Short-term elevation of intracranial pressure does neither influence duodenal motility nor frequency of bolus transport events: a porcine model.

Background: Patients with traumatic brain injuries and raised intracranial pressure (ICP) display biphasic response with faster gastric emptying during the early stage followed by a prolonged gastric transit time later. While duodenal contractile activity plays a pivotal role in transpyloric transit we investigated the effects of raised intracranial pressure on duodenal motility during the early phase. In order to exclude significant deterioration of mucosal blood supply which might also influence duodenal motility, luminal microdialysis was used in conjunction.

Effects of a single dose of ketamine on duodenal motility activity in pigs.

In order to investigate the effects of a single dose of ketamine on duodenal motility, the present study focused on the electric impedance technique. Five pigs (32 to 40 kg, CVC group) were instrumented with a central venous catheter 1 d before measurements. The next day, general anesthesia was started and maintained via central venous catheter by propofol and fentanyl.

[Medical malpractice from the viewpoint of the insurer].

The task of the insurer for medical liability insurance is to care about the interests of the contract partner by defending unjustified claims, satisfying claims of compensation of harmed patients, and supporting the medical society in developing methods to prevent harm. The criminal law and the liability law are demonstrated.
