- The insertion of nasogastric tubes in comatose, obtunded or anesthetized patients is often difficult, frustrating and time-consuming. A large variety of methods inserting nasogastric tubes in those uncooperative patients have been reported. As a new effective method, we used Savary-Gilliard Wire Guide(R), which is designed for introducing Savary-Gilliard Dilator(R) into a strictured esophagus, for inserting a nasogastric tube in a comatose patient who was intubated with a ballooned tracheostomy tube. The insertion was successful in the first attempt and no complication occurred.

- BACKGROUND
The blood components of priming solution for cardiopulmonary bypass (CPB) may have opposite roles for tissue perfusion, which are the activation of inflammatory reaction and the improvement of oxygen carrying capacity.
This study is aimed to investigate the effect of blood transfusion of priming solution on inflammatory response and tissue perfusion. METHODS: Twenty mongrel dogs randomly allocated and received hypothermic CPB with blood- containing (H group, n=10), or non-hemic (NH group, n=10) priming solution. Gastric intramucosal CO2 concentration (PrCO2), intramucosal pH (pHi), interleukin-8 (IL-8), blood gas and hemodynamic parameters were measured at 1) before CPB, 2) 1 hour during CPB, 3) the end of CPB, 4) 2 hours after CPB, 5) 4 hours after CPB. The ratio of wet to dried lung weight was measured. Statistical verification was performed using repeated measures ANOVA and unpaired t-test.
RESULTS
PrCO2 increased and pHi decreased during the study without significant difference between the groups. IL-8 increased in both groups and IL-8 of H group increased higher than that of NH group during the study. The difference between PaCO2 and end-tidal CO2 of NH group was higher than that of H group at 4 hours after CPB. The ratio of wet to dried lung weight was not significantly different between the groups. CONCLUSIONS: We conclude that the allogenic blood in priming solution aggravates the CPB- induced inflammatory reaction, however, the CPB-induced impairment of gastric mucosal perfusion and the pulmonary edema are not significantly affected, compared to non-hemic solution.
