Abstract
OBJECTIVES To map the evidence for ventilation liberation practices in pediatric respiratory failure using the Realist And MEta-narrative Evidence Syntheses: Evolving Standards publication standards. DATA SOURCES CINAHL, MEDLINE, COCHRANE, and EMBASE. Trial registers included the following: ClinicalTrials.gov, European Union clinical trials register, International Standardized Randomized Controlled Trial Number register. STUDY SELECTION Abstracts were screened followed by review of full text. Articles published in English language incorporating a heterogeneous population of both infants and older children were assessed. DATA EXTRACTION None. DATA SYNTHESIS Weaning can be considered as the process by which positive pressure is decreased and the patient becomes increasingly responsible for generating the energy necessary for effective gas exchange. With the growing use of noninvasive respiratory support, extubation can lie in the middle of the weaning process if some additional positive pressure is used after extubation, while for some extubation may constitute the end of weaning. Testing for extubation readiness is a key component of the weaning process as it allows the critical care practitioner to assess the capability and endurance of the patient's respiratory system to resume unassisted ventilation. Spontaneous breathing trials (SBTs) are often seen as extubation readiness testing (ERT), but the SBT is used to determine if the patient can maintain adequate spontaneous ventilation with minimal ventilatory support, whereas ERT implies the patient is ready for extubation. CONCLUSIONS Current literature suggests using a structured approach that includes a daily assessment of patient's readiness to extubate may reduce total ventilation time. Increasing evidence indicates that such daily assessments needs to include SBTs without added pressure support. Measures of elevated load as well as measures of impaired respiratory muscle capacity are independently associated with extubation failure in children, indicating that these should also be assessed as part of ERT.

Ventilator weaning and extubation practices in critically ill children: An Australian and New Zealand survey of practice. Aust Crit Care 2022:S1036-7314(22)00090-X. [PMID: 36038459 DOI: 10.1016/j.aucc.2022.06.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 06/22/2022] [Accepted: 06/26/2022] [Indexed: 10/15/2022] Open
Abstract
OBJECTIVES We aimed to (i) describe current weaning and extubation practices in children (protocols to identify weaning candidates, spontaneous breathing trials, and other aspects of care such as sedation weaning) and (ii) understand responsibilities for ventilation weaning decisions across Australia and New Zealand (ANZ). METHODS A cross-sectional survey of ANZ intensive care units who routinely intubate and ventilate children (<18 years) was conducted. We worked with the Australian and New Zealand Intensive Care Society Paediatric Study Group to identify units and potential respondents (senior nurse representative per unit) and to administer questionnaires. Survey questions (n = 35) examined current protocols, practices, unit staffing, and decision-making responsibilities for ventilation weaning and extubation. Open-ended questions examined respondents' experiences of weaning and extubation. RESULTS A senior nursing respondent from 18/22 intensive care units (82%) completed the survey. Across units, most used sedation assessment tools (88%), and less often, sedation weaning tools (55%). Spontaneous awakening protocols were not used; one unit (5%) reported the use of a spontaneous breathing protocol. Two respondents reported that ventilation weaning protocols (11%) were in use, with 44% of units reporting the use of extubation protocols. Weaning and extubation practices were largely perceived as medically driven, with qualitative data demonstrating a desire from most respondents for greater shared decision-making. CONCLUSION In ANZ, ventilation weaning and extubation practices are largely medically driven with variation in the use of protocols to support mechanical ventilation weaning and extubation in children. Our findings highlight the importance of future research to determine the impact of greater collaboration of the multidisciplinary team on weaning practices.

