Wl. Hennrikus et al., Prevalence of positive preoperative pregnancy testing in teenagers scheduled for orthopedic surgery, J PED ORTH, 21(5), 2001, pp. 677-679
The pregnancy status of female teenagers presenting for orthopaedic surgery
is often unknown. Anesthetics may have teratogenic or abortive effects. Th
e authors report the results of a screening program for unrecognized pregna
ncy in 532 female teenagers presenting for orthopaedic surgery. Five patien
ts with a positive urine human chorionic gonadotropin test were identified,
for a prevalence of 1 positive result in 106 patients tested (0.9%). Surge
ry was cancelled in each case.
