Methods: This observational study included 94 patients aged &gt;65 years with hip fracture. Demographic data, pre-operative heart rate, non-in-vasive arterial pressures, PVI values, and haemogram values were continuously measured following spinal anaesthesia. The measurements with and without hypotension were distinguished and their data were compared. Results: The mean age of the patients was 77.4±8.2 years. In total, 56.4% of the patients developed hypotension after spinal anaesthesia, and hypotension was higher in women (p=0.037). Low pre-operative diastolic arterial pressures values were associated with the development of hy-potension (p=0.037). The relationship between PVI and post-spinal hypotension was negative but significant (r=−0.239; p&lt;0.05). Depending on the volume loss, an increase in the PVI (p&lt;0.001) and its subsequent significant decrease after treatment in patients with hypotension (p&lt;0.001) was observed. The correlation between noninvasively measured haemoglobin values and the values obtained from arterial blood gas samples was significant (p&lt;0.001). Conclusion: This study showed that post-spinal hypotension may be associated with increased as well as decreased PVI values. However, these values cannot be clinically used for predicting pre-operative hypotension in hypovolemic patients. © 2020 by Turkish Society of Anaesthesiology and Reanimation-Available online at www.jtaics.org.</dc:description><dc:publisher>AVES</dc:publisher><dc:date>2020</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/13694</dc:identifier><dc:identifier>https://doi.org/10.5152/tjar.2019.59251</dc:identifier><dc:identifier>2667-677X</dc:identifier><dc:language>en</dc:language><dc:relation>Turkish Journal of Anaesthesiology and Reanimation</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/13694</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
