Abstract
Objectives: To determine the impact of intravenous Dexmedetomidine (Dex) administered perioperatively on stress response markers in patients undergoing ENT surgeries.
Methods: This randomized interventional study was conducted at POFs Hospital and NUMS affiliated WMC, Wah Cantt, in collaboration with IIMC Rawalpindi, Pakistan, from October 2021 to April 2022. One hundred patients aged between 15-60 years, after satisfying the inclusion standards were randomly divided into two groups C and D. Group-C (n=50) received normal saline in addition to the standard anesthesia protocol. The intervention Group-D (n=50) was administered 1µg/kg dexmedetomidine hydrochloride intravenously over 10 minutes just before the induction followed 0.5μg/kg/hr as maintenance dose till the end of surgery. Serum inflammatory biomarkers (interleukins-6, TNF-α and cortisol) were measured in blood samples in both groups, taken at 0 (T0), 30 minutes(T1), and two hours (T2) time intervals and analyzed by using Enzyme-linked immunosorbent assay (ELISA). Data was statistically analyzed using SPSS 23.
Results: The patients receiving Dex showed marked decrease in serum levels of cortisol, TNF- α and interleukins-6, from 139.73 to10.18, 99.51 to 0.96 and 85.09 to 0.96 respectively. Comparison between C and D groups revealed significant differences (p≤0.05) in these serum biomarkers.
Conclusions: In the present study, intravenous Dex suppressed the intraoperative rise in levels of cytokine secretion and enhanced smooth recovery with no incidence of nausea and vomiting. These effects could be attributed to the anti-inflammatory effects of dexmedetomidine.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
