Introduction

In the midst of an unrelenting opioid epidemic in North America, as well as a climbing prevalence of chronic pain in the general population, the topic of pain management has received increasing attention in many different settings, including critical care and trauma medicine. The International Association for the Study of Pain (IASP) denes pain as an “unpleasant sensory and emotional experience associated with actual or potential tissue damage.” Even though pain can be experienced differently by patients with similar con­ditions, inadequately treated pain has several predictable sequelae and potentially deleterious physiologic effects, mediated by neuroendocrine activation as well as activation of the sympathetic nervous system [1].
Acute pain is almost universally present in the trauma patient, being proportional to the severity of tissue damage [2]. The complexity of the trauma patient is often reected in the recognized deciency in pain management including failure to identify, acknowledge, and treat pain both in the prehospital and in-patient setting. This in turn contributes to the high prevalence of chronic pain observed in this popula­tion: more than 60% of patients still report moderate pain 1year after a major trauma [3].
organ systems (Table 37.1). Pain can complicate medical management and has been shown to cause additional mor­bidity in the form of increased length of stay, delayed ambu­lation, and impaired pulmonary mechanics [5, 6].
Long-term sequelae have also been associated with severe and poorly managed pain during trauma hospitalization, including the higher prevalence of chronic pain, as well as major depression and posttraumatic stress disorder [7]. These outcomes may have long-lasting effects on quality of life and ability to return to work, despite thesuccessful treatment of presenting injuries and absence of physical disability. Screening for psychological trauma should be pursued proac­tively and addressed early, reinforcing the value of a multidis­ciplinary acute pain team [8]. Chronic pain in particular acts as both a cause and consequence of psychiatric morbidity in this population. There is signicant overlap in transitioning from acute to chronic pain in the posttraumatic and postsurgi­cal setting, since most pathophysiologic changes stem from tissue injury. Similar risk factors predispose postoperative and trauma patients to chronic pain, such as the presence of thoracic trauma/surgery, major burns, spinal cord injury, pre­existing chronic pain, preexisting anxiety and/or depression, and catastrophizing.Adequate pain control jumps out as one of the few potentially modiable risk factors that could impact the development of chronic pain [9].
Pain Management andClinical Outcomes
Up to 80% of critically ill trauma patients report moderate to severe pain during their hospitalization, and a similar propor­tion of them report their pain being treated inadequately throughout their stay in the intensive care unit [4]. In the acute setting, pain is a potent physiologic stimulus that can trigger a myriad of responses affecting virtually all major

Pain Assessment andManagement
There are a multitude of tools for evaluation of analgesia aimed at sedated and ventilated trauma patients. These include the visual analog scale, behavioral pain scale, and critical pain observation scale. Their implementation, in con­junction with daily interruption of sedation in ventilated patients, have shown to reduce the duration of mechanical ventilation and ICU stay and lead to a decrease in the inci­dence of inadequately treated pain [10, 11]. In heavily sedated patients, sometimes it is necessary to use indirect signs of pain related to heightened sympathetic activity, such as hypertension, tachycardia, agitation, diaphoresis, and lacrimation.
Acknowledging the high prevalence of moderate-to­severe pain in trauma patients, it is preferable to be proactive during the initial phase of management. It can be reasonably assumed that both nociceptive and neuropathic pain compo­nents are present simultaneouslyin major trauma. Moreover, the identication of symptoms suggestive of neuropathic pain, such as spontaneous burning pain, paroxysmal pain, allodynia, paresthesia, painful numbness, or hyperalgesia, can be useful to guide specic therapy in an early and aggressive fashion with the goal of limiting the development of persistent pain syndromes after initial recovery [12].

