Randomized Controlled TrialComparison of clonidine, local anesthetics, and placebo for pain reduction in pediatric tonsillectomy.
To determine if pretonsillectomy injection of local anesthetics with and without clonidine reduces pain following tonsillectomy in children. ⋯ Pretonsillectomy injection of lidocaine, 1%, and bupivacaine, 0.5%, with or without clonidine (25 μg) is not recommended for the reduction of posttonsillectomy pain.

Randomized Controlled Trial Comparative StudyUse of laryngeal mask airway in pediatric adenotonsillectomy.
To compare the use of flexible laryngeal mask airway (LMA) and endotracheal tube (ETT) in pediatric adenotonsillectomy. ⋯ An LMA is an efficient alternative to ETT in pediatric adenotonsillectomy. When comparing LMA and ETT, there is no difference in rates of laryngospasm. Time to extubation is significantly shorter in patients using LMA. Before adopting the routine use of LMA in pediatric adenotonsillectomy, further study is needed to address visualization and kinking issues associated with this device.

Randomized Controlled TrialInformed consent in pediatric surgery: Do parents understand the risks?
To investigate parent understanding of the risks of pediatric ear, nose, and throat surgery after counseling with and without the use of informational aids. ⋯ Parents of children undergoing ear, nose, and throat surgery recall far less than 100% of counseled risks. The use of detailed surgical risk counseling improves measured parental understanding of surgical risk. Parental educational level and maternal vs paternal parent may affect risk counseling recall.

Randomized Controlled TrialThe hemostatic and hemodynamic effects of epinephrine during endoscopic sinus surgery: a randomized clinical trial.
To assess the hemodynamic and hemostatic effects of 2 different concentrations of epinephrine in local anesthetic used during functional endoscopic sinus surgery (FESS). Injection of local anesthetic containing epinephrine during endoscopic sinus surgery, while providing hemostasis, has been associated with cardiac adverse effects such as tachycardia, hypertension, as well as arrhythmias. ⋯ Submucosal injection of lidocaine, 2%, with 1:200 000 epinephrine during FESS does not lead to hemodynamic fluctuations or increased intraoperative bleeding compared with lidocaine, 2%, with 1:100 000 epinephrine.
