Twenty-three cases of inferior vena caval injury (1.4% of all operatively managed abdominal injuries) are reviewed. The caval injury presented as free haemorrhage in 15 cases and as a retroperitoneal haematoma in eight. The site of vena caval injury was at or above the level of the renal veins in 14 cases (61%). ⋯ Factors positively associated with survival were stab wound, presentation as retroperitoneal haematoma, infrarenal injury, low Abdominal Trauma Index score and small peroperative blood loss. Concomitant injury to the abdominal aorta, liver or kidney worsened the prognosis. The crucial factor in management of inferior vena caval injuries is rapid and effective control of bleeding, whether from the caval or associated injuries.

Comparative StudyHigh frequency jet ventilation in tracheobronchoplasty. An experimental study.
An experimental study on dogs was performed to determine the optimal driving gas pressure and frequency in high-frequency jet ventilation (HFJV) during tracheobronchoplasty. Right thoracotomy, sleeve upper lobectomy and sleeve pneumonectomy were done with various HFJV settings and insufflation via a 3.0 mm catheter with 2.4 mm internal diameter. ⋯ Driving gas pressure 0.5-1.0 kg/cm2 and frequency 6-10 Hz were the optimal settings for sleeve lobectomy. In sleeve pneumonectomy adequate ventilation and oxygenation were achieved with HFJV to the contralateral lung, and the optimal HFJV settings were 1.0-2.0 kg/cm2 driving gas pressure and 6-10 Hz frequency.
