甲状腺瘤切除术在颈丛阻滞下进行,术中大多数病人血压有不同程度的增高,部分病人伴心率增快。为探讨其原因,现将近年来麻醉中收缩压升高明显[超过原水平4.0kPa(30mmHg)]及术中测定血浆T_8、T_4和皮质醇的69例,总结分析如下。资科与方法一般资料:男20例,女49例,30岁以下10例,31～40岁12例,41～50岁28例,51岁以上19例。其中术前有高血压者19例。麻醉方法:术前用阿托品0.5mg,吗啡8mg,苯巴比妥0.1g58例。东茛菪碱0.3mg,苯巴比妥0.1g 11例。采用一针法颈丛阻滞用0.25％布吡卡因45例,0.2％地卡因24例。每侧为14ml。为对比观察8例仅以浅
The resection of thyroid tumors was performed under the cervical plexus block. The blood pressure in most patients increased to varying degrees during the operation, and some patients had increased heart rate. In order to investigate its causes, the systolic blood pressure in anesthesia has increased significantly in recent years [more than the original level of 4.0 kPa (30 mmHg)] and intraoperatively determined plasma T_8, T_4 and cortisol in 69 cases, summarized and analyzed as follows. General Information and Methods General information: 20 males and 49 females, 10 patients under 30 years old, 12 patients 31 to 40 years old, 28 patients 41 to 50 years old, and 19 patients over 51 years old. Among them, 19 patients had high blood pressure before surgery. Anesthesia: Preoperative atropine 0.5 mg, morphine 8 mg, and phenobarbital 0.1 g in 58 patients. Scopolamine 0.3 mg, phenobarbital 0.1 g 11 cases. One needle method used 45 cases of 0.24% bupivacaine for cervical plexus block and 0.2% of tetracaine for 24 cases. 14ml per side. For comparison, 8 cases were only shallow
