Abstract: Objective To compare the multiple organ dysfunction score (MODS), the sequential organ failure assessment (SOFA), the acute physiology, age, and chronic health evaluation system Ⅱ(APACHE Ⅱ), the acute physiology, age, and chronic health evaluation system Ⅲ(APACHE Ⅲ) in evaluating risks for patients after cardiac surgery, in order to provide better treatment and prediction of prognosis after cardiac operation. Methods A prospective study was carried out on 1 935 cardiac postoperative patients, including 1 050 males and 885 females, enrolled in cardiac postoperative intensive care unitof Anzhen hospital between October 2007 and April 2008. The age of the patients ranged from 18 to 86 years with the mean age of 53.96 years. The patients underwent the surgery because of various cardiac diseases including coronary heart disease, valve disease, congenital heart disease, aortic aneurysm, pericardial disease, atrial fibrillation, and pulmonary embolism. We used MODS, SOFA, APACHE Ⅱ, and APACHE Ⅲ respectively to calculate the value of the first day after operation, the maximum value during the first three days, the maximum value, and the change of the value between the third day and the first day for every patient, and then we compared the calibration and discrimination of these different systems using HosmerLemeshow goodnessoffit analysis and Receiver Operating Characteristic (ROC) curve. Results There were 47 perioperative deaths because of circulating system failure, respiration failure, kidney failure, liver failure or nervous system diseases. The death rate was 2.43%. In discrimination analysis, the area under the curve (AUC) in ROC of the first day value after operation, the maximum value, the maximum value during the first three days, and the change of value between the third day and the first day for MODS were respectively 0.747, 0.901, 0.892, and 0.786; for SOFA were respectively 0.736, 0.891, 0.880, and 0.798; for APACHE Ⅱ were respectively 0.699, 0.848, 0,827, and 0.562; for APACHE Ⅲ were respectively 0.721, 0.872, 0.869, and 0.587. In calibration analysis, we compared the χ2 value of the first day value, the maximum value, the maximum value during the first 3 days, and the change of value between the third day and the first day of these systems. χ2 value of MODS was 4.712, 5.905, 5.384, and 13.215; χ2 value of SOFA was 8.673, 3.189, 3.111, and 14.225; χ2 value of APACHE Ⅱ was 15.688, 10.132, 8.061, and 42.253; χ2 value of APACHE Ⅲ was 13.608, 11.196, 19.310, and 47.576. AUC value of MODS and SOFA were all larger than those of APACHE Ⅱ and APACHE Ⅲ (Plt;0.05); AUC value of APACHE Ⅱ was smaller than that of APACHE Ⅲ (Plt;0.05). Conclusion MODS, SOFA, APACHE Ⅱ and APACHE Ⅲ are all applicable in evaluating risks for patients after cardiac surgery. However, MODS and SOFA are better than APACHE Ⅱ、APACHE Ⅲ in predicting mortality after cardiac surgery. In cardiac surgery, the complicated APACHE Ⅱ and APACHE Ⅲ systems can be replaced by MODS and SOFA systems which are simpler for use.
To study the effects of early enteral nutrition and selective decontamination of digestive tract on the lipopolysacchride (LPS) translocation and cytokines and the developing of multiple organ dysfunction syndrome (MODS). Thirty six rabbits were divided into 3 groups: ①control group (CON group, n＝12), the rabbits were bled to shock state (MAP was 5.33 kPa) for 1 hour and then were resuscitated by with replacement of the lost blood and 2 volume of the equilibrium liquid, ②selective decontamination of digestive tract (SDD group, n＝12), the procedure was the same as the CON group but the rabbit was fed with the antibiotics 3 days before the experiment and all through the experiment, ③early enteral nutrition group (EN group, n＝12), treatment was the same as CON group. After resuscitation the feeding tube was placed into the stomach for enteral nutrition. On the 1st, 3rd, 5th and 7th day the blood samples were taken for testing the LPS, TNFα and the organs’ function. Results: The MODS incidence, the levels of LPS and TNFα of the EN group were obviously lower than those in SDD and CON groups; the levels of the LPS and TNFα of the SDD group remained high in the 5th day. SDD group had a higher incidence of the MODS and mortality than that of the EN group. Conclusion: Ischemiareperfusion damage can produce the LPS translocation, which causes the development of MODS. SDD can’t decrease the LPS translocation so that the incidence of MODS and mortality remain high. Early EN can inhibit LPS translocation and reduce the development of MODS.
