ABSTRACT
Objective:To evaluate the effect of intravenous infusion of lidocaine on the efficacy of conventional treatment for rheumatoid arthritis.Methods:Forty-four patients with rheumatoid arthritis of either sex, aged 32-85 yr, weighing 40-76 kg, who were admitted to the Department of Pain and Nephrology in our hospital from September 2019 to September 2020, were divided into 2 groups ( n=22 each) according to the random number table method: control group (C group) and lidocaine group (L group). Both groups received conventional treatment.When visual analogue scale (VAS) score ≥5, glucocorticoid (GC) and non-steroidal anti-inflammatory drugs (NSAIDs) were taken orally to maintain the VAS score ≤4.In group L, 0.2% lidocaine hydrochloride injection 3 mg/kg (diluted with 0.9% sodium chloride injection 500 ml) was intravenously infused at a rate of 25 ml/h for 2 h, once a day, for 5 consecutive days, based on the conventional treatment.The VAS score, 28-joint Disease Activity Score (DAS28 score), simplified disease activity index score (SDAI score), consumption of GC and NSAIDs and adverse reactions were recorded before treatment (T 1) and at 1, 4 and 8 weeks after treatment (T 2-4). The temperature of the pain area of the affected joint was evaluated through infrared thermal imaging at T 1 and T 2. Results:Compared with the baseline at T 1, VAS score, DAS28 score and SDAI score were significantly decreased at each time point, and the temperature of the pain area of the affected joint at T 2 was decreased in the two groups ( P<0.05). There were no significant differences in VAS score, DAS28 score and SDAI score at each time point between two groups ( P>0.05). Compared with group C, the consumption of GC and NSAIDs was significantly decreased, and the temperature of the pain area of the dorsum of both hands and the dorsum of right foot at T 2 and incidence of adverse reactions were decreased in group L ( P<0.05). Conclusions:Intravenous infusion of lidocaine can optimize the efficacy of conventional treatment for rheumatoid arthritis.
ABSTRACT
Objective To investigate the effect of continual care on postoperative medication compliance of patients with osteoporotic vertebral compression fractures (OVCF) after vertebroplasty.Methods A retrospective case control study was performed to analyze the clinical data of 150 patients with OVCF who underwent vertebroplasty in Guizhou People's Hospital from January 2016 to May 2017.There were 38 males and 112 females,aged 47-88 years,with an average of 67.5 years.Seventy-five patients were given continual care such as telephone follow-up and home visit (continual care group).Seventy-five patients were given routine health education (routine care group) when they were discharged from hospital.Visual analogue scale (VAS) and Oswestry dysfunction index (ODI) before operation,1 day,1,3,6 and 12 months after operation,as well as medication compliance and vertebral re-fracture at 1,3,6 and 12 months after operation were compared between the two groups.Results The preoperative VAS of the routine care group was 6 (6-7),1 (0-1),1 (1-3),2 (1-3) and 3 (2-5) points at 1 day and 1,3,6 and 12 months after operation,respectively.The preoperative ODI was 21 (18-27),0 (0-0),2 (1-4),5 (3-7),7 (5-10),10 (7-14) points at 1 day,1,3,6 and 12 months after operation.In the continual care group,VAS was 7 (6-7) points before operation,0 (0-1),1 (0-1),1 (0-2) and 2 (1-3) points at 1 day,1,3,6 and 12 months after operation,respectively.ODI of the continual care group was 18 (22-28) points before operation,0 (0-1),2 (0-4),4 (1-5),4 (3-6) and 6 (4-9) at 1 day,1,3,6 and 12 months after operation.The VAS and ODI of the two groups were lower than those before operation,and the scores of the continual care group were lower than those of the routine care group at 1,3,6 and 12 months after operation (P ＜ 0.05).The medication compliance rates of continual care group were 93％,89％,91％ and 84％ at 1,3,6 and 12 months after operation,while those of routine care group were 44％,40％,47％ and 40％ respectively (P ＜0.05).The incidence of vertebral re-fracture was 1％,1％,3％ and 3％ in continual care group and 3％,5％,5％ and 7％ in routine care group at 1,3,6 and 12 months after operation respectively (P ＜ 0.05).Conclusion Continual care can improve the medication compliance of OVCF patients after treatment with vertebroplasty,relieve pain,improve the quality of life,and reduce the incidence of vertebral re-fracture,which is worthy of clinical promotion.
ABSTRACT
Objective To investigate the role of NMDA receptors in central medial thalamus (CMT) in the unconscious?ness induced by general anesthesia. Methods A total of 60 rat models for microinfusion were assigned into 4 groups (n=15 for each group). After induction with propofol, 10 mmol/L (NMDA10 group), 20 mmol/L (NMDA 20 group) and 40 mmol/L (NMDA40 group) of NMDA and normal saline (group C) with equal volume were microinfused into CMT. The incidence of purposeful movement and recovery time of righting reflex were observed in each group respectively. Infusion sites were local?ized by histological method. Results When the microinfusion site localized within CMT, comparing with group C, the recov?ery time of righting reflex reduced notably in three NMDA groups (P0.05). Conclusion Microinfusion of NMDA agonist into CMT reverses propofol anesthesia, indicating that NMDA receptor in CMT may contribute to the propofol-induced unconsciousness.
