Falls in oxygen saturations accompany electrographic seizures in term neonates: an observational study.

Effective seizure detection is important however, clinical signs of seizure activity may be subtle in neonates. This study aimed to systematically investigate SpO2 and respiratory pattern changes associated with EEG seizures in term-born neonates. An observational study in term neonates at risk of seizures admitted to a single tertiary level neonatal intensive care unit. Synchronised high-resolution physiological data (ECG, pulse oximetry, respiration) and EEG/amplitude-integrated EEG (aEEG) monitoring were recorded. Sections of traces with evidence of clear EEG seizure activity were compared with physiological data recorded at the same time. 22/44 (50%) neonates who had aEEG monitoring were noted to have electrographic seizures. Physiologic download measurements were available for 11 of these neonates. In nine of these, an acute drop in oxygen saturation (SpO2) of at least 5% was noted in at least one seizure. Accompanying apnoeas were noted in three neonates. Acute decreases in SpO2 were seen in term neonates associated with seizures and these were not always accompanied by an apnoeic episode. Physiologic download in association with EEG monitoring may assist in improving seizure detection. Unexplained drops in SpO2 could indicate further investigation for possible seizures in at-risk neonates. A decrease in blood oxygen saturation (SpO2) associated with EEG seizures can occur in term infants with HIE or perinatal stroke. Drops in SpO2 associated with EEG seizures in term infants with HIE or stroke may occur in the absence of apnoeas. Unexplained acute falls in SpO2 in sick neonates may suggest possible seizures. Drops in SpO2 associated with seizures in term infants can occur over less than 3 minutes. Physiological monitoring alongside EEG monitoring could help to improve seizure detection.

The outcomes of specific surgically correctable congenital gastro-intestinal malformations at a tertiary level neonatal intensive care unit in South Africa

Background: The outcome of neonates with congenital surgically correctable gastro-intestinal (GIT) malformations is poorly described in low middle income countries. Methods: A 5-year retrospective descriptive analysis of neonates admitted to a tertiary level neonatal intensive care unit (NICU), with congenital, surgically correctable GIT malformations, was performed. The primary outcome was the 30-day postoperative mortality as well as survival to 1 year. Secondary outcomes included patient demographics, clinical presentation as well as the burden of disease in our study population. Results: Eighty-four neonates met study criteria. The mean gestational age was 35 weeks (SD 3.19) and birthweight 2518g (SD 789.3). The most common congenital malformations were intestinal atresia (39%) followed by omphaloceles (21%). Associated systemic malformations were common (39%). The majority of neonates (88%) underwent surgery at a median age of 2 days (IQR 1.5-5). Ventilation was required in 19% of neonates preoperatively and 65% postoperatively. Full feeds were achieved at a median age of 13 days (IQR 9-18) after surgery. The 30 day-postoperative survival rate was 97% with a survival to discharge or transfer of 86%. Data for one year survival was available for 80% of neonates with a one-year survival rate of 75%. Conclusion: The 30-day postoperative survival was high in neonates with congenital, surgically correctable GIT malformations. Outcomes and burden on the healthcare system was dependent on the type of lesion. With early diagnosis and referral to a tertiary centre, good outcomes can be achieved. Neonates with congenital GIT malformations should have long term follow up to monitor growth and neurodevelopment as well as to address the high mortality post discharge.

Reduction of Environmental Noise Impact on Preterm Babies in NICU by Using Ear Plugs

Objective − To determine if using ear plugs reduce the impact of noise on preterm babies admitted to neonatal intensive care units in terms of changes in their vital parameters and their discomfort level, assessed using the Neonatal Infant Pain Scale (NIPS) score.Materials and Methods − This is an interventional study conducted in a tertiary level neonatal intensive care unit (NICU) (Bangalore, India) over a period of 3 months, ranging from June 2022 to September 2022. This study included 20 preterm babies with different gestational ages and birth weights who were admitted to the NICU during that period. The babies’ response to noise, in terms of changes in heart rate, respiratory rate, blood pressure, oxygen saturation and discomfort level, were assessed with ear plugs and without ear plugs on alternate days and the results were recorded. Descriptive statistics were used for statistical analysis. Results − On days 1 and 3, mean heart rate and systolic blood pressure were lower in babies wearing ear plugs (141.55±2.42 SD and 60.1±11.58, respectively) than in the same babies without ear plugs (157.55±2.52 SD and 61.85±1.6 SD, respectively) on days 2 and 4. The mean oxygen saturation was higher in babies wearing ear plugs (96.7%±0.80 SD) than in the same babies without the intervention (93.75%±1.29 SD). The mean NIPS score was lower with the intervention (2.05±0.22) than without ear plugs (5.05±0.22 SD).Conclusion – Ear plugs were an effective alternative in situations where noise in the NICU cannot be consistently maintained at a lower level than the standard recommendation by the AAP of 45 decibels.

