  • Research of Continuous Regional Arterial Infusion of Dexamethasone Treatment for Severe Acute Pancreatitis

    ObjectiveTo study the effects of continuous regional arterial infusion (CRAI) of dexamethasone on plasma inflammatory factors of severe acute pancreatitis (SAP) rabbits. MethodsTwentyfour rabbits were randomly divided into sham operation group, SAP group, intravenous infusion of dexamethasone group and CRAI of dexamethasone group (each group 6 rabbits) by random number table. The serum tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10, and amylase (AMY) levels in rabbits were tested at hour 0.5, 3, 6, 9, and 12 after modeling succeed. The pathological changes of pancreas and the survival were observed on day 3 after modeling succeed. ResultsCompared with the sham operation group, the serum levels of IL-6 significantly increased at 3 h and reached the peak at 6 h, decreased at 9 h (all Plt;0.05); levels of IL-10 significantly increased at 6 h, continuously elevated at 9 h and 12 h (all Plt;0.001); levels of TNF-α significantly increased at 0.5 h (Plt;0.001), reached the peak at 6 h (Plt;0.001) and decreased at 9 h (Plt;0.05); levels of AMY significantly increased at 9 h, continuously elevated at 12 h (all Plt;0.05) in the SAP group. Compared with the SAP group, the serum levels of IL-6 and IL-10 in the CRAI of dexamethasone group all significantly decreased at 6 h, 9 h, and 12 h (Plt;0.001); levels of IL6 significantly decreased only at 6 h in the intravenous infusion of dexamethasone group; levels of TNF-α in the CRAI of dexamethasone group significantly decreased at 3 h, 6 h, 9 h, and 12 h (all Plt;0.001), which in the intravenous infusion of dexamethasone group significantly decreased only at 6 h (Plt;0.05); levels of AMY in the CRAI of dexamethasone group and intravenous infusion of dexamethasone group all significantly decreased at 12 h (Plt;0.05). Compared with the intravenous infusion of dexamethasone group, the serum levels of IL-6 and IL-10 in the CRAI of dexamethasone group all significantly decreased at 6 h (Plt;0.05) and 12 h (Plt;0.001); levels of TNF-α all significantly decreased at 3 h, 6 h, 9 h, and 12 h (all Plt;0.001); levels of AMY were not significantly different (Pgt;0.05). The pathological changes of pancreas in the CRAI of dexamethasone group were obvious, the death of rabbits reduced on day 3 after modeling succeed. ConclusionCRAI dexamethasone can effectively reduce the systemic inflammatory response and pancreatic inflammation, and reduce mortality.

  • CONTINUOUS REGIONAL ARTERIAL INFUSION IN THE TREATMENT OF SEVERE ACUTE PANCREATITIS AND PREVENTING LIVER DAMAGES IN RATS

    【Abstract】Objective To investigate a more rational modality which is in the treatment of severe acute pancreatitis (SAP) and effective in preventing liver from damages due to SAP. Methods SAP model was established by retrograde injection of 5% sodium taurocholate (1.0 ml) in the subserosa of pancreas in rats (n=80) weighting 200-250 g.The rats were catheterized using PE-50 angiocatheter from femoral artery to celiac trunk. Then they were randomly divided into four groups. Twenty animals served as controls (A group) and received only fluid infusion. The 40 animals, B and C group (20 animals in each one group) received continuous regional arterial infusion (CRAI) of somatostatin (4 μɡ/kg) and the medicines improving microcirculatory (dextran-40 1.5 ml, dopamine hydrochloride 5 μg/kg, anisodaminum 1.5 ml/kg) respectively. The other 20 animals (D group) were treated by somatostatin combined with the medicine improving microcirculatory through CRAI simultaneously with the induction of pancreatitis. The AST, ALT, ALP and serum amylase were recorded, the liver and pancreas tissue were observed pathologicaly after 6 hours. Results There were a ignificant decrease in the serum amylase in B group (Plt;0.05) and D group (Plt;0.05). The AST, ALT, ALP was decreased in B and D group (Plt;0.05). The damage to liver and pancreas were reduced in D group. Conclusion CRAI is effective in preventing liver damages due to SAP and is an effective way in the treatment of SAP.
