Randomized Controlled Trial Comparative StudyDoes the addition of magnesium to bupivacaine improve postoperative analgesia of ultrasound-guided thoracic paravertebral block in patients undergoing thoracic surgery?
Magnesium is a plentiful intracellular cation that has been reported to possess analgesic effect. The present study was aimed to see whether addition of magnesium to bupivacaine in thoracic paravertebral block (TPVB) improved the analgesic effect after thoracic surgery. ⋯ Addition of magnesium to bupivacaine in TPVB improved the analgesic effect of bupivacaine in patients undergoing thoracic surgery.

Meta Analysis Comparative StudyLower incidence of emergence agitation in children after propofol anesthesia compared with sevoflurane: a meta-analysis of randomized controlled trials.
Emergence agitation (EA) from general anesthesia has been reported as an adverse effect of sevoflurane in children. We describe a meta-analysis of randomized controlled trials that compared the incidence of EA between children who underwent sevoflurane anesthesia and those who underwent propofol anesthesia. ⋯ Our meta-analysis demonstrated that EA in children is less likely to occur after propofol anesthesia compared with sevoflurane anesthesia.

Randomized Controlled Trial Comparative StudyEffective analgesia with ultrasound-guided interscalene brachial plexus block for postoperative pain control after arthroscopic rotator cuff repair.
Ultrasound (US)-guided continuous interscalene brachial plexus block (CBPB) is known to provide effective pain relief for arthroscopic rotator cuff repair. This study was conducted to compare analgesic efficacy and forearm muscle tone of the basal infusion rate and bolus dose of 0.2 % ropivacaine for US-guided CBPB with intravenous patient-controlled analgesia (IV-PCA). ⋯ The bolus dose of 0.2 % ropivacaine using US-guided CBPB would provide equivalent analgesic efficacy comparable with the basal infusion and motor weakness comparable with IV-PCA after arthroscopic rotator cuff repair.

Randomized Controlled TrialEffect of clonidine added to lidocaine for sub-Tenon's (episcleral) anesthesia in cataract surgery.
We aimed to evaluate the duration of anesthesia, analgesia and ocular akinesia of clonidine added to lidocaine in sub-Tenon's anesthesia in patients undergoing cataract surgery. ⋯ The addition of clonidine 1 μg/kg to 2 % lidocaine in sub-Tenon's anesthesia for cataract surgery increased the duration of sensory anesthesia, ocular akinesia, and the duration of analgesia.

Review Case ReportsDexmedetomidine-induced atrioventricular block followed by cardiac arrest during atrial pacing: a case report and review of the literature.
Sinus bradycardia is a well-known consequence of stimulation of presynaptic α2 adrenergic receptors due the adminstration of dexmedetomidine. One of the most serious adverse effects of dexmedetomidine is cardiac arrest. Some cases demonstrating such an arrest due to the indiscriminate use of this drug were recently reported. ⋯ The PQ interval in electrocardiography gradually prolonged during the infusion; finally, complete atrioventricular block and subsequent cardiac arrest occurred. Immediate cardiopulmonary resuscitation was carried out, including re-intubation, and recovery of spontaneous circulation was attained 15 min after the event. The patient was discharged from hospital on the 25th postoperative day without any neurological complications.
