摘要
选ASAI~Ⅱ级LC300例,用双盲法按快诱时不同吸氧法分为慢速组、快速组和对照组各100例,对胃气胀影响LC术野进行比较研究。术前禁食12h,均不置胃管;常规给术前药;全能麻醉机面罩吸入纯氧去氮;Vt12ml/kg;f20bpm;t,慢速组>1.5S,快速组<1S,对照组1~15S;PImax,慢速组<15kpa,快速组>2kpa,对照组1.5~2kpa;快诱插管后,腹内注入CO2形成气腹,腹压平稳维持在18~2kpa,置入腹腔镜观察胃气胀对LC术野影响的程度。将快速组、慢速组和对照组进行相互对应比较,结果慢速组I°Ⅱ°(优良组)明显多于快速组(89:13)和对照组(89:45)。经X2检验统计学处理均有显著差异(P<0.01),提示慢速组对LC术野的影响明显少于和轻于快速组和对照组。说明全麻快诱插管不同吸氧法,速度和压力对引起胃气胀影响LC术野有密切相关性。
Acting on different inspiratory oxygen methods of induction and by double blind method,the author of the paper studied the affection of stomach air expanse to LC's operative field through dividing the selective 300LC cases (ASAⅠ°-Ⅱ°)into slow-speed team ,fast-speed team and control team (100cases for each team).Patients were forbidden to have food for 12 hours before operation and were given nomal preoperative medicine.No stomach tubes were placed and general anesthetic machine was used to make patients inspire pure oxygen and remove nitrogen through mask.V T12ml.kg -,f20.t>1.5s in show team,t<1s in fast team and t lay in 1-1.5s in controlteam.Pimax<1.5kPa in slow tean,p imax >2kpa in fast team,and pimax lay in 1.5-2kpa in control team.After fast induction and endotracheal intubation,co 2-abdomen was formed after carbon dioxide being injected into abdomino cavity.After a laparos cope was placed into patient's abdomino cavity,the affection to LC's operative field could be observed when the pressure of co 2-abdomen was maitained at 1.8-2kpa.Compaing slow team,fast team and control team with each other.the anthor get the results that Ⅰ°+Ⅱ°(good orbetler team)in slow team were clearly more than that of fast team (89:13)and that of control team (89:45),significant differences were made by x 2 test. The results showed the affection to operative field of slow team was less and lighter than that of fast team and control team.The author of the paper conces to a conchlsion that speed,presure,and the methods of different inspiratory oxygen in fast induchon of endotracheal intubation have close relationship with the affection of stomach air expanse to LC's operative field.
