- Background: Reports have it that serum calcium levels are lower in parturient women with uterine hypotonia. Objective: To determine the relationship between serum calcium, uterine contractility and the progress/duration of labour in parturient Nigerian Igbo women. Methodology: A cohort study of 140 consecutive consenting parturient women at NAUTH, Nnewi, involving the assessment of serum calcium levels and measurement of uterine contractility by clinical methods and tocodynamometer. Labour progress, duration and mode of delivery were also recorded. Data analysis was performed using SPSS version 21. Comparison of variables employed Pearson's Chi square test, analysis of variance (ANOVA), and Mann Whitney test, with p-value <0.05 at 95% confidence interval considered to be statistically significant. Results: The mean serum ionized calcium of the population was 1.10±0.26mmol/L. Only 1 (0.71%) participant had hypercalcaemia; 74 (52.86%) had eucalcaemia, and 65 (46.43%) had hypocalcaemia. There was no significant difference in the mean serum ionized calcium between participants with adequate uterine contractions and those with uterine hypotonia (P = 0.483). Mean serum calcium was higher among the participants with good labour progress (1.12±0.22mmol/L) compared to those with poor progress (1.06±0.32mmol/L). Participants with labour duration <3hrs had higher mean serum calcium levels (1.13±0.23mmol/L) than those ≥12 hours (0.60±0.31mmol/L). Calcium were lower for assisted vaginal delivery, (1.03±0.15mmol/L) compared to spontaneous vertex (1.12±0.29mmol/L) and caesarean (1.12±0.18mmol/L) deliveries Conclusion: This study shows that optimal serum calcium level minimizes uterine atony. There is need to explore this towards the prediction and management of labour dystocia.
