Observational study.
This multi-site, observational, prospective study aims to investigate current practice and associated outcomes for patients scheduled for elective unilateral total hip or knee arthroplasty in South Africa.This information will provide baseline values, against which effects of implementing a multidisciplinary enhanced care protocol for arthroplasty patients will be compared (the subsequent study).
With ongoing advancements in healthcare leading to prolonged life expectancy, orthopedic surgeries are increasingly performed in elderly patients. Total knee arthroplasty, in particular, has been increasing with the growing demand for improved mobility and quality of life. Total knee arthroplasty is performed on patients with advanced and painful osteoarthritis of the knees, but it can result in moderate to severe postoperative pain during the recovery period. To relieve anxiety or stress during surgery under regional anesthesia, sedation can be provided. Dexmedetomidine is a sedative-analgesic agent acting as α2-adrenergic receptor agonist, and its analgesic effect has been well established in various procedures or surgeries. Magnesium has been reported to produce important analgesic effects including the suppression of neuropathic pain, potentiation of morphine analgesia, and attenuation of morphine tolerance. Although the exact mechanism is not yet fully understood, the analgesic properties of magnesium are believed to stem from regulation of calcium influx into the cell and antagonism of N-methyl-D-aspartate (NMDA) receptors in the central nervous system. In this study, investigators will evaluate the reducing effect of magnesium on the post-total knee arthroplasty pain in patients sedated with dexmedetomidine under spinal anesthesia.
Pain after a knee replacement can impair recovery and use of the new knee. Having an injection to numb the femoral nerve is known to give good pain relief after the operation but may lead to slower mobilisation as it also prevents the patient from moving the knee. Recent studies have shown that infiltration of local anaesthetic (LIA) within the new knee joint may also give good pain relief. The null hypothesis is that there is no difference in primary or secondary outcome measures between femoral nerve block and LIA, as anaesthetic techniques for knee replacement.
The purpose of this study is to compare condition oriented whole person Health Coaching along with the provision of decision aids to decision aids without condition oriented Health Coaching to neither condition oriented health coaching nor decision aids on medical cost, preference sensitive surgeries and measures of subject knowledge, decision process and decision quality.
