Objective To investigate the effects of tight blood glucose control on the shortterm prognosis of the patients after heart valve replacement, in order to improve treatment effectiveness and lower postoperative complications. Methods A total of 240 patients including 150 males and 90 females underwent mitral valve replacement or mitral and aortic valve replacement were enrolled in this study from January 2007 to December 2008 at the cardiac surgery department of Renmin hospital of Wuhan university. The age of these patients ranged from 19 to 65 years old with an average age of 53.33 years. According to insulin administration time and blood glucose control level, they were randomly separated into two groups. In the experimental group, there were 121 patients who received continuous insulin infusion to maintain postoperative glucose level between 4.4 and 6.1 mmol/L, while 119 patients in the control group received insulin infusion when their glucose level went higher than 11.1 mmol/L to control the level between 6.1 and 11.1 mmol/L. Then the postoperative wound infection, malignant arrhythmia rate, the assisted ventilation time, intensive care unit(ICU) stay time and count of neutrophils were compared and analyzed. Results There was no hospitalized death in both groups. The rate of wound infection（3.31% vs.10.08%, χ2=4.430,P=0.035）, the assisted ventilation time（9.02±2.73 h vs. 10.01±3.58 h, t=2.280,P=0.024）, time for count of leukocytes to decrease to the normal level（11.04±3.16 d vs. 12.05±3.76 d, t=2.168,P=0.031）, average hospitalization time（13.49±3.81 d vs. 14.51±4.02 d,t=2.017,P=0.045）, and count of neutrophils on the third day（0.82±0.04 vs. 0.84±0.05, t=2.644,P=0.009） in the experimental group were significantly lower or shorter than those in the control group. But there was no significant difference between both groups in ICU stay time and the rate of malignant arrhythmia. Conclusion Tight blood glucose control can lower the rate of postoperative wound infection, shorten the assisted ventilation time and hospitalization time, and reduce the usage of antibiotics in patients after heart valve replacement. Accordingly, it can enhance the curative effect, reduce overall medical expenses, and improve prognosis.
Objective To evaluate clinical effects of strict control vs. conventional control of blood glucose in perioperative cardiac surgery. Methods Databases including PubMed, EMbase, HighWire, The Cochrane Library, CBM and VIP were searched to collect the randomized controlled trials (RCTs) on strict control vs. conventional control of blood glucose in perioperative cardiac surgery, published from 2000 to 2011. Two reviewers independently screened articles according to the inclusion and exclusion criteria, extracted data, and assessed quality of the included studies. Then meta-analysis was performed using RevMan 5.1. Results A total of 8 RCTs involving 2 250 patients were included. The results of meta-analysis showed that compared with the conventional group, the strict control of blood glucose could reduce postoperative short-term mortality (OR=0.52, 95% CI 0.30 to 0.91, P=0.02) and postoperative incidence rate of both atrial fibrillation (OR=0.64, 95%CI 0.43 to 0.96, P=0.03) and incision infection (OR=0.30, 95%CI 0.15 to 0.57, P=0.000 2), and shorten hospital stay (MD=1.75, 95%CI –3.18 to –0.32, Plt;0.02) and time of mechanical ventilation (MD=–0.9, 95%CI –1.43 to –0.38, Plt;0.000 8). Conclusion Current evidence shows that the strict control of blood glucose in perioperative cardiac surgery can reduce postoperative short-term mortality and postoperative incidence rate of both atrial fibrillation and incision infection, shorten hospital stay and time of mechanical ventilation, and have important clinical values and social and economic significance. However, this conclusion has to be proved by more high-quality and large-scale RCTs for the limitation of quantity and quality of the included studies.
ObjectiveTo investigate the epidemiological characteristics and predisposing causes of diabetic foot ulcer (DFU) in the hospitalized patients with diabetic foot disease (DFD).MethodsThe clinical data of patients with DFD admitted to West China Hospital of Sichuan University between January 1st, 2012 and December 31st, 2018 were collected through the electronic medical record system. The demographic characteristics, blood glucose control status, and the predisposing causes of DFU were analyzed.ResultsA total of 1 022 DFD inpatients with an average age of (65.5±11.9) years old were included in this study, including 679 males and 343 females; 59.4% (513/864) of the patients had a college degree or above, but the patients with more severe DFD had lower educational level (χ2trend=19.554, P<0.001). The average time from diagnosis of diabetes mellitus to occurrence of DFD was (10.6±7.1) years, and 42.4% (433/1 022) of the patients had diabetes for over 10 years. Among the patients, 82.3% (841/1 022) treated diabetes irregularly, 56.2% (555/987) never monitored blood glucose, 51.2% (523/1 022) had a history of foot ulcers, and 8.6% (88/1 022) had a history of lower extremity or toe amputation. The average fasting blood glucose and hemoglobin A1c were (8.6±3.8) mmol/L and (8.2±2.1)%, respectively. There were 52.2% (525/1 006) and 94.4% (958/1 015) of the DFD patients companied with peripheral arterial disease and neuropathy, respectively. DFUs were mainly single (52.7%, 447/849) and neuro-ischemic ulcers (53.0%, 389/734). The main predisposing causes were physical causes (21.6%, 180/834) and trauma (19.2%, 160/834).ConclusionsThe patients with DFD have the characteristics of old age, long course of diabetes, irregular treatment of diabetes and poor control of blood glucose, combined with neurovascular diseases, and high recurrence rate of foot ulcer. Therefore, diabetes education, early screening of foot risk factors, and early intervention should be strengthened to prevent the occurrence and recurrence of DFU.
