Peripheral Perfusion Index-guided Fluid Resuscitation for Preventing Acute Skin Failure in Elderly Critically Ill Patients
Sponsor: Ying Wang
Summary
This prospective, randomized, controlled trial aimed to evaluate whether fluid resuscitation guided by the Peripheral Perfusion Index (PPI) could reduce the incidence of Acute Skin Failure (ASF) in elderly critically ill patients. A total of 216 patients aged ≥65 years with sepsis or other types of shock requiring early aggressive fluid resuscitation were enrolled and randomly assigned in a 1:1 ratio to either the PPI-guided resuscitation group or the conventional resuscitation group. The intervention group targeted maintaining PPI ≥1.4 in addition to conventional hemodynamic goals, while the control group followed standard resuscitation protocols. The primary outcome was the incidence of ASF within 7 days of ICU admission, diagnosed according to NPUAP/EPUAP (2014) criteria. Secondary outcomes included time to ASF occurrence, lactate clearance, cumulative fluid balance, organ function, and long-term prognosis.

Peripheral Perfusion Index-guided Fluid Resuscitation Protocol
In addition to achieving conventional macro-hemodynamic goals (mean arterial pressure ≥65 mmHg, etc.), a resuscitation protocol targeting a Peripheral Perfusion Index (PPI) value ≥1.4 is implemented. PPI is continuously monitored via a finger pulse oximeter. If PPI remains below 1.4 for \>30 minutes, a fluid responsiveness assessment (e.g., passive leg raising test) is performed. Fluid boluses (balanced crystalloid) are administered only if the patient is fluid-responsive. Otherwise, vasoactive agents are optimized.
Conventional Goal-Directed Fluid Resuscitation
Fluid resuscitation is performed according to the Surviving Sepsis Campaign International Guidelines. Resuscitation targets include: mean arterial pressure ≥65 mmHg, central venous pressure 8-12 mmHg, urine output ≥0.5 mL·kg-¹·h-¹, and normalization/decreasing trend of serum lactate. The type, rate, and volume of fluid administration are determined by the treating physician based on these standard macro-hemodynamic and perfusion parameters.
