Effects of preoperative inhaled budesonide combined with intravenous dexamethasone on postoperative sore throat in patients who underwent thyroidectomy: A randomized controlled trial.

BACKGROUND: This randomized controlled trial aimed to evaluate the efficacy of preoperative inhaled budesonide combined with intravenous dexamethasone on postoperative sore throat (POST) after general anesthesia in patients who underwent thyroidectomy. METHODS: Patients who underwent elective thyroidectomy were randomly divided into the intravenous dexamethasone group (group A) and budesonide inhalation combined with intravenous dexamethasone group (group B). All patients underwent general anesthesia. The incidence and severity of POST, hoarseness, and cough at 1, 6, 12, and 24 hours after surgery were evaluated and compared between the 2 groups. RESULTS: There were 48 and 49 patients in groups A and B, respectively. The incidence of POST was significantly lower at 6, 12, and 24 hours in group B than that in group A (P < .05). In addition, group B had a significantly lower incidence of coughing at 24 hours (P = .047). Compared with group A, the severity of POST was significantly lower at 6 (P = .027), 12 (P = .004), and 24 (P = .005) hours at rest, and at 6 (P = .002), 12 (P = .038), and 24 (P = .015) hours during swallowing in group B. The incidence and severity of hoarseness were comparable at each time-point between the 2 groups (P > .05). CONCLUSION: Preoperative inhaled budesonide combined with intravenous dexamethasone reduced the incidence and severity of POST at 6, 12, and 24 hours after extubation compared with intravenous dexamethasone alone in patients who underwent thyroidectomy. Additionally, this combination decreased the incidence of postoperative coughing at 24 hours.

Effect of intravenous and topical laryngeal lidocaine on sore throat after extubation: a prospective randomized controlled study.

OBJECTIVE: The present study aimed to compare the effect of topical laryngeal lidocaine with intravenous lidocaine before endotracheal intubation on the incidence and severity of postoperative sore throat, hoarseness, and cough. PATIENTS AND METHODS: This prospective randomized controlled study enrolled 144 patients undergoing laparoscopic cholecystectomy with endotracheal intubation. The patients were randomized to three groups and received 2% lidocaine by topical laryngeal spray (group T), intravenous 2% lidocaine (group I), and the equivalent volume of intravenous saline (group C) before intubation. The incidence and severity of sore throat, hoarseness, and cough reaction at 0.5, 1, 6, and 24 h after extubation were collected. RESULTS: The incidence of sore throat was significantly lower in group T than in groups I and C (6.4% vs. 37.2% and 86.7%, p < 0.001), respectively at 0.5 h after extubation, and it was significantly lower in group I than that in group C (37.2% vs. 86.7%, p < 0.001). Both the incidence of hoarseness and cough were significantly lower in group T than in group I and in group C (14.9% vs. 97.7% and 97.8%, p < 0.001, and 19.1% vs. 72.0% and 93.3%, p < 0.001), respectively. The severity of sore throat, hoarseness and cough in group T was significantly lower than that in group I and that in group C (p < 0.05), and it was significantly lower in group I than in group C (p < 0.05). CONCLUSIONS: Both topical laryngeal lidocaine and intravenous lidocaine before intubation have positive effects on preventing sore throat. Topical laryngeal route was superior to intravenous route.

A Plasmacytoma of the Lateral Pharyngeal Wall: A Diagnostic Enigma.

Plasmacytoma is a rare plasma cell dyscrasia that grows in bones or soft tissues such as the pharynx. Soft tissue plasmacytomas are rare, and a higher burden has been reported in the upper aero-digestive tract, often manifesting as hoarseness, dysphagia, or odynophagia. Due to their rarity, extramedullary plasmacytomas (EMPs) have unknown prognostic factors, and guidelines for optimal management are still lacking. However, radiation therapy and surgery have been used with positive outcomes. Herein, we describe a unique case of plasmacytoma of the pharyngeal tissue in a male patient with a history of HIV disease. The patient completed 28 sessions of radiation therapy, resulting in an improvement in his throat pain and hoarseness. Given the patient's age and lack of traditional risk factors for head and neck cancers, his hoarseness and odynophagia proved to be a diagnostic conundrum. Although infrequent, soft tissue plasmacytomas should be considered in the differential diagnosis of head and neck tumors.

