The aim of this study was to determine whether the risk and severity
of penetration-aspiration with mixed consistency (MIX), which consists of cooked
rice and thin liquid barium (LIQUID), are different from the risks and severities
with each single consistency (cooked rice or LIQUID) in dysphagic patients.
DESIGN: Dysphagic patients (N = 29) performed a videofluoroscopic swallowing
study with the following foods: cooked rice, LIQUID, and MIX. Several components
were analyzed using recorded videotapes. RESULTS: The Penetration-Aspiration
Scale score for MIX was significantly lower than that for LIQUID (P < 0.016). The
location of the leading edge at the onset of a pharyngeal swallow between MIX and
LIQUID was not different (P = 0.705). The pharyngeal delay time of LIQUID was
delayed significantly compared with that of MIX (0.142 +/- 0.267 and -0.149 +/-
0.096 sec, respectively, P < 0.016). The severity of pharyngeal residue among the
foods was different according to the location. CONCLUSIONS: Swallowing of MIX is
not dangerous, and it is safer for not inducing penetration-aspiration as
compared with the swallowing of LIQUID. The risk of penetration-aspiration may be
judged depending on not only a food's consistency but also on various factors
that affect airway protection, including the texture of food.
