- 传染病控制和控制传染病
- 微生物学 微生物学
背景情况:
- 手术部位感染 (SSI) 是骨科手术中的一个重要问题.
- 杆菌 (C. acnes) 是一个常见的病原体,涉及到肩膀手术SSI.
- 标准的手术前皮肤消毒可能无法在所有组织层中完全根除C. acnes.
研究的目的:
- 评估三重预防方案在减少手术内C. acnes污染的有效性.
- 为了比较标准PV-I消毒,双重预防 (皮下PV-I) 和三重预防 (手术前氧化加PV-I) 的有效性.
主要方法:
- 一项随机对照试验,涉及156名接受肩膀手术的患者.
- 三组:控制 (标准PV-I皮肤消毒),双重预防 (PV-I皮肤和皮肤下组织) 和三重预防 (氧化手术前,PV-I皮肤和皮肤下组织).
- 组织层,设备和手套的内科培养被分析为C. acnes.
主要成果:
- 三重预防在关节内培养中显著降低了C. (10%对照组为32%,p=0.031).
- 肌肉层中的C.也在三重预防下显著降低 (13%对比42%对照,p=0.0052).
- 阳性培养物的中位数在三重预防组中最低.
结论:
- 在手术前联合使用氧化和皮下用波维-消毒,可以有效地减少手术内C. acnes.

Blind Procedures
13.6K
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...

Blinding
4.0K
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.

Muscles of the Shoulder
9.2K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Muscles that Move the Arm
4.8K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Clinical Trials: Overview
5.0K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Trial and Error and Algorithm
424
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...
