RESUMO
OBJECTIVE: To determine the motions produced during pediatric extrication when using a system of motion estriction and extrication. METHODS: Simulation-based biomechanical analysis study conducted with inertial sensors to measure motion produced in the cervical spine of a pediatric simulator during extrication from a vehicle. RESULTS: The mean of the movements was 3.5° (SD ±1.35°). The mean time was 4 minutes 1 second (SD, ±45.09 seconds). The mean rotation toward the right was 3.34° (SD ±3.52°) and toward the left 2.62° (SD ±2.26°). The mean for lateralization was 6.24° (SD ±3.20°) toward the right and 2.50° (DE ±2.76°) toward the left. The mean for flexion was 2.36° (SD ±2.10°) and for extension 4.21° (SD ±2.15°). CONCLUSIONS: The device analyzed allows for the extrication of the pediatric patient with high levels of motion restriction of the spinal column with the Pediatric Immobilization and Extrication System.

Objetivos: Comparar la autoextracción (AE) frente a la AE con collarines en sujetos con bajo riesgo de lesión cervical. Método: Estudio de simulación mediante análisis biomecánico con sensores inerciales, determinando la desalineación de la columna cervical durante la AE con y sin collarines cervicales. Resultados: El desequilibrio fue 3,12 (DE 34,62) grados mayor con el collarín STIFNECK (SN) (IC al 95% de -15,33 a 21,57; p =0,7234) que con AE y también 5,95 (DE 31,76) grados mayor con collarín X-COLLAR (XC) (IC al 95% de -10,98 a 22,87; p = 0,4654) que con AE. Cuando comparamos la AE con los diferentes tipos de collarines, observamos que con el collarín XC se produjeron 2,83 (DE 12,10) grados de desalineación más que con el collarín SN (IC al 95% de -3,62 a 9,27; p = 0,3650). Conclusiones: La desalineación de la columna cervical mediante la AE es similar a la provocada cuando se aplican collarines cervicales
Objective: To compare self-extraction with and without a cervical collar in subjects at low risk of cervical spine injuries. Methods: Simulation study analyzing biomechanical data from inertial sensors to detect misalignment of the cervical spine during self-extraction with and without a cervical collar. Results: Misalignment was a mean (SD) 3.12 (34.62) degrees greater during self-extraction with a Stiffneck collar in place (95% CI, -15.33 to 21.57 degrees; P=.7234) than during extraction without a collar. Misalignment was also greater, by 5.95 (31.76) degrees, with an X-collar in place (95% CI, -10.98 to 22.87; P=.4654) than without a collar. The between-collar comparison of differences showed that misalignment was 2.83 (12.10) degrees greater with the X-collar (95% CI, -3.62 to 9.27 degrees; P=.3650). Conclusion: Misalignment of the cervical spinal column is similar during self-extraction with or without a cervical collar in place

OBJECTIVES: To measure cervical spine movement during removal of a motorcycle helmet by health care professionals. MATERIAL AND METHODS: Observational study using biomechanical inertial sensors to detect movement in the spinal column during removal of helmets. RESULTS: Thirty-four emergency medicine specialists and nurses participated. The mean (SD) rotation was 1.14° (0.82°) to the left and 3.30° (1.69°) to the right (P<.001). Mean flexion was 9.82° (7.46°) and mean extension was 6.23° (6.86°) (P<.001). Mean lateral displacement was 5.73° (2.97°) to the left and 5.62° (8.22°) to the right (P=.678). The removal maneuvers took a mean of 70 seconds (4 seconds). CONCLUSION: Helmet removal was completed in an average of 70 seconds with flexion and rotation mainly toward the side where the professional supporting the head was positioned.

La flexoextensión fue de 9,82 (7,46)° para la flexión y de 6,23 (6,86)° para la extensión (p < 0,001). La lateralización fue de 5,73 (2,97)° para el lado izquierdo y de 5,62 (8,22)° para el lado derecho (p = 0,678). El tiempo medio de realización de la extracción fue 70 (4) seg. CONCLUSIONES: La extracción del casco se realizó en 70 segundos con flexión y rotación hacia el lado donde se encuentra colocado el profesional que sujeta la cabeza.
