Clinical Trial Summary

Chemotherapy causes motor nerve dysfunction and degeneration that may alter the response to neuromuscular blocking drugs. To analyse the risk of residual neuromuscular block (RNMB) induced by rocuronium given in standard doses to patients who undergo chemotherapy within three months.


Description:

Rocuronium, as a non depolarizing muscle relaxant with medium time effect, takes effect rapidly. It is an ideal neuromuscular blocker to replace succinylcholine for induction of tracheal intubation and maintenance of muscle relaxant under general anesthesia. Sevoflurane is widely used in clinic because of its low blood gas partition coefficient, rapid and stable induction and recovery, easy adjustment of anesthesia depth and strong controllability. In addition, the number of patients receiving preoperative adjuvant chemotherapy for malignant tumors is increasing year by year in China. The commonly used chemotherapy drugs, such as paclitaxel, platinum, vinorelbine, etc., have dose-dependent peripheral neurotoxicity. Therefore, to explore and study the influence of pathophysiological changes of patients receiving chemotherapy on the neuromuscular relaxation effect of sevoflurane combined with non depolarizing neuromuscular blockers, It is very important for anesthesia, resuscitation and perioperative management of chemotherapy patients. The purpose of this study is to reveal the effect of sevoflurane on rocuronium neuromuscular blockade in chemotherapy patients by comparing the difference of rocuronium neuromuscular blockade effect of sevoflurane and total intravenous anesthesia in chemotherapy patients and non chemotherapy patients, and to provide information for more safe and rational application of rocuronium in clinical anesthesia of chemotherapy patients.

Intervention

Drug:
sevoflurane anesthesia
Sevoflurane enhances the effects of rocuronium and significantly prolongs the duration of action of rocuronium and the time to recovery.
Propofol Injection
Propofol is most commonly used for intravenous anesthesia. In contrast to sevoflurane, propofol has no effects on rocuronium.
