Today surgical site infections (SSIs) remain the second among hospital acquired infections in Europe and the USA. as a pathogen of nosocomial infections occur more frequently in surgical hospitals. The work was aimed to establish the effect of local anesthetics against planktonic forms and biofilm-formation of clinical strains and the relationship between the sensitivity of strains to local anesthetics and antiseptics . The antimicrobial activity of local anesthetics (0.5%, bupivacaine, 2.0% lidocaine, 0.375% ropivacaine) and antiseptics (decamethoxine 0.02%, chlorhexidine 0.05%) against clinical strains of was observed and studied their ability to produce biofilms. The antimicrobial effect of local anesthetics was lower compared to antiseptics, but we observed inhibition of growth and reproduction of in their presence. The ropivacaine solution and the lidocaine solution demonstrated almost the same activity against the studied microorganism isolates. Along with this, bupivacaine solution had the highest activity against the studied microorganisms. The minimal inhibitory concentration of bupivacaine for was 2.2 times lower than the minimal inhibitory concentration of lidocaine and 2.1 times lower than the minimal inhibitory concentration of ropivacaine significantly ( < 0.05). Scientific research on various aspects of the formation of bacterial biofilms is a relevant area that will change approaches to the prophylaxis and treatment of a number of infections, including SSIs.

Objective: To study the effect of transversus abdominis plane (TAP) block under direct vision with acupoint injection on the rapid recovery of patients after laparoscopic cholecystectomy.
Methods: Ninety-three patients undergoing laparoscopic cholecystectomy at Hangzhou Hospital of Traditional Chinese Medicine from January 2023 to December 2023 were selected and divided into control, TAP block under direct vision (TAP-DV), and TAP-DV with acupoint injection (TAP-DVA) groups using a random number table method. Postoperative VAS, Ramsay score, IL-6, CRP, and postoperative rehabilitation indices were compared among the three groups.

Background: Surgical intervention is critical in the treatment of hip developmental dysplasia in children. Perioperative analgesia, usually based on high opioid dosages, is frequently used in these patients. In some circumstances, regional anesthetic procedures such as caudal block and lumbar plexus block have also been used.

Background: In dentistry, local anesthetic is frequently used to manage pain throughout several phases of dental treatments, including tooth extraction. The study aimed to compare the effectiveness of two techniques for controlling pain during mandibular exodontia (tooth extraction), specifically focusing on the pain experienced during injection and extraction of mandibular anterior and premolars teeth. The two techniques being compared are the intraligamentary injection technique (ILI) and the incisive nerve block technique (INB).
