UVC tip localisation by standard radiography is very imprecise, and catheter tip migration occurs in a significant proportion of infants during first weeks of age. We suggest ultrasound as the best modality to assist localisation and follow-up of UVC tip in preterm infants.
The available evidence does not support the routine use of inhaled nitric oxide (iNO) in the care of premature infants. We present a case series of 22 preterm infants born after prolonged preterm premature rupture of membranes and oligohydramnios with respiratory failure. Oxygenation index decreased significantly after commencement of iNO.
Our data suggests that NO may play a key role in the pathogenesis of IUGR. We also, for the first time, provide information on umbilical arterial MetHb levels in PE, normotensive IUGR and normotensive AGA pregnancies.
AimNoise levels above 45 dB in a neonatal intensive care unit (NICU) and 60 dB during neonatal transport are recognised hazards, but protective equipment is not standard. We measured noise levels in both settings, with and without noise protection.MethodsPeak sound and equivalent continuous sound levels were measured in a NICU and during road transport, at a mannequin's ear and inside and outside the incubator. Recordings were made without protective earwear, with noise protecting earmuffs and with active noise cancelling headphones.ResultsIn the NICU, the peak levels at the ear, and inside and outside the incubator, were 61, 68 and 76 dB. The equivalent continuous sound levels were 45, 54 and 59 dB. During road transport, the respective levels were 70, 77 and 83 dB and 54, 62 and 68 dB. In the NICU, 80% of environmental peak noise reached the ear and this was reduced to 78% with earmuffs and 75% with active noise cancelling. The respective figures during transport were 87% without protection and 72% with active noise cancelling, with an unexpected increase for ear muffs.ConclusionNoise levels exceeded safe limits in the NICU and during transport, but active noise cancelling reduced exposure.
Multi-disciplinary collaborative care for pregnant women with complex and emergent conditions is essential. Logistical planning, clear communication and human factor awareness are all non-clinical skills which need to be utilised in order to maximise outcomes. We describe the case of a proximal aortic dissection in the late third trimester of pregnancy diagnosed in a peripheral hospital that was transferred to a cardiothoracic centre for successful operative management 160 km away. This required the time-sensitive mobilisation and liaison of a receiving cardiothoracic, anaesthesiology and perfusionist team in conjunction with obstetric and midwifery support from an affiliated maternity hospital, as well as the national neonatal transport team. We emphasise the importance of multidisciplinary team management in complex cases and how imperative good inter-disciplinary communication is to ensure safe inter-hospital transfer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
