Existing studies have primarily employed two maintenance strategies using either intensive insulin therapy (IIT) (maintain glucose p = 0.628), ICU LOS (MD = -0.073 days, 95% CI = -0.324 to 0.178;p = 0.568), or hospital LOS (MD = 0.269, 95% CI = -2.158 to 2.696;p = 0.828). No difference in AF rates (RR = 0.887, 95% CI = 0.681 to 1.155;p = 0.375) or deep sternal infection (RR = 0.985, 95% CI = 0.357 to 2.720;p = 0.977) were observed. Conclusion: IIT targeting blood sugar levels of 80 - 120 mg/dl have no effect on perioperative outcomes in cardiac surgery patients. IIT is associated with similar mortality, ICU LOS, hospital LOS, AF rates, and deep sternal infection rates compared to more liberal glycemic strategies. IIT should not replace CIT as the standard of care in cardiac surgery patients.展开更多

Sixty-four cases of severe trauma (injury severity score 〉20) with stress hyperglycemia (blood glucose 〉9 mmol/L) were randomly divided into intensive insulin therapy group and conventional therapy group. ELISA method, radioimmunoassay and density gradient grada- tion one-step process were used to determine plasma VEGF, endothelin-1 (ET-1), and the number of circulating endothelial cells (CECs) at the day of 0, 2, 3, 5 and 7 after admission. Simultaneously, the changes of CRP concentration in plasma were monitored to evaluate inflammatory response. The results showed that plasma levels of observational indexes in patients receiving early-stage intensive insulin therapy were all significantly lower than those in conventional therapy groups 2, 3, 5 and 7 days after admission [for VEGF (ng/L), 122.2±23.8 vs. 135.9±26.5, 109.6±27.3 vs. 129.0±18.4, 88.7±18.2 vs. 102.6±27.3, 54.2±26.4 vs. 85.7±35.2, P〈0.05, 0.01, 0.05, 0.05 respectively; for ET-1 (ng/L), 162.8±23.5 vs. 173.7±13.2, 128.6±17.5 vs. 148.8±22.4, 96.5±14.8 vs. 125.7±14.8, 90.7±16.9 vs. 104.9±22.5, P〈0.05, 0.01, 0.01, 0.01 respectively; for CRP (mg/L), 23.2±13.8 vs. 31.9±16.5, 13.6±17.3 vs. 23.5±18.4, 8.7±10.2 vs. 15.6±13.3, 5.2±9.4 vs. 10.7±11.2, all P〈0.05; for CECs (/0.9 μL), 10.9±5.6 vs. 13.9±6.2, 8.5±4.9 vs. 11.3±5.3, 6.3±6.4 vs. 9.4±5.7, 4.8±7.1 vs. 7.8±4.8, all P〈0.05]. It was concluded that intensive insulin therapy could antagonize the endothelium injury after trauma and reduce inflammation response quickly, which was one of important mechanisms by which intensive insulin therapy improves the prognosis of trauma patients.展开更多

A total of 114 patients with traumatic shock combined with MODS were randomly divided into two groups: control group (n=56) treated with conventional therapy, and intensive insulin therapy group (n=58) treated with conventional therapy plus continuous insulin pumping to control the blood glucose level at range of 4.4-6.1 mmol/L. White blood cells (WBC) counts, prothrombin time (PT), serum creatinine (SCr), alanine aminotransferase (ALT), serum albumin and PaO2 were measured before and at the day 1, 3, 5, 7 and 14 after treatment. The incidence of gastrointestinal dysfunction, the incidence of MODS, hospital stay and the mortality were also observed and compared. After intensive insulin therapy, the WBC counts, SCr, ALT and PT were significantly reduced (P0.05), but the level of serum albumin was significantly increased (P0.05) at the day 3, 5, 7 and 14. In the meantime, the PaO2 was significantly elevated at the day 3, 5 and 7 (P0.01) after intensive insulin therapy. The incidence of gastrointestinal dysfunction, the incidence of MODS, the length of hospital stay and the mortality were markedly decreased (P0.01). The results suggest early treatment with intensive insulin therapy is effective for traumatic shock combined with MODS and can decrease the length of hospital stay and the mortality.展开更多

