Rapid Review Quiz: Postoperative Pain Management
Postoperative pain remains a significant concern for surgical patients, with implications that extend beyond immediate discomfort and influence recovery trajectories, patient satisfaction, and long-term outcomes. Effective pain control is not just a matter of comfort — it's a clinical imperative. Yet, this goal must be pursued judiciously, as the overreliance on opioids carries well-documented risks of adverse effects and dependence. The landscape of pain management is evolving. While pharmacologic strategies such as opioids, nonsteroidal anti-inflammatory drugs, n-methyl-d-aspartate (NMDA) receptor antagonists, and regional anesthesia continue to play pivotal roles, their limitations have catalyzed a shift toward a more integrative, multimodal approach. Emerging evidence supports the use of non-pharmacological interventions — ranging from preoperative patient education to mind-body techniques and physical therapy — as effective complements that can reduce pain intensity, curb opioid use, and enhance functional recovery.
Recent clinical guideline updates for managing postoperative pain emphasize increased use of non-opioid treatments and multimodal strategies. This reflects growing recognition that while opioids are effective, they pose risks such as dependence and adverse side effects. Nonpharmacological and non-opioid interventions such as nonsteroidal anti-inflammatory drugs, NMDA receptor antagonists like ketamine, peripheral nerve blocks, and techniques like transcutaneous electrical nerve stimulation have been shown to reduce opioid use, improve pain control, and enhance recovery outcomes, especially when healthcare professionals are adequately trained to apply them. Randomized controlled trials support the efficacy of peripheral nerve stimulation for postsurgical pain, and evidence for this and other novel therapies continues to grow. Even patient factors such as sleep quality and the timing of surgery can significantly impact post-operative pain.
Programmed intermittent epidural bolus injection was shown to be more effective than other methods in improving both nighttime pain management and sleep quality in post-thoracotomy patients. Oral opioid analgesics can manage pain, but they often cause side effects like nausea, sedation, and sleep disruption, which can worsen postoperative recovery. General anesthesia is used during surgery but has no role in managing postoperative pain or improving sleep afterward. It does not contribute to nighttime pain relief once the patient is in recovery.

For a patient requiring a minimal hospital stay and quick postoperative recovery, single-injection nerve blocks are often the preferred pain management strategy. These blocks provide effective, targeted pain relief with a rapid onset and are simple to administer, making them ideal for shorter or less complex surgical procedures. Their use has been associated with reduced opioid consumption, quicker mobilization, and high patient satisfaction — factors critical for fast recovery and early discharge. The major limitation to single-injection nerve blocks is the duration of analgesia, typically lasting less than 24 hours. Peripheral nerve blocks and neuraxial blocks are a few types of single-injection nerve blocks commonly used. Continuous catheter techniques are more invasive, require careful monitoring, and carry risks such as infection, catheter displacement, or pump malfunction. These factors can delay discharge and complicate recovery, making them less ideal for rapid recovery cases. Oral analgesics may not provide adequate pain control on their own, especially immediately after surgery. Insufficient pain management can hinder mobility and prolong hospital stay. Multiple-injection nerve blocks are not usually used, instead single-injection nerve blocks are recommended for quick postoperative recovery.

A primary benefit of continuous catheter techniques over single-injection nerve blocks for postoperative pain management is that they offer prolonged analgesia, which enhances patient comfort and reduces the need for additional analgesics. Unlike single-injection blocks that wear off within hours, continuous catheter methods — such as continuous peripheral nerve blocks or epidural analgesia — provide sustained pain relief for 2-3 days. This extended duration allows for better pain control, supports early mobilization, and lowers reliance on opioids, ultimately improving recovery outcomes and patient satisfaction. Catheter techniques actually require more monitoring due to risks like infection, catheter displacement, or pump malfunction. Continuous nerve catheters can be used in ambulatory surgery with the evolution of local anesthetic delivery systems and pumps and even in outpatient procedures. While effective, continuous catheter techniques may carry higher complication risks related to catheter management, such as infections or technical failures. Thus, their key advantage lies in providing extended, consistent pain control for patients with significant postoperative pain needs.

