Background:
Obstetric patients are at higher risk of postdural puncture headache (PDPH) than other age- and sex-matched individuals. The debate over the long-term effects of PDPH continues. In this study, we aimed to assess the development of new-onset headaches or worsening of pre-existing chronic headaches in patients who underwent cesarean section under spinal anesthesia and developed PDPH.
Methods:
Forty patients who developed PDPH (Group P) after cesarean section surgery (post-cesarean section-PCS), 80 patients who underwent cesarean section under spinal anesthesia (Group S), and 80 patients who underwent cesarean section under general anesthesia (Group G) were evaluated in the study. Chronic headache and other related symptoms that were present before pregnancy (pre-gestational-PG) and within 12 months after cesarean section were assessed.
Results:
Eight of the 40 patients in Group P had a new-onset chronic headache after cesarean surgery, which was significantly higher than the rates in the other groups (p = 0.001). Of the patients whose pre-existing headache worsened during the PCS period, seven were in Group P, and four were in Group S (p = 0.020), while none was in Group G. According to the multiple logistic regression analysis, the risk of worsening headache increased by 1.51-fold for every 1 unit increase in the PG Numerical Rating Scale (NRS).
Conclusion:
In conclusion, patients who develop PDPH appear to be at higher risk of developing new-onset headaches or worsening of pre-existing headaches compared with those who do not. We believe that keeping a headache diary for patients who will undergo dural puncture for whatever purpose, and also long-term follow-up of these patients for the risk of chronic headaches may increase awareness of this issue.
