About

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.

Full description

Introduction. The number of procedures performed under regional anesthesia, especially peripheral nerve blocks (BNP) have increased notably in recent decades due to the improvement in pain control and the quality of post-anesthetic recovery that they provide. However, like any technical procedure, these techniques carry an implicit risk of complications.

Purpose. The main objective of the study is to determine the incidence of complications associated with peripheral nerve blocks and fascial blocks in Spain.

Material and methods. The postoperative results regarding the complications of regional anesthesia of peripheral nerves will be evaluated in a national audit of a prospective observational cohort in which hospitals at the state level in which these regional techniques are routinely performed will participate. A minimum sample size has been calculated on a population of 100,000 patients and a 95% confidence interval of 1,390, assuming a complication rate of 0.2% based on previous publications.

Inclusion criteria correspond to patients older than 18 years scheduled for surgery with a peripheral regional anesthesia technique as the basis of anesthesia or as part of a multimodal analgesic strategy.
