I concur w/Ides. Warm as you can comfortably stand moist compresses multiple
times a day.
I've had [b]multiple[/b] short and long term IVs thru the years w/no problems. ONE time my entire upper arm did get warm, hot and hard. It that case it was most likely that the IV leaked out of the vein and under the skin.
I did have one
IV of improperly administered phenergan and toradol (not diluted enough and given too close to the IV set site) and ended up with not only superficial thrombophlebitis but also a blood clot in the axillary vein.
By the way: Toradol is becoming a VERY popular pain killer, as effective as morphine and not a .... narcotic? opiod? BUT it IS an [b]NSAID[/b] so ... be forewarned. It is also very irritating to the veins and MUST be properly diluted and administered a good distance from the IV set site.
