Wallen SL, Paul TV, Tubog TD. Intracuff Lidocaine and Postoperative Throat Mucosal Injuries: An Evidence-based Review. J Perianesth Nurs 2024:S1089-9472(24)00099-6. [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.

Emergence characteristics comparing endotracheal tube to reinforced laryngeal mask airway during endoscopic sinus surgery - A randomised controlled study. Indian J Anaesth 2024; 68:460-466. [PMID: 38764963 PMCID: PMC11100652 DOI: 10.4103/ija.ija_966_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 03/05/2024] [Accepted: 03/06/2024] [Indexed: 05/21/2024] Open
Abstract
Background and Aims During endoscopic sinus surgery, anaesthetic conditions significantly impact the intraoperative surgical field and bleeding during emergence. While the endotracheal tube (ETT) has been traditionally used in sinus surgery, a reinforced laryngeal mask airway (RLMA) that produces less upper airway stimulation may result in smoother emergence. Methods A randomised controlled trial of 72 patients undergoing elective sinus surgery was conducted, with the allocation of airway technique to either ETT with a throat pack or RLMA. The primary outcome measure was emergence time, measured by time to opening eyes on commands at the cessation of anaesthesia, and the secondary outcomes were time to removal of airway device, remifentanil use, procedure times, mean arterial pressure (MAP) and the RLMA grade of blood contamination. The continuous variables were analysed using Student's t-tests and discrete variables, count tables were analysed using Fisher's exact tests. Results There was no significant difference in the emergence time between the ETT and RLMA groups (P = 0.83). Remifentanil use was significantly higher in the ETT group than in the RLMA group (P = 0.022). The ETT group showed a significantly increased total anaesthetic time (P = 0.01). MAP was not significant during preinduction, maintenance or post-RMLA removal. The highest grade of contamination was grade 2 in RLMA. RLMA had lower rates of postoperative adverse events. Conclusions RLMA comparable to ETT in terms of emergence time. The RMLA group had lower remifentanil use, anaesthesia duration and fewer postoperative adverse events such as cough and throat pain.

Laryngeal mask airway versus endotracheal intubation as general anesthesia airway managements for atrial fibrillation catheter ablation: a comparative analysis based on propensity score matching. J Interv Card Electrophysiol 2024:10.1007/s10840-024-01742-w. [PMID: 38225533 DOI: 10.1007/s10840-024-01742-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 01/07/2024] [Indexed: 01/17/2024]
Abstract
BACKGROUND The current evidence on the use of laryngeal mask airway (LMA) as an airway management technique for general anesthesia (GA) during atrial fibrillation (AF) catheter ablation (CA) is insufficient. This study aims to compare the feasibility, safety, and clinical benefits of LMA and endotracheal intubation (ETI) for airway management in AF CA. METHODS One hundred fifty-two consecutive patients with AF who underwent CA under GA were included and divided into two groups based on different airway management methods (66 in the LMA group, 86 in the ETI group). After propensity score matching, a final analysis cohort of 132 patients was obtained to compare procedural parameters, adverse events, and prognosis between the two groups. RESULTS The LMA group exhibited significantly shorter total procedural time (p = 0.039), anesthesia induction time (p = 0.015), and recovery time (p = 0.006) compared to the ETI group. The mean arterial pressure (MAP) and heart rate were significantly lower in the LMA group during extubation and 1-min post-extubation (p < 0.05). Furthermore, the LMA group demonstrated lower MAP levels during intubation (p = 0.029). The incidences of intraoperative hypotension (p = 0.017) and bradycardia (p = 0.032) were significantly lower in the LMA group. The incidences of delayed recovery or delirium (p = 0.027), laryngeal or airway injury (p = 0.016), cough or bucking (p = 0.001), and sore throat (p < 0.001) were significantly lower in the LMA group. There were no statistically significant differences in catheter stability parameters and sinus rhythm maintenance rates between the two groups (p > 0.05). CONCLUSION LMA is feasible, safe, and effective in AF CA as an optimized airway management technique for GA.

Abstract
Negative pressure pulmonary edema (NPPE) is a rare complication that occurs mainly after tracheal extubation. We report a case of postoperative NPPE associated with the use of the i-gel. A 28-year-old woman was scheduled for an emergency right axillary sentinel lymph node excision. During emergence, the patient experienced a sudden onset of airway obstruction, and spontaneous ventilation through the i-gel was impossible. Pink and frothy secretions were noted in the i-gel and the patient's oral cavity. Positive airway pressure with 100% oxygen was applied using a facemask, and the patient was subsequently treated with high-flow oxygen therapy. In this case, laryngospasm or displacement of the i-gel was believed to be the cause of airway obstruction. We recognized that NPPE is likely to occur regardless of the airway device, and the use of the i-gel cannot completely eliminate the possibility of NPPE occurrence.

