【摘要】 用生理多导仪分别记录麻醉状态下正常犬脑脊液压力(CSFP)和麻醉状态下蛛网膜下腔注射造影剂时CSFP、呼吸和心跳的动态变化。发现CSFP受呼吸影响较大,一呼一吸为CSFP波的1个周期。其次,心跳也对波形产生影响。比较2种条件下的CSFP波,发现蛛网膜下腔注射造影剂可引起CSFP显著升高,且变化幅度显著增大。更多还原

【Abstract】 Cerebrospinal fluid pressure (CSFP), respiration and palpitation of ten healthy miniature dogs respectively recorded on the condition of anesthesia and injecting contrast media (OMNIPAQUE(r) iohexol, 300 mg I/mL) into subarachnoid space. CSFP variations were according to respiration and palpitation. In addition, it was primarily affected by respiration, and take on a cycle in one respiration. CSFP was remarkably improved during injecting contrast media into subarachnoid space, and the range of CSFP variations were enlarged.更多还原
