Background:
Since a micro-infusion pump continuously pumps drugs at a low speed, it has the risk of complications including venous blood return, indwelling needle blockage, and the lack of regular delivery of drugs. This study aimed to investigate venous blood return and indwelling needle blockage after cardiac surgery when a micro-infusion pump was used at a very low flow rate of only 2 ml/h without any accompanying fluid.
Methods:
A total of 215 patients, who were hospitalized at the Second Hospital of Shandong University between May and December 2020, received a continuous intravenous administration of drugs via a micro-infusion pump at 2 ml/h without or with accompanying fluid. These patients were randomly divided into an observation group (108 patients) and a control group (107 patients). In the observation group, drugs were administered at 2 ml/h without any additional fluid. In contrast, the control group received drugs also at 2 ml/h but with a normal saline through an intravenous drip. The venous backflow, blockage of the indwelling needle and catheter, and other adverse reactions were evaluated In addition, the volume of an accompanying fluid as well as the mean of nursing work time and additional costs were calculated.
Results:
The main finding of this analysis showed no statistically significant differences in the number of complications such as venous backflow, blockage of the indwelling needle or catheter, or any adverse reactions between the observational and control groups (P > 0.05). Compared to the control group, the observation group had significantly reduced the amount of fluid intake (P< 0.001). In addition, the 2 ml/h infusion tempo without any additional fluid shortened nursing hours (P < 0.001), and thus reduced costs for the observation group vs. the control group.
Conclusions:
It is feasible and safe to administer drugs via a micro-infusion pump at the slow 2 ml/h tempo without any accompanying fluid to patients after surgery requiring minimal volume of fluids.
Insights
Administering drugs via micro-infusion pump at 2 ml/h without accompanying fluid is safe for post-cardiac surgery patients. This method reduces fluid intake, nursing time, and costs without increasing complications like venous backflow or needle blockage.
Area of Science:
- Medical Devices
- Postoperative Care
- Intravenous Infusion Therapy
Background:
- Micro-infusion pumps offer continuous drug delivery at low rates.
- Potential complications include venous blood return issues, needle blockage, and irregular drug delivery.
- This study focuses on risks associated with a 2 ml/h infusion rate without accompanying fluid post-cardiac surgery.
Purpose of the Study:
- To evaluate the safety and efficacy of micro-infusion pump use at 2 ml/h without accompanying fluid.
- To compare complication rates (venous backflow, needle blockage) between groups receiving infusion with and without accompanying fluid.
- To assess associated fluid volume, nursing workload, and costs.
Main Methods:
- A randomized controlled trial involving 215 post-cardiac surgery patients.
- Observation group received drugs at 2 ml/h without additional fluid.
- Control group received drugs at 2 ml/h with normal saline infusion.
- Evaluated venous backflow, needle/catheter blockage, and adverse reactions.
Main Results:
- No significant differences in venous backflow, needle/catheter blockage, or adverse reactions between groups (P > 0.05).
- The group without accompanying fluid had significantly reduced fluid intake (P < 0.001).
- Infusion without fluid shortened nursing hours (P < 0.001) and reduced costs.
Conclusions:
- Administering drugs via micro-infusion pump at 2 ml/h without accompanying fluid is feasible and safe.
- This approach is suitable for patients requiring minimal fluid volumes post-surgery.
- The method offers benefits in reduced fluid load, nursing time, and cost savings.
