AIM-The aim of this study was to compare the efficacy of induction of labour with Foley balloon inflation to 60ml with sublingual misoprostol. MATERIALS AND METHODS -This randomised controlled trial (n= 320) was performed on women with singleton pregnancy with cephalic presentation and unfavourable cervix admitted in RG Kar Medical College during the period of July 2011 to June 2012. In Foley group, labour was induced by placing No. 20 transcervical Foley catheter and inflating the balloon to 60 ml along with intravenous oxytocin. In Misoprostol group, sublingual misoprostol was used, 25 mcg every 4 hours to a maximum of 5 doses until adequate uterine contractions. Intravenous oxytocin was administered in patients with protraction or arrest disorders. RESULTS -The two groups were similar in demographic characteristics, indication for induction, pre-induction Bishop score, maternal and fetal complications. Time from induction to delivery was significantly shorter in Foley catheter group compared to misoprostol group(15.19+2.83 vs 16.16+3.35 hr, p<0.05). Mean post induction Bishop Score at 6 hours and 12 hours was significantly higher in Foley catheter group compared to misoprostol group (5.98+1.46 vs 4.95+1.33 and 8.45+1.5 vs 7.12+1.6, p<0.05). CONCLUSION -labour induction with Foley catheter is a safe and effective method of with less induction to delivery time. It avoids the side effects of misoprostol like nausea, vomiting, diarrhoea, fever shivering as well as uterine complications like tachysystole, rupture, and fetal death. CLINICAL SIGNIFICANCE -Induction of labour by Transcervical foley is a better alternative to misoprostol and should me more widely used.

“…Labour must be induced artificially when benefits of termination of pregnancy outweighs those of continuing pregnancy. Currently a quarter of all pregnant women in industrialized countries undergo artificial induction of labour [1] . For induction of labour two different approaches are used, which are often used in combination.…”

“…Induction of labor (IOL) is a common practice in obstetrics and is followed in many countries with rates ranging from 1.4–35% [ 1 , 2 ]. A recent publication revealed that the rate of IOL was 23.4% in the United States, 22.1% in the United Kingdom, 4.4% in African regions, 11.4% in Latin America, and 12.1% in Asian countries [ 2 ].…”

The objective of this study was to determine the value of uterocervical angle (UCA) in predicting successful induction of labor (IOL) in singleton pregnant women compared to the Bishop score and cervical length (CL). A total of 205 normal term, singleton labor-induction cases were analyzed. Successful IOL was defined as the onset of active labor of induction. A comparative analysis was performed to evaluate the effectiveness of UCA, Bishop score, and CL in predicting IOL. Compared to the non-successful IOL group, the women in the successful IOL group had significantly wider UCA (p = 0.012) and higher Bishop score (p = 0.001); however, the CL was not significantly different (p = 0.130). UCA alone did not perform better than the Bishop score when predicting successful IOL. However, UCA combined with the Bishop score showed higher performance in predicting IOL (combined UCA > 108.4° and favorable Bishop score as sensitivity of 44.6%, specificity of 96.0%, PPV of 96.2%, and NPV of 43.6; combined UCA > 108.4° or favorable Bishop score as sensitivity of 85.7%, specificity of 50.0%, PPV of 78.7%, and NPV of 61.9). In conclusion, UCA combined with Bishop score may be an effective sonographic method for predicting successful IOL.

“…The case of uterine rupture was recorded in the study that used 100 µg of misoprostol [17]. The rate of induction is on the increase, 35.5% in Sri Lanka, 24.5% in USA, 33% in Europe, 12.7% in Ibadan Nigeria and 11.5% in Abakaliki [3] [18]. Studies on maternal mortality in Ebonyi State have reported high maternal mortality ratios both in the rural and urban areas where uterine rupture was reported as a major cause due to injudicious use of uterotonics [19] 2) To determine the effective and safe dosage of misoprostol for cervical ripening and induction of labor for our clients.…”

Background: Cervical ripening is prerequisite of successful induction of labor. Vaginal misoprostol and Foley's catheter placement have been widely used for this purpose but the data are not always sufficient. We attempted to determine which (misoprostol versus Foley's catheter) is more effective/safer in Nigerian setting. Methods: A randomized controlled trial was performed at Federal Teaching Hospital Abakaliki, Nigeria, involving 135 term pregnant women requiring cervical ripening and labor induction. Participants were randomly allocated to misoprostol versus catheter group. The following were recorded/measured/analyzed: Bishop's score, age, parity, body mass index, gestational age, labor duration, indication, oxytocin use, mode of delivery, and Apgar score. Chi square test and t test were used where appropriate. Results: At 24 hours, all of misoprostol group were either in labor, had ripe cervix, or had delivered, whereas 35.4% of catheter group had still unripe cervix (x 2 = 29.856, P = 0.0001). Misoprostol group was less likely to require oxytocin infusion (x 2 = 52.600, P = 0.0001) and less likely to require cesarean delivery (cesarean: misoprostol versus catheter: 11% versus 34% (x 2 = 9.800, P = 0.001)). Total medical cost for misoprostol was less than that of catheter (x 2 = 14.703, P = 0.0001). Conclusion: 50 μg vaginal misoprostol, compared with catheter placement, was more effective, cheaper, and safe as a procedure of cervical ripening before induction of labor.
