[New trends in analgesic therapy: subarachnoid, peridural, and perineural perfusion of morphine using a micropump]

Attention is drawn to the suitability of employing morphine in long and medium-term antalgic management. Exceptionally good results are observed when the drug is administered very near dolorific receptors located in the peripheral and central nervous systems. An account is also given of experience gained at the Antalgic Therapy Centre, University of Trieste, in the use of morphine via several routes: peridural, perinervous, subarachnoid, per os, i.m., and i.v. A new feature of major importance in this respect is the continuous perfusion of the peridural space, nerve trunks, and subarachnoid space by means of a micropump.
