Effects of Ultrasound Guided Bilateral Obturator Nerve Block Combined with Midazolam Intravenous Anesthesia on Hemodynamics and Recovery Quality of Patients Underwent Bladder Cancer Surgery
Objective To investigate the effect of ultrasound guided bilateral obturator nerve block combined with mid-azolam intravenous anesthesia on hemodynamics and recovery quality of patients undergoing bladder cancer surgery.Methods A prospective randomized controlled study was conducted on 98 patients with bladder cancer who were admitted to the hospital for surgical treatment.They were divided into the control group and the study group by random number table,with 49 cases in each group.The control group was given midazolam intravenous anesthesia,and the observation group was given ultrasound guided bilat-eral obturator nerve block on the basis of the control group.The hemodynamics[heart rate(HR),Mean arterial pressure(MAP)],recovery quality[Steward recovery score,OAAS score for state of consciousness(OAAS)]and the dosage of midazo-lam were compared before anesthesia(T1),20 minutes after anesthesia(T2),40 minutes after anesthesia(T3),and at the time of extubation(T4)after surgery between the two groups.Results With the passage of time points T1,T2,T3,and T4,the levels of HR and MAP in both groups decreased,and the HR and MAP levels in the observation group at time points T2,T3,and T4 were higher than those in the control group(P<0.05).The Steward awakening score and OAAS score in the observation group were significantly higher than those in the control group(P<0.05).In the control group,the dose of midazolam was 5~10 mg,with an average of(7.64±1.23)mg.The dose of midazolam in the observation group was 5~8 mg,with an average of(6.65±0.55)mg.The dose of midazolam in the observation group was significantly lower than that in the control group(t=5.143,P<0.001).Conclusion Ultrasound guided bilateral obturator nerve block combined with midazolam intravenous anesthesia can improve the quality of recovery of patients undergoing bladder cancer surgery,and has little impact on hemodynamics,with good anesthetic effect.
