BackgroundDiabetic ketoacidosis (DKA) is a life-threatening condition as a complication of diabetes and represents a significant healthcare global burden. The current study goal was to determine factors affecting time to recovery from DKA in Alexandria Main University Hospital.Patients and methodsOne hundred fifty patients who had been admitted with DKA were included in this study. All patients were managed with hospitalization for IV fluids, continuous intravenous insulin infusion, electrolyte correction, as well as detection and treatment of the predisposing factor until the full resolution of DKA.ResultsMales contributed to 58.7% of the total patients in this study with a mean age of 32.16 ± 15.06 years. DKA mean time of resolution was 18.76 ± 14.07 h. The majority of patients were with T1DM (86%), while T2DM were 14%. Missed insulin dose was the leading precipitating factor (60.7%) followed by infections (38.7%). There was a statistically significant relationship between DKA resolution time with age, time of presentation, type of diabetes, initial pH, initial serum K+ level, initial HCO3− level, initial anion gap, initial base excess, and initial RBS (p value < 0.001).ConclusionDelayed time of resolution from DKA was associated with initial lower pH, initial lower HCO3− level, initial lower base excess level, initial higher anion gap level, type 2 diabetes mellitus, patients on pre-mixed insulin regimen, old patients, delayed time for seeking medical care, and abnormal serum K+ level.
