Effects of dexmedetomidine anesthesia on surgery condition, RAAS activity and renal function in laparotomy / 中国生化药物杂志

ABSTRACT

Objective To study the effect of dexmedetomidine anesthesia on surgery condition, renin-angiotensin-aldosterone system (RAAS) activity and renal function of laparotomy patients.Methods 96 patients received laparotomy in our hospital during May 2012 to October 2015 were studied, which were divided into dexmedetomidine group (D group) and control group (C Group) by random number table method and received different anesthetic regimes.Then surgery condition, renal function indexes and plasma renin, angiotensin II levels of two groups were compared.Results The operation time, intraoperative blood loss, intraoperative transfusion volume and awakening time of D group and C group had no significant difference.10 min after opening abdomen and 10 min before closing abdomen, the plasma renin, angiotensin II, cystatin C (Cys-C),α1-microglobulin (α1-MG) contents were significantly lower than those of C group(P<0.05).Conclusion Dexmedetomidine anesthesia applicated in laparotomy could inhibit the RAAS activity, protect renal function, and its anesthesia effect is more precise.
