Obstetrical Outcomes in Primigravida with Engaged Versus Unengaged Fetal Head during Spontaneous Labor

When the fetal head's widest diameter fits into the pelvic inlet, it is referred to as engaged. When a primigravida's labor begins with the fetal head still not engaged, she was most likely to experience an obstructed labor. This study was conducted at a large tertiary care center with adequate sample size to determine the study outcomes. Objective: To compare the obstetrical outcomes in primigravida with engaged versus unengaged fetal head at the onset of spontaneous labor in terms of delivery methods and associated risks. Methods: This was a case control study. Study was conducted at Department of Obstetrics and Gynecology National Hospital Defence, Lahore. One hundred thirty patients through non-probability consecutive sampling. Demographic data like name, age was recorded for participants. Data were analyzed using SPSS version 22.0. RR was calculated for two groups. Results: Mean age of patients was 22.4 ± 2.6 years. Total 44.7% patients had C-section. When comparison of engaged and unengaged fetal head, 49 patients out of 88 i.e. 55.68% patients had engagement of head in vaginal delivery group and 16 patients out of 42 i.e. 38% patients had engagement of fetal head in C-section group. Relative risk among two group was 1.2564 and z score was 1.847 and p value was 0.0648. Conclusion: Relative risk of primigravida getting C-section was high with un- engaged fetal head compared to primigravida who has engaged fetal head
