Clinical and demographic characteristics of 122 patients undergoing cardiopulmonary resuscitation were retrospectively collected to develop a predictive model for immediate success of resuscitation (restoration of pulse and blood pressure). The project focused on objective measurement of parameters available before resuscitation was performed. ⋯ The four predictive before arrest factors were age between 40 and 70 years, scheduled for surgery, location of arrest in an intensive care unit, and before arrest PO2 greater than 8 mm Hg. The model had an accuracy of 69%, sensitivity of 76%, and specificity of 61%.

The hyperviscosity syndrome is most commonly seen in association with monoclonal gammopathies and has only rarely been described in association with polyclonal hypergammaglobulinemia. We have recently seen a patient with known acquired immunodeficiency syndrome who presented with the hyperviscosity syndrome in the setting of polyclonal hypergammaglobulinemia. To our knowledge, this is the first reported case of a patient with the acquired immunodeficiency syndrome and the hyperviscosity syndrome. The case is presented and the pathogenesis and implications of this diagnosis are discussed.
