まとめ
小児重症治療の臨床医は,既存のガイドラインにもかかわらず,テクニックと指示を含む動脈カテーテル置換の慣行に大きな違いを示しています. 超音波の使用を標準化し,患者の治療結果を改善するためにさらなる研究が必要です.
科学分野:
- 小児重症治療薬
- 医療機器の配置
- 臨床 実践 の 変化
背景:
- 集中治療における動脈カテーテル (AC) の用法に関するコンセンサスの欠如.
- ACの使用と改善された患者のアウトカムを結びつける確固たる証拠はありません.
- 小児集中治療室 (PICU) におけるAC利用の有意な変動は,患者の重症度とは無関係です.
研究 の 目的:
- 小児重症治療の臨床医の間で動脈カテーテル置換の実践を調査する.
- ACの使用に関する技術,指示,態度の違いを特定する.
- 小児ICUにおける現在の実用的な実践を特徴づける.
主な方法:
- 匿名で横断的なウェブベースの調査です.
- 93の施設の377人の小児重症医療従事者から収集したデータです
- 技法や場所の選び方 動脈カテーテル設置の指示について尋ねました
主要な成果:
- インターンシップ中の超音波の使用は,52.0%の回答者が報告し,フェローは主治医よりも多く使用しました.
- セルディンガー技術 (キャセター・オーバー・ワイヤ) が主たる挿入方法であった (88. 1%).
- 周縁および中央カヌレーションでは,放射性動脈 (97. 3%) と股関節動脈 (81. 1%) が好ましい. 症状の有意な変動は68. 9%で単一の血管活性が認められた.
結論:
- 既存のガイドラインにもかかわらず,小児ICUの臨床医の間では,大動脈カテーテル置換の幅広い慣行が続いている.
- 超音波誘導技術と固定方法に関する証拠のギャップは,さらなる調査を必要とする.
- 研究を通じて実践を最適化することは 小児重症治療における患者の成果を改善するために不可欠です

Parentral Nutrition: Centeral and Peripheral Parental Nutrition
300
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
