Comparison of analytical methods in the determination of two venlafaxine fatalities.

Two venlafaxine (Effexor)-related deaths are reported with comparison of results from the analysis of specimens using capillary gas chromatography with a nitrogen-phosphorous detector (GC-NPD) and high-performance liquid chromatography (HPLC) using a UV-vis detector. Blood concentrations in Case 1 were 7.27 micrograms/mL venlafaxine and 5.03 micrograms/mL O-desmethylvenlafaxine, and Case 2 had 89.67 micrograms/mL venlafaxine with 3.44 micrograms/mL of the desmethyl metabolite. A comparison of analytical methods and specimen concentration is presented.

Tracheobronchial compression in acyanotic congenital heart disease.

Children with acyanotic congenital heart disease frequently develop respiratory difficulties such as atelectasis, pneumonia, or infantile lobar emphysema. In some cases, the cause of the respiratory difficulty is compression of the tracheobronchial tree by hypertensive dilated pulmonary arteries, since this type of heart disease frequently demonstrates large left-to-right intracardiac shunts. Sites of predilection for compression include the left main bronchus, the left upper lobe bronchus, the junction of the right bronchus intermedius and right middle lobe bronchus, and the left side of the distal trachea. Cardiac anomalies which predispose to this type of compression include ventricular septal defect, patent ductus arteriosus, interruption of the aortic arch, and tetralogy of Fallot. Pulmonary arteriopexy may relieve the tracheobronchial compression.

Pharmacologic treatment of catheter-related thrombus in pediatrics.

Venous and arterial catheters are being used with increasing frequency in pediatric populations. As part of the comprehensive management of these catheters, nurses need to be aware of the more common catheter-related thrombus problems. An understanding of pharmacologic treatment using Streptokinase and Urokinase for thrombus in central lines, hemodialysis grafts, and umbilical artery catheters can help nurses develop protocols to care for patients with these devices. The appropriate use of thrombolytic therapy can restore function to many catheters thereby saving the patient the cost and morbidity associated with removal and replacement of a dysfunctional catheter.
