Emergency whole-body CT scans in pediatric patients with trauma: patterns of injuries, yield of dual-phase scanning, and influence of second read on detection of injuries.

OBJECTIVES: To describe injury patterns in children with multiple trauma (MT), evaluate the yield of dual-phase whole-body CT (WBCT), and quantify missed injuries detected on second reading. METHODS: Remotely analyzed WBCT performed between 2011 and 2020 in 63 emergency departments on children admitted for MT were included. Second reading occurred within 24 h. Collected data included age, sex, mechanism, Injury Severity Score (ISS), radiologists' experience, time and duration of first reading, conclusion of both readings, and dosimetry. Melvin score assessed the clinical impact of missed injuries. RESULTS: Overall, 1114 patients were included, 1982 injuries were described in 662 patients (59.4%), 452/1114 (40.6%) WBCT were negative, and 314 (28.2%) patients had MT (≥ 2 body parts injured). The most frequent injuries were pulmonary contusions (8.3%), costal fractures (6.2%), and Magerl A1 vertebral fractures (4.9%). Overall, 151 injuries were missed in 92 (8.3%) patients. Independent predictors for missed injuries were age ≤ 4 years (p = 0.03), number of injured body parts ≥ 2 (p = 0.01), and number of injuries ≥ 3 (p < 0.001). Melvin score grade 3 lesions were found in 16/92 (17.4%) patients with missed injuries (1.4% of all WBCT), where only prolonged follow-up was necessary. Thirteen active bleeding or pseudoaneurysms were detected (0.7% of injuries). CONCLUSION: Injuries were diagnosed in 59.4% of patients. Double-reading depicted additional injuries in 8.3% of patients, significantly more in children ≤ 4 years, with ≥ 3 injuries or ≥ 2 injured body parts. As 28 % of patients had MT and 1.1% had active extravasation or pseudoaneurysm, indication for WBCT should be carefully weighted. KEY POINTS: • When performed as a first-line imaging evaluation, approximately 41% of WBCT for MT children were considered normal. • The three most common injuries were pulmonary contusions, costal fractures, and Magerl A1 vertebral fractures, but the patterns of traumatic injuries on WBCT depended on the children's age and the trauma mechanism. • The independent predictors of missed injuries were age ≤ 4 years, number of body parts involved ≥ 2, and total number of injuries ≥ 3.

How doctors communicated with parents in a neonatal intensive care: Communication and ethical issues.

AIM: Doctors have a moral and legal obligation to keep patients and their families informed, and this is an integral part of care. We explored the communication strategies used by doctors when they spoke to parents in a French neonatal intensive care unit (NICU). METHODS: This was a single-centre qualitative pilot study carried out from October 2015 to January 2016. We asked five doctors (three female) to audiotape their discussions with the parents of newborn infants during their NICU stay. The doctors' mean age was 43 years, and they had a mean of 14 years of NICU experience. Each discussion was subjected to thematic content analysis. RESULTS: We analysed 40 discussions carried out between doctors on 26 newborn infants. Five communication strategy themes emerged: building understanding, how the communication was constructed, the role of the doctor, and of the parents, in the overall care of the newborn infant and how the information given to the parents developed over time. CONCLUSION: Analysing the content of the information discussed with parents provided us with the opportunity to understand the communication and ethical issues surrounding the delivery of information in a NICU. This could be used to improve future discussions between doctors and parents.

Generalized arterial calcification of infancy with a novel ENPP1 mutation: a case report.

