ABSTRACT
OBJECTIVE: To evaluate the rates of practice, and the associations between different cord management strategies at birth (delayed cord clamping [DCC], umbilical cord milking [UCM], and early cord clamping [ECC]) and mortality or major morbidity, rates of blood transfusion, and peak serum bilirubin in a large national cohort of very preterm infants. STUDY DESIGN: We retrospectively studied preterm infants <33 weeks of gestation admitted to the Canadian Neonatal Network between January 2015 and December 2017. Patients who received ECC (<30 seconds), UCM, or DCC (≥30 seconds) were compared. Multiple generalized linear/quantile logistic regression models were used. RESULTS: Of 12 749 admitted infants, 9729 were included; 4916 (50.5%) received ECC, 394 (4.1%) UCM, and 4419 (45.4%) DCC. After adjustment for potential confounders identified between groups in univariate analyses, the odds of mortality or major morbidity were higher in the ECC group when compared with UCM group (aOR, 1.18; 95% CI, 1.03-1.35). Mortality and intraventricular hemorrhage were associated with ECC as compared with DCC (aOR, 1.6 [95% CI, 1.22-2.1] and aOR, 1.29 [95% CI, 1.19-1.41], respectively). The odds of severe intraventricular hemorrhage were higher with UCM compared with DCC (aOR, 1.38; 95% CI, 1.05-1.81). Rates of blood transfusion were higher with ECC compared with UCM and DCC (aOR, 1.67 [95% CI, 1.31-2.14] and aOR, 1.68 [95% CI, 1.35-2.09], respectively), although peak serum bilirubin levels were not significantly different. CONCLUSIONS: Both DCC and UCM were associated with better short-term outcomes than ECC; however, the odds of severe intraventricular hemorrhage were higher with UCM compared with DCC.

OBJECTIVE: To evaluate the significance and predictive value of each of the Neonatal Resuscitation Program (NRP)-listed ante- and intrapartum risk factors for the need of neonatal intubation at birth. STUDY DESIGN: In this population-based study, perinatal data of all infants born at ≥ 35 weeks gestation in the province of Nova Scotia between 1994 and 2014, were identified and reviewed from the Nova Scotia Atlee Database. The frequency of occurrence of risk factors, incidence of neonatal intubation at birth, and its relationship with the different NRP-listed risk factors, were examined. Variables that were significant (P < .05) in univariate analyses were entered into the regression model. RESULTS: During the 20-year study period, 176,365 infants ≥ 35 weeks gestation were born. In presence of any of the listed risk factors, 0.3% of infants received intubation at birth compared with 0.08% in absence of any risk factor (P < .001). On logistic regression analysis, only 16 of the NRP-listed risk factors had a significant relationship with intubation at birth (P < .001). Delivery in a tertiary care center did not have an impact. CONCLUSIONS: The presence of an intubation-skilled person at birth may not be indicated in all the NRP-listed ante- and intrapartum risk factors. Stratification of the relative significance of different risk factors may be of importance for the less-resourced health care units providing maternal and newborn care.

OBJECTIVES: To evaluate the frequency of central venous catheter (CVC)-related thrombi detected by routine surveillance ultrasound, and to assess whether positive findings had an impact on management or outcomes. STUDY DESIGN: All neonates in a tertiary neonatal intensive care unit who had a CVC inserted for >14 days underwent routine surveillance ultrasound biweekly between January 2003 and December 2009. Data were reviewed retrospectively. RESULTS: Although all neonates were asymptomatic at time of surveillance ultrasound, 645 of the total 1333 CVCs inserted in 1012 neonates underwent surveillance ultrasound, and thrombi were detected in 69 (10.7%). The CVCs with thrombi were more likely to be removed for nonelective reasons compared with CVCs without thrombi (59% vs 38%; P = .001; OR, 2.4, 95% CI 1.4-3.9). A total of 955 surveillance ultrasounds were performed to detect and monitor 69 CVCs with thrombi. The majority of thrombi were nonocclusive and nonprogressive. A change in management occurred in 8 cases of CVC-related thrombi (12%), or 1% of all screened cases. An average of 14 ultrasounds were required to detect and monitor 1 CVC with thrombus, at a cost of $951 per CVC with thrombus and $8106 per case of CVC-related thrombi with a change in treatment. CONCLUSION: Asymptomatic thrombi were detected in a significant proportion of CVCs by routine surveillance ultrasound. There were significant costs, but infrequent changes to patient management.
