Background and objectives: There is debate regarding the use of central neural block in the presence of hemostasis-altering drugs. This study aims to examine current practice.
Methods: A survey was made of the members of the Scottish Society of Anaesthetists and the U.K. branch of the European Society of Regional Anaesthesia to determine the pattern of use of central neural block in patients who are receiving drugs known to alter hemostasis.
Results: Spinal anesthetics were considered safer than single epidural injections (P < .05) and single epidural injections safer than infusions via epidural catheters (P < .05).
Conclusions: There is general agreement regarding contraindication of central neural block in the presence of full anticoagulation with either heparin or warfarin, but there is less consensus about the use of central neural block in the presence of low-dose subcutaneous heparin. There is some confusion about the role of aspirin and its duration of action.

Multiple methods of delivery of epidural opioids are acceptable, including bolus injection, continuous infusion, and patient-controlled infusion. The incidence of side effects appears to be reduced with the use of continuous infusion techniques, especially with the liquid-soluble opioids, although these appear to be most effective when infused near the center of the dermatomal pain site. with more distant catheters, the water-soluble opioids are more effective, but there use is associated with more frequent side effects. The lowest dose requirement appears to be associated with PCEA, but further study is needed to confirm the theoretical safety and efficacy of this modality, especially if a constant background infusion is used along with the PCEA. At present, significant advantages appear to be obtainable by adding local anesthetic to the opioid infusion, but the ideal drug and dosage are yet to be determined.