BACKGROUND: Generalized Arterial Calcification of Infancy (GACI) is a heritable ectopic mineralization disorder resulting in diffuse arterial calcifications and/or stenosis, mostly caused by mutations in the ENPP1 gene. Here we present a case report of GACI in a male infant with a new familial mutation of the ENPP1 gene and the clinical outcome after biphosphonates therapy. CASE PRESENTATION: The clinical presentation was characterized by a severe early-onset of hypertension refractory to multiple therapy. To investigate this atypical hypertension, a renal Doppler ultra-sonography was performed and diffuse echo-bright arteries were detected; then a low-dose whole-body computed tomography demonstrated extensive arterial calcifications, suggesting GACI. A novel homozygous mutation c.784A > G (p.Ser262Gly) was detected in the ENPP1 gene. The infant was administered four courses of bisphosphonates: arterial calcifications were found to decrease but severe refractory hypertension was persistent. Although GACI can be a rapidly fatal illness and frequently results in death in infancy, the patient was 24 months of age at the time of writing this report. CONCLUSIONS: Three points of interest: the first one is to remind clinicians of this rare and atypical etiology in neonates with severe hypertension and in fetuses with cardiomyopathy and non-immune hydrops fetalis. The second point is the identification of a novel mutation in the ENPP1 gene associated with a clinical presentation of GACI. The third point is the fairly favourable outcome of our patient after bisphosphonates therapy, with calcifications regression but not hypertension.

Comparison of a high-flow humidified nasal cannula to nasal continuous positive airway pressure in children with acute bronchiolitis: experience in a pediatric intensive care unit.

UNLABELLED: The objective of the current study is to compare the use of a nasal continuous positive airway pressure (nCPAP) to a high-flow humidified nasal cannula (HFNC) in infants with acute bronchiolitis, who were admitted to a pediatric intensive care unit (PICU) during two consecutive seasons. We retrospectively reviewed the medical records of all infants admitted to a PICU at a tertiary care French hospital during the bronchiolitis seasons of 2010/11 and 2011/12. Infants admitted to the PICU, who required noninvasive respiratory support, were included. The first noninvasive respiratory support modality was nCPAP during the 2010/11 season, while HFNC was used during the 2011/2012 season. We compared the length of stay (LOS) in the PICU; the daily measure of PCO2 and pH; and the mean of the five higher values of heart rate (HR), respiratory rate (RR), FiO2, and SpO2 each day, during the first 5 days. Thirty-four children met the inclusion criteria: 19 during the first period (nCPAP group) and 15 during the second period (HFNC group). Parameters such as LOS in PICU and oxygenation were similar in the two groups. Oxygen weaning occurred during the same time for the two groups. There were no differences between the two groups for RR, HR, FiO2, and CO2 evolution. HFNC therapy failed in three patients, two of whom required invasive mechanical ventilation, versus one in the nCPAP group. CONCLUSION: We did not find a difference between HFNC and nCPAP in the management of severe bronchiolitis in our PICU. Larger prospective studies are required to confirm these findings.

Pediatric intensive care unit follow-up: Thinking before acting.

OBJECTIVE: It is now well established that post-intensive care syndrome is frequent in critically ill children after discharge from the pediatric intensive care unit (PICU). Nevertheless, post-intensive care follow-up is highly heterogenous worldwide and is not considered routine care in many countries. The purpose of this viewpoint was to report the reflections of the French PICU society working group on how to implement post-PICU follow-up. METHODS: A working group was set up within the Groupe Francophone de Reanimation et d'Urgences Pédiatriques (GFRUP) to provide conceptual and practical guidance for developing post-PICU follow-up. The working group included psychologists, PICU physicians, physiotherapists, and nurses, from different French PICUs. Five virtual meetings have been held. RESULTS: First, we described in this work the objectives of the follow-up program and the population to be targeted. We also provided a framework to implement post-PICU follow-up in clinical practice. Finally, we detailed the potential obstacles and challenges to consider. CONCLUSION: Although implementing a post-PICU follow-up program is a challenge, the benefits could be significant for both patient and relatives, as well as for the health care professionals involved.

Echocardiography allows more accurate placement of peripherally inserted central catheters in low birthweight infants.

