“…A number of studies report or mention other types of containment used while patients are in PICU care: medication (coerced or rapid tranquillisation or PRN, see Table 1) ; seclusion (Brown & Bass 2004;Cohen & Khan 1990;Ford & Whiffin 1991;Hafner, Lammersma, Ferris, & Cameron 1989;Khan, Cohen, Chiles, Stowell, Hyde, & Robbins 1987;Michalon & Richman 1990;O'Brien & Cole 2004;Wynaden et al 2001); special observation (Citrome, Green, & Fost 1994;Hyde & Harrower-Wilson 1996); mechanical restraint (Cohen & Khan 1990;Khan, Cohen, Chiles, Stowell, Hyde, & Robbins 1987;Michalon & Richman 1990). The general impression conveyed is that such measures are used more frequently within a PICU environment than on general acute wards, and this impression is confirmed by the one study offering comparative information (Brown & Bass 2004), showing greater use of rapid tranquillisation and seclusion.…”
