C-reactive protein as a predictor of meningitis in early onset neonatal sepsis: a single unit experience.

Objectives To determine whether there is a cut off value of serum C-reactive protein (CRP) associated with a higher risk of meningitis in suspected early onset sepsis (EOS) (onset birth to 7 days of life). Methods A retrospective cohort study on neonates admitted in neonatal intensive care unit at McMaster Children's Hospital from January 2010 to 2017 and had lumbar puncture (LP) and CRP for workup of EOS. Included subjects had either (a) non-traumatic LP or (b) traumatic LP with cerebral spinal fluid (CSF) polymerase chain reaction or gram stain or culture-positive or had received antimicrobials for 21 days. Excluded were CSF done for metabolic errors, before cytomegalovirus (CMV) treatment; from ventriculo-peritoneal (VP) shunts; missing data and contamination. Neonates were classified into definite and probable meningitis and on the range of CRP. We calculated sensitivity, specificity, and likelihood ratios for CRP values; and area under the receiver operating characteristic (AUROC) curve. Results Out of 609 CSF samples, 184 were eligible (28 cases of definite or probable meningitis and 156 controls). Sensitivity, specificity, predictive values, likelihood ratios, and AUROC were too low to be of clinical significance to predict meningitis in EOS. Conclusions Serum CRP values have poor discriminatory power to distinguish between subjects with and without meningitis, in symptomatic EOS.

Intervention Bundle for Optimization of Procedural Sedation for Newborns Undergoing Magnetic Resonance Imaging: A Single-Center Quality Improvement Project in Qatar.

Introduction: Magnetic resonance imaging (MRI) is a common procedure in tertiary care neonatal intensive care units (NICUs). MRIs aid in detailing structural anatomy and are increasingly utilized for prognostication. Keeping babies calm and motion-free in the MRI suite is challenging, and various approaches have been adopted to obtain the best image quality. We share our experience of intervention bundle for procedural sedation with the novel use of buccal midazolam in our NICU for babies undergoing MRI. Methods: This single-center quality improvement project comprised two epochs. Epoch 1 from April 2018 to December 2020 provided baseline data regarding sedation use and helped identify causes for suboptimal images and the adverse event rate. Following the implementation of an interventional bundle comprising specific midazolam dose recommendations tailored to background risk factors and streamlining the procedural sedation process, similar comparative data were collected in epoch 2 (May 2021 to December 2022) after a washout period. Results: Of 424 patients, 238 and 108 had MRI done under either procedural sedation protocol or feed and wrap technique in epoch 1 and 2, respectively. After excluding babies whose MRIs were performed under sedative infusions, 30 (13%) babies had adverse events in epoch 1, while only 8 (7%) events occurred in epoch 2. There was also a 37% improvement in the documentation of procedural sedation between the two epochs. Conclusion: Procedural sedation with buccal midazolam under neonatologist supervision is safe, efficient, and effective in babies undergoing MRI in this single-center study. More extensive studies may be warranted to assess the suitability of this sedation modality for broader use.

Interventions to Reduce Severe Brain Injury Risk in Preterm Neonates: A Systematic Review and Meta-analysis.

