目的 探讨基于正交试验的肾造瘘管不同固定方案的比较效果。方法 将14Fr硅胶肾造瘘管固定在聚乙烯展板和拉力显示器上，以固定材料、固定方法、面积为3个影响因素，每个因素3个水平，每组进行3次试验再求平均值作为最后拉力值F，共进行9个固定方案共27次试验。利用L9（33）正交试验矩阵研究不同材料（医用橡皮膏、医用透气胶带、医用无纺布胶带）、固定方法（交叉固定法、“工”字固定法和改良“工”字固定法）及面积(16 cm2、24 cm2、32 cm2）对肾造瘘管固定强度的影响。结果 正交试验所选的3种影响因素中，对拉力值影响显著性排序为：材料＞方法＞面积；3种固定材料中，医用橡皮膏固定强度最大。结论 肾造瘘管固定方案中，最佳固定组合为以医用橡皮膏结合改良“工”字法固定，可为临床管道固定方案的选择提供参考。     

微视频在ICU气管套管带管出院患者家属健康教育中的应用

目的探讨应用微视频对ICU气管套管带管出院患者的家属实施健康教育的效果。方法选取2018年9月—2020年9月的100例气管套管带管出院患者的家属,根据随机数字表法将其随机分为对照组和试验组各50例,对照组实施常规健康教育和随访;试验组在此基础上将患者出院后面临的共性问题进行归纳总结,制定并应用微视频对其实施健康教育。分别比较两组患者家属在气管套管相关知识知晓率、气管套管护理操作的准确性以及患者气管切开并发症发生率之间的差异。结果试验组家属在气管套管相关知识的知晓率和护理技能的得分均高于对照组家属(P<0.05),但患者气管切开相关并发症发生率低于对照组(P<0.05)。结论应用微视频实施健康教育可有效提高ICU气管套管带管出院患者家属的管路护理水平,提高患者带管期间的安全性。     

The association of early postoperative desaturation in the operating theatre with hospital discharge to a skilled nursing or long-term care facility

It is unclear which criteria should be used to define readiness for tracheal extubation in the operating theatre. We studied the effects of desaturation in the operating theatre immediately after tracheal extubation on long-term outcomes. Performing a pre-specified, retrospective analysis of 71,025 cases involving previously independent adults undergoing non-cardiac surgery, we evaluated the association between desaturation events (oxygen saturation < 90%) within 10 min of tracheal extubation and adverse discharge (to a skilled nursing facility or long-term care facility). A total of 404 (12.3%) cases with, and 5035 (7.4%) cases without, early postoperative desaturation had an adverse discharge. Early postoperative desaturation was associated with higher odds of being discharged to a nursing facility (adjusted odds ratio 1.36 (95%CI 1.20–1.54); p < 0.001). Increased duration of desaturation augmented the effect (p for trend < 0.001). Desaturation was associated with a higher risk of respiratory, renal and cardiovascular complications as well as increased duration of hospital stay, postoperative intensive care unit admission frequency and cost. Several modifiable factors were associated with desaturation including: high intra-operative long-acting opioid administration; high neostigmine dose; high intra-operative inspired oxygen concentration; and low oxygen delivery immediately before tracheal extubation. There was substantial provider variability between anaesthetists in the incidence of postoperative desaturation unexplained by patient- and procedure-related factors. Early postoperative desaturation is a potentially preventable complication associated with a higher risk of adverse discharge disposition. Anaesthetists may consider developing guidelines to define tracheal extubation readiness that contain postoperative desaturation as an adverse outcome after tracheal extubation.     

