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.

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.

To determine whether continuous measurement of arterial oxyhemoglobin saturation (SpO2) and end-tidal carbon dioxide (P(ET)CO2) can be used to wean patients safely and efficiently from postoperative mechanical ventilation after cardiac surgery. ⋯ Continuous monitorin of SpO2 and P(ET)CO2 can be used to wean patients safely and effectively after CABG when adjustment of minute ventilation compensates for an increased PaCO2-P(ET)CO2 gradient during controlled ventilation.
