Anticoagulation, a DNR Order, and a Documented Refusal of Blood Products

The date cannot be confirmed as safe yet, and that is the first finding to escalate.

• Apixaban half-life is roughly 12 hours, and it lengthens with renal impairment (CrCl 42). For a procedure carrying meaningful bleeding risk, typical practice is to hold apixaban for at least 48 hours before incision, and many protocols extend the hold to 72 hours when CrCl is below 50. With a last dose this morning and surgery in 3 days, the numbers may work, but it depends on the exact timing of the last dose relative to incision and on the surgeon's own bleeding-risk assessment - do not sign off on it.
• Bridging is not indicated for direct oral anticoagulants in most perioperative scenarios; the question to ask is the hold interval, not whether to start lovenox.
• Verify, do not assume: the exact date and time of the last dose, the prescribed dose versus the renal-adjusted dose (5 mg BID is the standard dose; the reduced dose is 2.5 mg BID and requires two of three criteria - age ≥80, weight ≤60 kg, creatinine ≥1.5 - which this patient may or may not meet), renal function recheck, and whether the prescribing cardiologist wants input.
• Escalate to the surgeon and anesthesia with the CrCl and the timing, and confirm the plan in writing before the patient is told to come in.

Reasoning principle: the CSFA's job is to make the ambiguity visible. "She's been told to hold it" is not the same as "the hold interval matches this patient's renal function and this procedure's bleeding risk."

A DNR order cannot simply be carried unchanged into an anesthetized patient, and it cannot simply be ignored. It requires a documented reconsideration.

• Why: much of what constitutes resuscitation - positive pressure ventilation, vasoactive drugs, chest compressions for a vagal or embolic event - is a routine, expected part of general anesthesia. Applying an unmodified DNR to the OR can produce a situation where the anesthesia team is required to withhold treatment that is integral to the anesthetic the patient consented to.
• Process: the surgeon and/or anesthesia should discuss with the patient (she has capacity and decides for herself) which interventions she would and would not accept in the perioperative period specifically - for example, accepting intubation, fluids, and vasopressors while refusing prolonged CPR or ICU escalation. The resulting plan is written as a specific, time-limited perioperative order, with the original directive preserved.
• The CSFA's role: confirm that this conversation is documented and current, flag its absence to the surgeon before the day of surgery, and make sure the perioperative plan is visible on the chart and known to the OR team.

Reasoning principle: the goal is not to suspend autonomy but to make the patient's actual wishes explicit for a context she may not have anticipated when the directive was written.

Before the case proceeds:

• Confirm the refusal is valid and specific: the patient has capacity, the directive is signed and current, and it has been discussed with her directly - not just filed. Document her own words about what she does and does not accept.
• Establish the blood conservation plan in advance, not in a crisis: anemia workup and iron optimization now, tranexamic acid per protocol, meticulous hemostasis, cell salvage only if she has been asked and agrees (some patients in this faith accept cell salvage when continuity of the circuit is maintained, others do not - do not assume either way), tolerance of lower hemoglobin thresholds, and a defined escalation path if bleeding exceeds expectation.
• Notify the blood bank and anesthesia so the plan is known and so resources are not mobilised against her wishes. Confirm the surgeon is willing to operate under these constraints - that is a consent issue, and it belongs to the surgeon.

On the comment: "nobody really needs a hernia repair" is the wrong frame. The patient's autonomy does not depend on whether the surgeon expects to transfuse, and a case planned at under 100 mL can still bleed. The correct response is professional, not confrontational: "Her refusal is documented - can we confirm the conservation plan and that she has been consented for surgery under those constraints?"

Reasoning principle: an expected-low-blood-loss case is exactly when the plan is cheap to make and exactly when a surprise bleed turns an unaddressed refusal into an emergency ethics problem.
