🔍 Key Findings
- Neonatal survival to discharge was 93.1% overall, with no significant difference between brachycephalic (94.8%) and nonbrachycephalic (91.8%) breeds.
- Elective C-section significantly improved neonatal survival (99.2%) compared to emergency C-section (87.1%) (p < .001).
- Larger C-section litter size was positively associated with survival (p = .004; OR 1.57), whereas total litter size had no effect.
- Maternal heart rate and stage of labor were associated with neonatal mortality in univariable analysis, but not multivariable.
- Brachycephalism alone was not a risk factor for neonatal mortality (p = .221) in multivariable analysis.
- Emergency C-section was the strongest predictor of neonatal mortality (OR 4.75), regardless of breed.
- Multidisciplinary team approach likely contributed to high survival rates, emphasizing importance of coordinated care.
- Historical factors such as primiparity and maternal age were not associated with mortality in this cohort.
