Purpose A basic review and discussion of the interrelated lessons learned in military medicine - as they relate to changes in the combat and operational environments. TCCC principles and a review of the current tactical pain control guidelines. 1 11/11/2013 Goal At the end of this block of instruction you should have a better understanding of the subtle differences in managing patients in wartime operations, peacekeeping missions, state and local disaster operations. Introduce new concepts in tactical battlefield care and our approach to pain control. The Past…The Future… Ancient Middle Ages Colonial Civil War Transitional Modern Technological future History Gates of Baghdad Ancient Minaret Propaganda an ancient tool Royal Palace 2 11/11/2013 A Shamal…or Haboob…Sand Storms were written about by Alexander…Operation Environment Gates of Babylon Udais’ Palace on the Euphrates River Historical Perspectives… Middle Ages…the Byzantine Empire around the Fourth Century A.D. preserved the Roman System. Islamic Empire increased the medical knowledge base by assimilating the useful practices of conquered territories. Feudal Europe around A.D. 800, Charles the Great (Charlemagne) created a loose confederation that used a standing Army and military medics in units. It would last until the fifteenth century! 3 11/11/2013 Castle DuleGrad near Austro-Hungarian border …we flew over this area during the Balkans war…this castle was used as a Hospital when it was taken by the Moors in the 1400 Century. Entrance to DuleGrad Castle during SFOR-9 Historical Perspectives… The Moors created mobile hospitals…later copied by the Spanish in 1453. Then came “gunpowder” and the nature of War changed dramatically…it also changed what the physicians saw! The Aristocracy were always Officers and nearly always had access to a physician. The enlisted commoner had access to a barber-surgeon who was trained OJT…so to speak… 4 11/11/2013 The Eighteenth Century Jean Louis Petit 1718, invented the screw tourniquet. Pierre-Joseph Desault 1740, pioneered necrotic debridement. John Pringle 1740, introduced the idea of infectious disease to military doctrine. U.S. Military Medical Experience Dr. Joseph Warren, Breeds Hill, 1775 Hospital Salaries: Director General $4.00/day, Surgeons $1.66/day, Apothecary $1.66/day, Nurses $2.00/month Field Hospitals established by Dr. Johnathan Potts Dominique Jean Larrey and evacuation under Napoleon Florence Nightingale Crimean War Jonathan Letterman and the Army of the Potomac Dr. Lyster WWI, WWII, Korea, Viet 1900 Century and Field Sanitation Rat Catcher Soldiers thrown… Vector control 5 11/11/2013 Disease Non-Battle Injuries Historically killed nine soldiers to every one soldier who would die from wounds. Enemy is poor hygiene, disease, and accidental injury. For every one sick and injured soldier, it takes three soldiers to render care. Good sanitation and field hygiene are utmost in maintaining an Army…General George Washington, 1779, address to Congress requesting funding of hospital tents, soap, and listers… Washington made Smallpox vaccinations “Mandatory for all Continentals”…and you thought the mandatory Anthrax series was controversial! DNBI’s Cholera anthrax The very young and the very Old…Potocari Massacre 1998 Plague Katrina Cajun saving his weed wacker Meanwhile not 25 feet away… Hurricane Katrina…24 hours after! 6 11/11/2013 Ted Kopple TC-3 Medicine Paradigm shift in philosophy Different approach but similar basic principles Doc’s are part of the team. Managing pain far forward. Tactical Medicine is a different way of practicing medicine in a disaster. Suppressing enemy fire has priority. Treatment may be a secondary option. Pain management early. Tactical considerations. Tactical Management - Fallujah 2004 Assess MOI and lethality Medics must learn scene Assessment! Avoid traps NTOI 7 11/11/2013 Scene Security…Basrah 2005 My Helmet after getting my Bell rung Modern Medical Principles Triage “Old” Golden Hour DIME Method Marking Evacuation Categories Modes Tracking Arrival at definitive care Early Pain management Early use of Ketamine.

