Inflammation-related proteomics demonstrate landscape of fracture blister fluid in patients with acute compartment syndrome.

Background: Blisters are tense vesicles or bullae that arise on swollen skin and are found in a wide range of injuries. As a complication of fracture, fracture blisters are considered soft tissue injuries, which often lead to adverse effects such as prolonged preoperative waiting time and increased risk of surgical site infection. However, our previous study found that in patients with acute compartment syndrome, fracture blisters may be a form of compartment pressure release, but the specific mechanism has not been revealed. Here, we mapped out the proteomic landscape of fracture blister fluid for the first time and compared its expression profile to cupping and burn blisters. Methods: First, fluid samples were collected from 15 patients with fracture blisters, 7 patients with cupping blisters, and 9 patients with burn blisters. Then, the expression levels of 92 inflammatory proteins were measured using the Olink Target 96 Inflammation panel. Protein profiles were compared across the three groups using Differential Protein Expression Analysis and Principal Component Analysis (PCA). Results: Fracture blisters had significantly higher levels of 50 proteins in comparison to cupping and 26 proteins in comparison to burn blisters. Notably, PCA showed fracture blisters closely resembled the protein expression profile of burn blisters but were distinct from the protein expression profile of cupping blisters. Conclusion: Our study provides the first characterization of fracture blister fluid using proteomics, which provides a valuable reference for further analysis of the difference between blisters caused by fractures and those caused by other pathogenic factors. This compendium of proteomic data provides valuable insights and a rich resource to better understand fracture blisters.

Enzymatic debridement for circumferential deep burns: the role of surgical escharotomy.

INTRODUCTION: Circumferential deep burns carry a high risk for a burn induced compartment syndrome. It was recently shown that an enzymatic bromelain-based debridement with Nexobrid® is a safe and efficient procedure to release pressure in deep circumferential extremity burns reducing the need for surgical escharotomy. We therefore herein aimed to analyze the conceptual relation between Nexobrid® and surgical escharotomy. PATIENTS AND METHODS: We conducted a retrospective study on all patients with circumferential deep partial-thickness or full-thickness burns requiring immediate escharotomy that was either performed by surgical incision or Nexobrid®. Medical records of 792 patients that were treated at the burn center of the University Hospital Zurich between 2016 and 2021 were analyzed. RESULTS: Overall, 62 patients with circumferential deep partial-thickness or full-thickness burns who received preventive decompression either by Nexobrid® (N = 29) or surgical escharotomy (N = 33), were included. Whilst distribution of age, sex, BMI and type of injury showed no difference between the groups, the ABSI score, TBSA, percentage of third degree burns and mortality were significantly higher in patients who received a surgical escharotomy. CONCLUSION: While the use of Nexobrid® to prevent burn induced compartment syndrome has steadily increased, surgical escharotomies were predominantly performed in severely burned patients with a high degree of full-thickness burns. Thus, higher mortality in this patient group needs to be considered with caution and is mainly attributed to the higher TBSA. Although evidence is lacking for the use of Nexobrid® for larger body areas exceeding 15%, escharotomy is also the more reliable and faster approach in such critically burned patients.

Compartment syndrome following a jellyfish sting: a case report.

BACKGROUND: While the majority of reported cases of jellyfish envenomation are self-limited with few lasting complications, a few can cause life-threatening and debilitating illnesses. We present the case of a 15-year-old male who had an unusual presentation of a jellyfish sting that led to acute compartment syndrome. CASE PRESENTATION: A 15-year-old Lebanese (Arab) boy was stung by a jellyfish, which led to acute compartment syndrome in the left arm. Decompression fasciotomy and local application of diluted nitroglycerin helped to relieve the ulnar and radial artery spasms. The patient was left with shoulder and elbow pain and elbow flexion weakness, which improved after physiotherapy over a period of 6 weeks. CONCLUSIONS: Current therapy recommendations for acute compartment syndrome following jellyfish stings are mainly based on case reports. Urgent fasciotomy and local application of nitroglycerin have been demonstrated to be helpful in severe jellyfish stings associated with acute compartment syndrome.

Acute Extremity Compartment Syndrome and (Regional): Anesthesia: The Monster Under the Bed.

