We present a patient with sudden cardiovascular collapse during cesarean delivery that was attributed to amniotic fluid embolism (AFE). The syndrome of AFE may be initiated by an anaphylactoid response to amniotic fluid in the maternal circulation that triggers the release of pulmonary vasoconstrictors, with transient pulmonary vasospasm, causing hemodynamic collapse and profound left ventricular failure. Milrinone, a pulmonary vasodilator used in the management of emergent right ventricular failure, was administered via a nebulizer in an effort to decrease pulmonary vascular resistance.

Methods: Utilizing parental and provider feedback, a protocol including environment modification, anxiolysis plans, specialized order sets, and child life specialist (CLS) support was developed over a nine-month period.
Background: Ambulatory surgery plays an important role in pediatric anesthesia. However, it is difficult to predict which patients will experience complications. Age >80, ASA class 3 or 4, duration of surgery >3 h, and BMI 30-35 are independent predictors of unanticipated admission in adults.

Methods: A random sample of 200 patients requiring admission (cases) and 200 patients not requiring admission (controls) was taken from 20,657 ambulatory procedures was identified and compared. The following variables were included: demographics, reason for admission, type of anesthesia, surgical procedure, length of procedure, American Society of Anesthesiologists' (ASA) classification, surgical completion time, pre-anesthesia clinic, medical history, medications (classes), and perioperative complications.
Aims: To evaluate a more effective method of identifying children with familial hypercholesterolaemia by screening a population at high risk.
Methods: Domiciliary measurement of random cholesterol concentration was made in 200 children who were first or second degree relatives of subjects with premature onset coronary artery disease. Measurements were taken by a health visitor using a portable analyser.