Pharmacotherapy

Despite the proven effectiveness of multimodal analgesia in pain management, studies have found that many trauma patients receive intravenous opioids as the sole pain modal­ity, which increases the risk of bothside effects and inade­quate pain control [13]. In major trauma, it is not infrequent for patients to display severe pain that cannot be adequately managed on opioids alone, which can be a clue as to the pres­ence of a neuropathic component, frequently seen in com­plex trauma. Adhering to recommendations from the typical “pain ladder” medications, clinicians may be missing a cru­cial therapeutic target for relief. Beard and Wood published their approach to the complex polytrauma patient used to treat soldiers in Afghanistan [14]. In these cases, a neuro­pathic component is assumed a priori, and anti-neuropathic medication is started early. Specically, anticonvulsants such as gabapentin and pregabalin, tricyclic antidepressant medi­cations (TCA) such as amitriptyline or nortriptyline, and other adjuvants such as IV ketamine [15] and IV lidocaine [16] infusions (in a monitored setting such as ICU), and clonidine or dexmedetomidine which are also commonly used to address sedation and delirium. These medications are started in low doses but are accelerated in the young and oth­erwise healthy patients as the initial phase of shock subsides (See Table37.2). As patients progress in the recovery pro-

cess, most can stop antineuropathic medications. Those who have persistent neuropathic pain may require continuing these medications or pursue interventional modalities with a chronic pain specialist.
There are several factors affecting drug’s pharmacokinet­ics in the critically ill trauma patient due to different physi­ologic derangements such as acid-base balance alterations (increased free drug fractions), changes in compartment vol­umes due to shock, edema and/or uid overload and altered splanchnic blood ow (reduction of liver-dependent metabo­lism) due to shock or high dose vasopressor use, as well as the potential for drug interactions in the setting of critical care polypharmacy. These changes in physiology make titra­tion of drugs such as opioids and other sedatives paramount to avoid toxicity, as opposed to dosing regimens based solely on body weight.
Ultrasound-Guided Regional Analgesia fortheTrauma Patient
With the advent of the ultrasound era, interventional pain management and regional anesthesia have been revolution­ized thanks to numerous new procedures described in recent years. Epidural analgesia continues to be the “gold standard” for pain management in several scenarios but comes with disadvantages such as potential for hemodynamic compro­mise, increased risk of hemorrhagic complications in the coagulopathic patient, higher failure rate in the case of tho­racic epidurals, the need for lateral decubitus positioning, as well as a cooperative patient, many of which can be avoided with the use of regional analgesic “nerve blocks” Peripheral nerve catheters can be maintained for longer compared to epidurals without signicant risk of infection, and hemor­rhagic complications are less frequent as well as threatening

[17]. Despite these assurances, practitioners and departments performing regional anesthesia techniques should be trained and equipped to deal with emergencies such as local anes­thetic systemic toxicity (LAST), anaphylaxis, pneumotho­rax, intravascular injections, and brainstem anesthesia. In the trauma patient, preexisting hemodynamic instability, trauma coagulopathy, poor cooperation, and potential for masked compartment syndrome all must be weighed against the benets of performing regional anesthesia, but their wide­spread use and growing record of safety underlines their positive risk-to-benet ratio.
Following is a brief description of regional analgesic tech­niques that have been used effectively in the management of common injuries in the trauma patient. The performance of these techniques requires previous experience with ultra­sound-guided regional analgesia as well as access to resusci­tation equipment as per local or international guidelines [18].
PENG Block forHip Fractures
Hip fractures are a major public health concern as they annually result in hospitalization for over 250,000 adults over the age of 65. Unfortunately, only 60% of patients return to walking post-surgery, and only 50% return to their baseline function. Pain presents a major impediment to recovery, and inadequately treated pain in hospital results in higher levels of delirium, increased length of stay, increased postoperative complications, and reduced func­tion. Opioid analgesia is an effective option; however, it too comes with well-known side effects including nausea, con­stipation, respiratory depression, and delirium. Considering these barriers, the American Academy of Orthopedic Surgeons published practice guidelines with strong levels of evidence to support preoperative regional analgesia and the use of multimodal analgesia in the intra- and postopera­tive period. One such option is the pericapsular nerve group (PENG) block. First described in 2018 by Giron-Arango for use in patients with acute hip fractures, it has gained popularity and expanded use cases into perioperative care due to its efcacy and safety [19, 20].
b
Anatomy The anterior hip capsule is innervated by the femo­ral nerve (FN), obturator nerve (ON), and accessory obturator nerve (AON). Due to the prominence of these three nerves in the capsule, they are the target of the PENG block. Each of these nerves tracks toward the hip joint in the space between the inguinal ligament and the interior surface of the iliac bones. Relevant anatomic landmarks are the iliopsoas muscle and tendon, the femoral artery and femoral vein, the anterior inferior iliac spine (AIIS), and the iliopubic eminence (IPE).
Approach Most authors describe a lateral to medial
approach (see Fig.37.1) although it can be done out-of-plane as well. The goal is to direct the needle deep to the iliopsoas tendon and deposit 8–30ml (most commonly 20ml) of long­acting local anesthetic (L-bupivicaine, bupivicaine, or ropivicaine).
Advantages The PENG block is intended to be a motor-
sparing block that produces signicant reductions in pain scores, time to rst opioid, and total opioid consumption in the hip fracture patient, when compared to other regional techniques such as the fascia iliaca compartment block [21].
While the original article describes preserved motor func­tion in all ve patients, Yu et al. describe two cases with quadricep weakness and inability to perform a straight leg raise [22]. They hypothesized that injection and spread too medially and cephalad resulted in a complete FN and ON block with resultant weakness. Furthermore, a large volume of local anesthetic may result in more cephalad spread and motor block.