Acute compartment syndrome (ACS) is a potential orthopedic emergency that leads, without prompt diagnosis and immediate treatment with surgical fasciotomy, to permanent disability. The role of regional anesthesia (RA) for analgesia in patients at risk for ACS remains unjustifiably controversial. This critical review aims to improve the perception of the published literature to answer the question, whether RA techniques actually delay or may even help to hasten the diagnosis of ACS. According to literature, peripheral RA alone does not delay ACS diagnosis and surgical treatment. Only in 4 clinical cases, epidural analgesia was associated with delayed ACS diagnosis.

The role of hyperbaric oxygen for acute traumatic ischemias.

Acute traumatic ischemias are an array of disorders that range from crush injuries to compartment syndromes, from burns to frostbite and from threatened flaps to compromised reimplantations. Two unifying components common to these conditions are a history of trauma be it physical, thermal, or surgical coupled with ischemia to the traumatized tissues. Their pathophysiology resolves around the self-perpetuating cycle of edema and ischemia, and their severity represents a spectrum from mild, almost non-existent, to tissue death. Since ischemia is a fundamental component of the traumatic ischemias and hypoxia is a consequence of ischemia, hyperbaric oxygen is a logical intervention for those conditions where tissue survival, infection control and healing is at risk. Unfortunately, even with mechanisms of hyperbaric oxygen that strongly support its usefulness in traumatic ischemias coupled with supportive clinical data, clinicians are disinclined to utilize it for these conditions. This focuses on the orthopedic aspects of the traumatic ischemias, namely crush injury and compartment syndrome, and show how hyperbaric oxygen treatments can mitigate their severity.

Stimulated biofeedback training for a child with Becker muscular dystrophy and compartment syndrome in the left forearm.

BACKGROUND: Muscular dystrophy negatively affects ambulation, mobility, self-care, and community involvement. Neonatal compartment syndrome (NCS) causes loss of muscle strength, sensory problems, and limb dysfunction. Patients with Becker Muscular Dystrophy (BMD) and/or NCS may benefit from individualized rehabilitation to improve function. PURPOSE: This case report describes stimulated biofeedback training (SBT) to improve the functional level, muscle strength, balance, and hand function in a child with BMD and NCS. CASE DESCRIPTION: An 8-year-old male patient with BMD and NCS in the left forearm received 12-weeks of SBT. The functional level was assessed by the Motor Function Measurement-32 (MFM-32), muscle strength by a hand-held dynamometer, balance by the Neurocom Balance Master, and upper limb function by the Quality of Upper Extremity Skills Test (QUEST) at the initial examination, after 6 weeks and after 12 weeks of treatment. Laboratory tests to monitor changes in serum creatine kinase were performed throughout the episode of care. OUTCOMES: The laboratory values remained within the appropriate range to continue SBT. Functional level, hand function, hip, and knee flexion/extension strength, and dorsiflexion strength improved. CONCLUSIONS: This case report suggests that SBT safely and effectively improved functional level, muscle strength, and hand function in this child with BMD and NCS.

Insidious Onset Compartment Syndrome of the Forearm in a Teenager: A Case Report and Review of the Literature.

Compartment syndrome affecting the upper extremities is a relatively underreported event compared with compartment syndrome affecting the lower extremities. Moreover, insidious onset forearm compartment syndrome has been rarely reported and is usually limited to single case reports. We report a compartment syndrome of the forearm in a teenager. She hit her right proximal forearm lightly on the cash register, but there was no pain. However, the next day, she had difficulty in moving her right hand. Although she underwent electrotherapy, her right forearm gradually became swollen, and she felt numbness in the ring and little fingers of her right hand. Six day after the onset, she came to our hospital and underwent fasciotomy. There was no aftereffect, and very good functional recovery was obtained. All clinicians need to keep the case of forearm compartment syndrome in a young individual with a diffuse course, such as in this case in mind.

Successful adjunctive treatment of compartment syndrome due to acute isocyanate inhalation using hyperbaric oxygen therapy: case report.

Introduction: Isocyanates are the raw materials that make up all polyurethane products. Isocyanate is a powerful irritant to the mucosal membrane of the respiratory tract, eyes and skin. Pulmonary symptoms, especially occupational asthma, are predominant manifestations of isocyanate toxicity. Case report: We report mental changes and compartment syndrome complicated with rhabdomyolysis as an extraordinary manifestation of acute isocyanate toxicity observed in a patient during the waterproofing of a water tank. A 58-year-old man recovered consciousness after six hours in the emergency department and complained of severe pain in the lower leg. The results of his laboratory test showed that his serum creatine kinase (15,250 IU/L) level had increased. The tissue pressure in both the lower legs had increased to 180 mmHg/170 mmHg (right/left). We performed fasciotomy on the second day of hospitalization. The patient was provided hyperbaric oxygen (HBO2) therapy of 2.0 ATA for 90 minutes twice a day for seven days. His condition gradually improved over five months, and he did not require amputation. He had a mild neurological disorder in his foot and was transferred to a rehabilitation center five months after hospitalization. Conclusion: It is important to note that when working with isocyanate, non-specific complications such as a change in consciousness as well as compartment syndrome with rhabdomyolysis can occur in a confined space or high-temperature environment. In addition, we found that compartment syndrome caused by isocyanate toxicity can be effectively treated with fasciotomy and HBO2 therapy.