Fibreoptic-guided tracheal intubation through i-gel® and LMA® ProtectorTM supraglottic airway devices - a randomised comparison

Fibreoptic-guided tracheal intubation using a supraglottic airway device as a conduit is a technique that can be used in anticipated and unanticipated difficult airway management. Although the i-gel^® supraglottic airway device has been examined for this purpose, the LMA^® Protector^TM, a recently introduced second-generation supraglottic airway device, has not been evaluated for this use in clinical trials. This prospective, randomised clinical trial compared fibreoptic-guided tracheal intubation via i-gel and LMA Protector supraglottic airway devices in two UK hospitals. Patients who were ASA physical status 1 or 2 and undergoing elective surgery requiring tracheal intubation were recruited to the study. A block randomisation list was generated for each study site. The primary outcome measure was time to successful tracheal intubation and secondary outcomes were tracheal intubation success rate, glottic view through flexible fibrescope, ease of tracheal intubation using operator visual analogue score, supraglottic airway device insertion time and insertion success rate. Ninety patients were randomly allocated to each device, and final data analysis was carried out for 92 patients in the i-gel group and 86 patients in the LMA Protector group. Mean (SD) tracheal intubation time in the i-gel and LMA Protector groups were 54.3 (13.8) s and 52.0 (13.0) s, respectively (p = 0.240). There were no significant differences in tracheal intubation success rate, glottic view and ease of tracheal intubation between the two groups. This study demonstrates that the LMA Protector supraglottic airway device is comparable to the i-gel supraglottic airway device as a conduit for fibreoptic-guided tracheal intubation.     

四川省综合医院住院患者非计划拔管风险监控现状调查

目的了解四川省二级及以上综合医院住院患者非计划拔管风险监控管理现状,为建立和完善非计划拔管风险管理模式提供参考。方法采用自行设计的住院患者非计划拔管风险监控调查问卷,对四川省171所二级及以上综合医院进行调查。结果 161所(94.15%)医院开展非计划拔管风险监控,其中157所(97.52%)医院设置有监控机构,均有护理部参与;153所(89.47%)医院有对住院患者非计划拔管的风险评估,160所(93.57%)医院开展非计划拔管风险质量管理督查;10所(5.85%)医院未建立非计划拔管上报机制,36所(21.05%)医院发生非计划拔管后无预警机制,17所(9.94%)医院未开展非计划拔管事件追踪评价。结论四川省二级及以上综合医院开展住院患者非计划拔管风险监控管理相对较好,但在监控机构组成人员、管道监控范围、风险评估工具、风险督查、上报机制、预警机制、追踪评价机制等方面还需进一步完善,以保障非计划拔管管理质量,防范非计划拔管事件发生。

Recomendaciones para la evaluación y manejo de la vía aérea difícil prevista y no prevista de la Societat Catalana d’Anestesiologia,Reanimació i Terapèutica del Dolor,basadas en la adaptación de guías de práctica clínica y consenso de expertos

The Airway Division of the Catalan Society of Anaesthesiology, Intensive Care and Pain Management (SCARTD) presents its latest guidelines for the evaluation and management of the difficult airway. This update includes the technical advances and changes observed in clinical practice since publication of the first edition of the guidelines in 2008.The recommendations were defined by a consensus of experts from the 19 participating hospitals, and were adapted from 5 recently published international guidelines following an in-depth analysis and systematic comparison of their recommendations.The final document was sent to the members of SCARTD for evaluation, and was reviewed by 11 independent experts. The recommendations, therefore, are supported by the latest scientific evidence and endorsed by professionals in the field.This edition develops the definition of the difficult airway, including all airway management techniques, and places emphasis on evaluating and classifying the airway into 3 categories according to the anticipated degree of difficulty and additional safety considerations in order to plan the management strategy. Pre-management planning, in terms of preparing patients and resources and optimising communication and interaction between all professionals involved, plays a pivotal role in all the scenarios addressed.The guidelines reflect the increased presence of video laryngoscopes and second-generation devices in our setting, and promotes their routine use in intubation and their prompt use in cases of unanticipated difficult airway. They also address the increased use of ultrasound imaging as an aid to evaluation and decision-making.New scenarios have also been included, such as the risk of bronchoaspiration and difficult extubation Finally, the document outlines the training and continuing professional development programmes required to guarantee effective and safe implementation of the guidelines.
