More information can be found at the Critical Care Drug Manual - London Health Sciences Centre, UWO. The intensivist has the primary responsibility for the ICU patient’s care versus acting as a consultant, as many specialists do. Consider a "surgical" source of bleeding in the following situations: If any of the above criteria are noted you must notify the ICU Fellow or Attending and the Cardiac Surgery Fellow immediately. If it deflates too early in diastole its ability to afterload reduce will be limited. Theoretically, since it has inotropic activity as well, it is less likely to cause a decrease in cardiac output due to increased afterload compared to a pure alpha agonist such as phenylephrine. Or is it due to low SVR? By continuing to use this site you are giving us your consent. Cardiac Arrest After Cardiac Surgery: An Evidence-Based Resuscitation Protocol . Their approach is multi-factorial, led by CV surgeon Judson Williams, MD. Check the position of all other tubes and drains. cAMP is the "second messenger" that leads to increased calcium availability at the actin-myosin complexes and thus increased contractility. It should deflate just before left ventricular ejection. Verify correct position of the Swan-Ganz catheter. “Although it’s only 3 percent of the [cardiovascular] surgery population that arrest, once they do, survival to discharge is only 33 to 57 percent,” said Jessie Willard, UCHealth’s clinical director of Critical Care Services for northern Colorado. Patients are rewarmed using the "Bear Hugger". A variety of dysrhythmias also may occur during this period including bradycardias requiring pacing. Antifibrinolytic agents; Episilon-aminocaproic acid (AMICAR), tranexemic acid, or aprotinin. "Timing". Start at 0.5 to 1.0 mcg/min and increase by these amounts until adequate cardiac index. Both crystalloids (normal saline) and colloids (Pentaspan) can be given. Do a more complete neurologic exam when the patient begins to awaken from GA. ? A cardiac perfusionist is always on call to help with adjustment of balloon timing or any "trouble-shooting" that may be required. “It’s really neat to see this bedside buy-in. Look at the recent hemodynamic parameters. Topic Summary –1-2 page handout summary of the topic. Therapeutic components should include a pediatric cardiac catheterization laboratory equipped for interventional cardiology and transcatheter radiofrequency ablations, a cardiac operating suite suitable for surgical treatment of all pediatric cardiovascular patients, an extracorporeal membrane oxygenator (ECMO), and a cardiac intensive care unit (ICU) or pediatric ICU and/or neonatal ICU equipped and … Pre-operative defects secondary to hepatic disease. The Echocardiographer on call should be paged after discussion with the ICU Fellow or Attending. This involves cannulation of the right atrium and aorta (and later cross-clamping of the aorta), allowing the entire cardiac output to bypass the patient's heart and lungs. Predisposes to ventricular dysrhythmias and lowers VF threshold, Increases SVR; increases afterload and myocardial workload, Patient shivering causes increased peripheral O2 consumption, Decreases CO2 production; a patient who has a respiratory alkalosis (low PCO2) on initial ABG usually will increase their PCO2 with rewarming. ß2 effect can sometimes decrease SVR and BP. Kati Blocker has always been driven to learn and explore the world around her. The ng tube, chest tubes, and mediastinal sumps. Protocol for Cardiac Surgical Patients in the Intensive Care Unit The recommended modification of the AHA algorithm to be applied in cases of cardiac arrest after cardiac surgery is presented in Figure 1. Potassium, magnesium - a vigorous diuresis is common in the first few hours after the OR. Verify correct position of the ETT. This involves cannulation of the right atrium and aorta (and later cross-clamping of the aorta), allowing the entire cardiac output to bypass the patient's heart and lungs. PRBC; it is of utmost importance to maintain a hemoglobin level high enough to maintain adequate oxygen delivery during the period of significant bleeding. Quantitative platelet defects. Occasionally, the calculated dose of protamine given is not sufficient to completely reverse the heparin effect. In a patient who is bleeding significantly, the goal is to keep the platelet count greater than 100,000 of. It has specific protocols to intervene on the patient’s behalf earlier than ACLS would have you do.”