Interventional
Description of intervention(s) / exposure
Participants will be given patient information and a consent form.

The intervention is the surgical skin closure technique. The participant’s caesarean section skin layer will be closed with the standard suture material used for caesarean sections which is 3/0 Monocryl suture. It will be closed in the standard manner in a subcuticular technique. The final closure of the skin will be modified to the novel knot-free technique which is being studied. The proposed skin closure technique does not add any extra time to the standard skin closure technique which is less than 5 minutes.The proposed technique is described step-wise below:
- Step 1: Perform routine subcuticular suture from distal end (assistant end) to proximal end (surgeon end). Bring needle out precisely at apex of wound.
- Step 2: Pull suture through to re-approximate wound without excessive tension and puckering in the skin.
- Step 3: Loop and bring the needle back under where the suture exited the wound at the apex.
- Step 4: Bring the needle out of the skin approximately 5-10mm below the wound
- Step 5: Re-enter the skin 2mm medial to the previous exit point, and bring the needle out of the skin 5-10mm above and medial to the apex of the wound
- Step 6: Cut suture flush to skin
- Step 7: Apply adhesive Steri-strips the proximal apex of the wound

The intervention will be performed by Obstetricians (>6 years experience), or Obstetric Registrars (variable experience) under the supervision of Obstetricians.

Adherence will be monitored by having a research team member present at the time of intervention.

This intervention will be performed in a secondary-level teaching hospital.

Participants will be followed up over a period of 6 weeks from the day of delivery. Participants will undergo daily wound review whilst in the hospital, as is standard protocol at the study site. In addition to this standard of care, participants will be asked to provide two pieces of follow-up data to track safe wound healing: (1) A short questionnaire screening for safety concerns with regard to appropriate wound healing; and (2) A photo of the wound to track wound healing progress. The questionnaire has been designed specifically for this study.
Participants will be required to send this questionnaire and photo via email to the researcher’s secure email account on Day 5 and 6 weeks postoperatively.
