Prophylaxis of neurosurgical infections by improved preoperative disinfection of the scalp.

The heads of neurosurgical patients were subject to 2 scrubbings with hexachlorophene detergent, performed in the ward prior to operation. After this single change of routines the frequency of wound infections after craniotomy dropped 4-fold, from 2% to 0.5%. The result indicates that the scalp of the patient is the major source of the staphylococci that cause neurosurgical infections.
