[PMID: 38935009 DOI: 10.1016/j.jopan.2024.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 03/07/2024] [Accepted: 03/10/2024] [Indexed: 06/28/2024]
Abstract
PURPOSE Examine the effectiveness of using intracuff lidocaine to minimize postoperative complications. DESIGN Systematic review. METHODS This review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Guidelines. PubMed, CINAHL, Cochrane, Google Scholar, and gray literature databases were searched to obtain eligible studies and minimize selection bias. The Johns Hopkins Nursing Evidence-Based Practice Model was used to appraise the level of evidence for the varying studies. Only randomized controlled trials (RCT) and systematic reviews with meta-analyses of RCTs were included in the review. FINDINGS Three RCTs and three systematic reviews with meta-analyses incorporating a total of 2,337 patients were included in this review. Intracuff lidocaine (alkalinized and nonalkalinized) had the lowest incidence of postoperative sore throat in the early and late postoperative periods compared to intracuff air or intracuff saline. Furthermore, the evidence suggested that the use of intracuff lidocaine reduced postextubation cough and the incidence of hoarseness but had little or no effect on dysphagia. All studies were Level 1 and Grade A, indicating clinically solid evidence in analyzing intracuff lidocaine's effect on all outcomes measured. CONCLUSIONS The current literature suggests the feasibility of using intracuff lidocaine as an effective method to reduce the incidence of postoperative sore throat, postextubation cough, and hoarseness. The implications to practice include improving the norm of postoperative throat mucosal injuries by implementing an evidence-based practice intervention of intracuff lidocaine.

The effect of different endotracheal tube cuff pressure monitoring systems on postoperative sore throat in patients undergoing tracheal intubation: a randomized clinical trial. BMC Anesthesiol 2024; 24:115. [PMID: 38528475 PMCID: PMC10962134 DOI: 10.1186/s12871-024-02499-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 03/15/2024] [Indexed: 03/27/2024] Open
Abstract
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.

Abstract
Background Postoperative sore throat is the most frequent complication in pediatric patients after general anesthesia. This study aimed to investigate the incidence of postoperative sore throat in patients undergoing general anesthesia with tracheal intubation or laryngeal mask airway. Methods A hospital-based multicenter prospective observational cohort study was conducted. Proportional allocation was done with a total of 424 patients from March 1 to June 30, 2022. The information was entered into the Epi-Data software version 4.6 and analyzed with Stata 14. Socio-demographic, surgical, and anesthetic-related characteristics were analyzed using descriptive statistics. A p-value of less than 0.2 was the cutpoint of bivariate logistic regression analysis, and p-values of less than 0.05 were regarded as statistically significant in multivariate logistic regression to determine the presence and strength of association between independent variables and postoperative sore throat. Results A total of 411 patients were included in this study, with a response rate of 96.9%. The overall proportion of patients who developed postoperative sore throat was 45% (95% CI: 40.18-49.84). Patients who had anesthesia for more than two hours (AOR = 8.23: 95% CI = 4.08-16.5), those who were intubated by undergraduate anesthesia students (AOR = 2.67: 95% CI = 1.53-4.67), and those who had been intubated using tracheal tube (AOR = 2.38: 95% CI = 1.15-4.92) were significantly associated with the level of postoperative sore throat. Conclusions and recommendations We concluded that intubated children with ETT have a high incidence of post-operative sore throat. Tracheal tube usage, intubation by undergraduate students, and more than two hours of anesthesia duration were associated factors. The incidence of sore throat can be decreased with the use of a laryngeal mask airway, intubation by a senior anesthetist, and shortening of anesthesia time.

Abstract
BACKGROUND The incidence of cough reflex during extubation is 76%. Cough reflex causes severe hemodynamic fluctuations and airway complications. This prospective trial investigated the potential effects of tracheal tube cuff deflation on cough reflex during extubation. METHODS One hundred and twenty-six patients scheduled for operations within 3 h under general anaesthesia with orotracheal intubation were randomly assigned to one of three groups: control (C), experimental (E) or syringe (S) groups. Patients in group C underwent tracheal tube cuff deflation using a 10-ml syringe in 1 s, patients in group E underwent tracheal tube cuff deflation continuously and slowly in 5 s using a cuff pressure gauge until the pressure was zero and patients in group S underwent tracheal tube cuff deflation using a 10-ml syringe at a speed of 1 ml s-1. The incidence and severity of cough reflexs during extubation and the incidence of postoperative airway complications within 48 h were assessed. RESULTS Compared with group C (60.0%), the incidence of cough reflex in group E was 9.8% (p < 0.001) and in group S was 12.5% (p < 0.001). The severity of cough reflex was graded as 2 (1-2) in group C, 1 (1-1) in group E and 1 (1-1) in group S (p < 0.001 for group comparisons). The incidence of hoarseness in group C was 0.0%, in group E was 19.5% and in group S was 5.0% (p < 0.05 for all groups, p = 0.009 between group C and E). CONCLUSIONS Compared with deflating a trachal tube cuff with a 10-ml syringe in 1 s, the use of a 10-ml syringe at a speed of 1 ml s-1 or a cuff pressure guage within 5 s can both reduce the incidence of cough reflex, but deflating with a cuff pressure guage can increase the incidence of postoperative hoarseness.

Abstract
BACKGROUND Post-extubation cough is a common phenomenon in surgical patients undergoing general anesthesia, which can lead to potentially dangerous complications. In this meta-analysis, we evaluated the efficacy and safety of intracuff alkalinized lidocaine in patients with tracheal intubation to prevent cough and other airway complications during the perioperative period.
AIM To perform a systematic review and meta-analysis of intracuff alkalinized lidocaine for the prevention of postoperative airway complications.
METHODS PubMed, Embase, Cochrane, and Web of Science were searched for randomized controlled trials (RCTs) that compared intracuff alkalinized lidocaine to placebo. We used risk-of-bias assessment to assess the RCTs, and the quality of evidence was assessed using the grading of recommendations, assessment, development, and evaluations.
RESULTS Twelve randomized trials (1175 patients) were analyzed. Meta-analysis showed that intracuff alkalinized lidocaine was associated with less cough compared to that produced by placebo [risk ratio (RR): 0.38; 95% confidence interval (CI): 0.23-0.63]. Similarly, intracuff alkalinized lidocaine was more effective than the control in reducing postoperative sore throat at 24 h (RR: 0.19; 95%CI: 0.09-0.41) and postoperative hoarseness (RR: 0.38; 95%CI: 0.21-0.69).
CONCLUSION Intracuff alkalinized lidocaine is an effective adjuvant that can decrease airway complications, such as coughing, hoarseness, and sore throat.

