超声引导穿刺是一种新的麻醉技术。然而，为了学习目的，这些技术的训练需要尽可能接近现实生活的条件。有几个模型是可用的，但没有一个能将真实的解剖结构和筋膜通道的逼真感觉联系起来。我们研究的目的是比较新鲜的尸体和蒂尔的防腐尸体在超声引导下的穿刺。方法对8具新鲜尸体和8具Thiel’s防腐尸体进行调查。用超声探头扫描颈椎区域。记录年龄、性别和身体质量指数（BMI）。包括胸锁乳突肌（SCM）、前斜角肌和中斜角肌、甲状腺、神经和针在内的结构的可见度评价为0（不可见或能见度差）或1（能见度好）。通过筋膜的感觉（“砰”的一声）记为0（没有感觉到）或1（感觉到）。针刺神经移位的可能性、神经内注射的难度、神经穿透和神经肿胀的可能性均记录为0（不可能）或1（可能）。结果两组在性别、年龄和BMI方面具有可比性。Thiel组SCM肌和针的可见性较好。此外，“砰”的感觉和神经肿胀明显更频繁地出现在Thiel组。两组之间的其他结果没有显著差异。结论采用Thiel方法进行防腐处理的尸体可作为超声引导下穿刺的逼真模型。
Introduction Ultrasound-guided punctures are a new technique in anesthesia. However, training in these techniques requires conditions resembling real life as far as possible for learning purposes. Several models are available, but none associates realistic anatomy and lifelike sensations of the passage of fascias. The aim of our study was to compare fresh and Thiel's embalmed cadavers for ultrasound-guided punctures.Methods Eight fresh cadavers and eight Thiel's embalmed cadavers were investigated. The cervical region was scanned with an ultrasound probe. Age, sex and body mass index (BMI) were recorded. Visibility of he structures, including sternocleidomastoid (SCM) muscle, anterior and middle scalene muscles, thyroid gland, nerve and the needle, was evaluated as 0 (not visible or bad visibility) or 1 (good visibility). The feeling ("pop") of passing the fascias was noted as 0 (not felt) or 1 (felt). The possibility of nerve displacement with the needle, the difficulty of intraneural injection and the possibility of nerve penetration and nerve swelling were all recorded as 0 (not possible) or 1 (possible).Results The two groups were comparable in terms of sex, age and BMI. Visibility of the SCM muscle and the needle was better in the Thiel group. Moreover, the "pop" feeling and nerve swelling were significantly more frequently present in the Thiel group. There was no significant difference in terms of the other results between the two groups.Conclusions Cadavers embalmed according to Thiel's method should be recommended for ultrasound-guided punctures as a realistic and lifelike model.
