ABSTRACT
OBJECTIVES: Auricular acupressure is known to decrease the level of anxiety in patients during ambulance transport. The purpose of this randomized, double-blind, sham control study was to determine whether auricular acupressure can decrease not only the level of anxiety but also the level of pain in a group of elder patients with acute hip fracture. METHODS: With the assistance of the Vienna Red Cross, 38 patients with acute hip fracture were enrolled into this study. Patients were randomized into two study groups: the true intervention group and the sham control group. Subjects in the true intervention group (n = 18) received bilateral auricular acupressure at three auricular acupressure points for hip pain. Patients in the sham group (n = 20) received bilateral auricular acupressure at sham points. Baseline demographic information, anxiety level, pain level, blood pressure, and heart rate were obtained before the administration of the appropriate acupressure intervention. The level of anxiety, level of pain, hemodynamic profiles, and level of satisfaction were reassessed once the patients arrived at the hospital. RESULTS: Patients in the true intervention groups had less pain (F = 28, p = 0.0001) and anxiety (F = 4.3, p = 0.018) and lower heart rate (F = 18, p = 0.0001) on arrival at the hospital than did patients in the sham control group. As a result, the patients in the true intervention group reported higher satisfaction in the care they received during the ride to the hospital. CONCLUSIONS: The authors encourage physicians, health care providers, and emergency rescuers to learn this easy, noninvasive, and inexpensive technique for its effects in decreasing anxiety and pain during emergency transportation.

BACKGROUND: Patients with acute low back pain may require emergency transport because of pain and immobilization. Transcutaneous electrical nerve stimulation (TENS) is a nonpharmaceutical therapy for patients with low back pain. OBJECTIVE: To evaluate the efficacy of paramedic-administered TENS in patients with acute low back pain during emergency transport. METHODS: This was a prospective, randomized study involving 74 patients transported to hospital. The patients were randomly assigned to two groups: group 1 (n = 36) was treated with true TENS, while group 2 (n = 36) was treated with sham TENS. The authors recorded pain and anxiety as the main outcome variables using a visual analog scale (VAS). RESULTS: The authors recorded a significant (p < 0.01) pain reduction (mean +/- standard deviation) during transport in group 1 (79.2 +/- 6.5 mm VAS to 48.9 +/- 8.2 mm VAS), whereas pain scores remained unchanged in group 2 (75.9 +/- 16.4 mm VAS and 77.1 +/- 11.2 mm VAS). Similarly, the scores for anxiety were significantly reduced (p < 0.01) in group 1 (81.7 +/- 7.9 mm VAS to 69.2 +/- 12.1 mm VAS) after treatment. No significant change was noted (84.5 +/- 5.8 mm VAS and 83.5 +/- 8.9 mm VAS, respectively) in group 2. CONCLUSIONS: TENS was found to be effective and rapid in reducing pain during emergency transport of patients with acute low back pain and should be considered due to its ease of use and lack of side effects in the study population.
