Indications for prehospital intubation among severely injured children and the prevalence of significant traumatic brain injury among those intubated due to impaired level of consciousness.

BACKGROUND: Prehospital endotracheal intubation (PEI) of head injured children with impaired level of consciousness (LOC) aims to minimize secondary brain injury. However, PEI is controversial in otherwise stable children. We aimed to investigate the indications for PEI among pediatric trauma patients and the prevalence of clinically significant traumatic brain injury (csTBI) among those intubated solely due to impaired consciousness. METHODS: This is a multicenter retrospective cohort study of children who underwent PEI in northern Israel between January 2014 and December 2020 by six EMS agencies and were transported to two trauma centers in the area. We extracted data from EMS records and trauma registries. RESULTS: PEI was attempted in 179/986 (18.2%) patients and was successful in 92.2% of cases. Common indications for PEI were hypoxemia not corrected by supplemental oxygen (n = 30), traumatic cardiac arrest (n = 16), and facial injury compromising the airway (n = 13). 112 patients (62.6%) were intubated solely due to impaired or deteriorating LOC. Among these patients, 68 (62.4%) suffered csTBI. The prevalence of csTBI among those with field Glasgow Coma Scale (GCS) of 3, 4-8, and > 8 was 81.4%, 55.8%, and 28.6%, respectively (p < 0.001). Among children ≤ 10 years old intubated due to impaired LOC, 50% had csTBI. CONCLUSION: Impaired LOC is a major indication for PEI. However, a significant proportion of these patients do not suffer csTBI. Older age and lower pre-intubation GCS are associated with more accurate field classification. Our data indicate that further investigation and better characterization of patients who may benefit from PEI is necessary.

Malignant pertussis in infants: factors associated with mortality in a multicenter cohort study.

BACKGROUND: Malignant pertussis (MP) affects young infants and is characterized by respiratory distress, perpetual tachycardia and hyperleukocytosis up to 50 G/l, leading to multiple organ failure and death in 75% of cases. Leukodepletion may improve prognosis. A therapeutic strategy based on leukodepletion and extracorporeal life support (ECLS) according to different thresholds of leucocytes has been proposed by Rowlands and colleagues. We aimed at identifying factors associated with death and assess whether the respect of the Rowlands' strategy is associated with survival. METHODS: We reviewed all MP infants hospitalized in eight French pediatric intensive care units from January 2008 to November 2013. All infants younger than 3 months of age, admitted for respiratory distress with a diagnosis of pertussis and WBC count ≥ 50 G/l were recorded. Evolution of WBC was analyzed and an optimal threshold for WBC growth was obtained using the ROC-curve method. Clinical and biological characteristics of survivors and non-survivors were compared. Therapeutic management (leukodepletion and/or ECLS) was retrospectively assessed for compliance with Rowlands' algorithm (indication and timing of specific treatments). RESULTS: Twenty-three infants were included. Nine of 23 (40%) died: they presented more frequently cardiovascular failure (100% vs 36%, p = 0.003) and pulmonary hypertension (PHT; 100% vs 29%, p = 0.002) than survivors and the median [IQR] WBC growth was significantly faster among them (21.3 [9.7-28] G/l/day vs 5.9 [3.0-6.8] G/l/day, p = 0.007). WBC growth rate > 12 G/l/day and lymphocyte/neutrophil ratio < 1 were significantly associated with death (p = 0.001 and p = 0.003, respectively). Ten infants (43%) underwent leukodepletion, and seven (30%) underwent ECLS. Management following Rowlands' strategy was associated with survival (100% vs 0%; p < 0.001, relative risk of death = 0.18, 95%-CI [0.05-0.64]). CONCLUSIONS: A fast leukocyte growth and leukocytosis with neutrophil predominance during acute pertussis infection were associated with death. These findings should prompt clinicians to closely monitor white blood cells in order to early identify infants at risk of fatal outcome during the course of malignant pertussis. Such an early signal in infants at high risk of death would increase feasibility of compliant care to Rowlands' strategy, with the expectation of a better survival.

Severe pediatric war trauma: A military-civilian collaboration from retrieval to repatriation.

BACKGROUND: Modern conflicts take a disproportionate and increasing toll on civilians and children. Since 2013, hundreds of Syrian children have fled to the Israeli border. Severely injured children were triaged for military airborne transport and brought to civilian trauma centers in Israel. After recovery, these patients returned to their homes in Syria.We sought to describe a unique model of a coordinated military-civilian response for the stabilization, transport, and in-hospital management of severe pediatric warzone trauma. METHODS: Prehospital and in-hospital data of all severe pediatric trauma casualties transported by military helicopters from the Syrian border were extracted. Data were abstracted from the electronic medical records of military and civilian medical centers' trauma registries. RESULTS: Sixteen critically injured children with a median age of 9.5 years (interquartile range [IQR], 6.5-11.5) were transported from the Syrian border to Level I and Level II trauma centers within Israel. All patients were admitted to intensive care units. Eight patients underwent lifesaving procedures during flight, 7 required airway management, and 5 required thoracostomy. The median injury severity score was 35 (IQR, 13-49). Seven laparotomies, 5 craniotomies, 3 orthopedic surgeries, and 1 skin graft surgery were performed. The median intensive care unit and hospital length of stay were 6 days (IQR, 3-16) and 34 days (IQR, 14-46), respectively. Fifteen patients survived to hospital discharge and returned to their families. CONCLUSION: The findings of this small cohort suggest the benefits of a coordinated military-civilian retrieval of severe pediatric warzone trauma. LEVEL OF EVIDENCE: Therapeutic, Level V.