Extramedullary plasmacytoma of the larynx - Case report.

Extramedullary plasmacytoma of the larynx is an extremely rare entity accounting for 0.04-0.45% of malignant tumours of the larynx. The objective of this clinical case report is to highlight the diagnosis and management of a unique case such as this. A 77-year-old gentleman presented with complaints of hoarseness for 1 year. Computed tomography image revealed a soft tissue mass lesion involving the right true vocal cord. Direct laryngoscopic biopsy was performed and subjected to histopathological examination, which showed collection of plasma cells. Immunohistochemistry confirmed the presence of Kappa and Lambda cells. Multiple myeloma (MM) was ruled out. The patient received radical intent radiation therapy using 3DCRT technique with a dose of 50Gy in 25# over 5 weeks. He experienced improvement in hoarseness on subsequent follow-up visits. At 1-year follow up, positron emission tomography computed tomography showed near total resolution of disease with no progression to MM. Radiation therapy alone is known to achieve good local control, recurrence free survival, and organ preservation in such cases.

Flurbiprofen in the subglottic space to prevent postoperative sore throat after cardiac surgery: A randomized double-blind study.

STUDY OBJECTIVE: Postoperative sore throat (POST) and hoarseness are common complications of tracheal intubation. This study aims to evaluate the efficacy of flurbiprofen administered through the subglottic port of tracheal tubes to prevent POST after cardiac surgery. DESIGN: Single-center, prospective, randomized, double-blind, placebo-controlled trial. SETTING: Tertiary Care Referral University Hospital (Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome). PATIENTS: Included 71 patients undergoing for elective cardiac surgery. Inclusion criteria were (a) age between 50 and 75 years, (b) NYHA class I or II, (c) surgery for myocardial revascularization or valve repair or replacement under cardiopulmonary bypass. INTERVENTION: Patients were double blind randomized to receive flurbiprofen or saline in the subglottic port of the endotracheal tube (groups F and P). The solution was injected ten minutes after tracheal tube placement, ten minutes after ICU admission and ten minutes before tracheal tube removal. MEASUREMENTS: The primary outcome was to assess the effect of topical flurbiprofen administered through the subglottic port of the tracheal tube to prevent post-operative sore throat (POST). The secondary outcomes were the presence of hoarseness safety and patient's subjective satisfaction with their recovery. We did not report any exploratory outcomes. MAIN RESULTS: We analyzed 68 patients, 34 patients in each group. In group F, two patients complained of POST and hoarseness (5.9%), while all controls did. The two groups significantly differed in the severity scores (VAS and TPS for sore throat and HOAR for hoarseness) at all time points. In group P, patients reported mild to moderate symptoms that significantly improved or disappeared 36 h after tracheal tube removal. According to the multivariable model, hoarseness affected women less than men, in the control group (p = 0.002). None of the patients in either group reported any adverse effects. CONCLUSIONS: Repeated administration of flurbiprofen through the subglottic port of tracheal tubes reduced the incidence of sore throat and hoarseness after cardiac surgery without evidence of complications.

The effect of different endotracheal tube cuff pressure monitoring systems on postoperative sore throat in patients undergoing tracheal intubation: a randomized clinical trial.

