Influence of Analgesia and Neuromuscular Block on Abdominal Distension and Operating Conditions Laparoscopic Operations

measurement of change in abdominal wall length \[cm\] during neuromuscular block with a measuring tape.

Measurement of the time course of the neuromuscular block: neuromuscular transmission is measured by assessment of the post tetanic count and the train of four ratio using acceleromyography (TOF Watch SX™, Essex Pharma GmbH, Munich, Germany) at the right adductor pollicis muscle with transcutaneous Ag/AgCl electrodes (electrocardiogram electrodes; Ambu Inc., MD 21060 USA);
