Objective To investigate the relationship between early fluid management and the conversion rate to surgery in patients with sever acute pancreatitis( SAP) .Methods The patients with SAP admitted in ICU in West China Hospital from July 2005 to June 2010 were retrospectively analyzed. They were divided into four groups according to the quartile of the accumulated fluid balance in the first three days after admission in ICU( lt; 25% , 25% ～50% , 50% ～75% , and gt; 75% , respectively) . The major demographic data, clinical characteristics, mortality, and conversion rate to surgery were evaluated respectively. Results 208 patients were enrolled. For each quartile, the conversion rate to surgery decreased at first, and then increased along with the increase of the accumulated fluid balance. Significant difference existed between the second quartile with the lowest conversion rate to surgery and other three quartiles ( P lt; 0. 05) . Differences were also found in mortality and the score of acute physiology and chronic health evaluation Ⅱ( APACHEⅡ) on 24th and 48th hour between the first three quartiles and the last quartile with the highest mortality and APACHⅡ score( P lt;0. 05) . However, sex ratio, age, Ranson criteria, and the score of sequential organ failure assessment( SOFA) did not have significant differences among each quartile( P gt; 0. 05) . Conclusion Fluid management in early stage can influence conversion rate to surgery and mortality in patients with SAP.
Objective To investigate the efficiency of combining traditional Chinese medicine with western medicine in the treatment of severe acute pancreatitis (SAP). Methods The clinical results of sixty three cases of SAP of non-operative treatment with injection of Salia miltorrhizae composita, and oral or gastric tube feeding of decoction Qing-Yi-Tang were retrospectively studied. Results Thirty four cases were categorised as SAP Ⅰ grade, and 29 cases as SAP Ⅱ grade. A variety of complications occurred in 19 cases (30.16%), 3 patients died (4.76%), and 4 patients developing abscess of pancreas (6.35%) which had to be operated on.Conclusion The individualization principle on the basis of cause and clinical stage of the disease should be stressed in treating SAP. The patients who had complication needing to be operated on should be timely performed. There is a good efficiency in the treatment of SAP with the traditional Chinese medicine combining with western medicine.
Objective To study the effects of edaravone on the lung injury of severe acute pancreatitis （SAP） in rats. Methods Thirty-six SD rats were randomly divided into three groups: normal control group, model group and edaravone group, and SAP was induced by intraductal administration of 5% sodium taurocholate. Edaravone was given in edaravone group, while normal saline was given in normal control group and model group. After operation 6 h rats were executed, and dry/wet weight (D/W) ratio of lung was counted, and malondialdehyde (MDA) content, superoxide dismutase (SOD) activity in serum and lung were detected, respectively. In addition, the levels of tumor necrosis factor-α (TNF-α), interleukin-1, -6 (IL-1, -6) of serum were detected.Results The MDA contentof serum and lung and the levels of TNF-α, IL-1, IL-6 in model group were markedly higher than those in normal control group and edaravone group, but D/W ratio of lung, SOD activity of serum and lung were significantly lower (Plt;0.05). Conclusion Edaravone can alleviate lung injury of rats caused by SAP.
ObjectiveTo observe the effect of different preoxygenation methods for emergency intubation in severe patients in intensive care unit (ICU). MethodsProspective randomized study was performed in the intensive care unit between June 2013 and January 2014. Forty patients were randomly divided into 4 groups:group A (control group, n=10), group B (bag-valve-mask preoxygenation group, n=10), group C (noninvasive ventilator-mask preoxygenation group, n=10), and group D (invasive ventilator-mask preoxygenation group, n=10). Standardized rapid sequence intubation was performed without preoxygenation in group A; preoxygenation was performed by using a bag-valve-mask rose pulse oxygen saturation (SpO2) to 90% before a rapid sequence intubation in group B; preoxygenation was performed by using noninvasive ventilator through a face mask rose SpO2 to 90% before a rapid sequence intubation in group C; and preoxygenation was performed by using invasive ventilator through a face mask rose SpO2 to 90% before a rapid sequence intubation in group D. We recorded the time when SpO2 was more than or equal to 90% in group B, C, and D, and arterial blood gases and complications were observed. ResultsThere was no significant difference in the basic indexes before preoxygenation among the four groups (P>0.05). The time of the patients in group D and C was significantly lower than that of group B. The arterial oxygen saturation (SaO2) and arterial oxygen partial pressure (PaO2) in the group C and D were higher than those in group B after preoxygenation (P<0.05). After intubation, SpO2 in group B, C and D was significantly higher than that in group A (P<0.05). At the same time, SpO2 in group C and D was higher than that in group B (P<0.05); PaO2 and SaO2 in group C and D were higher than in those in group A and B (P<0.05); SaO2 in group D was higher than that in group B (P<0.05). The incidence of abdominal distension in group D was significantly lower than that of group B and C (P<0.05). ConclusionFor emergency tracheal intubation in critically ill patients in the ICU, preoxygenation is more effective than the rapid sequence intubation without preoxygenation in improving oxygenation indicators. Invasive ventilator-mask preoxygenation efficacy and safety are superior to other methods.
Objective To summarize experiences of surgical treatment and long-term results of myasthenia gravis (MG). Methods Two hundred thirty-six patients underwent thymectomy for MG in our department from Jan.1978 to Dec. 2002. The perioperative management, relative factors of postoperative crisis and long-term results were analysed. Results In 236 patients postoperative crisis took place in 44 cases accounted for 18.6%. The occurrence of postoperative crisis was related to preoperative management, modified Osserman clinical classification and combination with thymoma. Three cases died in the postoperative periods. Among them, one died of acute respiratory distress syndrome induced by aspiration and the other died of crisis. The effective rate in 1, 3, 5 years was 84.6%, 91.0% and 89.0% respectively. Conclusions Thymectomy for MG is safe and effective. Delayed extubation could decrease the needs of tracheotomy in patients with high risk factors for postoperative crisis. The partial sternotomy approach is less traumatic but the long-term effects of surgery are identical to those reported by the most authors.
ObjectiveTo summarize the changes and interaction of the cytokine in severe acute pancreatitis associated lung injury. MethodsThe published literatures at domestic and aboard in recent years about severe acute pancreatitis associated lung injury were collected and reviewed. ResultsThe cytokines had a chain effect, and influenced each other when severe acute pancreatitis with lung injury attacked. ConclusionsRelated cytokines play important roles in severe acute pancreatitis associated lung injury. Researching the related cytokines will contribute to the diagnosis and treatment for severe acute pancreatitis with lung injury.
