  2. COMBAT FLUID RESUCITATION • On today’s battlefield medical providers will be required to manage their patients fluid resuscitation from point of wounding until their arrival at the FST or CSH. • CASEVAC/MEDEVAC assets may be delayed or mission may require patient hold on the battlefield or in the BAS for hours to days. • Hypotensive resuscitation initially • Maintenance protocols • I&O monitoring

  3. HYPOTENSIVE RESUSCITATION • IV access must be gained. The use of a single 18 gauge catheter is recommended. • A heparin, saline lock-type access tubing, extension set, or 3 way stop-cock should be used unless the patient needs immediate resuscitation. • Insure the IV site isn’t established distal to a significant wound.

  4. HYPOTENSIVE RESUSCITATION • Splint if the site is over a joint to prevent dislodgement during transport. • If unable to start an IV consider starting a sternal Inter-Osseous line to provide fluids. A caveat-If you do this insure the skin is prepped well. Osteomyelitis in the manubrium is VERY BAD!!!

  5. FLUID RESUSCITATION • After initial resuscitation if CASEVAC/MEDEVAC is impossible or delayed for any reason; fluid maintenance must be recalculated based on the patients condition, supplies, and time available. • Maintenance rate calculation when NPO: (Weight in Kg) + 40 = ml per hour of infusion rate.

  6. FLUID RESUSCITATION • End Points of resuscitation for controlled hemorrhage and dehydration: • Normal BP • Pulse • Urine output (0.5-1 ml/kg/hr) • Normal capillary refill • Good mentation

  7. FLUID RESUSCITATION • If patient can accept p.o fluids begin Oral Rehydration Salts (ORS) , water, and “other fluids” as tolerated. • Pre-packaged ORS are very prevalent “Downrange”, but patients for the most part, hate the taste and will require some encouragement. Gatorade though not quite as good has better compliance. • ORS Recipe- 4 tsp sugar, ½-1 tsp salt, 1L water

  8. BURN RESUSCITATION • Adults: 2-4 cc LR x Kg body weight x % BSA burn. • Children: 3-4 cc LR x kg body weight x % BSA burn.

  9. BURN RESUSCITATION • The infusion rate is regulated so that ½ the estimated volume will be administered in the first 8 hours post burn-the time when capillary permeability and intra-vascular volume loss are greatest. • The remaining half of the estimated resuscitation volume should be administered over the subsequent 16 hours of the the first post burn day.

  10. BURN RESUSCITATION • The burn victim requires fluid maintenance in addition to the initial resuscitation!

  11. IV DRIP RATE CALCULATION • Macro Drip: Delivers rates greater than 100 ml/hr (Drip factor is 10 to 15 gtt/ml depending on equipment used. Drop Factor is printed on the box. • Micro Drip: Delivers rates less than 100 ml/hr. Most commonly 60 gtt/ml.

  12. CALCULATING FLOW RATE Flow Rate (ml/hr) = Total Infusion (Vol in ml) Hours of Infusion Time gtt factor x Flow Rate = Drop Rate 60 1 Example: Infuse 120ml/hr via 10gtt/ml Drop Factor

  13. ALTERNATE METHOD FOR CALCULATION • If drop factor is 10 gtt/ml, take ordered rate per hour and divide by 6. • If drop factor is 15 gtt/ml, take ordered rate per hour and divide by 4. • If drop factor is 20 gtt/ml, take ordered rate per hour and divide by 3. • If drop factor is 60 gtt/ml, take ordered rate per hour and divider by 1.

  14. MONITORING I & O • Appropriate for patients that for whatever reason are in a hold status, and their condition requires close monitoring to maintain hemostasis. • Anticipate, and bring graduated containers. • Normally calculated q 8 hrs. • Compare 24 hr totals over several days. • Utilize resuscitation endpoints and UOP to help in making a CLINICAL DECISION • Increase or decrease the fluid maintenance based on your CLINICL DECISION
