ABSTRACT

Background and Aims: Knee support, frequently made from sponge, is used to reduce injury. Sponge has less elasticity and durability compared with natural rubber. To our knowledge, there was no study that demonstrated the effectiveness of natural rubber and sponge in prevention of injury in children with bleeding disorders. The study aimed to demonstrate the effectiveness and satisfaction of natural rubber knee support compared with sponge knee support among children with bleeding disorders. Methods: The study consisted of three phases: (I) measuring reduced compression force, (II) producing size-appropriate knee support prototypes, and (III) conducting a randomized crossover trial, including 8 weeks wearing natural rubber knee support and sponge knee support with a 4-week wash-out period. The number of knee bleeds and user satisfaction were recorded. Results: A better compression force reduction in natural rubber (60%) than sponge (12%) was demonstrated. Knee support comprised a body part, made from natural-stretchable cotton and a protection part, made from either natural rubber or sponge. They were produced in four sizes: S, M, L, and XL and appropriately applied to 42 patients (21 hemophilia, 21 platelet disorders) with a mean (SD) age of 7.0 (2.9) years. The results from randomization showed no significant difference in the number of knee bleeds between the two knee support groups (10 vs. 7, p = 0.37). In terms of satisfaction score, the natural rubber knee supports were more durable (45.2% vs. 23.8%, p = 0.04) and easier to use (28.5% vs. 14.3%, p = 0.03). In addition, a higher percentage of parents chose natural rubber knee support when compared with sponge knee supports (71.0% vs. 29.0%, p = 0.006). Conclusion: Natural rubber knee support showed comparable effectiveness in the prevention of knee bleeding but was superior to sponge knee support in compression force reduction and satisfaction.

ABSTRACT

Purpose: To assess improvements in the validity and reliability of novices' skills in performing ultrasonography for airway assessment. Patients and Methods: A learning cohort study was conducted with 20 anesthesiology residents and 10 volunteers in the Department of Anesthesiology, Faculty of Medicine, Prince of Songkla University. The four parameters of airway assessment were soft tissue thickness at the level of 1) hyoid bone (STT-HY), 2) true vocal cords (STT-VC), 3) thyroid isthmus (STT-TI), and 4) suprasternal notch (STT-SN). The magnitude of discrepancies between the residents' and experienced anesthesiologists' measurements was evaluated over the sequence of measurements in the 10 volunteers. Results: The mean ultrasonic measurements of STT-HY by the experienced anesthesiologists and residents were significantly different (11.09 ± 3.14 mm vs 8.53 ± 3.02 mm, respectively; P = 0.008), whereas measurements of STT-VC, STT-TI, and STT-SN were not (7.18 ± 1.70 vs 7.14 ± 1.93, P = 0.32; 7.81 ± 2.14 vs 7.73 ± 2.19, P = 0.62; and 11.32 ± 3.33 vs 10.30 ± 3.02, P = 0.35, respectively). The mean discrepancy between the residents' and experienced anesthesiologists' measurements was close to zero throughout the sequence of measurements of STT-TI and STT-VC. However, the residents' measurements of STT-HY and STT-SN were considerably lower than those of anesthesiologists. The range of discrepancies between residents and experienced anesthesiologists in each sequential measurement was wide for all measurements, particularly for the measurement values of STT-HY, and the standard deviation of the discrepancies did not decrease over the sequence of measurements. Conclusion: Over the sequence of measurements for airway assessment in 10 volunteers by 20 residents in this learning trial, we found no evidence of improvement in measurement accuracy. Discrepancies between the residents' and anesthesiologists' measurements and the variability in discrepancy across residents were greatest in the measurement of STT-HY.

