[Postspinal headache--incidence and prognosis].

Spinal anaesthesia was performed in 776 adult patients with 22 G and 25 G spinal needle. The incidence of postdural puncture headache was 3.5%. Its association to age, sex, needle size, duration of postoperative recumbency was analyzed. Our results show that the age was a significant predictor of postlumbar puncture headache. Postspinal headache was more often found in younger patients (p < 0.001).
