OBJECTIVE To investigate the incidence of bacteria colonization on lumbar epidural catheter tips in postoperative analgesia patients. METHODS The catheter tips were cultured in 100 patients with ASA grade Ⅰ-Ⅱ undergoing lower extremity osteoarticular operation.Lumbar epidural catheters were placed in the operating room with aseptic technique.Diluted local anesthetic and fentanyl infusions were used for postoperative analgesia.The epidural catheter was removed with aseptic technique and the tips sent for microbiological culture after 3 days. RESULTS From 100 patients,bacteriological examination revealed bacteria colonization in 9(9.0%),mainly Staphylococcus epidermidis(6;66.7%),followed by Enterococcus(1;11.1%),Gram-negative bacilli(1;11.1%),and yeasts(1;11.1%).No patient developd infectious complications. CONCLUSIONS Our results show that the risk of bacteria colonization associated with lumber postoperative analgesia in three days is low.No patient develops local or central nervous infection.Epidural postoperative analgesia can be routinely used without worry of infection in epidural space.But we recommend prophylactic measures should be applied in the high-risk groups.

Objective To compare the X-ray features between Hirschsprung alied disease (HAD)and Hirschsprung disease ( HD), and analyze the differentiations. Methods From December 2004 to December 2009, nineteen cases of HAD, aged from 30 days to 10 years (median, 14 months), received barium enema examinations in our institution. Other 19 cases with HD, also received barium enema examinations, were chosen randomly. They were aged from 42 days to 8 years ( median, 8 months). The imaging features of HAD and HD were analyzed retrospectively. The incidence rate of colon stenosis,"truncation sign" and spasm notch and R/C ratio (the longest diameter of rectum/colon) were calculated and compared between these two groups. In all these cases, diagnosis was confirmed by postoperative histopathology. The position of barium retained was also evaluated. These parameters of both groups were compared by x2 and Fisher test. Results There was statistical significance in the incidence rate of colon stenosis between HAD (9/19) and HD (18/19) (x2 = 10.364, P ＜0.01). However, there was no statistical significance in "truncation sign" and spasm notch between HAD (4/19 and 3/19, respectively)and HD ( 1/19 and 1/19, respectively) (P ＞0. 05 for both). R/C ratio was 0. 42 ±0. 15 in HAD group and 0.29±0. 12 in HD group, and there was statistical significance between them (t =2.892,P＜0.01). In HAD group, barium retained in distal sigmoid colon in 1 case (1/19), in distal descending colon in 7 cases (7/19), in distal transverse colon in 1 case (1/19), in total colon in 6 cases (6/19); However, in HD group, barium retained in distal rectum in 3 cases (3/19), in distal sigmoid colon in 13 cases ( 13/19), in distal descending colon in 3 cases (3/19). Conclusions There were some differences in the imaging features between HAD and HD though they presented similar clinic experience. HAD cases presented a lower incidence rate of colon stenosis and a higher R/C ratio than HD cases. In HAD cases, the most common site of barium retained is distal descending colon, while in HD cases, it is distal sigmoid colon.

Objective To observe the effect of application of Lamaze childbirth method in childbirth. Methods The observation group(110 cases)was trained by Lamaze childbirth method in late pregnancy period. The control group (110 cases) was not trained by Lamase childbirth method in antepartum period, and were given regular observation and nursing. Mastering of natural childbirth knowledge, pain intensity, childbirth time, mode of delivery and amount of bleeding post- childbirth 2h were observed in the two groups. Results The observation group mastered more natural birth knowledge than the control group, childbirth pain was obviously reduced, natural birth rate was higher than the control group, the first and second labor time was shorter than the control group, the amount of bleeding was obviously less than the control group 2 hours post childbirth. Conclusions Pregnant women need Lamaze childbirth method training before childbirth and instruction of maternity nurses. These may relieve pain, shorten childbirth time and reduce amount of bleeding post childbirth by application of Lamaze childbirth method.

Objective To analyse the effect of specimen storage time on platelet count in apheresis Donors,in order to choose the appropriate testing time.Methods We choose fifty healthy Unpaid Blood Donors of Platelets to test platelet count in 0,0.5,1,3,6h respectively by the blood counting instrument.Results At room temperature,the count of platelets from blood samples is relatively lower at 0 hour and the difference is significant (P ＜ 0.05).After 0.5-6 hours,the count of platelets become stabilized and not has significantly different(P＞0.05).Conclusion The count of platelets of blood samples is lower at 0 hour than 0.5-6 hours,this work suggest that the count of platelets of blood samples should be done at 0.5-6 h in order to protect platelets quality.
