Efficacy and predictors of success of noninvasive ventilation for prevention of extubation failure in critically ill children with heart disease

Use of high-flow nasal cannula versus other noninvasive ventilation techniques or conventional oxygen therapy for respiratory support following pediatric cardiac surgery: A systematic review and meta-analysis

INTRODUCTION

Noninvasive respiratory support may be provided to decrease the risk of postextubation failure following surgery. Despite these efforts, approximately 3%-27% of infants and children still experience respiratory failure after tracheal extubation following cardiac surgery. This systematic review evaluates studies comparing the efficacy of high-flow nasal cannula to conventional oxygen therapy such as nasal cannula and other noninvasive ventilation techniques in preventing postextubation failure in this patient population.

METHODS

A systematic and comprehensive search was conducted in major databases including MEDLINE, EMBASE, Web of Science, and Central. The search encompassed articles focusing on the prophylactic use of high-flow nasal cannula following tracheal extubation in pediatric patients undergoing cardiac surgery for congenital heart disease. The inclusion criteria for this review consisted of randomized clinical trials as well as observational, cohort, and case-control studies.

RESULTS

A total of 1295 studies were screened and 12 studies met the inclusion criteria. These 12 studies included a total of 1565 children, classified into three groups: seven studies compared high-flow nasal cannula to noninvasive ventilation techniques, four studies compared high-flow nasal cannula to conventional oxygen therapy, and one observational single-arm study explored the use of high-flow nasal cannula with no control group. There was no significant difference in the incidence of tracheal reintubation between high-flow nasal cannula and conventional oxygen therapy (risk ratio [RR] = 0.67, 95% confidence interval [CI]: 0.24-1.90, p = .46). However, there was a lower incidence of tracheal reintubation in patients who were extubated to high-flow nasal cannula versus those extubated to noninvasive ventilation techniques (RR = 0.45, 95% CI: 0.32-0.63, p < .01). The high-flow nasal cannula group also demonstrated a lower mortality rate compared to the noninvasive ventilation techniques group (RR = 0.31, 95% CI: 0.16-0.61, p < .01) as well as a shorter postoperative length of stay (mean difference = -8.76 days, 95% CI: -13.08 to -4.45, p < .01) and shorter intensive care length of stay (mean difference = -4.63 days, 95% CI: -9.16 to -0.11, p = .04).

CONCLUSION

High-flow nasal cannula is more effective in reducing the rate of postextubation failure compared to other forms of noninvasive ventilation techniques following surgery for congenital heart disease in pediatric-aged patients. high-flow nasal cannula is also associated with lower mortality rates and shorter length of stay. However, when comparing high-flow nasal cannula to conventional oxygen therapy, the findings were inconclusive primarily due to a limited number of scientific studies available on this specific comparison. Future study is needed to further define the benefit of high-flow nasal cannula compared to conventional oxygen therapy and various types of noninvasive ventilation techniques.

Risk Factors for Extubation Failure After Pediatric Cardiac Surgery and Impact on Outcomes: A Multicenter Analysis

IMPORTANCE

Extubation failure (EF) after pediatric cardiac surgery is associated with increased morbidity and mortality.

OBJECTIVES

We sought to describe the risk factors associated with early (< 48 hr) and late (48 hr ≤ 168 hr) EF after pediatric cardiac surgery and the clinical implications of these two types of EF.

DESIGN SETTING AND PARTICIPANTS

Retrospective cohort study using prospectively collected clinical data for the Pediatric Cardiac Critical Care Consortium (PC4) Registry. Pediatric patients undergoing Society of Thoracic Surgeons benchmark operation or heart transplant between 2013 and 2018 available in the PC4 Registry were included.

MAIN OUTCOMES AND MEASURES

We analyzed demographics and risk factors associated with EFs (primary outcome) including by type of surgery. We identified potentially modifiable risk factors. Clinical outcomes of mortality and length of stay (LOS) were reported.

RESULTS

Overall 18,278 extubations were analyzed. Unplanned extubations were excluded from the analysis. The rate of early EF was 5.2% (948) and late EF was 2.5% (461). Cardiopulmonary bypass time, ventilator duration, airway anomaly, genetic abnormalities, pleural effusion, and diaphragm paralysis contributed to both early and late EF. Extubation during day remote from shift change and nasotracheal route of initial intubation was associated with decreased risk of early EF. Extubation in the operating room was associated with an increased risk of early EF but with decreased risk of late EF. Across all operations except arterial switch, EF portrayed an increased burden of LOS and mortality.

CONCLUSION AND RELEVANCE

Both early and late EF are associated with significant increase in LOS and mortality. Study provides potential benchmarking data by type of surgery. Modifiable risk factors such as route of intubation, time of extubation as well as treatment of potential contributors such as diaphragm paralysis or pleural effusion can serve as focus areas for reducing EFs.

Pulmonary and clinical outcomes of patients with severe rigid scoliosis and type I respiratory failure treated with halo-pelvic distraction

BACKGROUND

The severe rigid scoliosis patients with type I respiratory failure could not tolerate complicated corrective surgery. Preoperative halo-pelvic distraction (HPD) is used to reduce the curve magnitude and improve the pulmonary function before surgery. The present study aimed to retrospectively analyze the pulmonary and clinical outcomes of preoperative HPD in severe rigid spinal deformity with type I respiratory failure.

METHODS

Eighteen cases of severe rigid scoliosis and type I respiratory failure treated with preoperative HPD and corrective surgery for spinal deformity between 2016 and 2018 were retrospectively reviewed. Patient demographics, major coronal curve and kyphosis, correction rates, heights, pulmonary function, distraction time, and postoperative neurological complications were recorded for all cases.

RESULTS

The averaged duration of distraction was 9.1 ± 2.3 months. The coronal curve was corrected from 168° ± 14° to 58° ± 11° at the end of HPD. The kyphosis curve reduced from 151° ± 29° to 65° ± 10°. Meanwhile, the mean stand body height increased by 23.9 ± 5.3 cm. Significantly increased mean FVC (1.52 ± 0.43 L vs. 0.95 ± 0.44 L) and improved percent-predicted values for FVC (37 ± 10% vs. 23 ± 9%) were observed after HPD. The pressure of oxygen (PaO2) increased from 54.5 ± 2.0 to 84.8 ± 4.7 mmHg. Scoliosis and kyphosis curve, respectively, averaged 48 ± 8°and 30 ± 14° after final fusion and instrumentation, with a mean correction of 71% and 80%, respectively. No severe complication occurred during the distraction.