Abstract
BACKGROUND Published reports of complex interventions in randomized controlled trials often lack sufficient detail to allow trial replication and adoption into practice. AIM The aim of this paper is to describe our experience of using the Template for Intervention Description and Replication (TIDieR) checklist in reporting a recent trial of sedation and ventilation weaning in critically ill children (the Sedation and Weaning in Children [SANDWICH] trial). METHODS The TIDieR 12-point checklist has been used to detail and describe the specific SANDWICH trial intervention and methods of implementation. RESULTS/DISCUSSION Overall, we found the checklist a useful tool to direct and ensure consistency of reporting of our complex intervention used in a multi-centre clinical trial. We experienced some minor limitations in classifying training materials and delivery mode into one item because of the overlapping nature of this component. CONCLUSION Using the TIDieR checklist to report complex interventions tested in trials provides a structured, systematic way of describing necessary detail. This allows clinicians to understand the theory behind the intervention, how it should be delivered, and the resources required. RELEVANCE TO CLINICAL PRACTICE The SANDWICH intervention had a significant beneficial effect on reducing time on ventilation for children. The detailed description of the team-based intervention will aid replication, implementation and monitoring of fidelity in other paediatric intensive care units.

Abstract
BACKGROUND Daily assessment of patient readiness for liberation from invasive mechanical ventilation can reduce the duration of ventilation. However, there is uncertainty about the effectiveness of this in a paediatric population. OBJECTIVES To determine the effect of a ventilation liberation intervention in critically ill children who are anticipated to have a prolonged duration of mechanical ventilation (primary objective) and in all children (secondary objective). DESIGN A pragmatic, stepped-wedge, cluster randomised trial with economic and process evaluations. SETTING Paediatric intensive care units in the UK. PARTICIPANTS Invasively mechanically ventilated children (aged < 16 years). INTERVENTIONS The intervention incorporated co-ordinated multidisciplinary care, patient-relevant sedation plans linked to sedation assessment, assessment of ventilation parameters with a higher than usual trigger for undertaking an extubation readiness test and a spontaneous breathing trial on low levels of respiratory support to test extubation readiness. The comparator was usual care. Hospital sites were randomised sequentially to transition from control to intervention and were non-blinded. MAIN OUTCOME MEASURES The primary outcome measure was the duration of invasive mechanical ventilation until the first successful extubation. The secondary outcome measures were successful extubation, unplanned extubation and reintubation, post-extubation use of non-invasive ventilation, tracheostomy, post-extubation stridor, adverse events, length of intensive care and hospital stay, mortality and cost per respiratory complication avoided at 28 days. RESULTS The trial included 10,495 patient admissions from 18 paediatric intensive care units from 5 February 2018 to 14 October 2019. In children with anticipated prolonged ventilation (n = 8843 admissions: control, n = 4155; intervention, n = 4688), the intervention resulted in a significantly shorter time to successful extubation [cluster and time-adjusted median difference -6.1 hours (interquartile range -8.2 to -5.3 hours); adjusted hazard ratio 1.11, 95% confidence interval 1.02 to 1.20; p = 0.02] and a higher incidence of successful extubation (adjusted relative risk 1.01, 95% confidence interval 1.00 to 1.02; p = 0.03) and unplanned extubation (adjusted relative risk 1.62, 95% confidence interval 1.05 to 2.51; p = 0.03), but not reintubation (adjusted relative risk 1.10, 95% confidence interval 0.89 to 1.36; p = 0.38). In the intervention period, the use of post-extubation non-invasive ventilation was significantly higher (adjusted relative risk 1.22, 95% confidence interval 1.01 to 1.49; p = 0.04), with no evidence of a difference in intensive care length of stay or other harms, but hospital length of stay was longer (adjusted hazard ratio 0.89, 95% confidence interval 0.81 to 0.97; p = 0.01). Findings for all children were broadly similar. The control period was associated with lower, but not statistically significantly lower, total costs (cost difference, mean £929.05, 95% confidence interval -£516.54 to £2374.64) and significantly fewer respiratory complications avoided (mean difference -0.10, 95% confidence interval -0.16 to -0.03). LIMITATIONS The unblinded intervention assignment may have resulted in performance or detection bias. It was not possible to determine which components were primarily responsible for the observed effect. Treatment effect in a more homogeneous group remains to be determined. CONCLUSIONS The intervention resulted in a statistically significant small reduction in time to first successful extubation; thus, the clinical importance of the effect size is uncertain. FUTURE WORK Future work should explore intervention sustainability and effects of the intervention in other paediatric populations. TRIAL REGISTRATION This trial is registered as ISRCTN16998143.

