Cilostazol versus Aspirin or Clopidogrel for Reducing Post-Stroke Aspiration Pneumonia: A Nationwide Retrospective Cohort Study.

INTRODUCTION: The association between the use of cilostazol as a post-stroke antiplatelet medication and a reduction in post-stroke pneumonia has been suggested. However, whether cilostazol has a greater preventive effect against post-stroke aspiration pneumonia (AP) than other antiplatelet medications remains unclear. Thus, this study aimed to evaluate whether cilostazol has a greater preventive effect against post-stroke AP than aspirin or clopidogrel. METHODS: Through the Japanese Diagnosis Procedure Combination database, we identified patients who were hospitalized for ischemic stroke between April 2012 and September 2019. We performed 1:1 propensity score matching between patients who received cilostazol alone at discharge and those who received aspirin or clopidogrel alone at discharge. The primary outcome was the 90-day readmission for post-stroke AP. The occurrence of recurrent ischemic stroke within 90 days was also evaluated. RESULTS: Among the 305,543 eligible patients with ischemic stroke, 65,141 (21%), 104,157 (34%), and 136,245 (45%) received cilostazol, aspirin, and clopidogrel, respectively. Propensity score matching generated 65,125 pairs. The cilostazol group had a higher proportion of 90-day post-stroke readmissions with AP than the aspirin or clopidogrel groups (1.5% vs. 1.2%, p < 0.001). The proportion of patients with recurrent ischemic stroke within 90 days was also higher in the cilostazol group (2.4% vs. 2.2%, p = 0.017). CONCLUSION: The present study suggests that cilostazol may not have a greater effect on preventing post-stroke AP within 90 days than other antiplatelet medications. Nevertheless, further randomized controlled trials with longer follow-up periods are warranted.

Aspiration Pneumonia.

Aspiration pneumonia is a lower respiratory tract infection that results from inhalation of foreign material, often gastric and oropharyngeal contents. It is important to distinguish this from a similar entity, aspiration with chemical pneumonitis, as treatment approaches may differ. An evolving understanding of the human microbiome has shed light on the pathogenesis of aspiration pneumonia, suggesting that dysbiosis, repetitive injury, and inflammatory responses play a role in its development. Risk factors for aspiration events involve a complex interplay of anatomical and physiological dysfunctions in the nervous, gastrointestinal, and pulmonary systems. Current treatment strategies have shifted away from anaerobic organisms as leading pathogens. Prevention of aspiration pneumonia primarily involves addressing oropharyngeal dysphagia, a significant risk factor for aspiration pneumonia, particularly among elderly individuals and those with cognitive and neurodegenerative disorders.

Differences in residual volume above different tracheostomy tube cuffs depending on tube structure, tube tilt angle, and liquid viscosity.

INTRODUCTION: Proper management of aspirated material above the tracheostomy tube cuff is crucial to prevent complications, such as aspiration pneumonia. This study aimed to thoroughly examine the effects of aspirated liquid viscosity, suction port positioning, and tube tilt angle on residual volume above the cuff (RVAC). METHODS: Five types of tracheostomy tubes (approximately 9 mm outer diameter) were placed through a transparent cylinder with an inner diameter of 18 mm. The cuff was inflated to completely seal the interior of the cylinder. Four liquids with different viscosities were poured onto the cuff, and the liquid above the cuff was suctioned from the side port. The cylinder was angled at 90° and 20°, and each test was performed thrice to determine the average RVAC. RESULTS: After side-port suctioning, some liquid residue was observed on the cuff of all tracheostomy tubes. The RVAC increased with higher liquid viscosity. The tubes with a longer distance from the suction port opening to the cuff top exhibited more RVAC. Moreover, the RVAC was almost the same regardless of the cylinder angle for tubes with a suction port on the lateral side. However, tubes with backside ports showed a decreased RVAC with cylinder tilt. CONCLUSIONS: This study underscores the persistence of residual material on cuffed tracheostomy tubes even with regular subglottic secretion drainage. This emphasizes the need for specialized tracheostomy tube development aimed at reducing post-suction RVAC. Improved designs can potentially minimize complications associated with residue accumulation.

Aspiration prevention surgeries: a review.

