: none (0); Mild (1-3); Moderate (4-6) and severe (7-10).
Postoperative pain levels will be documented by the patients at 6, 12, 24, 48 and 72 hours postoperatively

In case of severe or persistent postoperative pain, the operator will permit the patient to take Ibuprofen (200 mg) not more than 6 hours apart.
Patients will be instructed to record their analgesic consumption by counting the number of tablets taken in the course of 72 hours postoperatively.