CONCLUSIONS

HPD may be useful for severe rigid scoliosis patients with type I respiratory failure. Pulmonary functions in patients with severe rigid scoliosis can be significantly improved by HPD. They are then better able to tolerate complicated corrective surgery.

Extubation to High-Flow Nasal Cannula in Infants Following Cardiac Surgery: A Retrospective Cohort Study

High-flow nasal cannula (HFNC) therapy is commonly used in the pediatric intensive care unit (PICU) for postextubation respiratory support. This hypothesis-generating retrospective cohort study aimed to compare postextubation PICU length of stay in infants extubated to HFNC and low flow oxygen (LF) in PICU following cardiac surgery. Of 136 infants (newborn to 1 year) who were intubated and mechanically ventilated in PICU following cardiac surgery, 72 (53%) were extubated to HFNC and 64 (47%) to LF. Compared with patients extubated to LF, those extubated to HFNC had significantly longer durations of cardiopulmonary bypass (152 vs. 109 minutes; p  = 0.002), aortic cross-clamp (90 vs. 63 minutes; p  = 0.003), and invasive mechanical ventilation (3.2 vs. 1.6 days; p  < 0.001), although demographic and preoperative clinical variables were similar. No significant difference was observed in postextubation PICU length of stay between HFNC and LF groups in unadjusted analysis (3.3 vs. 2.6 days, respectively; p  = 0.19) and after controlling for potential confounding variables (F [1,125] = 0.17, p  = 0.68, R 2  = 0.16). Escalation of therapy was similar between HFNC and LF groups (8.3 vs. 14.1%; p  = 0.41). HFNC was effective as rescue therapy for six patients in the LF group requiring escalation of therapy. Need for reintubation was similar between HFNC and LF groups (8.3 vs. 4.7%; p  = 0.5). Although extubation to HFNC was associated with a trend toward longer postextubation PICU length of stay and was successfully used as rescue therapy for several infants extubated to LF, our results must be interpreted with caution given the limitations of our study.

Long-term non-invasive ventilation in children: Transition from hospital to home

Long-term non-invasive ventilation (NIV) is an accepted therapy for sleep-related respiratory disorders and respiratory insufficiency or failure. Increase in the use of long-term NIV may, in part, be driven by an increase in the number of children surviving critical illness with comorbidities. As a result, some children start on long-term NIV as part of transitioning from hospital to home. NIV may be used in acute illness to avoid intubation, facilitate extubation or support tracheostomy decannulation, and to avoid the need for a tracheostomy for long-term invasive ventilation. The decision about whether long-term NIV is appropriate for an individual child and their family needs to be made with care. Preparing for transition from the hospital to home involves understanding how NIV equipment is obtained and set-up, education and training for parents/caregivers, and arranging a plan for clinical follow-up. While planning for these transitions is challenging, the goals of a shorter time in hospital and a child living well at home with their family are important.

Efficacy of prophylactic high-flow nasal cannula therapy for postoperative pulmonary complications after pediatric cardiac surgery: a prospective single-arm study

PURPOSE

This study investigated the incidence of postoperative pulmonary complications (PPC) when high-flow nasal cannula therapy (HFNC) is used prophylactically after pediatric cardiac surgery, and evaluated its efficacy.

METHODS

This was a single-arm prospective interventional study that was conducted in a tertiary teaching hospital with eight beds in the pediatric cardiac ICU after approval by the Ethics Committee. One-hundred children under the age of 48 months who were scheduled for cardiac surgery for congenital heart disease were recruited. HFNC was used for 24 h after extubation at a 2 L/kg/min flow rate. The primary outcome was the incidence of PPC within 48 h after extubation. PPC was defined as atelectasis and acute respiratory failure meeting certain criteria. We considered prophylactic HFNC as effective if the prevalence of PPC was < 10%, based on previous reports of reintubation rates of 6%-9% after pediatric cardiac surgery.

RESULTS

A total of 91 patients were finally included in the analysis. The incidence of PPC within 48 h after extubation was 18.7%, whereas atelectasis was observed in 13.2%, and acute respiratory failure in 8.8%. Reintubation rate within 48 h after extubation was 0%.

CONCLUSIONS

We found the incidence of PPC with prophylactic HFNC after planned extubation after pediatric cardiac surgery. However, the incidence was > 10%; therefore, we could not demonstrate its efficacy in this single-arm study. Further studies are needed to investigate whether the HFNC could be adapted as first-line oxygen therapy after pediatric cardiac surgery.

A comparison of high-flow nasal cannula versus non-invasive positive pressure ventilation for respiratory support in infants following cardiac surgery

BACKGROUND

Following cardiac surgery, infants often remain endotracheally intubated upon arrival to the cardiac ICU. High-flow nasal cannula and non-invasive positive pressure ventilation are used to support patients following extubation. There are limited data on the superiority of either mode to prevent extubation failure.

METHODS

We conducted a single-centre retrospective study for infants (<1 year) and/or <10 kg who underwent cardiac surgery between 3/2019-3/2020. Data included patient and clinical characteristics and operative variables. The study aimed to compare high-flow nasal cannula versus non-invasive positive pressure ventilation following extubation and their association with extubation failure. Secondarily, we examined risk factors associated with extubation failure.

RESULTS

There were 424 patients who met inclusion criteria, 320 (75%) were extubated to high-flow nasal cannula, 104 (25%) to non-invasive positive pressure ventilation, and 64 patients (15%) failed extubation. The high-flow nasal cannula group had lower rates of extubation failure (11%, versus 29%, p = 0.001). Infants failing extubation were younger and had higher STAT score (p < 0.05). Compared to high-flow nasal cannula, non-invasive positive pressure ventilation patients were at 3.30 times higher odds of failing extubation after adjusting for patient factors (p < 0.0001).

