Equine Antebrachial Compartment Syndrome Secondary to Flexor Muscle Myopathy With Subsequent Muscle Atrophy And Tendonitis: A Case Report. J Equine Vet Sci 2021; 101:103462. [PMID: 33993930 DOI: 10.1016/j.jevs.2021.103462] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Revised: 02/25/2021] [Accepted: 03/29/2021] [Indexed: 11/20/2022]
Abstract
This case report describes a 16-year-old jumping stallion that had a marked swelling over the left antebrachial area along with substantial lameness after a fall. The horse was weight bearing but lame (4/5; AAEP scale) at the walk with marked enlargement in the caudal aspect of the antebrachial region. After a static musculoskeletal examination, radiography and ultrasonography the horse was diagnosed with flexor muscle myopathy and presumptive extremity compartment syndrome. Following medical treatment, the horse improved clinically over several days. Six-months post injury the horse showed flexor muscle atrophy but was sound at the walk and trot. The horse was presented again 3 months later with an enlargement of the palmar left metacarpus that was diagnosed as a superficial digital flexor tendonitis. This report describes the episodes from the onset of extremity compartment syndrome until the superficial digital flexor tendonitis, discusses anatomical features of the region, physiopathology of compartment syndrome and the possible biomechanics behind the flexor muscle atrophy and the tendonitis.

Abstract
OBJECTIVE Postoperative compartment syndrome is a reported complication with known patient- and treatment-specific risk factors. Cancer patients carry unique risk factors associated with their underlying disease and long, complex procedures. While elevated serum lactate in traumatic and intensive care settings portends higher risk, no laboratory parameter has demonstrated utility in postoperative risk stratification. Postoperative extremity compartment syndrome in the study institution's cancer population was examined and whether intraoperative serum lactate correlates with postoperative compartment syndrome risk was investigated. METHODS A 1:2 case-control study was performed, which compared cancer patients with postoperative compartment syndrome to those who underwent similar surgical procedures without this complication. Twelve patients were matched to 24 controls by sex, age, surgical procedures, and duration of surgery. Patient and operative variables were analyzed for prognostic significance. RESULTS The compartment syndrome rate was 0.09% of all cases (n = 13,491); 0.12% of cases ≥ 3 h' duration (n = 9,979), and 0.25% of cases ≥ 5 h (n = 4,811). Compared with controls, the case group had higher median BMI (31.7 kg/m2 vs. 25.4 kg/m2, P = 0.001), and median intraoperative lactate level (4.05 mmol/L vs. 1.5 mmol/L, P = 0.047). CONCLUSION Our institutional incidence of postoperative compartment syndrome was similar to that of non-oncologic institutions. While many traditional risk factors did not prove to be influential in our patients, elevated median body mass index and intraoperative serum lactate were identified as risk factors for postoperative compartment syndrome in a cancer population.