BACKGROUND: Severe dysphagia can cause intractable pneumonia and lead to life-threatening conditions. Intractable aspiration can occur despite medical management for aspiration prevention. Surgical intervention is indicated for intractable aspiration to prevent potentially life-threatening complications. Since the 1970s, several surgical treatments to prevent aspiration have been reported, and various aspiration prevention surgeries have been introduced, but little is known about them or their benefits. This is a review of the types of aspiration prevention surgery, with the aim of increasing aspiration prevention surgery awareness and their clinical outcomes among medical professionals, which will guide the choices of aspiration prevention surgeries for patients with intractable aspiration. MAIN BODY: Aspiration prevention surgeries can be categorized into three according to their approaches: removal of the larynx, altering the structure of the trachea, and closure of the larynx. Aspiration prevention surgeries to remove the larynx include total and central-part laryngectomy. Aspiration prevention surgeries to alter the structure of the trachea include tracheoesophageal diversion, laryngotracheal separation, and the tracheal flap method. Surgeries to close the larynx can be divided into supraglottic laryngeal closure, glottic laryngeal closure, and subglottic laryngeal closure. Aspiration prevention surgeries prevent aspiration and increase oral intake in 50-80% of patients. Most patients lose vocal function after aspiration prevention surgeries; however, some patients who have undergone total laryngectomy or laryngotracheal separation restored their speech function through tracheoesophageal puncture and use of voice prosthesis. Postoperative suture failure is frequent after epiglottic flap closure and total laryngectomy but rare after central-part laryngectomy, laryngotracheal separation, glottic closure, and subglottic closure. Furthermore, aspiration prevention surgeries improve the quality of life of patients and their caregivers by decreasing suctioning frequency. CONCLUSIONS: In this review, we described the history and development of aspiration prevention surgeries. Medical professionals need to continually improve their knowledge and skills to facilitate appropriate aspiration prevention surgeries according to patient condition.

[Diagnostics and treatment of post-stroke dysphagia]. / Diagnostik und Therapie der Dysphagie nach einem Schlaganfall.

BACKGROUND: Post-stroke dysphagia is highly prevalent and leads to severe complications, such as aspiration pneumonia and malnutrition. Despite the high clinical relevance dysphagia management is heterogeneous and often inadequate. OBJECTIVE: The aim of this review article is to provide an overview of the diagnostic and treatment strategies for post-stroke dysphagia based on recent studies. MATERIAL AND METHODS: Narrative literature review. RESULTS: Dysphagia screening should be performed as early as possible in every stroke patient, e.g., with a simple water swallowing test or a multiconsistency protocol. Subsequently, flexible endoscopic evaluation of swallowing (FEES) is indicated in patients with abnormal screening results or existing risk factors for dysphagia. Dietary modifications, oral hygiene measures, and nutritional therapy can help reduce complications. Behavioral swallowing therapy or experimental therapies, such as neurostimulation procedures and pharmacological approaches aim to improve swallowing function and have shown promising results in studies. CONCLUSION: Timely management of dysphagia is necessary to reduce complications.

[Is oral care for dysphagic patients wasted time? A narrative review on the effects of oral care on pneumonia risk and guidelines for an effective and structured approach]. / Ist die therapeutische Mundpflege bei Dysphagiepatient*innen verschwendete Zeit? Ein narrativer Review zu Effekten der Mundpflege auf die Pneumoniehäufigkeit und Ableitung einer Handlungsempfehlung.

Aspiration pneumonia is a common cause of death in dysphagia patients. In this review, we investigate whether a structured oral care approach can help to reduce pneumonia risk in dysphagic patients. In addition, guidelines for the implementation of oral care on the basis of the analyzed studies are presented. Oral care has positive effects on the risk of pneumonia in dysphagia patients. Oral care should be based on the principles of simplicity, safety, efficiency and effectiveness, universality and economy and it should include all parts of the oral cavity. Effective oral care takes less than five minutes a day. The tactile stimulation prepares the patient for dysphagia therapy and can be considered wisely-invested time.

Effectiveness of Water Jelly Ingestion for Both Rehabilitation and Prevention of Aspiration Pneumonia in Elderly Patients With Moderate to Severe Dysphagia.

