Toxic Megacolon – A Three Case Presentation
Introduction: Toxic megacolon is a life-threatening disease and is one of the most serious complications of Clostridium difficile infection (CDI), usually needing prompt surgical intervention. Early diagnosis and adequate medical treatment are mandatory.
Cases presentation: In the last two years, three Caucasian female patients have been diagnosed with toxic megacolon and treated in the Clinical Infectious Diseases Hospital, Constanta. All patients had been hospitalized for non-related conditions. The first patient was in chemotherapy for non-Hodgkin’s lymphoma, the second patient had undergone surgery for colon cancer, and the third patient had surgery for disc herniation. In all cases the toxin test (A+B) was positive and ribotype 027 was present. Abdominal CT examination, both native and after intravenous contrast, showed significant colon dilation, with marked thickening of the wall. Resolution of the condition did not occur using the standard treatment of metronidazole and oral vancomycin, therefore the therapy was altered in two cases using intracolonic administration of vancomycin and intravenous tigecycline.
Conclusions: In these three cases of CDI, the risk factors for severe evolution were: concurrent malignancy, renal failure, obesity, and immune deficiencies. Ribotype 027, a marker for a virulent strain of CD, was found in all three cases complicated by toxic megacolon. The intracolonic administration of vancomycin, and intravenous tigecycline was successful when prior standard therapy had failed, and surgery was avoided.
Simulation-based Training as Perceived by Young Anesthesiology and Intensive Care Residents
Medical simulation-based teaching includes a variety of educational techniques used to complement actual patient experiences with true-to-life yet artificial tasks.
This field is rapidly growing and is widely used in critical care graduate medical education programs, having teaching, learning and assessment roles.
Its use is on the increase due to many factors including patient discontent with being “practiced on”, current considerations regarding patient safety, and the significance of early attainment of complex medical proficiencies. Simulation-based assessment (SBA) is advancing to the point where it can revolutionize the way clinical competence is assessed in residency training programs. [More]
Anaesthesia and Intensive Care Residents’ Perception of Simulation Training in Four Romanian Centres
Introduction: Simulation training offers an opportunity to educate anaesthesia and intensive care (AIC) residents safely. At present, it is not yet a mandatory part of residency curriculum.
The aim of the study was to evaluate the residents’ perception of the inclusion of simulation-based training in the Romanian AIC residency program.
Material and methods: Romanian AICs in anaesthesia and intensive care from four training centres completed a twenty-question survey regarding their views on simulation during their residency training. Residents were divided into junior, in the first three years, or senior groups, in the last two years of residency training. The questionnaire included Likert-scale multiple-choice, open-ended, and “yes” or “no” questions regarding simulator learning, the frequency of simulation sessions, and the value of the simulation sessions in improving practice, skills or teamwork. The open-ended questions, asked which were the respondents’ preferred topics to be included in simulation sessions.
Results: Fifty-six percent of residents completed and returned the questionnaire. Ninety-eight percent of them considered simulation-learning useful once a month or every three months especially in the first two years of training. All residents thought simulation sessions would improve their skills, communication abilities, and teamwork. Senior residents paid more attention to clinical scenarios (p=0.007), haemodynamic monitoring (p=0.017) and mechanical ventilation (p=0.004) as compared to juniors. All residents considered difficult airway management, and cardiac life support to be very important issues to be included in simulation sessions.
Conclusion: The survey demonstrated that simulation-based training should play a greater role and eventually became compulsory in training program in AIC academic centres.
The Relevance of Coding Gene Polymorphysms of Cytokines and Cellular Receptors in Sepsis
Sepsis is an injurious systemic host response to infection, which can often lead to septic shock and death. Recently, the immune-pathogenesis and genomics of sepsis have become a research topic focusing on the establishment of diagnostic and prognostic biomarkers. As yet, none have been identified as having the necessary specificity to be used independently of other factors in this respect. However the accumulation of current evidence regarding genetic variations, especially the single nucleotide polymorphisms (SNPs) of cytokines and other innate immunity determinants, partially explains the susceptibility and individual differences of patients with regard to the evolution of sepsis. This article outlines the role of genetic variation of some serum proteins which have the potential to be used as biomarker values in evaluating sepsis susceptibility and the progression of the condition.
Neutrophil Gelatinase-Associated Lipocalin as a Marker for Renal Dysfunction Detection in Critically Ill Patients with Increased Intraabdominal Pressure
Introduction: Elevated intraabdominal pressure (IAP) it is known to have an impact on renal function trough the pressure transmitted from the abdominal cavity to the vasculature responsible for the renal blood flow. Intraabdominal pressure is found to be frequent in intensive care patients and also to be a predictor of mortality. Intra- abdominal high pressure is an entity that can have serious impact on intensive care admitted patients, studies concluding that if this condition progresses to abdominal compartment syndrome mortality is as high as 80%.
Aim: The aim of this study was to observe if a link between increased intraabdominal pressure and modification in renal function exists (NGAL, creatinine clearance).
Material and Method: The study enrolled 30 critically ill patients admitted in the Intensive Care Unit of SCJU Tîrgu Mures between November 2015 and August 2016. The study enrolled adult, hemodynamically stable patients admitted in intensive critical care – defined by a normal blood pressure maintained without any vasopressor or inotropic support, invasive monitoring using PICCO device and abdominal pressure monitoring.
