| Intraosseous infusion (10) was developed in the 1920s and 1930s, and has been an important vascular access in prehospital setting or pediatric emergency department. In these cases, fluid infusion was a useful and important method of resuscitation from haemorrhagic shock by traumatical injury. 10 was a simple and efficient alternate route for fluid and certain drug administration during these emergencies, especially where the other techniques which provide vascular access became impossible or inadequate by the circumstances limitation, vein collapse, and so on. Much literature indicated that the 10 flow rate was receivable especially under a high-pressure condition, but it is still limited compared with the flow rates of other vascular access methods. Hyperosmotic fluid resuscitation has been developed for many years, and it possessed a prominent characteristic of requiring a small volume of fluid. So, the combination of 10 and hyperosmotic fluid supplied a new method for haemorrhagic shock.. in this study, to further research the f of hvperosmotic fluid. how rate, resuscitation effects and complications of 10 were evaluated. The results showed that the 10 flow rate under gravity was enough for hyperosmotic fluid resuscitaion: the resuscitative effect of 10 of hyperosmotic fluid was as the same as the other vascular access methods by the analysis of blood pressure. the heart rhythm, biochemical indexes, artery blood gas analysis and so ON; and [0 of hyperosmotic fluid did not induce osteomvelitis. 10 of hyperosmotic fluid was safe.TOt8lly, thcse resuIts suggested that IO of hyperosmotic nuid wasas same safe and reliable as peripheral intraverous administration forhaemorrhagic shock, and couId be wideIy uscd. |