CONCLUSIONS

Extubation failure after cardiac surgery occurs in smaller, younger infants, and those with higher risk surgical procedures. Patients extubated to non-invasive positive pressure ventilation had 3.30 higher odds to fail extubation than patients extubated to high-flow nasal cannula. The optimal mode of respiratory support in this patient population is unknown.

Acute Cardiac Care for Neonatal Heart Disease

This manuscript is one component of a larger series of articles produced by the Neonatal Cardiac Care Collaborative that are published in this supplement of Pediatrics. In this review article, we summarize the contemporary physiologic principles, evaluation, and management of acute care issues for neonates with complex congenital heart disease. A multidisciplinary team of authors was created by the Collaborative's Executive Committee. The authors developed a detailed outline of the manuscript, and small teams of authors were assigned to draft specific sections. The authors reviewed the literature, with a focus on original manuscripts published in the last decade, and drafted preliminary content and recommendations. All authors subsequently reviewed and edited the entire manuscript until a consensus was achieved. Topics addressed include cardiopulmonary interactions, the pathophysiology of and strategies to minimize the development of ventilator-induced low cardiac output syndrome, common postoperative physiologies, perioperative bleeding and coagulation, and common postoperative complications.

Comparison of high flow oxygen therapy versus noninvasive mechanical ventilation for successful weaning from invasive ventilation in children: An observational study

Post-extubation respiratory failure is associated with a poor prognosis due to increased ventilator-associated pneumonia, and longer length of stay in the ICU and hospital. In this study, we aimed to evaluate the efficacy of high-flow nasal cannula (HFNC) and noninvasive mechanical ventilation (NIMV) on extubation success in children. A total of 48 patients, aged between 1 month and 18 years, who were weaned to either NIMV or HFNC were included. Patients who had tracheostomy or were not weaned and underwent unplanned extubation were excluded. Age, gender, anthropometric parameters, Pediatric Risk of Mortality and Pediatric Logistic Organ Dysfunction scores, oxygenation index, mechanical ventilation length of stay (LOS), HFNC/NIMV LOS, Modified Downes-Silverman score (MDS), and venous blood gas parameters, pediatric intensive care unit (PICU) LOS were recorded. 24 patients were extubated to NIMV, and 24 patients to HFNC. HFNC LOS and NIMV LOS were similar (P = .621). The failure rates at the 48th hour of HFNC and NIMV were 33% (n = 8), and 33% respectively (n = 8) (P = 1.0). PICU LOS and mortality rate was also similar (P = .06, P = .312 respectively). MDS decreased significantly in both groups (P < .001, P = .02 respectively). Changes in blood gas parameters and MDS within the first 48-hour of device application were similar between the 2 groups. HFNC is not inferior to NIMV in patients with extubation difficulty or those expected to have such difficulty in terms of treatment success, PICU LOS, and mortality. Therefore, HFNC appears to be a weaning technique alternative to NIMV after extubation.

Developing an Extubation strategy for the difficult pediatric airway-Who, when, why, where, and how?

Comprehensive airway management of the pediatric patient with a difficult airway requires a plan for the transition back to a patent and protected airway. Multiple techniques are available to manage the periextubation period. Equally important is performing a comprehensive risk assessment and developing a strategy that optimizes the likelihood of safe extubation. This includes team-focused communication of the desired goals, critical steps in the process, and potential responses in the case of failed extubation. This review summarizes extubation of pediatric patients with difficult airways along with one suggested framework to manage this challenging period.

Associations With Extubation Failure and Predictive Value of Risk Analytics Algorithms With Extubation Readiness Tests Following Congenital Cardiac Surgery

OBJECTIVES

Extubation failure is associated with morbidity and mortality in children following cardiac surgery. Current extubation readiness tests (ERT) do not consider the nonrespiratory support provided by mechanical ventilation (MV) for children with congenital heart disease. We aimed to identify factors associated with extubation failure in children following cardiac surgery and assess the performance of two risk analytics algorithms for patients undergoing an ERT.

DESIGN

Retrospective cohort study.

SETTING

CICU at a tertiary-care children's hospital.

PATIENTS

Children receiving MV greater than 48 hours following cardiac surgery between January 1, 2017, and December 31, 2019.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Six hundred fifty encounters were analyzed with 49 occurrences (8%) of reintubation. Extubation failure occurred most frequently within 6 hours of extubation. On multivariable analysis, younger age (per each 3-mo decrease: odds ratio [OR], 1.06; 95% CI, 1.001-1.12), male sex (OR, 2.02; 95% CI, 1.03-3.97), Society of Thoracic Surgery-European Association for Cardiothoracic Surgery category 5 procedure (p equals to 0.005), and preoperative respiratory support (OR, 2.08; 95% CI, 1.09-3.95) were independently associated with unplanned reintubation. Our institutional ERT had low sensitivity to identify patients at risk for reintubation (23.8%; 95% CI, 9.7-47.6%). The addition of the inadequate delivery of oxygen (IDO2) index to the ERT increased the sensitivity by 19.0% (95% CI, -2.5 to 40.7%; p = 0.05), but the sensitivity remained low and the accuracy of the test dropped by 8.9% (95% CI, 4.7-13.1%; p < 0.01).

CONCLUSIONS

Preoperative respiratory support, younger age, and more complex operations are associated with postoperative extubation failure. IDO2 and IVCO2 provide unique cardiorespiratory monitoring parameters during ERTs but require further investigation before being used in clinical evaluation for extubation failure.

The Decision to Extubate: The Association Between Clinician Impressions and Objective Extubation Readiness Criteria in a Pediatric Intensive Care Unit

Objective Objective tools such as spontaneous breathing trials (SBT) aim to identify patients ready for extubation and shorten the length of mechanical ventilation (MV). Despite passing an SBT, patients sometimes are not extubated based on clinicians' subjective impressions. In this article, we explored the factors that influence the decision to extubate among pediatric intensivists and their association with objective criteria.

Design This is a single-center prospective observational study.

Setting This study was conducted in an academic, multidisciplinary 20-bed pediatric intensive care unit (PICU).

Patients The study group involves mechanically ventilated, orally intubated patients admitted to the PICU from January 1 to June 30, 2019.

