The strongest argument against caesarean delivery relates to maternal complications. Evidence supporting this for elective operations is controversial. The perinatal database 1998-2001 of the German state of Baden-Württemberg was studied to assess the maternal obstetrical risk associated with caesarean delivery with regard to puerperal infectious complications. For statistical analysis the chi2 test, Fisher's exact test, Mantel-Haenszel statistics and relative risks were used to describe the risk of exposure. Surgical delivery was associated with a significantly higher risk of infectious disorders (p < 0.0001). There was a significantly higher risk of septicaemia in the group undergoing caesarean compared to vaginal delivery (p < 0.0001), for pregnancies with and without risk factors of infection, and also for caesarean delivery prior to labour and rupture of membranes (ROM) and singleton gestations (RR 8.56; 95% CI 4.4-16.65, stratum without risks). The rate of wound disorders was found to be significantly increased in the case of surgical delivery (p < 0.0001). After exclusion of pregnancies with risk factors for infectious complications and multi-fetal gestation, a significantly higher risk was also found for caesarean delivery prior to labour and ROM versus vaginal delivery (RR 16.97; 95% CI 14.16-20.34). Caesarean delivery significantly increased the likelihood that a woman would experience fever in puerperium (p < 0.0001), for pregnancies with and without ante- or perinatal risk factors for infectious complications, and also when caesarean delivery prior to labour and ROM and singletons in the cephalic presentation were considered separately (RR 11.03; 95% CI 9.39-12.96; stratum without risks). Considering the obstetrical challenge of how more women can deliver with fewer complications, reducing unnecessary caesarean delivery still seems to be an appropriate approach.

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
Standard Precaution01:26

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...
