Overall practice was in accordance with national guidelines or practice patterns defined by the expert committee. Regional anaesthesia and postoperative analgesia-related techniques particularly were adequate. Some deficits were of limited importance (antibiotic prophylaxis and oxytocin administration), whereas others (use of succinylcholine and cricoid pressure) remain of concern.

The results of this study showed that the incidence of spinal anesthesia failure was 3.2%. The number of puncture attempts at 3 or more and the absence of adjuvant medication associated with local anesthetic were independent factors associated with the increased risk of failure. The failure of spinal anesthesia was rare in patients older than 70 years.

We conclude that only 30 mL of local anaesthetic seems to be sufficient to ensure a high level of success when performing an infraclavicular block with stimulation of both the musculocutaneous nerve and median, ulnar or radial nerve.
