Official title: Comparison of the Effects of Dexmedetomidine and Ketamine Infusion on the Inflammatory Response in Liver Resection: A Randomized Double-blind Placebo Study

Status Not yet recruiting

Clinical Trial Summary

Resection is being performed with increasing frequency in the treatment of surgical diseases of the liver. Ischemia-reperfusion injury is a major cause of liver injury occurring during surgical procedures, including hepatic resection and liver transplantation. Dexmedetomidine and ketamine, which are frequently used in anesthesia practice, also have strong anti-inflammatory capacity. The primary aim of this study is to investigate the effect of iv low-dose ketamine and dexmedetomidine infusion on inflammation in liver resection surgery, and the secondary aim is to determine its effect on pain scores.

Clinical Trial Description

General anesthesia will apply to all patients. Group 1 (Control Group, n=15); After intubation, saline infusion will be started. The control group will also be infused with the same volume of saline.

Group 2 (Ketamine Group, n=15); After intubation, the patient will be started on ketamine infusion at a low dose of 0.25mg/kg/hour.

Group 3 (Dexmedetomidine Group, n=15); After intubation, the patient will be infused at a low dose of 1 mg/kg for the first 10 minutes, then 0.5 mg/kg/hour.

For biochemical examination, blood will be taken for PEDF (Pigment epithelium-derived factor), Pentraxin 3, Serum amyloid A at the 1st and 12th postoperative hour. AST, ALT, GGT, LDH, bilirubin, CRP and hemogram results, which are routinely checked during these hours, will be recorded.

All the patients were administered 1000 mg iv paracetamol 30 minutes before the surgery ended, and was repeated every 6 hours following the surgery.The postoperative analgesia was evaluated by using VAS(Visual Analogue Scale).The PCA (Patient Controlled Analgesia) device was programmed at 10 μcq concentration with loading dose 50 μcq, 15-minute lock time, 25 μcq bolus without basal infusion, and this was continued for 24 hours in the postoperative recovery room. ;
