Post-dural-puncture headache (PDPH) is a potential complication of neuraxial anesthesia techniques.
The incidence of developing PDPH following accidental dural puncture is affected by several patient variables:
- Age - those < 40 years old are more susceptible
- Gender - females are more susceptible than males
- Weight - morbid obesity appears to decrease the incidence
- Pregnancy - increases incidence
- Prior history (of PDPH) - increases incidence
Additionally, incidence decreases with higher needle gauge, increased provider experience, and use of saline (rather than air) for loss of resistance during neuraxial anesthesia techniques.