Defining the Role of Hyperbaric Oxygen Therapy as an Adjunct to Reconstructive Surgery.

The discipline of reconstructive surgery has been slow to accept the role of hyperbaric oxygen therapy (HBOT) as an adjunct to surgery, despite clinical and experimental data showing potential benefits. Obstacles prevent this acceptance; one of the most potent is surgeon bias. This article attempts to lessen this bias by reviewing the benefits of HBOT in conditions where there is uniform acceptance of its role, such as carbon monoxide poisoning and decompression illness. It demonstrates that these conditions have similar pathophysiologic derangements to conditions commonly encountered by the reconstructive/wound care surgeon, including crush injuries, compartment syndrome, compromised flaps, and thermal burns.

Releasing Burn-Induced Compartment Syndrome by Enzymatic Escharotomy-Debridement: A Case Study.

Burn-induced compartment syndrome represents a serious and acute condition in deep circumferential burns of the extremities which, if left untreated, can cause severe complications. The surgical escharotomy that releases the high subdermal pressure is the therapeutic treatment of choice for burn-induced compartment syndrome. Guidelines for escharotomy indications and timing include pressure greater than 30 mm Hg and 6 Ps (Pain, Pallor, Paresthesia, Paralysis, Pulseless, and Poikilothermia). Nevertheless, despite the need for an early as possible pressure release, escharotomy is often delayed when a capable surgeon is not available, or if the indication is not completely clear to justify potential risks associated with surgical escharotomy. Early treatment of circumferential burns of the extremities with a Bromelain-based enzymatic agent NexoBrid® may represent a less traumatic and invasive procedure to reduce intra-compartmental pressure, replacing surgical escharotomy. This case study of 23 patients describes the variation of compartmental pressure in patients with circumferential burns of the extremities treated with NexoBrid® enzymatic escharotomy-debridement. All the patients were treated with NexoBrid® within 2 to 22 hours post-injury in our Burn Intensive Care Center. The excessive pressure recorded before treatment returned to normal below 30 mm Hg and an approximately 60% reduction of the compartmental pressure was observed in most cases within 1 hour from NXB application. On NexoBrid® removal after 4 hours complete debridement-escharotomy of the burns was achieved. Enzymatic escharotomy-debridement appears to be a useful and safe method to reduce postburn compartmental pressure. Additional randomized, well-controlled powered studies are needed to further support these results.

Utilization of Fluorescence Microangiography in Pediatric Acute Compartment Syndrome: A Case Report.

Acute compartment syndrome is a critical condition, most commonly arising as the result of high-energy trauma, fracture, and crush injury. Early diagnosis and treatment are imperative to avoid permanent functional damage to the affected extremity. Although isolated pedal compartment syndrome is well studied in adults, in the pediatric population, it has been seldom reported. Pediatric patients pose a unique challenge when diagnosing compartment syndrome. Their inability to appropriately verbalize symptoms and participate in physical examinations often causes a delay in diagnosis. We present the case of a 5-year-old female who developed compartment syndrome of her left foot 26 hours after sustaining an isolated crush injury to the distal forefoot. Her treatment included emergent fasciotomy in combination with 20 hyperbaric oxygen therapy treatments. The progression of her acute digital ischemia was monitored by using serial fluorescence microangiography studies performed at 17 hours, 7 days, and 3 weeks postinjury. Throughout these serial studies, improvement in hypofluorescence was noted involving the dorsolateral midfoot, as well as digits 3, 4, and 5, which correlated with physical examination. The patient went on to uneventfully autoamputate the distal aspects of digits 4 and 5 within 4 months of injury. At the 12-month follow-up visit, she denied any pain, sensory deficits, or functional disability and had returned to all preinjury activities. Our case study demonstrates the use of serial microangiography to monitor progression of acute ischemia associated with acute pediatric compartment syndrome and discusses prognostic capabilities.

