[Analysis of infectious sequelae of 1000 neurosurgical operations. Effects of prophylactic antibiotherapy].
Postoperative infections: cellulitis at the site of skin incision and/or meningitis, were reported in 5.1 p. cent of 1 000 cases treated by neurosurgery in Pr R. Houdart's department between december 1980 and march 1982. Statistically significant factors predisposing to infection were: emergency surgery, opening of the sinus, presence of a foreign body, and operation lasting more than 5 hours. The age of the patient, diabetes, or previous corticoid therapy did not significantly alter the risk of infection. Prophylactic antibiotic therapy had been administered to 37 p. cent of patients, but this had not affected the incidence of general infection, a statistically significant effect being observed only after operations lasting for more than 5 hours. The risk of infection was high after craniotomies and major after external ventricular shunts (valves). For the latter type of operation it was not possible to determine factors favorable for infection: neither duration of surgery, nor age of patient, nor absence of antibiotic therapy. The risk of postoperative infection was low (less than 1 p. cent) in the absence of factors favorable for its development, but its frequency increased considerably in patients presenting one or more other intercurrent infections. It is therefore possible to recognize surgical and general factors influencing infection, but prophylactic antibiotic therapy has only a weak effect on morbidity modification.
