Los humidificadores de habitación como fuente de infecciones por Acinetobacter
JAMA
|February 21, 1977
Resumen
Las infecciones por Acinetobacter calcoaceticus en veinticuatro pacientes se relacionaron con humidificadores de habitación sin calefacción. La eliminación de los humidificadores contaminados terminó con éxito el brote, destacando una medida de control ambiental crucial.
Área de la Ciencia:
- Enfermedades infecciosas Enfermedades infecciosas.
- Salud Ambiental Salud del medio ambiente.
- Microbiología Microbiología.
Sus antecedentes:
- Las infecciones sistémicas causadas por Acinetobacter calcoaceticus representan una preocupación significativa para la salud pública.
- La identificación de las fuentes de infecciones nosocomiales o adquiridas en la comunidad es fundamental para un control efectivo.
Objetivo del estudio:
- Para investigar la fuente de un grupo de infecciones por Acinetobacter calcoaceticus.
- Determinar el papel de los factores ambientales en la transmisión de Acinetobacter calcoaceticus.
Principales métodos:
- Investigación epidemiológica de veinticuatro casos de infección por Acinetobacter calcoaceticus durante cuatro meses.
- Evaluación ambiental para identificar posibles fuentes de infección, centrándose en el equipo de cabecera del paciente.
Principales resultados:
- Acinetobacter calcoaceticus fue identificado como el agente causal en veinticuatro infecciones sistémicas.
- Los humidificadores de habitaciones sin calefacción utilizados en las camas de los pacientes estuvieron implicados como la fuente en seis casos.
- La eliminación de los humidificadores implicados condujo al cese de nuevas infecciones.
Conclusiones:
- Los humidificadores de habitaciones sin calefacción pueden servir como un depósito y vehículo de transmisión para Acinetobacter calcoaceticus.

01:26Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...

01:22Healthcare Associated Infections II: Preventive Measures
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

01:30Pneumonia 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...

01:29Microbiota 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...
01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
01:29Pneumonia I: Introduction
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
