A retrospective audit of obstetric epidurals was performed at Royal Surrey County Hospital. The aim was to determine the efficacy of epidural blood patch in the management of post-dural puncture headache following inadvertent dural puncture in the obstetric population, over a 5-year period between March 1993 and February 1998. During that time, there were 55 recognized dural punctures (overall incidence 0.96%). A total of 62 epidural blood patches were performed in 48 patients. Following treatment with one epidural blood patch, 33% of patients obtained complete and permanent relief, 50% partial relief and 12% no relief. Twenty-nine percent of patients required a second epidural blood patch of which 50% were completely successful, 36% were partially successful and 14% gave no relief.
