Purpose. Failed back surgery syndrome is a chronic pain condition requiring rapid, effective, and efficient management. This study evaluates the effect of adding dexmedetomidine to lumbar epidural steroids in patients with failed back surgery syndrome. Methods. Fifty patients suffering from failed back surgery syndrome were randomly assigned to one of two groups, receiving an epidural injection of 20 mL of either a mixture of betamethasone (14 mg) and bupivacaine 0.5 mg (group C) or a mixture of betamethasone (14 mg), bupivacaine 0...

BACKGROUD: The purpose of our study is to evaluate the effect of adding dexmedetomidine to epidural ropivacaine in patients undergoing labor epidural analgesia. METHODS: Eighty healthy women were randomly assigned to two groups: control group(R; n=40) received epidural 0.125% ropivacaine for labor analgesia, whereas the study group (D; n=40) received epidural 0.125% ropivacaine with dexmedetomidine in addition. The blood pressure, heart rate, and the severity of pain of the parturient was assessed, the duration of the first stage and the second stage of labor time, the rate of instrumental delivery and the rate of cesarean section were recorded...

To investigate the effect and safety of dexmedetomidine applied for patient-controlled sedation under combined spinal anesthesia. 150 cases who would be implemented lower limbs operations were randomly divided into patient-controlled sedation group (Group PCS) and control group (Group C) and 75 cases for each group. The ages of patients were between 18 and 65 years old and patients were with American Society of Anesthesiologists (ASA) or level. After being implemented combined spinal anesthesia, patients of Group PCS were undergone patient-controlled sedation by using dexmedetomidine (4μg/mL) with 2mL of load quantity, 1...

BACKGROUND AND AIMS: Alpha (α-2) adrenergic agonists have both analgesic and sedative properties when used as an adjuvant in regional anesthesia. A prospective randomized double-blind study was carried out to evaluate the efficacy of epidural route and to compare the efficacy and clinical profile of dexmedetomidine and clonidine as an adjuvant to bupivacaine with special emphasis on their quality of analgesia, sedation and the ability to provide the smooth intra-operative and postoperative course...

CONTEXT: Postoperative pain management is becoming an integral part of anesthesia care. Various techniques of pediatric pain relief have been designed among which the most commonly practiced is caudal epidural block. Several adjuvants have been used to prolong the duration of caudal analgesia such as clonidine, neostigmine, ketamine, opioids, and ephedrine. We have designed the study using dexmedetomidine as an adjuvant to assess analgesic efficacy, duration of postoperative analgesia, hemodynamic stability, postoperative sedation, and any adverse effects in children...

This report describes a patient case utilizing a nontraditional sedative, continuous infusion ketamine, as an alternative agent for intensive care unit (ICU) sedation. A 27-year-old female presented for neurosurgical management of a coup contrecoup injury, left temporal fracture, epidural hemorrhage (EDH), and temporal contusion leading to sustained mechanical ventilation. The patient experienced profound agitation during mechanical ventilation and developed adverse effects with all traditional sedatives: benzodiazepines, dexmedetomidine, opioids, and propofol...

BACKGROUND: Epidural anesthesia may attenuate the sympathetic hyperactivity and stress response from surgery. In this study, we compared the stress response, hemodynamic variables, and recovery profiles of patients undergoing total IV anesthesia (TIVA) and intraoperative dexmedetomidine with those receiving epidural anesthesia and TIVA. METHODS: Ninety patients undergoing elective open gastrectomy under TIVA were recruited. The dexmedetomidine group (group D, n = 30) received IV dexmedetomidine 0...

CONTEXT: Alpha-2 adrenergic agonists clonidine and dexmedetomidine, are well known to produce analgesia through an opioid independent mechanism. Alpha-2 agonists are used as an adjuvant to local anesthetic agents to extend the duration of spinal, epidural and brachial plexus blocks. AIMS: We compared clonidine and dexmedetomidine as an adjuvant to Ropivacaine in cervical epidural anesthesia (CEA) with respect to onset and duration of sensory block, duration of analgesia and adverse effects...

BACKGROUND AND AIM: To assess the amount of propofol required for induction based on bispectral index (BIS) after administering epidural anesthesia with ropivacaine alone and ropivacaine with dexmedetomidine in patients undergoing lower extremities and abdominal surgeries. SUBJECTS AND METHODS: A double-blinded randomized clinical trial was carried out in 60 patients over a period of 2 years in a tertiary care hospital. American Society of Anaesthesiologists I or II in age group 18-65 years were included in the study...

INTRODUCTION: Pre-emptive caudal epidural is a proven technique for providing analgesia for spinal surgeries. Prolonged pain relief with no motor blockade is desired for early mobilisation. AIM: Present study aimed to evaluate the effect of addition of Inj dexmedetomidine to caudal ropivacaine on the duration of analgesia, haemodynamic profile and the associated side effects. MATERIALS AND METHODS: In this prospective double-blind study a total of 60 patients undergoing lumbosacral spine surgery were randomised to receive 20 cc of pre-emptive caudal epidural injection of either inj ropivacaine 0...

INTRODUCTION: Levobupivacaine is the s-isomer of racemic Bupivacaine. It is less cardio, neurotoxic and equally potent local anaesthetic compared to its racemate. It is known to cause less Depression of myocardial contractility. Dexmeditomidine when used via epidural route has synergistic effect with local anaesthetics. Majority of patients presenting for vascular surgery are elderly and have associated co-morbidities like diabetes, hypertension, and coronary artery disease. We intend to study safety and efficacy of epidural Levoupivacaine and Dexmedetomidine in this group of patients...

BACKGROUND: There is experimental evidence that dexmedetomidine has neuroprotective effects. So, it could be expected that its intrathecal or epidural administration presents no harm. However, whether dexmedetomidine is neurotoxic to the spinal cord remains to be fully elucidated. OBJECTIVE: To evaluate the effect of preservative-free dexmedetomidine administered as a subarachnoid single injection on the spinal cord and meninges of rabbits. STUDY DESIGN: Research article...

Nonintubated video-assisted thoracoscopic surgery (VATS) has been reported to be safe and feasible for patients with various thoracic diseases, including those who have respiratory dysfunction. In nonintubated VATS, it is important to maintain spontaneous respiration and to obtain a satisfactory operating field through adequate collapse of the lung by surgical pneumothorax. Therefore, we need to minimize the patient's physical and psychological discomfort by using regional anesthesia and sedation. If analgesia and sedation are inadequate, conversion to intubated general anesthesia may be required...

This study hypothesized that different types of anaesthesia management would result in similar postoperative sleep quality. In this prospective single-blind investigation, 219 patients undergoing elective thoracic surgery were randomized into three arms: general anaesthesia, as the control group (group C); general anaesthesia combined with thoracic epidural anaesthesia (TEA) (group E); and general anaesthesia combined with infusion of 1 μg/kg dexmedetomidine (group D). Plasma samples were obtained to measure the amine and inflammatory cytokine concentrations...

BACKGROUND: The quality and duration of analgesia is improved when a local anesthetic is combined with alpha 2 adrenergic agonist. Though, the effects of clonidine on local anesthetics have been extensively studied, there are limited studies demonstrating the effects of epidural dexmedetomidine on local anesthetics. The aim of our study is to compare the effect of clonidine and dexmedetomidine when used as an adjuvant to epidural ropivacaine in lower abdominal and lower limb surgeries...