Objective To investigate the hospital outcomes and therapeutic strategy for multiple organ dysfunction syndrome （MODS） in children after cardiac surgery. Methods Seventy-seven consecutive pediatric patients （57 male/20 female, age 3.47±3.67 years, weight 13.08±7.52 kg） with MODS after cardiac surgery were enrolled in the study from 1999.7 to 2005.10. Corrective and palliative operation were performed in sixty-six patients and eleven patients, respectively. We evaluated the clinical score for all study patients according to the extent of organ injury. Results The overall mortality rate was 28. 6%（22/77）. （1） Cardiovascular, renal, hepatic, hematologic, neurologic and respiratory dysfunction was present in 100% （77/77）, 97.4% （75/77）, 84.4% （65/77）, 48.1%（37/77）, 45. 5%（35/77） and 44. 2%（34/77） of the patients, respectively. Cardiac injury appeared much earlier than other organs （P〈0. 05）. （2） Mortality rate with two, three, four, five and six dysfunctional organ systems was 0%, 12.5 %, 31.8 %, 42. 9 % and 87.5 %, respectively （r=0.487, P〈0. 001 in trend）. Furthermore, there was a positive correlation between the clinic score and mortality rate （r=0.603, P〈0. 001）. （3） Compared with survivors, non-survivors had longer cardiopulmonary bypass time, clamping time, higher incidence of accidental events and cardiopulmonary resuscitation during and after surgery （P〈0. 05）. Conclusion Mortality associated with MODS was highly correlated with the number of organ failing and clinical score. Cardiac dysfunction was the primary disease in MODS after cardiac surgery. Therefore, therapeutic strategy for MODS should be focused on management of primary disease, as well as providing consecutive evaluation and improvement for organ function.
ObjectiveTo explore protective strategies for organ function of fulminant acute pancreatitis (FAP) in early stage. MethodsThe clinical data of 37 patients with FAP admitted to this hospital within 72 h after onset of symptoms between January 2000 and September 2010 were analyzed retrospectively. FAP was defined as presence of multiple organ dysfunction syndrome (MODS) within 72 h after onset of symptoms. A total of 37 patients with a confirmed diagnosis of FAP were divided into two groups based on whether adopting the protective strategies for organ function in early stage or not. Patients treated between January 2000 and May 2004 did not adopt the protective strategies for organ function (Named nonprotection group, n=21); The other patients treated between June 2004 and September 2010 adopted protective strategies for organ function (Named protection group, n=16). With the exception of the protecting strategies for organ function, the patients with severe acute pancreatitisin received standard treatment in two groups. The acute physiology and chronic health evaluation (APACHE) Ⅱ score and multiple organ dysfunction score (Marshall), rate of pancreas infection, and case fatality were compared between two groups. ResultsCompared with the nonprotection group on day 3 after admission, APACHEⅡ score and Marshall score decreased in the protection group (APACHEⅡ score : 15.71±2.95 versus 17.72±3.77, P=0.137; Marshall score: 6.93±2.73 versus 8.06±2.36, P=0.206, respectively). In addition, the case fatality on day 7 and in hospital case fatality in the protection group decreased as compared with the nonprotection group (case fatality on day 7: 18.75% versus 33.33%, P=0.461; in hospital case fatality: 43.75% versus 57.14%, P=0.515, respectively). There was no significant difference of the rate of pancreas infection between two groups (P=1.000). ConclusionsIt from a case of a particular disease perspective, though the difference is not significant, but the observed improvement in prognosis is attributed by protective strategies for organ function of FAP in early stage to a certain degree, however it is verified by needing to more cases.
【Abstract】ObjectiveTo explore the changes of colon motility of the rats in multiple organ dysfunction syndrome （MODS） induced bacterial peritonitis and the effects of IL6, TNFα and induce nitricoxide synthase (iNOS) on colon motility. MethodsWistar rats were divided into two groups, which were the control group and the MODS group. The number of stool, the amplitude changes of circular smooth muscle strip, the length of smooth muscle cell, and the changes of serum NO in two groups were observed. The expressions of IL6, TNFα and iNOS protein and IL6 mRNA, TNFα mRNA and iNOS mRNA in distal colon were investigated by using immunohistochemical methods and RTPCR. ResultsThe numbers of stool and the amplitude in the MODS group were lower than those of the control group （P＜0.05）. The expressions of IL6, TNFα and iNOS were negative in the control group, while they were positive in the MODS group. IL6 mRNA,TNFα mRNA and iNOS mRNA were negative expression in the control group, but they were positive expression in the MODS group. The concentration of serum NO and the length of smooth muscle cells in the MODS group were higher than those of the control group (P＜0.01). ConclusionColon motor dysfunction of the rats is related to the iNOS, IL6 and TNFα.
