The effect of intra-articular meperidine and bupivacaine 0.5 on postoperative pain of arthroscopic knee surgery; a randomized double blind clinical trial
Background: Arthroscopic knee surgeries have a painful postoperative course, which often necessitates acute pain management. Among different analgesia techniques, Intra-articular injection is the technique of choice for many pain specialists, based on its confined effect to the surgical site (knee), lack of systemic effects and promotion of safe early ambulation. Objectives: The aim of this study was to compare analgesic effects of intra-articular meperidine, bupivacaine 0.5 or their combination after knee arthroscopic surgery. Patients and Methods: Sixty ASA class I-II patients� candidates for arthroscopy knee surgery enrolled in a randomized double blind study to receive either 20 mL of bupivacaine 0.5; 100 mg meperidine (diluted in normal saline) or bupivacaine 0.5 along with 100 mg meperidine. A written informed consent was obtained from all patients. Postoperative analgesia duration, VAS at 2, 6, 12 and 24 hours, the Results: The bupivacaine-meperidine group had better duration of postoperative analgesia (P = 0.001), latter first analgesic request (P � first analgesic request time, total fentanyl consumption in first 24 hours, patients� satisfaction and adverse effects were recorded. 0.001), lower total fentanyl consumption in first 24 hours after the operation (P = 0.001), less mean VAS at 2 hours (P = 0.001) and more patients� overall satisfaction (P = 0.01) compared with each medication alone. VAS at 6, 12 and 24 postoperative hours were not different between the groups of study. No adverse effects were observed. Conclusions: Although postoperative intra-articular meperidine is a better alternative for bupivacaine, their combination could improve their analgesic effects compared with each other alone. © 2015, Iranian Society of Regional Anesthesia and Pain Medicine (ISRAPM)
Cross-cultural adaptation and validation of the Injury-Psychological Readiness to Return to Sport scale to Persian language
The aim of the present study was to develop and provide validation statistics for the Persian Injury-Psychological Readiness to Return to Sport scale (I-PRRS) following a cross-sectional and prospective cohort study design. The I-PRRS was forward/back-translated and culturally adapted into Persian language. The Persian I-PRRS was administered to 100 injured athletes (93 male; age 26.0 ± 5.6 years; time since injury 4.84 ± 6.4 months) and 50 healthy athletes (36 male; mean age 25.7 ± 6.0 years). The Persian I-PRRS was re-administered to 50 injured athletes at 1 week to examine test�retest reliability. There were no floor or ceiling effects confirming the content validity of Persian I-PRRS. The internal consistency reliability was good. Excellent test�retest reliability and agreement were demonstrated. The statistically significant difference in Persian I-PRRS total scores between the injured athletes and healthy athletes provides an evidence of discriminative validity. The Persian I-PRRS total scores were positively correlated with the Farsi Mood Scale (FARMS) total scores, showing construct validity. The principal component analysis indicated a two-factor solution consisting of �Confidence to play� and �Confidence in the injured body part and skill level�. The Persian I-PRRS showed excellent reliability and validity and can be used to assess injured athletes� psychological readiness to return to sport among Persian-speaking populations. © 2016 Taylor & Francis