Sam Houston The real deal! 10 11/11/2013 Operational Conditions Kosovo Often Remote Lacking amenities Must at least be secure for the MFST DART teams function almost always in hostile environments and under indirect or direct fire Kosovo Evacuation Assets? OEF Ground OIF SFOR9 Air Wheeled Extraction Requires the medic or Doc’ to understand the specifics of scene command and control. Established TC-3 Understand ground slopes, directional headings, blade clearance, lift capacities, over flight abilities, established primary and secondary ground evacuation routes, marking parties, clearing parties, patient movement, MRO, and your MORE…it can get complicated. SINGARS Commo, versus open text, or SARDOT. SIGINT is always evolving. 11 11/11/2013 Asymmetric Warfare Tactical Combat Care MROE Doc’s will suppress enemy fire actively in a firefight. Treatment on rare occasion will be your second duty. Once a secure perimeter is established then triage, treatment, and evacuation can occur. Pain management from the point of injury. Tactical mind set is VERY important LMA’s Combitubes instead of white light intubation Rapid use of tourniquets…IO/IV…Rapid Pain relief with Ketamine and Morphine - etc. Anecdotal Evidence in reduction of PTSD with rapid pain control. TBI and Hemmorrhage 12 11/11/2013 Blast Injuries - Pain See diagram below! Follow on attacks Pain and Wound Signatures Stationary or moving VBED and IED Generally set to block and MSR Remotely detonated and spray the area with nails, metal shards, glass, marbles, pellets. Tactical Assessment Suppress and return fire. Control bleeding Control pain (IO/IV) Drug selection considerations Less focus on C-spine control Airway Breathing Circulation Disability Exposure Follow-up 13 11/11/2013 Technology and Wounds NVG’s Flack Vest’s Shoulder, Elbow, and Knee pads One handed tourniquets HEMCON, QuikClot Tactical Training and early self management of pain. Reduced IR heat signatures for uniforms, equipment, aircraft. Early pain control reduces PTSD. Can they still fight is the key question. Doc’s now fight back ~ consideration on their role as a non-combatant. Advances in Airway Intubations, combitubes, LMA. Needle Crich’s. (time/exposure) Chest Decompression. (time/exposure) Mechanical Ventilation Assist Devices. (noise/power) Portable Suction Devices. (noise) Compressed Oxygen versus concentrators. (noise/exposure) Thought about that one while loading patients in Fallujah? 14 11/11/2013 Airway Selection The Combitube™ is a double-lumen tube with an esophageal obturator airway and a standard cuffed ET tube. It is inserted blindly and "seals" the oral and nasal pharyngeal cavities. Ventilation in normal and abnormal airways Airway management in trapped patients Patients with intact gag reflexes Patients with known esophageal pathology Use in patients under 5 feet with standard Combitube™, under 4 feet with Combitube™ SA (small adult) Requires minimal training May be more useful in non-fasted patients Successful passage and ventilation in many patients via esophageal route Portable, useful in remote setting Functions in either the trachea or esophagus Airway - Chest Traditional Chest tubes Ashermans one way valves Watergel’s…the Watergel actually worked well as a secondary sealer on an SCW. This has been mitigated well secondary to developments in flack vest technology. Hemostasis HEMOSTASIS is critical. Most common cause of death in Iraq and Afghanistan – bleed out. Impregnated bandage technology. Quick Clot. HEMCON Dressings. One Handed Tourniquets. IVF’s with Heta Starch versus LR. Depends on who you are and where you are…in my opinion. 15 11/11/2013 Hemostasis - HemCon ® HemCon bandages have demonstrated superior hemorrhage control on the battlefield without reported adverse reactions and numerous lives have been saved due to this medical advancement. Here's how they work: Red blood cells and bacteria have a negative surface charge. A chitosan bandage carries a positive charge. When the HemCon dressing is pressed on a severely bleeding wound, it binds electrostatically in one to five minutes. The bandage also forms a muco-adhesive glue that seals to the tissue, but the bandage can be easily removed with water. *Chitosan is derived from shrimp shells. "This is a tremendous validation of our technology by an important partner and customer, the U.S. military," said HemCon Chief Executive John Morgan Shrimp allergic soldiers remain the only minimal issue…they number less then 1% of soldiers in the filed. Hemostasis As was the case with the original QuikClot® hemostat, the new product was co-developed with the United State Navy and Marines and was tested by the Uniformed Services University of Health Sciences (USUHS) and the Naval Medical Research Center (NMRC). Quick