Phenylephrine in Septic Shock
This study has been completed.
Sponsored by: University of Roma La Sapienza
Information provided by: University of Roma La Sapienza
ClinicalTrials.gov Identifier: NCT00639015
  Purpose

The present study was conducted as a prospective, randomized, controlled study to compare:

  • the effects of norepinephrine and phenylephrine on systemic and regional hemodynamics in patients with catecholamine-dependent septic shock
  • to test the hypothesis that norepinephrine may likewise better preserve hepatosplanchnic perfusion versus phenylephrine in patients suffering from septic shock

Study Type: Interventional
Study Design: Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Active Control, Parallel Assignment, Efficacy Study
Official Title: Phenylephrine Versus Norepinephrine in Septic Shock: Effects on Systemic and Regional Hemodynamics. A Randomized, Controlled, Trial

Further study details as provided by University of Roma La Sapienza:

Primary Outcome Measures:
  • Systemic and regional hemodynamics [ Time Frame: during the first 12 hours from the onset of septic shock ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Organ functions,adverse effects [ Time Frame: during the first 12 hours from the onset of septic shock ] [ Designated as safety issue: No ]

Enrollment: 32
Study Start Date: November 2007
Study Completion Date: June 2008
Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1: Experimental
Phenylephrine
Drug: Phenylephrine
Titrated phenylephrine to maintain mean arterial pressure between 65-75 mmHg over a period of 12 hours from the onset of septic shock.
2: Active Comparator
Norepinephrine
Drug: Norepinephrine
Titrated norepinephrine to maintain mean arterial pressure between 65-75 mmHg over a period of 12 hours from the onset of septic shock.

Detailed Description:

Thirty two septic shock patients requiring vasopressor support to maintain mean arterial pressure between 65 and 75 mmHg despite adequate volume resuscitation will be enrolled in the study. Patients will be randomly allocated to be treated with either a) titrated phenylephrine, b) titrated norepinephrine (control; each n = 16), to achieve a mean arterial pressure (MAP) between 65 and 75 mmHg, if necessary. Data from right heart catheterization, thermo-dye dilution catheter, gastric tonometry as well as data from organ function, will be obtained at baseline and after 12 hours.

  Eligibility

Ages Eligible for Study:   18 Years and older

Criteria

Inclusion Criteria:

Exclusion Criteria:

  • Pregnancy
  • Age < 18 years
  • Present cardiac dysfunction
  • Present or suspected acute mesenteric ischemia
