[Application of B type natriuretic peptide in fluid therapy after major abdominal operations].

Objective: To evaluate the values of serum level of B type natriuretic peptide level (BNP) in the prediction of fluid overloading after major abdominal operations.

Methods: The levels of BNP were dynamically monitored in 105 patients during peri-operative period from February 2009 to November 2010. Then comparisons were made with age and the volume of positive fluid balance.

Protective effects of Radix Codonopsis on ischemia-reperfusion injury in rats after kidney transplantation.

Purpose: Kidney ischemia-reperfusion injury (IRI) after kidney transplant remains a major problem, separate from immune rejection that can lead to kidney transplant failure and graft function loss. Free radicals, disturbance of microcirculation and the inflammatory cascade appear to be the main contributors. Radix Codonopsis, a traditional Chinese drug used in vascular diseases, is an antioxidant and free radical scavenger.

[Value of microalbuminuria in fluid balance after abdominal surgery].

Objective: To evaluate the relationship among the microalbuminuria, surgical stress and postoperative fluid balance after abdominal surgery.

Methods: A total of 191 patients undergoing an elective abdominal operation were studied. According to the extent of operative trauma, all patients were divided into 4 groups.

[The study of hypertonic saline and hydroxyethyl starch treating severe sepsis].

Objective: To evaluate the effect of 7.5% hypertonic saline (HS) and 6% hydroxyethyl starch (HES) 130/0.4 on early fluid resuscitation for severe sepsis.

[Initial serum lactate level as predictor of morbidity after major abdominal surgery].

Objective: To evaluate the value of immediate postoperative arterial lactate level to predict morbidity after major abdominal surgery.

Methods: 139 patients, 73 males and 66 females, aged (64 +/- 14) (26 - 87), who underwent major abdominal surgery had their levels of arterial lactate, blood routine, blood gas and electrolytes measured after they were sent to the ICU. The physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) and the simplified acute physiology score II (SAPSII) levels in the first 24-hour postoperative period were calculated Multivariate logistic regression analysis was utilized to examine the independent relationship of the initial lactate, blood gas values, and anion gap with the morbidity.

Effects of 7.5% hypertonic saline on fluid balance after radical surgery for gastrointestinal carcinoma.

Aim: To investigate the effects of 7.5% hypertonic saline on positive fluid balance and negative fluid balance, after radical surgery for gastrointestinal carcinoma.

Methods: Fifty-two patients with gastrointestinal carcinoma undergoing radical surgery were studied.
