Summary
Oropharyngeal dysphagia has many causes, from aging to stroke. Early assessment and tailored interventions, including speech therapy and new technologies, are key to managing aspiration risk and improving swallowing function.
Area of Science:
- Neurology
- Gastroenterology
- Otolaryngology
Background:
- Oropharyngeal dysphagia stems from diverse factors including aging, neurological conditions, and post-surgical changes.
- It can lead to malnutrition, dehydration, and acute aspiration pneumonia, often polymicrobial.
- Odontogenic infections may exacerbate bacterial load in aspiration pneumonia.
Purpose of the Study:
- To review the broad etiology and pathophysiology of oropharyngeal dysphagia.
- To discuss current diagnostic methods for aspiration risk assessment.
- To explore various intervention and rehabilitation strategies, including emerging therapies.
Main Methods:
- Review of scientific literature on oropharyngeal dysphagia.
- Discussion of diagnostic tools: bedside evaluation, videofluoroscopy, and fiberoptic endoscopic evaluation of swallowing.
- Exploration of therapeutic approaches: speech-language pathology, surgical options, neuroplasticity, and neuromuscular stimulation.
Main Results:
- Etiology is multifactorial, impacting neural control and oropharyngeal musculature.
- Diagnostic evaluations are crucial for identifying aspiration risk.
- Interventions are patient-specific, encompassing therapy, surgery, and novel techniques.
Conclusions:
- Effective management of oropharyngeal dysphagia requires accurate diagnosis and individualized treatment plans.
- Emerging strategies like neuroplasticity and external neuromuscular stimulation offer promising avenues for rehabilitation.
- Understanding the interplay between oral health and aspiration pneumonia is critical.

01:26Enteral Nutrition I: Orogastric and Nasogastric Feeding
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

01:25Suctioning the Oropharyngeal Airway
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

01:26Esophageal Strictures-II: Clinical Features and Management
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

01:21Barrett Esophagus-II: Clinical Manifestations and Management
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

01:25Deglutition
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

01:30Esophageal Strictures-I: Introduction
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
