摘要:: [摘要]目的：分析下牙槽神经阻滞对下颌骨骨折患者镇静程度及咬合不佳的影响。方法：选择2017年1月-2019年12月笔者
医院收治的122例下颌骨骨折患者，采用随机数字表法分为对照组和观察组，每组61例。对照组采用常规全身麻醉，观察组
在对照组麻醉的基础上采用下牙槽神经阻滞进行麻醉。比较两组一般资料和手术情况、两组拔管时和拔管后10min两组疼痛
视觉模拟评分（VAS）和Ramsay镇静评分，比较两组术前、术后拔管时、拔管后10min平均动脉压（MAP）、心率（HR）和术
后两组不良反应发生情况；术后随访1个月，比较两组手术前后咬合功能。结果：术后，观察组拔管时间显著短于对照组
（P ＜0.05）。拔管后10min与拔管时比较，两组VAS评分升高，观察组低于对照组，麻醉失效时与拔管后10min和拔管时比
较，两组VAS评分均降低，观察组低于对照组；拔管时、拔管后10min和麻醉失效时两组Ramsay评分均呈逐渐降低趋势（P
＜0.05），组间比较差异无统计学意义（P ＞0.05）。拔管时、拔管后10min观察组MAP、HR低于手术前，并低于对照组（P
＜0.05）；拔管后10min，对照组MAP、HR高于拔管时（P ＜0.05）。术后1个月，两组最大咬合接触面积、最大咬合力较治疗
前均增大，观察组大于对照组；两组咬合力不对称指数较术前显著降低，观察组低于对照组（P ＜0.05）。术后，两组不良

者进行麻醉能通过增强患者局部镇痛作用而有效减轻患者术后疼痛，降低术后患者MAP和HR，有助于患者咬合功能的恢复，

Abstract:: Abstract: Objective To analyze the effect of inferior alveolar nerve block on the sedation degree and poor occlusion in patients
with mandibular fracture. Methods A total of 122 patients with mandibular fractures admitted to our hospital from January
2017 to December 2019 were selected and randomly divided into control group and observation group with 61 cases each. The
control group was anesthetized with conventional general anesthesia, and the observation group was anesthetized with inferior
alveolar nerve block. The two groups were compared for general information and surgical conditions. Visual analogue pain
scores (VAS) and Ramsay sedation scores were compared between the two groups at extubation and 10 min after extubation.
Mean arterial pressure (MAP), heart rate (HR) and adverse reactions were compared between the two groups before surgery,
during extubation, and 10 min after extubation. Postoperative follow-up was conducted for 1 month to compare the occlusal
function of the two groups before and after surgery. Results After operation, the extubation time in the observation group was
significantly shorter than that in the control group (P ＜0.05). VAS scores of the two groups increased at 10 min after extubation
compared with that at extubation, and VAS scores of the observation group were lower than that of the control group. Ramsay
scores of the two groups showed a gradually decreasing trend at the time of extubation, 10 min after cupping and anesthesia
failure (P ＜0.05), and there was no statistically significant difference between the two groups (P ＞0.05). During extubation, 10
min after extubation, MAP and HR in the observation group were lower than those before surgery and lower than those in the
control group (P <0.05). 10 min after extubation, MAP and HR in the control group were higher than that at extubation (P ＜0.05).
One month after the operation, the maximum occlusal contact area and the maximum bite force of the two groups increased
compared with that before treatment, and the observation group was larger than the control group (P ＞0.05). The number of
