Is this trial a fit for you?

Likely a good fit

Ideal candidates are singleton pregnancies at 37-42 weeks with ASA II status, aged 18-35, scheduled for elective cesarean delivery, and able to provide informed consent.

Probably not a fit

Patients with contraindications to neuraxial anesthesia, significant comorbidities, or factors preventing protocol completion may not experience a hearing-related benefit.

What this trial studies

This is a single-center, prospective, single-blind randomized trial enrolling 144 pregnant women undergoing elective cesarean delivery. Participants are randomized to receive either combined spinal-epidural anesthesia or general anesthesia. Neonatal hearing is screened with transient evoked otoacoustic emissions (TEOAE) and followed up at 3-6 months if initial screening is failed; additional data include maternal hemodynamics, time from anesthesia start to delivery, Apgar scores, and maternal pain scores. Outcome assessors are blinded to group assignment to reduce bias. The study uses sealed allocation and independent statistical planning to ensure proper randomization.

Why it matters

Potential benefit: If successful, the findings could guide anesthesia choices to optimize neonatal hearing outcomes after cesarean delivery.

How similar studies have gone: Similar investigations have explored maternal anesthesia effects on neonatal outcomes, but direct evidence on hearing with these techniques remains limited.
