The timing of tracheotomy in patients requiring mechanical ventilation is unknown. The effects of early percutaneous dilational tracheotomy compared with delayed tracheotomy in critically ill medical patients needing prolonged mechanical ventilation were assessed.
Prospective, randomized study.
Medical intensive care units.
One hundred and twenty patients projected to need ventilation >14 days.
None.
Patients were prospectively randomized to either early percutaneous tracheotomy within 48 hrs or delayed tracheotomy at days 14-16. Time in the intensive care unit and on mechanical ventilation and the cumulative frequency of pneumonia, mortality, and accidental extubation were documented. The airway was assessed for oral, labial, laryngeal, and tracheal damage. Early group showed significantly less mortality (31.7% vs. 61.7%), pneumonia (5% vs. 25%), and accidental extubations compared with the prolonged translaryngeal group (0 vs. 6). The early tracheotomy group spent less time in the intensive care unit (4.8 +/- 1.4 vs. 16.2 +/- 3.8 days) and on mechanical ventilation (7.6 +/- 2.0 vs. 17.4 +/- 5.3 days). There was also significantly more damage to mouth and larynx in the prolonged translaryngeal intubation group.
This study demonstrates that the benefits of early tracheotomy outweigh the risks of prolonged translaryngeal intubation. It gives credence to the practice of subjecting this group of critically ill medical patients to early tracheotomy rather than delayed tracheotomy.
需要机械通气的患者进行气管切开术的时机尚不清楚。评估了在需要长时间机械通气的重症内科患者中,早期经皮扩张气管切开术与延迟气管切开术相比的效果。
前瞻性随机研究。
内科重症监护病房。
预计需要通气超过14天的120名患者。
无。
患者被前瞻性随机分为在48小时内进行早期经皮气管切开术或在第14 - 16天进行延迟气管切开术。记录在重症监护病房的时间、机械通气时间以及肺炎、死亡率和意外拔管的累积发生率。评估气道的口腔、唇部、喉部和气管损伤情况。与延迟经喉气管切开术组相比,早期组的死亡率(31.7%对61.7%)、肺炎发生率(5%对25%)和意外拔管率显著更低(0对6)。早期气管切开术组在重症监护病房的时间(4.8±1.4天对16.2±3.8天)和机械通气时间(7.6±2.0天对17.4±5.3天)更少。延迟经喉插管组口腔和喉部的损伤也明显更多。
本研究表明早期气管切开术的益处超过延迟经喉插管的风险。这支持了对这组重症内科患者进行早期气管切开术而非延迟气管切开术的做法。
