Filter by:Post-operative dysphagia is a significant issue following anterior cervical spine surgery. The investigators are studying the effects of perioperative 3% sodium chloride, given over a period of 24 hours, on post-operative dysphagia. The goal is to reduce the incidence and severity of post-operative dysphagia.
The researchers wish to investigate whether proton pump inhibitors, administered prior to or after surgery, can reduce the incidence and/or severity of difficulty swallowing foods and/or liquids,following anterior cervical surgery.
Few existing data currently indicates that anti-inflammatory drugs could help diminish the local cervical inflammation tough to cause the dysphagia, hoarseness and dyspnea after an anterior surgical approach to the spine. This study aims to evaluate the effect of high dose of steroids on dysphagia after an anterior cervical spine procedure. Patients subjected to a cervical spine surgery through an anterior approach will be randomized to a treatment group receiving 3 doses of IV dexamethasone (decadron) and a placebo group receiving saline. Outcome will be measured with dysphagia scales, modified barium swallow and rhino-pharyngo-laryngoscopy, all done pre and post-operatively. Secondary outcomes involve neurological condition, pain and fusion rate.
It is the purpose of this study to determine if a commercially available electronic stethoscope synchronized with an smart phone or iPad application can be used as an accurate and objective screening tool for measuring dysphagia. The investigators plan to do so in two phases; in Phase I the investigators will recruit normal subjects to establish normal swallowing patterns, as well as optimal sensor placement; and in Phase II the investigators will compare the recordings obtained by the electronic stethoscope with those obtained using videofluoroscopy.
Cancers located in the upper aerodigestive tract of the head and neck region present unique management challenges due to the crucial functions in this anatomic region along with its anatomic density. As such, cancers themselves and the actual treatment can affect these functions. Of these, the ability to effectively and safely transport a swallow bolus from the oral cavity to the esophagus is particularly important. This consideration has in fact been a major source of debate regarding the optimal management for head and neck cancers as both oncologic-effective and function-preserving therapies are desired. Accomplishing this therapeutic goal has been elusive and can be attributed to a lack of tools that effectively and longitudinally evaluate swallow function over the course of a treatment and in follow-up. As such, investigators surprisingly lack a clear understanding of the natural history of treatment -related swallow dysfunction (dysphagia) regardless of the treatment modality. As such, understanding the prevalence of this significant complication is in fact not well established. Understanding the true prevalence of treatment-related dysphagia is in fact critical to establish as it will help guide decisions as to whether or not treatment strategies require modification including de-intensification of treatment that is receiving considerable attention for favourable prognosis patients associated with the human papillomavirus (HPV). To address this problem, winvestigators hypothesize that the quantitative and validated patient-reported outcome (PRO) instrument, the Sydney Swallow Questionnaire (SSQ), can be an effective tool to longitudinally measure swallow function to determine the natural history of head and neck cancer treatment-related swallow dysphagia. The SSQ is particularly well suited for longitudinal evaluation of swallow function as it quantifies various aspect of patient-perceived swallow function in contrast to other swallow PROs that measure the impact of swallow function on quality of life domains. To determine the two-year prevalence of dysphagia, investigators will employ a multi-institution prospective study design using our Oncospace® web-portal to facilitate secure prospective data curation and analysis that will include evaluations before, during and following standard of care definitive cancer treatment for a total of 36 months in the follow-up period.
The purpose of this study is to conduct a randomized clinical trial to compare the incidence of dysphagia in patients receiving general anesthesia with and without an endotracheal tube for Upper gastrointestinal endoscopy. If the incidence of dysphagia is found to be increased following endotracheal intubation for this procedure it could influence the investigators practice as anesthesiologists and may mandate the future routine use of laryngeal tracheal application of lidocaine at the time of intubation for example.
It was well known that aspiration is the primary cause of an aspiration pneumonia among the dysphagia patients. In order to predict the degree of an aspitation,video-fluoroscopic-swallowing study and fiberoptic-endoscopic swallowing evaluation have been developed, but those evaluations are invasive and allowed only in a limited condition. In this study, as a precedent study for the non-linear analysis, voice analysis using LPC method will be evaluated. The superiority of LPC method will be compared with a spectral analysis using Jitter and Simmer as a positive control. This clinical study will be performed prospective, positive-controlled, single-blind (i.e. assessor-blind),and single cohort clinical trial for efficacy
Radiotherapy plays an important role in the curative treatment of head and neck cancer. This treatment however is associated with significant acute and late toxicity with xerostomia and dysphagia severely implicating the patient's quality of life. With highly conformal radiotherapy techniques it is possible to decrease de dose to the organs at risk while maintaining adequate doses to the tumour. In order to adequately register the effect of these techniques it is imperative to obtain standardized information on the acute and late treatment effects. With this study the investigators want to evaluate this toxicity using standardized and validated questionnaires during follow-up. This data will then be correlated to the doses delivered to the specific organs at risk.
It was well known that long term intubation caused a various kind of abnormal presentations of dysphagia such as the increased aspiration risk, the decreased gag reflex, mucosal pathology, the airway stenosis and so on. It was thought that the freezing and impaired proprioception to be developed as a result of dis-use around the pharynx and the larynx while intubation was one of the reason. Preemptive swallowing manual stimulation applied on the oral cavity to avoid the vicious cycle of dis-use was reported to improve dysphagia after extubation. Neuromuscular electrical stimulation have been utilized for a wide variety of dysphagia of multiple causes of neuro-muscular disorder. Supposing that preemptive transcutaneous neuromuscular electrical stimulation to be delivered to the muscles of being involved in swallowing could decrease the degree of dis-use during intubation so that it could reduce the occurence and severity of dysphagia developed after extubation, the investigators plan to perform randomized prospective double blind placebo controlled clinical interventional study.
High Resolution Manometry is a new technology that utilizes 36 solid state sensors on a thin catheter spaced at 1-cm intervals. One can more effectively measure the pressure of the esophagus. It includes a sophisticated software to display the pressures data as color topography plot using time, length of the esophagus and pressure within the entire esophagus. It is unclear if this technology improvement actually correlates with patient's symptoms.
