Pivotal, Prospective, Multi-centre, Single-arm Study to Evaluate the Safety and Effectiveness of Oli for Identification of Patients, During the Intrapartum Period, Who Are at Higher Risk of Developing Abnormal Postpartum Uterine Bleeding, Including Postpartum Haemorrhage

Condition(s) studied

Investigational drug(s) / intervention(s)

Oli is a non-invasive, wearable device, designed to provide clinicians with an early indication if the participant is at a higher risk of developing abnormal postpartum uterine bleeding: Oli is a non-invasive wearable device, designed to provide clinicians with an early indication if the participant is at a higher risk of developing abnormal postpartum uterine bleeding, including postpartum haemorrhage.

Study summary

Oli is a predictive, non-invasive device, intended to be placed on the participant's maternal abdomen during the intrapartum period, which can alert healthcare professionals of an impending cumulative blood loss of ≥500 ml (abnormal postpartum uterine bleeding) or cumulative blood loss of ≥1000ml (postpartum haemorrhage) at least 1 hour in advance of birth. This study is being undertaken to assess the performance of Oli measuring cumulative blood loss ≥500ml and ≥1000ml, as well as evaluate its safety profile.

Eligibility

Primary outcome measure(s)

• Assess the performance of Oli as calculated by comparing the output of Oli (up to 1 hour prior to birth) against the clinically documented value of cumulative blood loss ≥ 500ml or any blood loss with signs and/or symptoms of hypovolemia within 24 hour — 6 months
• To assess the performance of Oli in cumulative blood loss ≥ 1000ml (ACOG) — 14 months
