A simple procedure gone wrong: pneumothorax after inadvertent transbronchial nasogastric tube insertion necessitating operative management

Situations and Risk Factors of Unplanned Extubation of Nasogastric Tubes in Inpatients: A Retrospective Study

OBJECTIVE

The aim of the study is to understand whether the risk factors of the unplanned extubation (UE) of nasogastric (NG) tubes vary among different inpatient situations.

METHODS

Inpatients who experienced UE between 2009 and 2022 at a medical center were selected, and electronic medical records were used to collect patient background data and their conditions during UE. A total of 302 patients were included in our analysis.

RESULTS

Conscious patients were at greater risk of UE when coughing, scratching their nose, blowing their nose, or sneezing than those who were confused (odds ratio [OR] = 0.07, P < 0.001) and those who were drowsy or comatose (OR = 0.15, P = 0.026). During activity, repositioning, bathing, or changing incontinence pads, the risk of UE was higher in patients whose hands were not restrained at the time of UE than in those whose hands were restrained (OR = 0.05, P = 0.004), higher in those with companions than in those without companions (OR = 7.78, P = 0.002), and higher in those with longer NG tube placement time (OR = 1.05, P = 0.008). Accidental extubation (OR = 2.62, P = 0.007) occurred more frequently during activity, repositioning, bathing, or changing incontinence pads.

CONCLUSIONS

There is an increased risk of UE in conscious patients during activity, repositioning, bathing, or changing incontinence pads. Patients inserted with an NG tube for a longer period of time were at greater risk of accidental extubation during activity, repositioning, bathing, or changing incontinence pads irrespective of whether a companion could aid them if their hands were or were not restrained.

Nasogastric tube placement perforating the nasopharynx causing mediastinal passage and feeding into the pleural space

A mid-60s female with known primary progressive multiple sclerosis was admitted to our hospital with aspiration pneumonia. Due to reduced consciousness, a nasogastric (NG) tube was inserted for feeding. A chest x-ray (CXR) report from a thoracic radiologist confirmed an atypical tip position due to a hiatus hernia but concluded it was almost certainly within the stomach. However, after deteriorating on feed commencement, a CT scan of the chest confirmed the tube had perforated the nasopharynx and run parallel to the oesophagus through the mediastinum into the right pleural space. The patient subsequently developed an empyema and pneumothorax, requiring multiple therapeutic interventions and a prolonged hospital stay. This case demonstrates how the routine insertion of an NG tube can lead to serious complications. Additionally, position check CXRs can be difficult to interpret, so the decision to use the tube must be made cautiously by the clinical team.

Hemothorax Following Traumatic Dobhoff Tube Insertion

Dobhoff tube is a specialized small-bore and flexible nasogastric tube that makes it more comfortable for placement than a usual nasogastric tube. Dobhoff tube insertion is commonly considered a relatively safe bedside procedure, but it is not without its associated risks. Inadvertent tracheobronchial placement of Dobhoff tube has been associated with severe complications, most notably pneumothorax. We present a rare cause of right-sided hemothorax following tracheobronchial insertion of a Dobhoff tube with a prolonged and arduous clinical course.
