Background summary
Paediatric acute respiratory distress syndrome (ARDS) is a manifestation of
severe, life-threatening lung injury. Care for paediatric patient is mainly
supportive and based on what works in adults and personal experiences,
including the use of mechanical ventilation. However, differences in lung
physiology and immunology between (young) children and adults suggests that
adaptation of adult practices into paediatrics may not be justified. Recently,
we found that introduction of neuromuscular blocking agents (NMBA) resulted in
immediate improvement in oxygenation without affecting tidal volume
distribution. The mechanisms underlying this observation are unknown.
Study objective
To test the hypothesis that NMBAs in mechanically ventilated children younger
than 12 years of age with moderate-to-severe paediatric ARDS (i.e. oxygenation
index > 12 and PEEP > 5 cmH2O despite adequate sedation) reduce the
transpulmonary pressure, decrease the occurrence of patient - ventilator
dyssynchrony by reducing the respiratory rate and prevent the occurrence of
pendelluft.
Study design
Prospective observational study with invasive measurements
Study burden and risks
The risks associated with this study are minimal based on the following
arguments: patients in the intensive care unit are under constant tight
observation, so any change in vital parameters is noted immediately.
Furthermore, patients with severe lung injury are commonly deeply sedated,
blood samples are only taken from an indwelling arterial catheter, which is
already in place for clinical purposes, insertion of the oesophageal catheter
poses the same risk as insertion of nasogastric feeding tubes that are inserted
during routine care; our unit has advanced experience with inserting these
catheters, and electrical impedance tomography and electromyography
measurements are non-invasive by nature. It is important to study the effects
of neuromuscular blocking agents on patient outcome in the paediatric context.
There are numerous differences in lung physiology and immunology between
(young) children and adults indicating that adaptation of adult practices into
paediatrics may not be justified.