Feasibility and safety of enzymatic debridement for the prevention of operative escharotomy in circumferential deep burns of the distal upper extremity.

BACKGROUND: Burn-induced compartment syndrome is a severe sequela after circumferential burns of the extremities and is avoidable by immediate release of the underlying pressure under the eschar. Although the current gold standard is operative escharotomy, this procedure carries considerable morbidity. Our study evaluates the safety and effectiveness of immediate enzymatic debridement to prevent the need for operative escharotomy because of burn-induced compartment syndrome in selected patients. PATIENTS AND METHODS: From 2015 to 2017, all patients suffering from deep circumferential burns of the upper extremities requiring operative escharotomy were potential candidates for the treatment algorithm evaluated by this study. Exclusion criteria involved burn trauma > 12 hours, clinically established burn-induced compartment syndrome, intolerance to the enzymatic debriding agent, dry burns requiring presoaking, as well as blast and electrical injuries requiring fasciotomy or carpal tunnel release. All patients with the inclusion criteria received enzymatic debridement with Nexobrid immediately after admission to our burn center. Enzymatic debridement was applied according to the manufacturer's recommendations. After enzymatic debridement, extremities were revisited every 2 hours for 24 hours to determine the need for conversion to conventional operative escharotomy. The indication for and time to skin grafting was reviewed, and functional outcomes assessed during follow-up examination. RESULTS: Included in this sturdy were 13 patients with 20 burned upper extremities. Enzymatic debridement provided a sufficient eschar removal in all patients. Conversion to conventional operative escharotomy was thus not necessary in any patient. Secondary skin grafting was required in 9 patients. Functional outcomes were favorable 11.9 months after burn trauma. CONCLUSION: If the specific contraindications are respected, enzymatic debridement is safe and effective for the prevention of burn-induced compartment syndrome after deep circumferential burns at the upper extremity, and thus making operative escharotomy unnecessary.

Medical Management of Acute Pancreatitis: Intravenous Fluid, Nutrition and Antimicrobial Therapy / 대한췌담도학회지

Acute pancreatitis is one of the most common diseases of the pancreas. Although the incidence of acute pancreatitis is increasing, the mortality is decreasing. In general, most of fatal cases occur within 2 weeks after admission due to multi-organ failure. Initial medical treatment of acute pancreatitis is important in order to improve the prognosis of the patients with acute pancreatitis. Essential treatment in this early period includes intravenous hydration, paint control, enteral nutrition, and antimicrobial therapy. Although aggressive intravenous hydration with lactated Ringer's solution can improve mortality rates and decrease the development of systemic inflammatory response syndrome in the patients with acute pancreatitis, fluid overload can induce pulmonary edema, increase of the extra-pancreatic fluid collection, intra-abdominal compartment syndrome, sepsis, and increase of the mortality. Therefore, goal-directed therapy, utilizing various parameters to guide fluid administration, reduces the risk of persistent single or multiple organ system failure, infected pancreatic necrosis or mortality from acute pancreatitis. Initiation of early oral feeding is recommended, beginning within 24 hours for mild acute pancreatitis. Enteral nutritional support is favored over parental nutrition in severe acute pancreatitis. Recent guidelines do not support the use of prophylactic antibiotics to prevent infection in necrotizing acute pancreatitis and severe acute pancreatitis.

Acute Compartment Syndrome after Anticoagulant Therapy to Misdiagnosed Deep Vein Thrombosis / 대한정형외과학회잡지

Acute compartment syndrome, which is an orthopedic emergency, induces irreversible tissue necrosis by increasing the compartment pressure. In serious cases, this event may result in functional impairment, loss of the lower limb, and death by renal failure. When the patient initially presents with pain and swelling that are similar to deep vein thrombosis, a differential diagnosis between the two diseases is very critical. The authors encountered a case of acute compartment syndrome after anticoagulant therapy in a patient presenting with painful swelling of the left leg following a massage that was initially misdiagnosed as deep vein thrombosis. A fasciotomy was performed on this case with satisfactory results. This paper reports this case with a review of the relevant literature.

Compartment syndrome secondary to an atraumatic gastrocnemius tear in a patient on NOACs: presentation and complications of treatment.

Acute compartment syndrome is a limb-threatening condition often associated with high-energy injury. We present the case of a man who sustained compartment syndrome secondary to an atraumatic tear in the gastrocnemius muscle and the complications which arose in his treatment due to his being on rivaroxaban.

