Airway management is a critical intervention for patients with airway compromise, respiratory failure, and cardiac arrest. Many EMS agencies use drug-assisted airway management (DAAM) - the administration of sedatives alone or in combination with neuromuscular blockers - to facilitate advanced airway placement in patients with airway compromise or impending respiratory failure who also have altered mental status, agitation, or intact protective airway reflexes. While DAAM provides several benefits including improving laryngoscopy and making insertion of endotracheal tubes and supraglottic airways easier, DAAM also carries important risks. NAEMSP recommends:DAAM is an appropriate tool for EMS clinicians in systems with clear guidelines, sufficient training, and close EMS physician oversight. DAAM should not be used in settings without adequate resources.EMS physicians should develop clinical guidelines informed by evidence and oversee the training and credentialing for safe and effective DAAM.DAAM programs should include best practices of airway management including patient selection, assessmenct and positioning, preoxygenation strategies including apneic oxygenation, monitoring and management of physiologic abnormalities, selection of medications, post-intubation analgesia and sedation, equipment selection, airway confirmation and monitoring, and rescue airway techniques.Post-DAAM airway placement must be confirmed and continually monitored with waveform capnography.EMS clinicians must have the necessary equipment and training to manage patients with failed DAAM, including bag mask ventilation, supraglottic airway devices and surgical airway approaches.Continuous quality improvement for DAAM must include assessment of individual and aggregate performance metrics. Where available for review, continuous physiologic recordings (vital signs, pulse oximetry, and capnography), audio and video recordings, and assessment of patient outcomes should be part of DAAM continuous quality improvement.
气道管理是气道受损、呼吸衰竭和心脏骤停患者的关键干预措施。许多急救医疗服务机构使用药物辅助气道管理(DAAM)——单独或联合使用镇静剂和神经肌肉阻滞剂——来促进气道受损或即将发生呼吸衰竭且意识状态改变、躁动或完整保护气道反射的患者进行高级气道放置。虽然 DAAM 提供了许多益处,包括改善喉镜检查,使气管内导管和 Supraglottic 气道更容易插入,但 DAAM 也存在重要风险。NAEMSP 建议:在有明确指南、充足培训和密切急救医生监督的系统中,DAAM 是急救医疗服务临床医生的合适工具。在没有足够资源的情况下,不应使用 DAAM。急救医生应根据证据制定临床指南,并监督安全有效的 DAAM 培训和认证。DAAM 计划应包括气道管理的最佳实践,包括患者选择、评估和定位、预充氧策略,包括无通气氧合、监测和处理生理异常、药物选择、插管后镇痛和镇静、设备选择、气道确认和监测以及救援气道技术。在进行 DAAM 后,必须使用波形二氧化碳描记术确认并持续监测气道放置情况。急救医疗服务临床医生必须具备必要的设备和培训,以管理 DAAM 失败的患者,包括球囊面罩通气、Supraglottic 气道设备和手术气道方法。DAAM 的持续质量改进必须包括对个体和总体绩效指标的评估。在有条件进行审查的情况下,连续的生理记录(生命体征、脉搏血氧饱和度和二氧化碳描记术)、音频和视频记录以及患者结局评估应成为 DAAM 持续质量改进的一部分。
