概括
手术前血小板数量低 (<50,000/μL) 且接受牙科手术的患者在手术后面临更高的出血风险. 个人评估至关重要,因为低血小板计数并不是牙科干预的绝对禁忌.
科学领域:
- 口腔外科和牙周科.
- 血液学 血液学 血液学
- 患者安全 患者安全
背景情况:
- 手术前血小板数量低 (血小板缺血) 是手术出血的一个问题.
- 牙科干预,特别是口腔手术,存在术后出血的风险.
- 关于牙科手术在血小板数量低的患者的安全性的证据有限.
研究的目的:
- 在手术前血小板计数低于50,000/μL的患者中,在牙科干预后对术后出血的证据进行综合.
- 为了比较患有血小板数量低的患者的出血率与接受牙科手术的血小板数量正常患者的出血率.
- 为了告知临床决策,关于对血栓塞瘤患者的牙科治疗.
主要方法:
- 进行了没有元分析的定量合成.
- 在Ovid MEDLINE和Embase上进行了广泛的电子文献搜索.
- 包括从1946年到2024年4月发表的研究,没有对设计的限制.
主要成果:
- 该审查包括16项研究,包括983例 (968例口腔手术,10例牙周科,5例牙科麻醉).
- 术后出血发生在血小板计数<50,000/μL的患者中为12.9%,而计数≥50,000/μL的患者中为4.9%.
- 在低血小板计数组中观察到出血的风险比率 (2.95) 显著更高.
结论:
- 手术前血小板数量低 (<50,000/μL) 似乎不是牙科干预的绝对禁忌.
- 然而,手术后出血率较高,特别是在口腔手术后,与血小板数量较低有关.
- 建议对个别患者进行评估,需要进一步进行受控试验,以澄清风险和管理策略.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Bleeding in Fresh Concrete
573
Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...

Nursing Interventions I: Taxonomy of Nursing Interventions
3.8K
Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions
3.3K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:

Relative Risk
2.1K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...
