JTS TCCC Guidelines · 2025 Ranger Medic Handbook · Prolonged Casualty Care Guidelines
The Five Schedules
The Drug Enforcement Administration classifies controlled substances into five schedules. Abuse potential decreases as the schedule number increases. Schedule I has the highest abuse potential and no accepted medical use. Schedule V has the lowest abuse potential and routine medical use.
| Schedule | Examples | Abuse Potential | Medical Use | Dependence |
|---|---|---|---|---|
| Schedule I | Heroin, LSD, marijuana, Ecstasy (MDMA) | High | None accepted; research, analysis, or instruction only | — |
| Schedule II | Morphine, meperidine (Demerol), fentanyl (Actiq), codeine, oxycodone, opium, amphetamines | High | Accepted | May lead to severe physical and/or psychological dependence |
| Schedule III | Buprenorphine (Suboxone), acetaminophen with codeine (Tylenol #3), ketamine (Ketalar), anabolic steroids | Less than Schedule I and II | Accepted | Moderate or low physical dependence, or high psychological dependence |
| Schedule IV | Midazolam (Versed), alprazolam (Xanax), zolpidem (Ambien) | Lower than Schedule III | Accepted | Limited physical or psychological dependence |
| Schedule V | Diphenoxylate (Lomotil), guaifenesin and codeine (Robitussin AC) | Lower than Schedule IV | Accepted | Limited physical or psychological dependence |
Phases of TCCC
Four TFC / TACEVAC Medication Categories
| Category | Purpose |
|---|---|
| Pain | Combat Wound Medication Pack, fentanyl, ketamine |
| Bleeding | Tranexamic acid (TXA); calcium gluconate or calcium chloride after blood products |
| Infection | Cefazolin, metronidazole, moxifloxacin, ertapenem, ceftriaxone |
| Other | Naloxone, ondansetron, promethazine, midazolam, epinephrine, diphenhydramine, lidocaine |
The Decision Tree
JTS TCCC triages pain treatment by two questions. First, how severe is the pain? Second, what is the casualty’s physiological status? The combination produces three options.
| Option | Pain Level | Casualty Status | Treatment |
|---|---|---|---|
| Option 1 | Mild to Moderate | Still able to fight | TCCC Combat Wound Medication Pack (CWMP) |
| Option 2 | Mild to Moderate | NOT in shock or respiratory distress AND NOT at risk of developing either | Oral transmucosal fentanyl citrate, or fentanyl IN, or fentanyl IV |
| Option 3 | Moderate to Severe | IS in shock or respiratory distress, OR at significant risk of developing either | Ketamine IN, IM, IV, or IO |
Option 1 — Combat Wound Medication Pack (CWMP)
- Acetaminophen (Tylenol) — 500 mg tablet, 2 PO every 8 hours.
- Meloxicam (Mobic) — 15 mg PO once daily.
Option 2 — Fentanyl
- Oral transmucosal fentanyl citrate (Actiq) — 800 micrograms.
- Fentanyl (Sublimaze) intranasal — 100 micrograms.
- Fentanyl (Sublimaze) intravenous — 50 micrograms, or 0.5 to 1 microgram per kilogram.
Directions for OTFC Lozenge
Option 3 — Ketamine
- Ketamine (Ketaset) IN or IM — 50 to 100 mg, or 0.5 to 1 mg per kilogram.
- Ketamine (Ketaset) slow IV or IO push — 20 to 30 mg, or 0.2 to 0.3 mg per kilogram.
The Three Severity Tiers
The Ranger Medic Handbook uses a numeric pain scale rather than the binary mild-moderate / moderate-severe split used by JTS TCCC. The tiers are 1–3 (mild), 4–6 (moderate), and 7–10 (severe).
Mild Pain (1–3) — Casualty Still Able to Fight
Use the Combat Wound Pill Pack: Tylenol 1,000 mg PO single dose AND Mobic 15 mg PO single dose. Consider as alternatives:
- Ibuprofen — 600 mg PO three times daily.
- Naproxen — 250 to 500 mg twice daily.
- Ketorolac — 30 mg IM, or 15 mg IV, twice daily.
Moderate Pain (4–6) — NOT in Shock or Respiratory Distress
Casualty is not at risk of developing shock or respiratory distress. Consider:
- Fentanyl lozenge — 1600 micrograms PO as needed.
