阴部神经阻滞麻醉,目前临床常采用坐骨棘内下方或经阴部管内阻滞注射,有其利弊之处。现据解剖学的实际,我们认为有可能在坐骨小孔处进行阴部神经的阻滞麻醉。我们在72侧成人标本上(男60侧,女12侧)观察了阴部神经和阴部内血管的排列关系。其中由内至外顺序为神经、动脉、静脉者占79.2±4.8%,为神经、静脉、动脉者占11.1±3.7%,为静脉、动脉、神经者占9.7±3.5%。故总的 Pudendal nerve block anesthesia, the current clinical use of the lower part of the ischial spondylitis or intra-genital tract block injection, has its advantages and disadvantages. According to the actual anatomy, we think it is possible in the islet hole at the block of the nerve of the genitals anesthesia. We 72 adult specimens (male 60, female 12 side) observed the relationship between the genitals and perineal blood vessels. Among them, the order of nerves, arteries and veins from internal to external was 79.2 ± 4.8%, which accounted for 11.1 ± 3.7% for nerves, veins and arteries, and 9.7 ± 3.5% for veins, arteries and nerves. Therefore, the total
