[Incidence of post-dural puncture headache using the 24G "pencil tip" needle. Prospective study in 100 young patients]. / Incidencia de cefalea pospunción dural con la utilización de la aguja "punta de lápiz" 24G. Estudio prospectivo en 100 pacientes jóvenes.

We studied the incidence of headache after dural punction using a "pencil-tip" 24G needle in 100 patients aged 15 to 55 years (mean 31.4 years) undergoing surgical interventions that allowed early physical activity. The study variables were age, sex, anesthetic agent, and previous history of headache. All patients received 1,500 ml of Ringer lactate during the peroperative period and after 48 hours the presence of headache was investigated. Headache was not observed in any case. We conclude that the pencil-tip 24G needle has been effective in the prevention of headache after dural punction particularly in young patients, who are traditionally considered to be at risk.
