RESUMO

BACKGROUND: The present study explores the frequency, diagnostic approach, and therapeutic management of cerebral vasospasm in a cohort of children with moderate-to-severe traumatic and nontraumatic subarachnoid hemorrhage (SAH). METHODS: This was a single-center retrospective study performed over a 10-year period, from January 2010 to December 2019. Children aged from one month to 18 years who were admitted to the pediatric or adult intensive care unit with a diagnosis of SAH were eligible. Cerebral vasospasm could be suspected by clinical signs or transcranial Doppler (TCD) criteria (mean blood flow velocity > 120 cm/s or an increase in mean blood flow velocity by > 50 cm/s within 24 h) and then confirmed on cerebral imaging (with a reduction to less than 50% of the caliber of the cerebral artery). RESULTS: Eighty patients aged 8.6 years (3.3-14.8 years, 25-75th centiles) were admitted with an initial Glasgow Coma Scale score of 8 (4-12). SAH was nontraumatic in 21 (26%) patients. A total of 14/80 patients (18%) developed cerebral vasospasm on brain imaging on day 6 (5-10) after admission, with a predominance of nontraumatic SAH (12/14). The diagnosis of cerebral vasospasm was suspected on clinical signs and/or significant temporal changes in TCD monitoring (7 patients) and then confirmed on cerebral imaging. Thirteen of 14 patients with vasospasm were successfully treated using a continuous intravenous infusion of milrinone. The Pediatric Cerebral Performance Category score at discharge from the intensive care unit was comparable between children with vasospasm (score of 2 [1-4]) vs. children without vasospasm (score of 4 [2-4]) (p = 0.09). CONCLUSIONS: These findings indicate that cerebral vasospasm exists in pediatrics, particularly after nontraumatic SAH. The use of TCD and milrinone may help in the diagnostic and therapeutic management of cerebral vasospasm.

RESUMO

BACKGROUND: Many applications of transcranial Doppler (TCD) as a diagnosis or monitoring tool have raised interest in the last decades. It is important that clinicians know when and how to perform TCD in this population, what parameter to assess and monitor and how to interpret it. OBJECTIVE: This review aims to describe the emerging clinical applications of TCD in critically ill children excluding those suffering from trauma. METHODS: Databases Web of Science, Cochrane and PubMed were searched in May 2020. We considered all publications since the year 2000 addressing the use of TCD as a prognostic, diagnostic or follow-up tool in children aged 0 to 15 years admitted to intensive care or emergency units, excluding neonatology and traumatic brain injury. Two independent reviewers selected 82 abstracts and full-text articles from the 2011 unique citations identified at the outset. RESULTS: TCD provides crucial additional information at bedside about cerebrovascular hemodynamics. Many clinical applications include the diagnosis and management of various medical and surgical neurologic conditions (central nervous system infections, arterial ischemic stroke, subarachnoid hemorrhage and vasospasm, brain death, seizures, metabolic disease, hydrocephalus) as well as monitoring the impact systemic conditions on brain perfusion (hemodynamic instability, circulatory assistance). CONCLUSION: To conclude, TCD has become an invaluable asset for non-invasive neuromonitoring in critically ill children excluding those suffering from trauma. However, the scope of TCD remains unclearly defined yet and reference values in critically ill children are still lacking.

RESUMO

OBJECTIVES: The objective of this study was to assess whether the laterality of congenital diaphragmatic hernia (CDH) was a prognostic factor for neonatal survival. METHODS: This was a cohort study using the French national database of the Reference Center for Diaphragmatic Hernias. The principal endpoint was survival after hospitalization in intensive care. We made a comparative study between right CDH and left CDH by univariate and multivariate analysis. Terminations and stillbirths were excluded from analyses of neonatal outcomes. RESULTS: A total of 506 CDH were included with 67 (13%) right CDH and 439 left CDH (87%). Rate of survival was 49% for right CDH and 74% for left CDH (P < .01). Multivariate analysis showed two factors significantly associated with mortality: thoracic herniation of liver (OR 2.27; IC 95% [1.07-4.76]; P = .03) and lung-to-head-ratio over under expected (OR 2.99; IC 95% [1.41-6.36]; P < .01). Side of CDH was not significantly associated with mortality (OR 1.87; IC 95% [0.61-5.51], P = .26). CONCLUSION: Rate of right CDH mortality is more important than left CDH. Nevertheless after adjusting for lung-to-head-ratio and thoracic herniation of liver, right CDH does not have a higher risk of mortality than left CDH.

