To determine a pain scale prescribing oral diazepam before PRK surgery.
We included patients undergoing PRK, divided into two groups: the first group was prescribed diazepam 10 mg orally 30 minutes before PRK surgery and the second group had no medication preoperatively, and pain assessment was performed using pain scales in the immediate postoperative period and 24 hours postoperatively. The pain assessment scales were visual scale, visual analog scale.
A total of 21 patients, 10 in the control group and 11 in the case group and also the recording of pain scales in the immediate postoperative period and 24 hours were included. Most patients in both groups described a slight pain in the immediately postoperative period (more patients under the effect of diazepam) and no predominance at 24 hours. All pain scales had similar results.
We found that the use of diazepam 10 mg oral administration 30 minutes before a PRK significantly decreased immediately postoperative pain compared with not using any medication preoperatively. Referred pain in the technique used in the PRK, is mild in most patients.
