Introduction Performing a routine postoperative chest X-ray (CXR) after general thoracic surgery is daily practice in many thoracic surgery departments. The quality, frequency of pathological findings and the clinical consequences have not been well evaluated. Furthermore, exposure to ionising radiation should be restricted to a minimum and therefore routine practice can be questioned. Methods As a hospital standard, each patient was given a routine CXR after opening of the pleura and inserting a chest tube...

BACKGROUND: Flexible bronchoscopy (FB) is commonly performed to assess, diagnose, and treat patients with respiratory disease, and is typically performed via transnasal or transoral approaches. FB can be performed via tracheal tubes in patients with tracheostomies; however, the safety and technical feasibility has not been established. The present study evaluates the safety and feasibility of performing FB via tracheal tubes. MATERIALS AND METHODS: A total of 45 patients underwent 56 procedures involving FB via tracheal tubes at a single institution from November 2013 to November 2014 and were included in this retrospective case series...

Fontan operation can be complicated by persistent chest tube output (CTO) leading to prolonged hospital length of stay (LOS). Postoperative sildenafil administration has been shown to improve clinical outcomes in selected patients after Fontan. We initiated a practice change utilizing intravenous (IV) sildenafil in early postoperative period in all patients undergoing Fontan operation with aim to decrease LOS and CTO. Nineteen patients (February 2014-May 2016) received 0.35 mg/kg sildenafil IV (three doses) followed by enteral, 1 mg/kg every eight hours until hospital discharge...

BACKGROUND: When intubating newborns, clinicians aim to position the endotracheal tube (ETT) tip in the midtrachea. The depth to which ETTs should be inserted is often estimated using the infant's weight. ETTs are frequently incorrectly positioned in newborns, most often inserted too far. Using the vocal cord guide (a mark at the distal end of the ETT) to guide insertion depth has been recommended. OBJECTIVE: To determine whether estimating ETT insertion depth using the vocal cord guide rather than weight results in more correctly positioned ETT tips...

Viral influenza is a seasonal infection associated with significant morbidity and mortality. Rapidly fatal hemorrhagic pneumonia has been described in previously healthy individuals with β-hemolytic Streptococcus pneumoniae in a small series of patients, but it is not common in patients coinfected with influenza B and β-hemolytic Streptococcus, particularly since influenza B is considered less pathogenic than influenza A. However, despite being uncommon, this coinfection seems to be associated with high morbidity and mortality, particularly in healthy individuals...
