The predictive role of delayed cutaneous hypersensitivity testing in postoperative complications

Area of Science:

• Immunology
• Surgical Outcomes

Background:

• Postoperative septic complications pose significant risks.
• Predictive markers for these complications are essential for patient management.

Purpose of the Study:

• To evaluate the predictive value of ten parameters, including delayed cutaneous hypersensitivity (DCH) testing, for postoperative septic complications.
• To assess the influence of operative factors on complication rates.

Main Methods:

• A study involving 302 patients undergoing surgical treatment.
• Comparison of 42 patients with postoperative complications against 260 patients without complications.
• Evaluation of parameters including DCH testing, hemoglobin, leukocyte count, serum albumin, total protein, blood sedimentation rate, age, and sex.

Main Results:

• Hemoglobin, leukocyte count, serum albumin, total protein, blood sedimentation rate, age, and sex did not predict complications.
• DCH testing showed increased complication rates in anergic patients (20.6%) compared to normergic patients (7.5%).
• Complication rates increased with operation length and severity, with DCH testing differentiating risk in severe, long operations (normergic: 8.6%, hypoergic: 36.6%, anergic: 37.5%).

Conclusions:

• DCH testing is a valuable predictor of postoperative septic complications, particularly in patients experiencing significant operative trauma.
• Assessing both host defense mechanisms (via DCH) and environmental factors (operative trauma) is vital for accurate operative risk assessment.
