Epistaxis01:30

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Tracheostomy Suctioning I: Pre-Procedural Steps

Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...
Suctioning the Oropharyngeal Airway01:25

Suctioning 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...

    Summary

    High frequency ultrasound (HFU) can guide wound care for sinus wounds, which lack evidence-based treatment guidelines. This technology helps clinicians select appropriate dressings, improving patient outcomes.

    Area of Science:

    • Wound healing research
    • Medical imaging applications

    Background:

    • Wound management relies on clinical expertise, but evidence for sinus wound dressings is scarce.
    • Lack of evidence complicates treatment selection, potentially leading to inappropriate therapies for sinus wounds.

    Observation:

    • Sinus wounds present a significant challenge in wound management due to limited evidence-based treatment options.
    • High frequency ultrasound (HFU) offers a potential tool to assess sinus wound characteristics.

    Findings:

    • HFU can provide valuable data to guide clinical decisions regarding sinus wound management.
    • A case study demonstrated HFU's utility in informing the choice of wound dressing for a patient with a sinus wound.

    Implications:
