Brief Summary:
We hypothesized that the increase in MAP from 65 mmHg to patients' usual level improved sublingual microcirculation.

Condition or disease Intervention/treatment Phase
Septic Shock Other: NE Not Applicable

Detailed Description:
The effect of mean arterial pressure (MAP) titration to higher level on microcirculation in septic shock patients with previous hypertension remains unknown. Our goal was to assess the effect of MAP titration to patients' usual level on microcirculation in septic shock patients with previous hypertension. We hypothesized that the increase in MAP from 65 mmHg to patients' usual level improved sublingual microcirculation.

Arm Intervention/treatment
Experimental: NE group
Adjust NE dose to titrate MAP to usual level regardless of fluid responsiveness when after EGDT.
Other: NE

Primary Outcome Measures :
  1. Mean Arterial Pressure [ Time Frame: Target MAP stabilization for 30 min ]

    As chronic hypertensive patients were supposed to have undergone more blood pressure measurements in daily life than non-hypertensive ones, the averaged MAP acquired from patients' physical examination records of the last two years was registered and assumed as patients' usual level of MAP and target MAP. If patients' medical records were incomplete, a detailed enquiry about the target MAP to their next kin was performed.

    After stabilization for 30 min, basal measurements including hemodynamic and microcirculatory measurements were taken, 20 min apart, the NE doses were increased to titrate MAP to the target level. Patients were allowed to stabilize for 30 min before taking new measurements.

Secondary Outcome Measures :
  1. Perfused Vessel Density [ Time Frame: Target MAP stabilization for 30 min ]
    Increasing MAP from 65 mm Hg to target level. The sublingual microcirculation was measured by sidestream dark field, including the parameters of perfused vessel density
