Preoperative elevated E/e' (≥ 15) with preserved ejection fraction is associated with the development of postoperative heart failure in intermediate-risk non-cardiac surgical patients.

PURPOSE: Left ventricular diastolic dysfunction is an independent risk factor for adverse cardiovascular morbidities and mortalities in cardiovascular and high-risk surgical patients. However, there were only a few investigations among intermediate-risk surgical patients. This study aimed to investigate postoperative heart failure (HF) in intermediate-risk surgical patients who had preoperative diastolic dysfunction with preserved ejection fraction (EF). METHODS: Consecutive patients underwent intermediate-risk surgery between January 2016 and December 2018 were retrospectively evaluated. Patients with preserved EF were divided into three groups using one of the parameters of diastolic function: the ratio of early diastolic filling velocity to the peak diastolic velocity of mitral medial annulus (E/e') ≥ 15, E/e' between 8 and 15, and E/e' < 8. Postoperative HF was defined as clinical symptoms and radiological evidence and low SpO2 less than 93%. The primary outcome was the incidence of postoperative HF and its relation to preoperative E/e'. Chi-squared test, unpaired t test with Welch's correction, and multivariate logistic regression were used for analysis. RESULTS: In total, 965 patients were included in the final analysis. Postoperative HF developed in 36/965 (3.7%) patients with preserved EF. The incidence of postoperative HF was stratified according to the E/e', and the rates of HF occurrence in patients with E/e' < 8, 8-15, and ≥ 15 were 1.8%, 2.7%, and 15%, respectively (P < 0.01). CONCLUSION: Preoperative elevated E/e' (≥ 15) was associated with the development of postoperative HF in intermediate-risk surgical patients with preserved EF.

Drug-induced Interstitial Lung Disease Has the Same Degree of Risk for Mortality as Old Age in Patients With Lung Cancer.

BACKGROUND/AIM: The aim of this study was to investigate the impact of drug-induced interstitial lung disease (DILD) on the mortality of patients with lung cancer. PATIENTS AND METHODS: Japanese patients with lung cancer who had received chemotherapy in Fujita Health University Hospital from January 2017 to December 2018 were enrolled in this study. The primary outcome was to identify independent factors associated with patient mortality. The secondary outcome was to identify the risk factor of DILD. RESULTS: Four hundred and fifty-seven patients were assigned to the current study. The multivariable analysis revealed that being aged 75 years or older, small cell lung carcinoma, cancer stage IV, and DILD event were risk factors of mortality. Male sex was identified as a risk factor of DILD. CONCLUSION: DILD event has the same degree of risk for mortality as age 75 years or older in lung cancer patients.

Prognosis of Patients With Interstitial Lung Disease Induced by Different Pharmacological Types of Anticancer Drugs.

BACKGROUND/AIM: The aim of this study was to evaluate the effect of drug-induced interstitial lung disease (DILD) on treatment outcomes by comparing the mortality of patients with DILD induced by different pharmacological types of anticancer drugs. PATIENTS AND METHODS: Japanese patients with lung cancer who had received chemotherapy at Fujita Health University Hospital were enrolled. The primary outcome was the short-term mortality rate from the administration of chemotherapy that might have caused DILD. RESULTS: Eleven, 16, and 20 patients with DILD were assigned to the kinase inhibitor (KI), immune-checkpoint inhibitor (ICI), and cytotoxic anticancer drug groups, respectively. The 90-day mortality rate after the DILD event in the group treated with cytotoxic anticancer drugs was significantly higher than in the KI and ICI groups. CONCLUSION: Patients with DILD induced by cytotoxic anticancer drugs have poorer prognoses than those with DILD induced by KIs or ICIs.

Anesthetic management of multiple acyl-coenzyme A dehydrogenase deficiency in a series of surgeries under general anesthesia: a case report.

BACKGROUND: Glutaric acidemia is a type of multiple acyl-coenzyme A dehydrogenase deficiency, an inborn error in fatty acid metabolism. In patients with glutaric acidemia, during the perioperative period, prolonged fasting, stress, and pain have been identified as risk factors for the induction of metabolic derangement. This report describes the surgical and anesthetic management of a patient with glutaric acidemia. CASE PRESENTATION: A 56-year-old male patient with glutaric acidemia type 2 underwent a series of surgeries. During the initial off-pump coronary artery bypass surgery, the patient developed renal failure due to rhabdomyolysis upon receiving glucose at 2 mg/kg/min. However, in the second laparoscopic cholecystectomy, rhabdomyolysis was avoided by administering glucose at 4 mg/kg/min. CONCLUSIONS: To avoid catabolism in patients with glutaric acidemia, appropriate glucose administration is important, depending on the surgical risk.

[Complications of internal jugular vein cannulation under ultrasound guidance: report of three].

Internal jugular cannulation with ultrasound guidance has been advocated to decrease its complications. However, there can be serious complications by in-experienced physicians in even ultrasound-guided internal jugular vein cannulation. We report three cases of complications associated with ultrasound-guided internal jugular vein cannulation: puncture of the common carotid artery in two patients and pneumothorax in one.
