Lipid Profile as a Predictive Marker for Organ Dysfunction after Thoracoabdominal Surgery: A Cross-sectional Study

Area of Science:

• Biochemistry
• Clinical Medicine
• Surgical Outcomes

Background:

• Plasma total cholesterol (TC) is a negative acute phase reactant.
• Serum cholesterol levels often decrease in pathological conditions like trauma, sepsis, burns, liver dysfunction, and post-surgery.
• Investigating lipid profiles' role in predicting post-surgical organ dysfunction is crucial.

Purpose of the Study:

• To explore the association between lipid profiles and organ dysfunction following thoracoabdominal surgery.
• To determine if lipid markers can predict patient outcomes, including mortality and length of stay.

Main Methods:

• A cross-sectional study of patients admitted to the ICU post-thoracoabdominal surgery.
• Measurement of serum total cholesterol (TC), LDL-C, HDL-C, triglycerides (TG), and albumin.
• Logistic regression analysis to evaluate the relationship between lipid markers and organ dysfunction, mortality, and clinical outcomes.

Main Results:

• Elevated serum TC significantly increased the risk of mortality, renal, liver, and respiratory dysfunction.
• Lower levels of LDL-C, HDL-C, and TG were associated with adverse outcomes.
• Lipid profiles were linked to length of stay, mechanical ventilation duration, and vasopressor use.

Conclusions:

• Serum TC is a risk factor for post-surgical mortality and organ dysfunction.
• LDL-C, HDL-C, and TG demonstrate a protective role against adverse outcomes.
• Lipid profiles are valuable indicators for assessing patient prognosis after surgery.