BACKGROUND: Postoperative sore throat (POST) is an unpleasant outcome that can occur as a result of tracheal intubation in adults. Increased pressure from the endotracheal tube (ETT) cuff often leads to local mucosal injury, resulting in sore throat. The purpose of this study was to compare the effect of two different ETT cuff pressure monitoring systems vs. no cuff pressure monitoring on the incidence and severity of POST in adults. METHODS: One hundred and fourteen ASA I-III patients of either gender, aged 18-65 years, and undergoing surgery requiring endotracheal intubation were included in this study. Patients were randomized into three groups: control (C), cuff pressure gauge (G), and automated cuff controller (A). The ETT cuff pressure was not monitored intraoperatively in group C but was monitored using a cuff pressure gauge and an automated cuff controller in groups G and A, respectively. Postoperatively, patients were assessed at 2, 24, and 48 h for the presence and severity of POST, hoarseness and cough. RESULTS: One hundred and eleven patients completed the study. POST occurred in 40.5% of the patients in group G (n = 37) (p = 0.013) and 23.7% of the patients in group A (n = 38) (p < 0.001) within 48 h after surgery, compared to 69.4% in group C (n = 36). There were no significant differences in hoarseness, coughing, and dysphagia across the groups at any time. When comparing groups A and C, individuals in group A exhibited a lower occurrence of significant (grade ≥ 2) POST and hoarseness (10.5% vs. 41.7%, p = 0.002; 26.3% vs. 58.3%, p = 0.005). The incidence of significant cough and dysphagia did not differ substantially across the patient groups within 48 h after surgery. POST scores in group A at 2, 24 h postoperatively were both 0 (0-0), which was significantly lower than those in group C (1 (0-2) at 2 h, p < 0.001 ; 1 (0-1) at 24 h, p = 0.001). POST in group G at 2 h postoperatively was graded as 0 (0-1.5) which was milder than group C (P = 0.024). The severity of hoarseness in group A with scores of 0 (0-2) was superior to that in group C (2 (0-2), p = 0.006) at 2 h postoperatively. CONCLUSIONS: In conclusion, the findings of this study indicated that the occurrence of POST can be reduced by using either the cuff pressure gauge approach or the automated cuff controller method. The automated cuff controller monitoring can potentially decrease the severity of POST and hoarseness.

Ease of endotracheal intubation with the conventional polyvinyl chloride endotracheal tube versus wire-reinforced flexometallic tube through the intubating laryngeal mask airway: A comparative study.

Background The I-LMA ventilates while providing a port for blind insertion of an endotracheal tube. The ILMA Fastrach is used especially for intubating in a difficult airway scenario. Its accompanying endotracheal tube is not economical nor readily available. In comparison, two alternative endotracheal tubes - polyvinyl chloride and wire-reinforced tubes were used for tracheal intubation through the ILMA. AIMS AND OBJECTIVES: The aim of our study was to compare the ease of intubation when using conventional PVC tubes versus the wire-reinforced flexometallic tubes with the ILMA-FastrachTM. The number of attempts, time taken and additional maneuvers were noted. Intra-operative hemodynamic changes, post-operative sore throat, bleeding and hoarseness of voice was recorded over a period of 24 hours. METHODOLOGY: After informed consent, 60 ASA I-II patients undergoing elective surgeries under general anesthesia were allocated to undergo blind intubation with the PVC tube or the wire-reinforced flexometallic tube. RESULTS: More attempts were required for successful intubation using the wire-reinforced tube than the PVC tube with 76.7% passing in the first attempt in the PVC, and 53.3% passing in the first attempt in the flexometallic group. (P = 0.4). Average time for intubation in the PVC group: 28.24 ± 7.22 seconds. Average time for intubation in the flexometallic tube: 45.8 ± 15.78 sec. Occurrence of post-operative sore throat was 13.3% in the PVC group and 26.6% in the flexometallic group, with minimal hoarseness of voice 3.3% in the PVC group and 10% in the flexometallic group. There was also a slightly higher hemodynamic response in those who were intubated with the flexometallic tube than a PVC tube. CONCLUSION: Intubating via the ILMA-Fastrach with the PVC tube offered better intubating conditions with regards to lesser time taken, lesser attempts, less manipulation, and less hemodynamic variations as compared to the patients who were intubated using the wire-reinforced tube.

