We have examined the effect of EMLA on tourniquet pain and compared it with those of subcutaneous ring anaesthesia (SRA), a double cuff technique and a single cuff (control) during i.v. regional anaesthesia. The durations of analgesia (mean 57.3 (SD 16.6) min) and tolerance (72.3 (13.9) min) to tourniquet inflation in the EMLA group were comparable to those in the SRA group (54.1 (16.2) min and 68.3 (19.0) min), but significantly (P < 0.05) greater than those in the control group (30.0 (10.7) min and 45.6 (14.0) min). The double cuff technique was the most effective method, with 91.5 (14.9) min duration of analgesia. We conclude that EMLA provided a significant analgesic effect on tourniquet pain compared with the control group, but a relatively limited analgesic effect compared with a double cuff technique.
我们研究了EMLA对止血带疼痛的影响，并在静脉区域麻醉期间将其与皮下环形麻醉（SRA）、双袖带技术和单袖带（对照）的效果进行了比较。EMLA组对止血带充气的镇痛持续时间（平均57.3（标准差16.6）分钟）和耐受时间（72.3（13.9）分钟）与SRA组（54.1（16.2）分钟和68.3（19.0）分钟）相当，但显著（P<0.05）长于对照组（30.0（10.7）分钟和45.6（14.0）分钟）。双袖带技术是最有效的方法，镇痛持续时间为91.5（14.9）分钟。我们得出结论，与对照组相比，EMLA对止血带疼痛有显著的镇痛作用，但与双袖带技术相比，镇痛作用相对有限。
