AbstractLidocaine is commonly used for regional anesthesia and nerve blocks. However, recent clinical studies demonstrated that intravenous perioperative administration of lidocaine can lead to better postoperative analgesia, reduced opioid consumption and improved intestinal motility. It can therefore be used as an alternative when epidural analgesia is contraindicated, not possible or not feasible. Apart from the sodium channel blocking effects relevant for regional anesthesia, lidocaine also has anti-inflammatory properties. Lidocaine can obviously inhibit the priming of resting neutrophilic granulocytes, which, simplified, may reduce the liberation of superoxide anions, a common pathway of inflammation after multiple forms of tissue trauma. At the authors' institutions intravenous lidocaine is primarily used for postoperative pain relief following abdominal surgery and is given as a bolus dose of 1.5-2.0 mg/kg body weight (BW) injected over 5 min followed by an infusion of 1.5 mg/kg BW/h intraoperatively and 1.33 mg/kg BW/h postoperatively in the recovery room or in the intensive care unit (ICU). The lidocaine infusion is stopped in the recovery room 30 min before discharge or in the ICU at the latest after 24 h. Lidocaine is not used on normal wards. This overview summarizes the current evidence for the intravenous administration of lidocaine for patients undergoing different types of surgery and gives practical advice for its use.