Résumé Arrière-plan: L'I-LMA ventile tout en fournissant un port pour l'insertion aveugle d'une sonde endotrachéale. L'ILMA Fastrach est utilisé notamment pour l'intubation dans un scénario de voies respiratoires difficiles. La sonde endotrachéale qui l'accompagne n'est ni économique ni facilement disponible. En comparaison, deux tubes endotrachéaux alternatifs ­ du chlorure de polyvinyle et des tubes renforcés de fil ­ ont été utilisés pour l'intubation trachéale via l'ILMA. Buts et objectifs: Le but de notre étude était de comparer la facilité d'intubation lors de l'utilisation de tubes en PVC conventionnels par rapport aux tubes flexométalliques renforcés de fil avec l'ILMA-FastrachTM. Le nombre de tentatives, le temps nécessaire et les manÓuvres supplémentaires ont été notés. Les changements hémodynamiques peropératoires, les maux de gorge postopératoires, les saignements et l'enrouement de la voix ont été enregistrés sur une période de 24 heures. Méthodologie: Après consentement éclairé, 60 patients ASA I-II subissant des interventions chirurgicales électives sous anesthésie générale ont été affectés à une intubation aveugle avec le tube en PVC ou le tube flexométallique renforcé de fil. Résultats: Plus de tentatives ont été nécessaires pour réussir l'intubation à l'aide du tube renforcé par fil métallique qu'avec le tube PVC, avec 76,7 % de réussite lors de la première tentative dans le groupe PVC et 53,3 % de réussite lors de la première tentative dans le groupe flexométallique. (P = 0,4). Temps moyen d'intubation dans le groupe PVC : 28,24 ± 7,22 secondes. Temps moyen d'intubation dans le tube flexométallique : 45,8 ± 15,78 sec. La survenue de maux de gorge postopératoires était de 13,3 % dans le groupe PVC et de 26,6 % dans le groupe flexométallique, avec un enrouement minime de la voix de 3,3 % dans le groupe PVC et de 10 % dans le groupe flexométallique. Il y avait également une réponse hémodynamique légèrement plus élevée chez ceux qui étaient intubés avec le tube flexométallique qu'avec un tube en PVC. Conclusion: L'intubation via l'ILMA-Fastrach avec le tube en PVC offrait de meilleures conditions d'intubation en ce qui concerne moins de temps, moins de tentatives, moins de manipulations et moins de variations hémodynamiques par rapport aux patients intubés à l'aide du tube renforcé de fil Mots-clés: Facilité d'intubation, sonde endotrachéale flexométallique, masque laryngé d'intubation des voies respiratoires, sonde endotrachéale en polychlorure de vinyle.

The effects of video double-lumen tubes on intubation complications in patients undergoing thoracic surgery: A randomised controlled study.

BACKGROUND: Tracheal injuries, vocal cord injuries, sore throat and hoarseness are common complications of double-lumen tube (DLT) intubation. OBJECTIVE: This study aimed to evaluate the effects of 'video double-lumen tubes' (VDLTs) on intubation complications in patients undergoing thoracic surgery. DESIGN: A randomised controlled study. SETTINGT: Xuzhou Cancer Hospital, Xuzhou, China, from January 2023 to June 2023. PATIENTS: One hundred eighty-two patients undergoing elective thoracic surgery with one-lung ventilation were randomised into two groups: 90 in the DLT group and 92 in the VDLT group. INTERVENTION: VDLT was selected for intubation in the VDLT group, and DLT was selected for intubation in the DLT group. A fibreoptic bronchoscope (FOB) was used to record tracheal and vocal cord injuries. MAIN OUTCOME MEASURES: The primary outcomes were the incidence of moderate-to-severe tracheal injury and the incidence of vocal cord injury. The secondary outcomes included the incidence and severity of postoperative 24 and 48 h sore throat and hoarseness. RESULTS: The incidence of moderate-to-severe tracheal injury was 32/90 (35.6%) in the DLT group, and 45/92 (48.9%) in the VDLT group ( P  = 0.077; relative risk 1.38, 95% CI, 0.97 to 1.95). The incidence of vocal cord injury was 31/90 (34.4%) and 34/92 (37%) in the DLT and VDLT groups, respectively ( P  = 0.449). The incidence of postoperative 24 h sore throat and hoarseness was significantly higher in the VDLT group than in the DLT group (for sore throat: P  = 0.032, relative risk 1.63, 95% CI, 1.03 to 2.57; for hoarseness: P  = 0.018, relative risk 1.48, 95% CI, 1.06 to 2.06). CONCLUSION: There was no statistically significant difference in the incidence of moderate-to-severe tracheal injury and vocal cord injury between DLTs and VDLTs. While improving the first-attempt success rate, intubation with VDLT increased the incidence of postoperative 24 h sore throat and hoarseness.