Nondrug pain management encompasses a range of physical, psychological, and sensory interventions that provide effective, low-risk alternatives to medications. Although effectiveness varies between individuals, TENS can provide pain relief, is noninvasive, and cost-effective. Heat therapy can also relieve muscle tension and pain and improve blood flow, but it can cause burns if used improperly. Cryotherapy can also reduce pain and inflammation, although it can sometimes impair healing and is not suitable for everyone. Cryotherapy can limit blood flow, reduce the delivery of healing agents to the affected area, and cause tissue necrosis or nerve impairment. Individual responses to aromatherapy vary widely, and clinical evidence supporting its effectiveness remains limited.

Real Life Simulations: Mass Casualty Training in Med School
Anyone who watched television show The Pitt on Max knows how overwhelming a mass casualty event can be for a hospital. Preparation is key, and accredited hospitals are required to hold training exercises. But these incidents don't only affect physicians in the Emergency Department. The random nature of mass shootings, natural disasters, multi-car pileups, building collapses, and the like means an all-hands-on-deck situation could happen at any time. An increasing number of medical schools see the value in preparing their students early. 'Unfortunately this is where the world is going. We need to rely on ourselves because help may not be coming,' said Jeffrey Pearl, MD, associate dean of professional health education at the University of Texas (UT) at Tyler School of Medicine. 'In the end, the first line is going to be one of us picking someone out of the rubble from a tornado and putting a tourniquet on.' Unfortunately this is where the world is going. We need to rely on ourselves because help may not be coming. More than 20 years ago, the Associations of American Medical Colleges and the CDC issued a joint report recommending disaster-related training for medical students. It's still a relatively rare offering — by 2021, only seven allopathic medical schools in the US mentioned disaster response training in their course catalogs. But just 2 years later, that number had more than doubled. Roughly 10% of allopathic medical schools now offer it, as do a number of osteopathic medical schools. 'I think the best part is, it gives you perspective as to what goes on out in the field,' said Joshua Goodman, a rising fourth-year medical student at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell in Hempstead, New York. He's participated in the school's annual training day more than once. 'Even in non-MCI situations, you might wonder why the patient is being brought in in this condition. Why didn't they do this? Why didn't they do that? This gives you a better understanding of what it's really like out there, so you know what to expect and can act on it.' Different Approaches to the Same Concept In order to prepare their students for an unpredictable future, medical schools take a variety of tacks. At some schools, all students undergo this training. At others, it's voluntary. Scenarios include bus bombings, school shootings, landslides, and the like. Often, they're location-specific, like the New York City subway car used in Hofstra's training, done at the local fire training academy. 'They fill it with smoke, and have students come in to rescue patients,' said Thomas Kwiatkowski, MD, assistant dean for simulation and professor of emergency medicine and science education at Hofstra. 'Some victims speak a different language, which is typical for New York City. It really challenges the students.' The variations don't stop there: At both UT Tyler and Hofstra, all first-year medical students complete a full emergency medical technician course. It concludes with a mass casualty simulation, which provides the chance to really practice the skills they've just learned. 'We didn't just want them to ride along in an ambulance,' Kwiatkowski said. 'That's not going to provide anything more than observation. I wanted a true clinical experience.' A presentation on FEMA's National Incident Management System kicks off the day at Ohio University Heritage College of Osteopathic Medicine, Dublin, Ohio. Students then move on to training with emergency equipment like cervical collars and backboards. But the bulk of the day is spent at the local fire department's training center for a hands-on simulation. Training at Perelman School of Medicine, University of Pennsylvania, Philadelphia, is part of a popular 2-week elective in wilderness and disaster medicine. Medical students learn to handle scenarios including avalanches, dirty bombs, and chemical weapons. At Idaho College of Osteopathic Medicine, Meridian, Idaho, training has included a simulated music festival gone awry as well as a multi-vehicle accident. College of Osteopathic Medicine, University of New England, Portland, Maine, has held four annual mock events. Last year's program focused on the lessons learned in the 2023 mass shooting in nearby Lewiston. Investing in Realism Limited research has been done to show exactly how realistic simulations should be, but there is some that suggests the more accurately a scenario reflects real life, the more students can benefit from it. Depending on a medical school's budget, things can get quite realistic, indeed. For many, it includes going off-site to a training ground, where students must triage realistic victims even as they experience the chaos of an actual event. 