ReviewIntraoperative hypotension in neonates: when and how should we intervene?
Organ hypoperfusion remains an important cause of postoperative morbidity in neonates. Blood pressure (BP) is frequently mistakenly used as a surrogate of organ perfusion and the predictive value of BP for outcome is unclear. The current article will focus on the role of BP in the optimization of organ perfusion during anaesthesia in neonates. ⋯ Anaesthetic management should focus on optimizing organ perfusion and not merely on maintaining a particular BP. A collaborative approach is recommended. The carbon dioxide tension is crucial to perfusion in the presence of cardiovascular shunts.

The aim of this review is to discuss recent developments in vascular access technology and to highlight those that are particularly relevant to the practitioner. ⋯ Despite the development of new technical devices, successful venous puncture remains heavily dependent on the skills of the operator.

ReviewAnesthesiological considerations for children with obstructive sleep apnea.
To summarize recent evidence-based data regarding outcomes associated with children who have obstructive sleep apnea (OSA). ⋯ Perioperative deaths in children with OSA occur at a low frequency. Hypoxia-induced opioid sensitivity combined with an approximate 1-2% incidence of rapid conversion of codeine to morphine suggest the need for new approaches for providing preoperative assessment of risk, extended postoperative observation and the need for alternative opioids to codeine. Additionally, new less painful surgical approaches may help to reduce postoperative opioid requirements and therefore perhaps less risk for opiate-induced apnea in this vulnerable population.

ReviewBlood conservation strategies and the management of perioperative anaemia.
Anaemia is a global health problem with particularly high prevalence in the perioperative setting and it can significantly affect the patient outcomes. This review addresses new findings on the significance of anaemia and patient blood management (PBM) strategies to prevent and manage anaemia. ⋯ Despite the high prevalence of anaemia and the significant toll it takes on patients, simple and effective strategies are available to detect, diagnose and treat it.

ReviewAspirin in the perioperative period: a review of the recent literature.
The indications for aspirin (ASA) for both primary and secondary prevention of thrombotic events continue to evolve. We review some of these indications and the recent literature regarding the perioperative administration of ASA. ⋯ The continuation or discontinuation of ASA perioperatively remains a complicated issue. Further, well designed trials are needed for additional clarification.
