Effect of Vaginal pH on Efficacy of Prostaglandin Gel for Labour Induction

Abstract

Background: Inducing Labour Is A Procedure Intended To Trigger Artificial Contractions Of The Uterus That GenerallyInvolve Progressive Erasure And Dilation Of The Cervix. This Will Hopefully Lead To The Birth Of A Baby Through TheVaginal Route.Objective: To Assess The Effect Of Vaginal Ph On Efficacy Of Prostaglandin Gel For Labour InductionMethods: A Total Of 200 Women With An Unfavourable Cervix Were Enrolled In This Retrospective Study. In Group I,There Were 100 Cases With Vaginal Ph Of ≤4.5 And In Group Ii, 100 Cases With Vaginal Ph Of > 4.5. Patients With MinimalChange In Bishop Score, Received Up To 3 Doses Of Prostaglandin Gel Intracervically, 6 Hours Apart. Women Who HadNo Change In Bishop Score At The End Of Induction With 3 Doses Of Prostaglandin Gel, Were Further Reassessed.Results: In Terms Of Maternal Age, Parity, Gestational Age, And Initial Bishop Score, There Was No Significant DifferenceBetween The Two Groups. Prior To Induction Of Labour, The Average Bishop Score Was 3.6±0.9 In Group I And 4±1.0 InGroup Ii. Out Of 200 Cases, 33% Cases Required Oxytocin Infusion In Group I And 13% In Group Ii.Conclusion: Parity Has A Major Impact On The Pre-Induction Of The Bishop Score And The Ph Itself Has A VaginalInfluence. Knowing The Pre-Induction Vaginal Ph May Also Be A Helpful Method For Determining The Outcome OfPge2 Induction.