Indian J Otolaryngol Head Neck Surg 2023; 75:32-38. [PMID: 37007892 PMCID: PMC10050500 DOI: 10.1007/s12070-022-03099-w] [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: 08/28/2020] [Accepted: 11/30/2020] [Indexed: 10/15/2022] Open
Abstract
To investigate the effect of two-step of jaw-thrust technique on the placement of flexible laryngeal mask with both hands. 157 patients scheduled for functional endoscopic sinus surgery were divided into two groups using a random number table method: control group (group C, n = 78) and test group (group T, n = 79). After induction of general anesthesia, the traditional method was applied to insert the flexible laryngeal airway mask in group C, and the two-step of jaw-thrust technique with both hands by the nurse was applied to help place the laryngeal mask in group T. The success rate, alignment status, oropharyngeal leak pressure (OLP) of the laryngeal mask, soft tissue injury of the oropharyngeal cavity and postoperative sore throat, and the incidence of adverse airway event were recorded in both groups. Results: The success rate of the first placement of flexible laryngeal masks in group C and group T were 73.8% and 97.5%, and the final success rates were 97.5% and 98.7%, respectively. Compared with group C, the success rate of first placement in group T was higher, and the difference was statistically significant (P < 0.01). There was no significant difference in the final success rate between the two groups (P = 0.56). The alignment score showed that the placement of group T was better than that of group C, and the difference was statistically significant (P < 0.01). The OLP of group C was 22.1 ± 2.6 cmH2O, and the OLP of group T was 25.4 ± 3.8 cmH2O. The OLP of group T was significantly higher than that of group C (P < 0.01). The incidence of mucosal injury and postoperative sore throat in group T were 2.5% and 5.0%, which were significantly lower than that of 23.0% and 16.7% in group C (both P < 0.01). There was no adverse airway event in each group. Conclusion: The two-step of jaw-thrust technique with both hands can improve the success rate of the first placement of the flexible laryngeal mask and the positioning of the laryngeal mask, increase the sealing pressure of the laryngeal mask, and reduce the incidence of oropharyngeal soft tissue injury and postoperative pharyngeal pain.

Efficacy of laryngeal mask airway against postoperative pharyngolaryngeal complications following thyroid surgery: a systematic review and meta-analysis of randomized controlled studies. Sci Rep 2022; 12:18210. [PMID: 36307459 PMCID: PMC9616911 DOI: 10.1038/s41598-022-21989-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Accepted: 10/07/2022] [Indexed: 12/31/2022] Open
Abstract
This meta-analysis aimed at investigating the effectiveness of laryngeal mask airway (LMA) against postoperative pharyngolaryngeal complications after thyroidectomy. MEDLINE, Cochrane Library, google scholar, and EMBASE databases were searched from inception through February, 2021, for randomized controlled trials (RCTs) comparing the incidence of pharyngolaryngeal complications following the use of LMA or endotracheal tube (ETT). Pooled results from seven RCTs involving 600 patients showed an association of LMA with a reduced risk of postoperative sore throat (POST) at 24 h [risk ratio (RR) 0.75, p = 0.006, four trials], but not at 1 h and 48 h after thyroidectomy. POST severity and hoarseness risk were lower in the LMA group than the ETT group at 1 h, 24 h, and 48 h (all p < 0.05). Nevertheless, hoarseness severity was lower in the LMA group only at postsurgical 48 h [standardized mean difference = - 0.35, p = 0.008, three trials]. Moreover, the risk of emergence cough was lower in patients using LMA than those receiving ETT (RR = 0.14, p = 0.002, two trials). The two groups did not differ in the severity of dysphagia at postoperative 1 h, 24 h, and 48 h. This meta-analysis showed that LMA may be associated with fewer pharyngolaryngeal complications compared to ETT without airway impacts. The limited number of included studies warrants further research to support our findings.

Abstract
Background: The reinforced laryngeal mask airway (RLMA) is difficult to insert due to the flexibility of its inner armored shaft. Many authors agreed that the available techniques have some disadvantages. They use materials that are reusable and require resterilization but may not guarantee infection control particularly during pandemics. The standard method can cause contamination and prone the operator to unanticipated trauma to their finger during placement. So this study aimed to evaluate the usefulness of disposable tongue depressors to aid insertion of the reinforced laryngeal mask airway. Methods: A randomized controlled trial included one hundred ninety-four adult patients of either gender American Society of Anesthesiologists (ASA) I and II attended for elective day case surgery under general anesthesia. Patients were randomly categorized into two groups; each group consisted of ninety-seven. In the first group, insertion of the reinforced laryngeal mask airway was done using the standard technique of digital manipulation whereas the second one is the study group where disposable wooden tongue depressor guided insertion was used. The data were analyzed using SPSS version 23. Data were presented as frequencies or means and standard deviations. Chi-Square, Fisher Exact, and t-test were used. P value < 0.05 was considered significant. Results: No significant difference in basic patients' demographic, anthropometric, and clinical characteristics were noticed between the two groups. The insertion time as well as the total time for RLMA placement, was significantly shorter in the new method group. Trauma was significantly less than 2.1% in the new method group compared to the standard group 10.3%, p=0.003). Conclusion: The disposable wood tongue depressor insertion technique helps facilitate the correct placement of the reinforced laryngeal mask airway.

