p-value: p=<0.0001
The study found a high incidence (11.7%) of failed spinal anaesthesia during Caesarean section in a South African hospital, highlighting the need for upskilling doctors.
Alabi et al. (2017) conducted a cross-sectional in Pregnant women scheduled for Caesarean section (n=197). Obesity vs. Non-obese was evaluated on Failed spinal anaesthesia (RR 13.7, 95% CI 5.4-34.7, p=<0.0001). Obesity was associated with a significantly higher risk of failed spinal anaesthesia during Caesarean section compared to non-obese patients (RR 13.7).
