Effects of Two Music Therapy Methods on Agitation and Anxiety among Patients Weaning off Mechanical Ventilation: A Pilot Study / 기본간호학회지

PURPOSE: The feasibility and differential effects of two music therapy methods (interventions with preferred music vs. classical relaxation music) were done to examine the effects on agitation and anxiety in patients weaning off mechanical ventilation. METHODS: This pilot study was conducted using a crossover design. Six patients listened to preferred music choices and classical relaxation music. Anxiety scores were measured using the Richmond Agitation Sedation Scale (RASS), State-Trait Anxiety Inventory (STAI), and visual analog scale (VAS). RESULTS: Patients showed a significant decrease in agitation and anxiety after both the preferred and classical relaxation music interventions. The difference in the effects of preferred music and that of classical relaxation music was not significant. As for feasibility, patients exhibited a change in agitated behaviors after the music interventions by not trying to take off medical devices and quietly listening to the music, and by smiling and moving lips along with the lyrics while listening. CONCLUSION: Music interventions which centered on either patients' preferences or classical relaxation music to enhance relaxation, helped reduce agitation and anxiety during the mechanical ventilation weaning process.

A Prospective Randomized Study Comparing Effectiveness of Local Anesthesia Techniques in Patients undergoing Transrectal Ultrasound-guided Prostate Biopsy / 대한비뇨기과학회지

PURPOSE: This study was designed to compare the effectiveness of intrarectal lidocaine gel versus periprostatic lidocaine injection during TRUS-guided biopsies. MATERIALS AND METHODS: From April 2003 to September 2003, 90 men undergoing a transrectal prostate biopsy were randomized into three groups. In group 1, 30 patients intrarectally received 20ml of 2% lidocaine gel; and group 2, 30 patients received 5ml(2.5ml per side) of 2% lidocaine solution injected along each side of the prostate, near the junction of the seminal vesicle and the base of the prostate(along the neurovascular bundles); in group 3, 30 patients received 5ml(2.5ml per side) of normal saline injected along the neurovascular bundles. The pain level after the biopsy was assessed using a 10-point linear visual analog pain scale(VAS). A statistical analysis was performed using the Wilcoxon Rank Sum test, and the results compared. RESULTS: Patient who received lidocaine solution injections along the neurovascular bundles (Group 2) had significantly lower VAS scores compared to the control group(mean score 3.56+/-2.13 versus 5.83+/-1.94, p<0.0001), but patients who received intrarectal lidocaine gel did not (mean score 5.46+/-2.70 versus 5.83+/-1.94, p=0.671). Gross hematuria, rectal bleeding and hemospermia occurred in 36(40.0%), 6(6.7%) and 5(5.6%) subjects, respectively. One patient had a vasovagal syncope. No patient reported febrile UTI or urinary retention. CONCLUSIONS: Bilateral nerve blockade with local anesthetic is a safe technique that significantly reduces pain during a prostate biopsy. However, in this study, intrarectal lidocaine injection did not reduce the pain compared to the control group during the prostate biopsy.
