The method of choice of the surgical treatment of TEF associated with TS is a single-stage procedure in the patient who respires spontaneously.

Neither the demographic data nor the type of tracheostomy represented statistically significant risk factors. The risk factors for LTS were prolonged artificial pulmonary ventilation using the tracheostomy tube (p = 0.005) and repeated tracheostomy (p< 0.001). The mean onset of stenosis symptoms was 53.7 days (range 2-300 days), with a median of 58 days. Stenosis involved the trachea in 20 patients, subglottis in five cases, and glottis and subglottis in three cases. Seven patients (25%) underwent a tracheal resection and primary end-to-end reconstruction. One patient underwent laryngotracheoplasty with dilatation. The procedure was endoscopic in 18 patients (64.3%). Two patients (7.1%) received permanent tracheostomies.

Resection is the optimum therapeutic method for tracheal stenosis with low postoperative mortality and a small number of postoperative complications. Successful tracheal resection is a definitive solution in comparison with stent placement.

Background: The aim of this study was to compare plasma levobupivacaine concentrations in thoracic epidural and subpleural paravertebral analgesia. Methods: Forty-four patients indicated for open lung resection had an epidural catheter inserted preoperatively or a subpleural catheter surgically. A bolus of 0.25% levobupivacaine at a dosage of 0.5 mg × kg−1 was given after the thoracotomy closure. Plasma levobupivacaine level at 30 min was the primary outcome. Pharmacokinetic modeling was performed subsequently. Secondary outcomes included the quality of analgesia, complications, and patients’mobility. Results: Plasma concentrations were similar 30 min after application—0.389 mg × L−1 in the epidural and 0.318 mg × L−1 in the subpleural group (p = 0.33) and lower in the subpleural group at 120 min (p = 0.03). The areas under the curve but not maximum concentrations were lower in the subpleural group. The time to reach maximum plasma level was similar in both groups—27.6 vs. 24.2 min. No clinical symptoms of local anesthetic toxicity were recorded. Conclusions: Levobupivacaine systemic concentrations were low in both groups without the symptoms of toxicity. This dosage should be safe for postoperative analgesia after thoracotomy.
