概括
与全静脉麻醉 (TIVA) 相比,sevoflurane麻醉减少了结直肠癌患者的循环瘤细胞和炎症. 这表明挥发性麻醉剂可能会降低短期复发风险.
科学领域:
- 在瘤学瘤学.
- 麻醉学 麻醉学
- 手术瘤学手术瘤学
背景情况:
- 手术创伤和麻醉可以影响瘤微环境和结直肠癌 (CRC) 的复发.
- 已知sevoflurane的体外抗瘤作用,但其对CRC细胞增殖和传播的临床影响尚不清楚.
研究的目的:
- 为了确定是否sevoflurane麻醉减弱早期瘤细胞活动与TIVA相比.
- 评估循环瘤细胞 (CTC),全身炎症以及扩散和亡的组织生物标志物.
主要方法:
- 一项前性,随机对照性研究,涉及80名经过彻底切除的CRC患者.
- 患者被分配到塞沃兰或TIVA.
- 分析了周围血液和切割样本的CTC,炎症标记物 (IL-6,TNF-α,CRP) 和生物标记物 (Ki-67,PCNA,Bax,Bcl-2,caspase-3).
主要成果:
- 与TIVA (B组) 相比,sevoflurane组 (A组) 在手术后1,3和7天的CTC计数较低.
- 组A的炎症标志物 (IL-6,CRP) 和减少的增殖标志物 (Ki-67,PCNA) 显著降低.
- 一个月后,A组表现出亡标记的增加 (Bax/Bcl-2比率,caspase-3) 和稳定的瘤标记 (CEA,CA19-9),与B组不同.
结论:
- 黄麻醉可以降低结直肠癌患者的短期复发风险.
- 研究结果支持这样一个假设,即挥发性麻醉剂在临床环境中具有潜在的抗瘤作用.
- 需要进行更大,更长期的试验来验证瘤学结果.

General Anesthesia: Overview
1.1K
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Drugs for Peptic Ulcer Disease: Sucralfate as Mucosal Protective Agents
2.4K
In the intricate landscape of the gastric lumen, excessive acid secretion disrupts the natural defense mechanisms, weakening the mucus-bicarbonate barrier. This vulnerability allows pepsin to infiltrate epithelial cells, digesting mucosal proteins and triggering erosion, leading to ulcer formation.
In this scenario, mucosal protective agents like sucralfate play an essential role. Sucralfate, a complex of sulfated sucrose and aluminum hydroxide, demonstrates its usefulness in acidic conditions,...

Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.

Drugs for Treatment of Ulcerative Colitis in IBD
721
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
937
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
1.2K
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
