Animal products in neurosurgery - navigating informed consent

Area of Science:

• Neurosurgery
• Bioethics
• Medical Materials Science

Background:

• Informed consent is a critical ethical and legal standard in surgery.
• Advances in neurosurgery increasingly utilize animal-derived products.
• Disclosure of these materials is essential for patient autonomy.

Purpose of the Study:

• To identify common animal-derived products in neurosurgery.
• To aid neurosurgeons in discussing these products with patients.
• To support informed consent and shared decision-making.

Main Methods:

• Review of commonly used neurosurgical products containing animal-derived constituents.
• Analysis of manufacturer instructions and FDA documentation.
• Categorization of products into haemostatic agents, dural substitutes, sealants, and bone cements.

Main Results:

• Several categories of neurosurgical adjuncts contain animal or human-derived materials.
• Product information is available through manufacturer data and regulatory documents.
• Patient beliefs regarding animal products vary significantly across diverse populations.

Conclusions:

• Neurosurgeons must be aware of animal-derived components in surgical adjuncts.
• Individual patient beliefs and concerns regarding animal-derived products must be addressed.
• Tailored discussions and offering alternatives are crucial for ethical neurosurgical practice.