METHODS: Within 24 h of intensive care unit management, patients with gastric cancer were enrolled after written informed consent and randomized to the intensive insulin therapy (IIT) group to keep glucose levels from 4.4 to 6.1 mmol/L or the conventional insulin therapy (CIT) group to keep levels less than 10 mmol/L. Resting energy expenditure (REE), respiratory quotient (RQ), resting energy expenditure per kilogram (REE/kg), and the lipid oxidation rate were monitored by the indirect calorimeter of calcium citrate malate nutrition metabolism investigation system. The changes in body composition were analyzed by multi-frequency bioimpedance analysis. Blood fasting glucose and insulin concentration were measured for assessment of Homeostasis model assessment of insulin resistance. RESULTS: Sixty patients were enrolled. Compared with preoperative baseline, postoperative REE increased by over 22.15% and 11.07%; REE/kg rose up to 27.22 ± 1.33 kcal/kg and 24.72 ± 1.43 kcal/kg; RQ decreased to 0.759 ± 0.034 and 0.791 ± 0.037; the lipid oxidation ratio was up to 78.25% ± 17.74% and 67.13% ± 12.76% supported by parenteral nutrition solutions from 37.56% ± 11.64% at the baseline; the level of Ln-HOMA-IR went up dramatically (P < 0.05, respectively) on postoperative days 1 and 3 in the IIT group. Meanwhile the concentration of total protein, albumin and triglyceride declined significantly on postoperative days 1 and 3 compared with pre-operative levels (P < 0.05, respectively). Compared with the CIT group, IIT reduced the REE/kg level (27.22 ± 1.33 kcal/kg vs 29.97 ± 1.47 kcal/kg, P = 0.008; 24.72 ± 1.43 kcal/kg vs 25.66 ± 1.63 kcal/kg, P = 0.013); and decreased the Ln-HOMA-IR score (P = 0.019, 0.028) on postoperative days 1 and 3; IIT decreased the level of CRP on postoperative days 1 and 3 (P = 0.017, 0.006); the total protein and albumin concentrations in the IIT group were greater than those in the CIT group (P = 0.023, 0.009). Postoperative values of internal cell fluid (ICF), fat mass, protein mass (PM), muscle mass, free fat mass and body weight decreased obviously on postoperative 7th day compared with the preoperative baseline in the CIT group (P < 0.05, respectively). IIT reduced markedly consumption of fat mass, PM and ICF compared with CIT (P = 0.009 to 0.026). CONCLUSION: There were some benefits of IIT in decreasing the perioperative insulin resistance state, reducing energy expenditure and consumption of proteins and lipids tissue in patients undergoing gastrectomy.展开更多

Objective: This study evaluated the efficacy and safety of switching bolus insulin from insulin lispro (Lis) to insulin glulisine (Glu) in patients with inadequately controlled diabetes on intensive insulin therapy with Lis and glargine (Gla). Methods: Seventy-two outpatients with inadequate glycemic control (glycated hemoglobin [HbA1c] ≥7.0%, glycated albumin [GA] ≥20%) on intensive insulin therapy comprising Lis and Gla for ≥24 weeks were enrolled. We switched treatment from Lis to Glu with a stepwise increase in the dose by 1 unit per meal to obtain a GA level of ≤20% for 24 weeks, and the efficacy and safety were evaluated. Patients’ treatment satisfaction was also evaluated using the Diabetes Treatment Satisfaction Questionnaire (DTSQ) after the treatment. Results: After switching from Lis to Glu, both HbA1c and GA levels significantly lowered from 8.26% ± 0.13% to 7.71% ± 0.13% (P < 0.01) and from 23.9% ± 1.8% to 21.4% ± 1.9% (P < 0.01), respectively. Furthermore, switching from Lis to Glu improved patients’ treatment satisfaction;scores for 7 of the 8 items, such as “satisfaction” and “convenience” were significantly improved (P < 0.001), with no significant change in the scores for “improvement of hypoglycemia” (P = 0.91). Conclusions: Our present study suggests that switching bolus insulin from Lis to Glu by the addition of 1 unit of Glu per meal may be a useful treatment option for patients with inadequate glycemic control receiving intensive insulin therapy with Lis and Gla.展开更多

