Abstract:
Objective To investigate the anesthetic effects of different opioid drugs combined with remifentanil for holmium laser lithotripsy of the ureter.
Methods Eighty patients scheduled by transurethral holmium laser lithotripsy were randomly divided into the group A(40 cases) and group B(40 cases) using a random number table method.Group A received anesthesia with fentanyl combined with remifentanil during surgery, while group B received anesthesia with sufentanil combined with remifentanil.The operation time, eye opening time after discontinuation of medication, laryngeal mask removal time, 24-hour postoperative pain score and hospital stay in two groups were recorded.The mean arterial pressure(MAP), heart rate(HR) and bispectral index(BIS) at different time points before anesthesia induction(T0), during laryngeal mask insertion(T1), at the beginning of surgery(T2) and during laryngeal mask removal(T3) in two groups were recorded.The serum levels of inflammatory factorsC-reactive protein(CRP), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α) at T0, 30 minutes after successful induction(T4) and 60 minutes after successful induction(T5) were compared between two groups.The Steward recovery score, modified OAA/S score, and incidence of adverse reactions at 10 minutes and 30 minutes after discontinuation of medication were compared.
Results The eye opening time and laryngeal mask removal time in group A were shorter than those in group B after discontinuation of medication(P < 0.01 and P < 0.05).There was no statistical significance in the surgical time, postoperative pain score and postoperative hospitalization time between two groups(P > 0.05).The MAP, HR and BIS in two groups at time points T0, T1, T2 and T3 were compared, and there was no statistical significance in the levels at each time point between two groups(P > 0.05).The differences in the BIS levels in two groups at different time points were statistically significant(P < 0.01), while there was no statistical significance in the MAP and HR at each time point within group(P > 0.05).The comparison results of CRP, IL-6 and TNF-α levels at time points T0, T4 and T5 within the group showed that there was no statistical significance in the CRP and TNF-α levels in group A(P > 0.05), while there was statistical significance in the IL-6 levels(P < 0.01).The differences of the three indicators in group B at different time points were statistically significant(P < 0.01), and showed an upward trend over time.The intergroup comparison showed that except for IL-6, which had no statistically significant difference at time point T4(P > 0.05), the levels of the three indicators at time points T4 and T5 in group A were all lower than those in group B(P < 0.01).The Steward recovery scores and modified OAA/S scores in group A at 10 minutes and 30 minutes after drug withdrawal were higher than those in group B(P < 0.01).There was no statistical significance in the incidence of adverse reactions between two groups(P > 0.05).
Conclusions The anesthetic effects of fentanyl combined with remifentanil and sufentanil combined with remifentanil on patients treated with holmium laser lithotripsy of the ureter are comparable.The postoperative recovery effect is good, the safety is high, and the inhibitory effect on inflammatory response is significant.
