Clinical Trial Summary

This trial aims to evaluate if cryospray can reduce pain during intravenous cannulation in elective surgery compared to a placebo spray.

Description:

Venous cannulation is a common practice in the health care system. Before any procedure, intravenous access is always placed before induction of any anaesthesia. For many patients placement of a venous catheter is associated with pain and discomfort. Any quick and easy reduction in pain during the procedure is important for patients. Cryospray has been described as an easy-to-use supplement of analgesia to alleviate pain during intravenous access. Cryospray has been shown to reduce pain in venous cannulation in the emergency setting but not in the elective setting. A search in the literature reveals 2 recent metanalyses reporting 8 included trials and 11 included trials, respectively. Both metanalyses call for further research in relation to patients' satisfaction. By randomizing patients to either cryospray or placebo before venous cannulation, we hypothesize that cryospray reduces pain during venous cannulation compared to placebo.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Discomfort from puncture site at discharge from recovery	After discharge from the recovery room patients is asked for any discomfort at the puncture site. If yes: pain, numbness, burning or cold feeling. All positive values rated on the numeric rating scale (0-10).	up to 24 hours after discharge from recovery room
Primary	Patients reported pain from the puncture site	After vein puncture is completed patients is asked on a scale from 0-10 to indicate pain during vein canulation (zero no pain, 10 worst possible pain)	immediately after completion of vein canulation
Secondary	Difficulty in placement of intravenous line	After vein puncture is completed the operator is asked to the difficulty in placement of the venous line (0-10, zero very easy and ten very difficult).	immediately after completion of vein canulation
Secondary	Number of successful placements of venous line at first attempt	After vein puncture is completed it is indicated wether or not it was successful in first attempt.	immediately after completion of vein canulation
