Studies of ambulance patients with ischemic heart disease. 11. Selection of patients for ambulance telemetry.

One hundred eighty-two of 1,928 patients (9.4 per cent) transported by ambulance during a six-month period in Baltimore had ECGs transmitted. Review of the remaining 1,746 records by two cardiologists indicated that an additional 113 patients should have had their ECGs transmitted because of life-threatening conditions. Of patients with acute ischemic heart disease, 47 had ECG monitoring and 24 did not. There were 22 per cent more Killip 111/1V patients with a 19 per cent higher mortality at three months among the "non-transmitted" patients as compared to the "transmitted" patients, controlling for all other relevant variables. Critical presentations inappropriately affect ambulance staffs' selection of patients for monitoring.

Evaluation of a training program for persons with SCI paraplegia using the Parastep 1 ambulation system: part 1. Ambulation performance and anthropometric measures.

OBJECTIVE: To describe performance parameters and effects on anthropometric measures in spinal cord injured subjects training with the Parastep 1 system. DESIGN: Before-after trial. SETTING: Human spinal cord injury applied research laboratory. PARTICIPANTS: Thirteen men and 3 women with thoracic (T4-T11) motor-complete spinal cord injury: mean age, 28.8yrs; mean duration postinjury, 3.8yrs. INTERVENTION: Thirty-two functional neuromuscular stimulation ambulation training sessions using a commercially available system (Parastep-1). The hybrid system consists of a microprocessor-controlled stimulator and a modified walking frame with finger-operated switches that permit the user to control the stimulation parameters and activate the stepping. OUTCOME MEASURES: Distance walked, time spent standing and walking, pace, circumferential (shoulders, chest, abdomen, waist, hips, upper arm, thigh, and calf) and skinfold (chest, triceps, axilla, subscapular, supraillium, abdomen, and thigh) measurements, body weight, thigh cross-sectional area, and calculated lean tissue. RESULTS: Statistically significant changes in distance, time standing and walking, and pace were found. Increases in thigh and calf girth, thigh cross-sectional area, and calculated lean tissue, as well as a decrease in thigh skinfold measure, were all statistically significant. CONCLUSIONS: The Parastep 1 system enables persons with thoracic-level spinal cord injuries to stand and ambulate short distances but with a high degree of performance variability across individuals. The factors that influence this variability have not been completely identified.

Assisted ambulation and activities for persons with profound multiple disabilities: assessing different ambulation levels.

Two participants with profound multiple disabilities were exposed to two occupational situations, which included 1-min. and 3-min. robot-assisted ambulation prior to each activity, respectively. Analysis showed participants' mean percentages of engagement time (session time they spent ambulating or manipulating objects) were well above 90 in both situations. The amount of deviant behavior was somewhat higher in the latter occupational situation for one participant. Implications of the findings were discussed.

Patients' experiences of care provided by emergency care practitioners and traditional ambulance practitioners: a survey from the London Ambulance Service.

Patients' experiences after receiving care from emergency care practitioners (ECPs) were compared with those after receiving care from traditional ambulance practitioners using a postal questionnaire distributed to 1658 patients in London; 888 responses were received. The responses of patients receiving care from both groups were similar and largely positive. But in two areas ("thoroughness of assessment" and "explaining what would happen next"), the care provided by ECPs was experienced as considerably better. These differences were partly explained by considerably fewer patients from ECPs being conveyed to the emergency department, suggesting that empowering ECPs to explore and explain alternatives to the emergency department improves patient satisfaction.

The controversy surrounding sacral insufficiency fractures: to ambulate or not to ambulate?

Sacral insufficiency fractures are an often unsuspected cause of low back pain in elderly women with osteoporosis who have sustained minimal or no trauma. Many of the references in the literature advocate bed rest initially; however, we support early mobilization, because most of these fractures are stable and require no surgical intervention. With good pain control, patients can begin progressive ambulation with assistive devices in a supervised environment and minimize the complications of immobility.

Decompression sickness during simulated extravehicular activity: ambulation vs. non-ambulation.

BACKGROUND: Extravehicular activity (EVA) is required from the International Space Station on a regular basis. Because of the weightless environment during EVA, physical activity is performed using mostly upper-body movements since the lower body is anchored for stability. The adynamic model (restricted lower-body activity; non-ambulation) was designed to simulate this environment during earthbound studies of decompression sickness (DCS) risk. DCS symptoms during ambulatory (walking) and non-ambulatory high altitude exposure activity were compared. The objective was to determine if symptom incidences during ambulatory and non-ambulatory exposures are comparable and provide analogous estimates of risk under otherwise identical conditions. METHODS: A retrospective analysis was accomplished on DCS symptoms from 2010 ambulatory and 330 non-ambulatory exposures. RESULTS: There was no significant difference between the overall incidence of DCS or joint-pain DCS in the ambulatory (49% and 40%) vs. the non-ambulatory exposures (53% and 36%; p > 0.1). DCS involving joint pain only in the lower body was higher during ambulatory exposures (28%) than non-ambulatory exposures (18%; p < 0.01). Non-ambulatory exposures terminated more frequently with non-joint-pain DCS (17%) or upper-body-only joint pain (18%) as compared with ambulatory exposures, 9% and 11% (p < 0.01), respectively. DISCUSSION: These findings show that lower-body, weight-bearing activity shifts the incidence of joint-pain DCS from the upper body to the lower body without altering the total incidence of DCS or joint-pain DCS. CONCLUSIONS: Use of data from previous and future subject exposures involving ambulatory activity while decompressed appears to be a valid analogue of non-ambulatory activity in determining DCS risk during simulated EVA studies.
