Local and regional anesthesia

Background: Adequate pain control is difficult to achieve in patients with multiple rib fractures (MRF). Serratus plane block (SPB) is a novel technique for alleviating rib fracture pain. Several published case reports support this hypothesis. ⋯ Conclusion: SPB improves pain scores and IS volumes in MRF. Because it is not limited by patient positioning or anticoagulation and has a better safety profile, it may offer a viable alternative to neuraxial techniques. Additional studies are necessary to evaluate its efficacy compared to neuraxial techniques.

The purpose of this study was to determine if the standardization of using liposomal bupivacaine in transversus abdominis plane (LB TAP) blocks eliminated the benefit of intrathecal morphine (ITM) in patients after undergoing a cesarean section. ⋯ Patients who received ITM in addition to an LB TAP block received less opioids in the first 24 hours and overall when compared to those who received an LB TAP alone. This suggests that ITM still plays a role in providing analgesia to patients who have also received an LB TAP block as a part of their multimodal pain regimen for cesarean sections.

Postoperative cognitive dysfunction has gained much attention over the last years. Multiple clinical trials have attempted to differentiate the effect of local vs general anesthesia on postoperative cognitive function. The aim of this work was to study the effect of local anesthesia with lidocaine vs bupivacaine on cognitive function. ⋯ Both lidocaine and bupivacaine caused postoperative cognitive impairment. Lidocaine was found to have a worse effect on cognitive function than bupivacaine, but the difference was not statistically significant.

Regional anesthesia is becoming increasingly popular among anesthesiologists in the management of postoperative analgesia following pediatric surgery. The main objective of this review was to systematically evaluate the last 5 years of randomized controlled trials on the role of regional anesthesia techniques in alleviating postoperative pain associated with various pediatric surgical procedures. Forty studies on 2,408 pediatric patients were evaluated. ⋯ Only a few surgical procedures (cholecystectomy, inguinal hernia repair, and non-laparoscopic major abdominal surgery) reported no significant difference in the postoperative pain relief compared with the standard anesthetic management. The growing number of randomized controlled trials in the pediatric literature is very promising; however, additional confirmation is needed to reinforce the use of specific regional anesthesia techniques to provide optimal postoperative pain relief for a few surgical procedures (reconstructive ear surgery, chest wall deformity, hypospadias, umbilical hernia, cleft palate repair) in pediatric patients. More randomized controlled trials are needed to establish regional anesthesia as an essential component of postoperative analgesia management in children.

Frailty is a state of decreased physiologic reserve and resistance to stressors. Its prevalence increases with age and is estimated to be 26% in those aged above 85 years. As the population ages, frailty will be increasingly seen in surgical patients receiving anesthesia. ⋯ This review also considers how frailty, with its decline of organ function, affects the metabolism of anesthetic agents and may influence the choice of anesthetic technique in an older person. Optimal perioperative care includes the identification of frailty, a multisystem and multidisciplinary evaluation preoperatively, and discussion of treatment goals and expectations. We conclude with an overview of the emerging evidence that Comprehensive Geriatric Assessment can improve postoperative outcomes and a discussion of the models of care that have been developed to improve preoperative assessment and enhance the postoperative recovery of older surgical patients.