- Ketamine — 0.1 to 0.3 mg per kilogram IV or IO, or 0.5 mg per kilogram IM or IN, every 30 minutes as needed.
- Hydromorphone — 0.25 to 0.5 mg IV or IO every hour as needed.
Severe Pain (7–10) — IS in Shock or Respiratory Distress or At Risk
- Ketamine — 0.1 to 0.3 mg per kilogram IV or IO, or 0.5 to 1 mg per kilogram IM or IN, every 30 minutes as needed.
- Hydromorphone — 0.5 to 1 mg IV or IO every 30 minutes as needed; titrate to effect.
- Fentanyl — 0.5 to 1 microgram per kilogram IV or IO every 30 minutes as needed.
Adjuncts (All Tiers)
- Midazolam — 2 to 5 mg IV with ketamine or opioids for anxiolysis or sedation.
- Ondansetron — 8 mg IV, IM, or sublingual every 8 hours as needed for nausea or vomiting.
- Consider a nerve block for extended evacuation times and drug-limited environments.
- Reassess pain and titrate dosage as needed.
Core Rules
- Casualties must be disarmed after being given OTFC, intravenous fentanyl, ketamine, or midazolam.
- The goal of analgesia is to reduce pain to a tolerable level while still protecting the airway and mentation.
- The goal of sedation is to stop awareness of painful procedures. Sedation is Option 4 for pain control and is taught during Prolonged Field Care in Trauma 3.
- Document a mental status exam using the AVPU method (Alert, Verbal, Painful, Unresponsive) before administering opioids or ketamine.
- Use caution with these drugs in traumatic brain injury patients. They make it harder to perform a neurologic exam or detect decompensation.
If Respirations Drop
Benzodiazepines — What Not to Do
- The routine use of benzodiazepines such as midazolam (Versed) is NOT recommended for analgesia.
- Benzodiazepines should not be used prophylactically.
- They are not commonly needed when the correct pain or sedation dose of ketamine is used.
- Polypharmacy is not recommended. Benzodiazepines should NOT be used in conjunction with opioid analgesia.
Monitoring
For all casualties given opioids, ketamine, or benzodiazepines, monitor airway, breathing, and circulation closely.
Indications for TXA
Administer tranexamic acid if a casualty meets either of the following criteria.
- Will likely need a blood transfusion. Examples: hemorrhagic shock, elevated lactate, one or more major amputations, penetrating torso trauma, or evidence of severe bleeding.
- Has signs or symptoms of significant traumatic brain injury, or has altered mental status associated with blast injury or blunt trauma.

Infection Control CPG Key Principles
- Standard Precautions — hand hygiene and personal protective equipment.
- Surgical Site Infection (SSI) Prevention — prophylactic antibiotics preoperatively, proper skin preparation, postoperative monitoring.
- Open Wound Management — control bleeding, apply sterile dressings, ensure appropriate follow-up.
Cefazolin (Ancef) — The Default
Dose: 2 grams IV every 6 to 8 hours. Indicated for:
- Penetrating brain injury
- Open maxillofacial fractures
- Maxillofacial fractures WITH foreign body or fixation device
- Penetrating chest injury without esophageal disruption
- Penetrating spinal cord injury
- Skin and soft tissue, no open fractures
- Skin and soft tissue, WITH open fractures, exposed bone, or open joints
Cefazolin AND Metronidazole — When Anaerobic Coverage Is Needed
Add metronidazole (Flagyl) 500 mg IV every 8 to 12 hours to cefazolin for:
- Penetrating brain injury if gross contamination with organic debris
- Penetrating chest injury with esophageal disruption
- Penetrating spinal cord injury if the abdominal cavity is involved
- Penetrating abdominal injury with suspected or known hollow viscus injury and soilage; rectal or perineal injuries
Expected Delay to Reach Surgical Care — Oral Option
| Drug | Dose | Route |
|---|---|---|
| Moxifloxacin (Avelox) | 400 mg | PO x 1 dose |
Use moxifloxacin PO if the casualty can tolerate oral medications and does NOT have penetrating abdominal injury or shock.
