　View Summary

A 68·year-old man with reactive thrombocytemia (platelet count:97.2x104·mm-3) underwent liver subsegmentectomy for hepatocellular carcinoma. Thoracic epidural combined with general anesthesia was carried out for the surgery. Platelet aggregability was monitored during the operation. At the beginning of the operation, platelet aggregability to aggregating factor ADP showed an abnormal pattern without dose dependency. In spite of continuous administration of gabexate mesilate for inhibition of thrombosis, the patient developed hypercapnia with low end tidal CO2 pressure (PETco2) and hypoxia, suggesting pulmonary embolism. PETco2 and Spo2 recovered soon after heparin administration. The patient recoverd without any neurologic complications. This case demonstrated that hyperaggregability is possible in patients with thrombocytemia and suggests that monitoring of platelet function in patients with thrombocytemia is difficult.

　View Summary

Purpose: To examine the delivery rates of four disposable, non-electric infusion pumps during hypobaric conditions. Methods: Four models categorized by three different driving forces, one vacuum unit (Coopdech Syringector), one spring unit (Linear-fuser), and two elastomeric balloon-powered units (Multirate Infuser LV and Large DIB), were tested. Each infusion pump was placed in an airtight container, and the pressure in the container was decreased to 1,000, 900, and 800 hPa. The catheter tip of each pump was exposed either to atmospheric pressure (1,000 hPa) or to similar hypobaric conditions (800-1,000 hPa). Results: Under normal atmospheric pressure, each pump showed an accurate delivery rate in the range of -2% to +8% of the set infusion rate (4.0-5.0 mL.hr(-1)). With the catheter tip exposed to atmospheric pressure, the infusion rate of each pump was reduced from 35% in the case of the Large DIB to 64% in the case of the Coopdech Syringector, depending on the magnitude of change in hypobaric pressure. When the pressure acting on the catheter tip was reduced to a level similar to that exerted on the pump body, infusion rate was reduced (by 19%-27%) in all three types of pump, and the Large DIB showed no significant difference in performance compared to normal atmospheric pressure. Conclusion: The infusion rates of disposable infusion pumps are reduced under hypobaric conditions. Even though we still do not know how the epidural pressure changes under hypobaric conditions, clinicians should be aware that the infusion rate of disposable infusion pumps is decreased under hypobaric conditions.