Measurements and Main Results Objective clinical data were collected for 650 MV days. Attending surveys about extubation readiness were completed for 419 (64.5%) MV days and 63 extubation events. Extubation occurred on 42% of days after passing an SBT. The primary reasons patients who passed an SBT were not extubated on days were unresolved lung pathology (66.6%) and fluid overload (37.6%). On days without extubation, there was no association between a specific reason for not extubating and SBT result (p > 0.05).

Conclusions In this single-center study, the decision to extubate was not strongly associated with passing an SBT, indicating that clinician impressions, namely unresolved lung pathology and fluid overload, outweighed objective measures for determining extubation readiness. To mitigate morbidities and costs associated with unnecessarily prolonged intubations, a better-defined extubation readiness process is needed to guide the decision to extubate in the pediatric population.

Volume-guarantee vs. pressure-limited ventilation in evolving bronchopulmonary dysplasia

INTRODUCTION

Extremely premature infants are at high risk for developing bronchopulmonary dysplasia (BPD). While noninvasive support is preferred, they may require ventilator support. Although volume-targeted ventilation (VTV) has been shown to be beneficial in preventing BPD, no data exists to guide ventilator management of infants with evolving BPD. Thus, clinicians employ a host of ventilator strategies, traditionally time-cycled pressure-limited ventilation (PLV) and more recently volume-guarantee ventilation (VGV) (a form of VTV). In this study, we sought to test the hypothesis that use of VGV in evolving BPD is associated with improved clinical and pulmonary outcomes when compared with PLV.

DESIGN

Single-center, retrospective cohort review of premature infants born less than 28 weeks inborn to a Level 4 NICU from January 2015 to December 2020. Data abstracted included demographics, maternal and birth data, and ventilator data until death or discharge. Exposure to either VGV or PLV was also examined, including ventilator "dose" (number of time points from DOL 14, 21 and 28 the patient was on that particular ventilator) during the period of evolving BPD.

RESULTS

Of a total of 471 patients with ventilation data available on DOL 14, 268 were not ventilated and 203 were ventilated. PLV at DOL 21 and 28 was associated with significantly higher risk of BPD and the composite outcome of BPD or death before 36 weeks compared to VGV. Both increasing VGV and PLV doses were significantly associated with higher odds of BPD and the composite outcome. For each additional time point of VGV and PLV exposure, the predicted length of stay (LOS) increased by 15.3 days (p < 0.001) and 28.8 days (p < 0.001), respectively.

DISCUSSION

Our study demonstrates the association of use of VGV at DOL 21 and 28 with decreased risk of BPD compared to use of PLV. Prospective trials are needed to further delineate the most effective ventilatory modality for this population with "evolving" BPD.

Utilisation of RAM cannula for non-invasive respiratory support for infants in the cardiac ICU

BACKGROUND

Children with CHD carry an additional burden of pulmonary insufficiency, often necessitating prolonged ventilatory support, especially in the peri-operative phase. There has been an increase in the utilisation of non-invasive ventilatory support for these children. The objective of this study was to evaluate the utilisation, safety, and outcomes of RAM cannula as a tool for escalation and de-escalation of respiratory support in paediatric cardiac patients less than one year of age.

METHODS

A single-centre retrospective cohort study of patients supported with RAM cannula.

RESULTS

A total of 275 instances of RAM use were included in the study, 81.1% being post-operative. Patients were stratified into escalation and de-escalation cohorts based on the indication of non-invasive ventilation. The success rate of using RAM cannula was 69.5% overall, 66.1% in the escalation group, and 72.8% in the de-escalation group. At baseline, age at cardiac ICU admission >30 days, FiO2 ≤ 40%, PaCO2 ≤ 50 mmHg; and after 12 hours of non-invasive ventilation support respiratory rate ≤ 60/min, PaO2 ≥ 50 mmHg, PaCO2 ≤ 50 mmHg; and absence of worsening on follow-up chest X-ray predicted the success with a sensitivity of 95% in the logistic regression model. Successful support was associated with a significantly shorter unit stay.

CONCLUSIONS

RAM cannula can be safely used to provide non-invasive support to infants in the cardiac ICU for escalation and de-escalation of respiratory support. Factors associated with success can be used to make decisions about candidacy and appropriate timing of non-invasive ventilation use to maximise effectiveness.

Early factors related to mortality in children treated with bi-level noninvasive ventilation and CPAP

OBJECTIVE

To describe and analyze the characteristics and the early risk factors for mortality of noninvasive ventilation (NIV) in critically ill children.

STUDY DESIGN

A multicenter, prospective, observational 2-year study carried out with critically ill patients (1 month - 18 years of age) who needed NIV. Clinical data and NIV parameters during the first 12 h of admission were collected. A multilevel mixed-effects logistic regression was performed to identify mortality risk factors.

RESULTS

A total of 781 patients (44.2 ± 57.7 months) were studied (57.8% male). Of them, 53.7% had an underlying condition, and 47.1% needed NIV for lower airway respiratory pathologies. Bi-level NIV was the initial support in 78.2% of the patients. Continuous positive airway pressure (CPAP) was used more in younger patients (33.7%) than in older ones (9.7%; p < .001). About 16.7% had to be intubated and 6.2% died. The risk factors for mortality were immunodeficiency (odds ratio [OR] = 11.79; 95% confidence interval [CI] = 2.95-47.13); cerebral palsy (OR = 5.86; 95% CI = 1.94-17.65); presence of apneas on admission (OR = 5.57; 95% CI = 2.13-14.58); tachypnea 6 h after NIV onset (OR = 2.59; 95% CI = 1.30-6.94); and NIV failure (OR = 6.54; 95% CI = 2.79-15.34).

CONCLUSION

NIV is used with great variability in types of support. Younger children receive CPAP more frequently than older children. Immunodeficiency, cerebral palsy, apneas on admission, tachypnea 6 h after NIV onset, and NIV failure are the early factors associated with mortality.

