The use of intraspinal narcotics has been widely accepted as pain relief treatment for intractable cancer pain. Intraspinal low doses of morphine induce a potent selective long lasting analgesia. To avoid repetitive lumbar puncture, a drug delivery device was surgically implanted in 41 patients. The surgical procedure is described. The mean amount of morphine needed was 1.48 +/- 0.25 mg per day at time of surgery, rising to 6.86 +/- 1.47 mg per day after a mean survival time of 65 days. Tolerance became a major problem in 18 patients, which nearly all were selected at a late disease stage and previously received narcotics for pain relief. However, no clear-cut prognostic factor had a predictive value for the appearance of tolerance. In some cases, it could be successfully treated by intraspinal injection of local anaesthetics or clonidine. CSF leakage was noted in 11 patients; this was a challenge for us, as no other authors reported such a high rate for this complication. Aseptic meningitis was noted three times. In all cases but one, the symptoms resolved with appropriate treatment.

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.

Subdural hematoma (SDH) following labor epidural analgesia is a rare neurological complication. SDH is a late complication of this procedure; it is caused by a leak of cerebrospinal fluid that may damage the vascular structures of the brain. Persistent headache in the days after labor epidural analgesia is a nonspecific clinical symptom caused by hematoma. Preexisting vascular malformations can be a concomitant cause of headache. Clinical cases have been reported even after epidural anesthesia. The differential diagnosis includes unspecified headache, sinusitis headache, drug-induced headache, cortical vein thrombosis, fistula of the dura mater, and bacterial, viral, and aseptic meningitis.
