Acute poisoning is a frequent cause of admission to emergency departments and intensive care units, as it is considered as an important medical emergency requiring early diagnosis and rapid initiation of therapy. The aim of the present study was to assess characteristics, and outcomes of acutely intoxicated patients who were admitted to ICU. Also, design a scoring system regarding priority for ICU admission. The present study was carried out on 40 patients who were admitted to intensive care unit of El Mansoura General Hospitals-Egypt during a period of 6 months. Personal, toxicological, and medical histories, clinical examination and routine investigations were recorded for each patient. At discharge; all patients were reassessed for determination of patients' outcome. The patients were mostly females, single; student aged less than 30 years and from rural areas. The majority of the patients (72.5%) were recovered, 22.5% were died and 5% were referred to hyperbaric oxygen therapy units after carbon monoxide intoxication. Many patients were presented by constricted pupil (45%), respiratory depression (42.5%), altered mental status (42.5%), tachycardia (47.5%), and nausea & vomiting (75%). The highest numbers of cases were poisoned by medicinal drugs (40%) followed by agricultural chemicals (35%). Statistically significant difference between occupation, toxicological amount & frequency, pulse rate, Glasgow coma score, PH & PCO2 and type of poison (zinc phosphide) and patient outcomes was observed. Although many of the patients' characteristics were significantly associated with patient outcome yet none of them was considered significant predictors for death. So, the suggested scoring system depended mainly on clinical data and simple rapid investigation that may be helpful for rapid assessment of the patients after further validation. We recommend the presence of a channel of communication between the general care centers and the poison control centers for consultation about the protocol of treatment of poisoned patients. Nationwide, a mechanism of communication between the poison centers must be done to benefit from the different expertise and to make a uniform protocol for treatment of poisoned cases to decrease the mortality rate and the burden on hospitals resources.
Background Patients with acute myocardial infarction (AMI) especially those with large MI (myocardial infarction) as identified by ST elevation in multiple contiguous ECG leads or anterior MI, may suffer significant myocardial damage leading to impaired wall motion and contractility which may lead to the formation of left ventricular thrombus (LVT) in the patient. This study was aimed to establish the incidence of LV thrombus and determine the predictors associated with the formation of LV thrombus in patients with AMI. Methods This retrospective study was held at the only cardiothoracic centre of Makkah, which provides tertiary level cardiac services. A total of 3084 consecutive patients with acute MI between 2016 and 2019 were identified and divided into two groups i.e. group I (with LVT) and group II (without LVT). The case notes, echocardiography data and cardiac catheterization lab records were reviewed to identify patients with LV thrombus. Regression analysis was employed to evaluate the predictors responsible for the formation of LV thrombus. Results The overall incidence for LV thrombus was determined as 8.4% (n = 260/3084), while in the subpopulation of pilgrims, it was 8.2% (83/1001). Mean age for patients with and without LVT was 54 ± 11 years vs 56 ± 12 years (p < 0.003), respectively. There was no significant difference between the two groups with respect to gender, diabetes, hypertension, smoking, Arabic speaking or BMI>30. Coronary thrombus aspiration was utilized in 17% vs 12% (p < 0.023) patients with LVT and without LVT, respectively. It was observed that the patients with cardiac arrest tend to develop more LVT i.e. 8.5% vs 5.2% (p < 0.033). However, LV thrombus formation was significantly associated with anterior STEMI with incidence of LVT reaching 13.4% and low ejection fraction (all MI types) i-e. 32 ± 9% vs 42 ± 11%, with p < 0.000 for both independent predictors. Conclusions LV thrombus is a relatively common occurrence in patients with acute MI, especially those with anterior STEMI and low ejection fraction<30%. Appropriate imaging studies are required for all acute MI patients in order to ascertain the presence or absence of LV thrombus as it has major influence on further management.
