Efficacy and safety of intravenous lidocaine for postoperative analgesia and recovery after surgery: a systematic review with trial sequential analysis

Abstract: There is limited evidence suggesting that i.v. lidocaine may be a useful adjuvant during general anaesthesia because of its beneficial impact on several outcomes after surgery.

“…Previous studies suggested that IV lidocaine contributed to pain relief in patients after laparoscopic abdominal surgery at 24 hours, but the intervention group did not benefit from lidocaine administration compared with the placebo group at 48 hours. 29,30 A recent study, similar to ours, found that the lidocaine group had lower pain scores on movement, but there was no difference in the two groups at rest within 24 hours. 14 There are several reasons that could explain the lack of efficacy in decreasing pain scores at rest.…”

“…Pain relieving actions of blockade of nociceptive input arising from the periphery is clinically validated (e.g., local anesthetics), however this is not always possible in patients [96]. Additionally, inhibition of the physiological function of pain can be dangerous and can lead to bodily harm as seen in patients with congenital insensitivity to pain [21; 58].…”

“…However, the addition of postoperative low-dose ketamine infusions in sub-anesthetic doses to parenteral hydromorphone has not been demonstrated to decrease postoperative opioid use (7476). Other opioid-sparing intraoperative and postoperative strategies such as lidocaine and dexmedetomidine infusions are also potential options, but have not been rigorously studied in trials focusing on chronic opioid users (77)(78)(79). A discussion with the anesthesiologist may allow for optimal selection of adjunctive intraoperative agents, to improve postoperative pain control.…”
