Randomized Controlled Trial Comparative StudyEffects of midazolam/low-dose ketamine conscious intravenous sedation on pain, swelling, and trismus after surgical extraction of third molars.
To assess the clinical efficacy of midazolam plus low-dose ketamine conscious intravenous sedation on relief from or prevention of postoperative pain, swelling, and trismus after the surgical extraction of third molars. ⋯ Conscious intravenous sedation with midazolam/low-dose ketamine during surgical extraction of third molars can provide the patient with a comfortable procedure and good postoperative analgesia, with less swelling and significantly less trismus. Intravenous low-dose ketamine may be safe and effective in reducing postoperative pain.

Comparative StudyOptimal degree of mouth opening for laryngeal mask airway function during oral surgery.
This study was performed to determine the optimal degree of mouth opening in anesthetized patients requiring laryngeal mask airway (LMA) during oral surgery. ⋯ This study showed that a mouth opening over 4 cm led to substantial increases in oropharyngeal leak pressure and intracuff pressure of the LMA, warranting caution, because gastric insufflation, sore throat, and ventilation difficulties may occur. A mouth opening of 3 cm achieves acceptable airway conditions for anesthetized patients requiring LMA.
