Insights

Influenza A and B cause severe pediatric acute respiratory distress syndrome (PARDS) with high mortality (33%) and morbidity (15.5%). Young children and those previously healthy are at significant risk.

Area of Science:

  • Pediatric critical care medicine
  • Infectious diseases
  • Respiratory medicine

Background:

  • Pediatric acute respiratory distress syndrome (PARDS) is a severe condition.
  • Influenza virus is a known cause of respiratory illness in children.
  • The 2019-20 season saw significant influenza activity.

Purpose of the Study:

  • To investigate the clinical features of PARDS caused by influenza.
  • To analyze treatment strategies for influenza-related PARDS.
  • To determine the outcomes of children with influenza-related PARDS.

Main Methods:

  • Multicenter retrospective study.
  • Inclusion criteria: 1 month to 18 years diagnosed with PARDS associated with influenza during the 2019-20 season.
  • Data collected on clinical characteristics, treatment, and outcomes.

Main Results:

  • Sixty-seven patients were included; 60% were under 5 years old.
  • Influenza A (80.5%) and B (19.5%) were identified. Most patients (73.1%) had comorbidities.
  • 33% mortality and 15.5% morbidity were observed. Severe PARDS occurred in 52.5% of patients, with 86.6% requiring invasive mechanical ventilation.

Conclusions:

  • Both Influenza A and B cause severe PARDS with similar, high rates.
  • Influenza-related PARDS has a significant mortality (33%) and morbidity (15.5%) rate.
  • Previously healthy children, particularly those under 5, are vulnerable to severe outcomes.

Acute Respiratory Failure-IV01:23

Acute Respiratory Failure-IV

Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...

Acute Respiratory Failure-V01:29

Acute Respiratory Failure-V

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...

Acute Respiratory Failure-I01:21

Acute Respiratory Failure-I

Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...

Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Acute Respiratory Failure-III01:30

Acute Respiratory Failure-III

Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
