We used a new method for central venous (CV) access via the distal femoral vein using ultrasound guidance in two cases. In the first case, because of multiple catheter punctures for hemodialysis previously, femoral catheter placement was impossible using a standard landmark technique. In the second case of laryngoplasty, it was also impossible to place a CV catheter at usual groin sites because of extensive mycosis. ⋯ However, the femoral CV catheters at inguinal site has been associated with higher incidence of catheter infection than the subclavian or internal jugular vein. These methods have a potential for decrease in catheter infection rate. These two case reports suggest that the CV catheterization at distal femoral site by ultrasound-guidance is useful as a new method of CV access.

Case Reports
[Evaluation of epidural blood patch in the treatment of two cases of spontaneous intracranial hypotension].
We evaluated the effect of epidural blood patch (EBP) in the treatment of two cases of spontaneous intracranial hypotension (SIH). Both case 1 (53-year old female) and case 2 (44-year old female) had severe postural headache and showed meningeal thickening by cranial MRI, and were diagnosed as SIH. Case 1: Although her intracranial pressure remained within normal ranges, an extradural leakage was shown in the middle thoracic region on isotope cisternography using indium-111 labeled DTPA. ⋯ Case 2: Her intracranial pressure was low (0 mmH2O on supine position), but, isotope cisternography using DTPA showed only the early appearance of isotope in the bladder but failed to disclose the site of the CSF leak. Epidural blood patch with 30 ml of autologous blood was performed at Th 12-L 1 level which only resulted in severe backache without clinical improvement. In conclusion, we could not find the effectiveness of EBP on the two cases of SIH, although there are many reports on its efficacy.

Case Reports
[Epidural anesthesia for cesarean section in a twin pregnant patient with severe aortic stenosis].
A 35-year-old twin primigravida with aortic stenosis underwent cesarean section under epidural anesthesia. She had her ventricular septal defect repaired at 3 years of age. Preoperative ultrasonic study revealed severe aortic stenosis in which valve area was 0.77 cm2 and pressure gradient between the left ventricle and the aorta was 80 mmHg. ⋯ Otherwise, peripartal hemodynamics was stable, and she was transferred to the intensive care unit (ICU). Postoperative pain was controlled with epidural infusion of fentanyl. She did not complain of chest pain perioperatively and was discharged from the ICU next day.

We investigated the effects of the presence or absence of N2O in propofol anesthesia using a laryngeal mask on the incidence of postoperative sore throat. In the N2O-combined anesthesia group (n = 25), score 0 (no sore throat) was observed in 11 patients; score 1 (slight pain and discomfort that improved on the next day of operation) in 9; and score 2 (persistent pain on the next day) in 5. In the non-N2O-combined anesthesia group (n = 25), score 0 was observed in 21 patients, score 1 in 3; and score 2 in 1, showing a significantly lower incidence of sore throat and milder sore throat than in the N2O-combined anesthesia group. These results suggest that propofol anesthesia using a laryngeal mask not combined with N2O reduces the incidence of postoperative sore throat.
