[Accidental strangulation in a perambulator--again].

Three cases of accidental strangulation of children in prams are described. One of the cases has been described previously. The reason for the strangulation lies in the construction of the pram, so that the actual lower frame is collapsible, and when this occurs, the handle is folded over the collapsed frame. In the cases described, the security mechanisms were insufficient and the children were strangled between the handle and the bassinet. This construction is considered unsuitable and prams with different constructions are recommended.
