Post-extubation dysphagia in pediatric trauma patients: a single-center case-series study.

We aimed to investigate whether ventilator support time influences the occurrence of dysphagia in pediatric trauma patients. This case-series study was conducted in a single pediatric emergency and critical care center from April 2012 to March 2022. Trauma patients aged < 16 years who underwent tracheal intubation were divided into two groups based on the occurrence of dysphagia within 72 h after extubation, and their data were analyzed. Tracheal intubation was performed in 75 pediatric trauma patients, and 53 of them were included in the analysis. A total of 22 patients had post-extubation dysphagia and head trauma. The dysphagia group tended to have more severe head injuries (Abbreviated Injury Scale (AIS) 4 [4-5] vs. 4 [0-4]; p < 0.05), a longer ventilator support time (7 days [4-11] vs. 1 day [1-2.5]; p < 0.05), and a longer length of hospital stay (27 days [18.0-40.3] vs. 11 days [10.0-21.0]; p < 0.05). Severe head trauma and a long duration of tracheal intubation may be risk factors for dysphagia in pediatric trauma patients. Therefore, early recognition of these risk factors could assist in treatment planning for speech-language pathologist intervention and nutritional routes of administration.

Oral to nasal endotracheal tube exchange using tracheal tube guide and video laryngoscope in a pediatric patient with facial burns: a case report.

BACKGROUND: Airway management in children with severe burns is difficult because of airway edema and prolonged duration of ventilatory management. There is insufficient evidence to suggest that tracheostomy is beneficial for children. CASE PRESENTATION: A male child aged 1 year and 4 months was injured when he accidentally fell into a bathtub filled with boiling water. Furthermore, 85% of the burnt area, including the face and neck, consisted of second-degree burns; hence, oral tracheal intubation and resuscitative infusion were required. In this case, the patient was safely switched from oral to nasotracheal intubation using a tracheal tube guide and video laryngoscope, without the use of a bronchoscope, and ventilatory management could be continued for 2 weeks. CONCLUSION: Oral to nasal endotracheal tube exchange using a tracheal tube guide and video laryngoscope may be useful not only for pediatric burn patients but also for adult patients who need to be safely switched from oral to nasotracheal intubation.

Child requiring tracheostomy for removal of an airway foreign body at the tracheal bifurcation.

Airway foreign bodies are typically removed orally using a rigid bronchoscope. We present a rare case of a foreign body at the tracheal bifurcation that required removal via tracheostomy. A child turned pale while eating nuts and was suspected to have choked on a foreign body. CT revealed a foreign body at the tracheal bifurcation. As his respiratory condition was unstable, tracheal intubation and removal were attempted using a rigid bronchoscope. Tracheal obstruction during oral removal resulted in respiratory failure and bradycardia. Following emergency tracheostomy, the foreign body was removed via the tracheal stoma after his respiratory condition stabilised. The patient was discharged 21 days later without neurological sequelae. To avoid hypoxaemia during airway foreign body removal, as in this case, assessing the size of the upper airway and foreign body is necessary. Tracheostomy and foreign body removal through the tracheal opening should be considered proactively.

Paediatric progressive primary tuberculosis.

A previously healthy 13-year-old Japanese girl with a BCG vaccination history and no tuberculosis (TB) exposure history presented to the hospital with mild dyspnea for 1 month and fever for 5 days. Computed tomography showed consolidation with a pleural effusion, obstructed left main bronchus with an air bronchogram, and traction bronchiectasis of the left upper lobe (Fig. 1A, B). No improvement was observed with ampicillin. Computed tomography on day 23 showed a new granular shadow in the right upper lobe (Fig. 1C). Despite a negative interferon-gamma release assay (IGRA) result, the sputum on day 55 was positive for acid-fast bacilli on a ZiehlNeelsen stain and Mycobacterium tuberculosis on polymerase chain reaction. A fourdrug antituberculous regimen was initiated and she recovered rapidly. TB exposure history, positive tuberculin skin test or IGRA, and typical imaging findings are the triad for primary TB diagnosis (Perez-Velez and Marais, 2012; Lewinsohn et al., 2017; Ahmed et al., 2020). In pediatric primary TB, consolidation may be present and can be misdiagnosed as bacterial pneumonia; however, massive consolidation is rare (GriffithRichards et al., 2007). Primary pulmonary TB should be considered in children with lung consolidation that is unresponsive to antibiotics, despite negative IGRA and TB exposure history.

