Does body mass index influence the degree of pelvic tilt produced by a Crawford wedge?
A pelvic tilt of 15° is standard practice when positioning a woman for caesarean section, and is commonly produced by tilting the operating table or placing a wedge under the right hip. This study investigated whether body mass index affects the degree of pelvic tilt produced when a wedge is used. ⋯ Variability in pelvic tilt increased with body mass index and was greatest with a booking body mass index >35kg/m(2).
