RESUMEN
BACKGROUND: Different approach ultrasound-guided superior laryngeal nerve block was used to aid awake intubation, but little is known which approach was superior. We aimed to compare the parasagittal and transverse approaches for ultrasound-guided superior laryngeal nerve block in adult patients undergoing awake intubation. METHODS: Fifty patients with awake orotracheal intubation were randomized to receive either a parasagittal or transverse ultrasound-guided superior laryngeal nerve block. The primary outcome was patient's quality of airway anesthesia grade during insertion of the tube into the trachea. The patients' tube tolerance score after intubation, total procedure time, mean arterial pressure, heart rate, Ramsay sedation score at each time point, incidence of sore throat both 1 h and 24 h after extubation, and hoarseness before intubation, 1 h and 24 h after extubation were documented. RESULTS: Patients' quality of airway anesthesia was significantly better in the parasagittal group than in the transverse group (median grade[IQR], 0 [0-1] vs. 1 [0-1], P = 0.036). Patients in the parasagittal approach group had better tube tolerance scores (median score [IQR],1[1-1] vs. 1 [1-1.5], P = 0.042) and shorter total procedure time (median time [IQR], 113 s [98.5-125.5] vs. 188 s [149.5-260], P < 0.001) than those in the transverse approach group. The incidence of sore throat 24 h after extubation was lower in the parasagittal group (8% vs. 36%, P = 0.041). Hoarseness occurred in more than half of the patients in parasagittal group before intubation (72% vs. 40%, P = 0.023). CONCLUSIONS: Compared to the transverse approach, the ultrasound-guided parasagittal approach showed improved efficacy in terms of the quality of airway topical anesthesia and shorter total procedure time for superior laryngeal nerve block. TRIAL REGISTRATION: This prospective, randomized controlled trial was approved by the Ethics Committee of Nanjing First Hospital (KY20220425-014) and registered in the Chinese Clinical Trial Registry (19/6/2022, ChiCTR2200061287) prior to patient enrollment. Written informed consent was obtained from all participants in this trial.

OBJECTIVES: To evaluate the effectiveness of peri-intubation non-pharmacological interventions in reducing postoperative sore throat (POST), cough (PEC), and hoarseness in surgical patients. DESIGN: A systematic review with meta-analysis and meta-regression. SETTING: Elective surgery under general anesthesia in operating rooms. MAIN OUTCOME MEASURES: Evaluate the impact of non-pharmacological interventions, including pre-intubation (gargling with Sodium Azulene Sulfonate, licorice, or using Strepsils tablets of honey and lemon lozenge), during-intubation (inflating the TT cuff with normal saline and softening the ETT cuff with warm normal saline), and post-intubation (cold vapor therapy, gargling with honey lemon water, and using green tea gargle), on the occurrence of POST, PEC, and hoarseness. RESULTS: Nineteen trials with 2,136 participants were included. Pre-intubation intervention significantly reduced POST immediately after extubation (n = 861; OR: 0.28, 95 % CI: 0.20-0.38, P < 0.001), and 24 h post-extubation (n = 1006; OR: 0.21, 95 % CI: 0.16-0.28, P < 0.001). During-intubation intervention did not show significant effects on POST. Pre-intubation intervention also reduced POST-associated pain score at 24 h post-extubation (n = 440; MD: -0.50, 95 % CI: -0.81 to -0.18, P < 0.001). Post-intubation interventions were effective in reducing POST-associated pain scores at different time points post-extubation (P < 0.05). Pre-intubation intervention significantly reduced PEC (OR: 0.13, 95 % CI: 0.02-0.70, P = 0.02) and hoarseness (OR: 0.36, 95 %CI: 0.15-0.86, P = 0.02) at 24 h post-extubation. However, during-intubation interventions did not reduce hoarseness at 24 h post-extubation. CONCLUSION: Pre-intubation non-pharmacological interventions were found to be the most effective in reducing the incidence and severity of POST, PEC, and hoarseness. IMPLICATIONS FOR CLINICAL PRACTICE: Implementing pre-intubation non-pharmacological interventions can be beneficial for bedside nurses and healthcare professionals in reducing postoperative complications and nurses can contribute to improving patient comfort and recovery outcomes following surgery. SYSTEMATIC REVIEW PROTOCOL: The protocol was registered in the PROSPERO international prospective register of systematic reviews on 2 January 2024 (CRD42023492813).

