  • Now that the PCP scope includes utilizing an SGA in patients outside of cardiac arrest, can salbutamol be administered via SGA utilizing the airway adaptor? This would be the same piece of equipment allowing MDI of Salbutamol for BVM, CPAP, CPAP, ETT and SGA.

  • In regards to Dex administration being contraindicated for patients currently on parenteral or PO steroids, can we get some more clarification on what we are referring to specifically – is it basically all steroids? Most patients with COPD tend to be on steroid puffers which presumably would make those patients not able to receive dexamethasone?

  • In regards to medications with a condition of “unaltered”, should we be administering these if the pt is GCS 15, then has a syncopal episode (or other altered period) in your care and then returns to GCS 15? An example would be a chest pain call where you want to treat with ASA and Ondansetron. Is it a case of “once you’re out you’re out” or would it still be appropriate to treat as they have now returned to an unaltered state? Thanks

  • In regards to the analgesia directive, should we withhold pain medication in the event that the mechanism of injury is severe even if the patient has no obvious signs of a head injury or a bleed? For example: a car accident at very high speeds where pt is only complaining of severe back pain, no LOC or confusion, would it be appropriate to give either Advil/Tylenol or toradol since there are no obvious contraindications or would it be better to withhold since the mechanism of injury is serious enough that they would still be possibilities?

  • I have a question regarding the PCP analgesia medical directive. If a patient has been using topical gels for pain relief (such as voltaren gel containing diclofenac), is ibuprofen/ketorolac still contraindicated if it has been used within the last 6 hours?

  • In the latest version of the companion document (v5.1) the following is stated “For a witnessed arrest in the back of the ambulance paramedics should use clinical judgment to decide whether to stay and perform resuscitation or proceed to hospital. Paramedic should perform three full analysis and then proceed/patch or to provide one analysis and go. The paramedic should provide at minimum one analysis. Factors that are part of the decision process include distance to closest hospital, probable cause of arrest, ability to provide adequate CPR/ventilation, shockable vs non-shockable etc..”. I was told during my recert in November that this scenario would warrant a 20 minute resuscitation. Can you please clarify.

  • If My patient goes VSA in the back of the truck (witnessed, first time VSA). We do not do 20 min CPR? Or we do 3 analysis and go after? And/or 1 analysis and go? Does the same apply witness VSA in the home? Do these require patch to leave early? There has been excessive talk over this and little clarification.

  • Refractory V-fib for the new medical cardiac VSA directive. Are we to only get our three shocks and go. Or can we give an additional shock if time permits due to extrication or extenuating circumstances? Just looking for clarification.

  • If we pick up a patient and the patient presents with a positive 12-lead STEMI and you are travelling to the PCI Center and the patient codes, do we run the full 20 minute cardiac arrest protocol, or could you consider STEMI as a reversible cause (Hs and Ts) , analyze once and head to the closest receiving which may not be the PCI due to distance.

  • Hello, with the changes to PCP medical cardiac arrest, since there is no longer a maximum number of analysis are we expected to continue to analysis the rhythm every two minutes on route to hospital if were transporting?. Seems like it would delay our arrival time a fair bit to pull over every two minutes especially in the county. Also, if a confirmed STEMI codes on route, should we be running a full 20 minute resuscitation before continuing transport, or would that be considered a reversible cause to transport after one analysis?. Thanks

  • The new Medical Cardiac Arrest Directive requires 20 minutes of resuscitation on scene. Point # 5 of the Primary Clinical Consideration(s) states …or other known reversible cause of arrest not addressed. My question has to do with refractory PEA and the amount of potential reversible causes (7 Hs 5 Ts). Would it be reasonable to patch for request of early transport in the presence of 3 consecutive analysis of PEA?

  • There has been a lot of debate in regard to the new medical cardiac arrest directive, especially when it comes to pediatric patients (1 day to less than 8 years old). Based on my understanding of the new directive, patients 24 hours old now fall under medical cardiac arrest which states that scene time is now 20 minutes unless you have a reversible cause or 3 consecutive shocks, since TOR would not apply here. Some paramedics express significant discomfort staying on scene for that long if the patient has been stabilized with good airway, quality compressions, and possibly defibrillation. Do you support paramedics leaving early in this setting where everything is done early or do you encourage us to stay on scene for 20 minutes? Does this benefit the patient when they could be receiving life saving drugs in a hospital, also knowing that we will eventually have to transport to a hospital no matter what?

