Background
Intravenous fluid optimization is an essential component of managing patients in a critical care setting. A cumulative positive fluid balance is consistent with poor outcomes in patients admitted to the intensive care unit (ICU). The overall utility of net cumulative fluid balance as a surrogate for assessing fluid overload has been interrogated.
Materials and methods
This study was a prospective single-center observational study, which was done to correlate body weight changes with fluid balance in ICU patients and evaluate its impact on clinical outcomes. Inclusion criteria consisted of adult patients who were admitted to the critical care unit on specialized beds with integrated weighing scales between September 2017 and December 2018. The evaluation of the effect of changes in body weight on ICU survival was the primary objective of the study.
Results
We enrolled 105 patients in this study. The ICU mortality was 23.80% with non-survivors showing more weight gain than the survivors. Statistically significant weight gain was documented in the non-survivors on days 3 and 4 (1.9 vs 1.05;
p
= 0.0084 and 2.6 vs 1.6;
p
= 0.0030) of ICU admission. Non-survivors had greater cumulative positive fluid balance on fourth, fifth, and sixth days post-ICU admission when compared to survivors (3586 vs 1659 mL,
p
= 0.0322; 5418 vs 1255 mL,
p
= 0.0017; and 5430 vs 2305 mL
p
= 0.0264, respectively). In multivariate regression analysis, cumulative fluid balance did not correlate with days on mechanical ventilation or length of stay in ICU. Changes in body weight and cumulative fluid balance showed a good correlation.
Conclusion
In patients admitted to the ICU, weight gain on third and fourth days of admission is concordant with increased ICU mortality. Body weight changes were seen to correlate well with the cumulative fluid balance.

We present a case of bronchial injury following bougie-assisted endotracheal intubation in a patient with difficult airway scheduled to undergo right percutaneous nephrolithotomy under general anaesthesia. The patient developed pleuritic pain along with right pleural effusion on the third postoperative day which was diagnosed by the anaesthesiologist who was following up the patient for airway trauma-associated complications. However, the patient was diagnosed to have a nephropleural fistula, a rare complication of supracostal access to percutaneous nephrolithotomy, which was managed successfully.
Prone position ventilation has been shown to decrease mortality and improve oxygenation in ARDS patients. With best of our knowledge, no study reported physiological effect of prone position in SARS- CoV-2 infected ARDS patients. In this prospective observational study, data of n=20 consecutive laboratory confirmed SARS- CoV-2 patients with severe ARDS as per Berlin definition was included. Data of 20 patients analyzed with a median (Interquartile range, IQR) age of 56 (45.5- 67) y and median (IQR) P/F ratio of 56 (54- 66) with a median (IQR) PEEP of 12 (12- 14) before initiation of prone position. Seventy-five percentage (95% CI 53.1- 88.8) patients were prone responders at 16h prone session and 50 (95% CI 29.9- 70.1) % patients were sustained responders. There was a significant decrease in plateau airway pressure (p<0.0001), peak airway pressure (p<0.0001) and driving pressure(p<0.0001) and increase in static compliance (p=0.001), P/F ratio (p<0.0001), PaO2 (p=0.0002)and SpO2 (p=0.0004) at 4h and 16h since initiation of prone session and also after return of supine position. Prone position in SARS- CoV-2 infected severe ARDS patients is associated with improvement in lung compliance and oxygenation in two- third of the patients and persisted in half of the patients.
