MEDSPEAK

A clinical sign used to detect minimal amounts of ascites.

Method The patient is placed on all fours–hands and knees; the belly is bobbed from below. The lower limits of detection of ascites is 1-1.5 litres in the supine patient, in whom a “blubbery” fluid wave is detectable by striking a flank on one side and palpating the “splash” on the other, or by moving a stethoscope from the most dependent position gradually contralaterally.
