CONTINUOUS INTERCOASTAL NERVE BLOCK FOR PAIN RELIEF AFTER LUMBAR INCISION

To relieve postoperative pain along a lumbar incision in 9 patients the intercostal nerves were blocked with catheters for continuous epidural anesthesia. The catheters were inserted near the intercostal nerves, above and beneath the incision, just before the wound was closed and 0.25 per cent bupivacaine hydrochloride solution was infused periodically through the catheters. With this technique 5 of 9 patients had a satisfactory analgesic effect and could breathe deeply or cough without pain. The other 4 patients did not have satisfactory results and this was believed to be owing to inadequate insertion of the catheters. None of the patients had any complications. The technique is simple and can produce an analgesic effect repeatedly without causing pain for the patient.