70 Purpose-built Catheters for Minimally Invasive Surfactant Therapy – Experience from a Canadian Tertiary Level Neonatal Intensive Care Unit

Abstract Background Surfactant delivery via a thin endotracheal catheter during spontaneous breathing (a technique called minimally invasive surfactant therapy [MIST]), is an increasingly popular alternative to intubation and surfactant administration. Procedural details among different centres vary, with marked differences in the choice of catheter to instill surfactant. Studies report use of feeding catheters, multiaccess catheters and vascular catheters for this purpose. Recently, purpose-built catheters for MIST received regulatory approval in Canada and became available for use. Procedural differences and user experiences between such catheters have not been described. Objectives The aim of this study was to describe procedural success, procedural adverse effects and user experience pertaining to two different types of purpose-build catheters (BLEScath™ and Surfcath™) for surfactant administration. Design/Methods This was a retrospective review of prospectively collected data at a tertiary care neonatal intensive care unit (NICU) in Southwestern Ontario. Neonates who received MIST using purpose-built catheters between January 1, 2021 and March 31, 2022 were included. Two types of purpose-built catheters were used in this time period: Surfcath™ and BLEScath™. Relevant baseline characteristics and data on procedural details (premedication, type of catheter) were collected. The procedural success, number of attempts and adverse effects among neonates who received MIST via Surfcath™ and those who received surfactant via BLEScath™ were compared, using chi-square tests or Fisher’s tests, as appropriate. User experience was described using an ease-of-use scale. Descriptive reports of user experience were collected and explored for themes/patterns. P-values <0.05 were considered statistically significant. Results 37 neonates met eligibility criteria; 22 received MIST via Surfcath™, whereas 15 received MIST via BLEScath™. Success rates were 91% in SurfCath™ and 93% in BLES-Cath (P> 0.994). Failed attempts were lower in Surfcath™ (23%) compared with BLEScath™ (33%), but the difference was not statistically significant (p=0.708). Upon analyzing ease-of-use by operators, we found that 90% of operators found Surfcath™ very easy or relatively easy to use, compared with 43% of users reflecting the same degree of use with BLEScath™ (P=.021). Users described difficulty in ‘maneuvering’ the BLEScath™ and reported it to be ‘pliable/ flimsy’. There was no difference in adverse events between groups. Conclusion This is the first study in Canada to report the experience of MIST with purpose-built catheters. Overall success rate was equally high for both catheters. Users subjectively reported higher ease of use with SurfCath™. Commercially available purpose-built catheters should facilitate universal adaptation of the MIST method. Our reports regarding operator experience may help with optimizing future product design to improve ease-of-use.

Impact of Targeted Neonatal Echocardiography on Patent Ductus Arteriosus Management in a Canadian Tertiary Care Neonatal Unit: A Retrospective Cohort Study.

