a Randomized Multicenter Trial Comparing Vacuum Assisted Delivery With the New Device "iCUP" Versus the Reference Cup. (ICUP)

This study has been completed.

The hypothesis is that the new vacuum assisted delivery device iCup is more effective than the reference cup, in terms of maternal and newborn morbidities and functioning

Condition Intervention Phase
Vacuum Extraction, Obstetrical Randomized Controlled Trials Failures, Medical Device Maternal Lesions Neonatal Lesions Device: iCup Device: reference cup Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Assess the Risk-benefit Balance of the New Vacuum Assisted-delivery Device "iCUP" Versus the Reference Vacuum. Multicenter Prospective Randomized Controlled Study

Further study details as provided by AdministrateurCIC, University Hospital, Grenoble:

Primary Outcome Measures:
  • Composite outcome: cup detachments (failure=3 detachments), other instrument used, caesarean section, caput succedaneum, cephalohaematoma, maternal perineal lesions. If one of these criteria at least is present, outcome is noted 'failure'; else 'success' [ Time Frame: one day ]

Secondary Outcome Measures:
  • maternal lesions: cervix lesions, postpartum haemorrhage [ Time Frame: 28 days maximum ]
  • neonatal lesions: minor scalp injuries, Apgar score < 7, pH < 7.20, anaemia, jaundice, transfer [ Time Frame: 28 days maximum ]
  • medico-economic criteria: cost-effectiveness analysis of the studied medical devices [ Time Frame: 28 days maximum ]

Enrollment: 668

Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: vacuum extractor 'iCUP'
new vacuum extractor: sterile disposable plastic cup
Device: iCup
new vacuum extractor: sterile disposable plastic cup
Sham Comparator: reference vacuum extractor
reference cup of the obstetrical ward: metallic cup
Device: reference cup
reference cup of the obstetrical ward: metallic cup

Detailed Description:

Currently, instrumental extractions are used in about 10% to 15% of the 860 000 annual deliveries in France and the use of vacuum extractors increases from year to year. In addition to sterilizable vacuum extractors several different types of vacuum extractor have been developed, in particular the single use Kiwi cup or the so-called 'soft' cup extractors. However, studies evaluating these new cups have not shown their superiority in comparison to the conventional metallic vacuum extractor.

Accordingly, it is legitimate to assess the new vacuum extractor iCup, an innovative "mix" of metallic cup and 'soft' cups that should combine the advantages of both; and to compare the iCup vacuum extractor with the sterilizable metallic cup extractor, the most effective vacuum extractors available to date.
