However, only a thin TE can be used to replace a double-lumen tracheal tube (DLT) with a standard single-lumen tracheal tube (SLT). We successfully replaced a DLT to a SLT by inserting an Aintree Intubation Catheter® (AIC) over a TE in two cases. The AIC (diameter : 19 Fr, overall length : 56 cm) is mainly used for the replacement of various supra- glottic apparatuses using a SLT. In our cases, an AIC with an internal diameter of 4.7 mm was placed over a thin TE with an external diameter of 3.7 mm (11 Fr) to increase the support, and the difference between the SLT with an internal diameter of 7.5 mm and an AIC with an external diameter of 6.3 mm (19 Fr) was decreased, resulting in smooth replacement of the tubes. Even for those cases in which tube replacement might be difficult, acute administration of oxygen could be provided using an AIC with a larger internal lumenthan TE.

Tho- racic truncal blocks include paravertebral, pecs, intercostal, and retrolaminar blocks. Previous studies have demonstrated that paravertebral block provides similar analgesic effects and better hemodynamic stability compared with epidural analgesia. In addition, the results of several studies suggest that paravertebral block may improve long-term outcomes such as pre- vention of chronic pain and decrease in recurrence or metastasis after breast cancer surgery. Pecs blocks are novel ultrasound-guided blocks intended to provide analgesia of the anterior chest wall while avoiding seri- ous complications associated with epidural anesthesia and paravertebral block. The novel ultrasound-guided techniques for intercostal nerve blocks have also been reported. Although some case series support that these pecs and intercostal nerve blocks appear to be safe and effective, prospective randomized studies to confirm their clinical usefulness are lacking. Whether to con- duct these thoracic truncal blocks or not will become a standard clinical practice for thoracic and breast sur- gery is yet to be determined.</p>","PeriodicalId":18254,"journal":{"name":"Masui.