Abstract
Sore throat after tracheal intubation impairs postoperative recovery. We randomly allocated 172 ASA physical status 1-2 participants, scheduled for laparoscopic lower abdominal surgery, to tracheal intubation with larger tubes (n = 88) or smaller tubes (n = 84), with internal diameters 7.5-mm vs. 6.5-mm for men and 7.0-mm vs. 6.0-mm for women. Primary outcome was the rates of no, mild, moderate or severe sore throat 1 h after surgery, which were 60, 10, 17 and 1 with larger tracheal tubes and 79, 5, 0 and 0 with smaller tubes, p < 0.001. The equivalent rates 24 h after surgery were 64, 16, 8 and 0 vs. 74, 6, 3 and 1, p = 0.037. Intra-operative ventilatory variables were unaffected by tube diameter, including peak inspiratory pressure, plateau pressure and end-tidal carbon dioxide partial pressure. In summary, smaller tracheal tubes benefitted patients having laparoscopic operations.

Abstract
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.

Abstract
BACKGROUND Endotracheal tube cuff (ETTc) inflation pressure is usually not regarded as an important aspect during intubation. In this study, we compared measuring ETTc pressure and pilot balloon palpation method in causing post-operative airway complications. METHODS Two hundred and ninety-two surgical patients requiring intubation were recruited into this prospective, double-blind, randomised controlled study. Group A patients had their ETTc initially inflated, checked by a cuff pressure gauge, recorded and then set to 25 cmH2O. Group B patients had their ETTc inflated using the pilot balloon palpation method. Patients were then followed up for post-operative sore throat, hoarseness and cough. RESULTS The overall incidence of post-operative sore throat was 39.0% versus 75.3% (P < 0.001), hoarseness 6.2% versus 15.1% (P < 0.05) and cough 7.5% versus 21.9% (P < 0.05) in Group A and B, respectively. Group A patients experienced a significant reduction in the incidence and severity of sore throat up to 24 h post-operatively (P < 0.001), hoarseness at the first hour (P = 0.004) and cough at first and 12 h post-operatively (P = 0.002). CONCLUSION Adjusting the ETTc pressure to 25 cmH2O reduces post-operative sore throat, hoarseness and cough compared to pilot balloon palpation method.

Abstract
Background: Sevoflurane is widely used to anesthetize children because of its rapid action with minimal irritation of the airways. However, there is a high risk of agitation after emergence from anesthesia. Strabismus surgery, in particular, can trigger agitation because patients have their eyes covered in the postoperative period. The aim of this study was to determine whether or not esmolol and lidocaine could decrease emergence agitation in children. Methods: Eighty-four patients aged 3 to 9 years undergoing strabismus surgery were randomly assigned to a control group (saline only), a group that received intravenous lidocaine 1.5 mg/kg, and a group that received intravenous esmolol 0.5 mg/kg and lidocaine 1.5 mg/kg. Agitation was measured using the objective pain score, Cole 5-point score, and Richmond Agitation Sedation Scale score at the end of surgery, on arrival in the recovery room, and 10 and 30 min after arrival. Results: The group that received the combination of esmolol and lidocaine showed lower OPS and RASS scores than the other two groups when patients awoke from anesthesia (OPS = 0 (0–4), RASS = –4 [(–5)–1]) and were transferred to the recovery room (OPS = 0 (0–8), RASS = –1 [(–5)–3]) (P < 0.05). There was no significant difference in the severity of agitation among the three groups at other time points (P > 0.05). Conclusions: When pediatric strabismus surgery is accompanied by sevoflurane anesthesia, an intravenous injection of esmolol and lidocaine could alleviate agitation until arrival in the recovery room.

Abstract
Background Postoperative sore throat occurs frequently in surgical patients as a result of tracheal intubation. Despite advances in medical and anaesthetic care, the incidence of postoperative sore throat remains high. Our study aimed to assess the efficacy of acupuncture in the prevention of postoperative sore throat following general anaesthesia. Methods A non-randomised clinical study (NRS) was carried out in a tertiary care hospital in Tehran, Iran on 228 consecutive patients undergoing elective surgeries under general anaesthesia. Of these, 114 patients were assigned to the acupuncture group and treated with body acupuncture at the PC6 point, while the remaining 114 patients received no preventive care and were treated with routine medical treatment where necessary. The incidence of sore throat within the first 24 h postoperatively was then compared between the two study groups. Results Of the 114 patients in the acupuncture group, 16 patients (14%) experienced sore throat within the first 24 h postoperatively, which was significantly lower compared to the 34 patients (29.8%) with sore throat in the medical treatment group (p<0.05). However, the frequency of patients with severe sore throat requiring medical treatment did not differ significantly (12.3% vs 16.7%, p>0.05). Conclusions Our study suggests that acupuncture could be considered as an option in prevention of postoperative anaesthesia-related sore throat.

Abstract
BACKGROUND Postoperative sore throat (POST) following general anesthesia with endotracheal intubation is a common complication. We hypothesized that lidocaine jelly applied to the tapered cuff of the endotracheal tube (ETT) might decrease the incidence of POST most commonly arising from endotracheal intubation. METHODS A total of 208 patients under general anesthesia were randomly assigned into 1 of 2 groups. In the lidocaine group (n = 104), the distal part of ETTs with tapered-shaped cuff was lubricated with lidocaine jelly. In the control group (n = 104), the distal part of ETTs with tapered-shaped cuff was lubricated with normal saline. The incidence of POST, hoarseness, and cough in the postanesthesia patients was compared. RESULTS The overall incidence of POST was higher in the lidocaine group than in the normal saline group [60 (58%) vs 40 (39%), P = .006]. The incidence of POST at 1 hour postoperatively was higher in the lidocaine group than in the normal saline group [53 (51%) vs 32 (31%), P = .003]. The overall incidence of hoarseness for 24 hours postoperatively was comparable (P = .487). The overall incidence of cough for 24 hours postoperatively is higher in the lidocaine group (P = .045). CONCLUSION The lidocaine jelly applied at the distal part of ETT with tapered-shaped cuff increased the overall incidence of POST in patients undergoing general anesthesia.