Importance: Interventions to reduce severe brain injury risk are the prime focus in neonatal clinical trials. Objective: To evaluate multiple perinatal interventions across clinical settings for reducing the risk of severe intraventricular hemorrhage (sIVH) and cystic periventricular leukomalacia (cPVL) in preterm neonates. Data Sources: MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases were searched from inception until September 8, 2022, using prespecified search terms and no language restrictions. Study Selection: Randomized clinical trials (RCTs) that evaluated perinatal interventions, chosen a priori, and reported 1 or more outcomes (sIVH, cPVL, and severe brain injury) were included. Data Extraction and Synthesis: Two co-authors independently extracted the data, assessed the quality of the trials, and evaluated the certainty of the evidence using the Cochrane GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach. Fixed-effects pairwise meta-analysis was used for data synthesis. Main Outcomes and Measures: The 3 prespecified outcomes were sIVH, cPVL, and severe brain injury. Results: A total of 221 RCTs that assessed 44 perinatal interventions (6 antenatal, 6 delivery room, and 32 neonatal) were included. Meta-analysis showed with moderate certainty that antenatal corticosteroids were associated with small reduction in sIVH risk (risk ratio [RR], 0.54 [95% CI, 0.35-0.82]; absolute risk difference [ARD], -1% [95% CI, -2% to 0%]; number needed to treat [NNT], 80 [95% CI, 48-232]), whereas indomethacin prophylaxis was associated with moderate reduction in sIVH risk (RR, 0.64 [95% CI, 0.52-0.79]; ARD, -5% [95% CI, -8% to -3%]; NNT, 20 [95% CI, 13-39]). Similarly, the meta-analysis showed with low certainty that volume-targeted ventilation was associated with large reduction in risk of sIVH (RR, 0.51 [95% CI, 0.36-0.72]; ARD, -9% [95% CI, -13% to -5%]; NNT, 11 [95% CI, 7-23]). Additionally, early erythropoiesis-stimulating agents (RR, 0.68 [95% CI, 0.57-0.83]; ARD, -3% [95% CI, -4% to -1%]; NNT, 34 [95% CI, 22-67]) and prophylactic ethamsylate (RR, 0.68 [95% CI, 0.48-0.97]; ARD, -4% [95% CI, -7% to 0%]; NNT, 26 [95% CI, 13-372]) were associated with moderate reduction in sIVH risk (low certainty). The meta-analysis also showed with low certainty that compared with delayed cord clamping, umbilical cord milking was associated with a moderate increase in sIVH risk (RR, 1.82 [95% CI, 1.03-3.21]; ARD, 3% [95% CI, 0%-6%]; NNT, -30 [95% CI, -368 to -16]). Conclusions and Relevance: Results of this study suggest that a few interventions, including antenatal corticosteroids and indomethacin prophylaxis, were associated with reduction in sIVH risk (moderate certainty), and volume-targeted ventilation, early erythropoiesis-stimulating agents, and prophylactic ethamsylate were associated with reduction in sIVH risk (low certainty) in preterm neonates. However, clinicians should carefully consider all of the critical factors that may affect applicability in these interventions, including certainty of the evidence, before applying them to clinical practice.

Hypernatremia in Newborns: A Practical Approach to Management.

Hypernatremia is a potentially serious condition in both term and preterm babies, which can lead to severe and permanent neurological damage. There are many physiological changes in sodium homeostasis that occur soon after birth. Understanding this physiological process, early anticipation of hypernatremia and familiarization with the neonatal management of hypernatremia can prevent mortality and long-term morbidity associated with this condition. This review aims to provide a practical and understandable approach to the diagnosis and management of hypernatremia in neonates.

Amplitude-Integrated Electroencephalography: A Primer for Neonatologists and Practitioners in the NICU.

Amplitude-integrated electroencephalography (aEEG) is an essential tool used in the NICU to monitor infants with central nervous system pathology and encephalopathy. This review provides a summary of aEEG, including clinical indications, interpretation of different tracing patterns, and seizure identification, which are essential skills for teams caring for sick newborns. We also discuss the limitations of the clinical application of aEEG in this population.

Quality of Neonatal Care: A Health Facility Assessment in Balochistan Province, Pakistan.

Introduction Balochistan is the largest of Pakistan's four provinces, yet it is also the poorest and most impoverished, particularly in terms of neonatal healthcare. In order to build and tailor strategies to improve neonatal outcomes, it is necessary to identify barriers and facilitators for interventions. Therefore, we conducted this study to provide an overview of neonatal healthcare quality and assess the structural capacity for the improvement and further development of neonatal healthcare facilities in Balochistan. Methods A descriptive, observational, cross-sectional study was conducted in Balochistan, a province of Pakistan. The survey was designed to assess the level of staffing and facilities in the neonatal health care units. Data were gathered through trained staff either by in-person visits to the facility or via telephone. Results A total of 177 facilities were assessed in 25 districts of Balochistan. A majority (88.7%) of the facilities were from the public sector. Birth and neonatal care services were provided at only 63 (36%) of the assessed facilities and only three had newborn intensive care units (NICUs) with a 1:5 staff: patient ratio. Unfortunately, all NICUs lacked the basic advanced facilities. None of the hospitals had an infection control policy or staff nor any training program for doctors. Conclusion In conclusion, healthcare facilities to manage neonatal patients requiring hospital care are extremely limited in Balochistan and the ones that are available have very limited resources. To improve the healthcare system in Balochistan, all stakeholders should be involved in the planning, decision-making, and implementation of healthcare programs at all levels to ensure sustainability and efficiency.

Effect of Optimizing Oxygen Saturation Targets on the Incidence of Retinopathy of Prematurity in a Quaternary NICU.