Abstract
Background Flexible laryngeal mask airways (FLMAs) ventilation have been widely used as airway devices during general anesthesia, especially in otologic surgery. However, the current literature reports that the clinical success and failure rates for FLMA usage are quite different, and there remains a paucity of data regarding factors associated with FLMA failure and complications related to FLMA usage. Purpose To evaluate the success and failure rates of FLMA usage in otologic surgery, the factors associated with FLMA failure and complications related to FLMA usage. Patients and Methods All patients who underwent otologic surgery, including middle ear and mastoid procedures, under general anesthesia at a large tertiary general hospital from 2015 to 2019 were reviewed. The primary outcome was the FLMA failure rate, defined as any airway event requiring device removal and tracheal intubation, including primary and secondary failure. The secondary outcomes were specific clinical factors, including patient sex, age, weight, American Society of Anesthesiologists (ASA) classification, body mass index (BMI) and duration of surgery, which were analyzed as related risk factors. Results Among 5557 patients with planned FLMA use, the final success rate was 98.5%. Sixty-seven percent of the failures occurred during initial introduction of the FLMA, 8% occurred after head and neck rotation, and 25% occurred during the procedures. Two independent clinical factors associated with FLMA failure were male sex and age. Respiratory complications were observed in 0.61% of patients, and the rate of severe nerve and tissue damage associated with FLMA use was 0.05. Conclusion This study demonstrates a high success rate of 98.5% for FLMA use in adults undergoing otologic surgery with rare adverse airway events and injuries complications. Two independent risk factors require attention and thorough and accurate management is necessary for every clinician.

Abstract
BACKGROUND Jcerity Endoscoper Airway is a new back-open endoscopic laryngeal mask airway device with a unique design. Our study sought to compare the implantation, ventilation quality and complications of JEA (Jcerity Endoscoper airway) versus LMA (Laryngeal Mask Airway) Supreme in the procedure of cerebral aneurysm embolization. METHODS In this prospective, randomised clinical trial, 182 adult patients with American Society of Anesthesiologists class Ι-II scheduled for interventional embolization of cerebral aneurysms were randomly allocated into the Jcerity Endoscoper airway group and the LMA Supreme group. We compared success rate of LMA implantation, ventilation quality, airway sealing pressure, peak airway pressure, degree of blood staining, postoperative oral hemorrhage, sore throat and other complications between the groups. RESULTS There were no significant differences between the groups in terms of one-time success rate of LMA implantation, ventilation quality, airway sealing pressure or airway peak pressure. However, LMA Supreme group showed a higher degree of blood staining than the JEA group when the laryngeal mask airway was removed (P = 0.04), and there were also more oral hemorrhages and pharyngeal pain than JEA group (P = 0.03, P = 0.02). No differences were observed between groups in terms of other airway complications related to the LMA. CONCLUSIONS The JEA could not only achieve comparable one-time success rate of implantation and quality of ventilation as the LMA Supreme, but also have lower blood staining degree of mask and less sore throat in patients undergoing perioperative anticoagulation for cerebral aneurysm interventional embolization.

Abstract
OBJECTIVE A prospective, randomized, and controlled study was conducted to investigate the effect of two-step jaw-thrust technique on the placement of flexible laryngeal mask (FLMA) with both hands. METHODS Between November 2019 and January 2020, 160 patients scheduled for functional endoscopic sinus surgery with general anesthesia were enrolled in this study and were divided into two groups (n=80 each) using a random number table method: control group (group C) and test group (group T). After the induction of general anesthesia, the traditional method was applied to insert the flexible laryngeal airway mask in patients of group C, and the two-step jaw-thrust technique with both hands by the nurse was applied to help place the laryngeal mask in patients of group T. The success rate, alignment status by fibroscope (FOB) score, oropharyngeal leak pressure (OLP) of the laryngeal mask, oropharyngeal cavity soft tissue injury and postoperative sore throat, and the incidence of adverse airway event were compared between the two groups. (The registry of clinical trial: Chinese Clinical Trial Register, ChiCTR2100053017, https://www.chictr.org.cn). RESULTS 78 patients in group C and 79 patients in group T were in includedfinal analysis. The success rates of the first placement of flexible laryngeal masks in patients of group C and group T were 73.81% and 97.52%, respectively. The final success rates were 97.52% and 98.81%, respectively. The success rate of first placement in group T was significantly higher than that of group C. There was no significant difference in the final success rate between the two groups (P=0.561). The alignment score showed that the placement of group T was significantly better than that of group C. The OLP of group T (25.43±3.82 cm) was significantly higher than that of group C (22.13±2.62 cm). The incidences of mucosal injury and postoperative sore throat in group T were 2.52% and 5.01%, which were significantly lower than those of 23.02% and 16.72% in group C. There was no adverse airway event in each group. CONCLUSION The two-step jaw-thrust technique with both hands can improve the success rate of the first placement of the flexible laryngeal mask and the positioning of the laryngeal mask, increase the sealing pressure of the laryngeal mask, and reduce the incidence of oropharyngeal soft tissue injury and postoperative pharyngeal pain.

