Renal Data from Asia-Africa: Spectrum of intradialytic complications during hemodialysis and its management: a single-center experience

Hemodialysis (HD) is one of the important modalities of renal replacement therapy in acute renal failure (ARF) as well as chronic renal failure (CRF). This study was performed to evaluate the various intradialytic complications that occur during HD and their management. This is a retrospective study performed in patients who underwent conventional HD during the period of 1 January 2000 to 31 December 2011 at our center. Clinical details,various complications faced and their management were retrieved from dialysis case sheets. A total of 2325 patients of renal failure (790 ARF and 1535 CRF patients) were assessed for the intradialytic complications of HD. During the study period,there were 12,785 bicarbonate dialyses performed on these patients. In the ARF patients,the common intradialytic complications were: Hypotension,seen in 1296 sessions (30.4%),nausea and vomiting seen in 1125 sessions (26.4%),fever and chills seen in 818 sessions (19.2%),headache seen in 665 sessions (15.6%),cramps seen in 85 sessions (2.0%),chest pain and back pain seen in 82 sessions (1.92%),hypoglycemia seen in 77 sessions (1.8%),first-use syndrome seen in 72 sessions (1.7%) and femoral hematoma seen in 31 sessions (0.73%). In the CRF group,common complications were hypotension in 2230 sessions (26.1%),nausea and vomiting in 1211 sessions (14.2%),fever and chills in 1228 sessions (14.4%),chest pain and back pain in 1108 cases (13.0%),hypertension in 886 sessions (10.4%),headache in 886 sessions (10.4%),cramps in 256 sessions (3.0%),hematoma in 55 sessions (0.64%),intracerebral hemorrhage in three sessions (0.03%) and catheter tip migration in three sessions (0.03%). There is a need for special attention for the diagnosis and management of intradialytic complications of HD because such complications could be managed successfully without the need for termination of the dialysis procedure.