BACKGROUND AND AIMS: We evaluated the effectiveness of water jelly ingestion for both rehabilitation and the prevention of aspiration pneumonia in a retrospective analysis of elderly patients with moderate to severe dysphagia. PATIENTS AND METHODS: Study 1: consecutive patients with borderline ingestion in an endoscopic swallowing evaluation were enrolled (n=36, 18 men and 18 women: mean age 82±9 y) and categorized into a group with water jelly (50 to 100 mL) ingestion training 3×/day or an untrained control group. Their food intake levels were then compared using a Food Intake Level Scale. Study 2: consecutive patients who were hospitalized because of aspiration pneumonia were enrolled (n=64, 35 men and 29 women: mean age 81±9 y) and categorized into a group with cyclic ingestion of water jelly immediately after each meal or a control group. The incidence of aspiration pneumonia that was newly developed during hospitalization was compared between the groups. RESULTS: In study 1, 36 patients with a Hyodo-Komagane score of 8 were enrolled. Three of the 12 (25%) patients who underwent water jelly ingestion training were able to eat a pureed diet (level 5, 2 patients; level 6, 1 patient) while none of the 24 patients (0%) who did not undergo this training were able to eat any form of diet (levels 5 and 6, no patients) (P=0.011). In study 2, 64 patients were enrolled. No newly developed aspiration pneumonia was observed in the 34 patients (0%) who received cyclic water jelly ingestion, whereas 17% (5/30) of patients not receiving water jelly after meals newly developed aspiration pneumonia during hospitalization (P=0.031). CONCLUSIONS: Water jelly ingestion was effective for both rehabilitation and the prevention of aspiration pneumonia in elderly patients with moderate to severe dysphagia.

Long-term outcomes after surgery to prevent aspiration for patients with amyotrophic lateral sclerosis.

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects motor neurons selectively. In particular, weakness in respiratory and swallowing muscles occasionally causes aspiration pneumonia and choking, which can be lethal. Surgery to prevent aspiration, which separates the trachea and esophagus, can reduce the associated risks. Central-part laryngectomy (CPL) is a relatively minimally invasive surgery to prevent aspiration. No studies have been conducted on the long-term outcomes of surgery to prevent aspiration in patients with ALS. This case series aimed to determine the long-term outcomes of surgery to prevent aspiration and the use of a continuous low-pressure aspirator in patients with ALS by evaluating the frequency of intratracheal sputum suctions performed per day, intra- and postoperative complications, oral intake data, and satisfaction of patients and their primary caregiver to predict improvement in patients' quality of life (QOL). METHODS: We report a case series of six patients with ALS who underwent CPL along with tracheostomy to prevent aspiration between January 2015 and November 2018. We evaluated their pre- and postoperative status and administered questionnaires at the time of last admission to the patients and their primary caregivers. RESULTS: The mean follow-up period after CPL was 33.5 months. Aerophagia was a common postoperative complication. The use of a continuous low-pressure aspirator resulted in reduced frequency of intratracheal sputum suctions. All cases avoided aspiration pneumonia. Oral intake was continued for 2-4 years after the tracheostomy and CPL. The satisfaction levels of the patient and primary caregiver were high. CONCLUSION: Our case series suggests that the use of a continuous low-pressure aspirator in patients undergoing CPL improves oral intake and reduces the frequency of intratracheal sputum suctions, which improves the QOL of patients with ALS and their families and caregivers. CPL and continuous low-pressure aspiration should be considered as a management option for ALS with significant bulbar and respiratory muscle weakness/dysfunction.

Outcomes of Aspiration Prevention Surgery: A Retrospective Cohort Study Using a Japanese Claims Database.

