Delivery by extension. The back of the neck presses against the pubic bone and its chin leaves its chest, extending the neck – as if to look up, and the rest of its head passes out of the birth canal. Restitution. The fetal head turns through 45 degrees to restore its normal relationship with the shoulders, which are still at an angle. External rotation. The shoulders repeat the corkscrew movements of the head, which can be seen in the final movements of the fetal head.Failure to complete the cardinal movements of birth in the correct order may result in complications of labour and birth injuries. Early skin-to-skin contact
Skin-to-skin contact (SSC), sometimes also called kangaroo care, is a technique of newborn care where babies are kept chest-to-chest and skin-to-skin with a parent, typically their mother, though more recently (2022) their father as well. This means without the shirt or undergarments on the chest of both the baby and parent. A 2011 medical review found that early skin-to-skin contact resulted in a decrease in infant crying, improved cardio-respiratory stability and blood glucose levels, and improved breastfeeding duration. A 2016 Cochrane review also found that SSC at birth promotes the likelihood and effectiveness of breastfeeding.As of 2014, early postpartum SSC is endorsed by all major organizations that are responsible for the well-being of infants, including the American Academy of Pediatrics. The World Health Organization (WHO) states that "the process of
childbirth is not finished until the baby has safely transferred from placental to mammary nutrition."
Gas gangrene (also known as clostridial myonecrosis and myonecrosis) is a bacterial infection that produces tissue gas in gangrene. This deadly form of gangrene usually is caused by Clostridium perfringens bacteria. About 1,000 cases of gas gangrene are reported yearly in the United States.Myonecrosis is a condition of necrotic damage, specific to muscle tissue. It is often seen in infections with C. perfringens or any of myriad soil-borne anaerobic bacteria. Bacteria cause myonecrosis by specific exotoxins. These microorganisms are opportunistic and, in general, enter the body through significant skin breakage. Gangrenous infection by soil-borne bacteria was common in the combat injuries of soldiers well into the 20th century, because of non-sterile field surgery and the basic nature of care for severe projectile wounds.Other causes of myonecrosis include envenomation by snakes of the genus Bothrops (family Viperidae), ischemic necrosis, caused by vascular blockage (e.g., diabetes type II), tumours that block or hoard blood supply, and disseminated intravascular coagulation or other thromboses. Presentation
Gas gangrene can cause myonecrosis (muscle tissue death), gas production, and sepsis. Progression to toxemia and shock is often very rapid. It can easily be noticed by the large, blackened sores that form, as well as a degree of loud and distinctive crepitus caused by gas escaping the necrotic tissue. Symptoms
A multitude of symptoms is associated with Gas gangrene. Distinctively, black lesions on the skin appear in a bubble form which allows visualization of gas-producing bacteria.
