Premedication for Less Invasive Surfactant Administration (LISA-Med)

Early respiratory management of preterm infants immediately after birth should be as gentle as possible. With this so-called developmental approach, unnecessary invasive methods can be avoided or at least postponed. This kind of "soft landing" allows cardiorespiratory transition with fewer adverse outcomes. Less invasive surfactant administration (LISA) is a technique that involves delivery of surfactant to a spontaneously breathing infant through a thin catheter. This technique minimizes the risk for neonatal lung injury caused by positive pressure ventilation. LISA is nowadays widely used in neonatal intensive care units (NICU). Although less invasive, newborns exposed to this procedure need premedication prior the procedure. There is no consensus, which drug would be the optimal premedication for LISA and the research on this topic is lacking. An ideal premedication would treat the procedural pain without suppressing the infant's own breathing. The sedation and analgesia should start fast but the effect should be short-acting with as few adverse effects as possible. The aim of this randomized, controlled trial (RCT) is to evaluate the feasibility, efficacy and safety of LISA protocol with the premedication of either ketamine or fentanyl by investigating whether one or the other is associated with lower rate of adverse events, hence would be preferred choice for premedication protocol.

Study Overview

• Status: Recruiting
• Conditions: Surfactant Deficiency Syndrome Neonatal
• Intervention / Treatment: Drug: Ketamine; Drug: Fentanyl

Detailed Description

All infants fulfilling the inclusion criteria during the study period are asked to participate in this randomized controlled trial of LISA premedication. Written informed parental consent is acquired from all of the participants. After the consent, individuals needing the LISA will receive premedication as follows: caffeine (in case of gestational age <32 weeks and not already given), glycopyrrolate, and randomly either ketamine or fentanyl. The investigators and medical staff are blinded to the fact which study medication is given. This study is a pilot study and 20 patients are recruited for both groups. Randomization is done in the blocks of four.

S-ketamine (Ketanest-S 5 mg/ml) or fentanyl (Fentanyl-Hamel diluted to 5 μg/ml) is used as a masked study drug. Both study drug solutions appear equally transparent. Drug administration is started with glucopyrrolate (Robinul 0.2 mg/ml), which is given intravenously at a dose of 5 µg/kg. Thereafter, the masked study drug is administered intravenously slowly in one to two minute injection of 0.2 ml/kg. In this way, doses of S-ketamine 1 mg/kg or alternatively fentanyl 1 μg/kg is received. After five minutes (from the beginning of administration of the study drug), videolaryngoscopy is started. If the study drug does not have sufficient effect, the study drug may be repeated with the same dose. If study drug fails to give appropriate conditions to LISA procedure, midazolam 0,1 mg/kg can be used as an additional drug.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Child; Adult; Older Adult
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• Gestational age at birth ≥26 weeks
• Respiratory insufficiency managed with non-invasive respiratory support (nasal continuous positive airway pressure or high-flow)
• Requirement for oxygen to maintain oxygen saturation in the target range and need for surfactant treatment (according to clinician's assessment)
• If further doses of surfactant are needed, patient can be re-randomized

Exclusion Criteria:

• Severe RDS with high oxygen requirements, severe respiratory acidosis and/or widespread atelectasis radiologically, such that ongoing ventilator support will be necessary after surfactant therapy (intubation in preferable to LISA if FiO2 >40% at GA <28 weeks and >60% at GA ≥28 weeks)
• Maxillo-facial, tracheal or known pulmonary malformations
• Any known chromosomal abnormality or severe malformation
• An alternative cause for respiratory distress (e.g. congenital pneumonia or pulmonary hypoplasia)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Adverse event	The need of positive pressure ventilation (PPV), intubation, heart rate below 80 per minute, mean arterial pressure change more than 20%, pH change more than 0.4, and CO2 change more than 20%, and saturation <85 for more than 1 minute	1 hour

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Duration of the procedure	Duration of the procedure is evaluated retrospectively from the recording of the videolaryngoscopy (an attempt begins when the laryngoscope enters the mouth and ends with LISACath in the trachea)	1 hour
Number of attempts to get the catether intratracheally	Number of attempts to get the catether intratracheally is evaluated retrospectively from the recording of the videolaryngoscopy (one laryngoscopy = one attempt)	1 hour
Pain score NIAPAS	Pain will be scored with validated Neonatal Infant Acute Pain Assessment Scale (NIAPAS) tool. The scale includes five behavioral and three physiological indicators, and takes into account the gestational age of neonates as a contextual factor. The indicators are rated on a 2, 3, or 4-point scale for a possible total score of 18. Assessments of each neonate include alertness, facial expressions, crying, muscle tension, reaction to handling, and breathing. In addition, the neonates on monitors are assessed for changes in heart rate and oxygen saturation (Copyright Pölkki T, Korhonen A, Axelin A. 2013)	1 hour
The need for additional dosing of study drug or midazolam (number of addtional dosages)	If the study drug does not have sufficient effect, the study drug may be repeated with the same dose. If study drug fails to give appropriate conditions to LISA procedure, midazolam 0,1 mg/kg can be used as an additional drug.	1 hour
Edi-signals	Special Edi (Electronic Diaphragm Monitoring) Catheter is placed to read the electrical activity of the diaphragm. Edi min and Edi max in different time points will be collected.	1 hour
