The opioid disaster stays a major public well being problem in the USA. In 2022, over 2.5 million American adults had an opioid use dysfunction, and opioids accounted for practically 76% of overdose deaths.
Some sufferers are afraid of utilizing opioids after surgical procedure because of considerations about dependence and potential unwanted effects, even when appropriately prescribed by a health care provider to handle ache. Surgical procedure is usually the primary time sufferers obtain an opioid prescription, and their widespread use raises considerations about sufferers changing into long-term customers. Leftover tablets from a affected person’s prescriptions might also be misused.
Researchers like us are working to develop a personalised and complete surgical expertise that doesn’t use opioids. Our method to opioid-free surgical procedure addresses each bodily and emotional well-being by means of efficient anesthesia and complementary pain-management strategies.
What’s opioid-free anesthesia?
Clinicians have used morphine and different opioids to handle ache for 1000’s of years. These medication stay integral to anesthesia.
Most surgical procedures use a method referred to as balanced anesthesia, which mixes medication that induce sleep and chill out muscle mass with opioids to manage ache. Nevertheless, utilizing opioids in anesthesia can result in undesirable unwanted effects, comparable to critical cardiac and respiratory issues, nausea and vomiting, and digestive points.
Issues over these adversarial results and the opioid disaster have fueled the event of opioid-free anesthesia. This method makes use of non-opioid medication to alleviate ache earlier than, throughout and after surgical procedure whereas minimizing the chance of unwanted effects and dependency. Research have proven that opioid-free anesthesia can present comparable ranges of ache reduction to conventional strategies utilizing opioids.
Opioid-free anesthesia is at the moment based mostly on a multimodal method. This implies therapies are designed to focus on numerous ache receptors past opioid receptors within the spinal twine. Multimodal analgesia makes use of a mix of at the very least two drugs or anesthetic strategies, every relieving ache by means of distinct mechanisms. The goal is to successfully block or modulate ache alerts from the mind, spinal twine and the nerves of the physique.
Balanced anesthesia combines a variety of completely different medication to make sure a easy surgical procedure.

As an example, nonsteroidal anti-inflammatory medication, or NSAIDs, comparable 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 web site, they’ll additionally exert results on the spinal stage after a number of days of use.
A category of medication referred to as gabapentinoids, which embody gabapentin and pregabalin, goal sure proteins to dampen nerve sign transmission. This decreases neuropathic ache by decreasing nerve irritation.
The anesthetic ketamine disrupts ache pathways that contribute to a situation referred to as central sensitization. This dysfunction happens when nerve cells within the spinal twine and mind amplify ache alerts even when the unique harm or supply of ache has healed. Consequently, regular sensations comparable to mild contact or delicate strain could also be perceived as painful, and painful stimuli might really feel extra intense than standard. By lessening ache sensitivity, ketamine may help cut back the chance of persistent ache.
Regional anesthesia entails injecting native anesthetics close to nerves to dam ache alerts to the mind. This technique permits sufferers to stay awake however pain-free within the numbed space, decreasing the necessity for basic anesthesia and its unwanted effects. Frequent regional strategies embody epidurals, spinal anesthesia and nerve blocks.
By activating completely different ache pathways concurrently, multimodal approaches goal 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 situations comparable to anxiousness, despair and sleep disturbances can enhance ache ranges by as much as 50%. This means that addressing temper and sleep points may be important for ache administration and enhancing general affected person well-being.
Psychological states can intensify the notion of ache by considerably influencing the neural pathways associated to ache processing. For instance, anxiousness and stress activate the physique’s combat 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 larger anxiousness 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 strategies that tackle 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 may help cut back ache notion and improve general well-being by evoking emotional responses and selling leisure.
Music remedy stimulates the auditory system, which may distract sufferers from ache, decrease anxiousness ranges and foster emotional therapeutic. This could in the end result in decreased ache notion.
Rest workout routines, comparable to deep respiration and progressive muscle leisure, activate the parasympathetic nervous system and assist promote a state of relaxation. Participating the parasympathetic system helps the physique preserve vitality, gradual 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 alerts and promote therapeutic processes inside the physique.
Shifting towards opioid-free surgical procedure
Transitioning away from opioids in surgical procedure requires a shift in each observe and mindset throughout the complete well being care group. Past anesthesiologists, different suppliers, together with surgeons, nurses and medical trainees, additionally use opioids in affected person care. All suppliers would should be open to utilizing different ache administration strategies all through the surgical course of.
In response to the rising affected person demand for opioid-free surgical care, our group on the College of Pittsburgh Medical Heart launched the patient-initiated Opioid-Free Surgical Ache Administration Program in Might 2024. To deal with 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 group enrolled 109 sufferers, 79 of whom efficiently underwent surgical procedures with out opioids. Obstacles to collaborating in this system included affected person notion of extreme ache, inadequately addressing stress and anxiousness earlier than the operation and restricted schooling within the division about this system.
Nevertheless, subsequent refinements to this system – comparable to giving sufferers muscle relaxants whereas they have been recovering from anesthesia – improved participation and decreased 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 replicate the promise of our pathway to reduce reliance on opioids whereas making certain efficient ache administration. Enhanced psychological help for sufferers and schooling for suppliers in surgical procedure departments can broaden the effectiveness of a complete method to managing ache.
