Requirements on the production of illustrations, Patients are more prone to drop in blood pressure or severe circulatory depression. According to reports, quick ultra-short effect of intravenous narcotic analgesic drug remifentanil in the maintenance of anesthesia in elderly patients, we can maintain a stable circulation and myocardial protection]. In this study, the drug inhalation anesthetics nitrous oxide and epidural block combined with anesthesia compared with the control group, reduce the amount of epidural local anesthetic injection, clinical observations indicate that the drop in blood pressure after anesthesia cases than Y group less. Y-group of patients the operative time is longer than the R group, but the two groups of patients after surgery to wake extubation time was similar, may be two groups of patients were not applied long-term narcotic drug-related. Table I Comparison of two groups of patients with general information (n = 20, X ± S) and the R group, P 0.05). Y group the SBP of DBP induction of anesthesia before surgery were lower than before anesthesia <0.01), P is slower than before anesthesia (P <0.05). Y group SBP, DBP at T2, T3 compared with R group (P <0.01). Surgery after induction of anesthesia to surgery before the start of vasoactive drugs to enhance the R group of blood pressure by 7 cases of Y group of 11 cases. Total R group (9 ± 5) mL of Y- group (17 ± 5) mL of, Y, epidural injection epidural injection total is greater than the R group (P <0.01). The two groups of patients were followed up for no cases of intraoperative awareness. This study suggests that remifentanil nitrous oxide combined with epidural anesthesia used in the elderly abdominal surgery, surgery in circulation compared with the stability of the nitrous oxide combined with epidural anesthesia group, for anesthesia in abdominal surgery on the elderly.
