Effect of a combination of 2% lidocaine jelly and thermally softened endotracheal tube on postoperative sore throat

BACKGROUND: Postoperative sore throat (POST) is a common adverse event after general anesthesia. The aim of this study was to evaluate the effectiveness of 2% lidocaine jelly applied on the single-lumen endotracheal tube (ETT) and thermal softening of the ETT, and a combination of both interventions on the development of POST. METHODS: Patients (n = 144) undergoing general anesthesia were randomly assigned to one of four groups: Control group (un-softened ETT lubricated with saline); Lidocaine group (un-softened ETT lubricated with 2% lidocaine jelly); Softened group (thermally softened ETT lubricated with saline); and Combined group (thermally softened ETT lubricated with 2% lidocaine jelly). Sore throat was evaluated at 0, 1, 6, 24, and 48 h after extubation. The occurrence of any postoperative complication was also assessed including hoarseness and coughing. RESULTS: No significant difference was observed in the severity of POST at all time points. However, the incidences of POST for overall (0–48 h) and the immediately following period (0 h) were significantly lower in the Combined group (52.9% and 47.1%) than in the Control group (79.4% and 76.5%), Lidocaine group (81.8% and 78.8%), and Softened group (82.9% and 74.3%). The overall incidence of hoarseness did not differ among the groups. No other postoperative complication was observed in any of the patients. CONCLUSIONS: No differences were observed in the severity of POST. However, 2% lidocaine jelly applied on thermally softened ETT reduced the overall incidence of POST. Therefore, this combined intervention could be considered as an alleviating strategy for POST.

Patterns of Emergency Department Use During the Korean Doctor's Strike

PURPOSE: From June 20, 2000, to June 24, 2000, for five nationwide hospitals and clinics went on strike in opposition to the government 's policy on the separation of dispensaries from medical practice. The present study examined the present state of medical examination and treatment and the management system of the third medical institution to indicate a model for dealing with such strikes ahead in the future. METHODS: The present state of the medical examination and management system in eight hospitals of the nationwide emergency medical centers was examined. The term of strike, June 20, 2000, to June 24, 2000, for five days, was the subject term; Five weekdays of the week just prior to the strikes and two consecutive holidays, January 1, 2000, and January 2, 2000, were chosen as a contrast group. RESULTS: During the term of strike, the number of patients was larger than it was on the weekdays, but was less than it was on consecutive-holidays. In severity triage, the ratio of emergency patients increased but non-emergency and delayed patients decreased than consecutive-holidays, and the number of medical personnel decreased for all types of visits. The attending hospitals in cases of disease increased, and the ratio of internal medicine, general surgery, obstetrics, orthopedics patients increased than consecutive-holidays level, and the ratio of gynecology, phychiatry, opthalmology patients increased than consecutive-holidays and weekdays level. The ratio of cases in CPR decreased, and deliveries was at the same level as it was on the weekdays. Both radiation tests and emergency tests decreased. CONCLUSION: During a strike, carrying out severity triage and operating emergency outpatient care for non-emergency patients, such as outpatients, may be desirable. Adding emergency-treatment manpower to the areas where the number of patients increased, putting additional nursing and assistance manpower in emergency and operation rooms, providing for administration manning at the consecutive-holidays level, and resetting radiation and examination manpower at the consecutive-holidays level should be considered in managing effectively and emergency medical center.
