The increasing global rates of caesarean deliveries are influenced by various factors, including clinical contexts, patient preferences, and maternal demographics. However, vaginal birth after caesarean (VBAC) offers significant advantages by avoiding major surgery and reducing maternal complications. It is important to carefully consider the risks of failure and complications when making decisions regarding the trial of labour after caesarean (TOLAC).
Methods:The study involved a prospective observational analysis of 60 pregnant women with a singleton pregnancy at 37 weeks or later who had previously undergone a lower-segment caesarean delivery. Inclusion criteria encompassed specific conditions related to the previous caesarean, vertex presentation, adequate maternal pelvis, and an estimated foetal weight of ≤ 3.5 kg.
Results:The results indicated that none of the participants scored between 0 and 2 on the FLAMM & GEIGER scale. Participants with a score of 3 exhibited a 100% failure rate of VBAC and underwent a caesarean section. Among those with scores of 4, 61.9% achieved successful VBAC and had a vaginal delivery. Scores 5, 6, and 7, all resulted in 100% successful VBAC and vaginal deliveries. No participant scored above 7. The difference between successful and failed VBAC was statistically significant (p < 0.001).
Conclusion:The FLAMM & GEIGER scoring system, considering various factors related to the mother and foetus, proved to be a valuable tool in predicting VBAC success.
