Letter Randomized Controlled TrialPreemptive peritonsillar infiltration with lidocaine for relief of bipolar adult post-tonsillectomy pain: a randomized, double-blinded clinical study.
There are discordant results in the studies of the peritonsillar infiltration in adults undergoing the tonsillectomy. The study is to compare the effect of the preemptive peritonsillar infiltration with lidocaine in bipolar tonsillectomy in adult. 172 adult patients were randomly located into five groups before tonsillectomy: group 0: without the peritonsillar infiltration, group 1: for 3 ml normal saline with 1:200,000 epinephrine per tonsil, group 2: for 3 ml 1 %lidocaine with 1:200,000 epinephrine per tonsil, group 3: for 8 ml normal saline with 1:200,000 epinephrine per tonsil, group 4: for 8 ml lidocaine with 1:200,000 epinephrine per tonsil. The post-operative pain in the following 7 days was assessed by visual analog scale. ⋯ The differences between pain scores of the group 0, group 1 and group 2 were not statistically significant (P > 0.05). The differences between pain scores of group 3, group 4 against group 0, group 1, group 2 were statistically significant (P < 0.05). We found the volume of peritonsillar infiltration might contribute to the relief of pain of the bipolar post-tonsillectomy.

Randomized Controlled TrialDexamethasone contributes to the patient management after ambulatory laryngeal microsurgery by reducing sore throat.
This study was planned to evaluate the preventive effect of dexamethasone for sore throat after ambulatory laryngeal microsurgery. One hundred and ten patients scheduled for ambulatory laryngeal microsurgery under general anesthesia were randomly divided into two groups, group S1 and group D1. Patients in the group D1 were injected with 0.2 mg/kg of intravenous dexamethasone before the induction of anesthesia. ⋯ But at 6 h, the patients in the group D6 had lower incidence of sore throat than those in group S6 significantly (P = 0.003). Furthermore, the patients in the group D6 had lower severity of sore throat than those in group S6 significantly at 6 h (P = 0.001). In conclusion, prophylactic administration of intravenous dexamethasone is appeared to have efficacy for the management of sore throat in the early post-discharge period following ambulatory laryngeal microsurgery.
