[Changes in the spinal fluid pressure due to spinal anaesthesia in the sheep (author's transl)].
In five adult horned sheep long-term cerebro-spinal fluid pressure measurements were carried out before, during and after ten spinal-anaesthetics with the help of a canula which was fixed on the skull. In the lumbar subarachnoid space the pressure-course was recorded also, before and after the injection of local-anaesthetic. The following reproducible phenomena were found: Rapid pressure increase after injection, increase of cardio-respiratory oscillations and in two cases a sharp decrease of pressure after removal of the spinal needle. A connection between this and the cause of postural headache in man is postulated.
