Effects of general and spinal anesthesia on postoperative rehabilitation in older adults after lower limb surgery: a retrospective cohort study.

Objective: To investigate the effects of perioperative general anesthesia (GA) and spinal anesthesia (SA) on postoperative rehabilitation in elderly patients with lower limb surgery. Methods: This retrospective propensity score-matched cohort study included patients aged 65 years or older who underwent lower limb surgery between January 1, 2020, and May 31, 2023. The GA and SA were selected at the request of the orthopedic surgeon, patient, and their family members. The main outcomes included the incidence of the patient's inability to self-care at discharge, postoperative complications including pulmonary infection, thrombus of lower extremity veins, infection of incisional wound and delirium, length of hospital stay, and incidence of severe pain in the first 2 days postoperatively. Results: In total, 697 patients met the inclusion criteria, and 456 were included in the final analysis after propensity score matching. In the GA and SA groups, 27 (11.84%) and 26 (11.40%) patients, respectively, could not care for themselves at discharge. The incidence rates did not differ between the groups (p = 0.884). In contrast, the incidence of postoperative complications (GA: 10.53% and SA: 4.39%; p = 0.013) and the length of hospital stay (GA: 16.92 ± 10.65 days and SA: 12.75 ± 9.15 days; p < 0.001) significantly differed between the groups. Conclusion: The choice of anesthesia is independent of the loss of postoperative self-care ability in older patients (>65 years) and is not a key factor affecting postoperative rehabilitation after lower limb surgery. However, compared with GA, SA reduces the incidence of postoperative complications and a prolonged hospital stay. Thus, SA as the primary anesthetic method is a protective factor against a prolonged hospital stay.

Effect of ankle versus thigh tourniquets on post-operative pain in foot and ankle surgery.

BACKGROUND: Tourniquets are commonly used in elective extremity orthopaedic surgery to reduce blood loss, improve visualization in the surgical field, and to potentially reduce surgical time. There is a lack of consensus in existing guidelines regarding the optimal tourniquet pressure, placement site, and duration of use. There is a paucity of data on the relationship between the site of a tourniquet and postoperative pain in foot and ankle surgery. AIM: To explore the relationship between tourniquet site and intensity of post-operative pain scores in patients undergoing elective foot and ankle surgery. METHODS: Retrospective analysis of prospectively collected data on 201 patients who underwent foot and ankle surgery in a single institution was undertaken. Intraoperative tourniquet duration, tourniquet pressure and site, and postoperative pain scores using Visual Analogue Score were collected in immediate recovery, at six hours and at 24 h post-op. Scatter plots were used to analyse the data and to assess for the statistical correlation between tourniquet pressure, duration, site, and pain scores using Pearson correlation coefficient. RESULTS: All patients who underwent foot and ankle surgery had tourniquet pressure of 250 mmHg for ankle tourniquet and 300 mmHg for thigh. There was no correlation between the site of the tourniquet and pain scores in recovery, at six hours and after 24 h. There was a weak correlation between tourniquet time and Visual Analogue Score immediately post-op (r = 0.14, P = 0.04) but not at six or 24 h post-operatively. CONCLUSION: This study shows that there was no statistically significant correlation between tourniquet pressure, site and post-op pain in patients undergoing foot and ankle surgery. The choice of using a tourniquet is based on the surgeon's preference, with the goal of minimizing the duration of its application at the operative site.

Adding intrathecal midazolam to local anesthetics improves sensory and motor block and reduces pain score without increasing side effects in lower limb surgeries: A meta-analysis and systematic review.

