A Case Report of Pulmonary Embolectomy Under Cardiopulmonary Bypass in a Patient with Intracranial Hemorrhage and History of Heparin-Induced Thrombocytopenia.

Pulmonary embolism is a common complication after intracranial hemorrhage. As thrombolysis is contraindicated in this situation, surgical pulmonary embolectomy may be indicated in case of high-risk pulmonary embolism but requires transient anticoagulation with heparin during cardiopulmonary bypass. We report the case of a patient with a history of heparin-induced thrombocytopenia who presented with a high-risk pulmonary embolism 10 days after the spontaneous onset of a voluminous intracerebral hematoma. Despite high doses of heparin required to run the cardiopulmonary bypass and subsequent anticoagulation by danaparoid sodium, the brain hematoma remained stable and the patient was discharged without complications 30 days after surgery.

Sufentanil sublingual tablet system for enhanced recovery after total knee arthroplasty: a prospective observational case study.

BACKGROUND: Postoperative pain is one of the main factors that delays recovery after prosthetic knee surgery. The use of sufentanil sublingual tablet systems (SSTS) can effectively relieve postoperative pain, but their value in facilitating early mobilization has been little studied so far. Our aim here was to assess whether their use could facilitate recovery after knee arthroplasty in an enhanced recovery program. CASE PRESENTATION: In a prospective observational single-center study, thirty patients operated on for primary knee arthroplasty in the enhanced recovery pathway were included. Patients who received the SSTS (n=15) were compared with those who received an intravenous morphine patient-controlled analgesia (PCA) (n=15). Our recovery program included in particular the use of an adductor canal block, periarticular infiltration of local anesthetic by the surgeon, removal of the venous cannula from the recovery room if possible, the use of an SSTS when available or an IV morphine PCA otherwise, and early physiotherapy. Recovery parameters including the Timed-Up and Go test, pain scores at rest and on exertion, knee flexions, complications, and lengths of hospital stay were not significantly different between the two groups. However, the postoperative opioid consumption in morphine equivalents was significantly greater in the SL-sufentanil group and these patients had their venous cannula removed earlier than in IV-morphine group. CONCLUSION: In our center, the use of a SSTS was suitable for treating postoperative pain after knee arthroplasty, but it did not improve early recovery in comparison with a morphine PCA.

Risk Factors and Consequences of Late-Onset Hyperlactatemia After Cardiac Surgery With Cardiopulmonary Bypass: A Single-Center Retrospective Study.

OBJECTIVE: Mechanisms and consequences of late-onset hyperlactatemia after cardiac surgery remain unclear. The aim of this study was to identify risk factors and outcomes of late hyperlactatemia, defined as a lactate value ≥3 mmol/L developing in the intensive care unit (ICU) after not being elevated on admission after cardiac surgery with cardiopulmonary bypass. DESIGN: A retrospective analysis of prospectively collected data. SETTING: A single-center University Hospital. PARTICIPANTS: Patients who underwent elective cardiac surgery with cardiopulmonary bypass in 2019 and who had normal lactatemia at ICU admission. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patients were divided in 2 groups according to their lactatemia on postoperative day 1 (14.0 ± 3.0 hours after ICU admission): normal lactatemia (control group) and late hyperlactatemia (HL group). Risk factors for late hyperlactatemia were identified using a multivariate analysis, and postoperative outcomes were compared using a composite criterion of severe outcomes. Of the 432 included patients, 37 (8.5%) presented with late hyperlactatemia. Risk factors independently associated with hyperlactatemia were afternoon surgery (odds ratio [OR] 4.24, 95% CI 2.00-9.35), a bleeding >300 mL within the 6 hours after surgery (H6) (OR 3.77, 95% CI 1.71-8.30), and H6 fluid loading >250 mL (OR 2.64, 95% CI 1.22-5.55). Patients with hyperlactatemia presented more frequently with major postoperative complications, including acute kidney injury, and received more frequent red-cell transfusion. CONCLUSION: The strongest risk factors associated with late-onset hyperlactatemia in the authors' population were afternoon surgery and H6 bleeding >300 mL. Poor postoperative outcomes were more frequent in patients with late hyperlactatemia, even in the absence of early hyperlactatemia or severe obvious condition.
