Success and safety of neonatal endotracheal tube exchanges: a NEAR4NEOS multicentre retrospective cohort study
ObjectivesTo compare success and safety of endotracheal tube (ETT) exchanges with primary intubations and identify factors associated with ETT exchange outcomes.DesignRetrospective observational study of prospectively collected National Emergency Airway Registry for Neonates data. ETT exchanges are the placement of a new ETT when one is already in place, whereas primary intubations do not have a pre-existing ETT. The primary outcome was first-attempt success. Secondary outcomes included number of attempts, adverse tracheal intubation-associated events (TIAEs), severe TIAEs, desaturation and bradycardia. Descriptive statistics compared characteristics for ETT exchanges and primary intubations. Univariable and multivariable analyses compared primary and secondary outcomes and identified factors independently associated with ETT exchange outcomes.ResultsA total of 1572 ETT exchanges and 9999 primary intubations across 21 sites were included from October 2014 to September 2022. ETT exchanges represented 2.3%–31.2% (mean 13.6%) of intubations across sites. Patient, provider and practice characteristics varied significantly between ETT exchanges and primary intubations. In univariable analyses, ETT exchanges were associated with higher first-attempt success (70.5% vs 53.6%; p<0.001) and fewer safety events. In multivariable analyses, ETT exchanges were associated with an increased adjusted OR (aOR) of first-attempt success (1.71; 95% CI 1.57 to 1.86; p<0.001). ETT exchanges were associated with lower aOR of all safety outcomes except severe TIAEs. Factors independently associated with ETT exchange first-attempt success included video laryngoscopy and paralytic premedication.ConclusionCompared with primary intubations, ETT exchanges were associated with higher first-attempt success and fewer safety events. Video laryngoscope and paralytic premedication were associated with improved ETT exchange outcomes.
Fluid handling and blood flow patterns in neonatal respiratory distress syndrome versus transient tachypnea: a pilot study
Background Cardiovascular and renal adaptation in neonates with Respiratory Distress Syndrome (RDS) and Transient Tachypnea of the Newborn (TTN) may be different. Methods Neonates ≥32 weeks were diagnosed with RDS or TTN based on clinical, radiologic and lung sonographic criteria. Weight loss, feeding, urine output, and sodium levels were recorded for the first 3 days, and serial ultrasounds assessed central and organ Doppler blood flow. A linear mixed model was used to compare the two groups. Results Twenty-one neonates were included, 11 with TTN and 10 with RDS. Those with RDS showed less weight loss (− 2.8 +/− 2.7% versus − 5.6 +/− 3.4%), and less enteral feeds (79.2 vs 116 ml/kg/day) than those with TTN, despite similar fluid prescription. We found no difference in urine output, or serum sodium levels. Doppler parameters for any renal or central parameters were similar. However, Anterior Cerebral Artery maximum velocity was lower ( p  = 0.03), Superior Mesenteric Artery Resistance Index was higher in RDS, compared to TTN ( p  = 0.02). Conclusion In cohort of moderately preterm to term neonates, those with RDS retained more fluid and were fed less on day 3 than those with TTN. While there were no renal or central blood flow differences, there were some cerebral and mesenteric perfusion differences which may account for different pathophysiology and management.
Impact of outreach education program on outcomes of neonates with hypoxic ischemic encephalopathy
Abstract Aim To evaluate the impact of outreach education targeting neuroprotection on outcomes of outborn infants with moderate-to-severe hypoxic ischemic encephalopathy (HIE). Methods A retrospective cohort study of infants admitted with moderate-to-severe HIE was conducted following the implementation of outreach education in January 2016. Key interventions were early identification and referral of infants with encephalopathy utilizing telemedicine and a centralized communication system, hands-on simulation, and interactive case discussion and dissemination of clinical management guidelines and educational resources. The association between the intervention and a composite outcome of death and/or severe brain injury on brain magnetic resonance imaging (MRI) was tested controlling for the confounding factors. Results Of 165 neonates, 37 (22.4%) died and/or had a severe brain injury. This outcome decreased from 35% (27/77) to 11% (10/88) following the implementation of outreach education (P<0.001). Eligible infants not undergoing therapeutic hypothermia within 6 hours from birth decreased from 19.5% (15/77) to 4.5% (4/88). The use of inotropes decreased from 49.3% (38/77) to 19.6% (13/88). Any core temperature below 33°C was recorded for 20/53 (38%) before and 16/78 (21%) after, while those within the target range of 33°C to 34°C at admission to a tertiary care facility increased from (15/53) 28% to (51/88) 58%. Outreach education was independently associated with decreased composite outcome of death and/or severe brain injury on MRI (adjusted odds ratio 0.2; 95% confidence interval 0.07 to 0.52). Conclusion Outreach education targeting neuroprotection for infants with moderate-to-severe HIE was associated with a reduction in death and/or severe brain injury.
Outcomes of neonates born at <26 weeks gestational age who receive extensive cardiopulmonary resuscitation compared with airway and breathing support
ObjectiveTo evaluate outcomes of preterm infants <26 weeks gestational age (GA) following postdelivery extensive cardiopulmonary resuscitation (ECPR) compared with airway and breathing support (ABS).Study designRetrospective review of Canadian Neonatal Network data during January 2010 to December 2016. The primary outcome was death or severe morbidity (intraventricular hemorrhage ≥grade 3 or periventricular leucomalacia, retinopathy of prematurity ≥stage 3, bronchopulmonary dysplasia, or necrotizing enterocolitis).ResultAmong 3633 infants analyzed, 433 (11.9%) received ECPR. In multivariable analysis, death or severe morbidity was higher in the ECPR versus ABS group [adjusted odds ratio 2.26 (95% confidence interval 1.49, 3.43)]. The majority of the difference was due to increased mortality, which occurred mostly during the first week of life.ConclusionThese data from a recent cohort of infants near the limits of viability may be useful for prognostication for health care providers and counseling of parents.
