Meningitis occurred in three postpartum women within three to six hours following routine low spinal anesthesia. Infectious etiologies were excluded, and in each patient a diagnosis of chemical meningitis was established after finding evidence of contamination of needles and syringes by a detergent. All three patients were clinically well within three to four days, and no neurologic abnormalities were detected following recovery. Of interest was the occurrence of hypoglycorrhachia which was particularly severe in two of the patients.
