INDCUTION OF LABOUR WITH FOLEYS CATETHER IN WOMEN WITH PREVIOUS ONE CAESAREAN SECTION

1. INDCUTION OF LABOUR WITH FOLEYS CATETHER IN WOMEN WITH PREVIOUS ONE CAESAREAN SECTION NURYUZILIANA D, SOFIAH S, VIJAENDREH S UNIVERISTY OF MALAYA, KUALA LUMPUR ; HOSPITAL BESAR MELAKA Objectives Methods Results Conclusions A prospective observational study conducted in Hospital Besar Melaka from 1st January 2010 till 31st December 2010. Patients with singeleton, term pregnancy and uncomplicated previous one caesarean section were recruited in this study. Our exclusion criteria were patients refused TOLAC, multiple pregnancy, PROM, 2 or more previous caesarean section, contraindication to TOLAC and previous history of uterine rupture. Bishops score was documented. Foley catheter size 16F was inserted into the intra-cervical os. It was then inflated with 40cc of water and left in situ for 24 hours. A 20 minutes cardiotocography(CTG) wasrecorded before and after the procedure. Contractions were reviewedand a repeat vaginal examination was done after 24 hours or earlier if the Foleys catheter spontaneously drop. Artificial rupture of membrane (ARM) was done for favourable cervix and labour progress was review after 4 hours. Oxytocin will only be commenced when the progress of labour was slow. In this study, failed IOL was defined as women who failed to progress to active phase of labour (unable to proceed with ARM) or had slow progress of labour after ARM and proceeded with emergency LSCS. A total of 104 patients were recruited in this study. 64 women (61.5%) had history of successful TOLAC and 40 women (38.5%) had no history of TOLAC.The indications for IOL were prolonged pregnancy/ post-datism with 49 cases (47.1%), Gestational diabetes with 35 cases (33.7%), 12 cases for hypertensive disorder (11.5%) and 8 cases for other indication such as IUGR, oligohydramnions and reduced foetal movements. 66 women had successful vaginal deliveries and the remaining 38 women underwent emergency Caesarean section, showing a success rate of 63.5%.During this study, we observed 2 women hadscar dehiscence and one with uterine rupture. All 3 women were in theactive phase of labour. It was found that favorable Bishopsscore or successful TOLAC is not positivepredictive factor for successful IOL. However, we observed that multipara women weremore likelyto have successful IOL with Foleys (p value <0.001) The option of IOL in women with previous caesarean section with Foleys catheter can be consider in future in obstetric practise. In conclusion, induction of labour with the use of an intra-cervical Foleys’ catheter in women with previous caesarean section increases the success rate of vaginal delivery and it has less complication of uterine scar ruptured. INTRODUCTION The incidence of caesarean section has increased markedly for the past 20 years it accounts for 21.3% of all births in United Kingdom, 23% in Northern Ireland, 23.3% in Australia and 26% in United State..Several steps were taken in trying to reduce it. In Malaysia similar trend is seen with current average Caesarean section rate in government hospital ranges from 20-30%, compared with about 15% in year 2006. Induction of labour (IOL) in women attempting trial of labour after a previous caesarean delivery (TOLAC) is a major concern because of the possibility increased risk of uterine rupture. Mechanical induction with Foley’s catheter had been shown less risk of uterine rupture and maternal morbidity with good success rate of vaginal delivery. OBJECTIVE To assess the outcome of induction of labour (IOL)r in women with one previous LSCS with Foleys catheter. These included looking at the rate of successful vaginal deliver and safety of the procedure. Our secondary outcome is to evaluate the predictive variables for successful IOL with Foleys catheter.
