Abstract

Introduction: International guidelines on aid prior to invasive procedures usually generate longer aid than in intensive care (IT) patients. This fact represents a high risk of malnutrition and, consequently, a worse prognosis. The objective of the present investigation was to analyze the degree of association between the fasting time prior to tracheostomy of patients under mechanical ventilatory assistance (MVA) and the appearance of pneumonia. Methods: Retrospective cohort study that included patients admitted to our IT from 10/01/2018 to 08/31/2022 and with a tracheostomy performed. Two cohorts were defined characterized by fasting ≤3 hours vs. >3 hours. Fisher's exact test and Mann-Whitney test were used for bivariate analysis. A p value <0.05 was shown to be significant. Results: 141 patients were hospitalized with a tracheostomy, 9 were excluded, leaving 132 patients. The cohort with fasting ≤3 hours was made up of 15 patients and the one with fasting >3 hours was made up of 117, the latter presented an average fast of 2.5 hours (IR 2-3), days of AVM prior to the procedure of 13 days (IR 12-18), while the other cohort presented an average fast of 6 hours (IR 5-8), days of AVM prior to the procedure of 12 days (IR 10-14.5). When analyzing the association between the type of fasting and the appearance of pneumonia, an OR of 0.958 (95% CI: 0.32-2.87) was obtained, p value of 0.743. Conclusions: No significant differences were found regarding fasting time and the appearance of pneumonia as referred to in the international literature.
在强化治疗中实施气管造口术前短期和长期禁食:一项回顾性研究
导言:国际指南规定,侵入性手术前的辅助时间通常比重症监护(IT)患者的辅助时间更长。这一事实表明,营养不良的风险很高,因此预后较差。本研究旨在分析机械通气辅助(MVA)患者气管切开术前禁食时间与肺炎出现之间的关联程度。研究方法回顾性队列研究,包括 2018 年 1 月 10 日至 2022 年 8 月 31 日期间入住本院 IT 并实施气管切开术的患者。根据空腹时间≤3 小时与>3 小时定义了两个队列。双变量分析采用费雪精确检验和曼-惠特尼检验。P值为 3 小时的有 117 人,后者的平均禁食时间为 2.5 小时(IR 2-3),术前 AVM 天数为 13 天(IR 12-18),而另一个队列的平均禁食时间为 6 小时(IR 5-8),术前 AVM 天数为 12 天(IR 10-14.5)。在分析禁食类型与肺炎出现之间的关系时,得出 OR 值为 0.958(95% CI:0.32-2.87),P 值为 0.743。结论禁食时间与肺炎的出现在国际文献中未发现明显差异。