Aspiration prevention surgeries, such as laryngotracheal separation and total laryngectomy are performed to prevent aspiration pneumonia. We aimed to investigate the outcomes of surgery for intractable aspiration and relevant factors. This retrospective cohort study used a nationwide insurance claims database that included company employees and their family members aged < 75 years in Japan. We extracted the data of patients who underwent aspiration prevention surgeries between January 2005 and March 2019. We identified 127 patients (males, 55.9%), of whom 59.8% were aged < 18 years at the surgery. The most common comorbidity was neurological disease (99.2%). The frequency of pneumonia episodes decreased by 1.5 per year after surgery compared with before surgery (p < 0.001). Among patients who received parenteral and enteral nutrition before surgery (n = 92), the adjusted hazard ratio (aHR) for oral intake without parenteral and enteral nutrition was lower in the longer preoperative duration (≥ 14.7 months) for the parenteral and enteral nutrition. However, the difference was not statistically significant (aHR 0.55; 95% confidence interval: 0.15-2.08, p = 0.38). The aHR for oral intake was higher in the ≥ 30 years group than in the < 30 years group (aHR 13.76; 95% confidence intervals: 4.18-42.24; p < 0.001). This study demonstrated that postoperative oral intake was achieved more frequently in patients aged ≤ 30 years than in those aged > 30 years, and supported the effectiveness of aspiration prevention surgery for reducing aspiration pneumonia. Further research is necessary to investigate factors related to postoperative oral intake.

[Laboratory study on bacteriological aspects of beverages and thickeners for dysphagia patients : Growth survey of Escherichia coli on thickeners and beverages]. / Laborstudie zu bakteriologischen Aspekten von Getränken und Andickungsmitteln für Dysphagiepatienten : Wachstumserhebung von Escherichia coli auf Andickungsmitteln und Getränken.

BACKGROUND: Currently, there is little evidence-based guidance on bacteriological aspects of thickeners or beverages for dysphagia patients in Germany that can be recommended to prevent aspiration pneumonia. Therefore, the aim of this study was to evaluate the lowest cell amount of E. coli on M9 agar media with beverages and thickeners. METHODOLOGY: In the laboratory experiment 1 · 107 cells of E. coli were plated on a defined minimal medium (M9 agar plates) with different carbon sources and incubated at 37 °C for 2 days. The increase in cell number was determined using a photometer. Carbon sources were water, beer, orange juice, thickened beer, maltodextrin-xanthan gum-based thickeners, corn starch-based thickeners and potato starch-based thickeners. RESULTS: The lowest E. coli cell amount was measured on water compared to beer, orange juice and all thickeners. A higher E. coli cell count was measured on maltodextrin-based thickeners than on potato starch-based and corn starch-based thickeners. DISCUSSION: In the present laboratory experiment, no individual risk factors for the development of aspiration pneumonia in humans were considered; however, initial bacteriological evidence for dysphagia patients could be collected. Due to the high growth of E. coli on maltodextrin, yeast, fructose and glucose, these ingredients should be used with caution by dysphagia patients. Further research on thickeners and beverages is needed to make a comprehensive recommendation for action in this aspect.

[Integration and Promotion of a Care Model for Chewing and Swallowing Reconstruction Teams].

Eating with the mouth is one of the basic joys of life. However, some 450,000 people currently live with nasogastric tubes in Taiwan. The causes of dysphagia disorders are complicated. Caring effectively for these cases requires interdisciplinary medical cooperation. Taiwan is expected to become a super-aged society in 2025. In Taiwan, people over 65 years old, residents of long-term care institutions, and stroke cases experience high rates of dysphagia. Every case of dysphagia has a potential risk of aspiration pneumonia, with pneumonia ranking as the third leading cause of death in people over 65 years old. Therefore, this issue demands the attention and assistance of medical care personnel. The integrated care model used at Kaohsiung Siaogang Hospital to promote the reconstruction of dysphagia functions is introduced in this article to help give medical teams interested in assisting cases a deeper understanding of this model. Integrating the resources and manpower of multiple disciplines helps cases improve dysphagia functions and reduces the need for indwelling nasogastric tubes and the incidence of aspiration pneumonia. Let us protect the everyday happiness of eating and improve quality of life.

[Preventive Care for Aspiration Pneumonia in Patients With an Indwelling Nasogastric Tube].