This meta-analysis was done to investigate the role of intrathecal midazolam in lower limb surgeries regarding prolongation of spinal block, postoperative pain control and associated side effects. The included studies reported onset and duration of sensory and motor block, time to first request analgesia, 24h opioid consumption, postoperative pain control, and associated side effects following use of intrathecal midazolam for lower limb surgeries. This review was performed following the PRISMA guidelines and using the online databases, Medline, Science Direct, Google scholar and Cochrane library. We registered this review with the PROSPERO database (ID-CRD42022346361) in August 2022. A total of 10 randomised controlled trials were included in this meta-analysis. Our results showed patients receiving 1mg intrathecal midazolam showed significantly faster onset of sensory block [P=.001 (CI: -0.98, -0.31)]. Duration of sensory and motor block were also significantly prolonged in intrathecal midazolam group [P<.00001 (CI: 18.08, 39.12), P=.002 (CI: 0.45, 2). Intrathecal midazolam also increased the time to first request analgesia [P=.0003, (CI: 1.22, 4.14)]. Pain scores at 4 and 12h postoperatively were significantly lower in patients receiving intrathecal midazolam [P=.00001 (CI: -1.20, -0.47) and P=.05 (CI: -0.52, -0.01) respectively]. In conclusion, the addition of intrathecal midazolam to local anesthetics in lower limb surgeries results in early onset of sensory and motor block. It also increases the duration of sensory and motor block. The time to first request analgesia is increased. VAS pain scores at 4 and 12h postoperatively were also lower without any increased side effects.

The Classification Algorithms Applied to the Inpatient Stay for Lower Limb Surgery.

The revolutions of recent years in health care have involved several areas ranging from patient treatment to resource management. Therefore, several strategies have been put in place to increase patient value while trying to reduce spending. Several indicators have arisen to evaluate the performance of healthcare processes. The main one is Length of Stay (LOS). In this study, classification algorithms were used to predict the LOS of patients undergoing lower extremity surgery, an increasingly common condition given the progressive aging of the population. The context is the Evangelical Hospital "Betania" in Naples (Italy) in 2019-2020, which augments a multicenter study conducted by the same research team on several hospitals in southern Italy. All selected algorithms show an Accuracy above 90% but among them, the best is Logistic Regression with a value reaching 94%.

A Comparative Study of Analgesic Efficacy of Epidural Ropivacaine With Dexmedetomidine Versus Ropivacaine With Ketamine in Adult Patients Undergoing Elective Lower Limb Surgery.

INTRODUCTION: Adjuvating of the epidural block with local anaesthetics during lower limb surgeries improves Intraoperative as well as postoperative analgesia. A comparison of epidural ropivacaine plus dexmedetomidine (RD) versus ropivacaine plus ketamine (RK) was done in terms of quality of the motor and sensory blockade, changes in hemodynamic parameters, and efficacy of analgesia. METHODS:  A prospective randomized parallel double-blind study was conducted on 68 patients of the American Society of Anaesthesiologists (ASA) grade 1 and 2, ages 18 to 75 years, which were divided into two groups (RD and RK; 34 patients in each group). After receiving a loading dose through an epidural catheter consisting of 20ml of 0.5% ropivacaine, the epidural infusion was started after an hour of surgery at 5ml/hrs of 0.2% ropivacaine with 1µg/ml dexmedetomidine in Group RD and at 5ml/hrs of 0.2% ropivacaine with 0.5mg/ml ketamine in Group RK for 48 hours. Both groups were compared regarding the onset of sensory and motor block, resolution of sensory and motor block, hemodynamic parameters, analgesic efficacy, and total rescue analgesic requirement in 48 hours. RESULTS: A significant difference was observed in the time of resolution of sensory blockade which was 9.77±2.38 hrs in the RD group as compared to 7.79±1.82 hrs in the RK group (p-value 0.0003) and the time of resolution of motor block was 6.53±2.44 hrs in the RD group compared to 4.58±0.83 hrs in the RK group (p-value 0.001). CONCLUSIONS: Epidural dexmedetomidine significantly increases the duration of analgesia and duration of the motor blockade in comparison to ketamine.

Male Lower Extremity Sculpting.

