Methylprednisolone Combined Electric-acupuncture on Cognitive Function

Study Overview
=================
Brief Summary
-----------------
Postoperative cognitive dysfunction (POCD) refers to the patients in the central nervous system complications after general anesthesia and clinical manifestations of mental disorder, anxiety, personality changes, impaired memory, personality, social skills and cognitive function after surgery for this decline is called postoperative cognitive dysfunction.Due to the lack of effective clinical treatments, how to prevent and solve the postoperative cognitive dysfunction has become a difficulty and a focus of research in the field of anesthesia.Methylprednisolone is a new type of cortical hormone, because of its strong anti-inflammatory effect, less adverse reactions, is widely used in clinical anesthesia.Electric acupuncture as a kind of traditional treatments, after years of clinical application and achieved good curative effect in practice.In this paper by comparing brain oxygen saturation, blood biochemical indexes, Montreal cognitive assessment scale (MOCA) on cognitive function in patients with grade indexes, such as observation of methylprednisolone combined electric acupuncture treatment of elderly patients with general anesthesia early after the operation, the influence of cognitive function. Through comparing the operation of cerebral oxygen saturation, blood biochemical indexes, Montreal cognitive assessment scale (MOCA) on cognitive function in patients with grade indexes, such as observation of methylprednisolone combined electric acupuncture treatment of elderly patients with general anesthesia early after the operation, the influence of cognitive function.

Detailed Description
-----------------
Choose descending colon cancer radical general anesthesia, 80 cases of patients, ASA Ⅱ   level III, aged 65   75, were randomly divided into two groups: anesthesia method selects the tracheal intubation general anesthesia.All Diprifusor propofol used in patients with TCI system, with the initial plasma concentration of 2.0 ug/ml start TCI, and intravenous sufentanil injection 0.15 ug/kg, propofol 1 ug/ml every 1 minute.After the BIS value < 75, start the fentanyl TCI system, maintaining the plasma concentrations of 4 ng/ml, vein to the interaction between rocuronium 0.8 mg/kg, insert the endotracheal intubation after mechanical ventilation.Adjust the propofol infusion control electrical double-frequency index between 45 to 55.The experimental group to give intravenous methylprednisolone 1 mg/kg/sack.And 1 mg/kg * d continuous application to the third day after surgery. 1 day before the surgery, postoperative 1 day, 2 days, 3 days, 7 days the MOCA scale to assess cognitive function after surgery for the patient.(T0) prior to the induction and bi (T1), 24 h after surgery (T2) and 48 h after surgery (T3) extraction in patients with venous blood, adopts the method of enzyme-linked immunosorbent (ELISA) determination of serum IL - 1 beta, IL - 6, Aβ1-42, p- Tau concentration.In rSO2 intraoperative continuous monitoring, and calculate the average rSO2, intraoperative rSO2 down the biggest percentage compared with basic value rSO2 % of Max.And record the occurrence of adverse reactions to special circumstances.
