A 48-year-old man with arteriosclerosis obliterans was scheduled for axillofemoral bypass. He had chronic renal failure and on hemodialysis (HD) for 22 years. On the morning of the day of surgery he received HD and two hours later anesthesia was induced with fentanyl 300 micrograms and midazolam 6 mg, and maintained with fentanyl, nitrous oxide and intermittent isoflurane. The common carotid artery was cannulated to measure arterial blood pressure because arteries in extremities were not available. Internal jugular vein at the other side of the arterial catheterization was cannulated to measure central venous pressure. Crystalloid and blood transfusion was performed to adjust hemodynamics and central venous pressure. Hemodynamics were stable during surgery and no complication occurred regarding the common carotid arterial line. The common carotid artery was useful for blood pressure monitoring in a patient whose extremities were not available. Midazolam and fentanyl could give stable hemodynamics to a patient with arteriosclerosis obliterans and chronic renal failure.

We reported our own experience in four patients with chronic renal failure on maintenance hemodialysis undergoing coronary artery bypass graft surgery (CABGS). A balanced general anesthesia with endotracheal intubation was successfully achieved by using midazolam, atracurium, fentanyl, pentothal, nitrous oxide in oxygen and isoflurane. All patients were hemodialyzed within 24 hours before operation. One patient started peritoneal dialysis 10 hours after surgery. Three other patients were managed by hemodialysis the day after surgery. There was no hospital mortality. Many aspects of management of these patients which differ from those of routine cardiac surgical patients are outlined and discussed.

A national survey on permanent hemodialysis catheters was conducted in 99 hemodialysis centers between january 1998 and january 2000. It was a prospective, national and multicentric study. Data were gathered in 1552 patients (mean age 65 +/- 15 years) with chronic end stage renal failure. A questionnaire was filled out each time a permanent hemodialysis catheter was inserted. Two permanent catheters (72%) were inserted under local anesthesia (92%), using the right internal jugular vein (81%) with a percutaneous technique (96%). The two main indications were: end stage chronic renal failure without creation of a vascular access (52%) and dysfunction of a preexisting vascular access (35%). Patients have been followed a mean time period of 58 days and 179 cases of death have been reported. The median duration of catheters was 500 days. The two main causes of catheter removal were creation of a functional A-V fistula (40%) and death of the patient (28%). The incidence of bacteriemia/septicemia was 0.74 episode/patient/1000 days of follow-up while that of any type of infection was 0.85 episode/patient/1000 days. The risk of infection increased with time especially in type 2 diabetes patients.

We report a case of ventricular chaotic arrhythmia after droperidol administration. A 49-year-old woman with chronic renal failure receiving hemodialysis, was scheduled for total hysterectomy under general anesthesia. General anesthesia was induced with thiopental 200 mg, fentanyl 0.1 mg and vecuronium 5 mg for endotracheal intubation. Anesthesia was maintained with 1% isoflurane and 60% nitrous oxide in oxygen. Droperidol 10 mg was injected for neuroleptanalgesia. After two minutes, ventricular chaotic arrhythmia occurred. Lidocaine 80 mg was injected. General anesthesia was stopped. After two minutes, arrhythmia disappeared. Several reports suggest that patients with preexisting conduction defects or prolonged QTc interval may be at risk to develop ventricular arrhythmias after droperidol administration. Administration of droperidol may have exaggerated prolongation of QTc interval.

Continuous ambulatory peritoneal dialysis are widely used in the management of patients with chronic renal failure. The permanent presence of the catheter into the peritoneal cavity generate a series of specific complications. Two of the most important causes of dysfunctional peritoneal dialysis catheter are obstruction and malposition. Failure to restore the drainage function of the catheter by conservative method should be followed by a surgical procedure: laparoscopic reposition or replacing the catheter. This paper present an original technique which has some major advantages: required local anesthesia; doesn't replace the existing catheter; the dyalysis program could be started very quick after procedure; it is a feasible and reproducible technique.

We present a case report of the anaesthetic management of a 77-year-old man requiring endovascular thoracic stent graft repair. The patient had a history of poorly controlled type II diabetes mellitus and chronic renal failure. Chest X-ray and CT scan showed a right pleural effusion, generalized emphysema and an enlarged thyroid extending into the upper mediastinum, compromising the tracheal lumen. Endovascular stent graft repair was successfully performed under epidural anaesthesia and intravenous sedation.

