Early cerebral perfusion pressure augmentation with phenylephrine after traumatic brain injury may be neuroprotective in a pediatric swine model.

OBJECTIVE: Cerebral perfusion pressure<40 mm Hg following pediatric traumatic brain injury has been associated with increased mortality independent of age, and current guidelines recommend maintaining cerebral perfusion pressure between 40 mm Hg-60 mm Hg. Although adult traumatic brain injury studies have observed an increased risk of complications associated with targeting a cerebral perfusion pressure>70, we hypothesize that targeting a cerebral perfusion pressure of 70 mm Hg with the use of phenylephrine early after injury in the immature brain will be neuroprotective. DESIGN: Animals were randomly assigned to injury with a cerebral perfusion pressure of 70 mm Hg or 40 mm Hg. Diffuse traumatic brain injury was produced by a single rapid rotation of the head in the axial plane. Cerebral microdialysis, brain tissue oxygen, intracranial pressure, and cerebral blood flow were measured 30 min-6 hrs postinjury. One hour after injury, cerebral perfusion pressure was manipulated with the vasoconstrictor phenylephrine. Animals were euthanized 6 hrs posttraumatic brain injury, brains fixed, and stained to assess regions of cell injury and axonal dysfunction. SETTING: University center. SUBJECT: Twenty-one 4-wk-old female swine. MEASUREMENTS AND MAIN RESULTS: Augmentation of cerebral perfusion pressure to 70 mm Hg resulted in no change in axonal dysfunction, but significantly smaller cell injury volumes at 6 hrs postinjury compared to cerebral perfusion pressure 40 (1.1% vs. 7.4%, p<.05). Microdialysis lactate/pyruvate ratios were improved at cerebral perfusion pressure 70 compared to cerebral perfusion pressure 40. Cerebral blood flow was higher in the cerebral perfusion pressure 70 group but did not reach statistical significance. Phenylephrine was well tolerated and there were no observed increases in serum lactate or intracranial pressure in either group. CONCLUSIONS: Targeting a cerebral perfusion pressure of 70 mm Hg resulted in a greater reduction in metabolic crisis and cell injury volumes compared to a cerebral perfusion pressure of 40 mm Hg in an immature swine model. Early aggressive cerebral perfusion pressure augmentation to a cerebral perfusion pressure of 70 mm Hg in pediatric traumatic brain injury before severe intracranial hypertension has the potential to be neuroprotective, and further investigations are needed.

The impact of 24-hr, in-hospital pediatric critical care attending physician presence on process of care and patient outcomes*.

OBJECTIVE: Attending physicians are only required to provide in-hospital coverage during daytime hours in many pediatric intensive care units. An in-hospital 24-hr pediatric intensive care unit attending coverage model has been increasingly popular, but the impact of 24-hr, in-hospital attending coverage on care processes and outcomes has not been reported. We compared processes of care and outcomes before and after the implementation of a 24-hr in-hospital pediatric intensive care unit attending physician model. DESIGN: Retrospective comparison of before and after cohorts. SETTING: A single large, academic tertiary medical/surgical pediatric intensive care unit. PATIENTS: : Pediatric intensive care unit admissions in 2000-2006. INTERVENTION: Transition to 24-hr from 12-hr in-hospital pediatric critical care attending physician coverage model in January 2004. MEASUREMENTS AND MAIN RESULTS: A total of 18,702 patients were admitted to intensive care unit: 8,520 in 24 hrs; 10,182 in 12 hrs. Duration of mechanical ventilation was lower (median 33 hrs [interquartile range 12-88] vs. 48 hrs [interquartile range 16-133], adjusted reduction of 35% [95% confidence interval 25%-44%], p < .001) and intensive care unit length of stay was shorter (median 2 days [interquartile range 1-4] vs. 2 days [interquartile range 1-5], adjusted p < .001) for 24 hr vs. 12 hr coverage. The reduction in mechanical ventilation hours was similar when noninvasive, mechanical ventilation was included in ventilation hours (median 42 hrs vs. 56 hrs, adjusted reduction in ventilation hours: 33% [95% confidence interval 20-45], p < .001). Intensive care unit mortality was not significantly different (2.2% vs. 2.5%, adjusted p =.23). These associations were consistent across daytime and nighttime admissions, weekend and weekday admissions, and among subgroups with higher Pediatric Risk of Mortality III scores, postsurgical patients, and histories of previous intensive care unit admission. CONCLUSIONS: Implementation of 24-hr in-hospital pediatric critical care attending coverage was associated with shorter duration of mechanical ventilation and shorter length of intensive care unit stay. After accounting for potential confounders, this finding was consistent across a broad spectrum of critically ill children.

