In the course of a survey of a large clinical material, we have found a surprising amount of laboratory data collected in the management of 1,904 patients with acutely perforated gastroduodenal ulcers. We have previously reported on general factors influencing the incidence and mortality of these patients admitted to the Cook County Hospital between 1936 and 19551 and on the clinical signs and symptoms which had some prognostic value in the outcome of this same series of patients.2 This report is concerned with the laboratory data available in this series of patients.
As previously described,1,2 the survey method consisted of the screening by 2 registered nurses trained as medical record historians of over 16,000 records of
