Performing a TS in TKA in patients with osteoarthrosis does not result in a relevant lower postoperative pain, or in an improvement in HRQOL, and it does increase the amount of bleeding after the procedure.
Determinar si el uso de almidón en la artroplastia de cadera es un factor de riesgo para el sangrado transquirúrgico excesivo y el uso de concentrados eritrocitarios. Método: Estudio retrospectivo observacional analítico de 240 pacientes sometidos a artroplastia total de cadera primaria desde enero de 2015 hasta enero de 2016. Se integraron dos grupos: almidón (94 pacientes) y no almidón (146 pacientes). Se analizaron la edad, el sexo, el índice de masa corporal, la hemoglobina prequirúrgica y posquirúrgica, el uso de concentrados eritrocitarios y el sangrado transquirúrgico. resultados: El grupo con almidón tuvo mayor riesgo de sangrado transquirúrgico excesivo (odds ratio [OR]: 3.58; intervalo de confianza del 95% [IC 95%]: 2.05-6.26) y de transfusión de concentrados eritrocitarios (OR: 3.12; IC 95%: 1.76-5.5). En el grupo con almidón hubo una media de sangrado transquirúrgico de 396 ml (desviación estándar [DE]: ± 234.94) y una disminución de la hemoglobina de 4.6 g/dl (DE: ± 1.38); en el grupo de no almidón hubo una media de sangrado de 271.8 ml (DE: ± 139.22) y una disminución de la hemoglobina de 3.34 g/dl (DE: ± 1.4). discusión: Los pacientes con almidón presentaron mayor sangrado transquirúrgico y requirieron en más ocasiones la transfusión de hemoderivados que los del grupo control, por lo que sugerimos considerar las posibles complicaciones relacionadas con el uso de hidroxietilalmidón.
Treatment for prosthetic knee replacement is becoming more common. Infection is an arthroplasty-related complication leading to prolonged hospitalization, multiple surgical procedures, permanent loss of the implant, impaired function, impaired quality of life and even amputation of the limb. Previous studies have evaluated the risk factors associated with periprosthetic knee infection, but scarce information related to risk factors associated with amputation in this group of patients is available. The purpose of this study was to identify risk factors for amputation in periprosthetic infected knee through a case-control study, analyzing patients treated from January 2012 to November 2016 in a hospital with a high incidence of this diagnosis. We included 183 patients with periprosthetic knee infection; 23 required amputation as definitive management (cases). We found that patients with surgical time >120 min (p = 0.01), surgical risk higher than two points according to the American Society of Anesthesiology score (p = 0.00), smokers (p = 0.04), obesity and diabetes mellitus (p = 0.00) had an increased risk of amputation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
