Topic: Physiology in Non-intubated VATS

Institution: Department of Anesthesia NTUH Taipei TW



Nonintubated video-assisted thoracoscopic surgery(VATS)] is an emerging treatment modality for a wide variety of thoracic procedures. Under nonintubated VATS, the patients are able to breath spontaneously therefore FRC is better reserved. By surgically induced open pneumothorax, the operated lung could collapse progressively while the dependent lung is responsible for sufficiency of respiratory function. The understanding of respiratory physiology is essential to achieve the four pillars of nonintubated VATS: amnesia, analgesia, and areflexia, and adequate surgical window. This talk will review the basic physiology concepts that involved in the process of nonintubated VATS.

Topic: Physiological aspects of NITS from pathophysiological angle of view

Institution: Department of Pathophysiology Faculty of Medicine, Masaryk University Brno, CZ EU


NEURAL – peripheral and central, HUMORAL – local and systemic, VASCULAR – pulmonary and systemic, PHYSICAL – mechanical surgical touch, COMPENSATORY MECHANISMS – local and systemic, SIDE EFFECTS of local anesthetics and systemic administration of sedation
are considered in correlation with contemporary state of the art.

Topic : Seven as One. Questions on physiologigal operative to pathophysiologist

Institutions: Department of Surgery Faculty Hospital Brno, Masaryk University Faculty of
Medicine; CBC Vznik Initiative THORaxUN



Seven clinical questions on regulatory mechanisms due artificial pneumothorax in NITS patients:
1. Neural peripheral / central
2. Humoral local / systemic
3. Vascular pulmonary / systemic
4. Surgical touch (=mechanical irritation)
5. Compensatory process local / systemic
6. Side effects of regional anesthetics
(bupivacaine, lidocaine)
7. Side effects of drugs for sedation
These are particular components of ONE comprehensive process in undoubtedly need of interdisciplinary cooperation.
