RESUMO

PURPOSE: Surgical patients are asked to adhere to preoperative fasting guidelines to minimize gastric contents. Large fluid volumes or solid content can still be present as shown with gastric ultrasound. It has been suggested that additional rating of patients' satiety, measured as the feeling of hunger and thirst, could help clinicians to better judge emptying of the stomach. METHODS: We performed a prospective observational study in fasted elective surgical patients. The primary objective was to investigate the correlation between hunger measured on a 0-10 numeric rating scale and total gastric fluid volume measured with gastric ultrasonography. Secondary objectives included the correlation between 1) thirst and total gastric fluid volume and 2) hunger, thirst, and the Perlas grading scale score. RESULTS: We included 515 patients. The exam was inconclusive in 14 individuals (2.7%). The Spearman correlation coefficient between gastric fluid volumes and hunger was 0.11 (95% confidence interval [CI], 0.02 to 0.20) (P = 0.01). The correlation between gastric fluid volumes and thirst was 0.11 (95% CI, 0.02 to 0.20) (P = 0.02). Between antral grades and numeric rating scale, the correlation coefficient was 0.00 (95% CI, -0.09 to 0.09) (P = 1.00) for thirst and 0.00 (95% CI, -0.08 to 0.09) (P = 0.94) for hunger. Ten patients (2.0%) had solid content, 24 presented a grade 2 antrum (4.8%). CONCLUSION: This study suggests that the correlation between total gastric fluid volume and satiety sensation is very weak. Satiety did not reliably predict total gastric fluid volume.

RéSUMé: OBJECTIF: On demande aux patient·es de chirurgie de respecter les directives de jeûne préopératoire afin de minimiser leur contenu gastrique. Comme le montre l'échographie gastrique, de grands volumes de liquide ou des solides peuvent encore être présents. Il a été suggéré qu'une évaluation supplémentaire de la satiété des patient·es, mesurée par la sensation de faim et de soif, pourrait aider les clinicien·nes à mieux estimer la vidange de l'estomac. MéTHODE: Nous avons réalisé une étude observationnelle prospective chez des patient·es de chirurgie non urgente à jeun. L'objectif principal était d'étudier la corrélation entre la faim mesurée sur une échelle d'évaluation numérique de 0 à 10 et le volume total de liquide gastrique mesuré par échographie gastrique. Les objectifs secondaires comprenaient la corrélation entre 1) la soif et le volume total de liquide gastrique et 2) la faim, la soif et le score de l'échelle de classement Perlas. RéSULTATS: Nous avons inclus 515 personnes. L'examen était non concluant chez 14 individus (2,7 %). Le coefficient de corrélation de Spearman entre les volumes de liquide gastrique et la faim était de 0,11 (intervalle de confiance [IC] à 95 %, 0,02 à 0,20) (P = 0,01). La corrélation entre les volumes de liquide gastrique et la soif était de 0,11 (IC 95 %, 0,02 à 0,20) (P = 0,02). Entre les grades antraux et l'échelle d'évaluation numérique, le coefficient de corrélation était de 0,00 (IC 95 %, -0,09 à 0,09) (P = 1,00) pour la soif et de 0,00 (IC 95 %, -0,08 à 0,09) (P = 0,94) pour la faim. Un contenu solide a été observé chez dix personnes (2,0 %), et 24 présentaient un antre de grade 2 (4,8 %). CONCLUSION: Cette étude suggère que la corrélation entre le volume total de liquide gastrique et la sensation de satiété est très faible. La satiété n'a pas permis de prédire de manière fiable le volume total de liquide gastrique. ENREGISTREMENT DE L'éTUDE: clinicaltrials.gov (NCT04884373); enregistrée le 13 mai 2021.

RESUMO

BACKGROUND: Paraplegia is a rare complication of spinal anesthesia. CASE PRESENTATION: We report a case of a 68-year-old man who developed postoperative paraplegia and hypoesthesia after spinal anesthesia for an otherwise uncomplicated transurethral resection of the prostate. Acute transverse myelitis was diagnosed based on urgent MRI. A prior history of similar though less severe neurological symptoms after obinutuzumab treatment for follicular lymphoma suggested a potential causative role for obinutuzumab, a novel monoclonal antibody that has not been associated with such devastating neurological side effects yet. High-dose steroid treatment partially attenuated the symptoms, but debilitating hypoesthesia and motor deficit remained present 3 months postoperatively. CONCLUSION: The presented case warrants caution when performing neuraxial anesthesia in patients on monoclonal antibody therapies.
