The purpose of this clinical trial was to understand the effects of variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), pressure-controlled ventilation (PCV), and open surgery (Open Surgery). controlled ventilation (C-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), and pressure-controlled ventilation (PCV) for open surgery, video-assisted thoracoscopic surgery, and segmental lung resection. VATS), segmentectomy (Segmentectomy), lobectomy (Lobectomy), and pneumonectomy (Pneumonectomy) on oxygen saturation and pulmonary complications, and length of hospitalization.
The main question it aims to answer is: variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), and pressure-controlled ventilation (PCV).Does it decrease patient oxygen saturation, and does it increase pulmonary complications, length of hospitalization? Researchers compared variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C-VCV), and pressure-controlled ventilation (PCV) to compare them to see which mode of ventilation has the least physiologic disruption for the patient.
Participants will:
Select the appropriate surgical procedure according to the condition and be randomized to variable tidal volume ventilation (V-VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume- controlled ventilation (C-VCV), pressure-controlled ventilation (PCV), and were checked after surgery.
Patients' oxygen saturation, pulmonary complications, length of hospitalization were recorded
Patients requiring any of open surgery, television-assisted thoracoscopic surgery (VATS), segmental lung resection (Segmentectomy), lobectomy, and total lung resection (Pneumonectomy).
Patients who are able to receive any of the ventilation modes of controlled ventilation (C - VCV), pressure-regulated volume-controlled ventilation (PRVC), conventional volume-controlled ventilation (C - VCV), pressure-controlled ventilation (PCV), and variable tidal volume ventilation (V - VCV).
