Abstract:
作为医院感染的来源之一, 患者皮肤表面(载体)存在潜在有害细菌, 它们不会产生感染, 但在某些条件下可能传播给其他人。皮肤表面生活的细菌也会导致湿疹恶化。目前去除这些微生物(细菌)皮肤的方法包括给患者使用局部抗生素(皮肤上的)或口服抗生素(口服),但随着时间的推移, 这种策略被认为导致了抗生素耐药性, 这意味着抗生素不再能杀死细菌。本文中描述的是由德国雷根斯堡大学的一个小组进行的研究。他们使用切掉的猪和人体皮肤样本, 在样本中加入耐药细菌,如耐甲氧西林葡萄球菌或 MRSA, 然后用一种化学溶液对皮肤进行处理, 这种化学溶液的作用是增加对光的敏感性。皮肤样本随后暴露在光源下,这一过程被称为光动力激活。他们发现这种技术可以在不损害皮肤细胞的情况下, 大量减少细菌的数量。作者建议,这一过程现在应该作为一种更安全的方法来研究, 以减少表面细菌运输, 而不增加细菌耐药性的风险,也不损害皮肤。Cite

Seperti pada dewasa, teknik regional anestesi pada pediatrik kini makin popular digunakan oleh ahli anestesikarena keuntungannya. Namun demikian selalu ada risiko dan kemungkinan timbulnya komplikasi dari setiap tindakan yang dilakukan, termasuk tindakan anestesi regional pada pediatrik.

Komplikasi bisa diakibatkan dari identifikasi ruang saraf, alat, obat, teknis tindakan anestesi regionalnya dan komplikasi lainnya.Walaupun tidak banyak kejadian komplikasi regional anestesi yang dilaporkan pada pediatrik, dan bukanlah komplikasi yang fatal, teknik regional anestesi pada pediatrik harus dilakukan dengan lebih hatihati, pertimbangan risiko dan keuntungannya untuk menghindari terjadinya komplikasi, terlebih karena kebanyakan komplikasi dapat dihindari dengan mempelajari teknik yang benar, menggunakan peralatan yang sesuai, dan sangat menerapkan prinsip keamanan pada pasien dengan baik.
