Responding to an Opiate Overdose BIOLOGY OF TOXINS SPRING 2012 MARY MURPHY, SARAH COOK, AND GILBERT ORNELAS Introduction More than 70 people die a day in the United States from drug overdoses. New Mexico has the highest overdose death rates* of any state, with Bernalillo and Rio Arriba counties’ overdose death rates exceeding that of both Los Angeles and New York. Many of these deaths resulted from opiate use. It is an epidemic of unnecessary tragic deaths but there is an antidote… *Death rate is defined as deaths per 100,000 people over a year period. What is an opiate? the term opiate describes any of the narcotic opioid alkaloids found as natural products in the opium poppy plant a drug containing opium or its derivatives, used in medicine for inducing sleep and relieving pain any sedative, soporific, or narcotic with morphine like effects anything that causes dullness or inaction or that soothes the feelings What are Opiate Receptors? They are a group of Gprotein coupled receptors with opioids as ligands. The endogenous opioids include: dynorphins, enkephalins, endorphins and nociceptin. These receptors are found primarily in the brain but also in the spinal chord and the digestive tract. Examples of Common Opiates Heroin “chiva” Oxycontin (oxycodone) “oxys” Percocet (oxycodone) “perks” Demerol (mepiridine) Vicodin (hydrocodone) “hydros” morphine codiene Fentanyl Methadone The risks associated with opiate use apply to medications prescribed legally by a physician as well as illicit drugs. Heroin was invented by Bayer as a painkiller and was a treatment for morphine addiction. Many of the legal opiates available now are considered as addictive as Heroin. Legal does not equal safe. What is an Overdose? when a person has a greater effect than anticipated from a substance they have taken into their system getting the jitters from too much coffee or energy drinks chewing tobacco for the first time and feeling nauseated in the case of opiates this could mean getting “too high” or even stopping breathing Common Symptoms of Opiate Overdose Unconscious/ passed out Unresponsive Shallow or no breathing Skin turning pale or blue Making choking and gasping sounds Snoring Limp body or lack of muscle tone Cold to the touch Awake but unable to speak Vomiting (This is not intended to be a comprehensive list and a person experiencing an opiate overdose may not exhibit every one of these symptoms.) What Causes an Opiate Overdose? 1. Mixing Drugs 2. Lowered Tolerance 3. Changing Drug Concentration 4. “Solo Drugs” 1. Mixing Drugs Mixing drugs is the most common cause of death by opiate overdose – the fewer drugs someone takes the less likely they are to die of an overdose. Mixing drugs with alcohol as another way that people can have an overdose. If a person uses drugs and they are unprepared to stop, perhaps they can consider only using one or two drugs. 2.Lowered Tolerance Lowered tolerance can be caused by: If a person who uses opiates has not been using for even a day tolerance can decrease. Opiate users exiting rehab, hospitalization and jail are at much higher risk for overdose if they relapse. Lowered tolerance can also be the result of not taking in enough food or water, having an illness, or not having enough sleep. An inexperienced (new) drug user will have a low tolerance. 3.Changing Drug Concentration Illicit drugs do not always come in standardized strengths. A person can have a opiate overdose as a result of acquiring Heroin from a new dealer or a dealer getting a new batch. A person should use caution if trying a drug for the first time or trying a new batch of drug for the first time. For example: the 'China White' type of Heroin is a great deal more potent than the ‘Black Tar' typically found in New Mexico. When 'China White' appears in New Mexico it is always followed by an increase in opiate overdoses. 4. “Solo Drugs” Using opiates alone is a cause on unnecessary opiate overdose death. If a person is using opiates when no one is around, there is nobody there to rescue them if they stop breathing. Even Though Overdoses are Scary: Do not hit the person who overdosing Do not inject them with drugs or breath drugs into their lungs Do not abandon the person who is overdosing Try not to panic Other Potentially Dangerous Responses Are: Placing ice or bags of frozen green chili on the groin Putting the person in a shower or in the river Electrocuting the person What Can you do? Help them walk around if they are conscious Ask the person to breathe more deeply If they are unconscious: Do a sternal rub (rub knuckles on bone in chest – will cause pain, not injury) 2. Call 911 3. Breathe for the person (opiate overdose deaths result from oxygen starvation) 4. Administer the antidote (naloxone) 1. 