ABSTRACT

OBJECTIVE: This study was designed to evaluate the performance of a pelvic restraint cushion (PRC), a submarining countermeasure that deploys under the thighs when a crash is detected in order to block the forward motion of the pelvis. METHODS: Sled tests approximating low- and high-speed frontal impacts were conducted with 4 female postmortem human subjects (PMHS) restrained by a lap and shoulder belt in the right front passenger seat. The subjects were tested with and without a PRC. RESULTS: The PRC is effective in reducing forward motion of the PMHS pelvis and reduces the risk of injury due to lap belt loading in a high-speed frontal crash. CONCLUSIONS: Although small sample size limits the utility of the study's findings, the results suggest that the PRC can limit pelvic forward motion and that pelvic injury due to PRC deployment is not likely.

ABSTRACT

Se analizan 106 casos de síndrome de obstrucción de vena cava superior (SOVCS) atendidos en el Hospital de Oncología del Centro Médico Nacional, Instituto Mexicano del Seguro Social, de 1961 a 1981. El diagnóstico se estableció sobre bases clínicas: edema de cara y cuello, ingurgitación yugular y disnea de reposo en todos los casos; 90 por ciento de ellos mostraron ensanchamiento mediastinal en las telerradiografías de tórax, y 98.4 por ciento tuvieron etiología neoplásica. Las entidades más frecuentes fueron cáncer broncógeno y linfomas. El tratamiento instituido consistió en radioterapia en 73.1 por ciento de los casos, radioterapia y quimioterapia en 21.7 por ciento y quimioterapia en 5 por ciento. En 85 por ciento de los pacientes tratados se logró mejoría de los síntomas. La supervivenia a un año en todos los casos fue de 22 por ciento
