Haemorrhage occurring 2-3 hours after extraction is known as?

The correct answer is reactionary haemorrhage, which refers to bleeding that occurs after the initial clot formation, typically 2-3 hours post-extraction. This type of haemorrhage can happen due to various factors, such as physical activity, changes in blood pressure, or the disruption of the clot forming site.

In the context of dental procedures, reactionary haemorrhage is significant because it indicates that the blood vessels around the extraction site may not have completely stabilized, leading to the potential for rebleeding. Understanding this aspect is crucial for dental nurses and practitioners, as it informs post-operative care and patient instructions.

Primary haemorrhage generally occurs immediately or very soon after the procedure, which refers to the bleeding that happens during the extraction itself or right afterward. Delayed haemorrhage occurs later, typically more than 24 hours later. Capillary haemorrhage describes a specific type of bleeding from small blood vessels and does not categorize the timing relative to the procedure. Knowing these distinctions helps dental nurses provide better monitoring and advice to patients post-extraction.
