Objective: We aimed to evaluate Visual-Analogue-Scale (VAS) scores, hand-withdrawal, rash and skin eruptions after injections of different concentrations of rocuronium in intubation doses in alert patients using the isolated-forearm technique.Methods: Eighty ASA I-II patients were included in a randomized, controlled, single-blinded study. Two 20 G cannulas were inserted into the dorsum of the left and right hand in each patient. A tourniquet was applied to the left arm and inflated to 50 mm Hg above the patient's systolic blood pressure. Group 1 (n=20) received 2.5 mg mL -1 rocuronium diluted with 0.9% NaCl, Group 2 (n=20) received 5 mg mL -1 rocuronium diluted with 0.9% NaCl, Group 3 (n=20) received 10 mg mL -1 rocuronium and 0.4 mg mL -1 lidocaine mixture, and Group 4 (n=20) received 10 mg mL -1 rocuronium via a cannula on the left hand, provided that a dose of 0.6 mg mL -1 were given to all groups of patients. VAS 0 -VAS 60 values, hand-withdrawal, rash and skin eruptions were assessed in patients who were administered rocuronium but not under the effects of hypnotic or neuromuscular agents. Hemodynamic values were recorded both before and after the administration of hypnotic-neuromuscular agents.Results: VAS0 values were significantly higher in Group 4 when compared to Groups 1, 2 and 3 (p=0.032). No significant difference was observed between VAS0 and VAS60 values in Groups 1, 2 and 3. In Group 4, VAS 0 values were significantly higher than VAS 60 values (p=0.003). No significant difference was observed between groups in terms of side effects and hemodynamic values.
Conclusion:In conclusion, we determined that using rocuronium diluted with 0.9% NaCl was more effective in preventing injection pain than using a rocuronium-lidocaine mixture.Key Words: Rocuronium, intravenous injection, pain
AbstractThe patient was transferred to the operating room, and two 20-gauge cannulas were placed at the back of the patient's right and left hands at one attempt without causing any hematoma and 4 mL kg -1 of 0.9% NaCl infusion was started from the right hand. Age, weight and gender of the patients were recorded, and as a standard procedure ECG, SpO 2 , non-invasive arterial pressure monitoring was performed (Datex Ohmeda S/5 Avance) in the operating room. Patients were randomized into 4 groups. Group 1 (n=20) received 2.5 mg mL -1 rocuronium diluted with 0.9% NaCl, Group 2 (n=20) received 5 mg mL -1 rocuronium diluted with 0.9% NaCl, Group 3 (n=20) received a mixture of 10 mg mL -1 rocuronium and 0.4 mg mL -1 lidocaine, and Group 4 (n=20) received 10 mg mL -1 rocuronium, providing a total dose of 0.6 mg kg -1 in all groups. No analgesics were administered before rocuronium application. Drugs were prepared in 20 mL syringes by an anaesthetist other than the anaesthetist who would administer the drug. In order to provide double blind testing, the syringes were covered with a non-transparent foil in order to keep the anaesthetist who administered the drug, unaware about the concentration and content of the drug.In order to p...