BACKGROUND: The muscular sculpture (MS) is a new technique of male body contouring to achieve: tight skin that very well reveals muscular bulk, a male muscular and athletic body, minimal observable scars and even patients who are not, nor have been in. With this study, we describe the new technique for sculpting of lower extremities. In literature are not described techniques to accomplish a sound aesthetic result in sculpting surgery about lower extremities. METHODS: For this surgical procedure, we illustrate the technique that was obtained from 5 male patients (principles outlined in the Declaration of Helsinki have been followed). We describe this surgery with six steps: defatting step; MS; internal scar removal; irregularity removal; dermal grasping; last residues of fat removing. RESULTS: We obtain a high satisfaction rate as high as 100% for short and long term. Compared to the complications more described in literature (infection, hematoma, seroma, wound dehiscence, hypertrophic scars, sensory nerve injury and recurrent skin laxity, Monarca and Rizzo in Aesthetic Plast Surg 39(2):199-202, 2015), we have not had complications. We had no major complications. We observed, with our other studies, a direct relationship between complications and smoking habit. Successful body-contouring surgery requires a patient to embrace positive lifestyle habits: exercise, a proper diet and other positive lifestyle changes (Monarca et al. in Plast Reconstr Surg 123(5):1637-1638, 2009), and a high compliance and to avoid all the excesses. CONCLUSIONS: We obtain amazing aesthetic results with total patient satisfaction without complications. There are not enough studies in the literature about body sculpting, and is necessary to deepen this technique in order to obtain increasingly encouraging results.

Determinants of Post-Operative Cognitive Decline in Elderly People.

BACKGROUND: Surgery and anesthesia can result in temporary or permanent deterioration of the cognitive functions, for which causes remain unclear. OBJECTIVES: In this pilot study, we analyzed the determinants of cognitive decline following a non-emergency elective prosthesis implantation surgery for hip or knee. DESIGN: Prospective single-center study investigating psychomotor response time and changes in MoCA scores between the day before (D-1) and 2 days after (D+2) following surgery at the Lariboisière Hospital (Paris, France). PARTICIPANTS: 60 patients (71.9±7.1-year-old, 72% women) were included. MEASUREMENTS: Collected data consisted in sociodemographic data, treatments, comorbidities and the type of anesthesia (local, general or both). Furthermore, we evaluated pain and well-being before as well as after the surgery using point scales. RESULTS: Post-operative (D+2) MoCA scores were significantly lower than pre-operative ones (D-1) with a median difference of 2 pts [IQR]=4pts, (p<0.001), we found no significant difference between locoregional and general anesthesia. Pre-operative benzodiazepine or anticholinergic treatments were also associated to a drop in MoCA scores (p=0.006). Finally, the use of ketamine during anesthesia (p=0.043) and the well-being (p=0.006) evaluated before intervention, were both linked to a reduced cognitive impact. CONCLUSION: In this pilot study, we observed a post-operative short-term cognitive decline following a lower limb surgery. We also identified pre and perioperative independent factors linked to cognitive decline following surgery. In a next stage, a larger cohort should be used to confirm the impact of these factors on cognitive decline.

Total Spinal Anaesthesia: A Rare Complication of Psoas Compartment Block.

Psoas compartment block is an acceptable regional anaesthesia technique as a substitute to central neuraxial blockade for lower limb surgeries. Being a peripheral nerve block, it is considered relatively safe compared with the central neuraxial block. However, it can lead to some serious complications. Herein, we report a rare complication of total spinal anaesthesia following peripheral nerve stimulator-guided psoas compartment block.

A patient satisfaction survey investigating pre- and post-operative information provision in lower limb surgery.

BACKGROUND: Planned lower limb surgery is common, with over 90,000 hip replacements, 95,000 knee replacements and 15,000 anterior cruciate ligament reconstructions performed in the UK each year. These procedures are primarily indicated to treat osteoarthritis, sporting injuries and trauma. Patient satisfaction is an important element of healthcare provision, which is usually measured by functional outcomes but influenced by other factors. Few studies have assessed patients' views on the information given to them pertaining surgery and patients are infrequently consulted when designing leaflets and information packs, which can lead to confusion during the recovery period and poor long-term outcomes. Furthermore, previous studies have not directly asked patients what resources they would prefer, or which format would suit them best. This project aimed to assess if patients were satisfied with the information they received around their operations and to identify potential improvements. METHODS: Set in a National Health Service (NHS) run major trauma centre in the West Midlands, a multiple choice and free-text answer survey was administered to patients who used the orthopaedic service over the course of 1 month. Surveys were designed in Qualtrics and administered face-to-face on paper. Thematic content analysis was performed on the results. RESULTS: Eighty patients completed the survey, of which 88.8% of patients were satisfied with the information they received. Discussions with surgeons were the most useful resource and 53% of patients requested more internet resources. Post-operative patients were statistically more likely to be dissatisfied with information provision than pre-operative patients. Over 20% of the study population requested more information on post-operative pain and recovery timelines. CONCLUSIONS: Although patients were satisfied in general, areas for change were identified. Suggested resources took the form of webpages and mobile platforms. These resources could contain educational videos, patient experience blogs or interactive recovery timelines, to be of benefit to patients. These suggestions may enable NHS Trusts to "get into the digital age", however, more research on patient satisfaction around information provision and the impact it has on recovery and decision making is needed.

