Evaluating the introduction of extracorporeal life support technology to a tertiary-care pediatric institution: Smoothing the learning curve through interprofessional simulation training.

BACKGROUND: Extracorporeal life support (ECLS) is a life-saving technology for the critically ill child. Our objective was to evaluate the outcomes of an educational curriculum designed to introduce an ECLS program to a noncardiac pediatric surgical center. METHODS: An interdisciplinary curriculum was developed consisting of didactic courses, animal labs, simulations, and debrief sessions. We reviewed all patients requiring ECLS between October 2011 and December 2013. All health care practitioners involved in the ECLS training curriculum were surveyed to evaluate their perception of the educational program. Primary outcomes include successful cannulation and 30-day survival. RESULTS: The knowledge and confidence improved with statistical significance (p<0.0001-0.0003) for all of the components of the training curriculum. The highest score was given to the simulations. Twenty-one patients underwent cannulation. All patients were successfully cannulated to bypass, including six (28.6%) ECPR. Median time from activation to cutting was 52min (IQR 40-72), and from cutting to bypass 40min (IQR 30-45). Sixteen patients (76.2%) were decannulated to a sustainable cardiac rhythm and survived 30-days. CONCLUSION: An ECLS curriculum incorporating simulation and dedicated practice seems to have eliminated the potential learning curve associated with the introduction of a complex technology to a novice environment.

Air transported pediatric rescue extracorporeal membrane oxygenation: a single institutional review.

BACKGROUND: Pediatric extracorporeal membrane oxygenation (ECMO) programs are sophisticated endeavors usually found only in high-volume cardiac surgical programs. Worldwide, many cardiology programs do not have on-site pediatric cardiac surgery expertise. Our single-center experience shows that an organized multidisciplinary rescue-ECMO program, in collaboration with an accepting facility, can achieve survival rates comparable to modern era on-site ECMO. METHODS: A retrospective review was conducted of all patients initiated on rescue-ECMO from 2004 to 2009 in a single academic pediatric hospital without a pediatric cardiac surgery program. All aspects of ECMO were formalized using Failure Mode Effects Analysis. RESULTS: Eight patients were initially cannulated for ECMO at our institution. Six were subsequently transported by air to the receiving facility 1,305 km away. Extracorporeal membrane oxygenation was initiated in 0.2% of our Pediatric Intensive Care Unit admissions and in 0.52% of all our pediatric cardiac patients. Mean age was 4.0 years (7 weeks to 15 years). Indications for ECMO initiations were cardiogenic shock (n = 5) and acute respiratory distress syndrome (n = 3). Six had veno-arterial- and two had veno-veno ECMO. Two patients were not transported (one death and one weaned locally). Six patients were successfully transported within 2 to 24 hours, with a survival to hospital discharge rate of 67% (four of six). Median total time on ECMO was 5.5 days. Complication rate was 50% (4/8). CONCLUSIONS: Our rescue-ECMO survival results were comparable to that of current published results from established pediatric ECMO programs. Air transport of ECMO patients can be performed safely using an organized multidisciplinary team approach.

Critical illness in children with influenza A/pH1N1 2009 infection in Canada.

OBJECTIVE: To describe characteristics, treatment, and outcomes of critically ill children with influenza A/pandemic influenza A virus (pH1N1) infection in Canada. DESIGN: An observational study of critically ill children with influenza A/pH1N1 infection in pediatric intensive care units (PICUs). SETTING: Nine Canadian PICUs. PATIENTS: A total of 57 patients admitted to PICUs between April 16, 2009 and August 15, 2009. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Characteristics of critically ill children with influenza A/pH1N1 infection were recorded. Confirmed intensive care unit cases were compared with a national surveillance database containing all hospitalized pediatric patients with influenza A/pH1N1 infection. Risk factors were assessed with a Cox proportional hazard model. The PICU cohort and national surveillance data were compared, using chi-square tests. Fifty-seven children were admitted to the PICU for community-acquired influenza A/pH1N1 infection. One or more chronic comorbid illnesses were observed in 70.2% of patients, and 24.6% of patients were aboriginal. Mechanical ventilation was used in 68% of children, 20 children (35.1%) had acute lung injury on the first day of admission, and the median duration of ventilation was 6 days (range, 0-67 days). The PICU mortality rate was 7% (4 of 57 patients). When compared with nonintensive care unit hospitalized children, PICU children were more likely to have a chronic medical condition (relative risk, 1.73); aboriginal ethnicity was not a risk factor of intensive care unit admission. CONCLUSIONS: During the first outbreak of influenza A/pH1N1 infection, when the population was naïve to this novel virus, severe illness was common among children with underlying chronic conditions and aboriginal children. Influenza A/pH1N1-related critical illness in children was associated with severe hypoxemic respiratory failure and prolonged mechanical ventilation. However, this higher rate and severity of respiratory illness did not result in an increased mortality when compared with seasonal influenza.

Extracorporeal lung support for patients who had severe respiratory failure secondary to influenza A (H1N1) 2009 infection in Canada.

BACKGROUND: From March to July 2009, influenza A (H1N1) 2009 (H1N1-2009) virus emerged as a major cause of respiratory failure that required mechanical ventilation. A small proportion of patients who had this condition developed severe respiratory failure that was unresponsive to conventional therapeutic interventions. In this report, we describe characteristics, treatment, and outcomes of critically ill patients in Canada who had H1N1-2009 infection and were treated with extracorporeal lung support (ECLS). METHODS: We report the findings of a case series of six patients supported with ECLS who were included in a cohort study of critically ill patients with confirmed H1N1-2009 infection. The patients were treated in Canadian adult and pediatric intensive care units (ICUs) from April 16, 2009 to August 12, 2009. We describe the nested sample treated with ECLS and compare it with the larger sample. RESULTS: During the study period, 168 patients in Canada were admitted to ICUs for severe respiratory failure due to confirmed H1N1-2009 infection. Due to profound hypoxemia unresponsive to conventional therapeutic interventions, six (3.6%) of these patients were treated with ECLS in four ICUs. Four patients were treated with veno-venous pump-driven extracorporeal membrane oxygenation (vv-ECMO), and two patients were treated with pumpless lung assist (NovaLung iLA). The mean duration of support was 15 days. Four of the six patients survived (66.6%), one of the surviving patients was supported with iLA and the other three surviving patients were supported with ECMO. The two deaths were due to multiorgan failure, which occurred while the patients were on ECLS. INTERPRETATION: Extracorporeal lung support may be an effective treatment for patients who have H1N1-2009 infection and refractory hypoxemia. Survival of these patients treated with ECLS is similar to that reported for patients who have acute respiratory distress syndrome of other etiologies and are treated with ECMO.
