We experienced a difficult orotracheal intubation in a patient with Cornelia de Lange syndrome. The patient was an eight-year-old girl with Cornelia de Lange syndrome, cleft palate and tetralogy of Fallot who underwent emergency hemicolectomy for strangulation ileus. ⋯ The patient's condition was stable during both intubation and operation. In conclusion, we must be careful on endotracheal intubation of patients with congenital anomalies.

For two cases of cardiac tamponade following cardiac surgery, the approaches for pericardial drainage were determined by the transesophageal echocardiography under general anesthesia. In most cases of cardiac tamponade after cardiac surgery the pericardial effusion is regional and localized due to adhesions of pericardium. Therefore subxiphoid incision approach of pericardial drainage cannot often be accomplished. In these cases transesophageal echocardiography can image the presence, location and size of the pericardial effusion and is an available method to determine the approach of pericardial drainage.

A new programmable syringe infusion pump, Auto Syringe Model AS 40 A, was evaluated for infusion of muscle relaxants, vasodilators and opioids in 4 surgical patients. Every drug mentioned above was easily adjusted according to surgical requirement in these patients. ⋯ Its major advantages lie in the mechanisms for delivery of a bolus dose and automated delivery of intermittent doses, automatic rate calculation, and the applicability to various sizes of syringes. Auto Syringe Model AS40A was found to be very useful for intravenous infusion of drugs.

We anesthetized a patient who received an emergency internal carotid artery ligation. Regional cerebral oxygen saturation (rSO2) was measured with near infrared spectroscopy (NIRS) during the whole anesthetic course. The sensor was placed on the left forehead of the patient. ⋯ However, cerebral infarction in the middle cerebral artery region, the onset of which remained unclear, was revealed postoperatively, regardless of a stable rSO2 during the operation. This monitor may provide useful information regarding the cerebral circulation during the operation in such a case as the present one, but this monitor reflects only the oxygenation of the region on which the sensor was placed. Thus, we should keep in mind the limitation in detecting cerebral dysfunction using NIRS.

According to the roentgenographically confirmed intervertebral space at which an epidural catheter was placed, 241 patients who underwent abdominal or orthopedic hip surgery were allocated into 3 groups. Groups A, B, and C received epidural catheterization at Th7-10, Th10-L1, and L1-4, respectively. In each group, we examined the intervertebral space, which the anesthesiologist who had placed epidural catheter had determined, and the one which had been confirmed roentgenographically. ⋯ In contrast, when we counted down from the cervical prominent vertebra, a landmark of C7, the agreement was better in group A (55%) than in group C (33%). In the postoperative period, catheters came out more frequently in groups A and B than in group C, resulting from the early ambulation in abdominal surgery groups. There results suggest that, to place the epidural catheter more properly, (1) we should start to count from the landmark which is close to the puncture point and (2) we should keep it in mind that catheters come out accidently in patients who are encouraged to ambulate in the early postoperative period.
