The Efficacy and Safety of Submandibular Transcatheter Perfusion Anesthesia in Submandibular Gland Surgery

摘要

The present study aims to evaluate the feasibility, safety, and effects of the combined use of submandibular transcatheter perfusion with lingual nerve block and subcutaneous infiltration for anesthetic purposes during submandibular gland surgery. A total of 38 patients with benign tumors, who had undergone resection by submandibular gland surgery were randomly divided into 2 groups. Patients in group A were administered with submandibular anesthesia through catheter perfusion, lingual nerve block, and subcutaneous infiltration anesthesia. Patients in the group B were only treated with lingual nerve block and subcutaneous infiltration anesthesia. The submandibular gland surgery was performed within 5minutes following anesthesia administration, after which the numerical rating scale (NRS) was evaluated before surgery, during skin incision (T-1), during the pulling process of the submandibular gland (T-2), during the removal of the submandibular gland (T-3), and at 2, 6, 12, and 24hours post-surgery. The dosage of analgesic drugs was also measured after surgery. The findings revealed no significant difference in NRS before surgery, at T-1, 6, 12, and 24hours after surgery (P>0.01) while NRS was much lower in group A patients as observed at T-2, T-3, and 2hours after surgery when compared with group B (P<0.01). The combined application of submandibular transcatheter perfusion with lingual nerve block and subcutaneous infiltration can be used as an effective anesthetic method during submandibular gland surgery.
