Drip infusion pyelography by Schencker technique was carried out on total of 20 cases, 7 normal and 13 abnormal. Of 13 abnormal cases, definite diagnosis could be obtained in 1 cases in which conventional urography had not been helpful in establishment of diagnosis, and significant information could be obtained in 6 cases. This is the first report on drip infusion pyelography in this country and no complication was observed during the examination. Drip infusion pyelography was found valuable in cases with the following problems; 1) When valuable information can not be obtained through the conventional urography. 2) When renal function is poor. 3) When delineation of anatomical details is desirable. 4) When retrograde pyelography is contraindicated. Drip infusion pyelography is a safe, new and widely accepted diagnostic procedure in urographic study.

BACKGROUND: The start-up behavior of syringe and syringe pump is known to be one of the causes of inaccurate intravenous infusion. This study evaluated the method of priming the infusion system (PRIMING), and its impact on the target-controlled infusion (TCI) of two remifentanil diluents. METHODS: PRIMING was performed using an evacuation of 2.0 ml to the atmosphere prior to TCI. Forty-eight TCI, using 50 microg/ml (Remi50) or 20 microg/ml (Remi20) of diluents, were performed targeting 4.0 ng/ml of effect-site concentration (Ceff), with PRIMING or not. The gravimetrical measurements of the delivered infusates reproduced actual Ceff. The bolus amount and time to reach 95% target were compared. RESULTS: Without PRIMING, Remi50 infused less bolus (43 +/- 23 %) than Remi20 (19 +/- 9 %) (P = 0.003), and showed more delayed increase of Ceff (11.2 +/- 4.0 min) than Remi20 (7.4 +/- 0.4 min) (P = 0.028). However, PRIMING significantly decreased the deficit of the bolus (2 +/- 1%), as well as the delay of the increase of Ceff in Remi50 (1.2 +/- 0.2 min) (both P < 0.001). In addition, with PRIMING, the start-up bolus showed minimal difference to the nominal bolus (1 and 2%), and Ceff were increased to 4.0 +/- 0.1 ng/ml at the expected time of peak effect, irrespective of the diluents. CONCLUSIONS: Proper operation of the syringe pump used in the priming of the syringe may be helpful in reduction of the inaccuracy of TCI, particularly during the early phase of infusion, or the infusion of a more concentrated diluent.

4.Oral Chemotherapy.
Journal of the Korean Medical Association 2007;50(5):464-470
Most cancer patients present with advanced disease at diagnosis, and a large percentage of those diagnosed with early-stage disease eventually experience recurrence of metastatic disease. Although chemotherapy has recently produced promising results and some progress has been made in the treatment of locally advanced and advanced disease, treatment outcomes and adverse profiles for advanced cancers are still very disappointing. Thus, clinical research on new treatment strategies is warranted. Traditionally, chemotherapy is given by injection. Oral chemotherapy has been developed as a more convenient method of treatment for patients, without the need for cumbersome and uncomfortable injection devices. As oral chemotherapy is taken in the form of a tablet or capsule, it does not need to be injected into the body like other types of chemotherapy. There are many types of oral chemotherapy available for the treatment of different types of cancers. For many patients who are prescribed oral chemotherapy, taking their medication at home is one of the main advantages, as it allows them to live their daily lives without the disruption by hospital visits. In addition, some oral chemotherapy can be more effective and have fewer side effects than conventional chemotherapy. The growing availability of effective oral chemotherapy, especially the new class of 'targeted biologic therapies', is one of the wonderful recent advances in cancer care, as it has given cancer patients unprecedented convenience compared to intravenous infusion therapy. Here, newly developed oral chemotherapy agents and possible approaches to overcome these challenges are discussed.

Purple glove syndrome is a complication of the intravenous infusion of phenytoin. It is characterized by progressive distal edema, discoloration and pain. The mechanism of purple glove syndrome is poorly understood, but the chemical properties of intravenous phenytoin and the extravasation of that are possible causes. We present a woman with purple glove syndrome, whose symptoms were subsided gradually with conservative management.

BACKGROUND: The methods of arrangement of combined intravenous parallel infusions using anti-reflux valve (ARV), with and without anti-syphon valve (ASV) that could decrease occlusion alarm delay were investigated. METHODS: Occlusion challenge tests were mainly performed as bench experiments of four kinds of multiple parallel infusions (10 ml/h and 50 ml/h infusions), which were connected at the proximal or distal portion of ARV, with or without ASV. Alarm threshold was set to 1000 mmHg. Occlusion alarm delays and the compliances of the infusion systems were compared among groups. RESULTS: Without ASV, compared to 10 ml/h infusion alone distal to anti-reflux valve, 50 ml/h infusion distal to anti-reflux valve reduced the mean alarm delay from 416 +/- 7 s to 81 +/- 3 s (P < 0.001). Compared to 50 ml/h infusion alone, combined 10 ml/h and 50 ml/h infusion distal to ARV prolonged the alarm delay from 81 +/- 3 s to 133 +/- 6 s (P < 0.001). However, combined infusions distal to ARV with ASV significantly reduced the alarm delay from 133 +/- 6 s to 74 +/- 5 s (P < 0.001), and also reduced the compliance of the infusion system from 2.31 +/- 0.12 to 1.20 +/- 0.08 microl/mmHg (P < 0.001). CONCLUSIONS: The infusion setup of faster infusion rate, lower compliant system using ASV could effectively decrease occlusion alarm delay during multiple intravenous parallel infusions using ARV.