Characterization of tracheal intubation process of care and safety outcomes in a tertiary pediatric intensive care unit.

OBJECTIVE: To characterize tracheal intubation process of care and safety outcomes in a large tertiary pediatric intensive care unit using a pediatric adaptation of the National Emergency Airway Registry. Variances in process of care and safety outcome of intubation in the pediatric intensive care unit have not been described. We hypothesize that tracheal intubation is a common but high-risk procedure and that the novel pediatric adaptation of the National Emergency Airway Registry is a feasible tool to capture variances in process of care and outcomes. DESIGN: Prospective descriptive study. SETTING: A single 45-bed tertiary noncardiac pediatric intensive care unit in a large university-affiliated children's hospital. PATIENTS: Critically ill children who required intubation in the pediatric intensive care unit. INTERVENTIONS: Airway management data were prospectively collected for all initial airway management from July 2007 through September 2008 using the National Emergency Airway Registry tool tailored for pediatric application with explicit operational definitions. MEASUREMENT AND MAIN RESULTS: One hundred ninety-seven initial intubation encounters were reported (averaging one every 2.3 days). The first course intubation method was oral intubation in 181 (91.9%) and nasal in 16 (9.1%). Unwanted tracheal intubation-associated events were frequently reported (n = 38 [19.3%]), but severe tracheal intubation-associated events were rare (n = 6 [3.0%]). Esophageal intubation with immediate recognition was the most common tracheal intubation-associated event (n = 22). Desaturation <80% was reported in 51 of 183 (27.7%) and more than two intubation attempts in 30 of 196 (15.3%), both associated with occurrence of a tracheal intubation-associated event (p < .001, p = .001, respectively). Interestingly, patient age, history of difficult airway, and first attempt by resident were not associated with tracheal intubation-associated events. CONCLUSIONS: Unwanted tracheal intubation-associated events occurred frequently, but severe tracheal intubation-associated events were rare. Our novel registry can be used to describe the pediatric intensive care unit tracheal intubation procedural process of care and safety outcomes.

Development of an instrument for a primary airway provider's performance with an ICU multidisciplinary team in pediatric respiratory failure using simulation.

OBJECTIVE: To develop a scoring system that can assess the multidisciplinary management of respiratory failure in a pediatric ICU. METHODS: In a single tertiary pediatric ICU we conducted a simulation-based evaluation in a patient care area auxiliary to the ICU. The subjects were pediatric and emergency medicine residents, nurses, and respiratory therapists who work in the pediatric ICU. A multidisciplinary focus group with experienced providers in pediatric ICU airway management and patient safety specialists was formed. A task-based scoring instrument was developed to evaluate a primary airway provider's performance through Healthcare Failure Mode and Effect Analysis. Reliability and validity of the instrument were evaluated using multidisciplinary simulation-based airway management training sessions. Each session was evaluated by 3 independent expert raters. A global assessment of the team performance and the previous experience in training were used to evaluate the validity of the instrument. RESULTS: The Just-in-Time Pediatric Airway Provider Performance Scale (JIT-PAPPS) version 3, with 34 task-based items (14 technical, 20 behavioral), was developed. Eighty-five teams led by resident airway providers were evaluated by 3 raters. The intraclass correlation coefficient for raters was 0.64. The JIT-PAPPS score correlated well with the global rating scale (r = 0.71, P < .001). Mean total scores across the teams were positively associated with resident previous training participation (ß coefficient 7.1 ± 0.9, P < .001), suggesting good validity of the scale. CONCLUSIONS: A task-based scoring instrument for a primary airway provider's performance with a multidisciplinary pediatric ICU team on simulated pediatric respiratory failure was developed. Reliability and validity evaluation supports the developed scale.

