Surgical shock

[1] Cardiomyopathy is typically a chronic problem which occurs due to changes heart muscle that negatively affect function.

It may contribute to surgical shock as an underlying issue, such as the already weakened heart not being able to continue pumping blood effectively during or after the stress of surgery.

Blood clots are a common complication during and after surgery, sometimes leading to deep venous thrombosis and pulmonary embolism.

[4] Anaphylactic shock may occur in surgical settings due to use of a drug or material that a patient has previously developed an allergy toward.

Exposure to an allergen causes release of inflammatory chemicals like histamine, which lead to dysfunction of multiple organ systems and shock.

[6] Neurogenic shock occurs due to spinal cord injury, which leads to inability to balance signals from the autonomic nervous system to maintain ideal blood pressure and other vital signs.

Compensated shock requires fast identification and action by the medical team to prevent decompensation.

[3] In decompensated shock, a patient may experience confusion and/or loss of consciousness when their brain is not getting enough oxygen from blood flow.

[1][3] Each of these signs and symptoms act as clues to help medical providers understand and diagnose shock, allowing them to promptly treat the underlying cause.
