Clinical Trial
[Postoperative Analgesia in Peritonectomy for Patients with Peritoneal Surface Malignancy].
We investigated the efficacy of postoperative analgesia in peritonectomy for patients with peritoneal surface malignancy, by comparing peripheral nerve block (PNB) with intravenous patient controlled analgesia (iv-PCA) group to patient controlled epidural analgesia (PCEA) group. ⋯ PNB+iv-PCA decreased the rate of administration of flurbiprofen as compared to PCEA for postoperative pain after peritonectomy.

We describe a case of anaphylaxis that occurred in a 33-year-old gravida 1, para 1 term woman scheduled for cesarean delivery for breech presentation. Her past history was unremarkable except for orciprenaline allergy. Spinal anesthesia was performed at L3-4 using 2.5 ml of 0.5% hyperbaric bupivacaine and 0.1 mg morphine. ⋯ The baby's electroencephalogram, however, demonstrated a pattern consistent with mild hypoxic-ischemic encephalopathy. Lymphocyte stimulation test revealed that she was allergic to bupivacaine. If maternal hypotension persists, i.m. or i.v. adrenaline should be administered immediately because maternal hypotension and hypoxemia may cause significant fetal morbidity and mortality and prompt cesarean section should be considered.

The bifurcation into tibial nerve and common peroneal nerve is generally targeted for sciatic nerve block at popliteal approach. However, it is sometimes difficult to determine the exact bifurcation point in clinical situation. The mean distance between the popliteal fossa and division of sciatic nerve (DPDSN) was reported approximately 6 cm ± 2.5 cm in Caucasian cadaver study. We also studied DPDSN in Japanese cadaver to find ethnic difference. ⋯ DPDSN of Japanese cadaver is shorter than the previously reported data in Caucasian cadaver. Since the DPDSN has inter-individual and intra-individual differences, we should estimate the DPDSN carefully in each leg using ultrasonography and nerve stimulator.

We evaluated whether using thromboelastometry and tranexamic acid influenced blood loss and transfusion requirements in cardiac surgery requiring cardiopulmonary bypass. ⋯ The use of ROTEM and tranexamic acid can potentially reduce blood loss and transfusion requirements in cardiac surgery.

Using an algorithm by which the effect-site concentration of propofol (esTEC) necessary for BIS level set from information input from BIS monitor and TCI pump is estimated, the effect of remifentanil on esTEC was investigated. ⋯ A mutual interaction was observed between propofol esTEC and remifetanil. For anesthetic management with less variation in BIS levels, it was considered that 10 ng x ml(-1) or higher of the effect-site concentration of remifetanil would be necessary.
