ReviewThe prevalence of post traumatic stress disorder in survivors of ICU treatment: a systematic review.
To determine the prevalence of post traumatic stress disorder in survivors of intensive care treatment. ⋯ The true prevalence of PTSD and the optimum timing and method of PTSD assessment have not yet been determined in intensive care unit survivors. Deficiencies in design, methodology and reporting make interpretation and comparison of quoted prevalence rates difficult, and rigorous longitudinal studies are needed.

Clinical TrialInfluence of an acute increase in systemic vascular resistance on transpulmonary thermodilution-derived parameters in critically ill patients.
The transpulmonary thermodilution technique enables measurement of cardiac index (CI), intrathoracic blood volume (ITBV), global end-diastolic volume (GEDV), and extravascular lung water (EVLW). In this study, we analyzed the robustness of this technique during an acute increase in systemic vascular resistance (SVR). ⋯ An acute increase in SVR by increasing norepinephrine dosage results in a reversible increase in central blood volumes (ITBV, GEDV) as measured by transpulmonary thermodilution and supported by echocardiography.

Clinical TrialRenal arterial resistance in septic shock: effects of increasing mean arterial pressure with norepinephrine on the renal resistive index assessed with Doppler ultrasonography.
To determine the effects of increasing mean arterial pressure (MAP) on renal resistances assessed by Doppler ultrasonography in septic shock. ⋯ Doppler ultrasonography and resistive index measurements may help determine in each patient the optimal MAP for renal blood flow and may be a relevant end-point to titrate the hemodynamic treatment in septic shock.
