Smartphone-controlled patch electro-acupuncture (SCEA) is a novel device which gives the same analgesic effect as with conventional acupuncture. There are no published articles in the English literature on the use of this device as a primary mode of pain relief during colonoscopy. Primary aims of this study were to investigate the efficacy of SCEA as a substitute for pain relief during colonoscopy.
Thirty-seven patients were randomized to receive SCEA (n = 19) or placebo (n = 18) during colonoscopy. Additional rescue sedation was administered to patients if they had pain or discomfort during the procedure. Visual analogue scale was used to quantify the intensity of pain from the beginning to end of the procedure. Other variables analysed were the amount of sedation used, duration from start to caecal intubation, length of time for completion of colonoscopy and recovery time to home discharge.
Patients who received SCEA had a lower median pain score of 4.6 (interquartile range 5.7) compared to the placebo group of 6.0 (interquartile range 3.2). Statistical analysis comparing the groups revealed a non-significant P-value of 0.12, although more than 90% of the patients indicated willingness for SCEA as the primary analgesia if they were to repeat the procedure. Throughout the study, there were no adverse complications that occurred during the use of SCEA.
Even though this study did not demonstrate, a significance in pain reduction, SCEA remains a safe modality which, more than 90% of patients favoured as a substitute for pain relief during colonoscopy.
智能手机控制的贴片式电针（SCEA）是一种新型设备，其镇痛效果与传统针灸相同。英文文献中尚无关于将该设备用作结肠镜检查期间主要疼痛缓解方式的报道。本研究的主要目的是调查SCEA作为结肠镜检查期间疼痛缓解替代方法的疗效。
37例患者在结肠镜检查期间被随机分为接受SCEA组（n = 19）或安慰剂组（n = 18）。如果患者在检查过程中出现疼痛或不适，则给予额外的急救镇静。使用视觉模拟量表从检查开始到结束对疼痛强度进行量化。分析的其他变量包括使用的镇静剂量、从开始到盲肠插管的持续时间、结肠镜检查完成的时间以及回家出院的恢复时间。
与安慰剂组中位数疼痛评分6.0（四分位间距3.2）相比，接受SCEA的患者中位数疼痛评分为4.6（四分位间距5.7）。比较两组的统计分析显示P值为0.12，无统计学意义，尽管超过90%的患者表示如果重复该检查，愿意将SCEA作为主要镇痛方法。在整个研究过程中，使用SCEA期间未发生不良并发症。
尽管本研究未显示疼痛减轻有统计学意义，但SCEA仍然是一种安全的方式，超过90%的患者倾向于将其作为结肠镜检查期间疼痛缓解的替代方法。
