Review of Literature
In a study done by zhang, et al, in 2011, involving 15,054 women from 6 hospital who received oxytocin (stating dose and incremental dosing of 1,2, and4 mu/min) for augmentation of labour.Study conclude high dose oxytocin regimen is associated with a shorter duration of first stage of labour for all parities without increasing the caesarean delivery rate or adversely affecting perinatal outcomes1.
Cochrane review done by Mori et al, from the four RCT involving 660 pregnant women requiring labour augmentation by oxytocin comparing high and low dose.The results showed reduction in length of labour and caesarean section and no significant difference for neonatal mortality, hyperstimulation and APGAR scores2
In a Systematic review of ten RCT, the studies contrasting 2 intervention for labour augmentation: high dose Vs low dose oxytocin done by Shu-Qin wei et al. The results suggest moderate decrease in caesarean section rate and labour duration and increase in spontaneous vaginal delivery. While hyper stimulation was increased with high dose, there was no evidence of increase in maternal or neonatal morbidity3.
In a study done by patka, et al, included clinical trials comparing high versus low-dose ocytocin for augmentation labour.High dose oxytocin for augmentation of labour, showed decrease duration of labour but does not appear to decrease caesarean section rates4.
In a RCT done by Jamal et al, involving 200 pregnant women, who received high dose or low dose oxytocin protocol for augmentation of labour. The study concluded- high dose oxytocin is associated with significantly shorter labour without any adverse fetal and maternal outcome5.
In a RCT done by Tabovei et al, involving 448 nulliparous women, who received high or low dose oxytocin for augmentation of labour.The study showed active management with high dose oxytocin is associated with shortened labour, decreased caesarean section there were no significant difference in maternal and neonatal morbidity between two groups6.
In a RCT done by Merrill et al, high dose compared with low dose oxytocin for augmentation and induction of labour. Study showed high dose oxytocin is associated with significantly shorter labours without any demonstrable Fetal or neonatal effects7.
In a RCT done by Rebecca and George [1997], involving 405 nulliparous women, who received either high or low dose oxytocin for active management of labour. High dose oxytocin had shortened labour duration, reduced caesarean section. Maternal and fetal outcomes did not vary significantly between 2 groups8
In a RCT done by Elly and Xenakis 310 term pregnancies who received either high dose or low dose oxytocin augmentation regimen.Study showed lower caesarean section rate regardless of parity with no difference in maternal complications and neonatal outcome9
In a RCT done by Adrew et al involving 2788 pregnancies requiring augmentation of labour, either with high or low dose oxytocin. Result showed significantly fewer caesarean section and forceps delivery with high dose oxytocin. Although high dose oxytocin was associated with utrine hyper stimulation, no adverse fetal outcome were observed10.
In a RCT done by Bid good and Steer, involving 60 women why who were progress slowly in spontaneous labour were assigned to 3 management protocol (No oxytocin, low dose oxytocin, High dose oxytocin). Significant decrease in delay to delivery duration with high dose protocol. There were no measurable difference in newborn condition between 3 groups11.