Paravertebral Block

The paravertebral block and catheter is a well-established technique to provide prolonged unilateral analgesia and is benecial in rib fracture management and thoracic surgery, with decreased adverse effects when compared with thoracic epiduralanalgesia [23]. The goal is to block the ventral and dorsal rami of the ipsilateral spinal nerves as they exit

thevertebral foramen. The paravertebral space is a potential space bound medially by the vertebral body and interverte­bral disc, anterolaterally by the parietal pleura and intercos­tal space, and posteriorly by the transverse process and superior costotransverse ligament.
This technique is often performed with a transverse probe orientation (see Fig.37.2). The relevant landmarks are the lateral tip of the transverse process, the pleura with its char­acteristic sliding with respiratory motion, and the costotrans­verse ligament. The probe is then minimally slid caudally or cranially to visualize the pleura (Fig.37.2), rather than the rib, creating a path for needle insertion that can be main­tained throughout the block. Successful placement of the needle tip and injection of local anesthetic will result in the parietal pleura being pushed deeper as the pocket of LA expands.
Evidence In 2017, Yeying et al. published a prospective analysis of IV patient-controlled analgesia (PCA) versus paravertebral block and found signicantly lower pain scores in the PVB group. Furthermore, respiratory indices such as PaO2 and FEV1/FVC were improved in the PVB group [24]. Respiratory improvements were also shown in a 2021 retro­spective study of serratus anterior plane blocks, thoracic epi­durals, and paravertebral blocks. They found a reduction in the rapid shallow breathing index (RSBI) for intubated patients immediately after receiving the nerve block [25]. In 2019, Womack etal. published a single-center retrospective analysis of 290 patients over a 4-year period which showed that PVB is a safe and effective analgesic strategy for rib frac­tures; however, it did not demonstrate a mortality benet [26].
One of the pitfalls of paravertebral blocks and catheters is that they are subject to many of the same contraindications as epidurals in regard to catastrophic hemorrhagic complica­tions affecting the spine in patients with bleeding diathesis
[27]. To tackle this issue, several peripheral fascial plane blocks have been described to provide adequate blockade of nociceptive pathways in the trunk and abdomen, such as the serratus plane block, with inherently lower risk of bleeding complications. Despite the existence of multiple types of fas­cial plane blocks for rib fracture analgesia, robust literature is still lacking, and larger prospective studies are needed.

