Postoperative Patient with Suspected Bleeding
Signs: Tachycardia (earliest sign), hypotension, dropping Hb, increasing drain output (bloody), wound hematoma, altered mental status, oliguria, cool extremities.

Pathway Overview
15 steps
Algorithm Steps
15 total
01Start 02Action Rapid Assessment
1) ABC assessment - ensure airway/breathing stable. 2) Two large-bore IVs (if not present). 3) Type & Screen (crossmatch if not done). 4) STAT labs: CBC, coags (PT/INR/PTT/fibrinogen), lactate, BMP. 5) Check drain output, wound, surgical site. 6) Review operative report for bleeding risks.
03Decision Hemodynamic Status?
STABLE: SBP >90, MAP >65, HR <120, mentating, adequate UOP. UNSTABLE: Hypotension, tachycardia >120, altered mental status, poor perfusion, oliguria. SHOCK: SBP <80 or requiring vasopressors, unresponsive to initial fluids.
04Warning ⚠️ Don't Wait for Labs
In active hemorrhage, don't wait for lab results to initiate transfusion. Clinical signs are more important than Hb level. By the time Hb drops significantly, patient may be in late decompensated shock. Treat the patient, not the lab.
05Action Stable - Complete Workup
1) Serial H&H q4-6h. 2) Coagulation profile. 3) Consider CT angiogram if source unclear. 4) Ultrasound for hematoma assessment. 5) Hold anticoagulation. 6) Type & Crossmatch 4 units pRBC.
06Decision Bleeding Rate Assessment
Assess: Hb trend over 4-6 hours. Drain output rate. Transfusion requirement. SLOW: Hb stable or slow drop, drain output slowing. ONGOING: Continuous Hb drop, persistent high drain output, requiring repeated transfusion.
07Action Observation & Supportive Care
Bleeding appears self-limited. Serial Hb monitoring q6-8h. Transfuse for Hb <7 (or <8 if CAD). Correct coagulopathy. May resume prophylactic anticoagulation when stable. Continue monitoring for 24-48h.
08Action Post-Hemorrhage Control Care
1) ICU monitoring. 2) Serial labs to confirm stability. 3) Continue warming, correct electrolytes. 4) Mechanical VTE prophylaxis (hold anticoag until cleared by surgery). 5) Address anemia - may need further transfusion. 6) Debrief and document.
09Outcome Bleeding Controlled
Hemostasis achieved. Vitals stable. Continue postoperative recovery. Plan for DVT prophylaxis resumption.
10Action Coagulopathy Assessment & Correction
FFP for INR >1.5. Platelets for Plt <50K. Cryoprecipitate for fibrinogen <150. Vitamin K 10mg IV if warfarin. Prothrombin complex concentrate (PCC) for warfarin/factor Xa inhibitors. Idarucizumab for dabigatran. DDAVP for uremic bleeding or platelet dysfunction.
11Decision Source of Bleeding?
SURGICAL: Obvious wound bleeding, increasing drain output, hematoma. Often requires return to OR. COAGULOPATHIC: Oozing from all sites, no discrete source. Correct coagulopathy. MIXED: Common - both surgical bleeding and coagulopathy from blood loss.
12Decision Return to OR Indicated?
YES if: Hemodynamic instability despite resuscitation, ongoing transfusion requirement (>4-6 units), expanding hematoma threatening airway/compartment, clear surgical source, failure to respond to correction of coagulopathy. NO if: Bleeding controlled with correction of coagulopathy, stable vital signs, self-limited bleeding.
13Action Return to OR
1) Notify OR team - emergency case. 2) Continue resuscitation during transport. 3) Keep blood products infusing. 4) Intraoperative: Evacuate hematoma, identify source, achieve hemostasis. 5) Consider damage control if coagulopathic (pack, plan return). 6) ICU admission postop.

14Action Interventional Radiology
Consider angioembolization if: Discrete arterial source on CTA, patient stable enough for angio suite, suitable anatomy (hepatic, splenic, pelvic bleeding), IR available. Less invasive than reop for select cases. Not for rapid exsanguination.

15Action Unstable - Aggressive Resuscitation
1) Activate MTP (Massive Transfusion Protocol) if anticipated >10 units/24h. 2) Transfuse pRBC empirically (don't wait for labs). 3) Replace 1:1:1 ratio (pRBC:FFP:platelets). 4) Consider TXA (1g IV then 1g over 8h). 5) Calcium replacement (for citrate toxicity). 6) Keep patient warm.
