Why are opioid antagonists important?

Anesthesiologists rely on these agents for rapid reversal of adverse effects such as respiratory depression and loss of responsiveness. This may be especially important in the context of restoring ventilation in hypoxic patients either by antagonizing the ventilatory depressant effect of opioids or antagonizing the sedating properties of benzodiazepines so that patients can be prompted to breathe. Furthermore, select antagonists may also play an important role in other pathologic conditions, including tumor progression in selected types of cancer. This chapter will provide a brief overview of commonly used opioid and benzodiazepine antagonists. A summary of each reversal agent is presented in Table 7–1.

Does naloxone increase blood pressure?

For the anesthesiologist, naloxone is most often used to partially reverse opioid-induced sedation and respiratory depression. This is done by careful titration to desired effect. Naloxone has been used in some instances to increase blood pressure for several hours in patients with septic shock; however, improved survival has not been demonstrated. 1

Is naloxone an opioid?

Naloxone is a pure opioid antagonist. Although its mechanism of action is not fully understood, in vitro studies suggest that it competes for the μ, k, and σ opiate receptor sites of the central nervous system (CNS). When administered in the absence of opioid activity, it has no effect. 1

How long does it take for a reversal to occur?

If the patient needs fast, but not immediate, reversal, then FFP is generally used. For reversal that needs to occur within 6 hours, then patients may simply receive IV vitamin K (oral vitamin K works but it’s a lot slower…up to 24 hours).

How does naloxone work?

Naloxone reverses the effects of opioids by kicking the opioid off the receptor sites and binding them up for a period of time. The key thing you need to know about naloxone is that its duration of action is typically shorter than that of the opioid, so you need to monitor your patient closely and watch for signs of overdose to reappear. If they do, the patient may need another dose of naloxone. Naloxone can be given IV, IM, SubQ, in nebulized form or as a nasal spray. It can cause agitation, hypertension and even ventricular tachycardia in high doses.

How long does it take for warfarin to reverse bleeding?

Patients coming in with severe bleeding due to a warfarin overdose will get treatment based on the severity of the condition. If the patient has major bleeding, the general treatment guidelines as outlined in the Journal of Pathology include vitamin K and PCCs which are aimed at providing complete reversal within 15 minutes. If the patient needs fast, but not immediate, reversal, then FFP is generally used. For reversal that needs to occur within 6 hours, then patients may simply receive IV vitamin K (oral vitamin K works but it’s a lot slower…up to 24 hours).

Is Factor XA inhibitor a reverse agent?

Does protamine sulfate reverse heparin?

For overdoses of heparin and enoxaparain (which is a low-molecular weight heparin), protamine sulfate will reverse the anticoagulant effects. It acts as a heparin antagonist, but interestingly has a weak anticoagulant effect of its own as well. In fact, a study conducted in 2009 showed that it can actually cause increased bleeding, especially in patients who have undergone cardiothoracic surgery utilizing cardiopulmonary bypass. Protamine is given IV and comes with other serious side effects including hypotension and anaphylaxis reactions. For patient safety, it’s best to only give protamine with resuscitation equipment and treatment for anaphylaxis is within reach.

Why are opioids important to anesthesiologists?

Opioid and benzodiazepine antagonists are an important component of an anesthesiologists’ armamentarium. Anesthesiologists rely on these agents for rapid reversal of adverse effects such as respiratory depression and loss of responsiveness. This may be especially important in the context of restoring ventilation in hypoxic patients ...

What is the most rapid onset of action for opioids?

The most rapid onset of action is achieved by intravenous (IV) injection. Intramuscular (IM) or subcutaneous (SQ) injections are also possible but may have unreliable absorption patterns. Endotracheal administration is also an option when intravascular access is unavailable. Because the duration of action for many opioids is longer than that of naloxone, patients should be closely monitored following administration. 1

When was naloxone first used?

First synthesized in 1961, naloxone is indicated for the complete or partial reversal of opioid sedation and respiratory depression. It is also indicated for suspected opioid intoxication and has been proposed as an adjunctive agent in the management of septic shock. 1
