Part 6: Pediatric basic life support and pediatric advanced life support. 2015 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science with Treatment Recommendations

The Pediatric Task Force reviewed all questions submitted by the International Liaison Committee on Resuscitation (ILCOR) member councils in 2010, reviewed all council training materials and resuscitation guidelines and algorithms, and conferred on recent areas of interest and controversy. We identified a few areas where there were key differences in council-specific guidelines based on historical recommendations, such as the A-B-C (Airway, Breathing, Circulation) versus C-A-B (Circulation, Airway, Breathing) sequence of provision of cardiopulmonary resuscitation (CPR), initial back blows versus abdominal thrusts for foreign-body airway obstruction, an upper limit for recommended chest compression rate, and initial defibrillation dose for shockable rhythms (2 versus 4 J/kg). We produced a working list of prioritized questions and topics, which was adjusted with the advent of new research evidence. This led to a prioritized palate of 21 PICO (population, intervention, comparator, outcome) questions for ILCOR task force focus. The 2015 process was supported by information specialists who performed in-depth systematic searches, liaising with pediatric content experts so that the most appropriate terms and outcomes and the most relevant publications were identified. Relevant adult literature was considered (extrapolated) in those PICO questions that overlapped with other task forces, or when there were insufficient pediatric data. In rare circumstances (in the absence of sufficient human data), appropriate animal studies were incorporated into reviews of the literature. However, these data were considered only when higher levels of evidence were not available and the topic was deemed critical. When formulating the PICO questions, the task force felt it important to evaluate patient outcomes that extend beyond return of spontaneous circulation (ROSC) or discharge from the pediatric intensive care unit (PICU). In recognition that the measures must have meaning, not only to clinicians but also to parents and caregivers, longer-term outcomes at 30 …

Citrate anticoagulation in a piglet model of pediatric continuous renal replacement therapy.

Objective To develop pediatric guidelines for the use of citrate as a regional anticoagulant for continuous renal replacement therapy (CRRT) using a neonatal piglet model. Design Prospective observational study. Setting Animal laboratory in the research center of a tertiary-level children’s hospital. Subjects Ten neonatal piglets. Interventions and Measurements Using a venovenous CRRT circuit and filter, we randomly altered the filter blood flow rate, replacement flow rate, and citrate flow rate over conventional pediatric ranges. Measured end points were prefilter serum ionized calcium and citrate levels. Main Results A prefilter serum citrate concentration of 6 mmol/L is required to maintain the prefilter ionized calcium ≤0.4 mmol/L. Using multiple regression analysis on collected data, we derived a formula to predict prefilter serum citrate for combinations of replacement flow rate, blood flow rate, and citrate flow rate. Conclusions The available literature and our past experience indicate that a prefilter ionized calcium ≤0.4 mmol/L is required to anticoagulate a CRRT circuit; a prefilter serum citrate concentration of 6 mmol/L is required to achieve this. Our multiple regression analysis can be expressed graphically to allow easy calculation of the required citrate flow rate, given the knowledge of the replacement flow rate and blood flow rate. Our results provide the first guidelines for the use of citrate as a regional anticoagulant in a pediatric-size model of CRRT.

Relationship Between Adverse Tracheal Intubation Associated Events and PICU Outcomes

Objective: Tracheal intubation in PICUs is a common procedure often associated with adverse events. The aim of this study is to evaluate the association between immediate events such as tracheal intubation associated events or desaturation and ICU outcomes: length of stay, duration of mechanical ventilation, and mortality. Study Design: Prospective cohort study with 35 PICUs using a multicenter tracheal intubation quality improvement database (National Emergency Airway Registry for Children: NEAR4KIDS) from January 2013 to June 2015. Desaturation defined as Spo2 less than 80%. Setting: PICUs participating in NEAR4KIDS. Patients: All patients less than18 years of age undergoing primary tracheal intubations with ICU outcome data were analyzed. Measurements and Main Results: Five thousand five hundred four tracheal intubation encounters with median 108 (interquartile range, 58–229) tracheal intubations per site. At least one tracheal intubation associated event was reported in 892 (16%), with 364 (6.6%) severe tracheal intubation associated events. Infants had a higher frequency of tracheal intubation associated event or desaturation than older patients (48% infants vs 34% for 1–7 yr and 18% for 8–17 yr). In univariate analysis, the occurrence of tracheal intubation associated event or desaturation was associated with a longer mechanical ventilation (5 vs 3 d; p < 0.001) and longer PICU stay (14 vs 11 d; p < 0.001) but not with PICU mortality. The occurrence of severe tracheal intubation associated events was associated with longer mechanical ventilation (5 vs 4 d; p < 0.003), longer PICU stay (15 vs 12 d; p < 0.035), and PICU mortality (19.9% vs 9.6%; p < 0.0001). In multivariable analyses, the occurrence of tracheal intubation associated event or desaturation was significantly associated with longer mechanical ventilation (+12%; 95% CI, 4–21%; p = 0.004), and severe tracheal intubation associated events were independently associated with increased PICU mortality (OR = 1.80; 95% CI, 1.24–2.60; p = 0.002), after adjusted for patient confounders. Conclusions: Adverse tracheal intubation associated events and desaturations are common and associated with longer mechanical ventilation in critically ill children. Severe tracheal intubation associated events are associated with higher ICU mortality. Potential interventions to decrease tracheal intubation associated events and oxygen desaturation, such as tracheal intubation checklist, use of apneic oxygenation, and video laryngoscopy, may need to be considered to improve ICU outcomes.

