Crystalloid solutions for intravascular volume replacement.","authors":"D L Hancock","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>There is growing interest in the use of hypertonic crystalloid solutions for intravascular volume replacement. Such solutions rapidly restore nutrient blood flow to vital organs by a combination of increased perfusion pressure and vascular dilation. The addition of colloid to the solution appears to improve survival by limiting the tissue damage caused by ischemic injury and may avert the development of multisystem organ failure. Low cost and long shelf life make hypertonic solutions attractive for acute resuscitation after major trauma, but further investigations are warranted as to their efficacy and safety in the clinical setting.</p>","PeriodicalId":80191,"journal":{"name":"The American journal of anesthesiology","volume":"22 2","pages":"71-7"},"PeriodicalIF":0.0,"publicationDate":"1995-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21021988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The laryngeal mask airway. Safety, efficacy, and current use. 喉罩气道。安全性、有效性和当前使用情况。
D K Springer, J S Jahr
{"title":"The laryngeal mask airway. Safety, efficacy, and current use.","authors":"D K Springer,&nbsp;J S Jahr","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>In 1983, the laryngeal mask airway (LMA) was introduced as a new airway device. It can be inserted without the aid of a laryngoscope or neuromuscular blockade. Compared with the face mask, the LMA allows for a more \"hands-free approach\" to airway management providing the anesthesiologist the freedom of not holding a mask. In addition, the LMA is more effective than the face mask, with or without a Guedel airway, during emergency resuscitation in situations where endotracheal intubation is difficult or not possible. The LMA seems to provide better oxygenation than the face mask; but unlike the endotracheal tube, it does not protect the airway from aspiration of gastric contents if regurgitation occurs. For this reason, it is believed that the LMA should not be used in place of an endotracheal tube during emergency rescue, but rather as an adjunct to airway management prior to intubation. It is possible that the risk of regurgitation with or without aspiration may be minimized if proper screening of patients is employed prior to use of the LMA. The current literature concerning its safety and efficacy is reviewed.</p>","PeriodicalId":80191,"journal":{"name":"The American journal of anesthesiology","volume":"22 2","pages":"65-9"},"PeriodicalIF":0.0,"publicationDate":"1995-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21022080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NPO after midnight before elective surgery is no longer common practice for the majority of anesthesiologists. 对于大多数麻醉师来说,在选择性手术前的午夜之后进行NPO已不再是常见的做法。

The 95% confidence intervals for these percentages were calculated by using the normal approximation of a binomial distribution.
