Background: A tissue hemoglobin oxygen saturation (STO2) monitor was created to assess the perfusion status of a peripheral muscle bed using near infrared light to directly measure oxygen saturation in the microcirculation. Hypoperfusion has been noted when the STO2 is <75%. The use of this technology has not been tested in the prehospital setting. This pilot study was performed to assess the technology's ease of use in the field and to correlate STO2 readings with patient outcomes.
Methods: Hospital-based transport vehicles were equipped with STO2 monitors and personnel were asked to evaluate the functionality of the technology. Initial, average, and minimal STO2 values were collected and compared with data of the trauma registry.
Results: Forty five of 55 surveys were returned with 100% reporting ease of use and no reports of interference with monitors or avionics. Monitoring length averaged 16.9 minutes +/- 6.9 minutes. Forty-one patients had complete data sets and five deaths were reported for a mortality rate of 12%. STO2 endpoints revealed and increased risk of death for every 10% decrease in STO2.
Conclusion: The STO2 monitor can easily be used in the prehospital environment. In addition, initial recordings were significantly different between survivors and nonsurvivors with every 10% decrease in STO2 increasing mortality threefold. This monitor seems to give the prehospital provider a noninvasive tool for assessment of hypoperfusion in the field and may allow for earlier resuscitative efforts to commence.

Community Health Workers (CHWs) in low- and middle-income countries are essential in providing primary health care to remote communities. However, due to limited diagnostic tools, CHWs often struggle to correctly identify childhood illnesses, especially pneumonia. We conducted a prospective pilot study and used qualitative research methods to evaluate acceptability and feasibility of a multimodal pulse oximeter used by CHWs during their integrated community case management (iCCM) of childhood illness consultations in rural Burundi.

Aim: To perform a systematic review to investigate if the use of audio distraction reduces signs of stress and anxiety in paediatric patients undergoing dental treatment.
Materials And Methods: Search was made in electronic databases (MEDLINE, Scopus, Embase, Web of Science, Scielo, BVS, Springer Link, Science Direct, Cochrane Library, and grey literature) until March 11th, 2024. The eligibility criteria were: paediatric patients under dental treatment; use of audio as a distraction method; comparison between groups with and without use of audio distraction; Clinical trials.

Objectives: A conservative oxygenation strategy is recommended in adult and pediatric guidelines for the management of acute respiratory distress syndrome to reduce iatrogenic lung damage. In the recently reported Oxy-PICU trial, targeting peripheral oxygen saturations (Spo2) between 88% and 92% was associated with a shorter duration of organ support and greater survival, compared with Spo2 greater than 94%, in mechanically ventilated children following unplanned admission to PICU. We investigated whether this benefit was greater in those who had severely impaired oxygenation at randomization.

This double-blind randomized controlled trial investigated the effects of osteopathic manipulative treatment (OMT) on cardiac arrhythmias in patients with cardiac implantable electronic devices (CIEDs). Participants (n = 41) with CIEDs were randomly assigned to either the OMT group or the control group (light touch/sham) and received a one-time intervention. No significant change in arrhythmia burden was found in the 1 month following intervention ( = .

The purpose of this study was to evaluate how the first oral administration of suvorexant affects PSG results in patients with severe obstructive sleep apnea (OSA). Single-center, prospective study conducted in a nonrandomized, uncontrolled, unblinded fashion. Undiagnosed 64 patients with suspected OSA underwent first-night PSG, and 30 patients with severe OSA (Apnea Hypopnea Index [AHI] ≥ 30 events/h) underwent second-night PSG testing after administration of 15 mg suvorexant.