Karonen E, Wrede A, Acosta S. Risk Factors for Fasciotomy After Revascularization for Acute Lower Limb Ischaemia. Front Surg 2021; 8:662744. [PMID: 33855045 PMCID: PMC8039517 DOI: 10.3389/fsurg.2021.662744] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Accepted: 03/08/2021] [Indexed: 11/17/2022] Open
Abstract
Background: Acute lower limb ischaemia (ALI) is a life and limb threatening vascular emergency. Acute compartment syndrome (ACS) may develop upon revascularization. The risk of fasciotomy was hypothesized to be decreased in women due to their lower calf muscle mass. The main aim was to evaluate risk factors for fasciotomy after revascularization for ALI. Methods: This is a retrospective observational study of patients undergoing revascularization for ALI between 2001 and 2018. Factors associated with outcome at 1 year in univariable analysis (p < 0.1) were chosen for multi-variable analysis and expressed in Odds Ratios (OR) with 95% confidence intervals (CI). Results: The median age for women (n = 394) was 75 years and men (n = 449) was 70 years (p < 0.001). The frequency of fasciotomy was 10.0% (84/843). The median in-hospital stay was 28 vs. 6 days for patients undergoing fasciotomy and not, respectively (p < 0.001). In adjusted analysis, renal insufficiency (OR 1.77, 95% CI 1.04–3.01), motor deficit (OR 4.40, 95% CI 2.45–7.92), popliteal artery aneurysm thromboembolism (OR 2.26, 95% CI 1.06–4.80), and open vascular surgery (OR 3.43, 95% CI 1.97–5.98) were associated with an increased risk of fasciotomy. Female patients (OR 0.49, 95% CI 0.28–0.84) and anemia (OR 0.52, 95% CI 0.28–0.84) had a lower risk. The major amputation/mortality rate at 1-year was 27.7%; fasciotomy (OR 1.94, 95% CI 1.11–3.40), anemia (OR 1.84, 95% CI 1.24–2.73) and female gender (OR 1.44, 95% CI 1.00–2.08) were independently associated with an increased risk. Conclusions: Female patients had lower rates of fasciotomies, but subsequent higher risk of major amputation/mortality, which may be attributed to inferior results of revascularization. Lower muscle mass and underdiagnosis of ACS could also explain the lower frequency of fasciotomy for female patients. Further studies are needed to better understand gender differences in presentation of ALI, revascularization results and diagnosis of ACS.

BMC Emerg Med 2017; 17:10. [PMID: 28330440 PMCID: PMC5363018 DOI: 10.1186/s12873-017-0120-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2016] [Accepted: 03/04/2017] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Intra-abdominal hypertension (IAH) affects almost every organ sytem.If it is not detected early and corrected, mortality would be high. The prevalence of IAH and abdominal compartment syndrome (ACS) at Kenyatta National Hospital (KNH) critical care units is not known. The aim of this sudy was to determine the prevalence and factors associated with development of IAH/ACS among critically ill surgical patients. METHODS This was a cross sectional descriptive study involving surgical patients in critical care units at KNH, carried out from March 2015 to October 2015. One hundred and thirteen critically ill and ventilated patients 13 years or older were recruited into the study. Krohn's intravesical method was used to measure intra- abdominal pressure (IAP). Measurements were done at first contact, then at 12 and 24 h. Additional parameters recorded included: laboratory tests such as serum bilirubin and total blood count as well as clinical parameters such as urine output, vital signs and peak airway pressure, among others. Frequency, means and standard deviation were used to describe the data. Categorical variables e.g. age, were analysed using Chi square test and continous variables using student 't' test and Mann Whitney test as appropriate RESULT: A total of 113 consecutive surgical patients admitted to the critical care units were recruited. Of our study population, 71.7% (by IAP max) and 67.3% (by IAP mean) had IAH. Abdominal compartment syndrome (ACS) developed in 4.4% of the population. The following factors were significant determinants of risk of IAH : amount of IV fluids over 24 h (3949.6 vs 2931.1, p = 0.003, adjusted OR 1.0 [1.0-1.002]), haemoglobin values at admission (9.9 vs 12.0, p = <0.012, adjusted OR 0.6 [0.4-0.9]), peak airway pressure (28.4 vs 17.3; p = 0.018, adjusted OR 1.6 [1.1-2.4]) and synchronised intermittent mandatory ventilation (SIMV) (60 vs 32; p = 0.041, adjusted OR 1.4 [0.78-2.04]). Of those who had IAH; age, amount of iv fluids over 24 h, fluid balance and ventilator mode were significant determinants of risk of progression to ACS . CONCLUSION The prevalence of intraabdominal hypertension and abdominal compartment syndrome at KNH is high. Clinical parameters pertaining to fluids administration and ventilator mode are siginificant determinants.

Abstract
There is still much debate over the optimal fluid to use for resuscitation. Different studies have indicated either crystalloid or colloid is the ideal intravenous solution to administer, based on mortality or various physiological parameters. Older studies found differences between crystalloids and colloids. However, with the evolving science of fluid administration, more recent studies have shown no differences in patient outcomes. This review article will provide an overview of these substances and discuss the advantages, disadvantages, and implications for giving crystalloids and colloids in clinical practice.

