RESUMO

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.

RESUMO

INTRODUCTION: Nonsynostotic posterior plagiocephaly has become the most common skull deformation since pediatricians have suggested the supine position for the newborns to reduce the risk of sudden death. Prevention of such a "positional" deformation or its management once it has occurred is mainly based on physical maneuvers such as physiotherapy and active positional corrective measures. SELECTION CRITERIA: Surgical correction, however, may be suggested in rare cases where deformation of the skull is so severe or the referral of the child is so late that physical corrective treatment cannot be taken into consideration. Surgical management is based on the creation of a posterior bone flap to be repositioned after the opportune contouring and rotation. PURPOSE: The aim of this paper is to describe the surgical technique used for posterior vault remodeling in posterior plagiocephaly at the craniofacial unit of Hopital Necker Enfants Malades (French National Referral Center for Faciocraniosynostosis) focusing on its advantages and limitations.

RESUMO

OBJECTIVE: To report daily practice of scene emergency tracheal intubation performed by physicians and changes induced by implementation of national guidelines, with special attention to rapid sequence induction (RSI) and control of assisted ventilation. DESIGN: Observational study. SETTING: Pediatric intensive care unit of a university hospital. PATIENTS: A total of 296 children (age, 2-15 yrs old) referred to our center for severe traumatic brain injury (Glasgow Coma Scale score of ≤ 8), with spontaneous cardiac rhythm. INTERVENTIONS: Scene RSI practice by field physicians was compared before (n = 188), and after (n = 108) publication of national guidelines. Emergency tracheal intubation conditions, RSI use, immediate complications, assisted ventilation efficiency on blood gases measurements upon arrival, and, in the later period, physician's knowledge, and observance to published guidelines were analyzed. MEASUREMENTS AND MAIN RESULTS: After publication of guidelines, tracheal intubation was performed at the scene in 100% of the cases (vs. 88%, p = .05); RSI practice was more standardized, with an increased use of succinylcholine (10% to 80%, p = .0001), and a concomitant decreased use of nondepolarizing muscle relaxant (20% vs. 0%, p = .005), and opioids (70% vs. 36%, p = .05). Recommended RSI protocol (etomidate and succinylcholine) was effectively used by 64% of the physicians (vs. 2.8%, p = .001), and rate of immediate complications upon tube insertion (mainly cough reflex) decreased to 8% (vs. 25%, p = .0015). Scene emergency tracheal intubation, when ordered, resulted in a 100% success rate and adequate oxygenation within the two groups. Despite increasing the use of portable capnograph in the later period, Paco2 was measured outside the tight target range (35-40 torr, 4.6-5.3 kPa) in 70% of the cases upon arrival. CONCLUSIONS: Scene emergency tracheal intubation was effectively performed by trained careproviders in children with traumatic brain injury. Implementation of guidelines led to a more standardized practice of RSI, decreased rate of immediate complications, but insufficient control of Paco2 during transport.

RESUMO

BACKGROUND: Traumatic brain injury is a public health problem around the world, and recognition of systemic sources of secondary brain lesions is crucial to improve outcome. OBJECTIVE: To identify the main predictors of mortality and to propose a grading scale to measure the risk of death. METHODS: This retrospective study was based on medical records of children with severe traumatic brain injury who were hospitalized at a level I pediatric trauma center between January 2000 and December 2005. Multiple logistic regression analysis was done to identify independent factors related to mortality. A receiver-operating characteristics curve was performed to verify the accuracy of the multiple logistic regression, and associations that increased mortality were verified. RESULTS: We identified 315 children with severe head injury. Median Glasgow Coma Scale score was 6, and median Pediatric Trauma Score was 4. Global mortality rate was 30%, and deaths occurred despite adequate medical management within the first 48 hours in 79% of the patients. Age < 2 years (P = .02), Glasgow Coma Scale ≤ 5 (P < 10), accidental hypothermia (P = .0002), hyperglycemia (P = .0003), and coagulation disorders (P = .02) were all independent factors predicting mortality. A prognostic scale ranging from 0 to 6 that included these independent factors was then calculated for each patient and resulted in mortality rates ranging from 1% with a score of 6 to 100% with a score of 0. CONCLUSION: Independent and modifiable mortality predictors could be identified and used for a new grading scale correlated with the risk of mortality in pediatric traumatic brain injury.

RESUMO

BACKGROUND: The correct size of cuffed endotracheal tube (CET) limits the risk of postintubation tracheal damage. The aim of this study was to compare the size of the CET used in children with the size predicted by the Khine formula [age (years)/4 + 3]. METHODS: After ethical committee approval, 204 children aged 1 day-15 years were included prospectively in the study. The choice of the size of the CET was made at the discretion of the attending anesthesiologist. The main criterion of judgment was the comparison of the leak before and after inflating the cuff at a pressure of 20 cm.H(2)O. Demographic data, tracheal tube size used and that predicted by Khine's formulae and side-effects were recorded. RESULTS: Overall, 21% of the CET were in accordance with the size predicted by the Khine formula. In the remaining patients, 72% were oversized and 7% undersized. In 12 cases, the size of CET chosen initially was modified: for a larger size in eight children and for a smaller size in four others. Six children (2.9%) presented with minor postoperative complications. CONCLUSIONS: Our data suggest that Khine's formula for predicting the appropriate tracheal tube size underestimates optimal size by 0.5 mm. We therefore recommend the use of the following formula: internal diameter of the CET = [age/4 + 3.5] in children >1 year of age which may be applied without increased risk of complications. The rate of tracheal reintubation as well as the detected leaks supports these recommendations.

RESUMO

Our aim was to determine how isoflurane modified crossbridge (CB) number and kinetics in airway smooth muscle (ASM) and to compare its effects in Fisher and Lewis rats, two strains with differences in airway responsiveness. The effects of isoflurane (2 MAC) on isotonic and isometric contractility in tracheal ASM strips were investigated after methacholine (10(-6) M)-induced contraction. CB mechanics and kinetics were analyzed using the formalism of Huxley's equations adapted to ASM. After isoflurane, maximum velocity did not differ from baseline in Lewis rats, whereas it was significantly less than baseline in Fisher rats ( approximately 25%), the most reactive strain. Isoflurane totally reversed methacholine-induced increase in active CB number in Lewis rats (2.4 +/- 0.5 versus 1.8 +/- 0.4 10(9)/mm(2) after methacholine and isoflurane, respectively) whereas reversal was only partial in Fisher rats (2.7 +/- 0.4 versus 2.1 +/- 0.3 10(9)/mm(2) after methacholine and isoflurane, respectively). Isoflurane induced a 40% increase in attachment step duration in both strains and an almost twofold increase in the CB cycle duration compared with baseline in Lewis rats. The isoflurane-induced increase in detachment step duration was less in Lewis than in Fisher rats (P < 0.05). We concluded that isoflurane modulated CB number and CB cycling rates of isolated rat ASM differently depending on the level of airway responsiveness.