Squamous Cell Carcinoma of the Supraglottis Presenting as Hoarseness.

Hoarseness is a well-known condition in primary care offices, with over 1% of primary care visits secondary to this ailment.1 The most common causes are acute laryngitis (40%), functional dysphonia (30%), benign and malignant tumors (2.2 to 30%), neurogenic factors such as vocal cord paralysis (8%), physiological aging (2%), and psychogenic factors (2.2%). Most of these cases are secondary to viral infections and do not require antibiotics on most occasions. These viral infections subside after 1 to 2 weeks, and in the case of persistent hoarseness (above 4 weeks) the American Academy of Otolaryngology recommends direct visualization with a laryngoscopy before treatment with proton pump inhibitors, antibiotics, or steroids. Our patient presented with prolonged hoarseness (greater than eight weeks) but had a quick turn around time interval between primary care visit and laryngoscopy evaluation (less than 2 weeks). This led to her diagnosis and treatment with chemo and radiation therapy within three months of diagnosis with Squamous Cell Carcinoma of the Supraglottis. The Primary care physician serves as the number one point of visitation by sufferers of hoarseness. It is important that they are knowledgeable and up to date with recommendations and guidelines for managing this condition, as unwarranted delay can affect overall outcome on the part of the patient. This is especially important in patients such as ours with high risk factors including Nicotine dependence, alcohol use, asbestos exposure, and HPV infection.

La voix rauque est une condition bien connue dans les cabinets de soins primaires, avec plus de 1 % des visites en soins primaires dues à ce problème. Les causes les plus courantes sont la laryngite aiguë (40%), la dysphonie fonctionnelle (30 %), les tumeurs bénignes et malignes (2,2 à 30 %), les facteurs neurogènes tels que la paralysie des cordes vocales (8 %), le vieillissement physiologique (2 %) et les facteurs psychogènes (2,2 %). La plupart de ces cas sont dus à des infections virales et ne nécessitent pas d'antibiotiques dans la plupart des cas. Ces infections virales disparaissent après 1 à 2 semaines, et en cas de voix rauque persistante (plus de 4 semaines), l'American Academy of Otolaryngology recommande une visualisation directe avec une laryngoscopie avant le traitement par inhibiteurs de la pompe à protons, antibiotiques ou stéroïdes. Notre patiente présentait une voix rauque prolongée (plus de huit semaines), mais a bénéficié d'un délai rapide entre la visite en soins primaires et l'évaluation par laryngoscopie (moins de 2 semaines). Cela a conduit à son diagnostic et à son traitement par chimiothérapie et radiothérapie dans les trois mois suivant le diagnostic de carcinome épidermoïde du supraglotte. Le médecin de soins primaires est le premier point de visite pour les personnes souffrant de voix rauque. Il est important qu'ils soient informés et à jour des recommandations et des lignes directrices pour la prise en charge de cette condition, car un retard non justifié peut affecter le résultat global pour le patient. Ceci est particulièrement important chez les patients comme le nôtre présentant des facteurs de risque élevés, y compris la dépendance à la nicotine, la consommation d'alcool, l'exposition à l'amiante.

