Younger age and in situ duration of peripheral intravenous catheters were risk factors for extravasation in a retrospective paediatric study.

AIM: Epidemiological data on the incidence and risk factors of extravasation of peripheral intravenous catheters (PIVC) in neonates and children are scarce and that is what this study explored. METHODS: This was a one-year retrospective study of all neonates and paediatric intensive care patients with at least one recorded PIVC at the Geneva University Hospitals, Switzerland, in 2013. The extravasation rate was determined for all patients, including neonates below 28 days, and for all PIVCs. Multivariate analysis of the associated risk factors was performed. RESULTS: We analysed 1300 PIVC in 695 paediatric patients with a median age of 1.5 years. The overall extravasation incidence was 17.6% for all patients and 11.7% for PIVC. The overall incidence rate of PIVC extravasation was 4.5 per 100 catheters days, and the risk was highest in the 201 neonates, at 28.4%. The incidence rate four days after insertion of the PIVC was around three times higher than on day one. Neonates and the in situ duration of PIVCs were associated risk factors (p < 0.001). CONCLUSION: Extravasation was frequent and neonates were particularly at risk. Younger age and longer in situ PIVC duration were independent risk factors for extravasation.

Retrospective cohort study of all deaths among infants born between 22 and 27 completed weeks of gestation in Switzerland over a 3-year period.

OBJECTIVES: The aim of this research is to assess causes and circumstances of deaths in extremely low gestational age neonates (ELGANs) born in Switzerland over a 3-year period. DESIGN: Population-based, retrospective cohort study. SETTING: All nine level III perinatal centres (neonatal intensive care units (NICUs) and affiliated obstetrical services) in Switzerland. PATIENTS: ELGANs with a gestational age (GA) <28 weeks who died between 1 July 2012 and 30 June 2015. RESULTS: A total of 594 deaths were recorded with 280 (47%) stillbirths and 314 (53%) deaths after live birth. Of the latter, 185 (59%) occurred in the delivery room and 129 (41%) following admission to an NICU. Most liveborn infants dying in the delivery room had a GA ≤24 weeks and died following primary non-intervention. In contrast, NICU deaths occurred following unrestricted life support regardless of GA. End-of-life decision-making and redirection of care were based on medical futility and anticipated poor quality of life in 69% and 28% of patients, respectively. Most infants were extubated before death (87%). CONCLUSIONS: In Switzerland, most deaths among infants born at less than 24 weeks of gestation occurred in the delivery room. In contrast, most deaths of ELGANs with a GA ≥24 weeks were observed following unrestricted provisional intensive care, end-of-life decision-making and redirection of care in the NICU regardless of the degree of immaturity.

The impact of a register on the management of neonatal cooling in Switzerland.

BACKGROUND: Therapeutic hypothermia following hypoxic ischaemic encephalopathy in term infants was introduced into Switzerland in 2005. Initial documentation of perinatal and resuscitation details was poor and neuromonitoring insufficient. In 2011, a National Asphyxia and Cooling Register was introduced. AIMS: To compare management of cooled infants before and after introduction of the register concerning documentation, neuromonitoring, cooling methods and evaluation of temperature variability between cooling methods. STUDY DESIGN: Data of cooled infants before the register was in place (first time period: 2005-2010) and afterwards (second time period: 2011-2012) was collected with a case report form. RESULTS: 150 infants were cooled during the first time period and 97 during the second time period. Most infants were cooled passively or passively with gel packs during both time periods (82% in 2005-2010 vs 70% in 2011-2012), however more infants were cooled actively during the second time period (18% versus 30%). Overall there was a significant reduction in temperature variability (p < 0.001) comparing the two time periods. A significantly higher proportion of temperature measurements within target temperature range (72% versus 77%, p < 0.001), fewer temperature measurements above (24% versus 7%, p < 0.001) and more temperatures below target range (4% versus 16%, p < 0.001) were recorded during the second time period. Neuromonitoring improved after introduction of the cooling register. CONCLUSION: Management of infants with HIE improved since introducing the register. Temperature variability was reduced, more temperature measurements in the target range and fewer temperature measurements above target range were observed. Neuromonitoring has improved, however imaging should be performed more often.

