Influence of a Tourniquet on Opioid Consumption After Local Infiltration Analgesia for Total Knee Arthroplasty.
Local infiltration analgesia (LIA) with ropivacaine is increasingly used to provide postoperative analgesia after total knee arthroplasty (TKA). TKA may be performed with or without the use of a tourniquet. The absence of local blood flow when infiltrating local anaesthesia below an inflated tourniquet may affect the rate of systemic absorption, and this may have an effect on the duration and intensity of analgesia as compared with LIA without the use of a tourniquet. The aim of the present study was to investigate the influence of tourniquet use during surgery on the time to first request (TTFR) of opioids and opioid consumption. ⋯ There was no difference in the time to first opioid consumption, suggesting that the presence of an inflated tourniquet during local anaesthetic injection does not alter systemic absorption sufficiently to affect the duration of analgesia. However, the use of a tourniquet was associated with a higher opioid consumption, which is most likely caused by pain resulting from the tourniquet itself.

Comparative Analysis of Balloon Compression and Radiofrequency Ablation in Idiopathic Trigeminal Neuralgia: A Retrospective Study with a 24-Month Follow-up.
Trigeminal neuralgia (TN) is a common cause of facial pain, with a prevalence of 40 per million. This paper is a retrospective 24-month follow-up study of 20 patients with idiopathic drug-resistant TN who underwent balloon compression (BC) or radiofrequency ablation (RFA). ⋯ BC and RFA are effective modalities of treatment for idiopathic TN with comparable results. In TN involving multiple divisions, BC may be more convenient.
