OBJECTIVETo evaluate the effect of nasogastric decompression tube after gastric cancer operation on the postoperative recovery.
METHODSA total of 174 patients with gastric cancer were prospectively enrolled from December 2009 to March 2011 and randomly divided into non-nasogastric tube control group(n=88) and nasogastric tube group(n=86). Postoperative symptoms, complications, recovery time, and quality of life during hospital stay were compared between the two groups.
RESULTSThe incidences of nausea(14.8% vs. 47.7%, P<0.01), sore throat(6.8% vs. 38.4%, P<0.01), bucking and foreign body sensation(3.4% vs. 20.9%, P<0.01), expectoration obstruction(36.4% vs. 55.8%, P<0.05) were significantly lower in nasogastric tube group than those in the control group. The intervals to ambulation and flatus were(1.46±0.58) d and(3.11±0.77) d in the non-nasogastric tube group, significantly shorter those in nasogastric tube group[(1.68±0.61) d and(3.75±1.03) d]. There was no anastomotic leak or bowel obstruction. The difference in bleeding was not statistically significant[3.4%(3/88) vs. 5.8%(5/86), P>0.05] between the two groups. The quality of life differed between the two groups(mean score, 3.36 vs. 2.78, P<0.01).
CONCLUSIONEarly removal of nasogastric decompression tube is safe and reasonable and can improve the quality of life during hospital stay.

Objective: To observe the prognosis of continuous renal replacement therapy (CRRT) in patients with multiple organ dysfunction syndrome(MODS). Methods: Thirty patients with MODS were enrolled in this study and were divided into two groups (survival group and death group) by their outcomes. All of these patients underwent CRRT for at least 24 h. The levels of interleukin (IL)-1β, IL-4, IL-6, IL-10 and tumor necrosis factor(TNF)-α were measured at the beginning and 3, 6,12 and 24 h after initiation of CRRT. Results: Among these thirty patients, the level of TNF-α came to peak at 12 h, and there was no significant difference between beginning and the end of CRRT. The level of IL-6 in death group was higher than that in survival group. There were correlations among numbers of complications, abnormalities of co-agulation and acute pathologic and chronic health evaluation Ⅱ(APACHEⅡ) separately. Conclusion: Clinical oxygenation and hemodynamics situation can be improved by CRRT, but there were no significant differences in levels of inflammatory mediators between initiation and the end of CRRT.
