A recent study performed in this department showed that a subcutaneous injection of local anaesthetic was significantly less painful than the insertion of a 22-gauge venous cannula. However, our colleagues remained sceptical that local anaesthetic infiltration would eliminate the pain of cannulation. Consequently a further study was undertaken to compare the pain of cannulation with and without the use of local anaesthetic. The results show that pain of cannulation is significantly (p < 0.003) reduced after subcutaneous infiltration with 1% lignocaine when compared to cannulation without local infiltration. Persistent discomfort at the site of cannulation was eliminated by the use of local anaesthetic.
该科室最近进行的一项研究表明，皮下注射局部麻醉剂的疼痛程度明显低于插入22号静脉套管针。然而，我们的同事仍然怀疑局部麻醉剂浸润能否消除插管的疼痛。因此，我们又进行了一项研究，比较使用和不使用局部麻醉剂时插管的疼痛程度。结果显示，与未进行局部浸润的插管相比，用1%利多卡因进行皮下浸润后，插管疼痛程度显著降低（p < 0.003）。使用局部麻醉剂消除了插管部位的持续不适。
