Temporal postoperative

The effect of nitrous oxide on homocysteine concentrations and perioperative myocardial ischemia/infarction has been extensively reviewed (5). Nitrous oxide causes acute rises in postoperative homocysteine concentrations temporally associated with postoperative myocardial ischemia. Preoperative oral folate and vitamins Be and Bi2 blunt nitrous oxide-induced postoperative increases in plasma homocysteine (6). 

For assessment of NK-IRA on peritoneal tissue plasminogen activator (tPA) and PAI-1 expression and activity, the temporal expression pattern of tPA and PAI-1 mRNA in peritoneal tissue collected from a 0.5-cm radius of the ischemic buttons are determined by RT-PCR analysis at days 0,1, 3, and 7 after surgery. Based on the results, the effects of NK-IRA administration on tPA and PAI-1 mRNA and protein levels are determined at postoperative day 1 in pedtoneal tissue and fluid by RT-PCR analysis and bioassay, respectively. The rats receive 5.0-mg/kg NK-IRA or vehicle per day. Control samples are collected from 6 nonoperated rats. All samples are immediately frozen in liquid nitrogen and stored at -80°C until used. 

CM administration is indicated to differentiate recurrent tumor from postoperative and postactinic changes at follow-up MRI (Fig. 7.11). A dynamic Tl-weighted postcontrast study with repeated acquisitions enables temporally resolved quantification of CM enhancement. 

Percutaneous nephrostomy can be utilized as a temporizing measure prior to definitive therapy of underlying obstruction. Percutaneous decompression of the obstruction allows time for improvement in renal function, treatment of urinary sepsis, and a more accurate assessment of the renal unit. Children with postoperative ureteral edema, leakage, or obstruction from extrinsic compression of calculi insertion or a percutaneous nephrostomy may be cured.
