Introduction: The utilization of extracorporeal membrane oxygenation (ECMO) in adult patients experiencing septic shock is a subject of ongoing debate within the medical community. This study aims to comprehensively address this issue through a systematic review conducted in accordance with the PRISMA guidelines.
Aim of Study: The primary objective of this study is to assess the outcomes of ECMO utilization in adult patients diagnosed with septic shock, thereby providing insights into the potential benefits and uncertainties associated with this treatment modality.
Materials and Methods: Our research encompassed a thorough search across electronic databases for relevant English-language articles published up until April 2023. The inclusion criteria were based on studies reporting on ECMO usage in adult patients with septic shock. Among the eligible studies meeting these criteria, a total of eleven were included in our analysis, involving a cohort of 512 patients. The mean age of the participants was 53.4 years, with 67.38% being male.
Results: In the pooled analysis, the mean survival rate following ECMO treatment was found to vary significantly across different ECMO modalities. Patients receiving venovenous-ECMO (VV-ECMO) and veno-venous-arterial ECMO (VVA-ECMO) demonstrated higher survival rates (44.5% and 44.4%, respectively) compared to those receiving venoarterial-ECMO (VA-ECMO) at 25% (p<0.05). A chi-square test of independence indicated that the type of ECMO was a significant predictor of survival (χ²(2) = 6.63, p=0.036). Additionally, patients with septic shock stemming from respiratory failure demonstrated survival rates ranging from 39% to 70%. Predictors of mortality were identified as older age and the necessity for cardiopulmonary resuscitation (CPR).
Conclusions: In septic shock patients, ECMO outcomes align with established indications like respiratory and cardiogenic shock. VV-ECMO and VVA-ECMO suggest better prognoses, though the optimal mode remains uncertain. Patient selection should weigh age and CPR need. Further research is vital to determine ECMO’s best approach for this population.

Introduction: There is limited data on the impact of extracorporeal membrane oxygenation (ECMO) on pulmonary physiology and imaging in adult patients. The current study sought to evaluate the serial changes in oxygenation and pulmonary opacities after ECMO initiation.
Methods: Records of patients started on veno-venous, or veno-arterial ECMO were reviewed (n=33; mean (SD): age 50(16) years; Male: Female 20:13). Clinical and laboratory variables before and after ECMO, including daily PaO2 to FiO2 ratio (PFR), were recorded. Daily chest radiographs (CXR) were prospectively appraised in a blinded fashion and scored for the extent and severity of opacities using an objective scoring system.
Results: ECMO was associated with impaired oxygenation as reflected by the drop in median PFR from 101 (interquartile range, IQR: 63-151) at the initiation of ECMO to a post-ECMO trough of 74 (IQR: 56-98) on post-ECMO day 5. However, the difference was not statistically significant. The appraisal of daily CXR revealed progressively worsening opacities, as reflected by a significant increase in the opacity score (Wilk’s Lambda statistic 7.59, p=0.001). During the post-ECMO period, a >10% increase in the opacity score was recorded in 93.9% of patients. There was a negative association between PFR and opacity scores, with an average one-unit decrease in the PFR corresponding to a +0.010 increase in the opacity score (95% confidence interval: 0.002 to 0.019, p-value=0.0162). The median opacity score on each day after ECMO initiation remained significantly higher than the pre-ECMO score. The most significant increase in the opacity score (9, IQR: -8 to 16) was noted on radiographs between pre-ECMO and forty-eight hours post-ECMO. The severity of deteriorating oxygenation or pulmonary opacities was not associated with hospital survival.
Conclusions: The use of ECMO is associated with an increase in bilateral opacities and a deterioration in oxygenation that starts early and peaks around 48 hours after ECMO initiation.

Very few reports exist on serious cardiac complications associated with intake of serotonin-noradrenaline reuptake inhibitors. This paper describes and discusses the case of a patient who ingested a dose of 17.5 g venlafaxine. She developed a full serotonergic syndrome leading to multi-organ failure, including refractory cardiovascular shock, which was managed by early implantation of an extracorporeal life support (ECLS) system as a bridging strategy. This intervention was successful and resulted in full recovery of the patient.
