[Complications after regional anesthesia]. / Complicaciones tras técnicas de anestesia regional.

In recent years, there has been a considerable increase in the number of procedures carried out under regional anesthesia. The techniques used can be associated with a number of complications, which should be understood so that they can be recognized and managed appropriately. The overall incidence of reported complications associated with these techniques is low and therefore, with currently available data, we can only have an approximate idea of their incidence. The objective of this study is to systematically describe the complications that may arise from the use of neuraxial and peripheral regional anesthesia techniques.

Complicaciones tras técnicas de anestesia regional / Complications after regional anesthesia

En los últimos años se ha producido un incrementoconsiderable del número de procedimientos llevados acabo con técnicas de anestesia regional. Dichas técnicaspueden llevar asociadas una serie de complicacionescuyo conocimiento es importante para la identificación ycorrecto manejo de las mismas. La incidencia global decomplicaciones asociadas a la realización de dichas técnicases baja y por ello, y con los datos de que disponemosen la actualidad, sólo podemos aproximar su incidenciaexacta.En el presente trabajo se pretende ordenar esquemáticamentey describir las posibles complicaciones que sederivan de la realización de técnicas regionales tantoneuroaxiales como periféricas (AU)

[Accidental catheterization of the subdural space. Confirmation by radiological study]. / Cateterización accidental del espacio subdural. Confirmación por estudio radiológico.

We report two cases of accidental subdural blockade after peridural anesthesia. The blockade was detected postoperatively in both cases, two hours after start of continuous perfusion in one patient and eight hours afterwards in the other. Subdural diffusion was confirmed after injection of a radiopaque contrast medium. Subdural blockade usually manifests as an extensive neural block that is disproportionate to the amount of anesthetic injected. We discuss the need for frequent monitoring of metameric, sensory and motor levels to detect possible catheter misplacement, in addition to routine monitoring of heart rate, arterial pressure and oxygen saturation. When subdural blockade is suspected, epidural perfusion should be discontinued in order to prevent extensive sensory and motor blocks. A firm diagnosis can only be made by X-ray. A simple radiograph may adequately demonstrate subdural placement in some cases, although computed axial tomography should be performed when doubt arises.
