The immediate constitutional effects of surgical injuries and operations are produced in one of three ways: (1) by direct injury to vital organs; (2) by loss of blood; and (3) by shock. Symptoms due to paralysis of the vaso-motor centers may be caused by an injury or emotional disturbance, leading to collapse. The intensity of shock depends on the nature and severity of the injury, while resulting collapse varies with the instability of nerve centers. Children, nervous women, and old persons show effects more markedly than robust men. Shock symptoms are instantaneous but can deepen over time due to progressive loss of blood. Cases of deferred shock occur where intense emotions inhibit initial shock response or when a delayed emotional reaction causes collapse after physical injury.
<Callout type="important" title="Critical for Diagnosis">Understanding the difference between shock and collapse is crucial for proper diagnosis and treatment.</Callout>
Every injury produces some degree of shock, leading to varying degrees of collapse from slight disturbances to instant death. Symptoms vary based on whether they are due to direct injury, shock, or hemorrhage. Recent injuries may be associated with conditions like apoplexy, epilepsy, and alcoholism, complicating diagnosis.

The chapter concludes by discussing secondary constitutional effects such as reaction, fever, fat-embolism, thrombosis, delirium tremens, tetanus, hydrophobia, and collapse. It also covers surgical fevers due to toxins from organisms or non-infective causes.
Key Takeaways
- Shock and collapse are immediate constitutional effects of surgical injuries, varying in severity based on injury type and patient condition.
- Symptoms due to shock can be confused with those from direct injury or hemorrhage, complicating diagnosis.
- Secondary complications such as fat-embolism and thrombosis may occur after initial injury.
Practical Tips
- Always assess the immediate effects of an injury for signs of shock or collapse.
- Monitor vital signs closely to distinguish between different causes of constitutional effects.
- Be prepared to address secondary complications that arise from primary injuries.
Warnings & Risks
- Misdiagnosis can lead to improper treatment and worsening patient condition.
- Secondary complications like fat-embolism may occur even after initial symptoms have subsided.
Modern Application
While the diagnostic methods described here are outdated, understanding the principles of shock and collapse remains crucial for modern emergency responders. The detailed descriptions of symptom progression and differential diagnosis provide a solid foundation for recognizing these conditions in contemporary settings.
Frequently Asked Questions
Q: What are the three main causes of constitutional effects after surgical injuries?
The three main causes are direct injury to vital organs, loss of blood, and shock. Each can lead to varying degrees of collapse depending on the severity and nature of the injury.
Q: How does emotional disturbance contribute to symptoms similar to those caused by physical injury?
Emotional disturbances like fear or rage can cause paralysis of vaso-motor centers in the medulla, leading to symptoms that mimic those from direct injuries. This is often referred to as shock.
Q: What distinguishes traumatic fever from septicemia in surgical fevers?
Traumatic fever arises early after injury with slight intensity and subsides within 48-72 hours, while septicemia involves living infective organisms in the blood along with their toxins.
