Randomized Controlled Trial Clinical TrialEffect of preoperative dexamethasone on edema of oral and extra-oral structures following trans-oral decompression and posterior fusion.
We investigated the anti-edema effect of intravenous dexamethasone in a randomized, double-blinded, placebo-controlled study in 40 ASA physical status I and II patients scheduled for trans-oral decompression and posterior fusion. Patients were divided into two groups to receive either placebo or 10 mg dexamethasone one hour prior to induction of anesthesia. After anesthesia induction, oral structures were graded as swelling grade 0 at direct laryngoscopy. ⋯ Patients with swelling grades of 1 and 2 were extubated on each assessment. On statistical analysis of the results, the study found that in comparison to placebo, patients in the dexamethasone group were extubated earlier (P < 0.006, Chi Square for trend). Total duration of surgery and duration of posterior fusion were significantly greater (P < 0.05) in patients who had swelling grade >2 than in patients who had swelling grade < or =2 at completion of surgery (192.50 +/- 16.26, 356.07 +/- 17.06 minutes versus. 158.27 +/- 9.07, 311.41 +/- 14.06 minutes).
