Study protocol for a randomised, patient- and observer-blinded evaluation of P6 acustimulation for the prevention of nausea and vomiting in the postoperative period in patients receiving routine pharmacological prophylaxis (P6NV-Trial).

Background: The efficacy of pericardium 6 (P6) acupoint stimulation to reduce the incidence of postoperative nausea and vomiting (PONV) has been proven in several randomised controlled clinical trials. However, little is known about the effectiveness in daily practice and its use in combination with traditional pharmacologic approaches.

Methods: The primary objective of the P6NV study is to determine whether intraoperative acustimulation (acupuncture or acupressure) at the point P6 provides additional benefit when applied along with customary prophylactic intravenous antiemetics administered according to the local standard operating procedures (SOP).

[Anaesthesiologic Techniques for Patients at Risk of Aspiration].

Rapid sequence induction and intubation (RSII) is the appropriate method of inducing general anaesthesia in patients who are at a risk of aspiration. The classical RSII is limited to a few treatment recommendations which are rarely based on evidence-based findings. New techniques (e.