Abstract
Comfort of the critically unwell pediatric patient is paramount to ensuring good outcomes. Analgesia-based, multimodal sedative approaches are the foundation for comfort, whereby pain is addressed first and then sedation titrated to a predefined target based on the goals of care. Given the heterogeneity of patients within the pediatric critical care population, the approach must be individualized based on the age and developmental stage of the child, physiologic status, and degree of invasive treatment required. In both the adult and pediatric intensive care unit (PICU), sedation titration is practiced as standard of care to meet therapeutic goals with a focus on facilitating early rehabilitation and extubation while avoiding under- and over-sedation. Sedation protocols have been developed as methods to reduce variability and optimize goal-directed therapy. Components of a sedation protocol include routine analgesia and sedation scoring with validated tools at specified intervals and a predefined algorithm that allows the titration of analgesia and sedation based on those assessments. Sedation protocols are designed to improve communication and documentation of sedation goals while also empowering the bedside team to respond rapidly to changes in a patient's clinical status. Previously it was thought that sedation protocols would consistently reduce duration of mechanical ventilation (MV) and length of stay (LOS) for patients in the PICU, however, this has not been the case. Nonetheless, introduction of sedation protocols has provided several benefits, including: (I) reduction in benzodiazepine usage; (II) improvements in interprofessional communication surrounding sedation goals and management of sedation goals; and (III) reductions in iatrogenic withdrawal symptoms. Successful implementation of sedation protocols requires passionate clinical champions and a robust implementation, education, and sustainability plan. Emerging evidence suggests that sedation protocols as part of a bundle of quality improvement initiatives will form the basis of future studies to improve short- and long-term outcomes after PICU discharge. In this review, we aim to define sedation protocols in the context of pediatric critical care and highlight important considerations for clinical practice and research.

Abstract
IMPORTANCE There is limited evidence on the optimal strategy for liberating infants and children from invasive mechanical ventilation in the pediatric intensive care unit. OBJECTIVE To determine if a sedation and ventilator liberation protocol intervention reduces the duration of invasive mechanical ventilation in infants and children anticipated to require prolonged mechanical ventilation. DESIGN, SETTING, AND PARTICIPANTS A pragmatic multicenter, stepped-wedge, cluster randomized clinical trial was conducted that included 17 hospital sites (18 pediatric intensive care units) in the UK sequentially randomized from usual care to the protocol intervention. From February 2018 to October 2019, 8843 critically ill infants and children anticipated to require prolonged mechanical ventilation were recruited. The last date of follow-up was November 11, 2019. INTERVENTIONS Pediatric intensive care units provided usual care (n = 4155 infants and children) or a sedation and ventilator liberation protocol intervention (n = 4688 infants and children) that consisted of assessment of sedation level, daily screening for readiness to undertake a spontaneous breathing trial, a spontaneous breathing trial to test ventilator liberation potential, and daily rounds to review sedation and readiness screening and set patient-relevant targets. MAIN OUTCOMES AND MEASURES The primary outcome was the duration of invasive mechanical ventilation from initiation of ventilation until the first successful extubation. The primary estimate of the treatment effect was a hazard ratio (with a 95% CI) adjusted for calendar time and cluster (hospital site) for infants and children anticipated to require prolonged mechanical ventilation. RESULTS There were a total of 8843 infants and children (median age, 8 months [interquartile range, 1 to 46 months]; 42% were female) who completed the trial. There was a significantly shorter median time to successful extubation for the protocol intervention compared with usual care (64.8 hours vs 66.2 hours, respectively; adjusted median difference, -6.1 hours [interquartile range, -8.2 to -5.3 hours]; adjusted hazard ratio, 1.11 [95% CI, 1.02 to 1.20], P = .02). The serious adverse event of hypoxia occurred in 9 (0.2%) infants and children for the protocol intervention vs 11 (0.3%) for usual care; nonvascular device dislodgement occurred in 2 (0.04%) vs 7 (0.1%), respectively. CONCLUSIONS AND RELEVANCE Among infants and children anticipated to require prolonged mechanical ventilation, a sedation and ventilator liberation protocol intervention compared with usual care resulted in a statistically significant reduction in time to first successful extubation. However, the clinical importance of the effect size is uncertain. TRIAL REGISTRATION isrctn.org Identifier: ISRCTN16998143.

