Ambulatory total hip and knee arthroplasty: a literature review and perioperative considerations.

PURPOSE: Total joint arthroplasty (TJA), particularly for the hip and knee, is one of the most commonly performed surgical procedures. The advancement/evolution of surgical and anesthesia techniques have allowed TJA to be performed on an ambulatory/same-day discharge basis. In this Continuing Professional Development module, we synthesize the perioperative evidence that may aid the development of successful ambulatory TJA pathways. SOURCE: We searched MEDLINE, Embase, CENTRAL, and the Cochrane Database of Systematic Reviews for ambulatory or fast-track TJA articles. In the absence of direct evidence for the ambulatory setting, we extrapolated the evidence from the in-patient TJA literature. PRINCIPAL FINDINGS: Patient selection encompassing patient, medical, and social factors is fundamental for successful same-day discharge of patients following TJA. Evidence for the type of intraoperative anesthesia favours neuraxial technique for achieving same day discharge criteria and reduced perioperative complications. Availability of short-acting local anesthetic for neuraxial anesthesia would affect the anesthetic choice. Nonetheless, modern general anesthesia with multimodal analgesia and antithrombotics in a well selected population can be considered. Regional analgesia forms an integral part of the multimodal analgesia regime to reduce opioid consumption and facilitate same-day hospital discharge, reducing hospital readmission. For ambulatory total knee arthroplasty, a combination of adductor canal block with local anesthetic periarticular infiltration provided is a suitable regional analgesic regimen. CONCLUSION: Anesthesia for TJA has evolved as such that same-day discharge will become the norm for selected patients. It is essential to establish pathways for early discharge to prevent adverse effects and readmission in this population. As more data are generated from an increased volume of ambulatory TJA, more robust evidence will emerge for the ideal anesthetic components to optimize outcomes.

RéSUMé: OBJECTIF: L'arthroplastie par prothèse totale (APT), en particulier de la hanche et du genou, constitue l'une des interventions chirurgicales les plus couramment pratiquées. L'avancement et l'évolution des techniques chirurgicales et d'anesthésie ont permis de réaliser une APT en ambulatoire/sur la base d'un congé le jour même. Dans ce module de développement professionnel continu, nous proposons une synthèse des données probantes périopératoires qui pourraient contribuer à l'élaboration de trajectoires réussies pour l'APT en ambulatoire. SOURCES: Nous avons réalisé des recherches dans MEDLINE, Embase, CENTRAL et dans la base de données Cochrane des revues systématiques à la recherche d'articles sur les APT ambulatoires ou accélérées. En l'absence de données probantes directes dans un contexte ambulatoire, nous avons extrapolé les données probantes à partir de la littérature sur les APT en milieu hospitalier. CONSTATATIONS PRINCIPALES: La sélection des patient·es englobant les facteurs patient·es, médicaux et sociaux est fondamentale pour un congé réussi le jour même après une APT. Les données probantes portant sur le type d'anesthésie peropératoire privilégient la technique neuraxiale pour respecter les critères de congé le jour même et réduire les complications périopératoires. La disponibilité d'un anesthésique local à courte durée d'action pour l'anesthésie neuraxiale affecterait le choix de l'anesthésique. Néanmoins, dans une population bien sélectionnée, l'anesthésie générale moderne avec analgésie multimodale et antithrombotiques peut être envisagée. L'analgésie régionale fait partie intégrante d'un régime d'analgésie multimodale visant à réduire la consommation d'opioïdes et à faciliter le congé de l'hôpital le jour même, ce qui réduit le nombre de réadmissions. En ce qui concerne l'arthroplastie totale du genou en ambulatoire, la combinaison d'un bloc du canal des adducteurs et d'une infiltration périarticulaire d'anesthésique local constitue un régime approprié d'analgésie régionale. CONCLUSION: L'anesthésie pour les APT a évolué de telle sorte que le congé le jour même deviendra la norme pour certain·es patient·es. Il est essentiel d'établir des trajectoires de congé précoce afin de prévenir les effets indésirables et la réadmission dans cette population. Au fur et à mesure que davantage de données seront générées à partir d'un volume accru d'APT en ambulatoire, des données probantes plus solides émergeront pour appuyer les composantes idéales de l'anesthésie pour optimiser les devenirs.

Research priorities in regional anaesthesia: an international Delphi study.

BACKGROUND: Regional anaesthesia use is growing worldwide, and there is an increasing emphasis on research in regional anaesthesia to improve patient outcomes. However, priorities for future study remain unclear. We therefore conducted an international research prioritisation exercise, setting the agenda for future investigators and funding bodies. METHODS: We invited members of specialist regional anaesthesia societies from six continents to propose research questions that they felt were unanswered. These were consolidated into representative indicative questions, and a literature review was undertaken to determine if any indicative questions were already answered by published work. Unanswered indicative questions entered a three-round modified Delphi process, whereby 29 experts in regional anaesthesia (representing all participating specialist societies) rated each indicative question for inclusion on a final high priority shortlist. If ≥75% of participants rated an indicative question as 'definitely' include in any round, it was accepted. Indicative questions rated as 'definitely' or 'probably' by <50% of participants in any round were excluded. Retained indicative questions were further ranked based on the rating score in the final Delphi round. The final research priorities were ratified by the Delphi expert group. RESULTS: There were 1318 responses from 516 people in the initial survey, from which 71 indicative questions were formed, of which 68 entered the modified Delphi process. Eleven 'highest priority' research questions were short listed, covering themes of pain management; training and assessment; clinical practice and efficacy; technology and equipment. CONCLUSIONS: We prioritised unanswered research questions in regional anaesthesia. These will inform a coordinated global research strategy for regional anaesthesia and direct investigators to address high-priority areas.

Factors influencing the choice of anesthetic technique for primary hip and knee arthroplasty.

Despite evidence in the literature, continuing wide variation exists in anesthetic technique for primary joint arthroplasties. Recent evidence suggests that neuraxial anesthesia has advantages over general anesthesia in terms of mortality, major morbidity and healthcare utilization. Yet, despite the proposed benefits, utilization of these two techniques varies greatly across geographical locations, with general anesthesia being most common for total hip arthroplasty (THA) and total knee arthroplasty (TKA) in parts of the world. We uncover some factors that promote or hinder the use of neuraxial anesthesia in THA and TKA. Healthcare professionals should be familiarized with the evidence for neuraxial anesthesia, and unbiased educational material should be developed for patients regarding anesthetic options for THA and TKA in order to promote best practice.
