Daily Anesthesiology Research Analysis

In this single-centre, three-arm randomized trial of 320 patients, laparoscopic bilateral dual transversus abdominis plane block significantly improved the 24-hour Quality of Recovery-15 score compared with intravenous patient-controlled analgesia alone. Surgical rectus sheath block did not demonstrate superiority, although both regional techniques substantially prolonged the time to first rescue analgesia without block-related complications.

Impact: The study directly compares two pragmatic regional analgesia strategies using a patient-centered recovery endpoint and provides a clinically actionable positive result for laparoscopic dual TAP block. Its negative finding for surgical rectus sheath block also helps prevent adoption of an apparently plausible but insufficiently supported technique.

Clinical Implications: For selected patients undergoing minimally invasive colorectal surgery, laparoscopic bilateral dual TAP block may be incorporated into multimodal analgesia to improve early postoperative recovery and delay rescue analgesic use. The technique should complement, rather than automatically replace, other analgesic components because opioid consumption and length of stay were not significantly reduced.

Future Directions: Multicentre trials should confirm the recovery benefit of BD-TAP block, assess cost-effectiveness and procedure-related learning curves, and determine whether it improves clinically important outcomes such as opioid-related adverse events, discharge readiness, and patient-reported function.

In the iHOPE pragmatic multicentre randomized trial, the 30-day composite of death or new serious cardiac or pulmonary complications occurred in 14% of patients receiving spinal anesthesia and 12% receiving general anesthesia. The difference was not statistically significant, supporting an individualized anesthetic approach rather than a routine assumption that spinal anesthesia is superior for older adults with hip fracture.

Impact: This large pragmatic trial addresses a common and consequential anesthetic decision in frail older adults and provides important negative evidence against assuming a clinically meaningful advantage of spinal anesthesia. The findings can support shared decision-making and reduce technique-driven practice variation.

Clinical Implications: Clinicians should select spinal or general anesthesia according to patient characteristics, contraindications, surgical circumstances, expertise, and preferences rather than expecting spinal anesthesia to universally reduce serious complications. The results do not establish equivalence conclusively because the trial stopped early and had substantial crossover.

Future Directions: Further adequately powered pragmatic trials or individual-participant meta-analyses should examine clinically important subgroups, including patients with frailty, cardiopulmonary disease, cognitive impairment, or specific fracture and surgical characteristics.

This updated meta-analysis included 79 randomized trials involving 9340 patients and found no statistically significant reduction in overall mortality with remote ischemic preconditioning. Mortality was lower in the subgroup receiving the intervention before anesthesia induction, while exploratory analyses suggested reductions in stroke, hospital stay, and postoperative neutrophil gelatinase-associated lipocalin, supporting targeted rather than indiscriminate further investigation.

Impact: The analysis is important because it tempers enthusiasm for a biologically attractive organ-protection strategy by demonstrating a neutral overall mortality result while identifying a clinically testable timing signal. It also illustrates the value of negative and subgroup findings for designing more informative future trials.

Clinical Implications: Routine remote ischemic preconditioning cannot currently be recommended solely to reduce mortality in noncardiac surgery. If studied clinically, it should be evaluated with standardized application before anesthesia induction and with prespecified patient-centered outcomes, while considering the heterogeneity and risk of bias of existing trials.

Future Directions: Future trials should preregister standardized pre-induction RIPC protocols, enrich enrollment for patients at meaningful risk of organ injury, use sham controls where feasible, and prioritize mortality, stroke, kidney injury, and patient-centered recovery outcomes with adequate long-term follow-up.
