N_2O吸入镇静辅助椅位视频在牙种植术中的应用

N_2O inhalation sedation accompanied by the chair video in dental implants

目的观察种植牙患者在N2O(俗称笑气)吸入镇静辅助椅位视频配合局部麻醉状态下行种植牙手术的效果。方法选取60例种植牙手术的患者随机分成实验组和对照组,每组30例。手术包括种植体同期植入术、上颌窦提升术、onlay植骨术。实验组用N2O吸入镇静辅助椅位视频配合局部麻醉进行手术,对照组单纯采用局部麻醉进行手术。通过观察心率、血压等变化,对2组患者手术疼痛耐受程度差异和手术过程中镇静程度差异进行评定。结果对照组患者手术前和手术中的心率、血压明显高于实验组;且与对照组相比较,实验组术前、术中的镇痛镇静效果以及手术耐受和配合程度明显提高。结论N2O吸入镇静辅助椅位视频配合局部麻醉安全、有效,值得在牙种植术中推广。

Objective To observe the effect of inhaling N2O （called laughing gas） superficial anesthesia accompa- nied by the chair video in combination with local anesthesia in patients undertaking dental implantation. Methods 60 patients undertaking dental implantation were selected and divided randomly into two groups （30 in each）. The operations include bilateral maxillary sinus lift operation, onlay bone graft operation and operation of simultaneous placement of multiple implants. Adopt superficial anesthesia by inhaling N2O accompanied by the chair video in combination with local anesthesia for the experiment group and adopt local anesthesia for the control group. Changes in the heart rate and blood pressure were observed to evaluate differences in level of the pain tolerance and the sedation in two groups. Results The heart rate and blood pressure of control group were significantly higher than the patients in the experiment group. The level of sedation and the degree of pain tolerance in the control group were significantly lower than the patients in the experiment group. Conclusion Inhaling N20 super- ficial anesthesia accompanied by the chair video in combination with local anesthesia is safe and effective, which should be widely applied in dental implant.
