Perioperative intravenous lidocaine not only improved gastrointestinal motility but also shortened length of hospital stay significantly. Anti-inflammatory activity modulating the surgery-induced stress response may be one potential mechanism. Systemic lidocaine may thus provide a convenient and inexpensive approach to improve outcome for patients not suitable for epidural anesthesia.

Obtaining blood cultures during antibiotic therapy is associated with a significant loss of pathogen detection. This strongly emphasizes the current recommendation to obtain blood cultures before antibiotic administration in patients with sepsis.

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.

Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a severe adverse effect of ChAdOx1 nCoV-19 COVID-19 vaccine (Vaxzevria) and COVID-19 vaccine Janssen (Ad26.COV2.S), and associated with unusual thrombosis. VITT is caused by anti-platelet factor 4 (PF4) antibodies activating platelets through their FcgRIIa receptors. Antibodies activating platelets through FcgRIIa receptors have also been identified in COVID-19 patients. These findings raise concern that vaccination-induced antibodies against anti-SARS-CoV-2 spike protein cause thrombosis by cross-reacting with PF4. Immunogenic epitopes of PF4 and SARS-CoV-2 spike protein were compared using in-silico prediction tools and 3D-modelling. The SARS-CoV-2 spike protein and PF4 share at least one similar epitope. Reactivity of purified anti-PF4 antibodies from patients with VITT was tested against recombinant SARS-CoV-2 spike protein. However, none of the affinity-purified anti-PF4 antibodies from 14 VITT patients cross-reacted with SARS-CoV-2 spike protein. Sera from 222 PCR-confirmed COVID-19 patients from five European centers were tested by PF4/heparin ELISA and PF4-dependent platelet activation assays. We found anti-PF4 antibodies in 19 of 222 (8.6%) COVID-19 patient sera. However, only four showed weak to moderate platelet activation in the presence of PF4, and none of these patients developed thrombotic complications. Among 10 of 222 (4.5%) COVID-19 patients with thrombosis, none showed PF4-dependent platelet-activating antibodies. In conclusion, antibodies against PF4 induced by vaccination do not cross-react with the SARS-CoV-2 spike protein, indicating that the intended vaccine-induced immune response against SARS-CoV-2 spike protein is not the trigger of VITT. PF4-reactive antibodies found in COVID-19 patients of the present study were not associated with thrombotic complications.

All LA tested inhibited the activation of human NMDA receptors in a concentration dependent fashion. This effect may contribute to reduced hyperalgesia and opiate tolerance observed after systemic administration of LA. The effect is independent of the charge of LA; site of action is intracellular. The mechanism of action may be mediated by inhibition of PKC.
