Should a different Partogram be used for the Trial of Labour in Women with the Previous One Caesarean Section Scar as Compared to Primiparous Women; A Comparative study.

Objective: To compare various labour parameters in partogram among primiparous women and women with one previous caesarean section scar Study Design: Comparative cross-sectional study Place and Duration of Study: Gynaecology and Obstetrics Department, Pak Emirates Military Hospital, Rawalpindi Pakistan, from Oct 2021 to Sep 2022. Methodology: This study was conducted on primiparous women and women with one previous scar who were booked cases in our department for antenatal checkups and labour. Patients were divided into two groups for comparison. Group-I were primiparous, while Group-II had one previous scar. All women underwent detailed labour records via conventional partogram in the labour room. Duration of the active phase of labour, duration of the second stage, time to progress by 1 cm and time after the alert line were compared in partograms of both the study groups. Results: A total of 390 women who were either primiparous or had one previous caesarean section were recruited for this study. Of the study participants, 226(42.6%) were primiparous, while 164(57.4%) had one previous caesarean section scar. Statistical analysis revealed that the duration of the active phase of labour, time to progress by 1 cm and time after the al ert line were statistically significant (p-value<0.05) in partograms of women in Group-I (primiparous) as compared to those in Group-II (women with one previous scar) (p-value<0.05). Conclusion: The main parameters of the partogram differ significantly among primiparous women and women with one previous caesarean section scar. [ABSTRACT FROM AUTHOR]
