Effects of Full Inhalation of Sevoflurane and Total Intravenous Anesthesia on Hemodynamics, Serum Myocardial Enzymes, and Myocardial Markers in Elderly Patients Undergoing Hysterectomy

Abstract

Objective. To compare the effects of sevoflurane inhalation and intravenous anesthesia on hemodynamics, serum myocardial enzymes, and myocardial markers in elderly patients undergoing hysterectomy. Methods. Group A and group B were established randomly regarding a total of 126 elderly patients who underwent an elective hysterectomy. Patients in group A were given full anesthesia with sevoflurane, and patients in group B were given anesthesia with intravenous anesthesia. The operation time, anesthesia time, and recovery time in Postanesthesia Care Unit (PACU) were compared; plasma cortisol concentration, hemodynamics, serum myocardial enzymes, and myocardial markers were detected and compared between the two groups of patients before anesthesia ( $T_0$ ), after anesthesia ( $T_1$ ), and after surgery ( $T_2$ ). Results. Group A observed a longer extubation time and recovery time in PACU than group B ( $P<0.05$ ). Results show a lower systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and plasma cortisol concentration of $T_1$ by comparison with those of $T_0$ ( $P<0.05$ ), but no significant difference remains in terms of intergroup SBP, DBP, and HR ( $P>0.05$ ), and there was no interaction effect of groups and time ( $P>0.05$ ). The two groups showed no great disparity in the levels of lactate dehydrogenase (LDH), aspartate transaminase (AST), creatine kinase (CK), and CK-MB as a subtype of CK before surgery between the two groups of patients ( $P>0.05$ ). After surgery, LDH, AST, CK, and CK-MB levels in both groups were witnessed a surge, in which group A obtained higher levels of LDH, AST, CK, and CK-MB (all $P<0.05$ ). Conclusion. Total intravenous anesthesia will not increase the hemodynamic fluctuation of elderly patients undergoing hysterectomy and can reduce the damage to the myocardium of patients with surgical trauma, which can protect the myocardium of elderly patients to a certain extent, so it can be adopted as the optimal anesthesia protocol for surgery.