[Neonatal morbidity and mortality in a low-resource urban district hospital of Douala, Cameroon]. / Morbidité et mortalité néonatale dans un hôpital de district urbain à ressources limitées à Douala, Cameroun.

INTRODUCTION: In countries with limited health-care resources, achieving the fourth Millennium Development Goal recommended by the WHO requires the reduction of neonatal mortality. Interventions at different levels of the community and the health-care system are needed, including in district hospitals. METHOD: This was a descriptive study in the neonatal unit of the District Hospital of Bonassama/Douala in Cameroon that analyzed neonatal mortality and morbidity to discover possible intervention levers. The clinical, sociodemographic, and outcome data of hospitalized newborns were recorded from November 2009 to May 2012. The analysis was performed anonymously. RESULTS: During 29 months, 813 infants were hospitalized; 71% were delivered naturally and 16% by cesarean section. Globally, 20% were premature, 55% were male, and 24% had a birth weight of less than 2500 g. At admission, 35% of the infants had hyperthermia and 29% hypothermia. The most common diagnoses were early infection (77%), late infection (22%), jaundice (17%), early adaptation disorders (18%), and hypoxic-ischemic encephalopathy (2.2%). The hospital mortality rate was 8% and the main diagnoses associated with death were: low birth weight, prematurity, hypothermia, and early adaptation disorders with and without encephalopathy. No excess mortality was found for neonates treated for infection. CONCLUSION: In developing sub-Saharan countries, the main causes of neonatal mortality must be taken care of by hospitals at a peripheral district level. Epidemiological knowledge of neonatal diseases at the peripheral level (district) allows for an estimation of the requirements in terms of competence and equipment. Specific needs for transfer to a superior care unit can be estimated but the high transfer risk and the limited resources of the referral center should be taken into account.

[Development and assessment of a sensory-motor scale for the neonate: a clinical tool at the bedside]. / Élaboration et validation de contenu d'une grille d'observation du comportement sensorimoteur du nouveau-né à l'usage du personnel soignant.

INTRODUCTION: Improved perinatal care has increased the survival of newborns. However, neonatal intensive care is a source of nociceptive stimuli that may have a negative long-term impact on the child's neurobehavioral development. During the period of maximal brain plasticity, supportive developmental care can therefore be beneficial. The purpose of this study was to develop an assessment tool of neonatal behavior for daily use by healthcare providers and validate its content. METHOD: A behavioral assessment tool starting off with 45 clinical variables in 6 areas of sensory-motor behavior was validated in two stages using footage of babies between 25 and 37 weeks gestational age. The intraclass correlation coefficient of 65 evaluations allowed simplification of the tool down to 23 variables, prior to a final analysis of validity and reliability. RESULTS: For the 23 variables, the reliability between observers was low for 7 (intraclass correlation coefficient [ICC]<0.4), fair for 4 (ICC 0.4-0.5) and good for 12 (ICC>0.5). The agreement between novice and expert observers ranged from 46.7% to 98.7%. Twenty variables had a level of agreement above 60%. CONCLUSIONS: This validation study of a newborn sensory-motor behavior assessment scale has identified pertinent variables for a structured assessment by healthcare providers.

[Simulation of neonatal resuscitation in the delivery room]. / Simulation de la réanimation en salle de naissance: pratique et développements.

Neonatal resuscitation is one of the most cost-effective medical interventions, most often an emergency procedure involving a multidisciplinary team in the delivery room: doctors, nurses, midwives, obstetricians, anesthetists and other theatre staff. The success of resuscitation depends not only on individual competence but also on efficient teamwork between healthcare professionals in the delivery room; failure often results from the weakest link. Initiation of basic resuscitation procedures must be rapid and effective. Simple procedures must therefore be known by a large number of healthcare professionals, in fact all those potentially present at a delivery. Many complex neonatal diseases on the other hand are too infrequent for all to acquire sufficient personal experience. In addition, synchronization between the interventions of the different members in a perinatal team is complex. It is therefore necessary to train both individuals and teams to better manage perinatal crisis situations. The educational approach should remain multimodal, combining teaching of technical and non-techniques skills. Simulation of resuscitation scenarios can mimic emergency situations without any risk to the patient. It can be used for teaching and/or evaluation of the effectiveness of procedures and collaboration between actors. For maximum performance in complex pathologies, multidisciplinary teaching sessions are necessary. Simulation techniques adapted to neonatal resuscitation in the delivery room appear of great educational interest and proof of their efficiency gradually appears in literature.