. If it inflates too late, its ability to "augment" and effectiveness will be limited. Orally, metoprolol is used in the dose range of 25 to 200 … It’s the first set of guidelines from the nonprofit ERAS® Cardiac Society in collaboration with the ERAS® Society, an international initiative formed in the early 2000s to improve outcomes in many surgical areas. Distal pulses should be monitored at least hourly. The urine output typically decreases and other signs of end-organ hypoperfusion develop including CNS changes and acidosis. If the CVP increased by 3-4 but the cardiac output did not increase, then the patient is on the flat portion of the Starling curve and is not pre-load responsive. Titrate upward by 2.5 mcg/kg/min until adequate cardiac index. There are eight distinct strata or sub-populations within the SCIP Topic Population, each identified by a specific group of procedure codes. It’s a small number — 3%— of heart surgery patients who go into cardiac arrest in the days following their procedure. Listen for murmurs particularly if the patient has had valve surgery. Para español, haga clic aquí. Absolute or relative bradycardias or tachycardias (commonly new atrial fibrillation) can lead to decreased C.O. RESEARCH DESIGN AND METHODS A total of 120 consecutive patients after cardiac surgery were randomly assigned to the three protocols with a target glycemia range from 4.4 to 6.1 mmol/l. Use of Intra-aortic balloon pump (IABP), ventricular assist devices (VAD), or nitric oxide (NO). The arterial waveform usually works better if the patient is having arrhythmias. Protocols for “ Enhanced recovery after surgery (ERAS)” are on the rise in different surgical disciplines and represent one of the most important recent advancements in perioperative medical care. Qualitative platelet defects. “This will continue to protect our patients when problems are anticipated and should help to ensure our already excellent outcomes.”, Get the most popular stories delivered to your inbox monthly. No single bedside test or finding is sensitive or specific enough to absolutely rule in or out tamponade. Vaccines have arrived and we are implementing the distribution plan in coordination with the State. The following is an approach to managing the hypotensive patient; The following is a very simplified approach to the choice of inotropes and vasopressors. Introduction. It is sometimes difficult to liberate the patient from CPB or "get him off pump." Code Status 2. The main objective of this study was to explore the clinical impacts of administering midodrine in patients with … It is given post-cardiac surgery because it is felt it might improve platelet function although the data are mixed in this setting. Proper management of the hypotensive patient in the ICU requires that the precise etiology for the hypotension is determined and therapy is directed towards reversal of this specific problem. Ideally should confirm fibrinolysis before use ( elevated D-dimers, low fibrinogen). Clinical DIC is rare. Blood flow is maintained using a pump and the blood is oxygenated via a membrane oxygenator incorporated into the circuit. If you think the patient may be "preload responsive" (i.e., on the ascending portion of Starling's curve so that an increase in preload will increase cardiac output), then give the patient a fluid bolus. Look for a "loss of the y-descent" on the CVP or PCWP tracing. Pancreas transplant post-operative orders. Look at the cardiac rhythm. In cardiac surgery, only few ERAS protocols have been described in the past. We use cookies to make interactions with our website easy and meaningful. Notify ICU Fellow or Attending if > 5 mcg/min and each increase of 5 mcg/min above that. Data were collected 3 Should only be used after discussion with the ICU Attending. The goal is to facilitate learning of critical care medicine. Use of a clinical pathway (CP) may facilitate the care of these patients. The only treatment for cardiac tamponade is return to the OR, re-sternotomy, and evacuation of the clot with hemostasis of any ongoing bleeding. Author(s): Patrick Michaelis, BSN, RN, Richard J. Leone, MD, PhD. Notify ICU Fellow or Attending if at 10 mcg/kg/min or higher. However, with a patient who is not bleeding rapidly, one can take a more deliberate approach to transfusion. During this time, the patient must by systemically anticoagulated with heparin to an ACT >400 to prevent clotting in the bypass circuit. Traditional life support methods — which usually start with CPR — don’t make sense in an ICU where life-saving interventions are immediately available. Evidence-based ERAS protocols have been associated with reductions of up to 50% in complication rates and length of stay compared with conventional management in noncardiac surgical fields. This series includes "fellow life lessons" from current trainees in leadership with CHEST. The patients in eac… It can be triggered from the arterial waveform recorded from the catheter tip, or it can be timed to the QRS complex of the cardiac monitor. Obtain another set as soon as possible if they have not recently been done or if there has been a sudden change. Leg ischemia. This is written with a busy, fatigued resident in mind. Note that repositioning the patient (turning on their side) may also