Randomized Controlled Trial Comparative StudyIs pulmonary function affected by bilateral dual transversus abdominis plane block? A randomized, placebo-controlled, double-blind, crossover pilot study in healthy male volunteers.
Transversus abdominis plane (TAP) blocks have been shown to reduce postoperative pain after various abdominal surgical procedures in several studies. The motor nerves of the abdominal wall are located in the same plane as the sensory nerves affected by the TAP block. The aim of this study was to examine whether the application of an ultrasound-guided TAP block would affect the muscles of the anterior abdominal wall with respect to their function as accessory respiratory muscles and hence pulmonary function. ⋯ The administration of ultrasound-guided bilateral dual TAP blocks does not result in clinically relevant or statistically significant changes in the pulmonary function in healthy male subjects.
