JOURNAL FREE ACCESSThe flow rate of four balloon-driven disposable infusors was examined under various conditions. The flow rate measured under the conditions specified by manufacturers proved to be nearly constant with slight decrease except the periods at the beginning and at the end of the infusion process. A temperature drop from 30 to 25 degrees centigrade caused a decrease of 15% in the DIB Catheter, 18% in the Baxter Infuser, and 19% in the Sure Fuser-A in the flow rate, corresponding mainly to the increase of 12% in the viscosity of the priming solution, and slightly to the increase in the structural resistance of the control unit. On the other hand, the decrease of flow rate in the case of the Vessel Fuser was only 8%, suggesting a decrease in the structural resistance due to an expansion of the snow-crystal-like passage, and also indicating the possibility of temperature compensation. Changes in the flow rate in case of reuse were within a 6% decrease in four models, showing that sufficient accuracy of the flow rate was maintained for reuse.View full abstractDownload PDF (1528K) -

JOURNAL FREE ACCESSThis study was undertaken to investigate the changes in recipient serum electrolytes and arterial blood gas after irradiated blood transfusion. We measured electrolytes and arterial blood gas before and after the transfusion during elective surgery in 55 patients. The mean blood loss was 1, 477g and the mean transfused blood unit of irradiated MAP was 5.9 units. Potassium concentration increased from 3.8 to 4.2 mEq•l-1. A total of 187 units, which had been stored for 12.3±3.5 days after donation and for 5.1±3.8 days after irradiation, was used. There was a significant correlation between the storage period from the day of irradiation and the potassium concentration of the supernatant (r=0.56, p<0.0001). This study recommends that a safe transfusion rate of irradiated blood should be determined because the high potassium concentration of irradiated blood may lead to lethal complications in case of rapid transfusion.View full abstractDownload PDF (583K) -

JOURNAL FREE ACCESSWe analyzed the perioperative complications under spinal anesthesia in 400 eldery patients with hip fracture surgery. Analgesia was fixed of lower than Th10 in all patients.
Hypertension was the highest in preoperative complications. In intra-operative complications, the incidences of hypotention and decrease in percutaneous oxygen saturation (SpO2) were high. Within the 7th post-operative day, some patients had the recurrence or onset of myocardial infarction, cerebral infarction or renal dys-function. Two patients died due to acute myocardial infarction. None of the patients had the typical deep vein thrombosis, but 3 patients had pulmonary infarction.
The results suggest that intraoprative hypotension might cause some post-operative complications under spinal anesthesia in eldery patients undergoing hip fracture surgery, and thus the hemodynamic control would be the most important.View full abstractDownload PDF (548K) -

JOURNAL FREE ACCESSCritical illness polyneuropathy (CIP) is an acute and diffuse motor neuropathy due to axonal dysfunction. We had a case that developed CIP during the treatment of status asthmaticus.
A 71-year-old male patient suffering from asthma was admitted to our intensive care unit for status asthmaticus. After 2 weeks of artificial ventilation, he manifested respiratory muscle weakness and quadriplegia. He was diagnosed with CIP by electrophysiological studies demonstrating axonal neuropathy. It took 3 weeks to wean him from mechanical ventilation and 8 months for him to be able to walk.
This case suggests that we should avoid the predisposing factors which may induce neuropathy or myopathy for critically ill patients. And if they develop paralysis, we have to evaluate not only central nerveous system but also the peripheral one by electrophysiological tests.View full abstractDownload PDF (582K) -

JOURNAL FREE ACCESSI report a case of bilateral pneumothoraces that developed postoperatively in a 66-year-old patient (166cm, 44kg). The patient had no apparent pulmonary or cardiovascular diseases preoperatively. He was scheduled for total gastrectomy under general anesthesia combined with epidural anesthesia. Intraoperatively no pathological episodes occurred. Postoperatively, after extubation, he showed dyspnea with marked inspiratory efforts and cyanosis. He was reintubated immediately and ventilated with 100% oxygen. He was diagnosed with right lung pneumothorax from acoustic sounds and chest X-ray. He received chest drainage and was controlled by spontaneous ventilation. Six hours later the respiratory conditions were impaired again, he was diagnosed with left lung pneumothorax and treated the same way. Twenty hours later the respiratory conditions improved and we finished the respiratory control. We did not know what the causes of the pneumothorax were but it was suggested that operations with upper abdominal surgical maneuvering and mechanical airway pressure alteration at extubation induced airway disorder after operation.View full abstractDownload PDF (990K) -

JOURNAL FREE ACCESSWe report the case of a patient who underwent cardiac surgery in which heparinized blood made from cardiopulmonary bypass residual coagulated after passing through a leukocyte depletion filter, Imugard®III-RC. To investigate the reason for the coagulation, we measured the activated coagulation time (ACT) of heparinized blood before and after filtering, and found that the ACT of blood was significantly lower after the filtering. We reported this fact to the Ministry of Health and Welfare in Japan. We investigated that Imugard®III-RC absorbed heparin molecules from heparinized blood. We added this information in the instructions for use of the device in 1999.View full abstractDownload PDF (586K) -

JOURNAL FREE ACCESSDifficulty in removing catheter is one of the complications of epidural anesthesia, but it is very rare that it is caused by the formation knots in a catheter. A 21-year-old man was prepared for an operation on a femoral fracture. Epidural puncture was performed between L3 and L4. During the catheter insertion there was no sign of neurological incidence and postoperative epidural analgesia was sufficient. The next day, a surgeon tried to extract the catheter but could not. X-ray examination with a contrast showed the tip of the catheter located 3cm under the skin surface, then the catheter was drawn out under local infiltration anesthesia. A knot was found to have formed on the tip of the catheter.
In the case that X-ray examination shows a suspicion of knots forming in a catheter in shallow tissue, considering the possibility of infection and patient anxiety, a surgical procedure should be done as soon as possible.View full abstractDownload PDF (1054K) -
Bladder Injury Identified by AnesthesiologistKeisuke YAMADA, Shun-ichi NITTA, Kazuo HAMATANI2001 Volume 21 Issue 7 Pages 399-402

JOURNAL FREE ACCESSDuring laparoscopic-assisted vaginal hysterectomy (LAVH) on a 47-year-old female patient, an anesthesiologist drew our attention to intraoperative bladder injury when observing carbon dioxide used for pneumoperitoneum leaking through an indwelling bladder catheter into a closed urethral catheterization bag. The surgeons had not recognized the injury. The location of the injury was discovered by injecting indigo carmine via the bladder catheter. The risk of bladder injury is higher in LAVH than in total abdominal hysterectomy. Unrecognized intraoperative bladder injury causes many types of complications. For this reason, gas for pneumoperitoneum leaking through a bladder catheter during LAVH should lead to suspicion of bladder injury, and proper measures should then be taken.View full abstractDownload PDF (388K) -
