Invasive Mechanical Ventilation
Brief summary
A UK multi-centre cluster randomised controlled trial to determine if a protocol-based intervention incorporating coordinated care with greater nursing involvement to managing sedation and ventilator weaning can reduce the duration of invasive mechanical ventilation and is cost effective compared with usual care in children in Pediatric Intensive Care Units.
Detailed description
Mechanical ventilation is a common lifesaving therapy, but the longer a child remains on the ventilator, the more risk they have of developing problems. For this reason, getting the child off the ventilator (called weaning) is an important patient outcome. Sedative drugs are necessary so the child can tolerate the breathing tube, but too much can make them sleepy and delay coming off the ventilator. In 2014, visits to 24 Paediatric Intensive Care Units (PICUs) were conducted and it was found that weaning was usually performed by doctors and occasionally senior nurses, but weaning was not always done the same way and, because everyone was not involved, it was often disjointed. This study will determine if a coordinated approach by doctors and nurses to optimise sedation and weaning using guidelines will: (a) reduce how long patients are on a ventilator without causing any increased risk; (b) reduce the time children spend in a PICU and the hospital; (c) be cost effective in the NHS; and (d) be easily adopted by staff delivering care. Children receiving ventilation, except those that will never come off a ventilator, will be weaned using the guidelines. Data collection will start in all PICUs at the same time from the very beginning of the study when they are weaning children according to usual practice. Each month, one unit will be chosen at random and staff will be trained to use the new guidelines. The unit will continue using the new guidelines for the rest of the trial. Outcome data collected before (usual care) and after (intervention) training will be compared. An evaluation of the process of implementing the new intervention will be undertaken. During the process evaluation, study staff will be interviewed about their experiences and views with the new approach.
Interventions
A protocol based intervention incorporating co-ordinated care with greater nursing involvement; patient-relevant sedation plans linked to regular assessment using the COMFORT scale; regular assessment of ventilation parameters with a higher than usual trigger for undertaking an extubation readiness test; a spontaneous breathing trial (SBT) on low levels of respiratory support to test extubation readiness
Usual sedation and weaning management that is not protocol based