cause the drainage of a pre-existing collection of "old" darker blood that had pooled in the thorax. Low voltages on the ECG or an increase in the width of the superior mediastinum on serial chest X-rays are generally poorly sensitive or specific. Remember that there are several potential risks associated with the transfusion of red blood cells, including. Ideally, the choice of therapy should be guided by hematological laboratory tests including a CBC, PT, PTT, ACT, fibrinogen, and d-dimers. Heart transplant: Immunosuppressive protocol. The. 7 Introduction | UHS Cardiac ICU Handbook – Second edition 2016 dependency unit, the coronary care unit (both on D-level), and cardiothoracic theatres, cardiac pre and post-op wards and cardiac catheter laboratories (all on E level). Greater than 500 cc of bleeding in the first post-op hour. Although the CVP in normal individuals varies between 0 and 4 mmHg, patients immediately post-op cardiac surgery commonly have decreased cardiac compliance for multiple reasons. This blows warm air over the body surface to warm by convection. The differential diagnosis of low SVR includes; SIRS - a proportion of patients post CPB will have significant cytokine increases. An ACT will be done as soon as the patient arrives in the ICU. If it remains inflated during early systole it will impair LV ejection. Glucose - tight glycemic control post-operatively reduces morbidity. Beginning in 2017, WakeMed pioneered enhanced recovery protocols for CV surgery with impressive results. Nonetheless, the evolution of surgical perfusion techniques and anaesthetic management have allowed the successful implementation of fast-track care protocols after cardiac surgery. Most often, these dysrhythmias are transient and resolve. The Society for Enhanced Recovery After Cardiac Surgery (ERAS® Cardiac) mission is to optimize perioperative care of cardiac surgical patients through collaborative discovery, analysis, expert consensus, and dissemination of best practices. Several myocardial preservation techniques are used to protect the heart from ischemic damage during this period. Other significant co morbidity, with emphasis on those conditions that may alter the post-operative management or course (carotid artery disease, COPD, asthma, diabetes, renal failure, hepatic failure, etc.). The resident should be present in the ICU when the patient arrives from the operating room to receive a sign-over from the anesthesiologist and the cardiac surgical team. Lipids Here is a checklist that should be followed for every ICU patient: Daily Checklist Every day each person should have the following addressed: 1. Rationale, aims and objectives: Cardiac surgery (CS) is facilitated by multiple perioperative guidelines and protocols. Clotting factor deficits. Inhibit conversion of plasminogen to plasmin thus preventing activation of fibrinolysis. UCHealth recently initiated the Cardiac Surgery Advanced Life Support (CALS) protocol in its cardiovascular intensive care unit at MCR. July 10, 2017. The half life of milrinone is several hours, unlike the catecholamines that have half-lives of a few minutes. Many patients are on anti-platelet agents pre-operatively. The ICU Fellow or Attending should be notified about any significant bleeding whether it is believed to be "medical" or "surgical.". The principle objective when giving PRBC's is the improvement of inadequate oxygen delivery and the minimization of adverse outcomes as a result of this. The most common complication. In the post-op cardiac surgery patient, it is possible to have a small, well-localized clot that impedes filling to only one chamber and thus cause unequal pressure changes.. For example, a right sided clot may raise only the CVP and impair filling to only the right atrium or ventricle. Familiarisation with Equipment There is a large array of equipment used on the cardiac intensive care unit. “Sometimes patients and their hearts/cardiovascular systems are irritable and labile. For more information and answers to commonly asked questions, visit our COVID-19 vaccine page. Cardiac tamponade is compression of the heart that impairs ventricular filling and leads to a low cardiac output. Most post-operative cardiac patients, who are hemodynamically stable, are not actively bleeding, and are following an otherwise uncomplicated post-operative course, tolerate a Hgb as low as 7.0 g/dL without problems. Residual heparin effect; patients are anticoagulated before going on CPB with a large dose of heparin to maintain their ACT >400. While it can increase urine output by several mechanisms, there is little evidence that it improves creatinine clearance or decreases the incidence of acute renal failure. Verify pacemaker settings if the patient is connected to one. The IABP consists of a long cylindrical balloon placed at the end of a catheter placed in the descending thoracic