General

The most frequently reported side effects are acute adverse experiences which demand immediate countermeasures are related to the central nervous system and the cardiovascular system. A major cause of adverse reactions is excessive plasma levels, which may be due to overdose, unintentional intravascular injection, or slow metabolic degradation. It is also difficult to distinguish adverse reactions caused by the drug per se from the physiological effects of the nerve block (e.g. decrease in blood pressure, bradycardia, temporary urinary retention), events caused directly (e.g. spinal hematoma) or indirectly (e.g. meningitis, epidural abscess) by needle puncture or events associated to cerebrospinal leakage (e.g. postdural puncture headache).^[Ref]
