Arm1-1% povidone iodine

Single vaginal Prepp will be done after anaesthesia is given, just prior to commencing Caesarean section,

Outcomes
Primary outcome [1] 323993 0
Endometritis: defined as core temperature measured >38ºc with uterine tenderness and/or foul smelling vaginal discharge

1)calling the patient 2 weekly postpartum until 28 days post discharge
2)Medical records during admission/after discharge
Timepoint [1] 323993 0
Telephonic follow up every fortnight after caesarean until 28 days post-discharge from hospital,
and
follow up during hospital presentation or admission until 28 days postdischarge
Secondary outcome [1] 383518 0
• Post-operative fever: defined as core temperature >38 ºc at any point until 7 days of post Caesarean section

The data will be collected;
1)Initially from pt at booking
2)Medical records
3)from telephonic review every fortnight till 28days post procedure
Timepoint [1] 383518 0
fortnightly after caesarean until 28days postdischarge
Secondary outcome [2] 385241 0
Wound infection: defined as itch, redness, pain, swelling and collection of purulent discharge at the surgical incision site within 7days of CS

The data will be collected;
1)Initially from pt at booking
2)Medical records
3)from telephonic review every fortnight till 28days post procedure
Timepoint [2] 385241 0
fortnightly after caesarean until 28days postdischarge

pt goes home on Day 4-5 post Caesarean section
wound is checked routinely during the stay (daily checks)
If infection present - we will be informed by Midwife or doctors
If pt develops mild infection at home and they present to GP for treatment- we can find it out at 2 weekly check which is 4+ 7 from discharge - approx 2 weeks form day of CS
If significant infection- pt will present to hospital and we can review from the records
SO fortnightly check os more consistent and doable
Secondary outcome [3] 385242 0
Readmission with infection: defined as representation of post CS patients to the hospital in 28 days of discharge with surgical site infection or related infective complications

The data will be collected;
1)Medical records
2)from telephonic review every fortnight till 28days post procedure
3)Directly from the patient during inpatient admission
Timepoint [3] 385242 0
fortnightly after caesarean until 28days postdischarge

Eligibility
Key inclusion criteria
Any patients undergoing for either emergency or elective CS that provided voluntary informed consent will be included in the study.
Minimum age
16 Years
Maximum age
No limit
Sex
Females
Can healthy volunteers participate?
No
Key exclusion criteria
• Patients having signs of chorio, intrapartum pyrexia and other signs of infection will be excluded from the study.
• Patients who develop intrapartum pyrexia as a result of syntocinon drip, prolonged labour or obstructed labour and provided voluntary informed consent will be included in the study initially. Their placental swabs will be taken for microscopic examination, culture and sensitivity (m/cs). They will be excluded from the study only if their swab results are positive for m/cs.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After inclusion in the trial, each prospective CS patient will be assigned either into the intervention (1% povidone iodine or chlorohexidine) or control (no-irrigation) group by using a block randomization technique. A permuted block of six will be used to randomize the patients. A third party not related to the study will generate the permuted blocks and allocate the treatment in sealed opaque envelops.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Efficacy
Statistical methods / analysis
We assume that the interventions will improve the rate of infection including post-operative infective complications (within 28 days of discharge from the hospital) by 50% compared to the control. Thus, for sample size estimation in this study we set P1 =8% (as per overall prevalence of post CS infection range 3-15%), P2 = 4%, significance level = 5% and the study power =80%.
Therefore, n = Za + Zß 2
ES
ES= P1-P2
vP1(1-P1)

n = 361
Here, Za = 1.96, Zß = 0.84, P1= 0.08, P2 =0.04, and P1-P2= 0.04.
Considering 5% drop out, the study will require recruiting approximately 375 participants for all the groups and 125 in each group over a period of sixteen (16) months to adequately test the assumption.

Summary
Brief summary
General Objective
To introduce uniform use of vaginal antiseptic wash immediately prior to Caesarean section and to determine the best antiseptic wash material in reducing post-operative infections or complications.

Specific Aims
1. To determine the number of post-CS infections among women that will undergo pre-operative vaginal cleansing with either 1% povidone iodine or chlorohexidine or no toileting (control) during elective CS
2. To determine the number of post-CS infections among women that will undergo pre-operative vaginal cleansing with 1% povidone iodine or chlorohexidine or no toileting (control) during emergency CS
3. To compare the rate of infections among the three groups that receiving either 1% povidone iodine or chlorohexidine or no toileting for vaginal irrigation prior to any kind of CS
4. To identify the best antiseptic wash and methods for vaginal irrigation prior to CS for developing a uniform guideline through locally generated evidence
5. To determine the factors that may influence the outcomes such as post-CS infections or related complications
