Blood pressure measurement in very obese patients: a challenging problem

Preventing hypotension-induced nausea and vomiting during spinal anesthesia for Cesarean delivery in obese parturients: a small solution for a big problem?

“…2 Bien que cela puisse être lié à des différences dans les taux de perfusion, il est intéressant d'examiner si l'obésité a eu un effet sur le délai d'action ou l'étendue du bloc (bien que cela soit discutable, comme le soulignent les auteurs), sur la compression aorto-cave 6 et aussi sur les artéfacts de mesure. 7 Malgré l'incertitude quant à ses causes, une forte prédilection à l'hypotension soulignerait que les parturientes obèses constituent une population à risque.…”

“…2 Although this may relate to differences in infusion regimens, it is interesting to consider whether obesity might predispose to increased hypotension via an effect on the onset speed or extent of the block (although contentious, as highlighted by the authors), aortocaval compression, 6 or measurement artifacts. 7 Despite the uncertainty of the explanation, a high predilection to hypotension would put emphasis on recognizing obese parturients as an at-risk population.…”

The Concerns of Blood Pressure Monitoring in Arterial Hypertension Outpatients

“…Исходя из этого, клиническая актуальность проблемы точного измерения и правильной фикса-ции значений АД не подлежит сомнению [6][7][8].…”

Arm Circumference, Shape, and Length: How Interplaying Variables Affect Blood Pressure Measurement in Obese Persons

“…7 In conclusion, consistent use of methods for measuring blood pressure is imperative for accurate yields a false underestimate of blood pressure (range of error, 10-30 mm Hg). 9,10 These anatomic challenges and the many cuff choices are compounded by the potential lack of consistent use of a particular cuff size between clinicians, further reducing the reliability of blood pressure values that guide critical treatment decisions. As a result, the following PICO (population, intervention, control, and outcomes) question was chosen for this clinical review: What is the most accurate method of assessing blood pressure in obese persons?…”

“…9 Such "undercuffing" leads to overestimates of systolic blood pressure (SBP) and diastolic blood pressure (DBP; range of error, 2.4-30 mm Hg), resulting in erroneous classification of patients as hypertensive, leading to unnecessary therapy. [8][9][10] A regular feature of the American Journal of Critical Care, Clinical Evidence Review unveils available scientific evidence to answer questions faced in contemporary clinical practice. It is intended to support, refute, or shed light on health care practices where little evidence exists.…”