Comprehensive assessment of hemodynamic significance of a patent ductus arteriosus (PDA) is a common indication to perform targeted neonatal echocardiography (TNE). Impact of implementation of such an assessment on PDA management decisions remains to be reported. The objective of this study is to compare PDA-related hemodynamic information and PDA treatment decisions before and after introduction of TNE service. This was a retrospective cohort study at a tertiary level neonatal intensive care unit in Southwestern Ontario. We investigated two time periods: Epoch-1 (non-TNE 2013-2016) versus Epoch-2 (TNE 2018-2021). We included neonates < 32 weeks with PDA. Data on baseline clinical characteristics, PDA-related echocardiographic parameters, PDA treatment details, and relevant long-term outcomes were collected. Primary outcome was defined as PDA treatment rates and need for multiple courses. Secondary outcomes included availability of PDA hemodynamic data and neonatal mortality/morbidity (PDA-related) RESULTS: A total of 275 neonates were included. A total of 162 were assessed by conventional echocardiography in Epoch-1, whereas 113 were assessed by TNE in Epoch-2. Baseline clinical characteristics were similar. Epoch-2 had more echocardiographic assessments per patient of 2.7 (±1.8) versus 1.9 (± 1.3), p < 0.001 in Epoch1. The mean postnatal age at first echocardiographic assessment was higher in Epoch-2 (12.7 days [ ± 14.6]) than in Epoch-1 (7.9 days [ ± 10.4]), p < 0.001. Comprehensive hemodynamic assessment of PDA-related echocardiographic parameters such as PDA size, shunt pattern, effect on systemic circulation, and pulmonary circulation were higher in Epoch-2. Overall, PDA treatment rates were comparable in the two time periods. The use of multiple courses of treatment was higher in Epoch-1 than in Epoch-2 (47.8 vs. 31.7%, p = 0.047). In Epoch-1, neonates received PDA treatment earlier than in Epoch-2. With the implementation of the TNE service, increased echocardiographic evaluations per patient were completed with availability of more comprehensive hemodynamic information about PDA. PDA treatment rates were similar in the two epochs, but need for multiple courses were less in TNE era. · TNE allows comprehensive hemodynamic assessment of PDA.. · Implementation of dedicated TNE service led to increased use of echocardiography to assess PDA.. · Standardized hemodynamic assessment of PDA may allow improved individualization of treatment need..

Erythrocyte transfusions are associated with retinopathy of prematurity in extremely low gestational age newborns.

Retinopathy of prematurity (ROP) is a major morbidity in preterm infants causing visual impairment including blindness. Prevention and timely treatment are critical. We investigated the potential role of red blood cell (RBC) transfusions as risk factor for ROP development. Retrospective cohort study of data from 68 tertiary level neonatal intensive care units in Germany. Preterm infants born at 22 + 0 to 28 + 6 weeks of gestation between January 2009 and December 2021 were enrolled. We included n = 12 565 infants. Prevalence of any ROP was 49.2% with most infants being diagnosed with stage 1 (21.5%) and 2 disease (17.2%). ROP stage 3 was present in 10.2%, stage 4 in 0.3%, and ROP requiring treatment in 6.6%. Infants with ROP had significantly more frequently a history of RBC transfusions. Adjusting for confounders, RBC transfusions were associated with increased odds of ROP (OR 1.4, p < 0.001), ROP progression (OR 2.1, p < 0.01) and ROP requiring treatment (OR 3.6, p < 0.001). Restrictive transfusion approaches correlated with decreased (OR 0.7, p < 0.001), liberal regimes with increased odds (OR 1.2, p = 0.001). The present study confirmed an association of RBC transfusions and ROP. Our findings emphasise the need for anaemia prevention and critical re-evaluation of transfusion practices in preterm infants.

Purpose Built Catheters for Minimally Invasive Surfactant Therapy: Experience from a Canadian Tertiary Level Neonatal Intensive Care Unit.

Minimally invasive surfactant therapy (MIST), a method of surfactant delivery via a thin catheter during spontaneous breathing, is an increasingly popular alternative to intubation and surfactant administration. Recently, purpose-built catheters for MIST received regulatory approval in Canada and became available for use. However, procedural success and user experience with such catheters have not been described. This retrospective cohort study included neonates who received MIST using purpose-built catheters between January 1, 2021, and March 31, 2022. Two types of purpose-built catheters were used in this period - SurfCath™ and BLEScath™. Procedural success, number of attempts, and adverse events in neonates receiving MIST via the two catheters were compared using chi-square or Fisher's tests. User experience was described using an ease-of-use scale. Thirty-seven neonates met eligibility criteria; 22 received MIST via SurfCath™, whereas 15 received MIST via BLEScath™. Success rates were 91% in SurfCath™ and 93% in BLEScath™ (P> 0.994). Failed attempts were lower in SurfCath™ (23%) in comparison to BLEScath™ (33%), but the difference was not statistically significant (P=0.708). Among operators, 90% found SurfCath™ very easy/relatively easy to use compared to 43% of users reflecting the same degree of use with BLEScath™ (P=.021). There was no difference in adverse events. This is the first study in Canada to report MIST with purpose-built catheters. Overall, the success rate was equally high with both catheters. Users subjectively reported higher ease of use with SurfCath™. Commercially available purpose-built catheters should facilitate universal adaptation of the MIST method.

