Pediatric emergencies.

The unique anatomic and physiologic characteristics of neonatal and pediatric patients make diagnosis, monitoring, and treatment a challenge. Adult parameters cannot be relied on in these patients, and an awareness of these unique characteristics is essential for any practitioner with a neonatal and pediatric patient base. In addition, many laboratory and pharmacologic data differ dramatically in neonates compared with adults of the same species. Familiarity with these variations is essential in the monitoring and treatment of the neonatal and pediatric illness, such as hypovolemia, shock, and sepsis.

Surgical correction of subaortic stenosis via right ventriculotomy and septal resection in a dog.

After 2 years of medical management with a beta-adrenoreceptor blocking agent, a 30-month-old castrated male Golden Retriever with subaortic stenosis was treated surgically because of progression of its condition. In an attempt to achieve complete relief of the left ventricular outflow obstruction, a modified Konno procedure consisting of right ventriculotomy and septal myectomy from the infundibular portion of the right ventricle was performed; this combination of procedures allowed wide resection of the septal portion of the left ventricular outflow obstruction. Two years after surgery, the mass of the dog's left ventricle had decreased and the peak calculated pressure gradient across the aortic valve had decreased to 40 mm Hg, compared with a preoperative value of 240 mm Hg; at that evaluation, the dog had gained weight and was able to play normally. It is suggested that use of this modified approach to the outflow tract may have a positive effect on long-term survival time in dogs with subaortic stenosis.