External validity of the pediatric cardiac quality of life inventory.

PURPOSE: The Pediatric Cardiac Quality of Life Inventory (PCQLI) is a disease-specific, health-related quality of life (HRQOL) measure for pediatric heart disease (HD). The purpose of this study was to demonstrate the external validity of PCQLI scores. METHODS: The PCQLI development site (Development sample) and six geographically diverse centers in the United States (Composite sample) recruited pediatric patients with acquired or congenital HD. Item response option variability, scores [Total (TS); Disease Impact (DI) and Psychosocial Impact (PI) subscales], patterns of correlation, and internal consistency were compared between samples. RESULTS: A total of 3,128 patients and parent participants (1,113 Development; 2,015 Composite) were analyzed. Response option variability patterns of all items in both samples were acceptable. Inter-sample score comparisons revealed no differences. Median item-total (Development, 0.57; Composite, 0.59) and item-subscale (Development, DI 0.58, PI 0.59; Composite, DI 0.58, PI 0.56) correlations were moderate. Subscale-subscale (0.79 for both samples) and subscale-total (Development, DI 0.95, PI 0.95; Composite, DI 0.95, PI 0.94) correlations and internal consistency (Development, TS 0.93, DI 0.90, PI 0.84; Composite, TS 0.93, DI 0.89, PI 0.85) were high in both samples. CONCLUSION: PCQLI scores are externally valid across the US pediatric HD population and may be used for multi-center HRQOL studies.

"Booster" training: evaluation of instructor-led bedside cardiopulmonary resuscitation skill training and automated corrective feedback to improve cardiopulmonary resuscitation compliance of Pediatric Basic Life Support providers during simulated cardiac arrest.

OBJECTIVE: To investigate the effectiveness of brief bedside "booster" cardiopulmonary resuscitation (CPR) training to improve CPR guideline compliance of hospital-based pediatric providers. DESIGN: Prospective, randomized trial. SETTING: General pediatric wards at Children's Hospital of Philadelphia. SUBJECTS: Sixty-nine Basic Life Support-certified hospital-based providers. INTERVENTION: CPR recording/feedback defibrillators were used to evaluate CPR quality during simulated pediatric arrest. After a 60-sec pretraining CPR evaluation, subjects were randomly assigned to one of three instructional/feedback methods to be used during CPR booster training sessions. All sessions (training/CPR manikin practice) were of equal duration (2 mins) and differed only in the method of corrective feedback given to participants during the session. The study arms were as follows: 1) instructor-only training; 2) automated defibrillator feedback only; and 3) instructor training combined with automated feedback. MEASUREMENTS AND MAIN RESULTS: Before instruction, 57% of the care providers performed compressions within guideline rate recommendations (rate >90 min(-1) and <120 min(-1)); 71% met minimum depth targets (depth, >38 mm); and 36% met overall CPR compliance (rate and depth within targets). After instruction, guideline compliance improved (instructor-only training: rate 52% to 87% [p .01], and overall CPR compliance, 43% to 78% [p < .02]; automated feedback only: rate, 70% to 96% [p = .02], depth, 61% to 100% [p < .01], and overall CPR compliance, 35% to 96% [p < .01]; and instructor training combined with automated feedback: rate 48% to 100% [p < .01], depth, 78% to 100% [p < .02], and overall CPR compliance, 30% to 100% [p < .01]). CONCLUSIONS: Before booster CPR instruction, most certified Pediatric Basic Life Support providers did not perform guideline-compliant CPR. After a brief bedside training, CPR quality improved irrespective of training content (instructor vs. automated feedback). Future studies should investigate bedside training to improve CPR quality during actual pediatric cardiac arrests.

