OBJECTIVE: To evaluate the effectiveness of intermittent 10 U/mL heparin flushes in reducing the occlusion of peripherally inserted central catheters in neonates. METHODS: In this randomized, open-label, prospective, controlled study, neonates were allocated either to receive 0.5 mL flushes of heparin (Group 1: n = 64) or saline (Group 2: n = 69) every 4 hours. Actions were taken to restore patency by using negative pressure (3-way stopcock method) in cases of occlusion. RESULTS: A total of 133 neonates were included. No significant intergroup difference was observed in the number of new occlusions (26 in Group 1, or 31/1,000 catheter-days; 36 in Group 2, or 36/1,000 catheter-days; P = 0.19). In Group 1, 5 catheters had 9 recurrent obstructions after successful clearance maneuvers. In Group 2, 19 catheters had 40 relapses (P < 0.0001), showing heparin's protective role against recurrence of obstruction (Relative Risk = 0.36). However, heparin failed to prevent catheter withdrawal due to permanent occlusion (3 catheters in Group 1 and 8 in Group 2; P = 0.24). CONCLUSION: Intermittent heparin is not effective for preventing the occlusion of peripherally inserted central catheters in neonates but reduces relapses when clearance maneuvers were successful

OBJECTIVES: To evaluate risks for persistent pulmonary hypertension in the newborn, confirmed by echocardiography, associated with cesarean deliveries and other factors. METHODS: Cohort of all deliveries >36 weeks within a period of 23 months. A nested case-control study was performed in a subset of the cohort, involving newborns admitted into neonatal intensive care unit with diagnosis of persistent pulmonary hypertension matched with normal controls, with application of questionnaires to mothers to identify risks. Logistic regression was used to calculate odds ratios. RESULTS: From 9452 newborns, 8388 (88.7%) were delivered by cesarean and 1064 (11.3%) by vaginal delivery. Questionnaires were applied to 173 mothers. Infants from cesareans had a fivefold increased risk of persistent pulmonary hypertension of the newborn: 42 (0.5%) versus 1 case (0.09%) in the vaginal group (OR 5.32, p=0.027). No interactions were found between smoking, parity, arterial hypertension and labor before cesarean section and persistent pulmonary hypertension of the newborn. First minute Apgar score <7 and maternal diabetes were related to increased risk. CONCLUSION: Reducing cesarean deliveries could prevent many cases of serious persistent pulmonary hypertension of the newborn.
