Purpose: To investigate the differences in postoperative sore throat and hoarseness by adjustment of endotracheal tube cuff pressure (CP) during nitrous oxide ($N_2O$) and air anesthesia. Methods: A one-equivalent control group pretest-posttest design was used. Data were collected from August 8 to October 19, 2017 and analyzed using the independent t-test and repeated measures ANOVA. Eighty-four participants were enrolled and divided into three groups: 28 in the Control Group (CP adjusted every 30 minutes using $N_2O$), 28 in Experimental Group 1 (CP adjusted every 10 minutes using $N_2O$), and 28 in Experimental Group 2 (non-adjusted CP using air), all of whom underwent urologic, gynecologic, and orthopedic surgeries at the G University hospital. Sore throat was assessed using a numeric rating scale; hoarseness was evaluate using the Stout classification at 1, 6, and 24 hours after surgery. Results: Scores for sore throat and hoarseness were significantly different between the groups at each measurement time, and scores were consistently higher in the control group. During subsequent measurements, sore throat and hoarseness scores were significantly lower at 6 hours. Cuff pressure changed significantly using air anesthesia (${\chi}^2=10.41$, p=.015) up to 2 hours after induction. Severe sore throat and hoarseness was observed for up to 6 hours after surgery. Conclusion: Cuff pressure adjustment at short time intervals would be helpful in reducing postoperative sore throat and hoarseness. Nursing intervention focused on prevention of sore throat and hoarseness should be required up to 6 hours postoperatively in patients undergoing endotracheal intubation.

Purpose: The purpose of this study was to identify the effects of cuff pressure on postoperative sore throat. Methods: Data were collected from January 4 through May 15, 2008. Among the 60 patients, 30 patients were randomly assigned to the control group and the rest to the experimental group. Initial cuff pressure of both groups was set at 20 $cmH_2O$. The experimental group was maintained at 20 $cmH_2O$ throughout the anesthesia, while the control group was not regulated further. Sore throat was assessed at postoperative 1, 24 and 72 hours. Data were analyzed using Mann-Whitney test and Spearman's rho coefficients. Results: Cuff pressure in control group increased from 20 to 43 $cmH_2O$ within 3 hours after induction. However, the experimental group showed that there was apparently a reduced rate of sore throat at postoperative 24 hours (p = .048), and 72 hours (p = .002) than in the control group. However, no outstanding differences between both groups at postoperative 1 hour (p = .081) were detected. The correlation between cuff pressure and sore throat was statistically significant ($r_s$ = .590, p < .001). Conclusion: We conclude that maintaining cuff pressure at 20 $cmH_2O$ could be an effective means to reduce sore throat in surgical patients with inhalation anesthesia.

Purpose: This study aimed to identify the effect of warm scarf on xerostomia and sore throat in postoperative colon cancer patients. Methods: A total of 40 participants with colon cancer who underwent colon cancer operation over 2hours were included from C University hospital in Seoul. The number of experimental group and control group is each 20 calculated by G*Power, and they were assigned by using nonequivalent control group no-synchronized design. In the experimental group, a warm scarf was applied to the neck for 120 minutes from entering the recovery room after the colorectal cancer surgery was completed. In the experimental group and the control group, xerostomia and sore throat were measured twice at 60-minute intervals. The degree of xerostomia was measured through the degree of wetness of the absorbent paper in mm, and the degree of sore throat was measured through the NRS (Numeral Rating Scale). Data were collected using self-administered questionnaires from August 2018 to September 2020 and were analyzed using IBM SPSS/WIN 21.0 Descriptive statistics, x² test, Fisher's exact test, t-test were used to determine the participant's characteristics. The effect of warm scarf on xerostomia and sore throat were separately estimated by Repeated Measures ANOVA. Results: The experimental group showed significant decrease of xerostomia and sore throat as time goes (p<.001). Conclusion: Results indicate that warm scarf on xerostomia and sore throat in postoperative colon cancer patients is helpful method for relieving side effect of tracheal intubation.

