Objective: To investigate the effects of ultrasoundguided realtime precise caudal block combined with laryngeal mask airway (LMA) general anesthesia on intraoperative stress response and postoperative bowel function recovery in patients undergoing vaginal hysterectomy. Methods: This prospective, singlecenter randomized controlled trial enrolled 108 patients who underwent elective vaginal hysterectomy in our hospital from January 2023 to January 2025. They were randomly divided into a control group (n=54) and an observation group (n=54). The control group received LMA general anesthesia alone, while the observation group received ultrasoundguided realtime precise caudal block (0.25% ropivacaine 20 mL) combined with LMA general anesthesia. The following parameters were compared between the two groups: hemodynamic variables [mean arterial pressure (MAP), heart rate (HR)] at different intraoperative time points, stress response indicators [serum cortisol (COR), norepinephrine (NE), blood glucose (GLU)], postoperative bowel function recovery indicators (time to bowel sound recovery, time to first defecation, time to first flatus), postoperative pain Visual Analog Scale (VAS) scores, effective pressing times of patientcontrolled analgesia (PCA) pump, rescue analgesia rate, and incidence of adverse reactions. The primary outcome was the 24 h postoperative VAS score; secondary outcomes included intraoperative stress response indicators and postoperative bowel function recovery indicators. Results: No significant differences were found between the two groups in age, BMI, operative time, or intraoperative blood loss (P>0.05). Compared with T0, MAP and HR at T1, T2 and T3 were increased in both groups, but the MAP and HR at T1, T2 and T3 in the observation group were significantly lower than those in the control group (P<0.05). Levels of COR, NE and GLU at T1, T2 and T3 were higher than those at T0 in both groups, but the levels in the observation group were significantly lower than those in the control group at the corresponding time points (P<0.05). The time to bowel sound recovery, time to first defecation and time to first flatus in the observation group were significantly shorter than those in the control group (P<0.05). The VAS scores at 2 h, 6 h, 12 h and 24 h postoperatively in the observation group were significantly lower than those in the control group (P<0.05); the effective pressing times of PCA pump and the rescue analgesia rate in the observation group were also significantly lower than those in the control group (P<0.05). The incidence of postoperative nausea and vomiting (PONV) in the observation group was significantly lower than that in the control group (P<0.05), whereas no significant difference was observed in the incidence of urinary retention between the two groups (P>0.05). Conclusion: Ultrasoundguided realtime precise caudal block combined with LMA general anesthesia can effectively alleviate intraoperative stress response, maintain hemodynamic stability, promote postoperative bowel function recovery, and improve postoperative analgesia quality in patients undergoing vaginal hysterectomy, without increasing the incidence of adverse reactions. Therefore, this combined anesthesia technique is worthy of clinical application.

Objective To investigate the best time for endotracheal suction and the feasibility of on-demand suction in general anesthesia patients of post anesthesia care unit (PACU).Methods A total of 240 selective surgical patients who underwent oral endotracheal intubation with general anesthesia from June 2021 to October 2021 were selected.They were randomly divided into group A (sputum suction before extubation),group B (sputum suction in the room),and group C (in-room sputum suction on demand),80 cases in each group.In group A,routine airway and oral sputum suction was performed before removing the catheter when the patients were waking up.Group B had sputum sucked in the airway and mouth before entering the PACU,removed the catheter when waking up,and cleaned the oral cavity after extubation.In group C,the patients were assessed with reference of suction indications after entering the room.Sputum suction was performed for those with indications,but not for those without indications,and the mouth was cleaned after removing the catheter when awaken.Patient's heart rate,blood pressure,coughing,nausea and vomiting and airway spasm caused by tracheal irritation in 1 minute after suction and extubation were recorded after the patients entered the PACU.The tremor score and sore throat score were recorded and analyzed.Results Comparing group A with group B,each patient had sputum suction.The heart rate,blood pressure,and oxygen saturation of group A changed more significantly than group B after sputum suction and extubation (P<0.05).In terms of airway stress response,20 patients in group C needed suction,none in the three groups had airway spasm.Two patients in group A had vomiting due to severe coughing during extubation.The patients of coughing in group C were significantly less than that of group A and group B,respectively (P<0.05).The dysphoria caused by airway stimulation and postoperative throat pain in group C was significantly lower than that of group A (P<0.05).Conclusions The patient on-demand suction when enter the room,and no suction when extubation,can reduce the patient's cardiovascular and airway stress response and reduce postoperative sore throat.

Objective To observe the effect of different doses of compound musk injection before operation on early mild cognitive impairment (MCI) in elderly patients after general anesthesia. Methods We selected 120 cases of lower limb and lower abdominal surgery general anesthesia (ASA level Ⅰ-Ⅱ),and divided them randomly into 4 groups: Group Ⅰ (n=30,control): 0.9% saline 100mL intravenous infusion; Group Ⅱ (n=30): low dose compound musk injection (0.1 mL/kg,add 0.9% saline 100 mL), 0.5h before the start of surgery, intravenous drip, the rate was 200 mL/h; Group Ⅲ (n=30): medium dose compound musk injection (0.2 mL/kg), the same as group Ⅱ in drug compatibility,treatment time and injection rate; Group Ⅳ (n=30): high dose compound musk injection (0.3 mL/kg), the same as group Ⅱ in drug compatibility, treatment time and injection rate. Each premedication, induction of anesthesia, anesthesia depth,intraoperative awake and anesthesia medication were the same. And we observed each group about preoperative and postoperative CCSE,FAQ and MMSE(mini-mental state examination) score of the 1st days,3rd days and 7th days. Results In the 4 groups of patients,the operation time,anesthesia time,intraoperative blood loss,recovery time were basically the same (P>0.05); CCSE,FAQ,MMSE cognitive function scores of 4 groups were reduced after operation on the first day,the third day and the seventh day; group Ⅱ,group Ⅲ,group Ⅳ decreased slightly.The scores were higher than group Ⅰ (P<0.05),and there were no significant differences between group Ⅱ,group Ⅲ and group Ⅳ (P>0.05); The incidence of MCI in first days, third day and seventh day after operation respectively was: group Ⅰ 66.7%,33.3% and 16.7%; group Ⅱ 50%,16.7% and 6.7%; group Ⅲ 50%,16.7% and 6.7%; group Ⅳ 46.7%,20% and 10%.Those of the drug groups were lower than group Ⅰ (P<0.05), but there was no significant difference between group Ⅱ, group Ⅲ and group Ⅳ (P>0.05).There were no significant differences in the 4 groups in postoperative adverse reactions. Conclusion Preoperative intravenous infusion of compound musk injection 0.1 ml/kg, may effectively reduce the incidence of MCI in elderly patients after general anesthesia. Increasing musk injection dose (0.2 ml/kg,0.3 ml/kg and 0.4 mg/kg) was no synergistic effect on MCI in elderly patients,0.1ml/kg is enough.
