To investigate two concentrations of Ropivacaine in tourniquet reaction under axillary nerve block combined with musculocutaneous nerve block in patients undergoing forearm surgery.


510 cases of forearm trauma were divided into two groups, 285 cases in control group and 225 cases in experimental group. The control group was given 0.25% Ropivacaine 30ml under ultrasound guided axillary nerve combined with musculocutaneous nerve block, and the experimental group was given 0.5% Ropivacaine using same method. The onset of anesthesia, anesthetic effect, and duration of stay at the PACU, maintenance of effective analgesia, the adverse reaction rate, hemodynamic and tolerance of the tourniquet of the two groups were compared.


Mean arterial pressure, heart rate and blood oxygen saturation of the experimental group were better with significant (P <0.00) than control group; the amount of narcotic drugs, onset time of anesthesia and the VAS score was lower in the experimental group with statistically significant (P<0.00). The rate of excellent and good effect of anesthesia in the experimental group was 100% higher than that the control group, the duration of stay in the PACU was shorter in the experimental group (p<0.00); the duration of analgesia was shorter, and the adverse incidence rate in the experimental group was lower than the control group (p<0.00).


he application of 0.5% Ropivacaine compare to 0.25% Ropivacaine can improve the hemodynamic stability and reduce the tourniquet pain significantly and improve anesthetic effect, reduce the incidence of adverse reactions, shorten the onset time of anesthesia.

Key words:

Ultrasound guided axillary nerve block, upper limb surgery, tourniquet syndrome, Ropivacaine , anesthesia efficacy
