Abstract: : Purpose: The aim of this study was to investigate the effects of administration of IV fentanyl before the retrobulbar block on pain scoring and hemodynamic stabilite during cataract surgery. Methods:120 patients underwent phacoemulsification prosedure. The age of patients changed 40- 78 years old. First group received retrobulbar block without fentanyl IV. Second group received retrobulbar block with fentanyl IV. Fentanyl 2mcg / kg IV was administered 5 minutes before the retrobulbar block. The patients were evaluated with verbal pain scores (0= no pain 1= mild pain 2= moderate pain 3= severe pain). All patients were premedicated with 3mg midazolam(IV) and monitored with anesthesia machine (Cicero EM ). Systemic blood pressure,heart rate, SpO2 were recorded with one minute intervals. Results: Increasing of systemic blood pressure and heart rate during the retrobulbar block indicates the hemodynamic responses due to pain. While significant hemodynamic changes were observed during retrobulbar block in first group, hemodynamic parameters in second group remained stabile. The verbal pain scores in group II were found lower than group I . Difference between two groups was statistically significant (p< 0.05). Conclusion: All the patients to be operated with local anesthesia may be given fentanyl analgesia for decreasing pain and possible systemic hemodynamic changes due to stress and pain during retrobulbar block in cataract surgery.
