To compare the effects of different anesthesia techniques on tourniquet-related ischemia-reperfusion by measuring the levels of malondialdehyde (MDA), ischemia-modified albumin (IMA) and neuromuscular side effects.
Sixty ASAI-II patients undergoing arthroscopic knee surgery were randomised to three groups. In Group S, intrathecal anesthesia was administered using levobupivacaine. Anesthesia was induced and maintained with sevoflurane in Group I and TIVA with propofol in Group T. Blood samples were obtained before the induction of anesthesia (t1), 30 min after tourniquet inflation (t2), immediately before (t3), and 5 min (t4), 15 min (t5), 30 min (t 6), 1 h (t7), 2 h (t8), and 6 h (t9) after tourniquet release.
MDA and IMA levels increased significantly compared with baseline values in Group S at t2-t 9 and t2-t7. MDA levels in Group T and Group I were significantly lower than those in Group S at t2-t8 and t2-t9. IMA levels in Group T were significantly lower than those in Group S at t2-t7. Postoperatively, a temporary 1/5 loss of strength in dorsiflexion of the ankle was observed in 3 patients in Group S and 1 in Group I.
TIVA with propofol can make a positive contribution in tourniquet-related ischemia-reperfusion.
通过测量丙二醛(MDA)、缺血修饰白蛋白(IMA)水平及神经肌肉副作用,比较不同麻醉技术对止血带相关缺血再灌注的影响。
60例拟行膝关节镜手术的ASA I-II级患者随机分为三组。S组采用左旋布比卡因行蛛网膜下腔麻醉。I组采用七氟醚诱导和维持麻醉,T组采用丙泊酚全凭静脉麻醉。于麻醉诱导前(t1)、止血带充气后30分钟(t2)、止血带松开前即刻(t3)以及止血带松开后5分钟(t4)、15分钟(t5)、30分钟(t6)、1小时(t7)、2小时(t8)和6小时(t9)采集血样。
S组在t2-t9和t2-t7时MDA和IMA水平较基线值显著升高。T组和I组在t2-t8和t2-t9时MDA水平显著低于S组。T组在t2-t7时IMA水平显著低于S组。术后,S组有3例患者、I组有1例患者出现踝关节背屈肌力暂时减弱1/5。
丙泊酚全凭静脉麻醉对止血带相关缺血再灌注有积极作用。
