BACKGROUND: Dexmedetomidine, a selective alpha-2 agonist, has sedative, analgesic, and anxiolytic effects without respiratory depression. Dexmedetomidine can cause a biphasic cardiovascular response, and induce transient hypertension. Hypotension is a common complication of spinal anesthesia. Decreasing anxiety of patients before procedure is important for high quality of procedure. This study aimed to compare the incidence of hypotension and patients' anxiety and comfort levels when dexmedetomidine was intravenously administered before and after spinal anesthesia...

S Bala Bhaskar, D Srinivasalu
Chronic demyelinating disorders have multifactorial origin but common important physiologic and anaesthetic considerations. Choice of anaesthesia technique and the drugs used, undertanding the pros and cons of using central neuraxial blocks will help in successful management of such patients. We describe the anaesthetic management of a 34-year-old male with chronic inflammatory demyelinating polyneuropathy posted for cystolithotripsy.

BACKGROUND: Intrathecal ketamine has been studied extensively in animals, but rarely in humans. Intrathecal dexmedetomidine prolongs the duration of spinal anesthesia. OBJECTIVE: To investigate the efficacy and safety of intrathecal dexmedetomidine, ketamine, or both when added to bupivacaine for postoperative analgesia in major abdominal cancer surgery. DESIGN: Double-blinded, randomized, controlled trial. SETTING: Academic medical center...

To compare the effects of intrathecal dexmedetomidine and intrathecal morphine as supplements to bupivacaine in cesarean sections under spinal anesthesia. Full-term parturients (n=120) undergoing elective cesarean sections under spinal anesthesia were randomly allocated into three groups: Group B received 10 mg bupivacaine, Group BD received 10 mg bupivacaine plus 5 µg dexmedetomidine, and Group BM received 10 mg bupivacaine plus 100 µg morphine. The onset and regression time of sensory and motor blockade, postoperative analgesia, and side effects were recorded...

BACKGROUND AND AIMS: Inrathecal opioids like morphine added to local anaesthetic agents have been found to be effective in achieving prolonged post-operative analgesia. Intrathecal dexmedetomidine may be devoid of undesirable side effects related to morphine and hence, this study was designed to evaluate analgesic efficacy, haemodynamic stability and adverse effects of both these adjuvants in patients undergoing gynaecological surgeries. METHODS: This was a prospective, randomised, double blind study involving 25 patients in each group...

BACKGROUND AND AIMS: Trials are being carried out to identify an adjuvant to intrathecal bupivacaine that preferably potentiates postoperative analgesia. This prospective, randomized, double-blind study was aimed to compare the onset and duration of sensory and motor block, postoperative analgesia and adverse effects of dexmedetomidine or midazolam given with 0.5% hyperbaric bupivacaine for spinal anesthesia. MATERIAL AND METHODS: A total of 80 patients, scheduled for vaginal hysterectomies, were randomly allocated to Group D (n = 40) to receive intrathecally 3...

BACKGROUND AND INTRODUCTION: Spinal block, a known technique to obtain anaesthesia for infraumblical surgeries. Now physician have advantage of using adjuvant to prolong the effect of intrathecal block, which can be given either intravenously or intrathecally, dexmedetomidine is one of them. We studied effect of intravenous dexmedetomidine for prolongation of duration of intrathecal block of 0.5% bupivacaine block.

BACKGROUND: Dexmedetomidine, a selective alpha2 adrenoceptor agonist, has been used as adjuvant to spinal anaesthesia. AIM: To find out the optimum dose of dexmedetomidine to be used in lower abdomen surgery intrathecally. MATERIALS AND METHODS: This was a randomized, controlled, double blinded study which included adult ASA I and II patients. They were allocated into five groups (n=20).

INTRODUCTION: Various adjuvants like morphine, buprenorphine and fentanyl, clonidine, ketamine are being used in anaesthetic practice since long for improvement of peri-operative analgesia following spinal anaesthesia. Such adjuvants have been helpful in induction of early ambulation but at the cost of their associated adverse effects. Therefore search for an effective adjuvant is still going on. Currently Dexmedetomidine, a highly selective α2-adrenoreceptor agonist is being studied for its adjuvant action in spinal anaesthesia...

BACKGROUND: Addicted patients have innate tolerance to local anesthetics in both neuraxial and peripheral blocks. Dexmedetomidine (Dex) is a highly selective α2 adrenergic receptor agonist used as additive to increase quality and duration of peripheral nerve blocks. OBJECTIVES: The current study aimed to compare the effect of dexmedetomidine and fentanyl additives on bupivacaine to prolong the duration of block and minimizing side effects. PATIENTS AND METHODS: Patients were candidates for elective surgery less than three hours of lower abdomen or lower extremities surgeries...

BACKGROUND: The extended analgesic efficacy of intrathecal dexmedetomidine (ITD) has been investigated in a few clinical trials; however, there is a lack of conclusive evidence upon its ideal dosage. OBJECTIVES: To elucidate the dose-response relationship between ITD and subarachnoid block characteristics, particularly the duration of analgesia and differential analgesia (DA: defined as time difference from the offset of motor blockade to the first analgesic requirement on numerical rating scale = 4...

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.

BACKGROUND: General anesthesia as a technique for laparoscopic cholecystectomies has disadvantage in terms of the stress response, lack of postoperative analgesia and emesis. Regional anesthesia offers advantages over general anesthesia in terms of cost, postoperative analgesia, intact respiratory control mechanism and early ambulation. Shoulder tip pain remains the main concerns that can be alleviated by adding various adjuvants to local anesthetics. AIMS AND OBJECTIVES: To study the effect of adding intrathecal dexmedetomidine to bupivacaine to decrease shoulder tip pain, onset and duration of sensory and motor block, hemodynamic changes and side effects if any...

BACKGROUND AND AIMS: Dexmedetomidine (DMT), as intrathecal adjuvant has been shown to successfully prolong duration of analgesia but delay the motor recovery. Hence, this study was designed to find out the dose of DMT which can provide satisfactory analgesia without prolonging motor block. METHODS: A total of 50 patients scheduled for elective perianal surgeries were randomly allocated to Groups C or D (n = 25). Group D received hyperbaric bupivacaine 0.5% 4 mg + DMT 5 μg and Group C received hyperbaric bupivacaine 0...
