ObjectiveTo explore the causes and countermeasures for extravasation of intravenous fluids in children. Methods726 cases of intravenous infusion in pediatric surgery department from May to December 2011 in our hospital were observed. ResultsThere were 30 cases with extravasation of intravenous infusion in the 726 cases,the leakage rate was 4.13％.The specific causes of fluid extravasation included:younger age of children,not cooperating with the infusion in 18 cases,accounting for 60.00％,followed by non standardized fixation methods in 5 cases,accounting for 16.67％,and accompanying family members refused to be disturbed accounted for 13.33％,Nursing visits to owe in a timely manner accounted for 6.67％.The rate of younger age of children and lack of cooperation leading to fluid extravasation were significantly higher than other causes,the difference was statistically significant. ConclusionsChildren age,fixation method,cooperation of family members,inspections and other factors can be controlled.Along with the continuous improvement of medical standards and a variety of active and effective implementation of the measures,these factors can be controlled effectively.Strengthening the training of nurses and vocational skills to enhance their own sense of responsibility,to give standardized infusion operation and fixation,and give predictable observation and treatment,can effectively prevent the occurrence of extravasation of intravenous fluids.

Objective To explore the role of remote ischemic preconditioning(RIPC)in prevention of contrast -induced nephropathy(CIN)in elderly patients undergoing coronary artery angiography(CAA).Methods 106 elderly patients were enrolled in this randomized control trial.According to random number table,the patients were randomized into control group (n =53)and RIPC group(n =53).All of the patients received 1 000mL of 0.9% sodium chloride injection before CAA.The RIPC group patients underwent RIPC in their right arms with sphygmomanometer cuff infla-tion for 5 minutes prior to the CAA,three cycles were repeated.Serum creatinine was detected before and 48 hours after CAA.Results CIN was reported in 10 cases in the control group and 3 cases in the RIPC group(χ2 =4.30, P =0.04).The levels of serum creatinine were increased[(96.38 ±9.50)μmol/L vs (88.87 ±10.24)μmol/L] after CAA in the control group(t =2.28,P =0.03),and there was no difference in the RIPC group(t =1.17,P =0.24).Conclusion RIPC has a protective effect on CIN in elderly patients in our study.Since this method is harm-less and cost effective,further studies is required to popularize PIPC to our clinical practice for prevention of CIN.

OBJECTIVETo explore the effect and safety of topical propranolol hydrochloride gel for treatment of infantile hemangioma. METHODS Thirty nude mice (BALA/c, nu/nu) were divided into three groups, experimental group, control group and normal group. Human hemangioma endothelial cells cultured in vitro were injected subcutaneously in experimental group and control group to establish infantile hemangioma model. Topical propranolol hydrochloride gel was applied on the surface of the hemangioman in experimental group and normal group. Tumor volumn change and the skin situations (edema, erythema, ulceration) were observed at different periods. 45 days after cell injection, the mice were killed and plasma concentration was detected in the experimental group and the control group by high performance liquid chromatography with evaporative light scattering detector, and tumors were subjected to histopathologic examination and immunohistochemistry for CD31 and CD34. The correlation between volumes and plasma concentration was statistically analyzed with SPSS 13.0 paired samples t test with α = 0.05 as statistical standard.

RESULTSAt 45 days, the volume of the tumor in control group was (366.57 ± 17.08) mm³, which has a significant difference as compared to the experimental group (13.36 ± 2.09) mm³ (P < 0.05); and the plasma concentration was (16.83 ± 1.53) ng/ml in experimental group, and (18.42 ± 2.21) ng/ ml in normal group (P > 0.05 ). Topical propranolol hydrochloride gel (3%) has no irritation to nude mice's skin.

CONCLUSIONSTopical application of 3% propranolol hydrochloride gel is effective and safe for the treatment of infantile hemangioma.

OBJECTIVETo investigate the effect of topical propranolol gel on the levels of plasma vascular endothelial growth factor (VEGF), basic fibroblastic growth factor (bFGF) and matrix metalloproteinases-9 (MMP-9) in proliferating infantile hemangiomas (IHs) of superficial type.

METHODS33 consecutive children with superficial IHs were observed pre-treatment, 1 and 3 months after application of topical propranolol gel for the levels of plasma VEGF, MMP-9 and bFGF by enzyme-linked immunosorbent assay (ELISA) in Department of General Surgery of Dongfang Hospital from February 2013 to February 2014. The plasma results of IHs were compared with those of 30 healthy infants. The clinical efficacy in IHs was evaluated by Achauer system. Differences of plasma results between the healthy group and the IHs group pre-treatment were analyzed using Mann-Whitney U-test. Paired sample comparisons of any two time points of pre-treatment, 1 month and 3 months after treatment in IHs were evaluated by Wilcoxon signed-rank test.

RESULTSThe clinical efficiency of topical propranolol gel at 1, 3 months after application were 45.45%, 81.82% respectively. The levels of plasma VEGF and MMP-9 in patients pre- treatment were higher than those in healthy infants [(362.16 ± 27.29) pg/ml vs (85.63 ± 8.14) pg/ml, (1376.41 ± 42.15) pg/ml vs (687.27 ± 44.1) pg/ml, P < 0.05], but the level of bFGF did not show significant difference [(176.03 ± 13.60 ) pg/ml vs (235.94 ± 35.43 ) pg/ml, P > 0. 05 ]. The concentrations of VEGF and bFGF at 1, 3 months after treatment decreased obviously [(271.51 ± 18.59) pg/ml vs (362.16 ± 27.29 ) pg/ml, (135.85 ± 12.66) pg/ml vs (176.03 ± 13.60) pg/ml], 1 month after treatment vs pre-treatment, P < 0.05; (240.80 ± 19.89) pg/ml vs (362.16 ± 27.29) pg/ml, (107.31 ± 5.82) pg/ml vs (176.03 ± 13.60) pg/ml, 3 month after treatment vs pre-treatment, P < 0.05, whereas the levels of plasma MMP-9 declined slightly [(1321.18 ± 48.74) pg/ml vs (1376.41 ± 42.15 ) pg/ml, (1468.68 ± 32.78) pg/ml vs (1376.41 ± 42 2.15 ) pg/ml, P > 0.05 ].

CONCLUSIONSPropranolol gel may suppress the proliferation of superficial infantile bemangiomas by reducing VEGF and bFGF.