Abstract
BACKGROUND Autoimmune pulmonary alveolar proteinosis is an ultra-rare pulmonary disease. Whole lung lavage (WLL) is considered the gold standard therapy. We report a protocol for a new modified lavage technique (nMLT) in which controlled repetitive manual hyperinflation (MH) and intermittent chest percussion are used to enhance WLL efficacy. METHODS We included all subjects with autoimmune pulmonary alveolar proteinosis treated with nMLT between 2013 and 2018. nMLT consisted of repetitive MH with intermittent chest percussion every third wash. We reported: instilled volume, protein concentration, and optical density using spectrophotometry. Pulmonary function (FVC %predicted and DLCO %predicted) at start of nMLT was recorded. Data are displayed as mean (±SD), median [interquartile range], or number (%). Comparisons within individuals were made using Students t test. RESULTS We included 11 subjects (64% male) in whom a total of 67 nMLTs were performed. One nMLT consisted of 15 [12-18] washes. Protein removal was 9.80 [7.52-12.66] g per nMLT. After the first, second, and third cycle of 3 washes, 56% [49% to 61%], 81% [77% to 84%], and 91% [88% to 94%] of the final protein yield was removed, respectively. Optical density was measured 116 times and increased from 1.13 (±0.52) to 1.31 (±0.52) after MH (P<0.001). CONCLUSION Efficacy of WLL seems to be enhanced by applying MH every 3 washes. Our technique of WLL with nMLT could be used to increase the amount of protein recruited while instilling the lung with the smallest volume of fluid as possible.

Abstract
BACKGROUND upper airway complications are common sequelae of endotracheal tube (ETT) intubation, and systemic corticosteroids are considered a mainstay treatment for this problem. Drug-eluting ETT may present an attractive option for topical steroid delivery while avoiding systemic side effects and improving the therapeutic outcome. The objective of the present study is to evaluate the reduction of tube-related tracheal morbidity via a self-designed steroid-eluting ETT with controlled sustained release properties in an animal model. METHODS steroid-eluting ETTs were coated by poly(lactic-co-glycolic acid) -electrospun nanofibers loaded with mometasone furoate (MF) as a model drug. Animals were randomly assigned into three equal groups: non-intubated, blank-ETT, and loaded-ETT. The intubation interval was 1 week. Specimens were analyzed by histology, specific fibrosis staining, and scanning electron microscopy (SEM). RESULTS the blank-ETT group exhibited a significant increase in tracheal mucosal thickness compared to the loaded-ETT and control groups. Average tracheal mucosal thickness was 112 ± 34, 242 ± 49, and 113 ± 43 μm in the control, blank-ETT, and loaded-ETT groups, respectively. The blank-ETT group exhibited a significant increase in tracheal fibrosis compared to the loaded-ETT and control groups. Relative fibrosis values were 0.07 ± 0.05, 0.154 ± 0.1, and 0.0984 ± 0.084% for the control, blank-ETT, and loaded-ETT groups, respectively. While SEM imaging showed normal surface structures in the control group, intubated blank-ETT rats showed severe surface structural damage, whereas only mild damage was observed in the loaded-ETT group. CONCLUSIONS local sustained release of MF via a self-designed drug-eluting ETT is a potential therapeutic approach which may significantly reduce tube-related upper airway morbidity.

Abstract
OBJECTIVES Although the flexible laryngeal mask airway (FLMA) provides considerable advantages in head and neck procedures, little is known about its safety and efficacy in functional endoscopic sinus surgery (FESS). We conducted a retrospective study to evaluate the success rate of FLMA and relevant airway complications in FESS under general anaesthesia. METHODS A retrospective review of consecutive patients who underwent FESS for chronic rhinosinusitis was performed from 2015 to 2019. All patients scheduled for FLMA ventilation were identified. Patient characteristics, length of the surgery, FLMA size, failed FLMA cases requiring endotracheal intubation, immediate adverse airway events and delayed airway injuries were recorded. The primary outcomes included the FLMA success rate, which was defined as primary success after induction and final success after the whole surgical procedure. The secondary outcomes were specific clinical factors associated with FLMA failure and airway complications related to FLMA usage. RESULTS Of the 6661 patients included in our study, primary success was achieved in 6572 (98.7%), and final success was achieved in 6512 (97.8%). Failure occurred in 89 patients (1.3%) during induction, in 14 (0.2%) during surgical preparation and in 46 (0.7%) during the intraoperative procedure. All patients with failed FLMA ventilation were successfully switched to endotracheal intubation. Male sex, advanced age, higher American Society of Anesthesiologists grade (ASA) and higher body mass index (BMI) were independent risk factors associated with failed FLMA. Immediate adverse respiratory events were observed in 0.85% of the patients, and delayed airway injuries associated with use of FLMA were observed in 0.07%. CONCLUSION This retrospective study demonstrates a high success rate for FLMA (97.8% in 6661 patients undergoing FESS). Adverse airway events and injuries associated with FLMA are rare, but clinicians should remain vigilant so that early diagnosis and prompt treatment can be provided.