AIM: The use of plain radiographs provides limited information on the placement of peripherally inserted central catheters (PICCs). Moreover, changes in upper extremity positioning cause migration of the catheters in neonates. This study aimed to investigate the use of echocardiography for determining catheter tip position, compared with plain radiographs, in low birthweight (LBW) infants in a tertiary neonatal intensive care unit. METHODS: The study examined the placement of 109 catheters in 89 infants born between September 2010 and December 2012. The placement of these catheters was controlled by echocardiography, with the patient's shoulder in adduction and the elbow in flexion. The number of catheter tips, echocardiographically identified within the heart, was expressed as a percentage of the total catheters deemed to be well positioned on plain radiographs. RESULTS: The number of catheter tips that were echocardiographically identified within the heart was significant (25%, p < 0.001). Twenty-three catheters were repositioned to be outside of the heart, without any complications. CONCLUSION: This study demonstrated the value of echocardiography for identifying the positioning of catheter tips in LBW infants. Echocardiography, coupled with initial plain radiographs, should be the gold standard for assessing PICC tip positions in those infants.

European Pediatric Surgeons' Association Survey on the Use of Splenic Embolization in Blunt Splenic Trauma in Children.

INTRODUCTION: This article assesses (1) access to splenic embolization (SE), (2) indications for SE, and (3) post-embolization management in high-grade splenic trauma in children. MATERIALS AND METHODS: An online questionnaire was sent in 2021 to all members of European Pediatric Surgeons' Association. RESULTS: There were a total of 157 responses (50 countries, 83% academic hospitals). Among them, 68% have access to SE (SE) and 32% do not (nSE). For a hemodynamic stable patient with high-grade isolated splenic trauma without contrast extravasation (CE) on computed tomography (CT) scan, 99% SE and 95% nSE respondents use nonoperative management (NOM). In cases with CE, NOM decreases to 50% (p = 0.01) and 51% (p = 0.007) in SE and nSE centers, respectively. SE respondents report a significant reduction of NOM in stable patients with an associated spine injury requiring urgent surgery in prone position, both without and with CE (90 and 28%, respectively). For these respondents, in stable patients the association of a femur fracture only tends to decrease the NOM, both without and with CE (93 and 39%, respectively). There was no significant difference in NOM in group nSE with associated injuries with or without CE. After proximal SE with preserved spleen vascularization on ultrasound Doppler, 44% respondents prescribe antibiotics and/or immunizations. CONCLUSION: Two-thirds of respondents have access to SE. For SE respondents, SE is used even in stable patients when CE showed on initial CT scan and its use increased with the concomitant need for spinal surgery. There is currently a variation in the use of SE and antibiotics/immunizations following SE.

Sevoflurane for central catheter placement in neonatal intensive care: a randomized trial.

OBJECTIVE: To compare the efficacy and safety of sevoflurane deep sedation with glucose and nonnutritive sucking (GNNS) in reducing the duration of the procedure and in preventing pain-related effects during peripherally inserted central catheter (PICC) placement. BACKGROUND: PICC placement in neonatal intensive care is a delicate and stressful procedure that requires pain prevention. GNNS has been recommended in this situation but remain often inefficient. METHODS: We designed a randomized controlled study in a sixteen-bed pediatric and neonatal unit in a tertiary hospital. Fifty-nine neonates at >28 weeks of gestation with continuous positive airway pressure or invasive mechanical ventilation and requiring PICC placement were included. Patients were randomized to receive inhaled sevoflurane (IS) or glucose and non-nutritive sucking (GNNS). Procedural duration and conditions, hemodynamic and respiratory parameters, occurrence of movements and complications were compared (http://clinicaltrials.gov trial register no. NCT00420693). RESULTS: The two groups had similar demographics. There were no between-group differences in procedural duration (P = 0.84) despite greater immobility in IS group (P = 0.017). IS was also associated with fewer episodes of hypertension (P = 0.003), tachycardia (P < 0.001), and bradycardia (P = 0.02). Occurrences of hypotension were not different between the groups (P = 0.06). The GNNS group showed more desaturation during the 4 h after the procedure (P = 0.03). Complications during intensive care stay did not differ between groups. CONCLUSION: Inhaled sevoflurane does not make easier catheters placement but prevent pain-related symptoms. Because sevoflurane is responsible for hypotension, it requires careful monitoring and treatment adaptation.

Antimosquito precautions and medical chemoprophylaxis in French children with malaria.