Evaluation of multidisciplinary simulation training on clinical performance and team behavior during tracheal intubation procedures in a pediatric intensive care unit.

OBJECTIVE: Tracheal intubation in the pediatric intensive care unit is often performed in emergency situations with high risks. Simulation has been recognized as an effective methodology to train both technical and teamwork skills. Our objectives were to develop a feasible tool to evaluate team performance during tracheal intubation in the pediatric intensive care unit and to apply the tool in the clinical setting to determine whether multidisciplinary teams with a higher number of simulation-trained providers exhibit more proficient performance. DESIGN: Prospective, observational pilot study. SETTING: Single tertiary children's hospital pediatric intensive care unit. SUBJECTS: Pediatric and emergency medicine residents, pediatric intensive care unit nurses, and respiratory therapists from October 2007 to June 2008. INTERVENTIONS: A pediatric intensive care unit on-call resident, a pediatric intensive care unit nurse, and a respiratory therapist received simulation-based multidisciplinary airway management training every morning. An assessment tool for team technical and behavioral skills was developed. Independent trained observers rated actual intubations in the pediatric intensive care unit by using this tool. MEASUREMENTS AND MAIN RESULTS: For observer training, two independent raters (research assistants 1 and 2) evaluated a total of 53 training sessions (research assistant 1, 16; research assistant 2, 37). The correlation coefficient with the facilitator expert (surrogate standard) was .73 for research assistant 1 and .88 for research assistant 2 (p ≤ .001 for both) in the total score, .84 for research assistant 1 and .77 for research assistant 2 (p < .001 for both) in the technical domain, and .63 for research assistant 1 (p = .009) and .84 for research assistant 2 (p < .001) in the behavioral domain. The correlation coefficient was lower in video-based observation (.62 vs. .88, on-site). For clinical observation, 15 intubations were observed in real time by raters. The performance by a team with two or more simulation-trained members was rated higher compared with the team with fewer than two trained members (total score: 127 ± 6 vs. 116 ± 9, p = .012, mean ± sd). CONCLUSIONS: It is feasible to rate the technical and behavioral performance of multidisciplinary airway management teams during real intensive care unit intubation events by using our assessment tool. The presence of two or more multidisciplinary simulation-trained providers is associated with improved performance during real events.

Folic acid enhances early functional recovery in a piglet model of pediatric head injury.

For stroke and spinal cord injury, folic acid supplementation has been shown to enhance neurodevelopment and to provide neuroprotection. We hypothesized that folic acid would reduce brain injury and improve neurological outcome in a neonatal piglet model of traumatic brain injury (TBI), using 4 experimental groups of 3- to 5-day-old female piglets. Two groups were intubated, anesthetized and had moderate brain injury induced by rapid axial head rotation without impact. One group of injured (Inj) animals received folic acid (Fol; 80 µg/kg) by intraperitoneal (IP) injection 15 min following injury, and then daily for 6 days (Inj + Fol; n = 7). The second group of injured animals received an IP injection of saline (Sal) at the same time points (Inj + Sal; n = 8). Two uninjured (Uninj) control groups (Uninj + Fol, n = 8; Uninj + Sal, n = 7) were intubated, anesthetized and received folic acid (80 µg/kg) or saline by IP injection at the same time points as the injured animals following a sham procedure. Animals underwent neurobehavioral and cognitive testing on days 1 and 4 following injury to assess behavior, memory, learning and problem solving. Serum folic acid and homocysteine levels were collected prior to injury and again before euthanasia. The piglets were euthanized 6 days following injury, and their brains were perfusion fixed for histological analysis. Folic acid levels were significantly higher in both Fol groups on day 6. Homocysteine levels were not affected by treatment. On day 1 following injury, the Inj + Fol group showed significantly more exploratory interest, and better motor function, learning and problem solving compared to the Inj + Sal group. Inj + Fol animals had a significantly lower cognitive composite dysfunction score compared to all other groups on day 1. These functional improvements were not seen on day 4 following injury. Axonal injury measured by ß-amyloid precursor protein staining 6 days after injury was not affected by treatment. These results suggest that folic acid may enhance early functional recovery in this piglet model of pediatric head injury. This is the first study to describe the application of complex functional testing to assess an intervention outcome in a swine model of TBI.

