China Medical University Forensic Medicine Asphyxia

Abstract

Although China has advanced as a leading economic world power since World War II, its perinatal health outcomes, including neonatal mortality, have lagged behind those of other rapidly developing countries. Some factors behind the relatively high neonatal mortality rate include geographic challenges to providing health care in rural regions and disparities in care across different levels of hospitals. To tackle the problem of neonatal mortality, specifically to reduce birth asphyxia, key stakeholders have worked to implement the Neonatal Resuscitation Program and Helping Babies Breathe initiatives across China in the past decade. These efforts have already borne fruit in improving clinical care and are likely to provide further benefit in improving long-term outcomes.

Asphyxial Deaths and Petechiae: A Review

ABSTRACT:

Conjunctival and facial petechiae, although nonspecific findings, are considered hallmarks of asphyxial deaths. Consensus in the literature suggests that their pathogenesis is related to the combined effects of increased cephalic venous pressure and hypoxic damage to endothelial cells. Despite the common knowledge that they are neither predictable findings in all asphyxial deaths nor rare in natural, nonaphyxial deaths, the belief persists that petechiae are corroborative evidence of asphyxia. We suggest that a clear, physiologically based understanding of the pathogenesis of petechiae of the head is critical for their appropriate interpretation. We present a review of the literature and the basis of our conclusion that conjunctival and facial petechiae are the product of purely mechanical vascular phenomena, unrelated to asphyxia or hypoxia.

Conjunctival and facial petechiae have been regarded as classic signs of asphyxial deaths (1–11). First described by Tardieu in the nineteenth century, external and visceral petechiae have since been interpreted as hypoxia-related sequelae of asphyxia, sometimes being attributed in part to......

SUFFOCATION

SMOTHERING
Smothering and suffocation are often used interchangeably, but the term “smothering” is best used for that form of asphyxia in which the nose and mouth are obstructed e.g. by a hand, paper, clothes, pillow, plastic bag etc. Gagging people to keep them quiet may lead to smothering. Signs of asphyxia are commonly absent or are only slight, and because marks of injury may be few if any at all homicidal smothering may be difficult to diagnose. Overlaying is the accidental death by smothering of young children by adults sleeping with them. In the U.K. it is a criminal offence...

The Relationship Between Serial Sexual Murder And Autoerotic Asphyxiation

Abstract

This case series documents and examines the association between autoerotic asphyxiation, sadomasochism, and serial sexual murderers. Autoerotic asphyxiation, along with other paraphilias found in this population, is reviewed. Five cases of serial sexual killers who engaged in autoerotic asphyxiation were identified worldwide: four from the United States and one from Russia. Case reports for each are provided. All (100%) were found to have sexual sadism in addition to autoerotic asphyxiation. Furthermore, two (40%) had bondage fetishism, and two (40%) had transvestic fetishism, consistent with these paraphilias co-occurring in those with autoerotic asphyxiation. Overall the group averaged 4.0 lifetime paraphilias. Some possible relationships were observed between the offenders’ paraphilic orientation and their modus operandi, e.g., all of these serial killers strangled victims suggesting an association between their sadistic and asphyxiative paraphilic interests. The overlap of seemingly polar opposite paraphilias in this sample sexual sadism and autoerotic asphyxiation is explored from a historical and clinical perspective.