Serratus Plane Block

The SAPB is an ultrasound-guided block targeting the fas­cial plane between the latissimus dorsi muscle and the ser­ratus anterior muscle, usually performed at the level of T5-T6 (see Fig. 37.3), targeting the lateral cutaneous branches of the intercostal nerves T2-T10, making a useful and safe technique for chest wall injuries including rib frac­tures and thoracotomy[25].
Evidence Beard etal. published a comparison of inspira­tory volumes and mean change in pain scores comparing serratus anterior plane block to paravertebral block and thoracic epidurals. Across 354 patients, there was no dif­ference in change of inspiratory volumes or mean change pain scores post block. Notably, 98% of patients reported severe pain prior to the block and only 34% percent post block, and there was no difference between groups [28]. Bhalla etal. demonstrated that SAPB was a viable alter­native to thoracic epidural in the critical care setting for treatment of multiple rib fracture pain. This was demon­strated through measuring post block changes in RSBI and pain scores [25]. Overall, the SAPB provides another option for regional anesthesia in the management of trau­matic rib fracture or other injuries affecting the chest, with the benet of being able to be performed on a supine and sedated patient.

Transition toPractice: Rib Fracture Protocol
Rib fractures are present in 10% of all trauma patients and can lead to altered breathing mechanics, hypoventilation, and impaired gas exchange. Without adequate early man­agement, high-risk patients are at risk of pneumonia and respiratory failure requiring mechanical ventilation. Elderly patients who sustain blunt chest trauma with rib fractures have twice the mortality and thoracic morbidity of younger patients with similar injuries. For each additional rib frac­ture in the elderly, the likelihood of mortality increases by 19% and the likelihood of pneumonia by 16%. High rates of disability and chronic pain are present in those who sur­vive. It has been shown that implementation of a multidis­ciplinary management pathway that includes multimodal pain control and indications for surgical stabilization has been associated with improved outcomes [29].
319
At the author’s institution, a rib fracture management protocol has recently been implemented to improve patient outcomes. The rst step involves calculating a rib fracture score (see Fig. 37.4) to ensure proactive and aggressive analgesic management of patients at risk of severe pain and complications. The treatment algorithm is dynamic and requires pain score reassessment every 4hours; therefore, if a patient continues to have severe pain despite the interventions appropriate to their initial screening, they are advanced to the next level for further analgesic management.
For those patients who begin in, or are advanced to level 3, an Acute Pain Service (APS) consultation is initiated to provide guidance regarding interventions such as a regional anesthesia (epidural for bilateral vs. PVB or SAB catheters for unilateral rib fractures) and ketamine or lidocaine infusions.

Key Points
• Up to 80% of critically ill trauma patients report moderate to severe pain during their hospitaliza­tion. Inadequate pain management in this popula­tion can lead to a myriad of complications both in the short and long term, including physiologic derangements, psychological morbidity, and devel­opment of chronic pain.
• Pain management should always be multimodal in nature, utilizing multiple pain modalities and pharma­cologic agents aimed at targeting different pain recep­tors, as opposed to a high-dose opioid regimen.
• In patients with complex trauma, a neuropathic component of pain should be assumed a priori, and anti-neuropathic medication should be started early and scaled back as patient recovers.
• For injuries affecting the extremities, as well as rib fractures and surgical procedures, ultrasound­guided regional analgesia offers great pain relief with minimal risks. Peripheral nerve blocks, either single shot or continuous, have minimal hemody­namic impact and can be used safely even in coagu­lopathic patients.

Trauma systems have often been at the forefront of innova­tion in healthcare. Advances such as damage control resusci­tation, dedicated trauma units, trauma team dynamics, prehospital transport, regional inclusive trauma systems, and trauma education programs have been nothing short of trans­formational in their impact and inuence. Successful innova­tion in trauma has always engaged deeply with complex

challenges and matched those challenges with fresh perspec­tives from diverse elds.
Now, with the exponential growth in computing power and remarkable advancements in computer user interface design, modern trauma systems are on the brink of new transformational changes. Health information technology (HIT), encompassing the electronic collection, storage, pro­cessing, and exchange of health information [1], presents intriguing opportunities to revolutionize how trauma teams collaborate during resuscitations, approach decision- making, monitor and enhance their performance, and gain valuable insights for injury control and health policy.
This chapter will explore the exciting advances and future opportunities that HIT innovation can offer, from delivery of best practices at the bedside to controlling injury at the popu­lation level.
Current State ofHIT inTrauma Care
Capturing point of care resuscitation data in digital form has the potential to unlock analytic strategies that could trans­form trauma teams’ abilities to predict risk, make decisions under rapidly evolving conditions, and assess and improve performance. Paper records and owsheets, despite their familiarity and their ease of use, especially in acute resusci­tation, are not an effective conduit for the extremely rich data that arise from the point of trauma care. The widespread transition to electronic health records (EHRs) seen around the world offers the promise of digital data capture and data analysis.
Efforts to harness EHR data to support continuous quality improvement have shown some early successes. For exam­ple, Kannan and colleagues [2] generated specic clinical registries from a legacy EHR by implementing data collection