Abstract
Introduction Postoperative sore throat is listed from the top as patients’ most undesirable outcome in the postoperative period. It is believed to originate from mucosal dehydration or edema, tracheal ischemia secondary to the pressure of endotracheal tube cuffs, aggressive oropharyngeal suctioning, and mucosal erosion from friction between delicate tissues and the endotracheal tube. Even if the problem was indicated in many literatures, it has never been studied in our country. The study aimed to assess prevalence and factors associated with postoperative sore throat among patients who were operated under general anesthesia with endotracheal intubation. Methods Hospital based cross sectional study was conducted from February 25 - April 10, 2014 in Gondar University hospital. Patient interview and chart review were employed for data collection. Bivariate and multivariate logistic regressions were used to determine the association. Results A total of 240 out of 299 patients were included in this study with a response rate of 80.3%. The prevalence of postoperative sore throat within 48 hours after operation was 59.6%. Factors which had association with postoperative sore throat from the multivariate logistic regression were female sex (AOR = 3.3, 95% CI: 1.07, 10.375), repeated number of attempts to intubate (AOR = 3.291, 95% CI: 1.658, 6.531), and the use of nasogastric tube (AOR = 0.41, 95% CI: 0.174, 0.965) respectively. Conclusion The prevalence of postoperative sore throat was high in Gondar University Hospital. Awareness creation about the problem should be made for health professionals and postoperative sore throat management protocol need to be introduced.

Abstract
OBJECTIVE Mechanical ventilation is frequently necessary, in which case the use of an
endotracheal tube is mandatory. The tube has an inflatable balloon in its
distal extremity, whose aim is, among other functions, an efficient
arterialization. However, serious injuries in the place of contact of the
balloon with the trachea can be frequent. Some studies point out that
balloons with permanent pressure may reduce this complication. Nevertheless,
air scape, expressed by the inspiratory (IV) and expiratory volume (EV)
variation (Δ IV-EV), may occur, possibly leading to hypoxemia. Thus,
the goal of this study was to verify the efficiency of a modified
endotracheal tube on arterializations compared to the traditional
endotracheal tube. METHODS The modified endotracheal tube presents intermittent insufflation, with three
drillings in the internal region of the cuff, allowing for insufflation in
the inspiratory phase of the mechanical ventilation. Three animals were used
for the control group, with a cuff pressure of 30 cmH2O, and
seven pigs had the modified endotracheal tube. Each animal was kept under
mechanical ventilation (FIO2=0.21) for 6 hours. Arterial and
venous gases were measured every three hours (T0; T3;
T6). RESULTS The gases confirmed the lack of hypoxia between the Groups, with a difference
in the ΔIV-EV at T0 (P=0.0486). CONCLUSIONS In this study, the lack of hypoxia showed the efficiency of the modified
endotracheal tube. However, new studies are necessary, particularly in
diseased lungs, in order to evaluate the real efficiency of the mentioned
device on the pulmonary gas exchange.

Abstract
BACKGROUND Postoperative sore throat and other airway morbidities are common and troublesome after endotracheal tube intubation general anesthesia (ETGA). We propose lidocaine as endotracheal tube (ETT) cuff inflation media to reduce the postintubation-related emergence phenomenon. METHODS We searched PubMed, EMBASE, and Cochrane databases systematically for randomized controlled trials (RCTs) that have investigated the outcome of intracuff lidocaine versus air or saline in patients receiving ETGA. Using a random-effects model, we conducted a meta-analysis to assess the relative risks (RRs) and mean difference (MD) of the incidence and intensity of relevant adverse outcomes. RESULTS We reviewed nineteen trials, which comprised 1566 patients. The incidence of early- and late-phase postoperative sore throat (POST), coughing, agitation, hoarseness, and dysphonia decreased significantly in lidocaine groups, with RRs of 0.46 (95% confidence interval [CI]: 0.31 to 0.68), 0.41 (95% CI: 0.25 to 0.66), 0.43 (95% CI: 0.31 to 0.62), 0.37 (95% CI: 0.25 to 0.55), 0.43 (95% CI: 0.29 to 0.63), and 0.19 (95% CI: 0.08 to 0.5), respectively, when compared with the control groups. The severity of POST also reduced significantly (mean difference [MD] -16.43 mm, 95% CI: -21.48 to -11.38) at 1 h and (MD -10.22 mm, 95% CI: -13.5 to -6.94) at 24 h. Both alkalinized and non-alkalinized lidocaine in the subgroup analyses showed significant benefits in emergence phenomena prevention compared with the control. CONCLUSION Our results indicate that both alkalinized and non-alkalinized intracuff lidocaine may prevent and alleviate POST and postintubation-related emergence phenomena.

Abstract
BACKGROUND Sore throat is a common side-effect of general anaesthesia and is reported by between 30% and 70% of patients after tracheal intubation. The likelihood of a sore throat varies with the type, diameter, and cuff pressure of the endotracheal tube used. If intubation is essential, it may be helpful to give drugs prophylactically to alleviate postoperative sore throat. Local anaesthetics and steroids have been used for this purpose. This review was originally published in 2009 and was updated in 2015. OBJECTIVES The objective of this review was to evaluate the efficacy and any harm caused by topical and systemic lidocaine used prophylactically to prevent postoperative sore throat in adults undergoing general anaesthesia with endotracheal intubation. SEARCH METHODS We searched CENTRAL (The Cochrane Library 2013, Issue 9), MEDLINE (January 1966 to October 2013), and EMBASE (1980 to October 2013). We also contacted manufacturers and researchers in the field. The original search was undertaken in June 2007. We reran the search in February 2015 and found four studies of interest. We will deal with those studies when we next update the review. SELECTION CRITERIA We included randomized controlled trials (RCTs) of topical and systemic prophylactic lidocaine therapy versus control (using air or saline) that reported on the risk and severity of postoperative sore throat as an outcome. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. We contacted study authors for additional information, such as the risk of any adverse effects. MAIN RESULTS We included 19 studies involving 1940 participants in this updated review. Of those 1940 participants, 952 received topical or systemic lidocaine therapy and 795 were allocated to the control groups. Topical and systemic lidocaine therapy appeared to reduce the risk of postoperative sore throat (16 studies, 1774 participants, risk ratio (RR) was 0.64 (95% confidence interval (CI) 0.48 to 0.85), the quality of the evidence was low), although when only high-quality trials were included (eight studies, 814 participants) the effect was no longer significant (RR 0.71, 95% CI 0.47 to 1.09). Lidocaine given systemically in two studies (320 participants) did not reveal evidence of an effect (RR 0.44, 95% CI 0.19 to 1.05 ). The severity of sore throat as measured on a visual-analogue scale (VAS) was reduced by lidocaine therapy (six trials, 611 participants, (mean difference (MD) -10.80, 95% CI -14.63 to -6.98). The adverse effects of lidocaine were not reported in these studies, though toxicity is generally rare. AUTHORS' CONCLUSIONS In our revised systematic review, although the results of included studies show generally positive results, they should be interpreted carefully. The effect size of lidocaine appeared to be affected by study quality; drug concentration; route of administration; management of cuff pressure during anaesthesia; the included population; and the type of outcome measured.

