Relationship Between Acute Phase Markers and Post-operative Pain in Open Tension-free Inguinal Hernia Repair: An Observational Study

Recruiting

• Conditions: Post Operative Pain; Inguinal Hernia

• Registration Number: NCT06380140
• Lead Sponsor: University of Roma La Sapienza

Brief Summary

Many patients undergoing inguinal hernia repair are prone to developing acute and chronic post-operative pain.

The aim of the study is to show a possible correlation between pain and acute phase proteins in order to:

* predict the severity of pain;

* select most suitable pain relief therapy for the patient.

Detailed Description

The day after surgery, some serum markers are determined by a blood sample.

The markers analyzed are:

* Leukocytes;

* C-reactive protein (CRP);

* D-dimer;

* Fibrinogen;

* Neutrophil-to-Lymphocyte Ratio (NLR).

Pain level is assessed using the NRS scale at different times:

* 1st post-operative day;

* 7th post-operative day;

* One month after surgery;

* Three months after surgery;

* Six months after surgery.

Other data collected for the study are: gender, age, BMI.
