Introduction: A critical review of the pulmonary complications associated with blind placement of narrow‐bore nasoenteric tubes (NETs) is discussed. Preventive measures and placement techniques are addressed to decrease patient morbidity and mortality. Methods: A thorough database review was conducted to identify all randomized controlled and retrospective trials specifically addressing pulmonary complications from narrow‐bore NET placement. Five unique studies, comprising more than 9900 NET placements, were identified. On the basis of the literature reviewed, the authors identified 3 major complications associated with blind NET placement: patient mortality directly resulting from NET misplacement, incidence of tracheopulmonary malpositioning, and correlation between NET misplacement and mechanical ventilation. Results: Of the 9931 NET placements reviewed, there were 187 total improper tube placements in the tracheobronchial tree, which translates to a 1.9% mean overall malposition rate. Of these 187 misplacements, there were 35 (18.7%) reported pneumothoraces, at least 5 of which resulted in patient death. NET malpositioning was reported in 13%–32% of subsequent repositioning attempts. This increased risk exposes the patient population to a cumulative mortality from tracheobronchial malpositioning approaching >20%. Unexpectedly, of the 187 total misplacements, 113 (60.4%) of the patients were mechanically ventilated. Conclusions: Practitioners need to be aware of the potential for pulmonary complications associated with blind NET placement. Changes in institutional protocol should be considered to minimize unnecessary risks. As with any procedure, experienced personnel should be primarily used for tube placement and responsible for assisting others with less familiarity to learn the proper methods.
Abstract-Peripheral nerve injuries lead to a variety of pathological conditions, including paresis or paralysis when the injury involves motor axons. We have been studying ways to enhance the regeneration of peripheral nerves using daily electrical stimulation (ES) following a facial nerve crush injury. In our previous studies, ES was not initiated until 24 h after injury. The current experiment tested whether ES administered immediately following the crush injury would further decrease the time for complete recovery from facial paralysis. Rats received a unilateral facial nerve crush injury and an electrode was positioned on the nerve proximal to the crush site. Animals received daily 30 min sessions of ES for 1 d (day of injury only), 2 d, 4 d, 7 d, or daily until complete functional recovery. Untreated animals received no ES. Animals were observed daily for the return of facial function. Our findings demonstrated that one session of ES was as effective as daily stimulation at enhancing the recovery of most functional parameters. Therefore, the use of a single 30 min session of ES as a possible treatment strategy should be studied in human patients with paralysis as a result of acute nerve injuries.
The management of fecal incontinence is a struggle to maintain patient hygiene and limit the transmission of nosocomial infections. Intrarectal devices that cause diversion and collection of the fecal stream have been used with increasing frequency. This method can effectively control patient waste if used in an appropriate setting. We examine a series of 3 patients in whom rectal trauma resulting in life-threatening hemorrhage was associated with use of the ConvaTec Flexi-Seal fecal management system. In 2 patients there was a history of traumatic removal, and the third developed a rectal pressure ulcer associated with use of this device. All 3 patients required surgical or endoscopic intervention to achieve hemostasis. Although effective, the Flexi-Seal fecal management system should be used with caution to avoid rectal trauma. Injury is most likely to occur because of traumatic removal or rectal ulceration secondary to pressure necrosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
