AI Article Synopsis

  • A 32-year-old woman with severe asthma experienced respiratory failure after receiving two doses of metoclopramide for nausea related to sepsis.
  • Her respiratory distress began after the first dose, but she required intubation following the second dose, raising concerns about anaphylaxis or asthma exacerbation.
  • The case suggests that metoclopramide may pose serious risks for patients with existing lung issues, highlighting the need for caution in its use.

Article Abstract

Objective: To report a case of respiratory failure, possibly due to anaphylaxis or asthma exacerbation, following the administration of metoclopramide.

Case Summary: A 32-year-old white woman with a history of severe asthma and short-bowel syndrome was admitted for Hickman catheter line sepsis. Two doses of oral metoclopramide 10 mg in solution were administered for nausea and vomiting. Transient dyspnea followed the first dose of metoclopramide, but respiratory failure requiring intubation followed the second dose.

Discussion: Respiratory failure has been reported with metoclopramide-induced movement disorders. Three other cases of respiratory failure from anaphylaxis or asthma exacerbation following metoclopramide administration have been reported. Respiratory failure in our patient may be due to anaphylaxis or bronchoconstriction from metoclopramide-induced cholinergic activity of the vagus nerve, possibly through inhibition of acetylcholinesterase.

Conclusions: The use of metoclopramide in patients with pulmonary dysfunction may warrant caution.

Objective: Aim: To determine the influence of maternal and neonatal variants of the eNOS (G894T, rs1799983) and IL1B (C3953T, rs1143634) genes and their intergenic interactions on the development of HIE in newborns.

Patients And Methods: Materials and Methods: The study included a cohort of 105 newborns and their 99 mothers. Determination of variants of the genes eNOS (G894T, rs1799983) and IL1B (C3953T, rs1143634) was carried out for the patients of study groups.

Fulminant myocarditis (FM) is an acute, diffuse inflammatory myocardial disease characterized by abrupt onset and extremely rapid progression. Patients typically exhibit haemodynamic abnormalities that may lead to respiratory failure, liver and renal failure, and subsequent coagulopathy. Collectively, these complications significantly increase the risk of early mortality.

Background: Awake prone positioning (APP) can reportedly reduce the need for intubation and help improve prognosis of patients with acute hypoxemic respiratory failure (AHRF) infected with COVID-19. However, its physiological mechanism remains unclear. In this study, we evaluated the effect of APP on lung ventilation in patients with moderate-to-severe AHRF to better understand the effects on ventilation distribution and to prevent intubation in non-intubated patients.

Background: Receptor-interacting protein kinase 1 (RIPK1), a serine/threonine protein kinase, is mainly activated by pro-inflammatory cytokines and pathogens, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and its activation could result in apoptosis, necroptosis, or inflammation. This study was conducted to evaluate the safety and efficacy of a potent and selective inhibitor of RIPK1, SIR1-365, in hospitalized patients with severe coronavirus disease 2019 (COVID-19).

Methods: This multicenter, randomized, double-blind, phase 1b study screened patients from December 18, 2020 until November 27, 2021.

Background: Cancer patients who are exposed to sepsis and had previous chemotherapy may have increased severity. Among chemotherapeutic agents, anthracyclines have been associated with cardiac toxicity. Like other chemotherapeutic agents, they may cause endothelial toxicity.
