Incidence and Etiology of Complications Associated With Peripheral Nerves Blocks

Procedures performed under regional anesthesia, especially peripheral nerve blocks (PNB) have increased markedly in recent decades. However, like any technical procedure, these techniques carry an implicit risk of complications.The main objective of the study is to determine the incidence of complications associated with peripheral nerve blocks and fascial blocks in Spain.

Inclusion Criteria:Age: 18-65 yearsASA I- IVBeing scheduled for surgery with peripheral and/or fascial nerve blocks as the basis of anesthesia or as part of a multimodal analgesic strategy.Exclusion Criteria:Refusal of the patient to participate in the studyContraindication for performing the regional technique (People with infections in the area of the skin where the puncture must be performed, allergy to anesthetics, severe blood coagulation disorders, previous nerve damage).Motor or sensory deficit prior to surgery in the metameric area susceptible to performing the block.
