Our study is planned as a prospective, randomized, controlled, single blind. The details of the study are explained to the patients and their written informed consents are obtained.~Using the randomization program, the patients are divided into group 1 (acupuncture group) and group 2 (control group). Preoxygenation (100% oxygen with balloon and mask for 3 minutes) and midozolam 0.02 mg / kg and fentanyl 2 mcgr / kg are administered to both groups. In Group1, laser acupuncture is applied to each of the previously described P6, LI4 and LI 11 points on both arms with laser acupuncture device (Sedatelec Premio 32) for 30 seconds. In Group 2, same procedure is performed for 30 seconds while laser acupuncture closed. Then, propofol 2mg / kg is administered and a laryngeal mask is placed after 90 seconds in both groups. Maintenance anesthesia is provided with sevofurane and remifentanil infusion.
the aim of our study is to investigate if stimulation of the P6, LI4 and LI11 acupuncture points via laser acupuncture prevents sore throat caused by the classic laryngeal mask.
