Singapore Neonatal Resuscitation Guidelines 2016.

We present the revised Neonatal Resuscitation Guidelines for Singapore. The 2015 International Liaison Committee on Resuscitation Neonatal Task Force's consensus on science and treatment recommendations (2015), and guidelines from the American Heart Association and European Resuscitation Council were debated and discussed. The final recommendations of the National Resuscitation Council, Singapore, were derived after the task force had carefully reviewed the current available evidence in the literature and addressed their relevance to local clinical practice.

Reducing radiation hazard opportunities in neonatal unit: quality improvement in radiation safety practices.

AIM: Guided by the ALARA - "As Low As Reasonably Achievable" principle in radiation safety, a quality improvement project to optimise the bedside diagnostic imaging process to the best standards of care was conducted over a six month period. The goal was too reduce the radiation hazard opportunities in the neonatal intensive care unit by at least 75% from the existing level at Q2/2015, within 6 months. METHODS: The existing bedside imaging process was critically analysed and the following quality improvement initiatives were implemented namely, mandatory lead protective gear to healthcare staff, gonadal shield for neonates, guidelines for optimal collimation of X-ray beam and optimal positioning of neonates. Radiation dosimetry results, regular staff awareness sessions and strong collaboration between neonatologists, radiologists, radiographers and neonatal nurses helped to ensure compliance to the revised imaging process. Radiation hazard opportunities were measured by analysing all radiographs done during the period under baby exposure and healthcare staff exposure categories. SUMMARY OF RESULTS: Radiation hazard opportunities were reduced by 100% to healthcare staff and 75% to neonates, and the overall reduction was 83%. The rate of discordance between radiograph request forms and images taken was measured as a surrogate marker for compliance to the project initiatives and it declined by 77%. Mandatory orientation of staff to the revised policy on the standardised diagnostic imaging process, regular radiation awareness talks and staff feedback sessions are among several measures taken to sustain the project.

Children with developmental and behavioural concerns in Singapore.

INTRODUCTION: Childhood developmental and behavioural disorders (CDABD) have been increasingly recognised in recent years. This study evaluated the profiles and outcomes of children referred for developmental and behavioural concerns to a tertiary child developmental centre in Singapore. This is the first such regional database. METHODS: Baseline information, obtained through a questionnaire, together with history at first consultation, provided information for referral, demographic and presentation profiles. Clinical formulations were then made. Definitive developmental and medical diagnoses, as well as outcomes based on clinical assessment and standardised testing, were recorded at one year post first consultation. RESULTS: Out of 1,304 referrals between January 1, 2003 and December 1, 2004, 45% were 2-4 years old and 74% were boys. The waiting time from referral to first consultation exceeded four months in 52% of children. Following clinical evaluation, 7% were found to be developmentally appropriate. The single most common presenting concern was speech and language (S&L) delay (29%). The most common clinical developmental diagnosis was autism spectrum disorder (ASD) (30%), followed by isolated S&L disorder, global developmental delay (GDD) and cognitive impairment (CI). Recommendations included S&L therapy (57%), occupational therapy (50%) and psychological/behavioural services (40%). At one year, ASD remained the most common definitive developmental diagnosis (31%), followed by S&L disorder, CI and GDD. Most were children with high-prevalence, low-moderate severity disorders who could potentially achieve fair-good prognosis with early intervention. CONCLUSION: Better appreciation of the profile and outcome of children with CDABD in Singapore could enable better resource planning for diagnosis and intervention.

Maintaining optimal oxygen saturation in premature infants.

INTRODUCTION: Advances in technology have resulted in increasing survival rates for premature infants. Oxygen therapy is commonly used in neonatal units as part of respiratory support. The number of premature infants in our institution surviving with severe (stage ≥3) retinopathy of prematurity (ROP) prompted a review of oxygen therapy as a contributing factor. Prolonged exposure to high concentrations of oxygen may cause irreversible damage to the eyes of very-low-birth-weight preterm infants and is a potential cause of blindness. OBJECTIVE: We developed strategies to reduce incidence of severe ROP requiring laser surgery in premature infants. METHODS: We studied 37 preterm infants who were born at a gestational age of <32 weeks, with a birth weight of <1500 g, receiving supplemental oxygen, and had been admitted to our neonatal intensive care unit. Infants received oxygen via mechanical ventilator, nasal continuous positive airway pressure (CPAP), or intranasal (I/N) and titration of oxygen was based on each infant's measured oxygen saturation (Spo(2)). For each infant, we monitored the Spo(2) trend, Spo(2) alarm limit, and the percentage of time that the alarm limit was set incorrectly. We implemented a Spo(2) targeting protocol and developed an algorithm for titrating fraction of inspired oxygen (Fio(2)). RESULTS: After phase 1 of implementation, the percentage of time that Spo(2) readings were >95% was reduced to between 20% and 50%. However, our findings raised concern regarding the wide fluctuation of Spo(2) readings because of inconsistency in Fio(2) titration, which can contribute to deviation from the optimal target range. Accordingly, we developed an algorithm for titrating Fio(2) aimed at maintaining each infant's Spo(2) within the optimal target range. After phase 2 of implementation, the percentage of Spo(2) readings >95% was markedly reduced to between 0% and 15%. The incidence of infants with severe ROP requiring laser surgery decreased from 5 to 1. CONCLUSIONS: A change in clinical practice aimed at maintaining oxygen within the target range to avoid a high Spo(2) was associated with a significant decrease in the incidence of both severe ROP and the need for laser surgery, thus reducing hospital costs and length of hospital stays for premature infants.

Identifying risk of neonatal hyperbilirubinaemia and early discharge for glucose-6-phosphate dehydrogenase deficient newborns in Singapore.

INTRODUCTION: This study aims to compare and assess usefulness of day 3 and 4 (49 to 96 hours) pre-phototherapy total serum bilirubin (TSB) in predicting subsequent significant hyperbilirubinaemia (SHB) in glucose-6-phosphate dehydrogenase (G6PD) deficient neonates. MATERIALS AND METHODS: This prospective study was on all the G6PD deficient newborns weighing >2500 g. Day 3 and 4 pre-phototherapy TSB and phototherapy requirements in their first 2 weeks of life were analysed for its value in predicting subsequent SHB. RESULTS: The frequency of G6PD deficiency was 2.4%, 1 per 42 live births (1.3% in males and 1.1% in females). Phototherapy was required in 51% of G6PD deficient infants, all within the first week of life. In the absence of SHB in the first week, the probability of its development in the second week was zero (95% confidence interval, 0 to 0.051). The day 4 pre-phototherapy TSB of <160 micromol/L predicted no measurable risk of subsequent SHB (sensitivity, 94%; 95% confidence interval, 83.5% to 97.9%; specificity 82.8%; 95% confidence interval, 71.1% to 90.4%). CONCLUSIONS: G6PD deficient newborns without SHB in their first week of life were at no measurable risk of its development in the second week. Day 4 pre-phototherapy has better sensitivity and specificity compared to day 3 pre-phototherapy TSB in predicting the risk of subsequent SHB. Low-risk infants, thus identified, may be eligible for discharge on or before day 7 of life. Infants with Day 4 TSB <160 can be even discharge on day 4 with follow-up appointment. Evidence-based early discharge can decrease the social, emotional and financial burden of G6PD deficiency in Singapore.
