Blood transfusion and resuscitation using penile corpora: an experimental study

Area of Science:

• Urology
• Emergency Medicine
• Transfusion Medicine

Background:

• Establishing reliable venous access for blood transfusion and resuscitation is critical in emergency medicine.
• The penile corpora cavernosa represent an underutilized anatomical space with potential for rapid fluid administration.

Purpose of the Study:

• To evaluate the feasibility, safety, and efficacy of using the penile corpora cavernosa for autologous blood transfusion and resuscitation.

Main Methods:

• Autologous blood transfusion into the corpora cavernosa was performed in three male donkeys.
• Hemorrhagic shock was induced in three dogs, followed by blood transfusion into their corpora cavernosa.
• Transfusion rates, access time, and adverse effects were assessed in both models.

Main Results:

• Transfusion into the corpora cavernosa was achieved rapidly (mean access time 22 seconds in donkeys, mean transfusion rate 31.7-35.2 mL/min).
• No significant adverse events like extravasation or hematoma were observed.
• All shocked dogs were successfully resuscitated following transfusion.

Conclusions:

• The penile corpora cavernosa provide a feasible, simple, rapid, and effective alternative route for blood transfusion and venous access.
• This method is a reliable option for volume replacement and resuscitation in males when conventional routes are unavailable or insufficient.