RESUMO

OBJECTIVE: To evaluate the status of congenital diaphragmatic hernia (CDH) management in France and to assess predictors of adverse outcomes. STUDY DESIGN: We reviewed the first-year outcome of all cases of CDH reported to the French National Register in 2011. RESULTS: A total of 158 cases were included. Of these, 83% (131) were prenatally diagnosed, with a mortality rate of 39% (44 of 112) for live born infants with a known outcome at hospital discharge. Mortality increased to 47% (60 of 128) including those with termination of pregnancy and fetal loss. This contrasts with the 7% (2 of 27) mortality rate of the patients diagnosed postnatally (P = .002). Mortality worsened with 1 prenatal marker of CDH severity (OR 3.38 [1.30-8.83] P = .013) and worsened further with 2 markers (OR 20.64 [5.29-80.62] P < .001). Classic postnatal risk factors of mortality such as side of hernia (nonleft P = .001), prematurity (P < .001), low birth weight (P = .002), and size of the defect (P < .001) were confirmed. Of the 141 live births (114 prenatal and 27 postnatal diagnosis) with known outcomes, 93 (67%) survived to hospital discharge, 68 (60%) with a prenatal diagnosis and 25 (93%) with a postnatal diagnosis. The median time to hospital discharge was 34 days (IQR, 19.25-62). Of these survivors, 71 (76%) were followed up for 1 year. CONCLUSIONS: Despite advances in management of CDH, mortality was high and associated with prenatal risk factors. Postnatally, severe persistent pulmonary hypertension was difficult to predict and presented persistent challenges in management.

RESUMO

PURPOSE: A high incidence of secondary adrenal insufficiency (AI) has been reported several months after a traumatic brain injury (TBI) in pediatric patients. Data from studies in adults suggest that AI may occur during the acute phase of TBI, with potential negative effects in the management of these vulnerable patients. The aim of this study was to describe the prevalence and the characteristics of AI in the acute phase of pediatric TBI. METHODS: Adrenal function was systematically evaluated in patients admitted to the pediatric intensive care unit following a TBI. Serial measurements of cortisol (9 samples) and adrenocorticotropic hormone (ACTH) were drawn from the second morning to the third morning post admission. Secondary AI was defined as all cortisols < 200 nmol/l (6 µg/dl) with ACTH < 12 pmol/l. RESULTS: Twenty-eight patients (2-15 years old) were evaluated. Secondary AI occurred in ten (36%) patients. AI was more frequent in patients with intracranial hypertension (p < 0.05). Patients with AI required longer mechanical ventilation (p < 0.05), and a non-significant trend for a higher Pediatric Logistic Organ Dysfunction score (p = 0.09) and greater norepinephrine dose (p = 0.11) was observed. CONCLUSIONS: Secondary AI is frequent during the acute phase of pediatric TBI, particularly when intracranial hypertension is present. Systematic assessment of pituitary function after TBI appears to be essential. A randomized clinical trial is warranted to evaluate the benefits of hormonal replacement therapy in TBI patients with AI.

RESUMO

AIM: To identify the baseline characteristics associated with suppurative complications in children with community-acquired primary pneumonia. METHODS: A retrospective study included all children from 28 days to 15 years old, who presented with community-acquired pneumonia at two French hospitals from 1995 to 2003. Complicated pneumonia was defined by the presence of empyema and/or lung abscess. RESULTS: Of 767 children with community-acquired pneumonia, 90 had suppurative complications: 83 cases of pleural empyema and seven cases of lung abscess. The mean prevalence of complicated pneumonia was 3% during the 1995-1998 period, and then steadily increased following a linear trend to reach 23% in 2003. Children with complicated pneumonia were older and had a longer symptomatic period preceding hospitalization. They were more likely to receive antibiotics, especially aminopenicillins (p < 0.01), and nonsteroidal anti-inflammatory drugs, especially ibuprofen (p < 0.001). In multivariable analysis, ibuprofen was the only preadmission therapy that was independently associated with complicated pneumonia [adjusted OR = 2.57 (1.51-4.35)]. CONCLUSION: This study confirms an association between the use of prehospital ibuprofen and suppurative pneumonic complications.
