概括
通过剖腹产产的晚期早产婴儿显示氧和延迟,但在10分钟内达到适当水平. 稳定的新生儿可能不需要常规氧气.
科学领域:
- 新生儿医学 新生儿医学
- 儿科肺病学 儿科肺病学
- 产周研究 产周研究
背景情况:
- 晚期早产新生儿 (34-36周孕期) 需要仔细监测产后的氧化情况.
- 剖腹产和延迟带紧可以影响新生儿的过渡.
- 确定氧和度的参考范围对于及时干预至关重要.
研究的目的:
- 为了在生命的前10分钟内在晚期早产新生儿中建立前导外周氧和 (SpO2) 的参考范围.
- 评估在这个人群中达到目标SpO2水平所需的时间.
- 评估通过剖腹产产产生的临床稳定的晚期早产新生儿日常补充氧气的必要性.
主要方法:
- 对200名晚期早产新生儿进行前性观察研究,这些新生儿是通过剖腹产与延迟带紧的剖腹产产产生的.
- 在出生后2到10分钟,每分钟持续监测先导体SPO2,心率和体温.
- 在2022年4月至2024年9月期间,在印度的一家三级医院收集的数据.
主要成果:
- 在2,5,10分钟的中位 SpO2 分别为77%,88%和95%.
- 达到≥80%的SpO2的时间为4分钟,≥85%为5分钟,≥90%为6分钟.
- 73.3%在5分钟内达到≥80%的SpO2;98.8%在没有干预的情况下在10分钟内达到≥85%的SpO2.
结论:
- 很大一部分健康的晚期早产新生儿在5分钟后还没有达到新生儿复苏计划 (NRP) 的氧和值.
- 几乎所有婴儿在没有干预的情况下,在10分钟内达到≥85%的SpO2,这表明了足够的心肺呼吸过渡.
- 对于通过剖腹产产产生的稳定的晚期早产新生儿,常规补充氧气可能是不必要的,这需要进一步调查.

Special considerations while measuring oxygen saturation
910
Assessing respiratory rate concurrently with pulse measurement is fundamental to patient care, providing valuable insights into the patient's respiratory function. The normal breathing rate for an adult usually falls within a normal range of 12 to 20 breaths per minute. Abnormal respiratory rates can signal underlying health conditions or the need for immediate intervention.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
2.0K
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Oxygen Delivering System I: Nasal Cannula and Face Mask
1.5K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Oxygen Delivering System III: Tracheostomy and T-piece
5.7K
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Observational Studies
10.7K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Solution Equilibrium and Saturation
21.6K
Imagine adding a small amount of sugar to a glass of water, stirring until all the sugar has dissolved, and then adding a bit more. You can repeat this process until the sugar concentration of the solution reaches its natural limit, a limit determined primarily by the relative strengths of the solute-solute, solute-solvent, and solvent-solvent attractive forces. You can be certain that you have reached this limit because, no matter how long you stir the solution, undissolved sugar remains. The...
