Randomized Controlled Trial Clinical TrialPrevention of silent aspiration due to leaks around cuffs of endotracheal tubes.
Significant aspiration may occur around correctly inflated high volume, low pressure endotracheal tube cuffs. The prevention of silent aspiration due to leaks around cuffs of endotracheal tubes was investigated during general anesthesia for hip replacement in 47 patients. The patients were randomly assigned to one of three groups, in which one of three endotracheal tubes of different designs were used for intubation. ⋯ At termination of the operation, the trachea below the cuff was inspected with a fiberoptic bronchoscope. Aspiration was found in 12.5% with the Rüsch tube, in 31.2% with the Mallinckrodt tube, and in 0% with the NL tube. Our results show that silent aspiration is still a problem with standard endotracheal tubes, but that it may be minimized by use of appropriate tubes, cuffs, and control of cuff inflation.

Randomized Controlled Trial Comparative Study Clinical Trial
Esophageal gastric tube airway vs endotracheal tube in prehospital cardiopulmonary arrest.
We evaluated the efficacy of the esophageal airway (EA) by prospectively randomizing 175 prehospital cardiopulmonary arrest patients to receive either an esophageal gastric tube airway (EGTA) or an endotracheal tube (ET). If attempts with the initial airway failed, the alternate airway was attempted. The cost of training paramedics in EA use was considerably less than the ET ($80 vs $1,000). ⋯ The incidence of neurologic residual (ET 50 percent, EGTA 36.4 percent) and congestive heart failure (ET 40 percent, EGTA 45.5 percent) in surviving ET and EGTA patients did not differ (NS). An additional 125 consecutive patients with only the opportunity to receive an EA were also evaluated and did not differ in mortality, neurologic residual, or congestive heart failure from ET patients. We conclude that the EA is a satisfactory alternative to the ET for short-term prehospital use in cardiopulmonary arrest patients.

Three cases of trismus caused by oropharyngeal sepsis are described where fibreoptic-assisted awake intubation using an oral airway intubator and nebulised lidocaine was safely and successfully achieved.
