Pulsatile ocular blood flow, intraocular pressure, systemic blood pressure, and heart rate was measured in two groups of 15 patients. One received lignocaine 1.5 mg/kg intravenously prior to induction. There was a significant increase in intraocular pressure after suxamethonium, which was not associated with any rise in ocular blood flow. Both the IOP and ocular blood flow increased significantly after tracheal intubation. A rise in ocular blood flow reflects the stress response associated with intubation. Lignocaine failed to attenuate either response.
对两组各15名患者测量了搏动性眼血流量、眼压、全身血压和心率。一组在诱导前静脉注射1.5mg/kg利多卡因。琥珀胆碱注射后眼压显著升高,这与眼血流量的任何增加均无关。气管插管后眼压和眼血流量均显著增加。眼血流量的增加反映了与插管相关的应激反应。利多卡因未能减弱这两种反应。
