Abstract
Background Ventilator-Associated Pneumonia (VAP) severely impacts stroke patients' prognosis after endovascular treatment. Hence, this study created a nomogram to predict the occurrence of VAP after endovascular treatment. Methods The individuals with acute ischemic stroke and large vessel occlusion (AIS-LVO) who received mechanical ventilation and endovascular therapy between July 2020 and August 2023 were included in this retrospective study. The predictive model and nomogram were generated by performing feature selection optimization using the LASSO regression model and multifactor logistic regression analysis and assessed the evaluation, verification and clinical application. Results A total of 184 individuals (average age 61.85 ± 13.25 years, 73.37% male) were enrolled, and the rate of VAP occurrence was found to be 57.07%. Factors such as the Glasgow Coma Scale (GCS) score, duration of stay in the Intensive Care Unit (ICU), dysphagia, Fazekas scale 2 and admission diastolic blood pressure were found to be associated with the occurrence of VAP in the nomogram that demonstrating a strong discriminatory power with AUC of 0.862 (95% CI, 0.810-0.914), and a favorable clinical net benefit. Conclusion This nomogram, comprising GCS score, ICU duration, dysphagia, Fazekas scale 2 and admission diastolic blood pressure, can aid clinicians in predicting the identification of high-risk patients for VAP following endovascular treatment in large vessel occlusion stroke.

Kuo CW, Allen CT, Huang CC, Lee CJ. Murray secretion scale and fiberoptic endoscopic evaluation of swallowing in predicting aspiration in dysphagic patients. Eur Arch Otorhinolaryngol 2017; 274:2513-2519.

Abstract
The objective of this retrospective review is to evaluate the ability of the Murray secretion scale to predict aspiration as determined by fiberoptic endoscopic evaluation of swallowing. Patients with dysphagia undergoing a fiberoptic endoscopic evaluation of swallowing study between January 2013 and November 2015 from a single, tertiary care institution were retrospectively reviewed. The Murray secretion scale and penetration aspiration scale on fiberoptic endoscopic evaluation of swallowing examination were determined. Spearman's correlation analysis, sensitivity, specificity, predictive values, and relative risk evaluating the relationship between the Murray secretion scale and aspiration on fiberoptic endoscopic evaluation of swallowing were calculated. Subgroups of head and neck cancer patients, penetration group, and aspiration group were also analyzed. The mean age of the cases (N = 212) was 62.4 years. Eighty percent were male. There was a strong correlation between Murray secretion scale grade and penetration aspiration scale score (r = 0.785, p < 0.001). The sensitivity and specificity of a Murray secretion scale grade 2 or higher in predicting aspiration were 74 and 90%, respectively. Individuals with a Murray secretion scale grade of 2 or higher were 13.6 times more likely to aspirate than patients with a lower Murray secretion scale grade. All subgroups showed similar trend. Determination of a Murray secretion scale grade, determined by flexible nasopharyngoscopy, may predict patients at high risk for aspiration. In clinical scenarios where more complete assessments of aspiration risk are immediately impossible or impractical, the Murray secretion scale grade may add valuable information to assist in clinical decision-making in patients with dysphagia.

Abstract
The placement of a tracheostomy has become a routine procedure for intensive care unit patients who are mechanical ventilator dependent for a period of time, usually exceeding 1 or 2 weeks. It is vital for the intensivist to be familiar with all aspects of tracheostomies care including the timing of converting a patient to a tracheostomy, types of procedure, risks and benefits, and issues of daily care including oral feedings, speech, and decannulation. In this article we provide a comprehensive review for the intensivist regarding tracheostomies in the intensive care setting. We specifically review indications, timing, surgical options including percutaneous dilation tracheostomy, complications, decannulation, oral feeding, speaking devises, stomal stents, and routine tracheostomy care.

Abstract
An endotracheal tube placed in the larynx, even for a short time, causes at least superficial mucosal damage, an injury that normally heals readily. Long-term intubation, on the other hand, may cause pressure necrosis that can extend into submucosa, perichondrium, and eventually cartilage. The sites of involvement include the medial surface of the arytenoid cartilages, vocal processes, cricoarytenoid joints, posterior glottis, and subglottis. We review the pathogenesis, endoscopic recognition, classification, and progression of intubation injuries and examine the many variables that influence them. Diagrammatic flow charts trace the acute injuries through to their chronic sequelae, including subglottic stenosis, which is commoner in infants and children, and posterior glottic stenosis, which is commoner in adults. Systematic endoscopic assessment, under general anesthesia, using rigid telescopes to evaluate laryngeal damage during intubation is recommended and critically discussed. Endoscopy permits an informed judgment with regard to continuation of intubation. Depending on the severity and depth of ulceration, intubation can be continued (sometimes with a tube of smaller diameter) or tracheotomy performed, with an awareness of the attendant risks and benefits. Unnecessary tracheotomies may be avoided. Further, it may be possible to minimize untoward outcomes of prolonged intubation by using management techniques directed at known risk factors.

