Background And Objectives: Review of various techniques for digital blocks with local anesthetic, with or without epinephrine.
Contents: Description of various procedures and comparison of results reported in the literature, mainly on latency and quality of anesthesia, details on vasoconstrictor effect of epinephrine, intraoperative bleeding, necessity of tourniquet use, duration of anesthesia and postoperative analgesia, blood flow and digital SpO2 behavior, local and systemic complications, and also approaches and drugs to be used in certain situations of ischemia.
Conclusions: The advantages of adding epinephrine to the anesthetic solution are minor when compared to the risks of the procedure, and it seems dangerous to use a vasoconstrictor in the fingers, unless the safety of the technique and the possibility of discarding the tourniquet are definitely proven.

Shanxi Provincial Integrated TCM and WM Hospital, Taiyuan, China.
Rationale: Local anesthesia is a widely used technique for emergency wound closure, with lidocaine among the most commonly employed local anesthetics. Allergic reactions to lidocaine are rare, with anaphylaxis being even more uncommon.
Patient Concerns And Diagnosis: This report describes a 72-year-old male patient who presented with a right foot injury and underwent wound suturing under lidocaine local anesthesia.
Is WALANT Really Necessary in Outpatient Surgery?
J Pers Med
December 2024
Department of Orthopaedics and Traumatology, Universita' Cattolica del Sacro Cuore, Largo Agostino Gemelli 8, 00168 Rome, Italy.
: The Wide Awake Local Anesthesia No Tourniquet (WALANT) technique has revolutionized outpatient hand surgery, enabling procedures such as carpal tunnel release and trigger finger release without a tourniquet. Its benefits include patient cooperation during surgery, especially for tendon repairs. However, WALANT has limitations, including a steep learning curve, longer operative preparation time, and risks such as digital ischemia and adrenaline-induced cardiac ischemia.

Universidade do Extremo Sul Catarinense, Criciúma, Santa Catarina, Brazil.
Background: The role of left ventricular global longitudinal strain (LVGLS) in coronary artery bypass grafting (CABG) and outcomes such as low cardiac output syndrome (LCOS) is not well established. The authors investigated the relationship between LVGLS before and after induction of anesthesia, their differences, and their relationship with LCOS and other outcomes.
Methodology: A prospective observational study was conducted in a public/private hospital with 50 adult patients scheduled for on-pump CABG with normal left ventricular ejection fraction (LVEF).
Continuous local infiltration analgesia is equal to femoral and sciatic nerve block for total knee arthroplasty.

Department of Anaesthesia, Main-Kinzig-Kliniken, Herzbachweg 14, 63571, Gelnhausen, Germany.
Background: Total knee arthroplasty (TKA) is associated with moderate to severe postoperative pain. Pain control is crucial for rapid mobilisation and reduces side effects as well as the length of hospital stay. In this context, a variety of multimodal pain control regimes show good pain relief, including several nerve blocks, iPACK and local infiltration analgesia (LIA).
