Trial Outcomes & Findings for Optimizing Surgical Conditions During Laparoscopic Herniotomy With Deep Neuromuscular Blockade (NCT NCT02247466)

NCT ID: NCT02247466

Last Updated: 2019-07-02

Results Overview

Improvement of surgical workspace (rated on a 5-point scale) estimated as the difference between the workspace during deep NMB and the workspace without NMB. Ratings are performed in the same patient during stable pneumoperitoneum at 12 mmHg. (1 Extremely poor conditions; 2 Poor conditions; 3 Acceptable conditions; 4 Good conditions; 5 Optimal conditions)

Measure
Group A - Saline, Assesment, Rocuronium and Assesment
Intervention after intubation and placement of trocars without NMB. Bolus of saline (placebo) 6mL (TOF 100%) the surgeon assesses the surgical workspace with pneumoperitoneum 12 mmHg. After administration of rocuronium 0.6 mg/kg when TOF=0 the surgical workspace is assessed again Rocuronium and Sugammadex
Group B - Rocuronium, Assesment, Sugammadex and Assesment
Intervention after intubation and placement of trocars without NMB. Bolus of rocuronium 0.6 mg/kg when TOF=0 the surgeon assesses the surgical workspace with pneumoperitoneum 12 mmHg. Three minutes after administration of sugammadex (TOF 100%) the surgical workspace is assessed again Rocuronium and Sugammadex
