OBJECTIVES:: To characterize the landscape of process of care and safety outcomes for tracheal intubation across pediatric intensive care units BACKGROUND:: Procedural process of care and safety outcomes of tracheal intubation across pediatric intensive care units has not been described. We hypothesize that the novel National Emergency Airway Registry for Children registry is a feasible tool to capture tracheal intubation process of care and outcomes. DESIGN:: Prospective, descriptive. SETTING:: Fifteen academic PICUs in North America. PATIENTS:: Critically ill children requiring tracheal intubation in PICUs. INTERVENTIONS:: Tracheal intubation quality improvement data were prospectively collected for all initial tracheal intubation in 15 PICUs from July 2010 to December 2011 using the National Emergency Airway Registry for Children tool with explicit site-specific compliance plans and operational definitions including adverse tracheal intubation associated events. MEASUREMENT AND MAIN RESULTS:: One thousand seven hundred fifteen tracheal intubation encounters were reported (averaging 1/3.4 days, or 1/86 bed days). Ninety-eight percent of primary tracheal intubation were successful; 86% were successful with less than or equal to two attempts. First attempt was by pediatric residents in 23%, pediatric critical care fellows in 41%, and critical care attending physicians in 13%: first attempt success rate was 62%, first provider success rate was 79%. The first method was oral intubation in 1,659 (98%) and nasal in 55 (2%). Direct laryngoscopy was used in 96%. Ninety percent of tracheal intubation were with cuffed tracheal tubes. Adverse tracheal intubation associated events were reported in 20% of intubations (n = 372), with severe tracheal intubation associated events in 6% (n = 115). Esophageal intubation with immediate recognition was the most common tracheal intubation associated events (n = 167, 9%). History of difficult airway, diagnostic category, unstable hemodynamics, and resident provider as first airway provider were associated with occurrence of tracheal intubation associated events. Severe tracheal intubation associated events were associated with diagnostic category and pre-existing unstable hemodynamics. Elective tracheal intubation status was associated with fewer severe tracheal intubation associated events. CONCLUSIONS:: National Emergency Airway Registry for Children was feasible to characterize PICU tracheal intubation procedural process of care and safety outcomes. Self-reported adverse tracheal intubation associated events occurred frequently and were associated with patient, provider, and practice characteristics.

ABSTRACT: Reductions in heart rate occur frequently in children during critical care intubation and are currently considered the gold standard for haemodynamic instability. Our objective was to estimate loss of heart beats during intubation and compare this to reduction in heart rate alone whilst testing the impact of atropine pre-medication. Data were extracted from a prospective 2-year cohort study of intubation ECGs from critically ill children in PICU/Paediatric Transport. A three step algorithm was established to exclude variation in pre-intubation heart rate (using a 95%CI limit derived from pre-intubation heart rate variation of the children included), measure the heart rate over time and finally the estimate the numbers of lost beats. 333 intubations in children were eligible for inclusion of which 245 were available for analysis (74%). Intubations where the fall in heart rate was less than 50 bpm were accompanied almost exclusively by less than 25 lost beats (n = 175, median 0 [0-1]). When there was a reduction of >50 bpm there was a poor correlation with numbers of lost beats (n = 70, median 42 [15-83]). During intubation the median number of lost beats was 8 - when atropine was not used compared to 0 [0-0] when atropine was used (p<0.001). A reduction in heart rate during intubation of <50 bpm reliably predicted a minimal loss of beats. When the reduction in heart rate was >50 bpm the heart rate was poorly predictive of lost beats. A study looking at the relationship between lost beats and cardiac output needs to be performed. Atropine reduces both fall in heart rate and loss of beats. Similar area-under-the-curve methodology may be useful for estimating risk when biological parameters deviate outside normal range.PLoS ONE 02/2014; 9(2):e86766.

ABSTRACT: Ventilator-associated pneumonia is the first or second most commonly diagnosed nosocomial infection in the PICU. Centers for Disease Control diagnostic criteria include clinical signs or symptoms in conjunction with a "positive" tracheal aspirate, defined as more than 10 colony-forming units/mL of bacteria on quantitative culture and/or more than 25 polymorphonuclear neutrophils per low-power field on Gram stain. We hypothesized that tracheal aspirate cultures and Gram stains would not correlate with clinical signs and symptoms and would therefore not distinguish between colonization and infection. Prospective observational study. PICU in an academic tertiary care center. Children intubated more than 48 hours. Sequential tracheal aspirate quantitative cultures and Gram stains in conjunction with daily collection of concordant clinical signs and symptoms. Time since intubation correlated strongly (p < 0.001) with the proportion of positive (> 10 colony-forming units/mL) tracheal aspirate quantitative cultures, but Centers for Disease Control-defined clinical signs or symptoms of ventilator-associated pneumonia, either singly or in combination, did not. Use of in-line suction catheters versus new, sterile catheters to obtain tracheal aspirates was associated with significantly greater proportion of positive tracheal aspirate bacterial cultures (p < 0.001). Most subjects had more than 25 polymorphonuclear neutrophils per low-power field on Gram stain; polymorphonuclear neutrophils on Gram stain correlated with positive bacterial culture (p = 0.04). Seventy-seven percent of the bacterial isolates detected in positive quantitative cultures were "pathogens." Antibiotic use at the time tracheal aspirates were obtained was associated with a lower frequency of positive quantitative cultures only with antibiotic regimens that included cefepime. Positive bacterial cultures of tracheal aspirates increase rapidly after intubation and usually include bacteria considered to be pathogens. Tracheal aspirate cultures and Gram stains do not appear to distinguish between infection and colonization. Antibiotic regimens that include cefepime decrease the frequency of positive cultures, but the significance of this is unclear.Pediatric Critical Care Medicine 03/2014; 15(4).
