Smooth Roads Ahead: Lessons From our Sick Neonate Retrieval Service.

Strategies for free transfer of sick neonates to hospitals are in place, but reports suggest suboptimal status of the same across the country. Over 7 years, our Sick Neonate Retrieval Service (SNRS) transported 165 neonates, of whom 92.1% survived. Safe, stable transportation mandates the presence of a neonatology-trained doctor and nurse in an equipped ambulance.

Cardiorespiratory Adverse Events after First Vaccination in Preterm Neonates With Gestational Age ≤30 Weeks.

OBJECTIVE: To document the adverse cardiorespiratory events following first routine immunization in preterm neonates. METHODS: We retrieved records of neonates with gestational age ≤30 weeks, and included those who developed cardiorespiratory events after first vaccines before discharge. Our Unit's protocol is to administer Bacillus Calmette-Guerin (BCG), hepatitis B vaccine to those discharged at <8 weeks postnatal age. Hexavalent, BCG, pneumococcal vaccine and rotavirus vaccines are given at 8 weeks of age, if hospital stay is predicted to be longer. Unit compliance to vaccination administration at appropriate ages were also measured. RESULTS: Data of 161 neonates ≤30 weeks (17.4% <27 week) who completed care in the unit was studied. Cardio-respiratory adverse events were reported in 21(13.7%). None of these required initiation of invasive ventilation. High flow nasal cannula therapy and caffeine restart were required for these events in 14 (9.3%) and 6 (3.9%) neonates, respectively. Lower gestational age, bronchopulmonary dysplasia and sepsis were significant risk factors on univariate analysis. On multivariate analysis, continued need for respiratory support at 4 weeks of age (P=aOR 14.5 (95% CI 5-59.1) was the only independent risk factor for post-vaccination cardiorespiratory adverse events. Of 38 who were not vaccinated at recommended ages by unit policy, 25 were missed opportunities, the rest were deemed unstable for vaccinations at that age by the clinical team. CONCLUSION: Adverse cardiorespiratory events were uncommon after first vaccinations in very preterm neonates. Administering vaccines in this group before discharge would allow monitoring for these events, especially for those who require long-term respiratory support.

Effect of Clinician-directed Technical Specifications on Entrance Skin Doses in Neonates.

OBJECTIVE: To compare the entrance skin doses (ESD) before and after implementation of a radiation safety policy in neonates (RSN), which focused on clinician-directed technical specifications on the digital X-ray machine. METHODS: Prospective observations included two sets of X-rays: Before (BRSN) and after (ARSN) implementation of RSN (documented indication for X-ray/expected posttest findings, settings of 40 kVp, 0.5 mAs, film-focus distance 100 cm, gonadal-shield, optimal collimation, and post-shoot image-enhancement). RESULTS: 33 and 32 X-rays were analyzed in respective groups. Mean (SD) of calculated and machine-quantified ESD (µGy/m2) was higher in BRSN group as compared to ARSN group (P <0.001). All ARSN X-rays were interpretable for expected post-test findings. CONCLUSION: Clinicians' cognizance of ability to make consequential bedside technical specifications, can reduce ESD without affecting interpretability. These single observations could have a larger impact in sick neonates, where multiple X-rays are done.

Optimizing antibiotic use in culture-negative healthcare-associated infection with a 'stop' policy: a descriptive analytical study.

BACKGROUND AND OBJECTIVES: Many sick neonates receive antibiotics for the clinical diagnosis of probable/possible sepsis. Reports suggest rampant antibiotic use in culture-negative sepsis. We introduced an antibiotic stop policy (ASP), by defining 'completed course duration of antibiotics' in the setting of culture-negative suspected healthcare-associated infection (HAI). Antibiotic overuse days (AOD) before antibiotic stop policy (BASP) and after antibiotic stop policy (AASP) were compared. METHODS: This descriptive analytical study was conducted to measure the change in AOD after implementing ASP in culture-negative HAI. We also sought to evaluate situations in which antibiotic overuse is likely (lower gestation, ventilation, central lines) and safety of the ASP, measured as not having to restart antibiotics in the week following completed course. RESULTS: A total of 126 neonates were initiated on a new antibiotic (started or changed) for suspected HAI. Of these, 43 were excluded. Patient days of 5175 and 5208 were analyzed in BASP and AASP, respectively. Implementation of an ASP reduced AOD (from 14.49 to 3.26 AOD per 1000 patient days; p value <0.01). Safety was ensured; the number of babies who had to be restarted on antibiotics within 1 week of stopping therapy was similar in both groups. All-cause mortality and relevant morbidities were comparable between groups. CONCLUSIONS: A significant decrease in AOD after the introduction of an ASP was noted, in neonates with culture-negative suspected HAI. This difference was noted even in the most vulnerable extreme preterm babies and those requiring ventilation and central lines.