PURPOSE: The purpose of this study was to examine the effects of structured nursing intervention for caregivers on maintenance of intravenous (IV) infusions in infants. METHODS: The structured nursing intervention was developed through the processes of interviews with nurses from pediatric wards. To identify the effects of the developed nursing intervention, a non-synchronized non-equivalent control group pretest-posttest design study was conducted with caregivers from the pediatric ward from a hospital in Seoul. Of 100 admitted infants, 50 caregivers were assigned to the intervention group and received the structured nursing intervention for maintenance of intravenous infusions in infants. The others were assigned control group and received routine care. Data were collected on patient factors, IV insertion factors, treatments, and IV related complications. The form developed for the structured nursing intervention was used by staff nurses. RESULTS: Compared to the control group, IV insertion frequency in experimental group infants was significantly lower and IV related complications decreased (p<.05). CONCLUSION: These results suggest that the structured nursing intervention for caregivers on maintenance of intravenous infusions may have effects on maintenance of intravenous infusions in infants, and decreasing IV related complications. This nursing intervention can be used to improve IV related problems of admitted infants.

BACKGROUND: In dental intravenous sedation, continuous intravenous infusion of a low-dose drug requires an infusion pump such as a syringe pump. To develop a new syringe pump for clinical use, the functions of the pump must meet certain international standards. Various safety and efficacy tests must be performed on the syringe pump, as stipulated by these standards, and an approval must be received from the approving agency based on such test results. METHODS: The authors of the present study developed a novel syringe pump and performed efficacy evaluation by testing its infusion speed at 1 and 25 ml/h, and infusion performance testing at 2 and 24 h. Moreover, performance evaluation was conducted by comparing the novel pump to an existing pump with the infusion speed varied from 1 to 5 ml/h. RESULTS: In the efficacy testing on the newly developed syringe pump, infusion with the infusion speed initially set to 1 ml/h resulted in infusion speeds of 1.00 and 0.99 ml/h in the 2- and 24-h assessment, respectively. Changing the infusion speed setting to 25 ml/h resulted in an infusion speed of 25.09 and 23.92 ml/h in the 2- and 24-h assessment, respectively. These results show no significant differences when compared with other commercially available pumps. CONCLUSIONS: The efficacy testing of the newly developed syringe pump showed the accuracy to be within tolerance. Based on these findings, we believe that the newly developed syringe pump is suitable for clinical use.

PURPOSE: To determine the effect of iron on proton MR spectra (1H-MRS) by evaluating changes in 1H-MRS of the liver according to changes in hepatic parenchymal iron content. MATERIALS AND METHODS: We evaluated serial changes in 1H-MRS of the liver after intravenous infusion of SPIO in 40 rabbits. These were divided into eight groups of five, and in each group, respectively, 1H-MRS and T2WI MR images were acquired prior to SPIO infusion, just after infusion, and at 15 minutes and 1, 2, 4, 24 and 96 hours after infusion. MR spectra were evaluated with particular attention to the curve pattern observed at specific times after the infusion of SPIO, and the results were correlated with the signal intensity observed on T2W1 images and the histologic giade of ilon content of samples of resected liver parenchyma. RESULTS: As observed on T2WI, the mean signal intensity of rabbit liver in its pre-SPIO infusion state, just after infusion, at 15 minutes, and at 1, 2, 4, 24 and 96 hours after SPIO infusion was 121.3 +/-15.5, 41.5 +/-12.7, 30.3 +/-7.9, 31.3 +/-3.5, 33.6 +/-9.4, 45.5 +/-10.9, 80.3 +/-15.7 and 110.4 +/-22.9, respectively(p<0.05). Mean standard deviation of the ratio of the area of the peak (3.9-4.1 ppm) / lipid peak (1.3 ppm) peak at each of the above times except for the pre-infusion state was 1.10 +/-0.13, 1.86 +/-0.21, 1.80 +/-0.30, 1.76 +/-0.27, 1.74 +/-0.20, 0.07 +/-0.02 and 0.03 +/-0.01, respectively(p<0.05). The hepatic parenchymal iron content increased rapidly from just after SPIO infusion, reaching its maximal level (as revealed by histologic specimens) at 15 minutes, sustaining this for up to 4 hours, and then decreasing gradually over periods of 24 and 96 hours. These results show that serial changes in patterns of MR spectra and the signal intensity seen on T2WI images correlate closely with changes in hepatic parenchymal iron content. CONCLUSION: Elevated hepatic parenchymal iron content leads to increases in the relative intensity of unknown peaks at around 4.0 ppm and decreases in the relative intensity of lipid peaks.

10.Study on postoperative infusion management of cleft patients.
West China Journal of Stomatology 2016;34(4):387-390
OBJECTIVEThe study aims to investigate the correlation between total input for a period of 24 h and the daily physiological requirements to develop practical guidelines for postoperative infusion management of cleft patients.
METHODSSixty-three cleft lip and palate patients under three years old who underwent surgery were included in the study. The amount of liquid taken orally as well as intravenous input were recorded for a period of 24 h and compared with the daily physiological requirements. Based on the comparison results, the amount of intravenous infusion was adjusted to match the physiological requirements. Eighty-one patients under one year old were also included to evaluate the effectiveness of the adjustment. The amount of liquid taken orally and intravenous inputs were also recorded and the correlation between total input and urine output analyzed.
RESULTSThe total input of the first group of patients significantly exceeded the physiological requirements. After adjustment, the liquid intake remained at the same level, but the total intake moved closer to the physiological requirements. Statistically significant correlations were observed between liquid taken orally and intravenous intakes, and between total intake and urine formation.
CONCLUSIONSMore precise management of postoperative infusion is necessary for cleft patients. For patients less than six months old, the amount of intravenous infusion should be around 60% of the physiological requirements, whereas that for patients between six months and one year should be around 75%.
