Randomized Controlled Trial Comparative Study
Comparison of deep or moderate neuromuscular blockade for thoracoscopic lobectomy: a randomized controlled trial.
Laparoscopic surgery typically requires deep neuromuscular blockade (NMB), but whether deep or moderate NMB is superior for thoracoscopic surgery remains controversial. ⋯ Deep NMB can reduce the use of additional muscle relaxant and increase surgeon satisfaction during thoracoscopic lobectomy.

This report describes one case of paravertebral haemorrhage after ultrasound-guided thoracic paravertebral block (TPVB) that may have been attributed to the inadvertent puncture of the posterior intercostal artery (PIA). This complication has never been reported in ultrasound-guided TPVB. Strategies to prevent this potentially serious complication are discussed. ⋯ Ultrasound-guided TPVB still bears the potential risk of inadvertent PIA injury. We recommend colour Doppler imaging to identify PIA prior to the TPVB.

Randomized Controlled Trial Comparative Study
Tramadol for the treatment of catheter-related bladder discomfort: a randomized controlled trial.
Intra-operative urinary catheterization frequently causes postoperative catheter related bladder discomfort (CRBD) during recovery. We conducted this study to evaluate the efficacy of tramadol, which with muscarinic receptor antagonist property, as a treatment for CRBD. ⋯ Tramadol 1.5 mg/kg was more effective than tramadol 1 mg/kg in treating CRBD and reducing postoperative pain, without significant side effects.

Randomized Controlled Trial Comparative Study
Effects of patient-controlled analgesia with hydromorphone or sufentanil on postoperative pulmonary complications in patients undergoing thoracic surgery: a quasi-experimental study.
To compare the analgesic effects of patient-controlled intravenous analgesia (PCA) with hydromorphone and sufentanil after thoracic surgery on postoperative pulmonary complications (PPCs). ⋯ Compared with sufentanil, hydromorphone may provide better postoperative analgesic effect with less pulmonary complications for patients undergoing thoracic surgery, and it may accelerate patients' rehabilitation.

Randomized Controlled Trial Comparative Study
Ultrasound-guided continuous femoral nerve block: a randomized trial on the influence of femoral nerve catheter orifice configuration (six-hole versus end-hole) on post-operative analgesia after total knee arthroplasty.
Multiorifice catheters have been shown to provide superior analgesia and significantly reduce local anesthetic consumption compared with end-hole catheters in epidural studies. This prospective, blinded, randomized study tested the hypothesis that, in continuous femoral nerve block (CFNB) under ultrasound guidance, multiorifice catheter would reduce local anesthetic consumption at 24 h compared with end-hole catheter. ⋯ In this superiority trial, catheter orifice configuration did not influence the effectiveness of CFNB in this setting: quality of analgesia was similar, with no reduction in either local anesthetic or morphine consumption, and equivalent postoperative quadriceps weakness.
