Penatalaksanaan sakit kritis pada wanita hamil memiliki karakteristik yang unik karena  perubahan fisiologi selama kehamilan dan janin yang berkembang dalam uterus yang mendapat implikasi yang signifikan. Pada kasus ini, seorang perempuan 27 tahun yang sedang hamil gemeli usia kehamilan 29–30 minggu datang ke Instalasi Gawat Darurat (IGD) Rumah Sakit Dr. Hasan Sadikin Bandung dengan keluhan utama kelemahan keempat anggota gerak. Hasil pemeriksaan laboratorium didapatkan kadar kalium sangat rendah dan didiagnosis dengan hypokalemic periodic paralysis. Pasien mengalami gagal napas  sehingga dilakukan intubasi dan diberikan bantuan ventilasi mekanik, kemudian dirawat di Intensive Care Unit (ICU). Gagal napas disertai penyulit community acquired pneumonia. Tata laksana ventilasi mekanik pada wanita hamil di ICU bersifat suportif dengan teknik sama seperti pada pasien tidak hamil, namun memiliki target khusus yang berbeda. Monitoring fetal heart rate (FHR) dapat mencerminkan kesejahteraan janin dan kondisi ibu. Tujuan penulisan laporan kasus ini adalah mengetahui pentingnya target pemberian ventilasi mekanik dan melakukan monitoring FHR pada pasien hamil di ICU. Management of Respiratory Failure Due to Hypokalemic Periodic Paralysis Complicated with Community Acquired Pneumonia in 29–30 Weeks of GestationManagement of critically ill pregnant women in Intensive Care Unit (ICU) has unique characteristics due to the physiological changes during pregnancy and the presence of growing fetus in the uterine which may present significant implications. This study presented a case of a 27 years old woman with 29–30 weeks of gestation of twin pregnancy who came to Emergency Room (ER) with the chief complaint of weakness in both lower and upper extremities. Laboratory investigations showed a very low potassium level and the patient was diagnosed with hypokalemic periodic paralysis. Patient then experienced respiratory failure at the ER, intubated, and mechanically ventilated and was sent to the ICU. Community-acquired pneumonia was complicating the respiratory failure. Basically, mechanical ventilation management for pregnant patient in ICU is supportive in nature and uses the same techniques employed for the non-pregnant patient. However, the goals are different as it is important to monitor fetal heart rate (FHR) in pregnant woman as this does not only reflect the fetal well-being but also the maternal condition. This case report is intended to show the importance of mechanical ventilation goal and FHR monitoring in pregnant patients in ICU.

Abstract Background The COVID-19 pandemic reached Europe in early 2020. Convalescent plasma is used without a consistent evidence of efficacy. Our hypothesis is that passive immunization with plasma collected from patients having contracted COVID-19 and developed specific neutralizing antibodies may alleviate symptoms and reduce mortality in patients treated with mechanical ventilation for severe respiratory failure during the evolution of SARS-CoV-2 pneumonia. Methods We plan to include 500 adult patients, hospitalized in 16 Belgian intensive care units between September 2020 and 2022, diagnosed with SARS-CoV-2 pneumonia, under mechanical ventilation for less than 5 days and a clinical frailty scale less than 6. The study treatment will be compared to standard of care and allocated by randomization in a 1 to 1 ratio without blinding. The main endpoint will be mortality at day 28. We will perform an intention to treat analysis. The number of patients to include is based on an expected mortality rate at day 28 of 40 percent and an expected relative reduction with study intervention of 30 percent with α risk of 5 percent and β risk of 20 percent. Discussion This study will assess the efficacy of plasma in the population of mechanically ventilated patients. A stratification on the delay from mechanical ventilation and inclusion will allow to approach the optimal time use. Selecting convalescent plasmas with a high titer of neutralizing antibodies against SARS-CoV-2 will allow a homogeneous study treatment. The inclusion in the study is based on the consent of the patient or his/her legal representative, and the approval of the Investigational Review Board of the University hospital of Liège, Belgium. A data safety monitoring board (DSMB) has been implemented. Interim analyses have been planned at 100, 2002, 300 and 400 inclusions in order to decide whether the trail should be discontinued prematurely for ethical issues. We plan to publish our results in a peer-reviewed journal and to present them at national and international conferences. Funding and registration The trial is funded by the Belgian Health Care Knowledge Center KCE # COV201004 Trial registration Clinicaltrials.gov registration number NCT04558476.

