Role of intravenous lipid emulsions in the management of calcium channel blocker and β-blocker overdose: 3 years experience of a university hospital

Abstract Objectives: The objective of this study was to assess the efficacy of lipid emulsion as antidotal therapy in severe calcium channel blocker (CCB) and β-blocker (BB) intoxications. Patients and methods: This is a retrospective study in which we have summarized data of patients who were admitted to a university-based emergency department in a period of 3 years and were given intravenous lipid emulsion (ILE) to manage cardiogenic shock due to CCB and BB overdose. Results: We identified 15 patients who received ILE therapy for CCB and BB toxicity. Hospitalization durations variated between 3 and 33 days (mean 7.46 ± 7.41 days). Drug exposures included CCBs (n = 8, 53.3%), CCBs and paracetamol (n = 1, 6.6%), and BBs (n = 6, 40%). ILE therapy was effective in 12 patients (80%). Three patients (20%) had resistant hypotension, one of whom progressed to pulmonary edema. Adverse effects of ILE therapy were seen in three patients (20%). Two patients underwent mechanical ventilation. Two patients developed hypoxic ischemic encephalopathy, one patient died, and 14 patients (93.3%) were discharged from hospital. Conclusion: There was 93.3% survival in patients receiving ILE for drug-induced cardiovascular collapse. Clinically significant adverse effects were uncommon. We suggest ILE administration for the treatment of cardiogenic shock due to CCB and BB overdose.

Ultrasound Accelerated Thrombolysis May Be an Effective and Safe Treatment Modality for Intermediate Risk/Submassive Pulmonary Embolism

Pulmonary embolism (PE) is a potentially life-threatening condition and the fact that 90% of PE originate from lower limb veins highlights the significance of early detection and treatment of deep vein thrombosis. Massive/high risk PE involving circulatory collapse or systemic arterial hypotension is associated with an early mortality rate of approximately 50%, in part from right ventricular (RV) failure. Intermediate risk/submassive PE, on the other hand, is defined as PE-related RV dysfunction, troponin and/or B-type natriuretic peptide elevation despite normal arterial pressure. Without prompt treatment, patients with intermediate risk PE may progress to the massive category with a potentially fatal outcome. In patients with PE and right ventricular dysfunction (RVD), in hospital mortality ranges from 5% to 17%, significantly higher than in patients without RVD.

Therapeutic plasma exchange in poisoning: 8 years' experience of a university hospital

INTRODUCTION AND AIM This study examined the extracorporeal methods for the elimination of toxic substances in poisoned patients that are used by clinicians taking care of such patients. Here we present our experience in the use of therapeutic plasma exchange (TPE). To the best of our knowledge, this is the largest number of poisoning cases ever reported in a study. PATIENTS AND METHODS This is a retrospective study conducted at the Çukurova University Faculty of Medicine, Department of Emergency Medicine, with the permission of the ethical committee of the medical faculty. The study includes patients who had undergone TPE because of poisoning between January 2007 and May 2015. We summarize the clinical data and outcomes of the patients with available files. RESULTS A total of 36 cases among the 42 patients who underwent TPE in this 8-year period were included in the study. More than 20 identified toxic substances, most of which were pesticides, were found to be the causes of poisoning. Twenty-three healthy discharges and 12 deaths are discussed in the study. CONCLUSION We believe that our study reports the largest ever number of poisoning cases treated with TPE in the literature. When applicable, TPE may be a promising extracorporeal elimination and treatment technique in poisoned patients when performed in selected cases.

Utilization of plasmapheresis in the management of bismuth intoxication with acute renal failure

A 34-year-old female patient who ingested 2400 mg bismuth subcitrate in a suicide attempt was brought to the emergency department. She had mild encephalopathy and acute renal failure on admission. One session of plasmapheresis was performed to remove bismuth, and needed three sessions of hemodialysis and was discharged on the 24th day of hospitalization with the recovery of the renal function.

Prognostic factors determining morbidity and mortality in organophosphate poisoning

Objective: Our aim in this retrospective study was to determine the factors affecting poor prognosis and mortality of organophosphate (OP) poisoning by reviewing patient data. We also reviewed present knowledge to make conclusions on certain longstanding debates in light of the literature. Methods: In this retrospective descriptive study, patients who were admitted to and hospitalized in the emergency department (ED) or intensive care unit (ICU) of a university hospital with the diagnosis of OP poisoning between December 2010 and December 2015 were evaluated. All the data were obtained from electronic and manual patient files. A total of 80 patients were included in the study. Results: The mean age of the study patients was 32.4±15.0 (13-94). Forty-nine (61.2%) patients were female. Twenty-two (27.5%) patients were seriously poisoned and needed mechanical ventilation (MV) support. Low pseudocholinesterase (PChE), high creatinine (Cr), low Glasgow Coma Scale (GCS) scores and long hospitalization durations were all found to be poor prognostics in MV patients. Low PChE and high Cr levels were found to be independent predictors of the hospitalization duration and high Cr was found to be an independent predictor of the intubation duration of MV patients in regression analyses. Ten (45.5%) of the MV patients were unresponsive to medical treatment and Therapeutic plasma exchange (TPE) was performed. Seven patients were discharged healthy. Three patients with low PChE levels and comorbidities died. Conclusions: Prolongation of respiratory depression necessitating MV support, comorbidities, long hospital stay, elevated creatinine, low GCS scores and low PcHE levels without regeneration in the first 48 hours of admission are all found to be poor prognostic factors for organophosphate (OP) poisoning.

Utilization of plasmapheresis for organophosphate intoxication: A case report

Organophosphate (OP) compounds are extremely toxic chemicals that may be absorbed via skin, conjunctiva, gastrointestinal and respiratory systems. Treatment of OP poisoning is a critical and aggressive process which includes decontamination, antidote administration (atropin and oximes), mechanical ventilation support and extracorporeal elimination procedures if needed. Here we present a young female patient who was unintentionally poisoned by an OP (trichlorfon) after using it to moisture her skin. The importance of this patient is the dermal disease that makes her unprotective to dermal exposure of chemicals and application of plasmapheresis to treat her poisoning.

Poisoned after Dinner: Dolma with Datura Stramonium.

SUMMARY Datura stramonium, which is also known as Thorn Apple or Jimson Weed, is an alkaloid containing plant that is entirely toxic. The active toxic constituents of the plant are atropine, scopolamine and hyoscyamine. It has been abused worldwide for hundreds of years because of its hallucinogenic properties. Previous reports have shown that herbal medication overdose and accidental food contamination are ways it can cause poisoning. Herein we present a family that had three of its members poisoned after eating a traditional meal “dolma” made of datura flowers. None had fatal complications and all were discharged healthy. Datura stromonium may be used accidentally as a food ingredient. Since its poisonous effects are not known, people should be informed and warned about the effects of this plant.

Necrotizing arachnidism: Diagnosing with inspection in insect bites

Early diagnose and treatment in spider bites of Loxosceles species is extremely important in prevention of systemic and local complications. There is not any specific laboratory test or diagnostic clue except lesions morphology and patient anamnesis. Thus inspection in physical examination and clinical follow-up of such lesions should be remembered. Here, we present two cases of suspected insect bites, one of whom was diagnosed as necrotizing arachnidism due to spider bite.
