Study summary

A randomized controlled, parallel group, superiority, open-label, single-institution, Phase 3 interventional clinical trial to evaluate clinical outcomes in obese gravidas undergoing elective cesarean delivery whose wounds were dressed with the PICO Negative Pressure Wound Therapy (NPWT) versus the standard dressing. We hypothesize that the PICO NPWT will reduce the incidence of surgical site occurrences and interventions and postoperative readmissions in obese women. The study will compare surgical site occurrences and surgical incision intervention incidence within 42 +/- 10 days post cesarean delivery in obese women who have the current standard-of-care dressing versus the PICO NPWT.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Study arms

  • Experimental
    PICO Dressing

    PICO Negative Pressure Wound Therapy (Smith and Nephew Healthcare, Hull, United Kingdom) is a non-significant-risk, FDA Class II, medical device commercially available in the USA. The PICO unit is a single patient use, battery-powered, disposable unit that can provide continuous 80 - 125 mmHg negative pressure over a 5 to 7-day therapy period.

    Device: PICO Negative Pressure Wound Therapy

  • Active comparator
    Standard Dressing

    The standard-of-care is consistent with the national standard for dressing Cesarean section incisions and includes, but not limited to, coverage of the sutured incision with sterile gauze and non-penetrable barrier (e.g., Tegaderm™). The non-penetrable barrier may be left in place for a minimum of 1 day and no longer than 2 days (± 4 hours) to promote epithelialization of the surgical incision edges. After the dressing is removed, the surgical site is left exposed to air to promote further healing.

    Device: Standard Dressing

Interventions

  • DevicePICO Negative Pressure Wound Therapy

    The PICO unit is a single patient use, battery-powered, disposable unit that can provide continuous 80 - 125 mmHg negative pressure over a 5 to 7-day therapy period.The dressing is applied to the wound and extra strips are placed over the outside edge to help hold the dressing in place. When the pump is turned on, air is pulled out of the dressing and excess fluid from the wound will start to enter the dressing.

    Also known as: PICO Dressing

  • DeviceStandard Dressing

    The standard-of-care is consistent with the national standard for dressing Cesarean section incisions and includes, but not limited to, coverage of the sutured incision with sterile gauze and non-penetrable barrier (e.g., Tegaderm™). The non-penetrable barrier may be left in place for a minimum of 1 day and no longer than 2 days (± 4 hours) to promote epithelialization of the surgical incision edges.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 29, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