Abstract
Background The flexibility of the long flexometallic tube makes insertion of the flexible reinforced laryngeal mask airway (f-LMA) difficult. We compared the usefulness of rigid lightwand-guided f-LMA insertion with standard digital manipulation. Material/Methods Fifty-four patients (aged 19–70 years) were randomly divided into a control group (digital manipulation technique) or the lightwand group (lightwand-guided insertion technique). The insertion profiles, oropharyngeal leak pressure (OLP), peak inspiratory pressure (PIP), expiratory tidal volume, and ventilatory score were measured in patients with neutral, extension, rotation, flexion, and re-neutral head-neck positions in turn. Results The success rate and ease of insertion did not differ between groups, but the insertion time was longer in the lightwand group. The fiberoptic laryngeal view was significantly better in the lightwand group than in the control group. However, the OLP, PIP, expiratory tidal volume, and ventilatory scores were not significantly different between groups according to head-neck positions. The extension posture was associated with a significant negative effect on ventilation, but ventilation returned to initial levels with the other postures. Conclusions Lightwand-guided f-LMA insertion showed a better fiberoptic laryngeal view than standard digital manipulation, but no improvement in the ventilatory state was observed due to position. Therefore, lightwand-guided insertion could facilitate correct placement of the f-LMA, but it has limited clinical usefulness.

Supraglottic airway device versus tracheal intubation and the risk of emergent postoperative intubation after general anaesthesia in adults: a retrospective cohort study. Br J Anaesth 2020; 126:738-745. [PMID: 33341223 DOI: 10.1016/j.bja.2020.10.040] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 10/20/2020] [Accepted: 10/31/2020] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND We examined the association between emergent postoperative tracheal intubation and the use of supraglottic airway devices (SGAs) vs tracheal tubes. METHODS We included data from adult noncardiac surgical cases under general anaesthesia between 2008 and 2018. We only included cases (n=59 991) in which both airways were deemed to be feasible options. Multivariable logistic regression, instrumental variable analysis, propensity matching, and mediation analysis were used. RESULTS Use of a tracheal tube was associated with a higher risk of emergent postoperative intubation (adjusted absolute risk difference [ARD]=0.80%; 95% confidence interval (CI), 0.64-0.97; P<0.001), and a higher risk of post-extubation hypoxaemia (ARD=3.9%; 95% CI, 3.4-4.4; P<0.001). The effect was modified by the use of non-depolarising neuromuscular blocking agents (NMBAs); mediation analyses revealed that 28.9% (95% CI, 14.4-43.4%; P<0.001) of the main effect was attributable to NMBA. Airway management modified the association of NMBA and risk of emergent postoperative intubation (Pinteraction=0.02). Patients managed with an SGA had higher odds of NMBA-associated reintubation compared to patients managed with a tracheal tube (adjusted odds ratio [aOR]=3.65, 95% CI, 1.99-6.67 vs aOR=1.68, 95% CI, 1.29-2.18 [P<0.001], respectively). CONCLUSIONS In patients undergoing procedures under general anaesthesia that could be managed with either SGA or tracheal tube, use of an SGA was associated with lower risk of emergent postoperative intubation. The effect can partly be explained by use of NMBAs. Use of NMBAs in patients with an SGA appears to increase the risk of emergent postoperative intubation.

Abstract
Background The prevalence of potential risk factors for postoperative cough after thyroidectomy remain unknown. The current study aimed to research postoperative cough in patients undergoing thyroid surgery prospectively. Methods Adult patients who underwent primary thyroid surgery were selected prospectively. Data regarding age, sex, BMI, pathology and surgical procedure were collected and analyzed. The Leicester Cugh Questionnaire (LCQ) was required to be completed by all patients before operation, 2 weeks and 4 weeks after operation. Results There were 1264 patients enrolled in total. Eleven patients with vocal cord paralysis were excluded. In patients with benign disease, postoperative cough occurred in 61 patients, with an prevalence rate of 17. 0% compared to an prevalence rate of 33.1% in patients with malignant disease; the difference was significant. For benign patients, the factors of smoking and operation time were independently related to the occurrence of postoperative cough. For malignant patients, the factors of smoking, operation time, operation extent, and the number of positive nodes at level 6 were independently related to the occurrence of postoperative cough. There was no significant difference regarding the LCQ score in patients with benign or malignant disease at the preoperative and the postoperative 4-week time periods. Patients with malignant disease had a significantly lower LCQ score than patients with benign disease at the postoperative 2-week time point (p = 0.004). Conclusions Patients undergoing thyroid cancer surgery had a higher incidence of postoperative cough and were also associated with a decreased cough-related quality of life. The factors of smoking and operation time were the most important predictors for postoperative cough after thyroidectomy.

