The purpose of this study is to examine whether obese women (BMI \>= 30) who give birth by caesarean section have a reduced incidence of wound infection and dehiscence when incisional Negative Pressure Wound Therapy is applied prophylactically following caesarean section.
This study is a non-blinded randomised controlled trial and a concurrent Health Economic Evaluation. The study examines the effect on wound healing using incisional Negative Pressure Wound Therapy (iNPWT) compared with standard postoperative dressings in women with a BMI \>= 30, who has a Caesarean Section (CS). We expect to find a lower frequency of wound complications when using iNPWT directly on primary suturing compared to standard postoperative dressings in this high-risk subpopulation. Women, who have given informed consent, will be randomised to either intervention or control group via a computer-generated randomisation program. Elective and emergency CS will be stratified to ensure roughly equal numbers in each category of CS in each arm of the study and permit valid separate and pooled analysis. The analysis will be carried out on an intention to treat basis. The iNPWT or standard postoperative dressings will be applied in theatre immediately following the operation. In the intervention group the therapy will be left in situ for five days corresponding to the date of removal of stitches. In the control group the dressing will be left in situ for at least 24 hours as standard procedure. Women, who do not wish to participate, will be asked for permission to use their data in the analysis.

The Incisional Negative Pressure Wound Therapy (iNPWT) will be applied over the clean closed incision immediately following the operation (caesarean section). In the intervention group the therapy will be left in situ for five days.
A standard wound dressing will be applied over the clean closed incision immediately following the operation (caesarean section). In the control group the dressing will be left in situ for at least 24 hours as standard procedure.

The incidence of post-CS wound infection in each study group
Wound infection requiring antibiotic treatment To be able to collect information about symptoms of infection after discharge a self-administered questionnaire will be sent to all participants within 30 days post-CS. Furthermore data on postoperative infections, recorded by diagnoses codes or surgical procedures, will be obtained from the Danish National Patient Registry
Time frame: Within the first 30 days after surgery
Length of the primary and any secondary hospitalization
Primary for the health economic evaluation
Time frame: Within the first 30 days after Caesarean Section
Readmissions to hospital/contact to the general practitioner on suspicion of infection following caesarean section
Primary for the health economic evaluation
Time frame: Within the first 30 days after Caesarean Section
Number of Participants with a decreased health-related quality of life score as a measure of satisfaction and tolerability
A health-related quality of life measure, recorded in Quality Adjusted Life Years at the two interventions. The health-related quality of life score is measured 5 and 30 days post-CS. Primary for the health economic evaluation
Time frame: Within the first 30 days after Caesarean Section
Antibiotic treatment on suspicion of infection after Caesarean Section
Primary for the health economic evaluation
Time frame: Within the first 30 days after Caesarean Section
The cosmetic outcome as a measure of satisfaction
The scar will be evaluated by a plastic surgeon at a clinical examination 6 and 12 months post-CS. After study completion pictures of the scars will be evaluated by two unbiased plastic surgeons, using two predefined scar scales.
Time frame: A 6 and 12 months follow-up
Other wound complications after caesarean section
wound separation, wound exudate
Time frame: Within the first 30 days after Caesarean Section
