Abstract

Purpose: While intra-abdominal hypertension (IAH) has been associated with adverse outcomes in multiple settings, the epidemiology and clinical implications of IAH in the context of cardiac surgery are less known. In this study, we aimed to describe the prevalence of IAH in patients undergoing cardiac surgery and determine its association with patient characteristics and postoperative outcomes.

Methods: We conducted a single-centre prospective cohort study in which intra-abdominal pressure was measured in the operating room after general anesthesia (T1), after the surgical procedure (T2), and two hours after intensive care unit (ICU) admission (T3) in a subset of patients. Intra-abdominal hypertension was defined as intra-abdominal pressure (IAP) ≥ 12 mm Hg. Postoperative outcomes included death, acute kidney injury (AKI), and length of stay in the ICU and hospital.

Results: A total of 513 IAP measurements were obtained from 191 participants in the operating room and 131 participants in the ICU. Intra-abdominal hypertension was present in 105/191 (55%) at T1, 115/191 (60%) at T2, and 31/131 (24%) at T3. Intra-abdominal pressure was independently associated with body mass index, central venous pressure, and mean pulmonary artery pressure but was not associated with cumulative fluid balance. Intraoperative IAH was not associated with adverse outcomes including AKI.

Conclusions: Intra-abdominal hypertension is very common during cardiac surgery but its clinical implications are uncertain.

RéSUMé: OBJECTIF: Bien que l’hypertension intra-abdominale (HIA) ait été associée à des issues indésirables dans de multiples contextes, l’épidémiologie et les implications cliniques de l’HIA dans le contexte de la chirurgie cardiaque sont moins connues. Dans cette étude, nous avons cherché à décrire la prévalence de l’HIA chez les patients bénéficiant d’une chirurgie cardiaque et à déterminer son association avec les caractéristiques des patients et les issues postopératoires. MéTHODE: Nous avons mené une étude de cohorte prospective monocentrique dans laquelle la pression intra-abdominale a été mesurée en salle d’opération après une anesthésie générale (T1), après l’intervention chirurgicale (T2) et deux heures après l’admission à l’unité de soins intensifs (USI) (T3) dans un sous-ensemble de patients. L’hypertension intra-abdominale a été définie comme une pression intra-abdominale (PIA) ≥ 12 mmHg. Les issues postopératoires comprenaient le décès, l’insuffisance rénale aiguë (IRA), et la durée du séjour à l’USI et à l’hôpital. RéSULTATS: Au total, 513 mesures de la PIA ont été obtenues auprès de 191 participants en salle d’opération et de 131 participants à l’USI. L’hypertension intra-abdominale était présente chez 105/191 patients (55 %) à T1, 115/191 (60 %) à T2 et 31/131 (24 %) à T3. La pression intra-abdominale était indépendamment associée à l’indice de masse corporelle, à la pression veineuse centrale et à la pression artérielle pulmonaire moyenne, mais n’était pas associée à un bilan hydrique cumulatif. L’HIA peropératoire n’était pas associée à des issues indésirables, y compris à l’IRA. CONCLUSION: L’hypertension intra-abdominale est très fréquente lors d’une chirurgie cardiaque, mais ses implications cliniques sont incertaines.
