This umbrella review evaluated pharmacological strategies for induction of general anaesthesia in caesarean deliveries, analyzing data from various studies. It found moderate quality evidence that short-acting opioids improve maternal haemodynamics without harming neonates. Propofol was preferred over thiopental for its safety profile, while rocuronium was comparable to suxamethonium regarding intubation conditions and neonatal outcomes.
Key findings
- Short-acting opioids provided maternal haemodynamic benefits without negative neonatal consequences.
- Propofol reduced the risk of maternal awareness compared to thiopental with equivalent neonatal resuscitation needs.
- Labetalol, dexmedetomidine, lidocaine, and remifentanil effectively attenuated maternal haemodynamic responses with minimal neonatal effects.
- Rocuronium at ≥ 1 mg.kg -1 offered comparable intubation conditions to suxamethonium without affecting neonatal outcomes.
Why it matters
Understanding the safest and most effective pharmacological strategies for general anaesthesia in caesarean deliveries is crucial for optimizing maternal and neonatal outcomes. This review provides evidence-based guidance for clinicians in selecting appropriate induction agents.
What to keep in mind
The evidence base is limited by the exclusion of high-risk pregnancies and emergency cases, affecting generalizability.
