Aim: The purpose of the study is to verify the hypothesis that there is a correlation between the degrees of myorelaxation obtained by neuromuscular blockage during general anesthesia with changes in IAP values.

Material and methods: The present study was carried out in surgery department, during September 2016 - October 2016. The plot consisted of 9 patients who undergone surgeries in the extra-abdominal area: 2 total thyroidectomies, 3 subtotal thyroidectomies, 3 simple mastectomy and one axilo-femoral bypass.

Results: By comparing the results obtained in the nine cases, it was observed a statistically insignificant increase of intraabdominal pressure at train of four ratio values of 0, 1 or 2, intraabdominal pressure instead showed statistically significant variations in train of four ratio values of 3 or 4, observed especially at the reversal of anesthesia and patient waking up.

Conclusions: Train of four ratio is an accurate indicator of the degree of neuromuscular blockage. Train of four ratio values of 0-2 changed statistically insignificant the intra-abdominal pressure. Increase train of four ratio over 3 led to sudden increases in intra-abdominal pressure.
