Abstract

Introduction: By administering inferior vena cava (IVC) directed fluid, it is possible to avoid the use of additional fluid and fluid overload in patients with septic shock (SS) and sepsis-induced hypoperfusion (SIH).

Methodology: In patients with SIH and SS, we conducted prospective observational research on fluid therapy. A time-motion trace of the IVC diameter was created using M-mode imaging. The ability to predict fluid responsiveness was based on the IVC collapsibility index (cIVC) > 40%. Participants were randomised into 2 groups using a permuted block-of-four randomization list, with the investigators being blinded prior to patient allocation. They were split equally between the usual-care (UC) group, which received sepsis-guided fluid treatment, and the interventional ultrasound-guided fluid therapy (UGFT) group.

Results: The average age of the participants was 63.2 years (62.8 years for the UGFT group and 63.7 years for the UC group). Co-morbid health conditions were practically the same in both arms at baseline. Prior to enrolment, both groups received the same quantity of fluid as part of resuscitation (UGFT arm received 2.4 0.6 L, UC group received 2.2 0.7 L). The UGFT group outperformed the UC group with a P value of 0.02 due to a significantly lower positive fluid balance after 72 hours of ICU discharge (-1.37 L), which rendered the UGFT group superior to the UC group. Even after accounting for the fluids consumed before enrolment, there was still a sizable difference in the fluids infused. When the pre-enrolment fluids were counted at 72 hours, UGFT participants still displayed a decreased positive fluid balance. However, there was no discernible difference in the 30-day mortality rate overall (6.3% difference, UGFT: 15.7%, and UC: 22.0%).

Conclusions: In contrast to the UC group, the UGFT arm of our study demonstrated a statistically significant benefit of Point of Care USG (POCUS) guided fluid therapy during resuscitation in sepsis in reducing the positive fluid balance in 72 hours, preventing fluid overload, and reducing the need for dialysis and invasive ventilation. However, there was no statistically significant variation in the 30-day mortality rate.
