A rescue airway device is used when conventional methods of intubation fail to achieve control of the airway. Although the laryngeal mask airway is often used in the operating room should endotracheal intubation fail, the esophageal-tracheal double-lumen airway represents another alternative rescue airway device. ⋯ The most commonly used esophageal-tracheal double-lumen airway device is the Combitube (TYCO Healthcare, Pleasanton, Calif), which will be used to illustrate insertion techniques needed in the use of esophageal-tracheal double-lumen airways. Nurse anesthetists should familiarize themselves with the function and placement of the device in case it is needed.

Cyclodextrins are molecules with a hollow, truncated cone shape that possess unique lipophilic and hydrophilic properties. These unique properties enable cyclodextrins to engulf and bind lipophilic molecules while maintaining aqueous solubility. ⋯ Sugammadex is the name of a modified cyclodextrin currently in phase 3 studies by Organon International (Oss, The Netherlands), and it may hold promise for a new concept in muscle relaxant reversal. Encapsulation rather than competitive antagonism of neuromuscular blockade may be a future modality of anesthetic practice.

Preoperative cardiac assessment has become an integral part of contemporary anesthesia practice. Simple clinical markers can identify high-risk patients, but the question of how to reduce cardiac complications among high-risk patients has been controversial. Good quality randomized controlled trials have showed that neither preoperative coronary revascularization nor the placement of pulmonary artery catheters reduces perioperative cardiac complications. ⋯ The data supporting these conclusions are reviewed in an evidence-based manner. At present, it is prudent to treat moderate- to high-risk patients undergoing elective surgery with beta-blockers if possible. Because not all patients are candidates for beta-blocker therapy, data regarding the perioperative use of alternative medications to reduce perioperative cardiac complications have been explored and are reviewed.

Review Case Reports
Unintended subdural injection: a complication of epidural anesthesia--a case report.
Epidural anesthesia is practiced in virtually every clinical setting. Its safety and versatility have supported increasing use for more and varied therapies. In a healthy patient in whom near-complete left hemiparesis developed following a routine continuous epidural anesthetic for labor, subdural deposit of the local anesthetic was suspected. The following case and discussion may help illustrate the mechanism behind this complication and how it can be detected, treated, and, possibly, avoided.

The popularity of regional anesthesia blocks for both intraoperative anesthesia and postoperative pain management supports the inclusion of the administration of regional anesthesia into discussions about operating room (OR) efficiency. This article reviews the literature on OR efficiency with a focus on day-of-surgery decision making. ⋯ Regional anesthetic block placement can affect surgical schedules, and thus OR efficiency. When patient safety is unaffected, rearranging OR schedules on the day of surgery to place regional blocks, meet surgeon requests, or move up incision times should generally not be done if doing so results in otherwise unnecessary increases in overutilized OR time.
