概括
负压伤疗法 (NPWT) 在柱状鼻疾病 (PSD) 切除中没有降低外科创伤脱离率. 这项研究表明,NPWT不是PSD手术伤口的常规预防措施.
科学领域:
- 手术创新和伤口愈合研究.
- 临床试验方法在外科手术的结果.
背景情况:
- 柱状鼻疾病 (PSD) 手术的并发症率很高,包括手术伤口脱光 (SWD),高达44%.
- 负压伤疗法 (NPWT) 是一种潜在的干预措施,以减轻高风险手术伤口中的SWD.
研究的目的:
- 评估NPWT与传统的被动 (CP) 敷料相比,在PSD切除后减少SWD率的有效性.
- 评估NPWT对患者生活质量和PSD手术后恢复正常活动的影响.
主要方法:
- 一个前性,交叉随机受控试验,涉及50名患有PSD的患者 (12-40岁).
- 参与者被随机分配,接受NPWT (SNAP) 或CP (Primapore或Opsite) 的敷料.
- 随访包括定期的伤口评估和为期2个月的术后在线调查,以了解生活质量的结果.
主要成果:
- 整体死亡率为42% (21/50),NPWT组为48%,CP组为36% (P=0.6).
- 两组之间没有观察到深度SWD率,伤口愈合的持续时间,或返回学校/工作的时间,正常坐着或身体活动的显著差异.
- 只有在NPWT组中,SWD与切除尺寸的增加有关 (P=0.03).
结论:
- 在非中线初级关闭的PSD切除术中,NPWT并没有在手术伤口消化或生活质量方面显示出改善的结果.
- 这些发现不支持NPWT作为这些特定手术程序的预防措施的常规使用.
- 进一步的研究可能是有必要的,但目前的证据表明,这种患者群体的益处有限.

Blind Procedures
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...
Blinding
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
