![]() ![]() In our study, each anesthesia method was safely performed without any serious complications during or after operation, and there were no differences in the occurrence of nausea, vomiting, sore throat, and thirstiness, or in terms of patient satisfaction. Reasons for this are from differences in the operating surgeon, and in the type and method of the surgery. We believe this is because the closed reduction of the nasal bone performed in this study is a relatively non-invasive procedure, and the pain from the operation is not great. Precedent studies generally defined pain as being properly managed when the pain score is 30 mm or lower, and in our study, the mean pain score of both groups was well inside this range. In our study, the pain score of the MAC group measured in the recovery room was 28.84 mm showing no significant difference with the GA group (VAS = 24.66 mm) (P = 0.13). In addition, in other studies, the pain score of patients was significantly lower when dexmedetomidine was used compared to the general anesthesia group or the group with no anesthesia, and this confirms that dexmedetomidine has an analgesic effect. reported that there was a sufficient analgesic effect when dexmedetomidine was used for intraoperative anesthesia. When performing general anesthesia in elderly or in patients with underlying respiratory diseases, intubation and maintaining machine respiration could be factors that increase the occurrence of respiratory complications after operation. However, this study was performed on healthy ASA PS 1 and 2 patients with no underlying respiratory diseases. In the recovery room after the operation, there were no occurrences of reduced oxygen saturation or other respiratory complications, and this was the same in the GA group. oxygen saturation of 100% was accomplished, immediately. ![]() Six percent of the cases showed a SaO 2 reduction of 95% or lower, and when this occurred, deep breathing was performed around 4 times according to the orders of the anesthesiologist then an oxygen saturation of 100% was accomplished, immediately. In this study also, when the sedated state of BIS 60-80 was induced during the operation with dexmedetomidine, there was no occurrence of cases in which SaO 2 decreased to 90% or lower. In previous studies which performed sedation with dexmedetomidine, the sedative effect necessary for procedure was maintained while there was no occurrence of respiratory inhibition such as reduced oxygen saturation, increased end-tidal CO 2, or decrease in respiration rate to the end of the procedure. When performing local anesthesia after sedation, respiratory inhibition or inappropriate airway maintenance can occur during the operation because of the administration of sedatives or analgesics, and this could lead to intubation or general anesthesia. However, anxiety or pain felt by the patient can be problematic, so sedatives or analgesics are additionally used to minimize anxiety or pain. However, local anesthesia is advantageous in that intubation and mechanical ventilation is not necessary, there is less occurrence of sore throat or dry mouth after the operation, and changes in blood pressure from the anesthesia can be minimized. When using general anesthesia, there is the advantage that cooperation from the patient is unnecessary because the airway can be safely maintained along with complete loss of consciousness and analgesic effect. This operation can be performed under general or local anesthesia. However, nasal packing is performed after the operation and respiration is maintained only with the mouth thus, there could be difficulties in maintaining and managing the airway. Reduction of nasal bone fractures has a shorter operating time and less irritation compared to other operations. ![]()
