摘要:
【摘要】目的通过超声测量眼球后3 mm处视神经鞘直径(optic nerve sheath diameter,ONSD)与眼球横径(ereball transverse diameter,ETD)的比值,评估右美托咪定对全身麻醉颅内动脉瘤栓塞术后拔管期颅内压的影响。方法选取宁波大学附属李惠利医院2023年5月至2023年11月拟行全麻颅内动脉瘤栓塞术患者40例,采用随机数字表法分为对照组(C组)和右美托咪定组(D组),每组20例。两组患者均采用标准化麻醉策略,D组于手术开始前以1 μg/(kg·h)泵注负荷剂量右美托咪定,泵注10 min。术中继续以0.5 μg/(kg·h)速率泵注,手术结束前0.5 h停止泵注。C组采用相同麻醉策略,不作特殊处理。在唤醒前(T0)、拔管即刻(T1)、拔管后5 min(T2)、拔管后10 min(T3)、拔管后15 min(T4)不同时间点,用经眶超声测眼球后3 mm处视ONSD及ETD,计算ONSD/ETD比值,评估颅内压的情况。同时记录两组拔管时的平均动脉压(MAP)、心率(HR)、血氧饱和度(SPO2)、咳嗽程度、拔管时间。结果与T0时点相比,两组患者在T1、T2时间点ONSD/ETD均增高(P<0.05)。其他时间点与T0时点比差异无统计学意义(P>0.05)。与C组比较,D组患者在T1、T2时间点ONSD/ETD更小,差异有统计学意义(P<0.05)。D组中重度咳嗽发生率低于C组(P<0.05)。与C组比较,D组拔管时HR、MAP降低(P<0.05)。D组拔管时间长于C组,差异有统计学意义(P<0.05)。结论基于超声测量ONSD/ETD比值,可较直观地反映拔管期颅内压的变化。右美托咪定通过有效抑制气管拔管时咳嗽反射和循环波动,进而减小气管拔管时颅内压的升高;但右美托咪定可能增加心动过缓、拔管延迟等事件发生。