Abstract
Trauma is a leading cause of death worldwide, and almost 30% of trauma deaths are due to blood loss. A number of concerns have been raised regarding the advisability of the classic principles of aggressive crystalloid resuscitation in traumatic hemorrhagic shock. Some recent studies have shown that early volume restoration in certain types of trauma before definite hemostasis may result in accelerated blood loss, hypothermia, and dilutional coagulopathy. This review discusses the advances and changes in protocols in fluid resuscitation and blood transfusion for treatment of traumatic hemorrhage shock. The concept of low volume fluid resuscitation also known as permissive hypotension avoids the adverse effects of early aggressive resuscitation while maintaining a level of tissue perfusion that although lower than normal, is adequate for short periods. Permissive hypotension is part of the damage control resuscitation strategy, which targets the conditions that exacerbate hemorrhage. The elements of this strategy are permissive hypotension, minimization of crystalloid resuscitation, control of hypothermia, prevention of acidosis, and early use of blood products to minimize coagulopathy.

Abstract
BACKGROUND To investigate the effects of fluids resuscitation on pulmonary expression of aquaporin1 and aquaporin5 in a rat model of uncontrolled hemorrhagic shock and infection. METHODS Sixty Sprague-Dawley rats were randomly assigned to five groups, sham operation group (Group C) and four treated groups: no fluid resuscitation group (Group NF), groups resuscitated with Lactated Ringer's (LR),7.5% NaCl (HTS) and Hydroxyl ethyl starch (HES) respectively. Three-phased uncontrolled hemorrhagic shock and infection model was used. Phase I: Massive hemorrhage with a mean arterial pressure of 35-40 mmHg for 60 min, and followed by infection of lipopolysaccharide. Then some animals were resuscitated with solutions mentioned above, until 90 min. Phase II: At hemorrhagic shock 90 minutes, phase II of 60 minutes began with hemostasis and returning of all the initial shed blood. Phase III: Observation phase for 3.5 hours. After phase III, arterial blood gas analysis and the survival rates of the rats were recorded, Wet-to-dry lung weight ratio, BALF protein, pulmonary permeability index, and expressions of aquaporin1 and aquaporin5 were tested. RESULTS The expressions of aquaporin1 and aquaporin5 were decreased in treatment groups comparing with sham operation group. Group HES and Group HTS decreased pulmonary vascular permeability and Wet-to-dry lung weight ratio, improved arterial blood gas analysis and survival rates, and attenuated the decreased pulmonary expression of aquaporin1 and aquaporin5 after the "two-hit", comparing with groups NF and LR,but these beneficial effects were blunted in group HTS. CONCLUSION The expression of aquaporin1 and aquaporin5 may play important roles in formation of pulmonary edema. Resuscitation with HTS and HES, especially HES can reduce lung injury after hemorrhagic shock, partly by up-regulating the expressions of aquaporin1 and aquaporin5.

Abstract
OBJECTIVE To review the human and veterinary literature pertaining to all forms of compartment syndrome (CS). DATA SOURCES Data sources included scientific reviews and original research publications from the human and veterinary literature. HUMAN DATA SYNTHESIS While CS affecting the extremities has been recognized in people for decades, other forms of CS in the abdominal and thoracic cavities are recently gaining more attention. The role of CS in critically ill people is a rapidly growing area of interest. More research on prevention and treatment of CS is being conducted in people because some studies have found mortality rates as high as 80% for those suffering from these conditions. VETERINARY DATA SYNTHESIS While a significant amount of experimental studies of CS have been performed on small animals, there is a marked lack of primary veterinary studies. The majority of the veterinary literature includes case reports and series, and many of these studies were published over a decade ago. However, the increased recognition of CS in people has sparked an interest in veterinary critical care medicine and this has been demonstrated by the recent increased evaluation of compartment pressures in veterinary patients. CONCLUSIONS CS is a complex clinical condition where increased pressure within a compartment can cause significant adverse effects within the compartment as well as throughout the body. Systemic inflammatory responses and local ischemia-reperfusion elements can contribute to the detrimental effects seen in CS. This cascade of events results in increased mortality rates and contributes to the development of CS elsewhere. A better understanding of CS will help veterinarians improve patient care and outcome. Future studies on incidence, prevention, and treatment of CSs in the critical care patient are needed in veterinary medicine.

