RODRIGUEZ-MIRANDA, Roberto; ROJAS-ZELEDON, Roy  and  TRISNOSKI-SUAREZ, Sandra. Propofol injection pain during sedation for colonoscopy: the role of venous catheterization site. Acta méd. costarric [online]. 2013, vol.55, n.1, pp.35-40. ISSN 0001-6002.

Background: The use of propofol has seen its greatest growth in the operating room and diagnostic centers. Pain associated with propofol injection is a common clinical issue. There have been many attempts to reduce pain, however, complete inhibition has not been achieved. Methods: Data was colected from patients sedated with propofol in the Endoscopy room at San Juan de Dios Hospital. The data obtained included the McCrirrick pain on propofol injection scale, demographic variables, caliber and location of venous catheters, as well as concomitant medications. The data was recorded by the treating anesthesiologist and reviewed by the researcher. Results: 58% of patients did not experience pain on propofol injection; 24,8% experienced mild pain, 12,8% moderate pain, and 1,7% severe pain. Statistically, the group of patients that received propofol through a venous catheter in the antecubital fossa, experienced less pain than those with a venous catheter placed in the hand, wrist, or anterior forearm. (p=0,006). Conclusion: The best way to reduce pain on propofol injection is to place the venous catheter in the antecubital fossa.

Keywords : Pain; propofol; sedation; colonoscopy.