Short acting insulin analogues(SAIA) have been synthesized to improve the chronic treatment of patients with diabetes but, because of the pharmacokinetic characteristics that include shorter onset and off-set, they can be effectively used also in ICU patients and have the potential to be associated with a more limited risk of inducing episodes of iatrogenic hypoglycemia. Medical therapies carry an intrinsic risk for collateral effects; this can be more harmful in patients with unstable clinical conditions like ICU patients. To minimize these risks, the use of short acting drugs in ICU patients have gained a progressively larger room in ICU and now pharmaceutical companies and researchers design drugs dedicated to this subset of medical practice. In this article we report the rationale of using short acting drugs in ICU patients(i.e., sedation and treatment of arterial hypertension) and we also describe SAIA and their therapeutic use in ICU with the potential to minimize iatrogenic hypoglycemia relatedto IIT. The pharmacodynamic and pharmachokinetic characteristics of SAIA will be also discussed.展开更多

It is well known that hyperglycemia induced by surgical stress often results in dysregulation of liver metabolism and immune function, impairing postoperative recovery. Current evidence suggests that maintaining normoglycemia postoperatively improves surgical outcome and reduces the mortality and morbidity of critically ill patients. On the basis of these observations, several large randomized controlled studies were designed to evaluate the benefit of postoperative tight glycemic control with intensive insulin therapy. However, intensive insulin therapy carries the risk of hypoglycemia, which is linked to serious neurological events. Recently, we demonstrated that perioperative tight glycemic control in surgical patients could be achieved safely using a closed-loop glycemic control system and that this decreased both the incidence of infection at the site of the surgical incision, without the appearance of hypoglycemia, and actual hospital costs. Here, we review the benefits and requirements of perioperative intensive insulin therapy using a dosed-loop artificial endocrine pancreas system in hepatectomized patients. This novel intensive insulin therapy is safe and effectively improves surgical outcome after hepatic resection.展开更多

If managed inadequate...Blood glucose control, including hyperglycemia correction, maintaining glucose at optimal level and avoiding hypoglycemia, is a challenge clinicians face every day in intensive care units (ICUs). If managed inadequately, its related mortality can increase. Prior to 2001, no relevant data from randomized, controlled studies assessing glucose control in the ICU were available. In the past 18 years, however, many clinical trials have defined criteria for managing abnormal blood glucose levels, as well as provided suggestions for glycemic monitoring. Point-ofcare blood glucose monitors have become the preferred bedside technology to aid in glycemic management. In addition, in some institutions, continuous glucose monitoring is now available. Cost-effectiveness of adequate glycemic control in the ICU must be taken into consideration when addressing this complex issue. Newer types of glycemic monitoring may reduce nursing staff fatigue and shorten times for the treatment of hyperglycemia or hypoglycemia. There are a variety of glycemic care protocols available. However, not all ICU clinicians are aware of them. The following minireview describes some of these concepts.展开更多

文摘The therapeutic effects of intensive insulin therapy in treatment of traumatic shock combined with multiple organ dysfunction syndrome (MODS) were investigated. A total of 114 patients with traumatic shock combined with MODS were randomly divided into two groups: control group (n=56) treated with conventional therapy, and intensive insulin therapy group (n=58) treated with conventional therapy plus continuous insulin pumping to control the blood glucose level at range of 4.4-6.1 mmol/L. White blood cells (WBC) counts, prothrombin time (PT), serum creatinine (SCr), alanine aminotransferase (ALT), serum albumin and PaO2 were measured before and at the day 1, 3, 5, 7 and 14 after treatment. The incidence of gastrointestinal dysfunction, the incidence of MODS, hospital stay and the mortality were also observed and compared. After intensive insulin therapy, the WBC counts, SCr, ALT and PT were significantly reduced (P0.05), but the level of serum albumin was significantly increased (P0.05) at the day 3, 5, 7 and 14. In the meantime, the PaO2 was significantly elevated at the day 3, 5 and 7 (P0.01) after intensive insulin therapy. The incidence of gastrointestinal dysfunction, the incidence of MODS, the length of hospital stay and the mortality were markedly decreased (P0.01). The results suggest early treatment with intensive insulin therapy is effective for traumatic shock combined with MODS and can decrease the length of hospital stay and the mortality.

