    Entropy score, patent ductus arteriosus (PDA), and cardiopulmonary bypass (CPB): ligation of PDA on CPB can compromise cerebral blood flow.
    (Annals of cardiac anaesthesia, 2011)
    A patent ductus arteriosus (PDA) is often present in patients undergoing correction of congenital heart disease. It is well appreciated that during cardiopulmonary bypass (CPB), a PDA steals arterial inflow into pulmonary circulation, and may lead to systemic hypoperfusion, excessive pulmonary blood flow (PBF) and distention of the left heart. Therefore, PDA is preferably ligated before initiation of CPB. We describe acute decreases of arterial blood pressure and entropy score with the initiation of CPB and immediate increase in entropy score following the PDA ligation in a child undergoing intracardiac repair of ventricular septal defect and right ventricular infundibular stenosis. The observation strongly indicates that a PDA steals arterial inflow into pulmonary circulation and if the PDA is dissected and ligated on CPB or its ligation on CPB is delayed the cerebral perfusion is potentially compromised.

    Postoperative sialadenitis following retromastoid suboccipital craniectomy for posterior fossa tumor
    (JOURNAL OF ANESTHESIA, 2009)
    During retromastoid and far-lateral posterior fossa surgical approaches the head may be positioned at the extreme limits of rotation and extension. In rare instances, patients may develop acute sialadenitis after surgery as a consequence of such positioning. In those patients, the neck/facial swelling is contralateral to the craniectomy site. The mechanism implicated in acute sialadenitis in the patient described in this report was because of obstruction to the salivary duct due to surgical positioning. The course of this complication is typically benign if it is identified early in the postoperative period.
