ABSTRACT
Background and objectives: Thyroid disorders are among the common endocrine disorders in pregnant women. Our aim was to know the prevalence of thyroid dysfunction in pregnancy and its impact on obstetric outcome in Indian population. Materials and methods: It was a prospective study which involved screening of 1000 pregnant women coming to routine antenatal check-up in first trimester. TSH level was estimated. If it was deranged, then FT3 and FT4 levels estimated. Patients were managed accordingly and followed till delivery. Their obstetric and perinatal outcomes were noted. Results: Prevalence of thyroid dysfunction was high in this study, with subclinical hypothyroidism in (6.9%) and overt hypothyroidism in (3.4%) women. Overt hypothyroids were prone to have preeclampsia preeclampsia (14.7%), abruptio placenta (2.9%), preterm delivery (8.8%), abortion (11.8%), IUGR (11.7%), LBW (11.7%), still birth (2.9%), which is comparable to other studies. Overt hyperthyroids were prone to have miscarriage (66.7%) which was significantly high. Conclusion: Prevalence of thyroid disorders, especially subclinical hypothyroidism (6.9%) and overt hypothyroidism (3.4%) was high. Significant adverse effects on maternal and fetal outcome were seen emphasizing the importance of routine antenatal thyroid screening
ABSTRACT
Aim: To evaluate the effects of Dexmedetomidine to reduce the intra ocular pressure and sedation in day care cataract surgeries. Materials and methods: This study was conducted in 50 patients of either sex, belonging to 40 – 60 years of age, ASA grade I and II admitted for cataract surgeries. Patients were randomized into two groups of 25 each. Group D received 1 mcg/mg of Dexmedetomidine as IM route, Group P received placebo as IM and intra ocular pressure changes, hemodynamic parameters, sedation levels and SPO2, anxiolysis and pain were monitored. Results: There was a statistically significant difference in group D before and after premedication in terms of intra ocular pressure reduction. This was not seen in placebo group. Systolic blood pressure, diastolic blood pressure and heart rate in the study was a statistically difference in group D before and after premedication. There was no statistically significant difference in group P before and after premedication. There was a statistically significant difference (P<0.05) between the group D and group P in terms of sedation. Oxygen saturation observed in group D and group P at intervals of 0, 10, 20, 30, 40, 50, 60 min showed no statistical significance (P>0.05). There was a statistically significant D.

IAIM, 2016; 3(2): 60-68. Page 61 difference (P<0.05) between the group D and group P in terms of pain relief and anxiety after premedication. Conclusion: Results suggested that Dexmedetomidine produces sedation and a reduction of intraocular pressure with minimal hemodynamic side effects when given intramuscularly as premedication before cataract surgery under regional anesthesia.
