Objectives: This study was undertaken to evaluate difficult airway simulator intubation success rates using Commission on Accreditation of Medical Transport Systems (CAMTS) initial and maintenance intubation training standards on transport-RN novice intubators over a 1-year period.

Methods: Twelve transport nurses were blinded to and randomly assigned five or six of 64 different difficult airway simulator scenarios. Intubation success rates were measured 1 month before training, 1 month after training, and 1 year later, following CAMTS initial and maintenance intubation standards.

Purpose: This study evaluated the impact wearing a surgical facemask or N95 air purifying respirator (N95) has on radio reception.

Methods: We compared the ability of a flight crewmember and a layperson sitting in a Bell 407 crew compartment and a dispatcher sitting in a communication center to accurately record 20 randomized aviation terms transmitted over the radio by a helicopter emergency medical services (HEMS) pilot wearing a surgical facemask and six different N95s with and without the aircraft engine operating.

Results: With the aircraft engine off, all terms (100% accuracy) were correctly identified, regardless of the absence or presence of the surgical facemask or N95 studied.

Background: Although laparoscopic cholecystectomy was first introduced in Mongolia in 1994, the benefits of the laparoscopic approach have been largely unavailable to the majority of the population. The burden of gallbladder disease in Mongolia is significant. Despite the barriers to expanding laparoscopic surgery in Mongolia (lack of physical resources and adequate training opportunities, a difficult political situation, and an austere environment), the Health Sciences University of Mongolia (HSUM) began looking for ways to further the development of laparoscopy for the entire country, including the rural areas where half the population resides.

Purpose: in 2005, the Federal Aviation Administration recommended helicopter emergency medical systems implement a pre-flight risk assessment score (PRAS) to help pilots assess flight risks. To date, there are no studies evaluating the PRAS. This study examined the transport outcome (successful, aborted or turned-down) associated with our PRAS.

Purpose: To present our single-institution experience with image-guided radiotherapy comparing fiducial markers and cone-beam computed tomography (CBCT) for daily localization of prostate cancer.

Methods And Materials: From April 2007 to October 2008, 36 patients with prostate cancer received intensity-modulated radiotherapy with daily localization by use of implanted fiducials. Orthogonal kilovoltage (kV) portal imaging preceded all 1244 treatments.

Introduction: This study examined air medical transport (AMT) personnel's experiences with and opinions about prehospital and AMT research.

Methods: A Web-based questionnaire was sent to eight randomly selected AMT programs from each of six Association of Air Medical Services (AAMS) regions. Responders were defined by university association (UA) and AMT professional role.

Background: Portable blood gas analyzer and monitor devices are increasingly being used to direct ventilator therapy. The purpose of this study was to evaluate the "measure of treatment agreement" between portable and laboratory blood gas measurements used in guiding protocol-driven ventilator management.

Materials And Methods: Using National Institutes of Health Acute Respiratory Distress Syndrome network ventilator management guidelines to manage patient care, measurements taken from the Nonin 8500 M pulse oximeter (SpO2), the Novametrix-610 end-tidal CO2 (ETCO2) detector, and the i-STAT 1 (SaO2, PO2, pH, PCO2) were compared with the recommended treatment from paired laboratory ABL-725 (SaCO2, PO2, pH, PCO2) measurements.

Objectives: Mortality differences exist between victims of urban and rural trauma. It is unknown if these differences persist in those patients who survive to HEMS transport. This study examined the in-hospital mortality, hospital LOS, and discharge status of pediatric blunt trauma victims transported by HEMS from rural and urban scenes.

Objective: Mortality differences exist between victims of urban and rural trauma; however, it is unknown if these differences persist in those patients who survive to HEMS transport. This study examined the in-hospital mortality, length of hospital stay, and discharge status of adult blunt trauma victims transported by HEMS from rural and urban scenes to regional trauma centers.

Methods: Retrospective review of all adult (age >/= 15) HEMS transports in 2001; 271 urban and 141 rural blunt trauma patients were identified from HEMS transport records and the trauma registries at three level one trauma centers.

Purpose: To assess our single institutional experience with daily localization, using fiducials for prostate radiotherapy.

Methods And Materials: From January 2004 to September 2005, 33 patients were treated with 1,097 intensity-modulated radiation treatments, using three implanted fiducials. Daily portal images were obtained before treatments.

Background: Inadequate rest can result in disastrous medical and aviation errors. Using a prospective within-subjects design, this study compared the amount of daily sleep and the cognitive performance in flight nurses working 12-hour evening versus 18-hour shifts during a 72-hour duty schedule.

Methods: Ten flight nurses who worked two different duty schedules participated in the study.

Objective: To examine the characteristics of pediatric patients (age =16 years) injured at winter resort scenes and transported by helicopter emergency medical services (HEMS) or ground EMS (GEMS) ambulance services to regional trauma centers.

Methods: Between 1997 and 2001, a total of 119 patients (GEMS = 69; HEMS = 50) were identified from trauma registries and HEMS transport records. Demographic data, initial vital signs, hospital interventions, and discharge status of the two groups were examined.

Introduction: This study examined the epidemiology of winter resort injuries presenting to regional trauma centers by helicopter (HEMS) or ground (GEMS) ambulance.

Methods: Five hundred seventy-five patients (GEMS 289; HEMS 286) were identified from trauma registries and HEMS transport records. Demographic data, hospital interventions, and discharge status were examined.

Objective: To investigate prognostic significance of and correlations between HER1 (EGFR), HER2 (c-erb-B2), HER3 (c-erb-B3), HER4 (c-erb-B4), and phosphorylated Akt (P-Akt) in patients treated with radiation for cervical carcinoma.

Methods: Fifty-five patients with stages I-IVA cervical carcinoma were treated with definitive radiotherapy. Tumor expression of each biomarker was quantitatively scored by an automated immunohistochemical imaging system.

Objective: The aim of this study was to estimate the sensitivity, specificity, and positive predictive value (PPV) of computed tomography (CT) without oral contrast for diaphragm injuries (DIs) in blunt abdominal trauma.

Methods: We prospectively enrolled 500 consecutive "trauma-one" patients who received CT imaging and interpretation (CT-Read1) of the abdomen within 45 minutes of their arrival from July 2000 to December 2001. All patients were imaged without oral contrast but with intravenous contrast.

Objectives: To compare late rectal toxicity (LRT) after definitive radiotherapy (DR) and salvage radiotherapy (SR) in prostate cancer using conventional (CONV) or three-dimensional conformal (3-D) techniques.

Methods: The outcomes and clinical factors of 212 patients with Stage T1a-T4 prostate cancer were evaluated (separated into DR and SR groups). The median prescribed dose was 66, 74, 66, and 70 Gy, for the CONV-DR, 3-D-DR, CONV-SR, and 3-D-SR groups, respectively.

Background: Alterations in expression of adhesion molecules are important in the trafficking of hematopoietic progenitors and probably in the mobilization process. Relatively little and conflicting data are currently available on the differences in expression between good and poor mobilizing patients.

Study Design And Methods: In this study, the expression of eight adhesion molecules on the collected CD34+ cells from 36 patients undergoing mobilization was determined.
