Monitoring The Peripheral Hemodynamics In Patients With Craniocerebral Operation Under General Anesthesia By Color Doppler Ultrasound

Objective: To explore the clinical significance of monitoring the femoral artery hemodynamics of cerebral hemorrhage patients under general anesthesia by color doppler ultrasound.Methods: Totally 30 patients who received emergency craniotomy for intracranial hematoma were performed the induction of general anesthesia and endotracheal intubation. The changes of femoral artery peak systolic velocity(PSV), early diastolic reverse peak velocity(DRPV), systolic diameter(Ds), diastolic diameter(Dd), systolic blood pressure(SBP), diastolic blood pressure(DBP), mean arterial pressure(MAP) and heart rate(HR) at each time point of before and after anesthesia induction, intubation,removal of bone flap, cutting the endocranium were observed and recorded. Analyze the correlation between BP and DRPV, BP and PSV, HR and PSV, DRPV and PSV.Results: Compared with those before anesthesia induction, the SBP, DBP, MAP, DRPV and PSV were decreased(P<0.05), Ds and Dd increased(P<0.05) at each time point.Compared with those after anesthesia induction, SBP, DBP, MAP increased, PSV reduced,DRPV increased(P<0.05) at the intubation moment., the change of Ds and Dd was not statistically significant, which compared with those remove the bone flap, SBP, DBP,MAP decreased, PSV and DRPV decreased, Ds and Dd have no statistic difference. The changes of HR at each time point was not statistically significant(P > 0.05). SBP and DBP were positively correlated with DRPV(P<0.05), SBP and DBP were negatively correlated with PSV(P<0.05), there was no significant correlation between HR and PSV,PSV and DRPV(P > 0.05).Conclusion: BP was positively correlated with DRPV, BP was negatively correlated with PSV. Color Doppler ultrasound could reflect the femoral artery hemodynamics of patients who subjected to craniotomy for intracranial hematoma under general anesthesia, which helpful to the general anesthesia strategies.
