OBJECTIVE: Analyze and conclude the new quality control process, so as to improve the quality control efficiency. METHODS: Statistical analysis was conducted on the flow rate quality control data of infusion pump in 2020, with a total of 330 times of quality control data. RESULTS: The pump with qualified flow rate entered and maintained the qualified state from the third minute, while the pump with unqualified flow rate entered and maintained the unqualified state from the second minute. CONCLUSIONS Take the third minute to enter the qualified range and continue for 2 minutes to judge that the flow rate quality control is qualified. The accuracy of this new rule is as high as 100%, and the time of flow rate quality control can be reduced from 60 minutes to 10 minutes, which greatly improves the work efficiency.

OBJECTIVE: To compare the clinical outcomes of hydraulic perfusion pump and traditional water fhushing in percutaneous endoscopic lumbar discectomy. METHODS: From January 2016 to December 2018, 72 patients with lumbar disc herniation failed to conservative treatment were enrolled in this study. The patients were divided into hydraulic perfusion pump group and traditional water flushing group, 36 cases in each group. There were no significant differences in gender, age, prominent segment, clinical classification, preoperative visual analogue scale (VAS) and Japanese Orthopaedic Association(JOA) score between two groups ( RESULTS: All the patients were followed up for 12 to 24 (15.7±5.1) months. Compared with the traditional water flushing group, the operation time of the hydraulic perfusion pump group was shorter [(65.5±21.3) min vs (74.8±19.9) min, CONCLUSION Both hydraulic perfusion pump and traditional water flushing assisted percutaneous endoscopic lumbar disc herniation can achieve satisfactory clinical results, but the former has shorter operation time, clearer intraoperative vision, less bleeding, and fewer intraoperative and postoperative complications.

infusion pump may transiently interrupt drug administration and result in medication errors. A newly developed infusion device (Anyfusion®) that combines the functions of an infusion pump and a syringe pump in a single unit was recently commercialized. This study compared the operator workloads associated with the Anyfusion® pump and with the conventional method using two infusion devices (a syringe pump and an infusion pump).METHODS: This was a prospective, randomized, crossover-designed simulation study using an imitation arm with an intravascular line. We compared the two methods in terms of total execution time, total number of button clicks, and subjective difficulty using a numerical rating scale with a score from 0 (extremely easy) to 10 (extremely difficult).RESULTS: Twenty-two nurses successfully performed both interventions according to the allocated sequence. Total execution times did not differ between the two methods (129.5 ± 23.2 seconds for the conventional method vs. 121.2 ± 24.3 seconds for the Anyfusion® method; P = 0.244), although the total number of clicks was significantly fewer using the Anyfusion® than the conventional method (median [interquartile range]: 10.0 [9.0–12.0] vs. 21.0 [20.0–25.0], respectively; P < 0.001). Participants rated the Anyfusion® method as easier than the conventional method (1.7 ± 1.2 vs. 3.6 ± 1.6; P < 0.001, respectively).CONCLUSION: The introduction of Anyfusion® lessened the workload of practitioners required by the changeover process, which might reduce the risk of medication errors and subsequent patient harm.TRIAL REGISTRATION: Clinical Research Information Service Identifier: KCT0004172]]>

BACKGROUND: Hypertonic saline (HS) injections for decompressive neuroplasty (DN) can cause pain. We assessed whether a continuous infusion of HS through an infusion pump would reduce injection-related pain compared with repeated bolus administrations. METHODS: Fifty patients scheduled for DN were randomized to either the bolus injection or the continuous infusion group. After appropriately placing the epidural catheter, 4 mL of 5% NaCl was injected as four boluses of 1 mL each at 15-minute intervals or infused over 1 hour using an infusion pump. The severity of pain induced by HS injection, as measured by the 11-point numerical rating scale (NRS), was the primary outcome. The severity of low back or lower extremity pain, as measured by the 11-point NRS and Oswestry Disability Index (ODI), 3 months following the procedure, was the secondary outcome. RESULTS: Data from 21 patients in the bolus group and 23 in the continuous infusion group were analyzed. No statistically significant difference in injection-related pain was identified between the two groups during the initial HS administration (P = 0.846). However, there was a statistically significant reduction in injection-related pain in the continuous infusion group compared to the bolus injection group from the second assessment onwards (P = 0.001, < 0.001, and < 0.001, respectively). No significant between-group differences in the NRS and ODI scores 3 months post-procedure were noted (P = 0.614 and 0.949, respectively). CONCLUSIONS: Our study suggests that administering HS through a continuous infusion is a useful modality for reducing HS injection-related pain during DN.