Effect of just-in-time simulation training on tracheal intubation procedure safety in the pediatric intensive care unit.

BACKGROUND: Tracheal intubation-associated events (TIAEs) are common (20%) and life threatening (4%) in pediatric intensive care units. Physician trainees are required to learn tracheal intubation during intensive care unit rotations. The authors hypothesized that "just-in-time" simulation-based intubation refresher training would improve resident participation, success, and decrease TIAEs. METHODS: For 14 months, one of two on-call residents, nurses, and respiratory therapists received 20-min multidisciplinary simulation-based tracheal intubation training and 10-min resident skill refresher training at the beginning of their on-call period in addition to routine residency education. The rate of first attempt and overall success between refresher-trained and concurrent non-refresher-trained residents (controls) during the intervention phase was compared. The incidence of TIAEs between preintervention and intervention phase was also compared. RESULTS: Four hundred one consecutive primary orotracheal intubations were evaluated: 220 preintervention and 181 intervention. During intervention phase, neither first-attempt success nor overall success rate differed between refresher-trained residents versus concurrent non-refresher-trained residents: 20 of 40 (50%) versus 15 of 24 (62.5%), P = 0.44 and 23 of 40 (57.5%) versus 18 of 24 (75.0%), P = 0.19, respectively. The resident's first attempt and overall success rate did not differ between preintervention and intervention phases. The incidence of TIAE during preintervention and intervention phases was similar: 22.0% preintervention versus 19.9% intervention, P = 0.62, whereas resident participation increased from 20.9% preintervention to 35.4% intervention, P = 0.002. Resident participation continued to be associated with TIAE even after adjusting for the phase and difficult airway condition: odds ratio 2.22 (95% CI 1.28-3.87, P = 0.005). CONCLUSIONS: Brief just-in-time multidisciplinary simulation-based intubation refresher training did not improve the resident's first attempt or overall tracheal intubation success.

National survey of pediatric critical care medicine fellowship clinical and research time allocation.

OBJECTIVE: Pediatric critical care medicine (PCCM) fellowship programs vary in the number of fellows per program and experiences offered. We evaluated whether program size and rotation distribution affect clinical and research time allocation. DESIGN: : We surveyed directors of all Accreditation Council of Graduate Medical Education-accredited PCCM training programs in 2006. MEASUREMENTS AND MAIN RESULTS: Forty-six of 60 (77%) responded. Twenty-seven programs (59%) have dedicated cardiac intensive care unit rotations (median 4 months, range 1-9). Median research time is 18 months (range 12-24). Median intensive care unit (ICU) clinical time over 3 years is 14 months (interquartile range 12.5-18). Programs with dedicated cardiac intensive care unit rotations have more total ICU time (16 months vs. 13 months, p = 0.0006), but not less research time (17.5 months vs. 18 months, p = 0.1), indicating fewer non-ICU experiences. Larger programs were less likely to have night call during research time and more likely to have in-hospital fellow call, but otherwise program size did not affect clinical time allocation. CONCLUSIONS: Data on clinical and research time allocation of U.S. PCCM fellowships can help program directors benchmark their program training time and content. Fellowship size and unit structure do not influence overall allocation of clinical and research time or night call, but impact the number of non-ICU rotations and elective exposures.

