Effect of Total Intravenous Anesthesia vs Inhalational Anesthesia on the Level of Inflammatory Markers
Sponsor: Ain Shams University
Summary
This study aims to compare the effects of total intravenous anesthesia (TIVA) vs inhalational anesthesia on postoperative levels of inflammatory markers, length of hospital stay, and the incidence of postoperative nausea and vomiting in patients undergoing inguinal hernia repair. Number participants: Participants will be divided into 2 groups with sample size of at least 20 patients per group. Plan of the work: All patients will receive general anesthesia according to Ain Shams hospital protocol which follows the standards of the American Society of Anesthesiologists. Group A will be TIVA group and Group B will be Sevoflurane group. Sample Collection and Laboratory Analysis: Venous blood samples will be collected from each patient at three time points: preoperative (baseline, sample 0), 6 hours postoperative (sample 1), and 24 hours postoperative (sample 2).
Official title: Effect of Propofol and Dexmedetomidine-Based Total Intravenous Anesthesia Versus Sevoflurane-Based Inhalational Anesthesia on the Level of Inflammatory Markers in Patients Undergoing Inguinal Hernia Repair.

Interventions
Venous blood sampling preoperatively
5 mL of venous blood will be aseptically withdrawn into a sterile plain tube. Serum interleukin-6 (IL-6) levels will be measured using the enzyme-linked immunosorbent assay (ELISA) method. Ferritin and C-reactive protein (CRP) concentrations will be analyzed using a COBAS automated analyzer. Additionally, a 2 mL blood sample will be collected in an EDTA tube for complete blood count (CBC) analysis, which will be performed using the Sysmex Coulter hematology analyzer
Venous blood sampling at 6 hours postoperative
5 mL of venous blood will be aseptically withdrawn into a sterile plain tube. Serum interleukin-6 (IL-6) levels will be measured using the enzyme-linked immunosorbent assay (ELISA) method. Ferritin and C-reactive protein (CRP) concentrations will be analyzed using a COBAS automated analyzer. Additionally, a 2 mL blood sample will be collected in an EDTA tube for complete blood count (CBC) analysis, which will be performed using the Sysmex Coulter hematology analyzer
Venous blood sampling at 24 hours postoperative
5 mL of venous blood will be aseptically withdrawn into a sterile plain tube. Serum interleukin-6 (IL-6) levels will be measured using the enzyme-linked immunosorbent assay (ELISA) method. Ferritin and C-reactive protein (CRP) concentrations will be analyzed using a COBAS automated analyzer. Additionally, a 2 mL blood sample will be collected in an EDTA tube for complete blood count (CBC) analysis, which will be performed using the Sysmex Coulter hematology analyzer
Propofol
Group A (TIVA group): will receive 1 μg/kg IV dexmedetomidine over 10 min, 1 μg/kg IV fentanyl, 2 mg/kg IV propofol, and 0.5 mg/kg IV atracurium. Maintenance of anesthesia will be achieved by 0.5 μg/kg/h dexmedetomidine IV infusion and 6-12 mg/kg/h propofol IV infusion titrated according to bispectral index value (BIS) with target BIS 40-60.
Dexmedetomidine
Group A (TIVA group): will receive 1 μg/kg IV dexmedetomidine over 10 min, 1 μg/kg IV fentanyl, 2 mg/kg IV propofol, and 0.5 mg/kg IV atracurium. Maintenance of anesthesia will be achieved by 0.5 μg/kg/h dexmedetomidine IV infusion and 6-12 mg/kg/h propofol IV infusion titrated according to bispectral index value (BIS) with target BIS 40-60.
Sevoflurane
Group B (Sevoflurane group): will receive 1 μg/kg IV fentanyl, 8% sevoflurane via face mask and 0.5 mg/kg IV atracurium. Maintenance of anesthesia will be achieved with 2%-4% sevoflurane titrated according to BIS with target BIS 40-60