Clot ® hemostat, an inorganic molecular sieve. Both products have 510(k) clearance from the FDA. Hemostasis 16 11/11/2013 Hemostasis - Tourniquets The SPECOP’s one on top has a single hand applications with a rotating windlase which works the best. Tourni-Kwik is not as effective…in my opinion… Dressing Technology How It Works When removed from their vacuum pouches the bandage expands and returns to its original shape. When unrolled the coverage area will be a thick 8"x10" absorbent pad. All bandages have a coated steel tension hook sewn on the side away from the absorbent pad, and Velcro strips at both ends of the bandage for easy anchoring and attachment. Self Cinching dressings Primed Gauze with Chitosan Shock and Pain Considerations Crystalloid: LR, NSS… Colloid: Albumin, Heta Starch, Dextran, and Gelatin Hypertonic: 3, 5, 7.5% +/- Dextran Designer Crystalloids: Ethyl Pyruvate Ringers Hemoglobin Based Oxygen Carriers Some indications that Ketamine will maintain BP and doesn’t effect Respiratory drive like Morphine. Down side is there is evidence the Ketamine can increase myocardial oxygen consumption. Population is at low risk for predisposing heart disease. 17 11/11/2013 Shock and Pain We had young healthy soldiers and even though there are issues with HETA Starch. It was our tactical fluid of choice. You have better bioavailability for volume expansion. Two 500 cc bags of HETA had the same effect for expansion as did four liters of LR. If you were non-tactical then our Protocol was HTS and Dextran for hypovolemic shock management. Good plasma expansion, reduced ICP’s, reduced vasospasm, reduced immunomodulation and fewer neurochemical effects. (Doyle et al, J Trauma 2001) Blood Replacements Poly-Heme (Northfield Labs): *Pre-Hospital trial sponsored by the DOD is in phase II. Hemopure (Biopure): *DOD Trial was on going and was being used for trauma victims. It is in phase III. Hemolink (Hemosol): Being used for anemia trials and completed Phase III multicenter trial in the UK for CABG patients. The Brit’s were using Hemolink in Basra with some success. IO Gun EZ-IO™ from VidaCare™ is hand held battery powered device that provides fast, safe and controllable vascular access within seconds via the intraosseous route. The intraosseous space is a specialized area of the vascular system where blood flow is rapid and continues even during shock. Drugs and fluids infused via the intraosseous route reach the central circulation as quickly as those administered through standard IV access. EZ-IO™ is an alternative to failed emergency IV access. Plus…it’s another GUN and we like GUNS! 18 11/11/2013 Disability How often is C-Spine control and absolute? When there is no other choice but movement, how do you do it. Improvised C-Collars SAM Splint and Duct Tape Two items in every soldiers Pack or AID Bag! Exposure You have to look at everything NBC environments and medical operations Harsh tactical environment - VEST on or OFF Extremes in heat and cold Exceptions to all rules - Murphy’s Law! Asymmetric warfare. Follow-Up Constant reassessments of the patient, the scene, the situation Command and control with communication to higher is vital for a Doc’ in the field during treatment TELEMED is a viable option that is being refined daily…Fallujah experience. 19 11/11/2013 Pain Management Able To Still Fight – these medications are now carried by the soldier and can be self administered. Mobic, 15 mg po Qd. Tylenol, 650 mg bi-layer caplet, 2 PO every 8 hours. Pain Management Unable To Fight. Does not otherwise require IV/IO access. Oral transmucosal fentanyl citrate (OTFC), 800 mcg transbucally. Recommend taping lozenge on a stick to casualty’s finger as an extra safety measure. Reassess in 15 minutes – add a second lozenge and monitor for respiratory depression. Have naloxone readily available. Pain Management Ketamine 50 – 100 mg IM or 15-30 mg IV. Repeat dose every 30 minutes to 1 hour as needed to control severe pain or until the casualty develops nystagmus (rtythmic eye movement back and forth). Tactical considerations with Ketamine. TBI and IOP issue. Also – spontaneous utterances and jerking. Not good in a tactical setting. 20 11/11/2013 Pain Management Ketamine 50 mg intranasal (using a nasal atomizer device) Repeat the dose every 30 minutes to 1 hour as needed to control sever pain or until nystagmus develops. Pain Management IV or IO access obtained: Morphine sulfate, 5 mg IV/IO. Reassess every 5-10 minutes. Repeat dose every 5-10 minutes as necessary to control sever pain or until the casualty develops nystagmus. Monitor for respiratory depression and agitation. Promethazine, 25 mg IV/IM/IO every 6 hours as needed for nausea or for synergistic analgesic effect. Rules Change TC-3 Advances in pain management.
