Use of night vision goggles and low-level light source in obtaining intravenous access in tactical conditions of darkness.
OBJECTIVE
The tactical environment of the nighttime battlefield precludes the use of white light to perform medical procedures. This study sought differences between two alternatives to white light used to facilitate intravenous access. A comparison was made between night vision goggles (NVG) and a low level light source (Fingerlite).


METHODS
Fifty-eight volunteers were paired. Each member of the pair attempted intravenous access on his or her partner in darkness using both techniques. One attempt per method was allowed. Success was confirmed by the free flow of blood from the catheter.


RESULTS
Of the 58 attempts using NVG, 32 were successful and 26 failed. In the Fingerlite group, there were 46 successful attempts and 12 failures. These differences reached statistical significance (p < 0.02).


CONCLUSIONS
This study suggests that in conditions requiring darkness, a Fingerlite offers a clinical advantage over NVG in obtaining intravenous access.
