Summary
Supplemental intraoperative local anesthesia using a 19-gauge irrigating cannula effectively manages pain during prolonged retinal detachment surgery. This safe technique ensures minimal patient discomfort throughout lengthy vitreoretinal procedures.
Area of Science:
- Ophthalmology
- Surgical Anesthesia
Background:
- Local anesthesia from retrobulbar injections can diminish during extended retinal surgeries.
- Maintaining adequate anesthesia is crucial for patient comfort and surgical success in prolonged procedures.
Purpose of the Study:
- To describe a simple, safe, and effective technique for supplemental intraoperative local anesthesia during retinal detachment surgery.
- To evaluate the efficacy of this technique in managing patient discomfort during prolonged vitreoretinal procedures.
Main Methods:
- A 19-gauge irrigating cannula is used to administer supplemental local anesthesia.
- The cannula is passed posterior to the globe after a limbal peritomy and quadrant dissection.
- 4% lidocaine hydrochloride is used to irrigate the recti muscles and retrobulbar space.
Main Results:
- The described technique provides effective supplemental intraoperative local anesthesia.
- Prolonged vitreoretinal surgery can be performed with minimal patient discomfort.
- The method is simple, safe, and easy to administer.
Conclusions:
- This technique offers a reliable solution for anesthesia management in extended retinal detachment surgeries.
- It allows for the completion of complex vitreoretinal procedures under local anesthesia with improved patient experience.