Prevalence of Group B Streptococcus in pregnant women in Kerala and relation to neonatal outcomes: a prospective cross-sectional study.

BACKGROUND AND OBJECTIVES: Early onset sepsis (EOS) in neonates is a scourge that contributes to morbidity and mortality. Prominent stakeholders recommend universal screening of antenatal women for Group B Streptococcus (GBS) and intrapartum antibiotic prophylaxis (IAP) for those who are carriers. However, there are controversies. Other guidelines allow region-specific protocols due to sociodemographic, geographical and ethnic differences. We planned to analyze the prevalence of GBS rectovaginal carriage at 36-37 weeks gestation and its effect on early neonatal status. METHODS: This prospective multidisciplinary study (Obstetrics, Perinatology, Neonatology, Microbiology and Infectious diseases) was conducted in our tertiary care center between February 2020 and May 2021. RESULTS: In our study group which included 966 mothers who delivered at the hospital, 4.8% of mothers who were screened by genito-rectal swabs were positive for GBS at 36-37 weeks gestation. All these mothers were given IAP as per protocol. Other organisms detected on screening mothers were Candida and Gram-negative bacteria. None of the neonates born to these mothers required any intensive care unit admission or therapy for systemic illness. There was no difference in clinically relevant outcomes between neonates who were born to GBS-positive mothers as compared to those born to negative screen result mothers. CONCLUSIONS: GBS prevalence in our cohort was lower than most scientific reports. The neonates born to carrier mothers did not present with signs of early-onset sepsis.

Every treasured drop! Blood transfusion requirements in very preterm neonates after implementation of blood conservation strategies: an observational analytical study.

BACKGROUND: Certain morbidities are inevitable in preterm infants; the challenge lies in minimizing them. Anemia of prematurity is multifactorial. Therapy largely depends on adult red blood cell transfusions (RBCT); which inherently, are not without problems. Most literature in this respect are retrospective or evaluate individual stratagems to reduce RBCT. METHODS: This observational analytical study was planned to compare need for RBCT, before and after institution of blood conservation strategies (BCS). All those ≤30 weeks gestation at birth during two-time epochs were included (Before BCS: retrospective; After BCS: prospective). BCS constituted of delayed cord clamping (DCC), strict sampling indications, micro-sampling with point-of-care testing (MS-POCT) and adherence to RBCT thresholds. RESULTS: Of 45 enrolled neonates in each group, proportion of those requiring even 1 RBCT was significantly reduced after BCS [51.1% vs. 26.7%, p = 0.02, OR 0.35, 95%CI (0.14, 0.84)]. Calculated cumulative blood volume losses (35.3 ml vs. 21.9 ml) and loss per kilogram birth weight (35.3 ml/kg vs. 20.12 ml/kg) were significantly lower after BCS (p = 0.0036). Need for >1 RBCT, mean lowest Hb, mean maximum-hemoglobin drop, need for arterial lines were reduced. Adherence to RBCT thresholds were acceptably good in both time epochs. However, the compliance to DCC was low in both groups, identifying one area of focus with scope for massive improvement. CONCLUSIONS: Need for RBCT transfusions largely attributable to reduced blood losses for lab analysis were reduced after BCS. Installation of in-house MS-POCT seemed to be the pivotal factor. Units that care for very preterm infants must make attempts to procure MS-POCT equipment.

• Institution of a conglomerate of blood conservation strategies (BCS) is an effective strategy to reduce red blood cell transfusion requirements in very preterm infants. • The need for multiple transfusions, calculated cumulative blood volume losses, number of venous samples drawn are also reduced with BCS. • The most important component of BCS is the availability of micro-sampling-point-of-care-testing technology. This facility will benefit centers which care for these high-risk infants.

Incidence of Metabolic Bone Disease After Implementation of Bone Protective Nutritional Strategies: A Prospective Cohort Study.

