Because the danger is so remote any safety device that is to gain ...

We constructed experimental equipment resembling bus stanchions and handrails and examined the grip and hold strength exerted when used. The total number of subjects was 80: 30 elderly and 19 young males, and 22 elderly and 9 young females. The experimental equipment comprised four parts: a hand...

A well fixed endotracheal tube is essential for safety during general anesthesia. In maxillofacial surgeries, securely fixing a nasotracheal tube in place has always been problematic. The aim of this article is to describe a simple but effective technique to fasten the nasotracheal tube using a wire support that allows a full range of head movement without interference in the surgical field.

A survey of Ohio nursing homes was conducted in 2007 to examine whether injury rates were related to facility characteristics and availability of safety equipment. The median rate of injury in the 898 facilities was 5.7 injuries per 100 workers per year. Although 95% of the facilities had written resident lift-ing policies, only 22% of these were zero-lift policies. Gait transfer belts(99%) and...
