“…Furthermore, the peak pressure of the pump cycle will be damped by the compliance of the venous plexus . Evidence to back these assumptions comes from an experiment that used a similar cyclical pump (Manual Bulb Pump; Tuta laboratories, Lane cove, NSW, Australia) infusing via a 16‐G cannula into a forearm vein .

The properties of an improvised piston pump for the rapid delivery of intravenous fluids

SummaryTo maximise the effect of a small fluid load, it is occasionally desirable to bolus manually with multiple depressions of a large-capacity syringe. This is usually achieved by placing the syringe on the side port of a three-way tap. We modified this technique by placing two-one-way valves in line with the three-way tap, effectively creating a piston pump, the infusion rates via which we compared with those achieved by an inflatable pressure-infuser in a simulated resuscitation. Fluid flow was faster using the piston pump than with the pressure-infuser (mean (SD) time to infuse 2000 ml saline 0.9% via a 16-G cannula 352 (10) s vs 495 (19) s, respectively, p < 0.0001). The piston pump appears to have potential for both tight control of fluid delivery and major high-volume resuscitation. The lightweight nature of the pump and its lack of reliance on gravity may also make it suitable for the pre-hospital setting.

“…However, there have been some case reports of extravasation and compartment syndrome resulting from pressurized infusion [3][4][5][6]. Moreover, even if the cannula is placed appropriately in a vein and the proximal run-off from the vein is occluded, the venous pressure can increase markedly [11]. Thus, intravenous sites should be checked closely if using both the piston-pump and pressure-infusor methods.…”

Background The piston-pump method is a simple method for rapid administration of fluids. However, some problems regarding effectiveness in increasing the flow rate of fluid administration, occurrence of excessive pressure in the infusion circuit and vessel, and bacterial contamination of fluids are unsolved. We compared the effectiveness of using the piston-pump method with that of the pressureinfusor method.Methods Twelve anesthesiologists were classified randomly into the piston-pump and pressure-infusor groups. They were asked to infuse 500 ml of 0.9% saline three times successively through a 16-G intravenous cannula as rapidly as possible using a pump with a 50-ml syringe or a pressure-infusor at 300 mmHg. The time taken for infusion, the pressure in the infusion circuit and substitute vessel, and bacterial contamination were examined. ResultsThe infusion time (mean ± SD) in the pressure-infusor and piston-pump groups was 233 ± 19 s and 301 ± 48 s, respectively (P < 0.01). There was a significant difference in the infusion time at the first and third attempts of infusion only in the piston-pump group (P < 0.05). The pressure (in mmHg) in the circuit was 131 ± 9 and > 200 (P < 0.01) and in the substitute vessel was 5 ± 1 and 17

“…Some degree of wear and tear may have occurred, leading to stretching and possible greater distension of the veins, which potentially would result in a higher failure rate in constructs tested later because of the larger circumference of the distended vessel. In a human cadaveric study, Goodie showed that thin‐walled veins are resistant to high luminal pressures (>800 mm Hg); therefore, it is unlikely that much damage occurred with distension to 100 mm Hg . The potential effect of the order in which the tests were performed for each vessel was adjusted for in the statistical analysis, and the tests were performed in a random order to attempt to minimize the effect of this limitation on the results.…”

Evaluation of different methods of securing cellophane bands for portosystemic shunt attenuation

et al. 2018

Objective: To compare mechanisms of and pressures at failure of 4 methods of securing 2 types of cellophane bands around a vein. Study design: Ex vivo mechanical evaluation. Methods: Cellophane bands composed of 3 or 4 layers were applied around a cadaveric external jugular vein (EJV) to create 25% or 50% attenuation. These bands were secured with a medium or medium-large polymer locking ligation clip (PLLC), or a medium or medium-large titanium ligation clip (TLC). Sterile saline 0.9% was instilled into the lumen of the EJV until a pressure of 100 mm Hg was reached. Failure mechanism and luminal pressure at failure were compared between groups. Results: Medium clips failed less often than medium-large clips (P < .001) and consistently sustained 100 mm Hg without failing. Three-layer cellophane bands were 4.1 times more likely to fail than 4-layer bands (P = .003, CI 1.6-10.2) and failed at lower pressures (28.32 ± 3.59 mm Hg and 44.81 ± 6.51 mm Hg, respectively, P = .027). Failure rates of the cellophane band constructs did not differ whether secured with PLLC or with TLC (P = .635) or with 25% vs 50% attenuation (P = .780). Conclusion: A single medium clip withstood physiological forces and secured a cellophane band at up to 50% attenuation. A 3-layer cellophane band was more likely to fail compared with a 4-layer cellophane band. Clinical significance: These ex vivo results provide evidence to support the application of a 4-layer cellophane band secured with a single medium PLLC or TLC for portosystemic shunt attenuation. A single medium PLLC should be used to eliminate computed tomography artifacts during postoperative evaluation of shunt closure.
