Abstract Background Pain is a nearly universal experience, but little is known about how people treat pain. This international survey assessed real-world pain management strategies. Methods From 13-31 January, 2020, an online survey funded by GSK Consumer Healthcare was conducted in local languages in Australia, Brazil, Canada, China, Colombia, France, Germany, India, Italy, Japan, Saudi Arabia, Malaysia, Mexico, Poland, Russia, Spain, Sweden, UK, and USA. Adults were recruited from online panels of people who agreed to participate in surveys. Quotas ensured nationally representative online populations based on age, gender, and region. Results Of 19,000 people (1000/country) who completed the survey, 18,602 (98%) had ever experienced physical pain; 76% said they would like to control their pain better. Presented with 17 pain-management strategies and asked to select the ones they use in the order of use, respondents chose an average of 4 strategies each. The most commonly selected strategies were pain medication (65%), rest/sleep (54%), consult a doctor (31%), physical therapy (31%), and nonpharmacologic action (eg, heat/cold application; 29%). Of those who use pain medication, 56% take some other action first. Only 36% of those who treat pain do so immediately; 56% first wait to see if it will resolve spontaneously. Top reasons for waiting include a desire to avoid medication (37%); willingness to tolerate less severe pain (33%); concerns about side effects (21%) or dependency (21%); and wanting to avoid a doctor's visit unless pain is severe or persistent (21%). Nearly half (42%) of those who take action to control pain have visited ≥1 healthcare professional (doctor 31%; pharmacist 18%; other 17%) about pain. Conclusions This large global survey shows that people employ a range of strategies to manage pain but still wish for better pain control. Although pain medication is the most commonly used strategy, many people postpone or avoid its use. Key messages More than three-quarters (76%) of respondents across countries seek better pain control. Pain medication and rest/sleep consultation are the most common pain management strategies. More than half of respondents (56%) wait to see if pain will resolve spontaneously before taking any action, and 56% of those who use pain medication try some other approach first.

Pain is a traumatic experience and discomfort for all patients, especially critically ill patients; if not treated properly, it can have harmful effects. Critical illnesses are usually painful, both because of the underlying source of the disease and the necessary procedures performed to monitor and care for these patients. Pain induces anxiety, sleep deprivation, disorientation, agitation, delirium, and often become chronic depression. Psychological factors (sleep deprivation, anxiety, and delirium) can also increase the perception of pain. Pain assessment is required for proper pain management. Opioids are commonly used in pain management, but acetaminophen, dexmedetomidine, and gabapentin have more advantages. The recent trend is multimodal analgesia, which uses a combination of analgesic drugs with different mechanisms of action. Another trend is the increasing use of pain relievers, which can control pain and relieve anxiety.

PURPOSE: To evaluate the analgesic and neuroendocrine effects of electroanalgesia in dogs undergoing ovariohysterectomy. METHODS: Eighteen dogs were randomly distributed to three groups of six animals each and received either electrical stimuli at acupuncture points (EA), at peri-incisional dermatomes (DER) and at both acupuncture points and peri-incisional dermatomes (EAD). Pre-anesthetic medication was acepromazine (0.05mg kg-1, IV). Anesthesia was induced with propofol (4 to 5mg kg-1, IV) and maintained with isoflurane. Postoperatively pain degree was measured using a numerical rating scale. Dogs were scored at 1, 3, 6, 12 and 24 hours postoperative. If the pain score was ≥6, supplemental morphine (0.5mg kg-1, IM) was administered. Serum cortisol concentration was measured before pre-anesthetic medication (basal), and at 1, 12 and 24 hours postoperative. RESULTS: EA and EAD- treated dogs had lower pain scores than DER treated dogs one hour postoperatively. Fewer EA and EAD-treated dogs required rescue analgesia. Serum cortisol did not differ among treatments. CONCLUSION: Preoperative application of electrical stimuli to acupuncture points isolated or in combination with peri-incisional dermatomes provides a reduced postoperative opioid requirement and promotes an effective analgesia in dogs undergoing ovariohyterectomy.

ABSTRACT: Progressive deterioration and loss of articular cartilage are the final degenerative events common to osteoarthritis (OA). Reactive oxygen species (ROS) play an important role in this chondrocyte catabolic activity, leading to cell death and matrix components breakdown. Intra-articular corticosteroid injections such as triamcinolone acetonide have been used to control pain and inflammation associated with OA. New treatments for OA, platelet-rich plasma and pentosan polysulphate sodium have also been used and further investigations are necessary to determine their safety in joint cells. In this in vitro study, the use of these three substances (triamcinolone acetonide, platelet-rich plasma, and pentosan polysulphate sodium) in healthy chondrocytes did not alter the antioxidant status when compared to control groups, indicating that they could be considered safe in healthy conditions.
