The use of epinephrine-containing local anesthetic solutions in pre-eclampsia is controversial. While epinephrine in local anesthetic solutions has been used without complications in this setting, a hypertensive reaction remains a concern among many clinicians.
An epidural anesthetic containing epinephrine was administered to a hypertensive parturient for cesarean delivery. When a hypertensive crisis developed, the radial artery was cannulated and administration of sodium nitroprusside was initiated. Arterial blood samples were evaluated for plasma norepinephrine and serum lidocaine concentrations.
The introduction of lumbar epidural anesthesia for cesarean delivery using 30 mL 2% lidocaine with 1:200,000 epinephrine resulted in a profound hypertensive reaction, in the patient with pre-eclampsia, despite an adequate level of epidural anesthesia.
Epinephrine-containing local anesthetic solutions may place a hypertensive parturient at significant risk of an acute hypertensive reaction.
含肾上腺素的局部麻醉溶液用于子痫前期存在争议。虽然在此情况下局部麻醉溶液中的肾上腺素使用时未出现并发症,但许多临床医生仍担心会发生高血压反应。
对一名高血压产妇实施含肾上腺素的硬膜外麻醉以进行剖宫产。当发生高血压危象时,经皮穿刺桡动脉并开始输注硝普钠。评估动脉血样本中的血浆去甲肾上腺素和血清利多卡因浓度。
对于该子痫前期患者,使用30毫升含1:200,000肾上腺素的2%利多卡因进行剖宫产的腰段硬膜外麻醉,尽管硬膜外麻醉平面足够,但仍导致严重的高血压反应。
含肾上腺素的局部麻醉溶液可能使高血压产妇面临急性高血压反应的重大风险。