Laryngeal mask airway as a rescue device for failed endotracheal intubation during scene-to-hospital air transport of combat casualties.

BACKGROUND: Advanced airway management of combat casualties during scene-to-hospital air transport is challenging. Because of the short transport time, flight physicians of the Israeli military airborne combat evacuation unit are approved for the use of a laryngeal mask airway (LMA) in the event of failed endotracheal intubation (ETI). The aim of this study was to assess the effectiveness of LMA use during scene-to-hospital transport of combat casualties in Israel. PATIENTS AND METHODS: A retrospective cohort analysis of all combat casualties treated with ETI during scene-to-hospital transport over a 3-year period was carried out. Successful LMA insertion was defined as satisfactory placement of the device on the basis of adequate chest expansion with bag-mask ventilation. RESULTS: The median flight time from scene to hospital was 13 min [interquartile range (IQR): 9-15 min]. Sixty-five casualties underwent ETI attempts, 47 successful and 18 failed. All 18 casualties who had failed ETI underwent LMA insertion as a rescue treatment. Six casualties suffered from traumatic brain injury, six had firearm injuries, two had blast injuries, and two had inhalational injuries. LMA insertion was successful in 16/18 (88.9%) casualties, 14 survived to hospital discharge, whereas two were declared dead upon hospital arrival. Two cases of LMA insertion were unsuccessful, but patients survived to hospital discharge. Among the 16 successful cases, the median oxygen saturation on scene-pickup before LMA insertion and on hospital-handover with LMA in place were 90% (IQR: 84-96%) and 98% (IQR: 96-99%), respectively (P<0.0001, the 95% confidence interval for difference between medians was 4-11). CONCLUSION: The findings of this study suggest that in the event of failed ETI, combat casualties can be treated effectively with LMA during a short scene-to-hospital transport time.

Multidrug-Resistant Pathogens in Hospitalized Syrian Children.

Since 2013, wounded and ill children from Syria have received treatment in Israel. Screening cultures indicated that multidrug-resistant (MDR) pathogens colonized 89 (83%) of 107 children. For 58% of MDR infections, the pathogen was similar to that identified during screening. MDR screening of these children is valuable for purposes of isolation and treatment.

Severe pertussis and hyperleukocytosis: is it time to change for exchange?

BACKGROUND: Pertussis is an important cause of infant death worldwide and continues to be a public health concern even in countries with high vaccination coverage. Severe (critical) pertussis with hyperleukocytosis is a severe form of the disease with up to 80% mortality rate. Attempts have been reported to reduce the white blood cell burden by exchange transfusion (ET) with conflicting conclusions. CASE REPORT: We report a case of critical pertussis in a neonate who was treated with ET, in view of a comprehensive literature review. RESULTS: The patient was discharged without any sequelae. CONCLUSION: ET should be considered in all infants suffering from critical pertussis and hyperleukocytosis, even in secondary care community hospitals.

Current advances in intraosseous infusion - a systematic review.

OBJECTIVES: To describe the advancement of Intraosseous (IO) infusion in the spectrum of resuscitative protocols and to provide a systematic review on currently used semi-automatic IO infusion devices. The specific question addressed was: "In patients undergoing resuscitation, does the use of semi-automatic IO infusion devices compared to manual needles influence IO placement success rate, time for IO placement, and ease-of-use and user preference?" METHODS: The electronic databases PubMed and Embase were searched for articles published from 1997 to 2010 using the search terms ("intraosseous") AND ("needle" or "device" or "technique") AND ("infusion" or "injection" or "access"). The Internet search engine Google Scholar was searched using the search term "intraosseous infusion device" to identify articles published in electronic journals, books, and scientific websites. Articles were included only if they compared at least two types of semi-automatic devices, or compared one or more semi-automatic device with one or more manual needles. Reviews, editorials, surveys, and case reports were excluded. RESULTS: The search strategy yielded 179 papers. Ten studies met full criteria for further review. Of these, two were LOE 1 (randomized controlled trials), one was LOE 2 (non-randomized, concurrent controls), one was LOE 3 (retrospective controls), and six were LOE 5 (simulation-based study). One of the six LOE 5 studies was a non-peer reviewed article. CONCLUSIONS: Only a few studies compared the performance of different types of IO infusion devices, most of them have a low level of evidence. These studies suggested a superiority of the battery-powered IO driver over manual needles, and other semi-automatic IO infuson devices.

Mushroom poisoning from species of genus Inocybe (fiber head mushroom): a case series with exact species identification.

