Pediatric laryngospasm is an anesthetic emergency. It is a relatively common phenomenon that occurs with varying frequency dependent on multiple factors. In view of this and the clear risks to the patient when it occurs, a consensus committee has been established to determine the evidence based management of this condition. This article will cover the definition, causes and recognition of laryngospasm and the evidence behind a proposed algorithm for its' management.

This report describes a prospective randomized trial of 503 patients who underwent a cardiac catheterization or interventional procedure at a single institution. In an effort to study femoral complications postprocedure, we evaluated three methods of femoral artery hemostasis as well as 38 variables that were felt to potentially relate to local complications. Only a marginally significant relationship between the hemostasis method and complication rate was found. The factors that contributed to femoral artery complications were: restarting heparin postsheath removal, number of procedures done during one hospitalization, noncompliance of the patient with bedrest after the procedure, number of arterial punctures to initiate the procedure, and preprocedure treatment with corticosteroids.

P Pu ur rp po os se e: : Propofol, by virtue of its favourable pharmacokinetic profile, is suitable for maintenance of anesthesia by continuous infusion during neurosurgical procedures in adults. It is gaining popularity for use in pediatric patients. To determine the effects of propofol on cerebral blood flow in children, middle cerebral artery blood flow velocity (Vmca) was measured at different levels of propofol administration by transcranial Doppler (TCD) sonography.M Me et th ho od ds s: : Twelve ASA I or II children, aged one to six years undergoing elective urological surgery were randomized to receive one of two propofol dosing regimens. Half of the patients received propofol in an escalating fashion, initially targeting an estimated steady-state serum concentration of 3 µg·mL -1 , which was then doubled. The other half received propofol designed initially to target the high concentration followed by the lower one. In each child anesthesia was induced and maintained with propofol according to the protocol, rocuronium was given to facilitate tracheal intubation, and a caudal epidural block was performed. A TCD probe was placed appropriately to measure Vmca. Cerebral blood flow velocity (CBFV), mean arterial pressure (MAP) and heart rate (HR) were recorded simultaneously at both levels of propofol administration.R Re es su ul lt ts s: : Twelve patients were studied. At the higher estimated target serum propofol concentration there were significant decreases in Vmca (17%, P < 0.001), MAP (6%, P < 0.002) and HR (8%, P < 0.05) when compared to the lower targeted concentration.C Co on nc cl lu us si io on n: : This study shows that a higher rate of propofol infusion is associated with lower CBFV and MAP values in children. Propofol's cerebral vasoconstrictive properties may be responsible for this finding.
