Summary
Caruncular sub-Tenon single injection provides effective local anesthesia for eye surgery, offering an alternative to peribulbar anesthesia with a low complication rate. This technique ensures good surgical conditions and patient comfort.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Retrobulbar injection complications led to peribulbar anesthesia adoption.
- Peribulbar anesthesia often requires supplemental injections due to imperfect blockade.
- Caruncular sub-Tenon single injection is presented as an alternative local anesthesia technique.
Purpose of the Study:
- To evaluate the efficacy and safety of caruncular sub-Tenon single injection for local anesthesia in ophthalmic surgery.
- To compare this technique with traditional peribulbar anesthesia.
Main Methods:
- Prospective study involving 183 eyes.
- Regional anesthesia administered via a single caruncular sub-Tenon injection.
- Evaluation of akinesia, analgesia, pain, supplemental injections, eyeball orientation, and surgical conditions.
Main Results:
- Total motor blockade achieved in 85.8% of cases; total lid akinesia in 96.2%.
- Only 4.4% of patients required a second injection; 5.5% experienced pain during surgery.
- Good or very good surgical conditions in 90% of cases, with no injection-related complications.
Conclusions:
- Single-injection caruncular sub-Tenon anesthesia is a viable alternative to peribulbar anesthesia.
- The technique is efficient, simple, easy to learn, reproducible, and associated with a low complication rate.
