When people talk about the “Crile method”, they may mean one of several ideas developed by Dr George Crile in the early 1900s. Each one aimed at the same goal: getting patients through surgery safely.
1. Measuring blood pressure during surgery
Crile was among the first surgeons to treat blood pressure as a vital sign during operations. His research, published in Blood Pressure in Surgery (1903), showed how pressure falls in shock. Today, monitoring blood pressure in theatre is routine.
2. Direct blood transfusion
Before blood could be stored, transfusion had to go directly from donor to patient. Crile developed a method of joining the donor’s artery to the patient’s vein using a small cannula, so blood flowed straight across. It was difficult and slow, but it saved lives and paved the way for modern transfusion.
3. Anoci-association: “shockless” surgery
Crile believed that fear, pain and nerve signals from the surgical site all added to shock. His method combined:
- Calming the patient before surgery
- Light general anaesthesia
- Local anaesthetic to block nerves in the operative area
He described this in his book Anoci-Association (1914). The idea of combining general and local anaesthesia is still used today.
4. Careful control of bleeding
Losing less blood meant less shock. Crile’s work went hand in hand with careful hemostasis, the control of bleeding with clamps and ties. The Crile forceps is part of this legacy.
What surgery still uses today
| Crile’s idea | Modern practice |
|---|---|
| Blood pressure in surgery | Continuous monitoring in every theatre |
| Direct transfusion | Blood banks and modern transfusion |
| Anoci-association | Combined general and regional anaesthesia |
| Careful hemostasis | Hemostatic forceps, ties and energy devices |
