磁共振(MRI)时如果躯体或肢体稍有活动,则检查的结果易出伪差,因此患中枢神经系疾病的小儿做MRI检查时,必需充分镇静,保持不动。 作者报道84例病儿(2周～11岁),均无呼吸问题也无肝肾功能异常和高颅压。全部病儿都不用术前药,入扫描室后,连续监测心电和心率,间断检查血压,其中38例还监测SpO_2。用输液泵静滴异丙酚,入睡后监测呼气末CO_2浓度(ETCO_2)和CO_2波形,保留自主
MRI (magnetic resonance) (MRI) if the body or limb slightly active, the test results prone to artifacts, so suffering from central nervous system diseases in children with MRI examination, you must be fully sedation, remain motionless. The authors reported 84 cases of sick children (2 weeks to 11 years old), no respiratory problems nor abnormal liver and kidney function and high intracranial pressure. All of the sick children did not need preoperative drugs, after entering the scanning room, continuous monitoring of ECG and heart rate, intermittent blood pressure examination, of which 38 cases were also monitored SpO_2. Propofol was infused intravenously by the infusion pump and the end-tidal CO 2 concentration (ETCO 2) and CO 2 waveform were monitored after falling asleep, leaving the autonomic
