まとめ
術後幻覚は心臓手術患者の約10%に影響を与え、視覚幻覚がより一般的です。リスク因子と保護因子は手術の種類によって異なり、患者のモニタリングと予防戦略の個別化が必要です。
科学分野:
- 神経科学
- 循環器病学
- 精神医学
背景:
- 幻覚は、心臓手術後の頻繁に見過ごされる神経精神医学的合併症です。
- 冠動脈バイパス術(CABG)および弁置換術後の視覚および聴覚幻覚の発生率と特定の予測因子に関するデータは限られています。
研究 の 目的:
- CABGおよび弁置換術を受けた患者における視覚および聴覚幻覚の発生率を調査し、その予測因子を特定すること。
- 術後幻覚に対する個別化されたモニタリングおよび予防戦略を支持するデータを提供すること。
主な方法:
- 1332人の成人患者(CABG 997人、弁置換術 335人)を対象とした多施設共同前向きコホート研究を実施しました。
- 術後7日間、毎日精神病体験質問票を用いて患者を評価しました。
- 視覚および聴覚幻覚の予測因子を評価するために、コックス比例ハザードモデルを使用しました。
主要な成果:
- CABG患者の11.5%、弁置換術患者の10.0%に視覚幻覚が認められました。CABG患者の7.0%、弁置換術患者の5.0%に聴覚幻覚が報告されました。予測因子は手術の種類によって異なり、左室駆出率の低下、大動脈遮断時間の延長、免疫抑制療法、術後輸血、術後長期人工呼吸管理、ノルアドレナリン使用、アドレナリン曝露が含まれていました。
結論:
- 心臓手術後の患者の約10人に1人が術後幻覚を経験します。
- 視覚幻覚は聴覚幻覚よりも頻繁に発生します。
- 幻覚のリスク因子と保護因子は、CABGと弁置換術の間で異なり、個別化されたケアの必要性を強調しています。

Positive Symptoms Schizophrenia: Hallucinations and Delusions
514
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

The Auditory Ossicles
3.0K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Auditory Pathway
7.2K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking...

Auditory Perception
1.1K
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
