AI Article Synopsis
- * A post hoc analysis of the SEPSISPAM trial included 532 mechanically ventilated and sedated patients, assessing their levels of arousal using the Richmond Agitation and Sedation Scale (RASS).
- * Results showed that patients in the high-target MAP group had significantly higher arousal levels at days 2, 4, and 5 compared to those in the low-target group, indicating potential benefits of higher MAP goals in improving patient responsiveness.
Article Abstract
Background: It is unknown whether the recommended mean arterial pressure (MAP) target of 65 mmHg during initial resuscitation of septic shock is sufficient to maintain cerebral perfusion. Thus, we tested the hypothesis that a higher MAP target in patients with septic shock may improve level of arousal.
Methods: We performed a post hoc exploratory analysis of the SEPSISPAM trial, which assessed the effect of a "high-target" level of MAP (80-85 mmHg) versus the recommended "low-target" MAP (65-70 mm Hg) on mortality in patients with septic shock. Among the 776 patients originally recruited in SEPSISPAM trial, we selected those who were mechanically ventilated and sedated and with available evaluation of arousal level assessed by the Richmond Agitation and Sedation Scale (RASS).
Results: We restricted our analysis to the period in which patients were treated with vasoactive drugs. Cumulative sedative drugs were assessed daily. A total of 532 patients were included in this study: 253 (47.6%) in the low-target group and 279 (52.4%) in the high-target group. Daily cumulative sedative drugs were similar in both groups. Compared to the low-target group, minimal and maximal RASS were significantly higher in the high-target group at day 2, 4 and 5. Furthermore, in order to consider the fact that multiple measures were done for each patient and to consider the global effect of time on these measures, we used a mixed linear regression and multivariate models: we confirmed that maximal RASS values were significantly higher in the high-target group.
Conclusion: In patients with septic shock who were mechanically ventilated and sedated, resuscitation with MAP target between 80 and 85 mmHg was associated with higher arousal level as compared to a MAP target between 65 and 70 mmHg.

Sepsis, a condition characterized by a dysregulated host response to infection, can progress to septic shock and lead to various complications. The present study aimed to identify risk factors for the early clinical identification of sepsis patients at heightened risk of complications. In the present study, a total of 383 hospitalized patients with sepsis and positive blood cultures were enrolled.

Sepsis and septic shock are major complications of febrile neutropenia (FN) in pediatric patients with cancer (PPCs). The aim of the present study was to determine the association of vitamin D (VD) and cathelicidin levels with sepsis and septic shock in PPCs with FN. A prospective cohort of PPCs with FN who had previously received cytotoxic chemotherapy was analyzed.

Background: Identifying risk factors for mortality in patients with bacteremia (SAB) is crucial due to its high fatality. However, data on risk factors for infection-attributable deaths considering competing risk events such as non-infection-attributable deaths remain limited. We performed a competing risk analysis to elucidate risk factors associated with 30-day infection-attributable mortality in a large cohort of patients with SAB.
