Effect and clinical value of splanchnic nerve block of hemodynamics in ACST.

The condition of acute cholangitis of severe type (ACST) develops very rapidly and the prognosis is poor. The main clinical feature is that there is an obvious dynamic variation, which is the principal factor for the early occurrence of shock and death. In this study the Japanese long ear rabbits were used and biliary tract pressure increasing and splanchnic nervous plexus blocking experiments were conducted. Our results indicate that 0.6% of lidocaine can be used to block the right celiac plexus. It can avoid the decrease of blood pressure due to the pressure increase of the biliary tract, and the decrease of blood pressure due to the pressure increase of the biliary tract can be corrected by local anesthesia. 8 cases in conformity with the ACST diagnostic standards received the right renal capsule block injection for the purpose of stopping the celiac plexus, 6 cases of whom had a return of blood pressure to various extent, suggesting that the splanchnic nervous activity in the occurrence of ACST is of great significance. The technique may provide a new approach for the clinical treatment of ACST.
