Abstract:
Objective:To investigate the effects of ultrasound-guided lumbar erector spinae plane block (L-ESPB) combined with general anesthesia using a laryngeal mask airway on postoperative delirium and early outcome in older adult patients undergoing hip arthroplasty.Methods:Sixty older adult patients who underwent unilateral total hip arthroplasty under general anesthesia using a laryngeal mask airway from August 2020 to May 2021 were included in this study. They were randomly assigned to observation and control groups, with 30 patients in each group. All patients underwent general anesthesia using a laryngeal mask airway. In the observation group, L-ESPB with 30 mL 0.375% ropivacaine was performed before induction of general anesthesia. Patient-controlled intravenous analgesia was performed in all patients after surgery. The Visual Analogue Scale score was > 4 points, and dezocine was intravenously injected for rescue analgesia. The amount of general anesthetics, the rate of use of vasoactive drugs, the time to pull out the laryngeal mask airway, length of stay in postanesthesia care unit, and the incidence of restlessness during the recovery period were recorded. Resting-state VAS score and Bruggrmann comfort scale score at 4, 8, 12, 24 and 48 hours after surgery, effective times of pressing the analgesia pump, the rate of rescue analgesia, the incidence of anesthesia-related adverse reactions at 48 hours after surgery, Pittsburgh Sleep Quality Index (PSQI) score at 1 day before and 1, 3 and 5 days after surgery, the incidence of postoperative delirium within 5 days after surgery, the time to get out of bed the first time, and the incidence of pulmonary infection were recorded.Results:The amount of remifentanil and propofol used during surgery were significantly lower in the observation group than those in the control group ( t = -6.80, -5.23, both P < 0.05). The rate of use of urapidil and esmolol were significantly lower in the observation group than those in the control group ( χ2 = 4.32, 5.46, both P < 0.05). The time to pull out the laryngeal mask airway, length of stay in postanesthesia care unit, and the time to get out of bed the first time in the observation group were (14 ± 2) minutes, (21 ± 2) minutes and (2.4 ± 0.5) days respectively, which were significantly shorter than those in the control group [(18 ± 2) minutes, (26 ± 3) minutes and (2.8 ± 0.7) days, t = -6.64, -7.18, -2.51, all P < 0.05]. The incidence of restlessness during the recovery period, postoperative delirium, and pulmonary infection in the observation group were 0.0%, 3.3% and 0.0% respectively, which were significantly lower than those in the control group [20.0%, 26.7%, 20.0%, all P < 0.05]. Resting-state VAS score at each time point was significantly lower in the observation group than that in the control group ( t = 3.32, 2.97, 4.33, 3.81, 3.10, all P < 0.05). Bruggrmann comfort scale score at each time point was significantly higher in the observation group than that in the control group ( t = 9.20, 8.62, 5.73, 5.72, 6.28, all P < 0.05). The effective times of pressing the analgesia pump, the rate of rescue analgesia, and the incidence of nausea and vomiting at 48 hours after surgery in the observation group were 0 (0, 0), 10.0% and 6.7% respectively, which were significantly lower than those in the control group [1(0, 2), 33.3% and 30.0%, Z = -3.41, χ2 = 4.81, 5.46, all P < 0.05]. PSQI score measured at 1, 3, and 5 days after surgery were significantly increased compared with those measured 1 day before surgery in each group ( F = 116.80, 325.64, both P < 0.001). PSQI measured at 1, 3 and 5 days after surgery was significantly lower than those in the control group ( t = -7.26, -6.41, -11.17, all P < 0.001). There were no significant differences in the incidence of dizziness, drowsiness, urinary retention and atelectasis between the two groups ( P > 0.05). Conclusion:Ultrasound-guided L-ESPB combined with general anesthesia using a laryngeal mask airway for hip arthroplasty in older adult patients can decrease the incidences of postoperative delirium and complications, which are conducive to early postoperative outcomes.
