The control group received patient-controlled intravenous analgesia, and the observation group received buprenorphine transdermal patch combined with patient-controlled intravenous analgesia. Differences in serum levels of inflammatory factors, oxidative stress indexes and pain mediators of two groups of patients were measured before and 24h after surgery.Results: Differences in serum levels of inflammatory factors, oxidative stress indexes and pain mediators were not statistically significant between the two groups before surgery;24 h after surgery, serum IL-1β, IL-6, IL-8, TNF-α, MDA, SP, PGE2, 5-HT, HA and NPY levels of both groups of patients increased significantly while SOD, TAC and CAT levels decreased significantly, and serum IL-1β, IL-6, IL-8, TNF-α, MDA, SP, PGE2, 5-HT, HA and NPY levels of observation group were lower than those of control group while SOD, TAC and CAT levels were higher than those of control group.Conclusion: Buprenorphine transdermal patch combined with patient-controlled intravenous analgesia can effectively inhibit the expression of pain-related indexes and relieve early postoperative pain intensity in elderly patients with intertrochanteric fracture.展开更多

Methods： Sixty benign prostatic hyperplasia （BPH） patients scheduled for transurethral resection of the prostate （TURP） under general anesthesia with laryngeal mask airway （LMA） were randomly divided into groups F and S. Group F （n=30） received PCIA device with fentanyl 10 ug/kg＋8 mg ondansetron, and Group S （n=30） received placebo （PCIA device with 8 mg ondansetron）. The visual analog scale （VAS） scores for pain were evaluated at 0, 2, 4, 8, 16, 24, and 48 h by the same staff. And recorded were incidence of cystospasm, side effects, application of hemostatic, duration of drawing Foley catheter and continuous bladder irrigation, time of exhaust after operation, time of post-operative stay and cost of hospitalization. Results： The incidence of cystospasm in Group F was significantly lower than that in Group S in the 48 h after operation （P〈0.05）, the VAS scores for pain in Group F was significantly lower than that in Group S within the 48 h after operation （P〈0.01）. The time of exhaust after operation in Group F was significantly later than in Group S （P〈0.05）. No significant difference was observed in applications of hemostatic, duration of drawing Foley catheter, duration of continuous bladder irrigation, time of post-operative stay and cost of hospitalization between the 2 groups. Conclusion： PCIA with fentanyl （10 ug/kg） relieves pain with little side effect and reduces cystospasm satisfactorily.展开更多

Nonetheless, more recently its utility in perioperative setting is being appreciated globally. This review aims to analyse its work beyond its traditional use when employed intravenously in perioperative setting and overall impact on postoperative period. Content: A total of 41 articles were selected for study while 13 of them were chosen for data presentation. Databases such as CENTRAL, MEDLINE/Pubmed, LILACS, Ovid and Scielo were used to search the articles using keywords like Intravenous lidocaine, local anesthetics, perioperative analgesia or postoperative pain. A bolus dose of 1.5 mg/kg and maintenance dose of 2 - 3 mg/kg/h of intravenous lidocaine was used to bring out its analgesic effect and its positive impact on postoperative stage in nearly all the selected studies. Its anti-inflammatory, antinociceptive and immunomodulatory effects were also addressed. Conclusion: Perioperative implication of systemic lidocaine not only lessens pain perception but also assures early return of bowel function, lower incidence of postoperative nausea and vomiting, opioid sparing effect and shorter length of hospital stay. Thus, implementation of lidocaine as a part of perioperative approach should be seriously considered. Its role in surgeries other than abdominal needs more detailed study. In spite of current results encouraging, it may be too early to claim its similar impact in other types of surgeries.展开更多
