No single infusion system is ideal for delivery of all drugs in all institutions for all patients. For example, a syringe pump with microbore tubing may be preferred for the infusion of vancomycin to neonates. Each facility must be cognizant of problems of drug delivery and develop specific guidelines for intravenous infusions. 

The short lived positron-emitter Rb-82 (t 1/2=1.26m) has potential application in cardiovascular diagnostic nuclear medicine. A generator system containing the parent Sr-82 has been developed that will provide an eluate of Rb-82 suitable for direct infusion. The Rb-82 is eluted by a syringe pump from a hydrous stannic oxide column in a continuous stream of physiological saline solution. The rate of elution (infusion) can be controlled from 10 to 100 ml/ min. At elution rates of 25, 50, and 75 ml/min,...

Fig. 6.5 Diagram of system set-up for postcolumn infusion test for matrix effect. The analyte in the mobile phase was infused by a syringe pump at about 10 pL/min. The blank matrix extract or the test control (mobile phase or water blank extract) was injected into the analytical column. The effluent from the analytical chromatographic column was mixed...

An infusion control device (ICD) is a device that maintains a constant infusion rate in a gravity flow system (controller) or via a positive pressure pump. A positive pressure pump is a device that provides mechanical pressure (2-12 psi) to overcome the resistance to flow in the vessels. The types of positive pressure pumps are categorized according to how they deliver the solution and their degree of precision in the flow rate. Positive pressure pumps include peristaltic pumps, cassette pumps, syringe pumps, non-electiic or disposable pumps, and patient-controlled analgesic... 

Drugs may require i.v. administration as continuous infusions or at intervals (q4h, q6h, ql2h, etc.). Manual methods require the administration of the drug into the i.v. system at an injection site (Y-site, T-connector, stopcock, etc.), added to the i.v. solution in a mixing chamber, or added to an i.v. bag to be administered via gravity. A syringe pump or another mechanical device may be used for drug administration. 

Methods of extraction and analysis have been published by the Association for the Advancement of Medical Instrumentation [12]. Water or other aqueous systems are most commonly used for extraction. Two extraction methods are lecammaxled, exhaustive extraction and simulated use. In fact both methods, if used correctly, represent simulated use. Exhaustive extraction is recommended for devices such as implants, which by merit of their prolonged contact with tissue over time can be expected to transfer all of their residual ethylene oxide to the recipient. Simulated use extraction of a less exhaustive nature might include fluid path extraction over a simulated maximum hold period for infusion sets and hypodermic syringes. Analysis is by gas chromatography. 

Fig. 3. We use an oil-filled injection system for the nuclear transplantations. The syringe and tubing are filled with mineral oil and the infusion pump depresses the syringe plungw, resulting in a constant, desirable flow rate.