ABSTRACT

BACKGROUND: Thoracic epidural placement (TEP) using the conventional anatomic landmark-based technique is technically challenging, may require multiple attempts, and is associated with a high failure rate (12-40%). We hypothesized that real-time ultrasound guidance would be superior in the "first-pass" success rate of TEP, when compared with the conventional technique. METHODS: This prospective, randomized, superiority trial was conducted in a University hospital, and recruited 96 patients undergoing elective major abdominal or thoracic surgery and scheduled to receive a TEP for postoperative analgesia. Patients were randomly allocated to receive TEP using either the conventional technique (Gp-Conv, n = 48) or real-time ultrasound guidance (Gp-Usg, n = 48). The success of TEP was defined as eliciting loss of resistance technique and being able to insert the epidural catheter. The primary outcome variable was the "first-pass success rate" meaning the successful TEP at the first needle insertion without redirection or readvancement of the Tuohy needle. The secondary outcomes included the number of skin punctures, number of attempts, the overall success rate, TEP time, and total procedure time. RESULTS: The first-pass success rate of TEP was significantly higher (p = 0.002) in Gp-Usg (33/48 (68.8%); 95%CI 55.6 to 81.9) than in Gp-Conv (17/48 (35.4%); 95%CI 21.9 to 49.0). There was no statistically significant difference (p = 0.12) in the overall success rate of TEP between the 2 study groups (Gp-Usg; 48/48 (100%) vs. Gp-Conv; 44/48 (91.7%); 95%CI 83.9 to 99.5). Ultrasound guidance reduced the median number of skin punctures (Gp-Usg; 1 [1, 1] vs Gp-Conv; 2 [1, 2.2], p < 0.001) and attempts at TEP (Gp-Usg; 1 [1, 2] vs Gp-Conv; 3 [1, 7.2], p < 0.001) but the procedure took longer to perform (Gp-Usg; 15.5 [14, 20] min vs Gp-Conv; 10 [7, 14] min, p < 0.001). CONCLUSIONS: This study indicates that real-time ultrasound guidance is superior to a conventional anatomic landmark-based technique for first-pass success during TEP although it is achieved at the expense of a marginally longer total procedure time. Future research is warranted to evaluate the role of real-time ultrasound guidance for TEP in other groups of patients.

ABSTRACT

OBJECTIVE: Gabapentin has an antipruritus effect, which its efficacy in reducing pruritus induced by intrathecal morphine has not been well documented. The purpose of the present study was to know if a single smaller dose of gabapentin could decrease the intrathecal morphine-induced pruritus. MATERIAL AND METHOD: One hundred sixty eight patients from the 180 recruited patients fulfilled the trial requirement and were scheduled for orthopedic surgery under spinal anesthesia using 0.5% isobaric bupivacaine and 0.2 mg preservative-free morphine. The patients were divided into two groups, each of 84 subjects and received either gabapentin 600 mg or a placebo, two hours preoperatively, in a prospective, randomized, double-blind, placebo-controlled trial. The pruritus was evaluated at 1, 2, 3, 4, 6, 9, 12 and 24 hours after intrathecal morphine administration. Adverse events were noted. RESULTS: The overall incidence of pruritus was not significantly different between the two groups while the incidence and severity of pruritus was significantly decreased in the gabapentin group at four hours after intrathecal morphine injection (18 of 84 subjects, 21.4% vs. 35 of 84 subjects, 41.7%; p = 0.008 and 0.045 respectively). The urinary retention was significantly higher in the study group compared to the placebo group (50.0% (42 of 84 subjects) vs. 33.3% (28 of 84 subjects) p = 0.042). CONCLUSION: Preoperative gabapentin 600 mg did not significantly reduce the postoperative intrathecal morphine-induced pruritus.

ABSTRACT

PURPOSE: To describe the documentation of pain assessment and management in the first 72 hrs postoperatively. DESIGNS: Retrospective descriptive study MATERIAL AND METHOD: Four hundred and twenty five hospital charts in December 2002 were audited to reveal the quality of postoperative pain assessment and documentation. Scores above 21 from the possible maximum of 28 (75%) were accepted for the review. RESULTS: Nurses documented pain assessment more often than doctors (98.8% vs 29.4%). An assessment of pain intensity using a numerical rating scale (0 to 10) was found in 192 (45.2%) charts, and using a pain descriptor scale in 408 (96%) charts. The documentation of pain both before and after giving analgesics was scarce during the first 3 days postoperatively. Apart from charts that used a patient-controlled analgesia (PCA) technique which had a specific record form, regular pain assessment every 2 to 4 hrs during the first 24 hrs was found in only 2 (0.5%) charts. Pain assessment items which were documented inconsistently and below accepted standards were pain assessment after administration of analgesics, pain assessment every 2 hours in the first 24 hours (day 1), and pain assessment thereafter every 4 hours in the first 24-72 hours (days 2 and 3). The other 4 of 7 audit pain items were documented in higher scores: initial patients' pain intensity and sedation assessment, pain treatment, continuity of pain assessment and pain assessor s name scores. Nevertheless, because of the low total audit score [mean+/-SD = 10.7+/-3 out of 28], it was considered that none of the reviewed charts reflected good quality pain assessment and documentation. CONCLUSION: The present study revealed that the existing practices of pain assessment and documentation were poor. The need for development of regular pain assessment as if pain is the fifth vital sign should be widely emphasized as a part of quality assurance.
