Incidence of perioperative complications in COVID-19 survivors: Prospective observational clinical trial.

BACKGROUND: As long as the COVID-19 pandemic continued, the continuation of elective surgery had been unavoidable. There is still no consensus on the timing of elective surgery in patients who have recovered from COVID-19. The primary aim of this study was to determine the effect of time after COVID-19 infection on perioperative complications. METHODS: This prospective observational single center included adult patients who had recovered from COVID-19 and underwent surgery between February and July 2021. Data were prospectively collected from the patient and hospital database, the preoperative evaluation form and the perioperative anesthesia forms. RESULTS: A total of 167 patients were included in our study. Preoperative COVID-19 RT-PCR test results were negative in all patients. The mean time of positive COVID-19 diagnosis was 151.0 ± 74.0 days before the day of surgery. Intraoperative general and airway complications occurred in 33 (19.8%) and 17 (10.2%) patients, respectively. Although the time from COVID-19 positivity to surgery was shorter in patients with intraoperative general and airway complications, the difference between the groups did not reach statistical significance (P = .241 and P = .133, respectively). The median time from COVID-19 positivity to surgery in patients with and without postoperative complications was 156.0 (min: 27.0-max: 305.0) and 148.5 (min: 14.0-max: 164.0) days, respectively (P = .757). In patients with and without oxygen support in the postoperative period, the median time from COVID-19 positivity to surgery was 98.0 (min: 27.0-max: 305.0) and 154.0 (min: 14.0-max: 364.0) days, respectively. In patients who received oxygen support in the postoperative period, the time from COVID-19 positivity to surgery was shorter and the difference between the groups was statistically significant (P = .014). CONCLUSIONS: The incidence of perioperative complications decreased with increasing time after a positive SARS-CoV-2 infection, but there was no difference in perioperative complications between the groups. As the time between COVID-19 positivity and surgery increased, the need for oxygen support in the postoperative period decreased. It is not possible to share clear data on the timing of operation after SARS-CoV-2 infection.

Fetal cardiac interventions: First-year experience of a tertiary referral center in Turkey.

AIM: To present the first-year experience of fetal cardiac interventions (FCIs) in a tertiary referral hospital and to evaluate the outcomes. METHODS: This retrospective study consisted of four pregnant women who underwent fetal pulmonary or aortic balloon valvuloplasty between November 2020 and June 2021. The procedures were performed with a percutaneous cardiac puncture under the ultrasonography guidance. Gestational age at intervention, procedural success, complications, and perinatal outcomes were evaluated. Procedural complications defined as fetal bradyarrhythmia requiring treatment, pericardial effusion requiring drainage, balloon rupture, and fetal death. The procedure was considered technically successful if the valve was dilated with a balloon catheter. Ultimately successful procedure was defined as the discharge of infants alive with biventricular circulation. RESULTS: A total of 5 FCIs attempted between 26 + 3 and 28 + 2 gestational weeks. While the procedure was technically successful in 2 cases with pulmonary stenosis, both attempts were unsuccessful in the fetus with pulmonary atresia. Although the procedure was technically successful in the patient with critical aortic stenosis, it ultimately failed. No fetal death occurred in our series and there were no procedure-related significant maternal complications. However, three interventions were complicated by fetal bradycardia and pericardial effusion necessitating treatment, and balloon rupture cropped up in one case. CONCLUSION: FCIs may lead to improving the likelihood of a biventricular outcome for selected fetuses. Careful selection of patients and centralization of experience are essential for obtaining favorable outcomes. Operators should be aware of procedural complications. Improved procedural techniques with a lower complication rate will be achieved through advanced medical technology and special balloon catheters.
