Diaphragm Ultrasound to Evaluate the Antagonistic Effect of Sugammadex

Diaphragm Ultrasound to Evaluate the Antagonistic Effect of Sugammadex on Rocuronium After Liver Surgery in Patients With Different Liver Child-Pugh Grades

The use of muscle relaxants is an indispensable in the general anesthesia but is prone to accidents, which are often related to residual muscle relaxant. Therefore, how to timely and effectively eliminate the residual effect of muscle relaxants after surgery has become an urgent clinical problem. Rocuronium is a non-depolarizing muscle relaxant that is primarily metabolized by the liver. Patients with liver dysfunction can affect the metabolic process of rocuronium, thereby delaying the recovery of muscle relaxation. Sugammadex (SUG) is a novel specific antagonist of aminosteroid muscle relaxants, which can effectively antagonize muscle relaxants at different depths. However, whether liver dysfunction affects the antagonistic effect of SUG against rocuronium has not been reported yet. Therefore, the investigators hypothesize that with the increase of patients' liver Child-Pugh grade, the recovery time of rocuronium antagonized by the same dose of SUG after surgery will be prolonged, and the incidence of muscle relaxation residual will be increased in the short term.

Study Overview

• Status: Recruiting
• Conditions: Liver Dysfunction; Rocuronium; Sugammadex; Diaphragm Ultrasonography
• Intervention / Treatment: Drug: sugammadex

Detailed Description

Main instruments: Drager Fabius anesthesia machine, interlive vue MX600 monitor, Train-Of-Four-Watch muscle relaxation monitor, Philips IU22 Color Doppler Ultrasound Diagnostic Instrument.

Diaphragm ultrasound scan: Prior to anesthesia induction, patients will lie on the bed in a semi-recumbent (45°) position. One operator skilled in ultrasonography will identify and locate diaphragm using the hyperechoic pleural and peritoneal layers with an Philips IU22 Color Doppler Ultrasound Diagnostic Instrument.

Anesthesia method: After the patient entered the operating room, venous access will be opened in the forearm, and routine monitoring of non-invasive BP, ECG, oxygen saturation(SpO₂) and bispectral index(BIS) will be performed. During anesthesia induction, propofol 2.5mg/kg and sufentanil 5μg/kg will be injected intravenously. When the BIS value drops below 60, the muscle relaxation monitor will be calibrated. After T1 and TOF are stable, rocuronium will be injected intravenously at 0.6 mg/kg. By the time T1=0, endotracheal intubation will be given, and the respiratory parameters will need to be adjusted to volume control ventilation (VT 8-10 ml/kg, respiratory rate(RR) 12-18 times/min, and PETCO2 35-45 mmHg). During the maintenance stage of anesthesia, the pneumoperitoneum pressure will be at a low level of 8-10mmHg, propofol target-controlled infusion(TCI) will be applied to maintain the plasma concentration of 2.5-5.5 μg/mL, remifentanil TCI will be used to keep the plasma concentration of 0.5-5 ng/mL, and rocuronium will be continuously pumped intravenously with 0.3-0.6 mg/kg/h for deep muscle relaxations, with the the post-tetanic twitch count (PTC) value of 1 to 2.

Muscle relaxation monitoring: TOF-Watch SX muscle relaxation monitor is going to be adopted in our study. The investigators will standardize the electrode position of the muscle relaxation monitor. The distal electrode will be placed at the intersection of the radial edge of the ulnar flexor carpi and the proximal edge of the wrist curve, while the proximal electrode will be placed 3-6 cm away from the distal electrode. Two electrodes will put on either side of the predicted location of the ulnar nerve, which will be able to minimize the impact caused by misjudgment of the location of the nerve.

Measurement of diaphragmatic thickness: When B-mode ultrasound will be used to measure the thickness of the diaphragm, a 5-12MHz linear array ultrasound probe will be put in the left midaxillary line between the 8-10 costale, where is called the diaphragmatic zone of apposition (ZAP). In the breathing exercise, the diaphragm is relatively fixed at ZAP, and the breathing action has little influence on the movement of the diaphragm at ZAP, the diaphragm only shows systolic and diastolic changes. Therefore, the measurement of the diaphragm thickness at ZAP can truly reflect the overall thickness change of the diaphragm during the respiratory cycle. Each value will be measured three times in three consecutive breathing cycles, and the average of the nine measurements will be taken. The values of diaphragmatic thickness at the end of inspirations (DTEI) and diaphragmatic thickness at the end of expirations (DTEE) will be recorded respectively, then the change rate of diaphragmatic thickness fraction (DTF) = (DTEI - DTEE) / DTEE × 100% will be calculated. In addition, the recover rate of DTF = (pre-anesthetic DTEI - postoperative DTEI) / pre-anesthetic DTEI × 100% also will be figured out. Ultrasound measurements should be performed by two physicians with ultrasound experience. Results will be kept confidential to the investigator, who will analyze the ultrasound data when the research is over.

The infusion of anesthetic drugs should be stopped at the end of surgery, and the patients will be transferred into the Post-Anesthesia Care Unit (PACU) with endotracheal catheters and continued monitoring. When the TOF value was ≥2%, patients in each group will be given SUG (2mg/kg), respectively. The researchers will record the recovery conditions of diaphragmatic function monitored by bedside ultrasound at the immediate time,10min, 30min and 2h after extubation.
