Feasibility, reliability, and validity of the Japanese version of the Postoperative Quality of Recovery Scale: a first pilot study.
The Postoperative Quality of Recovery Scale (PQRS) is a multi-domain tracking scale to assess recovery after surgery. The PQRS is used in seven countries and five languages; however, the Japanese version of the PQRS (PQRSj) has not been established. We therefore translated the PQRS into Japanese, and examined the feasibility, reliability and validity of the PQRSj. ⋯ A relationship was shown between cognitive domain and MMSE at baseline (r = 0.65, P < 0.01); however, no relationship was found between the other domains and the MMSE and QoR-40 J. Ceiling effects were observed in 78% of the questions. These results indicate that the PQRSj can be used to assess recovery after surgery, although it may be better to revise some of the questions to improve the validity of the PQRSj.

Randomized Controlled Trial Comparative StudyUltrasound-guided continuous thoracic paravertebral block provides comparable analgesia and fewer episodes of hypotension than continuous epidural block after lung surgery.
Both paravertebral block (PVB) and thoracic epidural block (TEB) are recommended for postoperative pain relief after lung surgery. The addition of fentanyl to the anesthetic solution became popular for TEB because of the stronger effects; however, there have been few comparable trials about the addition of fentanyl to PVB. The purpose of this study was thus to compare postoperative analgesia, side effects, and complications between ultrasound-guided PVB (USG-PVB) and TEB with the addition of fentanyl to ropivacaine after lung surgery. ⋯ USG-PVB achieved similar pain relief and lowered the incidence of hypotension compared with TEB. We conclude that both blocks with the same concentration of ropivacaine and fentanyl can provide adequate postoperative analgesia for VATS.

Despite the many benefits of percutaneous thoracic sympathectomy, it also has serious complications such as pneumothorax. This study was conducted in order to determine the safe percutaneous entering window and angles for the needle during T2 and T3 thoracic sympathectomy avoiding pneumothorax. ⋯ The covariates' relationship and interindividual variability resulting from the mixed-effect analysis enhanced individual prediction for safe widows.

Effects of mechanical ventilation with different tidal volume on oxidative stress and antioxidant in lung.
The aim of this study was to investigate the changes in oxidative stress and antioxidants in lung tissue under different tidal volume ventilation conditions. ⋯ Oxidative stress and antioxidant enzyme levels in the lungs of rats were positively associated with the tidal volumes of mechanical ventilation, suggesting that higher tidal volumes cause more severe oxidative stress and increased antioxidant responses.
