Fluid diet - mildly 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 mildly thick consistency for patients with dysphagia for whom thinner fluids are unsafe, and to maintain fluid balance using thickened fluids.
Characteristics
Level 150 – mildly thick is thicker than naturally thick liquids such as fruit nectars but not as thick as room-temperature honey. Pours quickly from a cup but slower than regular unmodified fluids. May leave a coating of residue in the cup after being poured. It is designed to be drunk from a cup, but effort is required to take this thickness via a standard bore straw.
Testing scales for viscosity exist but are not formalised or standardised. Subjectively, fluids at this thickness run fast through the prongs of a fork but leave a mild coating on the prongs.
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), brain injury, head and neck cancer, 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.
