Randomized Controlled Trial Clinical Trial
Intubating laryngeal mask for fibreoptic intubation--particularly useful during neck stabilization.
To assess the ease of fibrescope-assisted tracheal intubation while the patient's head and neck were placed in the neutral or the manual in-line position, and to determine if the intubating laryngeal mask facilitated fibreoptic intubation in these positions. ⋯ Fibreoptic tracheal intubation was more difficult in the manual in-line position than in the neutral position. The intubating laryngeal mask facilitated fibreoptic intubation in both positions.

To report an unusual case of pulmonary edema following intramuscular ketamine administration. ⋯ Ketamine was given im to aid burns dressing in this case because it has distinct advantages above the other anesthetic agents including that of being a good analgesic which is absorbed by im route. Its use led to the development of pulmonary edema.

We describe pharyngeal oximetry with the laryngeal mask airway in two patients with low perfusion states where finger oximetry failed. ⋯ Pharyngeal oximetry with the laryngeal mask airway is feasible in low perfusion states when finger oximetry fails.

Most Canadian University Departments of Anesthesia require residents to take the American Board of Anesthesiology-American Society of Anesthesiologists (ABA-ASA) in-training examination (ITE). The result is expressed as a percentile relative to all examinees at similar levels of training. Its value as a predictor of performance in the Royal College of Physicians and Surgeons of Canada (RCPSC) certification examinations is not known. ⋯ The ABA-ASA ITE is a useful tool in predicting performance on the RCPSC examination.

Clinical Trial
Free hemoglobin concentrations in patients receiving massive blood transfusion during emergency surgery for trauma.
To determine free hemoglobin concentration in patients who received massive blood transfusion during emergency surgery for trauma with consideration of the storage of the transfused blood. ⋯ After blood transfusion during surgery for trauma, serum haptoglobin concentration decreased with transfusion of > or = 1,000 mL of whole blood with mean storage time of 12.2 dy. Free hemoglobin was detected after 2,000 mL transfusion when THp decreased to 1,000 mgxL(-1). Serum haptoglobin concentrations correlated negatively with storage time (days) of transfused blood.
