Aseptic meningitis during combined continuous spinal and epidural analgesia

Continuous spinal analgesia (CSA) offers considerable advantages: (1) it requires 10% of the local anesthetic; (2) it may be instituted after patient positioning, thus minimizing the potential for cardiovascular instability; and (3) with low doses of dilute short-acting local anesthetic, the recovery period is shortened (1). Continuous spinal analgesia has been used for various procedures such as surgery and cancer pain control. However, CSA has not gained wide popularity because of its possible complications, such as headache, nerve injury, infection and accidental removal or migration of the catheter. Although real possibilities, these complications have been rarely documented. We describe an episode of aseptic meningitis during combined CSA and EA.
