The crisis of prescription opioid overuse and abuse has affected countries around the world, and anesthesiologists are well-positioned to make positive changes (1). Even minor outpatient surgical procedures, and their associated anesthesia and analgesia techniques, can lead to long-term opioid use (2,3). Patients who present for surgery with an active opioid prescription are very likely to still be on opioids after a year (4).
Anesthesiologists have been working to set up regional anesthesiology and acute pain medicine programs with careful coordination of inpatient and outpatient pain management to improve patient outcomes. Regional anesthesia, especially with continuous peripheral nerve block (CPNB) techniques, has been shown repeatedly to reduce patients’ need for opioid analgesia (5).
Today, the crisis of drug shortages threatens to reverse the many advances in perioperative pain control that have been achieved. https://dmhs.ca/uncategorized/8qua45zqd4 Local anesthetics or “numbing medications” represent a class of drugs that is our strongest weapon against opioids. These drugs (e.g., bupivacaine, lidocaine, ropivacaine) are currently in shortage. Targeted injections of local anesthetic in the form of regional anesthesia eliminate sensation at the site of surgery and can obviate the need for injectable opioids (e.g., fentanyl, hydromorphone, morphine) which also happen to be in short supply. Local anesthetics are also the critical ingredient in providing epidural pain relief and spinal anesthesia for childbirth. Without them, new moms will miss the first moments of their babies’ lives.
The following are potential ramifications of the current drug shortages affecting anesthesia and pain management on patient care:

Regional anesthesia techniques, which include spinal, epidural, and peripheral nerve blocks, offer patients many potential advantages in the perioperative and peripartum period. Human studies have demonstrated the following benefits: decreased pain, nausea and vomiting, and time spent in the recovery room (6,7). Long-acting local anesthetics (e.g., bupivacaine, levobupivacaine, and ropivacaine) generally provide analgesia of similar duration for 24 hours or less (8-11). These clinical effects of nerve blocks typically last long enough for patients to meet discharge eligibility from recovery and avoid unnecessary hospitalization for pain control (12). CPNB techniques (also known as perineural catheters) permit delivery of local anesthetic solutions to the site of a peripheral nerve on an ongoing basis (13). Portable infusion devices can deliver a solution of plain local anesthetic for days after surgery, often with the ability to titrate the dose up and down or even stop the infusion temporarily when patients feel too numb (14,15). In a meta-analysis comparing CPNB to single-injection peripheral nerve blocks in humans, CPNB results in lower patient-reported worst pain scores and pain scores at rest on postoperative day (POD) 0, 1, and 2 (16). Patients who receive CPNB also experience less nausea, consume less opioids, sleep better, and are more satisfied with pain management (16). By using local anesthetic medication to interrupt nerve transmission along peripheral nerves, patients continue to experience decreased sensation as long as the infusion is running. A shortage of local anesthetic medications makes it impossible for anesthesiologists to provide this potent form of opioid-sparing pain control for all surgical patients. This also means that local anesthetics cannot be administered by surgeons as wound infiltration to help patients with incisional pain, and epidural analgesia for laboring women may not be universally available.
Buying Zolpidem Increased Incidence of Postoperative Complications
Based on the study by Memtsoudis and colleagues, overall 30-day mortality for total knee arthroplasty patients is lower for patients who receive regional anesthesia, either neuraxial and combined neuraxial-general anesthesia, compared to general anesthesia alone (17). In most categories, the rates of occurrence of in-hospital complications (e.g. all-cause infections, pulmonary, cardiovascular, acute renal failure) are also lower for the neuraxial and combined neuraxial-general anesthesia groups vs. the general anesthesia only group, and transfusion requirements are lowest for neuraxial anesthesia patients compared to all other groups (17). The inability to offer regional anesthesia (e.g., spinal or epidural) to all patients due to lack of local anesthetics therefore represents a threat to patient safety.

Chronic pain may develop after many common operations including breast surgery, cesarean delivery, hernia repair, thoracic surgery, and amputation and is associated with severe acute pain in the postoperative period (18). A Cochrane systematic review and meta-analysis reviewed published studies on this subject, and the results favor epidural analgesia for prevention of persistent postsurgical pain (PPSP) after thoracotomy and favor paravertebral block for prevention of PPSP after breast cancer surgery at 6 months (19). Only regional blockade with local anesthetics can block patients’ sensation during and after surgery. Without local anesthetics for nerve blocks, spinals, and epidurals, patients will experience greater than expected acute pain, require additional opioid treatment, and potentially be at higher risk of developing chronic pain.

Approximately 31% of costs related to inpatient perioperative care is attributable to the ward admission (20). Anesthesiologists as perioperative physicians have an opportunity to influence the cost of surgical care by decreasing hospital length of stay through effective pain management and by developing coordinated multi-disciplinary clinical pathways (21,22). Regional anesthesia and analgesia can improve outcomes through integration into clinical pathways that involve a multipronged approach to streamlining surgical care (23,24). Inadequate pain control can delay rehabilitation, prolong hospital admissions, increase the rate of readmissions (25), and increase the costs of hospitalization for surgical patients.
In summary, regional anesthesia and analgesia has been shown in multiple studies to improve outcomes for obstetric and surgical patients. The current shortage of local anesthetics and other analgesic medications negatively affects quality of care and pain management and is a threat to patient safety.
