Smart stethoscope gets FDA stamp of approval

From CNN:

Eko Devices, a smart medical device startup, announced on Wednesday that its Eko Core product has been cleared by the FDA. That means doctors around the country can use the technology on patients.

Part of CNNMoney’s Upstart 30, the company developed a device that turns “normal” stethoscopes into intelligent ones. By inserting the Eko Core into the tubing of a traditional device, doctors can take digital recordings of patient heartbeats using Bluetooth technology. The recordings are wirelessly transmitted to Eko’s HIPAA-compliant smartphone app and web portal.

The efficacy and safety of prehospital therapeutic hypothermia in patients with out-of-hospital cardiac arrest: A systematic review and meta-analysis

From Resuscitation:

Background

The benefit of therapeutic hypothermia (TH) to patients suffering out-of-hospital cardiac arrest (OHCA) has been well established. However, the effect of prehospital cooling remains unclear. We aimed to investigate the efficacy and safety of prehospital TH for OHCA patients by conducting a systematic review of randomised controlled trials (RCTs).

Methods

The MEDLINE, EMbase and CENTRAL databases were searched for publications from inception to April 2015. RCTs that compared cooling with no cooling in a prehospital setting among adults with OHCA were eligible for inclusion. Random- and fixed-effect models were used depending on inter-study heterogeneity.

Results

Eight trials that recruited 2379 participants met the inclusion criteria. Prehospital TH was significantly associated with a lower temperature at admission (mean difference (MD) −0.94; 95% confidence interval (CI) −1.06 to −0.82). However, survival upon admission (Risk ratio (RR) 1.01, 95%CI 0.98–1.04), survival at discharge (RR 1.02, 95%CI 0.91–1.14), in-hospital survival (RR 1.05, 95%CI 0.92–1.19) and good neurological function recovery (RR 1.06, 95% CI 0.91–1.23) did not differ between the TH-treated and non-treated groups. Prehospital cooling increased the incidence of recurrent arrest (RR 1.23, 95%CI 1.02–1.48) and decreased the PH at admission (MD −0.04, 95%CI −0.07 to −0.02). Pulmonary oedema did not differ between the arms (RR 1.02, 95%CI 0.67–1.57). None of the potentially controversial issues (cooling methods, time of inducing TH, the proportion of continuing cooling in hospital, actual prehospital infusion volume and primary cardiac rhythms) affected the efficacy.

Conclusion

Evidence does not support the administration of prehospital TH to patients with OHCA.

Drones: The (Possible) Future of Medicine

From Emergency Medicine News:

“I think that health care providers, especially those in critical access and remote areas, really need to think about this and talk about this. I think this needs to be brought up at society meetings where we’re dealing with conditions where there’s sensitive time management — in stroke, in STEMI, and trauma — and raise an awareness with our elected officials that when you’re thinking about modifying legislation as it relates to unmanned aerial vehicles, don’t leave the medical people out,” he said.
