Antibacterial activity of lidocaine in mixtures with Diprivan 总被引:1,自引:0,他引:1
Gajraj R. J.; Hodson M. J.; Gillespie J. A.; Kenny GNC.; Scott N. B. 《British journal of anaesthesia》1998,81(3):444-448
We have studied the antibacterial activity of different concentrations of
0.005-2% lidocaine (lignocaine) in mixtures with Diprivan (propofol),
against micro-organisms commonly implicated in sepsis as a result of
extrinsically contaminated Diprivan. Bacterial colony counts were reduced
progressively with increasing concentrations of lidocaine. Bacteriostatic
and bactericidal concentrations of lidocaine were 0.2- 2%. Lidocaine 2% was
not bactericidal for one of the seven organisms tested. By inhibiting
bacterial replication, lidocaine, when added to Diprivan to reduce pain on
injection, may possibly reduce the harmful consequences if extrinsic
contamination occurs.

Life-threatening anaphylactoid reactions to propofol (Diprivan) 总被引:6,自引:0,他引:6
Fourteen patients who had had a life-threatening reaction within a few minutes after receiving propofol (Diprivan) were investigated for anaphylaxis 4-6 weeks after the incident. Three kinds of immunologic tests were carried out: skin tests (prick tests and intradermal tests with the drugs used and Intralipid, the solvent for propofol), a leukocyte histamine release test, and a radioimmunoassay (RIA) of immunoglobulin E (IgE) against propofol and muscle relaxants, when they had been given with propofol. It had been previously shown that these were always negative in patients anesthetized with propofol without any complications. Thirteen of the 14 patients had at least one positive test supporting hypersensitivity to propofol; 2 patients had three tests positive; 4 had two tests positive; and 7 had one test positive. The skin tests with Intralipid were negative in 4 patients whose tests with propofol were positive. Two patients who had been given muscle relaxants at the same time as the propofol had positive IgE-RIA to both drugs. In one patient, results of all the tests remained negative, and the mechanism involved in the reaction remained unidentified. It is note-worthy that 9 patients of 14 had allergic histories that were known before the anesthetic (atopy; allergy to antibiotics, muscle relaxants, lidocaine, colloids) and that none of the patients had ever received propofol or Intralipid before. It is possible that the IgE that linked abnormally with the propofol had specific binding sites for the phenyl nucleus and the isopropyl groups, which are present in propofol and many other drugs.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

目的:探讨“异丙酚+芬太尼”用予气管拨管术减轻拨管对患者呼吸道,循环干扰的临床意义。方法:60例择期腹腔镜胆囊切除的患者随机分成两组,实验组在拔管前给予异丙酚0.5mg/kg,芬太尼0.75μg/kg静注;对照组按常规方法拨管,观察拨管前,吸引。拨管时及拨管后3、5、10分钟的血压,心率。结果:不同处理方法存在组间差别(P〈0.05),患者的收缩压,舒张压,心率在不同的处理方法下不同拔管时相蜜化的趋势不同(P〈0.01),其中实验组不同拨管时相收缩压,舒张压,心率均较为稳定。结论:在拔管期应甩适量异再酚和芬太尼对于呼吸道,心血管反应的抑制殛拨管期血流动力学的平稳有较好的作用。 相似文献

We report a case in which two fragments due to coring from the rubbercap of a 50 ml Diprivan vial were detected only immediately before infusion to a patient. The attending anesthesiologist noticed the foreign bodies by chance. The rubbercap was punctured only once, but the two foreign bodies from the syringe were proved to be from the rubbercap by infrared spectrometer analysis. It is difficult to recognize the small fragments in Diprivan which is white unclear emulsion. Therefore, anesthesiologists should be aware of the danger of coring. 相似文献
