AbstractTherapeutic hypothermia favorably impacts neurologic outcomes in patients after cardiopulmonary arrest, although the appropriate target temperature is less clear. Its safety profile in patients with systemic sclerosis (SSc) and Raynaud phenomenon (RP), who may be at increased risk for ischemic complications, has not been addressed in the literature, to our knowledge. Digital lesions are commonly seen in patients with SSc, and cold-induced myocardial ischemia has also been reported. We describe a case of a man with SSc, RP, and digital ulcers who underwent therapeutic hypothermia after cardiopulmonary arrest. He regained full neurologic function, and except for digital necrosis, no hypothermia-associated adverse events were observed. Other risk factors for ischemia, such as cocaine use, may have contributed to the development of the digital necrosis. However, clinicians should be aware of the risk for ischemic complications in patients with SSc and RP when considering the appropriate target temperature after cardiopulmonary arrest.
