Despite the widespread move to premedication for neonatal intubation, many deficiencies in everyday practice remain. The rate of haemodynamic complications is high in this commonly used premedication regimen. This study shows that there are important factors to control at the local level in terms of timely preparation and administration of premedication drugs, training and supervision of staff carrying out this high-risk procedure.

SummaryThe decision to transfuse a neonate can be approached by addressing a series of questions that cover the cause of anaemia, alternatives to transfusion, the need for transfusion and the risks. Recent clinical trials of red cell transfusions have started to inform evidence-based transfusion practice, but have raised uncertainties about neurological outcomes when policies advocating use of fewer red cell transfusions at lower haemoglobin concentration (Hb) thresholds were tested. Red cell transfusions should be considered when the Hb <120 g/l for premature neonates requiring mechanical ventilation support, with lower thresholds applying for oxygen-dependent neonates not requiring ventilation or for late anaemia (Hb <70-100 g/l, depending on gestational and post-natal age). There is no recent high quality evidence to inform thresholds for prophylactic platelet transfusions in stable non-bleeding premature neonates with platelet count levels of 50 9 10 9 /l, although common practice has become more restrictive, using lower safe thresholds for platelet transfusion between 20 and 30 9 10 9 /l. A more appropriate transfusion strategy for fresh frozen plasma (FFP) in neonates is one that emphasizes the therapeutic use of FFP in the face of bleeding, rather than prophylactic use in stable non-bleeding neonates who often have mild to moderate apparent abnormalities of standard coagulation tests, after allowing for appropriate reference ranges.

SummaryPremature neonates commonly receive red blood cell (RBC) transfusions. This study systematically identified and appraised randomized controlled trials (RCTs) where the intervention was 'transfusion of red blood cells' from searches of multiple databases. Primary review outcomes were mortality, neurodevelopmental and respiratory endpoints. Two reviewers extracted data and assigned overall quality. Twenty-seven RCTs were identified and grouped into four predefined categories: trials comparing RBC transfusion versus no transfusion/placebo (n = 3); different thresholds for transfusion (n = 6); differing doses or administration schedule (n = 4), or different types or products of RBC (n = 14). In the threshold group of trials, enrolling 679 neonates, no significant differences in mortality (relative risk 1·22, 95% confidence interval 0·84-1·75) or chronic lung disease were found. Only two trials assessed neurodevelopment outcomes, both within the threshold group, but with differing results. The largest subgroup of RCTs by number evaluated different media for storage of red cells (n = 7), enrolling 221 neonates. The methodological quality of many RCTs was poor. The design of future RCTs can be informed by the lessons from this review. Many trials failed to report on outcomes that would be considered of primary importance to clinicians. Consistent reporting of adverse events is required, and endpoints need to include neurodevelopmental outcomes.

The majority of neonates with ST bleed, although most episodes are minor. These findings establish the importance of clinical factors for bleeding risk, rather than minimum platelet count. Further studies should assess the clinical significance of different types of minor bleed for neonatal outcomes, the predictive value of minor bleeding for major bleeding and the role of platelet transfusions in preventing bleeding.