Introduction: Retinopathy of prematurity (ROP) is a multifactorial disease and a preventable cause of blindness in childhood. Hyperoxia and hypoxia can cause retinal neovascularization resulting in retinal detachment and blindness if left untreated. Besides oxygen treatment, other reasons for ROP development are well known. We prospectively adopt various strategies to keep oxygen saturation (SpO2) within targets, between 91 and 95% for those on supplemental oxygen. By adapting this, we postulated that the incidence of severe ROP might be reduced. Methods: 2018-2019 provided pre-intervention and 2020 post-intervention data for the project. For all babies (≤32 weeks, ≤1,500 g with FiO2 >0.21), target SpO2 between 91 and 95% was measured as a percentage of time spent within and outside target SpO2 during 1-4 weeks of life. Results: 112 and 60 preterm neonates were screened for ROP during the pre- and post-intervention phase. Twenty neonates (18.3%) during pre-intervention and 16 (26.7%) in the post-intervention phase developed severe ROP requiring treatment. Despite a statistically significant increase of 10 percent points in time spent within target SpO2 (91-95%) in the post-intervention phase (p < 0.05), the incidence of severe ROP did not decline. Using a multivariate model, odds of ROP development decreased with gestational age (25%) while increasing with PDA requiring treatment (4.33 times) and glucose ≥10 mg/dL (4.15 times), considering one variable at a time, keeping others constant. Conclusion: Our QI project showed successful attainment of maximum time; the SpO2 remained within targets during supplemental oxygen; however, the incidence of severe ROP had not declined. Factors other than SpO2 might be responsible for a high incidence of ROP in our neonatal intensive care unit.

Association of Low Umbilical Cord pH and Hypoglycemia in Healthy Term Newborns: Should it Be a Part of Postnatal Screening?

Hypoglycemia may lead to neurological impairment; therefore, high-risk newborns are screened postnatally. However, hypoglycemia monitoring protocols often do not include cord blood acidosis as a risk factor. The study aimed to find an association between asymptomatic cord blood acidosis and hypoglycemia. All healthy term infants born at McMaster Children Hospital, Hamilton, Canada, between October 2013 and September 2014, who had umbilical cord blood pH <7.0 or base excess <12 mmol/L were studied. Infants with evidence of hypoxic-ischemic encephalopathy, birth weights outside of 10th to 95th percentiles for gestation, mothers with preeclampsia, diabetes or taking a -blockers at the time of the birth were excluded. Hypoglycemia was defined as blood glucose <2.6 mmol/L in the first two hours of life. One hundred sixtysix infants met the cord blood gas criteria, but only 16 had hypoglycemia. Although infants with mild perinatal depression are at risk for hypoglycemia, a significant association could not be proved.

Bone marrow examination in ITP in children: is it mandatory ?

OBJECTIVE: To determine the need of bone marrow examination in children with idiopathic thrombocytopenic purpura (ITP) at initial presentation. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF THE STUDY: Pediatric Units of Children Hospital, Islamabad, from January 1999 to December 2003. PATIENTS AND METHODS: All children, clinically suspected to have ITP, who underwent bone marrow examination, were included After reviewing the file records of these patients for history, examination and investigations, a predesigned proforma was filled and data was analyzed, using SPSS version 10 for statistical analysis. The results were reported in the form of frequencies, percentages and mean. RESULTS: A majority of the children were between 48 to 96 months, with a mean age of 54.43 months. Male to female ratio was 1.45:1. Mean platelet count was 33861/mm(3). None of the bone marrow results showed the presence of abnormal cells consistent with hematological malignancy. ITP was the final diagnosis in 52 patients. One patient was diagnosed to have megakaryocytic hypoplasia. Bone marrow aspiration in one patient was hypoplastic, and subsequently, he was diagnosed to have aplastic anemia on trephine biopsy. CONCLUSION: Bone marrow aspiration should not be a part of routine work-up for diagnosing ITP in children and should be reserved for those children having atypical clinical and laboratory features.

Neurally adjusted ventilatory assist mode used in congenital diaphragmatic hernia.

A term baby with congenital diaphragmatic hernia (CDH) underwent surgical repair on the second day of life. Postoperatively; the oxygenation index increased to 85 despite high pressure ventilation with HFOV (high frequency oscillator ventilation) and inhaled nitric oxide therapy. Oxygenation index above 70 carries a mortality rate of 94% and merits starting extracorporeal membrane oxygenation (not available in the UAE). A trial of neurally adjusted ventilatory assist (NAVA) on the 10th postoperative day was followed by a reduction of oxygenation index to 15 and marked improvement of the clinical parameters. The EAdi (electrical activity of diaphragm) signal was relatively weak (± 5 µvolt) requiring augmentation with a high NAVA level (3 - 3.5). The patient was successfully extubated after 3 weeks.
