YouTube as an Information Resource for Persons Interested in Septoplasty and/or Turbinoplasty

Background and Objectives@#YouTube is a widely used web site. In general, many people search for medical information on YouTube. We evaluated the septoplasty and turbinoplasty videos on YouTube from an expert’s point of view. @*Methods@#We used “septoplasty,” “turbinoplasty,” and “septoplasty turbinoplasty” to search YouTube. Of the 150 videos, we eventually viewed 83. Two researchers assessed the sources, lengths, and numbers of likes, dislikes, and views. The videos were classified as “excellent,” “moderate,” or “poor” in terms of utility; we also evaluated the uploaded material and content. @*Results@#Of the 83 videos, 18 (21.7%) were excellent, 27 (32.5%) were moderate, and 38 (45.8%) were poor. We found no significant differences in length and mean likes, dislikes, and views between the groups classified as useful. Fifteen (39.5%) of 38 poor videos were by patients, and 13 (34.2%) of 38 poor videos were by physicians. When organized by content type, videos on personal experiences were significantly longer than the others. Of 20 videos on personal experiences, 15 (75%) were poor and all 5 advertisement videos (100%) were poor. @*Conclusion@#Information from YouTube on septoplasty and turbinoplasty is not yet adequate. However, since YouTube content cannot be controlled, it is necessary to upload objective and accurate videos for patients and experts in professional groups such as the medical society. Such videos should be promoted and used actively.

Adverse events of sugammadex that occurred in a Korean population

With increasing use, the incidence of adverse events associated with sugammadex, a neuromuscular blockade reverser, is increasing. This study aimed to identify and analyze cases of adverse events caused by sugammadex reported in Korean population. Methods: Out of a total of 12 cases detected using various keywords in the Korean Journal of Anesthesia, Anesthesia and Pain Medicine (Seoul), KoreaMed, PubMed, EMBASE, Web of Science, and The Cochrane Library-CENTRAL from 2013 to December 2020, 10 cases directly associated with sugammadex were selected. Results: Adverse events included five cases of anaphylaxis, one case of cardiac arrest, one case of profound bradycardia, one case of negative pressure pulmonary edema, and two cases of incomplete recovery. Three patients had American Society of Anesthesiologists physical status ≥ 3, two had emergency surgery, and two had a history of allergic reaction. Neuromuscular monitoring was applied in nine cases. The average dose of sugammadex was 2.87 mg/kg, and there were six cases in which one full vial was used, regardless of the state of neuromuscular recovery. Sugammadex was administered immediately after surgery in two cases, at train of four (TOF) 0 in four cases, at TOF 3 in one case, and after evaluation of the clinical signs only with no neuromuscular monitoring in one case. Conclusions: Even with neuromuscular monitoring, an excessive dose of sugammadex was observed. Given that adverse events tend to occur within 10 min of administration, continuous monitoring is important even after administration.

Cochlear Implantation after Subtotal Petrosectomy in Patients with Chronic Otitis Media / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: This study investigated the surgical and rehabilitative results of cochlear implantation combined with subtotal petrosectomy in patients with chronic otitis media. SUBJECTS AND METHOD: We retrospectively reviewed the medical records of nine adult patients (7 men and 2 woman; mean age 58.9 years), who were operated between 2004 and 2014. Out of the nine, seven patients received simultaneous cochlear implantation and subtotal petrosectomy and two patients were operated by stage depending on the condition of the middle ear. All cases underwent closure of the external auditory canal and Eustachian tube, and the obliteration of mastoid cavity using abdominal fat. Surgical outcomes and performance of the patients after cochlear implantation were analyzed. RESULTS: Middle ear inflammation was completely managed with this surgical technique. No patients showed postoperative symptoms related to otitis media after the surgery. Cochlear implant was successfully replaced and active electrodes were fully inserted in all of the cases. There were no immediate complications including abscess, infection, meningitis, cerebrospinal fluid leakage and ear canal problem. One patient was observed with delayed extrusion of the ball electrode, which was replaced with cartilage reinforcement under local anesthesia. Patient performance, measured in terms of speech evaluation and quality of life during the medical interview, were successful and satisfactory. CONCLUSION: Cochlear implantation with subtotal petrosectomy seems to be very safe and effective for patients deafened by chronic otitis media. Long term follow-ups for possible extrusion of the electrode or other complications are still necessary.

Effects of Nitrous Oxide and Desflurane on Cardiovascular Responses to Endotracheal Intubation / 대한마취과학회지

BACKGROUND: Endotracheal intubation often results in hypertension and tachycardia. Desflurane and nitrous oxide (N2O) are known to augment the sympathetic nervous activity. We examined whether N2O and desflurane affect the cardiovascular responses to the intubation. METHODS: One hundred-fifty patients were assigned randomly to receive one of six treatment regimens (n = 25 each): 2% sevoflurane (control), 6% desflurane or 12% desflurane with and without 75% N2O, respectively. General anesthesia was induced with intravenous thiopental (5-7 mg/kg), and tracheal intubation was facilitated with intravenous vecuronium (0.12 mg/kg). N2O was started 3 min before and desflurane soon after the intubation. Systolic arterial blood pressure (SAP), heart rate (HR), and plasma catecholamine concentrations were determined. RESULTS: The intubation increased SAP and HR in all groups within 1 min. A second increase was noted with 12% desflurane at 3 to 5 min after the intubation. N2O did not affect the tachycardiac response, but attenuated the pressor response to both intubation and 12% desflurane. The plasma concentrations of norepinephrine increased significantly at 1 min after the intubation in all groups with more pronounced rise in N2O groups, and increased further at 5 min in the 12% desflurane groups. CONCLUSIONS: A biphasic increase of SAP and HR was noted with 12% desflurane. The first increase may be related with the mechanical stimulus of the tracheal intubation and the second with the desflurane itself. Although N2O did not affect the tachycardiac responses and augmented norepinephrine release, it suppressed the pressor responses.