Abstract
BACKGROUND Postoperative sore throat is a common complication of endotracheal intubation and can lead to dissatisfaction after surgery. Airway management has the strongest influence on the incidence of sore throat and improving endotracheal intubating conditions can reduce this complaint. Type of induction agent used during anesthesia can contribute to variances in the degree of post-operative sore throat. OBJECTIVES We aimed to compare the incidence of postoperative sore throat after rapid sequence induction with Succinylcholine and high dose Cisatracurium. PATIENTS AND METHODS The study was carried out on patients admitted to Shohada-e-Tajrish hospital for emergent abdominal surgery. Of the 80 patients who were enrolled in the study, 40 were randomly assigned to receive Succinylcholine while the remaining patients received Cistracurium during induction. Sore throat, muscle ache, hoarseness, dry throat and pain were assessed in each patient at baseline in recovery and at 2, 4, 12 and 24 hours post-operation. RESULTS Number of patients who developed sore throat was significantly higher in the Succinylcholine group (75%) compared to Cisatracurium group (27.5%) at the time of entrance to the recovery room (P = 0.001). These numbers decreased at 2 hours post-operation (42% versus 17.5%) but the difference was still statistically significant (P < 0.05). At 12 (P = 0.062) and 24 (P = 0.14) hours post operation, the difference was no longer significant. CONCLUSIONS Use of high dose Cisatracurium for induction during rapid sequence intubation carries a lower chance of developing sore throat compared to Succinylcholine. Studies comparing other adverse effects of these two agents are required to guide physician's choice of induction agent.

Abstract
OBJECTIVES Endotracheal tube (ETT) and its inflated cuff are likely to induce specific reactivity at the emergence time. In ICU, the tolerance of the ETT cuff could be a part of patient agitation and increased of sedation. MATERIALS AND METHODS Using specific ICU ETT cuff (thin polyurethane cuff), we perform an in vitro evaluation of diffusion of lidocaine and alkalinized lidocaine (L-B) across the PU cuff for a long duration. We evaluate the safety of this procedure by a daily injection into the cuff. RESULTS With lidocaine alone, we observed a low rate of diffusion through the cuff (<8% over 24h), whereas the L-B solution had a high diffusion (>90% over 24h). The released profiles were similar from day 0 to day 8, and no cuff rupture was reported over the 8-day study. CONCLUSION The safety, controlled release, and lack of deleterious effects on cuff membrane were confirmed. In case of unexpected cuff rupture, an adequate determination of the mixture allows to obtain a safe solution with the achievement of a physiological pH (7.4) and the small dose of lidocaine (40 mg).

Abstract
BACKGROUND Postoperative sore throat (POST) is a common complication following tracheal intubation. The effectiveness of prophylactic dexamethasone on POST needs further elucidation. AIMS To evaluate the effectiveness and safety of intravenous dexamethasone for the prevention of POST in patients undergoing endotracheal intubation. METHODS Studies were identified by literature searches of PubMed, Embase, and the Cochrane database. Systematic review was performed by two independent investigators. RESULTS We summarized 7 RCTs including 727 participants. Intravenous dexamethasone significantly reduced the risk of POST at 24 h [pooled risk ratio (RR) = 0.676; 95 % confidence interval (CI) 0.494-0.925; P = 0.014; heterogeneity test, I (2) = 45.8 %], as well as alleviating its severity [standardized mean difference (SMD) = -1.15; 95 % CI -1.86 to -0.45; P = 0.002; heterogeneity test, I (2) = 91.7 %]. Further sub-group analysis indicated a significant relationship between dexamethasone and reduced risk of POST when its dose was over 0.1 mg/kg. No severe adverse effects were reported. CONCLUSIONS Our results suggest that intravenous dexamethasone reduces the risk and severity of POST from intubation at 24 h. The effective dosage of dexamethasone for preventing the risk of POST appeared to be over 0.1 mg/kg.

Abstract
BACKGROUND Postoperative sore throat is one of the most common complications of general anesthesia and intubation with prevalence of 18%-65% in different studies. Several risk factors including female gender, postoperative nausea and vomiting and so on have been mentioned. OBJECTIVES The aim of this study was to evaluate the incidence of postoperative sore throat in females and its association with menstrual cycles. PATIENTS AND METHODS One hundred females between 18-45 years old with ASA class I or II without predicted difficult airway that were candidate for operation in supine position were enrolled in study. Patients who had pulmonary disease, smoking, common cold within two weeks prior to the operation, previous traumatic intubation history, removable dentures, any congenital or acquired deformity in face, neck, mouth and airway, any known pathology in mouth like aphthous and mouth ulcer,pregnant women, and patients with irregular cycles, and those taking oral contraceptive pills were excluded. By the same protocol general anesthesia was provided and the patients were asked to fill out a three-point scale questionnaire (Low, High, None) 1,6 and 24 hours following intubation to study and record the incidence and severity of sore throat, dysphagia and hoarseness. The date of last menstrual period had been recorded as well. RESULTS Of 100 patients, in the first six hours, 51 patients had sore throat and 49 had no pain. During the first 6 hours, 33 patients (33%) had dysphagia and 13 patients had hoarseness at 6th postoperative hour. Age, weight, LMP, intubation time, operation and extubation time and coughing were compared to sore throat, dysphagia and hoarseness. The association between the incidence of coughing and bucking and sore throat was significant (P = 0.03). None of the parameters had a statistically meaningful association with dysphagia. CONCLUSIONS According to our results, by omitting probable risk factors of incidence of sore throat and evaluation of role of hormonal changes in women represented in menstrual cycles, there was no significant association between menstrual cycle and sore throat incidence.

The effects of lidocaine spray and intracuff alkalinized lidocaine on the occurrence of cough at extubation: a double-blind randomized controlled trial. Can J Anaesth 2013; 60:370-6. [PMID: 23370978 DOI: 10.1007/s12630-013-9896-8] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2012] [Accepted: 12/13/2012] [Indexed: 01/25/2023] Open
Abstract
PURPOSE Our study aimed to evaluate the effects of lidocaine sprayed onto the larynx and/or injected into the tracheal tube cuff to decrease the incidence of cough at extubation and postoperative sore throat. METHODS One hundred twenty women scheduled for gynecological surgery < 120 min in duration were enrolled in this randomized double-blind prospective study. Prior to tracheal intubation, 4% lidocaine or 0.9% saline was sprayed onto the patients' supra- and subglottic areas. After tracheal intubation, the tracheal tube cuff was filled with either an alkalinized 2% lidocaine solution or 0.9% saline. This resulted in four groups: spray-cuff, spray-saline, saline-cuff, and saline-saline. A logistic regression comprising the two factors was used for analysis. The primary outcome was the incidence of cough at extubation. The secondary outcome was the incidence and severity of sore throat reported by patients at 15 min, 60 min, and 24 hr after tracheal extubation. RESULTS Cough occurred in 42%, 24%, 63%, and 69% of patients in the spray-cuff, spray-saline, saline-cuff, and saline-saline groups, respectively. The use of lidocaine spray decreased the incidence of cough at extubation (odds ratio = 0.256; 95% confidence interval 0.118 to 0.554; P < 0.001); however, the use of intracuff alkalinized lidocaine had no impact on the occurrence of cough (P = 0.471). Severity of sore throat was clinically low (visual analog scale [VAS] ≤ 3) in all groups. No significant difference was observed in hoarseness, dysphagia, nausea, or vomiting. CONCLUSION Sprayed lidocaine decreases the incidence of cough at tracheal extubation in surgeries of less than two hours. The use of alkalinized lidocaine into high-volume/low-pressure endotracheal cuffs had no impact on decreasing the incidence of cough or pain.

