Ethical Dilemmas Faced by Military Health Personnel During High-Intensity Conflict: The Crucial Issue of Triage.

Russia's invasion of Ukraine has triggered the biggest conflict in Europe since the Second World War. It has forced countries to prepare for engagement on a massive scale, namely, a high-intensity war between nation states. A potential massive influx of wounded personnel risks saturating logistical supply chains and requires changes to not only medical care but also a paradigm shift. In this context, the principle of distributive justice is key. The aim is to save as many lives as possible through triage, which consists in "doing the greatest good for the greatest number." This idea is fundamental, as an emergency that has passed is no longer an emergency. However, international texts and treaties not only underline that the sole criterion for triage is clinical severity, but they also fail to take into account the patient's status (civilian, friend, and foe). In a high-intensity warfare situation, these texts, and the medical-surgical triage criteria they provide are insufficient, as caregivers may be required to make decisions based on the status of the patient. The need to make such choices could cause psychological suffering among military caregivers, as individuals are recurrently faced with difficult ethical dilemmas. One way to prevent this happening is to provide predeployment training in wartime medical ethics. The latter would include both instruction in international humanitarian law and practical simulations of clinical situations where the person is faced with an ethical dilemma.

Reactivation of Epstein-Barr virus among intensive care patients: a prospective observational study.

PURPOSE: Herpesvirus reactivation has been documented among patients in the intensive care unit (ICU) and is associated with increased morbidity and mortality, particularly for cytomegalovirus (CMV). Epstein-Barr virus (EBV) has been poorly studied despite >95% of the population being seropositive. Our preliminary study suggested an association between EBV reactivation and increased morbidity and mortality. This study aimed to investigate this association among patients admitted to the ICU. METHODS: In this multicenter prospective study, polymerase chain reaction was performed to quantify EBV in patients upon ICU admission and then twice a week during their stay. Follow-up was 90 days. RESULTS: The study included 129 patients; 70 (54.3%) had EBV reactivation. On day 90, there was no difference in mortality rates between patients with and without reactivation (25.7% vs 15.3%, p = 0.22). Patients with EBV reactivation at admission had increased mortality compared with those without reactivation and those with later reactivation. EBV reactivation was associated with increased morbidity. Patients with EBV reactivation had fewer ventilator-free days at day 28 than those without reactivation (18 [1-22] vs. 21 days [5-26], p = 0.037) and a higher incidence of acute respiratory distress syndrome (34.3% vs. 17%, p = 0.04), infections (92.9% vs. 78%, p = 0.03), and septic shock (58.6% vs. 32.2%, p = 0.004). More patients with EBV reactivation required renal replacement therapy (30% vs. 11.9%, p = 0.02). EBV reactivation was also associated with a more inflammatory immune profile. CONCLUSION: While EBV reactivation was not associated with increased 90-day mortality, it was associated with significantly increased morbidity.

An observational study of gastric content in women scheduled for cesarean section or operative hysteroscopy.

BACKGROUND: The estimation of gastric content in third trimester pregnant women has already been studied, conclusions remain contradictory. The aim of this study was to compare gastric content in pregnant and non-pregnant women using gastric ultrasound. We performed an observational two-center study of women scheduled for a cesarean section (CS group) and of non-pregnant women scheduled for hysteroscopy (HS group). METHODS: Ultrasound evaluation was performed before surgery with measurement of antral cross-sectional area (CSA) in the semi-recumbent position (SRP), primary outcome, and in the right lateral position (RLD). Gastric fluid volume (GFV) was calculated. Results are expressed as medians (25th and 75th percentiles). Perlas Score was evaluated and expressed as number (percentage). RESULTS: Sixty patients in the CS group and 64 in the HS group were analyzed. Antral CSA (SRP) was greater in the CS group (350 mm2 [236-415] vs. 247 mm2 [180-318]; P=0.001). Antral CSA (RLD) was also significantly greater in the CS group (P=0.027). GFV was not different between groups whether expressed in absolute value (P=0.516) or relative to weight (P=0.946) mL.kg-1. Perlas Score repartition was similar in both groups (P=0.860). Kappa coefficients of concordance between CSA, GFV and Perlas Score were slight or at best fair. CONCLUSIONS: Our study confirmed that antral CSA is increased among pregnant women and outlined that antral CSA should not be used alone in the decision-making process especially when the results of indicators (antral CSA, GFV, and Perlas Grading Score) are discordant.

Relationship between creatine kinase and liver enzymes in war wounded with rhabdomyolysis.

BACKGROUND: Rhabdomyolysis is a frequent complication in war wounded. Its complex pathophysiology suggests that it not only affects kidneys but also other organs such as the liver. The aim of this study was to evaluate the relationship between creatine kinase (CK) and liver enzymes in war wounded with rhabdomyolysis. METHODS: War wounded admitted to the intensive care unit of Percy Military Hospital between 2009 and 2017 with a rhabdomyolysis (CK peak >1,000 U/L) were included. They were divided in two groups: mild (CK peak <10,000 U/L) and severe rhabdomyolysis (CK peak ≥10,000 U/L). Demographic characteristics, peaks in transaminases, alkaline phosphatase (ALP), bilirubin, and CK were recorded. Mann Whitney-U test and, Fisher's exact test were used as appropriate. A Pearson's correlation test was used to determine the correlation between CK and liver enzymes after a log-normal transformation of the data. RESULTS: Fifty-one patients were included (31 in the mild and 20 in the severe rhabdomyolysis group). Patients in the severe rhabdomyolysis group were more likely victims of explosions (85% vs 39%, p = 0.003). The transaminases peak was significantly higher in the severe rhabdomyolysis group (median AST peak 398 (270-944) vs 91 (63-157) U/L, p <0.0001, and median ALT peak 106 (77-235) vs 45 (34-71) U/L, p<0.0001). Bilirubin and ALP were higher in the severe rhabdomyolysis group (39 (25-49) vs 14(11-23) U/L, p = 0.0031 and 84 (55-170) vs 52 (39-85) U/L, p = 0.0063, respectively). We found a significant positive linear correlation between CK and ALT (r = 0.73, p<0.0001), AST (r = 0.89, p<0.0001), ALP (r = 0.41, p = 0.0035), and bilirubin (r = 0.37, p = 0.0083). CONCLUSION: We found a statistically significant positive correlation between CK and liver enzymes in rhabdomyolysis war wounded, indicating that hepatic damage occurs when rhabdomyolysis is severe and associated with elevated bilirubin and ALP. Further studies are needed to confirm this phenomenon and elucidate the pathophysiological mechanism. LEVEL OF EVIDENCE: IV STUDY TYPE: Diagnostic.
