まとめ
短い手術中に強制的な空気加熱を省略すると,患者の低体温と震えが増加しました. これはコストと炭素排出量を削減しますが,患者の治療結果への影響については,さらなる調査が必要です.
科学分野:
- アネステシオロジー アネステシオロジー
- 患者の安全性についてです.
- 健康経済学 医療経済学
背景:
- 一回使用可能な強制空気加熱毛布は,手術中の低体温を予防しますが,環境的,経済的コストを負います.
- 短期間の手術のためにこれらの毛布を省略した結果,患者のアウトカムへの影響は十分に理解されていません.
研究 の 目的:
- 短時間の外科処置中のや低体温に対する強制空気加熱の除去の影響を評価する.
主な方法:
- プラグマティックで前向きな前後のコホート研究が2023年に中等大学病院で実施されました.
- 90分未満の整形外科または腹腔外科の手術を受けた成人の患者も含まれていました.
- コプライマリアウトカムは,手術中の低体温 (<35.5°C) と麻酔後のケアユニット (PACU) の震え,アクティブ・フォース・エア加熱と無加熱を比較した.
主要な成果:
- 強制的な空気加熱を省略すると,手術中の低体温 (5.58%対2.73%) と (6.1%対4.0%) が著しく増加しました.
- 1回の震えを防ぐための推定コストは235ドルと62.9キログラムのCO2相当量でした.
- 麻酔の発生時間やPACUの滞在期間において有意な差異は認められなかった.
結論:
- 短時間の手術のために強制的な空気加熱を取り除くと,低体温との発生率が著しく増加しました.
- この慣行は,コストと炭素排出量を削減し,患者の福祉と環境/経済的利益の間の議論の余地のあるバランスを提示します.
- 熱的快適性に関する患者の見解を探るため,さらなる研究が必要である.

Decreased Body Temperature
1.1K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Temperature Measurement Sites
3.5K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...
