About this study

Background: Cardiopulmonary resuscitation (CPR) during ambulance transport in Asia has been known to be ineffective for quality and unsafe for emergency medical services(EMS)providers. Small elevators in high rise buildings are the most serious barriers to provide high quality CPR due to too long stretcher cart to enter in the elevators. We developed flexible stretcher cart to be safely used in small elevator through reducing the length of the stretcher. This study aims to compare the quality of EMS CPR between flexible stretcher and standard stretcher during transport to hospital.

Method:

This is a before and after-trial in a metropolis EMS. Study targets are adult out-of-hospital cardiac arrest (OHCA), excluding evident death cases, pregnancy, DNR cases, and too big or too small body size for stretcher cart or mechanical CPR devices. In the before period, the standard stretcher will be used for manual CPR using standard CPR protocol. In the after period, the flexible stretcher will be used with mechanical CPR devices after 3 cycles of standard manual CPR. Individual and Utstein risk factors will be collected. Main outcomes are no-flow fraction (NFF) measured by defibrillators (X-series) and safety will be measured on mechanical error, transportation error, patient injury and EMS provider injury. Sample size were 24 cases for before (12 cases) and after (12 cases) trial from 80% power and 0.05 of alpha error for expecting 20% quality difference (30% NFF inflexible stretcher and 50% NFF in standard stretcher)

Expected impact:

The study will be expected to find the benefit of flexible stretcher cart during CPR in small elevators. This findings will contribute to revise the Asian EMS protocol for improving quality of CPR.

Treatment and study plan

Flexible EMS stretcher cart

Device

The flexible EMS stretcher cart is an innovative EMS stretcher cart built to be flexible to fit in smaller spaces such as elevators. The flexible stretcher bends at the hip joint as well as at the knee joint, so that the patient can be put in head-up position at 30 degrees elevation with elevated legs.

Primary outcomes

  1. Comparison of Percentage of Chest Compression Fraction Between Before- and After-phase Groups

    Time frame: During the total prehospital resuscitation time

    Chest compression fraction was calculated as proportion of CPR time spent providing compressions.

Secondary outcomes

  1. CPR Duration

    Time frame: During total prehospital resuscitation