Outcomes and care practices for preterm infants born at less than 33 weeks’ gestation: a quality-improvement study
Preterm birth is the leading cause of morbidity and mortality in children younger than 5 years. We report the changes in neonatal outcomes and care practices among very preterm infants in Canada over 14 years within a national, collaborative, continuous quality-improvement program. We retrospectively studied infants born at 23–32 weeks’ gestation who were admitted to tertiary neonatal intensive care units that participated in the Evidence-based Practice for Improving Quality program in the Canadian Neonatal Network from 2004 to 2017. The primary outcome was survival without major morbidity during the initial hospital admission. We quantified changes using process-control charts in 6-month intervals to identify special-cause variations, adjusted regression models for yearly changes, and interrupted time series analyses. The final study population included 50 831 infants. As a result of practice changes, survival without major morbidity increased significantly (56.6% [669/1183] to 70.9% [1424/2009]; adjusted odds ratio [OR] 1.08, 95% confidence interval [CI] 1.06–1.10, per year) across all gestational ages. Survival of infants born at 23–25 weeks’ gestation increased (70.8% [97/137] to 74.5% [219/294]; adjusted OR 1.03, 95% CI 1.02–1.05, per year). Changes in care practices included increased use of antenatal steroids (83.6% [904/1081] to 88.1% [1747/1983]), increased rates of normothermia at admission (44.8% [520/1160] to 67.5% [1316/1951]) and reduced use of pulmonary surfactant (52.8% [625/1183] to 42.7% [857/2009]). Network-wide quality-improvement activities that include better implementation of optimal care practices can yield sustained improvement in survival without morbidity in very preterm infants.
Impact of multiple intubation attempts on adverse tracheal intubation associated events in neonates: a report from the NEAR4NEOS
ObjectiveTo determine the relationship between number of attempts and adverse events during neonatal intubation.Study designA retrospective study of prospectively collected data of intubations in the delivery room and NICU from the National Emergency Airway Registry for Neonates (NEAR4NEOS) in 17 academic centers from 1/2016 to 12/2019. We examined the association between tracheal intubation attempts [1, 2, and ≥3 (multiple attempts)] and clinical adverse outcomes (any tracheal intubation associated events (TIAE), severe TIAE, and severe oxygen desaturation).ResultsOf 7708 intubations, 1474 (22%) required ≥3 attempts. Patient, provider, and practice factors were associated with higher TI attempts. Increasing intubation attempts was independently associated with a higher risk for TIAE. The adjusted odds ratio for TIAE and severe oxygen desaturation were significantly higher in TIs with 2 and ≥3 attempts than with one attempt.ConclusionThe risk of adverse safety events during intubation increases with the number of intubation attempts.
Impact of quality improvement outreach education on the incidence of acute brain injury in transported neonates born premature
ObjectiveTo evaluate impact of a quality improvement (QI) outreach education on incidence of acute brain injury in transported premature neonates.Study designNeonates born at <33 weeks gestation outside the tertiary center were included. The QI intervention was a combination of neuroprotection care bundle, in-person visits, and communication system improvement. Descriptive and regression (adjusting for Gestational Age, Birth Weight, Gender, and antenatal steroids, Mode of delivery, Apgars at 5 minutes, Prophylactic indomethacin, PDA, and Inotropes use) analyses were performed. The primary outcome was a composite of death and/or severe brain injury on cranial ultrasound using a validated classification.Results181 neonates studied (93 before and 88 after). The rate and adjusted odds of death and/or severe brain injury reduced significantly post intervention (30% vs 15%) and (AOR 0.36, 95%CI, 0.15–0.85, P = 0.02) respectively.ConclusionImplementation of outreach education targeting neuroprotection can reduce acute brain injury in transported premature neonates.
Congenital SARS-CoV-2 Infection in Two Neonates with Confirmation by Viral Culture of the Placenta in One Case
Congenital infections with SARS-CoV-2 are uncommon. We describe two confirmed congenital SARS-CoV-2 infections using descriptive, epidemiologic and standard laboratory methods and in one case, viral culture. Clinical data were obtained from health records. Nasopharyngeal (NP) specimens, cord blood and placentas when available were tested by reverse transcriptase real-time PCR (RT-PCR). Electron microscopy and histopathological examination with immunostaining for SARS-CoV-2 was conducted on the placentas. For Case 1, placenta, umbilical cord, and cord blood were cultured for SARS-CoV-2 on Vero cells. This neonate was born at 30 weeks, 2 days gestation by vaginal delivery. RT-PCR tests were positive for SARS-CoV-2 from NP swabs and cord blood; NP swab from the mother and placental tissue were positive for SARS-CoV-2. Placental tissue yielded viral plaques with typical morphology for SARS-CoV-2 at 2.8 × 102 pfu/mL confirmed by anti-spike protein immunostaining. Placental examination revealed chronic histiocytic intervillositis with trophoblast necrosis and perivillous fibrin deposition in a subchorionic distribution. Case 2 was born at 36 weeks, 4 days gestation. RT-PCR tests from the mother and infant were all positive for SARS-CoV-2, but placental pathology was normal. Case 1 may be the first described congenital case with SARS-CoV-2 cultivated directly from placental tissue.
