RESUMEN
Objective To investigate the effect of stroke volume variability (SVV)-guided intraoperative fluid restriction on liver and renal function in patients undergoing hepatic lobectomy. Methods Forty ASA Ⅰ - Ⅲpatients of both sexes aged 33-60 yr weighing 52-80 kg undergoing elective hepatic lobectomy were randomly divided into 2 groups ( n = 20 each): group A routine fluid administration and group B restricted fluid administration.Anesthesia was induced with iv lidocaine, fentanyl and TCI of propofol (target plasma concentration 3-4 μg/ml).Tracheal intubation was facilitated with cisatracurium 0.2 mg/kg. The patients were mechanically ventilated.PETCO2 was maintained at 32-38 mm Hg. Anesthesia was maintained with 1%-2% sevoflurane inhalation and intermittent iv boluses of fentanyl and cisatracurium. BIS value was maintained at 40-60. Radial artery was cannulated and connected to continuous cardiac output monitor (Edwards Lifeaciences, USA). ECG, MAP, CVP and SVVtained at 5-7 in group A and 11-13 in group B. Blood loss, urine output and the amount of RBC and plasma infused during operation were recorded. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein (TP), albumin (ALB), total bilirubin ( TBIL), direct bilirubin ( DBIL), blood urea nitrogen (BUN), creatinine (Cr) and lactate and Hb, Hct were measured the day before surgery (baseline) and at day 1,3 and 5 after operation. Results The hemodynamic parameters were maintained within normal limits during operation in both groups. The blood loss, the amount of RBC and plasma infused and urine output during operation were significantly less, while the serum TP and ALB concentrations were higher on the 1st postoperative day in group B than in group A. The serum levels of ALT, AST, TBIL and DBIL were significantly increased and serum concentrations of TP and ALB and Hb,Hct decreased, but there was no significant change in serum BUN and Cr concentrations and lactate after operation as compared with the baseline values before operation in both groups. There were no significant differences in serum levels of ALT, AST, TBIL, DBIL, BUN, Cr, lactate,Hb and Hct after operation between the 2 groups. Conclusion SVV can guide effectively intraoperative fluid restriction in patients undergoing hepatic lobectomy.
RESUMEN
Objective To investigate the effect of psychologic nursing on the rehabilitation for post-stroke depression(PSD) patients. Method 62 patients of 98 PSD patients were divided into 31couples. According to age, sex, course of illness and statge of illness, the patients were divided into rehabilitation nursing ( interference group) and routine nursing ( control group) with CES - D ( Center of epidemi ological survey - depression Scale ) and CNFD ( Criterion of nervous function defect). Every couple was compared with each other. Result The score of two groups before treatment was not obviously different(p＞ 0. 05). Two scores in two groups after treatment were obviously better than those of before treatment. Two scores of interference group were significantly higher compared with control group ( p ＜ 0. 05). Conclusion Interference of psychologic nursing is effective in treating post - stroke depression.