BACKGROUND: Metabolic bone disease (MBD) is a morbidity of multifactorial etiology with a high incidence in very preterm infants. We planned to study the incidence of MBD after implementation of bone health focussed nutritional strategy (BNS) in those <30 weeks gestation at birth. METHODS: This prospective cohort study including preterm newborns (<30 weeks) who received nutrition that incorporated (a) Early initiation of intravenous potassium phosphate; (b) Early enteral supplementation with multicomponent human milk fortifier at enteral feed tolerance of 40 mL/kg/day feeds itself; and (c) Weekly phosphorus measurements with optimization of enteral intakes. Incidence of MBD at 4 weeks of postnatal age and beyond were analyzed. Other relevant safety and clinical outcomes were measured. RESULTS: Of the 67 included neonates receiving BNS, 20.9% were classified as MBD. There was a low rate of hyper-phosphatemia (4.5%) and hyperkalemia (2.9%). Full enteral feeds were achieved by median (IQR) of 6 (5,7) postnatal days. CONCLUSION: In preterm newborns (24-30 weeks) MBD incidence was 20.9% after BNS was implemented. Intravenous potassium salt of phosphorus and early use of HMF were safe and feasible.

Microvillus Inclusion Disease: A Rare Mutation of STX3 in Exon 9 Causing Fatal Congenital Diarrheal Disease.

Inherited diarrheal disorders cause serious morbidity resulting in dependence on intensive care and parenteral nutrition. Microvillus inclusion disease (MVID) has been classically described and results from mutations in the gene coding myosin Vb, which is responsible for enterocyte polarization. Newer reports of mutations resulting in truncated syntaxin 3 (STX3) and Munc18-2 (STXBP2) proteins have been elucidated as causative. To date, five cases of STX3 abnormalities resulting in MVID have been described. We report an infant who presented with congenital diarrhea and was determined to have a rare mutation of STX3. This new finding would be beneficial in future functional genotype-phenotype correlation studies.

Endotracheal Aspirate and Ventilator-Associated Pneumonia in Neonates: Revisiting an Age-Old Debate.

OBJECTIVES: To explore the utility of endotracheal aspirates (ETA) for analyzing microbiological yield, incidence, risk factors for VAP, and clinically relevant outcomes. METHODS: Ventilated neonates suspected to have VAP were studied prospectively; they were classified as "VAP" or "No VAP" based on a predefined combination of clinical, radiological, and laboratory criteria. The microbiological yield from blood and ETA cultures was analyzed. RESULTS: Of 165 neonates who were ventilated for > 48 h, 65 were suspected of having VAP. Thirty-six (22.9%) were classified as VAP. Microbiological agents could be identified in 31 cases (86.1%) by ETA/blood cultures. Acinetobacter sp was the common organism identified. Duration of ventilation, and a higher number of reintubations before suspicion of VAP were significant risk factors for VAP. Positive ETA culture was associated with a greater duration of oxygen therapy and ventilation days after suspicion of VAP. CONCLUSIONS: The commonest culture yield from ETA in those suspected to have VAP was gram-negative bacilli. Duration of ventilation and reintubations were identified as significant risk factors for VAP. These are potentially modifiable factors. Positive ETA culture was associated with longer needs for respiratory supports. Negative ETA culture might encourage clinicians to stop antibiotics.

Effect of Early Parent Participation Program on Physiological Stability in Preterm Infants: A Randomized Controlled Trial.

OBJECTIVE: This research aimed to study the impact of early parent participation program (EPPP) for preterm infants in neonatal intensive care unit (NICU) on physiological instability, breastmilk feeding rates, and discharge timing. STUDY DESIGN: Families of 147 infants born between 28 and 33 weeks' gestation were randomized at birth to EPPP group or conventional care (CC). Families in the EPPP group were trained soon after admission by using a structured education program and encouraged to spend more time with their baby. Soon after enrolment (day of life 1 to 2), they would sequentially participate in daily NICU care processes such as orogastric tube feeding, nesting, oil massages, diaper changes, and daily weight checks. Families in the CC group would undergo the same after their infant was off parenteral nutrition and respiratory support. Proportion of infants having physiological instability (significant apnea, feeding intolerance, or needing investigation for sepsis) in two groups was compared. RESULTS: There was a significant reduction in the proportion of infants with physiological instability (feeding intolerance) in the EPPP group (relative risk = 0.70 [0.52-0.94], p = 0.016). Infants in EPPP group had a trend toward higher breastmilk feeding rates at discharge (66 vs. 51%, p = 0.076). CONCLUSION: Very early parent participation was feasible in the NICU and led to decrease in physiological instability in preterm infants. KEY POINTS: · Family-integrated care is beneficial; however, it is often started later in the NICU course.. · This trial showed that very early involvement of family in NICU care processes is feasible and safe.. · Structured parent participation started very early improves physiological stability in preterm infants (mainly tolerance to feeds)..

