Randomized Controlled Trial Multicenter Study
Reducing pain by using venous blood gas instead of arterial blood gas (VEINART): a multicentre randomised controlled trial.
Venous sampling for blood gas analysis has been suggested as an alternative to arterial sampling in order to reduce pain. The main objective was to compare pain induced by venous and arterial sampling and to assess whether the type of sampling would affect clinical management or not. ⋯ Venous blood gas is less painful for patients than ABG in non-hypoxaemic patients. Venous blood gas should replace ABG in this setting.
