まとめ
トラウマ重症治療室 (TICU) での中枢静脈カテーテリゼーションのための超音波誘導下垂動脈アプローチ (UAVC) は,高静脈血栓塞栓症 (VTE) 率と非最適のカテーテル先の配置を示しています. 重傷患者の治療結果を改善するために 標準化されたプロトコルが必要です
科学分野:
- クリティカル ケア 医療
- 血管へのアクセス手順
- トラウマ 手術
背景:
- 中枢静脈カテーテリゼーション (CVC) のための超音波誘導下静脈アプローチ (UAVC) は有効ですが,トラウマケアでは十分に活用されていません.
- UAVCの慣行,最適なカテーテル位置,およびトラウマ重症治療室 (TICU) に関連する合併症に関するデータは限られている.
研究 の 目的:
- TICUでのUAVCの実践を特徴づけること.
- カテーターの最適な位置,処置に関連する合併症,不正確な位置と静脈血栓塞栓 (VTE) の危険因子を調査する.
主な方法:
- 2021年10月から2023年4月までの間にUAVCを受けた132人のトラウマ患者の遡及分析.
- 患者の人口統計,処置の詳細,緊急 (例えば,肺胸腫,血腫) と遅い合併症 (VTE,CRBSI) の文書化.
- カテーテル先の非最適な配置とVTEの危険因子を特定するためのロジスティック回帰分析
主要な成果:
- 高頻度 (27. 3%),特に高齢患者 (43. 4%).
- カテーテル先の最適な位置の低率 (29. 8%) で,左側の位置が不正確さの重要な危険因子である.
- 不正確な位置付けに関連する要因には,患者の年齢,肥満,左側位置付けが含まれていました. VTEは,高齢化,発熱,および呼吸器の長期間と関連していました.
結論:
- 重度のトラウマ患者のUAVCは,高いVTE率と,カテーターの先の位置が悪いことと関連しています.
- 標準化されたプロトコルは,カテーテル先の位置の精度を改善するために不可欠です.
- ランダム化制御試験を含むさらなる研究は,トラウマケアにおけるUAVCを最適化するために正当化されています.

Venous Thrombosis III: Interprofessional Care
22
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
557
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

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,...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