Cross-Cultural Validation of the Italian Version of the Bt-DUX: A Subjective Measure of Health-Related Quality of Life in Patients Who Underwent Surgery for Lower Extremity Malignant Bone Tumour.

The purpose of this study was to translate the English bone tumour DUX (Bt-DUX-Eng) questionnaire for lower extremity bone tumour patients, a disease-specific quality of life (QoL) instrument, into Italian and then examine the validity of the Italian version of Bt-DUX (Bt-DUX-It). The adaptation and translation process included forward translation, back-translation, and a review of the back-translation by an expert committee. The Bt-DUX-It was validated in a sample of adolescents treated for lower extremity osteosarcoma in Italy. Assessments included the Bt-DUX, the Toronto Extremity Salvage Score (TESS), and the European Organization for Research and Treatment Core Quality of Life Questionnaire of Cancer Patients (EORTC QLQ-C30). Fifty-one patients with a median age of 20 years (range: 15-25) completed the questionnaires. The mean Bt-DUX score was 70 (range: 16.30-100). The internal consistency of the overall score and that of the Bt-DUX-It was good: Cronbach's α was 0.95. Spearman's correlation coefficient between the Bt-DUX (total and domain scores) and EORTC QLQ C30 and TESS were overall moderate to good, reaching a p-value <0.01 in all cases. The Bt-DUX-It version is a useful tool for measuring QoL in patients with bone tumour and has similar internal consistency, construct validity, and discrimination as those of the Dutch and English versions.

Surgical treatment of insertional Achilles tendinopathy: results after removal of the subcutaneous bursa alone-a case series.

BACKGROUND: Insertional Achilles tendinopathy is well known to be difficult to treat, especially when there is intra-tendinous bone pathology. This study is a case series on patients with chronic insertional Achilles tendon pain and major intra-tendinous bony pathology together with bursa and tendon pathology, treated with excision of the subcutaneous bursa alone. METHODS: Eleven patients (eight men and three women) with a mean age of 44 years (range 24-62) and a chronic (>6 months) painful condition from altogether 15 Achilles tendon insertions were included. In all patients, ultrasound examination showed intra-tendinous bone pathology together with pathology in the tendon and subcutaneous bursa, and all were surgically treated with an open excision of the whole subcutaneous bursa alone. This was followed by full weight-bearing walking in a shoe with open heel for 6 weeks. RESULTS: At follow-up 21 (median, range 12-108) months after surgery, 9/11 patients (12/15 tendons) were satisfied with the result of the operation and 10/11 (13/15 tendons) were back in their previous sport and recreational activities. The median VISA-A score had improved from 41 (range 0-52) to 91 (range 33-100) (p<0.01). CONCLUSION: In patients with chronic painful insertional Achilles tendinopathy with intra-tendinous bone pathology, tendon and bursa pathology, open removal of the subcutaneous bursa alone can relieve the pain and allow for Achilles tendon loading activities. The results in this case series highlight the need for more studies on the pain mechanisms in insertional Achilles tendinopathy and the need for randomised studies to strengthen the conclusions. LEVEL OF EVIDENCE: IV Case series.

Fascia iliaca compartment block: How far does the local anaesthetic spread and is a real time continuous technique feasible in children?

