In the past it was taught that local anesthetic should not be used with adrenaline for procedures in the extremities. This dogma is transmitted from generation to generation. Its truth has not been questioned, nor the source of the doubt. In many situations the benefit of use was not understood, because it was often thought that it was not necessary to prolong the anesthetic effect, since the procedures were mostly of short duration. After the disclosure of studies of Canadian surgeons, came to understand that the benefits went beyond the time of anesthesia. The WALANT technique allows a surgical field without bleeding, possibility of information exchange with the patient during the procedure, reduction of waste material, reduction of costs, and improvement of safety. Thus, after passing through the initial phase of the doubts in the use of this technique, the authors verified its benefits and the patients' satisfaction in being able to immediately return home after the procedures.
过去人们认为,在四肢手术中局部麻醉不应与肾上腺素一起使用。这条教条代代相传。其真实性从未受到质疑,质疑的源头也未被探究。在许多情况下,使用肾上腺素的益处未被理解,因为人们通常认为没有必要延长麻醉效果,毕竟手术大多持续时间较短。在加拿大外科医生的研究成果公布后,人们才明白其益处不止于麻醉时长。清醒局部麻醉技术能实现无出血的手术视野,术中可与患者交流信息,减少耗材,降低成本,并提高安全性。因此,在经历了对该技术使用的最初疑虑阶段后,作者证实了其益处以及患者对术后能立即回家的满意度。
