RESUMEN
Objective To investigate the advantages and disadvantages of oxycodone combined subarachnoid block and intravenous-inhalational anesthesia in elderly patients with femoral trochanter fracturethe surgery.Methods Thirty-four patients undergoing elective surgery with closed reduction and Proximal femoral nail anti-rotation (PFNA) fixation,13 males and 21 females,aged 76-92 years,ASA physical status Ⅱ or Ⅲ,were equally randomized into two groups (n =17 each):group O and group C.Patients in group O received oxycodone combined subarachnoid block.Patients in group C received intravenous-inhalational anesthesia.Patients in group C were not premeditated beforel entering the operation room.After entering the rooms group O was given oxycodone 3-5 mg i.v first,then given ropivacaine in subarachnoid space.All patients were induced with intravenous of sulfentanil 0.2-0.3μg/kg,cisatracurium 0.15 mg/kg,etomidate 0.1-0.2 mg/kg slowly.Anesthesia was maintained by intravenous propofol 3-5 mg· kg-1 · h-1,remifentanyl 0.1-0.3 μg · kg-1 · h-1,sevofrane 0.55％-2％ infusion,intravenous bolus cisatracurium 0.05-0.10 mg/kg.The anesthesia related complications and length of hospital stay were recorded.Results Postoperative nausea and vomiting (PONV) respiratory depression of group O was significantly lower than that of group C [2(11.8％) cases vs 9 (52.9％) cases,P＜0.05],length of hospital stay of group O was significantly shorter than that of group C [(10.4±1.6) d vs (15.8±2.0) d,P＜0.05].Conclusion In the elderly patients with femoral intertrochanteric fracture closed reduction and PFNA internal fixation,oxycodone combined subarachnoid block may improve patients' recovery.
RESUMEN
Objective The objective of this study was to observed the effect of target control intravenous (TCI) anesthesia and intravenous inhalational anesthesia in the postoperative cognitive function in elderly patients with intracranial tumor at different time points.Methods Seventy patients were divided into the experimental and control groups according to the different methods of intraoperative anesthesia.The experimental group was selected to treat with propofol combined with remifentanil TCI anesthesia,and the control group was treated with intravenous anesthetics combined with inhalation isoflurance.Recovery time of respiration,time of opening eyes,extuation time,orientation recovery time,OAAS score before and after operation,and cognitive function (MMSE)were observed in two groups.Results They were no differences in the recovery time of respiration,time of opening eyes and extubation time in two groups (P ＞ 0.05).The orientation recovery time in the experimental group was 20.4 ± 5.8 min and 23.2 ± 4.3 min in the control group.They had significantly different between experimental and control groups (P ＜ 0.05).The time of extubation,leaving the operating room and after 1 h of extubation,OAAS point for the experimental group was 3.3 ± 0.5,4.2 ± 0.4,4.6 ± 0.6 min,respectively,and 2.3 ± 0.2,3.3± 0.4,3.9 ± 0.3 in the control group,respectively.They were significantly different between the experimental and control groups(P ＜ 0.05).Prior to treatment,there was no significant difference in MMSE score between the two groups(P ＞0.05).MMSE score was 25.0 ±0.4 and 27.9 ± 1.1 in the experimental group after treatment for 24 h and 48 h,respectively.MMSE score in the control group was 23.2 ±0.9 and 25.8 ± 1.3 after treatment for 24 and 48 h,respectively.There had a significant different from two groups (P ＜ 0.05).Conclusion For elderly patients with intracranial tumor surgery,TCI anesthesia with propofol and remifentanil is stable and awake,and the effect on postoperative cognitive function is relatively small.
RESUMEN
Objective To explore the effect of propofol-remifentanil total intravenous anesthesia in cosmetic surgery and the controllability of anesthesia.Methods According to the American Society of Anesthesiologists (ASA),levels Ⅰ-Ⅱ hospitalized patients for elective cosmetic surgery (100 cases) were randomly divided into two groups,namely propofol-remifentanil total intravenous anesthesia group (Group T) and combined intravenous inhalational anesthesia group (Group C),50 cases each.Observatory items of patients included intraoperative cardiovascular drug use,body movement,waking-up time,extubation time,leaving time from operation theatre,postoperative adverse reaction,hypoxemia (SpO2＜95％) and anesthesia satisfaction.Results In Group C,waking-up time,extubation time and leaving time from operation theatre were (12.2 ± 3.6),(13.8± 4.6) and (4.6 ±5.8) min,respectively,which were longer than those (6.7±2.6),(7.8±3.3) and (3.3±3.8) min in Group T (P＜0.05).In Group T,intraoperative ephedrine usage (6/50,12.0％) and body moving rates (4/50,8.0％) were higher than those (1/50,2.0％) and (1/50,2.0％) in the Group C (P＜0.05).The Group T had lower incidence of postoperative adverse reactions,including lethargy (2/50,4.0％),irritability (1/50,2.0％),nausea and vomiting (8/50,16.0％),which were lower than those (8/50,16.0％),(7/50,14.0％) and (17/50,34.0％) in the Group C (P＜0.05).The incidence of postoperative chill was similar between the two groups with no statistical significance (P＞0.05).Satisfactory rate with anesthesia was 84.0％ (42/50) in Group T that was higher than 52.0％ (26/50) in Group C (P＜0.05).Conclusions Propofol-remifentanil intravenous anesthesia has definite effects with faster postoperative recovery,less adverse reaction and complications,safety and operablity.
