Abstract:
Objective To compare 76% meglucamine diatrizoate solution with 60%barium sulphate suspen-sion for use in videofluoroscopic swallowing studies(VFSSs).Methods Forty-nine cases of dysphagia caused by brain injury.brainstem lesion ir nasopharyngeal carcinoma(NPC)were recruited for this study.They were divided into a meglucamine diatrizoate group of 22 patients who were administered 76% meglucamine diatrizoate solution as a contrast agent,and a barium sulphate group of 27 patients with whom 70%barium sulphate suspension was used.All the Datients were treated by balloon dilatation and other routine dysphagia rehabilitation procedures.The treatment end point was either the patient's resuming an oral diet or after 4 weeks of treatment. All cases were evaluated by VFSS pre-and post-treatment.Results The patients in the meglucamine diatrizoate group showed significant pre-and post-treatment differences in terms of the pharynx transit times of brain injury and brainstem lesion victims.NPC patients showed no significant differences.In the barium sulphate group there were significant pre-and post-treatment differences in Dharynx transit time for patients with all three conditions. Conclusions Using 76%meglucamine di-atrizoate solution as a contrast agent decreases the sensitivity of VFSS. Using 60% barium sulphate suspension in VFSS is recommended.
