Dexmedetomidine leads to the amelioration of stress response to surgery.
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.

It is a peer reviewed medical journal published regularly since 1984. It was previously known as quarterly "SPECIALIST" till December 31st 1999. It publishes original research articles, review articles, current practices, short communications & case reports. It attracts manuscripts not only from within Pakistan but also from over fifty countries from abroad.
Copies of PJMS are sent to all the import medical libraries all over Pakistan and overseas particularly in South East Asia and Asia Pacific besides WHO EMRO Region countries. Eminent members of the medical profession at home and abroad regularly contribute their write-ups, manuscripts in our publications. We pursue an independent editorial policy, which allows an opportunity to the healthcare professionals to express their views without any fear or favour.
