Postoperative respiratory complications, High risk of reintubation patients, Bubble positive expiratory pressure (B-PEP)Abstract
Reintubation and mechanical ventilation in high-risk postoperative patients is a significant issue affecting treatment outcomes. Although current methods such as High-Flow Nasal Cannula (HFNC) and humidification are utilized, the incidence of reintubation remains high, ranging from 7.5% to 24.2%. Therefore, this study aimed to analyze the incidence of reintubation and assess the effectiveness of the Bubble Positive Expiratory Pressure (B-PEP) technique, which combines positive pressure with oscillation during exhalation, in reducing respiratory complications after surgery. This quasi-experimental study (One Group Pre-Post Test) was conducted in high-risk postoperative patients admitted to the surgical intensive care unit of Khon Kaen Hospital between 2022 and 2024. A total of 150 eligible patients were enrolled in the study. The results showed that the incidence of reintubation and mechanical ventilation was 23 cases, accounting for 15.33% (95% CI, 9.50–21.16), with most cases occurring within 24 hours post-extubation. Additionally, there was a statistically significant reduction in dyspnea scores by an average of 2.81 points (95% CI, 1.16–2.62, p-value < 0.05), respiratory rate by 8.74 breaths per minute (95% CI, 7.99–9.48, p-value < 0.05), and an increase in oxygen saturation by 4.06% (95% CI, 3.48–4.63, p-value < 0.05). No significant changes were observed in heart rate or blood pressure. In conclusion, the B-PEP technique is effective and safe in reducing the incidence of reintubation and respiratory complications in high-risk postoperative patients.
