Children''s development effecting blood oxygen desaturation following apnea.

One hundred and fifty-six children aged from 4 months to 12 years undergoing elective plastic surgery were included in this study. All children were ASA physical status I, under normal development, ranging from 64 to 140 cm in body height and from 6.0 to 41.0 kg in body weight. Following 2-minute preoxygenation, the time when SpO2 dropped to 95% and 90% in apneic period had a close correlation with age, weight and height of children by means of linear and non-linear-regression analysis. The smaller the children's weight, the higher the incidence of severe arterial desaturation after reinstitution of manual ventilation with 100% oxygen at SpO2 of 90%. It is suggested that younger children are more susceptible to hypoxemia than older ones during apnea and provided no problem existing other than oxygen delivery, an SpO2 of 95% might be the safe limitation of apnea in pediatric anesthesia induction.     

异氟醚用于控制性降压的研究近况

虽然目前临床用于控制性降压(简称降压)的药物有多种,但仍无一种药物令人满意,探索起效快,恢复迅速,可控性强,安全范围大和对机体生理干扰小的降压药物一直是麻醉学界瞩目的课题。异氟醚是近年来用于临床的新型吸入麻醉药物,与同类吸入麻醉药物相比,异氟醚除具有麻醉效能强,体内蓄积量少,毒性低和安全范围宽等优点外,异氟醚还具有独特的心血管效应,随着异氟醚吸入浓度增加,外周血管阻力和动脉     

新生儿窒息复苏的体会

我院自1982年8月～1985年6月共抢救新生儿窒息48例,其中42例应用气管内插管-吸引-正压人工呼吸,成功46例,小结如下:临床资料一、本组均为出生后20分钟内的新生儿,男30例,女18例。其中青紫窒息24例.苍白窒息24例。阴道分娩20例,剖腹产28例。新生儿娩出后心跳停止5例,心率<80次/分6例,心率<40次/分4例。按Apgar评分法,0分5例,1分9例,2～3分25例,4～5分7例,6～7分2例。二、窒息原因:窒息往往是多种复合原因所致。

罗库溴铵的药理学研究及临床应用

罗库溴铵是新合成的中效甾族非去极化肌松药,其肌松维持时间和恢复时间与维库溴铵相似,但是起效较快,更适合于快速诱导气管内插管,且水溶液性质稳定,无明显心血管反应和蓄积作用,不释放组胺.
