概括
与正常盐水和povidone-iodine相比,基酸 (CHG) 在腰部融合手术期间显著降低了植入物表面的细菌污染. 这项研究强调了CHG作为脊柱手术的有希望的消毒剂,以对抗手术部位感染.
科学领域:
- 整形外科手术 整形外科手术
- 传染性疾病 传染性疾病
- 抗菌剂 抗菌剂 抗菌剂
背景情况:
- 手术部位感染 (SSI) 是仪器脊柱手术的一个重要并发症,增加了患者的发病率和医疗费用.
- 标准的手术前消毒方案不能完全消除细菌污染,需要进一步的预防策略.
- 不同的手术内消毒剂解决方案在脊柱手术中减少污染的比较有效性尚未得到充分证实.
研究的目的:
- 评估使用常规盐水 (NS),波维- (PVP-I) 和素酸盐 (CHG) 浸泡手术内消毒剂溶液在减少细菌污染方面的有效性.
- 在腰部仪器融合手术期间评估表面组织,深层组织和植入物表面的细菌减少.
- 在不同消毒剂组中比较术后SSI和临床并发症的发生率.
主要方法:
- 一个单中心,单盲,随机对照试验,涉及105名患者接受后腰椎体融合.
- 患者被随机分为三个组:正常盐水 (NS),波维- (PVP-I) 或素酸盐 (CHG),每组接受3分钟的浸泡.
- 从三个地点采集了手术内抽样,用于细菌培养和16S rRNA PCR分析.
主要成果:
- 正常的盐水显示没有显著的细菌减少. 波维-证明了表面污染的减少,但在更深层的组织或植入物中没有.
- 赫西丁葡萄酸盐 (CHG) 显示出最大的细菌减少,在植入物表面显著超过NS和PVP-I.
- 尽管细菌减少有显著差异,但术后SSI的发生率在所有组中都是低的和可比的,没有与消毒剂相关的并发症.
结论:
- 在腰部融合手术中,即使经过标准消毒,细菌污染仍然存在;手术期间的消毒灌可以进一步降低这种负担.
- 在减少细菌污染方面,素酸盐 (CHG) 优于普通盐水和波维-,特别是在植入物表面.
- 作为脊柱外科手术的手术内消毒剂,CHG显示出有前景,因此需要进一步的多中心研究来证实其对减少SSI和长期结果的影响.

Hand hygiene
3.1K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Surface Membrane Barriers
675
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Local Anesthetics: Clinical Application as Spinal Anesthesia
555
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
