Morbilidad respiratoria en los partos prematuros tardíos
JAMA
|July 29, 2010
Resumen
Los partos prematuros tardíos aumentan significativamente el riesgo de síndrome de dificultad respiratoria y otros problemas respiratorios en los recién nacidos. Este estudio pone de relieve la necesidad de atención especializada para estos bebés en comparación con los partos a término.
Área de la Ciencia:
- Neonatología Neonatología.
- Perinatología Perinatología.
- Pulmonología Pediátrica.
Sus antecedentes:
- Los partos prematuros tardíos (34-36 semanas) representan una proporción creciente de los nacimientos prematuros.
- Estos bebés a menudo experimentan enfermedades a corto plazo, especialmente problemas respiratorios, que requieren cuidados intensivos y estadías hospitalarias prolongadas.
Objetivo del estudio:
- Evaluar y comparar la morbilidad respiratoria a corto plazo en los bebés prematuros tardíos frente a los bebés a término.
- Utilizando una cohorte contemporánea de entregas estadounidenses para evaluar los riesgos contemporáneos.
Principales métodos:
- Análisis retrospectivo de datos electrónicos de salud de 12 instituciones estadounidenses (2002-2008).
- La inclusión de 233.844 partos, con una revisión detallada de la gráfica para los recién nacidos ingresados en la UCIN por compromiso respiratorio.
- Se utilizó regresión logística multivariada para comparar los resultados entre los bebés prematuros tardíos y los bebés a término, controlando los factores de confusión.
Principales resultados:
- Los bebés prematuros tardíos mostraron tasas significativamente más altas de admisión a la UCIN y compromiso respiratorio en comparación con los bebés a término.
- La incidencia de síndrome de dificultad respiratoria, taquipnea transitoria del recién nacido, neumonía e insuficiencia respiratoria fue notablemente mayor en los bebés prematuros tardíos.
- Los ratios de probabilidad ajustados indicaron un riesgo sustancialmente mayor de estas afecciones en los bebés nacidos entre las 34 y 37 semanas de gestación en comparación con las 39 y 40 semanas.
Conclusiones:
- El parto prematuro tardío se asocia con un riesgo significativamente elevado de síndrome de dificultad respiratoria y otras morbilidades respiratorias.
- Estos hallazgos subrayan la vulnerabilidad de los bebés prematuros tardíos y la necesidad de atención médica adecuada.

01:05Breathing
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...
01:21Acute 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:

01:17Pulmonary 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...
01:30Acute 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...
01:19Respiratory Assessment: Purpose and Indications
Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...

01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