More than 190,000 patients have been fitted with an indwelling nasogastric tube in Taiwan. Nasogastric tube feeding is a strategy for temporary or long-term feeding and for preventing aspiration pneumonia in patients with dysphagia. However, aspiration pneumonia is a common complication in patients fitted with a nasogastric tube. Displacement of the nasogastric tube, inappropriate length of the placed nasogastric tube resulting gastroesophageal reflux, inappropriate feeding posture and speed, and excessive gastric residual volume resulting in vomiting are important risk factors associated with aspiration pneumonia. In this article, the literature and clinical practice experiences were reviewed to identify methods used to confirm the length and positioning of nasogastric tubes. We further explored strategies for preventing oral-care and tube-feeding-induced aspiration pneumonia during the period of indwelling nasogastric tube. These strategies included adjusting the patient's positions for receiving tube feedings, feeding techniques, methods and frequency of gastric residual volume measurement, and conditions for stopping nasogastric feeding. This exploration was intended to provide nursing staff with relevant knowledge and skills for preventing aspiration pneumonia in patients with indwelling nasogastric tube to improve patient safety.

Poor oral hygiene, oral microorganisms and aspiration pneumonia risk in older people in residential aged care: a systematic review.

BACKGROUND: aspiration pneumonia increases hospitalisation and mortality of older people in residential aged care. OBJECTIVES: determine potentially pathogenic microorganisms in oral specimens of older people with aspiration pneumonia and the effect of professional oral care in reducing aspiration pneumonia risk. DATA SOURCES: PUBMED/MEDLINE, CINAHL, EMBASE, COCHRANE, PROQUEST, Google Scholar, Web of Science. STUDY ELIGIBILITY CRITERIA: published between January 2001 and December 2019 addressing oral microorganisms, aspiration pneumonia, oral health and treatment. PARTICIPANTS: people 60 years and older in residential aged care. STUDY APPRAISAL AND SYNTHESIS METHODS: the Newcastle-Ottawa Scale and the Standard Protocol Items: Recommendations for Intervention Trials checklist. RESULTS: twelve studies (four cross-sectional, five cohort and three intervention) reported colonisation of the oral cavity of older people by microorganisms commonly associated with respiratory infections. Aspiration pneumonia occurred less in people who received professional oral care compared with no such care. Isolation of Candida albicans, Staphylococcus aureus, methicillin-resistant S. aureus and Pseudomonas aeruginosa was related to mortality due to aspiration pneumonia. An interesting finding was isolation of Escherichia coli, a gut bacterium. LIMITATIONS: more information may be present in publications about other co-morbidities that did not meet inclusion criteria. A high degree of heterogeneity prevented a meta-analysis. Issues included sampling size, no power and effect size calculations; different oral health assessments; how oral specimens were analysed and how aspiration pneumonia was diagnosed. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: pathogenic microorganisms colonising the oral microbiome are associated with aspiration pneumonia in older people in residential care; professional oral hygiene care is useful in reducing aspiration pneumonia risk.

Routine point-of-care ultrasound (POCUS) assessment of gastric antral content in traumatic emergency surgical patients for prevention of aspiration pneumonitis: an observational clinical trial.

BACKGROUND: Polytrauma patients are at a higher risk of delayed gastric emptying. To assess the gastric volume, a reliable diagnostic tool is needed to prevent the occurrence of aspiration pneumonia, which remains a serious complication associated with anesthesia. Gastric antral ultrasound can provide reliable information about the size of the gastric antrum in traumatized patients undergoing emergency surgery. METHODS: A prospective observational study of 45 polytrauma patients undergoing emergency surgery under general anesthesia was carried out. Prior to induction of anesthesia in the emergency department, gastric ultrasound was performed for qualitative and quantitative assessment of the gastric antrum in a supine position and right lateral decubitus (RLD) position. This was followed by routine placement of the nasogastric tube to aspirate and calculate the volume of the stomach contents. RESULTS: Of the 45 polytrauma patients, the risk assessment of aspiration and the anesthesia technique changed in 14 patients (31.1%) after the gastric ultrasound examination. A very good relationship existed between the expected stomach volume at the RLD position and the suction volume in the nasogastric tube. In all cases, no aspirations were documented. CONCLUSION: Ultrasound examination of the stomach in polytrauma patients allows assessing the size and type of stomach contents. The data obtained can influence the choice of anesthesia technique and reduce the risk of aspiration pneumonia. TRIAL REGISTRATION: This trial was registered at ClinicalTrials.gov . registry number: NCT04083677 on September 6, 2019.

Tongue cleaning in the elderly and its role in the respiratory and swallowing functions: Benefits and medical perspectives.

