ABSTRACT

Objective:

To evaluate the effect of donor dexmedetomidine preconditioning on the renal function of patients undergoing living-related kidney transplantation.

Methods:

Sixty American Society of Anesthesiologists physical status Ⅲ-Ⅳ patients, regardless of gender, aged 20-64 yr, with body mass of 18.5-28.0 kg/m 2, undergoing living-related kidney transplantation, were selected.Sixty corresponding donors, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, regardless of gender, aged 20-64 yr, with body mass index of 18.5-28.0 kg/m 2, were selected.The patients and donors were divided into 2 groups using a random number table

method:

control group (group C) and dexmedetomidine group (group D), with 30 pairs in each group.Before induction of anesthesia, dexmedetomidine was intravenously infused over 10 min in a loading dose of 1 μg/kg followed by an intravenous infusion of 0.5 μg·kg -1·h -1 until the time point when the renal artery was blocked immediately in the donors of group D, while the equal volume of normal saline was given instead until the time point when the renal artery was blocked immediately in the donors of group C. In both groups, total intravenous anesthesia was applied in donors and recipients, Nacotrend values were maintained at 40-60 during operation, mean arterial pressure and heart rate were maintained within the normal range, and dopamine was intravenously infused when necessary.The warm ischemia time and cold ischemia time of donor kidneys were recorded in the two groups.Peripheral venous blood samples were collected from the donors immediately before renal artery occlusion and from the recipients before renal artery opening (T 0) and at 1, 12 and 24 h after renal artery opening (T 1-3) to determine the serum creatinine (Cr), urea nitrogen (BUN) and cysteine protease inhibitor C (CysC) concentrations.The intraoperative volume of fluid infused, urine volume and consumption of propofol, remifentanil and dopamine were recorded in the receptors of two groups.

Results:

There was no significant difference in the concentrations of Cr, BUN and CysC and warm ischemia time and cold ischemia time of kidneys in between the two groups of donors ( P>0.05). There was no significant difference in the consumption of propofol, remifentanil and dopamine, volume of fluid infused and urine volume during surgery between the two groups of recipients ( P>0.05). Compared with group C, the concentrations of Cr, BUN and CysC were significantly decreased in at T 1 in group D ( P<0.05).

Conclusion:

Donor dexmedetomidine preconditioning is helpful in improving the perioperative renal function of patients undergoing living-related kidney transplantation.