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 (Pâ <â .05). In addition, group B had a significantly lower incidence of coughing at 24 hours (Pâ =â .047). Compared with group A, the severity of POST was significantly lower at 6 (Pâ =â .027), 12 (Pâ =â .004), and 24 (Pâ =â .005) hours at rest, and at 6 (Pâ =â .002), 12 (Pâ =â .038), and 24 (Pâ =â .015) hours during swallowing in group B. The incidence and severity of hoarseness were comparable at each time-point between the 2 groups (Pâ >â .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.

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.

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.

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.

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.

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.

BACKGROUND: Postoperative sore throat (POST) is one of the more common side effects of tracheal intubation patients under general anesthesia (GA) after extubation using double-lumen endobronchial tubes (DLTs). The internal branches of the superior laryngeal nerve (SLN) block (iSLNB) have been reported to anesthetize the larynx for airway manipulation (such as awake tracheal intubation) and pain treatment efficiently. We hypothesized that ultrasound-guided iSLNB (US-guided iSLNB) combined with GA would ameliorate the incidence and severity of POST and hoarseness. METHODS: Patients (n = 82) undergoing thoracoscopic resection of pulmonary nodules/lobes/segments with one-lung ventilation (OLV) under GA were randomized into 2 groups depending on whether performed with iSLNB (S group, n = 41) or not (C group, n = 41) under GA. Patients in the S group received US-guided iSLNB bilaterally before surgery. POST and hoarseness were assessed at 2, 6, and 24 hours after surgery. The primary outcome of this study was the incidence of POST at 6 hours after surgery between groups. RESULTS: The overall accumulated incidence of POST was lower in the S goup than in the C group (9/41 vs 20/41; 95% CI, 0.30 [0.11-0.77]; P = .011). The incidence and severity of POST was lower in the S group than in the C group at 2 hours (9/41 vs 20/41; 95% CI, 0.30 [0.11-0.77]; P = .008 and P = .004) and 6 hours after (7/41 vs 17/41; 95% CI, 0.29 [0.10-0.81]; P = .012 and P = .015) surgery. The incidence and severity of POST at 24 hours after surgery was nonsignificant. However, the incidence and severity of hoarseness was comparable between the 2 groups at 2, 6, and 24 hours after surgery. CONCLUSIONS: Preoperative US-guided iSLNB could significantly ameliorate the incidence and severity of POST induced by double-lumen bronchial catheter intubation.

STUDY OBJECTIVE: The combined use of the ProSeal laryngeal mask airway and a bronchial blocker may reduce postoperative hoarseness and sore throat. We aimed to test the feasibility and efficacy of this combination technique in thoracoscopic surgery. DESIGN: A single-center, patient-assessor blinded, randomized controlled trial. SETTING: Nagoya City University Hospital (between November 2020 and April 2022). PATIENTS: A total of 100 adult patients undergoing lobectomy or segmentectomy by video- or robotic-assisted thoracoscopic surgery. INTERVENTIONS: Patients were randomly assigned to either group using a combination of the ProSeal laryngeal mask airway and a bronchial blocker (pLMA+BB group) or a double-lumen endobronchial tube (DLT group). MEASUREMENTS: The primary outcome was the hoarseness incidence on 1-3 postoperative days. Secondary outcomes included sore throat, intraoperative complications (hypoxemia, hypercapnia, surgical interruption, malposition of devices, unintended lung expansion, and ventilatory difficulty), lung collapse, device placement-related outcomes, and coughing during emergence. MAIN RESULTS: A total of 100 patients underwent randomization (51 to the pLMA+BB group and 49 to the DLT group). After drop outs, a total of 49 patients in each group were analyzed per-protocol. The incidences of hoarseness in the pLMA+BB and DLT groups were 42.9% and 53.1% (difference, -10.2%; 95% confidence interval, -30.1% to 10.3%; p = 0.419), 18.4% vs. 32.7%, and 20.4% vs. 24.5% on postoperative day 1, 2, and 3, respectively. The incidences of sore throat in the pLMA+BB and DLT groups were 16.3% vs. 34.7% (difference, -18.4%; 95% confidence interval, -35.9% to -0.9%; p = 0.063) on postoperative day 1. In the pLMA+BB group, more intraoperative complications and less coughing during emergence were observed compared to the DLT group. Lung collapse and placement-related outcomes were comparable between the groups. CONCLUSIONS: The combination of ProSeal laryngeal mask airway and bronchial blocker did not significantly reduce hoarseness compared to the double-lumen endobronchial tube.

