Continuous Infusion and Bolus Doses of Rocuronium During Lumbal Discectomy, Muscle Strength and Patient Recovery
- Registration Number
- NCT04236050
- Lead Sponsor
- Clinical Hospital Centre Zagreb
- Brief Summary
The continuous infusion of rocuronium during general anesthesia for a lumbar discectomy enables better muscle strength recovery, and a better quality of patient recovery as measured by questionnaire.
- Detailed Description
Rocuronium is a non-depolarising neuromuscular blocking agent that can be administered in bolus doses or via continuous infusion during general anesthesia. Due to the specificity of the knee-chest position in a lumbar discectomy, many complications during anesthesia and surgery are possible. Therefore an effective and balanced intraoperative neuromuscular block is needed.
Studies so far have not included a comparison on muscle strength and quality of patient recovery of the effect of continuous infusion and bolus doses of rocuronium during anesthesia for lumbar discectomy.
The hypothesis of this research was that the continuous infusion of rocuronium during general anesthesia for a lumbar discectomy enables better muscle strength recovery, and a better quality of patient recovery as measured by questionnaire.
The aim was to compare the influence of the continuous infusion and bolus doses of rocuronium on patient recovery. Therefore the investigators assessed how continuous infusion and bolus doses of rocuronium affect the recovery of muscle strength as measured by a hand-grip dynamometer. The quality of patient recovery was assessed by standardised questionnaire (Qor-40 - Quality of recovery questionnaire).
The aim was also to evaluate the applicability of the Croatian version of Qor-40 questionnaire in clinical practice.

Group Intervention Description rocuronium is administered via continuous infusion Rocuronium 40 patients. General anesthesia is maintained with propofol and remifentanil, with standard anesthetic monitoring, bispectral index (BIS) and train-of-four(TOF). In experimental group, rocuronium was administered via continuous infusion so that theTOF ratio was 5%. Hand-grip muscle strength was measured with a dynamometer on three occasions: before general anesthesia, in the early post-anesthesia period in the operating room, and 24 hours after anesthesia. The quality of patient recovery was assessed with a Qor-40 questionnaire before anesthesia, 24 hours after anesthesia, and 30 days after anesthesia and surgery rocuronium is administered in bolus doses Rocuronium 40 patients. General anesthesia was maintained with propofol and remifentanil, with standard anesthetic monitoring, BIS and TOF. In this group, rocuronium was administered in separate bolus doses with the TOF ratio of 5%. Hand-grip muscle strength was measured with a dynamometer on three occasions: before general anesthesia, in the early post-anesthesia period in the operating room, and 24 hours after anesthesia. The quality of patient recovery was assessed with a Qor-40 questionnaire before anesthesia, 24 hours after anesthesia, and 30 days after anesthesia and surgery
