Objective. To investigate the potential of combined sonographic and clinical determinations to predict the mode of delivery at term. Materials and method. This observational prospective cohort study was deployed in a tertiary maternity hospital (University County Emergency Hospital Craiova). Unselected low-risk primiparous pregnant women were weekly evaluated at term for ultrasound determinations (estimated fetal weight [EFW]), head descent parameters, occiput position [OP], cervical length), Bishop score and maternal characteristics (age, height, weight). A thorough statistical analysis determined which variables were significantly correlated with the delivery mode. Results. Data from 276 term primiparous were analyzed. Head descent parameters were strongly and significantly correlated with each other, but only progression distance (PD) was correlated with the delivery mode (weeks 37, 38, 41, and the week before delivery). The week before delivery (WBD) measurements of head to perineum distance (HPD) and angle of progression (AOP) reached a close to significance p level: 0.055 and 0.07, respectively. The following variables were significantly correlated with the delivery mode: BMI in all term evaluations, along with PD measured at 37 and 38 weeks, maternal age for week 39, Bishop, EFW and OP for week 40 and BMI, EFW, and PD evaluated during the WBD. We have also provided logistic regression equations for each week that correctly forecasted the delivery mode, except for week 38. Cut-off values have been established for each significant parameter per week. The cut-off values must be read in conjunction with the AUC, which ranges from 0.55 to 0.73, depending on the variable. Conclusions. There are strong and significant correlations between the “head descent” ultrasound measurements at term. BMI is predictive regarding labor outcome throughout term evaluations. PD and BMI measured at 37-38 weeks correlate with the delivery mode and apparently can be used to forecast the delivery mode when the pregnancy reaches term. WBD measurements of EFW and PD can be used to forecast the delivery mode, perhaps within a policy addressed to pregnant women with pre-labor clinical signs. Larger studies are needed, due to the need for more and better-balanced data. [ABSTRACT FROM AUTHOR]
