RT - Journal Article T1 - When Nerves Fail: A Cause of Respiratory failure in a Diabetic Patient JF - babol-caspjim YR - 2022 JO - babol-caspjim VO - 13 IS - 2 UR - http://caspjim.com/article-1-2173-en.html SP - 436 EP - 438 K1 - Diabetic neuropathy K1 - bilateral diabetic phrenic neuropathy K1 - diaphragmatic paresis. AB - Background: Respiratory failure secondary to bilateral diabetic phrenic neuropathy is an uncommon clinical scenario. It is challenging to treat and often results in the need for long-term respiratory support. Case Presentation: We report a patient with long standing diabetes mellitus (DM) who presented with respiratory failure requiring mechanical ventilation. He was subsequently found to have reduced phrenic nerve and diaphragm compound action potential amplitude bilaterally on nerve conduction studies. Conclusion: Diabetic patients with unexplained shortness of breath should raise suspicion for diaphragmatic paresis from phrenic neuropathy.