Perioperative Noninvasive Ventilation After Adult or Pediatric Surgery: A Comprehensive Review

Postoperative pulmonary complications and acute respiratory failure are among the leading causes of adverse postoperative outcomes. Noninvasive ventilation may safely and effectively prevent acute respiratory failure in high-risk patients after cardiothoracic surgery and after abdominal surgery. Moreover, noninvasive ventilation can be used to treat postoperative hypoxemia, particularly after abdominal surgery. Noninvasive ventilation also can be helpful to prevent or manage intraoperative acute respiratory failure during non-general anesthesia, primarily in patients with poor respiratory function. Finally, noninvasive ventilation is superior to standard preoxygenation in delaying desaturation during intubation in morbidly obese and in critically ill hypoxemic patients. The few available studies in children suggest that noninvasive ventilation could be safe and valuable in treating hypoxemic or hypercapnic acute respiratory failure after cardiac surgery; on the other hand, it could be dangerous after tracheoesophageal correction.

Intensive Care Unit Management of the Adult with Congenital Heart Disease

PURPOSE

Adults with congenital heart disease (ACHD) are a rapidly growing population with ever-increasing complexity, and intensive care unit (ICU) management is often necessary. This review summarizes common cardiovascular and non-cardiovascular complications in ACHD and provides a framework for ICU care.

RECENT FINDINGS

Heart failure is the leading cause of hospitalization and mortality in ACHD. Varied anatomy and repairs, as well as differing physiological complications, limit generalized application of management algorithms. Recent studies suggest that earlier mechanical support in advanced cases is feasible and potentially helpful. Cardiac arrhythmias are poorly tolerated and often require immediate attention. Other complications requiring intensive care include infections such as endocarditis and COVID-19, pulmonary hypertension, renal failure, hepatic dysfunction, coagulopathy, and stroke. Successful ICU care in ACHD requires a multi-disciplinary approach with careful consideration of anatomy, physiology, and associated comorbidities. Few studies have formally examined ICU management in ACHD and further research is necessary.

Sugammadex Neuromuscular Blockade Reversal Associated With Lower Postoperative Arterial Carbon Dioxide Levels After Congenital Cardiac Surgery

OBJECTIVE

To compare postoperative arterial blood gas samples and requirement for respiratory support between patients who received sugammadex versus neostigmine reversal before extubation after congenital cardiac surgery.

DESIGN

Retrospective, cross-sectional study.

SETTING

Single-center, university-based, tertiary care hospital.

PARTICIPANTS

Patients with congenital heart disease undergoing surgery with cardiopulmonary bypass.

INTERVENTIONS

Chart review.

MEASUREMENTS AND MAIN RESULTS

The first postoperative arterial blood gas measurements were abstracted from electronic medical records, and reintubation or use of positive- pressure respiratory support within the first 24 postoperative hours was documented. Of the 237 charts reviewed, 111 (47%) patients received sugammadex reversal and 126 (53%) received neostigmine. Multivariate models showed that patients with 2-ventricle congenital heart disease who received sugammadex had lower postoperative arterial carbon dioxide partial pressure (PaCO₂) values (coefficient -3.1, 95% confidence interval [CI] -5.9 to -0.4; p = 0.026) and required less- noninvasive positive- pressure ventilation (odds ratio 0.3, 95% CI 0.1-0.8; p = 0.021). Single-ventricle congenital heart disease patients who received sugammadex had higher postoperative pH values (coefficient 0.04, 95% CI 0.01-0.06; p = 0.01) and lower PaCO₂ values (coefficient -5.2, 95% CI -9.6 to -0.8; p = 0.021).

CONCLUSION

Sugammadex reversal was associated with lower postoperative PaCO₂ values. In addition, sugammadex reversal was associated with less need for noninvasive positive- pressure ventilation in 2-ventricle patients. The magnitude of the effect appears modest, therefore the clinical significance remains unclear. Additional studies focused on investigating particular patient populations, such as infants, single-ventricle congenital heart disease, or patients with pulmonary hypertension, are needed to identify whether these patients appreciate a greater benefit from sugammadex reversal.

Consideration of the respiratory support strategy of severe acute respiratory failure caused by SARS-CoV-2 infection in children

The recent ongoing outbreak of severe pneumonia associated with a novel coronavirus (SARS-CoV-2), currently of unknown origin, creates a world emergency that has put global public health institutions on high alert. At present there is limited clinical information of the SARS-CoV-2 and there is no specific treatment recommended, although technical guidances and suggestions have been developed and will continue to be updated as additional information becomes available. Preventive treatment has an important role to control and avoid the spread of severe respiratory disease, but often is difficult to obtain and sometimes cannot be effective to reduce the risk of deterioration of the underlining lung pathology. In order to define an effective and safe treatment for SARS-CoV-2-associated disease, we provide considerations on the actual treatments, on how to avoid complications and the undesirable side effects related to them and to select and apply earlier the most appropriate treatment. Approaching to treat severe respiratory disease in infants and children, the risks related to the development of atelectasis starting invasive or non-invasive ventilation support and the risk of oxygen toxicity must be taken into serious consideration. For an appropriate and effective approach to treat severe pediatric respiratory diseases, two main different strategies can be proposed according to the stage and severity of the patient conditions: patient in the initial phase and with non-severe lung pathology and patient with severe initial respiratory impairment and/or with delay in arrival to observation. The final outcome is strictly connected with the ability to apply an appropriate treatment early and to reduce all the complications that can arise during the intensive care admission.

Use of Noninvasive Ventilation in Respiratory Failure After Extubation During Postoperative Care in Pediatrics

The purpose of this study was to determine the rate of failure of noninvasive ventilation (NIV) after cardiac surgery in pediatric patients with respiratory failure after extubation and to identify predictive success factors. This was a prospective cohort study of pediatric patients diagnosed with congenital heart disease who underwent heart surgery and used NIV. Data were collected from 170 patients with a median age of 2 months. No patient presented cardiorespiratory arrest nor any other complication during the use of NIV. The success rate for the use of NIV was 61.8%. Subjects were divided for analysis into successful and failed NIV groups. Statistical analysis used Chi-square, Mann-Whitney, and Student's t tests, which were performed after univariate and multivariate logistic regression for p < 0.05. In the multivariate analysis, only the minimal pressure gradient (OR 1.45 with p = 0.007), maximum oxygen saturation (OR 0.88 with p = 0.011), and maximum fraction of inspired oxygen (FiO₂) (OR 1.16 with p < 0.001) influenced NIV failure. The following variables did not present a statistical difference: extracorporeal circulation time (p = 0.669), pulmonary hypertension (p = 0.254), genetic syndrome (p = 0.342), RACHS-1 score (p = 0.097), age (p = 0.098), invasive mechanical ventilation duration (p = 0.186), and NIV duration (p = 0.804). In conclusion, NIV can be successfully used in children who, after cardiac surgery, develop respiratory failure in the 48 h following extubation. Although the use of higher pressure gradients and higher FiO₂ are associated with a greater failure rate for NIV use, it was found to be generally safe.

