Insights
Anesthesia management for strabismus surgery can reduce oculocardiac reflex and postoperative nausea. Ketamine or midazolam induction and combination anti-emetics are recommended for pediatric patients.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Ophthalmology
Context:
- Strabismus surgery is a common pediatric procedure requiring careful anesthetic management.
- Patients may have comorbidities like congenital heart disease or neuromuscular disorders.
- High incidences of oculocardiac reflex (OCR) and postoperative nausea and vomiting (PONV) are concerns.
Purpose:
- To review anesthetic strategies for minimizing OCR and PONV in pediatric strabismus surgery.
- To evaluate the efficacy of different anesthetic agents and anti-emetic therapies.
- To assess the benefit of combined general anesthesia and peribulbar block.
Summary:
- Ketamine or midazolam induction reduces OCR risk, while propofol/remifentanil increase it.
- Combination anti-emetic therapy (e.g., ondansetron and dexamethasone) reduces PONV risk by at least 10%.
- Peribulbar block in addition to general anesthesia significantly decreases both OCR and PONV incidence.
Impact:
- Optimized anesthetic protocols can improve patient safety and outcomes in pediatric strabismus surgery.
- Evidence-based recommendations for managing OCR and PONV can guide clinical practice.
- Reduced complications may lead to shorter hospital stays and improved patient satisfaction.
Abstract:
Strabismus surgery is one of the most common paediatric operation procedures. As associated with congenital syndrome, congenital heart disease and neuromuscular disorder, the anesthesiologic management has to be planned carefully. Considering high incidences of oculocardiac reflex (OCR) and postoperative nausea and vomiting (PONV) anesthesia can be performed to decrease both. Induction of anesthesia with ketamine or midzolam reduces risk of oculocardiac reflex, whereas propofol or remifentanil lead to higher incidences of OCR. A combination anti-emetic therapy from different drug classes is recommend to patients at high risk for nausea and vomiting like patients undergoing strabismus surgery. A combination therapy of ondansetron and dexamethasone lead to a risk reduction of PONV to at least 10 %. Further, the incidence of OCR and PONV is significantly reduced in children receiving peribulbar block on top of general anaesthesia.
