A novel approach to hyperemesis gravidarum: evaluation by a visual analogue scale score and treatment with transdermal clonidine
Objective A preliminary report on the symptomatic effect of clonidine in severe hyperemesis gravidarum (HG). Design Observational. Settting Hospital based: Ospedale Sant'Anna, Torino, Italy. Population Twelve pregnant women, 8–16 weeks, affected by severe, refractory HG. Methods Assessment by two clinical score indexes: Pregnancy Unique Quantification of Emesis (PUQE) score and a Visual Analogue Scale (VAS) 5-item questionnaire, filled out daily, to detect subjective improvement or worsening of symptoms. Main outcome measures PUQE score and VAS score before and after transdermal clonidine treatment. Results We found substantial improvement of symptoms and severity score indexes after four and 14 days. The comparison of pretreatment and post-treatment scores shows a significant statistical difference P < 0.0001. Conclusion Transdermal clonidine may be considered as a treatment for resistant severe HG.
