Māori consistently have poorer health outcomes compared to non-Māori within Aotearoa. Numerous worldwide studies demonstrate that ethnic minorities receive less
We recently performed a clinical trial comparing motor sparing blocks (MSB) to periarticular infiltration (PAI) following total knee arthroplasty (TKA). We found that MSBs provided longer
Dexmedetomidine, an alpha 2 agonist, has been approved for providing sedation in the intensive care unit. Along with sedative properties, it has analgesic activity through its highly selective action on alpha 2 receptors. Recent studies have examined the use of dexmedetomidine as an adjuvant to prolong the duration of peripheral nerve blocks. Studies showing effectiveness of dexmedetomidine for adductor canal block in knee surgery are small. Also, its effectiveness has not been compared to Epinephrine which is a strong alpha and beta receptor agonist. In a previous study, we showed that motor sparing knee blocks significantly increased the duration of
Pain immediately following total knee arthroplasty (TKA) is often severe and can inhibit patients' rehabilitation. Recently, adductor canal blocks have been shown to provide adequate
Femoral nerve block (FNB) following total knee arthroplasty (TKA) has had mixed results with some studies reporting improvement in pain and reduced narcotic exposure while others have not shown substantial differences. The effect of a FNB on rehabilitation indices (quadriceps strength, knee flexion) is also unclear. The study purpose was to compare the effect of FNB+ a multimodal analgesic protocol (MMA) to MMA only on the 1) development of a complete quadriceps motor block and 2) knee flexion during the first two postoperative days and 3) knee flexion out to 12 weeks after primary TKA. Secondarily, we compared hospital length of stay (LOS), postoperative pain, analgesic use and the incidence of nausea/vomiting. This was a controlled clinical trial undertaken at two tertiary hospitals that do high annual TJA volumes (>200 cases). Both hospitals followed the same regional clinical pathway for preoperative, perioperative and postoperative care. The pathway started mobilization on the day of surgery with a goal for discharge home on the third postoperative day. At one site, FNB was used for the first two postoperative days in addition to MMA as needed (FNB group [n=19]) while the other site used standardized MMA (MMA group [n=20]) only. The presence of a complete quadriceps block, knee flexion, pain, analgesic use, incidence of nausea and vomiting were recorded daily in hospital. Hospital LOS was also recorded and knee flexion and pain were assessed at two, six and 12 weeks post discharge.Purpose
Method
Introduction. Fast track arthroplasty regimens require preservation of motor power to perform early rehabilitation and ensure early discharge (1). Commonly performed nerve blocks like femoral and Sciatic nerve blocks results in motor weakness thereby interfering with early rehabilitation and may also predispose to patient falls (2, 3). Hence, targeting the terminal branches of the femoral and sciatic nerves around the knee joint under ultrasound is an attractive strategy. The nerve supply of interest for knee
Background. Continuous epidural anesthesia or femoral nerve block has decreased postoperative pain after total knee arthroplasty to some extent. Although the established efficacy of these pain relief method, some adverse events such as hematoma or muscle weakness are still problematic. Intraoperative local infiltration of
Hemiarthroplasty and proximal femoral fixation are common procedures performed in trauma units, but there is very little information regarding post-operative pain experience. Pain control is a keystone in the successful management of hip fractures. A sound strategy of pain management is easier to implement in patients where pain levels can be predicted, allowing for an effective balanced analgesic regime. Analysis was performed on patients presenting with a hip fracture in two hospitals. Patients with a diagnosis of dementia were excluded. Post-operative pain scores were taken from patient observation charts using a verbal analogue scale. Post-operative opiate consumption was calculated from inpatient drug charts. 357 patients were included, 205 patients underwent a cemented hemiarthroplasty (HG) and 152 had fixation with a dynamic hip screw (DG). No significant difference was found in the length of hospital stay. HG patients recorded a mean morphine requirement of 20.2mg compared with 40.3mg for the DG group. Although the early pain score difference was significant (p=0.009), after 4 days, the scores were equivalent. This may support the notion of non-surgical factors determining the total length of hospital stay. The reason for the elevated pain scores and higher morphine requirement in the DHS group remains unclear. One theory is the fracture site still exists, and it is possible that pre-existing hip arthritis may continue to be symptomatic. It is important to recognise the difference in pain experienced between the groups and

Regional anaesthesia is integral to best practice
Introduction. External fixation (EF) devices are commonly used in the management of complex skeletal trauma, as well as in elective limb reconstruction surgery for the management of congenital and acquired pathology. The subsequent removal of an EF is commonly performed under a general anaesthetic in an operating theatre. This practice is resource intensive and limits the amount of operating theatre time available for other surgical cases. We aimed to assess the use of regional anaesthesia as an alternative method of
