About fifteen months ago, we had occasion to make a preliminary report of results obtained in the treatment for experimental ileus by the induction of splanchnic analgesia. In that communication we expressed the opinion that splanchnic analgesia was preferable to spinal analgesia, at least from the point of view of safety to the patient. From the theoretical point of view, spinal analgesia and splanchnic analgesia accomplish the same end in that they both produce a block of the splanchnic nerves. In one case (spinal analgesia) the block in the reflex pathway is made at the point of emergence of the white rami communicantes from the spinal cord, while in the other (splanchnic analgesia) the splanchnic nerves are blocked only after their complete formation as they lie in the retroperitoneal tissues anterior to the bodies of the last dorsal and first and second lumbar vertebrae.
