Comparative study between surgical wound catheter, femoral nerve block, and adductor canal block for postoperative analgesia after knee arthroplasty: A double blind randomized clinical trial.

Objectives: The present study compared the surgical wound catheter (SWC), femoral nerve block (FNB), and adductor canal block (ACB) for postoperative analgesia after knee arthroplasty. Methods: The study included (180) patients scheduled for unilateral total knee replacement and were randomly allocated into three groups. Patients received postoperative analgesia via continuous infusion of ropivacaine 0.2% (10 ml bolus followed by continuous infusion of 5 ml/hour) through the SWC, FNB, or ACB groups. All groups received supplemental analgesia by IV morphine using patient controlled analgesia. Pain scores were assessed at rest and during movements, the worst and least pain scores, and how often were in worst pain during the first 72 hours. The functional activity and patient's satisfaction were also recorded. Results: The study showed significant reductions in pain scores at rest and during movements in all groups compared to the baseline scores. Significant reductions in pain scores were observed in both ACB and FNB groups compared to the SWC group (P < 0.05). The worst pain scores were (6.15 ± 2.9, 5.85 ± 2.7, and 5.025 ± 1.513), least pain scores (2.06 ± 0.72, 1.92 ± 1.34 and 1.89 ± 1.76), percentage of time in worst pain (17.67 ± 9.15, 11.42 ± 7.50, and 9.8.8 ± 8.14) and the total morphine consumption (39.24 ± 6.82, 34.55 ± 7.86, and 26.40 ± 8.47 mg) in the SWC, FNB, and ACB groups, respectively. Functional assessments and patient's satisfaction, at 6 and 24 hours, were significantly better in ACB followed by SWC, and lastly FNB group (P < 0.5). No significant differences in the incidence of side effects (P > 0.05). Local anesthetic leak from the SWC was a continuous concern by the orthopedic surgeons. Conclusions: In terms of efficiency, ACB provided the highest quality of analgesia in terms of pain relief, functional activity, and patient's satisfaction. Both ACB and FNB provided higher quality of analgesia compared to the SWC. While ACB and SWC provided better functional improvements compared to FNB.

Foot health and quality of life among adults in Riyadh, Saudi Arabia: a cross-sectional study.

BACKGROUND: Foot conditions are frequent among the Saudi population. However, little is known regarding the effects of foot health on quality of life among the general Saudi population. This study aimed to assess foot health status, general health, and quality of life among the population of Riyadh using the Foot Health Status Questionnaire (FHSQ). METHODS: In this cross-sectional study, out of the total number of participants approached, using a preset questionnaire, by trained medical students to participate in this study, 398 met the inclusion criteria. The questionnaire started with an informed consent followed by a set of questions regarding the sociodemographic and past medical characteristics of the participants. Foot health and overall health were assessed using a FHSQ. RESULTS: A statistically significant positive correlation was observed between all the FHSQ domains, except for footwear. The strongest correlation was observed between foot pain and foot function, foot pain and general foot health, and foot function and general foot health. A statistically significant positive correlation was observed between general foot health and general health, vitality, social function. Our results also showed that foot pain, general foot health, vitality, and social function scores were significantly lower in women as compared to men. CONCLUSION: Significant positive correlation was observed between poor foot health and declining quality of life; thus, it is crucial to increase society's awareness of the importance of medical foot care and continuous follow-up and consequences if left unrecognized and untreated. This is a major domain that can improve the well-being and quality of life of a population.

High-resolution ultrasound as an aid in the diagnosis and treatment of post-brachioplasty injury to the medial brachial and the medial antebrachial nerves - Two case reports.

INTRODUCTION: Injury to the medial brachial and the medial antebrachial nerves may occur after brachioplasty and may lead to severe pain. We report on two cases to demonstrate that high-resolution ultrasound may be used as an aid in the diagnosis and treatment of post-brachioplasty injury to these small cutaneous nerves. CASE REPORTS: We report on two cases. The first case was a 29-year old female with severe arm pain secondary to a neuroma of the right medial brachial nerve. The diagnosis of a neuroma was done using high-resolution ultrasound and proximal nerve block led to immediate complete relief of pain. Recurrent but milder pain occurred and this was treated with multiple nerve blocks. The second case was a 34-year-old female with severe arm/forearm pain secondary to entrapment of the left medial antebrachial cutaneous nerve by a suture in the middle arm. The diagnosis was reached using high-resolution ultrasound and proximal nerve block led to immediate complete relieve of pain. Recurrent but milder pain occurred and this was treated by surgical nerve decompression. DISCUSSION: Previous literature confirms that high-resolution ultrasound can accurately identify small sensory nerves of the arm and forearm. CONCLUSION: We demonstrate that high resolution ultrasound may be used as an aid in the diagnosis and treatment of post-brachioplasty injury to the medial brachial and the medial antebrachial nerves. Proximal nerve block is extremely effective to relief the severe pain in these patients. However, recurrence of pain is expected and further management may be done by a trial of repeated injections or by surgical exploration.

Ultrasound imaging accurately identifies the intercostobrachial nerve.

OBJECTIVE: To test the hypothesis that identification and blockade of the intercostobrachial nerve (ICBN) can be achieved under ultrasound (US) guidance using a small volume of local anesthetic. METHODS: Twenty-eight adult male volunteers were examined at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia from November 2012 to September 2013. Intercostobrachial nerve blockade was performed using one ml of 2% lidocaine under US guidance. A sensory map of the blocked area was developed relative to the medial aspect of the humeral head. RESULTS: The ICBN appears as a hyper-echoic structure. The nerve diameter was 2.3±0.28 mm, and the depth was 9±0.28 mm. The measurements of the sensory-blocked area relative to the medial aspect of the humeral head were as follows: 6.3±1.6 cm anteriorly; 6.2±2.9 cm posteriorly; 9.4±2.9 cm proximally; and 9.2±4.4 cm distally. Intercostobrachial nerve blockade using one ml of local anesthetic was successful in all cases. CONCLUSION: The present study described the sonographic anatomical details of the ICBN and its sensory distribution to successfully perform selective US-guided ICBN blockade.

Efficacy of ultrasound-guided transversus abdominis plane (TAP) block for postcesarean section delivery analgesia--a double-blind, placebo-controlled, randomized study.

BACKGROUND: Ultrasound-guided transversus abdominis plane (TAP) block has been used for intra-operative and postoperative analgesia. Here we evaluate the efficacy of TAP block for postoperative cesarean delivery analgesia. METHOD: A randomized, double-blind, placebo-controlled trial was performed at King Khalid University Hospital on 40 patients undergoing cesarean delivery under spinal anesthesia with bupivacaine and fentanyl. At the end of surgery they received bilateral ultrasound-guided TAP block either with bupivacaine 0.25% (B group) 20 patients, or saline (S group, or placebo group) 20 patients, followed by patient controlled analgesia with i.v. morphine only. Each patient was assessed 24 hours after delivery for pain, morphine consumption, nausea, vomiting, sedation, patient's satisfaction, and also pain relief during mobilization (24 hours post-cesarean section). RESULTS: All 40 participants completed the study. Total morphine consumption was reduced more than 60% in the bupivacaine group; the bupivacaine group also reported improved satisfaction with their pain relief over 24 hours after surgery, reduced morphine consumption, less nausea, vomiting, and better patient's satisfaction. CONCLUSION: Ultrasound-guided TAP block improved postoperative analgesia, reduced morphine consumption and improved patient's satisfaction regarding analgesia after cesarean delivery.