Intrapartum Group B streptococcus detection by rapid polymerase chain reaction assay for the prevention of neonatal sepsis.

Group B streptococcus (GBS) is a leading cause of infectious neonatal morbidity and mortality. Timely and accurate identification of colonized mothers is imperative so that antibioprophylaxis can be implemented during labour to reduce the risk of neonatal sepsis. We planned our study to analyse the diagnostic accuracy of an intrapartum PCR assay to identify GBS-colonized women and to allow the implementation of correct (i.e. at least 4 h) intrapartum antibiotic prophylaxis based on the PCR results. We included 695 women in labour who were tested for rectovaginal GBS carriage by culture and PCR. Women were also screened at 35-37 weeks of gestation. Intrapartum GBS colonization was 19.3%. Assay sensitivity was 81.0% for antenatal culture and 85.0% for intrapartum PCR; p 0.72. GBS colonization (n = 107) was known at least 4 h before delivery in 68 (64%) and 73 (68%) women based on antenatal culture and intrapartum PCR, respectively. Among 43 women delivering preterm, correct status was known at least 4 h before delivery in 10 (23%) and 32 (74%) women according to antenatal culture and intrapartum PCR, respectively. These results support the concept that GBS screening can be performed routinely during labour in a clinical setting. The intrapartum approach is at least as accurate as the antenatal screening, with the additional advantage of identifying women delivering preterm or not followed during pregnancy.

[Patient safety indicators for obstetrics: a Delphi based study]. / Indicateurs sécurité en obstétrique : une étude Delphi.

OBJECTIVE: Clinical indicators are increasingly used to assess safety of patient care. In obstetrics, only a few indicators have been validated to date and none is used across specialties. The purpose of this study was to identify and assess for face and content validity a group of safety indicators that could be used by anaesthetists, obstetricians and neonatologists involved in labour and delivery units. MATERIALS AND METHODS: We first conducted a systematic review of the literature to identify potential measures. Indicators were then validated by a panel of 30 experts representing all specialties working in labour and delivery units. We used the Delphi method, an iterative questionnaire-based consensus seeking technique. Experts determined on a 7-point Likert scale (1=most representative/7=less representative) the soundness of each indicator as a measure of safety and their possible association with errors and complications caused by medical management. RESULTS: We identified 44 potential clinical indicators from the literature. Following the Delphi process, 13 indicators were considered as highly representative of safety during obstetrical care (mean score

Noise levels during nCPAP are flow-dependent but not device-dependent.

OBJECTIVE: Nasal continuous positive airway pressure (nCPAP) has been shown to improve the outcome of infants with respiratory distress syndrome. However, noise generation could be of concern. Therefore, our study was designed to measure the noise levels of various CPAP drivers. DESIGN: For infants admitted to our neonatal intensive care unit and paediatric critical care unit, we measured the noise level in the oral cavity, using a microphonic probe with a flexible capillary tube. Various CPAP drivers and interfaces have been tested. RESULTS: 27 measurements were made in eight infants. Mean noise level was 88.6 (SD 18.8) dB and was correlated with flow (p<0.01) but not with pressure. A noise level above 90 dB was detected in 67% of the measurements. CONCLUSIONS: nCPAP drivers are valuable devices for neonatal care that may prevent primary mechanical ventilation or re-intubation, but generate a large amount of noise, often higher than occupational limits accepted for adult workers. Therefore, new devices must be designed to minimise this possible noxious exposure of premature infants to unacceptably high noise levels.

Ex utero intrapartum treatment (EXIT), a resuscitation option for intra-thoracic foetal pathologies.

