  • 右美托咪啶复合局部麻醉在喉癌切除术前气管造口术中的应用

    目的研究右美托咪啶复合局部麻醉在喉癌切除术前气管造口术中的应用。 方法选择2009年1月-2011年12月将要施行全喉切除或喉部分切除+喉功能重建术的40例喉癌患者,随机分为局部麻醉对照组(对照组)和右美托咪啶复合局部麻醉组(研究组),每组20例。观察两组气管切开术前、术中及术后平均动脉压(MAP)、心率、血氧饱和度(SpO2),术中采用Ramsay镇静评分观察患者镇静情况,以评分在2~4分为优。 结果与对照组比较,术中研究组较患者MAP、心率稳定,组间差异有统计学意义(P<0.05);SpO2均无明显波动,组间差异无统计学意义(P>0.05),但呛咳、屏气、挣扎发生率明显降低,麻醉效果更满意(P<0.05)。 结论右美托咪啶复合局部麻醉较单纯局部麻醉能更好地满足喉癌切除术前气管造口术的要求,增加患者舒适度,且无不良反应。

  • Application of Nasopharyngeal Airway in Obesity Patients during General Anesthesia Induction

    ObjectiveTo evaluate the superiority of nasopharyngeal airway on obesity patients during general anesthesia induction period. MethodForty-two trachea cannula and general anesthesia obesity patients treated from June to November in 2013 were chosen and divided equally into two groups:nasopharyngeal airway group (group A) and control group (group B). Mean arterial pressure (MAP), heart rate (HR), pulse oxygen saturation (SpO2), arterial blood partial pressure of carbon dioxide (PaCO2) were recorded when the patients entered the operation room, three minutes after man-made positive pressure ventilating and five minutes after intubation. Peak voltage (Ppeak) of man-made positive pressure ventilation for three minutes was also observed, and intubation frequency and time, mouth mucosa bleeding, and sore throat examples were compared between the two groups. ResultsCompared with group B, MAP, HR, PaCO2 and Ppeak three minutes after man-made positive pressure ventilating were lower (P<0.05), but SpO2 was higher in group A (P<0.05). Intubation frequency and time, mouth mucosa bleeding, and sore throat examples of group A were less than those in group B (P<0.05). ConclusionsNasopharyngeal airway is better for obesity patients during general anesthesia induction period, which also improves anesthesia safety level.
