Brief summary
The investigators propose to evaluate premedication with Propofol compared to a control strategy including a placebo with a possible rescue treatment with ketamine to ensure pain control before LISA Procedure . Investigators hypothesize that sedation with Propofol is safe and non-inferior to placebo for the risk of Mechanical Ventilation in the 72 hours following the procedure.
Detailed description
Non-inferiority trial comparing Propofol versus placebo during the intra tracheal Less Invasive Surfactant Administration (LISA) in preterm babies \< 32 weeks of gestation for the need for mechanical ventilation after the procedure. An open-label ketamine treatment as rescue is possible in each group. In each participating unit, information will be given to parents of preterm babies \<32 wGA upon their admission to the delivery room or to the NICU (neonatal intensive care unit), and informed consent will be sought as soon as possible. Eligible babies presenting a RDS (respiratory distress syndrome) will be included and randomized to the control (placebo) group or Propofol group. While benefiting from Nasal Intermittent Positive Pressure Ventilation (NIPPV) the newborn will be prepared as usual for tracheal intubation. Trialists will be blinded to treatment allocation. The drug administration in the two groups will be titrated according to weight (0.5mg/kg per dose of Propofol or a similar volume of placebo). Before and after each dose, a pain score (FANS) will be quickly evaluated within 2 minutes of the injection, to assess the need for a supplementary dose (up to a predefined limit) or rescue treatment by Ketamine, also according to the clinician's clinical impression . After the steps of sedation, the LISA procedure will be performed, with detailed data collection of per procedure events up to 72 hours of life. Babies will be subsequently managed as usual in each NICU and data will be collected about respiratory, neurological and hemodynamic outcomes during the hospital stay, and especially at discharge, 28 days, and 36 weeks. At two years of corrected age, a final examination will be performed to evaluate neurodevelopmental outcomes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| need for mechanical ventilation after the procedure | 72hours | Rate of mechanical ventilation from the start of the LISA procedure up to 72 hours of life Pain before procedure (need of ketamine administration) or within 1 hour following first injection of propofol/placebo (FANS score ≥ 6) |
Secondary
| Measure | Time frame | Description |

An easy intubation would obtain a low score and a difficult intubation would have a high score. |

| At two years of corrected age: ASQ (Ages and Stages Questionnaire) | 2 years (corrected age) | ASQ (Ages and Stages Questionnaire) questionnaire is a general developmental screening tool (5 areas are evaluated: Communication, gross motor, fine motor, problem solving, and personal-social). Total score is the sum of each of the 5 area scores (wich are between 0-60. Total score is between 0 and 300. The higher the score is, the best developed the children is. |
| At two years of corrected age: motor function | 2 years (corrected age) | Gross Motor Function Classification Scale (GMFCS) looks at movements such as sitting, walking and use of mobility devices. It is helpful because it provides families and clinicians with a clear description of a child's current motor function, and an idea of what equipment or mobility aids a child may need in the future, e.g. crutches, walking frames or wheelchairs. Participant will be assignated to one of the 5 levels by the clinicians : a patient who is in level 5 has more motor impairments than a patient in level 1. |
| At two years of corrected age: vision | 2 years (corrected age) | Visual functions : a clinical examination will conclude if the participant has a visual deficit or not. And in the deficit case, what kind of vision pathology. |
| At two years of corrected age: audition | 2 years (corrected age) | Hearing functions : a clinical examination will conclude if the participant has a hearing deficit or not. And in the deficit case, what kind of audition pathology. |
