A Randomized Clinical Trial on the Use of Antiseptic Solutions for the Pin-Site Care of External Fixators: Chlorhexidine-Alcohol Versus Povidone-Iodine.

Pin-site infections remain a common clinical complication in patients with external fixators. Pin-site care is commonly performed with either chlorhexidine-alcohol solution or povidone-iodine solution. This study aimed to investigate the superiority of chlorhexidine-alcohol solution versus povidone-iodine solution for external fixator pin-site care in pin-site infection. This prospective randomized clinical trial using an open, parallel-group design was conducted in a single Spanish hospital. Eligible consenting patients from November 2018 to May 2019 who underwent placement of an external fixator were included. Patients were randomly assigned to receive pin-site care using either a 2% chlorhexidine-alcohol solution or a 10% povidone-iodine solution. The primary endpoint was the development of a pin-site infection. In total, 568 pins were analyzed (128 patients, with a mean of 4.3 pins per patient). No significant differences were found between groups. However, statistically significant differences were found regarding time and infection variables. The longer the person had the fixator, the higher the risk of infection, t(x) = 5.49, p = .002. Both chlorhexidine-alcohol and povidone-iodine solutions are equally effective antiseptic agents for the prevention of infections in external fixators.

Variables to Predict Mortality in Hip Fractures in Patients Over 65 Years of Age: A Study on the Role of Anticoagulation as a Risk Factor.

The objective of this research was to study the possible relationship between the consumption of dicoumarinic agents (understanding the consumption of acenocoumarol as regulated and monitored anticoagulation) and the mortality rate in people older than 65 years undergoing a hip fracture (HF) intervention. It was a retrospective, observational and descriptive study. Nine hundred fifty-seven patients were included who underwent an intervention for HF between the years 2012 and 2014 in a third-level hospital. Patients took acenocoumarol (16.1%), which compared with nonanticoagulated patients took longer in receiving intervention, they remained hospitalized for more days, and they presented greater mortality within the first year after the intervention. Likewise, those who presented greater risk according to the classification system used by the American Society of Anesthesiologists (ASA) to estimate the risk of anesthesia for the different states of the patients who were anticoagulated also suffered greater mortality. The next factors increased the mortality in the first year: advanced age, delayed surgery, male sex, need for transfusion, high international normalized ratio, consumption of acenocoumarol, and a high ASA risk. We concluded the consumption of acenocoumarol increased the risk of mortality within the first year after surgery in 1.3 of possible cases. Other risk factors that also independently increased the risk of mortality included advanced age, male sex, delayed surgery, the need for transfusions, and surgical risk (for high levels in the ASA classification).

Prevalencia de úlceras por presión en pacientes sometidos a artrodesis de columna / Prevalence of pressure ulcers in patients undergoing an arthrodesis spine

Objetivos: Identificar la incidencia de úlceras por presión (UPP) en el quirófano en pacientes sometidos a artrodesis de columna realizadas en el intervalo de 2 años. Material y métodos: Diseño descriptivo, trasversal retrospectivo. Revisión de historias clínicas. Resultados: Se valoraron 269 pacientes, 52% mujeres, de una media de edad de 58,7 años. Las posiciones más frecuentes fueron decúbito supino y decúbito prono (34% ambas). La prevalencia de UPP fue del 14%, con un 51,4% de grado II, y la localización más frecuente fue tórax y frente. La mayor frecuencia de aparición fue a partir de las 4 horas de intervención, pero no hallamos relaciones significativas entre la aparición de úlceras por presión y otras variables. Conclusiones: Es necesario llevar a cabo estudios de intervención para prevenir UPP en el área quirúrgica, debido a que existe poca bibliografía al respecto. Por otro lado, la alta incidencia hallada nos hace plantearnos la necesidad de aumentar las medidas preventivas por parte de enfermería

Objectives: Identify the incidence of pressure ulcers (PU) in surgery in patients undergoing spinal fusion performed in the range of 2 years. Material and methods: Descriptive, transversal and retrospective design. Review of medical histories. Results: 269 patients were evaluated, 52% were women and the average age of 58.7 years. The most frequent were supine and prone positions (34% both). PU prevalence was 14%, with 51.4% grade II, the most frequent location was chest and forehead. The highest frequency of occurrence was from 4 hours intervention, but we have not significant relationships between pressure ulcers and other variables. Conclusions: It is necessary to carry out intervention studies to prevent PU in the surgical area, because there is little literature. On the other hand the high incidence found begs the need to increase preventive measures by nurses
