Reversal of Opioid Sedation

Reversal of Opioid Sedation – General Information

In general, the sedation procedure usually consists in administrating certain sedative agents, in most cases to facilitate a surgical approach with local anesthesia. There are also some cases in which the doctors apply sedation using opioids – this is more common in certain medical procedures such as endoscopy, vasectomy or other minor surgery, and especially in dentistry for reconstructive procedures, certain cosmetic surgeries, removal of impacted wisdom teeth, or, in rare cases, for advanced stages of anxiety. There are some sedative methods that are commonly used by doctors; they include inhalation sedation with nitrous oxide, oral sedation or intravenous sedation. These procedures are applied in a safe intensive medical unit, where the patient is being ventilated with the help of an endotracheal tube inserted in his or her trachea.

There are certain levels of sedation, depending on the severity of the patient’s disease. In some cases, if the sedation was not administered properly, the individual experiences under sedation (he or she is exposed to pain or distress), and / or over sedation (he or she risks experiencing some severe side effects such as suppression of breathing, which eventually cause death). In general, the levels of this medical procedure are: agitation, calm, responsiveness to voice only, responsiveness only to shaking, responsiveness only to pain and not responsive. Reversal of Opioid Sedation is generally made by administrating certain reversal agents such as Naloxone, Narcan, Flumazinil and Romazicon, which act by reversing the effects of the sedation procedure. In Reversal of Opioid Sedation it is important to administrate these medicines properly in order to prevent complications and the present of harmful side effects.

Reversal of Opioid Sedation – Symptoms

It is very important for the doctor to follow a set of critical steps in administrating the sedative medicines to the patient, in order for the medicines to create a decreased level of awareness for the individual but to maintain the protective airways reflexes and a proper spontaneous ventilation. The goals of the sedation procedure are to provide analgesia, amnesia and anxiolysis during a surgical procedure that can cause pain to the patient. The doctor has to perform some procedures before administrating sedative agents, which can include debridement of wounds, placement of central lines, chest tube placement, abscess drainage, reduction of fractures and dislocations.

In general, agents used in Reversal of Opioid Sedation should not be used due to appropriate titrate of the sedative agents. The reversal medicines are in most of the cases applied at the same time with the sedative medicines in order to reduce the risk of developing side effects or more significant complications. There are certain cases in which the patient can be allergic to these medicines and if they are applied without knowing this fact, it can cause chronic allergic reactions that can cause death. The most common side effects caused by the medicines applied in Reversal of Opioid Sedation can be experienced as nausea and vomiting, sweating, increased heart rate, hyperventilation, increased blood pressure, reversal of pain relief if larger doses are used, irregular hear beat, low blood pressure, and accumulation of fluid in the patient’s lungs. It is very important to tell to the doctor about these effects so he can treat them in an early stage, in order to avoid other more severe complications.

Reversal of Opioid Sedation – Treatment

In general, doctors use a high diversity of medicines that act as reversal agents for sedative procedures, which can usually include narcotics and a certain type of sedative agents. If the doctor uses narcotics and benzodiazepines as sedative agents, to reverse their effects, there are specific reversal agents for these types of medicines. If the patient has been treated with narcotics, the most common medicine in improving Reversal of Opioid Sedation is considered Naloxone or Narcan, but if the patient has been treated with benzodiazepines, the most common reversal agent used is Flumazinil or Rumazicon. Naloxone is considered a pure opioid antagonist which acts by preventing or reversing the effects of opioids, which can include respiratory depression, sedation, and hypotension, by direct competition at kappa and sigma opioid receptor binding sites.

Usually, the Naloxone medicine reverses both exogenous and endogenous opioids, such as endorphins, enkephalins, and dynorphins. This kind of medicine is used especially as a reversal agent for opioid sedation; that is why in the absence of opioids, the Naloxone medicine has little to nothing pharmacologic effect. There are cases in which the patient is diagnosed as being apneic, and in these cases most of the doctors apply a dose of 0.4 mg or 1 ampule of the Naloxone medicine, administered usually intravenously or intramuscularly in addition with close monitoring. Doctors, as treatment medicine for Reversal of Opioid Sedation, can prescribe the Naloxone medicine under several trademarks including Narcan, Nalone and Narcanti. There are cases in which patients confuse the medicine with the naltrexone drug, which is usually applied for dependence treatment rather than emergency overdose treatment. If the medicine is not administered properly it can cause significant side effects and complications such as pulmonary edema and hypertension.

Another important fact about Reversal of Opioid Sedation is that the patient can easily narcotize because the half life of Naloxone is only twenty minutes and the half life of certain narcotics is way longer than that. Another medicine used in Reversal of Opioid Sedation is Nalmefene. This kind of medicine is used to treat narcotic overdose or other situation in which the patient experiences opioid side effects. It is very important for the doctor to know if the patient suffers from liver or kidney disease, heart disease, for which he is following a certain therapy, before he receives the Nalmefene treatment. The intake of this kind of medicine also differs if the patient is pregnant or breast feeding. The Nalmefene medicine is administrated intramuscularly, through an injection that is usually performed in a hospital or emergency setting. There are cases in which the medicine can cause certain side effects such as extreme drowsiness, weak or shallow breathing, chest pain or fluttering in the patient’s chest, feeling of passing out, nausea, vomiting, stomach pain, muscle or join pain, chills and feeling of anxiety and depression. Another medicine used in Reversal of Opioid Sedation is Romazicon, an agent indicated for complete or partial effects of benzodiazepine sedatives, particularly in cases where complete anesthesia has been applied and maintained with benzodiazepines, or if the diagnosing procedures has been supported by these sedatives.
