In Zambia, there are no context appropriate standardised clinical guidelines for post-operative pain observations. This study sought to develop such a clinical guideline in form of an assessment tool. The study adopted an exploratory sequential mixed method through a three-phased approach and an adapted Clinical Decision Making Survey instrument was used. Snowball sampling was employed and in phases II and III, purposive sampling was used. The study was conducted at the University Teaching Hospitals where 120 participants were enrolled in the study. Phases II and III provided preliminary internal validation processes of the developed tool, where discussions, orientation and trial implementation of the tool were done. In phase II of the study, 47 participants comprising of nurses participated while in phase III, there were 11 nurses and 32 participants. The results yielded the first ever standardised post-operative pain assessment tool for patients with major abdominal surgery in Zambia. The tool is made up of six dimensions of the identified nonverbal indicators of post-operative pain in patients with major abdominal surgery namely: facial expressions, mobility, activity intolerance, behavioural disturbance, communication ability and vital signs. The present study showed that the developed post-operative pain assessment tool for Zambia is acceptable for use among patients who have had major abdominal surgery and can facilitate improved post-operative pain management for most patients.展开更多

In NMOSD pathology, damageassociated molecular patterns(DAMPs), including ATP, are released from damaged astrocytes, triggering the activation of innate immune cells. ATP is a central mediator of acute pain in NMOSD.展开更多

Methods: Eighty patients who underwent thoracoscopic surgery in a tertiary hospital were selected as the study subjects and randomly divided into two groups, with 40 patients in each group. The control group received routine postoperative treatment with intravenous pain pump, while the experimental group received Parecoxib in addition to the standard postoperative pain pump treatment. Visual Analog Scale (VAS) pain scores were used to evaluate postoperative pain relief in both groups, along with adverse reactions, postoperative complications, and patient satisfaction with pain relief. Results: Patients who received Parecoxib injection in addition to the routine use of intravenous pain pump had VAS pain scores lower than 3 points at 6 h, 12 h, 24 h, and 36 h postoperatively compared to those in the control group. The incidence of postoperative lung collapse, pleural effusion, and pulmonary infections was also significantly lower in the experimental group. The differences between the two groups were statistically significant (P Conclusion: Early combined use of Parecoxib injection in the early postoperative period after thoracoscopic surgery has shown good clinical efficacy. It can reduce the level of pain in patients, promote effective coughing and expectoration, facilitate early mobilization of patients, improve patient compliance, reduce complications, shorten hospital stay, and expedite patient recovery. Therefore, it is worth promoting the widespread clinical application of Parecoxib injection in this setting.展开更多

CRPS can be a debilitating condition with high levels of pain and reduced function. Aim: This case report aims to discuss the multimodal approach in the management of a patient who presented with ongoing poorly controlled pain secondary to CRPS from an injury that happened years prior. Case Presentation: A 45-year-old female was involved in a motor vehicle accident where her right leg was injured. She underwent several surgeries and developed CRPS that significantly reduced her mobility and quality of life. She presented to the pain clinic years after her initial injury and a multimodal regimen was started for her resulting in significantly improved function. Conclusion: CRPS can be a severely debilitating condition. While early diagnosis and management are important, ongoing management in the outpatient chronic pain setting is important in maintaining a good level of function.展开更多