1. Sternal Rub A sternum rub can sometimes help to revive an overdose victim. Making a fist, you rub your knuckles into the sternum and the center of the person's chest. It is intended to be painful and can cause bruising. However, it is an excellent alternative to hitting the person because it is less harmful and may achieve the purpose of getting the person to respond. 2. Calling 911 Try to stay calm Try to keep the background of the phone call sounding calm Tell 911 that someone is unconscious and not breathing (you don't have to mention drugs) Give 911 good directions to where you are Stay with the person and breathe for them as long as you can Stay long enough to make sure the ambulance is headed to the right place If you have to leave the person for some reason, leave them in the rescue position and leave the door open to where you were If you administer naloxone, and you have to go, leave the vial nearby so the EMTs will see that you already gave some The Rescue Position If you have to leave someone who is unresponsive alone to go for help, leave them in The Rescue Position. The Rescue Position decreases the likelihood that they will choke if they vomit. •Lay the person on their side with one arm supporting the head. •The other arm should be in front with their elbow and forearm bearing a bit of upper body weight. •Follow the same pattern with the legs – lower leg straight, upper leg bent to bear some weight. •This position may prevent choking if the victim vomits. 3. How to administer rescue breathing ONE BREATH EVERY FOUR SECONDS A person has to breathe one breath every four seconds to keep their brain alive Count seconds between the overdose victim's breaths If there is more that 4 seconds between the person's breaths they will need you to breathe for them Check for a pulse, if no pulse, administer CPR If the heart is still beating but they are not breathing enough tilt the head back a bit, pinch the nose shut and give the person one regular-sized breath every four seconds Giving someone large breaths may cause air to go into the stomach and may end up in vomiting Keep giving rescue breathing until the person wakes up, or someone takes over for you, or the emergency personnel arrive Do not give up! If you cannot call 911, or you do not have naloxone, you may be able to keep the person alive by breathing for them as their body processes the opiates 3. How to administer rescue breathing ONE BREATH EVERY FOUR SECONDS 4. Administer the Antidote (naloxone) What is naloxone (Narcan)? Naloxone causes a rapid blockade of μ-opioid receptors stopping the opioid overdose and often producing rapid onset of withdrawal symptoms It is a synthetic drug, similar to morphine, that blocks opiate receptors acting as a opioid antagonist in the nervous system It was developed by Sankyo (global pharmaceutical company) in the 1960s Naloxone has an exceptionally high affinity for μopioid receptors in the brain and spinal cord making it a μ-opioid receptor competitive antagonist How to Administer naloxone (Narcan) 1. Naloxone can be administered as a nasal spray. 2. Remove the caps (red and yellow plastic corks) from the vial of naloxone and the syringe barrel. 3.Insert the vial into the barrel & turn the vial 3 times – slowly and gently – until it stops. 4. Screw the nasal atomizer onto the tip of the syringe. The naloxone is now ready to use. 5. Place the assembled naloxone atomizer in one of the overdose victim’s nostrils. 6. Press firmly on the base of the glass vial or plunger, spraying half of the naloxone deep into the overdose victim’s nasal cavity. 7. Spray the remainder into the other nostril. 8. If the person does not regain consciousness in a minute or two, administer a second dose. Where to Get naloxone (Narcan) Stanford Public Health Office (near UNM) 1111 Stanford Drive NE Albuquerque, NM 87106 (505) 841-4100 Casa de Salud/Just Healthcare 1608 Isleta Blvd. NW Albuquerque, NM 87501 (505) 907-8311 Conclusion There are few experiences in life that can cause such suffering as drug addiction. Until drug addicted people are ready to attempt sobriety, incarcerating them or allowing them to die lacks compassion and is poor public health policy. New Mexicans finally have tools to help keep our loved ones alive until they are ready to seek help. If you or someone you know use heroin or other opiates, avail yourself of naloxone.
