Background: One in five patients admitted to the hospital treated with intravenous (IV) fluid therapy suffer complications due to inappropriate administration. Errors have been reported in 13–84% of the preparation and administration of IV medications. The safe delivery of IV fluids requires precise rate administration. Objectives: This systematic review aims to determine the accuracy of infusion sets and devices and examine the factors that affect the flow rate accuracy of devices. Data Sources and Methods: Six databases (CINAHL, MEDLINE PubMed, EMBASE, Web of Science and Cochrane Database of systematic reviews) were systematically searched. Search terms included infusion pumps, infusion devices, flow rate accuracy, fluid administration rate, gravity-led infusion set and fluid balance. Studies were included if they examined infusion devices’ flow rate accuracy and drop rates for fluids or non-oncological drugs. Findings were tabulated and synthesised qualitatively. The quality of the studies was examined based on the design of the studies due to their heterogeneity. Results: Eight studies were included: Four studies were conducted on human subjects in the hospital environment; studies recruited 182 participants between the ages of 18 and 94 years. Two studies examined flow rate accuracy in recruited patients across 509 observations and 2387 drip hours. No trials prospectively assessed the accuracy of infusion pumps in the clinical domain, and no studies were reported on patient safety outcomes. Four studies examined the impact of mechanical and physiological factors on the flow rate accuracies of infusion devices. Height and back pressure simulated vibrating conditions, the viscosity of IV fluid and the positions of patients were reported to have a significant impact on infusion volume and flow rates of infusion devices. Additionally, giving sets that vary from the manufacturer’s specifications are reported to increase error percent by 10–20%. Conclusion: Infusion devices are an important source of error in administering IV fluids. Yet, there needs to be more prospective trial data to support their clinical accuracy and the impact on patient outcomes. Future flow variability and accuracy studies should capture their impact on patient safety and clinical outcomes.

“…Berbagai perangkat infus telah diperkenalkan untuk pemberian cairan intravena. Meskipun pengendali dropcounting yang diberi makan gravitasi telah digunakan secara luas untuk infus cairan, keakuratannya tidak optimal [4]. Pompa infus memberikan cairan, obat atau nutrisi ke dalam sistem sirkulasi pasien.…”

Dalam dunia medis infus merupakan alat yang paling sering digunakan, fungsi infus sendiri yaitu untuk memberikan cairan kepada pasien secara berkala. Kesalahan dalam pemberian cairan infus dapat berakibat buruk kepada pasien, juga apabila terjadi masalah seperti penyumbatan atau kehabisan cairan jika tidak segera ditangani akan berbahaya bagi pasien. Infus yang ada saat ini penggunaannya masih secara manual dimana kesalahan - kesalahan seperti tersebut masih sering terjadi, oleh karena itu dalam penelitian ini membuat infus yang dapat bekerja secara otomatis serta dipantau dari jarak jauh. Pada penelitian ini membuat pengatur infus berbasis mikrokontroller yang dapat di monitoring secara berkala menggunakan handphone yang sistem kerjanya seperti Internet of Thing karena dalam memonitoring perangkat dan aplikasi android tersambung dengan internet, serta dapat diatur menggunakan button yang berguna untuk memasukan jumlah tetesan infus. Sensor yang digunakan pada alat ini infrared transmitter dan infrared receiver berdiameter 5mm dan untuk pendeteksi detak jantung menggunakan MAX30100 sebagai feedback dari pasien. Sedangkan sebagai penekan selang menggunakan motor stepper 28byj-48 dengan konfigurasi half-step. Mikrokontroller menggunakan ESP8266 sebagai kontrol motor servo serta mengirim data ke cloud. Oled 9,6” dan Button digunakan sebagai interface. Hasil yang didapat dari pengujian untuk mengatur jumlah tetesan infus tiap menit memiliki tingkat total rata – rata error 5,59%. Sedangkan hasil pengujian untuk pendeteksian detak jantung memiliki nilai total rata – rata error 5,57% dan memiliki rata-rata delay dalam pengiriman maupun penerimaan data sebesar 59,6 microsecond.

“…[28,34] Actual flow rates, measured gravimetrically were less due to catheter configuration flow resistance. [35] Aorta and internal carotid artery (ICA) flow were maintained at 3,500 ± 200 ml/min and 240 ± 30 ml/min, respectively. Two catheter configurations were used, single catheter and two coaxial catheters and two IV bag configurations were chosen, insulated and noninsulated.…”

Infusion warm during selective hypothermia in acute ischemic stroke

et al. 2019

INTRODUCTION:Mechanical thrombectomy (MT) has dramatically improved the prognosis for acute ischemic stroke (AIS) patients. Despite high recanalization rates, up to half of the patients will not present a good neurological outcome after MT. Therapeutic hypothermia is perhaps the most robust neuroprotectant studied preclinically. MATERIALS AND METHODS:We explored various warming effects that can reduce the effectiveness or potency of selective hypothermia during AIS under conditions similar to actual clinical care. Four different selective hypothermia layouts were chosen. Layouts 1 and 2 used a single catheter without and with an insulated IV bag. Layouts 3 and 4 used two catheters arrange coaxially, without and with an insulated IV bag. Independent variables measured were IV bag exit temperature, catheter inlet temperature, and catheter outlet temperature at four different flow rates ranging from 8 to 25 ml/min over an infusion duration of 20 min.RESULTS: Dominant warming occurs along the catheter pathway compared to warming along the infusion line pathway, ranging from 66% to 72%. Coaxial configurations provided an approximate 4°C cooler temperature benefit on delivered infusate over a single catheter. Brain tissue temperature predictions show that the maximum cooling layout, Layout 4 at maximum flow provides a 1°C within 5 min. CONCLUSION:Significant rewarming effects occur along the infusate flow path from IV bag to site of injury in the brain. Previous selective hypothermia clinical work, using flow rates and equipment at conditions similar to our study, likely produced rapid but not deep tissue cooling in the brain (~ 1°C).