Abstract
OBJECTIVES There is limited evidence on the impact of protocolized ventilator weaning in pediatric acute respiratory distress syndrome, despite utilization in clinical trials and clinical care. We aimed to determine whether protocolized ventilator weaning shortens mechanical ventilation duration and PICU length of stay in pediatric acute respiratory distress syndrome survivors. DESIGN Secondary analysis of a prospective pediatric acute respiratory distress syndrome (Berlin definition) cohort from July 2011 to June 2019 analyzed using interrupted time series analysis pre- and postimplementations of a ventilator-weaning pathway. We compared duration of invasive ventilation and PICU length of stay in survivors before and after implementation of a ventilator-weaning pathway. We excluded PICU nonsurvivors and subjects with greater than 100 ventilator days. SETTING Large academic tertiary-care PICU. PATIENTS Children with acute respiratory distress syndrome who survived to PICU discharge with less than or equal to 100 days of invasive mechanical ventilation. INTERVENTIONS Implementation of a ventilator-weaning pathway on May 2016. MEASUREMENTS AND MAIN RESULTS Of 723 children with acute respiratory distress syndrome, 132 subjects died and six subjects with ventilation greater than 100 days were excluded. Of the remaining 585 subjects, 375 subjects had acute respiratory distress syndrome prior to pathway intervention and 210 after. Patients in the preintervention epoch were younger, more likely to have infectious acute respiratory distress syndrome, and had increased use of alternative ventilator modes. Pathway adoption was rapid and sustained. Controlling for temporality, pathway implementation was associated with a decrease of a median 3.6 ventilator days (95% CI, -5.4 to -1.7; p < 0.001). There was no change in the reintubation rates. Results were robust to multiple sensitivity analyses adjusting for confounders. CONCLUSIONS Ventilator-weaning pathway implementation shortened invasive ventilation duration in pediatric acute respiratory distress syndrome survivors with no change in reintubation. The effect size of this intervention was comparable with those targeted in acute respiratory distress syndrome trials.

Abstract
INTRODUCTION Weaning from ventilation is a complex process involving several stages that include recognition of patient readiness to begin the weaning process, steps to reduce ventilation while optimising sedation in order not to induce distress and removing the endotracheal tube. Delay at any stage can prolong the duration of mechanical ventilation. We developed a multicomponent intervention targeted at helping clinicians to safely expedite this process and minimise the harms associated with unnecessary mechanical ventilation. METHODS AND ANALYSIS This is a 20-month cluster randomised stepped wedge clinical and cost-effectiveness trial with an internal pilot and a process evaluation. It is being conducted in 18 paediatric intensive care units in the UK to evaluate a protocol-based intervention for reducing the duration of invasive mechanical ventilation. Following an initial 8-week baseline data collection period in all sites, one site will be randomly chosen to transition to the intervention every 4 weeks and will start an 8-week training period after which it will continue the intervention for the remaining duration of the study. We aim to recruit approximately 10 000 patients. The primary analysis will compare data from before the training (control) with that from after the training (intervention) in each site. Full details of the analyses will be in the statistical analysis plan. ETHICS AND DISSEMINATION This protocol was reviewed and approved by NRES Committee East Midlands-Nottingham 1 Research Ethics Committee (reference: 17/EM/0301). All sites started patient recruitment on 5 February 2018 before randomisation in April 2018. Results will be disseminated in 2020. The results will be presented at national and international conferences and published in peer-reviewed medical journals. TRIAL REGISTRATION NUMBER ISRCTN16998143.