In this study, controllability, safety, blood cell depletion, and hemolysis of a pulsatile roller pump in high-risk patients was evaluated. Sarns 8000 roller pump (Sams, Terumo CVS, Ann Arbor, MI, USA) with a pulsatile control module was used as arterial pump in a clinical setting. Forty patients undergoing elective open heart surgery with high-risk either having chronically obstructive pulmonary disease or chronic renal failure were randomly included in the study to be operated on using pulsatile perfusion or non-pulsatile perfusion. Blood samples were withdrawn at induction of anesthesia, at the time of aortic clamping and de-clamping and at 1 hour and 24 hours following cessation of the bypass. Hematocrit and plasma free hemoglobin values were measured. We observed that the pulsatile roller pump perfusion and the extracorporeal circuit used in the clinical study is safe in high-risk patients undergoing cardiopulmonary bypass. We did not face any emboli, hemolysis, or technical problems. Pulsatile roller pump perfusion with Sarns 8000 heart-lung machine is a simple and reliable technique and can be easily applied during open heart surgery.

Anesthetic management for nephrectomy using HemoSonic 100, was performed in a patient with chronic renal failure and dilated cardiomyopathy (DCM). Anesthesia was induced and maintained with infusion of propofol and ketamine, and intermittent administration of fentanyl. During the surgery left ventricular ejection time (LVETc) decreased due to active bleeding from the renal artery. LVETc provided useful information for adequate preload and rate of transfusion in this case. Anesthesia and operation were finished successfully with relatively stable circulatory condition. We conclude that HemoSonic 100 is a useful monitor in anesthetic management of a patient with DCM, especially for the assessment of adequate preload.

The purpose of this study was to provide data of propofol-based total intravenous anesthesia (TIVA) for ambulatory surgery in developing a fast-track technique. One hundred and forty-two patients scheduled for elective surgery were studied: mean (SD) age 42.21 (16.23) years, male to female 72:70, mean (SD) body weight 60.75 (11.67) kg and American Society of Anesthesiologists (ASA) physical status I/II/III 66/38/38. Mean (SD) thiopental induction 225 (55.69) mg was maintained with mean (SD) propofol 199.64 (86.26) mg for mean (SD) anesthetic time 29.02 (11.21) minutes. Various narcotics were used: fentanyl 73.48 +/- 24.38 microg for 123 cases, morphine 3.27 +/- 1.10 mg for 10 cases, remifentanil 492 +/- 105.26 microg for 7 cases and pethidine 23.33 +/- 2.88 mg for 2 cases. Midazolam was given 2.70 +/- 1.05 mg. Patients were positioned in supine, lithotomy or lateral decubitus. One-fourth were PS III with a diagnosis of chronic renal failure and renal transplants coming for incision and drainage of perianal abscess. The mean (SD) wake-up time was 36.02 (17.69) seconds. Only one case (chronic renal failure) had severe hypotension after induction. Anesthetic agents and ideas of fast-track anesthesia were discussed.

We describe a patient in whom the bispectral index (BIS) decreased to 0 during surgery. A 42-yr-old man with chronic renal failure was scheduled to undergo construction of an arteriovenous shunt. He had a history of acute cerebral hemorrhage. An intracranial hematoma had been removed a month earlier with almost complete neurological recovery. He had uncontrolled hypertension. His systolic blood pressure was 180 mm Hg before anesthesia induction. Anesthesia was induced with 100 mg of propofol and 3% sevoflurane. After laryngeal mask insertion, anesthesia was maintained with nitrous oxide 60% in oxygen and sevoflurane. BIS decreased to near 0 on 2 occasions: after anesthesia induction and shortly after the start of the surgery. His systolic blood pressure decreased to 110 mm Hg and BIS increased when his blood pressure was increased to 130-140 mm Hg. The decrease in BIS was suspected to be the result of decreased cerebral blood flow. The systolic blood pressure of 110 mm Hg (mean blood pressure, 80 mm Hg) was probably less than the lower limit of autoregulation. Although BIS has some limitations as a cerebral monitor, it was useful for detecting possible cerebral hypoperfusion in this case.