Neuron-specific enolase and S-100B are associated with neurologic outcome after pediatric cardiac arrest.

OBJECTIVE: To characterize the pattern of serum biochemical markers of central nervous system injury (neuron-specific enolase [NSE], S-100B, plasminogen activator inhibitor-1 [PAI-1]) after pediatric cardiac arrest and determine whether there is an association between biomarker concentrations and neurologic outcome. DESIGN: Prospective, observational study. SETTING: Urban, tertiary care children's hospital. PATIENTS: Cardiac arrest survivors, n = 35. INTERVENTIONS: Serial blood sampling, pediatric cerebral performance category, and standardized neurologic examination. MEASUREMENTS AND MAIN RESULTS: Serial serum NSE and S-100B concentrations over 96 hrs and PAI-1 at 24 hrs were measured in children (age <18 yrs) who had return of spontaneous circulation following cardiac arrest. Neurologic outcome was prospectively categorized as poor if the change in pre- to postarrest pediatric cerebral performance category was > or =2. Biomarker concentrations were compared between outcome groups and between survival groups using longitudinal analysis correcting for multiple comparisons. Median levels (25th, 75th percentiles) are reported. Receiver operating characteristic analyses were performed at all time points. Biomarker concentrations showed statistically significant differences. Of the 35 patients, neurologic outcomes were poor in 19, with 15 deaths. Median NSE concentrations differed by outcome when measured at > or =48 hrs, and by survival at > or =24 hrs. S-100B concentrations were not significantly associated with neurologic outcome. S-100B levels were associated with survival outcome at > or =48 hrs. PAI-1 levels were not significantly associated with either neurologic or survival outcomes. CONCLUSIONS: The timing, intensity, and duration of serum NSE and S-100B biomarker concentration patterns are associated with neurologic and survival outcomes following pediatric cardiac arrest. Serum NSE concentrations at > or =48 hrs are associated with neurologic outcome, whereas serum S-100B levels at > or =48 hrs are associated with survival. Prospective analysis of these markers may help to predict outcomes and guide postresuscitative therapies.

The Children's Hospital of Philadelphia's experience with donation after cardiac death.

OBJECTIVE: To describe our experience with pediatric donation after cardiac death. DESIGN: Retrospective chart review of all cases of donation after cardiac death from 1995 to 2005. SETTING: The Children's Hospital of Philadelphia pediatric intensive care unit. PATIENTS: Twelve patients who were pediatric organ donors after cardiac death. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Charts for 12 patients were located, and donation after cardiac death was confirmed. There were two females and ten males. Patient age ranged from 1 to 17 yrs (mean 8 yrs). Four patients had severe traumatic brain injury, and eight patients had hypoxic ischemic encephalopathy. The organs procured were 24 kidneys, eight livers, four lungs, and one pancreas. The organs transplanted were 23 kidneys, four livers, and one pancreas. Ten of 12 cases of withdrawal of life-sustaining support occurred in the operating room area; the other two occurred in the holding area and the postanesthesia care unit. Children received a wide range of medications at the time of extubation. No neuromuscular blockers were used. The time of extubation to time of death ranged from 4 mins to 30 mins, with a mean of 14.5 mins. Death was declared based on cardiac asystole confirmed by auscultation and transthoracic impedance, with organ procurement initiated 5 mins later. Regarding who initiated conversation about donation after cardiac death, nine cases were family initiated, one case was physician initiated, and in two there was a collaborative approach with the physician and representative from the organ procurement organization. Of the organs transplanted, all organs other than one kidney and one split liver graft were functioning at 1 yr post-transplant. CONCLUSIONS: Pediatric donation after cardiac death can be performed successfully; its impact on end-of-life care and bereavement needs further investigation.