ObjectiveTo summarize the mechanism of hydrogen sulfide (H2S) in regulating autophagy and ameliorating multi-organ dysfunction in the treatment of sepsis.MethodThe relevant literatures at home and abroad in recent years were systematically searched and read to review the mechanism of H2S in regulating autophagy and ameliorating multi-organ dysfunction during sepsis.ResultsAs a new medical gas signal molecule, H2S could regulate autophagy by regulating multiple signal pathways such as Nrf2, NF-κB, MAPK, AMPK, etc., then ameliorated multi-organ dysfunction in sepsis.ConclusionH2S inhibits inflammation, oxidative stress, and apoptosis by regulating autophagy, thus ameliorating multi-organ dysfunction in sepsis, which is expected to become an effective therapeutic target for sepsis.

Objective To investigate the dynamic expression and clinical significance of myoglobin, creatine kinase and inflammatory mediators in the serum of patients with multiple trauma. Methods From May 2013 to March 2015, 56 patients with multiple trauma admitted in EICU were recruited in the study. According to the injury severity, 56 patients were divided into a mild trauma group, a medium trauma group and a severe trauma group. The subjects were further divided into a MODS group and a non-MODS group based on multiple organ dysfunction syndrome (MODS) criteria. Twenty healthy adults undergoing physical examination were recruited as control. Serum myoglobin, creatine kinase, IL-6 and TNF-α levels were measured in the multiple trauma patients (1st day, 3rd day, 7th day and 14th day) and the controls. Results Compared with the controls, the serum levels of myoglobin, creatine kinase, IL-6 and TNF-α in the patients with multiple trauma increased significantly from 1st to 14th day after injury (allP＜0.05). Serum myoglobin, creatine kinase, IL-6 and TNF-α levels on 3rd day after injury reached the peak, then decreased gradually in the mild, medium, and severe trauma groups, among which the changes of serum myoglobin, creatine kinase, IL-6 and TNF-α levels were significant on 3rd day compared with other timepoints (allP＜0.05). On 1st day after injury, serum levels ofmyoglobin, creatine kinase, IL-6 and TNF-α also differed significantly between the MODS group and non-MODS group (allP＜0.05). The AUCs of myoglobin, IL-6 and TNF-α for predicting MODS were 0.527-0.817, 0.641-0.890, and 0.197-0.544, respectively. Conclusions The dynamic changes of serum myoglobin, creatine kinase, IL-6 and TNF-α in patients with multiple trauma are correlated well with the injury severity and prognosis. Serum myoglobin, IL-6 and TNF-α levels may be good markers to predict secondary MODS in multiple trauma patients.
To observe the change in plasma endotoxin and cytokine during the early period of intra-abdominal infection (IAI) complicated by multiple system organ dysfunction (MSOD) in animals. Twenty rabbits were randomly divided in to two groups. One group received the operation of cecal ligation plus puncture (CLP) inducing IAI complicated by MSOD, and another group received sham operation as a control. All animals were placed in metabolic cages and maintained with intravenous infusion for one week. Plasma levels of endotoxin and cytokine (TNF, IL-1, IL-6) were determined seperately at the beginning (0 hour) or 1, 2, 3, 4, 5, 6 and 24 hours after CLP. Blood bacteria cultures and pathological examination of several organs were made when the animal was dead or killed. Results: The levels of plasma endotoxin, TNF and IL-6 were found to be significantly increased at one or two hours after CLP, the incidence rate of bacteriemia was 80% and the pathological alterations in the abdomen and organs were remarkale, with an average survival time of 84.1±39.0 hours in CLP group. No change in plasma IL-1 level was found in the CLP group. Conclusion: The plasma levels of endotoxin and cytokine (TNF and IL-6) do increase in the early period of IAI complicated by MSOD, and the change in plasma IL-1 is not obvious.
ObjectiveTo investigate the role of recombinant human growth hormone (rhGH) in the treatment of patients with multiple organ dysfunction syndrome (MODS). MethodsThirty-eight patients with MODS routinely treated with antibiotics and nutrition support were divided into two groups: the rhGH group and control group. The rhGH group was treated by subcutaneous injection of 5 U rhGH for two weeks. ResultsOn the 7th day of treatment, the score of APACHE Ⅱ in the rhGH group was much higher than the control group, the levels of ALT, AST, BUN and Cre did not change much compared with the control group. The level of albumin in the rhGH group increased (P＜0.05). The stay in ICU, time of mechanical ventilation and hospital stay decreased compared with the control group (P＜0.05). ConclusionrhGH can effectively improve the pathophysiology of critically ill patients and has no side effects on the function of liver and kidney, meanwhile it can shorten hospital stay and decrease mortality.
