In minimal invasive pain therapy interventional radiologists have 4 CT-guided procedures available which generally are easy to perform and have a low complication rate. While neurolytic blockade of the celiac plexus is an established procedure, particularly in patients with malignancies in the upper abdomen, further studies are needed to establish the value of intraarticular facet blockade and CT-guided periradicular therapy. CT-guided nerve root ablation can be recommended in patients with therapy-resistant pain due to tumor compression of nerve roots.
OBJECTIVE: The aim of this study was to assess the incidence and severity of postoperative pain in patients undergoing operations in various surgery clinics in the Assistance Publique des Hôpitaux de Paris (AP-HP) and to evaluate management of pain during the 24 hours following surgery. METHODS: Data from surgical and anesthesia observation sheets and from patient complaints collected in a one-day external audit were obtained for 96 surgery clinics in the AP-HP. RESULTS: At the time of surgery, most patients were receiving opioids, especially fentanyl: low dose ( < 1 microgram/kg/h) was given in 17.1% of the patients and regional anesthesia was used in 13%. In 95% of the cases, postoperative orders were written by anesthesiologists. Initial orders were modified according to patient response in 11.8% of the cases. "On demand" prescriptions were used in 10% of the orders. Patient controlled analgesia and regional analgesia were not routine techniques (2 and 0% respectively). Finally, 37.8% of the patients were given a single prescription of a step-1 drug (e.g. propacetamol i.v.), 25.9% a step-2 drug either alone or in combination with a step-1 drug, and 28.9% of the patients were given strong opioids at least once. CONCLUSIONS: For all types of drugs, dosage level was considered as correct in 86.5% of the cases. For approximately 10% of the opioid prescriptions, an ineffective dose was used. The interval between doses was too long in 54.1% of the prescriptions for at least one drug (e.g. for peripheral analgesia with propacetamol). The incidence of severe pain was 46.4%, especially after abdominal, high urologic and back surgery.