Iron Status of the Moderate and Late Preterm Infant: A Prospective Cohort Study.

Guidelines on micronutrient supplementation in moderate to late preterm infants (MLP) are mostly extrapolated from those for smaller preterms, largely due to lack of systematic studies on physiological status in this special group of infants. Actual practices vary widely. We prospectively studied iron status by measurement of serum ferritin (SF) and haematological indices at 4 months corrected age in infants born between 32 and 36 weeks gestation (MLP), after they received 2 mg/kg/day oral iron from 6 weeks of postnatal age. Proportion of MLP having normal iron status (iron replete), i.e., neither iron deficiency (ID) nor iron excess was measured. ID anaemia, growth and development, risk factors for ID were also analysed. Of the 82 infants studied, 78% babies were late preterm. Seventy-four (90.3%) were iron replete (no deficiency or excess) at 4 months. High variability in SF levels (minimum of 9.8 to maximum of 252.2 µg/l) with median (IQR) of 57.45 µg/l (37.02-98.85) was noted in the entire cohort; and also within those who were iron deficient with median (IQR) of 17.50 µg/l (11.70-18.90). There was no difference in haematological indices of ID infants when compared to those with normal iron status. Inspite of oral iron supplementation with reasonable compliance, 8.5% MLP were iron deficient at 4 months corrected age. The high variability noted in SF levels could justify the need for monitoring iron status in this group of preterm infants. This could quintessentially aid individualization of iron supplementation advice.

Duration of Caffeine for Apnea of Prematurity-A Randomized Controlled Trial.

OBJECTIVES: There is sufficient evidence to support use of caffeine therapy for apnea of prematurity, but practices vary widely when it comes to discontinuing therapy. This study was planned to compare 'recurrence of apnea of prematurity' (RAP); when 2 protocols were used to stop caffeine therapy. METHODS: Neonates delivered at 26-32 wk gestation on caffeine therapy for apnea of prematurity were randomized into 2 groups: Group 1-caffeine stopped at 7 d apnea-free period, and Group 2-continued for a prefixed period till at least 34 wk postmenstrual age (PMA). Proportion of infants in each group with RAP were analyzed. RESULTS: Each group consisted of 60 infants. Proportion of infants in each group with RAP, were not different (15% vs 13%); odds ratio (OR) 0.87; 95% confidence interval (CI) (0.31-2.43). Caffeine could be stopped earlier (33 vs 34 wk PMA); and cumulative duration of therapy was lesser (19.5 vs 33 d) when stopped at 7 d apnea-free period. Other studied outcomes were similar between the two groups. CONCLUSIONS: Mandatorily continuing caffeine therapy up to 34 wk PMA in select preterm groups does not seem to decrease risk of recurrence of apnea. Larger trials that specifically study extremely preterm infants are required to make robust recommendations on when to stop therapy.

Disability Prediction by Early Hammersmith Neonatal Neurological Examination: A Diagnostic Study.

BACKGROUND AND OBJECTIVES: Hammersmith Neonatal Neurologic Examination (HNNE) is used to identify term and preterm infants at risk of neurodevelopmental disability. The test is recommended at corrected term age in preterm; and around 2 weeks postnatal age in term neonates. As the current trend is to discharge based on physiological stability, it may not be feasible to perform HNNE at recommended age. The authors investigated whether predictive ability of the test for neurodevelopmental disability remained unchanged if performed early (before discharge). METHODS: The authors enrolled preterm and at-risk term neonates. HNNE PE was performed before discharge in all infants. The test was repeated in preterm infants at 40 weeks postmenstrual age and in term neonates at 2 weeks of age (HNNE RA). Neurodevelopmental disability was assessed at 1 year of age. RESULTS: HNNE PE was done in 125 neonates (103 preterm, 22 term neonates). HNNE RA was done in 58% infants. Neurodevelopmental disability was assessed in 84 (67%) of infants. Neurodevelopmental disability was noted in 14/84 (16.6%) babies. The receiver operating characteristic curve of raw scores showed that area under the curve for HNNE PE (0.71) and HNNE RA (0.66) were similar. The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio for both the tests were similar for a cutoff optimality score of 32.5. HNNE PE could be performed up to 4 weeks earlier than HNNE RA with the same predictive ability for neurodevelopmental disability. CONCLUSIONS: HNNE PE was as reliable as HNNE RA in predicting neurodevelopmental disability at 1 year of age. Completion of the test is assured and provides several weeks lead time for early intervention.
