Coughing and deep breathing after sternotomy causes severe pain. This study was conducted to assess the effect of cold therapy on the pain in patients undergoing open heart surgery.
In a randomized controlled trial (RCT) with crossover design, 50 eligible and consenting patients were recruited and randomly allocated to gel pack and non-gel pack groups on the first postoperative day. All patients performed four episodes of deep breathing and coughing (DB and C) every 2 h. Pain intesity was measured and compared at rest and after DB and C in both groups. At the end of the study, all patients were asked about their preferences for the cold gel pack application prior to DB and C. The study hypotheses were analyzed using repeated measures analysis of variance (RM-ANOVA).
Data analysis showed significant reduction in pain scores (P < 0.001) after cold gel application. Forty-five (90%) patients were inclined to reapply the gel pack in the future.
Cold gel pack can reduce the pain associated with DB and C in cardiac surgery patients.
胸骨切开术后咳嗽和深呼吸会引起剧痛。本研究旨在评估冷疗法对心脏直视手术患者疼痛的影响。
在一项采用交叉设计的随机对照试验（RCT）中，招募了50名符合条件并同意参与的患者，并在术后第一天将其随机分为凝胶包组和非凝胶包组。所有患者每2小时进行4次深呼吸和咳嗽（DB和C）。测量并比较两组患者在休息时以及进行DB和C之后的疼痛强度。在研究结束时，询问所有患者在进行DB和C之前对使用冷凝胶包的偏好。使用重复测量方差分析（RM-ANOVA）对研究假设进行分析。
数据分析显示，应用冷凝胶后疼痛评分显著降低（P < 0.001）。45名（90%）患者倾向于在未来再次使用凝胶包。
冷凝胶包可减轻心脏手术患者与DB和C相关的疼痛。
