Emergency Percutaneous Transtracheal Ventilation during Anesthesia Using Readily Available Equipment

Pediatric transtracheal and cricothyrotomy airway devices for emergency use: which are appropriate for infants and children?

“…Alternatively, if the VBM device (or an i.v. catheter) is interfaced with a jet ventilation system, successful ventilation is achieved (being mindful that this must be tightly secured so as to not be propelled out of the airway thus causing massive and perhaps fatal subcutaneous emphysema or pneumomediastinum) (41,42,42–45). A commercially available device designed for low pressure jet ventilation is available (Enk Oxygen Flow Modulation set; Cook Inc, Bloomington, IN, USA) but a ‘poor man’s’ version can be constructed by cutting a side hole in the oxygen tubing which is then intermittently occluded to divert flow into the catheter (Figure 4).…”

Percutaneous transtracheal emergency ventilation with a self‐made device in an animal model

“…Other self‐made equipments for percutaneous transtracheal oxygenation or ventilation are described in several case reports and have been tested especially in combination with anesthesia machines: deLisser et al used a tubing and needle set (with anesthesia machine adapter) which provides positive pressure lung inflation by activation of the oxygen flush valve of the anesthesia machine, whereas exhalation occurs passively (10). Scuderi et al tested in an animal model a modified mode of percutaneous transtracheal ventilation using readily available equipment combined with a standard anesthesia machine (11). For the sole purpose of oxygenation, the transtracheal needle can also be connected via a resuscitation bag to an oxygen supply (12,13).…”
