无痛麻醉仪配合护理干预在下颌埋伏阻生智齿拔除中的应用效果

目的探讨无痛麻醉仪配合护理干预对下颌阻生智齿拔除术中麻醉注射时患者血压、脉搏、心率变化的影响。方法将120例下颌阻生智齿拔除术患者随机分成两组各60例，实验组采用无痛麻醉仪牙周膜投递麻醉药物，对照组采用传统下齿槽阻滞麻醉投递麻醉药物，两组均给予常规护理，实验组在此基础上又给予相应护理干预，分别在麻醉前和麻醉中不同时间点监测患者的血压、脉搏、心率以及注射麻药过程中的疼痛值评分。结果实验组患者麻醉注射时VAS疼痛评分为（1．582±1．025）分，低于对照组评分（4．935±7．513）分，差异有统计学意义（t=-3．127，P〈0．01）；实验组在麻醉药物投递前后患者的血压、心率变化差异均无统计学意义（P〉0．05）；对照组的收缩压在麻醉前、中、后2min、手术后的数值分别为（116．18±10．83），（130．36±10．15），（131．66±8．90），（116．94±10．29）mmHg，各时间段比较差异均有统计学意义（F=126．735，P〈0．01），舒张压在各时间段比较差异有统计学意义（P〈0．01），心率各时间段差异无统计学意义（P〉0．05）；两组患者麻醉注射不同时间点血压及心率变化差值的比较差异均有统计学意义（19〈0．05）。结论无痛麻醉仪给予麻醉药物配合有效的护理干预能显著减小患者的疼痛感，最大限度减小患者的血压和心率变化，降低麻醉时的并发症。

Effect of painless anesthesia instrument coordinated with nursing intervention during single tooth anesthesia for mandibular impacted tooth extraction

Objective To investigate the effect of nursing intervention coordinated with painless anesthesia instrument during single tooth anesthesia for mandibular impacted tooth extraction.Methods 120 patients of mandibular impacted tooth extraction were randomly divided into two groups:the experimental group (60 cases) was given anesthetic by the WAND single tooth anesthesia while the control group (60 cases) was given conventional inferior alveolar nerve block anesthesia.Both groups received routine nursing,while the experimental group was given additional nursing intervention.Blood pressure (BP),pulse and heart rate (HR) of the patients were measured at various time intervals.The value of visual analogue scale (VAS) was also recorded and evaluated.Results The VAS score of the experimental group ( 1.582 ± 1.025 ) was significantly lower than that of the control group (4.935 ±7.513) and the difference was statistically significant.There was no significant difference of BP and HR of the experimental group before and after the anesthesia.Systolic pressure of the control group during the three stages of anesthesia and pest-operation was ( 116.18 ± 10.83),( 130.36 ± 10.15 ),( 131.66 ± 8.90),( 116.94 ± 10.29) mmHg,respectively.There was significant difference among the four intervals (F =126.735,P ＜ 0.01 ),DBP among the four intervals was statistically significant( P ＜0.01 ),HR was no difference( P ＞0.05).Significant differences were found of the changes of BP and HR at various timing of anesthesia between the two groups ( P ＜ 0.05 ).Conclusions The WAND single tooth anesthesia and effective nursing intervention produced a significantly lower pain score and safer anesthesia range than conventional inferior alveolar nerve block anesthesia.