Pattern of microbial profile and their susceptibility pattern in a tertiary level neonatal intensive care unit, Dubai, UAE: 11 years surveillance study

Introduction: Neonatal sepsis is a global burden on the health and wellbeing of the neonates. It mounts too many neonatal mortality and morbidity. However, rational use of antimicrobial therapy and aggressive supportive management has modified the outcome over the past few decades. A good knowledge of locally prevalent microbes and antibiotics sensitivity pattern help in formulating antibiotics regimen. Methodology: This study is a retrospective analysis of prevalent microorganisms isolated from various culture samples collected from neonates aged 0 - 90 days, suspected to have early or late onset neonatal sepsis. All the neonates were admitted to Neonatal intensive care unit (NICU) of Latifa Women and Children Hospital (LWCH) over an 11 year period (from January 2011 till December 2021). Descriptive analyses were used with results presented as proportions. Data were analyzed using Microsoft excel 2016 and online calculators. Results: A total of 4849 microbial culture positive isolates were identified from our NICU. These isolates included samples taken from, blood, cerebrospinal fluid, endotracheal aspirates, throat/nasopharynx, urine, rectal, stool, eyes and superficial cultures. Gram-negative bacteria were isolated in 56.3% (n= 2730). Gram positive bacteria accounted for 43.7% (n=2119) of isolates. Most common isolated bacterial species were Klebsiella pneumoniae (15.7%), Coagulase Negative Staphylococcus (CONS) (14.6%), Stenotrophomonas maltophilia (11.5%) and Pseudomonas aeruginosa (11.1%). Among the multidrug resistant organism (MDRO), Extended spectrum beta lactamase (ESBL) K. pneumoniae (n=208, 4.3%) and Methicillin resistant staphylococcus aureus (MRSA) (n=145, 3%) are the predominant strain. Over the study period, there is a significant reduction in both gram positive and gram negative bacterias (n=1055 in 2011 to 226 in 2021). Discussion/conclusion: The need of the hour is implementation of strict infection control measures and rationalized use of broad-spectrum antibiotics and continuous surveillance of emergence of MDROs. Regular tracking of the microbiological prevalence pattern kept us updated regarding prevailing organisms and emergence of MDROs. Our NICU antimicrobial policy modified in accordance with the surveillance data.

Influences of Initial Empiric Antibiotics with Ampicillin plus Cefotaxime on the Outcomes of Neonates with Respiratory Failure: A Propensity Score Matched Analysis

Background: Empiric antibiotics are often prescribed in critically ill and preterm neonates at birth until sepsis can be ruled out. Although the current guideline suggests narrow-spectrum antibiotics, an upgrade in antibiotics is common in the neonatal intensive care unit. The impacts of initial broad-spectrum antibiotics on the outcomes of critically ill neonates with respiratory failure requiring mechanical intubation have not been well studied. Methods: A total of 1162 neonates from a tertiary level neonatal intensive care unit (NICU) in Taiwan who were on mechanical ventilation for respiratory distress/failure at birth were enrolled, and neonates receiving ampicillin plus cefotaxime were compared with those receiving ampicillin plus gentamicin. Propensity score-matched analysis was used to investigate the effects of ampicillin plus cefotaxime on the outcomes of critically ill neonates. Results: Ampicillin plus cefotaxime was more frequently prescribed for intubated neonates with lower birth weight, higher severity of illness, and those with a high risk of early-onset sepsis. Only 11.1% of these neonates had blood culture-confirmed early-onset sepsis and/or congenital pneumonia. The use of ampicillin plus cefotaxime did not significantly contribute to improved outcomes among neonates with early-onset sepsis. After propensity score-matched analyses, the critically ill neonates receiving ampicillin plus cefotaxime had significantly worse outcomes than those receiving ampicillin plus gentamicin, including a higher risk of late-onset sepsis caused by multidrug-resistant pathogens (11.2% versus 7.1%, p = 0.027), longer duration of hospitalization (median [IQR], 86.5 [47-118.8] days versus 78 [45.0-106.0] days, p = 0.002), and a significantly higher risk of in-hospital mortality (14.2% versus 9.6%, p = 0.023). Conclusions: Ampicillin plus cefotaxime should not be routinely prescribed as the empiric antibiotics for critically ill neonates at birth because they were associated with a higher risk of infections caused by multidrug-resistant pathogens and final worse outcomes.

