ABSTRACT

Acute anticholinesterase pesticide poisoning is a serious clinical problem, particularly in developing countries. Atropine is the most acceptable treatment for acute anticholinesterase poisoning. However, it only stops fluid production. Albuterol is a beta-2 receptor agonist that can increase fluid removal and speed the return of effective oxygen exchange. This study aims to evaluate the safety and efficacy of nebulized albuterol as an adjuvant therapy in patients with acute anticholinesterase poisoning. This stratified block randomized, single-blinded, placebo-controlled, parallel-group clinical trial was conducted between November 2020 and October 2021. It enrolled 80 patients with acute anticholinesterase pesticide poisoning who were admitted to Tanta University Poison Control Center. Patients were allocated into two groups (40 patients each). The strata were based on the severity of poisoning (moderate and severe). Patients in group I received 10 mg of nebulized albuterol. Group II received an equivalent volume of nebulized normal saline. Additionally, standard treatment was provided to both groups. Outcomes included oxygenation, mortality, need for endotracheal intubation and mechanical ventilation, hospital stay duration, time to atropinization, and total doses of atropine and oxime. We found insignificant differences in sociodemographics, exposure characteristics, clinical manifestations, or routine laboratory tests between the studied groups. The median values of oxygen saturation by pulse oximetry were 99% in the albuterol moderate toxicity group and 98% in the control moderate toxicity group. Albuterol significantly improved oxygen saturation in moderate intoxicated patients (P = 0.039). Therefore, nebulized albuterol is a safe drug. Moreover, it may improve oxygenation in acute anticholinesterase pesticide poisoning.

ABSTRACT

Background: Severe refractory hypotension and cardiogenic shock are the main contributors to death in acute aluminum phosphide (ALP) poisoning. Shock index (SI) and modified shock index (MSI) are easily obtained parameters that reflect shock at an early stage. Aim: This study aimed to evaluate the role of SI and MSI in the prediction of the severity and outcomes of acute ALP poisoned patients. Patients and methods: This cross sectional study was conducted on patients admitted to Tanta University Poison Control Centre with acute ALP poisoning from April 2022 to March 2023. Socio-demographics and toxicological data were taken, findings of clinical examination and laboratory investigations were recoded, SI was calculated by dividing heart rate over systolic blood pressure, and MSI was obtained by dividing heart rate over mean arterial pressure. Poisoning severity was assessed using poisoning severity score (PSS). Patients were divided into groups according to intensive care unit (ICU) admission and mortality. Results: The study enrolled 94 patients. The median values of SI and MSI were significantly higher in ICU-admitted patients and non-survivors rather than their comparable groups. Significant positive correlations were observed between each of SI and MSI and PSS. At cut-off >1.14, SI conveyed fair performance to predict ICU admission and mortality (AUC = 0.710 and 0.739, respectively). Similarly, MSI had fair performance to predict ICU admission (AUC = 0.731) and mortality (AUC = 0.744) at cut-off >1.47 and >1.5, respectively. Conclusion: Both SI and MSI could be considered simple bedside adjuncts to predict ICU admission and mortality in acute ALP poisoning.
