We report that the transversus abdominis plane block (TAP block) can be performed under ultrasound guidance using not a linear probe but a convex probe in a markedly obese patient undergoing laparoscopy-assisted distal gastrectomy. The TAP block is effective for providing perioperative analgesia. ⋯ We used a low-frequency convex probe for TAP block, which clearly showed the spread of local anesthetics in TAP block in a markedly obese patient. A convex probe is preferable for TAP block in markedly obese patients.

Case Reports
[A case of prolonged neuromuscular blockade possibly related to a high anti-acetylcholine receptor antibody level].
Prolonged neuromuscular blockade is a relatively common complication of general anesthesia. Some previous reports have shown that positive serum anti-acetylcholine receptor antibody (AChR Ab) might contribute to this complication. ⋯ Although this patient had mediastinal tumor diagnosed as thymic carcinoma two years before the operation, preoperative clinical evaluation was negative for myasthenia gravis (MG) and the tumor was in remission at the operation. These observations suggest that preoperative measurement of anti-AChR Ab level might be recommended for patients with mediastinal tumor regardless of symptoms of MG and that neuromuscular blocking agents should be administrated carefully in anti-AChR Ab positive patients under monitoring of the neuromuscular blockade.

Macroglossia is the commonest symptom of Beckwith-Wiedemann syndrome (BWS) and sometimes requires surgical tongue reduction for cosmetic, feeding, drooling and speech problems. ⋯ Airway disorder was not alleviated by tongue reduction surgery or glossopexy.

There are only a few reports on cesarean section in a patient with cervical fracture without spinal cord injury (SCI). Such patients have high risks for deterioration of SCI following general or regional anesthesia. Here, we present a patient with a fracture of C2 vertebra who underwent cesarean section safely under combined spinal and epidural anesthesia(CSEA). ⋯ Pre-viability amniorrhexis was seen at 37 weeks' gestation, and an emergency cesarean section was scheduled under combined epidural and spinal anesthesia (CSEA). Her neck and head were carefully fixed before, during and after surgery in order to prevent subsequent SCI. As a result, cesarean section under CSEA was successfully performed in the patient without any deterioration of the spine and/or SCI.

Several previous reports have established the Pentax Airway Scope (Pentax AWS, S-100, HOYA-PENTAX, Tokyo, Japan) as an efficient tool for endotracheal intubation in adult patients. To date, however, there are no reports on its use with the INTLOCK blade for neonatal and pediatric patients. In this case, we performed tracheal intubation using a Pentax AWS attached to a neonatal-type INTLOCK blade (ITL-N) twice, 1 day and 10 days after birth, in a neonatal patient complicated with Arnold-Chiari malformation. ⋯ We initially attempted tracheal intubation using a Miller's laryngoscope in the first operation and a Macintosh laryngoscope in the second, but we could not achieve tracheal intubation with either of these instruments. Upon switching to a Pentax AWS with an ITL-N, however, we successfully achieved tracheal intubation in both operations. Further research is needed to facilitate the effective use of the Pentax AWS in such cases.
