Summary
Adding adrenaline to retrobulbar anesthesia for cataract surgery reduced intraocular pressure and prolonged pain relief. This enhancement improved surgical conditions and patient recovery, benefiting extracapsular cataract extraction outcomes.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Senile cataract is a leading cause of vision impairment.
- Extracapsular cataract extraction is a common surgical procedure.
- Retrobulbar anesthesia is frequently used for ocular surgeries.
Purpose of the Study:
- To evaluate the effect of adrenaline in retrobulbar anesthesia for extracapsular cataract extraction.
- To assess the impact on intraocular pressure, surgical conditions, and postoperative pain.
Main Methods:
- Seventy-five patients undergoing extracapsular cataract extraction were randomized into two groups.
- One group received retrobulbar anesthesia with adrenaline, the other without.
- Intraocular pressure, time for bulbar massage, anterior chamber depth, and analgesia duration were measured.
Main Results:
- Adrenaline group showed significantly lower intraocular pressure post-injection (p < 0.02).
- Reduced digital bulbar massage time was observed in the adrenaline group (p < 0.01).
- Postoperative analgesia duration was significantly prolonged with adrenaline.
Conclusions:
- Adrenaline in retrobulbar anesthesia offers benefits for extracapsular cataract extraction.
- It helps manage intraocular pressure and enhances postoperative pain control.
- Further research into the mechanisms of adrenaline's effects is warranted.
