The Unstable Polytrauma Patient at a District Hospital: Damage-Control Decisions

A 34-year-old motorcyclist arrives at a district hospital 40 minutes after a high-speed collision. He is alert but restless. Blood pressure is 84/48 mmHg, heart rate 132/min, respiratory rate 28/min, SpO2 91% on 10 L oxygen, temperature 35.4 °C. He has an open right femoral shaft fracture (Gustilo–Anderson IIIA) that is oozing, a clinically unstable pelvic ring with a palpable gap and expanding haematoma, and left-sided rib fractures with a pulmonary contusion. He has already received 3 units of packed red cells and 3 units of fresh frozen plasma through a rapid infuser, plus tranexamic acid 1 g. Arterial lactate is 6.8 mmol/L, base deficit −9 mmol/L, pH 7.22, haematocrit 22%, INR 1.6, and ionised calcium is low. A pelvic binder is in place. The hospital has a staffed general theatre and an orthopaedic trainee, but the major trauma centre with interventional radiology and a consultant-led 24-hour service is 2.5 hours away by road, the helicopter is grounded by weather, the district has no intensive care bed, and only 2 units of red cells remain in the blood bank.

1. What are your priorities in the first 60 minutes, and what is your operative plan? Explain why you would not simply transfer him for pelvic angiography.

The first priority is control of exsanguinating haemorrhage, not the femur. The pelvic binder must sit at the level of the greater trochanters rather than the iliac crests, which is a common error that leaves the pelvis open. I would activate the local massive transfusion protocol with a balanced 1:1:1 ratio, give calcium for the low ionised calcium, actively warm him, and continue tranexamic acid. Permissive hypotension to a systolic pressure of 80–90 mmHg is reasonable here only because there is no lateralising neurology and the GCS is 14; with any suspicion of head injury I would target a systolic pressure above 90–100 mmHg. A FAST scan decides the next move: free fluid means immediate laparotomy by the general surgeon.

If the FAST is negative, the pelvis is the probable source. Angioembolisation is the best option in theory but not in practice here: 2.5 hours of road transfer, no ICU bed, low blood stock and no retrieval team means he would most likely arrest in transit. The correct judgement is damage-control surgery on site: preperitoneal packing plus an anterior external fixator for the pelvis, and, in the same anaesthetic, wound debridement with external fixation of the open femur rather than intramedullary nailing. Antibiotics (cefazolin plus gentamicin for a grade IIIA wound) and tetanus cover should follow cultures and be given before incision. Crystalloid should be restricted, and I would not send him for a CT scan until physiology is corrected.

After haemostasis, the priority is retrieval to the major centre within 24 hours, accepting that definitive pelvic and femoral fixation will be delayed. Every step should be documented and communicated to the family, because the decision is one of life over limb.

2. On day 3 he is in the district unit, intubated, with lactate 1.8 mmol/L, temperature 36.9 °C, platelets 95 × 10⁹/L, INR 1.3, and noradrenaline 0.05 µg/kg/min. The fixator is stable and the open wound is clean. How do you decide whether to convert to intramedullary nailing now, and what is the reasoning behind your choice?

He is still in the borderline/in-extremis zone: he requires a vasopressor, his platelets remain below 100 × 10⁹/L and his INR is mildly deranged, even though his lactate has cleared. The concept that matters is the second hit. Reaming and nailing a femur causes a systemic inflammatory surge, and in a patient with a pulmonary contusion this can tip him into ARDS and multiple organ failure.

The clinical parameters that would allow early total care are: lactate under 2 mmol/L, base deficit better than −4 mmol/L, normothermia above 35 °C, normal coagulation, no vasopressor requirement, and adequate urine output. He currently fails at least three of these. My decision would therefore be to continue damage-control orthopaedics, return to theatre only for a planned second look and wound debridement at 48 hours, and convert to a nail when the noradrenaline has been off for 24 hours, platelets are recovering and the inflammatory markers are trending down, usually between days 5 and 8. If the patient were a good responder who cleared his lactate and came off vasopressors within 24 hours, early total care within the first day would be preferable and evidence-supported.

The trade-off should be explicit to the team: a longer period in an external fixator increases pin-site infection, pneumonia, delirium and venous thromboembolism, and consumes nursing resources. That risk is still lower than the mortality of provoking a second hit in a contused lung. The family should be told that the external fixator is temporary and that the plan may change daily.

3. Before he leaves the district hospital, what must be checked, and what prophylaxis and follow-up would you arrange?

The secondary survey is the main gap in these patients. I would systematically exclude: an unstable cervical spine, thoracic aortic injury, diaphragmatic rupture, urethral or bladder injury (a pelvic fracture with a gap, so a retrograde urethrogram before any catheter), and compartment syndrome in the contralateral limb. Complete imaging at the major centre should include a whole-body CT and a formal pelvic series, and the open wound should be photographed and documented.

Venous thromboembolism prophylaxis should start with low-molecular-weight heparin once haemostasis is secure, usually 24–48 hours after packing and fixation, and with mechanical prophylaxis in the interim; he has no head injury, so there is no reason to defer for more than 48 hours. Antibiotics for the open fracture should stop within 24 hours of the last adequate debridement, not be continued for weeks.

Nutrition, analgesia, delirium screening and pressure-area care matter as much as the surgery. I would set out a written plan: repeat debridement timing, date for conversion to definitive fixation, weight-bearing restriction on the pelvis, and a rehabilitation referral for the knee and hip. Retrieval should be in an equipped ambulance or with a critical-care team, not unaccompanied.

Finally, the delay in access to definitive care is a system issue. I would document it, raise a formal incident report and audit the time from presentation to pelvic fixation, because the same scenario will recur and the next patient may not have 2 units of blood left in the bank.