Endotracheal tube cuff lidocaine is not superior to intravenous lidocaine in short pediatric surgeries. Int J Pediatr Otorhinolaryngol 2010; 74:486-8.

Abstract
BACKGROUND Instillation of lidocaine into the endotracheal tube cuff is a method with reported efficiency in promoting a smoother emergence from anesthesia with endotracheal intubation. However, whether or not this method is helpful in children and in surgeries with short duration has not been investigated previously. METHODS 176 ASA I-II children undergoing adenotonsillectomy were enrolled in this prospective, double-blind, randomized clinical trial. Patients were randomly allocated to two groups. Patients in the ECL group (n=88) were injected 2% lidocaine into their endotracheal tube cuff and received saline (1.5mg/kg) intravenously. The IVL group (n=88) received 1.5mg/kg of 2% lidocaine intravenously and saline into the endotracheal tube cuff. In both groups, intra-cuff injections were initiated immediately after insertion of the endotracheal tube and terminated before the cuff pressure reached 20 cmH(2)O. The parameters measured were: coughing (graded by a scale of 3 at the time of extubation), systolic and diastolic blood pressures and heart rate (from the time of extubation up to 5 min after extubation at 1-min intervals), and laryngospasm (defined as the presence of hoarseness or absence of airflow). RESULTS The groups were not different in sex, age, weight, height, body mass index, anesthesia duration, and baseline hemodynamic parameters. The grade of coughing was significantly higher in the ECL group. The incidence of laryngospasm and hemodynamic trends did not differ between the groups. CONCLUSIONS Our results indicate that intra-cuff lidocaine may not be beneficial in children and in surgeries with a short duration.

Abstract
BACKGROUND AND OBJECTIVE We wished to examine the efficacy of different media used for inflation of tracheal tube cuffs. METHODS In our prospective randomized, controlled study over 3 months, there were 150 patients of either sex undergoing surgery under general anaesthesia with controlled ventilation with nitrous oxide and oxygen. The patients were divided into three equal groups (air, isotonic saline and alkalinized lignocaine as inflation media) using sealed envelope technique. The volume of the inflation medium, intracuff pressure, duration of intubation, volume of the inflation medium withdrawn from the cuff and complications like tube intolerance, coughing on tube, restlessness, hoarseness, sore throat, breathlessness and laryngospasm were analysed. Continuous data are presented as mean +/- SD, whereas categorical data are presented as frequencies and percentages. A [chi]2, analysis of variance and student's t-test were used to analyse the data. A P value less than 0.05 was considered as statistically significant. RESULTS Age, sex, duration of intubation, intracuff pressure at the time of intubation were comparable. After intubation at all intervals, the intracuff pressure was higher in the air group with statistical significance at 5 min, 30 min, 1 h and just before extubation when air and saline groups were comparable and at all intervals after intubation up to just before extubation when air and lignocaine groups were comparable. The volume of air increased just before extubation in the air group, as compared with a fall in volume in the other groups. Tube intolerance, hoarseness and sore throat were least in the lignocaine group. CONCLUSION We found that alkalinized 2% lignocaine and saline are better cuff inflation media, than air.

Abstract
BACKGROUND Sore throat is a common side effect of general anaesthesia and is reported by between 30% and 70% of patients after tracheal intubation. The likelihood of a sore throat varies with the type, diameter, and cuff pressure of the endotracheal tube used. If intubation is essential, it may be helpful to give drugs prophylactically to alleviate postoperative sore throat. Local anaesthetics and steroids have been used for this purpose. OBJECTIVES The objective of this review was to evaluate the effectiveness and any harms of topical and systematic lidocaine for the prevention of postoperative sore throat in adults undergoing endotracheal intubation as part of general anaesthesia. SEARCH STRATEGY We searched CENTRAL (The Cochrane Library 2007, Issue 3), MEDLINE (January 1966 to June 2007), and EMBASE (1980 to June 2007). We also contacted manufacturers and researchers in the field. SELECTION CRITERIA We included randomized controlled trials of topical and systemic prophylactic lidocaine therapy versus control (using air or saline) that reported on the risk and severity of postoperative sore throat as an outcome. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. We contacted study authors for additional information, such as the risk of adverse effects. MAIN RESULTS We included 1232 patients from 15 studies; 672 patients received topical or systemic lidocaine therapy and 560 patients were allocated to the control group. Both the topical and systemic lidocaine therapy significantly reduced the risk of postoperative sore throat (risk ratio (RR) 0.58; 95% confidence interval (CI) 0.41 to 0.82). To evaluate the severity of sore throat on a visual analogue scale (VAS), 219 patients received topical or systemic lidocaine therapy and 152 patients were allocated to the control groups. The severity of sore throat was reduced (mean difference (MD) -11.9; 95% CI -16.44 to -7.32), an effect that neared statistical significance. The adverse effects of lidocaine were not reported in these studies. AUTHORS' CONCLUSIONS Our systematic review establishes the effectiveness of topical and systemic lidocaine for the prevention of postoperative sore throat resulting from intubation. The risk and severity of postoperative sore throat tended to be reduced. The effect size of lidocaine appeared to be affected by drug concentration and route of administration; management of cuff pressure during anaesthesia; the included population; and the type of outcome measured.