The ex utero intrapartum treatment (EXIT) procedure is designed to guarantee sufficient oxygenation for a foetus at risk of airway obstruction. This is achieved by improving lung ventilation, usually by establishing an airway during caesarean delivery whilst preserving the foetal-placental circulation temporarily. Indications for the EXIT procedure have extended from its original use in reversing iatrogenic tracheal obstruction in congenital diaphragmatic hernia to naturally occurring upper airway obstructions. We report our experience with a new and rarely mentioned indication for the EXIT procedure, intra-thoracic volume expansions. The elaboration of lowest risk scenarios through balancing risks with alternative options, foetal or neonatal intervention and coordination between professionals from various disciplines are the most important conditions for a successful EXIT procedure. The EXIT procedure requires a caesarean section that specifically differs from the traditional caesarean section during which uterine tone is maintained to minimize maternal bleeding. To guarantee foetal oxygenation during the EXIT procedure, profound uterine relaxation is desired. To gain time with optimal placental oxygenation in order to safely perform an airway intervention in a baby at risk of hypoxia may require deep inhalation anaesthesia and/or tocolytic agents. We review the EXIT procedure and present a case series from the University Hospital of Geneva that contrasts with the common indication for the EXIT procedure usually based on upper airway obstruction by its exclusive indication for intra-thoracic malformations/diseases.

The giant umbilical cord.

The giant umbilical cord is a rare malformation of the umbilical cord that can easily be diagnosed on prenatal scans and is unmistakable postnatally. We report a case to highlight issues of this rare finding. Visual diagnosis is easy and surgical repair is usually required.

Use of a systematic risk analysis method to improve safety in the production of paediatric parenteral nutrition solutions.

BACKGROUND: Until recently, the preparation of paediatric parenteral nutrition formulations in our institution included re-transcription and manual compounding of the mixture. Although no significant clinical problems have occurred, re-engineering of this high risk activity was undertaken to improve its safety. Several changes have been implemented including new prescription software, direct recording on a server, automatic printing of the labels, and creation of a file used to pilot a BAXA MM 12 automatic compounder. The objectives of this study were to compare the risks associated with the old and new processes, to quantify the improved safety with the new process, and to identify the major residual risks. METHODS: A failure modes, effects, and criticality analysis (FMECA) was performed by a multidisciplinary team. A cause-effect diagram was built, the failure modes were defined, and the criticality index (CI) was determined for each of them on the basis of the likelihood of occurrence, the severity of the potential effect, and the detection probability. The CIs for each failure mode were compared for the old and new processes and the risk reduction was quantified. RESULTS: The sum of the CIs of all 18 identified failure modes was 3415 for the old process and 1397 for the new (reduction of 59%). The new process reduced the CIs of the different failure modes by a mean factor of 7. The CI was smaller with the new process for 15 failure modes, unchanged for two, and slightly increased for one. The greatest reduction (by a factor of 36) concerned re-transcription errors, followed by readability problems (by a factor of 30) and chemical cross contamination (by a factor of 10). The most critical steps in the new process were labelling mistakes (CI 315, maximum 810), failure to detect a dosage or product mistake (CI 288), failure to detect a typing error during the prescription (CI 175), and microbial contamination (CI 126). CONCLUSIONS: Modification of the process resulted in a significant risk reduction as shown by risk analysis. Residual failure opportunities were also quantified, allowing additional actions to be taken to reduce the risk of labelling mistakes. This study illustrates the usefulness of prospective risk analysis methods in healthcare processes. More systematic use of risk analysis is needed to guide continuous safety improvement of high risk activities.

"White dots on the placenta and red dots on the baby": congential cutaneous candidiasis--a rare disease of the neonate.

