Introduction: Primigravida are at risk patients:.their parturition capacity have never been tested.  Unengaged head at onset of labour are considered to be at high risk for operative delivery .Objective: To study the  obstetrical outcome with reference to course of labour,mode of delivery, need for intervention and fetal outcome in primigravida with unengaged fetal head at term gestation at spontaneous onset of labour. The study was conducted in NMCH,Patna Dept. of Obs & Gynae from February 2016 to January 2017.  In this study, 100 primigravida patients with unengaged fetal head  at spontaneous onset of labour at term gestation  were included . Results: In this study majority of cases (65%) were of the age group 21–25 years. Gestational age of 48 % of women  was 37–39 weeks.40% of primigravida  had gestational age of 39–40 weeks,12% had gestational age 40–41 week.  Among 100 patients  20% had free floating head,34% had fetal head 4/5 palpable per abdominally  and in 46% head was 3/5 palpable per abdominally. LSCS done in 40% of cases,normal vaginal delivery  occurred in 46% and assisted vaginal delivery  in 14% of women.Length of 1^st   stage of labour ranged from 7 hours 50 minutes to 11hrs 35 min(mean– 9 hour 45 minutes). Duration of 2 nd   stage of labour ranged from 40 –110 min (mean 55 minutes) Augmentation of labour was needed in 72  cases. APGAR score was recorded at  1 and 5 min. At 5 minutes 76 cases had APGAR score in the range of 7–10, in 20 babies APGAR score was 4–6, and <3 APGAR score seen in 4 babies   10 babies required NICU admission.Conclusion: Primigravida at term gestation with unengaged  fetal head at spontaneous  onset of labour is not an  indication of  elective LSCS..Vaginal delivery is possible with close monitoringwith good perinatal outome.
