Volume-based subglottic secretion drainage: a randomized controlled trial.

BACKGROUND

This study proposed to explore individual management mode for patients with subglottic secretion drainage.

METHODS

Randomly chosen within the hospital ICU 68 patients from 7 April to 15 June 2023, all the patients randomly assigned to the control group or observation group, and control group adopts the model of intermittent drainage management, observation group based on the volume of subglottic secretion in patients with individualized management, and then analysis the two groups of patients clinical trial results.

RESULTS

The clinical trial results showed that there were statistically significant differences (<0.05) between the control group and the observation group in the incidence of tube blockage events (11 vs. 2), average diurnal pumping frequency (9 vs. 7, 5 vs. 4) between the two groups and the patient satisfaction scores (6 vs. 7), In the partial mucosa injure (22 vs 19) and VAP (5 vs. 1) there were no statistically significant difference (>0.05). Although there was no statistically significant difference (>0.05) in the average aspiration volume (12.68±3.41 vs. 12.19±2.68, 8 vs. 8) between the two groups, but the management mode of the observation group indicated that based on patient secretion volume was more consistent with the characteristics of the body's diurnal metabolic differences, because there was a big difference between the average total amount of daytime and nighttime suction between the two groups.

CONCLUSION

Individualized management based on the volume of subglottic secretions produced by patients can further optimize the airway management of patients and reduce the risk of adverse events of subglottic secretions aspiration.