Abstract
CONTEXT AND OBJECTIVE High intracuff pressure in endotracheal tubes (ETs) may cause tracheal lesions. The aim of this study was to evaluate the effectiveness and safety of endotracheal tube cuffs filled with air or with alkalinized lidocaine. DESIGN AND SETTING This was a prospective clinical study at the Department of Anesthesiology, Faculdade de Medicina de Botucatu, Universidade Estadual Paulista. METHODS Among 50 patients, ET cuff pressures were recorded before, 30, 60, 90 and 120 minutes after starting and upon ending nitrous oxide anesthesia. The patients were randomly allocated to two groups: Air, with ET cuff inflated with air to attain a cuff pressure of 20 cmH2O; and Lido, with ET cuff filled with 2% lidocaine plus 8.4% sodium bicarbonate to attain the same pressure. ET discomfort before tracheal extubation, and sore throat, hoarseness and coughing incidence were studied at the time of discharge from the post-anesthesia care unit, and sore throat and hoarseness were studied 24 hours after anesthesia. RESULTS Pressures in Lido cuffs were significantly lower than in Air cuffs (p < 0.05). Tracheal complaints were similar for the two groups, except for lower ET discomfort and sore throat incidence after 24 hours and lower systolic arterial pressure at the time of extubation in the Lido group (p < 0.05). CONCLUSION ET cuffs filled with alkalinized lidocaine prevented the occurrence of high cuff pressures during N2O anesthesia and reduced ET discomfort and postoperative sore throat incidence. Thus, alkalinized lidocaine-filled ET cuffs seem to be safer than conventional air-filled ET cuffs.

Abstract
BACKGROUND In this study, we aimed to compare the effectiveness of dexpanthenol pastille and benzydamine hydrochloride spray on the prevention of a sore throat. METHODS One hundred and eighty patients undergoing general anaesthesia, who were ASA I-II and with their ages ranging between 15 and 70 years, were randomly allocated to three groups, each consisting of 60 patients. For group B, four puffs of benzydamine hydrochloride were sprayed into the mouth initially 30 min before the operation and repeatedly 5 min before anaesthesia induction. For group D, two pastilles of dexpanthenol were administered orally to be sucked 30 min before the operation. For group P, four puffs of distilled water were sprayed into the mouth initially 30 min before the operation. Post-operatively, patients were evaluated for a sore throat for the duration of 24 h. RESULTS The incidence of a sore throat was significantly lower for group D when compared with group B and group P. The incidence of a sore throat was similar for group B and group P. According to the sore throat grading system, the number of patients experiencing no complaints was significantly higher for group D when compared with group B and group P. The number of patients achieving moderate scores was significantly higher for group B when compared with group D. CONCLUSION The administration of 200 mg of dexpanthenol prophylactically before endotracheal intubation is effective in the prevention of post-operative sore throat.

Abstract
The aim of this study was to evaluate the incidence of coughing and breath holding in patients undergoing lumbar surgery extubated in prone position, supine position, or supine position with intravenous lidocaine before extubation. About 105 ASA I to II patients undergoing lumbar surgery were extubated in prone position in group P (n = 35), in supine position in group S (n = 35) and in supine position with intravenous 1.5 mg/kg lidocaine 10 minutes before extubation in group SL (n = 35). The number of patients who coughed and demonstrated breath holding was noted at emergence period. The time of loss of monitoring while repositioning the patient was recorded. The frequency of cough in group S was higher compared with group P at 1 minute after extubation (P = 0.008). Two and three minutes after extubation, the patients in group S demonstrated higher cough incidence compared with groups P and SL (P < 0.05). The incidence of breath holding in the first 6 minutes was lower in group P (n = 11) compared with groups S (n = 29) and SL (n = 25)(P = 0.001). The loss of monitoring time was longer in groups S (62 +/- 40 s) and SL (53 +/- 39 s) when compared with group P (0 s) (P < 0.01). Prone emergence and supine emergence with intravenous lidocaine provides an alternative approach to conventional supine emergence and prone extubation offers less cough and breath holding and continuation of monitoring.

Abstract
When alkalinized lidocaine instead of air is used to fill the endotracheal tube (ETT) cuff, coughing, and bucking are decreased during extubation when ventilation is controlled with N2O. However, sodium bicarbonate (NaHCO3) used to transform lidocaine hydrochloride (L-HCl) to lidocaine base induces a pH increase that could be irritating for mucosa in the case of cuff rupture. Therefore, we determined, in a randomized controlled study with controlled patient ventilation without N2O, whether the smallest concentrations of NaHCO3 (1.4% versus 8.4%) reduced diffusion (in vitro evaluation) and other secondary clinical benefits. After pH determination of different solutions (2 mL of 2% L-HCl and 2 to 6 mL of 8.4%, or 1.4% NaHCO3), an in vitro lidocaine diffusion through the ETT cuffs was evaluated (2 mL of 2% L-HCl and 3 mL of 8.4% or 1.4% NaHCO3). Then, adult patients scheduled for total thyroidectomy surgery were consecutively enrolled (n = 20 for each group). The ETT cuff was filled with air (group air) or with alkalinized lidocaine (2 mL of 2% L-HCl) using 8.4% (group large dose) or 1.4% (group small dose) of NaHCO3. After tracheal extubation, sore throat was evaluated by visual analog scale as the main end-point of the study. Hoarseness, bucking, dysphonia, dysphagia, cough, restlessness, and postoperative nausea and vomiting were also evaluated. There was a slight tendency toward a slower release when a small concentration of NaHCO3 was used (i.e., 1.4%). Compared with group air, the alkalinized-lidocaine groups had a significant reduction in sore throat during the 24-h postoperative period (P < 0.0001). The difference was not significant between the two alkalinized lidocaine groups. This increase in ETT tolerance was confirmed by the analysis of secondary end-points. No laryngospasm, rupture of ETT cuff, or depression of the swallowing reflex were recorded. A decrease in sore throat during the postoperative period was recorded when the cuff was inflated with a small dose of alkalinized lidocaine (i.e., 40 mg of L-HCl and 1.4% of NaHCO3) rather than with air when ventilation was controlled without N2O.

Abstract
BACKGROUND AND OBJECTIVE Sore throat and hoarseness rank, besides pain and nausea, among the most frequent subjective complaints after tracheal intubation for general anaesthesia. Our intention was to determine the incidence of postoperative sore throat from a large sample of patients and thus to identify the most important associated factors. METHODS We prospectively followed up 809 adult patients who underwent elective surgical interventions and examined their history, the applied anaesthetic techniques, perioperative course and the occurrence, intensity and duration of postoperative throat complaints. The assignment and professional experience of the involved intubators were also assessed. The influence of a multitude of variables on postoperative throat complaints was statistically analysed. RESULTS Postoperative sore throat was present in 40% overall being significantly higher in female than in male (44% vs. 33%; P = 0.001). The mean pain intensity in the affected patients (n = 323) was 28+/-12 mm on a visual analogue scale where 0 = no pain and 100 = extreme pain. The average duration was 16+/-11 h. Main factors associated with throat complaints were female sex; history of smoking or lung disease, duration of anaesthesia, postoperative nausea, bloodstain on the endotracheal tube and natural teeth. We could find no influence on the occurrence or intensity of throat complaints by the professional assignment or the length of professional experience of the personnel involved. CONCLUSIONS Postoperative throat complaints frequently arise after tracheal intubation for general anaesthesia in the first 2 postoperative days, but they are of limited intensity and duration.

