Selective Digestive Decontamination
Selective digestive decontamination (SDD) is a protocol-based treatment that aims to eradicate potentially pathogenic gut flora, particularly aerobic gram-negatives, in critically ill patients to reduce the impact of aspiration events. The utilization of SDD and the available literature center firmly on critically ill and ventilated patients. Subsequent studies have demonstrated recolonization after protocol cessation, and long-term effects are currently undefined.5 Until it can be studied in broader populations and proven to have clinical benefit, employing SSD in non-critically ill patients with dysphagia remains unsupported.
Multimodal Approach
Many rehabilitation centers incorporate a therapist-driven swallowing treatment program. Evidence suggests patient and family counseling alone may not be effective, so these programs variably incorporate diet/liquid modification, strengthening exercises, sensory processing techniques, and even neuromuscular electrical stimulation for muscle building.1 Accordingly, these programs are resource-intensive.
Management
Dysphagia remains a significant clinical problem for hospitalized patients. The existing literature and practice guidelines generally support a “less is more” approach. Though liquid/diet modification is common practice, it is not based in solid evidence and may contribute to unnecessary tube feeding. The best current evidence supports allowing access to water and ice chips. The ideal management plan for each patient will differ and should incorporate patient and family preferences in a multidisciplinary approach.
Back to the Case
Our patient requests water. He coughs after drinking during a bedside swallow evaluation. The risks of potential aspiration and AP are explained, and he expresses his understanding. He reiterates his choice to be allowed access to water as it is important to his quality of life. The speech therapy team is consulted and provides instruction on chin-tuck positioning, oral care, and timing water between meals rather than while eating food. He does well for the remainder of the hospital stay, and by time of discharge, his electrolytes are corrected, and he is much more comfortable being allowed to drink water. He is discharged home and encouraged to continue with these conservative measures.
Bottom Line
Evidence to support many common interventions for dysphagia is lacking; patients with dysphagia are best managed via a multidisciplinary, multimodal approach that provides access to water whenever possible. TH