Abstract
Supplemental Digital Content is available in the text Background Intravertebral and general anesthesia (GA) are two main anesthesia approaches but both have defects. This study was aimed to evaluate the effect of subarachnoid anesthesia combined with propofol target-controlled infusion (TCI) on blood loss and transfusion for total hip arthroplasty (THA) in elderly patients in comparison with combined spinal-epidural anesthesia (CSEA) or GA. Methods Totally, 240 patients (aged ≥65 years, American Society of Anesthesiologists [ASA] I–III) scheduled for posterior THA were enrolled from September 1st, 2017 to March 1st, 2018. All cases were randomly divided into three groups to receive CSEA (group C, n = 80), GA (group G, n = 80), or subarachnoid anesthesia and propofol TCI (group T, n = 80), respectively. Primary outcomes measured were intra-operative blood loss, autologous and allogeneic blood transfusion, mean arterial pressure at different time points, length of stay in post-anesthesia care unit (PACU), length of hospital stay, and patient satisfaction degree. Furthermore, post-operative pain scores and complications were also observed. The difference of quantitative index between groups were analyzed by one-way analysis of variance, repeated measurement generalized linear model, Student-Newman-Keuls test or rank-sum test, while ratio index was analyzed by Chi-square test or Fisher exact test. Results Basic characteristics were comparable among the three groups. Intra-operative blood loss in group T (331.53 ± 64.33 mL) and group G (308.03 ± 64.90 mL) were significantly less than group C (455.40 ± 120.48 mL, F = 65.80, P < 0.001). Similarly, the autologous transfusion of group T (130.99 ± 30.36 mL) and group G (124.09 ± 24.34 mL) were also markedly less than group C (178.31 ± 48.68 mL, F = 52.99, P < 0.001). The allogenetic blood transfusion of group C (0 [0, 100.00]) was also significantly larger than group T (0) and group G (0) (Z = 2.47, P = 0.047). Except for the baseline, there were significant differences in mean arterial blood pressures before operation (F = 496.84, P < 0.001), 10-min after the beginning of operation (F = 351.43, P < 0.001), 30-min after the beginning of operation (F = 559.89, P < 0.001), 50-min after the beginning of operation (F = 374.74, P < 0.001), and at the end of operation (F = 26.14, P < 0.001) among the three groups. Length of stay in PACU of group T (9.41 ± 1.19 min) was comparable with group C (8.83 ± 1.26 min), and both were significantly shorter than group G (16.55 ± 3.10 min, F = 352.50, P < 0.001). There were no significant differences among the three groups in terms of length of hospitalization and post-operative visual analog scale scores. Patient satisfaction degree of group T (77/80) was significantly higher than group C (66/80, χ2 = 7.96, P = 0.004) and G (69/80, χ2 = 5.01, P = 0.025). One patient complained of post-dural puncture headache and two complained of low back pain in group C, while none in group T. Incidence of post-operative nausea and vomiting in group G (10/80) was significantly higher than group T (3/80, χ2 = 4.10, P = 0.043) and group C (2/80, χ2 = 5.76, P = 0.016). No deep vein thrombosis or delayed post-operative functional exercise was detected. Conclusions Single subarachnoid anesthesia combined with propofol TCI seems to perform better than CSEA and GA for posterior THA in elderly patients, with less blood loss and peri-operative transfusion, higher patient satisfaction degree and fewer complications.

Abstract
BACKGROUND The innervation of the shoulder-upper-extremity area is complicated and unclear. Regional anesthesia with a brachial plexus and cervical plexus block is probably inadequate for the proximal humeral surgery. Missing blockade of the T1-T2 nerves may be the reason. We conduct this prospective randomized controlled trial (RCT) to explore whether an additional T2 thoracic paravertebral block (TPVB) can improve the success rate of regional anesthesia for elderly patients in proximal humeral fracture surgery. METHODS/DESIGN The patients aged 65 years or older, referred for anterior-approach proximal humeral fracture surgery, will be enrolled. Each patient will be randomly assigned 1:1 to receive a combined interscalene brachial plexus with superficial cervical plexus block (IC) (combined interscalene brachial plexus with superficial cervical plexus block) or an IC block combined with thoracic paravertebral block (ICTP) block (combined thoracic paravertebral block with brachial plexus and superficial cervical plexus block). The primary outcome is the success rate of regional anesthesia without rescue analgesic methods. The secondary outcomes are as follows: sensory block at the surgical area, proportion of patients who need rescue anesthesia (intravenously administered remifentanil or conversion to general anesthesia), cumulative doses of intraoperative vasoactive medications and adverse events. The total sample size is estimated to be 80 patients. DISCUSSION This RCT aims to confirm whether an additional T2 TPVB can provide better anesthetic effects of regional anesthesia with brachial and cervical plexus block in elderly patients undergoing proximal humeral surgery.

Abstract
OBJECTIVES The forced oscillation technique (FOT) is the method of choice for assessment of respiratory tissue mechanics. A laryngeal mask airway (LMA) is increasingly used to secure the airways in subjects under sedation or general anesthesia. While FOT is routinely performed using an endotracheal tube (ETT), the accuracy of information about airway and tissue mechanics obtained with FOT using a LMA has not been characterized. Therefore, we compared the mechanical parameters obtained with FOT using LMA and ETT in rabbits. APPROACH FOT was performed through a LMA at normal and reduced oscillatory amplitudes in anesthetized and mechanically ventilated rabbits (n = 9) at positive end-expiratory pressures (PEEP) of 3 and 6 cmH2O. These measurements were repeated at normal amplitude for the same animal using an ETT. Airway resistance, inertance, respiratory tissue damping (G) and elastance (H) were measured under each condition by FOT. The potential bias of the distensible upper airways when FOT was applied using LMA was assessed with a simulation study. MAIN RESULTS Values of parameters reflecting airway mechanics were significantly higher when measured using LMA at both PEEPs and oscillatory amplitudes than with ETT. Conversely, regardless of the condition, there was a correlation (r = 0.89 both at normal and reduced amplitudes; p < 0.0001) with good agreement (mean bias of 8.8 cmH2O/l and 11.3 cmH2O/l) in H, whereas G was systematically lower when obtained with LMA than with ETT at PEEP 3 (21.1% ± 7.2% and 9.6% ± 6.9% at normal and reduced oscillatory amplitudes, respectively) and 6 cmH2O (15.1% ± 8.2%, 1.6% ± 9.4%, p < 0.05 for all). SIGNIFICANCE Mechanical properties of the airways and the respiratory tissues, particularly for respiratory tissue stiffness, can be reliably assessed using LMA. However, the involvement of a longer laryngo-tracheo-bronchial pathway when using LMA should be considered for airway resistance and inertance, whereas upper airway shunting may affect the assessment of respiratory tissue damping.