Anticonvulsant medications in the pediatric emergency room and intensive care unit.

Seizures are common in pediatric emergency care units, either as the main medical issue or in association with an additional neurological problem. Rapid treatment prolonged and repetitive seizures or status epilepticus is important. Multiple anti-convulsant medications are useful in this setting, and each has various indications and potential adverse effects that must be considered in regard to individual patients. This review discusses new data regarding anticonvulsants that are useful in these settings, including fosphenytoin, valproic acid, levetiracetam, and topiramate. A status epilepticus treatment algorithm is suggested, incorporating changes from traditional algorithms based on these new data. Treatment issues specific to complex medical patients, including patients with brain tumors, renal dysfunction, hepatic dysfunction, transplant, congenital heart disease, and anticoagulation, are also discussed.

The voice advisory manikin (VAM): an innovative approach to pediatric lay provider basic life support skill education.

AIM: To determine the efficacy of immediate, standardized, corrective audio feedback training as supplied by the voice advisory manikin (VAM) compared to high quality standardized instructor feedback training for the initial acquisition of 1-rescuer lay provider pediatric BLS skills. MATERIALS AND METHODS: Lay care providers of hospitalized children 8-18 years were randomized to VAM (n=23) or standardized human instruction (SHI, n=27) training in one-rescuer pediatric BLS. After an identical video/instructor introduction to CPR and 20 min of training in their respective group, quantitative CPR psychomotor skill data was recorded during 3-min CPR testing epochs. All manikins used in training and testing sessions were identical in outside appearance and feel of doing CPR. The primary outcome measure was CPR psychomotor skill success defined prospectively as 70% correct chest compressions (CC) and ventilations (V). Subjects not attaining these success goals retrained for 5 min in their respective training group and were retested. Data analysis using student t-test and chi2-tests as appropriate. RESULTS: VAM trainees delivered more total CC/min (58.7+/-7.9 versus 47.6+/-10.5, p<0.001), correct CC/min (47.9+/-15.7 versus 31.2+/-16.0, p<0.001), total V/min (7.8+/-1.2 versus 6.4+/-1.4, p<0.001), and correct V/min (5.4+/-1.9 versus 3.1+/-1.6, p<0.001). Overall error rates per individual were lower in VAM trainees for chest compressions (18.1+/-23.2% versus 34.9+/-28.8%, p<0.03) and ventilations (32.0+/-19.7% versus 50.7+/-24.1%, p<0.005). More VAM (12/23, 52%) than SHI (1/26, 4%) trainees passed the initial skill tests (p

Retrospective analysis of the prognostic value of electroencephalography patterns obtained in pediatric in-hospital cardiac arrest survivors during three years.

OBJECTIVE: To test the hypothesis that electroencephalography has prognostic value in children after in-hospital cardiac arrest. DESIGN: Single-center, retrospective chart review. SETTING: Urban tertiary care children's hospital, January 2001 to July 2004. PATIENTS: Thirty-four consecutive children were identified from a registry of all patients resuscitated for cardiac arrest. Inclusion criteria were age >44 wks postmenstrual age to 18 yrs, survival after in-hospital cardiac arrest >24 hrs, and undergoing electroencephalography within 7 days after the cardiac arrest. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Prearrest, event, cardiopulmonary resuscitation, and postresuscitation variables were collected. Neurologic outcome was assessed by Pediatric Cerebral Performance Category (PCPC). Prearrest PCPC was estimated from chart review. Change in PCPC >1 or death between prearrest and time of hospital discharge was defined as poor neurologic outcome. Experts blinded to PCPC outcomes scored electroencephalographs from 1 (normal) to 5 (isoelectric). Sensitivity/specificity analysis and receiver operating characteristic curve were developed with each electroencephalography grade cutoff. Of 184 consecutive patients who had cardiac arrests in our registry, 107 survived >24 hrs, and 83 met study criteria. Thirty-four patients had electroencephalography within the first 7 days after the cardiac arrest. Among those, 16 (47%) patients had good neurologic outcome defined as no change in PCPC, and 18 (53%) died or had poor neurologic outcome. Univariate analysis showed that a higher electroencephalography score performed within 7 days was associated with poor neurologic outcome (p < .05). Positive predictive value of electroencephalography grade 4-5 for poor neurologic outcome was 90%, and negative predictive value of electroencephalography grade 1-2 for poor neurologic outcome was 91%. CONCLUSIONS: In a single-center consecutive case series, electroencephalography background patterns during the initial 7 days after in-hospital cardiac arrest were associated with neurologic outcome in children.

