The aim of the study was to compare the analgesic efficacy and safety of pretreatment with oral gabapentin and its newer analog pregabalin for pain control during and after panretinal laser photocoagulation (PRP).
Patients and methods
The study included 60 eyes of 60 patients with proliferative diabetic retinopathy who were aged between 18 and 60 years and were candidates for PRP. Thirty patients (group A) received gabapentin 600 mg orally and group B received pregabalin 150 mg orally 2 h before PRP. Before sessions, all patients were instructed how to assess their pain level using the visual analog scale (VAS), and sessions were performed by the same ophthalmologist using as similar parameters as possible for each treatment plan. Blood pressure and heart rate were recorded just before, during, and immediately after each treatment session, and the VAS rates during (VAS I), 15 min after (VAS II), and 2 h after PRP session (VAS III) were collected; side effects for the study drugs were recorded for the same amount of time.
The mean age was 49.47 ± 7 years in group A and 50.33 ± 10 years in group B. The mean duration of session was 12 ± 1.8 min in group A and 11 ± 1.3 min in group B. Systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure were significantly increased during sessions compared with baseline values in group A, whereas the increase in these parameters was not significant in group B. The median VAS both during the session (VAS I) and 15 min after the session (VAS II) was significantly lower in group B compared with group A, with no significant difference in the median pain score 2 h after session (VAS III) between both groups. The incidence of sedation and dizziness was significantly lower in group A compared with group B. More frequent nausea and vomiting were observed in group A compared with group B; however, this was not statistically significant.
In patients undergoing PRP, lower degree of pain associated with a better hemodynamic response was reported in those treated with preemptive 150 mg pregabalin compared with 600 mg gabapentin, suggesting that pregabalin may be better recommended for pain control during and immediately after PRP sessions.
