Abstract

Objective: to describe the Diaphragmatic Rapid Shallow Breathing Index (D-RSBI) in patients undergoing weaning from mechanical ventilation at the Center for Critical care medicine of Bach Mai Hospital. Subjects: Patients indicated for weaning from mechanical ventilation at the Center for Critical Care Medicine of Bach Mai Hospital from July 2023 to August 2024. Method: Prospective descriptive study. Eligible patients who met the criteria for weaning from mechanical ventilation were subjected to weaning. Respiratory rate and diaphragmatic ultrasound index were collected 30-60 minutes after the initiation of weaning, and the D-RSBI index was calculated. Diaphragmatic ultrasound was performed using a convex and linear probe ultrasound machine by a physician with ultrasound certification, video made and verified by radiologist. Results: A study of 33 patients revealed that the male-to-female ratio was twice as high in males compared to females. There were no statistically significant differences in clinical and paraclinical indices. The success rate for weaning off the ventilator was 42.4% (n=14). The primary cause of failure was poor cough production, accounting for 63.2% (n=12). The mean values for DE-RSBI on the right, DTF-RSBI on the right, DE-RSBI on the left, and DTF-RSBI on the left were 2.03±0.87; 0.78±0.51; 1.99±0.85; and 0.86±0.39, respectively. There were no statistically significant differences in D-RSBI indices between age groups and genders. Conclusion: The DE-RSBI and DTF-RSBI indices are equivalent between the left and right sides. According to age and gender, there is no statistically significant difference in the indices.
