Infection and complication rates were similar between infants managed with an umbilical vein catheter in place for up to 28 days compared with infants managed with an umbilical vein catheter replaced by a percutaneous central venous catheter after 7 to 10 days. Umbilical vein catheter durations beyond the current Centers for Disease Control and Prevention-recommended limit of 14 days may be reasonable.

DPNB provides better pain reduction during neonatal circumcision than EMLA cream. EMLA cream may provide pain reduction compared with no anesthesia during neonatal circumcision.

BackgroundThrombosis in neonates is a rare but serious occurrence, usually associated with central catheterization. The objective of this study was to investigate the risk factors associated with catheter related thrombosis in very low birth weight (VLBW) infants.ProcedureThe present retrospective study was performed using data from a randomized trial of duration of umbilical venous catheters (UVC) placement among infants <1,250 g birth weight. Twenty‐two cases of UVC‐associated thrombosis were identified in this sample. The remaining study sample (n = 188) served as the comparison group. Data on thrombosis, platelets, gestational age, birth weight, hematocrit, serum sodium, maternal preeclampsia, blood group, infant of diabetic mother (IDM) and demographic factors were collected using database and record review.ResultsAmong the total subjects (n = 210), 112 (53%) were males and 126 (60%) were Caucasians, with mean gestational age of 27.7 ± 2.1 weeks (standard deviation) and mean birth weight of 923 ± 195 g. Bivariate analysis revealed significant association of thrombosis with hematocrit >55% in the first week (odds ratio [OR] 5.4; 95% confidence interval [CI] 2.0–14.6; P = 0.0003), being small for gestational age (SGA) (OR, 2.9; 95% CI, 1.2–7.4; P = 0.02) and maternal preeclampsia (OR, 3.97; 95% CI, 1.6–9.84; P = 0.0017). In multivariate logistic regression analysis, only hematocrit >55% was independently associated with thrombus (OR, 3.7; 95% CI 1.1–11.8; P = 0.03).ConclusionsThis study demonstrates a significant, independent association between elevated hematocrit and development of UVC‐associated thrombosis. Careful monitoring for catheter‐associated thrombosis may be indicated in VLBW infants who have hematocrit >55% in the first week of life. Pediatr Blood Cancer 2009;52:75–79. © 2008 Wiley‐Liss, Inc.

Antenatal indomethacin can result in significant, prolonged RI in the infant. It may pose important risks to renal function and homeostasis in premature infants.
