In the fingertip blood automatic sampling process, when the blood sampling point in the fingertip venous area, it will greatly increase the amount of bleeding without being squeezed. In order to accurately locate the blood sampling point in the venous area, we propose a new finger vein image segmentation approach basing on Gabor transform and Gaussian mixed model (GMM). Firstly, Gabor filter parameter can be set adaptively according to the differential excitation of image and we use the local binary pattern (LBP) to fuse the same-scale and multi-orientation Gabor features of the image. Then, finger vein image segmentation is achieved by Gabor-GMM system and optimized by the max flow min cut method which is based on the relative entropy of the foreground and the background. Finally, the blood sampling point can be localized with corner detection. The experimental results show that the proposed approach has significant performance in segmenting finger vein images which the average accuracy of segmentation images reach 91.6%.

Automatic classification of tuna image needs a good segmentation as a main process. Tuna image is taken with textural background and the tuna’s shadow behind the object. This paper proposed a new weighted thresholding method for tuna image segmentation which adapts hierarchical clustering analysisand percentile method. The proposed method considering all part of the image and the several part of the image. It will be used to estimate the object which the proportion has been known. To detect the edge of tuna images, 2D Gabor filter has been implemented to the image. The result image then threshold which the value has been calculated by using HCA and percentile method. The mathematical morphologies are applied into threshold image. In the experimental result, the proposed method can improve the accuracy value up to 20.04%, sensitivity value up to 29.94%, and specificity value up to 17,23% compared to HCA. The result shows that the proposed method cansegment tuna images well and more accurate than hierarchical cluster analysis method.

Rapid Sampling

A method is described for blood collection from the lateral saphenous vein. This enables rapid sampling, which if necessary can be repeated from the same site without a need for new puncture wounds. The method is a humane and practical alternative to cardiac and retro-orbital puncture, in species where venepuncture has traditionally been regarded as problematic.

The values of haematological and selected blood plasma biochemical parameters of juvenile common carp (Cyprinus carpio Linnaeus, 1758) were compared between blood samples taken from caudal vein and heart to evaluate the influence of blood sampling body site on the obtained results in two groups of fish of different blood sampling order: I – first by caudal and then by cardiac puncture, II – first by cardiac and then by caudal puncture. The obtained results revealed statistically significant (p<0.05) differences only in group I where red blood cell (RBC) count was higher in caudal vein blood, while haematocrit (Ht) value, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), total protein (TP) concentration, and magnesium (Mg) level were higher in cardiac blood samples. No statistically significant differences occurred in white blood cell (WBC) count, differential leukocyte count or erythrocyte morphology based on stained blood smears. The obtained results showed that blood sampling body site may affect the results of haematological and plasma biochemical analyses.

Highlights Results added knowledge on use of midline catheters (MCs) for blood sampling. Using MCs for blood withdrawal resulted in low rates of hemolysis (0.69%). Dwell time was longer in those who had blood drawn from their MC. Nurse practices for blood sampling from MCs varied and learned from other nurses.

Glucose Administration

Background Peripheral blood sampling with heel sticks in neonatescould represent minor invasive procedure which generates pain.The oral glucose administration can reduce the pain in neonatesduring this procedure.Objective To compare the pain sense after oral glucoseadministration or placebo during peripheral blood sampling withheel sticks in neonates.Methods A double blind randomized clinical trial study wasconducted from January to March 2004 in three teaching hospitalsin Medan. The population of this study was divided into twogroups (glucose and placebo) and each group consisted of 32neonates. The intervention group got 1 ml of 40% glucose andthe placebo group got 1 ml of sterile water. Blood sample wastaken with sterile hemolet with heel sticks from healthy atermneonates. The pain was measured using NIPS score and measuredin first 30 seconds after heel sticking. The heart and respiratoryrate measurement was done before and during the interventionand we also counted crying time. Data were analyzed with studentt–test.Results The significant mean difference of NIPS score in glucosegroup was 2.22 (SD 0.83) vs 4.72 (SD 0.96) in placebo group(P<0.0001). There was significant mean difference of crying time,i.e. 0.16 (SD 0.37) in glucose group vs 2.05 (SD 0.77) in placebogroup (P<0.0001). There was significant differences of heart ratebefore and during heel sticking in both groups.Conclusion There were some differences of pain sense in neonateswho received 40% glucose compared to those who received sterilewater during peripheral blood sampling.
