Fluid diet - moderately thick
This document is part of the ACI Diet Specifications for Adult Inpatients. It is not to be used for patient education.
Aim
To provide thickened fluids of a moderately thick consistency for patients with dysphagia for whom thinner fluids are unsafe, and to maintain fluid balance using thickened fluids.
Characteristics
Level 400 – moderately thick is similar to the thickness of room-temperature honey. It is cohesive and pours slowly. It is possible to drink directly from a cup, although fluid flows very slowly. It is difficult to drink through a straw, even if using a wide bore straw. Spooning the liquid into the mouth may be the best way of taking this fluid.
Testing scales for viscosity exist, but are not formalised or standardised. Subjectively, fluids at this thickness slowly drip in dollops through the prongs of a fork.
Indications
Swallowing disorders identified by a speech pathologist, such as those associated with stroke, degenerative diseases (including multiple sclerosis, Parkinson’s disease and Guillain-Barré syndrome), and changes to the tongue, palate or pharynx that affect swallowing.
Nutritional adequacy
Care must be taken to ensure adequate fluid intake when thickened fluids replace unmodified fluids. Small quantities should be offered every one or two hours.
Precautions
No water jug to be left at bedside. Ensure all liquids available to the patient are thickened to the level determined by the speech pathologist. Patients with uncoordinated oral muscles have difficulty controlling the flow of liquid, which can easily enter the airway and lungs, leading to infection.
Paediatrics
Suitable for use in paediatrics when combined with an age-appropriate diet.
