Summary
Advanced maternal age, severe anemia, prior post-partum hemorrhage, and home delivery are key risk factors for post-partum hemorrhage (PPH). Identifying these risks aids in preventing this critical obstetric complication.
Area of Science:
- Obstetrics and Gynecology
- Reproductive Health
- Maternal Medicine
Background:
- Post-partum haemorrhage (PPH) is a significant cause of maternal morbidity and mortality worldwide.
- Identifying risk factors is crucial for effective prevention and management strategies.
- Previous studies have explored various risk factors, but a comprehensive model is needed.
Purpose of the Study:
- To analyze the significance of various demographic and obstetric risk factors associated with post-partum haemorrhage (PPH).
- To construct a final risk assessment model for PPH using logistic regression.
Main Methods:
- A case-control study was conducted involving 62 patients with PPH (cases) and randomly selected controls.
- Data on demographic factors (age, parity) and obstetric factors were collected.
- Spearman test and logistic regression were used for statistical analysis.
Main Results:
- Significant risk factors identified through bivariate analysis included advanced age (>35 years), high parity, moderate to severe anemia, previous PPH, polyhydramnios, placenta praevia, morbidly adherent placenta, and home birth.
- The final logistic regression model identified advanced age (>35 years), anemia, previous history of PPH, and home delivery as independent risk factors for PPH.
- Uterine atony was the most frequent cause of PPH (58.1%).
Conclusions:
- Advanced maternal age, moderate to severe anemia, a history of PPH, and home delivery are independently associated with an increased risk of PPH.
- These identified factors can guide clinical practice and public health interventions to reduce PPH incidence.

01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:12Relative Risk
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

01:23Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...