Role of physical therapists in the weaning and extubation procedures of pediatric and neonatal intensive care units: a survey. Braz J Phys Ther 2018; 23:317-323. [PMID: 30249437 DOI: 10.1016/j.bjpt.2018.08.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2018] [Revised: 05/09/2018] [Accepted: 08/22/2018] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND Weaning a patient from mechanical ventilation is a complex procedure that involves clinical and contextual aspects. Mechanical ventilation also depends on the characteristics of health professionals who work in intensive care. OBJECTIVE This study described the organizational aspects associated with the physical therapist's performance in the weaning procedure from mechanical ventilation and extubation in neonatal, pediatric and mixed (neonatal and pediatric) intensive care units in Brazil. METHODS In order to identify the existing intensive care units in Brazil, data from the National Health Facilities Census was used to enable the researchers to obtain information about registered units. A cross-sectional survey was carried out by sending an electronic questionnaire to 298 neonatal, pediatric and mixed intensive care units in Brazil. RESULTS This study assessed questionnaires from 146 intensive care units (49.3% neonatal, 35.6% pediatric and 15.1% mixed). A total of 57.5% of these units applied mechanical ventilation weaning protocols, and a physical therapist frequently conducted this procedure (66.7%). However, the clinician responsible for conducting the weaning and deciding when to do extubation varied regardless of ICU patient age profile. Regardless of the type of hospital or the type of units, most of these had a dedicated physical therapist. However, physical therapy care 24h/7 days per week was predominantly in pediatric intensive care units (56.0%), and in public hospitals (45.9%). Moreover, when the physical therapist was available 24h/7 days per week, (s)he was responsible for the mechanical ventilation extubation decision and patients were successfully extubated on the first attempt. CONCLUSION In this survey, intensive care units using physical therapy assistance 24h/7 days per week were associated with the use of a mechanical ventilation weaning protocol, an extubation decision and success commonly on the first attempt of extubation.

Abstract
Abstract
Objective
This review addresses sedation management on paediatric intensive care units and possible gaps in the knowledge of optimal sedation strategies. We present an overview of the commonly used sedatives and their pharmacokinetic and pharmacodynamic considerations in children, as well as the ongoing studies in this field. Also, sedation guidelines and current sedation strategies and assessment methods are addressed.
Key findings
This review shows that evidence and pharmacokinetic data are scarce, but fortunately, there is an active research scene with promising new PK and PD data of sedatives in children using new study designs with application of advanced laboratory methods and modelling. The lack of evidence is increasingly being recognized by authorities and legislative offices such as the US Food and Drug Administration (FDA) and European Medicines Agency (EMA).
Conclusion
The population in question is very heterogeneous and this overview can aid clinicians and researchers in moving from practice-based sedation management towards more evidence- or model-based practice. Still, paediatric sedation management can be improved in other ways than pharmacology only, so future research should aim on sedation assessment and implementation strategies of protocolized sedation as well.

Tume LN, Preston J, Blackwood B. Parents' and young people's involvement in designing a trial of ventilator weaning. Nurs Crit Care 2015; 21:e10-8. [PMID: 26486094 DOI: 10.1111/nicc.12221] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2015] [Revised: 08/04/2015] [Accepted: 09/05/2015] [Indexed: 01/05/2023]
Abstract
Consulting with users is considered best practice and is highly recommended in designing new trials. As part of our feasibility work, we undertook a consultation exercise with parents, ex-patients and young people prior to designing a trial of protocol-based ventilator weaning. Our aims were to (1) ascertain views on the relevance and importance of the trial; (2) determine the important parent/patient outcome measures; and (3) ascertain views on informed consent in a cluster randomized controlled trial. We conducted audio-recorded face-to-face, telephone and focus group interviews with parents and young people. Data were content analysed to generate information to address our specific consultation objectives. The setting was the north-western region of England. A total of 16 participants were interviewed: 2 parents of paediatric intensive care unit (PICU) survivors; 1 PICU survivor; and 13 young people from the former Medicines for Children Research Network. The trial objectives were deemed important and relevant, and participants considered the most important outcome measure to be the length of time on ventilation. Parents and young people did not consider written informed consent to be a necessary requirement in the context of this trial, rather awareness of unit participation in the trial was important with the opportunity of opting out of data collection. This consultation provided useful, pragmatic insights to inform trial design. We encountered significant challenges in recruiting parents and young people for this consultation exercise, and novel recruitment methods need to be considered for future work in this field. Patient and public involvement is essential to ensure that future trials answer parent-relevant questions and have meaningful outcome measures, as well as involving parents and young people in the general development of health care services.
