Propofol Làm Giảm Đường Ngưỡng Co Mạch và Run Lắc Một Cách Tuyến Tính Dịch bởi AI
Giới thiệu
Nhiệt độ da nên được giữ ổn định khi xác định ngưỡng phản ứng vì cả nhiệt độ da và nhiệt độ lõi đều đóng góp vào việc kiểm soát điều hòa nhiệt. Tuy nhiên, trong thực tế, khó khăn trong việc đánh giá cả ngưỡng nóng và lạnh trong khi vẫn giữ nhiệt độ da không thay đổi. Một nghiên cứu gần đây cho thấy ngưỡng co mạch và run... ... hiện toàn bộ

Protective versus Conventional Ventilation for SurgeryAbstract
Background:
Recent studies show that intraoperative mechanical ventilation using low tidal volumes (VT) can prevent postoperative pulmonary complications (PPCs). The aim of this individual patient data meta-analysis is to evaluate the individual associations between VT s... ... hiện toàn bộ

Internal Jugular Vein and Carotid Artery Anatomic Relation as Determined by Ultrasonography
Background
Cannulation of the internal jugular vein (IJV) is associated with a 95% success rate when external landmarks are used. Anatomic variability has been implicated as the cause for difficulty in cannulation without ultrasound. In contrast to an IJV located lateral to the carotid artery (CA), an IJV overlying the CA may resu... ... hiện toàn bộ

Intrathecal α2-Adrenergic Agonists Stimulate Acetylcholine and Norepinephrine Release from the Spinal Cord Dorsal Horn in Sheep
Background
Intrathecal injection of clonidine and dexmedetomidine produce behavioral analgesia by an alpha 2-adrenergic mechanism. Functional and anatomic studies suggest that this analgesia is mediated by cholinergic activation. This hypothesis was directly tested by measuring extracellular acetylcholine concentrations in spinal ... ... hiện toàn bộ

Intravenous Opioids Stimulate Norepinephrine and Acetylcholine Release in Spinal Cord Dorsal Horn
Background
Opioids produce analgesia by direct effects as well as by activating neural pathways that release nonopioid transmitters. This study tested whether systematically administered opioids activate descending spinal noradrenergic and cholinergic pathways.

Location and Characteristics of Nitric Oxide Synthase in Sheep Spinal Cord and Its Interaction with α2-Adrenergic and Cholinergic Antinociception
Background
Nitric oxide synthase is located in the spinal cord dorsal horn and intermediolateral cell column, where it may modulate sensory and sympathetic neuronal activity. However, the biochemical characteristics of this enzyme have not been examined in these different areas in the spinal cord. Although alpha(2)-adrenergic agon... ... hiện toàn bộ

Effects of Intrathecal Neostigmine, Bupivacaine, and Their Combination on Sympathetic Nerve Activity in Rats
Background
Intrathecal injection of local anesthetic agents is associated frequently with hypotension. Conversely, intrathecal administration of neostigmine increases blood pressure by enhancing the accumulation of acetylcholine in the spinal cord. The current study examined directly the interaction of intrathecal injection of bup... ... hiện toàn bộ

Interaction between Intrathecal Neostigmine and Epidural Clonidine in Human Volunteers
Background
alpha 2-Adrenergic agonists are thought to produce analgesia, in part, by activating spinal acetylcholine release. The purpose of the current study was to examine the interaction between intrathecal neostigmine and epidural clonidine for analgesia and side effects in humans.
