Palliative Use of Nitroglycerin to Improve Microvascular Circulation.

Background: In the setting of critical illness, life preservation may come at the expense of limb as increasing concentration of vasopressors causes peripheral ischemia. When goals of care specify comfort measures, clinicians are faced with the difficult task of mitigating already present distal malperfusion while abiding to wishes of patient and patients' families. Physical changes post vasopressor use, such as mottling of appendages or cooling of skin, can limit meaningful physical interactions with grieving family members.

Case Presentation: We describe a case series of successful utilization of intravenous nitroglycerin to improve postvasopressor digital ischemia for comfort care measures to assist patient's families in the grieving process.

Conclusion: Following decision for comfort care measures, management for patient care goes beyond the realm of pain control. Dignified dying is an active process that requires clinicians to navigate care for both patient and patients' families. By reversing the digital ischemia associated with vasopressors, patients' families have the opportunity to give meaningful touch in setting of which it may be needed most.
