Accidents in developing countries are frequent and have high mortality and
morbidity rates. In Brazil, in 1995-1996, the year of this study, life supp
orting first aid (LSFA), which includes cardiopulmonary resuscitation (CPR)
basic life support (BLS) was not taught in schools. With the population of
165 million, the only way to teach the adult population on a large scale w
ould be by television (TV), that is widely viewed. This study compares two
groups of factory employees - 86 controls without TV exposure to LSFA and 1
16 exposed to brief LSFA skill demonstrations on TV. Their ability to acqui
re eight LSFA skills was evaluated: external hemorrhage control; immobiliza
tion of a suspected forearm fracture: treatment of a skin burn by cold flus
h; body alignment after a fall; positioning for shock and coma: airway cont
rol by backward tilt of the head; and CPR (steps A-B-C). Simulated skill pe
rformance on the evaluating nurse or manikin was tested at 1 week, 1 month,
and 13 months. In the control group, 1-31% performed individual skills cor
rectly; as compared to 9-96% of the television group (P < 0.001). There was
excellent retention over 13 months. Over 50% of the television group perfo
rmed correctly five of the eight skills, including positioning and hemorrha
ge control. Television viewing increased correct airway control performance
from 5 to 25% of trainees, while it remained at 3% in the control group. C
PR-ABC performance, however, was very poor in both groups. We conclude that
a significant proportion of factory workers can acquire simple LSFA skills
through television viewing alone, except for the skill acquisition of CPR
steps B (mouth-to-mouth ventilation) and C (external chest compressions) wh
ich need coached manikin practice. (C) 2000 Elsevier Science Ireland Ltd. A