Hyperbaric oxygen therapy as treatment for bilateral arm compartment syndrome after CrossFit: case report and literature review.

INTRODUCTION: CrossFit is a physical fitness program characterized by high-intensity workouts that can be associated with serious injury. Acute compartment syndrome in the upper limbs is a rare occurrence. It may occur after intense physical exercise, and its usual treatment is surgical. Hyperbaric oxygen therapy is a treatment described as adjunctive in cases of compartmental syndrome. PRESENTATION: We describe the case of a CrossFit practitioner who, after intense training, developed progressive symptoms of rhabdomyolysis and acute bilateral arm compartment syndrome, who was successfully treated with hyperbaric oxygen therapy and required no fasciotomy as surgical treatment. CONCLUSIONS: Acute compartment syndrome in the arms after intense physical exercise is a rare occurrence that should be suspected by practitioners of physical activity experiencing intense, disproportionate and progressive pain. In the case presented, hyperbaric oxygen therapy was successfully used in the treatment of the disorder, with satisfactory progress, and without the need for a surgical fasciotomy as therapy.

Perception of Community and Hospital Personnel on Burn Treatment and Outcome in Nepal.

INTRODUCTION: Globally, eleven million people sustain burn injuries every year enough to require medical attention. WHO has estimated Disability associated limited years of 84,000 per year just due to deformities and 2100 people die every year due to burn injuries in Nepal. The overall objective of the study is to explore the effectiveness of burn injuries treatment and management approach of hospitals. METHODS: This qualitative study approached to 40 Health Personnel for Key Informants Interviews and 18 Focus Group Discussions with community people at the ten referral hospitals of eight district from May-June 2016. Qualitative data were analyzed using AtLas.ti software. RESULTS: Female burn victims are brought late to the hospital compared to male patients and false reporting about incident is usually done by her attendants. More than three-fourth (80%) of the hospitals and about one-third male and female from FGD reported that the community people seek home remedy first rather than medical treatment. Majority of the medical doctors and nursing chiefs reported that first degree cases accounts for 50% of the total burn cases with a success rate of 80%. Medical and Nursing staff reported that deformities like hypertrophic scar, keloids, joint stiffness and compartment syndrome are mostly observed during the treatment. Hypothermia and sepsis were the major causes of death in most of the burn patients. CONCLUSIONS: Usually, people who engaged in house and agriculture works, have visited public health posts/hospitals more frequently due to financial constraints and transportation issues where quality of burn care services are unavailable.

Dietary Supplement-Drug Interaction-Induced Serotonin Syndrome Progressing to Acute Compartment Syndrome.

BACKGROUND Dietary supplements have been associated with an increase in emergency intervention as a result of unexpected adverse events. Limited resources and information on significant drug-drug interactions with dietary supplements and prescription medications have contributed to associated complications and unexpected events. We present the case of a patient who consumed multiple prescription medications and dietary supplements which resulted in significant complications. CASE REPORT A 28-year-old man presented to the Emergency Department complaining of severe calf pain after exercising. In addition to his prescription medications, which included sertraline, he also consumed dietary supplements prior to his workout. He developed serotonin syndrome with rhabdomyolysis, which rapidly progressed to acute compartment syndrome. An emergency bilateral four-compartment double-incision lower extremity and forearm fasciotomy was performed, with complete recovery. CONCLUSIONS Drug-drug interactions involving dietary supplements are frequently overlooked in most healthcare settings, especially in the Emergency Department. Health care providers should be cognizant of the potential drug- drug interactions resulting in serotonin syndrome to prevent the progression to acute compartment syndrome and associated complications. Pharmacists play a key role in recognizing drug-dietary supplement interactions and adverse effects.

Nonoperative Management of Chronic Exertional Compartment Syndrome: A Systematic Review.

Although nonoperative treatment options for chronic exertional compartment syndrome (CECS) are often used in clinical practice, supporting evidence is limited. The objective of this study was to systematically review the literature for nonsurgical treatment options for CECS of the lower leg. The literature search identified seven articles describing in total four different treatment options: massage, gait changes, chemodenervation, and ultrasound-guided (USG) fascial fenestration. Pertinent studies were in the form of case series and one case report, which limited the robustness of the data. Nevertheless, all four treatment options have little to no reported adverse effect profiles and can be considered in clinical practice. In addition, gait changes and USG fascial fenestration were found to have continued effect at 1 and 1.5 years, respectively.
