Insights

A case of nasal myiasis caused by Sarcophaga peregrina flies was identified in a hospitalized patient after mechanical ventilation. This infestation highlights potential hospital-acquired infections and the importance of monitoring patients with nasotracheal tubes.

Area of Science:

  • Medical Entomology
  • Infectious Diseases
  • Clinical Case Report

Background:

  • Hospital-acquired infections pose significant risks to patient recovery.
  • Nasal myiasis, infestation by fly larvae in the nasal cavity, is uncommon in hospital settings.
  • Mechanical ventilation via nasotracheal intubation can create opportunities for opportunistic infections.

Observation:

  • A 74-year-old male patient developed nasal myiasis during hospitalization for non-ST-elevation myocardial infarction.
  • The patient had an indwelling nasotracheal tube for 8 days following coronary arterial bypass surgery.
  • Seven maggots were retrieved from the patient's nostrils post-extubation.

Findings:

  • The retrieved larvae were identified as Sarcophaga peregrina (fly).
  • The clinical timeline and fly life cycle suggest a hospital-acquired infestation.
  • This case represents nasal myiasis in a critically ill patient requiring prolonged intubation.

Implications:

  • This case underscores the need for vigilance regarding potential myiasis in intubated patients.
  • Environmental and patient hygiene protocols in hospitals may require review to prevent such infestations.
  • Early detection and management of nasal myiasis are crucial to prevent complications.

Endotracheal Intubation II: Nursing Management01:17

Endotracheal Intubation II: Nursing Management

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...
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.

Endotracheal Intubation I: Procedure01:15

Endotracheal Intubation I: Procedure

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...
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...
Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
