40例后颅凹手术病例实行以收缩压(SAP)为警报监测脑干功能;随机分保留自主呼吸组和控制呼吸组,每组20例。术中用PROPAG106EL生命监测仪连续监测血压,并在分离和摘除肿瘤时以读SAP改变,界定30mmHg为警界值而停缓手术操作。保留自主呼吸组同时观察呼吸方式改变并寻找与SAP改变对应值。结果控制呼吸组在分离和摘除肿瘤时发生SAP升高13例,保留自主呼吸组15例。15例中呼吸方式改变7例,其SAP对应值平均为24mmHg,出现时间较SAP是晚。显示在后颅凹术中以SAP为警报监测脑干功能较保留自主呼吸、以呼吸方式为警报更敏感,更可靠。
In 40 cases of posterior fossa surgery, systolic blood pressure (SAP) was used as an alarm to monitor brainstem function. The spontaneous breathing group and control breathing group were randomly divided into two groups, 20 cases in each group. Intraoperative use of PROPAG106EL life monitor continuous monitoring of blood pressure, and in the separation and removal of the tumor to read SAP change, defined 30mmHg as the police value and halt the operation. Retained spontaneous breathing group while observing changes in breathing patterns and looking to change the corresponding value with SAP. Results In control group, 13 cases of SAP increased and 13 cases of spontaneous breathing group remained in control group. Among the 15 cases, 7 cases changed their breathing pattern, the average value of SAP was 24mmHg, and the appearance time was later than that of SAP. It is shown that monitoring brainstem function with SAP as an alarm in posterior cranial recess resembles spontaneous respiration, and is more sensitive and reliable in respiration for alerting.
