RESUMEN

INTRODUCTION: Bedside thoracic ultrasound has been shown to be a valuable diagnostic tool in the emergency department. The purpose of this study was to evaluate the feasibility of bedside thoracic ultrasound in the prehospital HEMS setting. SETTING: Air ambulance helicopters during patient transportation. METHODS: This was a prospective pilot study. 71 consecutive, nonpregnant patients over 18 years old were enrolled. While in flight, providers completed limited bedside thoracic ultrasounds with the patient supine and recorded their interpretation of the presence or absence of the ultrasonographic sliding lung sign on a closed data-set instrument. RESULTS: 41 (58%) of the eligible patients had a recorded thoracic ultrasound acquired in flight. The level of agreement in image interpretation between the flight crew and expert reviewer was substantial (Kappa 0.67, CI 0.44-0.90). The reviewer rated 54% of all images as "good" in quality. The most common reason cited for not completing the ultrasound was lack of enough provider time or space limitations within the aircraft cabin. CONCLUSION: The results of this study suggest that, with limited training, bedside thoracic ultrasound image acquisition and interpretation for the sliding lung sign in the HEMS setting is feasible.

RESUMEN

OBJECTIVE: To perform an initial screening study of methicillin-resistant Staphylococcus aureus (MRSA) contamination in an ambulance fleet. METHODS: This was a cross-sectional study of MRSA contamination in an ambulance fleet operating in the western United States in June 2006. Five specific areas within each of 21 ambulances (n = 105) were tested for MRSA contamination using dacron swabs moistened with a 0.85% sterile saline solution. These samples were then plated onto a screening media of mannitol salt agar containing 6.5% NaCl and 4 mcg/mL oxacillin. RESULTS: Thirteen samples isolated from 10 of the 21 ambulances (47.6%) in the sample group tested positive for MRSA. CONCLUSIONS: The results of this preliminary study suggest that ambulances operating in the emergency medical services (EMS) system may have a significant degree of MRSA contamination and may represent an important reservoir in the transmission of potentially serious infections to patients.
