RESUMO

PURPOSE: Patients with COVID-19 undergoing hip fracture surgeries have a 30-day mortality of up to 34%. We aimed to evaluate the association between anesthesia technique and 30-day mortality after hip fracture surgery in patients with COVID-19. METHODS: After ethics approval, we performed a retrospective cohort analysis of the American College of Surgeons National Surgical Quality Improvement Program data set from January to December 2021. Inclusion criteria were age ≥ 19 yr, laboratory-confirmed SARS-CoV-2 infection within 14 days preoperatively, and hip fracture surgery under general anesthesia (GA) or spinal anesthesia (SA). Exclusion criteria were American Society of Anesthesiologists Physical Status V, ventilator dependence, international normalized ratio ≥ 1.5, partial thromboplastin time > 35 sec, and platelet count < 80 × 109 L-1. The primary outcome was all-cause 30-day mortality. The adjusted association between anesthetic technique and 30-day mortality was analyzed using multivariable logistic regression. RESULTS: Of 23,045 patients undergoing hip fracture surgery, 331 patients met the study criteria. The median [interquartile range] age was 82 [74-88] yr, and 32.3% were male. The 30-day mortality rate was 10.0% (33/331) for the cohort (10.7%, 29/272 for GA vs 6.8%, 4/59 for SA; P = 0.51; standardized mean difference, 0.138). The use of SA, compared with GA, was not associated with decreased mortality (adjusted odds ratio, 0.61; 95% confidence interval, 0.21 to 1.8; E-value, 2.49). CONCLUSION: Anesthesia technique was not associated with mortality in patients with COVID-19 undergoing hip fracture surgery. The findings were limited by a small sample size.

RéSUMé: OBJECTIF: Les personnes atteintes de COVID-19 bénéficiant d'une chirurgie de fracture de la hanche ont une mortalité à 30 jours allant jusqu'à 34 %. Notre objectif était d'évaluer l'association entre la technique d'anesthésie et la mortalité à 30 jours après une chirurgie de fracture de la hanche chez les personnes atteintes de COVID-19. MéTHODE: Après l'approbation du comité d'éthique, nous avons réalisé une analyse de cohorte rétrospective de l'ensemble de données du Programme national d'amélioration de la qualité chirurgicale de l'American College of Surgeons de janvier à décembre 2021. Les critères d'inclusion étaient un âge ≥ 19 ans, une infection par le SRAS-CoV-2 confirmée en laboratoire dans les 14 jours préopératoires et une chirurgie de fracture de la hanche sous anesthésie générale (AG) ou rachianesthésie (RA). Les critères d'exclusion étaient un statut physique V selon l'American Society of Anesthesiologists, la dépendance à une assistance ventilatoire, un ratio international normalisé ≥ 1,5, un temps de thromboplastine partielle > 35 sec, et une numération plaquettaire < 80 × 109 L−1. Le critère d'évaluation principal était la mortalité à 30 jours toutes causes confondues. L'association ajustée entre la technique anesthésique et la mortalité à 30 jours a été analysée à l'aide d'une régression logistique multivariée. RéSULTATS: Sur 23 045 patient·es opéré·es pour une fracture de la hanche, 331 répondaient aux critères de l'étude. L'âge médian (écart interquartile) était de 82 [74­88] ans et 32,3 % étaient des hommes. Le taux de mortalité à 30 jours était de 10,0 % (33/331) pour la cohorte (10,7 %, 29/272 pour l'AG vs 6,8 %, 4/59 pour la RA; P = 0,51; différence moyenne standardisée, 0,138). L'utilisation de la RA, par rapport à l'AG, n'a pas été associée à une diminution de la mortalité (rapport de cotes ajusté, 0,61; intervalle de confiance à 95 %, 0,21 à 1,8; valeur E, 2,49). CONCLUSION: La technique d'anesthésie n'a pas été associée à la mortalité chez les personnes atteintes de COVID-19 bénéficiant d'une chirurgie de fracture de la hanche. Les résultats ont été limités par la petite taille de l'échantillon. ENREGISTREMENT DE L'éTUDE: www.ClinicalTrials.gov (NCT05133648); enregistrée le 24 novembre 2021.

RESUMO

We have recently shown that visuomotor adaptation following reaches with a misaligned cursor not only induces changes in an individual's motor output, but their proprioceptive sense of hand position as well. Long-term changes are seen in motor adaptation; however, very little is known about the retention of changes in felt hand position. We sought to evaluate whether this recalibration in proprioception, following visuomotor adaptation, is sufficiently robust to be retained the following day (~24 h later), and if so, to determine its extent. Visuomotor adaptation was induced by having subjects perform reaches to visual targets using a cursor representing their unseen hand, which had been gradually rotated 45° counterclockwise. Motor adaptation and proprioceptive recalibration were determined by assessing subjects' reach aftereffects and changes in hand bias, respectively. We found that subjects adapted their reaches and recalibrated their sense of hand position following training with a misaligned cursor, as shown in Cressman and Henriques (J Neurophysiol 102:3505-3518, 2009). More importantly, subjects who showed proprioceptive recalibration in the direction of motor adaptation on Day 1 did retain changes in felt hand position and motor adaptation on Day 2. These findings suggest that in addition to motor changes, individuals are capable of retaining sensory changes in proprioception up to 24 h later.
