采用1％Dicainae行食管电极周围粘膜麻醉,对20例在食管调搏术中有不同程度痛苦者进行用药后观察。用药后患者疼痛感减轻或消失。起搏阈值由25.2±7V降至19.4±6.4V(P<0.001)。而对心率、窦房传导时间、窦房结恢复时间、校正窦房结恢复时间、房室结功能不应期及有效不应期、左房有效不应期及相对不应期等电生理参数无明显影响(P>0.05)。笔者认为食管调搏术中应用粘膜麻醉可减少电刺激所致不良反应,有利于电极与食管壁接触,故而能降低起搏阈值,减轻病人痛苦。
Peri-mucosal anesthesia was performed on 1% Dicainae line of esophageal electrodes. Twenty patients with different degrees of pain during esophageal pacing were observed. Pain relief or disappearance of patients after treatment. Pacing threshold decreased from 25.2 ± 7 V to 19.4 ± 6.4 V (P <0.001). And heart rate, sinus node conduction time, sinus node recovery time, correction of sinus node recovery time, AV node function refractory period and effective refractory period, left atrial effective refractory period and relative refractory period and other electrophysiological parameters No significant effect (P> 0.05). I believe that the application of mucosal anesthesia in esophageal pacing can reduce the adverse reactions caused by electrical stimulation, is conducive to the electrode and the esophageal wall contact, it can reduce the pacing threshold, reduce patient pain.
