Respiratory distress and Arnold-Chiari malformation
Neurology
|January 1, 1981
Summary
Arnold-Chiari malformation in children can cause breathing and swallowing problems. Postmortem studies revealed brainstem vascular lesions, suggesting damage from the malformation shortens survival.
Area of Science:
- Neurology
- Pediatric Medicine
- Pathology
Background:
- Arnold-Chiari malformation is a structural defect in the cerebellum.
- Affected children often present with neurological deficits.
Purpose of the Study:
- To investigate the neuropathological findings in children with Arnold-Chiari malformation.
- To correlate clinical symptoms with postmortem examination results.
Main Methods:
- Retrospective analysis of 14 pediatric cases with Arnold-Chiari malformation.
- Clinical history review focusing on respiratory, vocal, and swallowing functions.
- Postmortem examination of brainstem structures, particularly the medulla oblongata.
Main Results:
- Twelve of fourteen children showed vascular lesions in the medulla oblongata tegmentum.
- Clinical histories included respiratory distress, apnea, vocal cord paralysis, and dysphagia.
- Survival was significantly shorter in children with these clinical and pathological findings.
Conclusions:
- Arnold-Chiari malformation may lead to vascular supply alterations in the brainstem.
- Stretching of arteries due to herniation can cause irreversible brainstem damage.
- This damage can result in life-threatening respiratory dysfunction and reduced survival.

Skeletal Muscle Relaxants: Therapeutic Uses
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...
Other Pulmonary Disorders
Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
Respiratory System Abnormal Finding I: Inspection and Percussion
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

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-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 causing...
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...
