Effects of Different Anesthetics on Perioperative Organ Protection and Postoperative Cognitive Function in Patients Undergoing Cardiac Valve Replacement with Cardiopulmonary Bypass

An observational study on the application of fast-track cardiac anesthesia using target-controlled infusion of sufentanil and propofol in valve replacement surgery

The aim of this study was to evaluate the efficacy of fast-track cardiac anesthesia using target-controlled infusion of sufentanil and propofol in valve replacement surgery. The clinical data of 88 patients with rheumatic heart disease undergoing valve replacement surgery were retrospectively analyzed and grouped based on different treatment methods. Among them, 44 cases received fast-track cardiac anesthesia using target-controlled infusion of fentanyl and propofol from November 2019 to July 2021 were set as the control group, and 44 cases received fast-track cardiac anesthesia using target-controlled infusion of sufentanil and propofol from August 2021 to February 2022 were set as the study group. The study group showed shorter postoperative awakening time, extubation time, and hospital stay duration, and lower dosage of dopamine and nitroglycerin consumption compared to the control group (P < .05). At T5 and T6, both groups exhibited higher ACTH, cortisol (Cor), and C3a than at T0, and the study group showed significantly lower ACTH, Cor, and C3a at T5 and T6 than the control group (P < .05). At T7, the control group showed higher ACTH, Cor, and C3a than at T0, and ACTH, Cor, and C3a were significantly lower in the study group than in the control group at T7 (P < .05). Fast-track cardiac anesthesia using target-controlled infusion of sufentanil and propofol in valve replacement surgery has demonstrated favorable application effects, which stabilizes hemodynamics, alleviates myocardial damage, suppresses endocrine stress responses, and does not increase adverse reactions, thereby exhibiting good safety.

Efficacy of Sevoflurane and Propofol Anesthesia on Perioperative Adverse Cardiovascular Events and Hemodynamics in Elderly Patients With Diabetes

PURPOSE

This study was undertaken to compare the effects of sevoflurane and propofol anesthesia on perioperative hemodynamics and perioperative adverse cardiovascular events (PACE) in elderly patients with diabetes undergoing general anesthesia for noncardiac surgery.

METHODS

According to the random number table (n = 40), 80 patients with diabetes undergoing noncardiac general anesthesia were divided into a control group and an observation group. In the control group, the patients were given propofol 4 to 6 mg/(kg·h), continuously pumped to maintain anesthesia. In the observation group, the patients were given maintained concentration of sevoflurane for 1 to 1.5 minimum alveolar concentration (MAC) for continuous inhalation, while remifentanil with volume fraction of 0.05 to 1 µg/(kg·min) was given for continuous pumping in both groups. The heart rate (HR) and mean arterial pressure (MAP) of the patients were recorded, and the serum creatine kinase-MB (CK-MB) and cardiac troponin I (cTnI) contents before anesthesia (T0), immediately after surgery (T3), and 24 hours later (T4) as well as the blood glucose levels at T0 and T3 were compared between the two groups. The occurrence of PACE in the two groups was compared during the perioperative period.

FINDINGS

The HR and MAP 5 minutes after intubation (T1), 1 hour after skin incision (T2), and at T3 in the two groups were significantly lower than those of T0 (P < 0.05), whereas the MAP and HR of T1, T2, and T3 in the observation group were significantly higher than those of the control group (P < 0.05). The T3 blood glucose levels were significantly higher in the two groups than that in T0 (P < 0.05), and the T3 blood glucose levels in the observation group were significantly lower than that in the control group (P < 0.05). CK-MB and cTnI in the two groups were significantly higher at T3 and T4 than T0 (P < 0.05), whereas CK-MB and cTnI in the observation group were significantly lower than in the control group at T3 and T4 (P < 0.05). The incidence of hypotension and PACE was significantly lower in the observation group than in the control group (P < 0.05).

IMPLICATIONS

Compared with propofol IV general anesthesia, sevoflurane inhalation anesthesia can improve perioperative hemodynamics stability and reduce the incidence of PACE in elderly patients with diabetes undergoing noncardiac surgery.