Oral dysfunction, including oral uncleanness and decline in tongue motor function, tongue pressure and swallowing function, precedes frailty. The tongue's dorsum is a reservoir of oral microbiota, desquamated epithelial mucosa and leukocytes due to the multi-papillate anatomy, and leads to tongue coating. The tongue coating is frequently found in older adults because of hyposalivation, immunity's hypoactivity, diminished motor function and compromised tongue's pressure with age. Anaerobe-driven volatile sulphur compounds in tongue coating are a major cause of intra-oral malodor. Dysbiosis of the tongue-coating microbiome rather than the amount of microorganisms is associated with a risk of aspiration pneumonia. Daily tongue cleaning with a brush or scraper is an easy way to control tongue coating deposits and quality. Using mouth wash or rinse-containing germicides is also a way to control the microbiota of tongue coating. The tongue function is closely related to swallowing. Tongue and suprahyoid muscles are linked with respiratory muscles through the endothoracic fascia. The mechanical stimulation during the cleaning of the tongue may stimulate the respiratory muscles. An intervention trial revealed that tongue cleaning by mucosal brush improves tongue pressure, swallowing and respiratory function in old residents of nursing homes, suggesting a rehabilitative effect of tongue cleaning on the swallowing and respiratory functions, preventing aspiration pneumonia. This narrative review assesses the tongue-cleaning benefits for respiratory and swallowing functions and the possibility of preventing aspiration pneumonia.

Transition to adult care for young people with cerebral palsy.

Cerebral palsy (CP) is associated with a high burden of comorbid respiratory disease subsequent to multiple risk factors associated with increasing levels of disability. Correspondingly, respiratory disease is the leading cause of death in CP, including amongst young people who are transitioning or who have just transitioned between paediatric and adult healthcare services. Therefore, consideration of both preventive and therapeutic respiratory management is integral to transition in patients with CP, as summarised in this review.

A Pilot Study of Pharyngeal Electrical Stimulation for Orally Intubated ICU Patients with Dysphagia.

OBJECTIVE: Dysphagia is a common disorder in neurological and non-neurological intensive care unit (ICU) patients and can lead to aspiration pneumonia, prolonged ventilation, and delayed extubation. Dysphagia is an independent predictor of increased mortality. In dysphagic stroke patients with tracheotomy, the use of pharyngeal electric stimulation (PES), an emerging technique to treat dysphagia, has been shown to improve airway protection and shorten time to decannulation. The objective of this study was to determine whether patients who receive PES have a lower prevalence of pneumonia and frequency of reintubation. DESIGN: Secondary analysis of a non-blinded interventional subject sample from a large clinical study with a historical age, pathology, and severity-matched control group. SETTING: ICU of a tertiary care medical center. PATIENTS: In this pilot non-blinded study, a group of 15 intubated patients in a general and a neurologic ICU received PES while orally intubated during ICU stay. A control group (n = 25) matched for age, type, and region of pathology, and severity of illness expressed by Simplified Acute Physiology Score and Therapeutic Intervention Scoring System was used to compare for pneumonia and need for reintubation. MAIN RESULTS: Patients treated with PES had significantly lower prevalence of pneumonia (4 vs 21, p = 0.00046) and frequency of reintubation (0 vs 6, p = 0.046) when compared to controls. CONCLUSION: Although limited by its small size and non-blinded design, this is the first study demonstrating the benefits of PES in ICU patients still orally intubated, thus offering a potential new method to reduce morbidity, mortality, and economic burden in a mixed ICU population. In order to further investigate and strengthen our findings, a statistically powered, randomized controlled study is recommended.

Complications associated with tracheoesophageal voice prostheses from 2010 to 2020: A MAUDE study.

