The Sheba Medical Center Protocol for Bedside Evaluation of Swallowing Disorders Among Tracheotomized Patients.

Abstract

The Sheba Blue Dye Test Protocol (SBDTP) is a swallowing bedside evaluation for tracheotomized patients (TP). It is based on the Modified Evans' Blue Dye Test (MEBDT), but includes several modifications that aim to overcome previously described caveats of the traditional MEBDT. These modifications include evaluating the patient three times, with increasing quantities of bolus. The purpose of this study was to examine the rates of positive and negative results of TP undergoing the SBDTP, in comparison to the MEBDT, which, generally, consists of a single evaluation. The study included a cohort of 39 TP admitted to the Sheba general hospital with various background diseases. Findings indicated that the percentage of positive results increased significantly from the first (18%) to the last stage (46.2%) of the SBDTP. This result demonstrated the advantage of the SBDTP as a more reliable evaluation for tracing aspiration among TP, especially in cases where access to instrumental examination is limited.