BACKGROUND AND AIMS: The fascia iliaca compartment block (FICB) is commonly administered in children for anterolateral thigh surgery. The actual spread of the local anaesthetic (LA) beneath the fascial layers in children is not known. We hypothesised that in children there could be a possibility of the LA to reach lumbar plexus with the dose we used. METHODS: This study included 25 children, aged 1-15 years for lower limb surgeries after standardised general anesthesia, the FICB was done with ultrasonography. Radio-opaque dye was tagged to LA and the fluoroscopic study was performed. The catheter was placed under ultrasonography. The primary objective was to investigate the fluoroscopic demonstration of the extent of LA spread by our technique and drug volume which is not known in children. The secondary objectives were to evaluate the intraoperative and postoperative analgesic efficacy, complications if any, of the continuous FICB catheters placed by our method. RESULTS: In all patients, the visualisation of ilium and iliacus muscle, the fascia iliaca and needle tip was possible. The fluoroscopic imaging showed that the LA did not spread till the lumbar plexus in 20 patients. In 5 patients, delineated the psoas muscle and reached the L4 vertebral level. The analgesia was adequate. In the postoperative period, 92% had sufficient pain relief. Mild soakage was an issue with catheters. CONCLUSION: Although single shot fascia iliaca compartment block has limited spread of local anaesthetic in children, it is efficacious. Continuous fascia iliaca compartment block is feasible and effective in this age group.

Impact of ankle-foot orthoses on gait 1 year after lower limb surgery in children with bilateral cerebral palsy.

BACKGROUND:: Different types of ankle-foot orthoses are commonly used following lower limb surgery in children with bilateral spastic cerebral palsy. After three-dimensional gait analysis 1 year postoperatively, many children are recommended continued use of ankle-foot orthoses. OBJECTIVES:: Our aims were to quantify the impact of ankle-foot orthoses on gait 1 year postoperatively and evaluate predictors for clinically important improvement. STUDY DESIGN:: Prospective cohort study. METHODS:: A total of 34 ambulating children with bilateral cerebral palsy, with mean age 11 years (range 6-17), comprising 12 girls and 22 boys, were measured with three-dimensional gait analysis preoperatively (barefoot) and 1 year postoperatively (barefoot and with ankle-foot orthoses). Outcome was evaluated using gait profile score, key kinematic, kinetic and temporal-spatial variables in paired sample comparisons. Logistic regression was used to evaluate predictors for clinically important improvement with orthoses (⩾1.6° change in gait profile score). RESULTS:: Walking barefoot 1 year postoperatively, major improvements were seen in gait profile score and key variables. With ankle-foot orthoses, there were significantly improved step length and velocity, additional moderate reduction/improvement in gait profile score and knee moments and decreased stance ankle dorsiflexion compared to barefoot. Children using ground reaction ankle-foot orthoses ( n = 14) decreased stance knee flexion from 13.9° walking barefoot to 8.2° with orthoses. High gait profile score and more gait dysfunction preoperatively were significant predictors of clinically important improvement walking with orthoses. CONCLUSION:: The results indicate improved gait function walking with ankle-foot orthoses versus barefoot 1 year after lower limb surgery. Stronger impact of ankle-foot orthoses was found in children with more pronounced gait dysfunction preoperatively. CLINICAL RELEVANCE: The 1-year postoperative three-dimensional gait analysis is a useful method to assess treatment outcome after lower limb surgery in children with bilateral cerebral palsy and could also guide clinicians whether further treatment with ankle-foot orthoses is indicated, using clinically important differences as thresholds to evaluate their impact on gait.

Research priorities in children requiring elective surgery for conditions affecting the lower limbs: a James Lind Alliance Priority Setting Partnership.