'When they walk into a burn tower knowing that there's been an explosion, and they hear people screaming out and they can't see much, it's an environment that probably causes their heart rate to go up a little bit, perhaps their respiratory rate to go up a little bit,' said William Burke, DO, dean of Heritage College of Osteopathic Medicine, Ohio University, Athens, Ohio. 'I think those types of situations help you better understand, as an individual, how you might respond in real life.' William Burke, DO For the simulations' victims, most schools use a combination of mannequins and volunteers — either locals or other medical students. Often, moulage artists are brought in to apply special-effects makeup. At UT Tyler, a relatively new school, Pearl had a sizable budget to design the mass casualty training program. Faculty works with campus and local law enforcement, fire department and emergency medical services, and even the Federal Bureau of Investigation to make the event feel as real as possible for students. High-tech wound simulation includes three-dimensional printed shrapnel mounted on silicone patches that are easily applied to volunteers' bodies; bleeding systems that pump fake blood; two cut suits of repairable skin with organs that bleed — which can be operated on while actors wear them; and several mannequins with realistic injuries. A significant amount of effort goes into creating thoughtful, plausible scenarios. A school shooting is part of the simulation at Hofstra. 'The way they set it up is hyper realistic, in that you have real police officers acting, there's a lot of yelling, it's dark, there's a lot of banging on doors. It's frankly a little bit scary,' Goodman, the medical student, said. 'You really do feel like you're in a school and you have to hide but you also have to triage: Who can we get out? How are we going to get them out? Is it safe to open the door?' Decisions Under Pressure Whatever the scenario, the goal in all these simulations is the same: To help medical students learn to make life-or-death decisions quickly, under extreme circumstances. 'The first minute or two, they're a little shell shocked. After that, it's like watching your children grow up,' Pearl said. 'These are first- and second-year med students, and they're rocking and rolling.' Thomas Kwiatkowski, MD During the exercises, they must triage victims into color-coded categories. Yes, just like in The Pitt : Green goes to the walking wounded, those who need minimal help. Yellow indicates a more serious injury, but not immediately life-threatening. Red means a victim has severe injuries, but with a high potential for survival. Victims designated with a black mark are either deceased or have injuries incompatible with life. 'It's very difficult when you have to make that decision,' Kwiatkowski said. 'There are a couple of maneuvers that people do before they can decide to make someone black, but sometimes you can have someone who's talking to you, and you know that you can't save them. That's an important experience for students.' Other ethical considerations also play out. During some simulations, for instance, a school shooter is still active. Students must decide how to help children while staying safe themselves, or if and when it's worth it to risk their own lives. At Ohio University, one situation involves a bombing. Unbeknownst to the students, the bomber is among the victims. 'Students are turning victims over and see the person playing the bomber has another bomb underneath them,' Burke said. 'It helps them understand the ethics of the situation: Do you treat them the same? The answer is yes, you take care of everybody. When you ask those questions, students are thinking about things in ways they've never had to before.'

Summer Snake Series: Dusty pygmy rattlesnake is on Florida's venomous list
There are more than 40 species of snakes that are native to Florida, but only six of them are venomous. This week The News-Press and Naples Daily News is taking a closer look at each of these snakes for a special series. Snakes are most active in the spring and early summer months, when the weather warms up and they emerge from brumation, which is similar to hibernation. As it starts to heat up for the summer in Florida, you might see more of your slithery neighbors gliding through your grass or across your driveway. But not every snake is a threat. Here's a closer look at today's featured venomous snake: Dusky pygmy rattlesnakes, also known as pygmy rattlesnakes, have a dark or light gray body, with row of black or charcoal blotches along the length of its body and a reddish-brown stripe running down the middle of the back. Their bites are very painful, but not life-threatening. They can be found throughout the entire state, but aren't known to occur in the Florida Keys, according to the Florida Museum. According to the University of Florida IFAS website, these snakes live in natural wooded areas but can sometimes be found in neightborhoods. To see photos and more in-depth descriptions on these and Florida's native, harmless snakes, visit the Florida Museum's guide for identifying the state's snakes.
