Clinical Report: Legacy of Dr. Rick van Saene and Selective Decontamination of the Digestive Tract
Overview
Dr. Rick van Saene, a pioneering microbiologist, introduced the selective decontamination of the digestive tract (SDD), a strategy that has significantly reduced infections and mortality in critically ill patients. Despite initial controversy, SDD is now widely accepted and incorporated into international sepsis management guidelines.
Background
Infections in critically ill patients, especially those with multiple trauma, have long posed a challenge in intensive care. Traditional microbiology approaches often conflicted with new preventive strategies. Dr. Rick van Saene collaborated with intensive care specialists to develop SDD, a four-component approach aimed at controlling infections by targeting gut microorganisms. Over four decades, SDD has been extensively studied and debated, ultimately gaining global acceptance.
Data Highlights
SDD has been evaluated in at least 73 randomized controlled trials, 16 meta-analyses, and 9 theses, making it the most thoroughly researched intervention in Intensive Care Medicine. It is now included in the 2026 Surviving Sepsis Campaign international guidelines and is used worldwide in intensive care units.
Key Findings
Dr. Rick van Saene introduced the innovative SDD strategy in the early 1980s to prevent infections in critically ill patients.
SDD consists of a four-component approach targeting gut microorganisms to reduce infection risk.
Initial resistance from traditional microbiologists and infectious disease specialists led to decades of debate.
Extensive research including over 70 randomized controlled trials and multiple meta-analyses supports the efficacy and safety of SDD.
SDD is now incorporated into the 2026 Surviving Sepsis Campaign guidelines and widely implemented globally.
Dr. van Saene remained dedicated to teaching and advancing SDD despite personal health challenges.
Clinical Implications
Clinicians should consider SDD as an effective infection control strategy in intensive care settings, particularly for patients at high risk of sepsis. Its inclusion in international guidelines underscores its safety and mortality benefit. Ongoing education and adherence to the four-component protocol are essential for optimal outcomes.
Conclusion
Dr. Rick van Saene's pioneering work on SDD has transformed infection prevention in intensive care, saving countless lives worldwide. His legacy endures through the widespread adoption of SDD and continued research in critical care microbiology.
