RESUMO

OBJECTIVE: To evaluate the usefulness of premedication with 75 mg pregabalin orally to reduce the degree of preoperative anxiety in patients scheduled for plastic surgery procedures. METHOD: A controlled randomized double-blind clinical trial that analyzed two groups of patients: 75 mg pregabalin tablet (Pg) against placebo tablet (Pl). Efficacy was assessed using the visual anxiety scale (VAS) with two measurements, the first without medication and the second 70 minutes after the drug was taken. RESULTS: One hundred patients were evaluated, fifty received pregabalin and fifty placebo, baseline VAS score showed an general average of 4.6 ± 1.9 points, significantly higher in the Pg group (Pg 5.2 ± 2.1 points vs 4.1 ± 1.6 points Pl; p = 0.0035). The VAS score after premedication was 3.9 ± 2.1 points, significantly lower in the Pg group (Pg 3.2 ± 1.6 points vs 4.6 ± 2.3 Pl points, p = 0.0006). CONCLUSION: Premedication 75 mg pregabalin orally decreases the degree of preoperative anxiety in adult patients scheduled for plastic surgery procedures.

OBJETIVO: Evaluar la utilidad de la premedicación con 75 mg de pregabalina por vía oral como dosis única para disminuir el grado de ansiedad preoperatoria en pacientes sometidos a cirugía plástica. MÉTODO: Ensayo clínico controlado, prospectivo, aleatorizado, doble ciego, que analizó dos grupos de pacientes: pregabalina tableta de 75 mg (grupo Pg) contra tableta placebo (grupo Pl). La eficacia se evaluó utilizando la escala visual de ansiedad (EVa) con dos mediciones, la primera sin medicación y la segunda 70 minutos después de tomar la cápsula. RESULTADOS: Se evaluaron 100 pacientes: 50 que recibieron pregabalina y 50 placebo. La puntuación basal de la EVa mostró un promedio general de 4.6 ± 1.9 puntos, significativamente mayor en el grupo Pg (5.2 ± 2.1 puntos en Pg vs. 4.1 ± 1.6 puntos en Pl; p = 0.0035). El puntaje en la EVa posterior a la premedicación fue de 3.9 ± 2.1 puntos, significativamente menor en el grupo Pg (3.2 ± 1.6 puntos en Pg vs. 4.6 ± 2.3 puntos en Pl; p = 0.0006). CONCLUSIÓN: La premedicación con 75 mg de pregabalina disminuye el grado de ansiedad preoperatoria en pacientes que serán intervenidos de cirugía plástica.

RESUMO

In January 2020, a global pandemic was declared by the World Health Organization authorities for coronavirus disease 2019 (COVID-19). Since then, we have looked for ways to avoid transmission with mitigation measures and social distancing. However, areas with a high incidence of COVID-19 have struggled to maintain adequate supplies of personal protective equipment (PPE) essential for health workers. Many innovations have been proposed to assist providers including barriers to use during airway management. We present adaptations to previously described intubation or "aerosol" boxes.

RESUMO

BACKGROUND: Rhabdomyolysis is defined as skeletal muscle necrosis. Ultrasound assessment has recently become a useful tool for the diagnosis and monitoring of muscle diseases, including rhabdomyolysis. A case is presented on the ultrasound findings in a patient with rhabdomyolysis. OBJECTIVE: To highlight the importance of ultrasound as an essential part in the diagnosis in rhabdomyolysis, to describe the ultrasound findings, and review the literature. CLINICAL CASE: A 30 year-old with post-traumatic rhabdomyolysis of both thighs. Ultrasound was performed using a Philips Sparq model with a high-frequency linear transducer (5-10MHz), in low-dimensional scanning mode (2D), in longitudinal and transverse sections at the level of both thighs. The images obtained showed disorganisation of the orientation of the muscle fibres, ground glass image, thickening of the muscular fascia, and the presence of anechoic areas. CONCLUSIONS: Ultrasound is a useful tool in the evaluation of rhabdomyolysis.
