ABSTRACT
Objective:To explore the effect of regional nerve block anesthesia for elderly patients with traumatic tibia and fibula fractures.Methods:Ninety-three elderly patients with tibia and fibula fractures undergone surgical treatment were randomly divided into an observation group and a control group, with 47 and 46 patients, respectively, in each group.The control group received general anesthesia and the observation group received a regional nerve block.Results:There was no difference in operative time between the two groups[(42.2±5.4)min and(43.3±5.7)min, t=0.953, P=0.343].The time to recovery of consciousness[(11.2±2.6)min and(14.5±2.8)min, t=5.714, P<0.001]and the volume of intraoperative infusion[(415.6±27.5)ml/L and(686.6±36.3)ml/L, t=40.626, P<0.001]were lower and patients' blood pressure and respiratory rate were also lower at skin incision, fracture fixation, end of surgery and 30 min after surgery in the observation group than in the control group.The levels of Glu, IL-6 and COR were higher than those in the control group(all P<0.05).The incidence of complications was 2.13% in the observation group and 15.22% in the control group( χ2=5.07, P<0.05). Conclusions:Elderly patients with traumatic tibia and fibula fractures receive beneficial anesthetic effects with the regional nerve block technique, with stable hemodynamics, mild stress response and minor adverse reactions.
ABSTRACT
Objective:To investigate the analgesic effects of Dexmedetomidine combined with Ropivacaine for abdominal fascia block(AFB, with transverse abdominis plane block and rectus abdominis sheath block)in elderly patients undergone open surgery for colon cancer.Methods:This was a prospective study.Fifty elderly patients following ASA Ⅰ-Ⅲ open surgery for colon cancer were randomly divided into Group R and Group RD.Patients in Group R were treated with Ropivacaine for AFB, and those in Group RD were given Dexmedetomidine 0.5 μg/kg and Ropivacaine.All patients received Morphine-based patient-controlled intravenous analgesia(PCIA)after surgery.The total dose of postoperative Morphine, the time to first required use of Morphine, and the visual analog score(VAS)at 4, 8, 16, and 24 h after surgery were compared between the two groups.Results:Compared with Group R, patients in Group RD were associated with a significantly decreased total amount of Morphine at 24 h after surgery [25(20-32)mg vs.30(22-38)mg, Z=5.00, P<0.001], a lower VAS at 4 h [17(15-19) vs.36(23-39), Z=23.04, P<0.001]and 8 h after surgery [20(18-22) vs.41(38-55), Z=25.47, P<0.001], a longer time to first required use of Morphine [233(204-256)min vs.183(167-195)min, Z=4.367, P<0.001], and less postoperative nausea and vomiting(20.0% vs.48.0%, P=0.037). Conclusions:For elderly patients after colon cancer surgery, transverse abdominis plane and rectus sheath block with Dexmedetomidine plus Ropivacaine can enhance the analgesic effect, prolong the time of effective analgesia, reduce the amount of Morphine used postoperatively, and is beneficial for early recovery.
ABSTRACT
Objective To investigate the effect of Dexmedetomidine on postoperative impairment of cognitive function in elderly patients undergoing thoracoscopic surgery under wireless analgesia.Methods Eighty elderly patients undergoing thoracoscopic surgery in our hospital from May 2017 to April 2018 were randomly divided into the S group(n=40)receiving Sufentanil under wireless analgesia,and the DS group receiving Dexmedetomidine as add-on to the therapy for S group.The mini-mental state examination(MMSE) score,postoperative pain degree,and serum levels of interleukin(IL)-1,IL-6 and tumor necrosis factor(TNF)-α,as well as adverse reactions were compared between the two groups,preoperatively and postoperatively.Results MMSE score was higher in the DS group than in the S group at 1 and 3 days after operation[(26.85±1.20)vs.(26.33±1.33),(26.65± 1.16)vs.(26.00± 1.29),t =1.795 and 2.370,P =0.038 and 0.010].Pain visual analog scale(VAS)score was lower in the DS group than in the S group at 6 and 12 hours after operation[(4.32±0.64)vs.(4.65±0.77),(4.01±0.45)vs.(4.23±0.59),t=2.138 and 1.875,P=0.018 and 0.032,respectively].At 1 and 3 days after operation,IL-1,IL-6 and TNF-α levels were higher in SD group than in S group (P ＜ 0.05).But,at 5 and 7 days after operation,there was no significant difference in the expression levels of IL-1,IL-6 and TNF between the two groups (P ＞0.05).The incidence of nausea was lower in DS group than in S group(2.5％ vs.15.0％,x2 =3.914,P=0.048),while the incidence of bradycardia was higher in the DS group than in the S group(17.5％ vs.2.5 ％,x2 =5.000,P =0.025).Conclusions Dexmedetomidine not only effectively alleviates the postoperative pain and improves cognitive function in elderly patients undergoing thoracoscopic management under wireless analgesia,but also reduces postoperative inflammatory levels.
