Summary
Phacoemulsification surgery using topical or retrobulbar anesthesia resulted in a low incidence of postoperative nausea and vomiting (PONV). No significant differences in PONV were observed between the two anesthesia methods.
Area of Science:
- Ophthalmology
- Anesthesiology
- Surgical Outcomes
Background:
- Phacoemulsification is a common cataract surgery technique.
- Postoperative nausea and vomiting (PONV) can be a distressing complication.
- Local anesthesia techniques aim to minimize patient discomfort and systemic side effects.
Purpose of the Study:
- To compare the incidence of postoperative nausea and vomiting (PONV) in patients undergoing phacoemulsification.
- To evaluate the safety and efficacy of topical versus retrobulbar anesthesia for this procedure.
Main Methods:
- A prospective randomized clinical trial was conducted with 107 Chinese patients undergoing phacoemulsification.
- Patients received either topical anesthesia or retrobulbar anesthesia without sedation.
- Outcomes measured included PONV, need for antiemetics, and intraocular pressure (IOP) one day post-surgery.
Main Results:
- The overall incidence of PONV was low at 3.7%.
- No statistically significant difference in PONV was found between topical and retrobulbar anesthesia groups.
- Factors such as fasting time, surgery duration, and preoperative risk factors did not correlate with PONV incidence.
Conclusions:
- Both topical and retrobulbar anesthesia are associated with a low incidence of PONV in phacoemulsification.
- The choice between topical and retrobulbar anesthesia does not appear to significantly impact PONV rates.
- PONV incidence is not significantly correlated with surgical duration, complications, or patient-specific risk factors.
