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 探讨健康成人颈段气管的体外高频超声影像特点,为开展体外超声在检测颈段气管病变应用作前期研究。方法 应用体外高频超声观察120例健康成人颈段气管结构的声像表现,并对气管环T1-T4的内外横径、气管环厚度、相邻气管环间距进行测量和统计学分析。结果 120例志愿者均获得了颈段气管前、侧壁声像图,以及气管环T1-T4内外横径、气管环厚度、相邻气管环间距测值。结论 体外高频超声可以清晰显示气管形态和细微支撑结构,并进行部分径线测量,有望成为评估颈段气管病变的一种有价值的辅助手段。

Objective We investigated features of the healthy adult cervical tracheas in order to studying cervical tracheal lesions by extracorporeal high-frequency ultrasound EHFUS. Methods EHFUS examination of the trachea was performed in 120 asymptomatic adult volunteers. We observed imaging features of the healthy adult cervical tracheas, and measured TRID, TRED, TRTh and TRAS to analysis. Results The cervical tracheal anterior and side wall ultrasonograms, and measurements were obtained in all subjects. Conclusion The cervical tracheal shape and the fine structure of support can be seen in EHFUS, and partly of diameter measurements were obtained. Thus EHFUS may be a valuable assistant method to assess cervical tracheal lesions of support structure.

目的 探讨光棒引导与传统喉镜气管插管在不稳定型颈椎骨折患者中的应用效果。方法 不稳定型颈椎骨折患者80例,按照随机数字表法随机分成光棒引导组和传统喉镜组各40例,记录两组患者的插管时间、插管总成功率,入室安静后(T0)、诱导后插管前(T1)、气管插管后即刻(T2)、气管插管后3 min(T3)时的收缩压(SBP)、舒张压(DBP)、心率(HR)、血浆去甲肾上腺素(NE)、肾上腺素(E) 和血管紧张素Ⅱ(ATⅡ)的变化和插管时气道并发症。结果 两组间插管时间(光棒组29.63±11.04s vs.喉镜组62.41±19.49 s)有统计学意义(P<0.001)。两组插管总成功率无统计学意义(P=0.305)。光棒组T2、T3时刻SBP、DBP、HR 、NE、E和ATⅡ均低于喉镜组(P<0.001)。光棒组气道并发症低于喉镜组无统计学意义(P>0.05)。结论 光棒引导气管插管较传统喉镜气管内插管插管时间短,对血流动力学和应激激素水平影响较轻。
