Efficacy of Dexmedetomidine as an Adjuvant to Local Anesthetic Agent in Scalp Block and Scalp Infiltration to Control Postcraniotomy Pain: A Double-Blind Randomized Trial.

ABSTRACT: Context:Scalp infiltration and scalp block are being used to manage postcraniotomy pain. Dexmedetomidine has been successfully used as an adjuvant in regional anesthesia. The study was intended to compare whether addition of dexmedetomidine prolonged the duration of analgesia as well as to compare the two techniques. Aims:The primary objective was to assess whether addition of dexmedetomidine to bupivacaine prolonged the duration of analgesia. The secondary objective was to compare between scalp nerve block and scalp infiltration as techniques for pain relief. Settings and Design:The randomized control study was conducted in a tertiary care center from November 2013 to October 2014. Materials and Methods:A total of 150 American Society of Anesthesiologists Physical Status I-II patients, aged 18-70 years undergoing elective craniotomy were included. Patients were randomized into three groups of 50 patients, i.e., Group BI (bupivacaine infiltration), Group BDI (bupivacaine and dexmedetomidine infiltration), and Group BDNB (bupivacaine and dexmedetomidine scalp nerve block). Patient's pain score, pain-free interval, rescue analgesic requirement, and hemodynamic and respiratory parameters were noted for 48 h. Patients were followed up at 1 and 3 months to assess postcraniotomy pain. Results:Pain-free period was significantly longer in Group BDNB than Groups BDI and BI (P < 0.0001) and pain control was better in dexmedetomidine containing groups than in bupivacaine group (BI) (P < 0.0001). The rescue analgesic requirement was significantly lower in Group BDNB and Group BDI compared to Group BI. Conclusion:The addition of dexmedetomidine (1 ?g/kg) to bupivacaine prolonged the pain-free period. Scalp nerve block is a superior technique than scalp infiltration.

Project description:BACKGROUND:Perineural dexamethasone has been shown to prolong the duration of local anesthetic (LA) effect in regional anesthesia; however, the use of perineural dexamethasone as an adjuvant to to the transversus abdominis plane (TAP) block remains controversial. This meta-analysis sought to assess the efficacy of dexamethasone in prolonging the TAP block and enhancing recovery after abdominal surgery. METHODS:We identified and analyzed 9 RCTs published on or before September 30, 2017, regardless of the original language, after searching the following 6 bibliographic databases: PubMed, EMBASE, Medline, Springer, Ovid, and the Cochrane Library. databases. These studies compared the effects of perineural dexamethasone mixed with local anesthetic versus local anesthetic alone in the TAP block. The Cochrane Collaboration's Risk of Bias Tool was used to evaluate the methodological quality of each RCT. The primary outcomes were the time until the first request for postoperative analgesics and the analog pain scores at 2, 6, 12, and 24 h after surgery. The secondary outcomes were the analgesic consumption and the incidence of nausea and vomiting on the first day after surgery. We used Trial Sequential Analysis (TSA) to control for random errors. RESULTS:Perineural dexamethasone prolonged the duration of LA effect in the TAP block [mean difference (MD): 2.98 h; 95% confidence interval (CI): 2.19 to 3.78] and reduced analog pain scores at 2 h [MD: -1.15; 95% CI: -2.14 to -0.16], 6 h [MD: -0.97; 95% CI: -1.51 to -0.44], and 12 h [MD: -0.93; 95% CI: -1.14 to -0.72] postoperatively. Furthermore, the use of perineural dexamethasone was associated with less analgesic consumption [standard mean difference: -1.29; 95% CI: -1.88 to -0.70] and a lower incidence of nausea and vomiting [odds ratio: 0.28; 95% CI: 0.16 to 0.49] on the first day after surgery. CONCLUSION:Dexamethasone prolongs the LA effect when used as an adjuvant in the TAP block and improves the analgesic effects of the block.
