Biodiversity of zooplankton (Rotifera, Cladocera and Copepoda) in the tributaries of Cheboksary Reservoir (Middle Volga, Russia).

Background: Freshwater zooplankton is an important component of the ecological communities of inland water bodies. It acts as an important part of the food web and participates in the self-purification processes of aquatic ecosystems. To study the abundance and distribution of species, a sampling event dataset was compiled and then published through GBIF.

[Improving surgical technique for tracheal resection with anastomosis].

Objective: To present modern aspects of improving surgical techniques in tracheal resection developed in recent years.

Material And Methods: The authors have the most extensive experience in tracheal surgery (>2.000 patients over the past 50 years).

[Early predictor of bronchial suture failure after pneumonectomy].

Objective: To identify the relationship between serum CRP/albumin and bronchial suture failure after pneumonectomy.

Material And Methods: A retrospective analysis included 100 patients who underwent pneumonectomy with extended lymph node dissection for lung cancer. Patients were divided into 2 groups depending on postoperative complications: group 1 - bronchial stump failure, group 2 - no similar complications.

Transsternal occlusion of main bronchi fistulae after pneumonectomy.

Objective: To summarize our experience in transsternal occlusion of main bronchus fistula.

Material And Methods: We have performed 146 transsternal occlusions of the main bronchi for the period from 1979 to 2018. There were 123 (84.

[Surgical treatment of extensive posttracheostomy tracheal stenosis using a new technique].

We report one-stage radical surgical treatment of a 54-year-old patient with extensive cicatricial posttracheostomy tracheal stenosis complicated by tracheomalacia of anterior tracheal wall and previous numerous unsuccessful endoscopic attempts of tracheal recanalization. A new method of prevention of tracheal anastomosis failure was applied.

[Minimally invasive thoracoscopic and robot-assisted lobectomy].

Objective: To compare the early outcomes of video-assisted and robot-assisted lobectomy.

Material And Methods: There were 74 robot-assisted lung resections for the period 2017-2018. Sixty-six patients underwent lobectomy and 8 - segmentectomy.

[Video-assisted thoracoscopic thymectomy in myasthenia gravis. New approach].

Aim: To present possibility and technical aspects of anesthetic management during video-assisted thoracoscopic thymectomy in patients with myasthenia gravis.

Material And Methods: The article describes the proposed modified anesthetic method that is suitable for video-assisted thoracoscopic thymectomy in patients with myasthenia gravis. Nine patients with myasthenia underwent VATS-thymectomy.

COMPARATIVE ASPECTS OF RESPIRATORY SUPPORT VIA LARINGEAL AIR DUCTS AND ENDOTRACHEAL TUBE FOR VIDEO-ASSISTED ONKOTHORACIC OPERATIONS.

Goal: To improve patient 's recovery after video-assisted thoracoscopic lobectomies (VATSL) by laryngeal mask using.

Methods: This is a comparative analysis of 74 patients underwent VATSL. In 37 patients anaesthesia consisted of sevoflurane and fentanyl, myorelaxant, respiratory support via independent ventilation of either lung.

[Anesthesia during video-assisted thoracoscopic lobectomy using laryngeal ductwork and auxiliary mechanical ventilation].

The article presents the experience of video-assisted thoracoscopic lobectomies in patients without endotracheal intubation and sparing of spontaneous breathing. The results of intraoperative monitoring and laboratory data of all perioperative period are described. In view of these data it was concluded that such approach can decline the severity of stress-response against surgical aggression in this group of patients.

[Anesthetic management of reconstructive surgery on the respiratory tract].

In the article provides an analysis of own of clinical experience peculiarities of carrying out of anesthesia, when performing 466 various tracheo-bronhoplastiс of operations for the period from 1979 to 2014 the year a one team of surgeons. Preoperative preparation, anesthesia and postoperative management of patients are key to improving treatment outcomes. Full arsenal of modern methods of ventilation lets you choose for each stage of surgery is most convenient for the surgeon and patient-safe way to maintain gas exchange.
