Abstract：Objective To observe the efficacy of applying monitors to test anesthesia depth and muscle relaxants in da Vinci robotic thyroid surgery.Methods 70 patients who underwent elective thyroid surgery were selected, and randomly divided into two groups:group A was combined da Vinci robotic thyroid surgery with monitors testing anesthesia depth and muscle relaxants ( n=35);while group B underwent the traditional thyroidectomy with micro laparoscope ( n=35 ) .Changes of HR, MAP were observed at the time of pre-administration ( T0 ) , intubation ( T1 ) , cutting skin ( T2 ) , insufflating CO2 ( T3 ) , separating tumors ( T4 ) , completing CO2 insufflations ( T5 ) , extubation ( T6 ) .Dosage of drugs during surgery, awakening time and extubation time were observed during anesthesia.Results (1) Mean HR of two groups on each of all the other time points except T3 were compared, the differences were all statistically significant ( P<0.0001);the mean MAP of two groups on each time point were compared, the differences were all sta-tistically significant (P<0.0001).(2) Mean HR of T1, T3, T5 were compared with that of T0 in group A, the differences were all statistically significant ( P<0.008);the other time points except T3 were all compared with that of T0 , the differences were statistically significant in group B (P<0.008).(3) Mean MAP on each of the other time points except T3 were compared with that of T0 in group A, the difference were statistically significant (P<0.008);mean MAP of all time points were compared with that of T0 in group B, the differences were statistically significant (P<0.008).(4) The dosages of propofol, atracurium in group A was less than those of group B, the differences were statistically significant ( P<0.05);there was no statistically significant difference in the dosage of fenta-nyl between two groups;the time of awakening and extubation in group A were both shorter than that in group B, the differences were statistically significant (P<0.05).Conclusions The method of using muscular relaxation monitor to test the anesthesia depth during da Vinci robotic surgery can effectively monitor HR and MAP, reduce the amount of general anesthetic, shorten the time of postopera-tive revival with high safety, and provide better monitoring for depth of anesthesia and level of muscular relaxation.
