Abstract
Background: Hemodialysis treatment for acute kidney injury associated with crush syndrome is very complex. In our study, we summarized the problems and complications experienced by our hemodialysis center after the Kahramanmaraş earthquake. Methods: After the earthquake, our hospital treated 1396 victims. We evaluated the initial indications for dialysis, hemodialysis complications and the mortality of patients undergoing hemodialysis, including crush-related acute kidney injury (n = 82), during the earthquake period. We also compared them with patients who were undergoing hemodialysis (n = 76) in the same period but had end-stage renal failure and acute kidney injury due to other causes (n = 15). Results: After the earthquake, 173 adult patients, 91 (52.6%) of whom were male, with a mean age of 49.5 + 19.7 years, underwent hemodialysis between 6 and 22 February 2023. Patients with crush-related acute kidney injury experienced more complications during hemodialysis, and the increase in creatine kinase activity increased the risk of hemodialysis complications. The most common complications were blood clots in the dialyzer membrane, intradialytic hypotension, and intradialytic insufficient flow. The most frequent indication for initial hemodialysis was hyperkalemia (61, 74.4%). The major problems in the hemodialysis center included inadequate equipment and an insufficient number of experienced health personnel. Conclusions: Hyperkalemia is the most important initial indication for hemodialysis in patients with crush-related acute kidney injury. Crush-related acute kidney injury patients require hemodialysis more frequently, and hemodialysis complications are higher in patients with crush-related AKI, so the hemodialysis treatment of these patients should be more cautious. In an earthquake, hemodialysis centers may face significant challenges, such as damage, transportation issues, power outages, and water outages, which can hinder hemodialysis treatment.
