[The role of serum osmolality monitoring in patients with severe intracranial lesion].
We dynamically determined serum osmolality in 1379 patients with severe intracranial lesion for 2843 times between January 1992 and July 1995. Using auto-control and after abandoned osmolality related interference factors we obtained the following results. Quantitative correlation analysis on the level of serum osmolality, intracranial pressure and the dose of mannitol showed that there was a negative correlation between the level of serum osmolality and intracranial pressure, while a positive correlation existed between the intracranial pressure and the dose of mannitol. ⋯ The efficious duration of mannitol, two different ways of diminishing or withdrawing the dose of mannitol, and the more safer velocity for correcting the state of hyperosmolality were also discussed. We conclude that to monitor the dynamic change of serum osmolality from time to time is of great help in lowering the incidence and mortality of hyperosmotic complications. Serum osmolality monitoring plays an important role in making fluid balance and compromizing the contradiction between dehydration and infusion as well as prevention and therapy of hyperosmotic complications, and outcome estimation as well.

[Reconstruction of right ventricular outflow tract using transannular patch in 52 children with tetralogy of Fallot].
52 children with tetralogy of Fallot received reconstruction of right ventricular outflow tract (RVOT) by using transannular patch. The indications for using transannular patch to reconstruct RVOT, patch materials, and the standard of enlargement pulmonary annulus were studied. ⋯ The autologous pericardium was the most acceptable material for patch. All patients showed no obstruction of RVOT during early and late postoperative follow-up, althought most of them had certain degree of pulmonary regurgitation (PR) in first postoperative year, whicli was gradually attenuated as their life time long-drawn, with better exertion tolerance.
