CIRSE Standards of Practice on Analgesia and Sedation for Interventional Radiology in Adults


This CIRSE Standards of Practice document provides best practices for the safe administration of procedural sedation and analgesia for interventional radiology procedures in adults. The document is aimed at health professionals involved in the provision of sedation and analgesia during interventional radiology procedures. The document has been developed by a writing group consisting of physicians with internationally recognised expertise in interventional radiology, and analgesia and sedation.

Appendix: ASA recommendations for fasting before sedation, anaesthesia and procedures

Appendix: ASA recommendations for fasting before sedation, anaesthesia and procedures

  • Clear liquids may be ingested for up to 2 h before procedures requiring general anaesthesia, regional anaesthesia, or procedural sedation and analgesia.

  • A light meal or non-human milk may be ingested for up to 6 h before elective procedures requiring general anaesthesia, regional anaesthesia, or procedural sedation and analgesia.

  • Additional fasting time (e.g. 8 or more hours) may be needed in cases of patient intake of fried food, fatty food or meat.

  • Both the amount and type of food ingested must be taken into account when determining an appropriate fasting period.

  • Since non-human milk is similar to solids in gastric emptying time, consider the amount ingested when determining an appropriate fasting period.

  • In the case of urgent or emergent situations where gastric emptying is not possible, do not delay moderate procedural sedation procedure based on fasting time alone; this condition may require an anaesthetic involvement/referral.

  • Refer to the specific guideline for additional details [10].