Abstract
Endotracheal intubation (ETI) and laryngeal mask airway (LMA) in terms of hemodynamics and reaction were compared. A total of 54 general anesthesia patients were randomized into two groups with 27 cases in each group. Acceleration index (ACI), cardiac index (CI), cardiac output (CO), left cardiac work (LCW), systemic circulation resistance (SVR), mean arterial pressure (MAP), heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded at 12 time-points: before surgery (T0), start effect (T1), lost consciousness (T2), before ETI or LMA (T3), 1 min (T4), 3 min (T5), 5 min (T6) after ETI or LMA, the beginning of surgery (T7), 30 min (T8), 1 hour (T9) after surgery, the end of surgery (T10) and extubation (T11). In each group these indexes went down and rose up gently during surgery except for T4 (intubation) and T11 (extubation) in ETI. These indexes reached the highest at T11 (extubation). This is due to the stimulus on mucosa and muscle of root of tongue, throat and epiglottis from the windpipe. The stimulus excites sympathetic nerve and increases the release of catecholamine. As a result, the heart beats faster and blood pressure rises. However, the range in the LMA group is smaller especially at T4 and T11. This is most likely due to LMA not stimulating the trachea. SVR, MAP, HR, SBP and DBP were lower in LMA with statistical significance in some time-points. The other indexes such as ACI, CI, CO and LCW were significantly higher in LMA (P<0.05). These results indicated that LMA can be suitable for use in general anesthesia for less stimulation. The airway with LMA in patients undergoing gynecological cancer operation is better than ETI in keeping stable hemodynamics and producing less anesthetic complications with smooth recovery from general anesthesia.

ACTA ACUST UNITED AC 2018; 65:434-440. [PMID: 29970248 DOI: 10.1016/j.redar.2018.05.004] [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: 02/28/2018] [Revised: 05/05/2018] [Accepted: 05/11/2018] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To evaluate clinical usefulness of ultrasound images of the upper airway in order to check correct laryngeal mask placement. MATERIAL AND METHODS A prospective observational study was conducted on patients scheduled for abdominal surgery under general anaesthesia, in whom the patency of the upper airway was ensured using an Ambu®AuraGainTM laryngeal mask. An ultrasound scan was performed of the upper-airway in the cranio-caudal direction and with longitudinal scans in the anterior midline and parasagittal axis, in three moments: before, after inserting and after removing the mask. All recorded images were evaluated in a second time by a radiologist-expert in upper airway ultrasound. Subsequently, the ultrasound data were related to the clinical difficulty of the insertion and presence of air leaks. RESULTS Data was collected from 30 patients (20 females and 10 males) being operated on for abdominal hysterectomy (15), eventroplasty (6), uterine myomectomy (3), and umbilical (4) and inguinal herniorrhaphy (2). The blind insertion of the masks did not present difficulties in 24 (80%) patients. Air leakage was detected in 8 (26.7%) patients, which was moderate in 7 cases and severe in one of them. The ultrasound findings confirmed good mask placement in 22 (73.3%) patients. Anatomical airway changes after laryngeal mask extraction were only observed in 3 (12%) patients, all of them minor. There was a statistically significant association (P<.05) between difficulty in inserting the device and the level of air leakage. CONCLUSIONS Upper airway ultrasound is a useful diagnostic method to evaluate laryngeal mask placement. Laryngeal oedema was not observed after removal of the device.

Abstract
Congenital fibre type disproportion (CFTD) is a rare type of myopathy that is characterised by muscle weakness and hypotonia during childhood. Clinical features include motor delay, feeding difficulties, limb weakness, joint contractures, and scoliosis. A report is presented of the anaesthetic management of a 3-year-old girl with CFTD myopathy associated with a mutation of the TPM3 gene, scheduled for adenotonsillectomy because of obstructive sleep apnoea hypopnoea syndrome (OSAHS). The main concerns were the possible susceptibility to malignant hyperthermia, the risk of anaesthesia-induced rhabdomyolysis, a greater sensitivity to non-depolarising muscle relaxants, and the presence of OSAHS. Total intravenous anaesthesia with propofol and the use of rocuronium/sugammadex appear to be safe options. Given the high risk of respiratory compromise and other complications, patients should be closely monitored in the post-operative period.

