Apnea (APN) and pneumothorax (PTX) are common immediately life-threatening conditions. Ultrasound is a portable tool that captures anatomy and physiology as digital information allowing it to be readily transferred by electronic means. Both APN and PTX are simply ruled out by visualizing respiratory motion at the visceral-parietal pleural interface known as lung sliding (LS), corroborated by either the M-mode or color-power Doppler depiction of LS. We thus assessed how economically and practically this information could be obtained remotely over a cellular network. ⋯ The emergent exclusion of APN-PTX can be immediately accomplished by a remote expert economically linked to almost any responder over cellular networks. Further work should explore the range of other physiologic functions and anatomy that could be so remotely assessed.

The treatment of interprosthetic femoral fractures is challenging because of several factors. Poor bone stock, advanced age, potential prosthetic instability, and limited fracture fixation options both proximally and distally can complicate standard femur fracture treatment procedures. The purpose of this report was to describe our experience treating interprosthetic femoral fractures, providing an emphasis on treatment principles and specific intraoperative management. ⋯ The principles for treatment of isolated periprosthetic fractures are useful to guide the fixation of interprosthetic fractures. Locked plating is an effective method for the treatment of interprosthetic femoral fractures. Bypassing the adjacent prosthesis by a minimum of two femoral diameters is a necessary technique to prevent a stress riser.

To investigate the factors that influence final visual acuity (VA) in open globe injuries. ⋯ In this retrospective study, the most important factors influencing final VA were initial VA, retinal detachment, and vitreous prolapse, all of which are important with regard to informing the patient of the prognosis and determining the approach the physician will take.

Comparative Study
Low complication rate associated with raising mature flap for tibial nonunion reconstruction.
Tibia fractures may require soft tissue coverage with transposed tissue and can develop nonunions. Tibial defects can be approached with a posterolateral approach or by elevating the previously transposed tissue. No literature has previously reported the efficacy or safety of the latter approach. The purpose of this study was to report the flap survival rate and complications from delayed elevation of transposed soft tissue as part of a protocol for the treatment of tibia nonunions. ⋯ This is the first report of the survival and complication rates for delayed elevation of soft tissue flaps for tibial nonunion reconstruction. A total of 95.8% of flaps survived elevation. Flap elevation seems to be an alternative to posterolateral tibial approaches for treatment of tibial nonunions.

Comparative Study
Hextend and 7.5% hypertonic saline with Dextran are equivalent to Lactated Ringer's in a swine model of initial resuscitation of uncontrolled hemorrhagic shock.
The optimal fluid strategy for the early treatment of trauma patients remains highly debated. Our objective was to determine the efficacy of an initial bolus of resuscitative fluids used in military and civilian settings on the physiologic response to uncontrolled hemorrhagic shock in a prospective, randomized, blinded animal study. ⋯ Withholding resuscitative fluid results in the least amount of posttreatment blood loss. In clinically used volumes, HEX and HTS are equivalent to LR with regard to physiologic outcomes and superior to NF. NS did not provide a measurable improvement in outcome compared with NF and resulted in increased acidosis.