PURPOSE: Tracheoesophageal puncture with voice prosthesis placement remains the gold standard for voice restoration following total laryngectomy, but may cause various complications. This study aims to summarize patient-related and device-related adverse events associated with tracheoesophageal puncture and voice prosthesis placement. MATERIALS AND METHODS: The U.S. Food and Drug Administration's Manufacturer and User Facility Device Experience database was queried for reports of adverse events related to tracheoesophageal puncture with voice prosthesis placement from January 1, 2010, to April 30, 2020. Data were extracted from reports pertaining to tracheoesophageal prostheses. RESULTS: Seventy-seven reports involving tracheoesophageal voice prostheses were identified, from which 111 adverse events were extracted. Of these, 58 (52.3%) were patient-related, while 53 (47.7%) were device-related. The most frequently reported patient-related adverse events were aspirated prosthesis (24 [41.4%]), foreign body during placement (11 [19.0%]), aspiration pneumonia (9 [15.5%]), and aspirated brush tip (8 [13.8%]). The most common device-related adverse events were detached brush tip (15 [28.3%]), leak (14 [26.4%]), and torn esophageal flange (11 [20.8%]). CONCLUSIONS: While tracheoesophageal puncture with voice prosthesis placement has revolutionized voice rehabilitation following total laryngectomy, the procedure may be associated with adverse events both at the time of placement and later. Interventions aimed at improving both physician and patient education may help reduce adverse events attributed to improper use. Further research is needed to clarify optimal approaches to education.

A Comparative Study of Two Tube Feeding Methods in Patients with Dysphagia After Stroke: A Randomized Controlled Trial.

BACKGROUND: Dysphagia is a common symptom seen in stroke patients, it not only affects patients' nutrition supply, but also causes aspiration pneumonia. To solve the problem of nutritional support for patients with dysphagia after stroke, nasogastric tubes are routinely indwelling to provide nutrition in China. However, this feeding method sometimes causes food reflux, aspiration, pneumonia, and often affects the patients' comfort and self-image acceptance. AIM: The aim of this study was to determine whether a new feeding method called intermittent oroesophageal (IOE) tube feeding compared with continuous nasogastric tube feeding as a practical and beneficial mean of decreasing the rate of stroke associated pneumonia (SAP), and improving patients' swallowing function, comfort, psychological status. DESIGN: This was an assessor-blinded, single-center, randomized controlled trial. METHODS: Ninety-seven hospitalized stroke patients with dysphagia in the rehabilitation department from January to December 2018 were randomized to a control group and an intervention group. Patients in both groups received routine nursing, rehabilitation treatment and swallowing therapy. Patients in the intervention group were given IOE tube feeding, while those in the control group were fed by indwelling nasogastric tube. Outcomes were assessed at admission, discharge or the end of the tube feeding. RESULTS: The incidence of SAP in the intervention group was 16.33% lower than that (31.25%) in the control group; the comfort score (2.08 ± .64), anxiety score (10.98 ± 2.28), depression score (7.39 ± 2.16) were lower than those (3.02 ± .70), (12.10 ± 2.18), (8.42 ± 2.34) in the control group. The improvement rate of swallowing function in the intervention group was 83.67% higher than that (66.67%) in the control group (all P < .05). CONCLUSIONS: The IOE tube feeding compared with continuous tube feeding may reduce the incidence of SAP, and improve patients' swallowing function, comfort, psychological status in patients with dysphagia after stroke.

Aspiration pneumonia and pneumonitis: a spectrum of infectious/noninfectious diseases affecting the lung.

PURPOSE OF REVIEW: Our purpose is to describe aspiration pneumonia/pneumonitis as a spectrum of infectious/noninfectious diseases affecting the lung. We summarize diagnosis, risk factors, treatment, and strategies for prevention of aspiration. RECENT FINDINGS: Aspiration is present in normal individuals, and disease manifestation depends on the chemical characteristics, frequency, and volume of inoculum. Anaerobes, though present, are no longer the predominant microbes isolated in aspiration pneumonia. Targets for preventing aspiration including improved oral hygiene and positional feeding have had mixed results. Patients diagnosed by clinicians with aspiration pneumonia experience greater morbidity and mortality than patients with community-acquired pneumonia. SUMMARY: Aspiration pneumonia and pneumonitis are part of the pneumonia continuum and share similarities in pathophysiology, microbiology, and treatment. Modern microbiology demonstrates that the lung is not sterile, and isolates in aspiration pneumonia frequently include aerobes or mixed cultures. Treatment for aspiration pneumonia should include antibiotic coverage for oral anaerobes, aerobes associated with community-acquired pneumonia, and resistant organisms depending on appropriate clinical context. Additional studies targeting prevention of aspiration and investigating the increased morbidity and mortality associated with aspiration pneumonia are warranted.