Manual Method vs Breast Pump for Breast Milk Expression in Mothers of Preterm Babies During First Postnatal Week: A Randomized Controlled Trial

ObjectivesTo compare breast milk volume between manual method and breast pump expression in mothers of preterm infants at different time point of first week.DesignRandomized controlled trial.SettingPostpartum ward of Obstetrics department and tertiary level neonatal intensive care unit (NICU) in a single institution in Orissa between October, 2020 and May, 2021.ParticipantsMothers who delivered before 34 completed weeks of gestation.InterventionsManual breastmilk expression (ME) group using Marmet technique and breast pump milk expression (PE) group using pigeon manual breast pump, initiated milk expression within one hour of delivery.Outcome measuresExpressed breast milk (EBM) volume in mothers of preterm infants at different time point of first week, and cumulative milk volume.ResultsOut of 170 mothers (83 PE and 87 ME group), 7-days milk volume data was available for 137 (71 ME and 66 PE) mothers. In per protocol analysis for 126 mothers (63 in each group), the median (IQR) EBM volume on day 2 and day 7 of ME and PE groups were similar [10 (5,20) vs 12 (5,28), P=0.10] and [280 (220–356) vs 280 (220–360), P=0.66]. The median (IQR) cumulative EBM volume over first 7 days in ME group was not significantly different from PE group [733 (593–995) vs 848.5 (571–1009)] P=0.55). A similar number of mothers in the PE and ME group [56 (88.9%) vs 58 (92%); P=0.14] provided exclusive breast milk for their neonates during the first week. Similar results were found on intention to treat analysis.ConclusionEBM volume expressed was comparable between mothers expressing manually or with breast pump.

138 Fluid overload in newborns undergoing abdominal surgery

Abstract Primary Subject area Neonatal-Perinatal Medicine Background Infants undergoing abdominal surgery, particularly those born preterm, are at risk of postoperative fluid overload and acute kidney injury due to immature cardiac and renal functions, which could contribute to increased morbidity and mortality. Objectives The purpose of this study was to evaluate the burden of fluid overload and acute kidney injury among newborns undergoing abdominal surgery and the association with adverse neonatal outcomes. Design/Methods Newborns who had undergone laparotomy from January 2017 to June 2019 admitted to a tertiary level Neonatal Intensive Care Unit were included in this retrospective cohort study. Fluid overload was assessed by the maximum percentage change in body weight and the difference between actual and prescribed fluid intake post-operatively. Acute kidney injury was defined as an increase in serum creatinine &amp;gt;1.5 times of baseline or &amp;gt;26 mmol/L, or oliguria (&amp;lt; 0 .5mL/kg/hr over 24-hour). Results There were 60 eligible infants with medians [IQR] gestational age (GA) and birth weight being 29 weeks [25–36] and 1240 grams [721–2871], respectively. Indications for laparotomy included small bowel obstruction (45%), necrotizing enterocolitis (23%), and large bowel obstruction (11.7%). In the first three post-operative days, 24/60 (40%) required inotropes, 5/59 (8.5%) had hyponatremia (&amp;lt;130 mmol/L), and 15/31(48.4%) developed hypoalbuminemia (&amp;lt;20 g/L). 52/60 (86.7%) infants had serum creatinine measured and 4 (6.7%) fulfilled our AKI criteria. The median of actual fluid intake was significantly higher than the prescribed fluid intake in the first 7 post-operative days (p&amp;lt;0.01) [Figure 1]. Medians [IQR] of maximum % change of body weight within the first 3- and 7-days post operation were 6 [3–13] and 11 [5 –17], respectively. While we did not identify any associations between post-operative fluid overload and mortality/bronchopulmonary dysplasia in this cohort, we found that every 1% increase in weight gain within the first 3 days post-operation were associated with an increase in 0.6 day of invasive ventilator support (p=0.012) [Figure 2]. Such correlation still exists after adjusting for GA (p=0.033). Conclusion In our cohort of newborns undergoing abdominal surgery, weight gain within the first three post-operative days was associated with an increase in duration of invasive ventilator support. Fluid overload does not seem to be associated with acute kidney injury. Careful attention to intra and early postoperative fluid balance may play an important role in optimizing outcomes of newborns undergoing abdominal surgery.

