The effects of Ahmadi continuous nursing model in children with diabetic ketoacidosis were investigated in this study. A total of 120 children with diabetic ketoacidosis (DKA) were enrolled by convenience sampling from May 2018 to February 2022. Patients were equally divided into a control group and an observation group by a random number table. The control group received the routine continuous nursing model, while the observation group additionally received the Ahmadi continuous nursing model. The indicators of clinical first aid, level of blood glucose, insulin resistance, blood levels of sodium and potassium, family functioning and nursing satisfaction were compared before and after nursing in the two groups. Children in observation group had significantly shorter correction time of acidosis, blood pH recovery, urinary ketone negative and correction of electrolyte disturbance than those in the control group. The levels of fasting blood glucose (FBG), 2-hour postprandial blood glucose (2 hPG) and glycosylated hemoglobin (HbA1c) of children in the observation group were significantly lower than those in the control group. They also showed higher homeostasis model assessment-β (HOMA-β), less homeostasis model assessment-insulin resistance (HOMA-IR), and higher blood levels of sodium and potassium than those in the control group. The observation group scored higher on family adaptability and cohesion evaluation scales (FACESⅡ-CV) than the control group. Nursing satisfaction in the observation group was 96.7%, higher than that in the control group at 85%. Therefore, the Ahmadi continuous nursing model can effectively reduce the glycemic index, improve insulin resistance, correct the imbalance of blood levels of sodium and potassium, and improve family function and nursing satisfaction in children with DKA.
