Summary

Intra-operative hypotension is linked to increased postoperative morbidity and mortality. Intra-operative MAP below 60-70 mmHg or SBP below 100 mmHg increase the risk of post operative myocardial injury, acute kidney injury and death. accurate measurement of blood pressure is fundamental in proper mangement of intraperative hypotension.

Measurement of arterial blood pressure through an arterial catheter is restricted to patients with major, rapid changes in blood pressure in the operating room as well as the intensive care units. Among non-invasive blood pressure (NIBP) monitors, oscillometric blood pressure measuring technology is considered the standard and the most widely used method in medical practice. In oscillometric blood pressure monitor, a pressure transducer located in the cuff senses the maximal arterial oscillation, which represents the mean arterial pressure, and according to the device's algorithm the systolic and diastolic blood pressure (SBP and DBP) will be calculated.

The upper arm is the standard location of application of the blood pressure cuff as it is aligned with the heart level regardless the patient position. Many surgical procedures, sometimes major, are conducted in the lateral position; during these operations, the choice of the side for application of the NIBP cuff is a challenging decision with no clear recommendations. The non-dependent upper limb is claimed to be inaccurate measurement site because the cuff position is above the level of the heart. While, the dependent upper limb might be affected by compression of the axilla and the upper arm. No data, to the best of our knowledge are available for the accuracy of NIBP in both upper limbs in the lateral position using the invasive arterial blood pressure (IBP) as a reference for detecting intraoperative hypotension.
