Background
Adding certain drugs to the local anesthetics (LA) in peribulbar block (PBB) increases its intensity and duration of action, so we did this research to assess the impact of fentanyl addition to the LA in PBB for vitrectomy.
Methods
Forty patients were divided into:
Results
The start of the motor block was significantly rapid in the fentanyl group. Additionally, there were notable variations in the length and intensity of the block between the two groups. The postoperative pain score was lower in the fentanyl group. While it was acceptable in the control group, the block quality was perfect in the fentanyl group. Complete patient satisfaction happens more often in the fentanyl group. There were no complications reported.
Conclusion
Fentanyl, when added to LA mixtures in PBB in vitrectomy, decreased the onset, increased the duration of lid and globe akinesia, and improved the quality of analgesia without causing any complications.