By providing blood glucose (BG) concentration measurements in an almost continuous-time fashion for several consecutive days, wearable minimally-invasive continuous glucose monitoring (CGM) sensors are revolutionizing diabetes management, and are becoming an increasingly adopted technology especially for diabetic individuals requiring insulin administrations. Indeed, by providing glucose real-time insights of BG dynamics and trend, and being equipped with visual and acoustic alarms for hypo- and hyperglycemia, CGM devices have been proved to improve safety and effectiveness of diabetes therapy, reduce hypoglycemia incidence and duration, and decrease glycemic variability. Furthermore, the real-time availability of BG values has been stimulating the realization of new tools to provide patients with decision support to improve insulin dosage tuning and infusion. The aim of this paper is to offer an overview of current literature and future possible developments regarding CGM technologies and applications. In particular, first, we outline the technological evolution of CGM devices through the last 20 years. Then, we discuss about the current use of CGM sensors from patients affected by diabetes, and, we report some works proving the beneficial impact provided by the adoption of CGM. Finally, we review some recent advanced applications for diabetes treatment based on CGM sensors.

PURPOSE: This study aimed to investigate the clinical alarm occurrence and management of nurses toward clinical alarms in the intensive care unit (ICU). METHODS: This observational study was conducted with 40 patients and nurses cases in two ICUs of a university hospital. This study divided 24 hours into the unit of an hour and conducted two times of direct observation per unit hour for 48 hours targeting the medical devices applied to 40 patients. Data were analyzed using IBM SPSS Statistics 23. RESULTS: On average, 3.8 units of medical devices were applied for each patient and the ranges of alarm settings were wide. During 48 hours, 184 cases of clinical alarm were occurred by four types of medical devices including physiological monitors, mechanical ventilators, infusion pumps, and continuous renal replacement therapy. Among them, false alarm was 110 cases (59.8%). As for the alarm management by ICU nurses, two-minute alarm mute took up most at 38.0% (70 cases), and no response was second most at 32.6% (60 cases). When valid alarm sounded, nurses showed no response at 43.2%. CONCLUSION: The findings suggest that a standard protocol for alarm management should be developed for Korean ICU settings. Based on the protocol, continuous training and education should be provided to nurses for appropriate alarm management.

Medical injection pump is a commonly used clinical equipment with high risk. Accurate detection of flow is an important aspect to ensure its reliable operation. In this paper, we carefully studied and analyzed the flow detection methods of three standards being used in medical injection pump detection in our country. The three standards were compared from the aspects of standard device, flow test point selection, length of test time and accuracy judgment. The advantages and disadvantages of these standards were analyzed and suggestions for improvement were put forward.

BACKGROUND: Hypothermia is a common physiological condition that occurs during surgical operations. The goal of this experiment is to measure the temperature of the fluids flowing through heated breathing circuits with respect to changes in infusion speed. METHODS: The infusion pump was connected to the intravenous inlet of a heated breathing circuit with two 50 cm extension lines connected to the outlet. Fluids were injected through the heated breathing circuit at 100, 200, 300, 400, 500, 600, and 700 ml/h, with measurement of the fluid temperature immediately after transit (OP 20), 70 cm after transit (OP 70), and 120 cm after transit (OP 120). RESULTS: The mean fluid temperatures at OP 20, OP 70, and OP 120 were 40.7 ± 4.8℃, 35.1 ± 3.22℃, and 31.7 ± 2.5℃, respectively. CONCLUSIONS: The heated breathing circuit was effective to heat the fluid. After passing out the heated breathing circuit, the temperature of the fluid continuously reduced. A length of 70 cm can be used to efficiently supply heated fluid to the patient. From this experiment, it is expected that supplying heated fluid to a patient using the heated breathing circuit will help maintain the patient's body temperature.

PURPOSE: Insulin pumps are widely used in diabetes. They are equipped with safety alarms to alert users. Pump manuals contain alarm codes and how to troubleshoot them. However, these manuals are lengthy and difficult to use, particularly in emergencies. We aim to assess the impact of targeted education on warnings and errors in improving competency to troubleshoot the alarms. METHODS: Twenty-one patients, with a median age of 13, were recruited over a 5-month period. Each patient had 2 study visits. The frequencies and types of alarms were recorded, and patients were given a summary sheet that outlined common alarms encountered and troubleshooting tips. In visit 2, the frequencies and types of alarms were compared to those of visit 1. The patients were asked to fill a questionnaire and to rate the education session given in visit 1, their level of competency in decrypting alarm codes, and their promptness in responding to alarms. RESULTS: Low cartridge (W1), low battery (W2), and bolus cancelled (W8) were the commonest warnings. The most noted errors were occlusion (E4), power interruption (E8), empty battery (E2), set not primed (E11), and cartridge empty (E1). The numbers of warning and error signals markedly decreased after targeted education (P < 0.05). The ability in decrypting warning signals significantly improved (P=0.02), and the frequency of response to pump alarms significantly increased (P=0.001). CONCLUSION: Certain warnings and errors are more common than others in insulin pumps. Targeted education is useful in improving competency and response of patients in managing pump alarms.