文摘Objective Type A acute aortic dissection(TAAAD)is a dangerous and complicated condition with a high death rate before hospital treatment.Patients who are fortunate to receive prompt surgical treatment still face high in-hospital mortality.A series of post-operative complications further affects the prognosis.Post-operative pneumonia(POP)also leads to great morbidity and mortality.This study aimed to identify the prevalence as well as the risk factors for POP in TAAAD patients and offer references for clinical decisions to further improve the prognosis of patients who survived the surgical procedure.Methods The study enrolled 89 TAAAD patients who underwent surgical treatment in Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology,Wuhan,Hubei province,China from December 2020 to July 2021 and analyzed the perioperative data and outcomes of these patients.Logistic regression analyses were used to identify the risk factors for POP.Results In the study,31.5%of patients developed POP.Patients with POP had higher proportions of severe oxygenation damage,pneumothorax,reintubation,tracheotomy,renal replacement therapy,arrhythmia,gastrointestinal bleeding,and longer duration of mechanical ventilation,fever,ICU stay,and length of stay(all with P<0.05).The in-hospital mortality was 2.3%.Smoking,preoperative white blood cells,and intraoperative transfusion were the independent risk factors for POP in TAAAD.Conclusion Patients who underwent TAAAD surgery suffered poorer outcomes when they developed POP.Furthermore,patients with risk factors should be treated with caution.
文摘Background:Extended-release buprenorphine(XR)is indicated for pain management in rodents,but little is known about its use in mice.This study aimed to investigate whether high dose XR effectively attenuates post-operative hypersensitivity better than low dose XR in a mouse model of incisional pain.Methods:Mice(n 44)were randomly assigned to 1 of 4 treatment groups:(a)saline(1 ml/kg SC,once);(b)sustained release buprenorphine(Bup-SR,1 mg/kg SC,once);(c)low dose extended-release buprenorphine(XR-lo,3.25 mg/kg SC,once);(d)high dose extended-release buprenorphine(XR-hi,6.5 mg/kg SC,once).On days1,0(4 hours),1,2,and 3,mechanical and thermal hypersensitivities were evaluated,and plasma buprenorphine concentrations were measured.Results:Mechanical(days 0-2)and thermal(days 0-1)hypersensitivities were ob-served in the saline group.Bup-SR,XR-lo,and XR-hi attenuated mechanical hyper-sensitivity on days 0,1,and 2.None of the treatment groups,except XR-Lo on day 0,attenuated thermal hypersensitivity on days 0 or 1.Plasma buprenorphine concen-tration peaked at 4 hours(day 0)in all treatment groups and remained greater than 1 ng/mL on days 0-2.No abnormal clinical observations or gross pathologic findings were seen in any groups.Conclusion:The results indicate XR-hi did not effectively attenuate post-operative hypersensitivity better than XR-lo.Thus both 3.25 and 6.5 mg/kg XR are recom-mended for attenuating post-operative hypersensitivity for at least up to 48 hours in mice.
文摘BACKGROUND Trochanteric bursitis is a common complication following total hip replacement(THR),and it is associated with high level of disability and poor quality of life.Excision of the trochanteric bursa prophylactically during THR could reduce the occurrence of post-operative trochanteric bursitis.AIM To evaluate whether synchronous trochanteric bursectomy at the time of THR affects the incidence of post-operative trochanteric bursitis.METHODS This retrospective cohort study was conducted in the secondary care setting at a large district general hospital.Between January 2010 and December 2020,954 patients underwent elective primary THR by two contemporary arthroplasty surgeons,one excising the bursa and the other not(at the time of THR).All patients received the same post-operative rehabilitation and were followed up for 1 year.We reviewed all cases of trochanteric bursitis over this 11-year period to determine the incidence of post-THR bursitis.Two proportion Z-test was used to compare incidences of trochanteric bursitis between groups.RESULTS 554 patients underwent synchronous trochanteric bursectomy at the time of THR whereas 400 patients did not.A total of 5 patients(incidence 0.5%)developed trochanteric bursitis following THR;4 of whom had undergone bursectomy as part of their surgical approach,1 who had not.There was no statistically significant difference between the two groups(Z value 1.00,95%CI:-0.4%to 1.3%,P=0.32).There were also 8 other patients who had both trochanteric bursitis and hip osteoarthritis prior to their THR;all of whom were treated with THR and synchronous trochanteric bursectomy,and 7 had resolution of their lateral buttock pains but 1 did not.CONCLUSION Synchronous trochanteric bursectomy during THR does not materially affect the incidence of post-operative bursitis.However,it is successful at treating patients with known trochanteric bursitis and osteoarthritis requiring THR.

