Comparative Study
A comparison of placement techniques and complications of externalized catheters and implantable port use in children with cancer.
The complications associated with the placement and use of Hickman catheters (n = 120), Broviac catheters (n = 146), and implantable ports (n = 93) in children with cancer were analyzed. Percutaneously placed central venous access devices (CVADs) tended to fail less often (P = .86) and to develop infections less often (P = .056) than surgically placed CVADs. The difference in complications with percutaneous versus surgically placed CVADs requires confirmation in a randomized trial to assure they are not a result of differences in patient characteristics. ⋯ Ports also remained infection-free longer than externalized catheters (P = .0014). The greatest risk of infection occurs in the first 100 days of use, particularly for ports. This study demonstrates that for long-term use (greater than 100 days) ports are superior to externalized catheters in children with cancer.

Extracorporeal membrane oxygenation (ECMO) has been successful treatment (80% survival) in over 2,000 neonates with severe respiratory failure (80% predicted mortality without ECMO). Neonates on ECMO require frequent blood product replacement, which increases donor exposure (DE) and the risk of transfusion related complications. Successful, widespread usage of ECMO in neonatal respiratory failure is placing increased numbers of surviving infants at risk for acute and long-term transfusion related problems. ⋯ In a protocol (n = 9) to minimize DE risks, exchange transfusions were eliminated and PRBC transfusion volumes were increased to 15 mL/kg. Empiric use of FFP and CRYO was discontinued. The blood bank divided standard units of PRBCs into four aliquots and dispensed each aliquot sequentially before dispensing blood from another unit.(ABSTRACT TRUNCATED AT 250 WORDS)

The presence of a parent in the operating room (OR) during induction of anesthesia is controversial. In order to assess the feasibility, safety, and acceptance of this practice, we evaluated a near-4-year experience with 3,086 patients less than 15 years of age, who were operated on at a free-standing ambulatory surgical center. The age distribution was: 1 to 23 months, 790; 2 to 5 years, 1,190; 6 to 10 years, 775; and 10 to 15 years, 331. ⋯ The feedback during follow-up from those parents has been excellent. Nurses, anesthesiologists, and surgeons are enthusiastic about the program. In the examined setting, this approach has proven safe, simple, and effective.

Between 1964 and 1987, 12 patients with mesoblastic nephroma were treated. The BP was measured preoperatively in five patients, four of whom were hypertensive. Following nephrectomy, the BP returned to normal. ⋯ Staining was positive in ten patients. The most intense staining was noted in the areas of cortex entrapped within the tumour, and in perivascular spaces not associated with entrapped cortex. These findings suggest that hypertension secondary to increased tumour associated renin production is a feature of congenital mesoblastic nephroma.
