Field block for cranial surgery in World War II

During World War II, physicians with minimal training were often thrust into the role of anesthetist. To educate these men, experts in anesthesia taught simple, conservative, and effective anesthetic techniques, such as the field block. Field blocks are the ideal "no frills" anesthetic because they are low-risk procedures that require minimal equipment. Unfortunately, many of the field blocks used during World War II are no longer taught. We present one technique that has fallen from favor, the field block for cranial surgery, both to educate about anesthesiology during World War II and to provide knowledge for the practicing military physician. The modern military anesthesiologist must be capable of anesthetizing patients under any conditions. First response care teams may find the technique of field block for cranial surgery useful in providing emergency anesthesia care.
