Obesity is a risk factor intrinsic to the development of areas of atelectasis, especially when the patient undergoes to general anesthesia and, therefore, some groups of studies has been dedicated to studying such subject. The recently published letter to the editor comments on and points out some aspects regarding the article on the prevalence of atelectasis in the obese Grade III submitted to...

Massive pulmonary atelectasis is encountered in a variety of circunistances that predispose to, or produce bronchial obstruction. The obstructing agents may be tumors, intrinsic or extrinsic, foreign bodies, or abnormal secretions retained in the airways. Precipitating factors may be inhibition of the cough mechanism by drug or metabolic depression, reflex inhibition due to pain, or ineffective...

OBJECTIVES To analyze the effects of exposure to hyperoxia (100% oxygen) on the lung histoarchitecture of neonatal mice. METHODS Neonatal Balb/c mice were exposed to hyperoxia (HG) (100% oxygen) (n= 10) in a chamber (15 x 20 x 30 cm) for 24 hours with a flow of 2 L/min. The control group (CG) (n = 10) was exposed to normoxia in the same type of chamber and for the same time. After exposure, t...

Most patients undergoing surgical procedures need to be mechanically ventilated, because of the impact of several drugs administered at induction and during maintenance of general anaesthesia on respiratory function. Optimization of intraoperative mechanical ventilation can reduce the incidence of post-operative pulmonary complications and improve the patient's outcome. Preoxygenation at induct...

BACKGROUND This study aimed to propose a new surgical strategy, i.e., the transcervical video-assisted mediastinoscopic lymphadenectomy (VAMLA) with esophagectomy via the left transthoracic approach for patients with esophageal cancer (EC), and to compare the outcomes with those of esophagectomy via the right thoracic approach. METHODS From December 2014 to March 2016, 49 cases were enrolled ...
