[Autoptical display of the nasopharyngeal space in cases of suspected SARS-Co2 infection]

This paper deals with a dissection technique in order to display the nasopharyngeal space. It consists of a parafrontal saw cut through the base of the skull at the level of the sella turcica. In this way the ventral part of the nasopharyngeal space can be separated from the cervical spine and the posterior base of the skull within an anatomically preformed border region. Apart from a comprehensive overview of the nasopharyngeal space, this technique also enables samples to be correctly taken. The time required takes approximately 2-3 min, the external appearance of the deceased is not affected and the preparation of the body is not complicated.

[COVID-19-associated deaths]

INTRODUCTION

In December 2019, the new infectious coronavirus disease 2019 (COVID-19) first appeared in China. So far, no systematic evaluation of death certificates of COVID-19-associated deaths has been presented.

METHODS

The death certificates of all deaths in Munich during the period from 1 March to 31 July 2020 were analyzed. The previously defined inclusion criteria were the indication of corona, COVID-19 and SARS-CoV‑2 in the death certificates. The variables were entered anonymously according to a developed key. The collected data were evaluated descriptively.

RESULTS

In the period under investigation, a total of 5840 people died in the Munich City area. Of these deaths 332 (5.7%) were COVID-19-associated. In 281 deaths (84.6%) there was a definite COVID-19 and in 51 deaths (15.4%) the suspicion of this disease. The most frequent causes of death were acute respiratory distress syndrome or respiratory insufficiency (59.1%), multiple organ failure (21.4%) and sepsis (10%). An average of 1.8 pre-existing illnesses were reported in the death certificates. Most frequently mentioned were diseases of the circulatory system (54.8%), the nervous system (22.8%) and metabolic diseases (18.9%). The average age at death was 79 years and the most frequent place of death was a hospital (85%). An autopsy was attempted by the doctors who issued the death certificates for 18.1% of the collective, most frequently in the case of unexplained or unnatural causes of death and young age of the deceased. Clinical pathological autopsies were performed on 11% of the collective and judicial autopsies on 1%.

DISCUSSION

This study is the first evaluation of death certificates with respect to the novel infectious COVID-19. Number and essential characteristics of COVID-19-associated deaths in Munich during the so-called first wave could be mapped. The interest of physicians in autopsies was rather low despite the appearance of a new infectious disease.