Simplified Clinical Decision Rule Using Clinically Important Events for Risk Prediction in Pediatric Head Injury: A Retrospective Cohort Study.

Computed tomography (CT) scans are useful for confirming head injury diagnoses. However, there is no standard clinical decision rule (CDR) for determining the need for CT scanning in pediatric patients with head injuries. We developed a CDR and conducted a retrospective cohort study to evaluate its diagnostic accuracy in identifying children with clinically important traumatic brain injury (ciTBI). We selected predictors based on three existing CDRs: CATCH, CHALICE, and PECARN. Of the 2569 eligible patients, 645 (439 (68%) boys, median age: five years) were included in this study. In total, 59 (9%) patients showed ciTBI, and 129 (20%) were admitted to hospital. The novel CDR comprised six predictors of abnormal CT findings. It had a sensitivity of 79.5% (95% confidence interval (CI): 65.5-89.0%) and a specificity of 50.9% (95% CI: 48.9-52.3%). The area under the receiver-operating characteristic curve (0.72, 95% CI: 0.67-0.77) was non-inferior to those of CATCH, CHALICE, and PECARN (0.71, 95% CI: 0.66-0.77; 0.67, 95% CI: 0.61-0.74; and 0.69, 95% CI: 0.64-0.73, respectively; p = 0.57). The novel CDR was statistically noninferior in diagnostic accuracy compared to the three existing CDRs. Further development and validation studies are needed before clinical application.

Transcatheter arterial embolisation is efficient and safe for paediatric blunt torso trauma: a case-control study.

BACKGROUND: It remains unclear whether transcatheter arterial embolisation (TAE) is as safe and effective for paediatric patients with blunt torso trauma as it is for adults in Japan, owing to few trauma cases and sporadic case reports. The study aimed to compare the efficacy and safety of TAE performed in paediatric (age ≤ 15 years) and adult patients with blunt torso trauma. METHODS: This was a single-centre, retrospective chart review study that included blunt torso trauma patients who underwent TAE in the trauma centre from 2012 to 2017. The comparative study was carried out between a 'paediatric patient group' and an 'adult patient group'. The outcome measures for TAE were the success of haemorrhage control and complications and standardised mortality ratio (SMR). RESULTS: A total of 504 patients with blunt torso trauma were transported to the trauma centre, out of which 23% (N = 114) with blunt torso trauma underwent TAE, including 15 paediatric and 99 adult patients. There was no significant difference between the use of TAE in paediatric and adult patients with blunt torso trauma (29% vs 22%, P = .221). The paediatric patients' median age was 11 years (interquartile ranges 7-14). The predicted mortality rate and SMR for paediatric patients were lower than those for adult patients (18.3% vs 25.9%, P = .026, and 0.37 vs 0.54). The rate of effective haemorrhage control without repeated TAE or additional surgical intervention was 93% in paediatric patients, which was similar to that in adult patients (88%). There were no complications in paediatric patients at our centre. There were no significant differences in the proportion of paediatric patients who underwent surgery before TAE or urgent blood transfusion (33% vs 26%, P = .566, or 67% vs 85%, P = .084). CONCLUSIONS: It is possible to provide an equal level of care related to TAE for paediatric and adult patients as it relates to TAE for blunt torso trauma with haemorrhage in the trauma centre. Alternative haemorrhage control procedures should be established as soon as possible whenever the patients reach a haemodynamically unstable state.

Cardiopulmonary failure as a result of brainstem encephalitis caused by enterovirus D68.

Enterovirus D68 (EV-D68) causes respiratory illnesses such as pneumonia, and has been reported to cause acute flaccid myelitis. Enterovirus A71 (EV-A71) is known to cause cardiopulmonary failure due to brainstem encephalitis, but there have been few reports of these conditions being associated with EV-D68. Outbreaks of EV-D68 infection have occurred in the USA, Canada, Europe and Asia. Clinical management is largely supportive and there are no specific antivirals available. The case patient, a 4-year-old girl, had cardiopulmonary failure due to brainstem encephalitis. EV-D68 was isolated from a throat swab. On admission, she had cardiopulmonary failure, which required intensive care using a ventilator and inotropic agents. Her cardiac function improved, but she had residual bulbar paralysis and limb weakness, which resolved over a 6-month period. This case confirms that EV-D68, may cause severe illness due to brainstem encephalitis, similar to that caused by EV-A71.

