Regional blocks require little or no home care. But the procedure itself may require monitoring and treatment. The procedure usually causes more problems during recovery at home than the medication.
Regional blocks are unlikely to cause complications. Allergic reactions are possible and may cause temporary breathing problems. In rare cases, if the medication is accidentally injected into the bloodstream, or if too much is used, seizures or arrhythmias may occur.
The American Society of Anesthesiologists recently issued a warning about the potential side effects and interactions of herbal remedies with medications used before, during, and after surgery. The group recommends discontinuing the use of all herbal remedies and supplements at least 2 weeks before planned surgery.
