The Effect of Preoperative Opioid Dosage on Postoperative Outcomes in Patients Undergoing Knee Surgery.
Opioid prescription before knee replacement surgery is associated with longer hospital stays, more postsurgical pain, and a higher rate of complications. Despite the growing evidence against opioids, they remain popular preoperative pain management prescriptions. ⋯ Opioids, analgesic, knee pain, total knee replacement, knee surgery, pre-operative opioids, knee outcomes.

Epidermal keratinocytes play a vital role in restoration of the intact skin barrier during wound healing. The negative effect of hyperglycemia may prolong the wound healing process. Epidermal keratinocytes have been demonstrated to modulate and directly initiate nociceptive responses in rat models of fractures and chemotherapy-induced neuropathic pain. ⋯ Moreover, plantar incision induced the keratinocytes proliferation and expression of IL-1β and TNF-α in keratinocytes in both C57BL/6J mice and KK mice. Interestingly, compared to C57BL/6J mice, the slower and more persistent proliferation of keratinocytes and expression of IL-1β and TNF-α in keratinocytes were observed in KK mice. Together, our study suggested that plantar incision may induce the differential keratinocytes proliferation and expression of IL-1β and TNF-α in kertinocytes in diabetic and nondiabetic animals, which might be associated with the development and maintenance differences in diabetic and nondiabetic postoperative pain.

Electrochemotherapy (ECT) is a symptom control method for inoperable or exulcerating cutaneous metastases or skin cancer. With the help of electroporation, an enhancement of the efficacy of the administered chemotherapeutic agent, bleomycin or cisplatin, is achieved, which leads to a local reduction of the metastases and thereby has a low impact on the systemic health. ECT can be performed under local, regional or general anaesthesia, whereby the form of anaesthesia depends on the number and extent of the metastases as well as the affected body site. ⋯ To prevent lung damage from bleomycin, the patient has to be ventilated with a low FiO2 (< 0.3), or preferably with room air. To avoid drug interactions and postoperative pain, general anaesthesia is performed as TIVA in deep relaxation. The anaesthesia team should be aware of the necessary precautions when applying chemotherapeutic agents and should recognize contraindications to performing anaesthesia in ECT in advance.

Randomized Controlled TrialThe effects of early femoral nerve block intervention on preoperative pain management and incidence of postoperative delirium geriatric patients undergoing trochanteric femur fracture surgery: A randomized controlled trial.
Hip fracture is a common clinical problem which causes severe pain in geriatric patients. However, severe pain following fracture may bring on mental disorders and delirium. A neuroinflammatory response with IL-6 and IL-8 has been shown to be associated with the pathophysiology of delirium. In this study, our primary hypothesis is that preoperative femoral nerve block (FNB) intervention in geriatric patients will more effectively attenuate pain following trochanteric femur fracture than the preoperative paracetamol application. Our secondary hypothesis is that interleukin levels (IL-6, IL-8) in cerebrospinal fluid (CSF) will be lower in the femoral nerve block group than the paracetamol group. Our tertiary hypothesis is that the incidence of postoperative delirium will be lower in the femoral nerve block group. ⋯ The femoral nerve block was more effective in preoperative pain management of trochanteric femur fracture and preventing pain during regional anesthesia application. The mean IL-8 level was lower in the femoral nerve block group when compared to the paracetamol group. There is no difference in the postoperative delirium incidence between groups.

The study aimed at investigating the effect of local infiltration analgesia (LIA) with ropivacaine on postoperative analgesia for patients undergoing ankle fracture surgery. ⋯ The retrospective cohort study indicates that LIA with ropivacaine can provide better early postoperative pain management with a reduction of VAS scores for ankle fracture surgery. Patients receiving wound infiltration also experience decreased opioid consumption, a lower rate of analgesia-related side effects, and comparable wound complication rate.