Basic and advanced paediatric cardiopulmonary resuscitation – Guidelines of the Australian and New Zealand Resuscitation Councils 2010

Guidelines for basic and advanced paediatric cardiopulmonary resuscitation (CPR) have been revised by Australian and New Zealand Resuscitation Councils. Changes encourage CPR out‐of‐hospital and aim to improve the quality of CPR in‐hospital. Features of basic CPR include: omission of abdominal thrusts for foreign body airway obstruction; commencement with chest compression followed by ventilation in a ratio of 30:2 or compression‐only CPR if the rescuer is unwilling/unable to give expired‐air breathing when the victim is ‘unresponsive and not breathing normally’. Use of automated external defibrillators is encouraged. Features of advanced CPR include: prevention of cardiac arrest by rapid response systems; restriction of pulse palpation to 10 s to diagnosis cardiac arrest; affirmation of 15:2 compression–ventilation ratio for children and for infants other than newly born; initial bag‐mask ventilation before tracheal intubation; a single direct current shock of 4 J/kg for ventricular fibrillation (VF) and pulseless ventricular tachycardia followed by immediate resumption of CPR for 2 min without analysis of cardiac rhythm and avoidance of unnecessary interruption of continuous external cardiac compressions. Monitoring of exhaled carbon dioxide is recommended to detect non‐tracheal intubation, assess quality of CPR, and to help match ventilation to reduced cardiac output. The intraosseous route is recommended if immediate intravenous access is impossible. Amiodarone is strongly favoured over lignocaine for refractory VF and adrenaline over atropine for severe bradycardia, asystole and pulseless electrical activity. Family presence at resuscitation is encouraged. Therapeutic hypothermia is acceptable after resuscitation to improve neurological outcome. Extracorporeal circulatory support for in‐hospital cardiac arrest may be used in equipped centres.

Increased Occurrence of Tracheal Intubation-Associated Events During Nights and Weekends in the PICU.

Objectives:Adverse tracheal intubation–associated events are common in PICUs. Prior studies suggest provider and practice factors are important contributors to tracheal intubation–associated events. Little is known about how the incidence of tracheal intubation–associated events is affected by the time of day, day of the week, or presence of in-hospital attending-level intensivists. We hypothesize that tracheal intubations occurring during nights and weekends are associated with a higher frequency of tracheal intubation–associated events. Design:Retrospective observational cohort study. Setting:Twenty international PICUs. Subjects:Critically ill children requiring tracheal intubation. Interventions:None. Measurements and Main Results:We analyzed 5,096 tracheal intubation courses from July 2010 to March 2014 from the prospective multicenter National Emergency Airway Registry for Children. Frequency of a priori–defined tracheal intubation–associated events was the primary outcome. Occurrence of any tracheal intubation–associated events and severe tracheal intubation–associated events were more common during nights (19:00 to 06:59) and weekends compared with weekdays (19% vs 16%, p = 0.01; 7% vs 6%, p = 0.05, respectively). This difference was significant in emergent intubations after adjusting for site-level clustering and patient factors: for any tracheal intubation–associated events: adjusted odds ratio, 1.20; 95% CI, 1.02–1.41; p = 0.03; but not significant in nonemergent intubations: adjusted odds ratio, 0.94; 95% CI, 0.63–1.40; p = 0.75. For emergent intubations, PICUs with home-call attending coverage had a significantly higher frequency of tracheal intubation–associated events during nights and weekends (adjusted odds ratio, 1.29; 95% CI, 1.01–1.66; p = 0.04), and this difference was attenuated in PICUs with in-hospital attending coverage (adjusted odds ratio, 1.12; 95% CI, 0.91–1.39; p = 0.28). Conclusions:Higher occurrence of tracheal intubation–associated events was observed during nights and weekends. This difference was primarily attributed to emergent intubations. In- hospital attending physician coverage attenuated this discrepancy between weekdays versus nights and weekends but was not fully protective for tracheal intubation–associated events.