Abstract
In a randomised, double-blind, sham-controlled study, we compared the efficacy of capsicum plaster (PAS) applied at the Korean hand acupuncture point for the prevention of postoperative sore throat in 150 patients scheduled to undergo abdominal hysterectomy. The K group had PAS applied at the K-A20 of both hands and placebo tape at both non-acupoints. The PAS was applied prior to induction of anaesthesia and removed 8 h postoperatively. The sore throat scores of Group K were significantly lower than those of other groups at 24 h following surgery (p = 0.00027). The prevalence of moderate to severe sore throat at 24 h was lower for Group K (0%) than for sham and placebo controls (16%[p = 0.038] and 19%[p = 0.032], respectively). There were no differences in the recovery room of the sore throat scores for all groups. We found that the PAS applied at the K-A20 was an alternative method for reducing postoperative sore throat.

Abstract
BACKGROUND We sought to determine the benefits of using alkalinized lidocaine 40 mg to fill the cuff of a tracheal tube (ETT) in combination with water-soluble gel lubrication to prevent post-intubation sore throat. METHODS The work included an in vitro study of the diffusion of alkalinized lidocaine solution through the low-pressure, high-volume cuff of an ETT. We also performed a randomized controlled study (n=20 patients in each group) that included a group who received an alkalinized lidocaine-filled ETT cuff with lubrication of the tube using water-soluble gel (Group G), and two control groups who received an alkalinized lidocaine-filled cuff with ETT lubrication with water (Group W) or an air-filled cuff with ETT lubrication with water (Group C). RESULTS Water-soluble gel lubrication (Group G) produced a lower incidence of sore throat during the 24-h post-extubation period than lubrication with water alone in the cuffs filled with alkalinized lidocaine (Group W), and compared with the air control group. The ability of lidocaine to pass through the cuff of an ETT when water-soluble gel and/or water alone was used as a lubricant was similar, as determined by lidocaine plasma concentrations (C(max) 45 ng x ml(-1)). Cough and restlessness before tracheal extubation were decreased in patients with the alkalinized lidocaine-filled cuffs compared with the air-filled cuffs. After extubation, nausea, vomiting, dysphonia and hoarseness were greater for patients with air-filled cuffs compared with the lidocaine-filled cuffs. No significant difference between the groups was recorded in arterial blood pressure and heart rate. In vitro data suggest that the lower the NaHCO(3) injection volume, the greater the release of lidocaine across a low-pressure, high-volume cuff. CONCLUSIONS These data show benefits of using an alkalinized lidocaine-filled ETT cuff in combination with water-soluble gel lubrication in preventing post-intubation sore throat.

Abstract
OBJECTIVE This prospective observational study was undertaken in order to assess pain experienced by intensive care unit patients at the time of extubation and to identify factors associated with pain of at least moderate intensity. DESIGN Prospective observational study. SETTING Intensive care unit at a university hospital. PATIENTS During a 1-year period the presence, severity and clinical predictors of orofacial and/or chest pain among patients undergoing removal of endotracheal tubes was assessed. MEASUREMENTS AND RESULTS Pain was evaluated using a visual analogue scale (VAS). Of 332 extubated patients, 203 could be evaluated. During the peri-extubation period, pain was significantly associated with a SAPS II score more than 36 ( p=0.03) and duration of mechanical ventilation (MV) of 6 days or more ( p=0.002), whereas intubation in the operating room was associated with less pain ( p=0.001). Pain of at least moderate intensity (VAS score >30 mm) was reported by 73% of patients and pain of severe intensity (VAS score >50 mm) was reported by 45% of patients. MV duration of 6 days or more was the only independent risk factor for pain of at least moderate intensity (OR 2.4, 95% CI 1.03-5.4, p=0.04). We also observed that pain had resolved 1 h after extubation in the majority of patients. CONCLUSION Our results suggest that, in intensive care unit patients, peri-extubation pain is frequent and should be considered for treatment, especially in patients with longer intubation.

Abstract
OBJECTIVE We assessed the efficacy of topical methylprednisolone or lidocaine for prevention of postoperative sore throat. STUDY DESIGN Randomised, prospective in single blind study. PATIENTS AND METHODS Sixty patients ASA 1 or 2 undergoing tracheal intubation for dental surgery received before intubation either topical lidocaine 5% (15 puffs) or aerosolized methylprednisolone (80 mg). Postoperative pain was assessed by the patients using a VAS and a specific scoring system for sore throat, cough and hoarseness. Evaluations were performed immediately after emergence from anaesthesia, 1 h later, at time of the first postoperative drink, at time of the first postoperative meal and 24 h after surgery. RESULTS Patients receiving methylprednisolone showed slightly better scores for sore throat and cough 1 h after surgery. CONCLUSION Topical methylprednisolone may therefore be a useful adjuvant in the prevention of sore throat after intubation.

Abstract
STUDY OBJECTIVE To evaluate the efficacy of various ways of lidocaine application in reducing postoperative cough and sore throat. DESIGN Double-blind, randomized study. SETTING University-affiliated hospital. PATIENTS 204 ASA physical status I and II patients scheduled for cataract surgery with general anesthesia. INTERVENTIONS Patients were randomized to six groups (G1, G2, G3, G4, G5, and G6), according to lidocaine application method. Before endotracheal intubation, in the G1 and G2 groups, 10% lidocaine was sprayed on the distal end of the endotracheal tubes (ETTs; G1) and laryngopharyngeal structures (G2). In the G3 group, the distal ends of the ETTs were lubricated with 2% lidocaine jelly. Intravenous (IV) lidocaine was administered to the G4 group at the conclusion of surgery. Intracuff lidocaine was used in the G5 group; in the G6 group, the terminal end of the ETTs were lubricated with normal saline. MEASUREMENTS At the end of surgery and after extubation, patients were observed to record the number of coughs. At 1 hour and at 24 hours following extubation, sore throat was evaluated. MAIN RESULTS In the recovery room, 64.4% of the patients experienced cough, with greatest frequency in the G3, G6, and G2 groups, and the least in the G5 and G4 groups. The frequency of sore throat was significantly different among the six groups at 1 hour and at 24 hours, with greater frequency in the G3, G2, and G6 groups. CONCLUSIONS Using lidocaine to inflate the ETT cuff or IV lidocaine at the end of surgery decreases the frequency of postoperative cough and sore throat and would provide better outcome for patients and the physician.

