CHINA: According to a report published in the International Journal of Chronic Obstructive Pulmonary Disease, the detection of procalcitonin can direct the choice of ventilation switching points in sequential mechanical ventilation therapy for patients with COPD experiencing respiratory failure in the acute exacerbation stage.
Among senior adults, chronic obstructive pulmonary disease (COPD) is one of the most prevalent respiratory disorders.
"Admission to an intensive care unit (ICU) for monitoring and mechanical ventilation treatment is one of the most crucial aspects of clinical treatment for patients with an acute exacerbation of COPD coupled with respiratory failure. The most frequent form of treatment for acute respiratory failure and COPD exacerbation is sequential mechanical ventilation, which has been shown in clinical studies to be significantly more effective and safer than traditional mechanical ventilation, "the team lead by Fang Ding, Department of Geriatrics, Hengshui People's Hospital, asserted.
The smooth and safe transition from invasive mechanical ventilation to non-invasive ventilation, however, is a crucial therapeutic concern.
The authors intended to evaluate the procalcitonin (PCT) guiding value for the selection of ventilation switching points in sequential mechanical ventilation for patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) and respiratory failure, and to serve as a guide for the optimization of mechanical ventilation for patients with COPD and respiratory failure.
The trial enrolled 160 patients who had sequential mechanical ventilation therapy for a COPD acute exacerbation complicated by respiratory failure. Two groups of 80 people each were created among them. For sequential mechanical ventilation treatment in the control group, the critical point of the pulmonary infection observation window (PIC) was employed as the switching point, but for sequential mechanical ventilation treatment in the observation group, the PCT clinical node was used. Intense care unit (ICU) treatment time, non-invasive mechanical ventilation time, total mechanical ventilation time, complication rate, and prognosis were compared for the two groups.
Key highlights of the study:
After one day of treatment, there was no discernible difference between the two groups in terms of respiratory rate, heart rate, arterial systolic pressure, arterial oxygen partial pressure, arterial carbon dioxide partial pressure, or pH value.
There were substantial differences between the two groups in terms of invasive mechanical ventilation time, non-invasive mechanical ventilation time, total mechanical ventilation time, ICU treatment time, and the occurrence of complications (P = 0.0001).
In both the control and observation groups, the death rate was 6.25%, and there was no statistically significant difference in the prognosis between the two groups (P > 0.05).
In comparison to the control group, the observation group's complication rate was decreased (P< 0.05).
The researchers concluded that detecting PCT can efficiently reduce the misvaluation of PIC switching points, allowing patients to establish stable standards of judgment and efficiently enhancing the effectiveness and safety of mechanical ventilation treatment for patients in the acute exacerbation stage.