BACKGROUND: Misplacement of double-lumen endobronchial tubes (DLTs) during bronchial intubation, especially when bronchoscopy guidance is not applicable, threatens effective lung isolation and brings about airway injury during reposition. We aimed to examine whether a novel maneuver called right tracheal displacement (RTD) can reduce left-sided DLT misplacement during first-attempt intubation without bronchoscopy guidance. METHODS: Patients that underwent thoracic surgeries requiring one-lung ventilation during November 2020 to January 2021 were recruited and randomized into control and RTD group, with 54 cases in each group. The primary outcomes included the incidence of DLT misplacement and the time to complete desired bronchial intubation. The secondary outcomes included mucosal injury, sore throat and hoarseness upon emergence and at 24 h post-operatively. RESULT: The incidence of DLT misplacement in RTD group was significantly lower compared to control group (0% vs. 16.7%) The time to complete bronchial intubation was also significantly shortened in RTD group compared to control (52.88 ± 9.36 s vs. 63.04 ± 20.02 s). The incidence of mucosal injury, sore throat and hoarseness were comparable between two groups. CONCLUSION: RTD maneuver can effectively improve the success rate of first-attempt proper DLT positioning and shorten the time required by bronchial intubation. TRIAL REGISTRATION: This prospective, double-blind, randomized study has completed the registration of the Chinese Clinical Trial Center at 2/11/2020 with the registration number ChiCTR2000040212. It was conducted from 26/11/2020 to 31/7/2021 in third affiliated hospital of Sun Yat-sen university.

OBJECTIVE: Tracheal intubation-related complications, such as postoperative sore throat (POST), hoarseness, and vocal cords injuries, are not uncommon. It is well known that thermal softening of double-lumen endobronchial tubes (DLTs) has been used to prevent these events from happening in non-smokers; however, no study has ever assessed the effects of thermal softening of DLTs in smokers undergoing one-lung anesthesia. The authors aimed to investigate whether thermal softening of DLT can achieve a better effect in preventing POST. DESIGN: A total of 258 smokers scheduled for one-lung anesthesia were randomly assigned to 1 of the following 2 groups: (1) group C (non-thermal softening group) and (2) group T (DLTs were placed in 40°C 0.9% saline for 10 minutes). Incidence and severity of POST and hoarseness were assessed until 48 hours after surgery. Vocal cords were examined using laryngoscope before intubation and immediately after extubation. Patients' hemodynamic change at intubation and extubation was recorded. The primary outcomes were the incidence and severity of POST. The secondary outcomes were the incidence and severity of hoarseness, vocal cords injuries, and patients' hemodynamic change at intubation and extubation. MEASUREMENTS AND MAIN RESULTS: Sore throat and vocal cord injuries occurred less frequently in the thermal softening group than in the control group (31/129 v 60/129, p < 0.01; 21/129 v 49/129, p < 0.001; 12/129 v 35/129, p < 0.001 for sore throat; 14/70 v 27/70, risk ratio (95% confidence interval): 0.52 (0.30-0.90), p = 0.025 for sore throat; 5/129 v 52/129, p < 0.05 for vocal cord injuries). CONCLUSION: Thermal softening of DLTs significantly reduced the incidence and severity of DLTs intubation-related POST within 72 hours after extubation.