Effects of establishing a trauma center on the mortality rate among injured pediatric patients in Japan.

INTRODUCTION: It remains unclear whether trauma centers are effective for the treatment of injured pediatric patients. The aim of this study was to evaluate children's mortality before and after the establishment a trauma center by using standard mortality ratios (SMR) and a modified observed-expected chart. METHODS: This was a single center, retrospective chart review study that included injured pediatric patients (age <16 years) who were transported to our trauma center by the emergency medical services from 2012 to 2016 in Japan. RESULTS: Our study included 143 subjects: 45 (31%) were preschoolers aged < 6 years, and 43 (30%) had an injury severity score (ISS) ≥ 16. After the trauma centers established, the number of patients increased (70% increase per month), as did the number of the patients with an ISS of 41-75. The percentage of indirect transportations was significantly higher in the trauma center than in the non-trauma center (49% vs. 28%; p < 0.05). The SMR was significantly lower in the trauma-center than in the non-trauma center (0.461 vs. 0.589; p < 0.05). The mean value of the modified observed-expected chart was significantly higher in the trauma-center than in the non-trauma center (4.6 vs. 2.3; p < 0.05). For the patients who were directly transferred to our center, the transfer distance was greater in the trauma-center than in the non-trauma center (6.8 vs. 6.2 km; p < 0.05). The time interval from hospital admission to initiation of computed tomography (15.5 vs. 33 minutes; p < 0.05) and to definitive care (44 vs. 64.5 minutes; p < 0.05) decreased in the after group compared to the non-trauma center. CONCLUSIONS: The results of our study revealed that the centralization of pediatric injured pediatric patients in trauma centers improved the mortality rate in this population in Japan.

Successful Management of Airway and Esophageal Foreign Body Obstruction in a Child.

Foreign body asphyxia is a serious clinical problem with high morbidity and mortality rates. It is relatively common among children, especially those younger than 3 years, because they have a high risk of aspirating foreign bodies owing to their tendency to place objects in their mouth and lack of a well-developed swallowing reflex. Moreover, the neurologic outcome after out-of-hospital cardiac arrests (OHCA) in pediatric patients remains generally poor. Here, we report an unusual pediatric case of asphyxial OHCA caused by foreign bodies obstructing the airway, complicating esophageal foreign body, with a neurologically favorable outcome. This case highlights the importance of adequate treatment for pediatric patients with OHCA, as well as the prompt and efficient management for pediatric patients with foreign bodies obstructing the airway and esophagus.

Introduction of Pediatric Physiological and Anatomical Triage Score in Mass-Casualty Incident.

BACKGROUND: Triage has an important role in providing suitable care to the largest number of casualties in a disaster setting, but there are no secondary triage methods suitable for children. This study developed a new secondary triage method named the Pediatric Physiological and Anatomical Triage Score (PPATS) and compared its accuracy with current triage methods. METHODS: A retrospective chart review of pediatric patients under 16 years old transferred to an emergency center from 2014 to 2016 was performed. The PPATS categorized the patients, defined the intensive care unit (ICU)-indicated patients if the category was highest, and compared the accuracy of prediction of ICU-indicated patients among PPATS, Physiological and Anatomical Triage (PAT), and Triage Revised Trauma Score (TRTS). RESULTS: Among 137 patients, 24 (17.5%) were admitted to ICU. The median PPATS score of these patients was significantly higher than that of patients not admitted to ICU (11 [IQR: 9-13] versus three [IQR: 2-4]; P<.001). The optimal cut-off value of the PPTAS was six, yielding a sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 95.8%, 86.7%, 60.5%, and 99.0%. The area under the receiver-operating characteristic curve (AUC) was larger for PPTAS than for PAT or TRTS (0.95 [95% CI, 0.87-1.00] versus 0.65 [95% CI, 0.58-0.72]; P<.001 and 0.79 [95% CI, 0.69-0.89]; P=.003, respectively). Regression analysis showed a significant association between the PPATS and the predicted mortality rate (r2=0.139; P<.001), ventilation time (r2=0.320; P<.001), ICU stay (r2=0.362; P<.001), and hospital stay (r2=0.308; P<.001). CONCLUSIONS: The accuracy of PPATS was superior to other methods for secondary triage of children. Toida C , Muguruma T , Abe T , Shinohara M , Gakumazawa M , Yogo N , Shirasawa A , Morimura N .
