Survival of Cardiorespiratory Arrest After Coronary Artery Bypass Grafting or Aortic Valve Surgery

Implementing Cardiac Surgical Unit-Advanced Life Support Through Simulation-Based Learning: A Quality Improvement Project

BACKGROUND

The European Association for Cardio Thoracic Surgery and the Society of Thoracic Surgeons endorse Cardiac Surgical Unit-Advanced Life Support, a protocol designed specifically for cardiothoracic surgical patients who suffer postoperative cardiac arrests. To enhance patient outcomes and to reduce death rates, cardiothoracic intensive care unit nurses must be able to perform the protocol with confidence, proficiency, and without delays. To this end, simulation-based learning (SBL) is a pedagogical method ideal for optimized learning.

OBJECTIVES

This quality improvement project was designed to implement a post-cardiac surgery resuscitation protocol in a nonacademic, community medical center to enhance nurse knowledge, confidence, and proficiency for optimal patient outcomes.

METHODS

The Cardiac Surgical Unit-Advanced Life Support is an evidence-based resuscitation protocol that was implemented using didactic, hands-on training, and SBL. It was evaluated using knowledge surveys, comparisons in nurse confidence and performance measures, and patient outcomes data.

RESULTS

Nurses' knowledge gains (ie, mean test scores) on our test were statistically significant between 3 time points (F2,60 = 81.204, P < .001). Knowledge significantly increased from pre-education to immediate post-education (P < .001), but declined from immediate post-education to 3-month post-education assessments (P < .001); however, the 3-month post knowledge mean was still higher than the pre-education knowledge mean (P < .001). Nurses were confident in their ability to apply the protocol, although results failed to show a correlation between confidence and performance ability. Statistical significance for delay in cardiopulmonary resuscitation was found between pre- and post-nursing education patient cardiac arrest events (P = .05).

CONCLUSIONS

Didactic and hands-on learning supported knowledge retention over time for cardiothoracic surgical intensive care unit nurses. Improving self-confidence and the application of an unfamiliar resuscitation protocol through SBL and any impact a training program has on patient outcomes will require ongoing practice and more evaluation.

Cardiopulmonary arrest after cardiac surgery: A retrospective cohort of 142 patients with nine year follow up

BACKGROUND

Although the techniques and perioperative management in modern cardiac surgeries has improved, and mortality and morbidity have decreased dramatically, postoperative cardiac arrest after heart surgery (POCHS) is a life-threatening condition that should be assessed and managed precisely.

OBJECTIVE

To determine the mortality rate and causes of death in postoperative cardiac arrest after heart surgery (POCHS).

METHODS

A total of 3342 patients underwent cardiac surgery from 2010 to 2018 in Isfahan, Iran .142 of them experienced POCHS . POCHS patients were investigated for characteristics, causes of cardiopulmonary arrest, first-line treatment, and mortality. These items were compared between survived and deceased patients to find possible prognostic factors.

RESULTS

The incidence rate of cardiac arrest was 4.2% (142 ones from total of 3342). Success rate of cardiac arrest is 28.8% (41 from 142). Bradycardia was the most common cause of cardiorespiratory arrest (37.3%), followed by cardiogenic shock (30.3%) and ventricular fibrillation (23.2%). Younger patients (58±11.5 versus 62.9±11.3) and those who developed cardiopulmonary arrest due to ventricular fibrillation (42.4% versus 22.2%), bradycardia (21.2% versus 8.8%), and apnea (15.1% versus 6.6%) were more likely to survive, while, those with shock had the worst prognosis (P<0.05). The best response to resuscitation was found among those treated with defibrillator plus ECM (External Cardiac Massage) as compared to the other approaches (P-value=0.003).

CONCLUSION

Based on the current report, CPR success was found in 28.6% among whom respiratory etiology led to better outcomes than cardiac etiology. The second cause of cardiac arrest is ventricular fibrillation which immediate defibrillation has the best outcome. The highest numerical success in POCHS is combination of ECM with defibrillator.

Implementation of an Innovative Nurse-Driven Resuscitation Protocol

Creating nurse-driven protocols empower nurses to practice at the top of their scope and provide early interventions. This article describes the development and implementation of an evidence-based, nurse-driven resuscitation protocol for cardiac surgical patients who suffer cardiac arrest using a theoretical framework and leadership-driven process. Readers will gain knowledge of the collaborative process required to develop and implement a complex practice change. Process measures, outcomes, and lessons learned are presented.

Cardiac Arrest After Cardiac Surgery: An Evidence-Based Resuscitation Protocol

More than 250 000 cardiac surgical procedures are performed annually in the United States. Postoperative cardiac arrest rates range from 0.7% to 5.2%. This article reviews current evidence for cardiac arrest resuscitation after cardiac surgery. The evaluation included resuscitation guidelines and 22 studies identified through a MEDLINE search. Evidence-based resuscitation differs from advanced cardiovascular life support guidelines. European Resuscitation Council guidelines include correcting reversible causes of arrest, applying defibrillation/pacing before external cardiopulmonary resuscitation, resternotomy within 5 minutes if electrical therapies fail, and restricting epinephrine use to avoid rebound hypertension. A 2017 Society of Thoracic Surgeons protocol derived from European Resuscitation Council guidelines is now standard of care in the United States. Evidence-based practices can improve survival and reduce resternotomy rates. This article describes the clinical implementation of the Society of Thoracic Surgeons guidelines.