Contemporary ventilatory strategies for surgical patients

Respiratory failure affects a significant percentage of critically ill children, necessitating both invasive and non-invasive respiratory support. As the outcomes of these patients have improved, children with higher acuity and more complex respiratory pathophysiology require mechanical ventilation. Despite growing understanding of lung-protective strategies and ventilation induced lung injury, certain patients still require harmful ventilatory settings with conventional mechanical ventilation (CMV). High frequency ventilation, neurally adjusted ventilatory assist, and airway pressure release ventilation offer feasible alternatives to CMV. In addition to minimizing the risk of ventilatory induced lung injury when used appropriately, they provide a unique environment to facilitate operations on certain neonates and older children. Finally, non-invasive ventilation is now commonly employed in children with surgical conditions.

Cardiopulmonary Resuscitation in Infants and Children With Cardiac Disease: A Scientific Statement From the American Heart Association

Cardiac arrest occurs at a higher rate in children with heart disease than in healthy children. Pediatric basic life support and advanced life support guidelines focus on delivering high-quality resuscitation in children with normal hearts. The complexity and variability in pediatric heart disease pose unique challenges during resuscitation. A writing group appointed by the American Heart Association reviewed the literature addressing resuscitation in children with heart disease. MEDLINE and Google Scholar databases were searched from 1966 to 2015, cross-referencing pediatric heart disease with pertinent resuscitation search terms. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. The recommendations in this statement concur with the critical components of the 2015 American Heart Association pediatric basic life support and pediatric advanced life support guidelines and are meant to serve as a resuscitation supplement. This statement is meant for caregivers of children with heart disease in the prehospital and in-hospital settings. Understanding the anatomy and physiology of the high-risk pediatric cardiac population will promote early recognition and treatment of decompensation to prevent cardiac arrest, increase survival from cardiac arrest by providing high-quality resuscitations, and improve outcomes with postresuscitation care.

CPAP by helmet for treatment of acute respiratory failure after pediatric liver transplantation

ARF after pediatric liver transplantation accounts for high rate of morbidity and mortality associated with this procedure. The role of CPAP in postoperative period is still unknown. The aim of the study was to describe current practice and risk factors associated with the application of helmet CPAP. In this retrospective observational cohort study, 119 recipients were divided into two groups based on indication to CPAP after extubation. Perioperative variables were studied, and determinants of CPAP application were analyzed in a multivariate logistic model. Sixty patients (60/114) developed ARF and were included in the CPAP group. No differences were found between the two groups for primary disease, graft type, and blood product transfused. At multivariate analysis, weight <11 kg (OR = 2.9; 95% CI = 1.1-7.3; P = .026), PaO₂ /FiO₂ <380 before extubation (OR = 5.4; 95% CI = 2.1-13.6; P < .001), need of vasopressors (OR = 2.6; 95% CI = 1.1-6.4; P = .038), and positive fluid balance >148 mL/kg (OR = 4.0; 95% CI = 1.6-10.1; P = .004) were the main determinants of CPAP application. In the CPAP group, five patients (8.4%) needed reintubation. Pediatric liver recipients with lower weight, higher need of inotropes/vasopressors, higher positive fluid balance after surgery, and lower PaO₂ /FiO₂ before extubation were at higher odds of developing ARF needing CPAP application.

Epidemiology of Noninvasive Ventilation in Pediatric Cardiac ICUs

OBJECTIVE

To describe the epidemiology of noninvasive ventilation therapy for patients admitted to pediatric cardiac ICUs and to assess practice variation across hospitals.

DESIGN

Retrospective cohort study using prospectively collected clinical registry data.

SETTING

Pediatric Cardiac Critical Care Consortium clinical registry.

PATIENTS

Patients admitted to cardiac ICUs at PC4 hospitals.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We analyzed all cardiac ICU encounters that included any respiratory support from October 2013 to December 2015. Noninvasive ventilation therapy included high flow nasal cannula and positive airway pressure support. We compared patient and, when relevant, perioperative characteristics of those receiving noninvasive ventilation to all others. Subgroup analysis was performed on neonates and infants undergoing major cardiovascular surgery. To examine duration of respiratory support, we created a casemix-adjustment model and calculated adjusted mean durations of total respiratory support (mechanical ventilation + noninvasive ventilation), mechanical ventilation, and noninvasive ventilation. We compared adjusted duration of support across hospitals. The cohort included 8,940 encounters from 15 hospitals: 3,950 (44%) received noninvasive ventilation and 72% were neonates and infants. Medical encounters were more likely to include noninvasive ventilation than surgical. In surgical neonates and infants, 2,032 (55%) received postoperative noninvasive ventilation. Neonates, extracardiac anomalies, single ventricle, procedure complexity, preoperative respiratory support, mechanical ventilation duration, and postoperative disease severity were associated with noninvasive ventilation therapy (p < 0.001 for all). Across hospitals, noninvasive ventilation use ranged from 32% to 65%, and adjusted mean noninvasive ventilation duration ranged from 1 to 4 days (3-d observed mean). Duration of total adjusted respiratory support was more strongly correlated with duration of mechanical ventilation compared with noninvasive ventilation (Pearson r = 0.93 vs 0.71, respectively).

CONCLUSIONS

Noninvasive ventilation use is common in cardiac ICUs, especially in patients admitted for medical conditions, infants, and those undergoing high complexity surgery. We observed wide variation in noninvasive ventilation use across hospitals, though the primary driver of total respiratory support time seems to be duration of mechanical ventilation.

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.

Non-invasive mechanical ventilation after heart surgery in children

Background

The purpose of the study was to analyze the characteristics and evolution of non-invasive mechanical ventilation (NIV) in the postoperative period of heart surgery in children.

