Cosyntropin has been suggested to decrease the incidence of post-dural puncture headache (PDPH) by increasing the production of cerebrospinal fluid. This study examined the association of prophylactic cosyntropin administration with the incidence of PDPH and its management with an epidural blood patch after an unintentional dural puncture (UDP).
We conducted a retrospective cohort study of cases with UDP during placement of neuraxial labor analgesia. Per institutional practice and at the discretion of the anesthesiologist, intravenous cosyntropin 1 mg may be administered for PDPH prophylaxis. PDPH, time from UDP to cosyntropin administration, time to development of PDPH, and management with epidural blood patch(es) were recorded.
Cosyntropin was administered in 164 of 234 (70%) cases with UDP. PDPH occurred 98/164 (60%) with cosyntropin and 45/70 (64%) without cosyntropin (p = 0.66). The PDPH adjusted incidence was 53% with cosyntropin and 62% without cosyntropin, difference 9% (95% CI −6% to 24%, p = 0.25). The adjusted epidural blood patch rate was 66% with cosyntropin and 78% without cosyntropin, difference of 12% (95% CI −5% to 28%, p = 0.17).
Prophylactic cosyntropin following UDP was not associated with a significant decrease in PDPH rate or use of epidural blood patch for management of PDPH. There was no significant difference in the rate of adverse hyperglycemic or hypertensive events amongst those who did or did not receive cosyntropin.
