Endotracheal Intubation I: Procedure01:15

Endotracheal Intubation I: Procedure

6.5K
Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

Endotracheal Intubation II: Nursing Management

2.2K
Endotracheal intubation is a critical procedure that can be lifesaving for many patients with respiratory distress or failure. The role of nursing in managing endotracheal tubes is pivotal, as it involves pre-intubation preparation, assisting during the procedure, and post-extubation care.
1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...

Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

Enteral Nutrition I: Orogastric and Nasogastric Feeding

986
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...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

370
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Tracheostomy Care I: Pre-procedural Steps01:16

Tracheostomy Care I: Pre-procedural Steps

811
A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.

Tracheostomy Suctioning II: Procedure01:23

Tracheostomy Suctioning II: Procedure

1.2K
Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Summary

Veterinarians face occupational hazards when placing nasogastric tubes in horses, risking aspiration pneumonia from ingesting stomach contents or medications. Safer alternatives to mouth use are recommended to mitigate these risks.

Area of Science:

  • Veterinary Medicine
  • Occupational Health and Safety

Background:

  • Nasogastric intubation in horses is a critical procedure but poses significant occupational risks to veterinarians.
  • The use of the mouth to manipulate nasogastric tubes is a common practice among equine practitioners.

Purpose of the Study:

  • To assess and specify the potential occupational hazards associated with nasogastric intubation in horses.
  • To identify high-risk scenarios and substances encountered during the procedure.

Main Methods:

  • An online questionnaire was distributed to 123 equine veterinarians.
  • The survey collected data on practices, perceived risks, and exposure incidents during nasogastric tube placement.

Main Results:

  • A majority of veterinarians reported using their mouths to handle nasogastric tubes (sucking/blowing air) and accidental ingestion/aspiration of gastric contents or medications.
  • Risks increase with specific conditions like fever, diarrhea (potential Salmonella, Clostridium difficile), suspected poisoning (e.g., zinc phosphide), and when using mineral oil.
  • Lack of routine disinfection of nasogastric tubes further elevates infection risks.

Conclusions:

  • Veterinarians are exposed to serious health risks, including aspiration pneumonia, pneumonitis, and toxic gas inhalation, from nasogastric intubation practices.
  • Alternatives to mouth use, such as lavage, large syringes, or suction pumps, should be considered, particularly in high-risk cases.
  • Increased awareness and implementation of safer techniques are crucial for mitigating occupational hazards in equine veterinary practice.