ABSTRACT
Objective To investigate the relationship of OPRM1 C354A mutations with the clinical efficacy and toxicity of Morphine in the treatment of cancer pain.Methods We recruited 100 patients with moderate-severe cancer pain treated at our department from January 2016 to December 2016,and divided them into a CA(wild type homozygotes) group,a CG(mutated heterozygotes) group,and a GG (homozygous homozygous) group,according to the allele type of OPRM1 C354A.Regular analgesic doses of Morphine were given to all groups,and VAS scores and adverse reactions at 2,4,8,16,24,aud 48 hours after analgesia were collected and compared among the groups.Results The (OPRM1 C354A mutation groups(CG+GG)had lower VAS scores at every time point,compared with those of the non-mutation group(CA) (2 h:3.61±0.39 vs.4.04±0.52;4 h:3.88±0.41 vs.4.20± 0.15;8 h:3.95±0.32 vs.4.37±0.24;16 h:3.81±0.38 vs.4.33±0.15;24 h:3.84±0.25 vs.4.42± 0.18;and48 h:3.86±0.20 vs.4.41± 0.14) (t=4.648,5.261,7.461,8.454,13.389,and 16.030,respectively,each P=0.000).The incidences of constipation(23.08％ vs.6.25％)and vertigo(25％ vs.8.33％)in the OPRM1 C354A mutation groups(CG+GG)were significantly higher than those in the non-mutation group(CA) (x2 =5.543 and 4.914.P=0.019 and 0.027,respectively).Conclusions Polymorphism of the (PRM1 C354A gene is associated with the clinical efficacy and toxicity of morphine in the treatment of cancer pain.

ABSTRACT
Objective To explore the clinical value of Glucosamine hydrochloride tablets(GH)alone and combination with Xianlinggubao capsules(XLGB)for treatment patients with knee osteoarthritis(KOA).Methods 96 patients with KOA were selected,and were divided into two groups according to the random number method, 48 cases in each group.The control group was treated with GH alone,while the observation group was treated with XL-GB on the basis of the control group.US Western Ontario and McMaster University Osteoarthritis Index (WOMAC) were used to evaluate the symptoms change,including pain,stiffness,physical function scores and total scores before and after treatment.The onset time,knee function (HSS)score at 3 months and 6 months after treatment were recor-ded.CRP and ESR were measured,and the total efficacy was evaluated at the end of treatment.Results The differ-ence of WOMAC score between the two groups was not statistically significant before treatment (P >0.05 ).After treatment,pain,stiffness,physical function scores and total scores were (10.2 ±1.4)points,(3.5 ±1.6)points, (40.5 ±5.0)points and (56.4 ±6.7)points in the observation group,those were (14.8 ±2.6)points,(6.2 ±2.3)points, (52.2 ±6.8)points and (73.3 ±4.5)points in the control group,the differences were statistically significant (t =7.631,4.721,6.791,10.26,all P <0.01).The onset time,HSS score at 3 months and 6 months after treatment in the observation group were (6.0 ±2.2)d,(68.2 ±6.4)points and (84.3 ±6.2)points,while those were (9.8 ± 2.8)d,(58.5 ±3.9)points and (72.8 ±5.4)points in the control group,the differences were statistically significant (t =5.228,6.341,6.852,all P <0.01 ).The improvements of CRP level and ESR in the observation group were more pronounced than those in the control group (t =3.880,2.668,all P <0.05).After treatment,the total effective rate of the observation group was 93.8%(45 /48),while that was 77.1%(37 /48)in the control group,the difference was statistically significant (χ2 =5.352,P <0.05).Conclusion GH combines with XLGB can significantly improve symptoms in patients with KOA,with more rapid recovery of knee function,thus it is a safe and effective therapy.
ABSTRACT
Objective To observe the clinical efficacy and safety of close-loop muscle relaxant injcction system (CLMRIS) combined with auditory evoked potentials index for monitoring in elderly patients during general anesthesia.Methods A total of 100 patients undergong abdominal operation with ASA Ⅰ-Ⅱ anesthesia in our hospital from February 2012 to October 2012 were selected.Patients were randomly divided into 2 groups:the traditional group (n=50) and the CLMRIS group (n=50).The traditional group was anaesthetized according to clinical experience,and the CLMRIS group was used with the muscle relaxant guided by the close-loop muscle relaxant injection system.The auditory evoked potential (AEP) index and the life index were observed,and the dose of muscle relaxant,the time of consciousness recovery,dynamic response rate during operation and the adverse reaction were recorded at the time points at entering the operating room,induction of anesthesia,tracheal intubation,incision,into the abdominal,exploration,closing abdomen,skin suture,consciousness recovery,tracheal extubation,out of room (T0-T10).Results The vital signs in all patients were stable.The dynamic response rate during operation was lower in the CLMRIS group than in the traditional group at each time points of T8-T10 (all P＜0.05).There was no increase in mean artery pressure (MAP) and heart rate in groups at the time points of T0-T1,T8-T10 (all P＞0.05).The time of tracheal intubation,tracheal extubation and consciousness recovery were shorter in the CLMRIS group than in the traditional group [(268±30.4) min vs.(172±23.7) min,(14±6.4) min us.(18±7.9) min,(8.8±2.9) min vs.(12.2±4.6) min,respectively,t=3.277,6.341,3.346,all P＜0.05].There were no significant differences in AEP index between groups at the time of T0 (P＞0.05),but at the time of T1,the AEP index was lower in CLMRIS group than in the traditional group (P＜0.05).Conclusions The application of close loop muscle relaxant injection system can improve the safety of general anesthesia in the elderly and reduce the incidence of postoperative residual paralysis.The CLMRIS combined with the auditory evoked potential for monitoring depth of anesthesia can prevent and reduce the incidence of intraoperative awareness,has a strong controllability in general anesthesia with smooth induction,and can reduce the dose of anesthetic drugs to achieve the best anesthetic effect.
