Brief Summary:
Necrotizing enterocolitis (NEC) affects up to 10% of very preterm infants. NEC mortality is high (30-50 %) and has remained unchanged over the last decades. New treatments are urgently needed. NEC pathogenesis is multifactorial, but bowel ischemia plays an essential role in NEC development. Remote ischemic conditioning (RIC) consists in inducing brief periods of non-lethal ischemia in a limb distant to an organ suffering from ischemia. RIC has been used in adults, children and term neonates with a variety of diagnosis. However, no study has been done including preterm infants with NEC.

Condition or disease Intervention/treatment
Enterocolitis, Necrotizing Procedure: Remote ischemic conditioning

Detailed Description:
An appropriately sized blood pressure cuff will be applied to an arm or leg and inflated to promote RIC. This study will be conducted in three phases to assess the feasibility and safety of RIC in relation to duration of ischemia time, number of cycles of RIC and whether it is feasible and safe to perform RIC on consecutive days.

Intervention Details:
  • Procedure: Remote ischemic conditioning
    An appropriately sized blood pressure cuff will be inflated around a limb (systolic blood pressure + 15 mmHg) for different periods of time (1 to up to 4 minutes), times (1 to up to 4 times) and consecutive days (1 to up to 2).

Primary Outcome Measures :
  1. Limb perfusion after Remote Ischemic Conditioning [ Time Frame: 1 days ]
    Limb perfusion will be assessed before (baseline) and after Remote Ischemic Conditioning (RIC). Limb perfusion will be determined by oxygen saturation using pulse oximetry. RIC will be considered feasible and safe if the procedure is completed as planned with no failure of limb re-perfusion. Failure is defined as no return of limb arterial oxygen saturation to baseline 4 minutes after the ischemic phase (re-perfusion time).

Secondary Outcome Measures :
  1. Cutaneous injury [ Time Frame: 1 days ]
    Defined as new-onset skin breakdown, bruising, ecchymosis or petechiae.

  2. Persistent pain [ Time Frame: 1 days ]
    Pain measured according to the premature infant pain profile (PIPP) scores (range 0-21). Pain scores will be obtained immediately before (baseline) and 6 hours after RIC. Persistent pain will be defined as a PIPP score higher than the baseline score.
