Use of a Modified Propofol Emulsion in Adults

This study has been completed.
Information provided by (Responsible Party):
B. Braun Melsungen AG Identifier:
First received: June 2, 2008
Last updated: January 2, 2012
Last verified: January 2012

The purpose of the study is to determine whether a modified propofol preparation shows any effect on the incidence of injection pain in adults undergoing elective surgery under general anesthesia.

Study hypothesis: The use of a modified propofol preparation will reduce the incidence of injection pain in the study group.

Condition Intervention Phase
Anesthesia Drug: Propofol Drug: Propofol 1% Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)

Further study details as provided by B. Braun Melsungen AG:

Primary Outcome Measures:
  • Incidence of Expression of Pain During Injection [ Time Frame: during first propofol bolus ]

Secondary Outcome Measures:
  • Further Assessment of Injection Pain [ Time Frame: during induction of anaesthesia and about 3 to 6 hours after end of anaesthesia ]

Enrollment: 100
Study Start Date: May 2008
Study Completion Date: September 2008
Primary Completion Date: September 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Modified propofol (Propofol 0.5%)
Drug: Propofol
Propofol (drug), intravenous, induction of anesthesia
Other Name: Modified propofol
Active Comparator: 2
Propofol 1%
Drug: Propofol 1%
Propofol (drug), intravenous, induction of anesthesia
Other Name: Propofol-Lipuro 1%

Detailed Description:
Pain on injection is a most frequently reported side effect associated with the use of propofol for induction of anesthesia. Various measures have been taken to reduce the pain on injection, e.g. administration of lidocaine or fentanyl prior to propofol administration, mixture of lidocaine and propofol as well as cooling of the emulsion. Although pain on injection had been reduced with some of the above mentioned methods, they may not be regarded as a satisfactory solution of the problem.
