Perception and relief of pain were studied in a varied group of fifty patients who had undergone laparotomy with upper abdominal midline incisions. Twenty-six patients were supplied with functioning transcutaneous electrical stimulators. Twenty-four received nonfunctioning machines. The controls were randomized by a nurse not otherwise involved in this study. Only seventeen of the total study group were judged failures and six of the patients had been receiving preoperative narcotics. Patient response was very favorable and pain relief was good to excellent, especially in one group with working stimulators (p is less than 0.008). Patients with known malignant disease did not respond as well as those with benign disease although anxiety may have been an important factor here. Use of the transcutaneous electrical stimulator would seem particularly worthwhile for patients undergoing elective abdominal operations for benign disease with no history of narcotic usage. Briefing the patient preoperatively on the potential value of transcutaneous electrical stimulation as a method of pain relief may improve end-results.
对五十名接受过上腹部正中切口剖腹手术的不同患者的疼痛感知与缓解情况进行了研究。二十六名患者配备了可正常工作的经皮电刺激器。二十四名患者则收到了无法正常工作的仪器。对照组由未参与本研究的护士进行随机分组。在整个研究组中，仅有十七名被判定为治疗失败，且有六名患者术前一直在使用麻醉药。患者的反应非常良好，疼痛缓解效果良好至极佳，尤其是在使用可正常工作的刺激器的一组中（p小于0.008）。已知患有恶性疾病的患者的反应不如患有良性疾病的患者，尽管焦虑在此可能是一个重要因素。对于接受择期腹部良性疾病手术且无麻醉药使用史的患者，使用经皮电刺激器似乎特别值得。术前向患者介绍经皮电刺激作为一种缓解疼痛方法的潜在价值可能会改善最终结果。
