Videographic Assessment of Pediatric Tracheal Intubation Technique During Emergency Airway Management.

OBJECTIVES: To examine technical aspects of pediatric tracheal intubation using video recording and to determine the association between tracheal intubation technique and procedural outcomes. DESIGN: Prospective observational study. SETTING: Emergency department resuscitation bay in single tertiary pediatric center. PATIENTS: Children undergoing emergent tracheal intubation under videorecorded conditions. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A published scoring tool for characterizing patient positioning, intubator kinematics, and adjunctive maneuvers during tracheal intubation was applied to videorecorded pediatric resuscitations when tracheal intubation was performed. Procedural outcomes were measured from video review. Seventy-one children underwent 109 tracheal intubation attempts with an overall first attempt success rate of 69% and a median laryngoscopy duration of 34 seconds (interquartile range, 24-47 s). A significant subset of tracheal intubation attempts were made with the patient's bed at a height below the level of intubator's umbilicus (61%), the patient in a supine position without head elevation (55%), the intubator bent at the waist to greater than 45° (66%), less than 1 cm of mouth opening by the intubator's right hand prior to laryngoscopy (46%), and with the intubator's face less than 12 inches away from the patient's mouth (65%). Adjunctive maneuvers were used in a minority of attempts (cricoid pressure 48%, external laryngeal manipulation 11%, retraction of the right corner of the patient's mouth 26%). On multivariate analysis, including controlling for patient age category and intubator background, retraction of the right corner of the patient's mouth by an assistant showed an independent association with successful tracheal intubation. No other technical aspects were associated with tracheal intubation success. CONCLUSIONS: Intubators commonly exhibited suboptimal technique during tracheal intubation such as bending deeply at the waist, having their eyes close to the patient's mouth, failing to widely open the patient's mouth, and not elevating the occiput in older children. Retraction of the right corner of the patient's mouth by an assistant during laryngoscopy and intubation was associated with TI success.

Tracheal intubation during pediatric cardiopulmonary resuscitation: A videography-based assessment in an emergency department resuscitation room.

OBJECTIVES: To describe procedural characteristics of tracheal intubation (TI) during cardiopulmonary resuscitation (CPR) in a pediatric emergency department, and to characterize interruptions in CPR associated with TI performance. METHODS: Retrospective single center case series. Resuscitations in a pediatric ED are videorecorded for quality improvement. Children who underwent TI while receiving chest compressions were eligible for inclusion. Intubations done by methods other than direct laryngoscopy were excluded. Background data included patient age and training background of intubator. Data on intubation attempts (success, laryngoscopy time) and chest compressions (interruptions, duration of pauses) were collected. RESULTS: Between December 2012 and February 2014, 32 patients had 59 TI attempts performed during CPR. Overall first attempt success at TI was 15/32 (47%); a median of 2 attempts were made per patient (range 1 to 4). Median laryngoscopy time was 47s (range 8-115s). 32/59 (54%) TI attempts had an associated interruption in CPR; the median interruption duration was 25s (range 3-64s). TI attempts without interruption in CPR were successful in 20/32 (63%) compared to 11/27 (41%) when CPR was paused (p=0.09). Laryngoscopy time was not significantly different between TI attempts with (47±21s) and without (47±26s; p=0.2) interruptions in compressions. 25/32 (78%) of pauses exceeded 10s in duration. CONCLUSIONS: TI during pediatric CPR results in significant interruptions in chest compressions. Procedural outcomes were not significantly different between attempts with and without compressions paused. In children receiving CPR, TI should be performed without pausing chest compressions.

Videographic assessment of cardiopulmonary resuscitation quality in the pediatric emergency department.

OBJECTIVE: To describe the adherence to guidelines for CPR in a tertiary pediatric emergency department (ED) where resuscitations are reviewed by videorecording. METHODS: Resuscitations in a tertiary pediatric ED are videorecorded as part of a quality improvement project. Patients receiving CPR under videorecorded conditions were eligible for inclusion. CPR parameters were quantified by retrospective review. Data were described by 30-s epoch (compression rate, ventilation rate, compression:ventilation ratio), by segment (duration of single providers' compressions) and by overall event (compression fraction). Duration of interruptions in compressions was measured; tasks completed during pauses were tabulated. RESULTS: 33 children received CPR under videorecorded conditions. A total of 650 min of CPR were analyzed. Chest compressions were performed at <100/min in 90/714 (13%) of epochs; 100-120/min in 309/714 (43%); >120/min in 315/714 (44%). Ventilations were 6-12 breaths/min in 201/708 (23%) of epochs and >12/min in 489/708 (70%). During CPR without an artificial airway, compression:ventilation coordination (15:2) was done in 93/234 (40%) of epochs. 178 pauses in CPR occurred; 120 (67%) were <10s in duration. Of 370 segments of compressions by individual providers, 282/370 (76%) were <2 min in duration. Median compression fraction was 91% (range 88-100%). CONCLUSIONS: CPR in a tertiary pediatric ED frequently met recommended parameters for compression rate, pause duration, and compression fraction. Hyperventilation and failure of C:V coordination were very common. Future studies should focus on the impact of training methods on CPR performance as documented by videorecording.
