Cranial burr holes in the emergency department: to drill or not to drill?

Drainage of an extradural haematoma by intraosseous needle in a remote hospital

We report the case of an intraosseous needle used to drain an acute extra-dural haematoma in a remote hospital. An 18 yr. old female attended the Emergency Department, after sustaining a closed head injury from a fall. After a CT scan, she was diagnosed with a large acute extradural haematoma (EDH). Prior to air ambulance transfer to the Neurosurgical Centre, she developed a fixed dilated pupil and hemodynamic instability. The Neurosurgeon advised that an intraosseous (IO) needle drainage would prevent brain stem herniation. An Emergency Medicine (EM) consultant drained 60 ml of blood and clot via an IO needle. The pupil and cardiovascular status normalised. The patient underwent neurosurgical drainage with full neurological recovery. We believe that this is the first IO drainage of an EDH at a remote hospital followed by full neurological recovery.

Trepanations in the ancient Greek colony of Akanthos: Skull surgery in the light of Hippocratic medicine

OBJECTIVE

The study presents seven new cases of trepanations on four individuals from the ancient Greek colony of Akanthos (5th - 1st c. BC) and juxtaposes the paleopathological observations with the Hippocratic treatises.

MATERIALS

A meta-analysis of 42 published trepanations on 27 individuals from Greece.

METHODS

Trepanations from Akanthos were observed macroscopically, stereoscopically and by computer tomography. The meta-analysis considers the demographic, geographical and temporal distribution, the techniques, associated pathology, and survival rate.

RESULTS

Trepanations were observed on four females in Akanthos. Three trepanations were performed with scraping and four with drilling. Two individuals exhibited significant signs of healing, and two survived shortly after the operation. In two cases, trepanation was practiced for treating cranial injuries. In Greek antiquity trepanation was performed predominantly in males, principally as a surgical treatment of cranial injuries. The survival rate was 62.9 %. Scraping was the oldest, most frequent and successful technique.

CONCLUSIONS

Trepanation performed systematically in Greece since the Bronze Age (ca. 2,000 BC). Hippocrates who rationally conceived medicine, codified the pre-existing empirical knowledge. The trepanations from Akanthos show technical similarities but also discrepancies from the Hippocratic recommendations, confirming the mental and technical readiness of the ancient surgeon.

SIGNIFICANCE

The synchronous to Hippocrates trepanations from Akanthos, provide the opportunity to compare physical evidence with the written sources.

LIMITATIONS

The frequency of trepanations is affected by the representativeness and the state of the skeletal preservation.

SUGGESTIONS FOR FUTURE RESEARCH

Trepanations published in previous decades, need to be reassessed with new imaging modalities. A standard recording methodology is fundamental for data comparison.
