Resumen
La insuflación inadecuada durante las colonoscopias es común. Un nuevo dispositivo de sellado rectal, RECSEAL, maneja eficazmente las fugas de gas, mejorando la insuflación y la visualización del colon durante los procedimientos.
Área de la Ciencia:
- Gastroenterología
- Desarrollo de Dispositivos Médicos
- Endoscopia
Sus antecedentes:
- La insuflación inadecuada durante las colonoscopias, causada por fugas de gas, dificulta la visualización luminal.
- Una encuesta a gastroenterólogos reveló una tasa del 6.6% de insuflación inadecuada que requirió intervención.
Objetivo del estudio:
- Abordar la insuflación inadecuada en colonoscopias mediante el desarrollo de un nuevo dispositivo de sellado rectal.
- Evaluar la eficacia del dispositivo RECSEAL en el manejo de fugas de insuflación y la mejora de la visualización.
Principales métodos:
- Desarrollo del RECSEAL, un dispositivo de sellado rectal de silicona diseñado para una inserción y retención seguras en el canal anal.
- Evaluación del RECSEAL utilizando sensores de presión en entornos de banco, ex vivo (tono anal deficiente simulado) y in vivo (modelos en cerdos).
Principales resultados:
- El RECSEAL mantuvo presiones colónicas significativamente más altas (32-33 mm Hg) en comparación con los controles (0.3-3.6 mm Hg) en modelos de esfínter anal intacto y lesionado (P < .0001).
- El dispositivo demostró una mejor visualización del lumen en colonos colapsados.
- Se confirmó la viabilidad del RECSEAL en un modelo in vivo en cerdos.
Conclusiones:
- El RECSEAL flexible aumenta eficazmente la presión luminal en el colon.
- RECSEAL muestra potencial para mejorar la insuflación y visualización del colon durante las colonoscopias.

37.7K
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

01:27Assessing Body Temperature - Rectal
12.3K
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

1.5K
In most substances, the current flow is proportional to the voltage applied to it. A simple relationship between the values of current, voltage, and resistance is known as Ohm's law. Nonohmic devices do not exhibit a linear relationship between voltage and current. One such device is the semiconducting circuit element known as a diode. A diode is a circuit device that allows current flow in only one direction.
Consider a simple circuit consisting of a battery, a diode, and a resistor. A...

Appearance is a multidimensional aspect of self-presentation that encompasses observable attributes such as clothing, grooming, speech, and nonverbal behavior. These elements are often strategically managed to align with socially constructed expectations in different settings. For instance, individuals tailor their appearance during job interviews, social gatherings, or athletic events to meet the perceived norms of those environments.Contextual Adaptation and Social SignalsThe research...
