[Qualitative and quantitative puncture examination of lateral canals of the abdominal cavity in closed abdominal injury].

The diagnostic puncture of lateral canals of the abdominal cavity in patients with closed trauma of the abdomen was made in 312 patients with associated trauma. Negative results were obtained in 166 patients. Retroperitoneal hematomas were diagnosed in 66 patients, reliable in 98.5%. In 80 patients injuries of the abdominal organs were diagnosed. The volume of intraabdominal blood loss (accurate within 80.7%) was determined before operation in 31 of them with the help of puncture with +/- 200 ml error. The diagnostic significance of lateral canals was 99.7%. Complications were the involvement of the liver in 4 patients not requiring any curative measures.