文摘AIM: To investigate the effect of intensive vs conventional insulin therapy on perioperative nutritional substrates metabolism in patients undergoing radical distal gastrectomy. METHODS: Within 24 h of intensive care unit management, patients with gastric cancer were enrolled after written informed consent and randomized to the intensive insulin therapy (IIT) group to keep glucose levels from 4.4 to 6.1 mmol/L or the conventional insulin therapy (CIT) group to keep levels less than 10 mmol/L.

Meanwhile the concentration of total protein, albumin and triglyceride declined significantly on postoperative days 1 and 3 compared with pre-operative levels (P < 0.05, respectively). Compared with the CIT group, IIT reduced the REE/kg level (27.22 ± 1.33 kcal/kg vs 29.97 ± 1.47 kcal/kg, P = 0.008; 24.72 ± 1.43 kcal/kg vs 25.66 ± 1.63 kcal/kg, P = 0.013); and decreased the Ln-HOMA-IR score (P = 0.019, 0.028) on postoperative days 1 and 3; IIT decreased the level of CRP on postoperative days 1 and 3 (P = 0.017, 0.006); the total protein and albumin concentrations in the IIT group were greater than those in the CIT group (P = 0.023, 0.009). Postoperative values of internal cell fluid (ICF), fat mass, protein mass (PM), muscle mass, free fat mass and body weight decreased obviously on postoperative 7th day compared with the preoperative baseline in the CIT group (P < 0.05, respectively). IIT reduced markedly consumption of fat mass, PM and ICF compared with CIT (P = 0.009 to 0.026).

文摘Blood glucose control in intensive care unit(ICU) patients, addressed to actively maintain blood glucose concentration within defined thresholds, is based on two major therapeutic interventions: to supply an adequate calories load and, when necessary, to continuously infuse insulin titrated to patients needs: intensive insulin therapy(IIT). Short acting insulin analogues(SAIA) have been synthesized to improve the chronic treatment of patients with diabetes but, because of the pharmacokinetic characteristics that include shorter onset and off-set, they can be effectively used also in ICU patients and have the potential to be associated with a more limited risk of inducing episodes of iatrogenic hypoglycemia. Medical therapies carry an intrinsic risk for collateral effects; this can be more harmful in patients with unstable clinical conditions like ICU patients. To minimize these risks, the use of short acting drugs in ICU patients have gained a progressively larger room in ICU and now pharmaceutical companies and researchers design drugs dedicated to this subset of medical practice. In this article we report the rationale of using short acting drugs in ICU patients(i.e., sedation and treatment of arterial hypertension) and we also describe SAIA and their therapeutic use in ICU with the potential to minimize iatrogenic hypoglycemia relatedto IIT. The pharmacodynamic and pharmachokinetic characteristics of SAIA will be also discussed.
文摘Postoperative hyperglycemia is common in critically ill patients, even in those without a prior history of diabetes mellitus. It is well known that hyperglycemia induced by surgical stress often results in dysregulation of liver metabolism and immune function, impairing postoperative recovery. Current evidence suggests that maintaining normoglycemia postoperatively improves surgical outcome and reduces the mortality and morbidity of critically ill patients. On the basis of these observations, several large randomized controlled studies were designed to evaluate the benefit of postoperative tight glycemic control with intensive insulin therapy. However, intensive insulin therapy carries the risk of hypoglycemia, which is linked to serious neurological events. Recently, we demonstrated that perioperative tight glycemic control in surgical patients could be achieved safely using a closed-loop glycemic control system and that this decreased both the incidence of infection at the site of the surgical incision, without the appearance of hypoglycemia, and actual hospital costs. Here, we review the benefits and requirements of perioperative intensive insulin therapy using a dosed-loop artificial endocrine pancreas system in hepatectomized patients. This novel intensive insulin therapy is safe and effectively improves surgical outcome after hepatic resection.

