What Researchers Did
Researchers documented 14 cases of women who developed severe blood flow problems in their limbs due to taking ergotamine for migraine headaches.
What They Found
The study found that 14 women experienced severe ischaemia in their limbs after taking varying doses of ergotamine tartrate for migraine. Ten of these patients had previously shown signs of ergotism, but only eight were initially diagnosed with it upon admission. Early in the study period, hyperbaric oxygen at 3 ATA was used as a standard treatment, later replaced by continuous intravenous nitroglycerine infusion.

Study Limitations
This study is a retrospective case series involving a small number of patients, which limits the ability to generalize its findings to a broader population.
