The purpose of this paper is to present a series of observations on the intraperitoneal pressure that was recorded during the course of pneumoperitoneum treatment of 91 patients with pulmonary tuberculosis. For measuring the intraperitoneal pressure the manometer of an ordinary pneumothorax apparatus, graduated in half centimeters, was used. The patient was in the supine position except when the needle was introduced by the subdiaphragmatic route, in which case he was lying on his side. In the overwhelming majority of instances the site of insertion of the needle was 3 fingerbreadths below and to the left of the umbilicus. When the subdiaphragmatic route was used the needle was inserted slightly above the costal margin. All manometer readings were taken during quiet respiration.
The initial treatment was always given by the subumbilical route. The intraperitoneal pressure at this point is, as a rule, neutral (atmospheric). There were only 7 patients for
