Cefalea secundaria a punción dural. Headache as a result of dural puncture
Abstract
Se realizó una revisión bibliográfica sobre cefalea pospunción en el Hospital "Abel Santamaría", de Pinar del Río, en el período comprendido de febrero a junio del 2004, con el objetivo de ampliar los conocimientos de los profesionales de la salud encargados de diagnosticar y tratar esta complicación. La cefalea secundaria a punción dural se debe al escape persistente de LCR (líquido cefalorraquídeo) a través del desgarro hecho en la duramadre, causado por la penetración de la aguja; se presenta cuando el paciente adopta la posición erecta y se alivia con el decúbito, característica esta que de no aparecer debe hacer dudar el diagnóstico. La elección de un trocar fino para realizar la punción y la dirección del bisel paralelo a las fibras de la duramadre son los factores determinantes en la profilaxis de la cefalea. Aún existen controversias en cuanto a su tratamiento, pero si hay un consenso unido en que el parche de sangre epidural es el tratamiento definitivo de esta complicación.

ABSTRACT
A review of the most updated literature on dural post-puncture headache was made at Abel Santamaría University Hospital in February - June 2004 aimed at spreading the awareness to health professionals at diagnosing and treating this condition. The headache secondary to dural puncture is caused by the persistent leakage of cerebrospinal fluid through the dura tear because of the needle insertion; it presents when the patient adopts the erect position and it alleviates with the supine position; if this characteristic is not present it may appear some doubts on diagnosis. The selection of a fine trocar for puncture and guiding the bevel parallel to the fibers of dura are the main factors for profilaxis of headache. Its treatment is controversial, but it does exist a consensus in that the epidural blood patch is the definitive treatment for this condition.
Key words: HEADACHE, SPINAL PUNCTURE/complications.