BACKGROUND: There are doubts among anesthesiologists on the use of the Laryngeal Mask Airway (LMA) in nasal surgeries because of concerns about the occurrence of blood leakages to the airway. We hypothesized that the use of LMA-Supreme (LMA-S) in nasal surgery is comparable with endotracheal tube (ETT) according to airway protection against blood leakage through the fiberoptic bronchoscopy, oropharyngeal leakage pressure (OLP), heart rate (HR), mean arterial pressure (MAP), and postoperative adverse events. METHODS: The present study was conducted in a prospective, randomized, single-blind, controlled manner on 80 patients, who underwent septoplasty procedures under general anesthesia, after dividing them randomly into two groups according to the device used (LMA-S or ETT). The presence of blood in the airway (glottis/trachea, distal trachea) was analyzed with the fiberoptic bronchoscope and a four-point scale. Both groups were evaluated for OLP; HR; MAP; postoperative sore throat, nausea, and vomiting; dysphagia; and dysphonia. RESULTS: In the fiberoptic evaluation of the airway postoperatively, less blood leakage was detected in both anatomic areas in the LMA-S group than in the ETT group (glottis/trachea, p = 0.004; distal trachea, p = 0.034). Sore throat was detected less frequently in the LMA-S group at a significant level in the 2nd, 6th, and 12th hours of postoperative period; however, other adverse events were similar in both groups. Hemodynamic parameters were not different between the two groups. CONCLUSION: The present findings demonstrate that the LMA-S provided more effective airway protection than the ETT in preventing blood leakage in the septoplasty procedures. We believe that the LMA-S can be used safely and as an alternative to the ETT in septoplasty cases. TRIAL REGISTRATION: This trial is registered at the US National Institutes of Health ( ClinicalTrials.gov ) # NCT03903679 on April 5, 2019.

BACKGROUND: This quality improvement (QI) project was performed at a single center to determine the incidence of postoperative complications associated with use of cuffed airway devices. An educational program was then completed that involved training our anesthesia providers about complications related to excessive cuff pressure and how to utilize a quantitative cuff pressure measurement device (manometer). The impact of this educational initiative was assessed by comparing the incidence of postoperative complications associated with the use of airway devices before and after the training period. METHODS: After approval by our institution's Institutional Review Board, a pre-intervention (baseline) survey was obtained from 259 adult patients after having undergone surgery with general anesthesia with the use of an endotracheal tube (ETT) or laryngeal mask airway (LMA). Survey responses were used to determine the baseline incidence of sore throat, hoarseness, and dysphagia. Once these results were obtained, education was provided to the anesthesia department members addressing the complications associated with excessive cuff pressures, appropriate cuff pressures based on manufacturer recommendations, and instructions on the use of a quantitative monitor to determine cuff pressure (manometry). Clinical care was then changed by requiring intraoperative cuff pressure monitoring throughout our institution for all surgical patients. After this educational period, 299 patients completed the same survey describing postoperative airway complications. RESULTS: The use of manometry reduced the incidence of moderate-to-severe postoperative sore throat in the pre- vs. post-intervention groups (35 patients vs 31 patients, p = 0.045), moderate to severe hoarseness (30 patients vs 13, patients p = 0.0001), and moderate-to-severe dysphagia (13 patients vs 5 patients, p = 0.03). CONCLUSION: Caring for patients in the perioperative setting frequently entails placement of an airway device. This procedure is associated with several potential complications, including sore throat, coughing, and vocal cord damage. Our quality improvement initiative has shown that intraoperative management of intra-cuff pressure based on manometry is feasible to implement in clinical practice and can reduce postoperative airway complications.