The effectiveness of various treatment approaches for laryngeal contact granulomas.

OBJECTIVES: To assess and compare the effectiveness of various treatment approaches for laryngeal contact granulomas (LCG). METHODS: A retrospective analysis was conducted on a cohort of 45 patients diagnosed with LCG at the Second Affiliated Hospital of Xi'an Jiaotong University from October 2017 to May 2023. Based on the treatment modalities administered, patients were categorized into three groups: acid suppression alone, hormone injection combined with acid suppression, and surgery combined with acid suppression. Subsequently, the study compared differences in treatment efficacy and average healing time among these three groups, using various indicators. RESULTS: The findings indicate that the granuloma size in LCG patients with hoarseness (0.126, 95% CI 0.087-0.288) was significantly greater compared to LCG patients without hoarseness (0.047, 95% CI 0.014-0.083) (P = 0.001). However, there were no significant variations in age, morphology (unlobulated/lobulated), laterality ratio (left/right), sex ratio (male/female), history of tracheal intubation (non-intubation/intubation), and RFS score (RFS > 7/RFS ≤ 7) (P > 0.05), regardless of the presence of hoarseness symptoms. At the treatment observation endpoint of 3 months, the curative ratio in the group receiving hormone injection combined with acid suppression was found to be significantly higher compared to the group receiving acid suppression alone (P = 0.018). In addition, the average healing time of patients in the hormone injection combined with acid suppression group was notably shorter than that of the acid suppression alone group (P = 0.007). CONCLUSIONS: The combination of hormonal injections and acid suppression may enhance the curative ratio and expedite the healing time of LCG.

An Atypical Cause of Hoarseness in a Patient With Thyroid Nodules.

Hoarseness due to vocal fold paresis (VFP) has a multitude of etiologies including systemic lupus erythematosus (SLE). During a clinical evaluation of a 58-year-old woman with long-standing hoarseness, an incidental finding of thyroid nodules was found to have VFP. Direct laryngoscopy and vocal fold biopsy confirmed the source was an inflammatory process involving the cricoarytenoid joint of the right hemilarynx. A presumptive diagnosis of SLE was made 3 years before meeting the clinical criteria of overt SLE. The VFP debut of SLE is extremely rare, and a literature review includes a handful of case reports (4 of a total of 37) since 1959. Only partial recovery of laryngeal function using glucocorticoids and Plaquenil was accomplished in the current case.

Comparison of the success rate of tracheal intubation between stylet and bougie with a hyperangulated videolaryngoscope: a randomised controlled trial.

Hyperangulated videolaryngoscopes are known to increase the success rate of tracheal intubation in the setting of difficult airway management when used with a stylet or bougie. However, there is controversy over which adjunct is more useful. This randomised study aimed to compare first attempt tracheal intubation success rate between a stylet and bougie when using a hyperangulated videolaryngoscope. We recruited patients aged > 20 years who were scheduled for elective surgery under general anaesthesia and required tracheal intubation. We only included patients with factors predicting difficult tracheal intubation based on pre-anaesthesia airway evaluation. Tracheal intubation was attempted using a Glidescope® with either a stylet or bougie as an adjunct according to group assignment. Primary outcome was the success rate of the first tracheal intubation attempt, and secondary outcomes were success of second and third attempts; tracheal intubation time; and occurrence of sore throat, dysphagia or hoarseness. A total of 166 patients were included. The success rate of the first tracheal intubation attempt was significantly higher in patients allocated to the bougie group compared with those allocated to the stylet group (81/83 (98%) vs. 73/83 (88%), respectively; p = 0.032). The number of patients who needed two attempts was significantly lower in those allocated to the bougie group compared with those allocated to the stylet group (1/83 (1%) vs. 9/83 (11%), respectively; p = 0.018). Each group had one patient (1%) where tracheal intubation was achieved after a third attempt. There was no significant difference in the occurrence of sore throat, dysphagia and hoarseness between the two groups. When difficult tracheal intubation is anticipated and a hyperangulated videolaryngoscope is used, the success rate of the first attempt is higher when a bougie is used compared with a stylet.

