    Insights

    Polyvinylpyrrolidon-Jod-Komplex (P.J.K.) did not cause fibrosis or adhesions in rabbit epidural spaces after surgery. This microbicide shows promise for safe local lavage in spinal procedures.

    Area of Science:

    • Neurosurgery
    • Microbiology
    • Histology

    Background:

    • Epidural space infections are a risk in spinal surgery.
    • Antiseptic lavage can prevent infection but may cause tissue damage.
    • Polyvinylpyrrolidon-Jod-Komplex (P.J.K.) is a known microbicide.

    Purpose of the Study:

    • To evaluate the safety of Polyvinylpyrrolidon-Jod-Komplex (P.J.K.) for local lavage of the epidural space.
    • To assess potential adverse effects like fibrosis and adhesions.
    • To determine the efficacy of P.J.K. in preventing complications post-laminectomy.

    Main Methods:

    • Experimental study involving 20 rabbits.
    • Lumbar laminectomy followed by epidural lavage with either P.J.K. or NaCl (control).
    • Macroscopic and scanning electron microscopy (SEM) examination of meningeal coverings after one month.

    Main Results:

    • No macroscopic signs of fibrosis or arachnoid adhesions were observed in the P.J.K. group.
    • SEM analysis confirmed the absence of fibrosis and adhesions.
    • The control group (NaCl) also showed no signs of fibrosis or adhesions.

    Conclusions:

    • Local lavage of the epidural space with Polyvinylpyrrolidon-Jod-Komplex (P.J.K.) is safe.
    • P.J.K. does not induce fibrosis or arachnoid adhesions in the short term.
    • Further research is warranted to explore P.J.K. for infection prophylaxis in spinal surgery.
