Unit 7 Rapid Response Debrief

[Instructor Name]

[Date]

The patient and all staff are composite and identified by role; times, doses and values are bracketed.

Timeline

1. [02:14], night nurse. Found Mrs. [L.] difficult to rouse; respiratory rate [6], saturation [82] percent on [2] liters, pupils pinpoint. Called rapid response.

2. [02:16], night nurse and charge nurse. Bag-mask ventilation with oxygen; saturation rising to [94] percent.

3. [02:18], rapid response team arrives: critical care nurse, respiratory therapist, AGACNP.

4. [02:19], AGACNP. Naloxone [0.04 mg] intravenously.

5. [02:21], AGACNP. Naloxone [0.04 mg] repeated; patient opening eyes to voice.

6. [02:23], respiratory therapist. Respiratory rate [12]; bag-mask stopped; nasal oxygen.

7. [02:25], critical care nurse. Point-of-care glucose [118] mg/dL.

8. [02:35], respiratory therapist. Arterial gas: pH [7.28], pCO2 [58] mmHg, pO2 [88] mmHg on [4] liters.

9. [02:40], AGACNP. Naloxone infusion started at [0.1 mg] per hour, because the respiratory rate began to fall again to [8] at [02:38]; scheduled morphine discontinued.

10. [02:52], team. Transfer to step-down with continuous capnography.

Recognition: The Event Began Before [02:14]

The rapid response was called at [02:14], but the conditions for it were present hours earlier.

Mrs. [L.] had received morphine [4 mg] intravenously every [four] hours on a schedule since surgery, plus as-needed doses for pain. On the morning of [Day 2], her creatinine was [2.1] mg/dL, up from [0.9] before surgery, after a period of low blood pressure in the operating room. The result was reviewed and fluids were increased, but the morphine order was not changed. Morphine is broken down to metabolites, including morphine-6-glucuronide, that are cleared by the kidneys and accumulate when kidney function falls; the active metabolite adds to sedation and respiratory depression (Dean, 2004). When the creatinine doubled, every scheduled dose of morphine became a larger dose, even though the order did not change.

At [22:00], the evening nurse recorded a Pasero Opioid-Induced Sedation Scale score of 3: frequently drowsy, arousable, drifting off to sleep during conversation. On that scale, a score of 3 is unacceptable and calls for holding or reducing the opioid and increasing monitoring (Pasero, 2009). The as-needed morphine was held, but the scheduled [midnight] dose was given, because the order was scheduled rather than as needed. Respiratory rate at [22:00] was [12], and saturation was [95] percent on [2] liters, which may have been reassuring.

Response: What Went Well

The response itself was fast and effective. The nurse recognized opioid toxicity, supported breathing with a bag-mask before the team arrived and called early. The team gave naloxone in small, repeated doses, which reversed the respiratory depression without causing sudden, severe pain or agitation in a patient two days after spine surgery. They checked glucose to exclude another cause, measured the carbon dioxide, recognized that the naloxone's effect was wearing off before the morphine's, and started an infusion. Transfer with continuous capnography was the right level of monitoring.

Why Small Doses of Naloxone

The choice of [0.04 mg] rather than a full [0.4 mg] dose deserves a comment, because it is the decision most often questioned after an event like this. A full dose would have reversed the respiratory depression more quickly, but it would also have reversed her analgesia completely, two days after spine surgery. Sudden, severe pain after abrupt reversal can cause agitation, a surge in blood pressure and heart rate and, in some patients, pulmonary edema. Because she was being ventilated with a bag-mask and her saturation had recovered, there was time to titrate. Small repeated doses restored her breathing within four minutes while leaving her some pain control. The infusion followed because naloxone wears off in less than an hour, and the morphine metabolites accumulated in her body would outlast it for many hours with her kidney function.

How the Debrief Was Held

The debrief took place at [03:30] at the nurses' station, lasted [15] minutes and brought together everyone who had been at the bedside, along with the covering clinician. It followed a simple order: what happened, what went well, what could be improved, and what each person would take away. The facilitator, the critical care nurse, began by thanking the night nurse for calling early and ventilating before help arrived, which set a tone in which the evening nurse, who had given the midnight dose, could describe her reasoning openly. That openness is what allowed the scheduled order, rather than any individual, to be identified as the problem.

Contributing Factors

1. Drug and kidney: a scheduled opioid with renally cleared active metabolites continued after a doubling of creatinine.

2. Order design: the order set allowed scheduled intravenous morphine without a built-in review when kidney function changed.

3. Monitoring: pulse oximetry on supplemental oxygen can remain normal while carbon dioxide rises, which delays detection; capnography was not in use on the surgical ward.

4. Escalation: a sedation score of 3 led to holding as-needed doses but did not prompt a call to review the scheduled order.

5. Patient factors: age [79], low body weight and a first surgery requiring opioids.

The pain management nursing society's monitoring guideline identifies advanced age, renal impairment and the first 24 to 48 hours after surgery as periods of higher risk, and recommends sedation assessment alongside respiratory monitoring, with capnography considered for high-risk patients (Jarzyna et al., 2011). Mrs. [L.] met all three.

Recommendations

1. Pharmacy: automatic review of scheduled opioid orders when creatinine rises by 50 percent or more.

2. Prescribers: avoid scheduled morphine in older adults with changing kidney function; prefer agents without active renally cleared metabolites, at reduced doses, and as-needed rather than scheduled when possible.

3. Nursing: a sedation score of 3 triggers a call to the prescriber to review all opioid orders, scheduled and as needed.

4. Monitoring: continuous capnography for postoperative patients on intravenous opioids who meet two or more risk criteria.

5. Education: a brief review at the surgical ward's next huddle, using this case with identifiers removed.

Outcome

Mrs. [L.] stayed on step-down for [24] hours. The naloxone infusion was stopped at [10:00] the next morning. Her pain was managed with scheduled acetaminophen, a reduced dose of hydromorphone as needed, and physical therapy. Her creatinine returned to [1.2] by [Day 5]. She and her family were told what happened, and a safety report was filed the same morning by the night nurse.
