Insights

Children with croup syndrome experience higher pulmonary arterial pressure, especially with severe symptoms. This elevated pressure is reversible with treatment, indicating the importance of monitoring during illness.

Area of Science:

  • Pediatric Pulmonology
  • Cardiology
  • Critical Care Medicine

Background:

  • Croup syndrome (laryngotracheitis) is a common cause of upper airway obstruction in children.
  • Upper airway obstruction in children can lead to elevated pulmonary arterial pressure.
  • The relationship between croup syndrome severity and pulmonary arterial pressure requires further investigation.

Purpose of the Study:

  • To investigate the association between croup syndrome and pulmonary arterial pressure in pediatric patients.
  • To compare pulmonary arterial pressure in children with croup syndrome versus healthy controls.
  • To assess the impact of croup severity on pulmonary arterial pressure.

Main Methods:

  • Echocardiography was used to measure pulmonary arterial pressure in 40 children with croup syndrome and 14 healthy controls.
  • Patients were categorized into high croup score (>=6) and low croup score groups.
  • High croup score patients received dexamethasone treatment, with serial measurements during therapy.

Main Results:

  • Children with croup syndrome exhibited significantly higher pulmonary arterial pressures compared to healthy subjects at diagnosis.
  • Patients with high croup scores had markedly elevated pulmonary arterial pressures versus the low croup score group (P < .05).
  • Pulmonary arterial pressure normalized by the end of therapy in all treated patients.

Conclusions:

  • Pulmonary arterial pressure increases in the acute phase of croup syndrome, correlating with disease severity.
  • The elevation in pulmonary arterial pressure associated with croup syndrome is reversible.
  • Doppler echocardiography is a valuable tool for monitoring pulmonary arterial pressure in children with croup syndrome.

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a stethoscope.
Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Pressure Relationships in Thoracic Cavity

Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs during...
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...
Blood Pressure01:24

Blood Pressure

The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...
