Successful anesthetic management of separation surgery for pygopagus conjoined twins: a case report.

Background: Conjoined twins are an extremely rare congenital occurrence, and anesthetic management for surgical separation presents unique challenges for anesthesiologists.

Case Presentation: Five-month-old male pygopagus conjoined twins underwent separation surgery. We performed anesthesia induction in the supine position and surgery in the prone position.

Femoral nerve block with propofol sedation versus general anesthesia in patients with severe cardiac dysfunction undergoing autologous myoblast sheet transplantation.

Purpose: Regional anesthesia is more favorable than general anesthesia in patients with severe comorbidity; however, data on the superiority of peripheral nerve blocks over general anesthesia in patients with severe cardiac dysfunction are lacking. We aimed to demonstrate that peripheral nerve blocks reduce perioperative analgesic requirements and promote faster recovery compared to general anesthesia.

Methods: We retrospectively evaluated intraoperative blood pressure, perioperative medications, and postoperative recovery in patients who underwent skeletal muscle harvesting for autologous myoblast sheet transplantation.

[Comparison of Aortic Valve Replacement Combined with Coronary Artery Bypass Grafting and Transcatheter Aortic Valve Implantation Combined with Off-pump Coronary Artery Bypass Grafting].

Background: The purpose of this study was to compare the perioperative management of aortic valve replacement combined with coronary artery bypass grafting (AVR+CABG) and transcatheter aortic valve implantation combined with off-pump coronary artery bypass grafting (TAVI+OPCAB).

Methods: A retrospective analysis was performed on patients who had undergone either AVR+CABG or TAVI+OPCAB for AS and CAD in Osaka Univer- sity Medical Hospital from January to October, 2014.

Results: AVR+CABG was performed in 11 pa- tients (group A) and TAVI+OPCAB was performed in 4 patients (group T) in this period.

[A case of previously undiagnosed methemoglobinemia exhibiting sustained low SpO2 value at the induction of general anesthesia].

A 70-year-old woman was scheduled to undergo surgery for removal of thyroid tumor under general anesthesia. A routine preoperative evaluation confirmed that the patient was stable with no signs of cyanosis and dyspnea. However, during pre-oxygenation as well as mechanical ventilation with 100% oxygen, she showed sustained low SpO2 values (i.

[7-year survey of anesthesia for cesarean section--comparison of tetracaine and bupivacaine as intrathecal anesthetic agents].

Background: In our institution, spinal anesthesia is the first choice for cesarean section. After the introduction of bupivacaine in 2000 in Japan, the intrathecal anesthetic agent shifted from tetracaine to bupivacaine. We analyzed the anesthesia for cesarean section in recent 7 years and compared the anesthetic quality of tetracaine with that of bupivacaine.
