To compare the sedative, hemodynamic, and respiratory effects of dexmedetomidine and propofol in children undergoing magnetic resonance imaging procedures. ⋯ We conclude that although propofol provided faster anesthetic induction and recovery times, it caused hypotension and desaturation. Dexmedetomidine could be an alternative, reliable sedative drug to propofol in selected patients.

Noonan syndrome is a genetically transmitted autosomal dominant disorder characterized by various anatomic anomalies and pathophysiologic derangements. Anesthetic management in such cases poses a multitude of challenges, especially related to the airway management and maintenance of cardiovascular stability. ⋯ The child was operated on for release of bilateral neck bands under general anesthesia. The case report pertains to the successful airway and anesthetic management in the background of difficult airway and existence of various cardiac lesions.

Tetrology of Fallot (TOF) is the most commonly encountered congenital cardiac lesion in pregnancy. Although there are controversies regarding safe anesthetic technique for parturient with TOF, we use low-dose sequential combined-spinal epidural anesthesia in such a case posted for Cesarean section and found that low dose (0.5 ml of 0.5%) intrathecal bupivacaine and fentanyl with sequential epidural bupivacaine supplementation was adequate for the performance of an uncomplicated Cesarean section with minimal side effects and good fetal outcome. Thus, though the choice of anesthesia can vary in such patients, low-dose sequential combined-spinal epidural can be a safe alternate to achieve good anesthesia with impressive cardiovascular stability.

Ropivacaine is a long-acting amide local anesthetic, which is structurally very similar to bupivacaine but produces less motor block and less cardiac and central nervous system toxicity. It is also about 40% less potent than bupivacaine. Our double blind study was designed to compare the clinical efficacy of the equipotent doses of ropivacaine 0.75% and bupivacaine 0.5% for epidural anesthesia and ropivacaine 0.2% and bupivacaine 0.125% for post-operative analgesia in patients undergoing bilateral mesh hernioplasty. ⋯ The equipotent doses of ropivacaine and bupivacaine provided good quality epidural anesthesia and post-operative analgesia.

AIMS AND CONTEXT: To evaluate the efficacy of adding clonidine to bupivacaine in bilateral infraorbital nerve block for hemodynamic changes, requirement of opioids, volatile agent, and muscle relaxants intraoperatively and relief of pain postoperatively ⋯ Addition of clonidine as an adjunct to local anesthetic significantly decreased the requirement of other anesthetic drugs and significantly prolonged the duration of postoperative analgesia without any adverse effects.
