(2)The clinical research of the long-term implantation epidural catheter of report such as Dupen, 350 examples are the adult patient of malignant tumor or AIDS pain, placed epidural catheter 457 days, wherein subcutaneous cellulitis takes place in 30 examples, 8 routine deep soft tissues infect, and 15 routine epidural spacies infect, and most of infection betides puts pipe about 190 days, all take the control of antibiotic postoperative infection, no death
(3)Domestic correlational study thinks, puts pipe injection analgesic through epidural-hypodermic tunnel and treats cancer pain, and analgesic effect is good, and dosage is little, to respiratory center, that smooth muscle suppresses degree is low, and adopts the tunnel to put pipe, can reduce the chance that epidural space infects
(4)
To sum up analyze, epidural-subcutaneous embedded this new technique of pipe analgesia art of putting has major application to be worth aspect pain therapy, and the pertinent literature report has been proved feasibility, safety and the superiority of this technology clinical practice.But look back from epidural-subcutaneous embedded research of putting pipe analgesia art, Chinese scholars research only is confined to epidural-subcutaneous embedded clinical practice of putting pipe analgesia art, lacks the research to this new technique perfect performance of analgesia pump system, technological improvement.Above-mentioned Dupen touches upon, and long-term embedding epidural catheter can cause the infection at epidural and other positions.