Results: The patients were divided into two groups based on the intraabdominal pressure values: normal intraabdominal pressure group= 52 values and increased intraabdominal group= 35 values. We compared the groups in the light of NGAL values, 24 hours diuresis, GFR and creatinine clearance. The groups are significantly different when compared in the light of NGAL values and GFR values. We obtained a statistically significant correlation between NGAL value and 24 hour diuresis. No other significant correlations were encountered between the studied items.
Conclusions: NGAL values are increased in patients with high intraabdominal pressure which may suggest its utility as a cut off marker for patients with increased intraabdominal pressure. There is a significant decreased GFR in patient with elevated intraabdominal pressure, observation which can help in early detection of renal injury in patients due to high intraabdominal pressure. No correlation was found between creatinine clearance and increased intraabdominal pressure.
Emergency Surgery in a Critically Ill Patient with Major Drug-Induced Bleeding and Severe Ischaemic Heart Failure
Introduction: Anticoagulant overdose frequently occurs in elderly populations especially in remote areas where medical services are scarce. When emergency surgery is required, such patients offer major anaesthetic challenges.
Case presentation: We describe the case of an elderly patient admitted to a surgical ward with acute abdominal pain, on dual anti-platelet therapy and acenocoumarol for a recent acute myocardial infarction treated percutaneously with two drug-eluting stents. Laboratory tests showed severe anticoagulant overdose with uncoagulable INR. The decision was made to use of both light transmission aggregometry [LTA] for platelet function testing and thromboelastography to aid in the management of perioperative haemostasis in order to prevent both severe bleeding and stent thrombosis. Surgery revealed haemoperitoneum, volvulus of the ileum and a venous mesenteric infarction. Intraoperative blood loss was minimal and no blood products were administered. Postoperative course was uneventful without either thrombotic or haemorrhagic complications and the patient was discharged from the Postanaesthesia Care Unit on postoperative day two.
Conclusion: The use of aggregometry and thrombography helped in both evaluation and management of haemostasis of a high-risk patient by goal-directed administration of pro-and anti- coagulants.
Pulse Oximetry During the First 24 Hours as a Screening Tool For Congenital Heart Defects
Introduction: Although screening for congenital heart defects (CHD) relies mainly on antenatal ultrasonography and clinical examination after birth, life-threatening cardiac malformations are often not diagnosed before the patient is discharged.
Aim: To assess the use of routine pulse oximetry in the delivery room and at 24 hours postpartum, and to study its feasibility as a screening test for CHD.
Material and Methods: In this prospective study, all infants born in “Cuza Voda” Maternity Hospital, Iasi, Romania, were enrolled over a thirteen-month period. Preductal oximetry was assessed during the first hour, and postductal oximetry was evaluated at twenty-four hours postpartum. Data were then analyzed to establish the sensitivity and specificity of pulse oximetry, as a screening test for CHD.
Results: 5406 infants were included in the study, with a mean gestational age of 38.2 weeks and a mean birth weight of 3175 grams. During the first minute, blood oxygen saturation varied between 40% and 90% and at 24 hours of life, it ranged between 90% and 100%. Following oximetry assessment, 14 infants with critical CHD were identified. Blood oxygen saturation values in infants with CHD were lower throughout the entire period of evaluation. Pulse oximetry had good sensitivity and specificity at 1 hour (Se=87.5%, Sp=95.5%) and 24 hours (Se=92.5%, Sp=97.4%) for the diagnosis of CHD. Blood oxygen saturation values at one minute, 1 hour and 24 hours are strong discriminative parameters for the early diagnosis of CHD.
Conclusion: Routine pulse oximetry during the first 24 hours postpartum represents an early indicator of CHD to facilitate timely intervention. Pulse oximetry provides excellent sensitivity and specificity and has tremendous potential as a standard screening test for CHD during the first 24 hours of life.
Toxic Epidermal Necrolysis – A Case Report
Toxic epidermal necrolysis (TEN) is an acute, life-threatening muco-cutaneous disease, often induced by drugs. It is characterized by muco-cutaneous erythematous and purpuric lesions, flaccid blisters which erupt, causing large areas of denudation. The condition can involve the genitourinary, pulmonary and, gastrointestinal systems. Because of the associated high mortality rate early diagnosis and treatment are mandatory.
This article presents the case of a sixty-six years old male patient, known to have cirrhosis, chronic kidney failure, and diabetes mellitus. His current treatment included haemodialysis. He was hospitalized as an emergency to the Dermatology Department for erythemato-violaceous, purpuric patches and papules, with acral disposition, associated with rapidly spreading erosions of the oral, nasal and genital mucosa and the emergence of flaccid blisters which erupted quickly leaving large areas of denudation. Based on the clinical examination and laboratory investigations the patient was diagnosed with TEN, secondary to carbamazepine intake for encephalopathic phenomena. The continuous alteration in both kidney and liver function and electrolyte imbalance, required him to be transferred to the intensive care unit. Following pulse therapy with systemic corticosteroids, hydro-electrolytic re-equilibration, topical corticosteroid and antibiotics, there was a favourable resolution of TEN.
The case is of interest due to possible life-threatening cutaneous complications, including sepsis and significant fluid loss, in a patient with associated severe systemic pathology, highlighting the importance of early recognition of TEN, and the role of a multidisciplinary team in providing suitable treatment.
