まとめ
血管内血栓回収療法(EVT)におけるヘリコプター救急医療サービス(HEMS)搬送は、陸路搬送と同等の転帰を示し、移動時間が長かった。これは、HEMSが包括的脳卒中センター(CSC)でのEVTを必要とする患者にとって実行可能な選択肢であることを示唆している。
科学分野:
- 神経科学
- 心血管医学
- 救急医学
背景:
- 血管内血栓回収療法(EVT)は、包括的脳卒中センター(CSC)への搬送を必要とすることが多い重要な脳卒中治療である。
- 一次脳卒中センター(PSC)に最初に搬送された患者は、陸路救急車またはヘリコプター救急医療サービス(HEMS)で搬送される可能性がある。
研究 の 目的:
- HEMSによるEVT搬送と都市部搬送群の転帰を比較する。
- 脳卒中患者の適時EVTを促進する上でのHEMSの有効性と安全性を評価する。
主な方法:
- 地域脳卒中ネットワークにおける後向き観察研究。
- 全国EVT登録データを用いたHEMS搬送と、直接CSC搬送および都市部PSCからCSCへの搬送との比較。
- 主要転帰:90日機能的自立度(修正ランキン尺度0-2);副次的転帰:90日死亡率。
主要な成果:
- HEMS患者(28%)は、都市部グループと比較して、発症からEVT鼠径部までの時間が長かったが、90日機能的自立度および死亡率は同様であった。
- HEMSと都市部PSCからCSCへの搬送群の間で、90日自立度に有意差は観察されなかった。
- 直接CSC搬送患者は、より良好な自立度への傾向を示したが、全体的な死亡率は全群で同様であった。
結論:
- EVTのためのHEMS搬送は、移動距離と時間が長かったにもかかわらず、都市部搬送と同等の機能的転帰をもたらす。
- 包括的脳卒中センターは、転帰が悪化しないため、EVTのための遠隔PSCからのHEMS搬送を検討すべきである。
- 本研究は、EVTへのアクセスを拡大するために、脳卒中ネットワークへのHEMSの統合を支持するものである。

Distance Problem
63
When an object's velocity changes over time, the total distance traveled can be determined by summing small displacement intervals over short increments. This approach approximates the true distance through numerical summation and the use of integral calculus. An estimate of the total displacement can be obtained by measuring velocity at regular intervals and multiplying each value by the corresponding time step.If a runner accelerates over the first three seconds of a race, speed measurements...

Distance Corrections
282
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

The Distance Formula
637
In geometry, measuring the direct distance between two points on a plane is essential in various practical and theoretical applications. Whether in navigation, engineering, or computer graphics, determining the shortest path between two locations involves using the distance formula. This formula is derived from the Pythagorean Theorem, which relates the lengths of the sides of a right triangle. On a coordinate plane, the horizontal and vertical distances between two points serve as the legs of...

Short-distance Transport of Resources
17.6K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Distance Measurements by Taping
445
Tapes are essential in surveying for accurate, durable, and short-distance measurements. Made from lightweight, nylon-coated steel, they offer flexibility and strength for rugged outdoor use. The nylon coating protects against rust and wear, extending the tape's life. Standard lengths, around 30 meters, are marked in meters and millimeters for precision.Surveyors select tapes based on site conditions and accuracy needs. Lightweight, nylon-coated tapes are commonly used for ease of handling and...

Electronic Distance Measuring Instruments
503
Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...