BACKGROUND: Sore throat is a remarkable complication after thyroid surgery with endotracheal tube (ETT). Many studies revealed that laryngeal mask airway (LMA) might reduce the incidence and severity of postoperative sore throat. However, little is known about the use of a flexible reinforced LMA (FLMA) in thyroid surgery. The purpose of this study was to explore the potential benefits of FLMA compared with ETT on postoperative sore throat. METHODS: In this prospective, single-blinded, randomized, controlled trial, ninety-six patients aged 20-80 years, scheduled for elective radical thyroidectomy under general anesthesia were enrolled. They were randomly divided into ETT group and FLMA group. All the included patients received total intravenous anesthesia (with propofol, fentanyl and rocuronium) and controlled mechanical ventilation during the surgery. Cuff pressure of ETT and FLMA were strictly controlled. Incidence and severity of postoperative sore throat, numbness and hoarseness at 1, 24, and 48 h after surgery was evaluated and compared between the two groups. Incidence and severity of buckling during extubation and the hemodynamic profile during intubation were also recorded and compared. RESULTS: The incidence of sore throat and hoarseness was significantly lower in FLMA group than those in ETT group at 1 h, 24 h and 48 h postoperatively, as well as the severity of sore throat. Compared to ETT group, there was a significantly lower incidence of buckling during extubation and less fluctuation of HR and BP at 1 min and 3 min after intubation in FLMA group. CONCLUSIONS: Patients undergoing thyroid surgery with FLMA had less postoperative laryngopharyngeal symptoms when compared with ETT. The use of FLMA also achieved less buckling during extubation and better hemodynamic profiles during intubation. TRIAL REGISTRATION: The research was registered in Chinese Clinical Trial Registry (ChiCTR-IOR-15006602) on May 23th, 2015.

PURPOSE: Postoperative sore throat (POST) is a relatively common morbidity. Topical lidocaine lubricants have been proposed to prevent POST; however, their effectiveness remains uncertain. This meta-analysis aimed to evaluate the prophylactic effect of lidocaine lubrications against POST, cough, and hoarseness in adult patients after surgery. METHODS: Randomized-controlled trials from PubMed, Embase, the Cochrane Library, and the ClinicalTrials.gov registry that were published from inception until 26 March 2018 were included that compared the effectiveness of lidocaine lubricants with that of controls in preventing the incidence of overall POST and moderate to severe POST (POSTMS) at the first and 24th postoperative hour (POST-1h, POST-24h, POSTMS-1h, and POSTMS-24h). Postoperative cough and hoarseness at the 24th postoperative hour were also studied. Bias assessment and subgroup, sensitivity, and trial sequential analyses were also performed. RESULTS: Fourteen randomized-controlled trials (n = 2146) were selected. The incidences of POST-1h and POST-24h were 41.1 % and 22.6 % for the lidocaine group, and 41.9% and 23.5% for the control group, respectively. No effect was found on any of the outcome measurements. The overall risk ratios were 1.11 (95% confidence interval [CI], 0.82 to 1.51) and 1.06 (95% CI, 0.37 to 3.02) for the incidence of POST-1h and POSTMS-1h, respectively; 0.99 (95% CI, 0.83 to 1.17) and 0.49 (95% CI, 0.16 to 1.50) for POST-24h and POSTMS-24h, respectively; and, 1.09 (95% CI, 0.71 to 1.66) and 0.91 (95% CI, 0.66 to1.24) for postoperative cough (PC)-24h and postoperative hoarseness (PH)-24h, respectively. CONCLUSION: Lidocaine lubricants applied on the tips of endotracheal tube are not effective against the morbidities of POST, PC, and PH.

