The technique of combined spinal epidural anaesthesia (CSE) combines the versatility of spinal with the variability of epidural anaesthesia. Spinal application of the local anaesthetic achieves a fast response, reliable sensorial and motor block at a low dose with little toxicity. The epidural catheter allows for the duration of surgical anaesthesia to be extended and provides analgesia for the postoperative period. ⋯ CONCLUSION. Owing to the possibility of medico-legal consequences, which sometimes occur a long time after anaesthesia has been given, we think it is unwise to reuse such needles. We hope that disposable and cheap 29 gauge needles will soon become available.

After remission of the dermatological symptoms of herpes zoster infection, post-zoster neuralgia (PZN) can persist or recur for months and years. Most frequently, satisfactory therapy of PZN is not possible. During recent years the persistence of viruses on the surface of neuronal cells has been discussed as the possible reason for chronic pain. ⋯ Treating pain in persistent PZN is extremely difficult and mostly results in a small diminution of the pain level. Persistence of viruses on the neuronal cell surface and resulting reduction of "luxury functions" of those cells may explain algogenesis by PZN and resistance to therapeutic efforts. We used VZI for the first time for therapy of PZN and observed a striking analgesic effect in all patients for the entire surveillance time.
