Exposure to fine particulate matter in the week before surgery is associated with higher rates of pneumonia, sepsis, and surgical wound infections.<\/p>\n
RT\u2019s Three Key Takeaways:<\/p>\n
Preoperative Exposure Risk: Research involving nearly 50,000 patients found that elevated levels of fine particulate matter in the week before surgery increased the risk of major medical and infectious complications.<\/p>\n
Systemic Health Impact: Fine particulate matter can enter the smallest parts of the lung and cross into the bloodstream, causing systemic inflammation that stresses the heart and lungs.<\/p>\n
Quantifiable Risk Increase: When air pollution levels exceeded Environmental Protection Agency daily limits, the absolute risk of post-surgical complications rose from 4.8% to 6.2%.<\/p>\n
Preoperative exposure to high levels of air pollution<\/a> is associated with an increased risk of post-surgical complications, according to a study<\/a> published in Acta Anaesthesiologica Scandinavica. The research linked higher levels of fine particulate matter to a composite measure of complications that included pneumonia<\/a>, sepsis<\/a>, and surgical wound infections.<\/p>\n Researchers from University of Utah Health analyzed data from 49,615 non-emergency surgeries performed in the Wasatch Front region of Utah. By utilizing a combination of Environmental Protection Agency (EPA) sensors and satellite data, the team estimated air pollution levels at each patient\u2019s home address for the week prior to their procedure.<\/p>\n \u201cWhen there was an elevation in PM2.5 air pollution in the week before surgery, even for one day, we saw increased risk of major medical complications and infectious complications,\u201d said John Pearson, MD, first author on the paper and associate professor of anesthesiology at Stanford Medicine.<\/p>\n Impact of Fine Particulate Matter<\/p>\n The study focused on PM2.5, or fine particulate air pollution, due to its ability to cause systemic health effects. When air pollution levels exceeded the EPA daily exposure limit in the week before surgery, the risk of post-surgical complications increased from 4.8% to 6.2%. The researchers found that every 10ug\/m3 increase in PM2.5 was associated with approximately an 8% increase in the relative risk of complications.<\/p>\n \u201cParticles of that size or smaller can get down to the smallest part of the lung,\u201d said Nathan Pace, MD, professor of anesthesiology at University of Utah Health and a coauthor on the paper, in a news release. \u201cSome of it will cross into the blood and it can end up anywhere in your body: your brain, your heart, your liver, your kidneys.\u201d<\/p>\n This exposure increases overall levels of inflammation, putting significant stress on the lungs and heart, which may increase the risk of subsequent infections, according to the researchers.<\/p>\n Clinical Implications for Healthcare Providers<\/p>\n While the study found a clear association, the researchers noted that the observational nature of the work means it cannot determine if air pollution directly caused the complications or if an unknown third factor was involved.<\/p>\n \u201cA caveat in any observational study is that there might be a relevant factor that affects both the exposure and the outcome,\u201d said Pace.<\/p>\n The research team emphasized that further studies involving multiple healthcare centers are needed to determine which specific surgeries are most affected by air quality. Such data could eventually help healthcare facilities time elective surgeries to minimize risks during periods of poor air quality.<\/p>\n For now, the researchers suggested that standard precautions, such as using high-quality home air filters and avoiding outdoor exercise during high-pollution events, remain a healthy choice for all patients.<\/p>\n \u201cIt\u2019s always a good idea to protect your health during bad air pollution events,\u201d said Pearson.<\/p>\n","protected":false},"excerpt":{"rendered":"Exposure to fine particulate matter in the week before surgery is associated with higher rates of pneumonia, sepsis,…\n","protected":false},"author":2,"featured_media":430254,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[7765,30116,50983,163,85,46,76121,201798],"class_list":["post-430253","post","type-post","status-publish","format-standard","has-post-thumbnail","category-health","tag-air-pollution","tag-air-quality","tag-environmental-news","tag-health","tag-il","tag-israel","tag-surgery-and-postsurgical-care","tag-thoracic-surgery-and-lung-transplant"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/430253","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=430253"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/430253\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/430254"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=430253"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=430253"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=430253"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