Clinical Impact of External Laryngeal Manipulation During Laryngoscopy on Tracheal Intubation Success in Critically Ill Children

Objectives: External laryngeal manipulation is a commonly used maneuver to improve visualization of the glottis during tracheal intubation in children. However, the effectiveness to improve tracheal intubation attempt success rate in the nonanesthesia setting is not clear. The study objective was to evaluate the association between external laryngeal manipulation use and initial tracheal intubation attempt success in PICUs. Design: A retrospective observational study using a multicenter emergency airway quality improvement registry. Setting: Thirty-five PICUs within general and children’s hospitals (29 in the United States, three in Canada, one in Japan, one in Singapore, and one in New Zealand). Patients: Critically ill children (< 18 years) undergoing initial tracheal intubation with direct laryngoscopy in PICUs between July 1, 2010, and December 31, 2015. Measurements and Main Results: Propensity score–matched analysis was performed to evaluate the association between external laryngeal manipulation and initial attempt success while adjusting for underlying differences in patient and clinical care factors: age, obesity, tracheal intubation indications, difficult airway features, provider training level, and neuromuscular blockade use. External laryngeal manipulation was defined as any external force to the neck during laryngoscopy. Of the 7,825 tracheal intubations, the initial tracheal intubation attempt was successful in 1,935/3,274 intubations (59%) with external laryngeal manipulation and 3,086/4,551 (68%) without external laryngeal manipulation (unadjusted odds ratio, 0.69; 95% CI, 0.62–0.75; p < 0.001). In propensity score–matched analysis, external laryngeal manipulation remained associated with lower initial tracheal intubation attempt success (adjusted odds ratio, 0.93; 95% CI, 0.90–0.95; p < 0.001). Conclusions: External laryngeal manipulation during direct laryngoscopy was associated with lower initial tracheal intubation attempt success in critically ill children, even after adjusting for underlying differences in patient factors and provider levels. The indiscriminate use of external laryngeal manipulation cannot be recommended.

Frequency of Desaturation and Association with Hemodynamic Adverse Events during Tracheal Intubations in PICUs

Objectives: Oxygen desaturation during tracheal intubation is known to be associated with adverse ICU outcomes in critically ill children. We aimed to determine the occurrence and severity of desaturation during tracheal intubations and the association with adverse hemodynamic tracheal intubation–associated events. Design: Retrospective cohort study as a part of the National Emergency Airway Registry for Children Network’s quality improvement project from January 2012 to December 2014. Setting: International PICUs. Patients: Critically ill children younger than 18 years undergoing primary tracheal intubations in the ICUs. Interventions: tracheal intubation processes of care and outcomes were prospectively collected using standardized operational definitions. We defined moderate desaturation as oxygen saturation less than 80% and severe desaturation as oxygen saturation less than 70% during tracheal intubation procedures in children with initial oxygen saturation greater than 90% after preoxygenation. Adverse hemodynamic tracheal intubation–associated event was defined as cardiac arrests, hypo or hypertension requiring intervention, and dysrhythmia. Measurements and Main Results: A total of 5,498 primary tracheal intubations from 31 ICUs were reported. Moderate desaturation was observed in 19.3% associated with adverse hemodynamic tracheal intubation–associated events (9.8% among children with moderate desaturation vs 4.4% without desaturation; p < 0.001). Severe desaturation was observed in 12.9% of tracheal intubations, also significantly associated with hemodynamic tracheal intubation–associated events. After adjusting for patient, provider, and practice factors, the occurrence of moderate desaturation was independently associated with hemodynamic tracheal intubation–associated events: adjusted odds ratio 1.83 (95% CI, 1.34–2.51; p < 0.001). The occurrence of severe desaturation was also independently associated with hemodynamic tracheal intubation–associated events: adjusted odds ratio 2.16 (95% CI, 1.54–3.04; p < 0.001). Number of tracheal intubation attempts was also significantly associated with the frequency of moderate and severe desaturations (p < 0.001). Conclusions: In this large tracheal intubation quality improvement database, we found moderate and severe desaturation are reported among 19% and 13% of all tracheal intubation encounters. Moderate and severe desaturations were independently associated with the occurrence of adverse hemodynamic events. Future quality improvement interventions may focus to reduce desaturation events.
