Ketamine Use for Successful Resolution of Post-ERCP Acute Pancreatitis Abdominal Pain

We report a case in which a patient with intractable pain secondary to post-endoscopic retrograde cholangiopancreatography (ERCP) acute pancreatitis is successfully treated with a subanesthetic ketamine infusion. Shortly after ERCP, the patient reported severe stabbing epigastric pain. She exhibited voluntary guarding and tenderness without distension. Amylase and lipase levels were elevated. Pain persisted for hours despite hydromorphone PCA, hydromorphone boluses, fentanyl boluses, and postprocedure anxiolytics. Pain management was consulted and a ketamine infusion was trialed, leading to a dramatic reduction in pain. This case suggests that ketamine may be a promising option in treating intractable pain associated with ERCP acute pancreatitis

Survey of techniques to reduce/minimize the control part/ROM of a microprogrammed digital computer

A survey was made of most of the important research to date on minimizing the control part of a microprogrammed digital computer. The results appear to be negative, i.e., the Glushkov and Schwartz approaches do not seem feasible in any practical environment. If the requirements of minimal solution are removed so that one would be satisfied with a near minimal solution, the integer programming method can be used since a very good solution is usually obtained after the ftrst iteration.

Comments on capabilities, limitations, and correctness of Petri nets. Report 26

Petri nets were one of the earliest contributions to the theory of parallel computations and appear to be a natural way to represent the coordination of asynchronous events. Petri nets, however, are not restricted to modelling coordinates in computer systems. Any system where there are loosely connected essentially independent processes that proceed in an asynchronous marner can be modelled using Petri nets and should be useful in modelling business systems and biological systems.