Cutaneous congenital candidiasis (CCC) is a very rare disease of the term or premature infant consisting of a generalized rash at or shortly after birth usually without other signs or symptoms. The presence of white microabscesses on the placenta and umbilical cord of an infant with such a rash must suggest the diagnosis of CCC, which is always secondary to Candida chorioamnionitis but may pass unrecognized. Despite the high prevalence of vulvo-vaginitis in pregnant women, Candida chorioamnionitis is rare and CCC remains apparently extremely rare with just some hundred cases described. However, as the condition is essentially benign and self-limited, underdiagnosis is likely. As occasional systemic spread of Candida infection is described and maternal complications may arise, diagnosis and a close follow-up or treatment is of importance. We present two cases of CCC, stressing the importance of sharing clinical findings between obstetrician and neonatologist for the diagnosis and subsequent management.

Ex utero intrapartum treatment (EXIT) of severe fetal hydrothorax.

Ex utero intrapartum treatment (EXIT) of a fetus with severe bilateral hydrothorax is described. EXIT allows therapeutic interventions on the neonate while maintaining fetoplacental circulation. Thus it may be useful for fetuses presenting with severe pleural effusion towards the end of gestation and in whom in utero drainage is technically not possible or available and drainage post partum would result in profound and prolonged hypoxia until sufficient drainage of pleural fluid allowed lung expansion.

Volume and secretion rate of lung liquid in the final days of gestation and labour in the fetal sheep.

1. Most of the liquid that fills the lung of the fetal sheep in late gestation is cleared by the end of labour. Clearance of this liquid has a beneficial effect on postnatal gas exchange and therefore represents an important adaptation for postnatal life. Despite its importance, there is disagreement about whether clearance begins prior to labour, or occurs entirely within labour. 2. To address this issue, we made serial determinations of lung liquid volume by indicator dilution during late gestation and labour in the fetal sheep. 3. Regression analysis demonstrated that lung liquid volume exhibited a plateau level in the near-term fetus before it began to decline. Two models provided a fit to the decline in volume. In one, lung liquid clearance occurred in two linear phases, the first beginning 70 h before the study was terminated when the ewe was in advanced labour, the second occupying the last 8 h of the study period. In the initial phase, average lung liquid volume fell from 38.3 to 26.4 ml x kg(-1) before a rapid decline in the second phase reduced the volume to 13.8 ml x kg(-1). An exponential decay model was also found to fit the data; this showed a gradual decline in lung liquid volume in the 2 days preceding onset of labour, followed by a much more rapid decline within labour. 4. The rate of lung liquid secretion also declined in two linear phases, both of which commenced earlier than the changes in lung liquid volume. An exponential decay model also gave a significant fit to the data, but the fit was significantly weaker than that achieved with the two-slope model. 5. We conclude that clearance of lung liquid begins well before commencement of labour in the full term fetal sheep, and then accelerates once labour is established. In our study, lung liquid volume fell even in the absence of reabsorption of liquid across the pulmonary epithelium, indicating that outflow of liquid through the trachea must have occurred at a rate in excess of the secretion rate.

Errors in estimating lung liquid volume in fetal lambs when using radiolabeled serum albumin and blue dextran.

Fetal lung liquid volume is usually determined by using radio-iodinated serum albumin (RISA) or blue dextran (BD) as volume tracers. We tested the reliability of both tracers at 124 (G124) and 142 days of gestation (G142; term = G147) when the labels were employed simultaneously. We measured the proportion of label bound reversibly to the lung, or apparently lost from the lung compartment, by washing out the lung with saline and 5% albumin. At G124, volume estimates with the two labels were similar. At G142, the volume estimate with BD (36.3 +/- 8.7 ml/kg of body wt) was higher (P < 0. 05) than with RISA (22.3 +/- 3.5 ml/kg). This difference resulted from reversible binding of BD, because 5% albumin washout released 38.5 +/- 4.0% of the BD added at the start of the experiment but a lesser amount of RISA (9.8 +/- 0.7%; P < 0.05). At G142, when RISA was used alone, its reversible binding was 1.3 +/- 0.2%. Background absorbance increased during experiments, giving rise to an apparent increase in BD concentration. We conclude that RISA is an effective tracer for lung liquid volume determination in the fetal lamb, whereas our findings of substantial epithelial binding of BD and large changes in background absorbance demonstrate that, under the conditions of our experiments, BD is a poor tracer close to term.
