[Gastrointestinal Tonometry in Orthopaedics (Results of a Prospective Randomized Pilot Study GATOAN-1 in Patients with General and Regional Anaesthesia During Replacement of the Hip Joint).].

In the submited pilot study the authors present a recently introduced method of monitoring of the regional perfusion by gastric tonometry during implantation of an endoprosthesis of the hip joint. The objective of the investigation was in addition to introduction of a new method to assess the influence of the type of anaesthesia on markers of the gastrointestinal tract perfusion. The method was used in 10 patients aged 27 - 75 years where in four instances a cemented endoprosthesis was implanted and an uncemented one in six cases.