Abstract
The objective of this study was to examine the vocal symptoms and acoustic changes perceived in the short period after endotracheal intubation, and to find the association between these changes and the endotracheal tube parameters. A total of 35 subjects were included. They were examined preoperatively, and 2 and 24 hours postoperatively. The vocal symptoms of hoarseness, vocal fatigue, loss of voice, throat clearing, globus pharyngeus, throat pain, and the acoustic variables mainly average fundamental frequency, relative average perturbation, shimmer, noise to harmony ratio, voice turbulence index, habitual pitch, and maximum phonation time (MPT) were assessed as such and in relation to the following endotracheal tube parameters: duration of anesthesia, number of intubation attempts, size of the tube, cuff volume, cuff mean pressure, and the emergence. The association between anesthesia parameters with incidence of vocal complaints and changes in acoustic parameters were examined using logistic and linear regression. Vocal fatigue was associated significantly with the increase in cuff volume and the number of intubation attempts. Throat clearing was associated significantly with the increase in cuff mean pressure. Only the increase in habitual pitch was associated significantly with the increase in cuff volume. The acute short-term effect of endotracheal intubation on voice is significant. The most important endotracheal tube parameters that affect the vocal changes are the cuff mean pressure and volume. The laryngeal contribution to these vocal changes seems to be minimal. All vocal symptoms increased significantly except for globus pharyngeus at 2 hours postoperatively. The acoustic parameters did not change significantly except for a decrease in MPT. At 24 hours postoperatively, all vocal symptoms subsided with no significant difference to baseline value. The habitual pitch increased significantly, and the rest of the parameters remained comparable to baseline value.

Abstract
Although clinically evident aspiration is common in subjects with dysphagia, a significant proportion may aspirate silently, i.e., without any outward signs of swallowing difficulty. This article reviews the literature on the prevalence, etiology, and prognostic significance of silent aspiration. An electronic database search was performed using silent aspiration, aspiration, dysphagia, and stroke as search terms, together with hand-searching of articles. Silent aspiration has been described in many conditions and subgroups of patients (including normal individuals), using a number of detection methods, making comparisons a challenge. The best data are for acute stroke, in which 2%-25% of patients may aspirate silently. Mechanisms associated with silent aspiration may include central or local weakness/incoordination of the pharyngeal musculature, reduced laryngopharyngeal sensation, impaired ability to produce a reflexive cough, and low substance P or dopamine levels. In terms of prognosis, silent aspiration has been associated with increased morbidity and mortality in many but not all studies. However, some degree of silent aspiration at night may be normal in healthy individuals. The phenomenon of silent aspiration is poorly understood and further research is needed to improve methods of detection and thereby better define its prevalence and prognostic significance.

Abstract
The traumatic effects of tracheal intubation are well recognized. Whilst these usually follow prolonged intubation, acute lesions have been described, usually following a traumatic intubation technique. We present a case of acute, localized swelling of the right laryngeal ventricle which followed an entirely atraumatic intubation by an experienced paediatric anaesthetist. The lesion was not present at the time of intubation, but developed subsequently during the surgical procedure. Although previously observed at our institution, such lesions have not been described in the literature. The potential for a diagnostic pitfall, by mistaking the lesion for a laryngeal cyst or nodule, is discussed.

Abstract
Prolonged endotracheal intubation can cause injuries to 1 or more regions of the larynx, making safe extubation impossible and leading to tracheostomy in many patients. Unfortunately, a considerable number of these patients do not benefit from early laryngeal evaluation, which may reveal potentially treatable soft, obstructive tissue before it undergoes irreversible fibrosis. Between July 1992 and December 1995, we performed immediate direct telelaryngoscopy on 142 adults who required tracheostomy because of failed extubation. When present, obstructive tissue was removed with microsurgical techniques. One hundred twenty-nine (90%) patients were decannulated within 3 weeks. The 2 main reasons for failure of early decannulation were intractable granulation (in patients with insulin-dependent diabetes) and coexisting tracheal stenosis. Immediate telelaryngoscopy is recommended in all patients who require tracheostomy because of failed extubation. Flexible laryngoscopy is not adequate for thorough assessment of laryngeal damage from prolonged intubation.