principles, developing data warehousing solutions, and employing agile development strategies. Within a year, they created 43 specialty chronic disease registries with hundreds of decision support tools, quality metrics, and dashboards to support process-mapping of care and continuous quality improvement [2]. However, to date, EHRs have not been widely adapted to support trauma systems optimization.
For this purpose, trauma systems continue to rely on trauma registries to inform performance improvement and to support clinical research. While these registries have been instrumental in trauma systems development for generations, their use in modern big data environments is limited by chal­lenges such as data entry delays, limited congurability, and the absence of high-resolution data with precise time­stamping. Additionally, manual abstraction of health record data to populate trauma registries is costly and excludes resource-constrained centers from the benets of conven­tional trauma systems quality improvement. Ideally, the next generation of HIT would combine the agility of paper docu­mentation with the promise of digital data collection and rapid analysis while serving as an interoperable front end for conventional legacy EHRs.
HIT asanEngine forTrauma System Design Thinking
By employing design thinking, we can shift our focus from a technology-driven perspective to a user-centric mindset, ensuring that the solutions we develop truly address the needs and challenges of the people involved.
There are ve key steps to the design thinking approach:
1. Empathize: Gain insight from individuals and systems affected by trauma care, such as patients, healthcare pro­viders, and administrators. This involves actively listen­ing, conducting observations, and engaging in meaningful conversations to gain insights into their experiences, pain points, and aspirations.
2. Dene the problem: Reframe the problem by narrowing down the focus and identifying the core needs and oppor­tunities for improvement based on insights gained from empathy.
3. Ideate: Generate a wide range of ideas and potential solu­tions to address the dened problem.
4. Prototype: Create low-delity prototypes of potential solutions and gather feedback from end-users and stakeholders.
5. Test and iterate: Foster a culture of continuous learning and improvement through iterative renement of solu­tions, incorporating feedback and data analysis and adapting to evolving needs. This ensures that innovations remain effective and relevant over time.
The utilization of modern health information technology tools could empower trauma systems to tap into vast amounts of multi-dimensional, high-resolution, time-stamped data generated throughout the patient care process. This wealth of information, made accessible through seamless ow through the digital ecosystem to intuitive user interfaces, serves as an engine for driving solutions across the entire spectrum of trauma care. From trauma resuscitations in the trauma bay to system-level injury prevention strategies, data can be har­nessed to enhance patient outcomes and promote equity in healthcare.
Transforming insights from raw data (or even from sophisticated data analysis) to effective action that improves trauma system performance may require a critical intermedi­ate step. Design thinking is an iterative and human-centered approach to problem-solving and innovation [3]. It empha­sizes empathy, collaboration, and a deep understanding of user needs to generate creative and effective solutions [4, 5].
Almost all of these steps would benet from the collec­tion of multidimensional, high-resolution data. By integrat­ing high-resolution data into the design thinking process, trauma teams can measure the impact of their solutions and implement iterative improvements based on evidence. This iterative cycle of data analysis, solution renement, and con­tinuous learning ensures that solutions are responsive to the evolving needs of trauma care and can drive meaningful and sustained improvements in the trauma ecosystem.
The design thinking framework, powered by point of care data, can be applied to data ow and analyses at sev­eral scales: efcient and complete documentation and pop­ulation of conventional EHRs, trauma team situation awareness, decision support in trauma resuscitation, trauma care quality improvement, trauma research, and trauma systems design, including injury prevention and access to high quality trauma care in highly integrated trauma net­works (Fig.38.1).
