Exploración de las causas de pérdida de agujas de sutura mediante simulación y análisis de elementos finitos
AORN journal
|February 25, 2026
Resumen
La pérdida de agujas quirúrgicas, a menudo por portagujas caídos, es una preocupación de seguridad. Los estudios demuestran que al dejar caer los portagujas se abren, liberando agujas, y los cambios de diseño podrían mejorar la seguridad.
Área de la Ciencia:
- Seguridad Quirúrgica; Ingeniería Biomédica; Ciencia de Materiales
Sus antecedentes:
- La pérdida intraoperatoria de agujas de sutura presenta riesgos, prolongando los procedimientos y comprometiendo la seguridad del paciente.; Este problema ocurre comúnmente cuando se dejan caer los portagujas y se abren involuntariamente.
Objetivo del estudio:
- Investigar los mecanismos primarios detrás de la pérdida intraoperatoria de agujas.; Identificar los factores contribuyentes y proponer soluciones para mitigar los eventos de pérdida de agujas.
Principales métodos:
- Una encuesta nacional de 3649 enfermeras de quirófano (OR).; 1500 simulaciones controladas de caída de portagujas.; Análisis de elementos finitos (FEA) para modelar la dinámica de impacto.
Principales resultados:
- La transferencia de instrumentos, específicamente la caída de portagujas, fue identificada como la causa de pérdida por el 75,4% de las enfermeras.; Las caídas simuladas resultaron en la apertura inesperada del portagujas en el 30,6% de los casos, particularmente al aterrizar planos o sobre el anillo.; El FEA indicó que la deformación inducida por el impacto del anillo de sujeción desengancha los dientes de bloqueo, causando la liberación; los portagujas más grandes/pesados aumentaron el riesgo de apertura y la velocidad de la aguja.
Conclusiones:
- La caída de portagujas es la causa principal de la pérdida intraoperatoria de agujas.; El diseño del portagujas (por ejemplo, refuerzo del anillo de sujeción, dientes de bloqueo más profundos) y las superficies acolchadas pueden reducir los eventos de pérdida.; La implementación de modificaciones de diseño y protocolos de manejo puede mejorar significativamente la seguridad perioperatoria.

Mismatch Repair
Overview
Mismatch Repair
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

Shear and Bending Moment Diagram: Problem Solving
When analyzing a beam supporting concentrated loads and a distributed load, drawing the shear and bending moment diagrams is essential. These diagrams help understand the internal forces and moments acting on the beam, which is crucial for designing safe and efficient structures. Follow these steps to create the shear and bending moment diagrams:
Draw a Free-Body Diagram: Start by drawing a free-body diagram of the entire beam, including the concentrated loads, distributed load, and reaction...

Bending of Curved Members - Strain Analysis
The mechanics of deformation in curved members, such as beams or arches, under bending moments, involve complex responses. When such a member, symmetric about the y-axis and shaped like a segment of a circle centered at point C, is subjected to equal and opposite forces, its curvature and surface lengths change significantly. This alteration results in the shift of the curvature's center from C to C', indicating a tighter curve.
The important part of bending analysis for such a member is the...

Beams with Unsymmetric Loadings
Analyzing a supported beam under unsymmetrical loadings is essential in structural engineering to understand how beams respond to varied force distributions. This analysis involves calculating the deflection and identifying points where the slope of the beam is zero, which are crucial for ensuring structural stability and functionality.
The first moment-area theorem determines the slope at any point on the beam. This theorem indicates that the change in slope between two points on a beam...

Boundary Conditions: Lossless Lines
Consider a single-phase, two-wire, lossless transmission line terminated by an impedance at the receiving end and a source with Thevenin voltage and impedance at the sending end. The line, with length, has a surge impedance and wave velocity determined by the line's inductance and capacitance.
At the receiving end, the boundary condition states that the voltage equals the product of the receiving-end impedance and current. This relationship is expressed as a function of the incident and...