Expected Delay — IV/IM Options
| Scenario | Drug | Dose | Route |
|---|---|---|---|
| Penetrating abdominal injury, shock, or unable to tolerate PO | Ertapenem (Invanz) | 1 gram | IV or IM |
| Penetrating head injury, shock, or unable to tolerate PO | Ceftriaxone (Rocephin) | 1 to 2 grams | IV or IM |
Opioid Reversal
| Drug | Dose | Route | Use |
|---|---|---|---|
| Naloxone (Narcan) | 0.4 mg | IV, IO, or IM | Reverse opioid-induced respiratory depression |
Nausea and Vomiting
| Drug | Dose | Route |
|---|---|---|
| Ondansetron (Zofran) | 4 mg | Oral disintegrating tablet, IV, IO, or IM |
| Promethazine (Phenergan) | 12.5 to 25 mg | PO, IV, or IM |
Sedation / Anxiolysis
| Drug | Route | Note |
|---|---|---|
| Midazolam (Versed) | IN, IO, IV, or IM | NOT for analgesia. Used for sedation or seizure. Not given alongside opioids. |
Anaphylaxis
| Drug | Route | Role |
|---|---|---|
| Epinephrine (Adrenalin) | IM | First-line. Reverses bronchospasm and hypotension. |
| Diphenhydramine (Benadryl) | PO, IV, or IM | Antihistamine adjunct. Does not replace epinephrine. |
Local Anesthesia
| Drug | Route |
|---|---|
| Lidocaine (Xylocaine) | IV or IM |
MARC²H³-PAWS-L
The PCC framework expands MARCH with additional priorities for situations where evacuation is delayed.
| Letter | Meaning |
|---|---|
| M | Massive Hemorrhage / MASCAL |
| A | Airway |
| R | Respirations |
| C | Circulation |
| C | Communication |
| H | Hypothermia / Hyperthermia |
| H | Head Injury |
| P | Pain Control |
| A | Antibiotics |

Highlights — What Changes from TCCC
- MASCAL — PCC events often start with multiple casualties combined with lack of evacuation resources.
- Nursing Care — not a traditional combat medic skill, but a vital component of PCC.
- Communication — important in TCCC, even more important across larger times and distances and for ICU-level patients.
- Logistics — almost always a problem. Requires contingency planning and creative thinking.
The 13 Steps of PCC
PCC Pain Management — Non-Opioid Tier
| Drug | Dose / Route | Onset | Duration | Side Effects |
|---|---|---|---|---|
| Acetaminophen | 1 gram PO, IV when given IV | 15 to 60 min | 4 to 6 hours | Allergic reaction (rare); liver damage with high doses |
| Meloxicam | 15 mg PO once daily | 15 to 60 min | 4 to 6 hours | Reflux, abdominal pain, nausea, vomiting, diarrhea, possibly constipation |
| Tramadol | 1 to 2 tabs PO every 4 to 6 hours; max 400 mg/day | 30 to 60 min | 4 to 6 hours | Drowsiness, respiratory depression, sedation, nausea, vomiting, itching, CNS stimulation including seizures at high dose |
| Codeine / Acetaminophen | 1 to 2 tabs PO every 4 to 6 hours | 30 minutes to 1 hour | 4 to 6 hours | Drowsiness, respiratory depression, sedation, nausea, vomiting, itching |
PCC Pain Management — Opioid Tier
| Drug | Dose / Route | Notes |
|---|---|---|
| Fentanyl | OTFC 800 mcg buccal, or 0.5 to 1 mcg/kg IV/IO/IN every 30 min PRN | Respiratory depression, nausea |
| Hydromorphone | 0.5 to 1 mg IV/IO every 30 min PRN; titrate to effect | Respiratory depression with rapid push; sedation |
| Ketamine | 0.1 to 0.3 mg/kg IV/IO or 0.5 to 1 mg/kg IM/IN every 30 min PRN | Hypersalivation, can be paired with midazolam to reduce emergence reactions |
| Midazolam | 2 to 5 mg IV with ketamine or opioids | For anxiolysis or to manage ketamine emergence; respiratory depression risk increases when combined |
PCC Antibiotics — Alternative Selections by Injury
If transitioning from ertapenem (Invanz) to moxifloxacin, begin moxifloxacin immediately after the final dose of ertapenem for antibiotic overlap. If using moxifloxacin only, administer 400 mg PO daily for 10 days. If using ertapenem only, administer 1 gram IV or IO or IM daily for 10 days.