文摘AIM:To evaluate the impact on glucose variability(GLUCV)of an nurse-implemented insulin infusion protocol when compared with a conventional insulin treatment during the day-to-day clinical activity.METHODS:We enrolled 44 type 2 diabetic patients(n=32 males;n=12 females)with acute coronary syndrome(ACS)and randomy assigned to standard a subcutaneous insulin treatment(n=23)or a nurse-implemented continuous intravenous insulin infusion protocol(n=21).We utilized some parameters of GLUCV representing well-known surrogate markers of prognosis,i.e.,glucose standard deviation(SD),the mean dailyδglucose(mean of daily difference between maximum and minimum glucose),and the coefficient of variation(CV)of glucose,expressed as percent glucose(SD)/glu-cose(mean).RESULTS:At the admission,first fasting blood glucose,pharmacological treatments(insulin and/or anti-diabetic drugs)prior to entering the study and basal glycated hemoglobin(HbA1c)were observed in the two groups treated with subcutaneous or intravenous insulin infusion,respectively.When compared with patients submitted to standard therapy,insulin-infused patients showed both increased first 24-h(median 6.9 mmol/L vs 5.7mmol/L P<0.045)and overall hospitalizationδglucose(median 10.9 mmol/L vs 9.3 mmol/L,P<0.028),with a tendency to a significant increase in first 24-h glycaemic CV(23.1%vs 19.6%,P<0.053).Severe hypoglycaemia was rare(14.3%),and it was observed only in 3 patients receiving insulin infusion therapy.HbA1c values measured during hospitalization and 3 mo after discharge did not differ in the two groups of treatment.CONCLUSION:Our pilot data suggest that no real benefit in terms of GLUCV is observed when routinely managing blood glucose by insulin infusion therapy in type 2 diabetic ACS hospitalized patients in respect to conventional insulin
文摘Blood glucose control, including hyperglycemia correction, maintaining glucose at optimal level and avoiding hypoglycemia, is a challenge clinicians face every day in intensive care units (ICUs). If managed inadequately, its related mortality can increase. Prior to 2001, no relevant data from randomized, controlled studies assessing glucose control in the ICU were available. In the past 18 years, however, many clinical trials have defined criteria for managing abnormal blood glucose levels, as well as provided suggestions for glycemic monitoring. Point-ofcare blood glucose monitors have become the preferred bedside technology to aid in glycemic management. In addition, in some institutions, continuous glucose monitoring is now available. Cost-effectiveness of adequate glycemic control in the ICU must be taken into consideration when addressing this complex issue. Newer types of glycemic monitoring may reduce nursing staff fatigue and shorten times for the treatment of hyperglycemia or hypoglycemia. There are a variety of glycemic care protocols available. However, not all ICU clinicians are aware of them. The following minireview describes some of these concepts.
文摘Background Intensive insulin therapy has been found to lessen the progress of diabetic retinopathy (DR) to some extent,while it has also been implicated to be responsible for decrease of DR.We investigated visual function and morphological changes in the macular area in short-term follow-up of patients with type 2 diabetes mellitus after intensive insulin therapy.Methods This was a prospective clinical study of nonproliferative DR patients (102 eyes,120 patients) undergoing intensive insulin therapy.The Contrast Glare Tester (Takagi CGT-1000) was used to examine contrast sensitivity (CS) and Heidelberg Retina Tomograph (HRT) Ⅱ and Stratus Model 3000 OCT were used to observe the changes of morphology in the macular area.Follow-up times were pre-intensive therapy,3 and 6 months post-intensive therapy.Results CS at low and middle frequencies was higher at 3 and 6 months post-therapy compared with pre-therapy (P 〈0.05).Significant differences in CS at low frequency were found between 6 and 3 months post-therapy (P 〈0.05).Macular edema index was lower in the first,second,and third rings of the macular area after intensive therapy compared with pre-therapy (P 〈0.05).Compared with 3 months post-therapy,the macular edema index was lower in the first,second,and third rings of the macular area at 6 months post-therapy (P 〉0.05).No significant differences in the thickness of the first,second,and third rings of the macular area were detected between 3 and 6 months post-therapy and pre-therapy (P〉0.05).Conclusion CS and macular edema indexes were significantly improved in nonproliferative diabetic retinopathy patients after intensive insulin therapy,but thickness of the macular area was unchanged.
