Meta Analysis Comparative Study
Analgesic efficacy of ultrasound-guided regional anesthesia: a meta-analysis.
To determine if the use of ultrasound guidance (vs non-ultrasound techniques) improves the success rate of nerve blocks. ⋯ Ultrasound-guided peripheral nerve block is associated with an increased overall success rate when compared with nerve stimulation or other methods. Ultrasound-guided techniques also increase the success rate of some specific blocks.

Randomized Controlled Trial Comparative Study
Effects of postoperative background PCA morphine infusion on pain management and related side effects in patients undergoing abdominal hysterectomy.
To examine the effects of background morphine infusion via patient-controlled intravenous analgesia (PCA) device. ⋯ A continuous background morphine infusion of 0.5 mg/hr did not lower pain intensity during movement or at rest, but induced higher pain intensity, higher opioid usage, and more complications such as vomiting, nausea, and dizziness.

Clinical Trial
Morphine and its metabolites after patient-controlled analgesia: considerations for respiratory depression.
To assess concentrations of morphine and its metabolites after patient-controlled analgesia (PCA). ⋯ Patients receiving morphine PCA should be monitored closely from 8 to 24 hours postoperatively. Morphine PCA given with background infusion rates up to 1.0 mg/hr does not offer distinct pharmacokinetic advantages over morphine PCA alone. Morphine PCA with background infusion rate of 2.0 mg/hr is associated with the greatest risk of respiratory depression.

Randomized Controlled Trial
Preoperative lornoxicam for pain prevention after tonsillectomy in adults.
To evaluate the efficacy of preoperative lornoxicam on postoperative pain management following tonsillectomy. ⋯ Preoperative 16 mg lornoxicam was effective for immediate postoperative pain relief after tonsillectomy in adults.
