Randomized Controlled Trial Comparative StudyAnalgesic efficacy and outcome of transversus-abdominis plane block versus low thoracic-epidural analgesia after laparotomy in ischemic heart disease patients.
Tranversus-abdominis plane (TAP) block is a novel technique alternative to central neural blockade in providing analgesia to the anterior abdominal wall. As such, we compared the analgesic efficacy of TAP block with low thoracic-epidural analgesia (TEA) in ischemic heart disease patients after abdominal laparotomy. ⋯ Low TEA reduced morphine consumption and provided a higher analgesic efficacy compared with TAP block after laparotomy in ischemic heart disease patients.

Case ReportsFatal pulmonary embolism following spinal surgery in a patient with permanent inferior vena cava filter placement.
It has been proven that the use of an inferior vena cava filter (IVCF) is effective in decreasing the incidence of pulmonary embolism (PE) in high-risk spinal surgery patients. A case of fatal PE after spinal surgery in a 78-year-old woman who had a history of pulmonary hypertension due to peripheral PE treated with a permanent IVCF and anticoagulant therapy for 3 years is reported. The patient had experienced an episode of recurrent PE during the withdrawal of anticoagulants, but she had uneventfully undergone two orthopedic surgeries with a preoperative unfractionated heparin infusion instead of oral warfarin. ⋯ The patient died 2 h and 30 min after onset. Acute PE probably occurred because of a massive thrombus above the IVCF. This case suggests that the efficacy of long- term use of a permanent IVCF is limited in cases when anticoagulants must be withdrawn, such as for orthopedic surgery.

Case ReportsPostsurgical coagulopathy in a hemophilia A patient with inhibitors: efficacy of recombinant factor VIIa.
Perioperative hemostatic management in patients with hemophilia A who develop the coagulation factor VIII (FVIII) inhibitor is challenging, because exogenous FVIII is neutralized, which boosts the inhibitor to provoke postoperative coagulopathy. Recombinant activated factor VII (rFVIIa) has become available for this type of patient, although FVIII is sometimes required. We treated a 56-year-old male patient with hemophilia A with FVIII inhibitor scheduled for total hip arthroplasty (THA) and total knee arthroplasty (TKA). ⋯ The amount of bleeding during TKA was 1,340 ml, while the level of the inhibitor increased to a greater level than that after THA, provoking uncontrollable bleeding. For anesthetic management in hemophilia A patients with FVIII inhibitor, anesthesiologists must pay attention to postoperative coagulopathy, and every effort should be used to minimize exposure to FVIII. Furthermore, when rFVIIa is ineffective, postponement of surgery until rFVIIa regains its efficacy may be beneficial as compared to an operation with FVIII.

Case ReportsDeep hypothermic circulatory arrest for hemiarch replacement in a pediatric patient with moyamoya disease.
Moyamoya disease is a chronic cerebrovascular occlusive disease, occurring predominantly in young populations, that causes cerebral ischemia and hemorrhage. Patients with moyamoya disease are at high risk of neurological complications during cardiac surgery because of perioperative hemodynamic changes. ⋯ We report a successful case of a pediatric patient with moyamoya disease who underwent deep hypothermic circulatory arrest (18 °C) for hemiarch replacement without neurological complications. Deep hypothermia may be an alternative technique for achieving cerebral protection in the context of moyamoya disease.

Where is the apex of the sacral hiatus for caudal epidural block in the pediatric population? A radio-anatomic study.
Caudal epidural block (CEB), administered through the sacral hiatus, is a regional anesthetic technique commonly used in children. To facilitate and optimize pediatric CEB, morphometric data that may be important for the sacral hiatus have been obtained using multidetector computed tomography (MDCT). ⋯ Dural puncture is inevitable for CEB applied at the S2 level. Consequently, CEB should be applied below this level (range, 1.36-2.17 cm) from the midpoint of the interspinous distance between the PSIS (at the same level with S2) in children aged 1-9 years.
