OBJECTIVE: To investigate the effects of plasma exchange (PE) combined with intensive insulin glycemic control on related indexes of patients with HLP. METHODS: A total of 120 HLP patients were randomly divided into control group (60 cases) and observation group (60 cases). Based on routine treatment, 2 groups were given PE treatment for 3 times+Low molecular weight heparin calcium for injection 5 000 U subcutaneously+Methylprednisolone sodium succinate for injection 40 mg intravenously+Calcium gluconate injection 2 g intravenously. Based on it, Insulin injection was pumped to random blood glucose <12 mmol/L with a micro-infusion pump in control group when random blood glucose concentration was equal to or more than 12 mmol/L. When random blood glucose of patients in observation group were higher than 8.3 mmol/L, Insulin injection was pumped with a micro-infusion pump for a week and random blood glucose concentration was maintained at 6.1-8.3 mmol/L. Plasma levels of triglyceride, PCT, WBC count, APACHEⅡ score, Balthazar CT score, length of hospitalization stay in ICU and the occurrence of ADR were observed in 2 groups before and after treatment. RESULTS: After treatment, plasma levels of triglyceride, amylase and PCT, WBC count, APACHEⅡ score and Balthazar CT score in 2 groups were significantly lower than before treatment, and the observation group was significantly lower than the control group, with statistical significance(P<0.05). Length of hospitalization stay in ICU observation group was significantly shorter than control group, with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS: PE combined with intensive insulin glycemic control can effectively reduce the level of plasma triglyceride,relieve inflammatory reaction and improve prognosis without increasing the occurrence of ADR.
