Randomized Controlled Trial Clinical Trial
Effect of preanesthetic intramuscular ranitidine on gastric acidity and volume in children.
To evaluate the effects of preanesthetic administration of intramuscular (IM) ranitidine on pH and volume of gastric contents in children. ⋯ Preanesthetic IM ranitidine 1 to 2 mg/kg resulted in a higher pH and lower volume of gastric fluid at the time of induction and in a higher pH during 3 hours of anesthesia. This therapy may be a useful adjunct to premedication for children who have a greater than normal risk of pulmonary aspiration during anesthesia.

The Bullard laryngoscope is a rigid fiber-optic device that offers a new approach to oral laryngoscopy. In this report, I present five cases illustrative of the use of the Bullard laryngoscope in patients with demonstrated or suspected difficult laryngoscopy and intubation.

Review Case Reports
Anesthetic management of obstructive sleep apnea patients.
Presented in an illustrative case report and a review of the anesthetic management of obstructive sleep apnea patients. Preoperative evaluation should include a thorough airway evaluation and a comprehensive cardiovascular and pulmonary evaluation. With polysomnography, identification of the severity of sleep apnea can be idenified. ⋯ Opioids and sedatives should be avoided, as should other drugs that have central and sedating effects. Postoperative pain is effectively controlled with acetaminophen and topical anesthetic sprays. Postoperative monitoring for apnea, desaturation, and dysrhythmias is a necessity in sleep apnea patients.