  • Can you please clarify the CPR ratio for different ages with the new neonatal resuscitation changed from 30 days to 24 hours. At what age are we performing 3:1 CPR, 15:2. and 30:2?

  • Question: Can a paramedic in the field rule out ischemic chest pain and not treat with ASA/Nitro due to the chest pain being reproducible? (eg. worse on deep inspiration but radiating down the left arm/shoulder, and sharp pain in left upper chest and pressure across the lower chest). I recently had this call, and was told that you can rule it out based on it being reproducible, but the history and rhythm strip, clinical presentation was leaning more towards cardiac.

  • Hello, what are the criteria for identifying hypothermia in a VSA patient? This affects our treatment under ALS PCS 5.1 whether we consider early transport after one analysis. The situation that brought up this discussion was a patient who had been on the floor indoors for a number of days, but still presented with a hypothermic body temperature. If the patient had been found VSA, how would we identify to treat them under the full medical cardiac arrest, or be considered for early transport?

  • In regards to the cardiac ischemia medical directive, the latest indication is now suspected cardiac ischemia. If you have a pt presenting with all signs and symptoms of cardiac ischemia, have given ASA, established an IV, and have given NTG. If the pt’s symptoms improve after administration of NTG should you continue with the directive to the full amount of doses provided the pt still meets the conditions?

  • What is the SWORBHP stance on administering salbutamol in patients with suspected ACPE? Most of us have been traditionally taught that salbutamol in patients presenting with crackles due to suspected ACPE is a negative thing because of the bronchodilation and the risk of flooding a patient. However, there are many studies that argue salbutamol administration could be beneficial. Especially in situations where patients are presenting with both wheezes and crackles, it can get confusing. Where does SWORBHP stand on this topic?

  • For acetaminophen and ibuprofen, suspected ischemic chest pain is listed as a contraindication. Is this listed mainly to indicate that ischemic chest pain should not be treated with the analgesia directive? Could analgesics be administered to treat a different area of pain that is occurring at the same time as the chest pain that appears to be unrelated? For example, I had a patient with chronic pain that she takes acetaminophen for, but she was experiencing acute chest pain suspected to be ischemic. Would it be correct to withhold acetaminophen in this case and not provide treatment for the chronic pain that she is experiencing at the same time as suspected cardiac ischemia?

  • My question is in regards to when an IV certified medic is working with a non-certified medic. If the certified medic establishes IV access and has a lock in place, but doesnt give any fluids or medications can the non-certified medic still continue to attend the call? Or does the certified one become the attending. Specific example would be a Code Stroke where we established IV access prior to leaving scene, but it was originally the non-certified medics call.

  • I have a question in regards to the hypoglycemia directive. We were dispatched to a patient who suffered a fall, with history of diabetes. Upon assessment the patient was GCS 15, answering questions appropriately and oriented to person, place, time and event, however the patient was unable to move their limbs, and had loss of sensation in portions of the arms, torso, and legs, as well as a depressed skull fracture. The patient was hypovolemic and hypoglycemic at 3.2, stating he has not been eating or drinking fluids all day. Due to a complaint of back pain and paralysis, the a c-dollar was applied and scoop was used to extricate. Because the patient was secured to the stretcher supine, treating with oral gel was not an option, and transport was a priority. Some of the symptoms exhibited by the patient are concurrent with typical signs of hypoglycemia. In this situation where the patient is NOT altered, but hypoglycemic, with sufficient suspicion to suspect that low blood sugar may be causing some of the symptoms, would it be reasonable to treat the patient with IV dextrose? How do we proceed in situations where patients may be hypoglycemic, are not altered (GCS less than 15) but are unable to tolerate oral glucose or carbs? I can see this being the case for traumas.

  • So we had a call to a burn victim that was grossly charred, but was breathing. He started to deteriorate in transport but we made it to the hospital. I was wondering if he were to arrest if that would be a traumatic VSA, I know it’s not a blunt or penetrating trauma but it doesn’t make much sense as a medical cardiac arrest either. Also could a patient meet the standards for an obvious death after patient contact?
