Rapid fixation of brains: a viable alternative?

Area of Science:

• Neuropathology
• Forensic Pathology
• Medical Practices

Background:

• Postmortem practices have evolved due to recent events, impacting necropsy procedures.
• Concerns from bereaved families regarding organ retention have led to changes in brain examination protocols.
• Aberdeen Royal Infirmary implemented a rapid brain fixation protocol in 2001 to address these concerns.

Purpose of the Study:

• To compare the efficacy of a new rapid brain fixation method with the conventional protocol.
• To evaluate the impact of rapid fixation on neuropathological examination quality.
• To assess the suitability of rapid fixation for diagnostic purposes.

Main Methods:

• A retrospective audit comparing brains fixed using the conventional protocol (1998) and the new rapid fixation method (2001).
• Random selection of an equal number of postmortem brains for both groups.
• A three-tier scoring system was used by a single observer to assess section and staining quality.

Main Results:

• No statistically significant difference in section and staining quality between rapid and conventional fixation methods.
• The rapid fixation method was found to be more frequently adequate for diagnosis.
• The new protocol facilitates the return of the brain to the body without undue delay.

Conclusions:

• Rapid brain fixation is a viable alternative for detailed neuropathological examination during necropsy.
• This method allows for thorough examination without unnecessarily prolonging organ retention.
• The findings support the adoption of rapid fixation techniques in medicolegal and hospital settings.