BACKGROUND: Many species of the genus Inocybe (family Cortinariaceae, higher Basidiomycetes) are muscarine-containing mycorrhizal mushrooms, ubiquitous around the world. The few published reports on the poisonous Inocybe mushrooms are often limited by the inadequate identification of the species. The clinical course of patients with typical muscarinic manifestations, in whom Inocybe spp. was unequivocally identified, is reported. CASE SERIES: Between November 2006 and January 2008 14 consecutive patients with typical muscarinic syndrome after mushroom ingestion were recorded. The clinical manifestations included combinations of nausea, vomiting, diarrhea, abdominal pain, hypersalivation, diaphoresis, tachycardia, bradycardia, hypotension, lacrimation, blurred vision, miosis, tremor, restlessness, flushing, and syncope. Time to onset of toxicity ranged between 15 min and 2 h after consumption, 5 h in one patient. Treatment was supportive, including intravenous fluids, antiemetics, and 1 mg atropine intravenously. Full recovery ensued within 12 h. In all the cases, an expert mycologist unequivocally identified the leftovers of the consumed mushrooms as Inocybe fastigiata, Inocybe geophylla, and Inocybe patouillardii. CONCLUSION: In this case series of patients who ingested identified muscarine-containing mushrooms supportive treatment and atropine resulted in recovery in all cases.

Comparison of two mechanical intraosseous infusion devices: a pilot, randomized crossover trial.

INTRODUCTION: Administration of medications via the intraosseous (IO) route has proven to be a lifesaving procedure in critically ill or injured children. Two mechanical IO infusion devices have been approved for use in children, the spring-loaded IO infusion device (Bone Injection Gun, BIG) and the battery-powered IO infusion drill (EZ-IO). The objective of this pilot study was to compare the success rates for insertion and the ease-of-use of the two devices. PATIENTS AND METHODS: A randomized crossover study was conducted in a local paramedic training course with 29 paramedic students participating. Participants watched two videos describing the use of the two devices, followed by a demonstration on how to use each device on a turkey bone model. Then subjects were divided into two study groups: BIG-first or EZ-IO-first. Each participant performed one insertion attempt with each device independently. All attempts were filmed by a video camera. Successful placement was defined as the visualization of fluid flow from the marrow cavity. Following the study procedure, participants completed a two-item questionnaire recording their ranking of the ease-of-use of each device and their "first choice device". RESULTS: Participants had a significantly higher one-attempt success rate with the EZ-IO than with the BIG (28/29 vs 19/29, p=0.016), and selected the EZ-IO as their first choice (20/29). Participants of the EZ-IO-first group assessed the EZ-IO as easier to use than the BIG (p=0.0039). The subjects of the BIG-first group found no difference in the ease-of-use between the two devices (p=0.32). CONCLUSIONS: As tested by paramedic students on a turkey bone model, the EZ-IO demonstrated higher success rates than the BIG and was the preferred device. Future studies are planned to determine which of the two devices is more appropriate for obtaining IO access in the setting of paediatric emergencies.

Delayed hypersensitivity reaction from black henna tattoo manifesting as severe facial swelling.

We report on a 14-year-old boy who was presented to the emergency department with an acute swelling of the face and scalp 3 days after using a new hair dye. The patient had applied a black henna tattoo 1 year earlier. Patch testing revealed an allergy to the potent skin sensitizer paraphenylenediamine, a common ingredient of hair dyes and also found in black henna tattoo. It is important for emergency physicians to be aware of the possibility of a delayed type-IV hypersensitivity reaction from black henna tattoos manifesting as an acute contact dermatitis. These patients may have gross facial swelling but should not be treated for angioedema.

Enhancing patient safety during pediatric sedation: the impact of simulation-based training of nonanesthesiologists.

OBJECTIVE: To evaluate the impact of simulation-based education on patient safety during pediatric procedural sedation. DESIGN: A prospective, observational, single-blind, controlled study of pediatric procedural sedation outside the operating room. SETTING: Two university teaching hospitals in Israel. PARTICIPANTS: Nonanesthesiologists, with or without training in simulation-based education on patient safety, who routinely perform procedural sedation outside the operating room. These comprise full-time pediatricians practicing emergency medicine and a cohort of pediatric gastroenterologists. INTERVENTION: The study investigators used the internally developed, 9-criteria Sedation Safety Tool to observe and evaluate nonanesthesiologists who were trained in sedation safety and compared their performance with that of colleagues who did not receive similar training. OUTCOME MEASURE: For each of the 9 criteria on the evaluation form, odds ratios and 95% confidence intervals were calculated to compare the actions of the individuals in the 2 study groups. RESULTS: Thirty-two clinicians were evaluated. Half of the physicians were graduates of the simulation-based sedation safety course. Significant differences in performance pertaining to patient safety were found between those physicians who did and those who did not complete simulation-based training. CONCLUSIONS: Pediatric procedural sedations conducted by simulator-trained nonanesthesiologists were safer. The simulation-based sedation safety course enhanced physician performance during pediatric procedural sedation.
