Transversus Abdominis Plane Block in Colorectal Surgery: A Meta-Analysis.

Front Med (Lausanne) 2021 23;8:802039. Epub 2022 Feb 23.

Department of Mechanical and Aerospace Engineering, School of Engineering and Digital Sciences, Nazarbayev University, Nur-Sultan, Kazakhstan.

Acute postoperative pain is one of the most common concerns during the early postoperative period in colorectal surgery. Opioids still represent the cornerstone of postoperative pain management, yet they often result in significant side effects such as nausea and/or vomiting, sedation, urinary retention, delayed recovery of colonic motility, respiratory depression, and postoperative ileus. Transversus abdominis plane (TAP) block has been widely used for postoperative analgesia in various abdominal surgeries. Read More

Duration of skin desensitisation following palmar digital nerve blocks with lidocaine, bupivacaine, mepivacaine and prilocaine.

Aust Vet J 2021 Dec 26;99(12):541-546. Epub 2021 Sep 26.

Small Animal Surgery Department, College of Veterinary Medicine, Murdoch University, Perth, Western Australia, Australia.

Objective comparative evidence of the time to onset and duration of effect provided by local anaesthetic (LA) agents for perineural blocks in the horse is lacking. Clear knowledge of these properties is required to guide clinically appropriate agent selection and aid interpretation of response to diagnostic blocks for lameness examinations. An interventional study, with complete, randomised crossover design was used to compare time to onset and duration of skin desensitisation provided by four LA agents applied to palmar digital nerve blocks in 12 horses.