OBJECTIVE: To identify and prioritise research questions concerning the elective surgical management of children with conditions affecting the lower limb by engaging patients, carers and healthcare professionals. DESIGN: A modified nominal group technique. SETTING: UK. PARTICIPANTS: 388 individuals (29 patients, 155 parents/carers, 204 healthcare professionals) were recruited through hospital clinics, patient charities and professional organisations and participated in the initial prioritisation survey; 234 individuals took part in the interim prioritisation survey. 33 individuals (3 patients, 9 parents/carers, 11 healthcare professionals, 7 individuals representing the project's steering group and 3 James Lind Alliance (JLA) facilitators) attended the final face-to-face workshop to rank the top 10 research priorities. INTERVENTIONS: Surveys were distributed using various media resources such as newsletters, internet messaging boards and the 'Paediatric Lower Limb Surgery Priority Setting Partnership (PSP) website. Printed copies of the questionnaire were also made available to families in outpatient clinics. OUTCOME MEASURES: Survey results, top 10 and top 26 priority rankings RESULTS: The process took 18 months to complete (July 2017-January 2019); 388 people generated 1023 questions; a total of 801 research questions were classified as true uncertainties. Following the JLA methodology, 75 uncertainties were developed from the initial 801 questions. Twenty six of those were selected through a second survey and were taken to the final face-to-face workshop where the top 10 research priorities were selected. The top10 priorities included questions on cerebral palsy, common hip conditions (ie, Perthes' disease and developmental dysplasia of the hip) as well as rehabilitation techniques and methods to improve shared decision-making between clinicians and patients/families. CONCLUSIONS: This is the first JLA PSP in children's orthopaedic surgery, a particularly under-researched and underfunded area. We have identified important research topics which will guide researchers and funders and direct their efforts in future research.

Comparative addition of dexmedetomidine and fentanyl to intrathecal bupivacaine in orthopedic procedure in lower limbs.

BACKGROUND: Spinal block is a common procedure for lower limbs surgery. Fentanyl, a synthetic opioid and dexmedetomidine, a selective α2 agonist have been used as adjuvants in spinal anesthesia to prolong intraoperative and postoperative analgesia. The aim of current study is to compare the efficacy of dexmedetomidine and fentanyl added to intrathecal bupivacaine in orthopedic procedures in lower limbs. METHODS: In this randomized clinical trial, 90 patients undergoing elective lower limb surgeries were randomly allocated to three groups. Via intrathecal approach, the patients received 2.5 ml hyperbaric bupivacaine 0.5% plus 5 micrograms dexmedetomidine (BD group), 25 micrograms fentanyl (BF group) or 0.5 ml normal saline (BN group), respectively. Time to reach the complete motor block, the highest sensory level, regression from block, analgesic request and duration of the drug effect, hemodynamic changes and side effects were compared between the groups. RESULTS: There was no significant difference between the groups regrading time to reach complete motor block, but time to reach the highest sensory level was shorter in group BD than group BF (6.28 ± 1.75 vs. 7.17 ± 1.45, p = 0.03). Group BD had significantly lower mean of NRS 6 h after operation (1.90 ± 0.84 vs. 6.16 ± 1.44 vs. 6.30 ± 1.17, p < 0.001) and longer duration to regress to Bromage 0 (331.60 ± 73.96 vs. 185.56 ± 35.87 vs. 147.03 ± 33.05 min, p < 0.001), to analgesic request (496.63 ± 70.19 vs. 296.33 ± 44.83 vs. 221.83 ± 22.26 min, p < 0.001), to regress two sensory levels (149.00 ± 23.17 vs. 88.90 ± 12.85 vs. 69.33 ± 6.67 min, p < 0.001) and to regress to S1 (560.53 ± 81.86 vs. 329.83 ± 44.10 vs. 241.83 ± 22.26 min, p < 0.001). Serial changes in SBP (p = 0.006), DBP (p = 0.03) and HR (p = 0.002) in group BF were significantly higher than the other two groups. The three groups had comparable side effects. CONCLUSIONS: Using dexmedetomidine as an adjuvant to bupivacaine for spinal anesthesia in lower limb surgeries has longer duration of sensory and motor block and longer postoperative analgesia. TRIAL REGISTRATION: IRCT registration number: IRCT2017041010599N15 , 24 May 2017.

Fascia iliaca compartment block versus no block for pain control after lower limb surgery: a meta-analysis.

