Reduction of Rocuronium-induced Injection Pain With Aspiration of Blood

November 27, 2023 updated by: Chang Gung Memorial Hospital

The goal of this clinical trial is to learn about reduction of rocuronium injection pain in participants receiving general anesthesia. The main question aims to answer is whether diluting rocuronium with blood can reduce rocuronium injection pain. Rocuronium is a rapid onset muscle relaxant used in general anesthesia. Lidocaine is a local anesthetic. Researchers will

• inject diluted rocuronium in participant's intravenous catheter during induction. • record withdrawal movement and rocuronium onset time and duration measured by train-of-four (TOF).

Researchers will compare between rocuronium diluted with blood, lidocaine and normal saline to see if blood can reduce rocuronium injection pain.

Study Overview

Detailed Description

This clinical trial uses a random table for sequential randomization, randomly assigning subjects to 3 groups, each consisting of 40 participants.

Researcher will confirm the patency of peripheral intravenous lines before induction. If peripheral intravenous lines cannot be used, they will be readministered at another injection site. If there are difficulties in peripheral intravenous injection, the participant will need to withdraw from this clinical trial. The neuromuscular monitoring device (NMT) is installed before the start of the clinical trial to monitor the effects of the drug. To avoid influencing the final results, fentanyl and 2%lidocaine will not be administered before injecting rocuronium. Anesthesia induction begins with the administration of oxygen through a mask to assist breathing. Initially, propofol is injected at a dose of 1.5 to 2mg/kg. Once the participant is confirmed to have lost consciousness, researchers will inject diluted rocuronium immediately, with an injection speed of 10 to 15 seconds. The dose of rocuronium for each participant is 0.8 mg/kg. The first group is pre-diluted with 2mL of normal saline, the second group with 2mL of 2%lidocaine, and the third group with 2mL of the participant's blood. To avoid clotting of blood, the procedure of the third group involves using a syringe containing rocuronium to withdraw 2mL of blood from the vein, followed by simultaneous injection into the intravenous line. The NMT is used to monitor the drug's effects, defining the onset time as the time from rocuronium injection to the disappearance of train-of-four (TOF) count T1 and the duration of action as the time from rocuronium injection to the appearance of TOF count T1.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame

From enrollment to the end of assessment at thirty minutes.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame

onset time is defined by injection of rocuronium mixture to the disappearance of Train-of-four count T1.
From enrollment to the end of assessment at 3 minutes.
duration of action
Time Frame: From enrollment to the end of assessment at one hour.
Duration of action is defined by injection of rocuronium mixture to appearance of Train-of-four count T1.
From enrollment to the end of assessment at one hour.
