Purpose Of The Study:
To study the use of partogram in the analysis of spontaneous labour at term in primigravida with cephalic presentation.
Methodology:
Partographic analysis of labour was done in 200 primigravidae. Partographic variables are plotted, and the study population was divided into three groups. Group I: Cervix dilatation and descent curve falling to the left of alert line; Group II: Cervix dilatation and descent curve falling to the right of alert line; and Group III: Cervix dilatation and descent curve falling to the right of action line. Maternal and neonatal outcomes were studied in each of three groups.
Results:
Amongst the 200 primigravid labours analysed, 133 (66.5 %) belonged to group I, 40 (20.0 %) belonged to group II and 27 (13.5 %) belonged to group III. Mean durations of active phases of labour were 4.1 h, 6.9 h and 9.6 h, in groups I, II and III, respectively. In group I, 130 women (97.7 %) delivered vaginally, 3 (2.3 %) underwent LSCS. In group II, 29 (72.5 %) delivered vaginally, 4 (10 %) delivered instrumentally and 7 (17.5 %) underwent LSCS, and in group III, 5 (18.5 %) delivered vaginally, 7 (25.9 %) delivered instrumentally and 15 (55.5 %) delivered by LSCS.
Conclusion:
Mean duration of active phase of labour increased as the partographic curve fell to the right of alert and action line. Increased rates of instrumental deliveries, LSCS, babies with lower APGAR score at 5 min, and NICU admissions were observed in group III compared with groups I and II.
