概括

乳牛中菌糊的散发导致伤口愈合缓慢,平均需要18.8周才能完全恢复. 这些伤口还显示了至少在手术后六周的敏感性增加.

科学领域:

兽医医学兽医医学兽医医学
动物福利科学动物福利科学
皮肤病学皮肤病学

背景情况:

在美国的商业乳制品农场中,Caustic paste的散布正在获得引力.
有限的研究存在于长期疼痛和福利影响的腐蚀性糊口散花.
热铁散开的伤口通常需要7-9周才能愈合.

研究的目的:

为了研究和描述伤口愈合过程和敏感性,在乳牛牛的腐蚀性糊口脱落后.
为了比较愈合时间和敏感度的性糊口散花伤口与既定的文献值.

主要方法:

泽西州和荷尔斯坦州的雌性小牛 (n=18) 在3天大时被用性糊涂;对照组 (n=15) 接受了虚假手术.
小牛接受局部麻醉和NSAIDs. 每周对组织类别进行伤口愈合监测,包括重新上皮化.
每周测量机械感知值 (MNT),以评估伤口的敏感性.

主要成果:

伤口的长期愈合,需要16.2±5.7周的重新上皮化和18.8±6周的完全愈合.
在手术后至少6周内,伤口仍然比完整的组织显著更敏感 (MNT较低).
愈合时间大约是热铁制方法报告的两倍.

结论:

与体方法相比,体粘合剂散花的结果是明显更长的伤口愈合时间 (18.8周) 和延长的敏感性 (6周).
需要进一步的研究来优化粘贴应用技术 (数量,持续时间,小牛的年龄,疼痛管理),以改善治愈结果.

Phases of Wound Repair

Phases of Wound Repair

Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