Clinical characteristics and outcomes of neonates with polymicrobial ventilator-associated pneumonia in the intensive care unit

BackgroundVentilator associated pneumonia (VAP) caused by more than one microorganisms is not uncommon and may be potentially challenging, but the relevant data is scarce in ventilated neonates. We aimed to investigate the clinical characteristics and outcomes of polymicrobial VAP in the neonatal intensive care unit (NICU).MethodsAll neonates with definite diagnosis of VAP from a tertiary level neonatal intensive care unit (NICU) in Taiwan between October 2017 and September 2020 were prospectively observed and enrolled for analyses. All clinical features, therapeutic interventions and outcomes were compared between the polymicrobial VAP and monomicrobial VAP episodes. Multivariate regression analyses were used to find the independent risk factors for treatment failure.ResultsAmong 236 episodes of neonatal VAP, 60 (25.4%) were caused by more than one microorganisms. Polymicrobial VAP episodes were more likely to be associated with multidrug-resistant pathogens (53.3% versus 34.7%, P = 0.014), more often occurred in later days of life and in neonates with prolonged intubation and underlying bronchopulmonary dysplasia. Otherwise most clinical characteristics of polymicrobial VAP were similar to those of monomicrobial VAP. The therapeutic responses and treatment outcomes were also comparable between these two groups, although modification of therapeutic antibiotics were significantly more common in polymicrobial VAP episodes than monomicrobial VAP episodes (63.3% versus 46.2%; P < 0.001). None of any specific pathogens was significantly associated with worse outcomes. Instead, it is the severity of illness, including presence of concurrent bacteremia, septic shock, and requirement of high-frequency oscillatory ventilator and underlying neurological sequelae that are independently associated with treatment failure.ConclusionsPolymicrobial VAP accounted for 25.4% of all neonatal VAP in the NICU, and frequently occurred in neonates with prolonged intubation and underlying bronchopulmonary dysplasia. In our cohort, most clinical features, therapeutic responses and final outcomes of neonates with monomicrobial and polymicrobial VAP did not differ significantly.

Outcomes for Newborns with Mild Hypoxic-Ischemic Encephalopathy: A Retrospective Study

Background: HIE remains a significant cause of mortality and long-term disability in late preterm and term newborns. At birth, the only available distinction between mild, moderate, and severe HIE is based on the clinical ground. Nevertheless, mild HIE can be presented with subtle or subjective clinical features which may mislead the treating physician and delay his decision to intervene. Methods: This is a retrospective descriptive study examined all inborn newborns ≥ 35 weeks gestational age born at a single, tertiary level Neonatal Intensive Care Unit (NICU) in women’s hospital. The study revised newborns who were admitted to NICU during the period from November 2014 till November 2020 under the diagnoses of mild HIE. The decision to start therapeutic hypothermia in cases of mHIE was off-label and it was taken according to the clinical judgment of the treating team. Results: Out of the 265 newborns admitted with a history suggestive of HIE or neurological deficits, only 116 newborns matched the diagnosis of mHIE according to the above-mentioned exclusions. 19 newborns out of the 116 mHIE cases received therapeutic hypothermia. Antepartum and or intrapartum complications were recorded in 48 mothers including an infant of insulin-dependent diabetic mother 12, pre-eclampsia 3, cord prolapse 2, shoulder dystocia 2, antepartum hemorrhage 8, chorioamnionitis 6, poor CTG tracing 13, and ruptured uterus 2. Mean gestation was 38±2 weeks, mean birth weight was 3.0±0.5 kg, Cesarean section was 57 % in the un-cooled group vs 75% in the cooled group. Mean Apgar score at 10th minute was 7.9±1.8 vs 5.3±2.2 in the un-cooled vs cooled group, the p-value is 0.002. Arterial cord pH was 7.15±0.3 vs 6.92±0.26. The base deficit in the first-hour blood gas was -7.83±5 vs -12± 5.6 (P=0.005). The Total number of cooled newborns was 19 (16%). Respiratory support was required in 76% of un-cooled newborns vs 95 % of cooled newborns. Most of the newborns have achieved full sucking power within 10 days (99%). Cooled newborns had to stay longer in the NICU because of the added number of cooling where the length of stay was 11±4.7 days vs 6.9±4.7 days in un-cooled newborns. The MRI brain was done on 25 newborns, 12 MRIs were reported as abnormal (48 %) and consistent with hypoxic-ischemic changes, 5/97 in the un-cooled cases and 7 in the cooled cases. Neurodevelopmental assessments at 12 months and 18 months of age were abnormal in 14/116 newborns (12%). Conclusion: The current assumptions about the benignity of mild form of HIE may not be accurate. More attention to this category of HIE, clear diagnostic criteria, longer clinical observation, and vigilant neurological assessment are all required.

