Randomized Controlled Trial
Effects of Shenfu injection on sublingual microcirculation in septic shock patients: A randomized controlled trial.
Background and Objective: The optimization of macrocirculatory hemodynamics is recommended by current sepsis guidelines. However, microcirculatory dysfunction is considered the cause of severe sepsis. In the present study, we designed to verify whether the application of Shenfu injection (SFI) restores microcirculation, thereby improving tissue perfusion and inhibiting organ dysfunction, resulting in improved outcomes. ⋯ Importantly, the SFI group had a more favorable prognosis than the control group in terms of the APACHE-II score, SOFA score, duration of vasopressor administration, and length of EICU stay. However, the difference in mortality at day 28 was not statistically different between the SFI (15%, 3/20) and placebo (25%, 5/20) groups ( P = 0.693). Conclusions : Shenfu injection provided apparent effects in improving sublingual microcirculatory perfusion in patients with septic shock, and this protection may be related with the inhibition of endothelial dysfunction and vasodilatory effects.

Aim: Head and thorax elevation during cardiopulmonary resuscitation improves cerebral hemodynamics and ultimate neurological outcome after cardiac arrest. Its effect during extracorporeal cardiopulmonary resuscitation (E-CPR) is unknown. We tested whether this procedure could improve hemodynamics in swine treated by E-CPR. ⋯ Carotid blood flow and cerebral oxygen saturation were not significantly different among groups. Conclusion: During E-CPR, head and thorax elevation prevents ICP increase. Whether it could improve the ultimate neurological outcome in this situation deserves further investigation.
