FFP:RBC resuscitation ratio and post-shock fluid uptake

Area of Science:

• Trauma resuscitation
• Critical care medicine
• Hemorrhagic shock management

Background:

• Optimizing fluid resuscitation in severely injured patients is critical.
• The balance of blood products and crystalloids influences patient outcomes.
• Understanding the impact of resuscitation ratios on postoperative recovery is essential.

Purpose of the Study:

• To evaluate how fresh frozen plasma (FFP) to red blood cell (RBC) and balanced electrolyte solution (BES) to RBC ratios affect postoperative fluid uptake, fluid needs, weight gain, and hypoproteinemia.
• To determine the predictive value of resuscitation ratios on patient recovery.
• To investigate the relationship between shock severity and resuscitation strategies.

Main Methods:

• Retrospective analysis of 316 severely injured, hypotensive patients.
• Correlation of in-hospital resuscitation ratios (FFP:RBC, BES:RBC) with postoperative outcomes (phase 2 duration, BES needs, weight gain, hypoproteinemia).
• Assessment of shock time, vital signs, and laboratory values.

Main Results:

• Shock time strongly correlated with resuscitation volumes and all phase 2 outcomes.
• No significant correlation found between FFP:RBC or BES:RBC ratios and phase 2 hypoproteinemia or weight gain.
• FFP:RBC ratio positively correlated with phase 2 duration and BES needs; BES:RBC ratio inversely correlated with phase 2 duration and BES needs.

Conclusions:

• Shock severity, indicated by shock time and resuscitation volumes, predicts postoperative outcomes.
• Contrary to some findings, higher FFP:RBC ratios in the OR were associated with increased phase 2 duration and BES needs.
• Higher BES:RBC ratios were associated with decreased phase 2 duration and BES needs.
