The haemodynamic response to the insertion of the laryngeal mask airway: a comparison with laryngoscopy and tracheal intubation

The haemodynamic response to the insertion of the laryngeal mask airway (LMA) was assessed and compared to that of laryngoscopy and tracheal intubation in a study of forty patients (ASA 1) randomly allocated into two groups and anaesthetised using a standard balanced anaesthetic technique. The results show that the changes in all cardiovascular parameters measured following LMA insertion were significantly less (P<0.05) when compared with those following laryngoscopy and tracheal intubation. We conclude that airway management with the LMA may be used to avoid the haemodynamic response to tracheal intubation where such a response is undersirable.

郃郎喘必消冲剂的药理研究

本文通过对小鼠急性毒性实验,抗炎实验,对胸腺脾脏的影响及对豚鼠在体、离体气管平滑肌作用实验,观察了郃郎喘必消冲剂的药理学效应。结果表明,该制剂无明显毒性,最大耐受量为1000g/kg/d。它有明显的对抗二甲苯致小鼠耳炎及延长组胺诱发哮喘发作潜伏期的作用,对豚鼠离体气管平滑肌无松驰作用,对小鼠胸腺和脾脏有使其重量减小的趋势,但与对照组比较无显著性差异。     

Congenital tracheal stenosis in Pfeiffer syndrome

We report an infant with Pfeiffer syndrome (acrocephalosyndactyly type V) and a solid cartilaginous trachea lacking rings. This airway abnormality has been reported in a child with Crouzon syndrome but has not been described in Pfeiffer syndrome.     

引导管芯在更换经口气管导管的应用

目的 观察应用引导管芯做引导，更换经口气管内导管的临床效果。方法 随机选择26例已完成气管内插管的病人，将引导管芯插入气管导管内至隆突水平，并拔出气管导管；将欲更换的气管导管套在引导管芯外，在管芯引导下将气管导管插入气管内，完成换置；结果 全部病例均顺利完成更换导管，换管过程中病人氧合良好，术后未发生与更换导管相关并发症；结论 应用引导管芯更换气管内导管，方法安全，简便易行，可替代传统换管方法。
