Lumbar spine superior-level facet joint violations: percutaneous versus open pedicle screw insertion using intraoperative 3-dimensional computer-assisted navigation.
Percutaneous pedicle screw use has a high rate of cranial facet joint violations (FVs) because of the facet joint being indirectly visualized. Computer-assisted navigation shows the anatomic structures clearly, and may help to lower the rate of FVs during pedicle screw insertion. This study used computed tomography (CT) to evaluate and compare the incidence of FVs between percutaneous and open surgeries employing computer-assisted navigation for the implantation of pedicle screw instrumentation during lumbar fusions. ⋯ With computer-assisted navigation, the placement of top-loading percutaneous screws carries a lower risk of adjacent-FVs than does the open technique; when FVs occur, they tend to be less serious. Performing a single-level open lumbar fusion, or the fusion of the L5-S1 segment, requires caution to avoid cranial adjacent FVs.

Randomized Controlled TrialCombined incisional ropivacaine infiltration and pulmonary recruitment manoeuvre for postoperative pain relief after diagnostic hysteroscopy and laparoscopy.
Preoperative incisional local anaesthesia with ropivacaine is a common method of providing post-laparoscopy pain relief. The pulmonary recruitment manoeuvre also provides pain relief, but the combined effect of these two methods on pain following laparoscopic procedures has not been reported. We investigated the efficacy of combining local anaesthetic infiltration of ropivacaine with pulmonary recruitment manoeuvre on postoperative pain following diagnostic hysteroscopy and laparoscopy. ⋯ Ropivacaine with pulmonary recruitment manoeuvre provided simple and effective pain relief after diagnostic hysteroscopy and laparoscopy.

Randomized Controlled TrialUltrasound-guided continuous adductor canal block for analgesia after total knee replacement.
There are several methods for postoperative analgesia for knee surgery. The commonly utilized method is multimodal analgesia based on continuous femoral nerve block. The aim of this study was to investigate the application of continuous adductor canal block for analgesia after total knee replacement and compare this method with continuous femoral nerve block. ⋯ Continuous adductor canal block with 0.2% ropivacaine could be used effectively for analgesia after total knee replacement. Compared with continuous femoral nerve block, this analgesic method has similar analgesic effects and is associated with less weakness of quadriceps muscle.

Effective background infusion rate of ropivacaine 0.2% for patient-controlled interscalene brachial plexus analgesia after rotator cuff repair surgery.
Continuous interscalene nerve block (CISB) is considered to be the most effective method for postoperative analgesia after shoulder surgery with prolonged severe pain. This study was performed to evaluate the minimum effective background infusion rate and the effective background infusion rate of ropivacaine 0.2% for CISB after arthroscopic rotator cuff repair surgery in 95% of patients. ⋯ The effective background rate for patient-controlled interscalene brachial plexus analgesia after shoulder surgery in 50% and 95% of the patients was 2.8 and 4.4 ml/h, respectively.

Controlled Clinical TrialImpairment of recovery of muscle function by residual rocuronium after re-transfusion of intraoperative salvaged blood.
Recurarization has previously been described in the context of acute normovolemic hemodilution. The aim of this study was to investigate the impairment of recovery of neuromuscular function after re-transfusion of intraoperative salvaged blood in patients treated with rocuronium. ⋯ In patients who had received a rocuronium infusion during anesthesia, re-transfusion of salvaged blood significantly impaired recovery of neuromuscular function recovery in the PACU, but without significant impairment of respiratory function.