RéSUMé: OBJECTIF: Les maux de gorge postopératoires sont une morbidité relativement fréquente. Les lubrifiants topiques à base de lidocaïne ont été proposés pour prévenir les maux de gorge postopératoires, mais leur efficacité demeure incertaine. Cette méta-analyse avait pour objectif d'évaluer l'effet prophylactique des lubrifications de lidocaïne contre les maux de gorge postopératoires, la toux et l'enrouement de la voix chez les patients adultes après une chirurgie. MéTHODE: Nous avons inclus les études randomisées contrôlées publiées sur PubMed, Embase, la Cochrane Library et le registre de ClinicalTrials.gov entre leur création et le 26 mars 2018 qui comparaient l'efficacité des lubrifiants à base de lidocaïne par rapport à l'absence de traitement pour prévenir l'incidence des maux de gorge postopératoires globaux et des maux de gorge postopératoires modérés à graves à la première et à la vingt-quatrième heure postopératoire (POST-1h, POST-24h, POSTMS-1h, et POSTMS-24h). La toux et l'enrouement à 24 heures postopératoires ont également été étudiés. Des analyses d'évaluation du biais et de sous-groupe, de sensibilité et des analyses séquentielles d'essais ont également été réalisées. RéSULTATS: Quatorze études randomisées contrôlées (n = 2146) ont été sélectionnées. Les incidences de POST-1h et de POST-24h étaient de 41,1 % et 22,6 % dans le groupe lidocaïne, et de 41,9 % et 23,5 % dans le groupe témoin, respectivement. Aucun effet n'a été observé pour aucun de nos critères d'évaluation. Les rapports de risque globaux étaient de 1,11 (intervalle de confiance [IC] 95 %, 0,82 à 1,51) et de 1,06 (IC 95 %, 0,37 à 3,02) pour l'incidence de POST-1h et de POSTMS-1h, respectivement; de 0,99 (IC 95 %, 0,83 à 1,17) et de 0,49 (IC 95 %, 0,16 à 1,50) pour les POST-24h et POSTMS-24h, respectivement; et de 1,09 (IC 95 %, 0,71 à 1,66) et 0,91 (IC 95 %, 0,66 à 1,24) pour la toux postopératoire (PC)-24h et l'enrouement postopératoire (PH)-24h, respectivement. CONCLUSION: Les lubrifiants à base de lidocaïne appliqués sur l'extrémité distale du tube endotrachéal ne sont pas efficaces pour prévenir les morbidités de maux de gorge, de toux et d'enrouement postopératoires.

PURPOSE: Anterior cervical spine surgery is associated with postoperative dysphagia, sore throat and dysphonia. It is unclear, whether this is caused by increased endotracheal tube (ETT) cuff pressure after retractor placement. This study aims to assess the effect of ETT cuff pressure adjustment on postoperative dysphagia, sore throat and dysphonia. METHODS: In this, single-centre, observer and patient-blinded randomized controlled trial patients treated with anterior cervical spine surgery were randomized to adjustment of the ETT cuff pressure to 20 mmHg after placement of the retractor versus no adjustment. Primary outcome was the incidence and severity of postoperative dysphagia. Secondary outcomes were sore throat and dysphonia. Outcomes were evaluated on day one and 2 months after the operation. RESULTS: Of 177 enrolled patients, 162 patients (92.5%) could be evaluated. The incidence of dysphagia was 75.9% on day one and 34.6% 2 months after surgery. Dysphagia in the intervention and control group was present in 77.8% versus 74.1% of patients on day one (odds ratio (OR) 1.2, 95% confidence interval (CI) (0.6-2.5)) and 28.4% versus 40.7% of patients after 2 months (OR 0.6, 95% CI 0.3-1.1), respectively. Severity of dysphagia, sore throat and dysphonia was similar in both groups. CONCLUSIONS: Anterior cervical spine surgery is accompanied by a high incidence of postoperative dysphagia, lasting until at least 2 months after surgery in over a third of our patients. Adjusting ETT cuff pressure to 20 mmHg after retractor placement, as compared to controls, did not lower the risk for both short- and long-term dysphagia.

INTRODUCTION: Blindly administered bilateral (B/L) superior laryngeal nerve (SLN) blocks, have been used to decrease the perioperative stress response of endoscopic laryngosurgeries. Use of ultrasound (USG) for giving these blocks is more likely to be successful, with fewer complications. We evaluated the efficacy of USG guided B/L SLN block in decreasing perioperative cough, sore-throat and hoarseness of voice. MATERIAL AND METHODS: This study was conducted on forty patients undergoing endoscopic laryngosurgery under GA. Patients were randomized into two groups of 20 patients each. Patients in group C received GA, whereas those in group L received USG-guided SLN block bilaterally with 2.5â¯ml of 2% lignocaine, along with GA. Postoperative cough, sore throat and hoarseness of voice was measured at 30â¯min, 2â¯h, 4â¯h and 24â¯h following transfer to post-anesthesia care unit. RESULTS: Patients receiving SLN block had significantly lower incidence of perioperative cough (20% in group L vs 90% in group C; p value - 0.0001) as well as sore throat (5% in group L vs 95% in group C; p value - 0.0001). In these patients, severity of hoarseness of voice was greater in the early postoperative period (100% in group L vs 70% in group C; p value - 0.027), while it decreased significantly at 24â¯h postoperatively(0.0% in group L vs 30% in group C; p value - 0.027). CONCLUSION: USG guided SLN block as an adjuvant to GA resulted in better recovery profile of the patients with significant reduction in postoperative cough, sore throat and hoarseness of voice.

