Abstract
OBJECTIVE The resorption stage is an important period involving early anti-shock treatment for severe burn patients. We aimed to investigate the quantitative variability in fluid balance during the resorption stage in severe burn patients, and to study its effect on patient outcomes. METHODS We conducted a single-centre retrospective study of 100 severe burn patients with involvement of > 50% total body surface area (TBSA). We extracted clinical data on demographics, clinical characteristics and outcomes; calculated the daily net fluid balance (difference between fluid intake and fluid output) and daily fluid intake/output within one week after injury; and analysed the association between fluid balance and functional outcomes and prognosis. The relative volume (ml/kg/TBSA) was used for the determination of daily fluid volume in this study. RESULTS The daily net fluid balance (ml/kg/TBSA) of the deceased patients on the 4th, 5th, 6th, and 7th days after injury was higher than that of the surviving patients, but the opposite trend was found for the daily fluid output (ml/kg/TBSA). The partial correlation test showed that in the resorption stage of severe burn patients, fluid output was negatively correlated with the index levels of renal function and liver function, CRP level, blood lactic acid (LA) level, frequency of ventilator treatment, and capillary leakage index (CLI), but net fluid balance showed a completely opposite correlation. Moreover, fluid intake was negatively correlated with the index level of renal function and LA level, but positively correlated with the frequency of ventilator treatment. Furthermore, the logistic regression analysis showed that the net fluid balance and fluid output on Day 6 post-injury were independent risk factors for prognosis. CONCLUSION This study suggested that greater fluid output in the resorption stage of severe burn patients was closely related to better outcomes, in addition, a gradually decreasing, lower positive net fluid balance may contribute to the improvement of functional outcomes, which will provide useful information for early fluid management and further prospective clinical study of severe burns.

Influence of time from admission to norepinephrine administration and volume of fluids received on outcomes of patients meeting sepsis-3 criteria: a retrospective study using the MIMIC-IV database. Trauma Surg Acute Care Open 2023; 8:e001024. [PMID: 37073334 PMCID: PMC10106031 DOI: 10.1136/tsaco-2022-001024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Accepted: 02/11/2023] [Indexed: 04/20/2023] Open
Abstract
Objectives Vasopressors are a cornerstone in the management of sepsis, marked by distributive shock often unresponsive to fluid resuscitation. Prior research and clinician surveys have suggested that earlier usage of vasopressors corresponds to improved outcomes. Methods A retrospective cohort was constructed using patient data contained within the Medical Information Mart for Intensive Care-IV database. Analytic cohort included a total of 2079 patients meeting sepsis-3 criteria with a ≥2-point rise in Sequential Organ Failure Assessment score and administered norepinephrine (NE) as first-line vasopressor within 24 hours of admission to the intensive care unit (ICU). Patients receiving other vasopressors or missing documented fluid resuscitation information were excluded. Primary end points included mortality, use of invasive mechanical ventilation and length of stay which were analyzed in a multivariate logistic regression model for the primary effect of time from ICU admission to NE administration using covariates. Results Time to NE use was defined as either early, using <6 hours from time of ICU admission or late using >6 hours to ≤24 hours. Patients who received early NE had significantly lower adjusted odds of mortality (0.75, 95% CI 0.57 to 0.97, p=0.026), higher adjusted odds of invasive mechanical ventilation (1.48, 95% CI 1.01 to 2.16, p=0.045), no significant difference in hospital length of stay (difference in days 0.6 (95% CI -3.24 to 2.04)) and lower ICU length of stay (difference in days -0.9 (95% CI -1.74 to -0.01)), as compared with the late NE group. Conclusion Among patients admitted to the ICU for sepsis, early use of NE was associated with significantly lower odds of mortality but higher odds of mechanical ventilation, and no significant difference in length of hospital stay but less time in the ICU. Furthermore, the volume of fluids received prior to NE use may have a significant impact on optimal NE timing. Level of evidence Level IV-therapeutic care/management.

Association between enterocyte injury and fluid balance in patients with septic shock: a post hoc exploratory analysis of a prospective observational study. BMC Anesthesiol 2021; 21:293. [PMID: 34814831 PMCID: PMC8609797 DOI: 10.1186/s12871-021-01515-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 11/15/2021] [Indexed: 12/29/2022] Open
Abstract
Background The required fluid volume differs among patients with septic shock. Enterocyte injury caused by shock may increase the need for fluid by triggering a systematic inflammatory response or an ischemia-reperfusion injury in the presence of intestinal ischemia/necrosis. This study aimed to evaluate the association between enterocyte injury and positive fluid balance in patients with septic shock. Methods This study was a post hoc exploratory analysis of a prospective observational study that assessed the association between serum intestinal fatty acid-binding protein, a biomarker of enterocyte injury, and mortality in patients with septic shock. Intestinal fatty acid-binding protein levels were recorded on intensive care unit admission, and fluid balance was monitored from intensive care unit admission to Day 7. The association between intestinal fatty acid-binding protein levels at admission and the infusion balance during the early period after intensive care unit admission was evaluated. Multiple linear regression analysis, with adjustments for severity score and renal function, was performed. Results Overall, data of 57 patients were analyzed. Logarithmically transformed intestinal fatty acid-binding protein levels were significantly associated with cumulative fluid balance per body weight at 24 and 72 h post-intensive care unit admission both before (Pearson’s r = 0.490 [95% confidence interval: 0.263–0.666]; P < 0.001 and r = 0.479 [95% confidence interval: 0.240–0.664]; P < 0.001, respectively) and after (estimate, 14.4 [95% confidence interval: 4.1–24.7]; P = 0.007 and estimate, 26.9 [95% confidence interval: 11.0–42.7]; P = 0.001, respectively) adjusting for severity score and renal function. Conclusions Enterocyte injury was significantly associated with cumulative fluid balance at 24 and 72 h post-intensive care unit admission. Enterocyte injury in patients with septic shock may be related to excessive fluid accumulation during the early period after intensive care unit admission.
