Efficacy Of G5 Vibracare On Lung Compliance, Partial Pressure Of Oxygen, Dead Space Tidal Volume Fraction And Quantity Of Secretions In Mechanically Ventilated Organophosphorus Poisoning Patients: A Randomized Controlled Trial

Abstract

Objective: Conventional Chest physiotherapy includes manual chest percussion, manual chest vibration, postural drainage and suctioning. The objective of this research is to determine the effectiveness of G5 Vibracare on lung compliance, partial pressure of oxygen, dead space tidal volume fraction and Quantity of secretions in mechanically ventilated organophosphorus poisoning patients.

Material and Methods: The present study was a parallel group, randomized, controlled trial registered in Clinical Trial Registry of India (CTRI/2018/07/015074). 50 Mechanically ventilated Organophosphorus poisoning patients in medical intensive care unit of both genders of age between 20-80 years were allocated in 2 groups. Experimental group received Mechanical chest vibration by a device called G5 Vibracare along with conventional chest physiotherapy followed by suctioning for a total duration of 30 minutes twice a day. Control group consists of conventional chest physiotherapy which included manual chest percussion, manual chest vibration, and suctioning. The outcome measures evaluated in both groups were Ventilator Parameters (Static Compliance, Dynamic Compliance, VD/VT), Oxygenation Parameters (PaO2) & Quantity of secretions were noted on day 1 and on the day of extubation.

Results: Experimental Group (G5 Vibracare and Conventional Chest Physiotherapy) showed a significant difference in Quantity of secretions (p value - .049) than the control group between the groups. There was no statistically significant difference in Static Compliance, Dynamic compliance, VD/VT, PaO2 between the groups as both groups had similar clinical significance

Conclusion: The study concluded that Experimental Group (G5 Vibracare and Conventional Chest Physiotherapy) is helpful in clearing the secretions in the lung due to higher frequency (20Hz) than the control group.
