Randomized Controlled TrialPerioperative inflammatory response in total knee arthroplasty patients: impact of limb preconditioning.
Ischemic preconditioning of tissue that is to undergo procedure-induced underperfusion has been used in a number of surgical settings to reduce the subsequent inflammatory response and its sequelae. The objective of this prospective, randomized study was to evaluate the effect of ischemic preconditioning on the systemic inflammatory response, degree of lung catabolism, and postoperative-pain associated with total knee arthroplasty (TKA). ⋯ Preconditioning of the lower extremity in the setting of TKA under regional anesthesia may have limited value in reducing the systemic inflammatory response and level of lung injury. However, preconditioning may be associated with beneficial effects such as reduction in postoperative pain levels, and thus, further investigations are warranted.

Case ReportsUltrasound-guided continuous phrenic nerve block for persistent hiccups.
Phrenic nerve block can be performed and repeated if necessary for persistent hiccups, when conservative and pharmacological treatment is unsuccessful. We report the first description of an in-plane ultrasound (US)-guided phrenic nerve block (PhNB) with a catheter, after US investigation of the bilateral diaphragm, to treat hiccups while avoiding repeated PhNBs. ⋯ An US-guided in-plane PhNB with catheter is feasible and avoids repeated PhNB when hiccups reoccur. Ultrasound investigation of the bilateral diaphragm should be performed before performing the nerve block.