BACKGROUND: France is the European country with the highest number of imported malaria cases (7,500 in 2000). The aim of this prospective study was to evaluate the nature and efficacy of prophylactic measures in children under 15 years of age referred for malaria. METHODS: Post travel questionnaires were given to the parents of malarial children in the emergency room. The study took place in two university hospitals in Marseilles, southern France, from August to October 2001. RESULTS: Eighty-eight children under 15 years of age were included in this 3-month period. Most of them had been infected in Comoro archipelago. Almost two-thirds used bed nets, but only 47% did so every night. Sprayed bed nets were used by 23%. Average compliances with cutaneous repellents, bedroom repellents and long-sleeved clothing were 32%, 24% and 26%, respectively. Air conditioners were uncommon. Only 22% of the children used chemoprophylaxis correctly, according to French recommendations. Five percent did not use any chemoprophylaxis, and 61% reported non recommended drug use. Although all the children traveled to chloroquine-resistant areas, chemoprophylaxis with mefloquine was less common than that with chloroquine + proguanil. No child fully complied with French recommendations concerning both anti mosquito measures and chemoprophylaxis. CONCLUSIONS: Insufficient use of antimalaria precautions by traveling families is associated with the high incidence of pediatric imported malaria in southern France. Travelers' education should be increased to allow the optimization of malaria prophylaxis.

Health-related quality of life and its determinants in children with a congenital diaphragmatic hernia.

BACKGROUND: The development of new therapeutics has led to progress in the early management of congenital diaphragmatic hernia (CDH) in pediatric intensive care units (PICU). Little is known about the impact on the quality of life (QoL) of children and their family. The aim of this study was to assess the impact of CDH treated according to the most recent concepts and methods outlined above on child survivors' QoL and their parents' QoL. PATIENTS AND METHODS: This study incorporated a cross-sectional design performed in two PICU (Marseille, France). Families of CDH survivors born between 1999 and 2008 were eligible. The following data were recorded: socio-demographics, antenatal history and delivery, initial hospitalization history. Self-reported data were collected by mail, including current clinical problems of the children (13-symptom list), children's QoL (Kidscreen-27 questionnaire), and parents' QoL (Short-Form 36 questionnaire). Children's QoL score was compared with controls and QoL of survivors of childhood leukemia. Parent's QoL was compared with controls. Non-parametric statistics were employed. RESULTS: Forty-two families agreed to participate and questionnaires were completed by 32 of them. Twenty-one children had a current clinical problems related to CDH. All the QoL scores of CHD survivors were significantly lower compared with controls. The physical well-being dimension was significantly higher for CHD survivors compared with survivors of childhood leukemia. Gastro-esophageal reflux at discharge, antenatal diagnosis, length of stay in the PICU, and neuropsychological and respiratory issues significantly impacted QoL scores of children. The parents of CHD survivors had significantly poorer score in emotional role dimension compared with controls. CONCLUSION: The impact of CDH on QoL seems to be important and must be understood by clinicians who treat these children and their parents.

Comparison of ultrasound and X-ray in determining the position of umbilical venous catheters.

OBJECTIVE: Thoraco-abdominal X-ray (TAX) is the most frequent used method to determine the route and tip position (TP) of umbilical venous catheters (UVCs). The aim of this study was to compare ability of TAX and ultrasonography (US) to determine UVC route and TP. PATIENTS AND METHODS: All neonates requiring UVC or admitted to our Paediatric and Neonatal Intensive Care with UVC were included in this prospective study. Catheter position was controlled by TAX and interpreted by the physician in charge of the patient. US examinations were performed by a paediatric radiologist blinded to TAX result. The UVC route (central or not central) and TP determined by each method were compared to the "actual UVC route and TP", as determined by senior paediatric radiologist and neonatologist referents joint interpretation of TAX and US results. RESULTS: Sixty-one UVCs were assessed in 60 neonates of mean gestational age of 34.7±4.2 weeks. To determine catheter route, sensitivity and specificity were respectively 96.4% and 93.9% for US and 92.8% and 78.8% for TAX. To determine catheter tip position, sensitivity and specificity were respectively 93.3% and 95.6% for US and 66.7% and 63.0% for TAX (p<0.001). Failure of TAX to define UVC tip position increased with birth weight (p<0.005). CONCLUSION: TAX and US are reliable in determining UVC route (central or not) but US examination is superior to TAX in determining UVC TP.