BACKGROUND: The analgesic effect of fascia iliaca compartment block (FICB) versus no block (NB) after lower limb surgery (LLS) is still controversial, so we performed this meta-analysis. MATERIALS AND METHODS: By searching the PubMed, Embase and the Cochrane Library (last update by July 20, 2017), randomized controlled trials comparing the analgesic effect of FICB versus NB in patients receiving LLS were identified. The primary outcome was the pain scores at 4, 12, and 24 h after LLS. The dosage of morphine at 24 h was also collected. The side effect of anesthesia was assessed according to the occurrence rate of postoperative nausea and vomiting. RESULTS: Data from 7 clinical trials that included 508 patients were summarized. The results showed that patients receiving FICB had lower pain scores at 4 h (mean difference [MD]=-1.17; 95% CI=-2.30 to -0.05; P=0.041), 12 h (MD=-0.41; 95% CI=-0.76 to -0.05; P=0.026) and 24 h (MD=-0.96; 95% CI=-1.77 to -0.15; P=0.020) after LLS. Besides, FICB could reduce the dosage of morphine at 24 h (MD=-2.06; 95% CI=-3.82 to -0.30; P=0.022) and the incidence of postoperative nausea and vomiting (relative risk rate=0.44, 95% CI=0.24-0.80, P=0.008). CONCLUSION: Compared with NB, FICB is an effective and safe method for alleviating the pain after LLS. More high-quality randomized controlled trials are needed to confirm this finding.

A randomized controlled trial to assess the effect of a ketamine infusion on tourniquet hypertension during general anaesthesia in patients undergoing upper and lower limb surgery.

BACKGROUND: Tourniquet hypertension arising from tourniquet inflation remains a primary concern to the anaesthetist. One drug commonly used to manage tourniquet hypertension is ketamine. No studies have examined the effect of ketamine on tourniquet hypertension for a period of more than one hour or an infusion of the same. OBJECTIVE: To compare the effect of an intravenous infusion of ketamine versus placebo on tourniquet induced hypertension in patients undergoing upper and lower limb surgery under general anaesthesia. METHODS: Forty six adult patients scheduled for upper and lower limb surgery under general anaesthesia were randomized into two equal groups. The ketamine group received an intravenous bolus of 0.1mg/kg of ketamine followed by an infusion of 2ug/kg/min. The saline group received an intravenous bolus of physiological saline followed by an infusion of saline. All the patients were reviewed post-operatively. Data of the baseline characteristics, haemodynamic changes, post-tourniquet pain and side effects were collected. If post-tourniquet pain was present post-operatively, a visual analogue scale (VAS) was used to assess its severity. RESULTS: 46 patients successfully completed the trial. There were no significant differences between the groups for baseline patient demographics. The incidence of tourniquet hypertension was higher in the saline group (26.1%) compared with ketamine group (4.6%) with a 95% confidence interval. The difference was shown to be statistically significant ('P'<0.05). There was an increase in systolic blood pressure after 60 minutes of tourniquet inflation in the saline group but the difference was not statistically significant('P'>0.866). There were no significant differences between the groups as regards diastolic blood pressure and heart rate. VAS scores did not differ between the two groups. Statistically, there was no difference found between the two groups. Side effects were minimal in the ketamine group whilst in the saline group, nausea and vomiting were predominant but were also not statistically significant. CONCLUSION: Based on the results of this study, there was a difference in the proportion of tourniquet hypertension between the ketamine and saline groups for patients undergoing upper and lower limb orthopaedic surgery under general anaesthesia.

Meta-analysis and suggested guidelines for prevention of venous thromboembolism (VTE) in foot and ankle surgery.

PURPOSE: To perform a meta-analysis investigating venous thromboembolism (VTE) following isolated foot and ankle surgery and propose guidelines for VTE prevention in this group of patients. METHODS: Following a PRISMA compliant search, 372 papers were identified and meta-analysis performed on 22 papers using the Critical Appraisal Skills Programme and Centre for Evidence-Based Medicine level of evidence. RESULTS: 43,381 patients were clinically assessed for VTE and the incidence with and without chemoprophylaxis was 0.6% (95% CI 0.4-0.8%) and 1% (95% CI 0.2-1.7%), respectively. 1666 Patients were assessed radiologically and the incidence of VTE with and without chemoprophylaxis was 12.5% (95% CI 6.8-18.2%) and 10.5% (95% CI 5.0-15.9%), respectively. There was no significant difference in the rates of VTE with or without chemoprophylaxis whether assessed clinically or by radiological criteria. The risk of VTE in those patients with Achilles tendon rupture was greater with a clinical incidence of 7% (95% CI 5.5-8.5%) and radiological incidence of 35.3% (95% CI 26.4-44.3%). CONCLUSION: Isolated foot and ankle surgery has a lower incidence of clinically apparent VTE when compared to general lower limb procedures, and this rate is not significantly reduced using low molecular weight heparin. The incidence of VTE following Achilles tendon rupture is high whether treated surgically or conservatively. With the exception of those with Achilles tendon rupture, routine use of chemical VTE prophylaxis is not justified in those undergoing isolated foot and ankle surgery, but patient-specific risk factors for VTE should be used to assess patients individually. LEVEL OF EVIDENCE: II.

