Postoperative pain may be experienced after breast augmentation surgery despite advances in surgical techniques which minimize trauma. The use of pharmacologic analgesics and narcotics may have undesirable side effects that can add to patient morbidity. This study reports the use of a portable and disposable noninvasive pulsed electromagnetic field (PEMF) device in a double-blind, randomized, placebo-controlled pilot study. This study was undertaken to determine if PEMF could provide pain control after breast augmentation.
Forty-two healthy females undergoing breast augmentation for aesthetic reasons entered the study. They were separated into three cohorts, one group (n = 14) received bilateral PEMF treatment, the second group (n = 14) received bilateral sham devices, and in the third group (n = 14) one of the breasts had an active device and the other a sham device. A total of 80 breasts were available for final analysis. Postoperative pain data were obtained using a visual analog scale (VAS) and pain recordings were obtained twice daily through postoperative day (POD) 7. Postoperative analgesic medication use was also followed.
VAS data showed that pain had decreased in the active cohort by nearly a factor of three times that for the sham cohort by POD 3 (p < 0.001), and persisted at this level to POD 7. Patient use of postoperative pain medication correspondingly also decreased nearly three times faster in the active versus the sham cohorts by POD 3 (p < 0.001).
Pulsed electromagnetic field therapy, adjunctive to standard of care, can provide pain control with a noninvasive modality and reduce morbidity due to pain medication after breast augmentation surgery.
尽管手术技术不断进步，能将创伤降至最低，但隆胸手术后仍可能出现术后疼痛。使用药物止痛剂和麻醉剂可能会产生不良副作用，增加患者的发病率。本研究报告了在一项双盲、随机、安慰剂对照的初步研究中使用便携式一次性无创脉冲电磁场（PEMF）设备的情况。本研究旨在确定PEMF是否能在隆胸后控制疼痛。
42名因美容原因接受隆胸手术的健康女性进入该研究。她们被分为三组，一组（n = 14）接受双侧PEMF治疗，第二组（n = 14）接受双侧假设备，第三组（n = 14）一侧乳房使用有源设备，另一侧使用假设备。共有80个乳房可供最终分析。使用视觉模拟量表（VAS）获取术后疼痛数据，并在术后第7天每天两次记录疼痛情况。同时记录术后止痛药物的使用情况。
VAS数据显示，到术后第3天，有源组的疼痛减轻程度几乎是假手术组的三倍（p < 0.001），并持续到术后第7天。到术后第3天，有源组患者术后止痛药物的使用量相应地比假手术组减少速度快近三倍（p < 0.001）。
作为标准治疗的辅助手段，脉冲电磁场疗法可以通过无创方式控制疼痛，并降低隆胸手术后因止痛药物导致的发病率。