Abstract Background One of the main symptoms of severe infection with the new coronavirus‑2 (SARS-CoV-2) is hypoxemic respiratory failure because of viral pneumonia with the need for mechanical ventilation. Prolonged mechanical ventilation may require a tracheostomy, but the increased risk for contamination is a matter of considerable debate. Objective Evaluation of safety and effects of surgical tracheostomy on ventilation parameters and outcome in patients with COVID-19. Study design Retrospective observational study between March 27 and May 18, 2020, in a single-center coronavirus disease-designated ICU at a tertiary care German hospital. Patients Patients with COVID-19 were treated with open surgical tracheostomy due to severe hypoxemic respiratory failure requiring mechanical ventilation. Measurements Clinical and ventilation data were obtained from medical records in a retrospective manner. Results A total of 18 patients with confirmed SARS-CoV‑2 infection and surgical tracheostomy were analyzed. The age range was 42–87 years. All patients received open tracheostomy between 2–16 days after admission. Ventilation after tracheostomy was less invasive (reduction in PEAK and positive end-expiratory pressure [PEEP]) and lung compliance increased over time after tracheostomy. Also, sedative drugs could be reduced, and patients had a reduced need of norepinephrine to maintain hemodynamic stability. Six of 18 patients died. All surgical staff were equipped with N99-masks and facial shields or with powered air-purifying respirators (PAPR). Conclusion Our data suggest that open surgical tracheostomy can be performed without severe complications in patients with COVID-19. Tracheostomy may reduce invasiveness of mechanical ventilation and the need for sedative drugs and norepinehprine. Recommendations for personal protective equipment (PPE) for surgical staff should be followed when PPE is available to avoid contamination of the personnel.

Abstract Background The severity of coronavirus disease 2019 (COVID-19) is highly variable between individuals, ranging from asymptomatic infection to critical disease with acute respiratory distress syndrome requiring mechanical ventilation. Such variability stresses the need for novel biomarkers associated with disease outcome. As SARS-CoV-2 infection causes a kidney proximal tubule dysfunction with urinary loss of uric acid, we hypothesized that low serum levels of uric acid (hypouricemia) may be associated with severity and outcome of COVID-19. Methods In a retrospective study using two independent cohorts, we investigated and validated the prevalence, kinetics and clinical correlates of hypouricemia among patients hospitalized with COVID-19 to a large academic hospital in Brussels, Belgium. Survival analyses using Cox regression and a competing risk approach assessed the time to mechanical ventilation and/or death. Confocal microscopy assessed the expression of urate transporter URAT1 in kidney proximal tubule cells from patients who died from COVID-19. Results The discovery and validation cohorts included 192 and 325 patients hospitalized with COVID-19, respectively. Out of the 517 patients, 274 (53%) had severe and 92 (18%) critical COVID-19. In both cohorts, the prevalence of hypouricemia increased from 6% upon admission to 20% within the first days of hospitalization for COVID-19, contrasting with a very rare occurrence (< 1%) before hospitalization for COVID-19. During a median (interquartile range) follow-up of 148 days (50–168), 61 (12%) patients required mechanical ventilation and 93 (18%) died. In both cohorts considered separately and in pooled analyses, low serum levels of uric acid were strongly associated with disease severity (linear trend, P < 0.001) and with progression to death and respiratory failure requiring mechanical ventilation in Cox (adjusted hazard ratio 5.3, 95% confidence interval 3.6–7.8, P < 0.001) or competing risks (adjusted hazard ratio 20.8, 95% confidence interval 10.4–41.4, P < 0.001) models. At the structural level, kidneys from patients with COVID-19 showed a major reduction in urate transporter URAT1 expression in the brush border of proximal tubules. Conclusions Among patients with COVID-19 requiring hospitalization, low serum levels of uric acid are common and associate with disease severity and with progression to respiratory failure requiring invasive mechanical ventilation.