BACKGROUND: Postoperative sore throat (POST), hoarseness, and cough after tracheal intubation are not uncommon. Although both lidocaine and dexamethasone have been used independently to reduce these events, there is no study assessing the combined effects of lidocaine and dexamethasone. METHODS: This prospective, double-blind, randomized controlled study enrolled 180 patients requiring general anesthesia with endotracheal intubation for >90 minutes. They received 1 of the 4 intravenous agents just before induction of anesthesia: lidocaine (1.5 mg/kg) in group L, dexamethasone (8 mg) in group D, lidocaine (1.5 mg/kg) with dexamethasone (8 mg) in group DL, and placebo as normal saline in group NS. Standard anesthesia protocol was followed. Incidence and severity of a sore throat, cough, and hoarseness of voice were assessed up to 24 hours postoperatively. The primary outcome was the incidence of POST, and the main effects of dexamethasone and lidocaine were the primary interest. RESULTS: Data of 45 patients in D, 44 in L, 44 in DL, and 43 in NS groups were analyzed. The incidence of a sore throat was 36%, 43%, 25%, and 56% in group D, L, DL, and NS, respectively (P = .02). Dexamethasone with or without lidocaine reduced the incidence of the POST (odds ratio, 0.44; 95% confidence interval, 0.24-0.82; P < .01). However, lidocaine was not effective in reducing POST (odds ratio, 0.62; 95% confidence interval, 0.33-1.14; P = .12). No difference was observed in the severity of a sore throat, incidence and severity of a cough, and hoarseness among the groups. CONCLUSIONS: Dexamethasone, with or without lidocaine, was effective in reducing the incidence of POST in patients requiring prolonged tracheal intubation.

BACKGROUND: A right-sided double-lumen tube (R-DLT) tends to obstruct the right upper lobe intraoperatively due to anatomical distortion during surgery. If the R-DLT is poorly matched with the patient's airway anatomy, it will not be possible to correctly replace the tube with a fiberoptic bronchoscope (FOB). In our study, we aimed to explore an efficient method for difficult repositioning caused by right upper lobe occlusion during surgery: repositioning the R-DLT from the right main bronchus into the left main bronchus. The current study was designed to assess the efficacy and safety of this method. METHODS: Sixty adult patients scheduled to undergo left-sided thoracic surgery were randomly assigned to two groups. With the patient in the right lateral position during surgery, the R-DLT was pulled back to the trachea while being rotated 90° clockwise; it was then either rotated 90° clockwise for placement into the left main bronchus (Group L) or rotated 90° anticlockwise and returned to the right main bronchus (Group R) using FOB guidance. The primary outcomes included clinical performance, which was measured by intubation time, and the quality of lung collapse. A secondary outcome was safety, which was determined according to bronchial injury and vocal cord injury. RESULTS: The median intubation time (IQR [range]) required for placement of a R-DLT into the left main bronchus was shorter than the time required for placement into the right main bronchus (15.0 s [IQR, 12.0 to 20.0 s]) vs 23.5 s [IQR, 14.5 to 65.8 s], P = 0.005). The groups showed comparable overall results for the quality of lung collapse during the total period of one-lung ventilation (P = 1.000). The numbers of patients with bronchial injuries or vocal cord injuries were also comparable between groups (Group R, 11/30 vs. Group L 8/30, P = 0.580 for bronchus injuries; Group R, 15/30 vs. Group L 13/30, P = 0.796 for vocal cord injuries). CONCLUSIONS: Repositioning a R-DLT from the right main bronchus into the left main bronchus had good clinical performance without causing additional injury. This may be an efficient method for the difficult repositioning of a R-DLT due to right upper lobe occlusion during surgery.
