摘要
We evaluated the effect of continuous perfusion of esmolol on cardiovascular risk during curative laparoscopic surgery for gastrointestinal cancer in elderly patients. Sixty patients with gastrointestinal cancer, aged from 60 to 80 years, were divided into an esmolol group (ES, n = 30) and a control group (NS, n = 30). ES patients were treated with esmolol at a dose of 0.3 mg/kg 3 min before tracheal intubation, and received continuous perfusion of esmolol at a dose of 50 mu g/kg/min during operation. In NS, esmolol was replaced by saline. SBP/DBP, MAP, HR, SPO2, PETCO2, the depth of anesthesia and the value of RPP were recorded before anesthesia (To), during intubation (T-1), 10 min before pneumoperitoneum (T-2), during pneumoperitoneum (T-3), 30 min after incision (T-4), at the end of surgery (T-5), during extubation (T-6) and 30 min after extubation (T-7). The serum levels of cTnI, CK, CK-MB and LDH were measured before anesthesia, 6 and 30 h after surgery. HR, MAP, RPP at T-1, T-3, T-6, in ES were obviously decreased compared with NS (P < 0.05). There were no significant differences between both groups at different time points with respects to the serum levels of cTnI, CK, CK-MB and LDH. No major adverse cardiocerebral event was observed in both groups in three postoperative months. The present study indicated that the application of esmolol during curative laparoscopic surgery for gastrointestinal cancer can effectively reduce the cardiovascular responses in intubation, operation and extubation, sustain hemodynamic stable, reduce myocardial oxygen consumption, and prevent perioperative adverse cardiovascular events, but had no significant myocardial protective effect.
