Most tonsillectomies are performed as outpatient procedures in an ambu
latory care facility, The postoperative period can be protracted which
can cause dehydration and readmission to the hospital. Timely interve
ntion with home intravenous (IV) hydration can help prevent this compl
ication. A prospective clinical trial was designed to evaluate the ben
efit of home IV therapy after tonsillectomy. One hundred consecutive p
atients underwent tonsillectomy. Fifty returned home without home IV h
ydration and another 50 returned home with home IV hydration, Clinical
data were collected by the homecare nurse during the postoperative pe
riod. Comparison between these two groups showed that the patients wit
h home IV hydration had less morbidity. Daily assessment of the patien
t by telephone is the best screening method to determine the need for
IV hydration for the posttonsillectomy patient.