文摘In Quebec,Canada,the public healthcare system offers free medical services.However,patients with spinal pain often encounter long waiting times for specialist appointments and limited physiotherapy coverage.In contrast,private clinics provide expedited care but are relatively scarce and entail out-of-pocket expenses.Once a patient with pain caused by a spinal disorder meets a pain medicine specialist,spinal intervention is quickly performed when indicated,and patients are provided lifestyle advice.Transforaminal epidural steroid injections are frequently administered to patients with radicular pain,and steroid injections are administered on a facet joint to control low back or neck pain.Additionally,medial branch blocks are performed prior to thermocoagulation.France’s universal healthcare system ensures accessibility at controlled costs.It emphasizes physical activity and provides free physical therapy services.However,certain interventions,such as transforaminal and interlaminar epidural injections,are not routinely used in France owing to limited therapeutic efficacy and safety concerns.This underutilization may be a potential cause of chronic pain for many patients.By examining the differences,strengths,and weaknesses of these two systems,valuable insights can be gained for the enhancement of global spinal pain management strategies,ultimately leading to improved patient outcomes and satisfaction.
文摘Over the past two decades,the USA has witnessed a steep rise in the incidence of acute cholecystitis(AC),[1]even among children,[2]with over 200,000 cases annually.[3]Patients with AC often present to the emergency department(ED)experiencing severe distress,with most describing their pain level as“intolerable.”[4]Furthermore,there is usually a considerable delay before surgery,with a median time from diagnosis of AC to surgery of 28.5 h,[5]and a substantial percentage of patients wait as long as 10 d.[6]Prolonged delays before surgery lead to increased opioid use,which is associated with extended hospital stays and higher rates of readmission after cholecystectomy.[7]Furthermore,opioids can lead to vomiting,respiratory depression,delirium,and ultimately addiction.[8]We propose a novel regional anesthesia technique for managing AC:right phrenic nerve blockade.This method could offer improved pain control and a more favorable risk profile in selected patients when compared to current ED practices.

文摘In this editorial we comment on the article published in a recent issue of the World Journal of Clinical Cases.This article described a novel ultrasound-guided lateral recess block approach in treating a patient with lateral recess stenosis.The impact of spinal pain-related disability extends significantly,causing substantial human suffering and medical costs.Each county has its preferred treatment strategies for spinal pain.Here,we explore the lower back pain(LBP)treatment algorithm recommended in France.The treatment algorithm for LBP recommended by the French National Authority for Health emphasizes early patient activity and minimal medication use.It encourages the continuation of daily activities,limits excessive medication and spinal injections,and incorporates psychological assessments and non-pharmacological therapies for chronic cases.However,the algorithm may not aggressively address acute pain in the early stages,potentially delaying relief and increasing the risk of chronicity.Additionally,the recommended infiltrations primarily involve caudal epidural steroid injections,with limited consideration for other injection procedures,such as transforaminal or interlaminar epidural steroid injections.The fixed follow-up timeline may not accommodate patients who do not respond to initial treatment or experience intense pain,potentially delaying the exploration of alternative therapies.Despite these limitations,understanding the strengths and weaknesses of the French approach could inform adaptations in LBP treatment strategies globally,potentially enhancing patient outcomes and satisfaction across diverse healthcare systems.
文摘In this article, we present our previous research, which highlighted adenosine triphosphate(ATP) as the cause of neuropathic pain during the acute phase of neuromyelitis optica spectrum disorder(NMOSD). In NMOSD pathology, damageassociated molecular patterns(DAMPs), including ATP, are released from damaged astrocytes, triggering the activation of innate immune cells. ATP is a central mediator of acute pain in NMOSD.
文摘In pat i e nt s,a s well as in animal mod e l s,hypersensitivity to external stimuli(hyperalgesia and allodynia)or spontaneous pain is often the first,and the most disabling,symptom of neuropathy(Davis et al.,2020).The increased activity of sensitive neurons drives pain development,making ion channel modulation a fundamental target for current pharmacotherapy as well as one of the most investigated by the R&D departments of pharmaceutical companies(Bennett et al.,2019).