Impact of Kangaroo mother care on the maintenance of temperature and weight gain of newly born low birth weight babies

In preterm and LBW infants, skin-to-skin contact between the mother and her infant decreases maternal postpartum depressive symptoms and improves self-efficacy and mother-child bonding. However, evidence supporting it is lacking. To evaluate the impact of Kangaroo Mother Care (KMC) on the maintenance of temperature and weight gain of newly born low birth weight babies. Fifty newborn babies weighing less than 1.8 kgs were studied at a tertiary level neonatal intensive care unit (NICU)from August 2013 to August 2014. An equal number of new-borns from the same setting, matched for weight and gestational age received routine care (warmer) and acted as controls. A special bag or kangaroo pouch was designed to keep the baby in close contact with the mother to provide KMC. Weight gain and temperature maintenance were studied. Maximum number of cases and control was 1-10 days old. A maximum number of cases and controls were babies between 1.251 to 1.800 kgs i.e. 70% and 72% respectively. In the KMC group, the majority (52%)had weight gain between 100-200gm, while in the control group 52% of subjects had weight gain between 0-100 gm. Maximum number of babies in KMC group (52%) gained 15.1-20gm/day vs 0-5 gm/day in controls (42%). 70% of the KMC group while 66% of the control group was discharged between 1.25-1.5 kg weight. The pre-intervention mean temperature in neonates of the case group was 35.99 ± 0.59 °F, while the post-intervention mean temperature in the case of group neonates was 37.01 ± 0.22 °F. Thus, the neonates in the case group had gained temperature after the intervention (p&amp;#60;0.001).The babies in the KMC group demonstrated more weight gain and temperature.

The effect of kangaroo mother care on aEEG activity and neurobehavior in preterm infants: a randomized controlled trial

Objective To evaluate the effect of kangaroo mother care (KMC) versus traditional care (TC) on aEEG activity and neurobehavior in preterm infants. Methods A prospective randomized control single-blinded trial conducted in a tertiary level neonatal intensive care unit between October 2019 and October 2020. Preterm infants with gestational age of 31–33 weeks were randomly divided into either a KMC group or a TC group. Outcomes were compared between the groups including aEEG scores, the percentage of mature sleep–wake cycling (SWC) and background activity continuity, narrowband upper and lower bound amplitude, narrowband bandwidth, and neonatal behavioral neurological assessment (NBNA) scores on day 1, day 7, and day 14 after randomization. Results A total of 65 infants (32 in KMC group and 33 in TC group) completed protocol. No significant differences were observed in outcomes on day 1. aEEG scores (p = .027 and p = .007, respectively) and the percentage of mature SWC (p = .034 and p = .039, respectively) were significantly higher in KMC group on day 7 and day 14. Compared to the TC group, KMC group had a narrower bandwidth on day 7 (p = .003) and day 14 (p = .016) and higher lower bound amplitude on day 14 (p = .002). Upper bound amplitude and the percentage of continuity were comparable between the groups on day 7 and day 14. The NBNA scores in the KMC group were significantly higher than that of the TC group on day 7 (p < .001) and day 14 (p < .001). Conclusions Preterm infants submitted to the KMC, compared to those non-submitted, have more mature aEEG activity and better neurobehavior performance on day 7 and day 14 after random.

