Painful unanesthetized arterial puncture may produce transient hyperventilation, and this hyperventilation might alter resting values of arterial pH and PCO2. We investigated this possibility by comparing pH and PCO2 values of blood samples obtained by arterial puncture with values of arterialized venous blood obtained by a painless method. In 19 consecutive subjects, virtually no difference in pH or PCO2 resulted from an arterial puncture that could not be attributed to the inherent precision of the measuring instrument. Mean +/- SEM pH was identical (7.45 +/- 0.05) both before and during an arterial puncture, as was PCO2 (34.4 +/- 1.2 mm Hg). The variation (SD) in PCO2 within an individual subject was +/- 1.7 mm Hg, which was almost identical to the inherent precision of the Radiometer ABL-2 acid base laboratory (SD, +/- 1.32). We conclude that an unanesthetized arterial puncture provides an accurate measurement of resting pH and PCO2.

Background: This study evaluates the safety and effectiveness of coil embolization of the superior rectal artery for both emergency and elective treatment of rectal bleeding caused by Goligher grade 4 hemorrhoids, where surgery is contraindicated.
Methods: Between 2019 and 2024, 18 patients (11 males, 7 females) with a mean age of 65±10.3 years were included in the study.

Background Endovascular thrombectomy (EVT) is an effective method for vertebrobasilar artery occlusion (VBAO) in patients with moderate to severe deficits but has unclear benefits in patients with low National Institutes of Health Stroke Scale (NIHSS) scores at hospital admission. Purpose To compare the clinical outcomes of best medical management (BMM) alone versus BMM and early EVT (door-to-puncture time [DPT] ≤ 120 minutes) versus BMM and late EVT (DPT > 120 minutes) in patients with VBAO who have NIHSS scores of 10 or less at admission. Materials and Methods This retrospective study evaluated patients with VBAO and admission NIHSS score of 10 or less who were seen at 65 stroke centers in China from December 2015 to June 2022.

Despite advances in procedural techniques and equipment, postdural puncture headache (PDPH) remains a serious complication of labour epidural analgesia after accidental dural puncture (ADP). Often considered a temporary inconvenience, PDPH can be debilitating in the short term. It can also be associated with chronic manifestations and serious complications.

Background: To evaluate the prognostic effect of endovascular treatment (EVT) in patients with acute base artery occlusion (ABAO) within 24 h of onset, and analyze the factors related to prognosis.
Methods: A retrospective analysis was conducted on all ABAO patients who received EVT within 24 h of onset in the neurology department of Baotou Central Hospital in Inner Mongolia from May 2016 to October 2022. Good prognosis was defined as a Modified Rankin Scale (mRS) score of 0-3 and poor prognosis mRS score of 4-6 at 90 day follow-up, and factors related to prognosis were analyzed.
