Randomized Controlled Trial Clinical Trial
The prevention of postoperative stridor and laryngospasm with topical lidocaine.
Tonsillectomy and adenoidectomy can predispose to stridor and laryngospasm in the immediate postextubation period. A prospectively randomized study of 133 patients undergoing tonsillectomy and adenoidectomy was undertaken to determine if the topical application of 4 mg/kg of 4% lidocaine at the time of intubation would decrease the incidence of postoperative stridor and laryngospasm. Taken together, eight (12%) of 67 control patients suffered stridor or laryngospasm vs two (3%) of 66 patients receiving lidocaine. ⋯ This can present a challenge to even the most adept otolaryngologist and anesthesiologist. Accidental extubation is always possible, and reintubation can be difficult in the presence of blood and saliva. The difficulty is often compounded with a patient who is not completely paralyzed.

Rapid intraoperative tissue expansion (RITE) has been shown to have definite applicability to reconstruction in the head and neck. However, widespread use of this modality has yet to be adopted by the otolaryngologic community. ⋯ Eight patients were selected and underwent reconstruction using a total of 10 tissue expanders. Herein, we describe our experience with this initial series as well as some background and future applications of RITE.

Randomized Controlled Trial Clinical Trial
The effect of steroid therapy on recovery from tonsillectomy in children.
A prospective, randomized, double-blind study to determine the postoperative effects of steroids in tonsillectomy was performed on 25 children from 4 to 12 years of age. A single intravenous dose of dexamethasone or a placebo was administered at onset of surgery. Other preoperative and postoperative medications, including antibiotics, anesthesia, and surgical techniques were standardized as noted in this article. ⋯ By the fifth and sixth days, the control group were eating as well as those children who received steroids. No significant differences were observed in postoperative pain, nausea, emesis, fever, or in the need for postoperative pain medications. This preliminary article concludes that a single preoperative dose of steroid results in an earlier return to a normal (full) diet in children who had undergone tonsillectomy.

The effectiveness of local anesthetics is improved by the addition of a vasoconstrictor with an increased duration of action and the ability to decrease both systemic toxic reactions and local bleeding. Epinephrine, the standard drug for vasoconstriction, has some limitations due to potential cardiac and local toxic effects. Using an animal model, we compared the effects of various concentrations of epinephrine and two other vasoconstrictors, phenylephrine hydrochloride and felypressin, on local blood flow. ⋯ We found that felypressin was as effective a vasoconstrictor as epinephrine, with fewer potential toxic reactions. Phenylephrine (Neo-Synephrine), on the other hand, was less effective, with a shorter duration of action. As expected, bupivacaine produced vasodilation, while ropivacaine was found to have vasoconstrictive properties.