Introduction. Compartment syndrome can be a life changing consequence of injury to a limb. If not diagnosed and treated early it can lead to permanent disability. Neurovascular observations done on the ward by nursing staff, are often our early warning system to those developing compartment syndrome. But are these adequate for detecting the early signs of compartment syndrome? Our aim was to compare the quality and variability of charts across the UK major trauma network. Materials & Methods. All major trauma centres in England and Scotland were invited to supply a copy of the neurovascular chart routinely used. We assessed how such charts record relevant information. Specific primary data points included were pain scores,
Hallux valgus surgery can result in moderate to severe post-operative pain requiring the use of narcotic medication. The percutaneous distal metatarsal osteotomy is a minimally invasive approach which offers many advantages including minimal scarring, immediate weight bearing and decreased post-operative pain. The goal of this study is to determine whether the use of narcotics can be eliminated using an approach combining multimodal
Ankle fractures are common orthopedic injuries, often requiring operative intervention to restore joint stability, improve alignment, and reduce the risk of post-traumatic ankle arthritis. However, ankle fracture surgeries (AFSs) are associated with significant postoperative pain, typically requiring postoperative opioid analgesics. In addition to putting patients at risk of opioid dependence, the adverse effects of opioids include nausea, vomiting, and altered mental status which may delay recovery. Peripheral nerve blocks (PNBs) offer notable benefits to the postoperative pain profile when compared to general or spinal anaesthesia alone and may help improve recovery. The primary objective of this quality improvement (QI) study was to increase PNB administration for AFS at our institution to above 50% by January 2021. A root cause analysis was performed by a multidisciplinary team to identify barriers for PNB administration. Four interventions were chosen & implemented: recruitment and training of expert anesthesiologists in regional anesthesia techniques, procurement of additional ultrasound machines, implementation of a dedicated block room with training to create an enhanced learning environment, and the development of an educational pamphlet for patients outlining strategies to manage rebound pain, instructions around the use of oral multimodal
Total Knee Arthroplasty (TKA) is a successful treatment for end stage osteoarthritis of the knee joint. However, post-operative pain can lead to patient dissatisfaction and poorer outcomes. Cooled radiofrequency nerve ablation (CRNA) has reportedly been effective at treating pain osteoarthritic knee pain by targeting the periarticular nerves of the knee. We undertook a prospective, controlled pilot study to determine if CRNA provides effective post-operative
Abstract. Aim. This study was aimed to look into factors responsible for delayed mobilization after lower limb arthroplasty and effect on length of stay. Methods. It is an observational study conducted at Kings Mill Hospital from August to October 2021. All patients undergoing primary knee or hip arthroplasty were included in the study, while patients with revision surgeries were excluded. A proforma was designed to record demographics and different variables including medications, type of anaesthesia, orthostatic hypotension, dizziness, preop and post op pain score, fall in haemoglobin,
Abstract. Objectives. To determine the effectiveness of LIA compared to ACB in providing pain relief and reducing opiates usage in hamstring graft ACL reconstructions. Materials and Methods. In a consecutive series of hamstring graft ACL reconstructions, patients received three different regional and/or anaesthetic techniques for pain relief. Three groups were studied: group 1: general anaesthetic (GA)+ ACB (n=38); group 2: GA + ACB + LIA (n=31) and group 3: GA+LIA (n=36). ACB was given under ultrasound guidance. LIA involved infiltration at skin incision site, capsule, periosteum and in the hamstring harvest tunnel. Analgesic medications were similar between the three groups as per standard multimodal
Interscalene brachial plexus block is the standard regional analgesic technique for shoulder surgery. Given its adverse effects, alternative techniques have been explored. Reports suggest that the erector spinae plane block may potentially provide effective
Introduction. Day stay surgery for anterior cruciate ligament (ACL) reconstructions is an increasingly common practice and has driven clinicians to come up with postoperative pain regimes that allow same day mobilisation and a safe and timely discharge. There is a paucity of literature surrounding the use of intraosseous (IO) ropivacaine used as a Bier's block to provide both intraoperative and postoperative
Excessive postoperative opioid prescribing is a significant contributor to the opioid crisis. Prescribing in orthopaedic surgery is often further complicated by high use of opioid-based preoperative