Clinical characteristics and prognosis of laryngeal tuberculosis combined with respiratory tuberculosis.

PURPOSE: To investigate the clinical characteristics, diagnosis and prognosis of patients with laryngeal tuberculosis (LTB) combined with respiratory tuberculosis. MATERIALS AND METHODS: A retrospective analysis was conducted on 134 patients who underwent endoscopy and were eventually diagnosed with LTB. The patients' demographic characteristics, clinical manifestations, endoscopic features, auxiliary examination, imaging examination and prognostic characteristics were analyzed. RESULTS: LTB patients had a median age of 45.5 years (range from 12 to 87 years) and a median course of 3.0 months (range from 0.1 to 72 months). The patients' symptoms mainly presented as hoarseness (97.0 %), abnormal sensation of pharyngeal (49.3 %), cough and sputum (41.0 %), pharyngalgia (39.6 %), dysphagia (10.4 %) and dyspnea (8.2 %). The positive rate of tuberculous symptoms was 25.4 %. Endoscopic features showed that the lesions mainly involved the glottis (87.3 %), presenting as unilateral lesions (66.7 %), near-full-length involvement (88.0 %), with mucosal waves significantly reduced (86.3 %), followed by supraglottis (43.3 %), subglottis (24.6 %) and the pharynx (15.7 %). The lesions may present as granulomatous proliferation (66.4 %), ulceration (65.7 %) or swelling and exudation (51.5 %). A total of 75 patients (56.0 %) were finally diagnosed with combined pulmonary tuberculosis (PTB), with a positive chest X-ray rate of 25.6 % and a positive chest CT rate of 71.2 %. A total of 42 patients who received anti-tuberculosis treatment were followed up, and 73.8 % of patients had significant improvement in symptoms. The morphology of the pharyngeal and laryngeal mucosa returned to basically normal (59.4 %) or scar-like (34.4 %). CONCLUSIONS: LTB is usually found in middle-aged men, and patients' symptoms are mainly hoarseness, abnormal sensation of pharyngeal, pharyngalgia, cough and sputum, and can be combined with tuberculous symptoms. These lesions mainly involve multiple subregions, mainly in the glottis, and can be combined with pharyngeal involvement. There were various types of lesions. Half of the patients were complicated with PTB, and chest CT was superior to X-ray in the detection of pulmonary lesions. After regular anti-tuberculosis treatment, the symptoms and morphology of the pharyngeal and laryngeal mucosa of most patients were significantly improved.

Effect of thermal softening of double-lumen endobronchial tubes on postoperative sore throat in patients with prior SARS-CoV-2 infection: a randomized controlled trial.

BACKGROUND: The incidence of postoperative sore throat (POST) after tracheal intubation using double-lumen endobronchial tubes (DLTs) is higher in patients with prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection than in the general population. This prospective trial was conducted to determine whether thermal softening of DLTs could decrease the incidence of POST or other airway injuries in patients with prior SARS-CoV-2 infection. METHODS: A total of 120 patients with prior SARS-CoV-2 infection undergoing thoracoscopic surgery were randomly assigned to two groups (n = 60 each). In the thermal softening group, the distal portion of the DLT was placed in thermostatic saline (50 °C) for 10 min before endotracheal intubation. In the control group, the distal portion of the DLT was placed in room temperature saline for 10 min before endotracheal intubation. The incidence and severity of POST and hoarseness were assessed at 1, 6 and 24 h postoperatively. The primary outcomes were the incidence and severity of POST at 6 h postoperatively. The secondary outcomes were the incidence and severity of hoarseness, vocal cord and tracheal injuries, and hemodynamic changes in patients at intubation. RESULTS: The incidence of POST at 6 h postoperatively was greater in the control group than in the thermal softening group [41 (68%) vs. 22 (37%), P = 0.001]. The overall incidence of POST at 24 h postoperatively was greater in the control group than in the thermal softening group [46 (76%) vs. 24 (40%), P < 0.001]. The overall incidence of tracheal injuries was also greater in the control group than in the thermal softening group (P = 0.016). Vocal cord injuries occurred more frequently in the control group than in the thermal softening group (P = 0.006). CONCLUSION: Thermal softening of DLTs before intubation can reduce the incidence of POST and airway injuries in patients with prior SARS-CoV-2 infection undergoing DLT insertion.