Abstract
UNLABELLED We sought to evaluate the effect of filling an endotracheal tube cuff with 40 mg lidocaine alone (Group L) or alkalinized lidocaine (Group LB) in comparison to an Air Control group (Group C) on adverse emergence phenomena in a randomized controlled study (n = 25 in each group). The incidence of sore throat was decreased for Group LB in comparison to Group L during the 24 postextubation hours. The difference between Group L and Group C remained significant in the two postextubation hours only. Plasma lidocaine levels increased when lidocaine was alkalinized (C(max) were 62.5 +/- 34.0 ng/mL and 3.2 +/- 1.0 ng/mL for Groups LB and L, respectively). Cough and restlessness before tracheal extubation were decreased in Group LB compared with Group L and in Group L compared with Group C. Nausea, postoperative vomiting, dysphonia, and hoarseness were increased after extubation in Group C compared with the liquid groups, and a better tolerance was recorded with Group LB compared with Group L. The increase of arterial blood pressure and cardiac frequencies during the extubation period was less in the liquid groups than in the control group and less in Group LB compared with Group L. We concluded that use of intracuff alkalinized lidocaine is an effective adjunct to endotracheal intubation. IMPLICATIONS Use of 40 mg of alkalinized lidocaine, rather than lidocaine or air, to fill the endotracheal tube cuff reduces the incidence of sore throat in the postoperative period. This approach also decreases hemodynamic effects, restlessness, dysphonia, and hoarseness.

Abstract
BACKGROUND Sore throat is not an uncommon complaint following general anaesthesia (GA) with endotracheal intubation. It has been a source of considerable discomfort particularly in those patients who had thyroid surgery. Driven by the increased number of patients with post-intubation sore throat following thyroid surgery, the aim of the present study was to evaluate the contributing factors of sore throat in patients who had thyroid surgery under general anaesthesia. METHODS A total of 57 consecutive patients who had thyroid surgery from November 1998 to April 1999 was included in this prospective study. Factors such as intubation time, number of intubation attempts, size and type of endotracheal tube (ETT) used, gender and age were recorded. The nature and extent of the surgical procedures were also studied. Postoperative symptoms were assessed by questionnaire on the day after surgery and the different parameters were compared and analysed. RESULTS The incidence of post-intubation sore throat following thyroid surgery was documented in 39 (68.4%) patients. Twenty-seven (47.4%) patients had a mild complaint of sore throat, which resolved after the third day. The data from the present study show that the size of ETT and extent of surgical procedure were significant contributing factors affecting the postoperative recovery. CONCLUSION The outcome of the present study demonstrated a substantial increased incidence of sore throat after thyroid surgery under GA. Postoperative sore throat following thyroid surgery under GA may be caused by multiple contributing factors. Nonetheless effort and care should be taken during endotracheal intubation and surgery to reduce this unpleasant complaint arising mainly from pharyngeal irritation or trauma.

Abstract
The purpose of this study was to examine if lidocaine diffusion across an endotracheal tube cuff could improve post-operative tolerance, especially sore throat. The in vitro release of lidocaine from tube cuffs filled with different lidocaine formulations (base form, hydrochloride form or alkalinized lidocaine hydrochloride) was investigated. A preliminary pilot clinical study in anaesthesia for spine surgery in smoker patients was carried out to examine the pharmacokinetic (i.e. systemic uptake) and pharmacodynamic effects (i.e. incidence of sore throat) obtained with the endotracheal tube cuff filled with lidocaine solution, compared to cuffs inflated only with air. From our in vitro experiment, only the hydrophobic neutral base form of lidocaine was able to diffuse (65.1+/-1.1% released after 6 h), while for the charged hydrochloride form, only a permeation phenomenon occurred concerning only 1% of the total drug. Alkalinization of lidocaine hydrochloride (the only form available as a drug) allows smaller amounts to be used compared to previous published studies (20-40 mg vs. 200-500 mg) and no lag time for diffusion. Such a system could provide a controlled release reservoir for lidocaine to adjacent tracheal tissue. This was shown in our pilot study with sustained plasmatic profiles and improved tolerance (decreased pain scores) in the rank order: air group<<lidocaine hydrochloride group<alkalinized lidocaine group.

Abstract
The purpose of this study was to evaluate the effects (common haemodynamic variables, peak cuff pressures, the incidence of reaction ('bucking') during extubation and the incidence of sore throat after operation) of lidocaine 10% instilled into the endotracheal tube cuff in intubated patients. Plasma concentrations of lidocaine were assayed. Seventy ASA class I-II patients scheduled for plastic surgery were studied. Patients were randomly divided in two groups: the cuff of the endotracheal tube was inflated with either lidocaine 10% (group L) or with saline (group S) immediately after endotracheal intubation. In group L patients, the haemodynamic changes were less (P < 0.05), and the peak cuff pressure was lower (P < 0.01) than for group S. At extubation, more patients reacted ('bucked') in group S (70.5% vs. 19.4%, P < 0.01). The incidence and severity of sore throat were significantly lower in group L 1 and 24-h after extubation. Plasma lidocaine concentrations did not reach toxic values. Lidocaine 10%, compared with saline, in the endotracheal tube cuff was associated with less disturbance of haemodynamic responses and less incidence of bucking during tracheal extubation. Lidocaine was also effective in reducing of incidence and severity of sore throat after operation.

Abstract
PURPOSE To examine whether lidocaine diffusion across an endotracheal tube cuff affects tracheostomy tube discomfort. METHODS Two tracheostomy tube cuffs were inflated with 5 ml lidocaine 4% solution and air at 20 cmH2O, and then placed in 20 ml distilled water at 37 degrees C. After vigorous stirring, 100 microl of this water was then sampled immediately then 1, 2, 4, 8, 24 hr later to measure lidocaine concentration by high-performance liquid chromatography. Sixteen patients undergoing tracheostomy following oral cancer resection were randomly assigned to two groups: lidocaine (n=8) and placebo (n=8). A tracheostomy tube cuff was inflated with 5 ml lidocaine 4% or saline 0.9% and air to a cuff pressure of 20 cmH2O, in the lidocaine and placebo groups respectively. Tube discomfort was evaluated using a visual analogue scale at 0, 0.5, 1, 2 and 4 hr after lidocaine or saline administration. Neither analgesics nor sedatives was given during the evaluation period. RESULTS Lidocaine time-dependently diffused across the tracheostomy tube cuff. Thirty and 60 min after cuff inflation lidocaine concentrations in the water bath reached approximately 8 and 17 microg x ml(-1) representing 160 and 340 microg in 20 ml of water, respectively. The VAS decreased from 53.5 +/- 10.6 to 25.1 +/- 9.8 mm (P < 0.01) 0.5 hr following lidocaine administration which continued until the end of evaluation period. In the placebo group, VAS did not change. CONCLUSION Lidocaine diffusion across the tracheostomy tube cuff reduces tube discomfort.
