Recommendations for mechanical ventilation of critically ill children from the Paediatric Mechanical Ventilation Consensus Conference (PEMVECC)

Purpose

Much of the common practice in paediatric mechanical ventilation is based on personal experiences and what paediatric critical care practitioners have adopted from adult and neonatal experience. This presents a barrier to planning and interpretation of clinical trials on the use of specific and targeted interventions. We aim to establish a European consensus guideline on mechanical ventilation of critically children.

Methods

The European Society for Paediatric and Neonatal Intensive Care initiated a consensus conference of international European experts in paediatric mechanical ventilation to provide recommendations using the Research and Development/University of California, Los Angeles, appropriateness method. An electronic literature search in PubMed and EMBASE was performed using a combination of medical subject heading terms and text words related to mechanical ventilation and disease-specific terms.

Results

The Paediatric Mechanical Ventilation Consensus Conference (PEMVECC) consisted of a panel of 15 experts who developed and voted on 152 recommendations related to the following topics: (1) general recommendations, (2) monitoring, (3) targets of oxygenation and ventilation, (4) supportive measures, (5) weaning and extubation readiness, (6) normal lungs, (7) obstructive diseases, (8) restrictive diseases, (9) mixed diseases, (10) chronically ventilated patients, (11) cardiac patients and (12) lung hypoplasia syndromes. There were 142 (93.4%) recommendations with “strong agreement”. The final iteration of the recommendations had none with equipoise or disagreement.

Conclusions

These recommendations should help to harmonise the approach to paediatric mechanical ventilation and can be proposed as a standard-of-care applicable in daily clinical practice and clinical research.

Elective nasal continuous positive airway pressure to support respiration after prolonged ventilation in infants after congenital cardiac surgery

Background:

We sought to compare the effectiveness of oxygen (O₂) treatment administered by an O₂ mask and nasal continuous positive airway pressure (NCPAP) in infants after congenital cardiac surgery.

Methods:

In this retrospective observational study, 54 infants undergoing corrective cardiac surgery were enrolled. According to the anesthesiologist's preference, the patients ventilated for more than 48 h were either put on NCPAP or O₂ mask immediately after extubation. From pre-extubation to 24 h after treatment, arterial blood gas and hemodynamic data were measured.

Results:

After 24 h of NCPAP institution, the patients showed a significant improvement in oxygenation compared to O₂ mask group. Respiratory rate (per minute) decreased from 31.67 ± 4.55 to 24.31 ± 3.69 (P < 0.0001), PO₂ (mmHg) increased from 112.12 ± 22.83 to 185.74 ± 14.81 (P < 0.0001), and PCO₂ (mmHg) decreased from 42.88 ± 5.01 to 37.00 ± 7.22 (P < 0.0076) in patients on NCPAP. In this group, mean pediatric cardiac surgical Intensive Care Unit (PCSICU) stay was 4.72 ± 1.60 days, with only 2 (11.11%) patients requiring re-intubation.

Conclusion:

NCPAP can be used safely and effectively in infants undergoing congenital cardiac surgery to improve oxygenation/ventilation. It also reduces the work of breathing, PCSICU stay, and may reduce the likelihood of re-intubation.

Non-invasive ventilation is useful in paediatric intensive care units if children are appropriately selected and carefully monitored

Non-invasive ventilation (NIV) is commonly used in paediatric intensive care units (PICUs) for respiratory failure. This review aims to improve paediatricians' understanding of NIV, by specifying technical or practical considerations, giving advice about selecting patients and presenting pertinent published data about NIV in different circumstances.

CONCLUSION

NIV is useful in PICUs if children are appropriately selected and carefully monitored. Technological advances and future clinical research will improve its use and success rate in PICU.

Noninvasive positive pressure ventilation in critically ill children with cardiac disease

Noninvasive ventilation is effective in respiratory failure from various etiologies. This study aimed to analyze the efficacy of noninvasive positive pressure ventilation (NPPV) in pediatric cardiac patients. NPPV was used (1) as an alternative means of respiratory support in patients with hypoxemic or hypercarbic respiratory failure or with signs of respiratory distress that were considered to require intubation; or (2) as a preventive measure in patients with high risk for extubation failure. Between 2008 and 2011, there were 107 episodes of NPPV use in 82 patients. Their median age was 57 days (range 1 day to 18 years), and weight was 4.1 kg (range 1.7-68). Within the first hour of NPPV, partial pressure of carbon dioxide/fraction of inspired oxygen (PaO2/FiO2) was significantly increased, and arterial pCO2, and respiratory rate were decreased. This decrease in respiratory rate and increase in PaO 2/FiO2 continued during the first 24 h of therapy, and pCO2 was decreased during the first 6 h. In 59.8% of cases, NPPV was successfully used without the need for tracheal intubation. The Aristotle Basic Complexity score, presence of infection, residual cardiac defect, and pH <7.36 in the first hour were independent predictors of NPPV failure. We conclude that NPPV improved oxygenation and decreased respiratory effort in pediatric cardiac patients, 59.8% of whom eventually did not receive intubation. A high-complexity surgical score, presence of infection, residual cardiac defect, and pH <7.36 in the first hour are predictors of NPPV failure, which occurs in most patients >24 h after the onset of therapy.
