Case Reports
Management of a suspected and unsuspected difficult laryngoscopy with the laryngeal mask airway.
The laryngeal mask airway (LMA) is a new development in airway control. Presented here are two cases of difficult airway management--one anticipated, the other not anticipated--during which the LMA was used effectively.

Comparative Study
Frequency and severity of desaturation events during general anesthesia in children with and without upper respiratory infections.
To determine whether anesthesia in the presence of a mild upper respiratory infection (URI) was associated with episodes of desaturation or reactive airway problems. ⋯ Children with a mild URI have an increased frequency of minor desaturation episodes, and intubated patients with a URI have an increased frequency of bronchospasm. It appears that children with a mild URI may be safely anesthetized, since the problems encountered are generally easily treated and without long-term sequelae.

Randomized Controlled Trial Clinical Trial
Early anesthesia evaluation of the ambulatory surgical patient: does it really help?
To evaluate whether early evaluation by the anesthesiologist is more beneficial for the ambulatory surgical patient than a day-of-surgery visit. ⋯ Healthy ASA physical status I and II ambulatory surgical patients do not benefit from reducing preoperative anxiety by visiting the anesthesiologist prior to the day of surgery.

Amniotic fluid embolism (AFE) is a rare obstetric problem characterized by sudden onset of hypotension, hypoxemia, and coagulopathy. This case represents the difficulty in differentiating AFE from other etiologies of cardiopulmonary compromise. The definitive diagnosis of AFE is made at autopsy with the demonstration of fetal cell elements in the pulmonary vasculature. ⋯ Predisposing factors for AFE include advanced maternal age, multiparity, large fetal size, and short tumultuous labor, especially if uterine stimulants are used. Cardiopulmonary resuscitation is the key to the treatment of parturients with AFE. A pulmonary artery catheter can be helpful in diagnosis and hemodynamic management of parturients with AFE.

The perioperative management and dissemination of critical information regarding a patient with an unexpected difficult intubation, including successful application of a difficult airway algorithm (Figure 1), are described. Documentation and dissemination of critical information include entry of patient data into an in-hospital computerized Difficult Airway/Intubation Registry, simultaneous application of a highly visible Difficult Airway/Intubation Patient Wrist Band (coded for access to computer registry), summary reports distributed to health care providers, and enrollment of the patient in the Medic Alert Foundation International's newly established category difficult airway/intubation for 24-hour access. We postulate that the widespread use of the procedures described in this report may reduce the contribution of unexpected difficult airway/intubation to anesthetic morbidity and mortality.
