Background: International guidelines for management of septic shock recommend that dopamine or norepinephrine are preferable to epinephrine. However, no large comparative trial has yet been done. We aimed to compare the efficacy and safety of norepinephrine plus dobutamine (whenever needed) with those of epinephrine alone in septic shock.
Methods: This prospective, multicentre, randomised, double-blind study was done in 330 patients with septic shock admitted to one of 19 participating intensive care units in France. Participants were assigned to receive epinephrine (n=161) or norepinephrine plus dobutamine (n=169), which were titrated to maintain mean blood pressure at 70 mm Hg or more. The primary outcome was 28-day all-cause mortality. Analyses were by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00148278.
Findings: There were no patients lost to follow-up; one patient withdrew consent after 3 days. At day 28, there were 64 (40%) deaths in the epinephrine group and 58 (34%) deaths in the norepinephrine plus dobutamine group (p=0.31; relative risk 0.86, 95% CI 0.65-1.14). There was no significant difference between the two groups in mortality rates at discharge from intensive care (75 [47%] deaths vs 75 [44%] deaths, p=0.69), at hospital discharge (84 [52%] vs 82 [49%], p=0.51), and by day 90 (84 [52%] vs 85 [50%], p=0.73), time to haemodynamic success (log-rank p=0.67), time to vasopressor withdrawal (log-rank p=0.09), and time course of SOFA score. Rates of serious adverse events were also similar.
Interpretation: There is no evidence for a difference in efficacy and safety between epinephrine alone and norepinephrine plus dobutamine for the management of septic shock.

Acute cardiovascular disorders are incriminated in up to 33% of maternal deaths, and the presence of sickle cell anemia (SCA) aggravates the risk of peripartum complications. Herein, we present a 24-year-old Caribbean woman with known SCA who developed a vaso-occlusive crisis at 36 weeks of gestation that required emergency Cesarean section. In the early postpartum period, she experienced fever with rapid onset of acute respiratory distress in the context of COVID-19 infection that required tracheal intubation and mechanical ventilatory support with broad-spectrum antibiotics and blood exchange transfusion.

Sepsis often leads to vasoplegia and a hyperdynamic cardiac state, with treatment focused on restoring vascular tone. However, sepsis can also cause reversible myocardial dysfunction, particularly in the elderly with pre-existing heart conditions. The Surviving Sepsis Campaign Guidelines recommend using dobutamine with norepinephrine or epinephrine alone for patients with septic shock with cardiac dysfunction and persistent hypoperfusion despite adequate fluid resuscitation and stable blood pressure.

- Patients awaiting heart transplants often require colonoscopies due to bleeding or screening needs, but there's limited research on the safety of these procedures for individuals on inotropic medications or mechanical circulatory support.
- A study was conducted from 2015 to 2021 with 92 heart failure patients undergoing colonoscopy while on advanced heart failure therapies, such as inotropes or mechanical devices.
- Results indicated that the most common reason for colonoscopy was cancer screening, with significant findings including 8% of screening procedures revealing advanced adenomas and 17% of bleeding-related colonoscopies identifying sources needing intervention, but no major complications related to anesthesia were reported.

A 74-year-old woman presented with sudden dyspnea 22 h after orthopedic surgery. Echocardiography revealed significant right ventricular dilatation, suggesting the development of acute pulmonary embolism. However, contrast computed tomography showed no signs of pulmonary thromboembolism, leading to suspicion of fat embolism syndrome (FES).

Background: Patients with severe respiratory failure have high mortality and need various interventions. However, the impact of intensivists on treatment choices, patient outcomes, and optimal intensivist staffing patterns is unknown. In this study, we aimed to evaluate treatments and clinical outcomes for patients at board-certified intensive care training facilities compared with those at non-certified facilities.