Methods

Retrospective observational study including all children requiring NIV after heart surgery in a single center pediatric intensive care unit (PICU) between 2001 and 2012. Demographic characteristics, ventilation parameters and outcomes were registered, comparing the first 6 years of the study with the last 6 years.

Results

935 children required invasive or non-invasive mechanical ventilation, of which 200 (21.4) received NIV. The median duration of NIV was 3 days. Mortality rate was 3.9%. The use of NIV increased from 13.2% in the first period to 29.2% in the second period (p <0.001). Continuous positive airway pressure (CPAP) was the most common modality of NIV (65.5%). The use of bilevel positive airway pressure mode (BIPAP) increased from 15% in the first period to 42.9% in the second period (p < 0.001). The nasopharyngeal tube was the most common interface (66%), but the use of nasal cannula increased from 3.3 to 41.4% in the second period (p < 0.001). NIV failed in 15% of patients. The mortality rate did not change, the duration of NIV decreased and the PICU length of stay increased throughout the study.

Conclusions

NIV is increasingly being used in the postoperative period of heart surgery in our center with an 85% success rate and is associated with a lesser need for invasive mechanical ventilation. CPAP was the most common modality and the “nasopharyngeal tube” was the most common interface in our study although, in the latter years, the use of BIPAP and nasal cannula has increased significantly.

Predictors of Early Extubation After Pediatric Cardiac Surgery: A Single-Center Prospective Observational Study

This prospective, observational, single-center study aimed to determine the perioperative predictors of early extubation (<24 h after cardiac surgery) in a cohort of children undergoing cardiac surgery. Children aged between 1 month and 18 years who were consecutively admitted to pediatric intensive care unit after cardiac surgery for congenital heart disease between January 2012 and June 2014. Ninety-nine patients were qualified for inclusion during the study period. The median duration of mechanical ventilation was 20 h (range 1-480), and 64 patients were extubated within 24 h. Four of them failed the initial attempt at extubation, and the success rate of early extubation was 60.6 %. Older patient age (p = .009), greater body weight (p = .009), absence of preoperative pulmonary hypertension (p = .044), lower RACHS-1 category (OR, 3.8; 95 % CI 1.35-10.7; p < .05), shorter cardiopulmonary bypass (p = .008) and cross-clamp (p = .022) times, lower PRISM III-24 (p < .05) and PELOD (p < .05) scores, lower inotropic score (p < .05) and vasoactive-inotropic score (p < .05), and lower number of organ failures (OR, 2.26; 95 % CI 1.30-3.92; p < .05) were associated with early extubation. Our study establishes that early extubation can be accomplished within the first 24 h after surgery in low- to medium-risk pediatric cardiac surgery patients, especially in older ones undergoing low-complexity procedures. A large prospective multiple institution trial is necessary to identify the predictors and benefits of early extubation and to facilitate defined guidelines for early extubation.

Effectiveness of prophylactic non-invasive ventilation on respiratory function in the postoperative phase of pediatric cardiac surgery: a randomized controlled trial

Objective

To evaluate the effectiveness of prophylactic, non-invasive ventilation (NIV) on respiratory function in seven- to 16-year-old children in the post-operative phase of cardiac surgery.

Method

A randomized, controlled trial with 50 children who had undergone cardiac surgery with median sternotomy. After extubation, patients were randomly assigned to one of two groups: control group (n=26), which received instructions regarding posture, early ambulation, and cough stimulation, and CPAP group (continuous positive airway pressure; n=24), which received the same instructions as the control group and CPAP=10 cmH₂0 twice daily for 30 minutes from the 1^st to the 5^th post-operative day (POD). As a primary outcome, lung function was evaluated before and on the 1^st, 3^rd, and 5^th PODs with measures of respiratory rate (RR), tidal volume (TV), slow vital capacity (SVC), inspiratory capacity (IC), minute volume (MV), peak expiratory flow (PEF), and maximal inspiratory pressure (MIP). As secondary outcomes, the time of hospitalization and intensive care were recorded. A mixed, linear regression model and z-test were used to analyze respiratory function, considering p<0.05.

Results

All variables, except RR and MV, showed a significant drop on the 1^st POD, with gradual recovery; however, only MIP had returned to pre-operative values on the 5^th POD in both groups. The RR showed a significant increase on the 1^st POD, with a gradual reduction but without returning to baseline. In the intergroup analysis, significant improvement (p=0.04) was observed only in PEF in the CPAP group on the 1^st DPO. The length of hospitalization and intensive care showed no significant differences.

Conclusion

NIV was safe and well accepted in this group of patients, and the protocol used was effective in improving PEF on the 1^st DPO in the CPAP group.

Does continuous positive airway pressure for extubation in congenital tracheoesophageal fistula increase the risk of anastomotic leak? A retrospective cohort study

AIM

Immediate post-operative care of tracheoesophageal fistula (TEF) and oesophageal atresia (EA) requires mechanical ventilation. Early extubation is preferred, but subsequent respiratory distress may warrant re-intubation. Continuous positive airway pressure (CPAP) is a well-established modality to prevent extubation failures in preterm infants. However, it is not favoured in TEF/EA, because of the theoretical risk of oesophageal anastomotic leak (AL). The aim of this study was to find out if post-extubation CPAP is associated with increased risk of AL.

METHODS

Retrospective cohort study (2007-2014).

RESULTS

Fifty-one infants underwent primary repair in the newborn period. Median age at surgery was 24 h (interquartile range: 12, 24). In the post-extubation period, 10 received CPAP, whereas 41 did not. The median post-operative day at the commencement of CPAP was 2.5 days (interquartile range: 1, 6 days). Zero out of 10 in the CPAP group and 4/41 in the 'no CPAP' group developed AL on routine post-operative contrast studies (P = 0.57). Zero out of 10 in the CPAP group and 1/41 in the 'no CPAP group' developed recurrence of TEF necessitating re-surgery (P = 1.00). The neonate with recurrent fistula also had coarctation of aorta and needed protracted hospitalisation of 6 months, mainly because of the recurrence of TEF.

