ABSTRACT
Aim: To evaluate the factors
associated with failed induction of labour and feto maternal outcome with
induction of labour.
Study Design: A cross sectional study.
Place and Duration of
Study: Department of OBS &
GYNAE Avicenna Medical College and Hospital, Lahore from January 2019 to
December 2019.
Methodolgy: A total of 90 subjects were
evaluated keeping in view the inclusion and exclusion criteria. Induction was
considered successful if the patient delivered vaginally and failed if ended up
in caesarean section.
Results: 67% ( 60 ) patients delivered by
caesarean section and 33% ( 30) by vaginal delivery. The average induction
delivery interval was 19 hours. The following factors were associated with
increased rate of failed induction : Bishop score < 5, Gestational age >
41 weeks, Oligohydramnios, Prelabor rupture of membranes, Hypertensive
disorders of pregnancy, Induction-delivery interval greater than 24 hours,
Absence of dating scan, meconium stained liquor, small for gestational age and
macrosomic babies. All were found to be statistically significant with a p
value of less than 0.05. The study also showed that induction of labour is not
associated with any major intrapartum and postpartum feto maternal
complications.
Conclusion : Most common indication for induction of labour
was post dated pregnancy. Other major indications were co morbid fetomaternal
conditions which quite seemed to be unavoidable in most cases of failed
induction. On other hand case selection for induction of labour is vital for
achieving outcomes similar to spontaneous labour.
