The opioid disaster stays a major public well being problem in america. In 2022, over 2.5 million American adults had an opioid use dysfunction, and opioids accounted for almost 76% of overdose deaths.
Some sufferers are terrified of utilizing opioids after surgical procedure because of issues about dependence and potential uncomfortable side effects, even when appropriately prescribed by a physician to handle ache. Surgical procedure is commonly the primary time sufferers obtain an opioid prescription, and their widespread use raises issues about sufferers turning into long-term customers. Leftover capsules from a affected person’s prescriptions may additionally be misused.
Researchers like us are working to develop a personalised and complete surgical expertise that doesn’t use opioids. Our strategy to opioid-free surgical procedure addresses each bodily and emotional well-being by way of efficient anesthesia and complementary pain-management methods.
What’s opioid-free anesthesia?
Clinicians have used morphine and different opioids to handle ache for hundreds of years. These medicine stay integral to anesthesia.
Most surgical procedures use a technique known as balanced anesthesia, which mixes medicine that induce sleep and chill out muscle tissue with opioids to manage ache. Nonetheless, utilizing opioids in anesthesia can result in undesirable uncomfortable side effects, corresponding to severe cardiac and respiratory issues, nausea and vomiting, and digestive points.
Issues over these antagonistic results and the opioid disaster have fueled the event of opioid-free anesthesia. This strategy makes use of non-opioid medicine to alleviate ache earlier than, throughout and after surgical procedure whereas minimizing the danger of uncomfortable side effects and dependency. Research have proven that opioid-free anesthesia can present related ranges of ache reduction to conventional strategies utilizing opioids.
Opioid-free anesthesia is presently based mostly on a multimodal strategy. This implies remedies are designed to focus on varied ache receptors past opioid receptors within the spinal wire. Multimodal analgesia makes use of a mixture of no less than two drugs or anesthetic methods, every relieving ache by way of distinct mechanisms. The purpose is to successfully block or modulate ache indicators from the mind, spinal wire and the nerves of the physique.
Balanced anesthesia combines a variety of completely different medicine to make sure a easy surgical procedure.

As an illustration, nonsteroidal anti-inflammatory medicine, or NSAIDs, corresponding to ibuprofen work by inhibiting COX enzymes that promote irritation. Acetaminophen, or Tylenol, equally inhibits COX enzymes. Whereas each acetaminophen and NSAIDs primarily goal ache on the surgical website, they’ll additionally exert results on the spinal degree after a number of days of use.
A category of medication known as gabapentinoids, which embrace gabapentin and pregabalin, goal sure proteins to dampen nerve sign transmission. This decreases neuropathic ache by lowering nerve irritation.
The anesthetic ketamine disrupts ache pathways that contribute to a situation known as central sensitization. This dysfunction happens when nerve cells within the spinal wire and mind amplify ache indicators even when the unique harm or supply of ache has healed. In consequence, regular sensations corresponding to mild contact or delicate strain could also be perceived as painful, and painful stimuli could really feel extra intense than normal. By lessening ache sensitivity, ketamine can assist cut back the danger of continual ache.
Regional anesthesia entails injecting native anesthetics close to nerves to dam ache indicators to the mind. This methodology permits sufferers to stay awake however pain-free within the numbed space, lowering the necessity for basic anesthesia and its uncomfortable side effects. Frequent regional methods embrace epidurals, spinal anesthesia and nerve blocks.
By activating completely different ache pathways concurrently, multimodal approaches purpose to reinforce ache reduction synergistically.
Psychology of ache notion
Psychological elements can considerably affect a affected person’s notion of ache. Analysis signifies that psychological well being circumstances corresponding to nervousness, melancholy and sleep disturbances can improve ache ranges by as much as 50%. This implies that addressing temper and sleep points may be important for ache administration and enhancing total affected person well-being.
Psychological states can intensify the notion of ache by considerably influencing the neural pathways associated to ache processing. For instance, nervousness and stress activate the physique’s battle or flight response, prompting the discharge of stress hormones that heighten nerve sensitivity. This could make ache really feel extra intense. Analysis has additionally discovered that increased nervousness ranges earlier than surgical procedure are linked to elevated anesthesia use throughout surgical procedure and opioid consumption after surgical procedure.
Addressing ache earlier than an operation could make sufferers really feel higher post-op.

Complementary and different methods that deal with psychological elements can cut back ache and opioid use by modulating ache transmission within the nervous system and activating neurochemical pathways that promote ache reduction.
For instance, aromatherapy makes use of important oils to stimulate the olfactory system. This can assist cut back ache notion and improve total well-being by evoking emotional responses and selling rest.
Music remedy stimulates the auditory system, which might distract sufferers from ache, decrease nervousness ranges and foster emotional therapeutic. This could finally result in lowered ache notion.

Partaking the parasympathetic system helps the physique preserve power, sluggish your coronary heart fee, decrease blood strain and relieve muscle stress. This could result in decreased ache sensitivity by selling a state of calmness.
Acupuncture entails inserting skinny needles into particular physique factors, stimulating the discharge of endorphins and different neurotransmitters. These molecules can interrupt ache indicators and promote therapeutic processes throughout the physique.
Transferring towards opioid-free surgical procedure
Transitioning away from opioids in surgical procedure requires a shift in each apply and mindset throughout the whole well being care workforce. Past anesthesiologists, different suppliers, together with surgeons, nurses and medical trainees, additionally use opioids in affected person care. All suppliers would must be open to utilizing different ache administration methods all through the surgical course of.
In response to the growing affected person demand for opioid-free surgical care, our workforce on the College of Pittsburgh Medical Heart launched the patient-initiated Opioid-Free Surgical Ache Administration Program in Could 2024. To handle each the bodily and emotional dimensions of ache whereas optimizing restoration and security, we recruited surgeons, anesthesiologists, nurses, pharmacists and hospital directors to take part within the initiative.
Over the course of six months, our workforce enrolled 109 sufferers, 79 of whom efficiently underwent surgical procedures with out opioids. Limitations to collaborating in this system included affected person notion of extreme ache, inadequately addressing stress and nervousness earlier than the operation and restricted training within the division about this system.
Nonetheless, subsequent refinements to this system – corresponding to giving sufferers muscle relaxants whereas they had been recovering from anesthesia – improved participation and lowered opioid use. Importantly, not one of the 19 sufferers who acquired opioids whereas recovering within the hospital post-op required additional opioid prescriptions at discharge.
These outcomes mirror the promise of our pathway to reduce reliance on opioids whereas making certain efficient ache administration. Enhanced psychological help for sufferers and training for suppliers in surgical procedure departments can broaden the effectiveness of a complete strategy to managing ache.
