Objective: To determine the prevalence of and to classify ultrasound-proven brain injury during neonatal extracorporeal membrane oxygenation in The Netherlands., Design: Retrospective nationwide study (Rotterdam and Nijmegen), spanning two decades., Setting: Level III university hospitals., Subjects: All neonates who underwent neonatal extracorporeal membrane oxygenation from 1989 to 2010., Interventions: None., Measurements and Main Results: Cranial ultrasound images were reviewed independently by two investigators without knowledge of primary diagnosis, outcome, type of extracorporeal membrane oxygenation, or statistics. The scans were reviewed for lesion type and timing, with the use of a refined classification method for focal brain injury. Extracorporeal membrane oxygenation type was venoarterial in 88%. Brain abnormalities were detected in 17.3%: primary hemorrhage was most frequent (8.8%). Stroke was identified in 5% of the total group, with a notable significant preference for the left hemisphere (in 70%). Lobar hematoma (prevalence 2.2 %) was also significantly left predominant., Conclusion: The incidence of brain injury found with cranial ultrasound in The Netherlands of the patients treated with extracorporeal membrane oxygenation during the neonatal period was 17.3%. Primary hemorrhage was the largest group of lesions, not clearly side-specific except for lobar bleeding, most probably related to changes in venous flow. Arterial ischemic stroke occurred predominant in the left hemisphere.

Aim: To determine the effects of propofol for endotracheal intubation in neonates in daily clinical practice., Methods: We prospectively studied the pharmacodynamic effects of intravenous propofol administration in neonates who needed endotracheal intubation at the neonatal intensive care unit., Results: Propofol was used for 62 intubations in neonates with postmenstrual ages ranging from 24 + 3 weeks to 44 + 5 weeks and bodyweights ranging from 520 to 4380 g. A 2 mg/kg bodyweight propofol starting dose was sufficient in 37% of patients; additional propofol was needed less often on the first postnatal day. The mean amount of propofol used was 3.3 (±1.2) mg/kg. The success rate of intubation depended on the experience of the physician and was related to the total administered amount of propofol. Hypotension occurred in 39% of patients and occurred more often at the first postnatal day. In 15% of procedures, propofol mono therapy was insufficient., Conclusion: This study shows that high doses of propofol are needed to reach effective sedation in neonates for intubation, with hypotension as a side effect in a considerable percentage of patients. Further research in newborn patients needs to identify optimal propofol doses and risk factors for hypotension., (©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.)

Background: Since 2010, the European Resuscitation Council (ERC) guidelines advise oxygen saturation (SpO2) targets for the first 10 min of resuscitation after birth. Unfortunately, the control of SpO2 in newborn infants is difficult., Aim: To determine to what extent SpO2 levels match the ERC targets during the resuscitation of very preterm infants, and how well the SpO2 is kept within the high and low limits until the infants are transported to the NICU., Methods: In a single-centre observational study, the SpO2 and fraction of inspired oxygen (FiO2) were collected during the resuscitation of very preterm infants with a gestational age (GA)≤ 30 weeks., Results: A total of 78 infants were included [median (IQR): GA 27(4)/7 (26-28(6)/7) weeks, birth weight 945 g (780-1140)]. During the initial 10 min after birth, large variations in SpO2 were observed with deviations above the target [median (IQR)] of 4.4% SpO2 (1.4-6.5), and below the target of 8.2% SpO2 (2.8-16.0). After the first 10 min, the SpO2 levels were respectively above and below the limit for 11% (0-27) and 8% (0-23) of the time., Conclusion: During the resuscitation of very preterm infants, large deviations of the SpO2 from the ERC targets are observed. During the first minutes of resuscitation the deviations were likely caused by an inability to control the SpO2, whereas later deviations were due to weaning, pauses in respiratory support (i.e. intubation) and over exposure to oxygen. Changing the SpO2 targets to a target range that depicts the acceptable deviation might be helpful in providing better respiratory support., (Copyright © 2013 Elsevier Ireland Ltd.

Background: Neonatal intubation is a stressful procedure that requires premedication to improve intubation conditions and reduce stress and adverse physiological responses. Premedication used during the INSURE (INtubation, SURfactant therapy, Extubation) procedure should have a very short duration of action with restoration of spontaneous breathing within a few minutes., Aims: To determine the best sedative for intubation during the INSURE procedure by systematic review of the literature., Methods: We reviewed all relevant studies reporting on premedication, distress, and time to restoration of spontaneous breathing during the INSURE procedure., Results: This review included 12 studies: two relatively small studies explicitly evaluated the effect of premedication (propofol and remifentanil) during the INSURE procedure, both showing good intubation conditions and an average extubation time of about 20 minutes. Ten studies reporting on fentanyl or morphine provided insufficient information about these items., Conclusions: Too little is known in the literature to draw a solid conclusion on which premedication could be best used during the INSURE procedure. Both remifentanil and propofol are suitable candidates but dose-finding studies to detect effective nontoxic doses in newborns with different gestational ages are necessary.

Background: A large single-center randomized trial showed that treating hyperglycemia in critically ill children improved outcome, despite an increased incidence of hypoglycemia, especially in infants., Objectives: We evaluated the efficacy and incidence of hypoglycemia using a tight glucose protocol in critically ill term neonates., Methods: Term hyperglycemic (>8 mmol·l(-1); >144 mg·dl(-1)) neonates treated with a tight glucose protocol during a 3.5-year period in a tertiary pediatric intensive care unit were retrospectively analyzed., Results: Seventy-three term hyperglycemic neonates [age 0 days (0-6), weight 3.2 ± 0.8 kg, PRISM 16 (11-20)] were included for analysis. Eighteen neonates died (25%). The initial mean (range) glucose level was 11.1 mmol·l(-1) [9.6-15.2; 200 mg·dl(-1) (173-274)], and normoglycemia (<8 mmol·l(-1); <144 mg·dl(-1)) was reached within 5.3 h (1-25) with an overall treatment duration of 27 h (10-57). Seven hypoglycemic incidents (5 times ≤2.2 mmol·l(-1); 40 mg·dl(-1), and 2 times <1.7 mmol·l(-1); 31 mg·dl(-1)) occurred in 5 (6.7%) infants, without severe clinical signs. Three hypoglycemic incidents were directly explained due to a protocol violation. One hypoglycemic incident occurred with the onset of sepsis, while no apparent cause was identified for three hypoglycemic incidents., Conclusions: Our glucose protocol was effective, but hypoglycemia occurred more frequently than in older children reported previously. Potential differences in glucose and insulin metabolism in term neonates appear to justify additional safety approaches, while awaiting further studies assessing the benefits of tight glucose protocols in this population. Meanwhile, we have decreased the initial insulin starting doses in our protocol., (Copyright © 2011 S. Karger AG, Basel.)
