ABSTRACT Patients undergoing abdominal hysterectomy often have significant postoperative pain despite the use of concurrent multimodal pain strategies. Neuraxial anesthesia has opioid-sparing effects and may provide better postoperative recovery to patients when compared with general anesthesia. Our main objective in this study was to compare the effects of neuraxial and general anesthesia on postoperative quality of recovery after abdominal hysterectomy.
The study was a prospective, randomized, controlled clinical trial. Seventy healthy females were recruited and randomized to a general anesthesia or neuraxial technique as their primary anesthetic regimen. The primary outcome was the global quality of recovery-40 questionnaire (QoR-40) at 24 hours after the surgical procedure. Other data collected included postoperative pain scores and opioid consumption. Data were analyzed using the Mann-Whitney U test, Fisher's exact test, and linear regression. A P value <0.05 was considered statistically significant.
The median difference (95% confidence interval [CI]) in the global QoR-40 score at 24 hours between the neuraxial and general anesthesia groups was 17 (11 to 21.5) (P < 0.001). Patients in the neuraxial anesthesia group had better quality of recovery scores in all the QoR-40 subcomponents than did the general anesthesia group (all P < 0.005). The median difference in global QoR-40 scores at 48 hours between the neuraxial anesthesia and the general anesthesia groups was 8 (6-10) (P < 0.001). Postoperative opioid consumption and pain scores were higher in the general anesthesia group than in the neuraxial anesthesia group. There was an inverse linear relationship between opioid consumption and postoperative quality of recovery at 24 hours, r(2) = 0.67 (P < 0.0001, 95% CI of 0.77 to 0.51), and at 48 hours, r(2) = 0.58 (P < 0.0001, 95% CI of 0.72 to 0.42).
Neuraxial anesthesia provides better quality of recovery than does general anesthesia for patients undergoing abdominal hysterectomy. The opioid-sparing effects of neuraxial anesthesia were associated with a better quality of recovery in patients after the surgical procedure. In the absence of contraindications, neuraxial anesthesia seems to be a better anesthetic plan for those patients.

    ABSTRACT: Summary The development of analgesic interventions in paediatric surgical patients is often limited by the inherent difficulties of conducting large randomized clinical trials to test interventions in those patients. Regional anaesthesia is a valid strategy to improve postoperative pain in the adult surgical population, but the effects of regional anaesthesia on postoperative pain outcomes in paediatric patients are currently not well defined. The main objective of the current review was to systematically evaluate the use of regional anaesthesia techniques to minimize postoperative pain in paediatric patients. A systematic search was performed to identify randomized controlled trials that evaluated the effects of the regional anaesthesia techniques on postoperative pain outcomes in paediatric surgical patients' procedures. Seventy-three studies on 5125 paediatric patients were evaluated. Only few surgical procedures had more than one small randomized controlled trial favouring the use of regional anaesthesia to minimize postoperative pain (ophthalmological surgery, cleft lip repair, inguinal hernia, and urological procedures). Additional evidence is required to support the use of specific regional anaesthesia techniques to improve postoperative pain for several surgical procedures (craniectomy, adenotonsillectomy, appendectomy, cardiac surgery, umbilical hernia repair, upper and lower extremity) in paediatric patients. Currently, only a very limited number of regional anaesthesia techniques have demonstrated significant improvement on postoperative pain outcomes for a restricted number of surgical procedures. More studies are needed in order to establish regional anaesthesia as a valid strategy to improve analgesia in the paediatric surgical population.

    ABSTRACT: Background. The overall effect of perineural dexamethasone on postoperative analgesia outcomes has yet to be quantified. The main objective of this quantitative review was to evaluate the effect of perineural dexamethasone as a nerve block adjunct on postoperative analgesia outcomes. Methods. A systematic search was performed to identify randomized controlled trials that evaluated the effects of perineural dexamethasone as a block adjunct on postoperative pain outcomes in patients receiving regional anesthesia. Meta-analysis was performed using a random-effect model. Results. Nine randomized trials with 760 subjects were included. The weighted mean difference (99% CI) of the combined effects favored perineural dexamethasone over control for analgesia duration, 473 (264 to 682) minutes, and motor block duration, 500 (154 to 846) minutes. Postoperative opioid consumption was also reduced in the perineural dexamethasone group compared to control, -8.5 (-12.3 to -4.6) mg of IV morphine equivalents. No significant neurological symptoms could have been attributed to the use of perineural dexamethasone. Conclusions. Perineural dexamethasone improves postoperative pain outcomes when given as an adjunct to brachial plexus blocks. There were no reports of persistent nerve injury attributed to perineural administration of the drug.

    ABSTRACT: This article reviews the current evidence for multimodal analgesic options for common surgical procedures. As perioperative physicians, we have come a long way from using only opioids for postoperative pain to combinations of acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), selective Cyclo-oxygenase (COX-2) inhibitors, local anesthetics, N-methyl-d-aspartate (NMDA) receptor antagonists, and regional anesthetics. As discussed in this article, many of these agents have decreased narcotic requirements, improved patient satisfaction, and decreased postanesthesia care unit (PACU) times, as well as morbidity in the perioperative period.
