Pain Management intheTrauma Patient

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) denes 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 reected in
the recognized deciency 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
1year 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 thesuccessful 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 signicant 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 modiable risk factors that could impact
the development of chronic pain [9].
Pain Management andClinical 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 andManagement
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 simultaneouslyin major trauma. Moreover,
the identication of symptoms suggestive of neuropathic
pain, such as spontaneous burning pain, paroxysmal pain,
allodynia, paresthesia, painful numbness, or hyperalgesia,
can be useful to guide specic 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 bothside 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. Specically, 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 Table37.2). 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
fortheTrauma 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 signicant 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
benets of performing regional anesthesia, but their widespread use and growing record of safety underlines their
positive risk-to-benet 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 forHip 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 efcacy 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 8–30ml (most commonly 20ml) of longacting local anesthetic (L-bupivicaine, bupivicaine, or
ropivicaine).
Advantages The PENG block is intended to be a motor-
sparing block that produces signicant 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
benecial in rib fracture management and thoracic surgery,
with decreased adverse effects when compared with thoracic
epiduralanalgesia [23]. The goal is to block the ventral and
dorsal rami of the ipsilateral spinal nerves as they exit

thevertebral 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 signicantly 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 etal. 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 benet [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 etal. 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 etal. 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 benet of being able to be performed on a supine
and sedated patient.

Transition toPractice: 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
4hours; 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 inuence. 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 ofHIT inTrauma 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 specic 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 congurability, 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 benets 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 asanEngine forTrauma 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. Dene 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 dened 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 renement 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 benet 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 renement, 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: efcient 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).
