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 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...

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.

Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Cardiopulmonary Resuscitation II: ACLS Airway Management01:22

Cardiopulmonary Resuscitation II: ACLS Airway Management

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...

Summary

Sudden upper-airway obstruction can cause acute pulmonary edema with bleeding. This condition, often presenting as bloody fluid from the mouth or nose, typically resolves within 24 hours.

Area of Science:

  • Pulmonary Medicine
  • Emergency Medicine
  • Pediatrics

Background:

  • Sudden severe upper-airway obstruction can precipitate acute hemorrhagic pulmonary edema.
  • This complication is observed in hospital settings.
  • Other causes of acute pulmonary hemorrhage are rare in young children.

Purpose of the Study:

  • To review and analyze case reports of acute hemorrhagic pulmonary edema following upper-airway obstruction.
  • To identify the common presenting features and clinical course of this condition.

Main Methods:

  • A comprehensive review of 197 published case reports.
  • Analysis of presenting symptoms, onset, and resolution times.

Main Results:

Published on: October 2, 2014

  • The primary presenting feature is expectoration of blood-stained fluid from the airways (larynx, mouth, nose).
  • This occurs in 10-15% of cases of sudden, severe, but non-lethal, upper-airway obstruction.
  • Signs appear within minutes to hours after obstruction relief and resolve within 12-24 hours.

    • Conclusions:

    • The presence of blood in or from the mouth/nose in a distressed child suggests acute pulmonary edema.
    • Sudden upper-airway obstruction is the most common cause in this scenario.
    • Prompt recognition and management are crucial for favorable outcomes.
