Randomized Controlled Trial Comparative Study Clinical Trial
The gum elastic bougie eases tracheal intubation while applying cricoid pressure compared to a stylet.
To compare the ease of tracheal intubation facilitated by the gum elastic bougie or the malleable stylet while applying cricoid pressure. ⋯ Applying cricoid pressure worsened laryngeal view. The use of a gum elastic bougie was more effective than the use of a stylet to facilitate intubation.

To examine the hypothesis that pain treatment with patient controlled analgesia (PCA) using iv morphine is a suitable and safe alternative to epidural analgesia in morbidly obese patients undergoing gastric bypass surgery. We retrospectively compared the postoperative periods in all patients undergoing this procedure in our institution between November 1999 and November 2001. ⋯ We conclude that in grossly obese patients undergoing gastric bypass surgery PCA with iv morphine is an acceptable strategy for pain management and may confer some advantages when compared to epidural analgesia.

To examine the delivery rates of four disposable, non-electric infusion pumps during hypobaric conditions. ⋯ The infusion rates of disposable infusion pumps are reduced under hypobaric conditions. Even though we still do not know how the epidural pressure changes under hypobaric conditions, clinicians should be aware that the infusion rate of disposable infusion pumps is decreased under hypobaric conditions.

Case Reports
Airway management in a patient with a cleft palate after pharyngoplasty: a case report.
To describe a practical method of aiding nasotracheal intubation in a cleft palate patient with previous pharyngoplasty using a suction catheter under tactile guidance. Problems of airway management in these patients are also discussed. ⋯ Preoperative determination of the type of pharyngoplasty is essential to understand the anatomy of the patent velopharyngeal port. A history of pharyngeal flap infection, hyponasal voice or upper airway obstruction suggests possible port stenosis. We describe a tactile guided technique that is useful and practical. Use of a flexible suction catheter of small external diameter minimizes the potential for trauma, bleeding and creation of false passages.