Abstract
OBJECTIVE To compare fasciotomy rates and Injury Severity Scores (ISSs) before and after tourniquets were fielded for combat casualties in March 2005. METHODS A military trauma registry was used to identify 4332 casualties with limb injury between 2003 and 2006. Descriptive statistics and regression analysis were used to compare changes in ISSs, limb Abbreviated Injury Scale (AIS) scores, and fasciotomy rates. An item of specific interest was whether changes in fasciotomy rates occurred before and after March 2005, when tourniquets were fielded. Therefore, this time point served as a specific comparator in the statistical analyses. RESULTS Among the 4332 limb casualties, 669 (15%) underwent fasciotomy. The ISS doubled (100% increase) during the study. Limb AIS increased 35%. The increase in limb AIS constituted most of the increase in ISS. Monthly fasciotomy rates increased 500% (5% to 30%) during the study. When controlling injury severity (both AIS and ISS), fasciotomy rates tripled (200% increase); but when comparing fasciotomy before and after tourniquet fielding by AIS and ISS, rates only doubled (100% increase). On logistic regression for predicting fasciotomy, the model was unable to determine a good fit for the data because the variables were not significant except weakly for injury severity. CONCLUSIONS During the period of the study, fasciotomy rates increased as a result of a combination of factors: increasing injury severity, increasing use of tourniquets, and increased awareness of the need to perform prophylactic fasciotomy. Further research should be aimed at determining what the optimum rate of fasciotomy is in such an environment.

Abstract
Hemorrhage remains a major cause of preventable death following both civilian and military trauma. The goals of resuscitation in the face of hemorrhagic shock are restoring end-organ perfusion and maintaining tissue oxygenation while attempting definitive control of bleeding. However, if not performed properly, resuscitation can actually exacerbate cellular injury caused by hemorrhagic shock, and the type of fluid used for resuscitation plays an important role in this injury pattern. This article reviews the historical development and scientific underpinnings of modern resuscitation techniques. We summarized data from a number of studies to illustrate the differential effects of commonly used resuscitation fluids, including isotonic crystalloids, natural and artificial colloids, hypertonic and hyperoncotic solutions, and artificial oxygen carriers, on cellular injury and how these relate to clinical practice. The data reveal that a uniformly safe, effective, and practical resuscitation fluid when blood products are unavailable and direct hemorrhage control is delayed has been elusive. Yet, it is logical to prevent this cellular injury through wiser resuscitation strategies than attempting immunomodulation after the damage has already occurred. Thus, we describe how some novel resuscitation strategies aimed at preventing or ameliorating cellular injury may become clinically available in the future.

Abstract
We present a case of emergency tourniquet use of unusually long duration. The patient was wounded during combat operations, and the subsequent battle and evacuation caused a significant delay in surgical treatment of his wounds. Emergency tourniquets can be lifesaving, but are not benign interventions. In general, the extent of tourniquet injury increases with increasing time of application. Despite having a tourniquet in place for 16 hours, the limb was salvaged and significant functional recovery was accomplished. We conducted a search of the published literature including the Medline database, and present a review of the relevant articles concerning emergency tourniquet use, tourniquet injury, and mitigating treatments. Given the widespread use of tourniquets in ongoing military operations, it seems likely that tourniquets will transition to civilian use. Thus it is important for physicians to understand tourniquet injury and appreciate that even extended tourniquet application times does not necessarily doom the affected limb.
