Prevention of neonatal late-onset sepsis: a randomised controlled trial.

BACKGROUND: Late-onset sepsis (LOS), defined as sepsis occurring after 48 h of age causes substantial mortality and morbidity in very low birth weight infants. Risk factors for LOS include immaturity, intravascular catheters, mechanical ventilation, and prolonged parenteral nutrition (PN). Little attention has been paid to studying the effects of PN administration methods. The aim of the study was to compare a bundle of measures for PN line management incorporating a strict aseptic technique with standard line management on LOS in very low birth weight infants. METHODS: Infants <1500 g birth weight who required PN were randomised to either a bundle of a strict aseptic technique for line management together with single use intravascular catheter for PN or a standard technique. The primary outcome was the incidence of LOS in the first 28 days of life. Secondary outcomes were mortality, neonatal morbidities and developmental outcome at 12 months of age. RESULTS: There were 126 infants in the aseptic technique group and 123 in the standard technique group. Forty (31.8%) infants in the aseptic technique group and 36 (29.3%) in the standard technique group had an episode of sepsis (p = 0.77). This corresponds to incidences of 15.8 and 14.2 episodes of sepsis per 1000 patient days respectively. Subgroup analyses for infants <1000 g also revealed no difference in the rate of sepsis between the intervention and control groups. (p = 0.43). There were no significant differences in secondary outcomes and development between the groups. CONCLUSION: A bundle of measures including strict aseptic technique for parenteral nutrition line management did not result in a reduction in LOS when compared to a standard technique. There is no evidence to recommend this as routine practice.

Congenital diaphragmatic hernia in Northern Queensland.

AIMS: To investigate the survival of non-syndromic live born infants diagnosed in Northern Queensland with congenital diaphragmatic hernia (CDH). METHOD: Case note audit was completed of all live born newborns with a diagnosis of CDH admitted between February 1987 and December 2010. Demographic and clinical data were extracted. RESULTS: Overall survival to time of discharge for all infants was 67.3% (n = 35/52). For infants born before 2003 survival was 59.5% and for those born in 2003 and onwards was 86.7% (P = 0.10, OR 4.4, 95% confidence interval (CI) 0.87-22.55). Infants born prior to 2003, compared to those born from 2003 onwards, were less likely to survive with an isolated defect (P = 0.04, OR 8.0, 95% CI 0.93-68.62). Isolated congenital diaphragmatic hernia survival since 2003 was 92.3%. A significant difference was found in the time to surgery with those born in 2003 onwards having surgery significantly later, median 134 h, compared to the earlier cohorts median time to surgery of 83 h (P < 0.005, 95% CI 32.61-167.09). Premature infants had poorer survival (46.7%) compared to term infants (75.7%) (P < 0.0001 OR 3.6, 95% CI 1.99-6.68). Univariate analysis identified low birthweight was associated with poorer survival. CONCLUSIONS: Survival to discharge in our cohort equals other reported rates in Australia and around the world, including centres with tertiary paediatric services. The current management strategies used for these infants have seen a significant improvement in outcomes over time.

Temperature measurement in the preterm and term neonate: a review of the literature.

The maintenance of a constant body temperature is important to all humans but even more so for newborn babies (neonates), especially those born pre-term. Because accurate measurement of body temperature is an important component of thermoregulation management in the neonate, a review of the literature was undertaken to determine the most appropriate method and site of temperature measurement in both the preterm and term neonate. The available evidence indicates that the axilla remains the most common place for temperature measurement.

Application of plastic wrap to improve temperatures in infants born less than 30 weeks gestation: a randomized controlled trial.

PURPOSE: The primary aim of the study was to evaluate whether the application of a plastic wrap immediately after birth is more effective than the standard care of temperature management for improving admission temperatures to the neonatal intensive care unit (NICU) in infants <30 weeks gestation. DESIGN: A randomized controlled trial was conducted. Infants in the intervention group were transferred to a prewarmed radiant heater immediately after birth and encased in NeoWrap from the neck down without being dried. The infant's head was dried with a prewarmed towel and a hat added. The control group received usual care for the unit; the infant was transferred to the prewarmed radiant warmer and dried, and warm towels and a hat are then applied. SAMPLE: A total of 92 infants were analyzed: 49 in the control group and 43 in the intervention group; 48 (52.2 percent) were <27 weeks gestation, and 44 (47.8 percent) were <30 weeks gestation. The infants' temperatures were assessed for two hours following admission.
