To compare a new, clear, unmarked polyvinylchloride (PVC) tracheal tube marketed for use during Neodymium-Yttrium-Aluminum-Garnet (Nd-YAG) laser surgery with a conventional marked PVC tracheal tube. ⋯ The clear, unmarked Sheridan PVC tracheal tube is not recommended for laser airway surgery.

Case Reports
Application of the Mizus endotracheal obturator in tracheostomy and tentative extubation.
A variety of catheters, stylets, and obturators have been used to assist with problems in airway management. Obturators specifically designed for airway use are now available in different sizes. ⋯ Use of these obturators to preserve a path to the airway is described in cases of tracheostomy and tentative extubation. The advantages and disadvantages inherent in the use of such obturators are described.

To determine whether a single epidural dose of morphine sulfate is effective in providing 12- to 24-hour pain relief in children. ⋯ Single-dose caudal epidural morphine in children is safe and effective when administered intraoperatively prior to surgery as the only opioid and coupled with appropriate monitoring, nursing education, and follow-up by the anesthesiologist. These patients can be followed on regular nursing floors with proper monitoring.

To estimate the magnitude behavior of ferrous-alloy, wire-reinforced microcatheters for subarachnoid anesthesia and the possible hazards of exposing patients to magnetic resonance imaging (MRI) after accidental catheter fracture within the subarachnoid space. ⋯ The microcatheters under test exhibited marked magnetic properties. Two questions arise: First, should MRI be avoided in patients where broken TFX catheter fragments may lie partly or completely within the subarachnoid space? Second, should ferrous metallic strengthening wire be replaced by a nonmetallic fiber of comparable or greater tensile strength? Further in vitro studies are indicated to answer these questions.