Hemidiaphragmatic paralysis in preterm neonates: a rare complication of peripherally inserted central catheter extravasation.

Unilateral diaphragmatic paralysis was diagnosed in 2 preterm neonates born at 29 and 25 weeks of gestation, respectively. In both instances, the pathophysiology was phrenic nerve injury after extravasation of parenteral nutrition fluid. Misplacement and infection were predisposing factors. Diaphragmatic movement analysis by time-motion-mode ultrasonography was helpful in achieving a diagnosis. The first neonate required a diaphragmatic placation, whereas the other infant was managed nonoperatively. These cases confirm a rare etiology of diaphragmatic paralysis and possible spontaneous recovery. In neonates with very low birth weight, general anesthesia and thoracic surgery may be associated with a high morbidity, suggesting that nonoperative medical treatment, when possible, is preferable if the neonate does not require supplemental oxygen.

Sevoflurane for central venous catheterization in non-intubated neonates.

OBJECTIVE: Sedation in neonates undergoing invasive prodedures as central venous catheterization (CVC) remains contro versial. Sevoflurane is an inhaled anesthetic whose periods of action and elimination are very short. The objective of this study was to evaluate the use of sevoflurane for sedation for central venous catheterization (CVC) in non-intubated neonates and preterms. METHODS: Thirty three (33) consecutive patients (range: 1-31 days old, 26 to 40 weeks GA, weighing 580 to 3200 g) were included over a 4 months period. Sevoflurane was progressively increased, until loss of consciousness and motor response to stimulation. FiO(2), heart rate (HR), mean arterial pressure (MAP), duration of the procedure and the ease of the procedure were recorded. RESULTS: HR was very stable, but MAP dropped significantly. No patient required intubation. The ease of the procedure was scored as average 13 times and excellent 20 times. CONCLUSION: The use of sevoflurane in neonates for CVC is feasible and achieve the goals of procedural sedation. The pharmacokinetic of sevoflurane enabled rapid adjustment of the depth of sedation. Sevoflurane appears to be a new agent at the disposal of neonatologists. Its use does not come without risks, especially for smaller preterms, which the treating clinician must anticipate.

Randomized controlled trial of sevoflurane for intubation in neonates.

BACKGROUND: Our aim was to determine whether sevoflurane can be used with safety and efficacy for anesthesia during intubation in term and preterm neonates in a prospective randomized-controlled nonblinded study in a tertiary neonatal intensive care unit. METHODS: Thirty-three neonates were randomly allocated to receive sevoflurane (inspired concentrations varying from 2% to 5%) or no medication (preoxygenation with 100% oxygen alone) before intubation. Minute by minute heart rate (HR), mean arterial blood pressure, SpO(2) and number of episodes of bradycardia (HR < 100 b.min(-1)) and desaturation (SpO(2) < 85% for >30 s) were noted from 5 min before to 10 min after intubation. Operator experience, ease and number of attempts were noted. RESULTS: No major adverse events were noted in the study group compared with the control group [hypotension (37.5% vs 37.5%, NS), number of desaturations [37.5% vs 44.5%, NS)]. Hypertension (25%, vs 56.3%P = 0.04) and incidence of bradycardias (8.3% vs 44.4%, P < 0.01) were greater in the control group. Intubation was easier in the study group: no movements: 95.5% vs 28% (P < 0.005); good glottis visualization: 73% vs 33% (P = 0.013). The failure rate was lower in the study group (25% vs 39%), but this difference was not statistically significant. CONCLUSION: Anesthesia for intubation with sevoflurane in neonates is well tolerated, even in the less mature. It facilitates the conditions for intubation and leads to fewer adverse events. Other studies are necessary to confirm these preliminary results.
