Retención urinaria postoperatoria; Consideraciones anestésicas y perioperatorias
Postoperative Urinary Retention: Anesthetic and Perioperative Considerations
Baldini, Gabriele M.D., Bagry, Hema M.D., F.R.C.A., F.R.C.P.C., Aprikian, Armen M.D., F.R.C.S.C., Carli, Franco M.D., M.Phil., F.R.C.A., F.R.C.P.C.
Anesthesiology May 2009 - Volume 110 - Issue 5 - pp 1139-1157
Urinary retention is common after anesthesia and surgery, reported incidence of between 5% and 70%. Comorbidities, type of surgery, and type of anesthesia influence the development of postoperative urinary retention (POUR). The authors review the overall incidence and mechanisms of POUR associated with surgery, anesthesia and analgesia. Ultrasound has been shown to provide an accurate assessment of urinary bladder volume and a guide to the management of POUR. Recommendations for urinary catheterization in the perioperative setting vary widely, influenced by many factors, including surgical factors, type of anesthesia, comorbidities, local policies, and personal preferences. Inappropriate management of POUR may be responsible for bladder overdistension, urinary tract infection, and catheter-related complications. An evidence-based approach to prevention and management of POUR during the perioperative period is proposed.

Factores de riesgo para retención urinaria en pacientes hospitalizados
Risk factors of post-operative urinary retention in hospitalised patients.
HANSEN, B. S., SØREIDE, E., WARLAND, A. M. and NILSEN, O. B.
Acta Anaesthesiologica Scandinavica, 2011;55: 545-548. doi: 10.1111/j.1399-6576.2011.02416.x
Background: Post-operative urinary retention (POUR) is most accurately determined by using ultrasound to measure bladder volume. The aim of this study was to define the risk factors of POUR in the recovery room in hospitalised patients. Methods: An ultrasound-determined bladder volume ≥400 ml at arrival in the recovery room was used to define POUR. Multivariate regression analysis was used to identify patient and system factors linked to POUR in 773 consecutive hospitalised patients who had undergone orthopaedic, abdominal, gynaecological or plastic surgery without an indwelling urinary catheter. Results: We found the incidence of POUR to be 13%. The lack of pre-operative voiding, use of regional anaesthesia, anaesthesia time >2 h and emergency surgery were all independent risk factors for POUR. Conclusions: The detected incidence of POUR at arrival in the recovery room was rather high but had easily identifiable risk factors. We recommend pre-operative voiding whenever possible. Routine bladder scanning at arrival in the recovery room should be considered, especially after spinal anaesthesia, emergency surgery or when the anaesthesia time exceeds 2 h.

Validez cuantitativa de un instrumento


Validez cuantitativa de un instrumento

1. Validez de contenido (Validez Cualitativa)
La validez de contenido intenta evaluar la capacidad del instrumento para recoger el contenido y el alcance del constructo. Podemos dividirlo en tres fases según el estado actual del conocimiento
a. Aproximación a la población (Validez de respuesta)
b. Juicio de expertos (Validación por jueces)
c. Revisión del conocimiento disponible (Validez racional)
2. Consistencia interna (Alfa de Cronbach)
Es la capacidad de obtener resultados independientes de las circunstancias accidentales de la medición. Se fundamenta en la varianza de la variable medida, existen varios índices que miden confiabilidad, entre ellos el Alfa de Cronbach y el Kuder-Richardson (KR-20). Es afectado por la heterogeneidad de los individuos evaluados; cuanto más heterogéneo es el grupo, mayor es el coeficiente de fiabilidad.
3. Validez de constructo (Rotación de Varimax)
Debemos establecer probabilísticamente grupos de ítems que deberán ser definidos como dimensiones. Estas dimensiones deben ser conceptualizadas de manera consensuada para otorgarles el carácter de útiles y científicamente válidos, por cuanto no existe una prueba patrón. Si los dominios se han construido teóricamente, la estadística corrobora la idoneidad de estas agrupaciones.
4. Criterio (Índice Kappa)
Cuando la variable medida cuenta con un Gold Standard, entonces se puede verificar los resultados hallados, mediante un procedimiento. Si el criterio se fija en el presente, se habla de validez concurrente (los resultados del instrumento se correlacionan con el criterio en el mismo momento o punto del tiempo). Si el criterio se fija en el futuro, se habla de validez predicativa.
5. Estabilidad (ANOVA)
La medición debe arrojar valores constantes siempre que sean tomadas en condiciones similares entre una medición y otra (test-retest). Se trata de ver, hasta qué punto un conjunto de medidas son reproducibles en el tiempo, el grado en que las puntuaciones son estables sería el grado de fiabilidad, propiedad que solo puede ser evaluada si un constructo está plenamente definido.
6. Rendimiento (Curvas ROC)
El objetivo es optimizar el instrumento para reducir el error a la hora de emitir juicios de valor para tomar decisiones. Se construye una curva en base a los pares ordenados de sensibilidad y 1-especificidad en distintos puntos de corte del instrumento. Debemos elegir el puto de corte que nos ofrezca los mayores valores de sensibilidad y especificidad a través de las Curvas de ROC.