CONCLUSION

The use of CPAP in the immediate post-extubation period after corrective surgery for TEF/EA appears to be safe and may not be associated with increased risk of AL or recurrence of the fistula. Information from other centres, surveys and large databases is needed to define the benefits and risks of use of CPAP in these infants.

Experts' recommendations for the management of cardiogenic shock in children

Cardiogenic shock which corresponds to an acute state of circulatory failure due to impairment of myocardial contractility is a very rare disease in children, even more than in adults. To date, no international recommendations regarding its management in critically ill children are available. An experts’ recommendations in adult population have recently been made (Levy et al. Ann Intensive Care 5(1):52, 2015; Levy et al. Ann Intensive Care 5(1):26, 2015). We present herein recommendations for the management of cardiogenic shock in children, developed with the grading of recommendations’ assessment, development, and evaluation system by an expert group of the Groupe Francophone de Réanimation et Urgences Pédiatriques (French Group for Pediatric Intensive Care and Emergencies). The recommendations cover four major fields of application such as: recognition of early signs of shock and the patient pathway, management principles and therapeutic goals, monitoring hemodynamic and biological variables, and circulatory support (indications, techniques, organization, and transfer criteria). Major principle care for children with cardiogenic shock is primarily based on clinical and echocardiographic assessment. There are few drugs reported as effective in childhood in the medical literature. The use of circulatory support should be facilitated in terms of organization and reflected in the centers that support these children. Children with cardiogenic shock are vulnerable and should be followed regularly by intensivist cardiologists and pediatricians. The experts emphasize the multidisciplinary nature of management of children with cardiogenic shock and the importance of effective communication between emergency medical assistance teams (SAMU), mobile pediatric emergency units (SMUR), pediatric emergency departments, pediatric cardiology and cardiac surgery departments, and pediatric intensive care units.

Efficacy of noninvasive mechanical ventilation in prevention of intubation and reintubation in the pediatric intensive care unit

PURPOSE

To determine the efficiency of noninvasive mechanical ventilation (NIV) both in protection from intubation and in preventing reintubation of postextubation in patients in the pediatric intensive care unit (PICU).

METHODS

A prospective observational study was conducted in a multidisciplinary 10-bed tertiary PICU of a university hospital. All patients were admitted to our unit from June 2012 to May 2014 and deemed to be candidates to receive continuous positive airway pressure or bilevel positive airway pressure.

MEASUREMENTS AND RESULTS

We performed 160 NIV episodes in 137 patients. Their median age was 9 months (range, 1-240 months), and their median weight was 7.5 kg (range, 2.5-65 kg). Fifty-seven percent of patients were male. Noninvasive mechanical ventilation was successful in 70% (112 episodes) of patients. There was an underlying illness in 83.8% (134 episodes) of the patients. Bilevel positive airway pressure support was given to 57.5% (92 episodes) of the patients, whereas the remaining 42.5% (68 episodes) received continuous positive airway pressure support. Among the causes of respiratory failure in our patients, the most frequent were postextubation, pneumonia, bronchiolitis, atelectasia, and cardiogenic pulmonary edema. Sedation was applied in 43.1% of the episodes. Complications were detected in 29 episodes (18.1 %). The NIV failure group showed higher Pediatric Risk of Mortality III-24 score, shorter NIV duration, more frequent underlying disease, lower number fed, longer length of PICU stay, and hospital stay, and mortality was higher.

CONCLUSIONS

Noninvasive mechanical ventilation effectively and reliably reduced endotracheal intubation in the treatment of respiratory failure due to different clinical situations. Our results suggest that NIV can play an important role in PICUs in helping to avoid intubation and prevent reintubation. Although there were serious underlying diseases in most of our patients, such as immunosuppression, 70% avoided intubation with use of NIV.

Risk Factors for Extubation Failure Following Neonatal Cardiac Surgery

OBJECTIVE

Extubation failure after neonatal cardiac surgery has been associated with considerable postoperative morbidity, although data identifying risk factors for its occurrence are sparse. We aimed to determine risk factors for extubation failure in our neonatal cardiac surgical population.

DESIGN

Retrospective chart review.

SETTING

Urban tertiary care free-standing children's hospital.

PATIENTS

Neonates (0-30 d) who underwent cardiac surgery at our institution between January 2009 and December 2012 was performed.

INTERVENTIONS

Extubation failure was defined as reintubation within 72 hours after extubation from mechanical ventilation. Multivariate logistic regression analysis was performed to determine independent risk factors for extubation failure.

MEASUREMENTS AND MAIN RESULTS

We included 120 neonates, of whom 21 (17.5%) experienced extubation failure. On univariate analysis, patients who failed extubation were more likely to have genetic abnormalities (24% vs 6%; p = 0.023), hypoplastic left heart (43% vs 17%; p = 0.009), delayed sternal closure (38% vs 12%; p = 0.004), postoperative infection prior to extubation (38% vs 11%; p = 0.002), and longer duration of mechanical ventilation (median, 142 vs 58 hr; p = 0.009]. On multivariate analysis, genetic abnormalities, hypoplastic left heart, and postoperative infection remained independently associated with extubation failure. Furthermore, patients with infection who failed extubation tended to receive fewer days of antibiotics prior to their first extubation attempt when compared with patients with infection who did not fail extubation (4.9 ± 2.6 vs 7.3 ± 3; p = 0.073).

CONCLUSIONS

Neonates with underlying genetic abnormalities, hypoplastic left heart, or postoperative infection were at increased risk for extubation failure. A more conservative approach in these patients, including longer pre-extubation duration of antibiotic therapy for postoperative infections, may be warranted.

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.

Critical care management of the adult patient with congenital heart disease: focus on postoperative management and outcomes

OPINION STATEMENT

Advances in surgical techniques and in the medical management of children with congenital heart disease has increased survival into adulthood, resulting in a population of adults with congenital heart disease now surpassing the pediatric population in numbers. Furthermore, many of the patients will require repeat surgical, catheter-based, procedures and/or obstetrical care in their adult lives, and understanding the specific cardiopulmonary physiology and the involvement of other organ systems is critical to successful intervention. A team approach, with consultants from medical specialties in the setting of an established adult congenital heart center, is the optimal setting for superior outcomes. In this review, we discuss critical care management of the adult congenital heart disease patient in the perioperative period.
