In vitro performance evaluation of two rapid fluid infusion devices [Meeting Abstract]

Capan L.M.; Chakiryan N.; Miller S.M.; O'Neill D.K.; Jacobson J.; Martinez E.A.
Introduction : Rapid infusion devices are becoming increasingly popular for the administration of warm fluids and blood in hypovolemic patients. A recently developed system, Thermacor 1200 (Smisson-Cartledge Biomedical LLC, Macon, GA), consists of a central device to which a disposable cartridge of fluid lines attaches. Performance characteristics of this device have yet to be evaluated. We compared the Thermacor 1200 with a currently utilized infusion device, FMS 2000 (Belmont Instrument Corp., Billerica, MA), to evaluate maximum flow rates, accuracy of actual versus set flow rates, fluid warming capabilities, and air bubble elimination. Methods : A ThermaCor 1200 and an FMS 2000, owned by our institution, were evaluated in vitro after being tested for proper functioning. FMS 2000 was tested with the packaged 4.5ft patient line, and Thermacor 1200 with packaged 3ft (TC3) and 6ft (TC6) patient lines. Maximum flow rates of lactated Ringer's (LR) and expired packed red blood cells (PRBCs) were measured with 22, 20, 18, 16, 14 and 8.5F gauge catheters, using a graduated cylinder and stopwatch. Flow rate accuracy was determined by comparing the actual versus displayed flow rates, for LR and PRBCs. Temperature was measured, at various flow rates, with an electronic probe (Wavetek 23XT, San Diego, CA) positioned 3cm from the distal port of the outflow tubing, for LR and PRBCs. Air elimination capability was determined, for LR only, by infusing fluid into an inverted 20mL syringe submerged in a bucket of water, and measuring the resulting air trapped in the syringe. All measurements were repeated six times. Data were analyzed using one-factor ANOVA, and the Tukey multiple comparisons method. Statistical significance was defined as p<0.05. Results : Maximum flow rates were higher with TC3 and TC6 than with FMS 2000 in most instances, especially when using larger catheter bores (Table 1). Flow rates were more accurate with TC3 and TC6 than with FMS 2000 for LR (1.4, 1.6, and 3.5% variance from target rate, respectively; p<.001) and for PRBCs (2.1, 2.6, and 5.9% variance from target rate, respectively; p<.001). Temperatures of delivered fluid were higher with TC3 and TC6 as compared to the FMS 2000 for LR (38.0, 37.8, and 36.8degreeC. respectively; p<.001) and PRBCs (38.2, 38.1, and 37.2degreeC, respectively; p<.001). Air was not detected in fluid infused from either device. Discussion : In this experiment, the performance of the Thermacor 1200, at both lengths of patient line, was superior to that of the FMS 2000 in that it infused LR and PRBCs at higher and more accurate flow rates, at higher temperatures.

Sonographically guided infraclavicular brachial plexus block in adults: a retrospective analysis of 1146 cases

Sandhu, Navparkash S; Manne, Joseph S; Medabalmi, Praveen K; Capan, Levon M
OBJECTIVE: The aim of this study was to analyze our experience in 1146 cases of sonographically guided infraclavicular brachial plexus block (ICBPB) performed over 32 months. METHODS: Anesthetic records of 1146 cases of sonographically guided ICBPB performed by our staff were studied retrospectively with the use of a database created by an automated anesthesia record-keeping system. The rates of successful blocks, failed blocks necessitating conversion to general anesthesia or requiring supplementation with local anesthetics, those requiring larger-than-usual doses of sedation, and complications were determined. Analysis included an attempt to determine the possible causes of inadequate blocks and complications. RESULTS: In 1138 patients (99.3%), the block was successful. Six patients had incomplete blocks requiring general anesthesia, and another 2 patients needed local anesthetic supplementation by the surgeons. Ninety-seven percent of the blocks were performed by residents directly supervised by an attending anesthesiologist who held the ultrasound probe. The mean age+/-SD of the patients was 39+/-15 years; the mean duration of surgery was 165+/-114 minutes; and the male-female ratio was 4:1. More than 50% of patients were obese. There were no reported cases of nerve injury, pneumothorax, or local anesthetic toxicity. Arterial punctures occurred in 8 (0.7%) patients, but all were inconsequential. CONCLUSIONS: The data from this retrospective study suggest that sonographic guidance provides a high success rate (99.3%) and improved safety for ICBPB. The increased operator team experience virtually eliminates failure and complications

Feasibility of an infraclavicular block with a reduced volume of lidocaine with sonographic guidance

Sandhu, Navparkash S; Bahniwal, Charanjeet S; Capan, Levon M
OBJECTIVE: A successful brachial plexus block requires a large volume of a local anesthetic. Sonography allows reliable deposition of the anesthetic around the cords of the brachial plexus, potentially lowering the anesthetic requirement. METHODS: Fifteen sonographically guided infraclavicular blocks were performed in 14 patients with 2% carbonated lidocaine with epinephrine through a 17-gauge Tuohy needle. The amount of lidocaine injected at several points around each cord was based on satisfactory spread observed sonographically. A 19-gauge catheter was then placed with its tip between the posterior cord and axillary artery, and tip position was confirmed by observing the spread of 1 to 2 mL of injected air. Lidocaine was injected through the catheter if necessary to prolong the blocks. RESULTS: Surgery was performed in all patients without general anesthesia, rescue blocks, or infiltration. A heroin user was given an additional 50 microg of fentanyl before the block. One patient required 5 mL of lidocaine through the catheter for an incomplete radial nerve block 5 minutes after initial injection. Seven patients received additional midazolam (mean, 2.5 mg) for alleviation of anxiety despite excellent blocks. The mean +/- SD volume of lidocaine for the initial block was 16.1 +/- 1.9 mL (4.2 +/- 0.9 mg/kg). In 4 patients, additional lidocaine 1 hour after an initial successful block increased the total volume to 19.5 +/- 7.1 mL (5 +/- 1.9 mg/kg). The mean times to perform the block, onset of the block, and achieving surgical anesthesia and the duration of surgery were 10.8 +/- 3.3, 2 +/- 1.3, 5.9 +/- 2.6, and 92.7 +/- 54.4 minutes, respectively. CONCLUSIONS: A successful infraclavicular block in adults with 14 mL of lidocaine is feasible with the use of sonography. The reduced volume does not seem to affect the onset but shortens the duration of the block

Deep venous thrombosis revealed during ultrasound-guided femoral nerve block [Case Report]

Sutin, K M; Schneider, C; Sandhu, N S; Capan, L M
Ultrasound imaging used to facilitate performance of a femoral nerve block also affords imaging of adjacent anatomical structures. Following a fracture of the femur, an ultrasound guided femoral nerve block (UGFNB) was performed to provide analgesia; this led to the incidental finding of a previously undiagnosed femoral vein thrombosis (DVT), resulting in a change in patient management before surgery. An inferior vena cava (IVC) filter was placed before intramedullary nailing of the fracture
