Comparison of Extubation Techniques in ICU Patients
Objective
The goal of this study was to compare three different extubation techniques for patients on mechanical ventilation in the ICU.
Methods
This was a prospective randomized controlled study involving patients from the First Affiliated Hospital of Guangxi Medical University between July and November 2023. Patients were randomly assigned to one of three groups:
- Negative Pressure Group
- Positive Pressure Group 1 (7 cmH2O pressure support and 5 cmH2O PEEP)
- Positive Pressure Group 2 (15 cmH2O pressure support and 10 cmH2O PEEP)
Each group had 45 patients. The study measured complications related to extubation, such as:
- Tachypnea
- Severe cough
- Sore throat
- Upper airway obstruction
- Extubation failure
- Hypoxemia
- Hypercapnia
Secondary measures included heart rate and blood pressure changes before and after extubation.
Results
Out of the initial participants, 42 patients were analyzed in each group. Key findings include:
- Significant differences in complications among the groups, with lower rates in the positive pressure groups compared to the negative pressure group.
- For example, tachypnea occurred in 7.14% and 9.52% of positive pressure group patients, compared to 33.33% in the negative pressure group.
- No significant differences in extubation failure rates were found.
- Positive pressure groups maintained better blood oxygen saturation levels post-extubation.
Conclusions
Positive pressure extubation is more effective than negative pressure extubation in reducing complications for ICU patients on mechanical ventilation. It helps maintain stable blood oxygen levels after extubation and is recommended for clinical use.
Practical Solutions and Value
Implementing positive pressure extubation techniques can enhance patient safety and outcomes in the ICU. Additionally, using AI-driven platforms like DocSym can streamline clinical processes, improve patient care, and reduce paperwork.
