Clinical Scorecard: Transparent Fluids and Enhanced Safety in Procedures: Insights from the OCULUS Study

At a Glance

CategoryDetail
ConditionPeriprocedural management of GLP-1/GIP receptor agonists
Key MechanismsReal-time gastric visualization and predefined decision pathways
Target PopulationPatients undergoing upper endoscopy while on GLP-1/GIP RAs
Care SettingProcedural settings with moderate sedation or monitored anesthesia care

Key Highlights

  • First randomized clinical trial examining GLP-1/GIP RA management before upper endoscopy
  • No clinically significant residual gastric volume observed with clear liquid diet
  • Direct gastric visualization may improve procedural safety
  • Clear liquid diet is a low-risk measure with broad applicability
  • Caution advised in interpreting subgroup analyses due to early trial termination

Guideline-Based Recommendations

Diagnosis

    Management

    • Consider continuation of GLP-1/GIP RAs after risk stratification
    • Implement clear liquid diet 24 hours prior to procedures

    Monitoring & Follow-up

      Risks

      • Potential for periprocedural aspiration risk not fully mitigated by medication withholding

      Patient & Prescribing Data

      Patients receiving GLP-1/GIP RAs undergoing upper endoscopy

      Clear liquid diet may influence gastric contents independently of medication management

      Clinical Best Practices

      • Utilize real-time gastric visualization during procedures
      • Adopt clear liquid diet protocols for patients on GLP-1/GIP RAs
