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.

ReviewMaternal critical care: 'one small step for woman, one giant leap for womankind'.
The purpose of this study is to outline the challenges of looking after women who either become or are at a risk of becoming critically ill during pregnancy. ⋯ In this review, we identify the need for maternal critical care, explore different models of its provision and outline possible benefits and barriers to its future implementation.

The expected difficult airway in children is a rare, but predictable entity, which can lead to life-threatening situations, when sufficient oxygenation and ventilation cannot be achieved. This review gives an overview on current techniques and recommendations on where, who, when, and how to treat children with expected difficult airway. ⋯ The expected difficult airway in children is predictable by clinical signs and medical history in most of the cases and therefore anticipative. It should always be managed in specialized centers. In emergency situations, optimized face mask ventilation (aided by an oropharyngeal/nasopharyngeal airway) or ventilation via supraglottic airway devices or a nasopharyngeal tube can be most helpful skills until definitive airway management is available. These emergency techniques should be taught regularly in all anesthesia departments where children present for elective and nonelective surgery.

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.

Recent literature on the role of transthoracic echocardiography in the management of women with preeclampsia is reviewed with emphasis on recommendations for its use in the life-threatening complications of acute pulmonary edema, chest pain, and hemorrhage. ⋯ The role of transthoracic echocardiography in the management of women with preeclampsia is emphasized by international groups. Research into the hemodynamics in preeclampsia, which demonstrates preserved ejection fraction, and diastolic dysfunction highlights its utility and acceptability by pregnant women with preeclampsia. Training of obstetric anesthesiologists in echocardiography is necessary to enable more widespread implementation of this important technology.