Predictive validity of the Lacey Assessment of Preterm Infants for motor outcome at 2 years corrected age

IntroductionThe Lacey Assessment of Preterm Infants (LAPI) is a clinical tool used to assess neuromotor development in preterm infants at high risk of developmental problems. The aim of this study was to determine its predictive validity for estimating later motor outcome at 2 years of age, to ensure appropriate referral to early intervention and thus optimise the infant's outcome. MethodLAPI outcomes (usual or monitor) for preterm infants born between January 2012–2017 at a single tertiary level neonatal intensive care unit in London, UK were retrospectively reviewed. Predictive validity for later “moderate/severe” motor delay was determined by comparing LAPI outcomes with locomotor scores estimated using the Griffiths Mental Development Scales-Extended Revised (GMDS-ER) or Griffiths III at 2 years corrected age. Results118 infants were included (GMDS-ER = 87, Griffiths III = 31). Infants classified as usual on the LAPI showed significantly less motor delay on the GMDS-ER locomotor subset at 2 years, compared to infants in the monitor group (usual = 2.00 months, monitor = 6.00 months; p = 0.001). Sensitivity was found to be only 47.37%, with higher specificity of 84.85%. ConclusionThe LAPI shows high specificity but low sensitivity for prediction of later motor delay. It may therefore be useful for screening lower-risk infants, however on-going monitoring would be advised. Further studies investigating the reliability of the LAPI and use in conjunction with other predictive tools to improve sensitivity are recommended.

BackgroundBlood loss and adult blood transfusions are common during the neonatal period in preterm infants. The objective of the study was to clarify if degree of loss of fetal haemoglobin...

Understanding umbilical venous catheter insertion practices through a prospective multicenter observational study

Objective To understand practices of umbilical venous catheter (UVC) insertion in tertiary level neonatal intensive care units (NICU) and investigate the outcomes of subsequent attempts following a failed initial attempt. Study design Prospective, multi-center observational study of UVC insertions at tertiary level NICUs between March 2019 and January 2020. Results Of the 101 UVCs inserted at 4 centers, seventy-two (71%) were central at the first attempt and 50% were central at subsequent attempts. Patients with at least 1 failed attempt at insertion were less likely to have a centrally placed UVC (p = .009). Manipulations were less likely to be required when UVC was centrally placed during the first attempt. Maneuvers such as posterior liver mobilization used during insertion were likely to be associated with successful central placement of UVC (p = .0243). The time to complete the procedure was significantly less when the UVC was central at the first attempt (34.2 ± 20.2 vs 46.9 ± 33.8) (p = .0292). Gestational age, birth weight, and age of the baby at the insertion of the UVC, experience of the provider, and type of catheter were comparable among groups. The Shukla formula was most commonly used by providers to measure the depth of UVC placement. Conclusion Repetitive attempts and manipulations were less likely to be beneficial in the successful central placement of UVC in neonates. Additionally, repetitive attempts at insertion prolonged the overall duration of the procedure.

Meningitis Trends and Association With Intraventricular Hemorrhage in Very Preterm Infants

Background: Meningitis is often considered to be a subset of neonatal infections that should respond to infection control strategies; however, a preliminary report from the Canadian Neonatal Network (CNN) indicated that an infection control program decreased late onset sepsis but not meningitis. There was also no significant decrease in the incidence of severe neurological injury. We aimed to compare trends in the incidence of late onset sepsis and meningitis among very preterm infants in Canada, and to determine whether there is an association between late onset meningitis and intraventricular hemorrhage (IVH). Methods: All very preterm infants <33 weeks gestational age admitted to tertiary level neonatal intensive care units (NICUs) in the CNN from 2010-2018 were included. Statistical analyses were performed to compare the trends for incidence rates of late onset culture positive bloodstream infection (CPBSI) and late onset meningitis, and to examine the association of meningitis and IVH (exposure), after adjustment for patient risks. Findings: Of 36,573 infants in this study, 32,198 had no infections, 3977 had only late onset CPBSI and 398 had late onset meningitis. Between 2010 and 2018, there was a significant decrease in the incidence of late onset CPBSI (rates decreased from 14% to 11%; (AOR)=0.93; 95%CI 0.92, 0.95) but not for late onset meningitis (rates were not significantly changed from 1.5% to 1.2%; (AOR)=0.98; 95%CI 0.94, 1.01). Infants with IVH grade 3 or above had higher odds of late onset meningitis compared with infants with no infection (AOR 4.16; 95%CI 3.17, 5.44), and infants with late onset CPBSI (AOR 4.11; 95%CI 3.08, 5.50). Interpretation: There was a decreasing trend of late onset CPBSI but not meningitis. An association between late onset meningitis and IVH was observed. Late onset CPBSI and meningitis may have different risk factors and require different prevention strategies.
