Anaesthesist. 1975 Mar;24(3):120-4.
Caudal anesthesia was achieved with Xylocain-R in 13 dogs and with ethanol (99,2 percent) in 8 dogs. Urinary bladder function was studied before and after block. The results obtained are in agreement with the functional changes after rhizotomy of S1--S3: bladder capacity increases after cuadal block and pressures measured at equal volumes decrease. Urinary overflow was observed; 80 percent of the filling volume, however, remains within the bladder. An autonomous bladder contraction induced by smypathetic nerve activity could not be proven within our observation period of 7 days.
13只犬用赛罗卡因 - R进行骶管麻醉，8只犬用乙醇（99.2%）进行骶管麻醉。在阻滞前后对膀胱功能进行了研究。所获得的结果与S1 - S3神经根切断术后的功能变化一致：骶管阻滞后膀胱容量增加，等容时测得的压力降低。观察到尿溢流；然而，80%的充盈量仍保留在膀胱内。在我们7天的观察期内，未能证实由交感神经活动诱发的自主性膀胱收缩。
