A prospective randomized comparative study to evaluate efficacy of intrathecal dexamethasone and dexmedetomidine added as adjuvant to bupivacaine in pregnant patients posted for elective LSCS

Any individual undergoing surgery is concerned about postoperative discomfort. It modifies the body’s physiological reaction and impacts an individual’s psychological state. A physician can meet early mobilization goals by effectively managing postoperative pain and preventing related co-morbidities. Targeting different phases of the pain pathway, from perception to central modulation, is successfully accomplished through the use of different drug combinations and regional anesthetic block techniques. Local anaesthetics injected intrathecally in a single injection create a superb surgical field and can even make a patient pain-free two to three hours following surgery. By adding certain adjuncts, this period can be prolonged, and there will be long-term benefits in terms of decreasing the dosage of opioid analgesics. Because of its faster start of the action and low side effects, spinal anaesthesia is the procedure most frequently used for caesarean sections. Many intrathecal additives have been explored since it has a limited role in postoperative pain control. Adjuvants such as opioids, clonidine, adrenaline, and phenylephrine have been explored recently. These chemicals have been linked to several problems, including tachycardia, respiratory depression with opioids, hypertension with adrenaline and clonidine, and excessive sedation. In this study, our primary objective is to compare the duration of postoperative analgesia between Dexamethasone and dexmedetomidine, as Dexamethasone is an anti-inflammatory drug and dexmedetomidine is an alpha-two agonist that binds with a G protein-coupled receptor. our secondary objectives include comparing intraoperative hemodynamics, intraoperative sedation, and intraoperative shivering between Dexamethasone and dexmedetomidine.
