Intraosseous (IO) anaesthesia has been shown to be effective in children. However, the pain associated with anaesthetic injections, and its acceptance by children, have never been studied.
The aim of this study was to assess the pain associated with the IO injection of 4% articaine with 1 : 200 000 epinephrine using the computerized QuickSleeper' system in a population of children and adolescents.
IO anaesthesia was performed on patients aged 10.4 +/- 2.6 years of age. The patients assessed their pain on a faces pain scale (FPS) and on a visual analogue scale (VAS). The operators were also asked to assess signs of patient pain/discomfort.
No pain or mild discomfort was reported by, respectively, 81.8% (FPS) and 83.9% (VAS) of the patients. Some 58.9% of children with previous experience of dental anaesthesia reported that computerized IO anaesthesia was more comfortable than traditional infiltration methods. Operators noted signs of discomfort during penetration and injection in 18.3% and 25.3% of the patients, respectively.
This study showed that the majority of children reported no pain or mild pain when anaesthetic was administered by computerized needle rotation and solution deposition. This technique holds promise for use by trained paediatric dentists.
骨内（IO）麻醉已被证明对儿童有效。然而，与麻醉注射相关的疼痛及其在儿童中的接受程度从未被研究过。
本研究的目的是使用计算机化的“QuickSleeper”系统，评估在儿童和青少年群体中，骨内注射含1:200 000肾上腺素的4%阿替卡因时的疼痛情况。
对年龄为10.4±2.6岁的患者进行骨内麻醉。患者通过面部疼痛量表（FPS）和视觉模拟量表（VAS）评估疼痛程度。同时，操作人员也被要求评估患者疼痛/不适的体征。
分别有81.8%（FPS）和83.9%（VAS）的患者报告无疼痛或轻度不适。约58.9%有过牙科麻醉经历的儿童表示，计算机化骨内麻醉比传统浸润麻醉方法更舒适。操作人员分别在18.3%和25.3%的患者穿刺和注射过程中注意到不适体征。
本研究表明，当通过计算机化的针旋转和溶液注入进行麻醉时，大多数儿童报告无疼痛或轻度疼痛。这项技术有望供训练有素的儿童牙医使用。
