Assessment of respiration during video fluoroscopy of dysphagic patients

Nilsson, Håkan; Ekberg, Olle LU ; Bülow, Margareta LU and Hindfelt, Bengt (1997) In Academic Radiology 4(7). p.503-507
Abstract
RATIONALE AND OBJECTIVES: The authors evaluated the coordination of swallowing and respiration in dysphagic patients. MATERIALS AND METHODS: Video fluoroscopy and respirometry were performed simultaneously during 98 swallows in 33 patients (18 women, 15 men) with a median age of 70 years (interquartile range, 52-78 years). Pharyngeal transit time, deglutition apnea, and the ratio between the two (swallowing safety index) were calculated. Presence of a misdirected swallow (aspiration or penetration) was indicated. RESULTS: Pharyngeal transit time was not associated with deglutition apnea. Misdirected swallow was associated with a slightly prolonged pharyngeal transit time, a slightly shorter deglutition apnea, and a significantly lower... (More)
RATIONALE AND OBJECTIVES: The authors evaluated the coordination of swallowing and respiration in dysphagic patients.

Pharyngeal transit time, deglutition apnea, and the ratio between the two (swallowing safety index) were calculated. Presence of a misdirected swallow (aspiration or penetration) was indicated. RESULTS: Pharyngeal transit time was not associated with deglutition apnea. Misdirected swallow was associated with a slightly prolonged pharyngeal transit time, a slightly shorter deglutition apnea, and a significantly lower swallowing safety index (1.8 [1.0-4.2] vs 4.5 [2.4-6.7]; P < .001) compared with normally directed swallow. The association between misdirected swallow and lower swallowing safety index was independent of pharyngeal transit time. CONCLUSION: Assessment of respiration is important in the evaluation of dysphagia. Aspiration, especially in elderly dysphagic patients, may be a consequence of primarily disturbed respiration. A low swallowing safety index may indicate risk of misdirected swallow. (Less)