Effect of Esketamine Gargle on Postoperative Sore Throat in Patients Undergoing Double-Lumen Endobronchial Intubation: A Randomised Controlled Trial.

Background: Postoperative sore throat is a frequent adverse event after double-lumen endobronchial tube (DLT) intubation. The aim of this study was to investigate whether esketamine gargle has a preventive effect on the incidence of postoperative sore throat in patients undergoing DLT intubation. Methods: This trial included 140 patients undergoing elective thoracic surgery at the third affiliated hospital of Sun Yat-Sen University. Patients were randomly allocated into the following two groups of 70 patients each: the control group, gargling with saline of 30 mL, and the esketamine group, gargling with an esketamine solution of 30 mL (2 mL/50 mg esketamine in 28 mL saline), 5 min prior to anaesthesia induction. The primary outcome was the incidence of sore throat 24 h after surgery. The main secondary outcomes included the incidence of sore throat and hoarseness at 1 h and 48 h after surgery, as well as the intraoperative haemodynamic responses. Results: The incidence of sore throat was significantly higher in the control group (47.1%, 33/70 patients) compared with the esketamine group (12.9%, 9/70 patients) at 24 h after surgery (RD, 0.41; 95% confidence interval, 0.26-0.57; p < 0.001). Furthermore, the incidence of sore throat at 1 h (p = 0.027), 24 h (p = 0.019), and seventh day (p = 0.031) as well as hoarseness at 1 h (p = 0.027), 24 h (p = 0.019), and 48 h (p = 0.031) after surgery were reduced in the esketamine group. Significant differences were seen in the peak levels of systolic blood pressure, mean arterial blood pressure, and heart rate between the groups during the intubation (p < 0.05). Besides, no patient developed an adverse reaction to esketamine. Conclusion: Preoperative gargling of esketamine can provide an effect against sore throat after DLT intubation without adverse side effects and effectively inhibit sharp elevations in heart rate and blood pressure during double-lumen intubation procedures.

Comparing the effectiveness of topical dexamethasone emollient, lidocaine gel, and glycerin emollient on the endotracheal tube for postoperative hoarseness of voice, sore throat, and laryngospasm.

During general anesthesia, inserting a relatively stiff endotracheal tube using a metallic laryngoscope through the soft tissues of the pharynx and larynx, along with applying a pressured cuff, can result in varying degrees of tissue trauma and adverse outcomes. Anesthesiologists commonly encounter post-operative issues such as hoarseness, sore throat, and laryngospasm. This study aimed to compare the effectiveness of topical applications of dexamethasone emollient, lidocaine gel, and glycerin emollient in reducing these complications. One hundred patients were randomly assigned to four groups of 25 patients each: the control group (Group C), lidocaine gel group (Group L), glycerin emollient group (Group G), and dexamethasone emollient group (Group D). The assigned medication was topically applied to the endotracheal tube, and patients were monitored for postoperative laryngospasm, hoarseness, and sore throat within the first 24 hours. No statistically significant differences were found among the four groups in terms of demographic characteristics, postoperative sore throat, hoarseness, or laryngospasm (p>0.05). Lidocaine gel was an effective drug that can be used to attenuate the incidence rate of post-operative sore throat.