The effects of intravenous fosaprepitant and ondansetron in the prevention of postoperative nausea and vomiting in patients who underwent lower limb surgery: a prospective, randomized, double-blind study.

PURPOSE: Postoperative nausea and vomiting (PONV) is the most common complication after surgery, and opioid administration increases its incidence. We compared the preventive effects of fosaprepitant, a neurokinin-1 (NK1) receptor antagonist, with those of ondansetron on PONV in patients who underwent lower limb surgery with postoperative epidural opioid administration. METHODS: This prospective, double-blind, randomized study included 38 patients who underwent lower limb surgery. They were randomly allocated to receive intravenous fosaprepitant 150 mg (n = 19; NK1 group) or ondansetron 4 mg (n = 19; ONS group) before general anesthesia. All patients received postoperative epidural fentanyl for pain control. The incidence of nausea and vomiting, complete response rate (no vomiting and no rescue antiemetic use), rescue antiemetic use, nausea score (0-3), and visual analog scale (VAS 0-10) score for pain were recorded at 2, 24, and 48 h after surgery. RESULTS: No patient in the NK1 group experienced vomiting (0%) during the first 24 and 48 h after surgery, while 5 of 19 (26%) patients in the ONS group experienced this complication, indicating a significant difference between groups. There were no significant differences in the incidence of PONV, complete response rate, rescue antiemetic use, nausea score, and VAS score for pain between the NK1 and ONS groups during the study period. CONCLUSIONS: Fosaprepitant was more effective than ondansetron in decreasing the incidence of vomiting after lower limb surgery with postoperative opioid administration. Meanwhile, fosaprepitant was not inferior to ondansetron in decreasing the incidence and severity of PONV.

Athletic groin pain: a systematic review and meta-analysis of surgical versus physical therapy rehabilitation outcomes.

BACKGROUND: Athletic groin pain (AGP) is an encompassing term for the multitude of chronic conditions presenting as pain in the inguinal region. The purpose of this review was to compare the return to play rates (RTPrate) and return to play times (RTPtime) between surgical and rehabilitation interventions in the treatment of AGP. METHODS: A systematic review of English language peer review journals was carried out between 1980 to June 2013 using PubMed, Embase, CINHAL and Google Scholar searching for all papers relating to AGP (and its various pseudonyms) and all surgical and rehabilitative interventions which reported RTPrate and/or RTPtime. AGP literature has been subdivided by many eponymous diagnoses but anatomical diagnostic groupings of (1) abdominal wall, (2) adductor and (3) pubic related pain were used in this review. Meta-analysis was then carried out on the data to compare results between the surgical and rehabilitation groups. RESULTS: Fifty-six papers out of the 561 discovered in the initial search were included in the review with 3332 athletes included. Evidence was mostly level IV. Using the Black and Downs checklist we found poor study quality overall with a high risk of bias especially among surgical studies. The results showed comparable RTPrate between surgical and rehabilitative interventions within the three diagnostic groups. Rehabilitation had significantly quicker RTPtime for pubic related groin pain compared to surgery (10.5 weeks and 23.1 weeks respectively). The abdominal group had the fastest return of the three groups for the rehabilitation and surgery. CONCLUSIONS: The review suggested better outcomes with rehabilitation for pubic-related groin pain with no difference between the adductor and abdominal groups. The review highlighted the poor quality and risk of bias in the literature making accurate comparison difficult.
