Central-line-associated bloodstream infections in a surgical paediatric intensive care unit: Risk factors and prevention with chlorhexidine bathing.

AIM: The aims of the study are to evaluate the impact of a 4% chlorhexidine (CHG4%) bathing on the occurrence of central-line-associated bloodstream infection (CLABSI) and to identify risk factors (RFs) for CLABSI in our population. This is a retrospective monocentric cohort study in the paediatric surgical intensive care unit at the Necker Enfants Malades Hospital, Paris, France. METHODS: All hospitalised patients with central venous catheters (CVCs) in 2015 were included. CHG4% bathing was prescribed in CLABSI high-risk patients, defined by the presence of exposition factors (EFs): constitutive or acquired immunosuppression, presence of an invasive medical device (IMD) and the carriage of Staphylococcus aureus. The overall 2015 CLABSI incidence rate was compared with 2014 CLABSI incidence rate (before CHG4% bathing). RESULTS: In all, 775 patients were analysed. Some 182 had at least one EF, and 49 received CHG4%. The incidence rates of CLABSI in 2014 and 2015 were, respectively, 6.1 and 2.3/1000 days CVC (P < 0.01). The presence of at least one EF was associated with the CLABSI's occurrence: odds ratio = 15.13 (95% confidence interval: 4.26-53.71; P < 0.0001), particularly acquired immunosuppression, IMD and S. aureus colonisation. Other RFs were age <1 year and carrying duration >16 days. CONCLUSIONS: This study showed a significant reduction in incidence of CLABSI after introduction of a targeted CHG4% bathing protocol. Presence of IMD, S. aureus colonisation, immunosuppression, age <1 year and carrying duration >16 days were CLABSI RFs. Regarding the literature, the presence of IMD seems to be underestimated in CLABSI prevention.

Hemodynamic Shock Caused by Tension Pneumoperitoneum in a 5-Year-Old Girl.

Tension pneumoperitoneum is a relatively rare occurrence in the pediatric population. However, tension pneumoperitoneum is associated with significant morbidity and mortality if it is not promptly diagnosed and treated. A 5-year-old girl was admitted to emergency department with abdominal pain. She was in shock, and the radiograph film of the abdomen revealed a voluminous tension pneumoperitoneum. Aggressive fluid challenges were performed in intensive care followed by urgent laparotomy. Primary abdominal compartment due to trapped gas caused a decreased venous return and visceral perfusion. In the absence of hemodynamic improvement after vascular filling, needle decompression was performed before surgery.

Extracorporeal Membrane Oxygenation Can Save Lives in Children With Heart or Lung Failure After Liver Transplantation.

The risk of cardiac or lung failure after liver transplantation (LT) is significant. In rare cases, the usual intensive care techniques fail to maintain organ oxygenation with a risk of multiorgan dysfunction. Although extracorporeal membrane oxygenation (ECMO) is a difficult and risky procedure, it can be proposed as life-saving. Four children with either acute pulmonary (three) or cardiac (one) failure after LT, and the criteria that decided the use of ECMO (level of ventilation and results, dosage of inotropic drugs, cardiac ultrasound, blood lactate) were retrospectively reported. These patients, 1-11 years old, were treated with either veno-arterial (three) or veno-venous (one) ECMO. Two experienced a full recovery, with 3 and 6 years of follow-up. Two died of systemic inflammatory response syndrome (SIRS) due to ECMO, and relapse of heart failure due to the underlying disease. Although our patients' survival was only 50%, we showed that ECMO can be useful in children after LT. It should be considered before the development of irreversible multiorgan failure.

Children with Down syndrome: Clinical course and mortality-associated factors in a French medical paediatric intensive care unit.

AIM: To investigate clinical course and mortality-associated factors in children with Down syndrome (DS) managed in a medical paediatric intensive care unit. METHODS: A single-centre, retrospective study conducted between 2001 and 2010 in DS children aged 1 month to 16 years. RESULTS: Sixty-six patients with a median age of 24 months (1-192) and a male/female ratio of 1.5 were analysed. Patients presented with history of congenital heart disease (n = 52, 78.8%), mechanical ventilation (n = 40, 60.6%) and chronic upper airway obstruction (n = 10, 15.1%). The primary reason for admission was respiratory failure (n = 56, 84.8%). Pulmonary arterial hypertension (PAH) (n = 19, 28.8%), acute respiratory distress syndrome (ARDS) (n = 18, 27.2%) and sepsis (n = 14, 21.2%) were observed during their clinical course. Twenty-six patients died (39.4%). Mortality-associated factors included the following: (i) baseline characteristics: history of mechanical ventilation, chronic upper airway obstruction and congenital heart disease; (ii) clinical course during paediatric intensive care unit stay: sepsis, catecholamine support, ARDS, PAH and nosocomial infection. In multivariate logistic analysis, history of mechanical ventilation, ARDS and PAH remained independently associated with death. CONCLUSIONS: The mortality rate in critically ill DS children admitted for medical reasons is high and is predominantly associated with respiratory conditions.

Fatal rhabdomyolysis in 2 children with LPIN1 mutations.

We report 2 cases of fatal rhabdomyolysis in children carrying an LPIN1 mutations preceded by similar electrocardiogram changes, including diffuse symmetrical high-amplitude T waves. Our report underlines the severity of this disease and the need for active management of episodes of rhabdomyolysis in a pediatric intensive care unit.

Robotic lobectomy in children with severe bronchiectasis: A worthwhile new technology.

BACKGROUND/PURPOSE: Lobectomy is required in children affected by non-responsive, symptomatic, localized bronchiectasis, but inflammation makes thoracoscopy challenging. We present the first published series of robotic-assisted pulmonary lobectomy in children with bronchiectasis. METHODS: Retrospective analysis of all consecutive patients who underwent pulmonary lobectomy for severe localized bronchiectasis (2014-2019) via thoracoscopic versus robotic lobectomy. Four 5 mm ports were used for thoracoscopy; a four-arm approach was used for robotic surgery (Da Vinci Surgical Xi System, Intuitive Surgical, California). RESULTS: Eighteen children were operated (robotic resection, n = 7; thoracoscopy, n = 11) with infected congenital pulmonary malformation, primary ciliary dyskinesia, and post-viral infection. There were no conversions to open surgery with robotic surgery, but five with thoracoscopy. Total operative time was significantly longer with robotic versus thoracoscopic surgery (mean 247 ± 50 versus 152 ± 57 min, p = 0.008). There were no significant differences in perioperative complications, length of thoracic drainage, or total length of stay (mean 7 ± 2 versus 8 ± 3 days, respectively). No blood transfusions were required. Two thoracoscopic patients had a type-3 postoperative complication. CONCLUSIONS: Pediatric robotic lung lobectomy is feasible and safe, with excellent visualization and bi-manual hand-wrist dissection - useful properties in difficult cases of infectious pathologies. However, instrumentation dimensions limit use in smaller thoraxes.

Focal seizures with a migrating aspect in infants treated with beta-lactam antibiotics - Report of two cases.

Seizures caused by beta-lactam antibiotics are relatively rare. However, they represent a clinically significant phenomenon and have been widely reported in all age groups. Here we describe two infants presenting subtle multifocal seizures with a migrating aspect on EEG during beta-lactam antibiotic treatment with agents from the carbapenem group (meropenem) and the cephalosporin group (ceftazidime).
