Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding01:15

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

1.6K
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Enteral Nutrition I: Orogastric and Nasogastric Feeding

2.4K
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...

Upper GI Series: Barium Swallow

2.2K
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Deglutition01:25

Deglutition

7.7K
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...

Summary
This summary is machine-generated.

Laryngeal closure (LC) improved oral intake in multiple system atrophy (MSA) patients with dysphagia, unlike tracheostomy (TR). LC offers a better management strategy for swallowing disorders in MSA patients.

Area of Science:

  • Neurology
  • Otolaryngology
  • Gastroenterology

Background:

  • Multiple system atrophy (MSA) patients often require surgical interventions like tracheostomy (TR) and aspiration prevention.
  • Limited research exists on the postoperative outcomes for MSA patients undergoing these procedures.
  • Effective management strategies for dysphagia and respiratory issues in MSA are needed.

Purpose of the Study:

  • To evaluate the efficacy of tracheostomy (TR) versus laryngeal closure (LC) in managing dysphagia and respiratory disorders in multiple system atrophy (MSA) patients.
  • To determine the optimal surgical approach for improving swallowing function and oral intake in MSA.

Main Methods:

  • Retrospective analysis of 18 MSA patients (2001-2014) who underwent tracheostomy (n=11) or laryngeal closure (n=12).
  • Assessment of vocal fold impairment, dysphagia severity (using Penetration Aspiration Scale - PAS), and oral intake.
  • Comparison of postoperative outcomes, including swallowing function and survival time, between TR and LC groups.

Main Results:

  • Tracheostomy (TR) did not improve swallowing function (PAS scores) in any patient and worsened it in seven out of eleven.
  • Laryngeal closure (LC) enabled all patients to regain partial or complete oral intake post-surgery.
  • No significant difference in postoperative survival time was observed between the TR and LC groups.

Conclusions:

  • Laryngeal closure (LC) is a favorable surgical option for managing severe dysphagia in multiple system atrophy (MSA) patients.
  • LC demonstrates superior outcomes in restoring oral intake compared to tracheostomy (TR) in this patient population.
  • Surgical intervention choice should prioritize functional swallowing and oral feeding in MSA management.
