New sternal puncture needle.
The needles most commonly used for obtaining bone marrow aspirates from the sternum are the Salah and Klima needles. They were designed in the 1930s, and except for the introduction of different kinds of stops and guards there has been no change in their basic structure and design. These instruments are small, do not fit properly in the operator's hand, and the lack of a T-bar handle often make...
متن کاملBurns to be alive: a complication of transcutaneous cardiac stimulation
Figure 1 Two little third-degree skin burns under the breast following use of an external cardiac pacing device. External cardiac pacing devices (ECPDs) are commonly employed in emergency situations. The main indication for their use is untolerated bradycardia, especially in cases where other medical treatments have no effect [1]. Although the efficacy and safety of ECPDs are well documented, a...

متن کاملMeasurement of twitch transdiaphragmatic pressure: surface versus needle electrode stimulation.
The transdiaphragmatic pressure (Pdi) generated during bilateral supramaximal phrenic nerve stimulation at 1 Hz from surface stimulating electrodes was compared with pressures obtained from needle electrodes inserted under local anaesthesia. Surface electrodes were used to obtain diaphragmatic electromyograms and magnetometers to monitor rib cage and abdominal configuration. Twitch Pdi was reco...
متن کاملTranscutaneous electrical nerve stimulation
Transcutaneous electrical nerve stimulation (TENS) is a non-invasive analgesic technique that is used to relieve nociceptive, neuropathic, and musculoskeletal pain. During TENS, pulsed electrical currents are generated by a portable pulse generator and delivered across the intact surface of the skin via the selfadhering conducting pads called electrodes (Fig. 1). Patients can self-administer TE...
