The purpose of this study was to determine whether the new reciprocating procedure device (RPD) is superior to the conventional syringe for the administration of local anesthesia. There were 209 local lidocaine anesthesia procedures randomized between the RDP and the conventional syringe. Outcome measures included administration time, anesthesia pain, procedure pain, and operator satisfaction. The RPD significantly reduced anesthesia administration time by 49% (RPD: 0.68 +/- 0.59 min, Syringe: 1.32 +/- 1.01 min, p < 0.001, 95% confidence interval [CI] for % reduction: 36%-60%), reduced anesthesia pain by 27% (RPD visual analog pain scale score: 4.05 +/- 2.64; Syringe: 5.55 +/- 3.00; p < 0.001, 95% CI 14%-38%), reduced significant procedure pain by 74% (p < 0.001, 95% CI 60%-87%), and improved physician satisfaction by 63% (p < 0.001, 95% CI 53%-74%). The RPD markedly reduces the pain associated with lidocaine anesthesia administration, reduces administration time, and maintains the effectiveness of local anesthesia. The RPD is superior to and significantly more effective than the conventional syringe for the administration of local lidocaine anesthesia.
本研究的目的是确定新型往复式操作装置（RPD）在局部麻醉给药方面是否优于传统注射器。共有209例局部利多卡因麻醉操作在RDP和传统注射器之间进行随机分组。观察指标包括给药时间、麻醉疼痛、操作疼痛和操作者满意度。RPD显著缩短了麻醉给药时间49%（RPD：0.68±0.59分钟，注射器：1.32±1.01分钟，p<0.001，减少百分比的95%置信区间[CI]：36%-60%），减轻了27%的麻醉疼痛（RPD视觉模拟疼痛量表评分：4.05±2.64；注射器：5.55±3.00；p<0.001，95%CI 14%-38%），显著减轻了74%的操作疼痛（p<0.001，95%CI 60%-87%），并使医生满意度提高了63%（p<0.001，95%CI 53%-74%）。RPD显著减轻了与利多卡因麻醉给药相关的疼痛，缩短了给药时间，并维持了局部麻醉的效果。在局部利多卡因麻醉给药方面，RPD优于传统注射器且显著更有效。
