Prolonged healing of tracheostomy after decannulation has a negative impact on respiration, hygiene, cosmetics, and social life. Even so, evidence-based observations of tracheostoma healing time are lacking. Therefore, the aim of this study was to determine tracheostomy wound healing time after decannulation.
In this prospective observational cohort study, we included 30 subjects undergoing decannulation following prolonged mechanical ventilation via tracheostomy. Our primary endpoint was tracheostomy healing time defined as time from decannulation to airtight healing. To identify any factors related to healing time, we included information about patient demographics, comorbidities, tracheostomy method, tube size, and intubation time. All subjects were observed daily until their tracheostomy wound had healed.
The median tracheostomy healing time was 6.5 (1-22) days. The duration of tracheal cannulation was the only factor significantly correlated with prolonged healing (p=0.03). Four patients were subjected to recannulation shortly after decannulation due to hypercapnia, respiratory failure, secretion accumulation, or self-decannulation. All wounds achieved complete spontaneous airtight closure.
Duration of spontaneous tracheostomy closure after decannulation was 1-22 days, and closure time correlated with duration of cannulation.
拔管后气管造口愈合时间延长对呼吸、卫生、美观及社交生活均有负面影响。即便如此，目前仍缺乏关于气管造口愈合时间的循证观察。因此，本研究旨在确定拔管后气管造口的愈合时间。
在这项前瞻性观察性队列研究中，我们纳入了30例经气管造口长期机械通气后接受拔管的受试者。我们的主要终点是气管造口愈合时间，定义为从拔管到气密愈合的时间。为了确定与愈合时间相关的任何因素，我们纳入了有关患者人口统计学、合并症、气管造口方法、导管尺寸和插管时间的信息。所有受试者每天接受观察，直至其气管造口伤口愈合。
气管造口愈合时间的中位数为6.5（1 - 22）天。气管插管时间是与愈合时间延长显著相关的唯一因素（p = 0.03）。4例患者在拔管后不久因高碳酸血症、呼吸衰竭、分泌物积聚或自行拔管而再次插管。所有伤口均实现完全自发气密闭合。
拔管后气管造口自发闭合时间为1 - 22天，且闭合时间与插管时间相关。