文摘Bone is a mechanosensitive tissue and undergoes constant remodeling to adapt to the mechanical loading environment.However,it is unclear whether the signals of bone cells in response to mechanical stress are processed and interpreted in the brain.In this study,we found that the hypothalamus of the brain regulates bone remodeling and structure by perceiving bone prostaglandin E2(PGE2)concentration in response to mechanical loading.Bone PGE2 levels are in proportion to their weight bearing.When weight bearing changes in the tail-suspension mice,the PGE2 concentrations in bones change in line with their weight bearing changes.Deletion of cyclooxygenase-2(COX2)in the osteoblast lineage cells or knockout of receptor 4(EP4)in sensory nerve blunts bone formation in response to mechanical loading.Moreover,knockout of TrkA in sensory nerve also significantly reduces mechanical load-induced bone formation.Moreover,mechanical loading induces cAMP-response element binding protein(CREB)phosphorylation in the hypothalamic arcuate nucleus(ARC)to inhibit sympathetic tyrosine hydroxylase(TH)expression in the paraventricular nucleus(PVN)for osteogenesis.Finally,we show that elevated PGE2 is associated with ankle osteoarthritis(AOA)and pain.Together,our data demonstrate that in response to mechanical loading,skeletal interoception occurs in the form of hypothalamic processing of PGE2-driven peripheral signaling to maintain physiologic bone homeostasis,while chronically elevated PGE2 can be sensed as pain during AOA and implication of potential treatment.
文摘Objective: To explore the clinical effectiveness of combined use of intravenous pain pump with Parecoxib injection in alleviating pain in patients during the early postoperative period after thoracoscopic surgery. Methods: Eighty patients who underwent thoracoscopic surgery in a tertiary hospital were selected as the study subjects and randomly divided into two groups, with 40 patients in each group. The control group received routine postoperative treatment with intravenous pain pump, while the experimental group received Parecoxib in addition to the standard postoperative pain pump treatment. Visual Analog Scale (VAS) pain scores were used to evaluate postoperative pain relief in both groups, along with adverse reactions, postoperative complications, and patient satisfaction with pain relief. Results: Patients who received Parecoxib injection in addition to the routine use of intravenous pain pump had VAS pain scores lower than 3 points at 6 h, 12 h, 24 h, and 36 h postoperatively compared to those in the control group. The incidence of postoperative lung collapse, pleural effusion, and pulmonary infections was also significantly lower in the experimental group. The differences between the two groups were statistically significant (P Conclusion: Early combined use of Parecoxib injection in the early postoperative period after thoracoscopic surgery has shown good clinical efficacy. It can reduce the level of pain in patients, promote effective coughing and expectoration, facilitate early mobilization of patients, improve patient compliance, reduce complications, shorten hospital stay, and expedite patient recovery. Therefore, it is worth promoting the widespread clinical application of Parecoxib injection in this setting.
文摘BACKGROUND:To describe trends in oxycodone and oxycodone-containing analgesic prescribing for the treatment of back pain among adults in emergency departments(EDs) in the USA from 2007 to 2018.METHODS:Data were gathered from the National Hospital Ambulatory Medical Care Survey(NHAMCS) from 2007 to 2018.The study population included individuals of all ages presenting to USA EDs.The NHAMCS reasons for visit and oxycodone drug ID codes were used to isolate patients with back pain.The main outcome was the proportion of oxycodone and oxycodone-containing analgesics prescribed for back pain in the EDs over the specified time period.RESULTS:There was a relative decrease in the overall administration of oxycodone for back pain in the EDs by 62.3% from 2007(244,000 visits) to 2018(92,000 visits).The proportion of ED patients prescribed with oxycodone-containing analgesics for back pain increased among patients aged 45 years and older(from 43.8% to 57.6%),female patients(from 54.5% to 62.0%),black patients(from 22.5% to 30.4%),and Hispanic/Latino patients(from 9.4% to 19.6%).Oxycodone/acetaminophen was most prescribed and accounted for 90.2% of all oxycodone-containing analgesics in 2007,with a decrease to 68.5% in 2018.Pure oxycodone was the second most prescribed medication,accounting for 6.1% in 2007 and 31.5% in 2018.CONCLUSION:The overall number of oxycodone-containing analgesics decreased significantly from 2007 to 2018.However,that number trended upward in 45-year-old and older,female,black,or Hispanic/Latino patients from 2007 to 2018.The total amount of pure oxycodone increased significantly from 2007 to 2008.
文摘Background: Complex Regional Pain Syndrome (CRPS), previously known as reflex sympathetic dystrophy and causalgia, is a neuropathic pain condition that usually develops after an injury to an extremity. CRPS can be a debilitating condition with high levels of pain and reduced function. Aim: This case report aims to discuss the multimodal approach in the management of a patient who presented with ongoing poorly controlled pain secondary to CRPS from an injury that happened years prior. Case Presentation: A 45-year-old female was involved in a motor vehicle accident where her right leg was injured. She underwent several surgeries and developed CRPS that significantly reduced her mobility and quality of life. She presented to the pain clinic years after her initial injury and a multimodal regimen was started for her resulting in significantly improved function. Conclusion: CRPS can be a severely debilitating condition. While early diagnosis and management are important, ongoing management in the outpatient chronic pain setting is important in maintaining a good level of function.
