摘要
颈丛阻滞下进行甲状腺手术201例于双侧C_4注入0.25％丁吡卡因,成人总量24ml。阻滞后SBP增高≥2.7kPa 85例,占42.2％,其中阻滞前血压正常,阻滞后血压≥21.3/12kPa 38例占18.9％。术前血压>21.3/12kPa的10例中有4例血压上升25.3—28/13.3 kPa。这种血压增高的原因,可能与颈丛阻滞时、局麻药渗入颈动脉鞘阻滞迷走神经而导致交感神经兴奋等因素有关。
Changes of blood pressure in 201 cases of thyroidectomy under cervical plexus block has been studied. Bilateral injection technique of fourth cervical (C_4) with 24ml of 0.25％ Bupivacaine in adult was used. The results showed that the SBP elevated 2.7kPain 85 of 201 cases (42.2％). Normal blood pressure raised to 21.3/12 kPa after block in 38 of 85 cases (18.9％). 4 of 10 ceses whose preoperative blood pressure higher than 21.3/12kPa raised to 25.3—28/13.3kPa. The causes of hypertension may be due to local anesthetic infiltrates into the sheath of carotid artery, depresses vagus nerve and stimulates the functionof sympathetic nerve.
