目的 探讨拔牙窝内填塞富血小板纤维蛋白（PRF）对双侧下颌阻生智齿拔除术后患者局部疼痛和肿胀程度的影响。方法 回顾性分析2019年10月—2022年1月于我院接受双侧下颌阻生智齿拔除术的82例患者的一般资料,按照术后有无使用PRF分为2组,每组41例。常规组41例仅给予下颌阻生智齿拔除术治疗、不使用PRF,PRF组41例在常规组基础上给予拔牙窝内填塞PRF治疗,观察2组牙周恢复情况、术后不同时间节段疼痛和肿胀情况、并发症发生率。结果 拔除前2组患者牙周袋间距（PD）和附着丧失（AL）对比差异无统计学意义（P>0.05）,随访6个月后2组PD、AL均下降且PRF组低于常规组（P<0.05）;拔除前2组患者视觉模拟评分量表（VAS）、肿胀度以及张口度均对比差异无统计学意义（P>0.05）,拔除第1、3、5、7天VAS评分、肿胀度均下降且PRF组低于常规组,张口度上升且PRF组大于常规组（P<0.05）;PRF组出血（2.44%）、感染（2.44%）以及干槽症（0.00%）的发生率略高于常规组（14.64%）、（7.32%）、（4.88%）,但组间对比差异无统计学意义（P>0.05）。结论 对双侧下颌阻生智齿拔除术后患者予以PRF填塞拔牙窝,可减轻疼痛和肿胀度,缓解张口受限,修复磨牙远中骨缺损,不影响并发症的发生率。

目的 研究麻醉恢复室(PACU)全麻患者气管内吸痰的最佳时机与按需吸痰的可行性。方法 选取2021年6月—2021年10月行经口气管插管静吸复合全身麻醉的择期手术患者240例,随机分为A组(拔管前吸痰组)、B组(入室吸痰组)、C组(入室按需吸痰组)3组,每组80例。A组苏醒时拔除导管前常规气道内及口腔吸痰;B组入PACU时提前气道内及口腔吸痰,苏醒时拔除导管,拔管后清理口腔;C组入室后参考吸痰指征评估患者气道分泌物,有吸痰指征患者吸痰,无吸痰指征者不吸痰,苏醒时拔除导管后清理口腔。分别记录患者术后入PACU时、吸痰及拔管后1 min患者的心率、血压、患者因气管刺激引起的呛咳、恶心呕吐及气道痉挛等发生例数,记录躁动评分、术后咽喉痛评分并进行评估。结果 A组与B组比较,每位患者均有吸痰,A组患者心率、血压、血氧饱和度,在吸痰后及拔管后较B组变化幅度大,差异均有统计学意义(P <0.05),气道应激反应方面,C组有20例患者按需吸痰,3组患者均未出现气道痉挛患者,A组有2例患者因拔管时剧烈呛咳引起呕吐,C组呛咳例数低于A组和B组,差异有统计学意义(P <0.05),气道刺激引起的躁动及术后咽喉疼痛C组低于A组,差异有统计学意义(P <0.05)。结论 患者在入室时按需吸痰,拔管时不再吸痰,可减少患者的心血管及气道应激反应,减少术后咽痛。

Objective To investigate the best time for endotracheal suction and the feasibility of on-demand suction in general anesthesia patients of post anesthesia care unit (PACU).Methods A total of 240 selective surgical patients who underwent oral endotracheal intubation with general anesthesia from June 2021 to October 2021 were selected.They were randomly divided into group A (sputum suction before extubation),group B (sputum suction in the room),and group C (in-room sputum suction on demand),80 cases in each group.In group A,routine airway and oral sputum suction was performed before removing the catheter when the patients were waking up.Group B had sputum sucked in the airway and mouth before entering the PACU,removed the catheter when waking up,and cleaned the oral cavity after extubation.In group C,the patients were assessed with reference of suction indications after entering the room.Sputum suction was performed for those with indications,but not for those without indications,and the mouth was cleaned after removing the catheter when awaken.Patient's heart rate,blood pressure,coughing,nausea and vomiting and airway spasm caused by tracheal irritation in 1 minute after suction and extubation were recorded after the patients entered the PACU.The tremor score and sore throat score were recorded and analyzed.Results Comparing group A with group B,each patient had sputum suction.The heart rate,blood pressure,and oxygen saturation of group A changed more significantly than group B after sputum suction and extubation (P<0.05).In terms of airway stress response,20 patients in group C needed suction,none in the three groups had airway spasm.Two patients in group A had vomiting due to severe coughing during extubation.The patients of coughing in group C were significantly less than that of group A and group B,respectively (P<0.05).The dysphoria caused by airway stimulation and postoperative throat pain in group C was significantly lower than that of group A (P<0.05).Conclusions The patient on-demand suction when enter the room,and no suction when extubation,can reduce the patient's cardiovascular and airway stress response and reduce postoperative sore throat.

目的 探讨高速改良涡轮手机拔除下颌阻生第三磨牙的临床疗效。方法 回顾性分析2013年12月—2016年12月于本科室拔除下颌阻生第三磨牙600例临床案例,按拔除方式不同,将其分为高速涡轮手机组和传统凿骨劈冠组,各300例。其中高速涡轮手机组给予高速涡轮手机拔除法拔除下颌第三磨牙,传统凿骨劈冠组给予传统凿骨劈冠拔除法拔除下颌第三磨牙。统计分析两组患者拔出后疗效情况、拔除使用时间、以及拔除后疼痛度及张口受限度情况。结果 高速涡轮手机组患者拔牙优良率明显高于传统凿骨劈冠组,差异有统计学意义(P<0.05),而疗效差发生率明显低于传统凿骨劈冠组,差异有统计学意义(P<0.05);高速涡轮手机组患者拔牙时间在30min内人数明显多于传统凿骨劈冠组,差异有统计学意义(P<0.05),而在30min以上的人数明显少于传统凿骨劈冠组,差异有统计学意义(P<0.05);高速涡轮手机组患者拔牙后疼痛度1级和张口受限度1级人数明显多于传统凿骨劈冠组,差异有统计学意义(P<0.05),而术后疼痛度2级、3级和张口受限度2级、3级均明显少于传统凿骨劈冠组,差异有统计学意义(P<0.05)。结论 高速改良涡轮手机拔除下颌阻生第三磨牙具有创口小,伤口愈合较良好,用时短以及能促进患者术后舒适。
