Umbilical cord milking versus delayed cord clamping in term and late-preterm infants: a systematic review and meta-analysis.

OBJECTIVE: To conduct a systematic review and meta-analysis to compare the efficacy and safety of umbilical cord milking (UCM) versus delayed cord clamping (DCC) in term and late-preterm infants. METHODS: MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, Clinical trial registries, and Gray literature were searched for randomized controlled trials (RCTs) comparing UCM with DCC in term and late-preterm infants for both short-term and long-term outcomes. Intact and cut UCM were compared separately with DCC using subgroup analysis. We used fixed effect model to pool the data. Random effects model was used when there was significant heterogeneity. RESULTS: Nine studies (1632 infants) were included in the systematic review. Milking was performed on intact cord (i-UCM) in five studies (n = 829) and on cut cord (c-UCM) in four studies (n = 803). Cord milking significantly improved hemoglobin level at 48-72 h of life when compared to DCC (six studies, n = 924, mean difference 0.36 g/dL; 95% CI: 0.19-0.53). In addition, hemoglobin level at six to eight weeks of age was also significantly higher in the studies comparing i-UCM with DCC (two studies, n = 550: mean difference 0.16 g/dL; 95% CI: 0.06-0.27). There was no difference between the UCM group and DCC group for any other outcome. Only one study provided information on growth and hematological parameters at one year of age. Neurodevelopmental outcomes were not reported. None of the studies included non-vigorous infants. The grade of evidence was low to very low for all the outcomes studied. CONCLUSION: UCM is comparable to DCC in improving short-term hematological outcomes in term and late-preterm vigorous infants. Trials assessing the effect of UCM on important clinical and long-term outcomes among non-vigorous mature preterm infants are urgently required.

Efficacy of transcutaneous bilirubinometry as compared to serum bilirubin in preterm newborn during phototherapy.

Transcutaneous measurement of bilirubin is being used for neonatal jaundice. Its utility during phototherapy in preterm babies is not established. The objective of our study was to assess the efficacy of transcutaneous bilirubin (TcB) measurement in comparison to total serum bilirubin in preterm newborns at admission and during phototherapy at the covered skin area (glabella). It was a prospective observational study and conducted at the neonatal intensive care unit of a tertiary care hospital from January 2017 to January 2019. One hundred eligible preterm neonates were enrolled. Babies who were very sick, with poor peripheral circulation, edematous, having conjugated hyperbilirubinemia, with major congenital malformations, already received phototherapy or exchange transfusion were excluded. Paired total serum bilirubin and transcutaneous bilirubin were measured at admission and 6 h and 24 h during phototherapy. TcB was measured from the area (glabella) covered by an eye protector during phototherapy. The sample for TsB was taken within 10 min of TcB measurement. The mean differences between TsB and TcB values at admission and 6 h and 24 h of phototherapy were - 0.005 (0.353) mg/dl, - 0.350 (0.611) mg/dl, and - 0.592 (0.353) mg/dl, respectively. At admission or before starting of phototherapy, the difference (TsB-TcB) was statistically not significant (p = .125), while the difference in these values was statistically significant at 6 h and 24 h of phototherapy.Conclusion: TcB measurements from the covered skin area in jaundiced preterm infants during phototherapy were not correlated with TsB and cannot be used as an alternate of serum bilirubin testing. What is known • HPLC bilirubin measurement is a gold standard test for bilirubin measurement but impractical for day to day use. Serum total bilirubin is used for clinical testing.. • There is evidence for use of transcutaneous bilirubinometry for assessment of bilirubin in term newborn. What is new • TcB measurements from a covered skin area in jaundiced preterm newborns under phototherapy were not correlated significantly at 6 h and 24 h of phototherapy, but correlated before phototherapy. • TcB cannot be used as an alternate of serum bilirubin testing in preterm infants during phototherapy.

Effect of T-Piece Resuscitator versus Self Inflating Bag on Arterial CO2 Levels in Preterm Neonates.

OBJECTIVE: To compare the effect of self-inflating bag (SIB) vs. T-piece resuscitator (TPR) on PaCO2 levels, when used for brief manual ventilation during administration of first dose of surfactant. METHODS: Preterm neonates were randomized to receive positive pressure ventilation with either self-inflating bag or T-piece resuscitator during administration of first dose of surfactant. Arterial blood gases were obtained at baseline and 1 h after the intervention. Primary outcome was the mean change in PaCO2 levels 1 h after the intervention. RESULTS: Eighty neonates were enrolled (40 in each group). The drop in PaCO2 at 1 h was significantly greater in the self inflating bag group as compared to the T-piece resuscitator group [8.96 ± 9.06 mmHg vs. 1.37 ± 9.06 mmHg, Mean difference = 7.58 mmHg, (95% CI: 3.78 to 11.4); P < 0.01]. The PaCO2 change was also statistically significant in the subgroup of infants that required only non-invasive ventilation. The need for second dose of surfactant was higher in the self-inflating bag group [77% vs. 55%, RR - 1.41 (95% CI: 1.02 to 1.94); P = 0.03]. CONCLUSIONS: T-piece resuscitator results in smaller reduction in PaCO2 levels compared to the self inflating bag, when used for brief manual ventilation during surfactant administration.

Ghosal Type Hematodiaphyseal Dysplasia.

BACKGROUND: Ghosal Type Hematodiaphyseal Dysplasia is an autosomal recessive disorder characterized by refractory anemia and diaphyseal bone dysplasia. CASE CHARACTERISTICS: A 3 y 9 mo-old male child presented with progressive anemia and bowing of thighs. Child was found to have a previously reported homozygous point mutation c.1238G>A, (p.Arg413Glu) in Exon 16 of TBXAS1 gene. OUTCOME: Low dose steroid therapy resulted in normalization of hemoglobin and prevented further progression of bony changes. MESSAGE: Refractory anemia in association with bony deformities should prompt pediatricians to investigate for inherited bony dysplasia.