Objective : Endotracheal tube cuff-pressure[ETCP] increases significantly during anterior cervical spine surgery with neck retraction. Clinically, postoperative hoarseness with sore throat is correlated with vocal cord edema due to longer intubation time and higher ETCP during neck retraction. Methods : Fifty patients of anterior cervical spine surgery were randomized to a control [no adjustment, 25 cases] and a treatment group [ETCP adjusted to 20mmHg, 25 cases]. Patients were blinded to their group assignments. They were questioned about the presence of ischemic symptoms [sore throat, dysphagia, hoarseness] postoperatively at different time points; 4 hours, 24 hours, and 1 week postoperatively. Results : No differences between groups at 4 hours and 1 week postoperatively were demonstrated. At 24 hours, 36% of patients in the treatment group complained of sore throat while 56% of control group patients did [p < 0.05]. Female patients correlated with development of all ischemic discomfort [p < 0.05 : sore throat, hoarseness, dysphagia]. Conclusion : Our results suggest that postoperative ischemic symptom following anterior cervical spine surgery may be associated with the two predictors; increased ETCP during neck retraction and female. The simple procedure of maintaining ETCP to 20mmHg can prevent postoperative tracheal ischemic symptom.

Purpose: The purpose of this study was to examine the effect of nebulizer therapy with normal saline on thirst and sore throat among postoperative patients. Methods: A quasi-experimental nonequivalent control group, pretest-posttest design was used with 50 participants. The experimental group received nebulizer therapy with normal saline every two hours for 10 minutes three times and wet gauze (n= 25), and the control group received only wet gauze (n= 25). Data were collected using the Numeral Rating Scale for Thirst and Sore Throat. Measurements were calculated before applying nebulizer therapy and total five times for 12 hours after treatment. Data were analyzed using the repeated measured ANOVA. Results: Thirst for the experimental group using the nebulizer therapy with normal saline improved more than for the control group (F= 3.06, p= .043). Sore throat was not significantly different between the two groups (F= 0.63, p= .565). Conclusion: Study results indicate that using nebulizer therapy with normal saline can reduced thirst for postoperative patients. So nurses can apply nebulizer therapy with normal saline to reduce thirst and to improve comfort for postoperative patients.

Purpose: A purpose of this study was to identify the effects of cold water gargling on thirst, oral cavity condition and sore throat in orthopedics surgery patients who underwent general anesthesia. Methods: Pretest-posttest non-synchronized design with a nonequivalent control group was used. A total of 52 participants were conveniently selected and assigned to each group. The experimental group gargled hourly with cold water for 8 hours after operation. The control group received wet gauze as needed. We compared the thirst, oral cavity condition and sore throat at 0, 2, 4 and 8 hours after operation. Results: The score of thirst and oral cavity condition was lower in the experimental group than in the control group. However, there was no significant differences in the levels of sore throat between the experimental and control group. Conclusion: These findings suggest that cold water gargling can be a useful nursing intervention for alleviating thirst and improving oral condition for patients with orthopedic surgery after general anesthesia.

Purpose: This study aimed to compare the effects of the Difflam spray 0.3% with the sodium bicarbonate-normal saline spray on oral care for postoperative patients. Methods: The participants were randomly allocated to either the Difflam (n=22) group or the saline solution (n=23) group. The data were collected at the 1-, 4-, 7-, and 10-hour marks after returning to the ward post operation using the Beck's subjective oral discomfort scale, Visual Analogue Scale for sore throat, and portable halitosis detector. Results: The sore throat (F=7.25, p=.001) score significantly decreased after oral care using the Difflam spray 0.3%. However, the difference in the scores of oral comfort (F=0.34, p=.797) and halitosis (F=0.91, p=.443) between the two groups was not statistically significant. Conclusion: These findings suggest that the Difflam spray 0.3% is effective in improving postoperative sore throat. A further study that explores the effect of various oral solutions for postoperative patients is needed to present systemic and effective evidence-based oral care guidelines.

Background : After sinus surgery, airway dryness is made worse because patients breathe by mouth. Anticholinergic agents have antisialogogue effects. The airway dryness that occurs after surgery is severe and can increase the incidence of postoperative sore throat. Materials and Methods : One-hundered patients who were scheduled for endoscopic sinus surgery(ESS) were divided into four groups. Each group was premedicated with glycopyrrolate or had no premedication and reversed with glycopyrrolate or atropine. After the surgery the patients were asked about a sore throat and hoarseness postoperatively after 1h, 6h, 12h, 24h, and 48hours, respectively. Results : The incidence of postoperative sore throat and hoarseness was not significantly different among the four groups at any time. Conclusion : The severity of complications after ESS was low and subsided within 24 hours. Therefore, the use of anticholinergic agents does not need to be limited.