Abstract
OBJECTIVE To compare the safety of sevoflurane anesthesia with laryngeal mask and tracheal intubation in cesarean section in women with heart disease. METHODS Fifty-two pregnant women with heart diseases undergoing cesarean section were randomized into laryngeal mask (LAM) group and tracheal intubation group. In LAM group, 6% sevoflurane was given at the rate of 6 L/min for induction with a maintenance sevoflurane concentration of 3%. In the intubation group, 1.5 mg/kg propofol and 1 µg/kg remifentanil were injected intravenously, and after achieving D0 with Narcotrend monitoring, 0.9 mg/kg rocuronium was injected and intubation was performed 1 min later. The systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and heart rate (HR) were recorded in the two groups before anesthesia induction (T0), at intubation or laryngeal mask placement (T1), skin incision (T2), and extubation or laryngeal mask removal (T3). The surgery to fetal birth time, uterine incision to fetal childbirth time, drug discontinuation to awake time, and newborn Apgar scores were also recorded. Sevoflurane consumption and maternal comfort during hospitalization were compared between the two groups. RESULTS In LAM group, HR and MBP at T1 and T3 were significantly lower than those in the intubation group (P<0.05). The drug discontinuation to extubation time and to awaken time were significantly shorter in LAM group than in the intubation group (P<0.05), but the operation time and fetal child birth time were comparable between the two groups (P>0.05). The women in LAM group reported better physical and psychological comforts than those in the intubation group (P<0.05). The neonatal Apgar scores and the scores of health education, satisfaction with hospital environment and service were all similar between the two groups (P>0.05). CONCLUSION Sevoflurane anesthesia with laryngeal mask can achieve satisfactory anesthetic effects in cesarean section in women with heart disease.

Inhalation of volatile anesthetics via a laryngeal mask is associated with lower incidence of intraoperative awareness in non-critically ill patients. PLoS One 2017; 12:e0186337. [PMID: 29073151 PMCID: PMC5658000 DOI: 10.1371/journal.pone.0186337] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2017] [Accepted: 10/01/2017] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Increased incidence of intraoperative awareness was reported in critically ill patients during major operations, particularly under total intravenous (TIVA) or endotracheal general anesthesia (ETGA). However, the incidence and effect of anesthesia techniques on awareness in generally healthy, non-critically ill patients during operations have yet to receive significant attention. METHODS AND RESULTS This retrospective matched case-control study was conducted between January 2009 to December 2014. Surgical patients (ASA physical status I-III) whom reported intraoperative awareness during this study period were interviewed and their medical records were reviewed. The potential risk factors for awareness were compared with the non-case matched controls, who were randomly selected from the database. A total of 61436 patients were included and 16 definite cases of intraoperative awareness were identified. Patients who received ETGA and TIVA had significantly higher incidence of developing awareness compared to those who were anesthetized using laryngeal masks (LMA) (P = 0.03). Compared with the matched controls (n = 80), longer anesthesia time was associated with increased incidence of awareness (odds ratio 2.04; 95% CI 1.30-3.20, per hour increase). Perioperative use of muscle relaxant was also associated with increased incidence of awareness, while significantly lower incidence of awareness was found in patients who were anesthetized with volatile anesthetics. CONCLUSIONS The overall incidence of awareness was 0.023% in the ASA≤ III surgical patients who received general anesthesia. Anesthesia with a laryngeal mask under spontaneous ventilation and supplemented with volatile anesthetics may be the preferred anesthesia technique in generally healthy patients in order to provide a lower risk of intraoperative awareness.

Acta Anaesthesiol Scand 2017; 61:781-789. [PMID: 28556897 DOI: 10.1111/aas.12914] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2017] [Revised: 04/25/2017] [Accepted: 05/08/2017] [Indexed: 01/01/2023]
Abstract
BACKGROUND Securing the airway is one of the most important responsibilities in anaesthesia. Injuries related to airway management can occur. Analysis from closed claims can help to identify patterns of injury, risk factors and areas for improvement. METHODS All claims to The Norwegian System of Compensation to Patients from 1 January 2001 to 31 December 2015 within the medical specialty of anaesthesiology were studied. Data were extracted from this database for patients and coded by airway management procedures. RESULTS Of 400 claims for injuries related to airway management, 359 were classified as 'non-severe' and 41 as 'severe'. Of the severe cases, 37% of injuries occurred during emergency procedures. Eighty-one claims resulted in compensation, and 319 were rejected. A total of €1,505,344 was paid to the claimants during the period. Claims of dental damage contributed to a numerically important, but financially modest, proportion of claims. More than half of the severe cases were caused by failed intubation or a misplaced endotracheal tube. CONCLUSION Anaesthesia procedures are not without risk, and injuries can occur when securing the airway. The most common injury was dental trauma. Clear patterns of airway management that resulted in injuries are not apparent from our data, but 37% of severe cases were related to emergency procedures which suggest the need for additional vigilance. Guidelines for difficult intubation situations are well established, but adherence to such guidelines varies. Good planning of every general anaesthesia should involve consideration of possible airway problems and assessment of pre-existing poor dentition.
