Abstract:
Objective To investigate the effect of different sedation depth of anesthesia the BIS settings (BISis 45 and 55) to perioperative hemodynamic. Methods Thirty-two patients were randomly divided into two groups. Through closed-loop target controlled infusion technology, depth of sedation anesthesia in A:the BIS=45, and in B: the BIS=55.12 time points(i.e. before operation, tracheal intubation instant, operation beginning, 20, 40,60,80,100 and 120 minutes after operation beginning, operation accomplishment point, tracheal catheter pulling out point, before patient′s carried out of operation room)perioperativenoninvasivemean arterial blood pressureandheart rate wererecorded. Results Themean arterial blood pressurebetween the two groups at time point T2,T11 was significantly different. Within group B,compared with T1, there wassignificantdifferenceat T2,T11. Heart ratein group B at T5and T10increasedsignificantly compared with A.Within group B,heart rate at T5,T6 increased significantly compared with that at T1. Conclusion Compared with BIS 55, the sedation anesthesia depth of BIS 45 can better keep stable of blood pressureandheart rate.
