Benzodiazepines are given orally as a premedication before an interventional radiological procedure. Local analgesia is achieved by drugs such as lidocaine, bupivacaine or ropivacaine. General analgesia is obtained by non opioid analgesics and opioid narcotics. ⋯ Monitoring equipments, drugs and nursing staff assistance should be provided in the interventional suite. Vital signs should be monitored for several hours until patient's discharge. Close collaboration between anesthesiologists and interventional radiologists is a prerequisite for achieving high standard sedation and analgesia.

A questionnaire was mailed to 217 interventional radiologists to evaluate current practice in analgesia and sedation in adults. Response rate was 15% (33/217). Diagnostic angiography was performed with local anesthesia in 94% to 99%; for PTA, local thrombolysis or stent placement, light sedation was added in 0.1%. ⋯ Intravenous sedation was applied given in 53% of percutaneous biliary drainage, in 42% of bile duct dilatation or stenting, in 40% of percutaneous nephrostomy and in 72% of ureteral balloon dilatation. Patient monitoring during an interventional procedure was always carried out by an anesthesiologist in 52% of cases. 21% of radiologists never visited the patient before a therapeutic procedure, and 36% never did so after completion of a procedure. This survey showed that high standard practice of sedation and analgesia, with the assistance of anesthesiologists, is underused by interventional radiologists in Belgium.
