A tamponade device for control of refractory liver bleeding is occasionally indicated. This report documents to our knowledge the first reported use of Foley catheter balloon tamponade for severe liver injury.

Comparative Study
Comparison of intraosseous, central, and peripheral routes of crystalloid infusion for resuscitation of hemorrhagic shock in a swine model.
Venous access is often a clinical dilemma in severely hypovolemic children. This study compares fluid resuscitation by central vein, peripheral vein, and the intraosseous route in a hemorrhagic shock model. Hampshire piglets were bled to a mean arterial pressure of 30 mm Hg. ⋯ There was no significant difference in mean arterial pressure, central venous pressure, cardiac output, pulmonary capillary wedge pressure, mixed venous oxygen saturation, or arterial oxygen saturation. Histologically, cellular washout and necrosis were found in bone marrow immediately adjacent to the intraosseous needle infusion site. For fixed-rate infusion, intraosseous crystalloid resuscitation is as efficacious as that delivered by peripheral or central venous routes in reversing hemorrhagic shock.

Survival determinants were examined in patients undergoing ERT-PCI who were admitted to the Surgical Intensive Care Unit (SICU) between January 1, 1982 and August 1, 1991. Twenty-one of 290 patients undergoing ERT-PCI (aged 14-36 years) were admitted to the SICU. Of the 21, nine survived to discharge with normal neurologic function. ⋯ All survivors had vital signs either in the field or on ER arrival. Patients with penetrating chest wounds without vital signs in the field who do not recover vital signs by hospital arrival do not benefit from emergency room thoracotomy. Evidence of mentation in the field or on arrival may predict ultimate neurologic outcome of survivors.

Isolated dorsal dislocation and rotatory dislocation of the second carpometacarpal joint is rare. A case of rotatory dislocation of this joint is presented, where reduction was blocked by entrapment of the extensor carpi radialis longus tendon in the joint. A roentgenographic technique for evaluating dislocation of carpometacarpal joints is also described.

The baseball bat, according to Baltimore City police crime statistics, is a commonly used weapon. To assess the severity of injuries inflicted by this modern-day club, we retrospectively reviewed 75 charts of patients treated at the University of Maryland Medical Systems Hospital for baseball bat injuries from January 1990 through July 1991. ⋯ In our series, the history of loss of consciousness and the Glasgow Coma Scale score failed to reliably identify the patients with serious injuries. Seventeen percent of our patients with intracranial hemorrhages had both a negative or uncertain history of loss of consciousness and a normal Glasgow Coma Scale score on arrival.
