BACKGROUND: Traumatic brain injury causes a disruption of the vascular endothelial glycocalyx layer that is associated with an overactivation of the sympathoadrenal system. We hypothesized that early and unselective beta-blockade with propranolol alone or in combination with the alfa2-agonist clonidine would decrease brain edema, blood-brain-barrier permeability and glycocalyx disruption at 24 hours after trauma. METHODS: We subjected fifty-three adult male Sprague-Dawley rats to lateral fluid-percussion brain injury and randomized infusion with propranolol (n=16), propranolol+clonidine (n=16), vehicle (n=16) or sham (n=5) for 24 hours...

BACKGROUND: Epidural labor analgesia has not been fully accepted despite many advantages. Many times, the pregnant females reach hospital without antenatal checkup, and at that time, "episiotomy infiltration" becomes an ideal method for vaginal delivery. One of the most important problems after episiotomy is the severe perineal pain on the 1(st) day of postpartum period. OBJECTIVES: We compared the efficacy of clonidine 1 μg/kg as an adjuvant to 20 mg/ml lignocaine infiltration along the line of episiotomy incision for prolonging the duration and quality of analgesia with respect to various activities by single injection...

BACKGROUND: Many studies are there using adjuvants such as clonidine and fentanyl with bupivacaine in the subarachnoid block for prolonging postoperative analgesia. However, literature is divided regarding the dosage and efficacy of both intrathecal adjuvants. Furthermore, these adjuvants have their own side effects. Hence, search for ideal intrathecal adjuvant between clonidine and fentanyl to bupivacaine goes on. AIM: The aim of the present study was to compare the effect of intrathecal clonidine and fentanyl as adjuvant to bupivacaine in the subarachnoid block for lower limb orthopedic surgery...

BACKGROUND: Sleep disturbances, in particular insomnia, represent a common problem in children with neurodevelopmental disabilities (NDDs). Currently, there are no approved medications for insomnia in children by the US Food and Drug Administration or European Medicines Agency and therefore they are prescribed off-label. We critically reviewed pediatric literature on drugs as well as nonpharmacological (behavioral) interventions used for sleep disturbances in children with NDDs. METHODS: PubMed, Ovid (including PsycINFO, Ovid MEDLINE(®) , and Embase), and Web of Knowledge databases were searched through February 12, 2017, with no language restrictions...

The central amygdala is critical for the acquisition and expression of fear memories. This region receives a dense innervation from brainstem noradrenergic cell groups and has a high level of α2-adrenoceptor expression. Using whole-cell electrophysiological recordings from rat brain slices, we characterise the role of pre-synaptic α2-adrenoceptor in modulating discrete inhibitory and excitatory connections within both the lateral and medial division of the central amygdala. The selective α2-adrenoceptor agonist clonidine blocked the excitatory input from the pontine parabrachial neurons onto neurons of the lateral central amygdala...

Substance use disorders are common among incarcerated individuals, and prescribed medications have been reported as abused, diverted, or otherwise misused in correctional settings. We conducted a retrospective chart review of electronic medical records and reports on institutional charges for misuse of authorized medication by inmates in the New Jersey Department of Corrections between 2003 and 2013. The most frequently cited medications for misuse were gabapentin, diphenhydramine, clonidine, and ibuprofen...

The effect of clonidine administered intrathecally (i.t.) on the mortality and the blood glucose level induced by sepsis was examined in mice. To produce sepsis, the mixture of D-galactosamine (GaLN; 0.6 g/10 ml)/lipopolysaccharide (LPS; 27 µg/27 µl) was treated intraperitoneally (i.p.). The i.t. pretreatment with clonidine (5 µg/5 µl) increased the blood glucose level and attenuated mortality induced by sepsis in a dose-dependent manner. The i.t. post-treatment with clonidine up to 3 h caused an elevation of the blood glucose level and protected sepsis-induced mortality, whereas clonidine post-treated at 6, 9, or 12 h did not affect...

BACKGROUND: Clonidine used as an adjuvant to ropivacaine have been shown to prolong the duration of peripheral nerve blocks. The mechanism of action remains unclear. We hypothesized, that clonidine used as an adjuvant to ropivacaine extends the duration of an adductor canal block (ACB) by a peripheral mechanism, compared to ropivacaine alone when controlling for systemic effects. METHODS: We conducted a paired, blinded, randomized trial in healthy volunteers. Participants received bilateral ACBs containing 20 ml ropivacaine 0...

Although beneficial in acute and chronic pain management, the use of local anaesthetics is limited by its duration of action and the dose dependent adverse effects on the cardiac and central nervous system. Adjuvants or additives are often used with local anaesthetics for its synergistic effect by prolonging the duration of sensory-motor block and limiting the cumulative dose requirement of local anaesthetics. The armamentarium of local anesthetic adjuvants have evolved over time from classical opioids to a wide array of drugs spanning several groups and varying mechanisms of action...

OBJECTIVE: We conducted an extensive review of the literature and tried to cite the most recent recommendations concerning the pheochromocytoma (PHEO). METHODS: Pub Med and Google Scholar databases were searched systematically for studies concerning pheochromocytomas (intra-adrenal paragangliomas) from 1980 until 2016. Bibliographies were searched to find additional articles. RESULTS: More than four times elevation of plasma fractionated metanephrines or elevated 24-h urinary fractionated metanephrines are keys to diagnosing pheochromocytoma...

OBJECTIVE: Acute dystonia in children is distressing, painful and can progress to life-threatening status dystonicus. Typical management involves benzodiazepines which can result in respiratory depression requiring PICU admission. Clonidine is less respiratory-depressant, and by facilitating sleep, switches dystonia off. It can also be administered via enteral, continuous intravenous infusion, and transdermal slow release routes. We describe the dose range and safety profile of clonidine management in a case-series of children with severe acute exacerbation of dystonia in a tertiary hospital setting...

Agitation is one of the most common issues that critically ill patients experience. Medications used to manage agitation are often administered intravenously or intramuscularly in the acutely agitated, critically ill patient. However, a multimodal approach that utilizes multiple routes of administration may be appropriate. This review summarizes the available literature on oral antipsychotics, clonidine, and valproic acid to manage agitation in critically ill patients while also focusing on their pharmacology and appropriate monitoring...
