The present study summarizes the knowledge to date of the use of remifentanil in obstetric anaesthesia and analgesia. ⋯ Remifentanil has a place in obstetric anaesthesia and analgesia. Further studies are needed to confirm if background infusions are safe in addition to patient-controlled analgesia. Studies are needed to establish a dose range under general anaesthesia that prevents neonatal respiratory depression at birth.

Improvement in anesthesia outcomes has derived from advances in safety science related to equipment, drugs, human factors analysis, professional standardization and organization, subspecialty care, and regionalization. Outcomes of pediatric anesthesia have improved, but universal outcome measures are lacking. Because of the limitations of small numbers, future improvement efforts will necessarily involve multiple disciplines, institutions, and regions, and will require sophisticated systems approaches.

ReviewEmergence agitation in pediatric anesthesia: current features.
Postoperative agitation in children is a well-documented clinical phenomenon with incidence ranging from 10% to 67%. There is no definitive explanation for this agitation. Possible causes include rapid awakening in unfamiliar settings, pain (wounds, sore throat, bladder distension, etc.), stress during induction, hypoxemia, airway obstruction, noisy environment, anesthesia duration, child's personality, premedication and type of anesthesia. The purpose of this paper is to discuss the possible causes of postoperative agitation in children, providing a foundation for better methods of identifying and preventing this problem. ⋯ No single factor can identified as the cause of postoperative agitation, which should therefore be considered a syndrome made up of biological, pharmacological, psychological and social components, and which anesthesiologists and pediatric intensive care specialists should be prepared to identify, prevent and intervene appropriately as necessary.

ReviewAnesthetic management of children with pulmonary arterial hypertension.
Pulmonary arterial hypertension (PAH) is associated with significant perioperative risk for major complications, including pulmonary hypertensive crisis and cardiac arrest. Several mechanisms of hemodynamic deterioration, including acute increases in pulmonary vascular resistance (PVR), alterations of ventricular contractility and function and coronary hypoperfusion can contribute to morbidity. ⋯ The development of specific pulmonary vasodilators has led to significant advances in medical therapy of PAH that can be incorporated in anesthetic management. It is important that anesthesiologists caring for children with PAH be aware of the increased risk, understand the pathophysiology of PAH, form an appropriate anesthetic management plan and be prepared to treat a pulmonary hypertensive crisis.

Neuromuscular blockade monitoring aims should be based on effectiveness criteria, that is, to administer the lowest effective dose, and on security criteria, avoiding overdosage and detecting possible residual blockade before patient extubation. A neuromuscular blockade monitoring and usage protocol should be available with predefined objectives for each patient to achieve the minimum effective doses. Maintenance of a light blockade level probably influences the decrease in complications associated with these drugs' use. ⋯ Ensuring adequate sedation and analgesia in a paralysed patient is essential. An inadequately sedated but paralysed patient may subsequently suffer serious psychological and emotional stress. Bispectral index monitoring with sedative doses adjusted to 40-60 values assures, in most situations, correct sedation.
