NCT03585647

Brief Summary

The study will analyze differentially regulated genes involved in oxidative stress and toxicology in peripheral blood mononuclear cells (PBMCs) of patients who underwent arthroplasty under three different anesthetic methods. The investigator hypothesized that anesthesia procedures trigger toxicity, thus inducing changes in the messenger ribonucleic acid (mRNA) profile. The results may provide a more profound understanding of the molecular mechanism of anesthesia and in overcoming the adverse effects arising from their use.

Outcome Measures

Primary Outcomes (1)

  • Changes of Gene expression profile from baseline at time points

    Effect of anesthesia techniques on the expression of genes indicative of stress and toxicity

    Gene expression will be evaluated in PBMCs at baseline (T0), up-30 min after surgery (T1) and on the third day (T2) after surgery.

Secondary Outcomes (1)

  • Relationship between deregulated genes and hepatic/renal cytotoxicity from baseline at time points

    Biochemical analysis have been evaluated in blood collected at baseline (T0), up-30 min after surgery (T1) and on the third day (T2) after surgery.

Study Arms (3)

GA-group

Patients undergoing elective hip arthroplasty included in the GA-group received general anesthesia. GA was induced by intravenous fentanyl (1 mcg/kg) and propofol (2 mg/kg), followed by vecuronium bromide (0.1 mg/kg) to facilitate tracheal intubation, then GA was maintained using a 50% air/oxygen mixture and sevoflurane.The end-tidal concentration of sevoflurane was adjusted to maintain heart rate and blood pressure values within 20% of baseline. Mechanical ventilation was regulated to maintain the end-tidal carbon dioxide partial pressure ranging between 4.3 and 5.1 kilopascal.

Procedure: hip arthroplasty

RA-group

Patients undergoing elective hip arthroplasty included in the RA-group received regional anesthesia. Regional anaesthesia included continuous lumbar plexus block, performed by or under supervision of an experienced operator using a nerve stimulator (Stimulax, B. Braun) and Continued Peripheral Nerve Block Set. A total dose of 20 ml of 0.5% Levobupivacaine was administered at the time of catheter placement. Dural puncture was performed at the L3-L4 interspace using a 25-Gauge whitaker spinal needle (Becton-Dickinson, New Jersey, USA) with the midline approach using 3 ml of 0.5% Levobupivacaine.

Procedure: hip arthroplasty

IA-group

Patients undergoing elective hip arthroplasty included in the IA-group received integrated anesthesia. The patients received regional anaesthesia (lumbar plexus block + spinal anaesthesia) as described protocol. General anaesthesia was induced by propofol 1% and a laryngeal mask airway of appropriate size was inserted. General anaesthesia and mechanical ventilation were maintained as standard protocol.

Procedure: hip arthroplasty

Interventions

Hip replacement is a surgery for people with severe hip damage. The most common cause of damage is osteoarthritis.

Biospecimen

Retention: SAMPLES WITH DNA

Whole blood samples will be obtained from all enrolled patients. The samples will be collected in heparin tubes and peripheral blood mononuclear cell (PBMC) fraction will be isolated for total RNA extraction.
