New cardiopulmonary resuscitation guidelines 2005: importance of uninterrupted chest compression

Impact of structured basic life-support course on nurses' cardiopulmonary resuscitation knowledge and skills: Experience of a paediatric department in low-resource country

INTRODUCTION

The study aimed to assess the impact of a modified paediatric basic life support (BLS) training on paediatric nurses' knowledge and skills in the main tertiary level public hospital in Rwanda.

METHODS

A prospective, before-and-after educational intervention study was performed. Nurses working in the paediatric department at Centre Hospitalier Universitaire de Kigali (CHUK) were enrolled after consenting to the study. A modified BLS training was administered using didactic lectures, videos, case discussions, and simulations. Knowledge and skills were assessed before, immediately and six months after the training, using the American Heart Association (AHA) multiple-choice questions test and simulation scenarios. Ethical approval from the hospital's investigational review board was obtained before the start of the study.

RESULTS

Fifty-seven nurses working in paediatric department were included in the study, most with advanced nursing degrees. At baseline, only 3.5% scored above 80% on the knowledge test and none were able to perform high-quality one-rescuer CPR. Knowledge and high-quality one-rescuer CPR skills improved significantly immediately after the training, with 63.2% scoring above 80% and 63.2% capable of performing high-quality one-rescuer CPR (p < 0.01). Six months later, only 45.6% scored above 80% and 15.8% were capable of performing high-quality one-rescuer CPR (p < 0.01). Some skills, such as delivering breaths using bag-mask device, showed better retention.

CONCLUSION

In the paediatric department of the main public tertiary care hospital in Rwanda, nurses' baseline knowledge and skills in providing BLS was poor but can increase with focused BLS training. Due to the decline in knowledge and skills over six months, the use of debriefing and focused trainings following resuscitation events and improved implementation of yearly departmental refresher courses are recommended.

Extracorporeal Life Support After Prolonged Resuscitation for In-Hospital Cardiac Arrest due to Refractory Ventricular Fibrillation: Two Cases Resulting in a Full Recovery

Extracorporeal life support (ECLS) has well demonstrated its efficacy in treating in-hospital cardiac arrest and is being used for broader indications. However, ECLS after prolonged cardiopulmonary resuscitation (CPR) has been traditionally contraindicated and is now challenging. Here, we introduce two cases of successful ECLS after prolonged CPR, resulting in a immediate and full recovery. Both these acute ST elevation myocardial infarction patients waiting for primary percutaneous coronary intervention (PCI) suddenly collapsed due to ventricular fibrillation (VF), which was refractory to conventional treatment. After 2 hours of conventional CPR, the ECLS had been implemented and primary PCI could be performed. Subsequent to successful revascularization, the VF was stopped with a single electric shock. In our second case, normal sinus rhythm was spontaneously restored after ECLS implementation, which was completed after 45 minutes of conventional resuscitation. Both patients made a full neurological recovery on the day of the event and were discharged with only minor complications.

Cardiopulmonary resuscitation: from the beginning to the present day

Cardiac arrest represents a dramatic event that can occur suddenly and often without premonitory signs, characterized by sudden loss of consciousness and breathing after cardiac output ceases and both coronary and cerebral blood flows stop. Restarting of the blood flow by cardiopulmonary resuscitation potentially re-establishes some cardiac output and organ blood flows. This article summarizes the major events that encompass the history of cardiopulmonary resuscitation, beginning with ancient history and evolving into the current American Heart Association's commitment to save hearts.

Using simulation to orient code blue teams to a new hospital facility

OBJECTIVES

Prompt and successful cardiopulmonary resuscitation during a sudden cardiac arrest can be hindered by multiple variables, ie, ineffective communication, stress, lack of training, and an unfamiliar environment, such as a new hospital facility. The main objective of the study was to use high-fidelity simulations to orient Code Blue Teams (CBTs) to critical events in a new hospital facility. A secondary objective was to elucidate factors that may have contributed to responses by debriefing teams.

METHODS

Mock Code Blue exercises using high-fidelity simulation were implemented in real workplace settings to orient CBTs to critical events. We measured arrival time of first responder, crash cart to code site, first six CBT responders, first chest compression, and first electrical shock. After each mock code, participants were debriefed to assess any barriers to effective response and decision making.

RESULTS

Twelve mock codes were conducted at different locations of the new facility. Sixty-nine percent of the participants reported that the training was beneficial. The median time of arrival of the first responders was 42 seconds and the first CBT member was 66 seconds. The median time to initiation of chest compressions was 80 seconds, crash cart arrival was 68 seconds, and first electrical shock was 341 seconds. An additional outcome of the study was the identification of facility and systems issues that had the potential to impact patient safety.

CONCLUSIONS

Clinical simulation can be effectively used to orient CBTs and identify critical safety issues in a newly constructed healthcare facility.

Utstein style study of cardiopulmonary bypass after cardiac arrest

OBJECTIVE

The aim of this study is to describe the effect emergency cardiopulmonary bypass (CPB) for resuscitation on the survival rate of patients.

METHODS

The study population was composed of persons 16 years or older who had out-of-hospital cardiac arrest and were transferred to the Sapporo Medical University Hospital from the scene between January 1, 2000, and September 30, 2004. Children younger than 16 years and persons who were dead were excluded. Data were collected according to the Utstein style. Survival rates and cerebral performance category were analyzed using chi(2) analysis for the patients with presumed cardiac etiology. Cardiopulmonary bypass was applied to patients who showed no response with standard advanced cardiac life support. The interval from collapse and other noncardiac etiologies were considered criteria for exclusion.

RESULTS

Of the 919 patient medical records reviewed, CPB was performed in 92 patients. Of the 919 patients, 398 were of presumed cardiac etiology (n = 66 for CPB), 48 patients survived, and 24 patients (n = 7 for CPB) had a good cerebral outcome (cerebral performance category score 1). With CPB, the rate of survival at 3 months increased significantly (22.7% vs 9.9%, P < .05), but the rate of good cerebral outcome (10.6% vs 5.1%, P = .087) showed a positive trend.

CONCLUSION

The use of CPB for arrest patients was associated with reduced mortality. It did not increase good neurologic outcome significantly. Still, 7 cases with intact central nervous system would have been lost without CPB.
