To examine whether well-trained paramedics can perform emergent, successful, uncomplicated, endotracheal intubations during in-hospital cardiopulmonary resuscitation (CPR). ⋯ Paramedics can successfully, and without undue difficulty or complications, place endotracheal tubes during in-hospital CPR. Appropriately trained paramedics may be incorporated into hospital-based CPR teams in two contexts: (1) to provide an acceptable, long-term solution to the scarcity of personnel highly skilled in endotracheal tube placement during in-hospital CPR, and (2) to fulfill the need for hospitals to have on-site, qualified professionals to perform emergent endotracheal intubation during CPR. In the latter situation, personnel skilled in airway management could supplement the paramedics on demand. Further investigation in this area could be fruitful in view of the small sample size covered in this study.

The present study was designed to test whether there was a significant improvement in pulmonary function and arterial blood oxygenation after therapeutic thoracentesis on patients with inversion of a hemidiaphragm due to pleural effusion. In 21 patients with inversion of a hemidiaphragm because of a pleural effusion, we studied the changes in pulmonary mechanics and gas exchange that occurred in 24 h after removal of 600 to 2,700 mL of fluid by thoracentesis. ⋯ The alveolar-arterial oxygen gradient (P[A-a]O2) and partial pressure of arterial oxygen (PaO2) showed a significant increase (p < 0.001), but there was no change in partial pressure of arterial carbon dioxide (PaCO2). In the present study, all patients with a large pleural effusion had inversion of a hemidiaphragm documented by chest sonography, and that was an important factor to observe significant improvement in pulmonary mechanics and gas exchange.
