Impact of Intrathecal vs Intravenous Dexmedetomidine

Summary

The purpose of this research is to evaluate the impact of intrathecal dexmedetomidine in comparison with intravenous route in patients undergoing cesarean section. Alternate hypothesis :Dexmedetomidine is more effective when given intrathecally as adjuvant to bupivacaine in elective cesarean section Null Hypothesis: Dexmedetomidine is more effective when given intravenously as adjuvant to bupivacaine in elective cesarean section Study Design: Randomized controlled trial Study setting: Watim General Hospital Study Duration: 18 months after synopsis approval Sampling technique: Simple random sampling Sample Size: Using the Open Epi program, a sample size of 60 patients (30 in each group) was determined with a 95% confidence interval and 80% power. Inclusion Criteria: * Pregnant women between ages 18-35 years * Belongs to ASA class I or II * Subjected to elective C-section Exclusion Criteria: * Any history of gastrointestinal disease diabetes, thyroid disease, hypertension, obesity, or anemia * History of alcohol or drug abuse; * Major complications of pregnancy * Patients have contraindication to spinal block or allergic to any of drug