Brain tissue oxygen monitoring in pediatric patients with severe traumatic brain injury.

OBJECT: Intracranial pressure (ICP) and cerebral perfusion pressure (CPP) monitoring are fundamental to the management of severe traumatic brain injury (TBI). In adults, brain tissue oxygen monitoring (specifically PO2) and treatment have been shown to be safe additions to conventional neurocritical care and are associated with improved outcome. Brain tissue oxygen monitoring, however, has not been described in pediatric patients with TBI. In this report, the authors present preliminary experience with the use of ICP and PO2 monitoring in this population. METHODS: Pediatric patients (age <18 years) with severe TBI (Glasgow Coma Scale score <8) admitted to a Level 1 trauma center who underwent ICP and PO2 monitoring were evaluated. Therapy was directed at maintaining ICP below 20 mm Hg and age-appropriate CPP (> or =40 mm Hg). Data obtained in six patients (two girls and four boys ranging in age from 6-16 years) were analyzed. Brain tissue oxygen levels were significantly higher (p < 0.01) at an ICP of less than 20 mm Hg (PO2 29.29 +/- 7.17 mm Hg) than at an ICP of greater than or equal to 20 mm Hg (PO2 22.83 +/- 13.85 mm Hg). Significant differences (p < 0.01) were also measured when CPP was less than 40 mm Hg (PO2 2.53 +/- 7.98 mm Hg) and greater than or equal to 40 mm Hg (PO2 28.97 +/- 7.85 mm Hg). CONCLUSIONS: Brain tissue oxygen monitoring may be a safe and useful addition to ICP monitoring in the treatment of pediatric patients with severe TBI.

Review of bispectral index monitoring in the emergency department and pediatric intensive care unit.

OBJECTIVES: Sedation is a key component in the management of pediatric patients both in the pediatric emergency department (PED) and pediatric intensive care unit (PICU) for the treatment of pain and anxiety. Bispectral (BIS) index monitoring has been developed to help clinicians assess degree of hypnosis with anesthesia and may be useful in these environments. METHODS: Literature searches were conducted through MEDLINE for case series/reports, retrospective studies, and randomized trials that evaluate the validity and applications of BIS monitoring in the PED and PICU. RESULTS: Most of the studies are case series or retrospective studies in children. There are several prospective studies assessing validation of the monitor in children. Only a few studies have been performed that assess the influence of monitoring on outcomes in these environments. CONCLUSIONS: Bispectral values correlate fairly well with commonly used clinical sedation scores, but more variability in the scores has been observed at lighter levels of sedation. More studies are needed to assess the value of titrating sedation in the PED and PICU within specific BIS parameters to reduce morbidity and costs associated with over-sedation.

Shaken baby syndrome.

Unfortunately, head trauma caused by shaken baby syndrome is a common occurrence in infants and young children. The proper treatment and safety of these children can be enhanced by the nurse's ability to recognize features characteristic of this syndrome. If abuse is suspected, appropriate physicians, child-protective, and law-enforcement agencies should be notified immediately. Further research must be done to improve the understanding of the mechanisms associated with this disorder in the ultimate hope of improving the lives and outcome of infants and children.
