Shock is a life-threatening condition of circulatory failure. It is a state of cellular tissue hypoxia caused by inadequate oxygen delivery that is unable to meet cellular metabolic needs and oxygen consumption requirements.

2023年12月13日 · This topic will review the pathophysiologic determinants and classification of shock. The initial evaluation and management of shock in children, in general, and hypovolemic and septic shock, specifically, are discussed separately.

2024年11月21日 · Basic adrenergic receptor physiology and the principles, complications, and controversies surrounding use of vasopressors and inotropes for treatment of shock are presented here.

This topic will review the initial evaluation of children with shock and focus on the clinical features that identify and classify shock in resource-abundant settings and can be used to evaluate response to treatment.

This page provides comprehensive information on Pediatric Advanced Life Support (PALS) for critically ill pediatric patients.

2024年5月16日 · While patients often have a combination of more than one form of shock (multifactorial shock), four classes of shock are recognized (table 1): Distributive (eg, septic shock, systemic inflammatory response syndrome, neurogenic shock, anaphylactic shock, toxic shock, end-stage liver disease, endocrine shock)

2023年11月3日 · Secondary trauma from shock wave – Peak temperature within a bolt of lightning rises within milliseconds to 30,000 Kelvin (five times hotter than the sun), generating a shock wave of up to 20 atmospheres induced by the rapid heating of the surrounding air [9,25,29].

2022年9月16日 · This topic reviews intraoperative resuscitation and anesthetic management for patients with reversible causes of shock. Management of shock in other settings (eg, emergency department, intensive care unit) may overlap with the perioperative period, as discussed in separate topics:

2024年9月11日 · Interpreting hemodynamic data from PACs is important for the diagnosis and management of a range of conditions including shock and pulmonary artery hypertension (table 1).

2023年9月1日 · High-energy shocks are often programmed as the initial therapy for very fast rhythms (eg, more than 200 to 220 beats per minute), or as a rescue therapy if anti-tachycardia pacing fails.