aorta. Is this tamponade? ß1 effect can cause dysrhythmias. While "on pump", the patient's BP and cardiac output are controlled by by the perfusionist and also the anesthesiologist by means of vasoactive medications and inotropes. Cardiac markers - elevations of CPK, CPK-MB, and troponins are non-specific. HTN 5. Pressors or inotropes are often used in order to aid "coming off pump." The tip should not be too peripheral - no more than 1 to 2 fingerbreadths beyond the lateral mediastinal shadow. Assure that the endotracheal tube is in proper position and the patient has equal air entry bilaterally. Ease of separation from CPB ( dysrhythmias, need for inotropes, pacing, etc). This is the best test to assess for tamponade. And every day, as a writer for UCHealth, Kati meets inspiring people, learns about life-saving technology, and gets to know the amazing people who are saving lives each day. This post is a part of our Life as a Fellow blog post series. Check the patient's heart rhythm. This can lead to significant hypokalemia and hypomagnesaemia which increases the likelihood of post-operative dysrhythmias. Postoperative neurological dysfunction following cardiac surgery can be a devastating outcome for the patient and their family. Both nurses attended a CALS conference in 2014, and instructor training in 2015, becoming two of the first health care professionals in the United States certified to train others in CALS. Check the ABG results as soon as they are available. In an effort to reduce the spread of COVID-19 and to keep our patients and staff safe, visitors are allowed under limited conditions. Rapid Extubation Following Cardiac Surgery With a Nurse Driven Protocol Previous Article Extubation Criteria for Patients With Total Artificial Heart (TAH) Next Article To Determine the Predictors of Mortality and Morbidity of Sepsis in Medical ICU of All India Institute of Medical Sciences (AIIMS), New Delhi, India This is followed by hemodynamic deterioration with tachycardia, declining cardiac output and stroke volume, and decreasing mixed venous oxygen. Cardiac Surgical Critical Care Medicine: The Role Critical Care Physicians Can Play in Improving Outcomes After Cardiac Surgery By: Bravein Amalakuhan, MD. A valve repair or replacement can rarely have acute dehiscence. Dopamine - stimulates dopaminergic, beta, and alpha receptors in dose-dependent fashion. Now at Medical Center of the Rockies, new cardiac arrest protocols for cardiac surgery patients has been initiated to help that 3% pull through. The absence of respiratory variation on the CVP monitor tracing is also suggestive that the patient has an adequate preload and that further volume therapy is unlikely to increase cardiac output. By inflating at the beginning of diastole (just after the closure of the aortic valve), the aortic diastolic pressure is increased or "augmented", thus improving coronary perfusion. Practically speaking, one does not always have the luxury of time with patients bleeding significantly and one may have to resort to empiric or "shotgun" therapy. A multidisciplinary extubation protocol was created. Preliminary CALS outcomes are showing that the new protocol — and the early interventions it promotes — are keeping patients from arresting because it allows staff to pace (using a pacemaker) the patient before they go into full arrest, whereas ACLS would have them doing chest compressions. Prolonged CPB time or cross-clamp times, difficulty with myocardial protection intra-op, Acute bypass graft occlusion (check the ECG), Graft spasm (especially LIMA) - check the ECG for ST elevation. CAD 2. Check pupillary reflexes. “We’ve had several patients since initiating this protocol where we’ve done this and got their rhythm back and prevented them from going into a full arrest,” Willard said. Cardioplegic arrest is induced using a hyperkalemic solution to induce asystole and thus decrease myocardial metabolism and oxygen consumption. This can lead to a rapid deterioration in the patient’s condition that requires a quick recognition and intervention. "Diastolic decrement" .The balloon deflates just before cardiac systole (just before opening of the aortic valve). Causes vasoconstriction and thus increases SVR and BP. Patients may also receive additional heparin if they are given back blood that remained in the bypass circuit when the patient was disconnected from CPB ("pump blood"). In the failing heart it can decrease myocardial workload while increasing coronary perfusion. Persistent hypotension is a frequent complication after cardiac surgery with cardiopulmonary bypass (CPB). This has been shown to improve platelet function and decrease active bleeding in uremia or vonWillebrand's disease. Check the initial hemodynamic readings (HR, BP, cardiac output and index, CVP, PCWP) and determine what vasoactive infusions the patient is on and at what rates.
