Perioperative nerve injuries are recognized as a complication of regional anesthesia. Although rare, studies suggest the frequency of complications is increasing. Risk factors include neural, traumatic injury during needle or catheter placement, infection, and choice of local anesthetic solution. Neurologic injury due to pressure from improper patient positioning, tightly applied casts or surgical dressings, and surgical trauma are often attributed to regional anesthetic. Body habitus and preexisting neurologic dysfunction may also contribute. The safe conduct of regional anesthesia involves knowledge of patient, anesthetic, and surgical risk factors. Early diagnosis and treatment of reversible etiologies are critical to optimizing neurologic outcome.

Female genital prolapse, especially apical prolapse, significantly affects women's health and quality of life. Sacrospinous hysteropexy is a widely used surgical procedure to address this condition, presenting few postoperative complications. However, one of the reported complications is neuropathic pain resulting from damage to the branches of the pudendal nerve.

Background: Appendicectomy is a common procedure in children. Regional anaesthesia helps reduce requirements for opioids and hospital stay and enhances recovery. Laparoscopic-assisted Transversus Abdominus Plane block (L-TAP) was shown to be efficient and potentially superior to port site infiltration (PSI); however, this was not previously studied in paediatric appendicitis.

Anesthesiologists and the critical care team may be at increased risk of contracting severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2, COVID-19) due to airway manipulations and intubations performed during anesthesia administration and management of patient undergoing surgery. SARS-CoV-2 infections have been reported among healthcare workers. The virus is transmitted by close personal contact and aerosols.
