The axillary vein was evaluated as an alternative access site for central venous catheterization in critically ill infants and children. Children were placed in the Trendelenberg position (when possible) with arm abducted 100 to 130°. The vein was entered parallel and inferior to the artery. Success rate for catheterization was 79% (41/52). Catheter diameter range was 3 to 8.5 F and catheter length range was 5 to 30.5 cm. Median patient weight was 7.0 kg (3.0 to 59 kg). Median age was 0.91 years (14 days to 9 years). All central lines ended in the subclavian, innominate, or superior vena cava. Median catheter duration was 8 days (2 to 22 days). A total of 338 patient catheter-days were studied. Central venous pressure was successfully monitored in five of five attempts. Complications with insertion (3.8% of attempts) included one pneumothorax and one hematoma. Complications during catheter duration (9.8% of catheters, 1.1% per catheter-day) included one instance each of venous stasis, venous thrombosis, catheter sepsis, and parenteral nutrition infiltration. No complication contributed to a patient mortality. Success and complication rates were comparable with those in jugular catheterization studies in children. The axillary approach is an acceptable route for central venous catheterization in critically ill infants and children.
During an 18-month period in a pediatric intensive care unit, nine patients with vocal cord paralysis were identified using flexible bronchoscopy. When tracheally extubated, each child was found to have stridor. The children ranged in age from 17 days to 5½ years. Two patients had unilateral paralysis, but neither required tracheostomy. Seven patients displayed bilateral abductor vocal cord paralysis. Of these, six patients required tracheostomy. Surgical injury to the recurrent laryngeal nerve was the probable cause in two patients. The other seven patients had neurologic disorders with documented or suspected increases of intracranial pressure. Four of the seven patients with bilateral abductor vocal cord paralysis regained cord mobility within 4 months. Both children with unilateral cord paralysis have no stridor and vocalize well 1 year later. Cord paralysis in the setting of intracranial hypertension probably results from compression or ischemia of the vagus nerve before it exits the skull. Early visualization of the larynx should be done in patients who become stridulous when extubated, especially those with prior thoracic procedures or with neurologic disorders associated with intracranial hypertension.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
