Comparison of C-Reactive Protein Levels in Traumatic Brain Injury Patients Undergoing Craniotomy With and Without Dexmedetomidine

Differences in C-Reactive Protein Levels Between Traumatic Brain Injury Patients Receiving Dexmedetomidine and Those Not Receiving Dexmedetomidine Undergoing Craniotomy at Prof. Dr. Margono Soekarjo Regional General Hospital, Purwokerto

Traumatic Brain Injury (TBI) is a major cause of morbidity and mortality and is often associated with a systemic inflammatory response after surgery. C-reactive protein (CRP) is a commonly used biomarker to assess inflammation. Dexmedetomidine is an anesthetic adjuvant that may have anti-inflammatory effects.

This study aims to compare C-reactive protein levels in traumatic brain injury patients undergoing craniotomy who receive dexmedetomidine with those who do not receive dexmedetomidine. The study is conducted at Prof. Dr. Margono Soekarjo Regional General Hospital, Purwokerto. The results of this study are expected to provide information on the potential effect of dexmedetomidine on postoperative inflammatory response in traumatic brain injury patients.

This study is an interventional study conducted in traumatic brain injury patients undergoing craniotomy at Prof. Dr. Margono Soekarjo Regional General Hospital, Purwokerto. Eligible patients are divided into two groups: patients who receive dexmedetomidine as part of perioperative management and patients who do not receive dexmedetomidine.

C-reactive protein levels are measured as an indicator of systemic inflammatory response. The primary objective of the study is to compare CRP levels between the two groups. Data are collected from medical records and laboratory examinations and analyzed to evaluate differences in inflammatory response between patients receiving dexmedetomidine and those not receiving dexmedetomidine.
