Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.
SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.
Patient: Female, 71Final Diagnosis: Rupture of a pancreaticoduodenal artery aneurysmSymptoms: —Medication: —Clinical Procedure: Surgical operationSpecialty: SurgeryObjective:Rare diseaseBackground:Ruptured aneurysms of the pancreaticoduodenal artery result in fatal hemorrhage and high mortality. Therefore, prompt diagnosis and treatment are required, but there are sometimes problems differentiating this specific diagnosis from other abdominal pathologies.Case Report:We encountered a rare case of a ruptured pancreaticoduodenal artery aneurysm with an atypical clinical presentation that simulated acute pancreatitis. A 71-year-old woman was admitted to the emergency department with abdominal pain in the left upper quadrant, a slightly elevated level of pancreatic amylase, and cholelithiasis on ultrasonography. With persistent pain and progressively decreasing hemoglobin level, computed tomography with contrast showed fluid collection in the subphrenic space, a retroperitoneal hematoma, and a pancreaticoduodenal artery aneurysm that appeared to originate from a branch of the SMA. Urgent angiography indicated spontaneous rupture of a pancreaticoduodenal artery aneurysm. Emergent surgery was undertaken, and a simple aneurysmectomy was successfully performed. The patient’s recovery was unremarkable. The prompt diagnosis of a pancreaticoduodenal artery aneurysm was difficult because the initial symptoms were vague and misleading in our case.Conclusions:A high level of suspicion, rapid diagnostic capability, and prompt surgical or endovascular intervention, as well as effective teamwork in the emergency department, are critical to avoid the devastating consequences of a ruptured visceral artery aneurysm.
Patients with a Blom® tracheostomy tube (containing a cuff) can vocalize while on mechanical ventilation, which can significantly improve the patient's quality of life. This is brought by the purpose-built structure of the tracheostomy tube that allows the expiration to be expelled through the glottis. However, this characteristic may complicate the measurement of the patient's tidal volume, as most of the expiration does not return to the ventilator. Owing to the necessity of insertion of the speech cannula, which acts as an inner cannula, to enable patient vocalization, the air passage likely becomes constricted, thus increasing airway resistance. Difficulty in applying appropriate positive end-expiratory pressure (PEEP) and ventilator auto-triggering may also be problematic. Therefore, alveolar ventilation is predicted to decrease without adjusting the ventilation settings. Our experience using the Blom® tracheostomy tube revealed some problems, and we provide suggestions for patient management. We herein report on the experience of a patient having inserted the Blom® tracheostomy tube receiving mechanical positive pressure ventilation during vocal training.
