To examine the effectiveness of cryotherapy for reducing postoperative pain in patients who underwent exploratory laparotomy for gynecologic surgery.
Patients who had indication for an exploratory laparotomy gynecologic procedure were selected by attending physicians to undergo abdominal surgery via low transverse skin incision. The participants were randomized into study and control groups with simple random sampling methods. Cold packs were applied at two hours after operation for 6 hours. The visual analog scale (VAS) score was recorded at two, 6, and 12 hours after operation.
One hundred cases were recruited and then divided into study and control groups equally. The mean age of both groups was 43 years. There was no difference in demographics data of both groups. Half of the participants in both groups underwent hysterectomies. At two hours after surgery, both groups had similar VAS scores. The study group had a lower VAS score at 6 and 12 hours after surgery than the control group with statistical difference. Morphine consumption within 24 hours after surgery in both the study and control groups was 2.8±3.4 and 3.0±4.4 mg, respectively, with no statistical difference. However the registration time of the first morphine requirement in the study group was statistically more prolonged than that of the control group. The lengths of hospital stay in both groups were similar. There was no complication reported in this study.
Cryotherapy can reduce postoperative pain. In this presented study the patients who underwent gynecologic surgery had improved pain relief and prolonged time for the first dose of the analgesic drug.
探讨冷冻疗法对接受妇科手术剖腹探查术患者术后疼痛的缓解效果。
由主治医生挑选有剖腹探查术妇科手术指征的患者，经下腹部横切口行腹部手术。采用简单随机抽样方法将参与者随机分为研究组和对照组。术后2小时应用冷敷袋，持续6小时。在术后2、6和12小时记录视觉模拟评分（VAS）。
共招募100例患者，平均分为研究组和对照组。两组的平均年龄均为43岁。两组的人口统计学数据无差异。两组中各有一半的参与者接受了子宫切除术。术后2小时，两组的VAS评分相似。研究组术后6小时和12小时的VAS评分低于对照组，差异有统计学意义。研究组和对照组术后24小时内吗啡消耗量分别为2.8±3.4和3.0±4.4mg，无统计学差异。然而，研究组首次需要吗啡的时间在统计学上比对照组延长。两组的住院时间相似。本研究未报告并发症。
冷冻疗法可减轻术后疼痛。在本研究中，接受妇科手术的患者疼痛缓解得到改善，首次使用镇痛药的时间延长。
