Minimal invasive surgery in small ruminants: Laparoscopically performed cystostomy, alveolar recruiting-maneuver and pharmaco-kinetics of Lidocain in sheep and goat

Laparoscopic guided cystostomy catheter placement (surgical part):
The advantages of laparoscopy are the possibility of an excellent observation of the ventral abdominal cavity, a shorter duration of surgical procedure, its minimally invasive nature (minor trauma in comparison to conventional laparotomy) as well as faster recovery. Therefore the aim of this study is to establish a laparoscopic operation technique to install an urinary catheter under visible control. In future this technique should displace the commonly used laparotomy in patients with urolithiasis.
Recruitment maneuver (anaesthesia research part):
The aim of this study is to compare classical mechanical ventilation with optimalized ventilation after Recruitment Maneuver (RM) in sheep anaesthetized for laparoscopic cystostomy. This is to clarify the question if RM and optimalized ventilation can treat atelectasis and prevent further atelectasis development.
Lidocaine-pharmacokinetics (pharmacological research part):
Our goal is to establish an experimental approach to evaluate the hypothesized alteration of general pharmacokinetic parameters of lidocaine (e.g. volume of distribution, total clearance, elimination half-life) in sheep and goats during both analgesia/anaesthesia and pneumoperitoneum, respectively.