Abstract
Endotracheal intubation is associated with significant laryngeal sequelae that range in severity from mild hoarseness to life-threatening tracheal stenosis. Although the most severe trauma appears to be related to prolonged intubation, even short-term intubation (< 1 day) can adversely affect laryngeal and vocal function. Concern is warranted for all intubated patients, but particularly for the vocal athlete whose livelihood and identity depend on optimal vocal function. It is proposed that the vocal athlete faced with endotracheal intubation risk warrants careful multidisciplinary management. A number of intubation risk factors have been identified in the literature; however, clinical management of vocal athletes who undergo intubation has not been addressed. In medical settings where adverse intubation outcomes can lead to litigation, this clinical management protocol is expected to improve the probability of favorable voice outcome following endotracheal intubation.

Abstract
Respiratory complications occurring in the immediate postoperative period are well known to the seasoned postanesthesia care unit nurse. The most common adverse respiratory events originating in this setting are airway obstruction, hypoventilation, hypoxemia, and pulmonary aspiration of gastric contents. The focus of this article details airway compromise secondary to edema of the larynx and adjacent structures as a consequence of translaryngeal intubation. Postextubation laryngeal edema is a relatively rare problem; however, severe episodes may have life-threatening ramifications. A review of pertinent airway anatomy and airflow dynamics as they relate to this compromised airway condition is presented. Risk factors for the development of postextubation laryngeal edema plus contemporary patient treatment strategies will be reinforced. Patient management issues are addressed, with emphasis placed on the ambulatory patient in which discharge to a remote location is anticipated.

Abstract
Bedside videolaryngoscopy of 73 cardiovascular surgical patients was performed before and after intubation to identify risk factors, incidence, and site of injury to the larynx. Nineteen of 44 patients with abnormal preintubation examination findings had granulation tissue present on a vocal process, compared with 3 of 20 patients who had normal findings on preintubation examination ( p < 0.05). Recent smoking history was elicited from 2 of 20 patients who had normal findings on preintubation examination and from 20 of the 44 patients who had abnormal findings on preintubation examination ( p < 0.01). Laryngeal nerve paresis was identified in 21 of 64 patients after extubation and was present in 7 patients before intubation. Videolaryngoscopy provides a high-quality permanent record of the laryngeal examination and is easily obtained in the critical care setting. Preintubation videolaryngeal evaluation may identify those at risk for more significant intubation injury.

Abstract
This study retrospectively investigated the value of both endoscopically visible oropharyngeal secretions in the hypopharynx and swallowing frequency in the prediction of aspiration of food and liquid. Fiberoptic endoscopic evaluation of swallowing (FEES) was performed on a total of 69 individuals that included hospitalized elderly, nonhospitalized elderly, and young normal subjects. A four-level rating scale for determining the severity of accumulated oropharyngeal secretions was developed and employed to rate subjects prior to the presentation of food or liquid during the FEES. Spontaneous dry swallows were also counted during the observation period of the FEES. It was found that the accumulation of endoscopically visible oropharyngeal secretions located within the laryngeal vestibule was highly predictive of aspiration of food or liquid. There were significantly fewer spontaneous swallows in hospitalized subjects when compared with nonhospitalized subjects. There was also a significant decrease in the frequency of spontaneous swallows in aspirating hospitalized subjects when compared with nonaspirating hospitalized subjects. Results are discussed in terms of integrating this information with clinical bedside examination techniques.

Abstract
Even when performed by an experienced physician, endotracheal intubation is more traumatic than previously supposed. Following emergency intubation, patients have little probability of having a normal larynx. One-hundred patients underwent CT scan of the larynx 6 months or more following endotracheal intubation of short duration (up to 8 h). Ten patients (Group 1) with respiratory arrest underwent emergency intubation; 90 surgical patients (Group 2) underwent anesthesia with endotracheal intubation. Indirect laryngoscopy was performed in 59 symptomatic patients. Abnormal CT findings were present in 86 out of 100 patients. CT irregularities, which included tears, scars and small laryngoceles, were noted on indirect laryngoscopy in 59 symptomatic patients. The laryngeal damage following endotracheal intubation is surprisingly high.

Abstract
A new procedure for evaluating oropharyngeal dysphagia utilizing fiberoptic laryngoscopy was compared to the videofluoroscopy procedure. Twenty-one subjects were given both examinations within a 48-hour period. Results of the fiberoptic endoscopic evaluation of swallowing (FEES) and videofluoroscopy examinations were compared for presence or absence of abnormal events. Good agreement was found, especially for the finding of aspiration (90% agreement). The FEES was then measured against the videofluoroscopy study for sensitivity, specificity, positive predictive value, and negative predictive value. Sensitivity was 0.88 or greater for three of the four parameters measured. Specificity was lower overall, but was still 0.92 for detection of aspiration. It was concluded that the FEES is a valid and valuable tool for evaluating oropharyngeal dysphagia. Some specific patients and conditions that lend themselves to this procedure are discussed.
