Comentarios al artículo «Tratamiento anestesiológico de la fractura de pelvis “en libro abierto” secundaria a explosión». BMC Cardiovasc Disord. Patients undergoing emergency laparot-omy and thoracotomy for blunt and penetrating trauma, who had had at least one in-hospital documented SBP ≤90 mmHg, were included in the study. Chestnut et al. There is a brief outline of the equipment used for manually measuring blood pressure, followed by some factors that may affect the accuracy of the final reading. A target ‘normal’ SBP of > 100 mmHg was compared with a hypotensive target of 70 mmHg in 110 patients, of whom around 50% had suffered blunt traumatic injuries. Modern trauma management focuses upon the principles of haemostatic resuscitation by the early replacement of coagulation factors and platelets in conjunction with antifibrinolyic therapy. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. One area of focus is the concept of permissive hypotension as part of a damage control resuscitation (DCR) strategy in the management of the bleeding trauma patient. These guidelines have faced increasing criticism over the past decade, especially regarding their insensitivity to change (with updates typically occurring on a 3–4 year cycle) and applicability to UK practice 5, 6.

A UK trial 27 looked at the pre‐hospital administration of intravenous fluids by paramedics to adult trauma patients. Similar results were seen in patients with penetrating trauma, with mortality doubling with SBP < 110 mmHg and becoming four‐ to ten‐fold higher at < 90 mmHg 41. Typical systolic blood pressure (SBP) targets in permissive hypotension are 70–90 mmHg although a recent article 12 has suggested that DCR targets should be a SBP and mean arterial pressure (MAP) of 80 and 50 mmHg, respectively. Accurately measuring blood pressure: factors that contribute to false measurements. 17, a group of Captains in the Army Medical Corps, from their experience in the management of injuries received during the First World War.

The direct translation of research done in animal models to clinical practice in humans should be undertaken with caution. Trauma patients are a complex population, with each individual requiring a unique management strategy tailored to his/her needs – the acceptance of a single global blood pressure target would appear to be the antithesis of this principle. As a result, European guidelines for the management of traumatic brain injury recommend the early maintenance of a MAP > 80 mmHg or SBP > 120 mmHg 32, 33. The cause of death of these patients is not discussed in the paper, and so it is not clear whether they represent the most haemodynamically unstable subjects. Citation: Jevon P (2020) Blood pressure 1: key principles and types of … In pregnant trauma patients, initial priority is stabilization of the woman, which is the best way to ensure fetal stability. Background: The manual recording of blood pressure is widely accepted to be more accurate than the recording of blood pressure using an automated device. Midwifery basics. 's animal models of controlled haemorrhage throughout the 1940s 19 led to the recognition of the reversible nature of shock with volume replenishment. Permissive hypotension (or hypotensive resuscitation) was conceived because of the theoretical risk of excess fluid administration's interfering with the endogenous coagulation process, by inducing a dilutional coagulopathy, by clot disruption from an increase in arterial pressure, or through the abolition of reflex physiological vasoconstriction. This led to the recommendation that fluid administration should be delayed until haemorrhage has been controlled, even though this often would result in a period of suboptimal end‐organ perfusion. The author defines blood pressure and the terms systolic and diastolic and explores the purpose of manual measurement. It is of note that over 20% of the study participants had suffered a head injury. In‐hospital survival in the group who only received intravenous crystalloid once they reached the operating theatre was significantly higher than those who received fluid in the pre‐hospital environment and emergency department (70% vs 62%, respectively, p = 0.04). This led to a review of major trauma care within England by the National Audit Office 2, which subsequently led to the creation of major trauma centres (MTCs). 2010 Mar-Apr;19(2):90-4; quiz 95. The concept of permissive hypotension was first described by Cannon et al. showed in a retrospective analysis of severely brain‐injured patients that a single episode of hypotension (SBP < 90 mmHg) was associated with a doubling of mortality and a parallel increase in morbidity rates amongst survivors 31.
